Obsessive-compulsive disorder (OCD) is a chronic, debilitating neuropsychiatric disorder that affects 1% to 3% of the population worldwide.^1,2 Together, serotonin reuptake inhibitors (SRIs) and cognitive-behavior therapy (CBT) are considered the first-line treatment for OCD.³ In children and adults, CBT is considered at least as effective as pharmacotherapy.⁴ Despite being an effective treatment, CBT continues to have barriers to its widespread use, including limited availability of trained CBT therapists, delayed clinical response, and high costs.⁵

Only approximately one-half of patients with OCD respond to SRI therapy, and a considerable percentage (30% to 40%) show significant residual symptoms even after multiple trials of SRIs.^6-8 In addition, SRIs may have adverse effects (eg, sexual dysfunction, gastrointestinal symptoms) that impair patient adherence to these medications.⁹ Therefore, finding better treatment options is important for managing patients with OCD.

Augmentation strategies are recommended for patients who show partial response to SRI treatment or poor response to multiple SRIs. Augmentation typically includes incorporating additional medications with the primary drug with the goal of boosting the therapeutic efficacy of the primary drug. Typically, these additional medications have different mechanisms of action. However, there are no large-scale randomized controlled trials (RCTs) to inform treatment augmentation after first-line treatments for OCD produce suboptimal outcomes. The available evidence is predominantly based on small-scale RCTs, open-label trials, and case series.

In this article, we review the evidence for treatment augmentation strategies for OCD and summarize 8 studies that show promising results (Table^10-17). We focus only on pharmacologic agents and do not include other biological interventions, such as repetitive transcranial magnetic stimulation over supplementary motor area, ablative neurosurgery, or deep brain stimulation.

Numerous studies support the role of glutamate dysregulation in the pathophysiology of OCD. Cortico-striato-thalamo-cortical (CSTC) abnormalities play a major role in the pathophysiology of OCD as suggested by neuroimaging research studies that indicate glutamate is the fundamental neurotransmitter of the CSTC circuit. Dysregulation of glutamatergic signaling within this circuit has been linked to OCD. Patients with OCD have been found to have an increase of glutamate in the CSF. As a result, medications that affect glutamate levels can be used to treat patients with OCD who do not respond to first-line agents. In patients already taking SRIs, augmentation of glutamate-modulating medications can reduce OCD symptoms. As an uncompetitive antagonist of the N-methyl-d-aspartate (NMDA)-type glutamate receptor, amantadine has been proposed as 1 of these medications.

Naderi et al¹⁰ evaluated amantadine as augmentative therapy to fluvoxamine for treating patients with moderate to severe OCD.

Study design

• This 12-week, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of amantadine as an augmentative agent to fluvoxamine in 106 patients age 18 to 60 with moderate to severe OCD.
• Participants met DSM-5 criteria for OCD and had a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score >21. Participants were excluded if they had any substance dependence; an IQ <70; any other Axis I mental disorder; any serious cardiac, renal, or hepatic disease; had received psychotropic medications during the last 6 weeks, were pregnant or breastfeeding, or had rising liver transaminases to 3 times the upper limit of normal or higher.
• Participants received fluvoxamine 100 mg twice daily plus amantadine 100 mg/d, or fluvoxamine 100 mg twice daily plus placebo. All patients received fluvoxamine 100 mg/d for 28 days followed by 200 mg/d for the remainder of the trial.
• The primary outcome measure was difference in Y-BOCS total scores between the amantadine and placebo groups. The secondary outcome was the difference in Y-BOCS obsession and compulsion subscale scores.

Outcomes

• Patients who received amantadine augmentation experienced a significant reduction in Y-BOCS total score (P < .001) and obsession subscale score (P < .01).
• The amantadine group showed good tolerability and safety. There were no clinically significant adverse effects.

• Amantadine is an effective adjuvant to fluvoxamine for reducing OCD symptoms.

Conclusion

• Ondansetron and granisetron can be beneficial as an augmentation strategy for patients with treatment-resistant OCD.

Comparing the efficacy of ondansetron and granisetron augmentation in treatment-resistant obsessive-compulsive disorder: a randomized double-blind placebo-controlled study. Int Clin Psychopharmacol. 2019;34(5):222- 233. doi:10.1097/YIC.0000000000000267

Although selective serotonin reuptake inhibitors (SSRIs) are considered a first-line treatment when teamed with CBT and antipsychotic augmentation, symptom resolution is not always achieved, and treatment resistance is a common problem. Sharafkhah et al¹¹ compared the efficacy of ondansetron and granisetron augmentation specifically for patients with treatment-resistant OCD.

Study Design

• In this 18-week, randomized, double-blind, placebo-controlled study, 135 patients with treatment-resistant OCD who were previously treated with a combination of an SSRI and an antipsychotic received augmentation with ondansetron (n = 45, 4 mg/d), granisetron (n = 45, 2 mg/d), or placebo.
• Patients were rated using Y-BOCS every 2 weeks during phase I (intervention period), which lasted 14 weeks. After completing the intervention, patients were followed for 4 more weeks during phase II (discontinuation period).
• The aim of this study was to determine the safety, efficacy, and tolerability of ondansetron vs granisetron as augmentation for patients with treatment-resistant OCD. A secondary aim was to determine the rate of relapse of OCD symptoms after discontinuing ondansetron as compared with granisetron at 4 weeks after intervention.

Outcomes

• At Week 14, the reductions in Y-BOCS scores in the ondansetron, granisetron, and placebo groups were 41.5%, 39.7%, and 15.2%, respectively (P = .001). The reduction in Y-BOCS score in the ondansetron and granisetron groups was significantly greater than placebo at all phase I visits.
• Complete response was higher in the ondansetron group compared with the granisetron group (P = .041).
• Y-BOCS scores increased in both the ondansetron and granisetron groups during the discontinuation phase, but OCD symptoms were not significantly exacerbated.

Conclusion

• Ondansetron and granisetron can be beneficial as an augmentation strategy for patients with treatment-resistant OCD.

Increased glutamate levels in CSF, glutamatergic overactivity, and polymorphisms of genes coding the NMDA receptor have been shown to contribute to the occurrence of OCD. Memantine is a noncompetitive antagonist of the NMDA receptor. Various control trials have shown augmentation with memantine 5 mg/d to 20 mg/d significantly reduced symptom severity in patients with moderate to severe OCD. Modarresi et al¹² evaluated memantine as a treatment option for patients with severe OCD who did not respond to SRI monotherapy.

Study design

• This 12-week, double-blind, randomized, placebo-controlled trial evaluated the efficacy of memantine augmentation in 32 patients age 18 to 40 who met DSM-5 criteria for OCD, had a Y-BOCS score ≥24, and no psychiatric comorbidity. Participants had not responded to ≥3 adequate trials (minimum 3 months) of SRI therapy, 1 of which was clomipramine.
• Individuals were excluded if they were undergoing CBT; had an additional anxiety disorder, mood disorder, or current drug or alcohol use disorder, or any systemic disorder; had a history of seizures; were pregnant or breastfeeding; or had a history of memantine use.
• Participants already receiving the maximum tolerated dose of an SRI received augmentation with memantine 20 mg/d or placebo.
• The primary outcome measure was change in Y-BOCS score from baseline. The secondary outcome was the number of individuals who achieved treatment response (defined as ≥35% reduction in Y-BOCS score).

Continue to: Outcomes...

Outcomes

• There was a statistically significant difference in Y-BOCS score in patients treated with memantine at Week 8 and Week 12 vs those who received placebo. By Week 8, 17.2% of patients in the memantine group showed a decrease in Y-BOCS score, compared with -0.8% patients in the placebo group. The difference became more significant by Week 12, with 40.9% in the memantine group showing a decrease in Y-BOCS score vs -0.3% in the placebo group. This resulted in 73.3% of patients achieving treatment response.
• Eight weeks of memantine augmentation was necessary to observe a significant improvement in OCD symptoms, and 12 weeks was needed for treatment response.
• The mean Y-BOCS total score decreased significantly in the memantine group from Week 4 to Week 8 (16.8%) and again from Week 8 to Week 12 (28.5%).
• The memantine group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• Memantine augmentation in patients with severe OCD who do not respond to an SRI is effective and well-tolerated.

Studies have demonstrated the involvement of the amygdala, medial and lateral orbitofrontal cortex, and dorsal anterior cingulate cortex in OCD. Additionally, studies have also investigated the role of serotonin, dopamine, and glutamate system dysregulation in the pathology of OCD.

The 5-HT3 receptors are ligand-gated ion channels found in the prefrontal cortex, amygdala, and hippocampus. Studies of 5-HT3 receptor antagonists such as ondansetron and granisetron have shown beneficial results in augmentation with SSRIs for patients with OCD.¹¹ Tropisetron, a 5-HT3 receptor antagonist, is highly lipophilic and able to cross the blood brain barrier. It also has dopamine-inhibiting properties that could have benefits in OCD management. Shalbafan et al¹³ evaluated the efficacy of tropisetron augmentation to fluvoxamine for patients with OCD.

Study design

• In a 10-week, randomized, double-blind, placebo-controlled, parallel-group trial, 108 individuals age 18 to 60 who met DSM-5 criteria for OCD and had a Y-BOCS score >21 received fluvoxamine plus tropisetron or fluvoxamine plus placebo. A total of 48 (44.4%) participants in each group completed the trial. Participants were evaluated using the Y-BOCS scale at baseline and at Week 4 and Week 10.
• The primary outcome was decrease in total Y-BOCS score from baseline to Week 10. The secondary outcome was the difference in change in Y-BOCS obsession and compulsion subscale scores between the groups.

Outcomes

• The Y-BOCS total score was not significantly different between the 2 groups (P = .975). Repeated measures analysis of variance determined a significant effect for time in both tropisetron and placebo groups (Greenhouse-Geisser F [2.72–2303.84] = 152.25, P < .001; and Greenhouse-Geisser F [1.37–1736.81] = 75.57, P < .001, respectively). At Week 10, 35 participants in the tropisetron group and 19 participants in the placebo group were complete responders.
• The baseline Y-BOCS obsession and compulsion subscales did not significantly differ between treatment groups.

Conclusion

• Compared with participants in the placebo group, those in the tropisetron group experienced a significantly greater reduction in OCD symptoms as measured by Y-BOCS score. More participants in the tropisetron group experienced complete response and remission.
• This study demonstrated that compared with placebo, when administered as augmentation with fluvoxamine, tropisetron can have beneficial effects for patients with OCD.

Nutraceuticals such as glycine, milk thistle, myoinositol, and serotonin (5-hydroxytryptophan) have been proposed as augmentation options for OCD. Yousefzadeh et al¹⁴ investigated the effectiveness of using 5-hydroxytryptophan in treating OCD.

Study design

• In a 12-week, randomized, double-blind study, 60 patients who met DSM-5 criteria for moderate to severe OCD (Y-BOCS score >21) were randomly assigned to receive fluoxetine plus 5-hydroxytryptophan 100 mg twice daily or fluoxetine plus placebo.
• All patients were administered fluoxetine 20 mg/d for the first 4 weeks of the study followed by fluoxetine 60 mg/d for the remainder of the trial.
• Symptoms were assessed using the Y-BOCS at baseline, Week 4, Week 8, and Week 12.
• The primary outcome measure was the difference between the 2 groups in change in Y-BOCS total score from baseline to the end of the trial. Secondary outcome measures were the differences in the Y-BOCS obsession and compulsion subscale scores from baseline to Week 12.

Outcomes

• Compared to the placebo group, the 5-hydroxytryptophan group experienced a statistically significant greater improvement in Y-BOCS total score from baseline to Week 8 (P = .002) and Week 12 (P < .001).
• General linear model repeated measure showed significant effects for time × treatment interaction on Y-BOCS total (F = 12.07, df = 2.29, P < .001), obsession subscale (F = 8.25, df = 1.91, P = .001), and compulsion subscale scores (F = 6.64, df = 2.01, P = .002).
• The 5-hydroxytryptophan group demonstrated higher partial and complete treatment response rates (P = .032 and P = .001, respectively) as determined by change in Y-BOCS total score.
• The 5-hydroxytryptophan group showed a significant improvement from baseline to Week 12 in Y-BOCS obsession subscale score (5.23 ± 2.33 vs 3.53 ± 2.13, P = .009).
• There was a significant change from baseline to the end of the trial in the Y-BOCS compulsion subscale score (3.88 ± 2.04 vs 2.30 ± 1.37, P = .002).

Conclusion

• This trial demonstrated the potential benefits of 5-hydroxytryptophan in combination with fluoxetine for patients with OCD.

Glutamatergic dysfunction has been identified as a potential cause of OCD. Studies have found elevated levels of glutamatergic transmission in the cortical-striatal-thalamic circuit of the brain and elevated glutamate concentration in the CSF in patients with OCD. Pregabalin has multiple mechanisms of action that inhibit the release of glutamate. Mowla et al¹⁵ evaluated pregabalin as an augmentation treatment for resistant OCD.

Study design

• This 12-week, double-blind, placebo-controlled clinical trial evaluated the efficacy of adjunctive pregabalin in 56 patients who met DSM-5 criteria for OCD and had not responded to ≥12 weeks of treatment with an adequate and stable dose of sertraline (baseline Y-BOCS score ≥18).
• Individuals who had other major psychiatric disorders, major medical problems, were pregnant, or had past substance or alcohol abuse were excluded.
• Participants were randomly assigned to receive sertraline plus pregabalin (n = 28) or sertraline plus placebo (n = 28). Mean sertraline dosage was 256.5 mg/d; range was 100 mg/d to 300 mg/d. Pregabalin was started at 75 mg/d and increased by 75 mg increments weekly. The mean dosage was 185.9 mg/d; range was 75 mg/d to 225 mg/d.
• The primary outcome measure was change in Y-BOCS score. A decrease >35% in Y-BOCS score was considered a significant response rate.

Outcomes

• There was a statistically significant decrease in Y-BOCS score in patients who received pregabalin. In the pregabalin group, 57.14% of patients (n = 16) showed a >35% decrease in Y-BOCS score compared with 7.14% of patients (n = 2) in the placebo group (P < .01).
• The pregabalin group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• In patients with treatment-resistant OCD who did not respond to sertraline monotherapy, augmentation with pregabalin significantly decreases Y-BOCS scores compared with placebo.

Combined fluvoxamine and extended-release methylphenidate improved treatment response compared to fluvoxamine alone in patients with treatment-refractory obsessive-compulsive disorder: a randomized double-blind, placebocontrolled study. Eur Neuropsychopharmacol. 2019;29(3):397-404. doi:10.1016/j.euroneuro. 2018.12.010

Recent evidence suggests dysregulation of serotonin and dopamine in patients with OCD. Methylphenidate is a dopamine and norepinephrine inhibitor and releaser. A limited number of studies have suggested stimulants might be useful for OCD patients. Zheng et al¹⁶ conducted a pilot trial to determine whether methylphenidate augmentation may be of benefit in the management of outpatients with OCD.

Study design

• In an 8-week, double-blind, randomized, placebo-controlled trial, 44 patients (29 [66%] men, with a mean [SD] age of 24.7 [6]) with treatment-refractory OCD were randomized to receive fluvoxamine 250 mg/d plus methylphenidate extended-release (MPH-ER) 36 mg/d or fluvoxamine 250 mg/d plus placebo. The MPH-ER dose was 18 mg/d for the first 4 weeks and 36 mg/d for the rest of the trial.
• Biweekly assessments consisted of scores on the Y-BOCS, Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Rating Scale (HAM-A).
• The primary outcomes were improvement in Y-BOCS score and the clinical response rate. Secondary outcomes included a change in score on the Y-BOCS subscales, HARS, and HAM-A. Data were analyzed with the intention-to-treat sample.

Outcomes

• Forty-one patients finished the trial. The baseline Y-BOCS total scores and subscale scores did not differ significantly between the 2 groups.
• Improvements in Y-BOCS total score and obsession subscale score were more prominent in the fluvoxamine plus MPH-ER group compared with the placebo group (P < .001).
• HDRS score decreased in both the placebo and MPH-ER groups. HAM-A scores decreased significantly in the MPH-ER plus fluvoxamine group compared with the placebo group.

Conclusion

• This study demonstrated that the combination of fluvoxamine and MPH-ER produces a higher and faster response rate than fluvoxamine plus placebo in patients with OCD.

Glutamate dysregulation is implicated in the pathogenesis of OCD. Glutamate-modulating agents have been used to treat OCD. Studies have shown L-carnosine has a neuroprotective role via its modulatory effect on glutamate. Arabzadeh et al¹⁷ evaluated the efficacy of L-carnosine as an adjuvant to fluvoxamine for treating OCD.

Study design

• This 10-week, randomized, double-blind, placebo-controlled trial evaluated the efficacy of adjunctive L-carnosine in 40 patients age 18 to 60 who met DSM-5 criteria for OCD and had moderate to severe OCD (Y-BOCS score ≥21).
• Individuals with any other DSM-5 major psychiatric disorders, serious medical or neurologic illness, substance dependence (other than caffeine or nicotine), mental retardation (based on clinical judgment), were pregnant or breastfeeding, had any contraindication for the use of L‐carnosine or fluvoxamine, or received any psychotropic drugs in the previous 6 weeks were excluded.
• Participants received fluvoxamine 100 mg/d for the first 4 weeks and 200 mg/d for the next 6 weeks plus either L-carnosine 500 mg twice daily or placebo. This dosage of L-carnosine was chosen because previously it had been tolerated and effective.
• The primary outcome measure was difference in Y-BOCS total scores. Secondary outcomes were differences in Y-BOCS obsession and compulsion subscale scores and differences in change in score on Y-BOCS total and subscale scores from baseline.

Outcomes

• The L-carnosine group experienced a significant decrease in Y-BOCS total score (P < .001), obsession subscale score (P < .01), and compulsion subscale score (P < .01).
• The group that received fluvoxamine plus L-carnosine also experienced a more complete response (P = .03).
• The L-carnosine group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• L-carnosine significantly reduces OCD symptoms when used as an adjuvant to fluvoxamine.

Studies have demonstrated the involvement of the amygdala, medial and lateral orbitofrontal cortex, and dorsal anterior cingulate cortex in OCD. Additionally, studies have also investigated the role of serotonin, dopamine, and glutamate system dysregulation in the pathology of OCD.

The 5-HT3 receptors are ligand-gated ion channels found in the prefrontal cortex, amygdala, and hippocampus. Studies of 5-HT3 receptor antagonists such as ondansetron and granisetron have shown beneficial results in augmentation with SSRIs for patients with OCD.¹¹ Tropisetron, a 5-HT3 receptor antagonist, is highly lipophilic and able to cross the blood brain barrier. It also has dopamine-inhibiting properties that could have benefits in OCD management. Shalbafan et al¹³ evaluated the efficacy of tropisetron augmentation to fluvoxamine for patients with OCD.

Study design

• In a 10-week, randomized, double-blind, placebo-controlled, parallel-group trial, 108 individuals age 18 to 60 who met DSM-5 criteria for OCD and had a Y-BOCS score >21 received fluvoxamine plus tropisetron or fluvoxamine plus placebo. A total of 48 (44.4%) participants in each group completed the trial. Participants were evaluated using the Y-BOCS scale at baseline and at Week 4 and Week 10.
• The primary outcome was decrease in total Y-BOCS score from baseline to Week 10. The secondary outcome was the difference in change in Y-BOCS obsession and compulsion subscale scores between the groups.

Outcomes

• The Y-BOCS total score was not significantly different between the 2 groups (P = .975). Repeated measures analysis of variance determined a significant effect for time in both tropisetron and placebo groups (Greenhouse-Geisser F [2.72–2303.84] = 152.25, P < .001; and Greenhouse-Geisser F [1.37–1736.81] = 75.57, P < .001, respectively). At Week 10, 35 participants in the tropisetron group and 19 participants in the placebo group were complete responders.
• The baseline Y-BOCS obsession and compulsion subscales did not significantly differ between treatment groups.

Conclusion

• Compared with participants in the placebo group, those in the tropisetron group experienced a significantly greater reduction in OCD symptoms as measured by Y-BOCS score. More participants in the tropisetron group experienced complete response and remission.
• This study demonstrated that compared with placebo, when administered as augmentation with fluvoxamine, tropisetron can have beneficial effects for patients with OCD.

Nutraceuticals such as glycine, milk thistle, myoinositol, and serotonin (5-hydroxytryptophan) have been proposed as augmentation options for OCD. Yousefzadeh et al¹⁴ investigated the effectiveness of using 5-hydroxytryptophan in treating OCD.

Study design

• In a 12-week, randomized, double-blind study, 60 patients who met DSM-5 criteria for moderate to severe OCD (Y-BOCS score >21) were randomly assigned to receive fluoxetine plus 5-hydroxytryptophan 100 mg twice daily or fluoxetine plus placebo.
• All patients were administered fluoxetine 20 mg/d for the first 4 weeks of the study followed by fluoxetine 60 mg/d for the remainder of the trial.
• Symptoms were assessed using the Y-BOCS at baseline, Week 4, Week 8, and Week 12.
• The primary outcome measure was the difference between the 2 groups in change in Y-BOCS total score from baseline to the end of the trial. Secondary outcome measures were the differences in the Y-BOCS obsession and compulsion subscale scores from baseline to Week 12.

Outcomes

• Compared to the placebo group, the 5-hydroxytryptophan group experienced a statistically significant greater improvement in Y-BOCS total score from baseline to Week 8 (P = .002) and Week 12 (P < .001).
• General linear model repeated measure showed significant effects for time × treatment interaction on Y-BOCS total (F = 12.07, df = 2.29, P < .001), obsession subscale (F = 8.25, df = 1.91, P = .001), and compulsion subscale scores (F = 6.64, df = 2.01, P = .002).
• The 5-hydroxytryptophan group demonstrated higher partial and complete treatment response rates (P = .032 and P = .001, respectively) as determined by change in Y-BOCS total score.
• The 5-hydroxytryptophan group showed a significant improvement from baseline to Week 12 in Y-BOCS obsession subscale score (5.23 ± 2.33 vs 3.53 ± 2.13, P = .009).
• There was a significant change from baseline to the end of the trial in the Y-BOCS compulsion subscale score (3.88 ± 2.04 vs 2.30 ± 1.37, P = .002).

Conclusion

• This trial demonstrated the potential benefits of 5-hydroxytryptophan in combination with fluoxetine for patients with OCD.

Glutamatergic dysfunction has been identified as a potential cause of OCD. Studies have found elevated levels of glutamatergic transmission in the cortical-striatal-thalamic circuit of the brain and elevated glutamate concentration in the CSF in patients with OCD. Pregabalin has multiple mechanisms of action that inhibit the release of glutamate. Mowla et al¹⁵ evaluated pregabalin as an augmentation treatment for resistant OCD.

Study design

• This 12-week, double-blind, placebo-controlled clinical trial evaluated the efficacy of adjunctive pregabalin in 56 patients who met DSM-5 criteria for OCD and had not responded to ≥12 weeks of treatment with an adequate and stable dose of sertraline (baseline Y-BOCS score ≥18).
• Individuals who had other major psychiatric disorders, major medical problems, were pregnant, or had past substance or alcohol abuse were excluded.
• Participants were randomly assigned to receive sertraline plus pregabalin (n = 28) or sertraline plus placebo (n = 28). Mean sertraline dosage was 256.5 mg/d; range was 100 mg/d to 300 mg/d. Pregabalin was started at 75 mg/d and increased by 75 mg increments weekly. The mean dosage was 185.9 mg/d; range was 75 mg/d to 225 mg/d.
• The primary outcome measure was change in Y-BOCS score. A decrease >35% in Y-BOCS score was considered a significant response rate.

Outcomes

• There was a statistically significant decrease in Y-BOCS score in patients who received pregabalin. In the pregabalin group, 57.14% of patients (n = 16) showed a >35% decrease in Y-BOCS score compared with 7.14% of patients (n = 2) in the placebo group (P < .01).
• The pregabalin group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• In patients with treatment-resistant OCD who did not respond to sertraline monotherapy, augmentation with pregabalin significantly decreases Y-BOCS scores compared with placebo.

Combined fluvoxamine and extended-release methylphenidate improved treatment response compared to fluvoxamine alone in patients with treatment-refractory obsessive-compulsive disorder: a randomized double-blind, placebocontrolled study. Eur Neuropsychopharmacol. 2019;29(3):397-404. doi:10.1016/j.euroneuro. 2018.12.010

Recent evidence suggests dysregulation of serotonin and dopamine in patients with OCD. Methylphenidate is a dopamine and norepinephrine inhibitor and releaser. A limited number of studies have suggested stimulants might be useful for OCD patients. Zheng et al¹⁶ conducted a pilot trial to determine whether methylphenidate augmentation may be of benefit in the management of outpatients with OCD.

Study design

• In an 8-week, double-blind, randomized, placebo-controlled trial, 44 patients (29 [66%] men, with a mean [SD] age of 24.7 [6]) with treatment-refractory OCD were randomized to receive fluvoxamine 250 mg/d plus methylphenidate extended-release (MPH-ER) 36 mg/d or fluvoxamine 250 mg/d plus placebo. The MPH-ER dose was 18 mg/d for the first 4 weeks and 36 mg/d for the rest of the trial.
• Biweekly assessments consisted of scores on the Y-BOCS, Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Rating Scale (HAM-A).
• The primary outcomes were improvement in Y-BOCS score and the clinical response rate. Secondary outcomes included a change in score on the Y-BOCS subscales, HARS, and HAM-A. Data were analyzed with the intention-to-treat sample.

Outcomes

• Forty-one patients finished the trial. The baseline Y-BOCS total scores and subscale scores did not differ significantly between the 2 groups.
• Improvements in Y-BOCS total score and obsession subscale score were more prominent in the fluvoxamine plus MPH-ER group compared with the placebo group (P < .001).
• HDRS score decreased in both the placebo and MPH-ER groups. HAM-A scores decreased significantly in the MPH-ER plus fluvoxamine group compared with the placebo group.

Conclusion

• This study demonstrated that the combination of fluvoxamine and MPH-ER produces a higher and faster response rate than fluvoxamine plus placebo in patients with OCD.

Glutamate dysregulation is implicated in the pathogenesis of OCD. Glutamate-modulating agents have been used to treat OCD. Studies have shown L-carnosine has a neuroprotective role via its modulatory effect on glutamate. Arabzadeh et al¹⁷ evaluated the efficacy of L-carnosine as an adjuvant to fluvoxamine for treating OCD.

Study design

• This 10-week, randomized, double-blind, placebo-controlled trial evaluated the efficacy of adjunctive L-carnosine in 40 patients age 18 to 60 who met DSM-5 criteria for OCD and had moderate to severe OCD (Y-BOCS score ≥21).
• Individuals with any other DSM-5 major psychiatric disorders, serious medical or neurologic illness, substance dependence (other than caffeine or nicotine), mental retardation (based on clinical judgment), were pregnant or breastfeeding, had any contraindication for the use of L‐carnosine or fluvoxamine, or received any psychotropic drugs in the previous 6 weeks were excluded.
• Participants received fluvoxamine 100 mg/d for the first 4 weeks and 200 mg/d for the next 6 weeks plus either L-carnosine 500 mg twice daily or placebo. This dosage of L-carnosine was chosen because previously it had been tolerated and effective.
• The primary outcome measure was difference in Y-BOCS total scores. Secondary outcomes were differences in Y-BOCS obsession and compulsion subscale scores and differences in change in score on Y-BOCS total and subscale scores from baseline.

Outcomes

• The L-carnosine group experienced a significant decrease in Y-BOCS total score (P < .001), obsession subscale score (P < .01), and compulsion subscale score (P < .01).
• The group that received fluvoxamine plus L-carnosine also experienced a more complete response (P = .03).
• The L-carnosine group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• L-carnosine significantly reduces OCD symptoms when used as an adjuvant to fluvoxamine.

Obsessive-compulsive disorder (OCD) is a chronic, debilitating neuropsychiatric disorder that affects 1% to 3% of the population worldwide.^1,2 Together, serotonin reuptake inhibitors (SRIs) and cognitive-behavior therapy (CBT) are considered the first-line treatment for OCD.³ In children and adults, CBT is considered at least as effective as pharmacotherapy.⁴ Despite being an effective treatment, CBT continues to have barriers to its widespread use, including limited availability of trained CBT therapists, delayed clinical response, and high costs.⁵

Only approximately one-half of patients with OCD respond to SRI therapy, and a considerable percentage (30% to 40%) show significant residual symptoms even after multiple trials of SRIs.^6-8 In addition, SRIs may have adverse effects (eg, sexual dysfunction, gastrointestinal symptoms) that impair patient adherence to these medications.⁹ Therefore, finding better treatment options is important for managing patients with OCD.

Augmentation strategies are recommended for patients who show partial response to SRI treatment or poor response to multiple SRIs. Augmentation typically includes incorporating additional medications with the primary drug with the goal of boosting the therapeutic efficacy of the primary drug. Typically, these additional medications have different mechanisms of action. However, there are no large-scale randomized controlled trials (RCTs) to inform treatment augmentation after first-line treatments for OCD produce suboptimal outcomes. The available evidence is predominantly based on small-scale RCTs, open-label trials, and case series.

In this article, we review the evidence for treatment augmentation strategies for OCD and summarize 8 studies that show promising results (Table^10-17). We focus only on pharmacologic agents and do not include other biological interventions, such as repetitive transcranial magnetic stimulation over supplementary motor area, ablative neurosurgery, or deep brain stimulation.

Numerous studies support the role of glutamate dysregulation in the pathophysiology of OCD. Cortico-striato-thalamo-cortical (CSTC) abnormalities play a major role in the pathophysiology of OCD as suggested by neuroimaging research studies that indicate glutamate is the fundamental neurotransmitter of the CSTC circuit. Dysregulation of glutamatergic signaling within this circuit has been linked to OCD. Patients with OCD have been found to have an increase of glutamate in the CSF. As a result, medications that affect glutamate levels can be used to treat patients with OCD who do not respond to first-line agents. In patients already taking SRIs, augmentation of glutamate-modulating medications can reduce OCD symptoms. As an uncompetitive antagonist of the N-methyl-d-aspartate (NMDA)-type glutamate receptor, amantadine has been proposed as 1 of these medications.

Naderi et al¹⁰ evaluated amantadine as augmentative therapy to fluvoxamine for treating patients with moderate to severe OCD.

Study design

• This 12-week, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of amantadine as an augmentative agent to fluvoxamine in 106 patients age 18 to 60 with moderate to severe OCD.
• Participants met DSM-5 criteria for OCD and had a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score >21. Participants were excluded if they had any substance dependence; an IQ <70; any other Axis I mental disorder; any serious cardiac, renal, or hepatic disease; had received psychotropic medications during the last 6 weeks, were pregnant or breastfeeding, or had rising liver transaminases to 3 times the upper limit of normal or higher.
• Participants received fluvoxamine 100 mg twice daily plus amantadine 100 mg/d, or fluvoxamine 100 mg twice daily plus placebo. All patients received fluvoxamine 100 mg/d for 28 days followed by 200 mg/d for the remainder of the trial.
• The primary outcome measure was difference in Y-BOCS total scores between the amantadine and placebo groups. The secondary outcome was the difference in Y-BOCS obsession and compulsion subscale scores.

Outcomes

• Patients who received amantadine augmentation experienced a significant reduction in Y-BOCS total score (P < .001) and obsession subscale score (P < .01).
• The amantadine group showed good tolerability and safety. There were no clinically significant adverse effects.

• Amantadine is an effective adjuvant to fluvoxamine for reducing OCD symptoms.

Conclusion

• Ondansetron and granisetron can be beneficial as an augmentation strategy for patients with treatment-resistant OCD.

2. Sharafkhah M, Aghakarim Alamdar M, Massoudifar A, et al. Comparing the efficacy of ondansetron and granisetron augmentation in treatment-resistant obsessive-compulsive disorder: a randomized double-blind placebo-controlled study. Int Clin Psychopharmacol. 2019;34(5):222- 233. doi:10.1097/YIC.0000000000000267

Although selective serotonin reuptake inhibitors (SSRIs) are considered a first-line treatment when teamed with CBT and antipsychotic augmentation, symptom resolution is not always achieved, and treatment resistance is a common problem. Sharafkhah et al¹¹ compared the efficacy of ondansetron and granisetron augmentation specifically for patients with treatment-resistant OCD.

Study Design

• In this 18-week, randomized, double-blind, placebo-controlled study, 135 patients with treatment-resistant OCD who were previously treated with a combination of an SSRI and an antipsychotic received augmentation with ondansetron (n = 45, 4 mg/d), granisetron (n = 45, 2 mg/d), or placebo.
• Patients were rated using Y-BOCS every 2 weeks during phase I (intervention period), which lasted 14 weeks. After completing the intervention, patients were followed for 4 more weeks during phase II (discontinuation period).
• The aim of this study was to determine the safety, efficacy, and tolerability of ondansetron vs granisetron as augmentation for patients with treatment-resistant OCD. A secondary aim was to determine the rate of relapse of OCD symptoms after discontinuing ondansetron as compared with granisetron at 4 weeks after intervention.

Outcomes

• At Week 14, the reductions in Y-BOCS scores in the ondansetron, granisetron, and placebo groups were 41.5%, 39.7%, and 15.2%, respectively (P = .001). The reduction in Y-BOCS score in the ondansetron and granisetron groups was significantly greater than placebo at all phase I visits.
• Complete response was higher in the ondansetron group compared with the granisetron group (P = .041).
• Y-BOCS scores increased in both the ondansetron and granisetron groups during the discontinuation phase, but OCD symptoms were not significantly exacerbated.

Conclusion

• Ondansetron and granisetron can be beneficial as an augmentation strategy for patients with treatment-resistant OCD.

Increased glutamate levels in CSF, glutamatergic overactivity, and polymorphisms of genes coding the NMDA receptor have been shown to contribute to the occurrence of OCD. Memantine is a noncompetitive antagonist of the NMDA receptor. Various control trials have shown augmentation with memantine 5 mg/d to 20 mg/d significantly reduced symptom severity in patients with moderate to severe OCD. Modarresi et al¹² evaluated memantine as a treatment option for patients with severe OCD who did not respond to SRI monotherapy.

Study design

• This 12-week, double-blind, randomized, placebo-controlled trial evaluated the efficacy of memantine augmentation in 32 patients age 18 to 40 who met DSM-5 criteria for OCD, had a Y-BOCS score ≥24, and no psychiatric comorbidity. Participants had not responded to ≥3 adequate trials (minimum 3 months) of SRI therapy, 1 of which was clomipramine.
• Individuals were excluded if they were undergoing CBT; had an additional anxiety disorder, mood disorder, or current drug or alcohol use disorder, or any systemic disorder; had a history of seizures; were pregnant or breastfeeding; or had a history of memantine use.
• Participants already receiving the maximum tolerated dose of an SRI received augmentation with memantine 20 mg/d or placebo.
• The primary outcome measure was change in Y-BOCS score from baseline. The secondary outcome was the number of individuals who achieved treatment response (defined as ≥35% reduction in Y-BOCS score).

Continue to: Outcomes...

Outcomes

• There was a statistically significant difference in Y-BOCS score in patients treated with memantine at Week 8 and Week 12 vs those who received placebo. By Week 8, 17.2% of patients in the memantine group showed a decrease in Y-BOCS score, compared with -0.8% patients in the placebo group. The difference became more significant by Week 12, with 40.9% in the memantine group showing a decrease in Y-BOCS score vs -0.3% in the placebo group. This resulted in 73.3% of patients achieving treatment response.
• Eight weeks of memantine augmentation was necessary to observe a significant improvement in OCD symptoms, and 12 weeks was needed for treatment response.
• The mean Y-BOCS total score decreased significantly in the memantine group from Week 4 to Week 8 (16.8%) and again from Week 8 to Week 12 (28.5%).
• The memantine group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• Memantine augmentation in patients with severe OCD who do not respond to an SRI is effective and well-tolerated.

• Biweekly assessments consisted of scores on the Y-BOCS, Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Rating Scale (HAM-A).
• The primary outcomes were improvement in Y-BOCS score and the clinical response rate. Secondary outcomes included a change in score on the Y-BOCS subscales, HARS, and HAM-A. Data were analyzed with the intention-to-treat sample.

Outcomes

• Forty-one patients finished the trial. The baseline Y-BOCS total scores and subscale scores did not differ significantly between the 2 groups.
• Improvements in Y-BOCS total score and obsession subscale score were more prominent in the fluvoxamine plus MPH-ER group compared with the placebo group (P < .001).
• HDRS score decreased in both the placebo and MPH-ER groups. HAM-A scores decreased significantly in the MPH-ER plus fluvoxamine group compared with the placebo group.

Conclusion

• This study demonstrated that the combination of fluvoxamine and MPH-ER produces a higher and faster response rate than fluvoxamine plus placebo in patients with OCD.

Glutamate dysregulation is implicated in the pathogenesis of OCD. Glutamate-modulating agents have been used to treat OCD. Studies have shown L-carnosine has a neuroprotective role via its modulatory effect on glutamate. Arabzadeh et al¹⁷ evaluated the efficacy of L-carnosine as an adjuvant to fluvoxamine for treating OCD.

Study design

• This 10-week, randomized, double-blind, placebo-controlled trial evaluated the efficacy of adjunctive L-carnosine in 40 patients age 18 to 60 who met DSM-5 criteria for OCD and had moderate to severe OCD (Y-BOCS score ≥21).
• Individuals with any other DSM-5 major psychiatric disorders, serious medical or neurologic illness, substance dependence (other than caffeine or nicotine), mental retardation (based on clinical judgment), were pregnant or breastfeeding, had any contraindication for the use of L‐carnosine or fluvoxamine, or received any psychotropic drugs in the previous 6 weeks were excluded.
• Participants received fluvoxamine 100 mg/d for the first 4 weeks and 200 mg/d for the next 6 weeks plus either L-carnosine 500 mg twice daily or placebo. This dosage of L-carnosine was chosen because previously it had been tolerated and effective.
• The primary outcome measure was difference in Y-BOCS total scores. Secondary outcomes were differences in Y-BOCS obsession and compulsion subscale scores and differences in change in score on Y-BOCS total and subscale scores from baseline.

Outcomes

• The L-carnosine group experienced a significant decrease in Y-BOCS total score (P < .001), obsession subscale score (P < .01), and compulsion subscale score (P < .01).
• The group that received fluvoxamine plus L-carnosine also experienced a more complete response (P = .03).
• The L-carnosine group showed good tolerability and safety. There were no clinically significant adverse effects.

Conclusion

• L-carnosine significantly reduces OCD symptoms when used as an adjuvant to fluvoxamine.

CASE Fixated on health and nutrition

At the insistence of her daughter, Ms. L, age 75, presents to the emergency department (ED) for self-neglect and severe weight loss, with a body mass index (BMI) of 13.5 kg/m² (normal: 18.5 to 24.9 kg/m²). When asked why she is in the ED, Ms. L says she doesn’t know. She attributes her significant weight loss (approximately 20 pounds in the last few months) to gastroesophageal reflux disease (GERD). She constantly worries about her esophagus. She had been diagnosed with esophageal dysphagia 7 years ago after undergoing radiofrequency ablation for esophageal cancer. Ms. L fixates on the negative effects certain foods and ingredients might have on her stomach and esophagus.

Following transfer from the ED, Ms. L is involuntarily admitted to our inpatient unit. Although she acknowledges weight loss, she minimizes the severity of her illness and indicates she would like to gain weight, but only by eating healthy foods she is comfortable with, including kale, quinoa, and vegetables. Ms. L says that she has always been interested in “healthful foods” and that she “loves sugar,” but “it’s bad for you,” mentioning that “sugar fuels cancer.” She has daily thoughts about sugar causing cancer. Ms. L also mentions that she stopped eating flour, sugar, fried food, and oils because those foods affect her “stomach acid” and cause “pimples on my face and weight loss.” While in the inpatient unit, Ms. L requests a special diet and demands to know the origin and ingredients of the foods she is offered. She emphasizes that her esophageal cancer diagnosis and dysphagia exacerbate worries that certain foods cause cancer, and wants to continue her diet restrictions. Nonetheless, she says she wants to get healthy, and denies an intense fear of gaining weight or feeling fat.

HISTORY Multiple psychiatric diagnoses

Ms. L lives alone and enjoys spending time with her grandchildren, visiting museums, and listening to classical music. However, her family, social workers, and records from a previous psychiatric hospitalization reveal that Ms. L has a history of psychiatric illness and fears regarding certain types of foods for much of her adult life. Ms. L’s family also described a range of compulsive behaviors, including shoplifting, hoarding art, multiple plastic surgeries, and phases where Ms. L ate only frozen yogurt without sugar.

Ms. L’s daughter reported that Ms. L had seen a psychologist in the late 1990s for depression and had been diagnosed with obsessive-compulsive disorder (OCD) and attention deficit/hyperactivity disorder in the early 2000s. In 2006, during a depressive episode after her divorce, Ms. L had a suicide attempt with pills and alcohol, and was hospitalized. Records from that stay described a history of mood dysregulation with fears regarding food and nutrition. Ms. L was treated with aripiprazole 5 mg/d. A trial of trazodone 25 mg/d did not have any effect. When discharged, she was receiving lamotrigine 100 mg/d. However, her daughter believes she stopped taking all psychiatric medications shortly after discharge.

Her daughter says that in the past 2 years, Ms. L has seen multiple doctors for treatment of somatic gastrointestinal (GI) complaints. A 2018 note from a social worker indicated that Ms. L endorsed taking >80 supplements per day and constantly researched nutrition online. In the months leading to her current hospitalization, Ms. L suffered from severe self-neglect and fear regarding foods she felt were not healthy for her. She had stopped leaving her apartment.

EVALUATION Poor insight, normal lab results

During her evaluation, Ms. L appears cachectic and frail. She has a heavily constricted affect and is guarded, dismissive, and vague. Although her thought processes are linear and goal-directed, her insight into her condition is extremely poor and she appears surprised when clinicians inform her that her self-neglect would lead to death. Instead, Ms. L insists she is eating healthily and demonstrates severe anxiety in relation to her GI symptoms.

Ms. L is oriented to person, place, and time. She scores 27/30 on the Montreal Cognitive Assessment, indicating normal cognition. She denies any depressive symptoms or suicidal intent. She does not appear to be internally preoccupied and denies having auditory or visual hallucinations or manic symptoms.

A neurologic examination reveals that her cranial nerves are normal, and cerebellar function, strength, and sensory testing are intact. Her gait is steady and she walks without a walker. Despite her severely low BMI and recent history of self-neglect, Ms. L’s laboratory results are remarkably normal and show no liver, metabolic, or electrolyte abnormalities, no signs of infection, and normal vitamin B12 levels. She has slightly elevated creatinine and blood urea nitrogen levels, but a normal glomerular filtration rate.

Her medical history is significant for squamous cell esophageal cancer, treated with radiofrequency ablation. Although Ms. L is constantly worried about the recurrence of cancer, pathology reports demonstrate no esophageal dysplasia. However, she does show evidence of an approximately 1 cm × 1 cm mild, noncircumferential esophageal stenosis, likely resulting from radio­frequency ablation.

The authors’ observations

Several health- and physical symptom-related psychiatric disorders have overlapping features, which can complicate the differential diagnosis (Table 1¹). Ms. L presented to the ED with a severely low BMI of 13.5 kg/m², obsessions regarding specific types of food, and preoccupations regarding her esophagus. Despite her extensive psychiatric history (including intense fears regarding food), we ruled out a primary psychotic disorder because she did not describe auditory or visual hallucinations and never appeared internally preoccupied. While her BMI and persistent minimization of the extent of her disease meet criteria for anorexia nervosa, she denied body dysmorphia and did not have any fear of gaining weight.

A central element of Ms. L’s presentation was her anxiety regarding how certain types of foods impact her health as well as her anxieties regarding her esophagus. While Ms. L was in remission from esophageal cancer and had a diagnosis of esophageal dysphagia, these preoccupations and obsessions regarding how certain types of foods affect her esophagus drove her to self-neglect and thus represent pathologic thought processes out of proportion to her symptoms. Illness anxiety disorder was considered because Ms. L met many of its criteria: preoccupation with having a serious illness, disproportionate preoccupation with somatic symptoms if they are present, extreme anxiety over health, and performance of health-related behaviors.¹ However, illness anxiety disorder is a diagnosis of exclusion, and 1 criterion is that these symptoms cannot be explained by another mental disorder. We felt other diagnoses better fit Ms. L’s condition and ruled out illness anxiety disorder.

Ms. L’s long history of food and non-food–related obsessions and compulsions that interrupted her ability to perform daily activities were strongly suggestive for OCD. Additionally, her intense preoccupation, high level of anxiety, amount of time and energy spent seeking care for her esophagus and GERD symptoms, and the resulting significant disruption of daily life, met criteria for somatic symptom disorder (SSD). However, we did not believe that a diagnosis of OCD and SSD alone explained the entirety of Ms. L’s clinical picture. Despite ruling out anorexia nervosa, Ms. L nonetheless demonstrated disordered eating.

Avoidant/restrictive food intake disorder (ARFID) is an eating disorder in which patients restrict their diet and do not meet nutritional needs for any number of reasons, do not experience body dysmorphia, and do not fear weight gain.¹ A common feature of ARFID is a fear of negative consequences from eating specific types of food.² Table 2^1,2 summarizes additional clinical features of ARFID. Although ARFID is typically diagnosed in children and adolescents, particularly in individuals with autism with heightened sensory sensitivities, ARFID is also common among adult patients with GI disorders.³ In a retrospective chart review of 410 adults ages 18 to 90 (73% women) referred to a neurogastroenterology care center, 6.3% met the full criteria for ARFID and 17.3% had clinically significant avoidant or restrictive eating behaviors. Among patients with ARFID symptoms, 93% stated that a fear of GI symptoms was the driver of their avoidant or restrictive eating behaviors.² Patients with GI diseases often develop dietary control and avoidance coping mechanisms to alleviate their symptoms.⁴ These strategies can exacerbate health anxieties and have a detrimental effect on mental health.⁵ Patients with GI disorders have a high degree of comorbidity with affective disorders, including anxiety disorders.⁶ These trends may arise from hypervigilance and the need to gain control over physical symptoms.⁷ Feeling a need for control, actions driven by anxiety and fear, and the need for compensatory behaviors are cardinal features of OCD and eating disorders.⁸ Multiple studies have demonstrated comorbidities between irritable bowel syndrome and eating disorders,⁹ SSD,¹⁰ and OCD.¹¹ Taken together with observations that ARFID is also found in patients with GI disorders,² these findings demonstrate that patients with a history of GI disease are at high risk of developing extreme health anxieties and behavioral coping strategies that can lead to disordered eating.

The rise in “healthy” eating materials online—particularly on social media—has created an atmosphere in which misinformation regarding diet and health is common and widespread. For patients with OCD and a predisposition to health anxiety, such as Ms. L, searching online for nutrition information and healthy living habits can exacerbate food-related anxieties and can lead to a pathological drive for purity and health.¹²Although not included in DSM-5, orthorexia nervosa was identified in 1997 as a proposed eating disorder best characterized as an obsession with healthy eating with associated restrictive behaviors.¹³ Patients with this disorder are rarely focused on losing weight, and orthorexic eating behaviors have been associated with both SSD and OCD.^12,14 As in Ms. L’s case, patients with orthorexia nervosa demonstrate intrusive obsessions with nutrition, spend excessive amount of time researching nutrition, and fixate on food quality.¹² Throughout Ms. L’s hospitalization, even as her food-related magical thinking symptoms improved, she constantly informed her care team that she had been “eating healthily” even though she was severely cachectic. Patients with SSD and OCD prone to health anxieties are at risk of developing pathologic food beliefs and dangerous eating behaviors. These patients may benefit from psychoeducation regarding nutrition and media literacy, which are components of effective eating disorder programs.¹⁵

The authors’ observations

How do we approach the pharmacologic treatment of patients with co-occurring eating, somatic symptom, and anxiety disorders? Olanzapine facilitates recovery in children and adolescents with ARFID by promoting eating and weight gain, and decreasing symptoms of depression and anxiety.¹⁶ Patients with orthorexia nervosa also may benefit from treatment with olanzapine, which has decreased food-related fixations, magical thinking, and delusions regarding food.¹⁷ Further, orthorexic patients with ARFID have also been shown to respond to SSRIs due to those agents’ efficacy for treating intrusive thoughts, obsessions, and preoccupations from OCD and SSD.^18,19 Thus, treating Ms. L’s symptoms with olanzapine and fluoxetine targeted the intersection of several diagnoses on our differential. Olanzapine’s propensity to cause weight gain is favorable in this population, particularly patients such as Ms. L, who do not exhibit body dysmorphia or fear of gaining weight.

OUTCOME Weight gain and fewer fears

Ms. L is prescribed olanzapine 5 mg/d and fluoxetine 20 mg/d. She gains 20.6 pounds in 4 weeks. Importantly, she endorses fewer fears related to foods and expands her palate to include foods she previously considered to be unhealthy, including white bread and farm-raised salmon. Further, she spends less time thinking about food and says she has less anxiety regarding the recurrence of GI symptoms.

Among patients with ARFID symptoms, 93% stated that a fear of GI symptoms was the driver of their avoidant or restrictive eating behaviors.² Patients with GI diseases often develop dietary control and avoidance coping mechanisms to alleviate their symptoms.⁴ These strategies can exacerbate health anxieties and have a detrimental effect on mental health.⁵ Patients with GI disorders have a high degree of comorbidity with affective disorders, including anxiety disorders.⁶ These trends may arise from hypervigilance and the need to gain control over physical symptoms.⁷ Feeling a need for control, actions driven by anxiety and fear, and the need for compensatory behaviors are cardinal features of OCD and eating disorders.⁸ Multiple studies have demonstrated comorbidities between irritable bowel syndrome and eating disorders,⁹ SSD,¹⁰ and OCD.¹¹ Taken together with observations that ARFID is also found in patients with GI disorders,² these findings demonstrate that patients with a history of GI disease are at high risk of developing extreme health anxieties and behavioral coping strategies that can lead to disordered eating.

The rise in “healthy” eating materials online—particularly on social media—has created an atmosphere in which misinformation regarding diet and health is common and widespread. For patients with OCD and a predisposition to health anxiety, such as Ms. L, searching online for nutrition information and healthy living habits can exacerbate food-related anxieties and can lead to a pathological drive for purity and health.¹²Although not included in DSM-5, orthorexia nervosa was identified in 1997 as a proposed eating disorder best characterized as an obsession with healthy eating with associated restrictive behaviors.¹³ Patients with this disorder are rarely focused on losing weight, and orthorexic eating behaviors have been associated with both SSD and OCD.^12,14 As in Ms. L’s case, patients with orthorexia nervosa demonstrate intrusive obsessions with nutrition, spend excessive amount of time researching nutrition, and fixate on food quality.¹² Throughout Ms. L’s hospitalization, even as her food-related magical thinking symptoms improved, she constantly informed her care team that she had been “eating healthily” even though she was severely cachectic. Patients with SSD and OCD prone to health anxieties are at risk of developing pathologic food beliefs and dangerous eating behaviors. These patients may benefit from psychoeducation regarding nutrition and media literacy, which are components of effective eating disorder programs.¹⁵

The authors’ observations

How do we approach the pharmacologic treatment of patients with co-occurring eating, somatic symptom, and anxiety disorders? Olanzapine facilitates recovery in children and adolescents with ARFID by promoting eating and weight gain, and decreasing symptoms of depression and anxiety.¹⁶ Patients with orthorexia nervosa also may benefit from treatment with olanzapine, which has decreased food-related fixations, magical thinking, and delusions regarding food.¹⁷ Further, orthorexic patients with ARFID have also been shown to respond to SSRIs due to those agents’ efficacy for treating intrusive thoughts, obsessions, and preoccupations from OCD and SSD.^18,19 Thus, treating Ms. L’s symptoms with olanzapine and fluoxetine targeted the intersection of several diagnoses on our differential. Olanzapine’s propensity to cause weight gain is favorable in this population, particularly patients such as Ms. L, who do not exhibit body dysmorphia or fear of gaining weight.

OUTCOME Weight gain and fewer fears

Ms. L is prescribed olanzapine 5 mg/d and fluoxetine 20 mg/d. She gains 20.6 pounds in 4 weeks. Importantly, she endorses fewer fears related to foods and expands her palate to include foods she previously considered to be unhealthy, including white bread and farm-raised salmon. Further, she spends less time thinking about food and says she has less anxiety regarding the recurrence of GI symptoms.

Evidence-based cognitive-behavioral therapies for posttraumatic stress disorder (PTSD) may employ cognitive restructuring. This psychotherapeutic technique entails recognizing and correcting maladaptive, inaccurate thoughts that perpetuate illness.¹ For example, a clinician helps a patient recognize that the negative thought “Nobody loves me” following a romantic breakup is an overgeneralization. The patient is taught to self-correct this to “While my ex-girlfriend doesn’t love me, others do. It only feels like nobody loves me.”²

We introduce the acronym I STEP to help clinicians recognize several common distorted thoughts in PTSD. These tend to occur within stereotyped themes in PTSD,³ as outlined and illustrated below. Recognizing distorted thoughts in these patients will help clinicians understand and address psychological distress following trauma.

Intimacy/In-touch. Intimacy involves comfort in relationships, including but not limited to sexual intimacy. This requires being in touch emotionally with self and others. In trauma involving loss, fear of further loss may impair intimacy with others. Difficulty with self-intimacy impairs commitment to life’s goals and prompts unhelpful avoidance behaviors, such as difficulty being alone or self-injurious use of drugs or alcohol. Comfort in spending some portion of time alone with one’s thoughts and emotions is a life skill necessary to attain optimum function. Patients who are unable to tolerate their own emotions without constant company might have excessive anxiety when social supports are otherwise occupied. Such patients might seek excessive and repeated reassurance rather than learning to tolerate their own emotions and thoughts. They would then find it difficult to engage successfully in solo activities.

Safety. After trauma, patients may view themselves and others as unsafe, and may overestimate risk. For example, a pedestrian who is struck by a vehicle may believe that crossing a street will again result in getting hit by a car without appreciating that people frequently cross streets without injury or that crossing cautiously is an essential life skill. Parents who have suffered from trauma may unduly believe that their children are in danger when engaging in an activity generally considered to be safe. This may create challenges in parenting and impede their children’s ability to develop a sense of independence.

Trust. Trauma victims may unfairly blame themselves, leading them to mistrust their own judgment. Such patients may have difficulty making decisions confidently and independently, such as choosing a job or a romantic partner. When traumatized by another person or people, it can be difficult to maintain positive views of others or to accept others’ positive behaviors as genuine. For example, a common reaction following rape may be a generalized mistrust of all men.

Esteem. Patients’ self-esteem may suffer following trauma due to irrational self-blame or believing the “just world hypothesis”—the idea that bad things only happen to bad people. For example, a patient who suffers an assault by an acquaintance might think “I must be stupid if I couldn’t figure out that my friend was dangerous.”

Power. Traumatic events usually occur outside of one’s control. Survivors of trauma may lose confidence in their ability to control any aspect of their lives. Conversely, they may attempt to gain control of all of life’s circumstances, including those that are beyond anyone’s control. Control can be applied to emotions, behaviors, or events. A driver struck by a vehicle may think “I can’t control other drivers, so I have no power to control my safety while driving,” and hence give up driving. While there are things that are beyond our control, this extreme thought ignores things that we can control, such as wearing seatbelts or having the vehicle’s brakes regularly serviced.

With the COVID-19 pandemic turning the world on its head, we have seen more first-episode psychotic breaks and quick deterioration in previously stable patients. Early in the pandemic, care was particularly complicated for psychiatric patients who had been infected with the virus. Many of these patients required immediate psychiatric hospitalization. At that time, many community hospital psychiatric inpatient units did not have the capacity, staffing, or infrastructure to safely admit such patients, so they needed to be managed on a medical unit. Here, I discuss the case of a COVID-19–positive woman with psychiatric illness who we managed while she was in quarantine on a medical unit.

Case report

Early in the COVID-19 pandemic, Ms. B, a 35-year-old teacher with a history of depression, was evaluated in the emergency department for bizarre behavior and paranoid delusions regarding her family. Initial laboratory and imaging testing was negative for any potential medical causes of her psychiatric symptoms. Psychiatric hospitalization was recommended, but before Ms. B could be transferred to the psychiatric unit, she tested positive for COVID-19. At that time, our community hospital did not have a designated wing on our psychiatric unit for patients infected with COVID-19. Thus, Ms. B was admitted to the medical floor, where she was quarantined in her room. She would need to remain asymptomatic and test negative for COVID-19 before she could be transferred to the psychiatric unit.

Upon arriving at the medical unit, Ms. B was hostile and uncooperative. She frequently attempted to leave her room and required restraints throughout the day. Our consultation-liaison (CL) team was consulted to assist in managing her. During the initial interview, we noticed that she had covered all 4 walls of her room with papers filled with handwritten notes. Ms. B had cut her gown to expose her stomach and legs. She had pressured speech, tangential thinking, and was religiously preoccupied. She denied any visual and auditory hallucinations, but her persecutory delusions involving her family persisted. We believed that her signs and symptoms were consistent with a manic episode from underlying, and likely undiagnosed, bipolar I disorder that was precipitated by her COVID-19 infection.

We first addressed Ms. B’s and the staff’s safety by transferring her to a larger room with a vestibule at the end of the hallway so she had more room to walk and minimal exposure to the stimuli of the medical unit. We initiated one-on-one observation to redirect her and prevent elopement. We incentivized her cooperation with staff by providing her with paper, pencils, reading material, and phone privileges. We started oral risperidone 2 mg twice daily and lorazepam 2 mg 3 times daily for short-term behavioral control and acute treatment of her symptoms, with the goal of deferring additional treatment decisions to the inpatient psychiatry team after she was transferred to the psychiatric unit. Ms. B’s agitation and impulsivity improved. She began participating with the medical team and was eventually transferred out of our medical unit to a psychiatric unit at a different facility.

COVID-19 and psychiatric illness: Clinical concerns

While infection from COVID-19 and widespread social distancing of the general population have been linked to depression and anxiety, manic and psychotic symptoms secondary to the COVID-19 pandemic have not been well described. The association between influenza infection and psychosis has been reported since the Spanish Flu pandemic,¹ but there is limited data on the association between COVID-19 and psychosis. A review of 14 studies found that 0.9% to 4% of people exposed to a virus during an epidemic or pandemic develop psychosis or psychotic symptoms.¹ Psychosis was associated with viral exposure, treatments used to manage the infection (steroid therapy), and psychosocial stress. This study also found that treatment with low doses of antipsychotic medication—notably aripiprazole—seemed to have been effective.¹

Nonetheless, it is important to keep in mind a thorough differential diagnosis and rule out any potential organic etiologies in a COVID-19–positive patient who presents with psychiatric symptoms.² For Ms. B, we began by ruling out drug-induced psychosis and electrolyte imbalance, and obtained brain imaging to rule out malignancy. We considered an interictal behavior syndrome of temporal lobe epilepsy, a neuropsychiatric disorder characterized by alterations in sexual behavior, religiosity, and extensive and compulsive writing and drawing.³ Neurology was consulted to evaluate the patient and possibly use EEG to detect interictal spikes, a tall task given the patient’s restlessness and paranoia. Ultimately, we determined the patient was most likely exhibiting symptoms of previously undetected bipolar disorder.

Managing patients with psychiatric illness on a medical floor during a pandemic such as COVID-19 requires the psychiatrist to truly serve as a consultant and liaison between the patient and the treatment team.⁴ Clinical management should address both infection control and psychiatric symptoms.⁵ We visited with Ms. B frequently, provided psychoeducation, engaged her in treatment, and updated her on the treatment plan.

As the medical world continues to adjust to treating patients during the pandemic, CL psychiatrists may be tasked with managing patients with acute psychiatric illness on the medical unit while they await transfer to a psychiatric unit. A creative, multifaceted, and team-based approach is key to ensure effective care and safety for all involved.

In this month’s issue of GI & Hepatology News, we celebrate the recently named recipients of this year’s AGA Recognition Prizes, several of whom I am privileged to work with on a daily basis. We also welcome the newest members of AGA’s Governing Board, Maria T. Abreu, MD, AGAF, who is an outstanding leader and representative of a much larger group of volunteer members who work tirelessly to advance AGA’s initiatives to enhance the clinical practice of gastroenterology and improve patient outcomes. The nominating committee also appointed the following slate of councilors, which is subject to membership vote: Kim Barrett, PhD, AGAF; Lawrence Kosinski, MD, MBA, AGAF; and Sheryl Pfeil, MD, AGAF.

This month’s issue also highlights two newly-developed clinical risk-prediction tools – one designed to assist clinicians in predicting alcoholic hepatitis mortality, and another designed to identify inflammatory bowel disease (IBD) patients at high-risk of developing venous thromboembolism (VTE) post-hospitalization. While no prediction model is perfect, these tools can positively impact clinical decision-making and contribute to improved patient outcomes. We also include recommendations on managing IBD in older patients, and report on a study suggesting an increase in late-stage cancer diagnoses in the wake of the COVID-19 pandemic. AGA’s new clinical guideline on systemic therapy for hepatocellular carcinoma and Clinical Practice Update on non-invasive colorectal cancer screening also are featured. Finally, in this month’s Practice Management Toolbox, Dr. Feuerstein, Dr. Sofia, Dr. Guha, and Dr. Streett offer timely recommendations regarding how to overcome existing barriers to achieve high-value IBD care.

On February 22, the US Preventive Services Task Force (USPSTF) posted draft recommendations on the use of statins as a method of primary prevention of cardiovascular disease (CVD).¹ This is an update to their 2016 recommendations and reaffirms the guidance published at that time.

What’s recommended. The recommendations have 3 parts and are intended for adults with no evidence or previous diagnosis of CVD.

• Statins should be prescribed for those who meet 3 criteria: (1) are ages 40 through 75 years; (2) have 1 or more CVD risk factors (high blood pressure, dyslipidemia, diabetes, tobacco use); and (3) have a calculated 10-year risk of a CVD event of 10% or greater. (The American College of Cardiology/American Heart Association ASCVD Risk Calculator, recommended by the USPSTF, can be found at www.cvriskcalculator.com/.) This is a “B” recommendation.¹
• Selectively offer a statin, based on a discussion of benefits and risks and patient preferences, to those who meet criteria 1 and 2 above but who have a calculated CVD risk of 7.5% to 10%. This is a “C” recommendation.¹
• For those ages 76 years and older, there is insufficient evidence to assess benefits and harms of statin use. The USPSTF therefore issued an “I” statement for this group.¹

What to prescribe. The USPSTF feels that moderate-intensity statin therapy is a reasonable approach for most people who use statins for primary CVD prevention. This would equate to atorvastatin 10 mg, pravastatin 40 mg, or simvastatin 20 to 40 mg daily.¹

A few notes on the evidence. Data from 22 studies were included in the evidence review upon which the recommendations are based. The mean duration of follow-up was 3 years. The number needed to treat to prevent 1 stroke was about 256; to prevent 1 myocardial infarction, 112; and to prevent all CVD events, 78.²

What others recommend. These recommendations are mostly consistent with those of the American College of Cardiology and the American Heart Association, except that those organizations recommend initiating statins in all those with a 10-year CVD risk ≥ 7.5%.¹

On February 22, the US Preventive Services Task Force (USPSTF) posted draft recommendations on the use of statins as a method of primary prevention of cardiovascular disease (CVD).¹ This is an update to their 2016 recommendations and reaffirms the guidance published at that time.

What’s recommended. The recommendations have 3 parts and are intended for adults with no evidence or previous diagnosis of CVD.

• Statins should be prescribed for those who meet 3 criteria: (1) are ages 40 through 75 years; (2) have 1 or more CVD risk factors (high blood pressure, dyslipidemia, diabetes, tobacco use); and (3) have a calculated 10-year risk of a CVD event of 10% or greater. (The American College of Cardiology/American Heart Association ASCVD Risk Calculator, recommended by the USPSTF, can be found at www.cvriskcalculator.com/.) This is a “B” recommendation.¹

What is your approach to differentiating EPI from other pancreatic conditions when making a diagnosis?

Dr. Kothari: Exocrine pancreatic insufficiency, or EPI, is a condition largely defined by malabsorption as the result of inadequate digestive enzymes. The resulting symptoms from maldigestion include bloating, malodorous gas, abdominal pain, changes in bowel habits, and weight change. EPI can be caused by intrinsic pancreatic disorders (such as chronic pancreatitis, acute pancreatitis, cystic fibrosis or pancreatic cancer) or from extra-pancreatic diseases (including the result of gastrointestinal surgery). Thus, EPI should be considered a consequence of an already existing gastrointestinal disorder.

Can you a speak a little bit more about the signs and symptoms or characteristics that are most common in patients with EPI?

Dr. Kothari: The symptoms of EPI can range from bloating and abdominal pain with mild to overt steatorrhea with greasy and oily stools that are difficult to flush with malodorous flatulence, weight loss, and symptoms of vitamin and micronutrient deficiency. The pathophysiology of these symptoms results from inadequate enzymes which are needed for digestion. Particularly, lipase is the major enzyme needed for fat digestion and thus when not present leads to fat maldigestion resulting in symptoms. Furthermore, undigested fats result in alterations in gut motility which can further exacerbate symptoms to include nausea, vomiting, early satiety and inadequate stool evacuation.

Patients who have fat malabsorption, particularly for pancreatic insufficiency, can also have malnutrition as a result of inadequate absorption of nutrients and micronutrients. Particularly, we think about fat-soluble vitamins-- vitamin A, vitamin E, vitamin D, and vitamin K and in the initial evaluation of patients with established EPI, one could consider evaluation of comorbid bone disease.

How crucial is having the correct interpretation of the clinical presentation to pinpointing the diagnosis?

Dr. Kothari: This is a great question because, with exocrine pancreatic insufficiency as there is growing publicity for the disorder and because symptoms can be rather non-specific when mild, it is important to be informed on how best to make this diagnosis. Thus, it is important to review the predisposing conditions that may lead to the diagnosis of EPI. These conditions include cystic fibrosis, chronic pancreatitis, acute pancreatitis, previous pancreatic surgery, history of pancreatic cancer (or suspicion for new pancreatic cancer), history of diabetes, celiac disease, history of luminal surgeries (including bariatric surgery), and inflammatory bowel disease. Further, since EPI can be a result of intrinsic pancreatic pathologies, it is critical to consider the risk factors for chronic pancreatitis which include alcohol and tobacco ingestion, prior episodes of recurrent acute pancreatitis, genetic conditions that may predispose patients to chronic pancreatitis, including cystic fibrosis, and hereditary conditions that also result in pancreatitis. As clinicians, it is our role to obtain an accurate history to best gauge the risk factors for EPI.

After reviewing risk factors, we then must review the clinical presentation to know if the symptoms could be from EPI which include bloating, gas, abdominal pain, weight changes, changes in bowel habits and consequences of vitamin deficiencies. Since the symptoms of mild EPI can be similar to other GI conditions such as SIBO, celiac disease, and functional bowel disorders, gauging whether a patient has risk factors for EPI will help the clinician understand how likely a diagnosis of EPI may be and if and what testing would be appropriate.

In my practice, I consider diagnostic testing in patients who may be at risk for EPI and have mild symptoms such malodorous gas, bloating and mild steatorrhea. For patient with clear evidence of steatorrhea (weight loss and vitamin deficiencies) and have strong risk factors for EPI (i.e. heavy alcohol and tobacco and/or a history of recurrent or severe acute pancreatitis), I might consider imaging and/or empiric therapies as to expedite care.

How difficult is it to diagnose EPI and what steps do you take to ensure that you prescribe patients with the proper therapy?

Dr. Kothari: The diagnosis of pancreatic insufficiency, in my mind, needs to start with assessing the pre-test probability of the patient having EPI, since testing could lead to a false positive.

The test of choice in most scenarios for diagnosing pancreatic insufficiency is a stool test known as the fecal elastase. It is a measurement of pancreatic elastase in the stool. The test itself is a concentration. For any condition that results in a dilute stool sample, that'll result in a falsely low value that can give a patient a false positive test. Now, this can be corrected  by the lab concentrating the stool sample before running the test, but that testing center needs to know how to do that.

The other assumption that we make with this stool test is that we assume that the elastase is a stable molecule that can traverse all the gut and be collected adequately. And for any reason, if that enzyme is degraded for any reason, it's also going to provide a low test, a low result, resulting in a false positive.

If they have risk factors for chronic pancreatitis or pancreatic disease and they're presenting with symptoms of EPI, then the usual test that I'll choose is dedicated pancreatic imaging such as an MRI or dedicated CT pancreatic imaging, or endoscopic ultrasound. If we clinch a diagnosis of chronic pancreatitis and they have symptoms of pancreatic insufficiency, I think that’s enough to presume a diagnosis of exocrine pancreatic insufficiency and start treatment.

On the other hand, in patients who do not have risk factors for pancreatic disease but there remains some clinical suspicion for exocrine pancreatic insufficiency, then it may be reasonable to check a fecal elastase to rule out pancreatic insufficiency. If the test results are low, then follow-up dedicated pancreas imaging would be the next step in delineating intrinsic pancreatic conditions form extra-pancreatic causes.  If pancreas imaging effectively rules out pancreatic disease then I consider checking for celiac disease, ruling out small intestinal bacterial overgrowth and considering assessment of luminal motility (either with a capsule or small bowel follow through). Although functional neuroendocrine tumors have been previously considered a cause of EPI, these tumors tend to present with secretory diarrhea which typically present differently (and often more dramatically) than other causes of EPI. Thus, I do not routinely check vasoactive hormone levels.

I think the American Gastroenterological Association has great patient education documents for our patients. Thus, I would encourage our colleagues to use the AGA for their resources for our patients on EPI.

The United States has never achieved a single high standard of medical care equity for all of its people, and the trend line does not appear favorable. The closest we have reached is basic Medicare (Parts A and B), military medicine, the Veterans Health Administration, and large nonprofit groups like Kaiser Permanente. It seems that the nature of we individualistic Americans is to always try to seek an advantage.

But even achieving equity in medical care would not ensure equity in health. The social determinants of health (income level, education, politics, government, geography, neighborhood, country of origin, language spoken, literacy, gender, and yes – race and ethnicity) have far more influence on health equity than does medical care.

Narratives can both reflect and influence culture. Considering the harmful effects of the current political divisiveness in the United States, the timing is ideal for our three leading medical and health education organizations – the American Medical Association, the Association of American Medical Colleges (AAMC), and the Centers for Disease Control and Prevention – to publish a definitive position paper called “Advancing Health Equity: A Guide to Language, Narrative and Concepts.”
 

What’s in a word?

According to William Shakespeare, “A rose by any other name would smell as sweet” (Romeo and Juliet). Maybe. But if the word used were “thorn” or “thistle,” it just would not be the same.

Words comprise language and wield enormous power with human beings. Wars are fought over geographic boundaries often defined by the language spoken by the people: think 2022, Russian-speaking Ukrainians. Think Winston Churchill’s massive 1,500-page “A History of the English-Speaking Peoples.” Think about the political power of French in Quebec, Canada.

Thus, it should be no surprise that words, acronyms, and abbreviations become rallying cries for political activists of all stripes: PC, January 6, Woke, 1619, BLM, Critical Race Theory, 1776, Remember Pearl Harbor, Remember the Alamo, the Civil War or the War Between the States, the War for Southern Independence, the War of Northern Aggression, the War of the Rebellion, or simply “The Lost Cause.” How about Realpolitik?

Is “medical language” the language of the people or of the profession? Physicians must understand each other, and physicians also must communicate clearly with patients using words that convey neutral meanings and don’t interfere with objective understanding. Medical editors prefer the brevity of one or a few words to clearly convey meaning.

Thus, it should be no surprise that words, acronyms, and abbreviations become rallying cries for political activists of all stripes: PC, January 6, Woke, 1619, BLM, Critical Race Theory, 1776, Remember Pearl Harbor, Remember the Alamo, the Civil War or the War Between the States, the War for Southern Independence, the War of Northern Aggression, the War of the Rebellion, or simply “The Lost Cause.” How about Realpolitik?

Is “medical language” the language of the people or of the profession? Physicians must understand each other, and physicians also must communicate clearly with patients using words that convey neutral meanings and don’t interfere with objective understanding. Medical editors prefer the brevity of one or a few words to clearly convey meaning.

Correct answer: B. Absence of ganglion cells on rectal biopsy. 
 
Rationale  
Hirschsprung's disease occurs in approximately 1 out of 5,000 live births and is caused by absence of ganglion cells in the myenteric plexus of the intestine. The condition arises from failure of the neural crest cells to fully migrate caudally along the intestine during early gestation, resulting in a distal portion of the intestine being aganglionic. Rectal and distal sigmoid involvement is seen in around 85% of cases, with the other 15 percent involving more proximal intestine. It can rarely involve the entire colon and small intestine. Ganglion cells inhibit local smooth muscles, resulting in the characteristic inability for aganglionic bowel to relax. This lack of inhibition gives rise to the absence of rectoanal inhibitory reflex (RAIRs) during anorectal manometry. The lack of inhibition also produces a transition zone on contrast enema, with the distal aganglionic bowel being narrow and the more proximal bowel containing ganglia being dilated. Lack of meconium passage in the first 48 hours of life raises concern for Hirschsprung's disease. Other causes for possible failure to pass meconium include cystic fibrosis, anorectal malformation, small left colon syndrome, meconium plug syndrome and megacystis-microcolon-intestinal hypoperistalsis syndrome.
