– Most physicians do not report adverse events related to noninvasive body contouring devices to the Food and Drug Administration, a database review showed.

“The FDA mandates that manufacturers and device operators disclose medical device reports to monitor suspected injuries and device malfunctions to the Manufacturer and User Facility Device Experience [MAUDE] database,” study author Adam J. Wulkan, MD, said at the annual conference of the American Society for Laser Medicine and Surgery. “Given the rapid growth in the noninvasive fat reduction market, it is essential physicians be aware of associated adverse events.”

Dr. Adam J. Wulkan
In what is believed to be the first study of its kind, Dr. Wulkan, a dermatologist at Massachusetts General Hospital, Boston, and his associates performed a search of complications of noninvasive fat reduction and cellulite reduction devices reported to the MAUDE database from January 2014 to October 2017. The search yielded 98 medical device reports (MDRs), most of which were submitted by patients.

“Given that this is the largest database for adverse events, I was surprised how few reports were done by physicians,” Dr. Wulkan said in an interview.

He reported results from 83 of the 98 MDRs. A total of 26 MDRs reported on cryolipolysis and included newly diagnosed or exacerbation of prior umbilical hernias (10), neuropathies (5), paradoxical fat hyperplasias (4), blisters (3), rashes (1), flu-like symptoms (1), gastroenteritis (1), and prolapsed bladder/uterus/rectum (1). Of the 11 MDRs for radio-frequency devices, 10 were burns/blisters and 1 fire.

Dr. Wulkan went on to note that 17 MDRs were reported for 1060-nm laser lipolysis, including burns/blisters (5), nodules (4), pain (3), cellulitis/abscesses (2), excessive swelling (1), neuropathy (1), and vomiting (1). There were four cases of burns on MDRs from focused/pulsed ultrasound procedures. One was on a non–FDA approved body site and another after combination radio-frequency/infrared treatment for cellulite reduction.

There were eight MDRs reported with 1440-nm laser cellulite reduction, including burn (5), unacceptable cosmesis (2), and faulty power supply (1). In addition, there were 12 MDRs reported on high-frequency ultrasound, including burns/blisters (9), subcutaneous nodules (2), and excoriation (1). Finally, vacuum-assisted submission was associated with five MDRs, including festooning/unacceptable cosmesis (2), seroma/hematoma (1), laceration (1), and nodules (1).
 

 

Dr. Wulkan acknowledged certain limitations of the study, including the fact that not all MDRs are reported to MAUDE, and that the reliability of patient reporting can be questionable. “We have to figure out if there is a natural causation between the adverse event and the treatment itself,” he said at the meeting. “The number of MDRs for any given device must be correlated to the number of procedures performed before we jump to conclusions about the safety of any given device.”

He reported having no financial disclosures. One study coauthor holds positions on advisory boards of, is a consultant for, and has intellectual property and/or stock options with various industry companies, such as Soliton and Allergan.

Laser treatment of port wine stains in infancy found safe, effective

Article Type
Changed

– Laser treatment of port wine stains in infancy is both safe and effective, with no incidence of scarring or pigmentary changes, according to results from a single-center analysis.

“Early intervention allows for treatment without general anesthesia, with faster and more complete clearance than what has been reported for treatments begun at older ages,” Hana Jeon, MD, said at the annual conference of the American Society for Laser Medicine and Surgery.

Facial port wine stain in an infant.

A recent Food and Drug Administration Drug Safety Communication warned that “repeated or lengthy used of general anesthetic and sedation drugs during surgeries or procedures in children younger than 3 years or in pregnant women during their third trimester may affect the development of children’s brains.” Dr. Jeon, a dermatologist in private practice in New York, noted that the FDA warning “places a greater importance on the already controversial topic of when to initiate port wine stain [PWS] treatments in pediatric patients, which requires repeated treatments and are often performed with general anesthesia. Without treatment, these lesions tend to get larger and thicker with time. Starting the treatment during infancy has the potential to limit the use of general anesthesia and to facilitate clearing.”

In what she said is the largest retrospective study of its kind to date, Dr. Jeon and her associates evaluated the success and safety of treating PWSs with a pulsed dye laser at the age of 1 year or younger in the office setting without general anesthesia. The patients received their first PWS treatment at their center during 2000-2017. They reviewed the charts of 197 patients to extract relevant data, including demographic information, age at the time of procedure, and treatment dates. The data cutoff was at 1 year following the initial treatment. Four physicians independently reviewed before and after photos and used the visual analogue scale to grade them.

The pulsed dye laser with dynamic cooling spray was used to minimize patient discomfort. No topical, local, or general anesthesia was used. Patients were immobilized by ancillary staff with parents present in most cases. Ocular shields were placed to allow treatment of periocular lesions.

Of the 197 patients, 63% were female, 90.1% had Fitzpatrick skin types I-III, 8.1% had type IV skin, and the rest had type V-VI skin. Most of the lesions were facial (75.6%), and 41.1% had periocular involvement. The average lesion size was 61 cm2.

 

 

The treatment settings for the pulsed dye laser were a 10-12 mm spot size delivered at a fluence of 6.5-9 J/cm2 in a pulse duration of 0.45-1.5 milliseconds. The average age at the time of first treatment was 3.4 months (range, 5-355 days), and the average number of treatments was 9.8 (range, 2-23). Most of the patients (116) were aged 0-3 months at the time of first treatment, followed by 51 aged 3-6 months, 19 aged 6-9 months, and 11 aged 9-12 months.

According to the averaged scores on the visual analogue scale assigned by physicians, 27.4% showed a 100% clearance, 39.1% showed 76%-99% improvement, 15.1% showed 51%-75% improvement, 10.7% showed 26%-50% improvement, and 7.7% showed 0%-25% improvement. No scarring or pigmentary changes were observed.

An analysis of dermatomal distribution revealed that the presence of a V1 lesion was a statistically significant predictor of a higher clearance rate, while the presence of a V3 lesion was a statistically significant predictor of a low clearance rate. “Regardless of where the lesion was, all patients did well,” she said.

Given the small proportion of patients who received their first treatment between the ages of 6 and 12 months of age, Dr. Jeon said that “further studies would be needed to elucidate whether earlier intervention helps to achieve better results.”*
 

 

Advantages of early treatment, she said, include the ability to “treat lesions before they get larger and thicker, which also decreases the risk of spontaneous bleeding. Thinner skin allows for better penetration of the laser beam, and we can also avoid using general anesthesia. Psychologically, if we’re able to clear these lesions, it can result in improved quality of life and self-esteem; not just for the patient but for the family as well.”

Dr. Jeon acknowledged certain limitations of the study, including its retrospective design, variable follow-up times, and non-standardization of photographs.

She reported having no financial disclosures.

Enhanced recovery led to fewer complications for major oncologic procedures

Article Type
Changed

– Use of an enhanced recovery protocol for oncology patients has been shown to improve outcomes in colorectal surgery but has been largely unproven in other types of major oncology operations. That prompted researchers at the University of Texas MD Anderson Cancer Center in Houston to investigate enhanced recovery protocols in multispecialty, major oncologic procedures. They found that the enhanced recovery protocol led to a reduction in complication rates and a decrease in hospital stay with no increase in readmissions, according to an analysis of more than 3,000 oncologic operations presented at the Society of Surgical Oncology Annual Cancer Symposium here.

“Patients treated with enhanced recovery did better,” Rebecca Marcus, MD, said in reporting the results. “There were decreased rates of perioperative transfusions, decreased rates of surgical site infections, decreased rates of complications, including severe complications such as wound dehiscence, pneumonia, renal failure, and unintended returns to the operating room.” She noted that the shorter hospital stays – 4 days for patients on the enhanced recovery protocol versus 5 days for those on the traditional postoperative protocol – did not result in increased readmissions.

The study reviewed 3,256 operations performed during 2011-2016 in the MD Anderson institutional American College of Surgeons National Surgical Quality Improvement Program database. The operations were colorectal (20.4%), gynecologic (19.5%), hepatobiliary (8.9%), thoracic (41.9%) and urologic (9.3%). Most employed the traditional postoperative protocol (53.4%). Colorectal and thoracic/vascular surgery were early adopters of the enhanced recovery protocol at MD Anderson.

Dr. Marcus noted that the overall complication rates were 21.9% for those treated with enhanced recovery–protocol versus 33.9% for those treated with traditional postoperative protocol (P less than .0001). The group treated with enhanced recovery protocol also had lower rates of severe complications: 8.7% vs. 11.7% (P =.0048). The study also noted a trend toward reduced National Surgical Quality Improvement Program 30-day mortality with the enhanced recover protocol (0.4% vs. 0.86%; P = .097). Readmission rates were similar between the two groups: 8.3% for enhanced recovery protocol versus 8.9% for traditional postoperative protocol.

 

 

The researchers performed a subanalysis of high-magnitude cases that had a relative value unit of 30 or more and involved operations of greater complexity, which constituted 38% of the study population. “In this group, we still saw the benefit of having treatment with an enhanced recovery protocol with decreased rates of preoperative transfusions, complications, and shorter length of stay without any recent readmission,” Dr. Marcus said. Complication rates in the high-magnitude group were 19% for the enhanced recovery protocol versus 26% for the traditional postoperative protocol in colorectal cases, 21% vs. 40% in gynecology, and 19% vs. 28% in thoracic/vascular.

“The beneficial impact of enhanced recovery appears to be maintained across all specialties and to be independent of case magnitude,” Dr. Marcus said.

She said future research of enhanced recovery in surgical oncology should focus on more long-term outcomes, “such as oncologic benefits of these protocols, especially given the known detrimental effect of the delayed return to adjuvant therapy for this patient population.”

Dr. Marcus and her coauthors reported having no financial disclosures.

Dr. Marcus noted that the overall complication rates were 21.9% for those treated with enhanced recovery–protocol versus 33.9% for those treated with traditional postoperative protocol (P less than .0001). The group treated with enhanced recovery protocol also had lower rates of severe complications: 8.7% vs. 11.7% (P =.0048). The study also noted a trend toward reduced National Surgical Quality Improvement Program 30-day mortality with the enhanced recover protocol (0.4% vs. 0.86%; P = .097). Readmission rates were similar between the two groups: 8.3% for enhanced recovery protocol versus 8.9% for traditional postoperative protocol.

 

 

The researchers performed a subanalysis of high-magnitude cases that had a relative value unit of 30 or more and involved operations of greater complexity, which constituted 38% of the study population. “In this group, we still saw the benefit of having treatment with an enhanced recovery protocol with decreased rates of preoperative transfusions, complications, and shorter length of stay without any recent readmission,” Dr. Marcus said. Complication rates in the high-magnitude group were 19% for the enhanced recovery protocol versus 26% for the traditional postoperative protocol in colorectal cases, 21% vs. 40% in gynecology, and 19% vs. 28% in thoracic/vascular.

“The beneficial impact of enhanced recovery appears to be maintained across all specialties and to be independent of case magnitude,” Dr. Marcus said.

She said future research of enhanced recovery in surgical oncology should focus on more long-term outcomes, “such as oncologic benefits of these protocols, especially given the known detrimental effect of the delayed return to adjuvant therapy for this patient population.”

High engraftment with new umbilical transplant technique

Article Type
Changed

– Recipients of hematopoietic cell transplant with umbilical cord blood CD34+ cells expanded with an aryl hydrocarbon receptor (AHR) antagonist had a significantly higher rate of engraftment and comparable survival to a historical cohort of umbilical cord blood recipients.

The robust expansion of donor umbilical cord blood seen with the new technique opens the door for better use of umbilical cord blood inventory with superior human leukocyte antigen (HLA) matching, John Wagner, MD, said at a top abstracts session of the combined annual meetings of the Center for International Blood & Marrow Transplant Research and the American Society for Blood and Marrow Transplantation.

The new technique still shared the benefits of low rates of graft-versus-host disease (GVHD) and high survival that have been seen in previous umbilical cord blood transplants, with no significant difference in overall survival, relapse, or acute or chronic GVHD.

Compared to historical controls (n = 151), patients receiving the AHR antagonist–expanded umbilical cord blood (UCB) cells with myeloablative conditioning (n = 9) saw complete and more rapid engraftment (100% vs. 89% engraftment at a median 14 days vs. 23 days; P less than .01), reported Dr. Wagner of the University of Minnesota, Minneapolis.

These and other results came from two arms of a phase 2 trial of MGTA-456 (the working name of the AHR-expanded UCB cells). Twenty patients were to receive MGTA-456 derived from partially matched umbilical cord blood units after either myeloablative or nonmyeloablative conditioning; one patient in each arm had low expansion of UCB, so a total of 18 patients received MGTA-456. Each intervention arm was compared with a historical control arm that had received conventional UCB units.

In the myeloablative arm, patient demographics and disease characteristics were similar to the control cohort except that the MGTA-456 patients were significantly heavier (93.8 kg vs. 66.7 kg; P less than .04).

 

 

Platelet recovery also rebounded faster with MGTA-456 plus myeloablative conditioning than it did with historical controls: 89% of patients had platelet recovery by a median 46 days, compared with 71% with platelet recovery by a median 64 days in the historical cohort (P less than .01).

Patients achieved rapid complete chimerism if they received myeloablative conditioning, and they had rapid rebound of CD4 counts to at least 200 by 2-3 months posttransplant, Dr. Wagner reported.

The nonmyeloablative arm had a historical control cohort of 132 patients. Characteristics were similar between the two groups except that the MGTA-456 patients were older and more likely to have high-risk disease.

Again, all patients had rapid neutrophil recovery and saw 100% engraftment with MGTA-456. Median time to engraftment was 7 days with MGTA-456 and 15 days for the historical controls (P less than .01). Platelet recovery took longer for the MGTA-456 (median of 47 vs. 107 days), but the difference was not statistically significant.
 

 

Complete chimerism was achieved rapidly with the nonmyeloablative regimen as well, and CD4 recovery was brisk, as had been seen with myeloablative conditioning before MGTA-456 transplantation.

Compared with historical controls, “MGTA-456 retains the benefits of low chronic-graft-versus host disease and high survival despite higher disease risk and age” in the study group, Dr. Wagner said. There were no significant differences between the intervention and historical control arms of the nonmyeloablative study in acute or chronic GVHD, relapse, or overall survival.

The use of MGTA-456 occurs against the backdrop of a history of high survival rates with UCB transplantation – about 70% at 5 years, Dr. Wagner said. However, when conventional culture and expansion methods for UCB were used, the median time to engraftment had been reported to be 25 days with a 79% engraftment rate. This contrasts with the mean 13 days to engraftment for peripheral blood transplants and 18 days for bone marrow transplants. All of these transplant sources, regardless of whether the transplant was matched or mismatched, have engraftment rates of 92%-96%, said Dr. Wagner (Lancet Oncol. 2010; 11[7]:653-60).

When an AHR antagonist is used for UCB expansion, hematopoietic stem cell renewal is upped because cell differentiation is blocked, which means expansion is all driven toward hematopoietic stem cell self-renewal, Dr. Wagner said. Of the 36 available samples, MGTA-456 achieved a median 327-fold expansion of CD34+ cells, which enabled investigators to deliver a median CD34+ dose of 17.5 X 106 cells/kg.
 

 

The downstream effect of the robust expansion rates is that more cord blood will be available for transplantation, and HLA matches will improve, Dr. Wagner said. Using current expansion techniques, fewer than 5% of cord blood units have a total nucleated cell count sufficient for an adult 80 kg recipient, he said, adding that use of MGTA-456 could make more than 80% of cord blood units available for adults.

According to the UCB transplant history at the University of Minnesota – where Dr. Wagner directs the pediatric blood and marrow transplantation program – of the patients who received 4/6 HLA-matched cord blood, 63% would move to a 5/6 match, and 8% would move to a full HLA match with the MGTA-456 technique. Of patients who received 5/6-matched transplants, almost one in four (23%) would move to a full 6/6 match.

Dr. Wagner and his colleagues had previously shown that adding an AHR antagonist resulted in enhanced T-cell recovery and rapid and sustained engraftment (Science. 2010;329:1345-8).

The researchers then proceeded to a phase 1-2, first-in-human trial of MGTA-456 that used a myeloablative conditioning regimen that met its primary safety endpoint of a lack of infusional toxicity or primary/secondary graft failure (Cell Stem Cell. 2016;18:144-55).
 

 

For reasons of safety, this earlier study used a double-transplant platform in which one infusion was uncultured umbilical cord blood and the other was MGTA-456. This study showed rapid neutrophil recovery when MGTA-456 was infused, with median 10.5 days to recovery, compared with a median 26.5 days for historical controls (P less than .001).

Additionally, the study showed a 19-day decrease in duration of the initial hospitalization, and all patients who received MGTA-456 had successful engraftment, Dr. Wagner said. On the strength of these results, the current trials of MGTA-456 alone – with both nonmyeloablative and myeloablative conditioning – were approved.

Multicenter clinical trials of MGTA-456 transplantation are now planned for both malignant and nonmalignant diseases. Enrollment is currently open for a phase 2 clinical trial of MGTA for inherited metabolic disorders (NCT03406962).

The study was funded by Novartis and Magenta Therapeutics. Dr. Wagner reported no other relevant disclosures.

Drug appears to aid chemo in AML

Adding an experimental compound to chemotherapy is a “promising” treatment approach for certain patients with acute myeloid leukemia (AML), according to researchers.

They tested the compound, CPI-613, in combination with high-dose cytarabine and mitoxantrone in a phase 1 trial of patients with relapsed or refractory AML.

The combination produced similar response rates in the overall patient population (50%), patients age 60 and older (47%), and those with poor-risk cytogenetics (46%).

The most common grade 3/4 adverse events (AEs) were hematologic toxicities, and there was 1 fatal AE—hypotension.

Mortality rates in this trial were similar to those observed in historical controls treated with high-dose cytarabine, mitoxantrone, and asparaginase.

“These data are very encouraging, especially for patients 60 years of age or older who have historically done very poorly with this disease,” said Timothy Pardee, MD, PhD, a professor at Wake Forest Baptist Health in Winston-Salem, North Carolina, and chief medical officer of Rafael Pharmaceuticals, Inc., the company developing CPI-613.

Dr Pardee and his colleagues reported these results in Clinical Cancer Research.

The researchers noted that CPI-613 is designed to target mitochondrial metabolism in cancer cells, and preclinical research showed that CPI-613 sensitized AML cells to chemotherapy.

To investigate this further, the team tested CPI-613 in combination with high-dose cytarabine and mitoxantrone in the phase 1 trial. The study included 66 patients with relapsed or refractory AML, as well as a patient with advanced-phase chronic myeloid leukemia (CML) who was mistakenly enrolled.

The patients’ median age was 60 (range, 21-79), and 54% were age 60 and older. Their median percentage of marrow blasts was 43%. Forty percent of patients had poor-risk cytogenetics, and 49% had intermediate-risk cytogenetics.

Most patients (72%) had no prior salvage therapy, 13% had 1 prior line of salvage, 10% had 2 prior lines, and 4% had more than 2. Thirty-one percent of patients had refractory disease.

Seven percent of patients had previously received high-dose cytarabine and mitoxantrone, and 25% had previous salvage including high-dose or intermediate-dose cytarabine.

Treatment

Patients received CPI-613, given over 2 hours, on days 1 to 5 of cycle 1. Doses ranged from 500 mg/m2 to 2750 mg/m2.

Starting on day 3, patients received 5 doses of cytarabine at 3 gm/m2 (for patients younger than 60) or 1.5 gm/m2 (for older patients) in 500 mL normal saline, over 3 hours, every 12 hours.

Patients also received 3 daily doses of mitoxantrone at 6 mg/m2 in 50 mL normal saline, given over 15 minutes, after the first, third, and fifth doses of cytarabine.

Patients were initially assigned to receive 1 cycle of treatment. Those with at least 5% blasts after the first cycle could receive a second course—either a full course or a 3-day course. And patients who responded to the first course could receive up to 2 cycles of the 3-day course.

Safety

There were 2 dose-limiting toxicities when CPI-613 was given at the 2750 mg/m2 dose. One of these toxicities was grade 3 diarrhea that didn’t respond to anti-diarrheals, and the other was grade 3 nausea that didn’t respond to antiemetics.

Because of these events, 2500 mg/m2 was deemed the maximum-tolerated dose. However, the recommended phase 2 dose is 2000 mg/m2.

The most common AEs—occurring in at least 50% of all patients who received CPI-613 (n=67)—included hemoglobin decrease (67%), hyperglycemia (67%), neutropenia (67%), thrombocytopenia (67%), hypomagnesemia (66%), leukopenia (66%), lymphopenia (66%), hypoalbuminemia (65%), hypokalemia (60%), hypocalcemia (57%), and diarrhea (55%).

All cases of neutropenia, thrombocytopenia, leukopenia, and lymphopenia were grade 3/4. Other common grade 3/4 AEs (occurring in at least 20% of patients) included hemoglobin decrease (62%), febrile neutropenia (28%), hypophosphatemia (24%), and hypokalemia (23%).

 

 

The only grade 5 AE was hypotension.

The mortality rate was 12% (n=8) at 30 days and 19% (n=13) at 60 days. The researchers said this was similar to the historical experience with high-dose cytarabine, mitoxantrone, and asparaginase. Mortality rates with this regimen were 13% at 30 days and 22% at 60 days.

Efficacy

Sixty-two patients were evaluable for response. Of the 5 patients who were not evaluable, 1 didn’t complete the first cycle of treatment, 1 was the CML patient, and 3 died before assessment.

The overall response rate was 50% (31/62). This included 26 patients with a complete response (CR) and 5 patients who had a CR with incomplete count recovery (CRi).

The rate of CR/CRi was 47% (15/32) in patients older than 60 years of age, 46% (11/24) in patients who had poor-risk cytogenetics, and 53% (8/15) when CPI-613 was given at the recommended phase 2 dose—2000 mg/m2.

The median overall survival (OS) was 6.7 months for all evaluable patients and 13.2 months for patients who achieved a CR/CRi.

The median OS was 6.9 months for patients age 60 and older, which was not significantly different from the median OS in younger patients (P=0.9642).

This study was sponsored by Wake Forest University Health Sciences and the National Cancer Institute.

The patients’ median age was 60 (range, 21-79), and 54% were age 60 and older. Their median percentage of marrow blasts was 43%. Forty percent of patients had poor-risk cytogenetics, and 49% had intermediate-risk cytogenetics.

Most patients (72%) had no prior salvage therapy, 13% had 1 prior line of salvage, 10% had 2 prior lines, and 4% had more than 2. Thirty-one percent of patients had refractory disease.

Seven percent of patients had previously received high-dose cytarabine and mitoxantrone, and 25% had previous salvage including high-dose or intermediate-dose cytarabine.

Treatment

Patients received CPI-613, given over 2 hours, on days 1 to 5 of cycle 1. Doses ranged from 500 mg/m2 to 2750 mg/m2.

Starting on day 3, patients received 5 doses of cytarabine at 3 gm/m2 (for patients younger than 60) or 1.5 gm/m2 (for older patients) in 500 mL normal saline, over 3 hours, every 12 hours.

Patients also received 3 daily doses of mitoxantrone at 6 mg/m2 in 50 mL normal saline, given over 15 minutes, after the first, third, and fifth doses of cytarabine.

Patients were initially assigned to receive 1 cycle of treatment. Those with at least 5% blasts after the first cycle could receive a second course—either a full course or a 3-day course. And patients who responded to the first course could receive up to 2 cycles of the 3-day course.

Safety

There were 2 dose-limiting toxicities when CPI-613 was given at the 2750 mg/m2 dose. One of these toxicities was grade 3 diarrhea that didn’t respond to anti-diarrheals, and the other was grade 3 nausea that didn’t respond to antiemetics.

Because of these events, 2500 mg/m2 was deemed the maximum-tolerated dose. However, the recommended phase 2 dose is 2000 mg/m2.

The most common AEs—occurring in at least 50% of all patients who received CPI-613 (n=67)—included hemoglobin decrease (67%), hyperglycemia (67%), neutropenia (67%), thrombocytopenia (67%), hypomagnesemia (66%), leukopenia (66%), lymphopenia (66%), hypoalbuminemia (65%), hypokalemia (60%), hypocalcemia (57%), and diarrhea (55%).

All cases of neutropenia, thrombocytopenia, leukopenia, and lymphopenia were grade 3/4. Other common grade 3/4 AEs (occurring in at least 20% of patients) included hemoglobin decrease (62%), febrile neutropenia (28%), hypophosphatemia (24%), and hypokalemia (23%).

 

 

The only grade 5 AE was hypotension.

The mortality rate was 12% (n=8) at 30 days and 19% (n=13) at 60 days. The researchers said this was similar to the historical experience with high-dose cytarabine, mitoxantrone, and asparaginase. Mortality rates with this regimen were 13% at 30 days and 22% at 60 days.

Efficacy

Sixty-two patients were evaluable for response. Of the 5 patients who were not evaluable, 1 didn’t complete the first cycle of treatment, 1 was the CML patient, and 3 died before assessment.

The overall response rate was 50% (31/62). This included 26 patients with a complete response (CR) and 5 patients who had a CR with incomplete count recovery (CRi).

The rate of CR/CRi was 47% (15/32) in patients older than 60 years of age, 46% (11/24) in patients who had poor-risk cytogenetics, and 53% (8/15) when CPI-613 was given at the recommended phase 2 dose—2000 mg/m2.

The median overall survival (OS) was 6.7 months for all evaluable patients and 13.2 months for patients who achieved a CR/CRi.

The median OS was 6.9 months for patients age 60 and older, which was not significantly different from the median OS in younger patients (P=0.9642).

Adding an experimental compound to chemotherapy is a “promising” treatment approach for certain patients with acute myeloid leukemia (AML), according to researchers.

They tested the compound, CPI-613, in combination with high-dose cytarabine and mitoxantrone in a phase 1 trial of patients with relapsed or refractory AML.

The combination produced similar response rates in the overall patient population (50%), patients age 60 and older (47%), and those with poor-risk cytogenetics (46%).

The most common grade 3/4 adverse events (AEs) were hematologic toxicities, and there was 1 fatal AE—hypotension.

Mortality rates in this trial were similar to those observed in historical controls treated with high-dose cytarabine, mitoxantrone, and asparaginase.

“These data are very encouraging, especially for patients 60 years of age or older who have historically done very poorly with this disease,” said Timothy Pardee, MD, PhD, a professor at Wake Forest Baptist Health in Winston-Salem, North Carolina, and chief medical officer of Rafael Pharmaceuticals, Inc., the company developing CPI-613.

Dr Pardee and his colleagues reported these results in Clinical Cancer Research.

The researchers noted that CPI-613 is designed to target mitochondrial metabolism in cancer cells, and preclinical research showed that CPI-613 sensitized AML cells to chemotherapy.

Dermatology practice gaps: improving medication management

Article Type
Changed

 

– Dermatologists don’t ordinarily peruse the ophthalmology literature. So they may be unaware that the American Academy of Ophthalmology has issued revised recommendations on weight-based dosing of hydroxychloroquine in order to minimize retinopathy risk, Erik J. Stratman, MD, noted at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

Most dermatologists routinely dose hydroxychloroquine at 400 mg/day, regardless of body weight. The former AAO recommendation, which dates back to 2011, called for dosing at up to 6.5 mg/kg of ideal body weight or 400 mg/day, whichever is lower. However, the AAO recommendation has changed in light of a large, retrospective case-control study that suggested this practice may be overdosing thin patients – thereby exposing them to increased risk of retinal toxicity and other drug-related adverse events – while at the same time possibly underdosing some obese patients, said Dr. Stratman, chairman of the department of dermatology at the Marshfield (Wisc.) Clinic.

This was one of two dermatology practice gaps he highlighted involving suboptimal medication management, the other being most dermatologists’ failure to protect their patients’ gut when prescribing prednisone.

“I think the push over the last 5 years has been ‘protect the bones, protect the bones, protect the bones.’ We’ve done better and better about protecting the bones and getting that into our conversations with patients on prednisone. But we’re not thinking so much about the gut,” the dermatologist said.

Hydroxychloroquine dosing

The former AAO recommendation was revised in response to a retrospective case-control study of retinal toxicity rates in 2,361 patients on the drug continuously for longer than 5 years. The study demonstrated that the risk of retinopathy jumped 5.7-fold with daily consumption of hydroxychloroquine at more than 5.0 mg/kg (JAMA Ophthalmol. 2014 Dec;132[12]:1453-60).

The current AAO recommendation (Ophthalmology. 2016 Jun;123[6]:1386-94) is to dose hydroxychloroquine at a daily maximum of 5.0 mg/kg of real weight, which correlated better with retinopathy risk in the case-control study than did ideal body weight. Hydroxychloroquine doesn’t accumulate well in fat.

Until now, most dermatologists have not routinely measured patients’ body weight in the office or calculated their body mass index. But Dr. Stratman advised against reliance upon a patient’s self-reported body weight, which may diverge substantially from reality. “Get yourself a good office scale – they’re not that expensive – and use it when prescribing drugs with a tight therapeutic window,” he urged.

 

 


Another key to minimizing retinopathy risk in patients on hydroxychloroquine is to pay careful attention to how long they’ve been on the drug. As the years go by in patients being treated for cutaneous lupus or other dermatologic disorders where decades-long therapy is often a mainstay, it’s important to check with patients and make sure they’re getting annual ophthalmologic screening for irreversible retinal toxicity by both threshold visual fields and spectral domain optical coherence tomography. In the large, practice-changing retrospective study, patients on hydroxychloroquine at 4.0-5.0 mg/kg daily had a prevalence of retinopathy of less than 2% during the first 10 years of therapy, but the rate shot up to nearly 20% after 20 years of use, Dr. Stratman observed.

He highlighted as helpful an updated review of the use of hydroxychloroquine in dermatology recently published by Anthony P. Fernandez, MD, PhD, of the department of dermatology at the Cleveland Clinic (J Am Acad Dermatol. 2017 Jun;76[6]:1176-82).

Dr. Fernandez recommends following the AAO guidance to dose the drug at 5.0 mg/kg or less of actual body weight in thin or normal-weight patients; however, he departed from the ophthalmologists with regard to treatment of obese patients. Because dosing based on actual weight could potentially lead to relative overdosing in obese patients, in that growing population he recommends calculating the dose based upon 5.0 mg/kg of actual body weight, as well as the dose based on 6.5 mg/kg of ideal body weight, then prescribing the lower of the two, up to a maximum of 400 mg/day.

“The current recommendation is really about not overdosing thin patients. Basically, dosing is not so difficult for obese people because if you weigh more than 175 pounds, you’re going to get 400 mg/day,” Dr. Stratman explained.

That 400 mg/day ceiling is not cast in stone, he continued. The guideline recommends that, if a patient is a nonresponder to several months of hydroxychloroquine at 400 mg/day, it’s worthwhile to order a drug blood level. If it’s not above the efficacy threshold of more than 750 ng/mL, it’s appropriate to titrate up.
 

 

Protecting against prednisone-induced gastritis

“We underprotect the gut,” Dr. Stratman asserted.

He referred to a recent comprehensive dermatologic review of the prevention and management of glucocorticoid-related side effects, especially the part on peptic ulcer disease (J Am Acad Dermatol. 2017 Jan;76[1]:11-6). This is an issue that heretofore hadn’t been much emphasized in the dermatology literature.

“I read this and thought, ‘Gosh, I’m not really having a conversation with my patients about a review of systems for gut protection as I should. And I certainly haven’t been thinking about prescribing PPIs [proton pump inhibitors] for my patients,’” he recalled.

Dr. Stratman polled his Hawaii Dermatology Seminar audience as to who had ever prescribed a PPI. Most indicated with their electronic clickers that they had never done so.

“This is what a practice gap is,” he commented. “You read the literature and you say, ‘Oh, I guess that makes sense. Maybe I should be doing that more often, or making sure it gets done.’”

“I don’t want to come across as saying, ‘For everybody we put on prednisone we should be giving vitamin D, calcium, and a PPI.’ That’s not the message. The message is, assess your patient – or make sure your patient is being assessed – for risk of peptic ulcer disease. And if you don’t feel comfortable prescribing a PPI, please get the patient connected with their primary care provider, who should,” Dr. Stratman said.

 

 


The authors of the dermatology review made a case for screening for GI risk factors in every patient who is going to receive an oral glucocorticoid. The ones who absolutely should be prescribed a PPI unless contraindicated include patients who are taking daily aspirin or NSAIDs for an essential reason, such as cardiovascular protection or significant arthritic pain. The authors suggest consideration of a PPI in patients with other, less potent risk factors for peptic ulcer disease, including a history of ulcer disease, gastroesophageal reflux disease, Barrett’s esophagus, heavy smoking, heavy alcohol consumption, age greater than 65, and concomitant use of other medications with an associated risk of peptic ulcer disease – such as bisphosphonates, “which you may have just put them on to protect their bones,” Dr. Stratman noted.

Of course, PPIs come with side effects of their own, including increased fracture risk, Clostridium difficile infections, and rebound acid secretion.

Dr. Stratman reported having no financial conflicts regarding his presentation.

Article Type
Changed

 

Spending on indoor tanning in the United States has dropped considerably since 2011, despite increased overall spending on services by consumers, according to investigators from the University of Pennsylvania.

Since the Affordable Care Act was passed in 2010 with a 10% excise tax on indoor tanning services, consumer spending, as reflected by collections of that tax, has dropped 13% – from $86.3 million in 2011 to $75.1 in 2016. The amount collected actually increased in 2012 and 2013, when revenue was $91.7 million, making the drop since that peak an even larger 18.1%. Overall personal spending on services, in the meantime, rose steadily from $7.1 billion in 2011 to $8.7 billion in 2016, or 22.6%, Kishore L. Jayakumar and Jules B. Lipoff, MD, said in JAMA Dermatology.

Over that same period, the number of quarterly returns from indoor tanning providers dropped 21.3% as it went from 47,000 to 37,000, with the high point coming in 2013, when the figure was 49,000. Putting the two tax measures together results in mean collections per quarterly return of $1,835 in 2012 and $2,029 in 2016, for an increase of 10.5%, they reported.

These findings, when combined with earlier surveys demonstrating “that the prevalence of indoor tanning had been increasing as late as 2009 [imply] a trend reversal coinciding with the tax’s implementation,” but they do not definitively show causation and should be considered “secondary to the public health objective of deterring indoor tanning,” the investigators wrote.

Mr. Jayakumar reported receiving “enrolled agent” status from the Internal Revenue Service. They did not report any other conflicts.

Baseline Symptoms May Predict Psychosis in Parkinson’s Disease

Article Type
Changed
A neuroimaging biomarker appears to identify a diffuse malignant subtype of Parkinson’s disease and predict rapid disease progression.

REM sleep behavior disorder (RBD), excessive daytime sleepiness (EDS), and a high burden of autonomic symptoms are associated with increased risk of future psychotic symptoms in patients with Parkinson’s disease, according to research published online ahead of print April 4 in Neurology. These symptoms also correlate with low density of the cholinergic nucleus 4 (Ch4) of the basal forebrain.

Data From the Parkinson’s Progression Markers Initiative

Parkinson’s disease psychosis indicates advanced disease and is associated with dementia and increased mortality. Research indicates that degeneration of the nucleus basalis of Meynert is characteristic of Parkinson’s disease and Parkinson’s disease dementia, but this brain region is difficult to measure with MRI because of its size. It is possible, however, to measure Ch4, which incorporates the nucleus basalis of Meynert.

Matthew J. Barrett, MD, Assistant Professor of Neurology at the University of Virginia in Charlottesville, and colleagues studied a cohort of patients with de novo Parkinson’s disease to identify baseline clinical risk factors for future psychotic symptoms and to assess the relationship between baseline Ch4 density and future psychotic symptoms. All participants were untreated at baseline and had enrolled in the Parkinson’s Progression Markers Initiative (PPMI), a prospective, longitudinal, observational study.

Matthew J. Barrett, MD


Physicians assessed participants with the Movement Disorders Society-Unified Parkinson Disease Rating Scale (MDS-UPDRS) at each visit. Item 1.2 assesses hallucinations and psychosis during the previous week. The investigators considered any score above 0 on this item to indicate the presence of psychotic symptoms.

Investigators evaluated patients’ autonomic symptoms with the Scales for Outcomes in Parkinson’s Disease-Autonomic (SCOPA-AUT) and administered the RBD screening questionnaire and the Epworth Sleepiness Scale. They determined the density of each participant’s basal forebrain using brain MRI sequences that they obtained from the PPMI database.

Ch4 Density Could Predict Psychotic Symptoms

The investigators included 423 participants in their analysis. The population’s mean age at enrollment was approximately 61.5, and about 35% of the population was female. Mean disease duration was 0.57 years. The population’s median number of clinical visits was 11, and the median last visit occurred at 54 months after baseline.

In all, 138 participants (32.6%) reported psychotic symptoms at least once, and 84 (19.9%) reported them more than once. Dr. Barrett and colleagues identified 17 patients who, having once reported psychotic symptoms, reported these symptoms at each subsequent visit. Among patients who reported psychotic symptoms, approximately 79% reported them at only one visit.

The investigators categorized patients into three groups according to the number of psychotic events. The groups included participants with no psychotic events, those with one psychotic event, and those with two or more psychotic events.

 

 

After performing multivariate logistic regression and adjusting the results for age and sex, Dr. Barrett and colleagues found that greater autonomic symptoms (odds ratio [OR], 1.07 for a one-unit change in SCOPA-AUT), the presence of RBD (OR, 1.9), and EDS (OR, 2.5) at baseline were associated with increased risk of reporting psychotic symptoms on two or more occasions, compared to no or one psychotic event.

A logistic regression model adjusted for age and sex indicated that greater autonomic symptoms (OR, 1.08 for a one-unit change in SCOPA-AUT) and EDS (OR, 1.8) at baseline were associated with increased risk of psychotic symptoms on one or more occasions. A Cox regression model adjusted for EDS (hazard ratio [HR], 1.5) indicated that greater autonomic symptoms (HR, 1.03 for a one-unit change in SCOPA-AUT) and presence of RBD (HR, 1.47) were associated with increased risk of having a first psychotic event.

At the last assessment, patients with Parkinson’s disease and two or more psychotic events were more likely to have the postural instability and gait difficulty motor phenotype and lower scores on the Montreal Cognitive Assessment, Letter Number Sequencing test, and Symbol Digit Modalities Test.

The investigators had data about cholinergic nuclei densities at baseline for 228 participants with Parkinson’s disease and 101 controls. Ch4 density in Parkinson’s disease was associated with lower risk of reporting psychotic symptoms on two or more occasions (OR, 0.96 for an increase in density of one unit). Mean Ch4 densities were 1.7% greater for the control group, compared with the Parkinson’s disease group. Participants with Parkinson’s disease and two or more psychotic events had lower baseline Ch4 density, compared with healthy controls, but participants with Parkinson’s disease with no or one psychotic event did not.

In linear regression models adjusted for age and sex, autonomic symptoms were associated with baseline Ch4 density, but EDS and RBD were not. Having comorbid EDS and RBD was associated with lower Ch4 density.

 

 

Results Do Not Establish Causation

“Prior studies reported that EDS was associated with hallucinations in Parkinson’s disease, but we are not aware of other studies that found EDS to be a predictor of future psychotic symptoms,” said Dr. Barrett and colleagues.

“In univariate comparisons, participants with Parkinson’s disease with three or more psychotic events had worse visuospatial function, compared with those with two psychotic events. Considering the greater impairment in visuospatial and visuoperceptive function reported in Parkinson’s disease with visual hallucinations, this association should be evaluated in the future in the PPMI Parkinson’s disease cohort as additional follow-up visits occur.”

The current study’s finding of an association between autonomic dysfunction, RBD, and EDS and baseline Ch4 density in Parkinson’s disease is consistent with a recent analysis that found that the same symptoms were associated with a diffuse malignant subtype of Parkinson’s disease, said the authors. “Our finding that these three nonmotor symptoms are linked to future psychotic symptoms validates the prognostic value of these symptoms in predicting worse outcomes early in disease.”

Evidence does not support a causal relationship between lower Ch4 density and autonomic dysfunction, RBD, and EDS. These four characteristics may be associated with widespread subcortical pathology. “The relationship between this triad of clinical symptoms and lower Ch4 density supports the potential utility of this neuroimaging biomarker to identify a diffuse malignant subtype of Parkinson’s disease and to predict more rapid disease progression,” said Dr. Barrett and colleagues.

Common infections are potent risk factor for MI, stroke

Article Type
Changed

 

A respiratory or urinary tract infection severe enough to land a patient in the hospital constitutes a novel independent risk factor for subsequent ischemic heart disease and ischemic stroke, according to a “big data” registry study from the United Kingdom.

“Our data show infection was just as much a risk factor or more compared with the traditional atherosclerotic cardiovascular disease risk factors,” Paul Carter, MD, said at the annual meeting of the American College of Cardiology.

Dr. Carter of Aston Medical School in Birmingham, England, presented a retrospective analysis from the ACALM (Algorithm for Comorbidities Associated with Length of stay and Mortality) study of administrative data on all of the more than 1.22 million patients admitted to seven U.K. hospitals in 2000-2013. His analysis included all 34,027 adults aged 40 years or older admitted with a urinary tract or respiratory infection on their index hospitalization who had no history of ischemic heart disease or ischemic stroke.

These patients, with a mean age of 73 years, 59% of whom were women, were compared with an equal number of age- and gender-matched adults whose index hospitalization was for reasons other than ischemic heart disease, stroke, urinary tract infection (UTI), or respiratory infection – the two most common infections resulting in hospitalization in the United Kingdom.



Patients with a respiratory infection or UTI had a 9.9% incidence of new-onset ischemic heart disease and a 4.1% rate of ischemic stroke during follow-up starting upon discharge from their index hospitalization, significantly higher than the 5.9% and 1.5% rates in controls. In a multivariate logistic regression analysis adjusted for demographics, standard cardiovascular risk factors, and the top 10 causes of mortality in the United Kingdom, patients with respiratory infection or UTI as their admitting diagnosis had a 1.36-fold increased likelihood of developing ischemic heart disease post discharge and a 2.5-fold greater risk of ischemic stroke than matched controls.

Moreover, mortality following diagnosis of ischemic heart disease was 75.2% in patients whose index hospitalization was for infection, compared with 51.1% in controls who developed ischemic heart disease without a history of hospitalization for infection, for an adjusted 2.98-fold increased likelihood of death. Similarly, mortality after an ischemic stroke was 59.8% in patients with a prior severe infection, compared with 30.8% in controls, which translated to an adjusted 3.1-fold increased risk of death post stroke in patients with a prior hospitalization for infection.

In the multivariate analysis, hospitalization for infection was a stronger risk factor for subsequent ischemic stroke than was atrial fibrillation, heart failure, type 1 or type 2 diabetes, hypertension, or hyperlipidemia. The risk of ischemic heart disease in patients with an infectious disease hospitalization was similar to the risks associated with most of those recognized risk factors.

 

 


Two possible mechanisms by which infection might predispose to subsequent ischemic heart disease and stroke are via a direct effect whereby pathogens such as Chlamydia pneumoniae are taken up into arterial plaques, where they cause a local inflammatory response, or an indirect effect in which systemic inflammation primes the atherosclerotic plaque through distribution of inflammatory cytokines, according to Dr. Carter.

He said the ACALM findings are particularly intriguing when considered in the context of the 2017 results of the landmark CANTOS trial, in which canakinumab (Ilaris), a targeted anti-inflammatory agent that inhibits the interleukin-1 beta innate immunity pathway, reduced recurrent ischemic events in post-MI patients who had high systemic inflammation as evidenced by their elevated C-reactive protein level but a normal-range LDL cholesterol (N Engl J Med. 2017 Aug 27. doi: 10.1056/NEJMoa1707914).

“If atherosclerosis is an inflammatory condition, this begs the question of whether other inflammatory conditions, like infection, which induces a large systemic inflammatory response, might drive atherosclerosis,” Dr. Carter commented.

“It’s now very well understood that inflammatory mediators, cells, and processes are involved in every step from the initial endothelial dysfunction that leads to uptake of LDL, inflammatory cells, and monocytes all the way through to plaque progression and rupture, where Th1 cytokines have been implicated in causing that rupture, and ultimately in patient presentation at the hospital,” he added.

 

 


He sees the ACALM findings as hypothesis generating, serving to help lay the groundwork for future clinical trials of vaccine or anti-inflammatory antibiotic therapies.

Dr. Carter reported having no financial conflicts related to his presentation.

He said the ACALM findings are particularly intriguing when considered in the context of the 2017 results of the landmark CANTOS trial, in which canakinumab (Ilaris), a targeted anti-inflammatory agent that inhibits the interleukin-1 beta innate immunity pathway, reduced recurrent ischemic events in post-MI patients who had high systemic inflammation as evidenced by their elevated C-reactive protein level but a normal-range LDL cholesterol (N Engl J Med. 2017 Aug 27. doi: 10.1056/NEJMoa1707914).

“If atherosclerosis is an inflammatory condition, this begs the question of whether other inflammatory conditions, like infection, which induces a large systemic inflammatory response, might drive atherosclerosis,” Dr. Carter commented.

“It’s now very well understood that inflammatory mediators, cells, and processes are involved in every step from the initial endothelial dysfunction that leads to uptake of LDL, inflammatory cells, and monocytes all the way through to plaque progression and rupture, where Th1 cytokines have been implicated in causing that rupture, and ultimately in patient presentation at the hospital,” he added.

 

 


He sees the ACALM findings as hypothesis generating, serving to help lay the groundwork for future clinical trials of vaccine or anti-inflammatory antibiotic therapies.

Dr. Carter reported having no financial conflicts related to his presentation.

A respiratory or urinary tract infection severe enough to land a patient in the hospital constitutes a novel independent risk factor for subsequent ischemic heart disease and ischemic stroke, according to a “big data” registry study from the United Kingdom.

“Our data show infection was just as much a risk factor or more compared with the traditional atherosclerotic cardiovascular disease risk factors,” Paul Carter, MD, said at the annual meeting of the American College of Cardiology.

Dr. Carter of Aston Medical School in Birmingham, England, presented a retrospective analysis from the ACALM (Algorithm for Comorbidities Associated with Length of stay and Mortality) study of administrative data on all of the more than 1.22 million patients admitted to seven U.K. hospitals in 2000-2013. His analysis included all 34,027 adults aged 40 years or older admitted with a urinary tract or respiratory infection on their index hospitalization who had no history of ischemic heart disease or ischemic stroke.

These patients, with a mean age of 73 years, 59% of whom were women, were compared with an equal number of age- and gender-matched adults whose index hospitalization was for reasons other than ischemic heart disease, stroke, urinary tract infection (UTI), or respiratory infection – the two most common infections resulting in hospitalization in the United Kingdom.



Patients with a respiratory infection or UTI had a 9.9% incidence of new-onset ischemic heart disease and a 4.1% rate of ischemic stroke during follow-up starting upon discharge from their index hospitalization, significantly higher than the 5.9% and 1.5% rates in controls. In a multivariate logistic regression analysis adjusted for demographics, standard cardiovascular risk factors, and the top 10 causes of mortality in the United Kingdom, patients with respiratory infection or UTI as their admitting diagnosis had a 1.36-fold increased likelihood of developing ischemic heart disease post discharge and a 2.5-fold greater risk of ischemic stroke than matched controls.

Moreover, mortality following diagnosis of ischemic heart disease was 75.2% in patients whose index hospitalization was for infection, compared with 51.1% in controls who developed ischemic heart disease without a history of hospitalization for infection, for an adjusted 2.98-fold increased likelihood of death. Similarly, mortality after an ischemic stroke was 59.8% in patients with a prior severe infection, compared with 30.8% in controls, which translated to an adjusted 3.1-fold increased risk of death post stroke in patients with a prior hospitalization for infection.

In the multivariate analysis, hospitalization for infection was a stronger risk factor for subsequent ischemic stroke than was atrial fibrillation, heart failure, type 1 or type 2 diabetes, hypertension, or hyperlipidemia. The risk of ischemic heart disease in patients with an infectious disease hospitalization was similar to the risks associated with most of those recognized risk factors.

Key clinical point: Once patients have been hospitalized for a respiratory infection or UTI, their postdischarge risk of ischemic stroke is 2.5-fold greater than in those without such a history.

Major finding: Patients with a history of hospitalization for UTI or a respiratory infection who later develop ischemic heart disease or stroke have a threefold higher mortality risk than those without such a hospitalization.

Study details: This was a retrospective study of more than 68,000 subjects in the U.K. ACALM registry study.

Disclosures: The study presenter reported having no financial conflicts of interest.

Carboxytherapy caused small yet transient subcutaneous fat reduction

Article Type
Changed

 

Carboxytherapy – the insufflation of carbon dioxide gas into the skin layers – may provide a small but transient decrease in subcutaneous fat, a small randomized, controlled trial demonstrated.

“Carboxytherapy has been previously used therapeutically to reduce fat, and studies of carboxytherapy have been done in the past as well,” the study’s senior author, Murad Alam, MD, said in an interview in advance of a poster session at the annual conference of the American Society for Laser Medicine and Surgery Inc. “However, earlier studies have not been controlled trials.”

For the split-body study, he and his associates enrolled 16 adults and randomized one side of their body to receive infusions of 1,000 cc of CO2 every week for 5 weeks in the flank region, while the contralateral side received sham treatments. Outcomes of interest included fat layer thickness using a diagnostic ultrasound, total circumference, and body weight, said Dr. Alam, vice-chair of the department of dermatology and chief of the division of cutaneous and aesthetic surgery at Northwestern University, Chicago. He reported that a significant difference in fat thickness was observed in the carboxytherapy-treated side 1 week after the last treatment (P = .011), but this difference was not maintained at 28 weeks as measured by diagnostic ultrasound. Total circumference decreased nominally but not significantly. Body weights did not significantly change throughout the study.

Dr. Murad Alam
“Carboxytherapy is a promising fat reduction therapy in that it does not require expensive disposable products, or nonnatural materials,” Dr. Alam said. “What could be more natural than the carbon dioxide present in all living things and in the air? On the other hand, as it is typically performed, it appears not to have a durable effect. We were a little disappointed that did not appear to persist for many months, and gradually diminished. We need to better understand how to space treatments, and how to schedule treatments, to maximize the cumulative effect and the duration of this benefit.”

Dr. Alam acknowledged that the study’s small sample size is a limitation. “We do think we did enough treatments, five per side, to obtain an effect if one were to be seen,” he said. The researchers reported having no financial disclosures.
