Disc Degeneration in Chronic Low Back Pain: Can Stem Cells Help?
TOPLINE:
Allogeneic bone marrow–derived mesenchymal stromal cells (BM-MSCs) are safe but do not show efficacy in treating intervertebral disc degeneration (IDD) in patients with chronic low back pain.
METHODOLOGY:
- The RESPINE trial assessed the efficacy and safety of a single intradiscal injection of allogeneic BM-MSCs in the treatment of chronic low back pain caused by single-level IDD.
- Overall, 114 patients (mean age, 40.9 years; 35% women) with IDD-associated chronic low back pain that was persistent for 3 months or more despite conventional medical therapy and without previous surgery, were recruited across four European countries from April 2018 to April 2021 and randomly assigned to receive either intradiscal injections of allogeneic BM-MSCs (n = 58) or sham injections (n = 56).
- The first co-primary endpoint was the rate of response to BM-MSC injections at 12 months after treatment, defined as improvement of at least 20% or 20 mm in the Visual Analog Scale for pain or improvement of at least 20% in the Oswestry Disability Index for functional status.
- The secondary co-primary endpoint was structural efficacy, based on disc fluid content measured by quantitative T2 MRI between baseline and month 12.
TAKEAWAY:
- At 12 months post-intervention, 74% of patients in the BM-MSC group were classified as responders compared with 68.8% in the placebo group. However, the difference between the groups was not statistically significant.
- The probability of being a responder was higher in the BM-MSC group than in the sham group; however, the findings did not reach statistical significance.
- The average change in disc fluid content, indicative of disc regeneration, from baseline to 12 months was 37.9% in the BM-MSC group and 41.7% in the placebo group, with no significant difference between the groups.
- The incidence of adverse events and serious adverse events was not significantly different between the treatment groups.
IN PRACTICE:
“BM-MSC represents a promising opportunity for the biological treatment of IDD, but only high-quality randomized controlled trials, comparing it to standard care, can determine whether it is a truly effective alternative to spine fusion or disc replacement,” the authors wrote.
SOURCE:
The study was led by Yves-Marie Pers, MD, PhD, Clinical Immunology and Osteoarticular Diseases Therapeutic Unit, CHRU Lapeyronie, Montpellier, France. It was published online on October 11, 2024, in Annals of the Rheumatic Diseases.
LIMITATIONS:
MRI results were collected from only 55 patients across both trial arms, which may have affected the statistical power of the findings. Although patients were monitored for up to 24 months, the long-term efficacy and safety of BM-MSC therapy for IDD may not have been fully captured. Selection bias could not be excluded because of the difficulty in accurately identifying patients with chronic low back pain caused by single-level IDD.
DISCLOSURES:
The study was funded by the European Union’s Horizon 2020 Research and Innovation Programme. The authors declared no conflicts of interest.

Controlling Six Risk Factors Can Combat CKD in Obesity
TOPLINE:
Optimal management of blood pressure, A1c levels, low-density lipoprotein cholesterol (LDL-C), albuminuria, smoking, and physical activity may reduce the excess risk for chronic kidney disease (CKD) typically linked to obesity. The protective effect is more pronounced in men, in those with lower healthy food scores, and in users of diabetes medication.
METHODOLOGY:
- Obesity is a significant risk factor for CKD, but it is unknown if managing multiple other obesity-related CKD risk factors can mitigate the excess CKD risk.
- Researchers assessed CKD risk factor control in 97,538 participants with obesity from the UK Biobank and compared them with an equal number of age- and sex-matched control participants with normal body weight and no CKD at baseline.
- Participants with obesity were assessed for six modifiable risk factors: Blood pressure, A1c levels, LDL-C, albuminuria, smoking, and physical activity.
- Overall, 2487, 12,720, 32,388, 36,988, and 15,381 participants with obesity had at most two, three, four, five, and six risk factors under combined control, respectively, with the two or fewer group serving as the reference.
- The primary outcome was incident CKD and the degree of combined risk factor control in persons. The CKD risk and risk factor control in participants with obesity were also compared with CKD incidence in matched normal weight participants.
TAKEAWAY:
- During a median follow-up period of 10.8 years, 3954 cases of incident CKD were reported in participants with obesity and 1498 cases in matched persons of normal body mass index (BMI).
- In a stepwise pattern, optimal control of each additional risk factor was associated with 11% (adjusted hazard ratio [aHR], 0.89; 95% CI, 0.86-0.91) reduction in the incidence of CKD events, down to a 49% reduction in CKD incidence (aHR, 0.51; 95% CI, 0.43-0.61) for combined control of all six risk factors in participants with obesity.
- The protective effect of combined control of risk factors was more pronounced in men vs women, in those with lower vs higher healthy diet scores, and in users vs nonusers of diabetes medication.
- A similar stepwise pattern emerged between the number of risk factors controlled and CKD risk in participants with obesity compared with matched individuals of normal BMI, with the excess CKD risk eliminated in participants with obesity with six risk factors under control.
IN PRACTICE:
“Comprehensive control of risk factors might effectively neutralize the excessive CKD risk associated with obesity, emphasizing the potential of a joint management approach in the prevention of CKD in this population,” the authors wrote.
SOURCE:
The study was led by Rui Tang, MS, Department of Epidemiology, School of Public Health and Tropical Medicine, Tulane University, New Orleans, Louisiana. It was published online in Diabetes, Obesity and Metabolism.
LIMITATIONS:
The evaluated risk factors for CKD were arbitrarily selected, which may not represent the ideal group. The study did not consider the time-varying effect of joint risk factor control owing to the lack of some variables such as A1c. The generalizability of the findings was limited because over 90% of the UK Biobank cohort is composed of White people and individuals with healthier behaviors compared with the overall UK population.
DISCLOSURES:
The study was supported by grants from the US National Heart, Lung, and Blood Institute and the National Institute of Diabetes and Digestive and Kidney Diseases. The authors declared no conflicts of interest.

Current Hydroxychloroquine Use in Lupus May Provide Protection Against Cardiovascular Events
TOPLINE:
Current use of hydroxychloroquine is associated with a lower risk for myocardial infarction (MI), stroke, and other thromboembolic events in patients with systemic lupus erythematosus (SLE). This protective effect diminishes after discontinuation of hydroxychloroquine treatment.
METHODOLOGY:
- Researchers used a nested case-control design to evaluate the association between exposure to hydroxychloroquine and the risk for cardiovascular events in patients with SLE.
- They included 52,883 adults with SLE (mean age, 44.23 years; 86.6% women) identified from the National System of Health Databases, which includes 99% of the French population.
- Among these, 1981 individuals with composite cardiovascular conditions were matched with 16,892 control individuals without cardiovascular conditions.
- Patients were categorized on the basis of hydroxychloroquine exposure into current users (last exposure within 90 days before a cardiovascular event), remote users (91-365 days before), and nonusers (no exposure within 365 days).
- The study outcomes included a composite of cardiovascular events, including MI, stroke (including transient ischemic attack), and other thromboembolic events such as phlebitis, thrombophlebitis, venous thrombosis, venous thromboembolism, and pulmonary embolism.
TAKEAWAY:
- Current hydroxychloroquine users had lower odds of experiencing a composite cardiovascular outcome than nonusers (adjusted odds ratio [aOR], 0.63; 95% CI, 0.57-0.70).
- The odds of MI (aOR, 0.72; 95% CI, 0.60-0.87), stroke (aOR, 0.71; 95% CI, 0.61-0.83), and other thromboembolic events (aOR, 0.58; 95% CI, 0.48-0.69) were also lower among current users than among nonusers.
- No significant association was found for remote hydroxychloroquine exposure and the risk for composite cardiovascular events, MI, stroke, and other thromboembolic events.
IN PRACTICE:
“These findings support the protective association of hydroxychloroquine against CV [cardiovascular] events and underscore the importance of continuous hydroxychloroquine therapy for patients diagnosed with SLE,” the authors wrote.
SOURCE:
The study was led by Lamiae Grimaldi-Bensouda, PharmD, PhD, Department of Pharmacology, Hospital Group Paris-Saclay, Assistance Publique-Hôpitaux de Paris, France. It was published online on August 30, 2024, in JAMA Network Open.
LIMITATIONS:
The observational nature of the study may have introduced confounding. Current hydroxychloroquine users were younger than nonusers, with an average age difference of almost 5 years. Current hydroxychloroquine users had a twofold longer duration of onset of SLE and had a higher prevalence of chronic kidney disease compared with nonusers.
DISCLOSURES:
This study was funded by the Banque pour l’Investissement, Deeptech. Some authors declared having financial ties with various institutions and companies outside of the current study.
