Abstract

Background

This study aims to evaluate serum cytokine levels in individuals with primary Restless Legs Syndrome (RLS) and analyze their correlation with RLS symptom severity, sleep disturbances, anxiety, and depression.

Methods

A case-control study was conducted involving 87 primary RLS patients and 100 healthy individuals undergoing health check-ups. Serum cytokine levels were assessed, and RLS severity was evaluated using the International Restless Legs Syndrome Study Group (IRLSSG) rating scale. Additionally, the Pittsburgh Sleep Quality Index (PSQI), 24-item Hamilton Depression Rating Scale (HAMD24), and 14-item Hamilton Anxiety Rating Scale (HAMA14) were utilized to assess symptom severity, sleep disturbances, and emotional states in RLS patients.

Results

Serum cytokine levels, including IL-6 and TNF-α, were significantly higher in RLS patients compared to controls (P < 0.05). Adjustment for disease duration, sex, age, BMI, SBP, and DBP revealed an independent association between serum IL-6 and RLS (OR = 1.46; 95% CI = 1.02–1.93; P = 0.003). Linear regression analysis demonstrated a significant correlation between IL-6 levels and IRLS scores (β = 0.123, P = 0.008).

Conclusion

Elevated circulating levels of inflammatory cytokines in RLS patients suggest a potential role of inflammation in the pathogenesis of primary RLS. Additionally, serum cytokine levels correlate closely with disease severity.

Belastungs-Malaise erschwert Reha bei Long-COVID

Um Menschen mit Langzeitfolgen von COVID-19 wirksam zu rehabilitieren, ist eine etwaige Post-Exertional Malaise unbedingt mitzuberücksichtigen, und das Trainingsprogramm entsprechend anzupassen.

Neuartige Antikörpertherapie bremst MS über zwei Jahre hinweg

Eine Therapie mit dem C40-Ligand-Blocker Frexalimab kann MS-Schübe und neue MRT-Läsionen über zwei Jahre hinweg verhindern. Dafür spricht die Auswertung einer offen fortgeführten Phase-2-Studie.

Therapiestopp bei älteren MS-Kranken kann sich lohnen

Eine Analyse aus Kanada bestätigt: Setzen ältere MS-Kranke die Behandlung mit Basistherapeutika ab, müssen sie kaum mit neuen Schüben und MRT-Auffälligkeiten rechnen.

Positive Phase IIb-Studie zu spezifischer CAR-T-Zell-Therapie bei Myasthenia gravis

Eine auf das B-Zell-Reifungsantigen gerichtete mRNA-basierte CAR-T-Zell-Therapie wurde jetzt in einer ersten Phase IIb-Studie zur Behandlung der generalisierten Myasthenia gravis mit Placebo verglichen.
