Mycophenolate mofetil (MMF) is an immunosuppressive agent (IS) which is widely prescribed in neuromyelitis optica spectrum disorder (NMOSD) patients. We aim to assess the efficacy and safety of MMF in controlling relapse and disease severity. Eligible studies obtained from the EMBASE and Ovid MEDLINE databases were studies of NMOSD patients treated with MMF, which reported treatment outcomes as Annualized Relapse Rate (ARR) or Expanded Disability Status Scale (EDSS) before and after treatment. Fifteen studies included 1047 patients, of whom 915 (87.4%) were aquaporin-4 immunoglobulin seropositive. The total number of patients that received MMF was 799. A meta-analysis on ARR was conducted in 200 patients from 4 studies and on EDSS in 158 patients from 3 studies. The result showed a significant improvement with a mean reduction of 1.13 [95% confidence interval (CI) 0.60–1.65] in ARR, and a mean reduction of 0.85 (95% CI 0.36–1.34) in EDSS after MMF therapy. Adverse events occurred in 106 (17.8%) of 594 patients during MMF therapy. This systematic review and meta-analysis showed that using MMF as a preventive therapy in NMOSD patients can significantly reduce relapse rates and improve disease severity with acceptable tolerability.

Objective: To conduct systematic review and meta‐analysis for the efficacy of therapeutic plasma exchange (TPE) for neuromyelitis optica spectrum disorder (NMOSD) with an acute attack.Methods: Systematic review was performed using EMBASE and OVID/Medline database. The eligible studies must be the studies of NMOSD patients treated with TPE during the acute phase. They must report treatment outcomes using either Expanded Disability Status Scale (EDSS) or visual acuity (VA) before and after the therapy. Pooled mean difference (MD) was then calculated by combining MDs of each study using the random‐effects model.Results: Fifteen studies were identified; eleven with 241 NMOSD patients reported EDSS outcome and four studies with 103 NMOSD reported visual outcomes. The meta‐analysis demonstrated a significantly decreased in EDSS after TPE treatment for NMOSD with an acute attack with the pooled MD of 0.83 (95% CI, 0.26–1.40; I² 69%) comparing pretreatment to immediate posttreatment and 2.13 (95% CI, 1.55–2.70; I² 31%) comparing pretreatment to posttreatment at 6 months to 1‐year follow‐up. Unfortunately, only one of the four studies evaluating visual outcomes reported standard deviation in association with mean LogMAR; therefore, the meta‐analysis cannot be conducted. Nonetheless, all studies consistently demonstrated the benefit of TPE with improved VA and/or LogMAR after treatment.Interpretation: This systematic review and meta‐analysis showed the benefit of TPE during the NMOSD attack with a significantly improved disability status immediately after treatment and during follow‐up.

Background: Complementary and alternative medications (CAM) are common among patients with multiple sclerosis (MS) for physical and psychological support. However, there is insufficient data regarding the application of CAM in the different cultures and beliefs of each community as well as patient's status. Objective: To evaluate the prevalence and modalities of the use of CAM among patients with central nervous system idiopathic inflammatory demyelinating diseases (CNS-IIDD) in a tertiary care hospital Methods: A cross-sectional study was conducted at Siriraj Hospital from June to December 2021 involving patients with MS, neuromyelitis optic spectrum disorders (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), idiopathic transverse myelitis (iTM), and optic neuritis (ON) to examine the prevalence and mode of CAM use and its correlation with patient characteristics. Results: There were 107 patients. The diagnoses were MS (38), NMOSD (55), MOGAD (5), iTM (7), and ON (2). Most of the patients were female (89.7%), and 61.7% were diagnosed over 5 years. The mean Expanded Disability Status Scale was 2.63 (S.D., 2.38), and the median ambulation index was 0 (range 0–8.5). There were 68 patients (63.6%) with a history of CAM use for at least 3 months, while those with current use decreased to 62 (58.5%). Vitamins and minerals were the most commonly used, particularly vitamin D (97.1%) and calcium (47.7%). Both treatments were primarily prescribed (95.3%) rather than self-administered (24.3%). The main reasons for the use of CAM were to strengthen their health (48.6%) and relieve existing symptoms (28.0%). Conclusions: The use of CAM is common among patients with Thai CNS-IIDD. Further exploration of patient perspectives and preferences regarding CAM usage may contribute to a more comprehensive management approach for patients with CNS-IIDD.
