Introduction: Fingolimod is the first oral immunomodulatory treatment used as secondary care therapy in the treatment of multiple sclerosis for the last 10 years. The objective of our study is to reveal the experiences of the first generic fingolimod active ingredient treatment in different centers across Turkey. Method: The first generic fingolimod efficacy and safety data of patients followed-up in 29 different clinical multiple sclerosis units in Turkey were analyzed retrospectively. Data regarding efficacy and safety of the patients were transferred to the data system both before the treatment and on the 6th, 12th and 24th month following the treatment. The data were analyzed using the IBM SPSS 20.00. P value of <0.05 was considered to be statistically significant. Results: A total of 508 multiple sclerosis patients, 331 of whom were women, were included in the study. Upon comparing the Expanded Disability Status values before and after the treatment, a significant decrease was observed, especially at month 6 and thereafter. Since bradycardia occurred in 11 of the patients (2.3%), the first dose had to be longer than 6 hours. During the observation of the first dose, no issues that could prevent the use of the drug occured. Side effects were seen in 49 (10.3%) patients during the course of fingolimod treatment. Respectively, the most frequent side effects were bradycardia, hypotension, headache, dizziness and tachycardia. Conclusion: The observed results regarding efficacy and safety were similar to clinical trial data in the literature and real life data in terms of the first equivalent with fingolimod active ingredient.

Clinical, Demographic, and Radiological Characteristics of Patients Demonstrating Antibodies Against Myelin Oligodendrocyte Glycoprotein
(Galenos Publ House, 2024) Koc, Sumeyye; Sen, Sedat; Terzi, Yuksel; Kizilay, Ferah; Demir, Serkan; Aksoy, Durdane Bekar; Terzi, Murat
Background: Optic neuritis, myelitis, and neuromyelitis optica spectrum disorder (NMOSD) have been associated with antibodies against myelin oligodendrocyte glycoprotein-immunoglobulin G (anti-MOG-IgG). Furthermore, patients with radiological and demographic features atypical for multiple sclerosis (MS) with optic neuritis and myelitis also demonstrate antibodies against aquaporin-4 and anti-MOG-IgG. However, data on the diagnosis, treatment, follow-up, and prognosis in patients with anti-MOG-IgG are limited. Aims: To evaluate the clinical, radiological, and demographic characteristics of patients with anti-MOG-IgG. Study Design: Multicenter, retrospective, observational study. Methods: Patients with blood samples demonstrating anti-MOG-IgG that had been evaluated at the Neuroimmunology laboratory at Ondokuz May & imath;s University's Faculty of Medicine were included in the study. Results: Of the 104 patients with anti-MOG-IgG, 56.7% were women and43.3% were men. Approximately 2.4% of the patients were diagnosed with MS, 15.8% with acute disseminated encephalomyelitis (ADEM), 39.4% with NMOSD, 31.3% with isolated optic neuritis, and 11.1% with isolated myelitis. Approximately 53.1% of patients with spinal involvement at clinical onset demonstrated a clinical course of NMOSD. Thereafter, 8.8% of these patients demonstrated a clinical course similar to MS and ADEM, and 28.1% demonstrated a clinical course of isolated myelitis. The response to acute attack treatment was lower and the disability was higher in patients aged > 40 years than patients aged < 40 years at clinical onset. Oligoclonal band was detected in 15.5% of the patients. Conclusion: For patients with NMOSD and without anti-NMO antibodies, the diagnosis is supported by the presence of anti-MOG-IgG. Furthermore, advanced age at clinical onset, Expanded Disability Status Scale (EDSS) score at clinical onset, spinal cord involvement, and number of attacks may be negative prognostic factors in patients with anti-MOG-IgG.
Comparative Efficacy of Rituximab Versus Azathioprine in the Treatment of MOG Antibody-Associated Disease (MOGAD)
(Elsevier, 2025) Sen, Sedat; Kurtuncu, Murat; Demir, Serkan; Gunduz, Tuncay; Demirel, Ezgi; Tutuncu, Melih; Tuncer, Asli
Background: Azathioprine (AZA) and rituximab (RTX) are frequently used drugs in the treatment of Myelin Oligodendrocyte Glycoprotein Associated Disease (MOGAD). Objectives: The aim of this study was to evaluate the efficacy and safety data of AZA and RTX treatments in MOGAD. Methods: Patients diagnosed according to the 2023 MOGAD diagnostic criteria and receiving AZA or RTX treatment were included in the study. Results: In 142 patients included in the study, the female/male value was 1.2. The rate of OCB positivity in MOGAD patients was 22.6 %. Patients on RTX had higher EDSS values than patients on AZA. However, the RTX group demonstrated a more pronounced improvement in disability, reflected by a greater negative trend in the Delta EDSS values. The attack-free rate was 78 % in the RTX group and 68 % in the AZA group during their treatment period. Both groups had no difference in the time of the first attack. The main factor affecting the time to first attack was having a higher EDSS at the time of treatment initiation. The survival analysis found that EDSS scores improved significantly in patients treated with RTX. Conclusion: Although survival analyses for both treatments appear to be similar, using RTX provides better EDSS scores.
