Insights
Pediatric-onset multiple sclerosis (POMS) in Kuwait predominantly affects females and often presents with brainstem/cerebellar symptoms. Many POMS patients maintain a relapsing phenotype, with disease breakthrough common on platform therapies.
Area of Science:
- Neurology
- Immunology
- Pediatrics
Background:
- Limited epidemiological data exists for pediatric-onset multiple sclerosis (POMS) in the Middle East.
- Understanding POMS characteristics is crucial for effective management in this region.
Purpose of the Study:
- To investigate the demographic and clinical features of POMS in Kuwait.
- To provide insights into disease presentation, phenotype, and treatment response in a Middle Eastern cohort.
Main Methods:
- Retrospective study of 249 patients with POMS (onset < 18 years) meeting International Pediatric MS Study Group criteria.
- Analysis of demographic data, clinical presentation, disease phenotype, and treatment history.
Main Results:
- 70.3% of POMS patients were female, with a mean age at onset of 15.06 years.
- Brainstem/cerebellar (34.9%), spinal (29.3%), and visual pathway (27.3%) symptoms were common initial presentations.
- 83.5% maintained a relapsing-remitting phenotype; 36.1% experienced disease breakthrough on platform therapies.
Conclusions:
- POMS in Kuwait primarily affects females and often presents with neurological symptoms affecting the brainstem, cerebellum, or spinal cord.
- The majority of POMS patients exhibit a relapsing-remitting course, and disease breakthrough is a frequent challenge, particularly with initial platform therapies.
Background:
Epidemiological data of pediatric-onset multiple sclerosis (POMS) in the Middle East is limited.
Objective:
To determine the demographic and clinical characteristics of POMS in Kuwait.
Methods:
A retrospective study was conducted to assess the clinical characteristics of multiple sclerosis (MS) patients who disease onset started at age < 18 years and fulfilled the International Pediatric MS Study Group (IPMSSG) criteria for MS.
Results:
Of 249 POMS who were assessed, 70.3 % were female. The mean age at onset was 15.06 +11.78 years. Brainstem / cerebellar manifestation (34.9 %) were the most frequent presentation at onset of disease, followed by spinal (29.3 %) and visual pathway (27.3 %) symptoms. At the last follow-up visits, most of the patients (83.5 %) remained in a relapsing-remitting phenotype. The annual relapse rate (ARR) was 0.18 throughout the first 2 years while on treatment. At the baseline visit, the 51.4 % of the cohort-initiated platform therapies. Breakthrough disease (36.1 %) and adverse events (9.6 %) were the most common indications to escalate or switch to other disease-modifying drugs (DMTs).
Conclusion:
Most POMS patients continued to be in a relapsing phenotype in our longitudinal study. Disease breakthrough is common in POMS especially when using platform therapies.
