Abstract:
Ocrelizumab is a monoclonal anti-CD20 antibody approved for the treatment of both relapsing-remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS). Its increasing use for MS has been due in part to its efficacy, unique indication for PPMS, and convenient dosing, combined with a favorable side effect and risk profile. In this case report we describe two cases of meningitis developing within 1 year of initiating ocrelizumab therapy in patients with multiple sclerosis (MS).
Insights
Ocrelizumab, a multiple sclerosis (MS) treatment, may rarely cause meningitis. This case report details two instances of meningitis developing within one year of starting ocrelizumab therapy for MS.
Area of Science:
- Immunology
- Neurology
- Pharmacology
Background:
- Ocrelizumab is a targeted immunotherapy for multiple sclerosis (MS).
- It is an anti-CD20 monoclonal antibody used for relapsing-remitting MS (RRMS) and primary progressive MS (PPMS).
- Its efficacy, dosing, and safety profile have led to increased use in MS management.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
