ABSTRACT
Background Management of patients with multiple sclerosis (MS) and evidence of disease activity during treatment with cladribine tablets represents a challenging point. Objectives To report a patient with highly active multiple sclerosis (HAMS) who has been early switched from cladribine to alemtuzumab owing to tumultuous clinical and radiological activity Methods A single retrospective case report. Results. Treatment with alemtuzumab has led to a complete suppression of disease activity without any evidence of infections or acquired autoimmune diseases. Conclusion Our report suggests that an early switch from cladribine to alemtuzumab, may be safe and efficacious in selected HAMS cases.Copyright © 2022 The Authors
ABSTRACT
Background: Dimethyl fumarate (DMF) is an approved treatment for multiple sclerosis (MS). Due to its efficacy and safety profile, DMF is the most prescribed oral medication for relapsing remitting (RR) MS. Given the long-term course of treatment with DMF in MS, continuous surveillance of opportunistic infections is fundamental. Case presentation: We report the occurrence of facial herpes zoster (HZ) associated with MS disease reactivation in a person with RRMS after 6 years of DMF therapy. Case report: A 44-year-old woman with RRMS developed right temple pain and blisters over the right cheek, suggestive of facial HZ. A normal lymphocyte count with however relatively lower proportions of CD8+ T cells and higher percentages of natural killer cells were detected in blood. The patient failed oral treatment and required hospitalization for intravenous acyclovir. She eventually developed symptoms of an MS exacerbation featured by lower extremities weakness and urinary retention. Conclusion(s): Our case highlights the importance of counseling patients on the possibility of HZ reactivation even in the setting of a normal lymphocyte count, the risk of MS exacerbation possibly associated with HZ occurrence and the importance of timely vaccination.Copyright © 2022
