Low body mass index can be associated with the risk and poor outcomes of neuromyelitis optica with aquaporin-4 immunoglobulin G in women

Introduction

Neuromyelitis optica spectrum disorder with aquaporin-4 immunoglobulin G (NMOSD-AQP4) is an inflammatory disease of the central nervous system (CNS). Recent studies have demonstrated that body mass index (BMI) can be associated with the risk and/or outcomes of diverse inflammatory diseases, such as rheumatoid arthritis (RA), psoriasis, Hashimoto's thyroiditis and multiple sclerosis (MS). However, the clinical implication of BMI in NMOSD-AQP4 is still unknown.

Materials and methodsPatients

A total of 157 patients with NMOSD-AQP4 who had their first episodes between 1982 and 2016, from six nationwide tertiary referral hospitals, were finally included (see figure 1 in the online ). Patients were tested for antiaquaporin-4 (AQP4) antibody using either the fluorescence-activated cell sorting assay or cell-based assay.1 In the NMOSD-AQP4 group, BMI measured within 1 month of the first symptom of NMOSD-AQP4 and before any steroid treatment, immune suppressant, or immune modifying treatment (BMI_naive) and the lowest BMI measured within...
