Abstract

Introduction: Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) is an acquired immune-mediated peripheral neuropathy. This study was undertaken to describe the clinical and electrophysiological profile of patients with CIDP from a single centre.

Aims and Objectives: 1. To study the clinical and electrophysiological profile of patients with CIDP. 2. To study the effects of treatment and their outcomes in patients with CIDP through the inflammatory neuropathy cause and treatment (INCAT) scoring system and INCAT overall disability sum score (ODSS).

Materials and Methods: It is an ambispective study conducted between July 2017 and December 2019 in the Department of Neurology, Nizam’s Institute of Medical Sciences. A structured proforma and nerve conduction studies were done.

Results: The mean age was 41.32 years. Male: Female = 38:12. Twenty-four patients had a relapsing remitting course, 24 patients had a progressive course, and 2 had an acute onset of Guillain-Barre syndrome presentation. Typical CIDP was seen in 42 (84%) patients, 5(10%) patients had Multifocal acquired demyelinating sensory and motor neuropathy (MADSAM) variant, 2 patients had pure motor variant, 1 patient had pure sensory variant, and none of them showed distal acquired demyelinating symmetric (DADS) phenotype. Slow conduction velocity was the most common observation seen in 94% patients.

Conclusions: Typical CIDP was the most common phenotype, and none of the subjects had the DADS variant; thus, we can hypothesise that the prevalence of DADS in South India is less compared to the Western studies.

Key message: CIDP is an immune-mediated disorder with various phenotypes. Treatment should be tailored made depending upon the phenotype. This is one of the largest cohorts from a single centre in South India.
