title: A comparative study of CIDP in a cohort of HIV-infected and HIV-uninfected patients.
abstract: OBJECTIVE
  To investigate differences in clinical presentation, electrodiagnostic measures, CSF changes, and treatment outcome measures in HIV-infected and HIV-uninfected patients with chronic inflammatory demyelinating polyneuropathy (CIDP).
  
  
  METHODS
  A retrospective analysis of medical records of all patients meeting the European Federation of Neurology diagnostic criteria for idiopathic CIDP was performed in 2 neuromuscular units in Kwa-Zulu Natal between 2003 and 2015.
  
  
  RESULTS
  Eighty-four patients were included in the study; 39 were HIV-infected and 45 were HIV-uninfected. Among the HIV-infected patients, the majority were younger, were female, and had a monophasic progressive illness. Eighty-six percent (86%) were corticosteroid-responsive and 76% were in remission within 6-12 months requiring no further treatment. Among the HIV- uninfected patients, the majority were older, were male, and had a relapsing-remitting course. Twenty-seven percent (27%) were corticosteroid-responsive, 95% required combination therapy, and 33% were not in remission by 18 months on therapy.
  
  
  CONCLUSIONS
  This study shows that HIV-infected patients with CIDP were younger, were more often female, displayed a monophasic progressive course, were highly steroid-responsive, and went into remission within 12 months of corticosteroid initiation.
