Quality of life in hereditary neuropathy with liability to pressure palsies is as impaired as in Charcot-Marie-Tooth disease type 1A.

To date, only one study assessed quality of life (QoL) in patients with hereditary neuropathy with liability to pressure palsies (HNPP). We aimed to fill in this gap by investigating QoL in a cohort of patients with HNPP compared to Charcot-Marie-Tooth type 1A (CMT1A) patients, as well as to analyze sociodemographic and clinical features associated with QoL in HNPP. Eighteen genetically confirmed HNPP patients were age-and gender-matched with 18 CMT1A patients. SF-36 questionnaire was used to assess QoL. Medical Research Council (MRC) Sum Score, CMT Neuropathy Score (CMTNS), Overall Neuropathy Limitation Scale Score (ONLS), Falls Efficacy Score (FES), Visual Analog Pain Scale, Beck Depression Inventory (BDI) and Fatigue Severity Scale (FSS) were also used in our study. Although HNPP patients were less clinically impaired, no difference was observed in these two cohorts regarding SF-36 scores. Worse QoL in HNPP patients was associated with lower education (p < 0.01), physical work (p < 0.05), higher number of clinically affected nerves during the disease course (p < 0.01), worse MRC-SS score (p < 0.01), worse ONLS score (p < 0.01), and with more severe pain (p < 0.01), depression (p < 0.01), and fatigue (p < 0.01). Worse pain at the moment of testing appeared as a significant independent predictor of worse QoL in HNPP patients (β = - 0.93, p < 0.001). QoL was similarly impaired in patients with HNPP and patients with CMT1A. We identified different factors associated with QoL in HNPP, and many of these factors are amenable to treatment which is of special interest in these still incurable disease.
