Abstract
BACKGROUND Erythroderma is a clinical entity that may cause severe systemic manifestations. The difficulty with erythroderma lies in finding the underlying aetiology. It is imperative to demonstrate precise aetiology whenever possible so that distinct therapy may be initiated. At times, despite finding the aetiology, relapses constitute a great menace. The purpose of our study was to assess the clinical profile and aetiology of erythroderma. Besides, the study also illustrated factors leading to relapses; such studies are rare in literature. METHODS This hospital-based, cross-sectional study included 88 patients of erythroderma of either sex and age more than 18 years; their clinical, laboratory, histopathological findings, treatment and outcome were studied. RESULTS The mean age of onset was 47.3 ± 12.35 years with the male to female ratio being 2.38:1. The most common cause of erythroderma was pre-existing dermatoses (67 %) followed by drugs (10.2 %), infections (3.4 %), malignancies (4.54 %), and idiopathic (14.7 %). Psoriasis was the predominant aetiology (45.4 %) among the pre-existing dermatoses with a maximum number of relapses (P = 0.02). Psoriasis was significantly associated with pruritus (P = 0.001), subungual hyperkeratosis (P = 0.0001), palmoplantar keratoderma (P = 0.001). Clinicohistological association was found in 64.6 % of cases. Mortality was seen in 6.8 % of cases. CONCLUSIONS As in previous studies, pre-existing dermatoses were the most common causes in our study; albeit, a special emphasis on factors leading to relapses was given to prevent further episodes. The most common factor of relapse was uncontrolled comorbid disorders (diabetes and hypertension) followed by medication nonadherence. Hence, our study suggests a need for more effective comorbidity management and creating awareness regarding judicial use of drugs which can go far in preventing mortality and morbidity.
