Epidemiology and demographics of cutaneous lupus erythematosus in Colombia between 2015 and 2019

Abstract

Cutaneous lupus erythematosus (CLE) is classified into three groups-acute, subacute, and chronic-based on clinical and histopathological characteristics. The risk of systemic manifestations varies among these groups. There are few studies on CLE epidemiology. For this reason, this paper aims to describe CLE prevalence and demographics in Colombia between 2015 and 2019. This descriptive, cross-sectional study used the international classification of diseases, tenth revision, for CLE subtypes, utilizing official data from the Colombian Ministry of Health. In people older than 19 years, 26,356 CLE cases were registered, yielding a prevalence of 76 cases per 100,000 population. CLE was more frequent in females, at a 5:1 ratio compared to males. The most common clinical presentation was discoid lupus erythematosus, in 45% of cases. The majority of cases occurred in people between 55 and 59 years old. This is the first study that describes CLE demographics in adults in Colombia. Findings regarding clinical subtypes and female predominance are consistent with those in the medical literature.
