Atopic dermatitis in adults from sub-Saharan Africa: epidemiological and clinical patterns, severity, and quality of life
Background: Atopic dermatitis (AD) is a chronic and recurrent inflammatory dermatitis often associated with other atopic manifestations, such as asthma and allergic rhinitis. This study aimed to determine the epidemiological and clinical aspects of AD and to assess the quality of life (QoL) of patients suffering from AD in our setting. Materials and Methods: This was a cross-sectional study conducted from February through April 2017 in seven hospitals in Cameroon. The study included patients above 18 who presented themselves to a dermatology consultation, were diagnosed with AD, and gave their consent. To assess the severity of AD and evaluate the QoL of the patients, standardized scales, such as SCORAD and QoLIAD, were employed. Results: The study enrolled 46 patients between 18 and 69 years of age with a mean age of 31 ± 12 years and the prevalence of AD at 1.5%. Most of the participants were females, with a sex ratio of 0.4:1, living in urban areas (93.5%). Food (34.8%) and cosmetic products (21.7%) were found as the main risk factors in the occurrence of AD. Upon physical examination, the upper and lower limbs were found to be the most affected in 84.8% and 54.3% of cases, respectively; in addition to cutaneous xerosis (45.7%), lichenification (43.5%), and excoriations (37%). Of the 46 patients, 9 (20%) had severe AD, 32 (70%) had moderate AD, and 5 (10%) had mild AD. QoL was impaired in 43 of the 46 patients (93.5%). Conclusion: Atopic dermatitis is a pathology that impacts the QoL of adults. A QoL assessment is, therefore, an important step in the management of AD.
