Introduction: Corticosteroid therapy is widely used in dermatology for treating various conditions. In France, the cost of corticosteroid treatment varies, and in Mali, a significant prevalence of corticosteroid-treated diseases has been reported. Given the prolonged treatment duration often required, understanding the cost implications in resource-limited settings is crucial.Patients and methods: This descriptive cross-sectional study took place at the dermatology department of the University Hospital Center of Dermatology in Bamako. Data were prospectively collected from patients undergoing corticosteroid therapy over one year. Variables included sociodemographic data, clinical information, and medication costs.Results: During the study period, 24 cases of dermatoses treated with corticosteroids were identified among 125 hospitalized patients, representing a prevalence of 19.2%. Most patients were women (58.3%), with an average age of 37.5 years. Lichen planus (54.2%) and pemphigus (37.5%) were the most common pathologies. Many patients had extensive lesions before treatment, but the majority responded well to corticosteroids.Discussion: Despite study limitations, such as its descriptive nature, it provided valuable insights into the economic evaluation of long-term corticosteroid therapy. The predominance of women, the age distribution, and the prevalence of specific dermatoses were highlighted. The study also revealed the substantial financial burden of corticosteroid treatment, primarily driven by direct costs.Conclusion: The study underscores the financial challenges associated with long-term corticosteroid therapy in dermatology in Mali. The high costs adversely affect patients and their families, especially considering the socioeconomic status of many patients. Moreover, the findings emphasize the importance of comprehensive care strategies and the need for accessible healthcare solutions to address these challenges effectively.
