ABSTRACT

Background: Seborrheic dermatitis is a chronic and relapsing skin disease, characterized by scales, inflammation and erythema, mainly on body areas rich in sebaceous glands, such as the scalp, face and chest.
Objective: To determine by methylene blue staining the presence of Malassezia spp on patients with HIV/AIDS and seborrheic dermatitis on the scalp, in order to determine if a correlation exists.
Materials and Methods: A prospective study done from January to August 2019, in which patients from the Infectious Diseases Clinic of the Dr. Manuel Gea González General Hospital and the Condesa Iztapalapa Specialty Clinic were included. Scale was taken by scraping with a sterile scalp blade from the scalp, with subsequent sweeping over an equally sterile slide.
Results: Two hundred four patients were studied, of which 187 (92%) were men and 17 (8%) were women. In their last laboratory results, 40% of the patients had a CD4+ lymphocyte count greater than 500, while 37% had 200-500 CD4+ lymphocytes and only 23% had less than 200 CD4+ lymphocytes. One hundred percent of the patients were positive for Malassezia spp on the scalp scale.
Conclusions: In the direct examination stained with methylene blue, Malassezia spp was present in 100% of the patients with seborrheic dermatitis, showing a strong relationship between the existence of yeast and that of dermatosis.
