Clinicoepidemiological study of adverse cutaneous drug reactions among immunocompromised children at a tertiary care hospital.

Introduction: Highly active antiretroviral therapy (HAART) is used to treat human immunodeficiency virus type 1 (HIV-1). Introduction of antiretroviral therapy (ART) has reduced the HIV/AIDS associated morbidity and mortality significantly. But 25% of all patients discontinue treatment because of adverse drug reactions (ADRs). Adverse cutaneous drug reactions (ACDR) are very common with ART regimens, which may range from mild pruritus, maculopapular rash to serious Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). ACDRs comprise 10%-30% of all reported ADRs.

Aims and objectives: To assess the different types of cutaneous adverse drug reactions in immunocompromised children of less than 18years.

Materials and methods: This is a retrospective record-based study, conducted at department of Dermatology, Venereology and Leprosy, Government Medical College (GMC)/Government General Hospital (GGH), Suryapet, Telangana, India. Data was collected from the records available at ART centre, from November 2018 to October 2021 GGH, Suryapet. All the HIV infected children ≤18 years who were on ART, were included in this study. Patients of more than 18 years and on other medications were excluded. Demographic data, socio economic status, vaccination status, height, weight, complete blood analysis, complete urine analysis, erythrocyte sedimentation rate, liver and renal function tests and CD4 counts were recorded before initiation of ART.

Results: A total of 330 children of less than 18 years were initiated for ART, at ART centre, Government General Hospital, Suraypet. Out of 330 children, 27.8% (92) children developed ACDRs. 58.7% (54) were males and 41.3% (38) were females. Maculopapular rash was seen in 65.2% (60) cases, urticaria was seen in 15.3% (14) cases, Steven Johnson Syndrome (SJS) was seen in 9.8% (9) cases, SJS/TEN overlap was seen in 6.5% (6) cases and toxic epidermal necrolysis (TEN) was seen in 3.2% (3) case. CD4 count was below 300 in 65.3% (60) cases above 300 in 34.7% (32) cases. Gap between initiation of the treatment and onset of reaction was less than one month in 65.3% (60) cases, and more than one month in 34.7% (32) cases.
