Chronic Disseminated Candidiasis in Children and the Role of Corticosteroids Therapy.

Abstract

Little is known about chronic disseminated candidiasis (CDC) in children. This study was done to describe the epidemiology, risk factors and outcome of CDC in children managed at Sultan Qaboos University Hospital (SQUH), Oman, and to describe the role of corticosteroids in the management of immune reconstitution inflammatory syndrome (IRIS) complicating CDC. We retrospectively reported demographic, clinical and laboratory data of all children managed in our center for CDC between January 2013 and December 2021. In addition, we discuss the available literature on the role of corticosteroids for management of CDC-related IRIS in children since 2005. Between January 2013 and December 2021, 36 immunocompromised children were diagnosed with invasive fungal infection at our center, of whom 6 had CDC (all with acute leukemia). Their median age was 5.75 years. Prolonged fever despite broad-spectrum antibiotics (6/6) followed by skin rash (4/6) were the most common clinical features of CDC. Four children grew Candida tropicalis from blood or skin. CDC-related IRIS was documented in 5 children (83%) and 2 received corticosteroids. Our literature review revealed that 28 children were managed with corticosteroids for CDC-related IRIS since 2005. The majority of these children had defervescence of fever within 48 hours. Prednisolone of 1-2 mg/kg/day for 2-6 weeks was the most common regimen used. No major side effects reported in these patients. CDC is more common in children with acute leukemia and CDC-related IRIS is not uncommon. Corticosteroid therapy looks effective and safe as adjunctive therapy for CDC-related IRIS.
