Successful Treatment of Chronic Disseminated Candidiasis Complicated by Immune Reconstitution Inflammatory Syndrome in a Child With Acute Lymphocytic Leukemia.

Chronic disseminated candidiasis (CDC) is a severe form of disseminated fungal infection that commonly affects the liver, spleen, and kidneys. In rare cases, CDC can be further complicated by an excessive immune response known as immune reconstitution inflammatory syndrome (IRIS). This syndrome occurs during the phase of immune recovery and is characterized by a systemic inflammatory response and excessive release of cytokines. We present a case of a two-year-old female with a medical history of acute lymphocytic leukemia on chemotherapy. She was admitted with high fever refractory to conservative management that included broad-spectrum antimicrobials. Additionally, multiple skin lesions and a left-sided limp were noted. Whole-body imaging revealed multiple abscesses in the spleen, kidneys, scalp, and left lower limb. The culture of an aspirate material from skin lesions grew Candida tropicalis. Despite receiving appropriate antifungals, the patient showed no signs of improvement, leading to the diagnosis of CDC-induced IRIS. The patient was started on systemic corticosteroids, which resulted in rapid improvement in the patient's clinical status, resolution of fever, and significant reduction in inflammatory markers.
