Abstract
INTRODUCTION: Lysis syndrome is a constellation of metabolic disorders usually seen after the initiation of chemotherapy for rapidly proliferating malignancies (tumor lysis syndrome). Reported herein is a tumor lysis-like syndrome after the initiation of anti-infective therapy for visceral leishmaniasis. PATIENTS AND METHODS: Ten consecutive patients with visceral leishmaniasis were administered liposomal amphotericin B. Levels of serum uric acid, phosphate, creatinine, blood urea nitrogen, potassium, calcium, and magnesium were evaluated prior to as well as 4 and 30 days following the initiation of treatment. RESULTS: During the 4th post-treatment day significant increases in the levels of serum uric acid, phosphate, creatinine, and blood urea nitrogen were seen, while the levels of calcium, potassium, and magnesium were not significantly altered. Patients were treated by hydration, urine alkalization, and administration of allopurinol as needed. A recovery of metabolic abnormalities was recorded 1 month later, although some patients had evidence of residual injury. CONCLUSION: A lysis syndrome may complicate the treatment of visceral leishmaniasis. Awareness of this complication can lead to the initiation of prophylactic treatment as well as to early recognition and management of this syndrome in susceptible patients.

Reported herein is a tumor lysis-like syndrome after the initiation of anti-infective therapy for visceral leishmaniasis. PATIENTS AND METHODS: Ten consecutive patients with visceral leishmaniasis were administered liposomal amphotericin B. Levels of serum uric acid, phosphate, creatinine, blood ureanitrogen, potassium, calcium, and magnesium were evaluated prior to as well as 4 and 30 days following the initiation of treatment. RESULTS: During the 4th post-treatment day significant increases in the levels of serum uric acid, phosphate, creatinine, and blood ureanitrogen were seen, while the levels of calcium, potassium, and magnesium were not significantly altered.
