    Abstract:
    BACKGROUND: Patients with acute myeloid leukemia (AML) are at risk of hepatosplenic candidiasis (HSC). HSC is often associated with prolonged fever and difficulty in definitive clinical diagnosis. We aimed to explore the incidence, clinical features, image findings and outcomes of HSC among patients with AML in a tertiary hospital, Taiwan. METHODS: We did a chart review of patient data in our institute from 2009 to 2012. The diagnosis of HSC was based on risk factors, febrile symptoms and image findings. RESULTS: Two hundred and ninety-two patients with AML were analyzed. In total, 1051 chemotherapy sessions were administered. Eleven patients (4 males and 7 females) experienced HSC (incidence 3.8%, 95% conference interval 2.11-6.72%). Among those with HSC, the median age was 62. Eight patients developed HSC following induction or re-induction chemotherapies. Three developed HSC following consolidation chemotherapies. The median duration of severe neutropenia was 25 days (range 10-142). In all patients with HSC, multiple hypodense lesions were found in the involved organs by computed tomography scans. Lesions consistent with HSC could be identified by ultrasound in 5 out of 6 patients. Other than liver and spleen, lung was frequently (7 cases) and kidney occasionally (3 cases) involved. Four patients died within 90 days. Prolonged neutropenia was associated with mortality. CONCLUSION: HSC occurred more often during induction or re-induction periods. Lungs are commonly involved and pleural effusion was frequently seen in CT scans. Pleural effusion may suggest more serious infections but its clinical relevance should be investigated in large-scale studies. Prolonged neutropenia is the only prognostic factor. Prophylaxis should be considered. In the absence of prophylaxis, we advise early image studies and prompt antifungal treatment in patients at risk for HSC.
