Chronic disseminated candidiasis (CDC) is a form of Candida species infection observed primarily in patients with acute leukemia. To investigate possible genetic factors associated with CDC, we conducted a pilot study of 40 patients with both leukemia and CDC and 50 control patients with leukemia only. A common haplotype of the IL4 promoter (-1098T/-589C/-33C) was overrepresented in patients with CDC (P= .01; odds ratio [OR], 2.16), whereas another common haplotype (-1098T/-589T/-33T) appeared to be protective against CDC (P= .018; OR, 0.47). Genetic variants of IL4 could contribute to the development of CDC in patients with acute leukemia.

Chronic disseminated candidiasis is a serious fungal infection in immunocompromised patients, particularly those undergoing therapy for acute leukemia. Coordination between innate and adaptive immune system is critical to resistance or susceptibility to Candida infection. In order to investigate possible genetic contribution to chronic disseminated candidiasis of key molecules in the innate immune pathway, we performed a case control study using the candidate gene approach. Forty subjects with chronic disseminated candidiasis and 50 controls without chronic disseminated candidiasis but an underlying diagnosis of leukemia were enrolled in the Helsinki University Central Hospital during the period 1980-1998. Candidate genes were selected for analysis based upon the following criteria: a common polymorphism (>5% frequency) and existence a priori of clinical and biological data suggesting a role for the variant in the pathogenesis of chronic disseminated candidiasis. Six genes were selected from critical microbicidal and innate immune pathways, including three low-affinity Fcgamma receptors (FCGR2A, FCGR3A and FCGR3B), chitotriosidase (CHIT1), p22-phox NADPH oxidase (CYBA), and mannose binding lectin (MBL2). There was no statistically significant association of susceptibility to chronic disseminated candidiasis with the polymorphisms in this study. Common variants in the six studied genes most likely do not contribute to the risk for chronic disseminated candidiasis in patients with acute leukemia.

Chronic disseminated candidosis, often referred to as hepatosplenic candidosis (HSC), is an infection due to Candida spp. that mainly involves the liver and spleen. HSC occurs mostly in patients after profound and prolonged neutropenia, which is more often seen in patients with acute haematological malignancies. The incidence of HSC ranges from 3% to 29% in patients suffering from Acute Leukaemia. However, it is now seen less frequently with the widespread use of antifungal agents as prophylaxis or as preemptive therapy. Early and adequate diagnosis and treatment of HSC are crucial, as treatment delays can negatively affect the prognosis of the underlying condition. The pathogenesis is not well understood, but it is believed that it may be due to an unbalanced adaptive immune response that leads to an exacerbated inflammatory reaction, resulting in an Immune Reconstitution Inflammatory Syndrome. In this context, new therapeutic approaches such as the use of adjuvant high-dose corticosteroids have been shown beneficial. This article will focus on the clinical, diagnostic and therapeutic aspects of HSC and provide an accurate review of recent pathophysiological data.
