Fungal Infection in Patients in Intensive Care Units

Predictors of fungal infection in non-neutropenic patients in intensive care units and the aim of the study is To evaluate the frequency of fungal infection in non-neutropenic patients in Intensive Care Units. To evaluate the risk factors of fungal infection in these patients.

The incidence of candidemia in the overall population ranges from 1.7 to 10 episodes per 100,000 inhabitants and Candida is one of the ten leading causes of bloodstream infections in developed countries. An estimated 33-55% of all episodes of candidemia occur in intensive care units (ICU) and are associated with mortality rates ranging from 5% to 71%. Candida fungemia may have an endogenous or an exogenous origin, and in recent years a growing proportion of episodes of candidemia have been caused by Candida species other than albicans. The most important independent conditions predisposing to candidemia in ICU patients include prior abdominal surgery, intravascular catheters, acute renal failure, parenteral nutrition, broad-spectrum antibiotics, a prolonged ICU stay, the use of corticosteroids and mucosal colonization with Candida. In recent years, several studies have shown that ICU patients with mucosal Candida colonization, particularly if multifocal, are at a higher risk for invasive candidiasis, and that colonization selects a population amenable to antifungal prophylaxis or empirical therapy. Candidemia in ICUs is associated with a con- siderable increase in hospital costs and length of hospital stay. Invasive fungal infection (IFI) is a grave infection associated with serious effects in patients with chronic diseases including liver cirrhosis. The diagnosis of IFI re- quires histopathological evidence of tissue invasion, or isolation in blood cultures, or isolation from a normally sterile body fluid or site, with samples collected intra-op- eratively or by percutaneous needle aspiration. Awareness of IFI has been increased in clinical practice with the increased survival of patients in immunocompromised states. Such infections are associated with a high morbidity and significant mortality, requiring early diagnosis and appropriate treatment, but also optimal prophylaxis in patients at high risk. Globally, several studies had assessed fungal infections in non-neutropenic patients, however, to our knowledge, searching for fungal infections in these patients are un- derestimated in our locality.
