A retrospective case-control study was performed to analyze hospital-acquired candidemia in HIV-positive patients. To understand the impact of Highly Active Antiretroviral Therapy (HAART) on the incidence of nosocomial candidemia, two time periods were compared: A (1992-1996) and B (1997-2001). 32 out of 38 (84%) cases of candidemia were hospital-related. A significant reduction in the incidence of all cases of hospital-acquired candidemia has been observed in the post-HAART in respect to pre-HAART period (0.09 episodes vs. 1.1 per 100/py). Multivariate analysis showed that the presence of central venous catheter was the only variable independently associated with the development of nosocomial candidemia. The overall mortality rate was 59%. Univariate analysis indicated three prognostic indicators: presence of concomitant opportunistic infections, isolation of non-albicans Candida species; neutropenia. Multivariate analysis of prognostic indicators showed that isolation of non-albicans Candida species is the only independent variable. Despite the use of HAART, this disease still represents a severe complication of advanced stage of AIDS.

Article Synopsis
- Invasive candidiasis (IC) caused by non-albicans Candida is on the rise globally, especially in pediatrics, but there is limited data on its characteristics and treatment responses in children.
- A study in a southern Brazilian children's hospital analyzed 123 non-duplicate Candida isolates from 2016 to 2021, finding a range of IC incidence between 0.88-1.55 cases per 1000 hospitalized patients and a mortality rate of 20.3%, with many cases occurring in patients under 13 months and linked to ICU admissions.
- The research noted that the predominant species were non-albicans Candida (70.8%), with most isolates producing biofilm, but there was no significant clonal

Background And Purpose: Emergence of fungi as a pathogenic threat presents a significant challenge to public health, notably in intensive care units (ICUs) and among immunocompromised patients. Various factors, including sepsis-induced barrier disruptions, immune system dysfunction, and extremes of age, contribute to increased susceptibility to fungal infections. Hospital practices, such as prolonged surgeries, broad-spectrum antibiotic use, and invasive procedures, further exacerbate the risk.
