Profile of neonatal candidiasis in tertiary neonatal intensive care unit: A report from a developing country

Systemic candidiasis is an important nosocomial infection in neonatal intensive care units. The objective of this study was to identify the change in the profile of neonatal candidiasis in a tertiary neonatal intensive care unit (NICU) in eastern India in recent times.

It was a retrospective review of case records from 2014 to 2019 from a tertiary NICU of eastern India. Data of the fungal sepsis, demographic details, risk factors of fungal sepsis and mortality were collected from 103 neonates.

One hundred and three neonates had blood culture positive for fungal species of which 91 (88.3%) infants weighed ≥1500 g and 66 (64%) infants were term. There was significant higher incidence of candidiasis among outborn (Relative risk of outborn 18.84, 95% CI 10.74-33.05). Prolonged antibiotic usage (>14 days), meropenem usage (>5 days), central catheterization (>5 days), invasive mechanical ventilation (>5 days), surgical intervention were found in 64 (62.1%), 46 (44.6%), 31(30.0%), 40 (38.8%) and 39 (37.8%) infants. Non albicans candida (NAC) was isolated as the predominant species (82/103, 79.6%). Resistance to both of fluconazole and amphotericin B were found in 19 (18.4%) babies. Presence of NAC infection and resistance to both amphotericin B and fluconazole were independent predictors of candida associated mortality in NICU.

Neonatal candidiasis is found among outborn infants with higher birth weight and gestational age. NAC species are predominant organisms with resistance to common antifungal drugs.
