Abstract
Background and Aims
The risk of fungal bloodstream infection (BSI) and accompanying mortality in neonates varies widely in between centres depending on the region, the population characteristics and the risk factors.
Methods
This chart review of neonatal cases with fungal BSI admitted in a tertiary care teaching hospital in North India aimed to comprehensively investigate the epidemiology, profile of fungal species (and their susceptibility to various antifungal agents), risk factors, clinical profile and outcomes in these neonates. The study spanned over a one-year period, from September 2022 to August 2023, included all symptomatic neonates with positive blood cultures for fungal pathogen.
Results
Over one year, 24 out of 1,174 neonates at risk were diagnosed with fungal BSI, with a cumulative risk of 2.0 per 100 neonates. A peak in cases occurred in February. Candida pelliculosa was the predominant species (75% of isolates), while Candida albicans constituted 4.2%. Most isolates were sensitive to fluconazole, except for some fluconazole-resistant Candida pelliculosa (5.5%) and Candida tropicalis (25.0%), which remained susceptible to amphotericin-B and voriconazole. Around 60% of neonates were preterm, 40% had very low birth weight and 37% were small for gestational age. Nearly all had received prior broad-spectrum antibiotics, with 92% receiving prolonged courses over five days. Respiratory support, including intubation and mechanical ventilation, was used in 83% before onset of fungal sepsis. Intriguingly, all neonates had some invasive device in place for more than seven days. Mortality rate of 25% was observed, with preterm birth and gastrointestinal anomalies contributing to adverse outcomes.
Conclusions
This study confirms the ongoing shift in trend from albicans to non-albicans Candida infections in our region as well. A seasonal peak of fungal sepsis noted in the month of February hinted at potential seasonal variation or lapses in infection control practices during colder months. The analysis of trends in fungal BSI might hold a significance within neonatal intensive care units (NICUs) for the prompt detection of outbreaks. Simultaneously, understanding and analysing risk factors associated with fungal BSI are essential for targeted prevention.
