Systemic antifungal drugs for invasive fungal infection in preterm infants
1Tayside Institute of Child Health, Ninewells Hospital and Medical School, Dundee, UK, DD1 9SY.
Background:
Invasive fungal infection is an increasingly common cause of mortality and morbidity in preterm infants. In addition to amphotericin B, a variety of newer antifungal drugs and drug preparations are available for treatment. There is a need to assess their relative merits.
Objectives:
In preterm infants with suspected or confirmed invasive fungal infection, does treatment with newer systemic antifungal drugs or drug preparations, versus conventional amphotericin B alone, reduce mortality and adverse neurodevelopmental outcomes?
Search Strategy:
We used the standard search strategy of the Cochrane Neonatal Review Group. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2003), MEDLINE (1966 - August 2003), EMBASE (1980 - August 2003), conference proceedings, and previous reviews.
Selection Criteria:
Randomised and quasi-randomised control trials comparing one antifungal agent or combination of agents with another in preterm infants with suspected or confirmed invasive fungal infection.
Data Collection And Analysis:
We extracted the data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author, and synthesis of data using relative risk and risk difference. The pre-specified outcomes were death prior to hospital discharge, longer term neurodevelopment, and adverse drug reactions resulting in discontinuation of therapy.
Main Results:
We identified only one small trial. This study compared the use of fluconazole with amphotericin B (5-Fluorocytosine added if fungal meningitis present). Three of 11 infants who were treated with fluconazole died and four of 10 infants who were treated with amphotericin B died : Relative risk: 0.68 (95% confidence interval 0.20, 2.33), Risk Difference -0.13 (95% confidence interval -0.53, 0.27) There were not any data on longer term outcomes.
Reviewer'S Conclusions:
From this one small study there are insufficient data to favour one antifungal agent or combination to reduce mortality and adverse neurodevelopmental outcomes in preterm infants with suspected or confirmed invasive fungal infection. A large randomised controlled trial is required to compare the newer antifungal preparations with conventional amphotericin B. Further research may also determine the relative convenience and cost effectiveness of the available drugs.
Insights
Limited data from one small trial show insufficient evidence to favor newer antifungal drugs over conventional amphotericin B for treating invasive fungal infections in preterm infants. Further research is needed.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Pharmacology
Background:
- Invasive fungal infections (IFIs) pose a significant threat to preterm infants, contributing to mortality and morbidity.
- While amphotericin B is a conventional treatment, newer antifungal agents and preparations are available.
- There is a clinical need to evaluate the comparative effectiveness of these antifungal treatments.
Purpose of the Study:
- To determine if newer systemic antifungal drugs or preparations reduce mortality and adverse neurodevelopmental outcomes in preterm infants with IFIs compared to conventional amphotericin B.
- To synthesize evidence from randomized and quasi-randomized controlled trials.
Main Methods:
- A systematic literature search was conducted using Cochrane Neonatal Review Group strategies, including CENTRAL, MEDLINE, and EMBASE.
- Included were randomized and quasi-randomized trials comparing antifungal agents in preterm infants with suspected or confirmed IFIs.
- Data extraction and quality assessment were performed independently, with outcomes including mortality, neurodevelopment, and adverse drug reactions.
Main Results:
- Only one small trial was identified, comparing fluconazole with amphotericin B (with or without 5-Fluorocytosine).
- Mortality rates were 3/11 with fluconazole and 4/10 with amphotericin B (Relative Risk: 0.68 [0.20, 2.33]).
- No data on longer-term neurodevelopmental outcomes were available.
Conclusions:
- Insufficient data exist from this single study to recommend newer antifungal agents over conventional amphotericin B for IFIs in preterm infants.
- A large randomized controlled trial is necessary to compare newer antifungal preparations with conventional amphotericin B.
- Further research should also investigate the convenience and cost-effectiveness of available antifungal drugs.
