Abstract

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.

Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Intrauterine Drug Delivery Systems

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Antiprotozoal Agents

Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
