Insights

Antifungal prophylaxis with oral nystatin significantly reduced invasive fungal infections in premature infants. This study found lower infection rates in neonatal units using nystatin compared to those not using it.

Area of Science:

  • Neonatal Medicine
  • Infectious Diseases
  • Pharmacology

Background:

  • Neonatal fungal infections pose a risk, influencing the need for antifungal prophylaxis.
  • The incidence of these infections is a key factor in determining the value of prophylactic treatments.

Purpose of the Study:

  • To compare the incidence of fungal infections in neonatal units with and without oral nystatin prophylaxis.
  • To evaluate the effectiveness of antifungal prophylaxis in preventing neonatal fungal infections.

Main Methods:

  • A prospective, multi-centre surveillance study was conducted from 1993 to 2006.
  • Invasive fungal infections were monitored in infants weighing less than 1500 grams birth weight in Australian and New Zealand neonatal units.
  • Infections were defined by positive blood or cerebrospinal fluid cultures.

Main Results:

  • The overall incidence of invasive fungal infection was 0.80% in infants <1500 g.
  • Units using oral nystatin prophylaxis had a significantly lower incidence (0.54%) compared to units with no prophylaxis (1.23%) (p<0.001).
  • For infants <1000 g, nystatin prophylaxis was associated with a lower incidence (1.23%) versus no prophylaxis (2.67%) (p<0.001).

Conclusions:

  • Neonatal fungal infection incidence was low in Australia and New Zealand.
  • Oral nystatin prophylaxis was linked to a statistically significant reduction in fungal infection rates compared to no prophylaxis.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
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,...
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...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
