Abstract

Insights

Topical 1% voriconazole and 5% natamycin are equally effective for treating fungal keratitis. Both treatments showed comparable resolution times and visual acuity gains in this pilot study.

Area of Science:

  • Ophthalmology
  • Mycology
  • Infectious Diseases

Background:

  • Fungal corneal ulcers require effective topical treatments.
  • Comparing novel antifungals to established therapies is crucial for clinical practice.

Purpose of the Study:

  • To evaluate the efficacy of topical 1% voriconazole compared to 5% natamycin for fungal keratitis.
  • To determine if voriconazole offers an advantage over natamycin as a primary treatment.

Main Methods:

  • Prospective, randomized pilot study.
  • 30 patients with proven fungal keratitis randomly assigned to 5% natamycin or 1% voriconazole.
  • Outcomes assessed included time to resolution and visual acuity over a minimum 10-week follow-up.

Main Results:

  • 29 out of 30 patients achieved complete ulcer resolution.
  • Resolution times (24.3 days vs. 27.2 days) and visual acuity gains (1.12 vs. 0.77 LogMAR) were comparable between groups (P > 0.05).
  • Aspergillus spp. and Curvularia spp. were the most common fungal isolates.

Conclusions:

  • Topical 1% voriconazole is safe and effective for primary fungal keratitis treatment.
  • Voriconazole demonstrated comparable efficacy to conventional natamycin.
  • No added benefit of voriconazole over natamycin was observed in this study.

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...
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...

Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents

In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy01:16

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
