Live Imaging of Antifungal Activity by Human Primary Neutrophils and Monocytes in Response to A. fumigatus
Published on: April 19, 2017
Summary
Fluconazole shows efficacy comparable to amphotericin B for certain fungal infections like candidiasis and cryptococcal meningitis maintenance. Further research is needed for acute infections and specific patient groups.
Area of Science:
- Mycology
- Pharmacology
- Infectious Diseases
Background:
- Fluconazole is an antifungal medication used for oropharyngeal and esophageal candidiasis and cryptococcal meningitis.
- Amphotericin B is a traditional antifungal agent, but it has significant side effects.
- Comparative efficacy of fluconazole and amphotericin B requires further investigation for certain indications.
Purpose of the Study:
- To compare the efficacy of fluconazole with amphotericin B in treating fungal infections.
- To evaluate fluconazole's potential role in acute cryptococcal infections and systemic candidiasis.
- To identify patient populations, such as those with renal failure or organ transplants, where fluconazole's efficacy needs further study.
Main Methods:
- Clinical studies comparing fluconazole and amphotericin B were reviewed.
- Efficacy data for various fungal infections including candidiasis and cryptococcosis were analyzed.
- Safety profiles and side effects of both antifungal agents were considered.
Main Results:
- Fluconazole demonstrated equal or superior efficacy to amphotericin B in treating oral/esophageal candidiasis and for cryptococcal meningitis maintenance therapy.
- Amphotericin B remains the drug of choice for acute cryptococcal infections and systemic candidiasis.
- Amphotericin B's advantages include lack of acute renal failure, bone marrow depression, and corticosteroid suppression.
Conclusions:
- Fluconazole is a promising antifungal agent for specific indications.
- Further studies are necessary to establish fluconazole's efficacy in renal failure patients and organ transplant recipients.
- Amphotericin B continues to be the clinically proven choice for certain severe fungal infections due to its established efficacy and safety profile in specific contexts.

01:15Drug Dosage Regimen: Overview
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

01:24Drugs 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,...

01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
01:27Cryptococcal 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,...
01:20Candidiasis
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...
01:15Antifungal 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...
