Insights

This study reports a successful treatment of cryptococcal meningitis in an elderly patient using liposomal amphotericin B (L-AMB) and voriconazole (VRCZ). The combination therapy proved safe and effective, even with co-existing renal insufficiency.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Pharmacology

Background:

  • Cryptococcal meningitis is a serious opportunistic infection, particularly in immunocompromised individuals.
  • Corticosteroid use for conditions like microscopic polyangiitis can increase the risk of fungal infections.
  • Standard treatment guidelines aim to balance efficacy with minimizing drug-related toxicities, especially nephrotoxicity.

Observation:

  • An 81-year-old woman on corticosteroids presented with fever and altered consciousness, indicative of meningitis.
  • Cerebrospinal fluid analysis confirmed Cryptococcus neoformans infection, consistent with cryptococcal meningitis.
  • Neurological examination revealed disturbed consciousness and nuchal rigidity.

Findings:

  • Treatment with liposomal amphotericin B (L-AMB) led to clinical and cerebrospinal fluid (CSF) parameter improvements.
  • Addition of voriconazole (VRCZ) was necessary due to persistent cryptococcal antigen in CSF, leading to a further decrease in antigen titers.
  • The combined L-AMB and VRCZ regimen was well-tolerated, with no severe adverse events requiring treatment modification.

Implications:

  • This case suggests that the combination of L-AMB and VRCZ is a safe and effective treatment option for cryptococcal meningitis in elderly patients, including those with renal insufficiency.
  • The findings highlight a potentially valuable therapeutic strategy in a region where this specific combination has been rarely reported.
  • Successful management underscores the importance of tailored antifungal therapy in immunocompromised elderly patients.

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...
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
