Insights

A rare fungal infection, cutaneous alternariosis, presented with unusual skin lesions in an immunosuppressed patient. Treatment with liposomal amphotericin B effectively resolved a severe necrotic ulcer unresponsive to itraconazole.

Area of Science:

  • Mycology
  • Dermatology
  • Infectious Diseases

Background:

  • Cutaneous alternariosis is a rare fungal infection.
  • Immunosuppression increases susceptibility to opportunistic fungal infections.
  • Fungal skin infections can manifest with diverse and severe clinical presentations.

Observation:

  • An immunosuppressed patient developed unusual papular, nodular, and verrucous skin lesions on the forearms.
  • Despite six months of oral itraconazole treatment, a large, progressive, necrotic ulcer developed on the patient's leg.

Findings:

  • The patient's cutaneous alternariosis was refractory to oral itraconazole therapy.
  • Intravenous liposomal amphotericin B (750 mg total dose) resulted in excellent clinical improvement.

Implications:

  • Liposomal amphotericin B is an effective treatment option for severe cutaneous alternariosis in immunosuppressed individuals.
  • Early diagnosis and appropriate antifungal therapy are crucial for managing invasive fungal infections.
  • This case highlights the importance of considering unusual presentations of fungal infections in immunocompromised 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,...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
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...

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
