[Current Concepts of Human Microsporidiosis]

Area of Science:

• Medical Parasitology
• Infectious Diseases
• Immunocompromised Host Pathologies

Background:

• Microsporidia are ubiquitous, opportunistic, fungi-related obligate intracellular parasites.
• Microsporidiosis commonly affects immunocompromised patients, including those with AIDS and organ transplant recipients.
• These parasites are significant causes of diarrhea in HIV-infected individuals, alongside Cryptosporidium and Cytomegalovirus.

Purpose of the Study:

• To provide a comprehensive overview of microsporidiosis.
• To consolidate current knowledge on the etiology, pathogenesis, epidemiology, clinical presentation, diagnosis, and treatment of microsporidiosis.

Main Methods:

• Literature review of existing data on microsporidiosis.
• Synthesis of information regarding the multifaceted aspects of the disease.

Main Results:

• Microsporidiosis presents with diverse clinical manifestations depending on the affected organ system.
• Intestinal microsporidiosis is most common, but ocular, pulmonary, muscular, and neurological involvements are also documented.
• Microsporidia pose a significant health challenge, particularly in vulnerable populations.

Conclusions:

• Microsporidiosis is a complex opportunistic infection requiring thorough understanding for effective management.
• Early diagnosis and appropriate treatment are crucial for improving outcomes in affected patients.
• Further research is needed to fully elucidate all aspects of microsporidiosis and develop targeted therapies.
