Simian adenovirus infection — Clinical Guidelines

Overview

Simian adenovirus infections are rare but can cause severe systemic illness, particularly in immunocompromised individuals and transplant recipients, manifesting with multi-organ failure and disseminated disease 1 3.

Diagnosis

Clinical Presentation: Fulminant sepsis, multiple organ failure, and disseminated infection 1 3.

Laboratory Tests: PCR for viral DNA in blood, urine, respiratory aspirates, and stool samples 3.

Epidemiological Context: Consider in outbreaks within specialized healthcare settings like hematology units 2.

Management

First-Line Treatment: Cidofovir for severe cases in immunocompetent patients, though use is limited due to nephrotoxicity 1.

Supportive Care: Extracorporeal membrane oxygenation (ECMO) for respiratory and circulatory support in severe cases 1.

Monitoring: Close monitoring of organ function and potential nephrotoxicity with cidofovir use 1.

Special Populations

Immunocompromised Patients: Higher risk of severe disseminated infection requiring aggressive management 1 3.

Pediatrics: Susceptibility to fulminant hepatic failure post-transplant 3.

Key Recommendations

Consider Cidofovir for Severe Cases in Immunocompetent Patients with close monitoring for nephrotoxicity (Evidence: Weak 1).

Utilize PCR for Early and Accurate Diagnosis of disseminated adenovirus infections across multiple body fluids (Evidence: Moderate 3).

Implement Strict Infection Control Measures in specialized units like hematology settings to prevent outbreaks (Evidence: Expert opinion 2).
