[Virus infections in man during immunodepression (author's transl)]

Area of Science:

• Virology
• Immunology
• Infectious Diseases

Context:

• Patients undergoing immunosuppressive therapy are at increased risk of opportunistic viral infections.
• Herpes viruses, particularly cytomegalovirus (CMV), are significant pathogens in this population.
• The precise contribution of viral reactivation to disease severity is debated.

Purpose:

• To review and analyze viral infections in immunocompromised patients.
• To discuss the mechanisms of viral infection, including primary infection and reinfection.
• To highlight the prevalence and impact of herpes viruses, especially CMV.

Summary:

• This review focuses on viral infections in patients receiving immunosuppressive treatment.
• Cytomegalovirus is identified as a primary concern, with herpes viruses being the most significant cause.
• The study examines different infection pathways: primary infection, exogenous reinfection, and endogenous reinfection, with the latter being most common for herpes viruses.

Impact:

• Provides insights into the pathogenesis of viral infections in immunosuppressed individuals.
• Informs clinical management strategies for preventing and treating viral complications.
• Highlights the importance of understanding viral reactivation in immunocompromised patients.
