Abstract:
Although cytomegalovirus (CMV) pulmonary involvement after solid organ transplantation is infrequently seen nowadays, CMV pneumonitis is still a potential lethal complication. Introduction of the pp65 antigenemia assay enabled early and rapid diagnosis of CMV viremia in transplant patients prior to symptoms. Also, in asymptomatic patients with CMV viremia, a decreased pulmonary diffusion capacity could be demonstrated. In this review, we discuss clinical and subclinical pulmonary involvement of CMV infection in the immunocompromised host with an emphasis on transplant recipients. The clinical course, diagnosis, therapy, prophylaxis, and pathophysiology of CMV pneumonitis are discussed.
Insights
Cytomegalovirus (CMV) pneumonitis remains a lethal risk post-transplant. Early diagnosis via pp65 antigenemia assay aids in managing CMV viremia and preventing severe lung complications in immunocompromised patients.
Area of Science:
- Immunology
- Pulmonology
- Transplantation Medicine
Background:
- Cytomegalovirus (CMV) infection poses a significant risk for severe complications, including pneumonitis, in solid organ transplant recipients.
- While less frequent due to advancements, CMV pneumonitis can be lethal.
- Subclinical pulmonary involvement in CMV viremia is detectable even before symptoms manifest.
Purpose of the Study:
- To review the clinical and subclinical pulmonary manifestations of CMV infection in immunocompromised individuals, particularly transplant recipients.
- To provide a comprehensive overview of CMV pneumonitis, covering its clinical course, diagnosis, treatment, and prevention.
Main Methods:
- Literature review focusing on clinical studies, diagnostic advancements, and therapeutic strategies for CMV pulmonary involvement.
- Discussion of pathophysiology and clinical presentation of CMV pneumonitis in the context of immunosuppression.
Main Results:
- The pp65 antigenemia assay allows for early and rapid detection of CMV viremia in transplant patients.
- Decreased pulmonary diffusion capacity can be observed in asymptomatic patients with CMV viremia.
- CMV pneumonitis, though infrequent, remains a critical concern with potentially fatal outcomes.
Conclusions:
- Early diagnosis and management of CMV viremia are crucial for preventing severe pulmonary complications in transplant recipients.
- Understanding the pathophysiology and clinical spectrum of CMV pneumonitis is essential for effective patient care.
- Prophylaxis and timely therapeutic interventions are key to mitigating the risks associated with CMV pulmonary disease.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
