Severe gastrointestinal cytomegalovirus disease in two patients with renal vasculitis after immunosuppression
Abstract:
Although the use of current immunosuppressive regimens has significantly improved the outcomes of autoimmune renal diseases, infectious complications remain an important clinical concern. Cytomegalovirus (CMV) infection has been shown to be one of the major causes of mortality in this group of patients. We report two cases of renal vasculitis (Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA)) that developed into severe gastrointestinal CMV disease and manifested with massive small bowel bleeding, resulting in an eventual fatal outcome for one of the patients. Risk factors, pathogenesis, role of immunosuppression in the development of CMV infection, and antiviral treatment are discussed in this review. These cases highlight the need for further research to evaluate the complex mechanisms between immunosuppression and CMV occurrence as well as the role of antiviral prophylaxis in high-risk patients undergoing immunosuppressive therapies. .
Insights
Cytomegalovirus (CMV) infection is a serious risk for patients with autoimmune kidney diseases on immunosuppressants. This review highlights severe gastrointestinal CMV disease in two renal vasculitis cases, emphasizing the need for further research.
Area of Science:
- Nephrology
- Infectious Diseases
- Immunology
Background:
- Immunosuppressive therapy improves outcomes for autoimmune renal diseases but increases infectious risks.
- Cytomegalovirus (CMV) infection is a significant cause of mortality in these patients.
- Autoimmune renal diseases include conditions like Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA).
Observation:
- Two cases of renal vasculitis (GPA and MPA) developed severe gastrointestinal CMV disease.
- The patients presented with massive small bowel bleeding.
- One patient experienced a fatal outcome due to the complications.
Findings:
- Severe gastrointestinal CMV disease can manifest in patients with autoimmune renal vasculitis.
- Immunosuppression plays a critical role in the development and severity of CMV infections.
- Massive gastrointestinal bleeding is a potential complication of severe CMV disease in this context.
Implications:
- Highlights the critical need for understanding the interplay between immunosuppression and CMV.
- Suggests exploring the role of antiviral prophylaxis in high-risk patients undergoing immunosuppressive therapy.
- Underscores the importance of vigilance for infectious complications in patients with autoimmune renal diseases.
