“…It has been widely reported that patients with inflammatory bowel disease who are receiving azathioprine treatment are susceptible to CMV infection [ 8 – 11 ]. A systemic review of CMV pneumonia in patients with inflammatory bowel disease found that thiopurines carry a disproportionately higher risk of viral infection reactivation, particularly CMV [ 12 ].…”

“…Furthermore, CMV infection can present in various ways. Besides CMV pneumonitis, several case reports showed that immunosuppressive therapy might have a role in development of CMV retinitis [ 13 , 14 ], as well as thrombocytopenia [ 15 ], myalgia [ 16 ], arthralgia [ 17 , 18 ], hepatitis [ 19 ], pericarditis [ 20 ], or gastrointestinal [ 8 , 10 ] and neurological disorders [ 19 , 21 ], and even oral ulcers [ 22 , 23 ]. In some rare cases, CMV infection also presents as nephrotic syndrome.…”

Patient: Female, 68-year-old Final Diagnosis: Nephrotic syndrome Symptoms: Edema • fever • oliguria • proteinuria Medication: — Clinical Procedure: — Specialty: Nephrology Objective: Rare coexistence of disease or pathology Background: Patients taking azathioprine (AZA) are very susceptible to development of cytomegalovirus (CMV) infection. The symptoms of CMV infection are varied. In some rare cases, CMV infection can even result in nephrotic syndrome. Case Report: Here, we present a rare case of nephrotic syndrome associated with CMV infection, induced by azathioprine in-take. The patient, diagnosed with myasthenia gravis, was initially treated with azathioprine for 2 years. Then, the patient was admitted to the hospital due to nephrotic syndrome and acute kidney injury. Minimal change disease with acute tubular necrosis were diagnosed through biopsy. After an initial good response to hemodialysis and steroids, the patient developed severe pneumonia and oral ulcers. Further anti-CMV IHC staining of kidney tissues showed positive cells in tubules, indicating nephrotic syndrome secondary to CMV infection. Conclusions: This case reminded us that CMV may be an under-recognized cause of nephrotic syndrome. Patients treated with azathioprine are very susceptible to developing CMV infection. During the diagnosis of nephrotic syndrome, we should always take CMV infection into consideration, especially in patients with on azathioprine.
