Abstract:
Objective: To analyze the clinical]features of the patient with nephrotic syndrome who developed Pneumocystis carinii pneumonia (PCP) and cytomegalovirus pneumonia (CMP) after oral administration of tacrolimus caspsules, and to discuss the correlations between immunosuppressive patient and Pneumocystis carinii (Pc) and cytomegalovirus (CMV) infection, and to provide the basis for the reasonable treatment plan in the early stage. Methods: The clinical materials of one patient with nephrotic syndrome who developed PCP and CMP after oral administration of tacrolimus capsules were collected and the clinical symptoms, past medical history and outcomes, auxiliary examination, treatment plan and prognosis were analyzed; the relevant literatures were reviewed. Results: The male 47-year-old patient was admitted to hospital because of cough for 1 month, shortness of breath for 1 week and fever for 3 d. The patient had the history of diabetes mellitus and took the medication regularly , and the level of blood sugar was well controlled. At the beginning of 2018, the patient received renal biopsy due to edema of the lower extremities and was diagnosed as stage II membranous nephropathy accompanying with mild mesangial proliferative diabetic nephropathy; the patient was orally administrated with glucocorticoid. In July 2018, the patient was diagnosed as nephrotic syndrome and stage II membranous nephropathy, and had been orally administrated with tacrolimus capsules after discharge. After admission, the patient developed acute respiratory distress syndrome rapidly; the multiple exudation and nodular foci of both lungs were found on the chest imaging, and the infectious lesions were considered. The IgM antibody and IgG antibody of CMV of the patient were both positive. The high throughput gene detection results of the infection pathogens in blood showed Pneumocystis jiroveci of Pneumocystis and human herpesvirus 5 (HHV-5). PCP complicated with CMP was diagnosed definitively. The patient was treated with sulfamethoxazole combined with ganciclovir and noninvasive ventilation. The patient was discharged after the condition was improved. Conclusion: The patient with low immunity should be alert to the mixed infection of PCP and CMP if he develops rapidly progressive hypoxemia.
