ABSTRACT
Objective To improve the awareness,diagnosis and treatment of pneumocystis carinii pneumonia (PCP) after renal transplantation.Methods A retrospective review was performed in 28 patients who underwent renal transplantation and developed PCP afterwards.The main clinical manifestations were fever(28 cases),nonproductive cough(28 cases),chest distress (12 cases).Occurrences of PCP were described 1.5 to 7 months after the renal transplantation.There were 10 patients treated with tacrolimus (FK506 2-6 rag/d,FK506 concentration 4-10 ng/ml) and 18 patients treated with cyclosporine (CsA 200-500 mg/d,CsA trough level150-250 ng/ml) based immunosuppressive regimen.Anti-CD_(25)~+ monoclonal antibody (anti-CDCD_(25)~+mAb) was used in 10 cases for immune induction before operation while single steroid in 18 cases.Creatinine of patients with PCP was 70 to 106 μmol/L.CD_4~+ lymphocyte counts of the peripheral blood were 245±32/μl before PCP treatment and 536±25/μl after recovery.The most abnormal chest radiological findings were bilateral patchy ground-glass opacity.All the patients were diagnosed with PCP by bronchoalveolar lavage.Treatment was performed by reducing immunosuppressive agents and giving SMZco.Nineteen patients who had a PaP2 less than 70 mm Hg were given intravenous small-dose steroid.Results All the patients recovered from PCP 2 to 3 weeks after treatment.One patient experienced recurrence half year later.Five patients with higher creatinine after treatment recovered to normal levels after stopping the treatment of SMZco.No significant differences were seen in PCP patients treated with CsA and FK506,P>0.05.The similar results were observed in use of anti-CDCD_(25)~+ mAb and single steroid,P>0.05.Significant differences were observed in PCP patient peripheral blood CD_4~+ lymphocyte counts before and after treatment (P=0.001).Conclusions Patients who have fever,cough and hypoxia,chest imaging showing bilateral lung interstitial inflammation,might be PCP patients in the early post-renal transplantation period.Effective treatment should be performed by reducing immunosuppressive agents and giving SMZco.
