Pneumonia occurred in 8 cases of 70 renal transplant recipients. Infections appeared from 40 days to 30 months after renal transplantation, predominintly after 6 months (75 %).
Three cases were caused by fungi (2 by Aspergillus, 1 by Cryptococcus). Another 6 cases had several episodes of rejections, but two cases had no episode. Severe interstitisl pneumonia occurred in 3 patients after the Pulse therapy to rejections and all of them died.
With regard to complications, liver dysfunction was presented in 2 cases, G-I troubles in 2 cases, and Cryptococcal menigitis in one case.
Therefore, critical care must be performed during Pulse therapy to prevent pulmonary infections and its complications.
