ABSTRACT
Chagas' disease was present in 17.22% of persons undergoing kidney transplantation in an Argentine Hospital. The criterion for attributing reactivation of chronic Chagas' disease and transmission of Trypanosoma cruzi to grafts was detection of parasites in blood (patent parasitemia) or tissues. Reactivation was diagnosed in 5 (21.7%) of 23 recipients. Ten (43.4%) of 23 chagasic recipients without reactivation of chronic Chagas' disease had abrogation of serological reactivity. T. cruzi infection was transmitted to 3 (18.7%) of 16 non-chagasic recipients. Reactivation and infection were diagnosed by patent parasitemia or cutaneous panniculitis. For diagnosis, detection of parasites in blood and tissues had more relevance than serology. Sequential monitoring detected early reactivation and infection, permitting application of preemptive or therapeutic therapy with benznidazole, thus inhibiting, in all patients, severe clinical disease produced by a progressive and systemic replication of the parasite.

The risk of HBV and HCV liver infection in kidney graft recipients was evaluated in 35 patients. All were tested for anti-HBc, HBsAg, HBeAg, anti-HBs, Anti-HBe, anti-HCV (c-100-3 and c-100-3, c-22, 33-c), anti-HDV and anti-HIV by ELISA, and for HBV-DNA by hybridization. Liver biopsy, immunostaining for HBcAg and Knodell's hepatic inflammatory index were performed in 18. Mean time elapsing form transplant to inclusion was 20.7 months (range 1-108). HBsAg was the only marker searched for prior to transplant. Twenty six (74.2%) patients presented HBV and/or HCV markers, while 9 (25.8%) had none; 16 (45%) proved anti-HBc+, 6(17.1%) HBsAg+, (3 HBeAg+ and 3 anti-HBe+), 7 (20%) anti-HBs+ and 3 (8.5%) isolated anti-HBc. Anti-HCV (C-100-3) was positive in 9/32 (28.1%), while 2nd. generation anti-HCV was positive in 20/35 (57.1%) cases. No false positives for 1st. generation test were found. Both anti-HDV and anti-HIV were negative in all the sample. Raised aminotransferases were present in 13/30 (43.3%), 7 in anti-HCV+, one in HBsAg+ and 3 in HBsAg+/HCV+ cases, but normal in 17/30 (56.6%). History of Transfusion and Hemodialysis time showed no significant differences between anti-HCV+ and anti-HCV negative cases. Biopsy disclosed 10 chronic persistent hepatitis (CPH), one chronic active hepatitis (CAH) with cirrhosis, one inactive cirrhosis (Ci) 4 minimal lesions (MHL) and 2 normal. Seven CPH, 3 MHL. one normal and both cirrhosis cases proved anti-HCV+. HBsAg was positive in the single CAH, in 2 CPH and in one MHL.(ABSTRACT TRUNCATED AT 250 WORDS)
