Results of renal transplantation on conventional immunosuppression in second decade in India: a single centre experience.
BACKGROUND
In-spite of many renal transplant (RT) centres in the country, there is paucity of data on the survival results in India. Furthermore, there is hardly any data of results in second decade. In this study we present the results of RT in second decade at our centre.


METHODS
RT at our hospital is being done since 1972. First eight years saw occasional RT and complete data is not available in these patients. So, we have excluded these patients from the study. We have included rest all 144 patients who had RT between Jan. 1981 to Dec. 1989, so as to have at least 10 years of follow-up or more. All these patients were on conventional immunosuppression.


RESULTS
Of the 144 patients, 126 (87.5%) were males and the mean age was 29.5 +/- 8.5 years (range 14-54). Basic disease was presumed chronic glomenulonephritis (CGN) in 79.9%, vesicouretenic reflux (VUR) in 8% and diabetic nephropathy in 1.4% patients. Mean number of haemodialysis (HD) and blood transfusion before RT were 44 +/- 24.7 and 8.9 +/- 4.7 (range 0-25), respectively. Mean donor age was 40.9 +/- 10.1 year (range 18-62). HLA matching was haploidentical in 74.5% cases, HLA identical in 3% cases and 11.5% were less than two-antigen match. Of the 63% patients, who had at least one acute rejection (AR) during their follow-up, 78.8% cases had this AR within first three months after the renal transplant. During 10 years of follow up, 65 patients died (23 with normal graft function and 42 with chronic rejection) and 17 lost to follow-up. Eight patients lost their graft but were surviving at 10 years and 54 had functioning graft till the time of analysis. With mean follow-up of 83.9 +/- 61.2 (range 1-216) months, 10-year actuarial patients and graft survival was 53% and 47%, respectively. Graft half-life in these patients is 92 months. In multivariate analysis of the donor age, number of blood transfusion (BT), degree of HLA matching and AR, only AR was found to be statistically correlated with the graft outcome (p=0.004).


CONCLUSIONS
Our study concludes that in our set-up during eighties, on conventional immunosuppression, actuarial patient and graft survival at 10 year is 53% and 47%, respectively with graft half-life being 92 months. Only acute rejection has been found to affect the graft outcome in these patients.
