    ABSTRACT: Rapid bone loss and fractures occur early after solid organ transplantation. We examined the preliminary results of a prospective study evaluating the efficacy of prophylactic use of bisphosphonates in renal allograft recipients. Bone mineral density (BMD) was measured at the lumbar spine and the hip by dual energy X-ray absorptiometry at 1, 6, 12 months. Alendronian or risedronian were initiated for patients with osteopenia or osteoporosis at 1 month who had no contraindications to bisphosphonates. The treatment lasted at least 6 months. Sixty-six patients were included in the study; 39 were treated with bisphosphonates (A), and 27 were drug-free (B). Presently, 24 group A and 13 group B patients have completed the 12-month observation period. In group A 53.8% (21) subjects had osteoporosis and 46.2% (18), osteopenia. Mean T-score L(2)-L(4) in group A at 1, 6, and 12 months were: (-)2.22 +/- 1.06; (-)2.07 +/- 1.25; (-)1.89 +/- 1.07, respectively. The T-score increase between 6 and 12 months was significant (P = 0.0014). The relative rise in BMD L(2)-L(4) between 1 and 12 months was 2.26%. In group B mean T-score L(2)-L(4) at 1, 6, and 12 months were: (-)0.26 +/- 1.34; (-)0.80 +/- 1.19; (-)1.2 +/- 1.59, respectively. The T-score decrease between 1 and 12 months in group B was significant (P = .0082). The 12-month relative decrease in femoral neck and trochanter BMD in group B was (-)2.1% and (-)2.75%, respectively. Bisphosphonates are effective for prophylaxis of rapid bone loss early after renal transplantation.

    ABSTRACT: Chronic allograft nephropathy (CAN) is the most important cause of late renal allograft loss. The standard diagnosis of CAN is based on pathological examinations according to Banff'97 scheme. The aim of the study was to evaluate the usefulness of tubular and glomerular proteinuria in non-invasive recognition of vascular changes accompanying CAN (AH--arteriolar hyaline thickening, CV--vascular fibrous intimal thickening). beta 2- and alpha 2-microglobulin (beta 2-m and alpha 2-m), albumin (alb), immunoglobulin G (IgG), total protein (tp) and creatinine (cr) concentration were measured in the second time urine specimen in 66 renal allograft recipients. Then the subsequent renal biopsies were done. The aim of statistical analysis (MANOVA, Stepwise Discriminant Analysis, SDA) was to diagnose CV and AH changes based on results of urine analysis listed above and the patient's age, time after transplantation and serum creatinine level (scr). Results obtained with statistical analysis were in 90.91% and 87.69% identical with CV and AH pathological diagnoses, respectively.
