Abstract
We evaluated the effects of treatment with interferon (IFN) on liver disease and renal allograft function in ten immunosuppressed cadaver kidney recipients. Two females and eight males (mean age 39 years) with biopsy-proven chronic active hepatitis (n = 8) or persistent hepatitis (n = 2) and serum positive for hepatitis B surface antigen (HBsAg) and HBe antigen (n = 5) or serum positive for anti-HCV antibodies (n = 3) or serum positive for HBsAg, anti-HCV and anti-HDV antibodies (n = 2) received 3 million units IFN thrice weekly of 6 months. All patients responded with a reduction in serum aminotransferase activity and in five of them liver function completely normalized. Three patients among five infected with HBV cleared HBeAg. During the follow-up period liver function remained stable in 9 patients after discontinuation of IFN therapy. Three patients lost their grafts due to rejection 1, 2, and 4 months after IFN therapy, respectively. In six patients renal function remained stable during and after IFN therapy. We conclude that in selected groups of renal allograft recipients IFN can be used safely and effectively for the treatment of chronic viral hepatitis.

Abstract
UNLABELLED Various oxidant species, oxygen free radicals (OFR) implicated in patients with chronic renal diseases treated with dialysis and after cadaveric renal transplantation. Oxidative stress occurs when free radical generation exceeds antioxidant defence. We therefore examined markers of lipid peroxidation and antioxidant potential in blood (serum, plasma, RBC) of very carefully (clinically and biochemically) selected 102 subjects (56 female and 46 male, mean age 37.5 +/- 7 years). Included were 51 renal allograft recipients (RARs); 15 patients with glomerulopathies (GL); 36 healthy age- and sex-matched volunteers as a control group (C). All RARs were divided into two subgroups: RARs-A (n = 28) were treated with triple drug therapy including cyclosporin A (CsA) and RARs-Z (n = 23) were on double drug regimen: prednisone, azathioprine. Patients with coronary artery disease (CAD), diabetes, serum creatinine concentration > 2.0 mg/dl, acute rejection and infections were excluded. We used several automated assays to estimate: malondialdehyde (MDA); total radical-trapping antioxidant potential (TRAP), glutathione peroxidase (GPx), glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), vit. E and lipid profiles. Patients of RARs-A were found to have significantly elevated triglycerides; cholesterol-LDL; MDA; TRAP and decreased activity of RBC glutathione peroxidase as compared with those of RARs-Z and group C. IN CONCLUSION our data show that oxidative stress (with prooxidant effect of CsA partly at least), with reduced in antioxidant potential of defences system is associated with kidney transplantation.

Abstract
We evaluated the impact of concomitant infection with Hepatitis B virus (HBV) and Hepatitis C virus (HCV) on the clinical course after renal transplantation (Tx). In 335 patients (pts) transplanted between 1991 and 1993 we found 30 (9%) recipients who were positive for Hepatitis B surface antigen (HBsAg) (ELISA, Organon) and anti-HCV antibodies (immunoblot assay Lia Tek) preTx. Chronic liver disease (CLD) (two-fold or greater increase in serum ALT and AST levels for at least six months) developed in 40.7% coinfected pts as compared to 24.4% and 25.7% pts infected only with HCV or HBV, respectively. Maintenance immunosuppression consisted of P + Aza + CsA, mean follow-up time was 28 +/- 15 months. The mean time of the onset of CLD was 3.0 months (range: 1-18 months) after Tx. Percutaneous liver biopsy performed in 5 CLD pts revealed chronic active hepatitis (CAH) in 4 and chronic persistent hepatitis (CPH) in 1 pt. Four pts who had CAH and were positive for HCV RNA (RT PCR) in serum and for HBcAg in liver tissue, received interferon-alpha therapy for 6 months. Clinical improvement of liver function was observed in all of them, but none cleared HBsAg or HCV RNA. One pt lost his graft due to acute rejection. Concomitant infection with HBV and HCV is associated with the high risk of development of CLD early after Tx. We recommend that pretransplant evaluation of both anti-HCV and HBsAg positive pts should include liver biopsy to exclude potential recipients with CAH.

Abstract
The aim of this study was to evaluate the efficacy and safety of interferon-alpha (IFN-alpha) therapy of chronic hepatitis B, C and D (HBV, HCV and HDV, respectively) in renal transplant recipients. A group of 42 patients (30 males, 12 females, mean age 38 years) with documented viraemia and chronic active hepatitis (CAH) were studied, of whom 1 had HBV infection alone, 11 had HCV infection alone, 3 had HBV and HDV infection concomitantly, 12 had HBV and HCV infection concomitantly, and 2 had HBV, HCV and HDV infection concomitantly. Patients received 3 MU IFN-alpha three times weekly for 6 months. After IFN-alpha therapy, 18 patients (43%) achieved normal alanine aminotransferase (ALT) activity and a partial response was observed in 12 (29%) patients. Two patients relapsed (one with HCV and one with HBV + HCV infection) immediately after the cessation of IFN-alpha therapy. Repeated liver biopsy was performed in 16 patients after 6-24 months of therapy and revealed progression to cirrhosis in five patients, remission in two and stable disease in nine. None of the patients cleared HCV RNA, four patients cleared HBeAg (two also HDV), and one both HBV and HCV. Five patients died during IFN-alpha therapy (one as a consequence of liver failure), and four died during the 6 months after therapy (two as a consequence of liver failure). During IFN-alpha therapy renal allograft function remained stable in 31 patients and acute rejection episodes occurred in 7, of whom 5 lost their graft and all had experienced rejection episodes before. In 16 patients normalization of ALT continued during long-term follow-up (median 22 months, range 0-84 months). IFN-alpha seemed to be moderately effective in the treatment of chronic HBV or HCV infections, but cannot be recommended for recipients infected with both HBV and HCV.

Abstract
AIM Comparison of eye fundus changes in patients in whom malignant hypertension was diagnosed. MATERIAL AND METHODS 14 patients (6 F, 8 M) aged 24-54 years were examined. In all cases kidney disease was the cause of arterial hypertension. 11 patients underwent kidney transplantation (0.5-20 years before the study), 2 patients was hemodialysed, 1 received only pharmacological treatment. RESULTS During the first examination in two patients IV grade of hypertensive retinopathy (K-W classification) was found, in the rest of the patients I/II or II grade with typical changes for malignant hypertension in the past (Elschnig's spots) was found. In control examinations (6 months-21 years) the persistence of the previously noticed changes was observed.

Abstract
The administration of nitrogranulogen in a dose of 0.01 mg/kg in patients with primary glomerulopathies caused a significant reduction in proteinuria in 10 out of 12 cases. In one patient the effects was striking (fall of proteinuria from 10 g/24 hrs to trace amounts). A trend towards the normalization of helper T lymphocytes (CD4+) was noted as well as a significant drop in NK lymphocytes. No side effects or drug-related complications were observed.

Abstract
The number of interleukin 2 receptor positive T cells freshly isolated from peripheral blood as well as stimulated in culture with PHA was determined in renal allograft recipients with stable graft function, rejection and CMV infection. The most typical phenotype was observed during CMV infection. Patients with CMV had very low levels of circulating positive cells which responded normally to mitogen stimulation in vitro.

Abstract
Ophthalmological examinations were carried out in 42 patients (aged 16-45 years) after kidney transplantation in whom malignant hypertension was discovered before transplantation. The first funduscopy revealed pathological changes of various type and grade (I-IV), in 17 patients the visual acuity was lowered and in 18 the ERG record was pathological (residual or extinguished). The control examinations performed in 19 patients after 1-5 years showed that the changes typical for malignant hypertension receded in 7; the fundus of the rest of the patients was the same as before. The lack of improvement in the ERG record points to a permanent lesion of the retinal activity after passed malignant hypertension in spite of normalization of the arterial pressure.

Abstract
Fifty cases of idiopathic membranoproliferative glomerulonephritis were followed up for an average of 10 +/- 0.9 (SE) years. Forty of them, who presented a nephrotic syndrome, were treated by immunosuppressive drugs (prednisone, azathioprine, chlorambucil, cyclophosphamide) for 79 +/- 9.7 (SE) months. Cumulative survival ratio for 5, 10 and 15 years after enrollment was 0.90, 0.82 and 0.77 and after appearance of first symptoms or signs of kidney disease as determined by anamnestic data 0.97, 0.91 and 0.90 accordingly. Triple-drug therapy (prednisone and azathioprine combined with chlorambucil or cyclophosphamide) was more effective in improving proteinuria than other immunosuppressive regimens. No serious side effects were encountered.

Abstract
Prolonged combined treatment with prednisone and immunosuppressive drugs can, if started early enough, significantly reduce the degree of proteinuria and preserve renal function. This is not necessarly associted with simultaneous histological improvement confirmed by renal biopsy. The proposed method of treatment deserve further evaluation.
