The purpose of this work was to compare hybridization and PCR methods as diagnostic tests in diagnosing and monitoring CMV infection. The investigation was performed in a group of 24 renal transplant recipients treated with ATG. The results we obtained suggest that quantitative variant of hybridization is more useful in diagnosing the infection than PCR, because it enables to monitor the infection. DNA CMV level of about 60 pg/ml or the increasing level in the subsequent samples should be a sign to start antiviral therapy.

Perioperative single high dose ATG-Fresenius S administration as induction immunosuppressive therapy in cadaveric renal transplantation--preliminary results.

Monoclonal and polyclonal antilymphocyte antibodies have been used successfully in organ transplantation as induction therapy and in the treatment of acute graft rejection. Used for induction the medication is generally given for the first 7-10 days. The aim of this study was to assess the safety and efficacy of single high dose (9 mg/kg) ATG Fresenius S given perioperatively, before revascularization, to kidney allograft recipients. During last twelve months seventy six, first cadaveric kidney adult recipients were included into the study in two centers (center A-64, center B-12). All patients received triple drug immunosuppression (Neoral, steroids and Cellcept which was replaced by azathioprine after 4 months), and were randomized to receive ATG or not. The follow-up period ranged from 1 month up to 1 year. The preliminary results are very promising, the rejection rate in bolus group was significantly lower than in control. No significant side effects or serious adverse events in both groups were observed.

Cyclosporine A blood concentration during pregnancy in renal allograft recipients.

Pregnancy-induced changes increase hazards associated with cyclosporine (CsA) treatment. Blood CsA trough levels (C0) were estimated in 15 pregnant renal allograft recipients treated with prednisolone + CsA + azathioprine using the TDx Abbott fluorescent polarization immunoassay. Despite therapeutical dose levels of CsA administered during pregnancy (3.52-3.67 and 3.59 mg/kg body weight in the first, second, and third trimesters, respectively), C0 significantly decreased (first trimester 130.8 +/- 36.9, second 92.0 +/- 32.7, and third 99.0 +/- 36.9 ng/ml). The mean increase of patient's body weight in mid-pregnancy was 3.0 +/- 2.19 kg and was associated with a significant (P < 0.05) fall in a hematocrit value (from 42 +/- 4.9% prior to pregnancy to 34 +/- 6% at the 20th week). We postulate that C0 concentration does not reflect the true exposure to CsA as no episodes of acute graft rejection were observed during pregnancy.

Long-term results of treatment of chronic hepatitis B, C and D with interferon-alpha in renal allograft recipients.

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.
