- This report described an interim analysis of a investigator-driven multicenter trial in renal transplant recipients: the Prospective Quality of life Renal Transplantation Switch Study; Tacrolimus-based immunosuppression ("PQRST study"). Patients included in the trial initially treated with cyclosporine-based immunosuppression after renal transplantation who experienced side effects, such as hypertension, hyperlipidemia, hypertrichosis, or other adverse reactions, were converted to a tacrolimus-based immunosuppressive regimen (n = 31). Steroids were subsequently discontinued between 3 and 6 months after the conversion. As of today 19/31 (50%) patients have been successfully weaned off steroids with the remaining patients in this process. In this interim analysis, with a follow-up ranging from 1 to 18 months both patient and graft survivals were 100%. No patient experienced an acute rejection episode; none of the grafts were lost. Blood pressure decreased in 22/31 (71%) of the patients. No patient developed de novo diabetes or other serious side effect related to the conversion. Three patients were withdrawn from the trial because of side effects: bleeding, depression, and proteinuria. However, none of these adverse events were felt to be directly related to the change of the immunosuppressive regimen to tacrolimus monotherapy. In conclusion, conversion from cyclosporine to tacrolimus-based therapy was safe and well tolerated; it may improve the cardiovascular risk profile after kidney transplantation.

- Our objective was to compare the efficacy and safety of gabapentin and vigabatrin as first-line add-on treatment in patients with partial epilepsy.This was a multicenter, double-blind, randomized dose titration study. After baseline assessment and randomization, the dose could be increased if seizures persisted and reduced if side effects occurred. Health-related quality of life was assessed at baseline and at the end of the study. By a protocol amendment post hoc, all randomized patients were offered a standardized perimetry examination at the end of the study. Improvement rate was the proportion of patients with a reduction of seizure frequency of at least 50% during an 8-week period without any adverse events causing withdrawal.One hundred two patients were randomized and analyzed on an intent-to-treat basis. The improvement rate was 48% in the gabapentin group and 56% in the vigabatrin group. The improvement rate, when per protocol criteria were fulfilled, was 57% in the gabapentin group and 59% in the vigabatrin group. The proportion of seizure-free patients was 31% in the gabapentin group and 39% in the vigabatrin group. There was no difference in quality-of-life scores between the groups. Perimetry after termination of the study on 64 patients showed abnormal results in 3 of 32 patients in the vigabatrin group.Approximately one third of the patients in both groups became seizure-free. Although no major differences were seen in terms of the improvement rate between the groups, equivalence between the two drugs was not found.

- Objective. There have been no endpoint studies with statins for patients with severe renal failure. The purpose of this prospective, open, randomized, controlled study was to investigate whether atorvastatin (10 mg/day) would alter cardiovascular endpoints and the overall mortality rate of patients with chronic kidney disease stage 4 or 5 (creatinine clearance < 30 ml/min).Material and methods. The study subjects comprised 143 patients who were randomized either to placebo (controls; n=73; mean age 69.5 years) or to treatment with atorvastatin (n=70; mean age 67.9 years). The patients included were either non-dialysis (n=33), haemodialysis (n=97) or peritoneal dialysis (n=13) patients. Analysis focused on the primary endpoints of all-cause mortality, non-lethal acute myocardial infarction, coronary artery bypass graft surgery and percutaneous transluminal coronary angioplasty. Statistical analysis for endpoint data was mainly by intention-to-treat.Results. Primary endpoints occurred in 74% of the subjects. There was no difference in outcome between the control and atorvastatin groups. The 5-year endpoint-free survival rate from study entry was 20%. Atorvastatin was withdrawn in 20% of patients due to unacceptable side-effects. In the atorvastatin group, low-density lipoprotein (LDL) cholesterol was reduced by 35% at 1 month and then sustained. The controls showed a progressive reduction in LDL cholesterol until 36 months.Conclusions. Although atorvastatin reduced total and LDL cholesterol effectively it was not beneficial regarding the long-term outcomes of cardiovascular endpoints or survival. In contrast to other patient groups, patients with severe chronic kidney disease, especially those on dialysis, seem to derive limited benefit from this lower dose of atorvastatin.
