Long-term outcomes of pre-emptive valganciclovir compared with valacyclovir prophylaxis for prevention of cytomegalovirus in renal transplantation.
Prevention of cytomegalovirus (CMV) is essential in organ transplantation. The two main strategies are pre-emptive therapy, in which one screens for and treats asymptomatic CMV viremia, and universal antiviral prophylaxis. We compared these strategies and examined long-term outcomes in a randomized, open-label, single-center trial. We randomly assigned 70 renal transplant recipients (CMV-seropositive recipient or donor) to 3-month prophylaxis with valacyclovir (n=34) or pre-emptive valganciclovir for significant CMV viremia detected at predefined assessments through month 12 (n=36). Among the 55 patients who had a protocol biopsy specimen available at 3 years to allow assessment of the primary outcome, 9 (38%) of 24 patients in the prophylaxis group and 6 (19%) of 31 patients in the pre-emptive therapy group had moderate to severe interstitial fibrosis and tubular atrophy (odds ratio, 2.50; 95% confidence interval, 0.74-8.43; P=0.22). The prophylaxis group had significantly higher intrarenal mRNA expression of genes involved in fibrogenesis. The occurrence of CMV disease was similar in both groups, but pre-emptive therapy improved 4-year graft survival (92% versus 74%; P=0.049) as a result of worse outcomes in patients with late-onset CMV viremia. In conclusion, compared with valacyclovir prophylaxis, pre-emptive valganciclovir therapy may lead to less severe interstitial fibrosis and tubular atrophy and to significantly better graft survival.

[Scleromalacia associated with varicella-zoster virus].
Scleromalacia usually appears following vasculitis in systemic rheumatoid diseases, especially as a late symptom of rheumatoid arthritis.. A 67-year-old woman was referred to our hospital for further evaluation with the diagnosis of a "fast-growing tumor" of the left eye. Sixteen months ago she had suffered from herpes zoster ophthalmicus-associated keratouveitis and trabeculitis in the same eye. Scleromalacia associated with varicella-zoster virus (VZV) was diagnosed after the biomicroscopic and gonioscopic examination of the eye was completed and a systemic disease had been ruled out. One week after beginning systemic application of acyclovir (5 x 800 mg daily) and prednisolone (30 mg daily), the anterior chamber inflammation regressed and a fibrosis seemed to appear in the atrophic scleral area.. Although scleral atrophy mostly appears as a late sign of systemic rheumatoid diseases, it might also develop secondary to infectious diseases. Scleromalacia associated with varicella-zoster virus has been previously described only in a few cases. Scleromalacia is a vision-threatening complication of zoster ophthalmicus which responds well to combination therapy with systemic antiviral and anti-inflammatory agents.
