ReviewCost-effectiveness of TNF-alpha-blocking agents in the treatment of rheumatoid arthritis.
The current literature covering cost-effectiveness and cost-utility analyses of biological treatments in patients with rheumatoid arthritis (RA) are reviewed in order to discuss options and limitations for future application of these highly priced drugs in routine clinical practice. The cost-effectiveness and cost-utility ratios of the studies analysed are converted into the corresponding Euros of the publication year. Etanercept treatment achieved a cost-effectiveness ratio of 44,300 Euros (2002)/ACR 20 (20% response according to American College of Rheumatology criteria) and 43,100 Euros (2002)/ACR 70WR (ACR 70 weighted response) compared with sulfasalazine and methotrexate, respectively, in methotrexate-naive RA. ⋯ No substantial differences of cost-utilities of infliximab and etanercept were found. The administration of these drugs as third-line therapy is regarded cost-effective compared to other well-accepted therapies with comparable cost-utility ratios of < 50,000 Euros/QALY gained. Still, data on economic outcomes of RA trials are sparse and further cost-effectiveness and cost-utility evaluations are needed.

ReviewValganciclovir: oral prevention and treatment of cytomegalovirus in the immunocompromised host.
Herpes virus infections, particularly those caused by cytomegalovirus (CMV), lead to significant and, sometimes severe, clinical problems for the immunocompromised host. As effective agents have become available, several treatment and prevention strategies have evolved over the past decade, first in intra-venous form and more recently, as oral preparations. Valganciclovir, the valine ester of ganciclovir, is an orally administered, potent, antiviral agent active against all herpes viruses. ⋯ Clinical trials evaluating the safety and efficacy of valganciclovir for the treatment of new AIDS-associated CMV retinitis showed equivalency to intravenous ganciclovir and prevented progression of quiescent disease. In solid organ recipients, once-daily valganciclovir has been proven equivalent to oral ganciclovir for the prevention of CMV infection. The high bioavailability and convenient dosing formulation make valganciclovir an attractive option for these indications.
