pylori infection, serological analysis of the antibody titers was done. Immunohistochemical analyses were applied to the tissue samples. Results. Serology was found positive at the 90.3% of the laryngeal

cancer patients and 96.4% of the benign group. There were no statistically significant differences between the two groups (P > 0.05). Immunohistochemical analysis results were determined as negative at all of the specimens of laryngeal cancer patients and patients with benign lesions. Conclusion. There were no signs of colonization of H. pylori in laryngeal tissues of both groups’ patients. It is thought that no relationship exists between the H. pylori infection and laryngeal squamous cell carcinoma.”
“Background: Abacavir sulfate (abacavir) is associated with a hypersensitivity reaction (HSR) that this website affects 5-8% of patients. While serious complications are rare, failure to identify it, or abacavir re-challenge following

HSR, can be fatal. Genetic screening for HLA-B*5701 can identify patients who are likely to experience an HSR and reduces the incidence MCC950 in vitro of the reaction.

Objective: We assessed the intrinsic and practical value, from the US healthcare system perspective, of prospective HLA-B*5701 screening among a population of antiretroviral-naive patients without elevated risk factors for cardiovascular disease, plasma HIV RNA >100 000 copies/mL, or preexisting renal insufficiency.

Methods: Two approaches were used to evaluate the costs and benefits of prospective screening. First, the efficiency of HLA-B*5701 screening compared with no screening prior to abacavir initiation (intrinsic value of screening) was evaluated using a 60-day decision-tree model. Next, the practical value of screening was assessed using a lifetime discrete-event simulation model that compared HLA-B*5701 screening prior

to abacavir use versus BYL719 initiation with a tenofovir-containing regimen. Screening-effectiveness parameters were taken from an open-label trial that incorporated screening prior to abacavir initiation and other published studies. Treatment efficacy was derived from clinical trials. Modelling assumptions, costs ($US, year 2007 values) and other parameters were derived from published sources, primary data analysis and expert opinion. Multiple one-way sensitivity and scenario analyses were performed to assess parameter uncertainty.

The primary outcome measure for the short-term screening versus no screening analysis was cost per patient. For the long-term analysis, outcomes were presented as QALYs. Costs and effects were discounted at 3% per year.

Results: Over the first 60 days of treatment, prospective screening prior to abacavir initiation cost an additional $US17 per patient and avoided 537 HSRs per 10 000 patients. The per-patient cost of screening was sensitive to the cost of the genetic test, HSR costs and screening performance.
