Hepatic profile analyses of tipranavir in Phase II and III clinical trials
<p>Abstract</p> <p>Background</p> <p>The risk and course of serum transaminase elevations (TEs) and clinical hepatic serious adverse event (SAE) development in ritonavir-boosted tipranavir (TPV/r) 500/200 mg BID recipients, who also received additional combination antiretroviral treatment agents in clinical trials (TPV/r-based cART), was determined.</p> <p>Methods</p> <p>Aggregated transaminase and hepatic SAE data through 96 weeks of TPV/r-based cART from five Phase IIb/III trials were analyzed. Patients were categorized by the presence or absence of underlying liver disease (+LD or -LD). Kaplan-Meier (K-M) probability estimates for time-to-first US National Institutes of Health, Division of AIDS (DAIDS) Grade 3/4 TE and clinical hepatic SAE were determined and clinical actions/outcomes evaluated. Risk factors for DAIDS Grade 3/4 TE were identified through multivariate Cox regression statistical modeling.</p> <p>Results</p> <p>Grade 3/4 TEs occurred in 144/1299 (11.1%) patients; 123/144 (85%) of these were asymptomatic; 84% of these patients only temporarily interrupted treatment or continued, with transaminase levels returning to Grade ≤ 2. At 96 weeks of study treatment, the incidence of Grade 3/4 TEs was higher among the +LD (16.8%) than among the -LD (10.1%) patients. K-M analysis revealed an incremental risk for developing DAIDS Grade 3/4 TEs; risk was greatest through 24 weeks (6.1%), and decreasing thereafter (>24-48 weeks: 3.4%, >48 weeks-72 weeks: 2.0%, >72-96 weeks: 2.2%), and higher in +LD than -LD patients at each 24-week interval. Treatment with TPV/r, co-infection with hepatitis B and/or C, DAIDS grade >1 TE and CD4<sup>+ </sup>> 200 cells/mm<sup>3 </sup>at baseline were found to be independent risk factors for development of DAIDS Grade 3/4 TE; the hazard ratios (HR) were 2.8, 2.0, 2.1 and 1.5, respectively. Four of the 144 (2.7%) patients with Grade 3/4 TEs developed hepatic SAEs; overall, 14/1299 (1.1%) patients had hepatic SAEs including six with hepatic failure (0.5%). The K-M risk of developing hepatic SAEs through 96 weeks was 1.4%; highest risk was observed during the first 24 weeks and decreased thereafter; the risk was similar between +LD and -LD patients for the first 24 weeks (0.6% and 0.5%, respectively) and was higher for +LD patients, thereafter.</p> <p>Conclusion</p> <p>Through 96 weeks of TPV/r-based cART, DAIDS Grade 3/4 TEs and hepatic SAEs occurred in approximately 11% and 1% of TPV/r patients, respectively; most (84%) had no significant clinical implications and were managed without permanent treatment discontinuation. Among the 14 patients with hepatic SAE, 6 experienced hepatic failure (0.5%); these patients had profound immunosuppression and the rate appears higher among hepatitis co-infected patients. The overall probability of experiencing a hepatic SAE in this patient cohort was 1.4% through 96 weeks of treatment. Independent risk factors for DAIDS Grade 3/4 TEs include TPV/r treatment, co-infection with hepatitis B and/or C, DAIDS grade >1 TE and CD4<sup>+ </sup>> 200 cells/mm<sup>3 </sup>at baseline.</p> <p>Trial registration</p> <p>US-NIH Trial registration number: NCT00144170</p
The Perspectives And Practices Of Female Genital Mutilation Among Women Accessing Out-Patient Services At The University Of Nigeria Teaching Hospital, Enugu, South East Nigeria
Context: Female genital mutilation is a gender based harmful practice that exposes women and the girl child to medical and obstetric complications. Accurate information is necessary for its eradication.
Method:
A cross-sectional study was conducted among 100 women aged 15-60 years at the University of Nigeria Teaching Hospital, Enugu State, Nigeria. A systematic sampling method was used in the selection of the study subjects. A pre-tested, semi-structured, interviewer-administered questionnaire was used to assess their knowledge, attitude and practice toward female genital mutilation (FGM).
Result
Eight five (85.0%) of the respondents were aware of the ongoing campaign against female
genital mutilation but the in depth knowledge was poor. Fifty-three (53.0%) and less than 50% understood the true meaning and complications of the FGM respectively. Seventy (70.0%) believed that circumcision is good and should be continued to preserve tradition/custom, 60 (60.0%). Of the eighty-two (82.0%) respondents circumcised, 66 (80.5%) were married. Traditional birth attendants, Nurse-midwives and medical doctors were all involved in this practice.
Conclusion : There is need for more awareness campaign on Female genital mutilation. Keywords: Circumcision, Genital, mutilation, Nigeria , practices. Ebonyi Medical Journal Vol. 7 (1&2) 2008: pp. 14-2
Willingness to pay for community‐based ivermectin distribution: A study of three onchocerciasis‐endemic communities in Nigeria
Schistosomiasis and soil-transmitted helminth control in Niger : cost effectiveness of school based and community distributed mass drug administration
BACKGROUND: In 2004 Niger established a large scale schistosomiasis and soil-transmitted helminths control programme targeting children aged 5–14 years and adults. In two years 4.3 million treatments were delivered in 40 districts using school based and community distribution. METHOD AND FINDINGS: Four districts were surveyed in 2006 to estimate the economic cost per district, per treatment and per schistosomiasis infection averted. The study compares the costs of treatment at start up and in a subsequent year, identifies the allocation of costs by activity, input and organisation, and assesses the cost of treatment. The cost of delivery provided by teachers is compared to cost of delivery by community distributers (CDD). The total economic cost of the programme including programmatic, national and local government costs and international support in four study districts, over two years, was US0.58. The full economic delivery cost of school based treatment in 2005/06 was 0.46. Including only the programme costs the figures are 0.41 respectively. Differences at sub-district are more marked. This is partly explained by the fact that a CDD treats 5.8 people for every one treated in school. The range in cost effectiveness for both direct and direct and indirect treatments is quantified and the need to develop and refine such estimates is emphasised. CONCLUSIONS: The relative cost effectiveness of school and community delivery differs by country according to the composition of the population treated, the numbers targeted and treated at school and in the community, the cost and frequency of training teachers and CDDs. Options analysis of technical and implementation alternatives including a financial analysis should form part of the programme design process
