Abstract

<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d14045042e188">Point-of-care hepatitis C virus (HCV) RNA testing can facilitate single-visit diagnosis and treatment. This study evaluated a single-visit test and treat intervention integrating point-of-care HCV RNA testing, linkage to nursing care, and peer-supported engagement/delivery of treatment among people with recent injecting drug use at a peer-led needle and syringe program (NSP). </p>

Prospective comparison of transient elastography, Fibrotest, APRI, and liver biopsy for the assessment of fibrosis in chronic hepatitis C.

Laurent Castéra, Julien Vergniol, Juliette Foucher … (2005)

Transient elastography (FibroScan; Echosens, Paris, France) is a novel, noninvasive, and rapid bedside method to assess liver fibrosis by measuring liver stiffness. We prospectively assessed the performance of FibroScan in patients with chronic hepatitis C, in comparison with and combined with currently available biochemical markers (Fibrotest; Biopredictive; and the aspartate transaminase to platelets ratio index [APRI]); a liver biopsy examination performed the same day served as the reference. We studied 183 consecutive patients with chronic hepatitis C (METAVIR fibrosis stage F1, n = 47; F2, n = 53; F3, n = 37; F4, n = 46). FibroScan values ranged from 2.4 to 75.4 kilopascals (median, 7.4 kilopascals). Cut-off values were 7.1 kPa for F > or = 2, 9.5 kPa for F > or = 3, and 12.5 kPa for F = 4. The areas under the receiver operating characteristic (ROC) curve of FibroScan, FibroTest, and APRI values were of the same order (.83, .85, and .78, respectively, for F > or = 2; .90, .90, and .84, respectively, for F > or = 3; and .95, .87, and .83, respectively, for F = 4). The best performance was obtained by combining the FibroScan and FibroTest, with areas under the ROC curve of .88 for F > or = 2, .95 for F > or = 3, and .95 for F = 4. When the FibroScan and FibroTest results agreed, liver biopsy examination confirmed them in 84% of cases for F > or = 2, in 95% for F > or = 3, and in 94% for F = 4. FibroScan is a simple and effective method for assessing liver fibrosis, with similar performance to FibroTest and APRI. The combined use of FibroScan and FibroTest to evaluate liver fibrosis could avoid a biopsy procedure in most patients with chronic hepatitis C.

Effectiveness of peer education interventions for HIV prevention in developing countries: a systematic review and meta-analysis.

Kevin O'Reilly, Michael Sweat, Amy Medley … (2009)

Peer education for HIV prevention has been widely implemented in developing countries, yet the effectiveness of this intervention has not been systematically evaluated. We conducted a systematic review and meta-analysis of peer education interventions in developing countries published between January 1990 and November 2006. Standardized methods of searching and data abstraction were utilized. Merged effect sizes were calculated using random effects models. Thirty studies were identified. In meta-analysis, peer education interventions were significantly associated with increased HIV knowledge (odds ratio [OR]: 2.28; 95%, confidence interval [CI]:1.88, 2.75), reduced equipment sharing among injection drug users (OR: 0.37; 95% CI: 0.20, 0.67), and increased condom use (OR: 1.92; 95% CI: 1.59, 2.33). Peer education programs had a nonsignificant effect on sexually transmitted infections (OR: 1.22; 95% CI:0.88, 1.71). Meta-analysis indicates that peer education programs in developing countries are moderately effective at improving behavioral outcomes but show no significant impact on biological outcomes. Further research is needed to determine factors that maximize the likelihood of program success.
