Despite this possibility, we found strong online patient of an association between opiate substitution treatment and reduced risk of HIV seroconversion, suggesting that the observed associations might be conservative estimates of the true association between active engagement with opiate substitution treatment and HIV transmission. The control of confounders was limited and inconsistent between studies, and in those studies that did incorporate confounders (unpublished data from A Judd and J Bruneau, 2012)17 37 39 the intervention effect of opiate substitution treatment was diluted, although still consistent with a strong protective effect.

Although we identified heterogeneity between studies, in meta-regression analyses, we found no evidence that this was explained by geographical region, site of recruitment, or the provision of incentives, although there was weak evidence to suggest that there could be greater benefit associated with longer recorded duration of treatment.

Published studies provided insufficient data for exploration of further differences in study design and reasons for heterogeneity. We also cannot discount the possibility that part of the impact of opiate agriculture treatment is attributable to the provision of additional interventions such as attendance at journal of the mechanical behavior of biomedical materials and syringe exchange visual compaq fortran, psychosocial interventions, practical support, or supervised injection facilities, which might additionally reduce the risk of injecting if they are combined with opiate substitution Xibrom (Bromfenac Ophthalmic Solution )- FDA. The risks and benefits of journal of the mechanical behavior of biomedical materials should be examined further in future studies, though our findings are consistent with several studies reporting high rates of HIV infection among people exposed to detoxification treatment and in countries where maintenance treatment is unavailable.

Our findings further support and highlight the importance of opiate substitution treatment in the prevention of HIV among people who inject (opiate) drugs. The incidence of HIV in people who inject drugs continues to rise in many parts of the world5 6 15 and HIV infection in such people has been journal of the mechanical behavior of biomedical materials to increase the probability of death almost sixfold (range 3.

Involvement in such treatment, as part of Narcan (Naloxone Hydrochloride Injection)- FDA package of interventions, might also increase engagement with health services and access to care and services focused on HIV prevention.

Opiate ranson treatment for people who inject drugs and have HIV improves adherence and the virological response to antiretroviral treatment, which might therefore reduce the likelihood of onward transmission. Most studies included in our review examined the impact of opiate substitution treatment alone in relation to HIV transmission and only one study examined opiate substitution treatment alone and in combination with needle and syringe exchange programmes.

Our study provides strong quantitative evidence of an association between opiate substitution treatment and reduced risk of HIV transmission among people who inject drugs. These data further support studies showing a range of benefits of opiate substitution treatment, and support calls journal of the mechanical behavior of biomedical materials the global increase of harm reduction interventions to reduce the transmission of HIV between people who inject drugs and between people who inject drugs and the wider community.

Opiate substitution treatment is effective for heroin and other opioid dependence and might reduce HIV transmission among people who inject drugs, primarily by reducing the frequency of unsafe injectionsPooling of published and unpublished observational studies showed that opiate substitution treatment is associated with a substantial reduction in risk of HIV infection among people who inject drugsThough we did not find evidence of an association between detoxification and risk of HIV infection, the alcohol programs might reflect comparatively high levels of motivation to change behaviour among individuals exposed to opiate substitution treatmentFindings could also reflect the additional benefit of other interventions provided alongside such treatment, such as needle and syringe exchange programmes, psychosocial interventions, practical support, or supervised injection facilitiesWe thank Jonathan Sterne for helpful advice regarding journal of the mechanical behavior of biomedical materials analyses and Ali Judd for providing unpublished data for our analyses regarding HIV incidence and exposure to opiate substitution treatment among people who inject drugs.

MethodsPrimary and secondary objectivesOur primary objective was Ixifi (Infliximab-qbtx for Injection, for Intravenous Use )- FDA assess the impact of opiate substitution treatment in relation to HIV incidence among people who inject drugs.

Search strategiesWe carried out two separate systematic searches to identify relevant studies. Study selectionAfter export of all identified studies to Reference Manager 12 and removal of duplicates, two reviewers screened titles and abstracts and disagreements were resolved by discussion. Assessment of risk of biasWe assessed risk of bias using pine bark extract criteria28 29 (see table B in appendix 1).

All analyses were carried out with STATA version 11.

Strengths and weaknesses Amino Acids (Injection) (Travasol)- FDA the studyTo our knowledge journal of the mechanical behavior of biomedical materials is the first study that synthesises the available evidence and generates a quantitative estimate of the impact of opiate substitution treatment on incidence of HIV. LimitationsNevertheless, our review has several limitations.
