The primary objective of this review was to evaluate the antiviral efficacy of co-formulated abacavir-lamivudine-zidovudine for initial treatment of HIV infection. The secondary objectives were to evaluate the safety and tolerability of the triple drug combination. We identified 15 potentially eligible studies, four of which met our inclusion criteria. Our findings indicate that co-formulated abacavir-lamivudine-zidovudine remains a viable option for initiating antiretroviral therapy, especially in HIV-infected patients with pre-existing hyperlipidaemia and those who do not tolerate ritonavir.

    • "Both text words and medical subject heading (MeSH) terms, for example abacavir, antiretroviral, HIV, acquired immunodeficiency syndrome, child, paediatric, adolescent and randomised controlled trial will be used in the search strings. We will use these terms in different combinations with the adaptation of the literature search strategy to suit each database (see Additional file 1 for the proposed search strategy adapted from Shey et al. [19]). "

    ABSTRACT: Background: Abacavir is one of the recommended nucleoside reverse transcriptase inhibitors (NRTIs) for the treatment of HIV infections among children and adolescents. However, there are concerns that the antiviral efficacy of abacavir might be low when compared to other NRTIs especially among children. There are also concerns that abacavir use may lead to serious adverse events such as hypersensitivity reactions and has potential predisposition to developing cardiovascular diseases. Methods: We plan to do a systematic review to evaluate the antiviral efficacy and safety of abacavir-containing combination antiretroviral therapy as first-line treatment of HIV-infected children aged between 3 months and 18 years, compared with other NRTIs. We will search Scopus, Cochrane Central Register of Controlled Trials, MEDLINE, and Web of Science databases for eligible studies regardless of language or publication status. We will check the reference lists of included studies, search relevant conference proceedings, email the authors of included studies and also look for unpublished and ongoing trials in prospective clinical trial registries. Two authors will independently screen search outputs, select studies, extract data and assess the risk of bias in included studies. All disagreements will be resolved by discussion and consensus. Where data allow, we will conduct meta-analysis for similar types of participants, study designs, interventions, and outcome measures. If the results are statistically homogeneous, we will use the fixed-effect model; otherwise, we will use the random-effects model and explore the reasons for heterogeneity using subgroup analyses. Heterogeneity will be assessed with the Chi-squared test and quantified with the I-squared statistic. Discussion: The findings will be useful to policy makers and programme managers to inform treatment and management of HIV in children and adolescents and to point out research gaps for future research. Trial registration: This review is registered with PROSPERO, registration number CRD42014009157.

    ABSTRACT: Drug repositioning is one of the most rapidly emerging fields of study. This concept is anchored on the principle that diseases have similar damaged or affected signaling pathways. Recently, drugs have been repositioned not only for their alternative therapeutic uses but also for their applications as biomaterials in various fields. However, medical drugs as biomaterials are rarely focused on in reviews. Fragmin and protamine have been recently the sources of increasing attention in the field of tissue engineering and regenerative medicine. Fragmin and protamine have been manufactured primarily as a safe antidote for the circulating heparin. Lately, these drugs have been utilized as either micro- or nanoparticle biomaterials. In this paper, we will briefly describe the concept of drug repositioning and some of the medical drugs that have been repurposed for their alternative therapeutic uses. Also, this will feature the historical background of the studies focused on fragmin/protamine micro/nanoparticles (F/P M/NPs) and their applications as biomaterials in tissue engineering, stem cell therapy, and regenerative medicine.
