Pediatric human immunodeficiency virus (HIV) care in resource-limited settings remains a major challenge to achieving global HIV treatment and virologic suppression targets, in part because the administration of combination antiretroviral therapies (cART) is inherently complex in this population and because viral load and drug resistance genotyping are not routinely available in these settings. Children may also be at elevated risk of transmission of drug-resistant HIV as a result of suboptimal antiretroviral administration for prevention of mother-to-child transmission. We investigated the prevalence and the correlates of pretreatment HIV drug resistance (PDR) among HIV-infected, cART-naive children in Ethiopia. We observed an overall PDR rate of 14%, where all cases featured resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs): ~9% of participants harbored resistance solely to NNRTIs while ~5% harbored resistance to both NNRTIs and nucleoside reverse transcriptase inhibitors (NRTIs). No resistance to protease inhibitors was observed. No sociodemographic or clinical parameters were significantly associated with PDR, though limited statistical power is noted. The relatively high (14%) rate of NNRTI resistance in cART-naive children supports the use of non-NNRTI-based regimens in first-line pediatric treatment in Ethiopia and underscores the urgent need for access to additional antiretroviral classes in resource-limited settings.

Introduction: The present study aimed to report the prevalent HIV-1 drug-resistant mutations in patients with HIV-1 alone and tuberculosis (TB) coinfection alone to improve our understanding of the mutation patterns and aid treatment decisions. Methods: Patients with HIV-1 and HIV-TB on treatment for more than 1 year with suspected failure were recruited. Sequencing of protease and two-thirds of the region of reverse transcriptase gene was done for drug-resistant mutations. Results: In the HIV-TB group (n = 25), 88%, 92%, and 12% had mutations to nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), and protease inhibitors (PIs), respectively. In the HIV-alone group (n = 25), 84%, 100%, and 4% had mutations to NRTIs, NNRTIs, and PIs, respectively. M184V, M41L, D67N, G190A, A98G, and K103N were the most common mutations seen. Conclusion: There is a high prevalence of drug-resistant mutations in HIV and HIV-TB coinfected patients.

Abstract Background Of 8 formulary HIV medications at our institution, 3 are no longer first line treatments. Agents unavailable on formulary are administered from a patient’s own supply. We examined the impact of availability of antiretroviral therapy (ART) on time to appropriate therapy among HIV positive inpatients. Methods Adult inpatients who received ART from 11/2015 – 10/2016 were included in this single-center review. Data were evaluated by encounter; individuals with multiple admissions were counted per admit. Descriptive statistics were used to evaluate the time from admission to ART order and administration. We noted discrepancies between ordered and home ART regimen, and any administration of partial therapy. Patients not taking ART prior to admission or without documentation of a home ART regimen were excluded from the outcomes analysis. A cost analysis was conducted to describe the financial impact of any recommended formulary changes. Results 36 patients with 55 inpatient encounters were evaluated; 46 (84%) had a documented home ART regimen. Mean age was 47.8 years, 67% were male, 36% met criteria for AIDS by CD4 cell count. Creatinine clearance was < 60 ml/minute in 33% of subjects, 25% were admitted for an infectious issue. Median length of stay was 5 days. Half (49%) were taking nucleoside reverse transcriptase inhibitors, 22% integrase inhibitors, 19% protease inhibitors, 3% non-nucleoside reverse transcriptase inhibitors. In the 7 encounters (15%) with all ART on formulary, 100% received their full ART regimens as inpatients vs. 69% of those with partial or no ART on formulary. Median time to therapy doubled in patients who had partial or no home ART on formulary: 25 hours (median of 1 missed dose) vs.. 12 hours (median of 0 missed doses). Anticipated annual cost of formulary revisions, including addition of 4 agents, was $6016.37. Conclusion Having a complete ART regimen on formulary substantially increased likelihood of complete ART administration without delay. Adding an NRTI alternative to tenofovir was needed due to high rates of renal dysfunction; adding agents with higher barriers to resistance, dolutegravir and darunavir, were important as genotypes and viral loads are not always known at admit. Expanding the ART formulary provides a significant improvement in quality of care at a reasonable cost. Disclosures All authors: No reported disclosures.

IntroductionHIV (human immunodeficiency virus) infection is related to several neuropsychiatric complications, such as dementia, encephalopathy, psychosis, as well as, opportunistic infections of the central nervous system (CNS). The discovery of antiretroviral therapy (ART) has limited these conditions and extended the life span of infected patients into a chronic illness, but it is also associated with neuropsychiatric adverse effects.ObjectivesTo review the literature on the most common neuropsychiatric complications of the ART, since it can be difficult to distinguish drugs toxicity, the effects of the virus, immune system and psycho-social events.MethodsThe authors have conducted an online search in PubMed with the terms: “Psychiatry”, “HIV”, “adverse effects” and “antiretroviral drugs” from 2011 until 2016. From the outcome were collected, analyzed and summarized the articles considered to be relevant.ResultsThe antiretroviral therapy (ART) are associated with a numerous adverse effects on the central and peripheral nervous systems, as well as, metabolic, gastrointestinal, cardiac, and other toxicities. The neuropsychiatric effects are common and highly variable, including depression, cognitive impairment and sleep disturbance. The nucleoside reverse transcriptase inhibitors and the non-nucleoside reverse transcriptase inhibitors are one of the two classes of antiviral drugs most frequently associated with neuropsychiatric complications.ConclusionsThe occurrence of new-onset conditions related to ART makes it difficult to determine the association between psychiatric disorders and ART adverse effects, and given the fact that patients commit to lifelong therapy, as well as, they can diminish quality of life; it makes these assessment important in treating these conditions.Disclosure of interestThe authors have not supplied their declaration of competing interest.
