Methods RPV-treated HIV-infected patients from phase 2b or 3 studies rolled-over into this phase 3, open-label study and received RPV 25 mg once daily (QD) with choice of two NRTIs. Adverse events (AEs), plasma viral load, CD4+ cell count, and antiviral resistance were evaluated. Results Of the 482 patients treated, 437 (>90%) patients discontinued study treatment; 371 (77%) had switched to commercially available RPV, 14 (2.9%) discontinued due to AEs, and 6 (1.2%) had virologic failure. In this rollover study, patients were followed up to week 336, although data was limited beyond 288 weeks. Forty-five (9.3%) patients were still undergoing treatment at the time of data cut-off for the current analysis (8 February 2018). The most frequently reported AEs were pregnancy in 7 (1.5%) patients and syphilis in 5 (1.0%) patients. Grade 3–4 AEs were reported in 17 (3.5%) patients, and AEs possibly related to RPV in 23 (4.8%) patients. Over 288 weeks of treatment, 80.1% (95% CI: 74.9%; 84.3%) of patients maintained virologic suppression (HIV-1 RNA <50 copies/mL). The absolute CD4+ cell count increased over time until week 192 and remained constant thereafter. Conclusions RPV 25 mg QD in combination with an investigator-selected background regimen of two NRTIs demonstrated sustained long-term virologic suppression. The treatment was well-tolerated with no new safety findings.","PeriodicalId":8364,"journal":{"name":"Antiviral Therapy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45063080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We determined changes in liver stiffness measure (LSM) using transient elastography over 6 years in HIV mono-infected and HIV-HBV co-infected Nigerians initiating antiretroviral therapy (ART) and factors associated with LSM decline. Methods This single centre, cohort study enrolled ART-naïve HIV mono- and HIV-HBV co-infected adults (≥18 years) at the APIN Public Health Initiatives–supported HIV Care and Treatment Centre at Jos University Teaching Hospital, Nigeria, from 7/2011 to 2/2012. LSM at baseline, Years 3 and 6 were analysed using longitudinal models to estimate changes over time and their predictors. Results Data from 100 (31%) HIV-HBV co-infected and 225 (69%) HIV mono-infected participants were analysed. Median LSM at baseline was 6.10 (IQR: 4.60–7.90) kPa in co-infected and 5.10 (IQR: 4.40–6.10) kPa in mono-infected participants. In adjusted analyses, average LSM was not significantly different between Year 0 and 3 (β = 0.02, −0.22 to 0.26, p = 0.87 and Year 0 and 6 (β = −0.02, −0.23 to 0.27, p = 0.88) in both groups (p>0.05), but co-infected participants had significantly higher LSM than mono-infected throughout follow-up (β = 0.018, 0.019–0.28, p < 0.001). Year 3 LSM differed according to ART initiation status by Year 3 (initiators - non-initiators: −0.87, −1.70 to −0.29). Conclusion In this cohort, LSM remained higher among HIV-HBV co-infected versus HIV mono-infected participants throughout follow-up. Our findings emphasize the continuing need for monitoring of liver outcomes in HIV-HBV co-infected populations on ART and the importance of preventing HBV infection among PLH to optimize liver health.","PeriodicalId":8364,"journal":{"name":"Antiviral Therapy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46096286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current therapeutics are associated with several drawbacks, such as nephrotoxicity. Purpose: As HCMV infection affects inflammation pathways, especially prostaglandin E2 (PGE2) production via cyclooxygenase 2 enzyme (COX-2), we designed 2'-hydroxychalcone compounds to inhibit human cytomegalovirus. Study design We first selected the most efficient new synthetic chalcones for their effect against COX-2-catalyzed PGE2. Study sample Among the selected compounds, we assessed the antiviral efficacy against different HCMV strains, such as the laboratory strain AD169 and clinical strains (naïve or multi-resistant to conventional drugs) and toxicity on human cells. Results The most efficient and less toxic compound (chalcone 7) was tested against HCMV in combination with other antiviral molecules: artesunate (ART), baicalein (BAI), maribavir (MBV), ganciclovir (GCV), and quercetin (QUER) using Compusyn software. Association of chalcone 7 with MBV and BAI is synergistic, antagonistic with QUER, and additive with GCV and ART.

METHODS: We measured soluble markers of inflammation in a SARS-CoV-2 recovery cohort at early (<90 days) and late (>90 days) timepoints. We defined PASC as the presence of one or more COVID-19-attributed symptoms beyond 90 days. We compared fold-changes in marker values between those with and without PASC using mixed effects models with terms for PASC and early and late recovery time periods. RESULTS: During early recovery, those who went on to develop PASC generally had higher levels of cytokine biomarkers including TNF-alpha (1.14-fold higher mean ratio, 95%CI 1.01-1.28, p=0.028) and IP-10 (1.28-fold higher mean ratio, 95%CI 1.01-1.62, p=0.038). Among those with PASC, there was a trend toward higher IL-6 levels during early recovery (1.28-fold higher mean ratio, 95%CI 0.98-1.70, p=0.07) which became more pronounced in late recovery (1.44-fold higher mean ratio, 95%CI: 1.11-1.86, p<0.001).

European countries are now facing the “second wave” of the COVID-19 epidemic, with increasing numbers of cases and deaths; hence, people with chronic conditions, including those living with HIV (PLWHIV), are struggling to maintain their routine disease management, resulting in missed medical visits and the risk of lower adherence to treatment. In our clinical center in Rome, Italy, we conducted a retrospective study aimed at observing how PLWHIV were followed-up during the “first wave” of the COVID-19 epidemic in the country and during the national lockdown from March 9 to May 28, 2020. We analyzed all treatment-experienced, virologically suppressed PLWHIV who had had at least one visit between March 10 and June 1, 2020, and collected viroimmunological parameters. We compared this group of PLWHIV with the patients observed over the same period in 2019. Our primary aim was to assess the rate of virological failures (VF, defined as two consecutive HIVRNA ≥ 50 copies/mL or a single HIV-RNA ≥ 1000 copies/mL). Predictors of VF were assessed using Cox regression analysis. Regarding the 2020 group, data from 341 patients were analyzed: 235 (68.9%) were males, with a median age of 54 years (Interquartile range = 46–60), a median time from HIV diagnosis of 16.1 years (IQR = 7.6–23.8), and a median time of virological suppression of 82.4 months (IQR = 31.1–142.9). With regard to antiretroviral therapy, 149 patients (43.7%) were on a 2NRTI+INI regimen, 74 (21.7%) were on 2NRTI+NNRTI, 70 (20.5%) were on a dual regimen with DTG+3 TC, 22 (6.5%) were on a regimen with 2NRTI+bPI, and 26 (7.6%) were on other regimens. Regarding the 2019 group, data from 1066 patients were available. All patients’ characteristics and differences between groups are shown in Table 1. During 184.3 Patient-Years of Follow-Up (PYFU) of the 2020 group, we observed 23 VF, a rate of 12.5 per 100 PYFU. In patients experiencing VF, we performed a genotypic test to investigate acquired mutations: among the 23 analyzed individuals, two of them, both on a 2NRTI+raltegravir (RAL) strategy, presented newly discovered mutations (one had both the 138K and the 148R mutations and the other had the 155H mutation) conferring resistance to RAL. Interestingly, patients on a dual regimen had significantly less probability of showing VF compared to patients on 3+ drug regimens: 6-month probability of remaining virologically suppressed was 98.8% vs 90.5%, respectively (log-rank p = 0.031). In the calendar period of 2019, we observed 50 VF during 675 PYFU, a rate of 7.4 per 100 PYFU.

Adverse events leading to treatment discontinuation occurred in 7 (8.7%) participants in the early switch group and in none in the late switch group.\u0000\u0000\u0000INTERPRETATION\u0000The combination of rilpivirine plus darunavir/cobicistat sustained virological suppression, was associated with a low frequency of virological failure, and had a favorable safety profile, which support its use as a nucleoside reverse transcriptase inhibitor-sparing and integrase inhibitor-sparing alternative to three-drug regimens.","PeriodicalId":8364,"journal":{"name":"Antiviral Therapy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49614569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
