Background Human cytomegalovirus (HCMV) is involved in complications on immunocompromised patients. 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. Conclusion These results provide a promising search path for potential bitherapies against HCMV.

Cidofovir is a broad-spectrum antiviral agent that has shown efficacy against skin lesions caused by human papillomavirus (HPV). We present a case of extensive verruca vulgaris lesions refractory to imiquimod that was responsive to topical cidofovir therapy, and analyze other case series in the literature of successful treatment of benign HPV-associated skin lesions with topical cidofovir. Topical cidofovir’s favorable response rate and tolerability make it a useful treatment option for patients of differing ages and immune status who have nonmalignant HPV-associated skin lesions and desire topical therapy.

BACKGROUND: The biological processes associated with post-acute sequelae of SARS-CoV-2 infection (PASC) are unknown. 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). These differences were more pronounced among those with a greater number of PASC symptoms. CONCLUSIONS: Persistent immune activation may be associated with ongoing symptoms following COVID-19. Further characterization of these processes might identify therapeutic targets for those experiencing PASC.

BACKGROUND This Phase I, two-part, first-in-human study assessed safety/tolerability and pharmacokinetics/pharmacodynamics of single-ascending doses (SAD) and multiple doses (MD) of the oral toll-like receptor-7 agonist, JNJ-64794964 (JNJ-4964) in healthy adults. METHODS In the SAD phase, participants received JNJ-4964 0.2 (N = 6), 0.6 (N = 6), 1.25 (N = 8) or 1.8 mg (N = 6) or placebo (N = 2/dose cohort) in a fasted state. Food effect was evaluated for the 1.25 mg cohort following ≥6 weeks washout. In the MD phase, participants received JNJ-4964 1.25 mg (N = 6) or placebo (N = 2) weekly (fasted) for 4 weeks. Participants were followed-up for 4 weeks. RESULTS No serious adverse events (AEs) occurred. 10/34 (SAD) and 5/8 (MD) participants reported mild-to-moderate (≤Grade 2), transient, reversible AEs possibly related to JNJ-4964. Five (SAD) participants had fever/flu-like AEs, coinciding with interferon-α serum levels ≥100 pg/mL and lymphopenia (<1 × 109/L), between 24-48 h after dosing and resolving approximately 96 h after dosing. One participant (MD) had an asymptomatic Grade 1 AE of retinal exudates (cotton wool spots) during follow-up, resolving 6 weeks after observation. JNJ-4964 exhibited dose-proportional pharmacokinetics, with rapid absorption (tmax 0.5-0.75 h) and distribution, and a long terminal half-life (150-591 h). Overall, no significant differences in JNJ-4964 pharmacokinetic parameters were observed in the fed versus fasted state. JNJ-4964 dose-dependently and transiently induced cytokines with potential anti-HBV activity, including interferon-α, IP-10, IL-1 RA, and/or MCP-1, and interferon-stimulated genes (ISG15, MX1, and OAS1) in serum. CONCLUSIONS In healthy adults, JNJ-4964 was generally well-tolerated, exhibited dose-proportional pharmacokinetics and induced cytokines/ISGs, with possible anti-HBV activity.

The ongoing COVID-19 pandemic is rapidly reshaping the organization of healthcare systems worldwide, prompting the creation of COVID-19–dedicated wards and services at the expense of pre-existing structures. 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.

INTRODUCTION Doravirine (DOR) is a novel non-nucleoside reverse transcriptase inhibitor (NNRTI) that retains activity against common NNRTI resistance mutations. In this study, we aimed to investigate the prevalence of DOR resistance mutations compared with that of resistance mutations for other NNRTIs among HIV-1-infected treatment-experienced and -naïve patients from Poland. METHODS Resistance to DOR and other NNRTIs was assessed in two datasets: 1760 antiretroviral treatment-naïve HIV-1 patients and 200 treatment-experienced patients. All 1960 sequences were derived from the patients using bulk sequencing. For resistance analyses, Stanford HIV drug resistance database scores were used. RESULTS Overall, DOR resistance was present in 32 patients (1.62%), of whom 13 (0.74%) were naïve and 19 (9.50%) were treatment-experienced. The most common DOR resistance mutations observed among the naïve patients were A98G and K101E (0.2% each), and those among cART-experienced patients were L100I (2.0%), K101E, V108I, H221Y, and P225H (1.5% each). Furthermore, among the naïve patients, less common resistance to DOR (0.7%) compared with that to nevirapine (NVP) (2.1%; p = 0.0013) and rilpivirine (5.40%; p < 0.0001) was observed. For sequences obtained from treatment-experienced patients, the frequency of resistance to DOR (9.5%) was lower than that for efavirenz (25.5%; p < 0.0001) and NVP (26.0%; p < 0.0001). CONCLUSIONS The frequency of transmitted drug resistance to DOR is low, allowing for effective treatment of antiretroviral treatment-naïve patients and rapid treatment initiation. In cART-experienced patients, this agent remains an attractive NNRTI option with a higher genetic barrier to resistance.

In cART-experienced patients, this agent remains an attractive NNRTI option with a higher genetic barrier to resistance.","PeriodicalId":8364,"journal":{"name":"Antiviral Therapy","volume":"26 3-5 1","pages":"69-78"},"PeriodicalIF":1.2,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44437671","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}

Oseltamivir is an orally administered antiviral medication that selectively inhibits the influenza neuraminidase enzymes that are essential for viral replication and it is active against both influenza A and B viruses. Oseltamivir is indicated for therapy or post-exposure prevention of influenza A and B. Side effects are uncommon and include mild nausea, gastrointestinal upset, dizziness, and headache. Despite widespread use, oseltamivir has not been associated with clinically apparent liver injury; however, there is growing evidence of possible toxic liver involvement during oseltamivir therapy. To the best of our knowledge, this is the first reported case in Italy linking the development of acute hepatitis and oseltamivir therapy, in a patient suffering from influenza H1N1 infection. We also present a review of the literature on cases of oseltamivir hepatotoxicity, through the consultation of PubMed database, the bibliographical references of various articles and an extensive search using Google. In view of the analyzed results, we suggest that experts should carefully consider the need for inclusion of potential serious liver reactions be added to the oseltamivir product label.

BACKGROUND Primary analysis at 24 weeks showed that switching to rilpivirine plus darunavir/cobicistat was non-inferior to continuing a standard three-drug antiretroviral regimen in virologically suppressed people with HIV. We present efficacy and safety data from the 48-week analysis. METHODS PROBE 2 is a randomized, open-label trial. Adults who were on a three-drug therapy and had had <50 HIV-1 RNA copies/mL for at least 6 months were randomly assigned (1:1) to 25 mg rilpivirine plus 800/150 darunavir/cobicistat once daily (early switch group) or to continue their regimen for 24 weeks before switching (late switch group). In the 48-week analysis, the efficacy endpoint was the proportion of participants with <50 copies/mL of HIV-RNA (US Food and Drug Administration snapshot algorithm). The trial is registered with ClinicalTrials.gov, number NCT04064632. FINDINGS 160 participants were recruited and randomized. At week 48, 70 (87.5%) in the early switch group and 76 (94.8%) in the late switch group maintained HIV-RNA <50 copies/mL. Virological failure (≥50 HIV-RNA copies/mL) was not seen in any patient of the early switch group and in 2 subjects in the late switch group none of which had treatment emergent resistance-associated mutation. 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. INTERPRETATION The 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.

BACKGROUND Doravirine (DOR) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) approved for HIV-1 infection treatment. Because of its genetic barrier, DOR appears to be a good alternative in switch strategies compared to other NNRTI. Our aim was to evaluate the percentage of people living with HIV (PLWHIV) followed in our center who could be eligible to a DOR-based regimen. METHODS We collected data from all treatment-experienced PLWHIV, never exposed to DOR and with a demonstrated virological suppression. We analyzed previous genotypic analyses, clinical history, and previous exposure to NNRTIs. RESULTS We analyzed data from 653 patients, whose characteristics are shown in Table 1. 59% of them presented no resistance mutation (RAM) at genotypic analysis. The most common DOR-related RAM were V106A, Y181V, and Y188L. We also analyzed RAM that can possibly interfere with combination therapy (mostly K65R and M184V). In the end, 81.8% of our patients results to be eligible for a DOR-based therapy regimen. CONCLUSIONS DOR represents a good option for switch strategies in virological suppressed PLWHIV. It seems to have a higher genetic barrier and a lower risk for resistance mutation development compared to other NNRTI. In our cohort, we found 81.8% of patients who could be eligible for a regimen containing DOR and almost 2/3 of patients who can be treated with the fixed-dose combination DOR/3TC/TDF.

The morbidity and mortality of people living with HIV (PLWH) has decreased markedly after the introduction of highly effective antiretroviral therapy (ART). The safety profile of drugs used for HIV has improved over time, and nowadays, co-formulated combinations with excellent tolerability are available. One of the most commonly used is elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (EVG/COBI/FTC/TAF) due to its effectiveness in viral suppression and good tolerability [1-2]. PLWH are at greater risk of suffering hepatobiliary complications, not only caused by opportunistic infections or AIDS cholangiopathy related to advanced immunosuppression but also due to drug-induced hepatotoxicity, use of alcohol or other substances, coinfections with hepatitis virus or liver steatosis [3]. This article describes a case of a patient who developed a severe increase in cholestasis parameters after starting EVG/COBI/FTC/TAF regimen, probably related to integrase strand transfer inhibitor (InSTI). Liver enzyme elevation during InSTI-based therapy is an unusual finding. To our knowledge, this is the first report in the literature of EVG/COBI/FTC/TAF-associated cholestasis. The article tries to generate knowledge in order to strengthen pharmacovigilance of this adverse effect and reviews the available data on cholestasis in PLWH.
