The aromatic structure and the rich nitrogen content of polymers based on covalent triazine-based frameworks (CTF) and their unique hydrophilic-lipophilic-balanced adsorption properties make them promising candidates for an adsorbent that can be used for sample pretreatment. Herein, a new covalent triazine-based framework (CTF-DBF) synthesized by a Friedel-Crafts reaction was used for the determination of the content of nucleotides in com. infant formula. It was shown that the synthetic materials had an amorphous microporous structure, a BET surface area of up to 595.59 m2/g, and 0.39 nm and 0.54 nm micropores. The versatile adsorption properties of this material were evaluated by quantum chem. theory calculations and batch adsorption experiments using five nucleotides as probes. The quantum chem. results demonstrated that CTF-DBF can participate in multiple interactions with nucleotides. All the analyses performed present good linearity with R2 > 0.9993. The detection limits of targets ranged from 0.3 to 0.5 mg/kg, the spiked recoveries were between 85.8 and 105.3% and the relative standard deviations (RSD, n = 6) were between 1.1 and 4.5%. All these results suggest that this versatile CTF-DBF has great potential for sample pretreatment.

Importance: Ledipasvir-sofosbuvir has become the current standard of care for hepatitis C since its release in 2014. Therefore, potential adverse effects are important to identify. Objective: To report findings of uveitis after treatment with ledipasvir-sofosbuvir for hepatitis C. Design, Setting, and Participants: This case series includes patients treated in an urban academic setting with ledipasvir-sofosbuvir for hepatitis C from June 2015 to June 2017 who are known to have developed signs and symptoms of posterior uveitis. Exposures: All patients had been treated with ledipasvir-sofosbuvir for hepatitis C for a total of 12 weeks. All patients but 1 had finished treatment prior to presentation. Main Outcomes and Measures: Signs of posterior uveitis on ophthalmic testing. Results: Data were collected from 6 patients (median age, 64.5 [range, 54-72] years). Five patients were male; 4 were white, and 2 were African American. The mean (SD) time between beginning of treatment and presentation was 8.8 (5.5) months. Both eyes were affected in 3 of the 6 patients (total, 9 eyes). The median presenting visual acuity in affected eyes was 20/40 (range, 20/20-20/70). All patients had a negative systemic uveitis workup. Five patients presented with blurred vision, and 1 had a paracentral scotoma. The main ocular findings were peripheral vasculitis (in 8 of 9 eyes), papillitis (in 7 of 9 eyes), and cystoid macular edema (in 6 of 9 eyes). The median follow-up was 8 (range, 4-13) months. The median final visual acuity was 20/40 (range, 20/20-20/200). Conclusions and Relevance: In these patients, it appears that treatment with ledipasvir-sofosbuvir for hepatitis C was associated with a mild posterior uveitis different than interferon retinopathy. Given the large number of patients treated with ledipasvir-sofosbuvir, these findings cannot be considered causative, and an association cannot be quantified at this time.

BACKGROUND: Limited treatment data are available for hepatitis C virus (HCV) in sub-Saharan Africa, especially for genotype 4. Our objective was to establish the safety and efficacy of ledipasvir-sofosbuvir for chronic HCV genotype 1 or 4 infection in adults in Rwanda. METHODS: We did a single-arm trial to evaluate the safety and efficacy of ledipasvir-sofosbuvir in Rwandan adults with chronic HCV infection at a single study site (Rwanda Military Hospital, Kigali, Rwanda). We enrolled individuals aged 18 years or older with HCV genotype 1 or 4 infection and a plasma HCV RNA concentration of more than 1000 IU/mL at screening. All participants were given ledipasvir (90 mg) and sofosbuvir (400 mg) in a single combination tablet once daily for 12 weeks. We established HCV genotype using an Abbott platform, and HCV subtype with PCR amplification. The primary endpoint was the proportion of participants with a sustained virological response 12 weeks after therapy (SVR12). All patients enrolled in the study were included in the primary endpoint analyses. This study is registered with ClinicalTrials.gov, number NCT02964091. FINDINGS: 300 participants were enrolled between Feb 6, 2017, and Sept 18, 2017, and the follow-up period was completed on March 1, 2018. On genotyping, 248 (83%) participants were reported as having genotype 4, four (1%) genotype 1, and 48 (16%) both genotype 1 and genotype 4. Subsequent viral sequencing showed all participants actually had genotype 4 infection with subtype 4k (134 [45%]), subtype 4r (48 [16%]), subtype 4q (42 [14%]), and subtype 4v (24 [8%]) predominating. Overall, 261 (87%, 95% CI 83-91) participants achieved SVR12. In participants with genotype 4r, SVR12 was observed in 27 (56%, 95% CI 41-71) participants versus 234 (93%, 90-96) individuals with other subtypes. There were no drug-related treatment discontinuations due to ledipasvir-sofosbuvir. The most common adverse events were hypertension (97 [32%]), headache (78 [26%]), dizziness (61 [20%]), and fatigue (56 [19%]). There were six serious adverse events; none were assessed to be due to the study drug. 296 participants had data for pill counts at week 4 and 8; 271 (92%) had 100% adherence and only one (<1%) had an adherence of less than 90%. INTERPRETATION: This is the first large-scale prospective study reporting direct-acting antiviral outcomes in sub-Saharan Africa. The high adherence and treatment success without intensive support measures or highly specialised clinical providers, and lack of treatment discontinuations due to adverse events support the feasibility of HCV treatment decentralisation and scale-up in sub-Saharan Africa. Genotype 4r is uniquely expressed in this region and associated with high rates of treatment failure, suggesting a need for rigorous test-of-cure in clinical practice and consideration of the use of newer pangenotypic direct-acting antiviral regimens in this region.

Treatment of hepatitis C virus (HCV) infection for patients with human immunodeficiency virus (HIV) has improved with direct acting antivirals. However, outcomes among Black persons treated with ledipasvir/sofosbuvir (LDV/SOF) may be inferior to non-Blacks. We assessed responses to LDV/SOF in a cohort of Black HIV/HCV coinfected persons.Retrospective chart reviews were conducted for Black, genotype 1 (GT1), HIV/HCV coinfected patients treated with LDV/SOF at 3 hospitals in Newark, NJ between Jan. 2014 and July 2016. Data collected included demographics, HCV treatment history, treatment duration, and response.One hundred seventeen HIV/HCV coinfected Black patients started treatment with LDV/SOF but 5 had no follow-up data and 5 prematurely discontinued treatment (1 due to side effects). We included 107HIV/HCV coinfected patients who completed LDV/SOF at all 3 sites. The study population was 65% male, median age 58 years, 26% had cirrhosis, and 78% had GT1a. Thirty-one percent were treatment experienced but none with prior NS5a treatment. At baseline, median CD4 count was 680cells/mm, HIV viral load (VL) was <40copies/mL in 94% and median HCV VL was 2,257,403IU/mL. Twenty-nine percent of patients changed antiretroviral treatment before LDV/SOF treatment due to drug interactions. Six, 89, and 12 patients completed 8, 12, and 24 wk of LDV/SOF, resp. Overall sustained virol. response rate was 93% with 7 relapses.In this real-world cohort of Black, GT1, HIV/HCV coinfected patients, LDV/SOF had high sustained virol. response 12 wk post completion of treatment rate of 93%. This data supports the overall high efficacy of LDV/SOF in a historically difficult-to-treat patient population.

Nucleotides play a role in inflammation processes: cAMP and cGMP in the endothelial barrier function, ADP in platelet aggregation, ATP and UTP in vasodilatation and/or vasoconstriction of blood vessels, UDP in macrophages activation. The aim of this study is to develop and validate a LC/MS-MS method able to quantify simultaneously nine nucleotides (AMP, cAMP, ADP, ATP, GMP, cGMP, UMP, UDP and UTP) in biol. matrixes (cells and plasma). The method we developed, has lower LOQ’s than others and has the main advantage to quantify all nucleotides within one single injection in less than 10 min. The measured nucleotides concentrations obtained with this method are similar to those obtained with assay kits com. available. Anal. of plasma and red blood cells from healthy donors permits to estimate the physiol. concentration of those nucleotides in human plasma and red blood cells, such information being poorly available in the literature. Furthermore, the protocol presented in this paper allowed us to observe that AMP, ADP, ATP concentrations are modified in human red blood cells and plasma after a venous stasis of 4 min compared to physiol. blood circulation. Therefore, this specific method enables future studies on nucleotides implications in chronic inflammatory diseases but also in other pathologies where nucleotides are implicated in.

Abstract: Nsp15, a uridine specific endoribonuclease conserved across coronaviruses, processes viral RNA to evade detection by host defense systems. Crystal structures of Nsp15 from different coronaviruses have shown a common hexameric assembly, yet how the enzyme recognizes and processes RNA remains poorly understood. Here we report a series of cryo-EM reconstructions of SARS-CoV-2 Nsp15, in both apo and UTP-bound states. The cryo-EM reconstructions, combined with biochem., mass spectrometry, and mol. dynamics, expose mol. details of how critical active site residues recognize uridine and facilitate catalysis of the phosphodiester bond. Mass spectrometry revealed the accumulation of cyclic phosphate cleavage products, while anal. of the apo and UTP-bound datasets revealed conformational dynamics not observed by crystal structures that are likely important to facilitate substrate recognition and regulate nuclease activity. Collectively, these findings advance understanding of how Nsp15 processes viral RNA and provide a structural framework for the development of new therapeutics.

BACKGROUND: Licensure of ledipasvir/sofosbuvir for chronic hepatitis C virus (HCV) infection in adolescents was based on clinical trials on patients mainly with genotype 1. We aimed to evaluate the effectiveness and short-term safety of this newly approved antiviral in adolescents with HCV genotype 4. METHODS: This was a study of 51 HCV-infected adolescents, who received the adult dose of ledipasvir/sofosbuvir, once daily for 12 weeks, and were followed-up for 12 weeks post-treatment. Laboratory tests, quantitation of HCV RNA, HCV genotyping, IL-28rs gene polymorphism and transient elastography were performed at baseline. Follow-up visits were done for blood testing and adverse events recording. RESULTS: The mean age was 14.7 ± 1.5 years (11-17.5), with a male to female ratio of 1.7:1. All patients were genotype 4a, and 76.5% had the CC IL-28 gene polymorphism. About 50% gave a history of HCV-infected mother, and 31% were treatment-experienced. Liver stiffness was F0 in 72.5%, F0-F1 in 13.7% and F1-F2 in 13.7%. Adverse events were mainly abdominal pain in 72.5%, headache in 64.7% and diarrhea in 53% of patients; these were mild. A reversible increase in creatinine level with a concomitant decline in estimated glomerular filtration rate was observed in the first month of treatment. By the end of week 12, a significant decline in liver enzymes was observed. All patients achieved an early, end of treatment, and a sustained virologic response. CONCLUSIONS: Adolescent patients with genotype 4 chronic HCV infection achieved a good response rate with good ontreatment tolerability for ledipasvir/sofosbuvir therapy.

Chlamydia trachomatis is a sexually transmitted pathogen and a global public health concern. Little is known about the microbial composition and function across endocervical, vaginal, and rectal microbiomes in the context of C. trachomatis infection. We evaluated the microbiomes of 10 age-matched high-risk Fijian women with and without C. trachomatis using metagenomic shotgun sequencing (MSS). Lactobacillus iners and Lactobacillus crispatus dominated the vagina and endocervix of uninfected women. Species often found in higher relative abundance in bacterial vaginosis (BV) – Mageeibacillus indolicus, Prevotella spp., Sneathia spp., Gardnerella vaginalis, and Veillonellaceae spp. – were dominant in C. trachomatis-infected women. This combination of BV pathogens was unique to Pacific Islanders compared to previously studied groups. The C. trachomatis-infected endocervix had a higher diversity of microbiota and microbial profiles that were somewhat different from those of the vagina. However, community state type III (CST-III) and CST-IV predominated, reflecting pathogenic microbiota regardless of C. trachomatis infection status. Rectal microbiomes were dominated by Prevotella and Bacteroides, although four women had unique microbiomes with Gardnerella, Akkermansia, Bifidobacterium, and Brachyspira. A high level of microbial similarity across microbiomes in two C. trachomatis-infected women suggested intragenitorectal transmission. A number of metabolic pathways in the endocervix, driven by BV pathogens and C. trachomatis to meet nutritional requirements for survival/growth, 5-fold higher than that in the vagina indicated that endocervical microbial functions are likely more diverse and complex than those in the vagina. Our novel findings provide the impetus for larger prospective studies to interrogate microbial/microbiome interactions that promote C. trachomatis infection and better define the unique genitorectal microbiomes of Pacific Islanders.

BACKGROUND: Highly effective direct-acting antiviral drugs provide the opportunity to eliminate hepatitis C virus (HCV) infection, but established pathways can be ineffective. We aimed to examine whether a community pharmacy care pathway increased treatment uptake, treatment completion, and cure rates for people receiving opioid substitution therapy, compared with conventional care. METHODS: This cluster-randomised trial was done in Scottish community pharmacies. Before participants were recruited, pharmacies were randomly assigned (1:1) to refer patients with evidence of HCV antibodies to conventional care or offered them care in the pharmacy (pharmacist-led care). Pharmacies were stratified by location. All pharmacies were trained to offer dried blood spot testing. All eligible participants had received opioid substitution therapy for approximately 3 months, and those eligible to receive treatment in the pharmacist-led care pathway were HCV PCR positive, were infected with HCV genotype 1 or 3, and were willing to have a pharmacist supervise their antiviral drug administration. Neither pharmacists nor patients were masked to treatment allocation. In both groups, assessment blood samples were taken, infection with HCV was confirmed, and daily oral ledipasvir-sofosbuvir (90 mg ledipasivir plus 400 mg sofosbuvir) for 8 weeks for genotype 1 or daily oral sofosbuvir (400 mg) plus oral daclatasvir (60 mg) for 12 weeks for genotype 3 was prescribed by a nurse (conventional care group) or pharmacist (pharmacist-led care group). In the conventional care group, the patient received care at a treatment centre. Once prescribed, medication in both groups was delivered as daily modified directly observed therapy alongside opioid substitution therapy in the participants’ pharmacy where treatment was observed on 6 days per week. The primary outcome was the number of patients with sustained virological response 12 weeks after completion of treatment (SVR12) as a proportion of the number of people receiving opioid substitution therapy at participating pharmacies. Participants were monitored at each visit for nausea and fatigue; other adverse events were recorded as free text. Secondary outcomes compared key points on treatment pathway between the two groups. These key points were the proportion of patients having dry blood spot testing, the proportion of patients initiating HCV treatment, the proportion of patients completing the 8 or 12 week HCV course of treatment, and the proportion of patients with sustained virological response at 12 months. This study is registered with ClinicalTrials.gov, NCT02706223. FINDINGS: 56 pharmacies were randomly assigned (28 to each group; one pharmacy withdrew from the conventional care group). The 55 participating pharmacies included 2718 patients receiving opioid substitution therapy (1365 in the pharmacist-led care group and 1353 in the conventional care group). More patients met the primary endpoint of SVR12 in the pharmacist-led care group (98 [7%] of 1365) than in the conventional care group (43 [3%] of 1353; odds ratio 2·375, 95% CI 1·555-3·628, p<0·0001). More users of opioid substitution therapy in the pharmacist-led care group versus the conventional care group agreed to dry blood spot testing (245 [18%] of 1365 vs 145 [11%] of 1353, 2·292, 0·968-5·427, p=0·059); initiated treatment (112 [8%] of 1365 vs 61 [4%] of 1353, 1·889, 1·276-2·789, p=0·0015) and completed treatment (108 [8%] of 1365 vs 58 [4%] of 1353, 1·928, 1·321-2·813, p=0·0007). The data for sustained virological response at 12 months are not reported in this study: patients remain in follow-up for this outcome. No serious adverse events were recorded. INTERPRETATION: Using pharmacists to deliver an HCV care pathway made testing and treatment more accessible for patients, improved engagement, and maintained high treatment success rates. The use of this pathway could be a key part of an integrated and effective approach to HCV elimination at a community level.
