No significant difference was found between the intraocular pressure (IOP) lowering of omidenepag isopropyl 0.002% once daily (QD) and twice daily (BID). However, adverse events (AEs) were higher in the BID arm; thus, QD dosing is the preferred dosing frequency for further investigation.

This phase 2, randomized, double-masked, parallel-arm, multicenter study (NCT03858894) was conducted in the United States to examine whether the efficacy and safety of omidenepag isopropyl 0.002% BID dosing was superior to QD dosing in subjects with primary open-angle glaucoma or ocular hypertension.

Randomized subjects (11) received omidenepag isopropyl 0.002% QD (n=50) or BID (n=48) for 6 weeks (after a ≤4-week washout period). IOP was measured at 800 am, 1200 pm, and 400 pm at baseline and weeks 2 and 6. click here The primary efficacy endpoint was IOP at each timepoint at weeks 2 and 6. AEs were evaluated.

Baseline mean diurnal IOP (±SD) post washout was 25.4±2.9 mm Hg (BID) and 24.6±1.9 mm Hg (QD). At weeks 2 and 6, clinically significant IOP reductions from baseline were observed for omidenepag isopropyl BID and QD treatments. Least-squares mean (±SE) IOP differences (BID versus QD) were not statistically significant (week 2 0.44±0.68 to 1.08±0.65 mm Hg; week 6 0.36±0.63 to 0.68±0.68 mm Hg) at any timepoint (all P > 0.05). AEs were 3-fold greater in the BID arm (41.7%; QD 14.0%); the most frequently reported AE was conjunctival/ocular hyperemia (BID 22.9%; QD 2.0%). Five subjects discontinued omidenepag isopropyl prematurely, 4 of 5 owing to AEs (BID 4; QD 0).

In this study, the benefit-risk profile of omidenepag isopropyl 0.002% QD was more favorable than the benefit-risk profile of BID. This difference was driven by a higher incidence of local tolerability issues in the BID arm.

XEN implant was associated with low endothelial cell density (ECD) reduction. In fact, when combined with phacoemulsification, the reduction in ECD was similar to that expected after phacoemulsification alone.

The purpose of this study was to assess the impact of XEN implant, either alone or in combination with phacoemulsification, on ECD.

Multicenter, prospective, observational study conducted on consecutive open-angle glaucoma patients, who were enrolled in the Italian XEN Glaucoma Treatment Registry and have complete endothelial cell count data at baseline and at 6 months after implantation. The primary endpoint was the mean percentage change in ECD between baseline and month 6.

The study included 108 open-angle glaucoma eyes (68 in the XEN-solo and 40 eyes in the XEN+phaco groups) and 60 control eyes (phaco-solo group). As compared with baseline, mean (95% confidence interval, CI) ECD reduction was -5.6% (-7.0% to -4.9%), -11.3% (-13.8% to -10.9%), and -13.0% (14.8% to -11.8%) in the XEN-solo, XEN+phaco, and phaco-solo groups, respectively (P=0.0004, <0.0001, and <0.0001, respectively). As compared with the XEN-solo group, the ECD reduction was significantly greater in the XEN+phaco group (mean difference=5.7%; 95% CI 4.1%-7.3%, P<0.0001) and in the phaco-solo group (mean difference=7.4%; 95% CI 5.7%-9.1%, P<0.0001). ECD reduction was similar in XEN+phaco and phaco-solo groups (P=0.9). In absolute terms, ECD reduction was significantly greater in the XEN+phaco (mean difference=169±306, P=0.021) and in the phaco-solo (mean difference=192±302, P=0.0022) groups than in the XEN-solo group.

The mean ECD reduction 6 months after XEN implantation was low. The ECD reduction in the XEN+phaco group was larger than in the XEN-solo group but was similar to that observed in the phaco-solo group.

The lack of available biomarkers for diagnosing and predicting different stages of liver disease with a noninvasive strategy is currently one of the main challenges that clinicians are facing. Recent evidence indicates that the plasma levels of specific microRNAs (miRNAs) may be significantly altered in patients with liver injury, including those with HIV type 1 (HIV-1) infections.

Large-scale deep sequencing analysis of small RNA expression was performed on plasma samples from 46 patients with HIV-1/hepatitis C virus (HCV) coinfections that did not exhibit liver fibrosis at the time of sampling.

A total of 1065 different miRNAs were identified. After a mean of 10.3 years, 26 out of the 46 patients developed liver fibrosis (stage F2-4) and 20 remained without signs of liver fibrosis (stage F0-1). We identified a signature of seven miRNAs 100-5p, 192-5p, 99a-5p, 122-5p, 125b-2-3p, 1246 and 194-5p, which were highly correlated with progression to liver fibrosis. These seven miRNAs detected liver fibrosis progression with an area under the curve (AUC) of 0.910-0.806. Two miRNAs, 100-5p and 192-5p, which displayed the best AUC values, yielded a sensitivity of 88% and a specificity of 85% for detecting liver fibrosis progression.

Our results demonstrated that circulating miRNA levels had potential in predicting liver fibrosis progression before the clinical detection of liver fibrosis or significant clinical signs, such as elevated liver transaminases or platelets. Thus, our results might facilitate predictions of liver injury progression in patients with HIV-1-infections.

To evaluate the prevalence of low vitamin D levels among well treated pregnant women living with HIV (WLWH) on combination antiretroviral therapy in Denmark, to identify risk factors of low vitamin D levels, and to assess the association between vitamin D status and birth outcomes.

Nationwide cohort study.

All WLWH in Denmark giving birth from 2000 to 2018 with a vitamin D measurement during pregnancy were identified. Risk factors for low vitamin D (deficiency or insufficiency) were assessed using log-binomial regression models, both univariate and adjusted for maternal and HIV factors. The association between vitamin D status and birth outcomes was assessed using linear regression models for continuous outcomes and log-binomial models for binary outcomes.

Among 208 WLWH, the prevalence of vitamin D deficiency was 13%, insufficiency 34%, and sufficiency 53%. Being of African origin (RR 2.68, P = 0.01), Asian origin (RR 3.38, P = < 0.01), or having HIV RNA levels more than 50 copies/ml (RR 1.43, P = 0.04) was associated with an increased risk of low vitamin D level. WLWH with vitamin D deficiency had an increased risk of preterm birth (RR 2.66, P = 0.03) and giving birth to small for gestational age (SGA) children (RR 6.83, P = 0.02) compared with WLWH with sufficient vitamin D level.

Low vitamin D level was prevalent among well treated pregnant WLWH in Denmark, especially among women of African or Asian origin, and women with detectable viral loads. Vitamin D deficiency was associated with an increased risk of preterm birth and SGA.

Abnormal deposition of the antimicrobial peptide amyloid beta (Aβ) is a characteristic of Alzheimer's disease. The objective of this study was to elucidate risk factors for brain Aβ in a cohort enriched for HIV and other neurotropic pathogens.

Cross-sectional cohort study.

We examined autopsy brains of 257 donors with a mean age of 52.8 years; 62% were men; and 194 were HIV+ and 63 HIV-. Hyperphosphorylated tau (p-tau) and Aβ were identified in frontal and temporal regions by immunohistochemistry. APOE genotyping was performed. Clinical and neuropathological predictors for Aβ were identified in univariate analyses, and then tested in multivariate regressions.

Cortical Aβ was identified in 32% of the sample, and active brain infection in 27%. Increased odds of Aβ were seen with increasing age and having an APOE ε4 allele; for the overall sample, HIV+ status was protective and brain infection was not a predictor. Within the HIV+ population, predictors for Aβ were duration of HIV disease and APOE alleles, but not age. When HIV disease duration and other HIV parameters were introduced into models for the entire sample, HIV disease duration was equivalent to age as a predictor of Aβ.

We hypothesize that dual aspects of immune suppression and stimulation in HIV, and beneficial survivor effects in older HIV+ individuals, account for HIV+ status decreasing, and HIV duration increasing, odds of Aβ. Importantly, with HIV, disease duration replaces age as an independent risk for Aβ, suggesting HIV-associated accelerated brain senescence.

The aim of this study was to examine the impact of late presentation (CD4+ cell count <350 cells/μl or an AIDS-defining event) on effectiveness and safety of initial antiretroviral therapy (ART) and to evaluate whether treatment response depends on first-line ART regimen in late presenters.

ART-naive adults from the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) starting triple ART between 2010 and 2018.

We used multivariable models to assess differences in viral suppression (viral load <50 copies/ml), immunological response (change in CD4+ cell count, CD4% (>29%) and CD4/CD8 normalization (>0.4 and >1) multiple T-cell marker recovery (MTMR) CD4+ cell count more than 500 cells/μl and CD4% >29% and CD4/CD8 >1), and treatment discontinuation due to adverse events (TDAE) at 48 weeks from ART initiation.

Out of 8002 participants, 48.7% were late presenters. Of them, 45.8% initiated ART with a NNRTI- (mostly TDF/FTC/EFV), 33.9% with a protease inhibitor (mostly TDF/FTC+boosted experience complete immunological response. In late presenters, effectiveness and safety depends on both the class and the specific first-line ART regimen.
The present study examined interactions between simian immunodeficiency virus (SIV), chronic binge alcohol (CBA), and antiretroviral therapy (ART) on growth factor signaling, neuroinflammatory markers, viral loads (VL), and CD4+ cell counts.

Adult male rhesus macaques were administered CBA (13-14 g ethanol (EtOH)/kg per week) or sucrose (SUC) 3 months prior to SIVmac251 infection until the study endpoint. At viral setpoint, a subset of CBA/SIV+ and SUC/SIV+ macaques were randomized to receive daily ART (9-[2-Phosphonyl-methoxypropyly]adenine [PMPA] 20 mg/kg, 2',3'-dideoxy-5-fluoro-3'-thiacytidine (FTC), 30 mg/kg). Frontal cortex (FC) and basal ganglia (BG) were collected for gene and protein expression.

Relationships between brain and plasma VL or CD4+ cell counts were determined using linear regression. Effects of SIV, CBA, and ART on markers of neuroinflammation and brain-derived neurotrophic factor (BDNF) signaling were determined by ANOVA and linear regression.

SIV increased FC and BG neuroinflammatory and glial cell gene expression (CX3CR1, B2M), and reduced FC protein kinase B phosphorylation.
