Abstract Introduction EXO-CD24 are exosomes genetically manipulated to over-express Cluster of Differentiation (CD) 24. It consists of two breakthrough technologies: CD24, the drug, as a novel immunomodulator that is smarter than steroids without any side effects, and exosomes as the ideal natural drug carrier. Methods A randomized, single blind, dose-finding phase IIb trial in hospitalized patients with mild to moderate Coronavirus disease 2019 (COVID-19) related Acute Respiratory Distress Syndrome (ARDS) was carried out in two medical centers in Athens. Patients received either 109 or 1010 exosome particles of EXO-CD24, daily, for five consecutive days and monitored for 28 days. Efficacy was assessed at day 7 among 91 patients who underwent randomization. The outcome was also compared in a post-hoc analysis with an income control group (n = 202) that fit the inclusion and exclusion criteria. Results The mean age was 49.4 (± 13.2) years and 74.4% were male. By day 7, 83.7% showed improved respiratory signs and 64% had better oxygen saturation (SpO2) (p

Serious infections (SIs) remain one of the most significant comorbidities in patients with inflammatory arthritides including psoriatic arthritis (PsA). Apart from methotrexate (MTX) and biologics such as tumor necrosis factor (TNFi), interleukin-12/23 (IL-12/23i), and IL-17 inhibitors (IL-17i), traditionally used for the treatment of PsA, recently biologics such as IL-23i and targeted synthetic agents like JAK inhibitors (JAKi) have been introduced in the daily clinical practice for the treatment of this disease. Although overall the incidence of SIs in patients with PsA treated with these agents is lower compared to patients with rheumatoid arthritis, still a number of unresolved issues regarding their safety remain. Current evidence is reassuring regarding the safety profile of conventional synthetic disease-modifying anti-rheumatic drugs, such as MTX. The increased risk for reactivation of latent infections, such as tuberculosis and hepatitis B virus (HBV) with the use of TNFi, is well described; nevertheless, it is significantly ameliorated with the appropriate screening and prophylaxis. Regarding IL-12/23i and IL-17i, there are no significant safety signals, except from an increased incidence of usually mild Candida infections with the latter class. Newer biologics such as IL-23i and targeted synthetic agents like JAKi have been recently introduced in the daily clinical practice for the treatment of this disease. While IL-23i has not been shown to increase the risk for common or opportunistic infections, a well-established association of JAKi with herpes zoster warrants the attention of rheumatologists. In this narrative review, we summarize the infectious complications of available treatment options by drug class in patients with PsA. [ABSTRACT FROM AUTHOR]

Primary cytomegalovirus infection during pregnancy has a high risk of vertical transmission, with severe fetal sequelae mainly associated with first-trimester infections. We conducted a retrospective analysis of 200 IU/kg cytomegalovirus-specific hyperimmune globulin (HIG), used in first-trimester maternal primary infections for congenital infection prevention. The primary outcome was vertical transmission, defined as neonatal viruria or positive amniocentesis if pregnancy was discontinued. HIG, initially administered monthly and since 2019 biweekly, was discontinued in negative amniocentesis cases. Women declining amniocentesis and positive amniocentesis cases with normal sonography were offered monthly HIG until delivery as a treatment strategy. The total transmission rate was 29.9% (32/107; 10 pregnancy terminations with positive amniocentesis, 18 completed pregnancies with positive amniocentesis and 4 declining amniocentesis). Maternal viremia was the only factor associated with fetal transmission (OR 4.62, 95% CI 1.55–13.74). The transmission rate was not significantly different whether HIG was started during the first or second trimester (28.2% vs. 33.3%; p = 0.58), or between monthly and biweekly subgroups (25.7% vs. 37.8%, p = 0.193). Pre-treatment maternal viremia could inform decisions as a predictor of congenital infection. [ABSTRACT FROM AUTHOR]

Introduction: Currently approved SARS-CoV-2 vaccines have been proven effective in protecting against severe COVID-19; however, they show variable efficacy against symptomatic infection and disease transmission. We studied the breakthrough COVID-19 infection (BTI) after booster vaccination against SARS-CoV-2 in people living with HIV (PWH). Methods: This was a retrospective, single-center, descriptive cohort study involving PWH, who were followed in the HIV Clinic of "Attikon" University Hospital in Athens, Greece. A BTI was defined as a case of laboratory-confirmed COVID-19 occurring at least 14 days after the third (booster) vaccine dose. Results: We studied 733 PWH [males: 89%, mean age: 45.2 ± 11.3 years, mean BMI: 26.1 ± 4.1, HIV stage at diagnosis (CDC classification): A/B/C = 80/9/11%, MSM: 72.6%] with well-controlled HIV infection. At least one comorbidity was recorded in 54% of cases. A history of ≥1 vaccination was reported by 90%, with 75% having been vaccinated with ≥3 vaccines. Four hundred and two (55%) PWH had a history of COVID-19 and 302 (41.2%) had a BTI, with only 15 (3.7%) needing hospitalization. Only one patient was admitted to the ICU, and no death was reported. Regarding BTI after booster dose, increased age (OR = 0.97, 95% CI: 0.96–0.99, per 1-year increase), and COVID-19 infection prior to booster dose (OR = 0.38, 95% CI: 0.21–0.68) were associated with a lower likelihood for BTI, whereas higher BMI (OR = 1.04, 95% CI: 1.01–1.08) and MSM as a mode of HIV transmission were associated with increased risk (OR = 2.59, 95% CI: 1.47–4.56). The incidence rate of total COVID-19 and BTI followed the epidemic curve of the general population, with the highest incidence recorded in June 2022. Conclusions: A significant proportion of PWH with well-controlled HIV infection experienced a BTI, with the majority of them having mild infection. These data, which include the period of Omicron variant predominance, confirm the importance of vaccination in the protection against severe COVID-19. [ABSTRACT FROM AUTHOR]

Objectives There are limited data regarding health-related quality of life (HRQoL) in patients with ANCA-associated vasculitides (AAVs). We aimed to evaluate the HRQoL in patients with AAVs and compare it to another chronic inflammatory disease like RA and to healthy controls (HC). Methods This was a multicentre, cross-sectional study of patients with AAVs and RA recruited from three tertiary rheumatology clinics. HRQoL was assessed with the Short Form 36 Health Survey, which included the physical and mental component summary scores (PCS and MCS). Data from 1007 HC served as historical controls. Results Sixty-six patients with AAVs and 71 with RA were included. Both AAV and RA patients had significantly lower PCS and MCS scores compared with HC (P  < 0.05). HRQoL in AAV patients was worse in patients with microscopic polyangiitis compared with granulomatosis with polyangiitis (physical components) and those with high (VDI ≥ 3) vs low (VDI < 3) damage scores while it did not differ between those with active (BVASv3 ≥ 1) vs. inactive (BVASv3 < 1) disease. In contrast, in RA patients, HRQoL correlated both with disease activity (assessed by the DAS28-ESR) and functional impairment/damage (assessed by the HAQ). Although overall patients with RA had similar HRQoL compared with those with AAVs, those with active RA had worse HRQoL compared with those with active AAV. Conclusions In patients with AAVs, HRQoL correlated more with organ damage and less with disease activity whereas in RA patients, it correlated with both. These data emphasize the need for AAV therapies aiming at preventing organ damage and thus improving HRQoL. [ABSTRACT FROM AUTHOR]

Introduction: In the last decade, substantial differences in the epidemiology of, antiretroviral therapy (ART) for, cascade of care in and support to people with HIV in vulnerable populations have been observed between countries in Western Europe, Central Europe (CE) and Eastern Europe (EE). The aim of this study was to use a survey to explore whether ART availability and therapies have evolved in CE and EE according to European guidelines. Methods: The Euroguidelines in Central and Eastern Europe (ECEE) Network Group conducted two identical multicentre cross‐sectional online surveys in 2019 and 2021 concerning the availability and use of antiretroviral drugs (boosted protease inhibitors [bPIs], integrase inhibitors [INSTIs] and nucleoside reverse transcriptase inhibitors [NRTIs]), the introduction of a rapid ART start strategy and the use of two‐drug regimens (2DRs) for starting or switching ART. We also investigated barriers to the implementation of these strategies in each region. Results: In total, 18 centres participated in the study: four from CE, six from EE and eight from Southeastern Europe (SEE). Between those 2 years, older PIs were less frequently used and darunavir‐based regimens were the main PIs (83%); bictegravir‐based and tenofovir alafenamide‐based regimens were introduced in CE and SEE but not in EE. The COVID‐19 pandemic did not significantly interrupt delivery of ART in most centres. Two‐thirds of centres adopted a rapid ART start strategy, mainly in pregnant women and to improve linkage of care in vulnerable populations. The main obstacle to rapid ART start was that national guidelines in several countries from all three regions did not support such as strategy or required laboratory tests first; an INSTI/NRTI combination was the most commonly prescribed regimen (75%) and was exclusively prescribed in SEE. 2DRs are increasingly used for starting or switching ART (58%), and an INSTI/NRTI was the preferred regimen (75%) in all regions and exclusively prescribed in SEE, whereas the use of bPIs declined. Metabolic disorders and adverse drug reactions were the main reasons for starting a 2DR; in the second survey, HIV RNA <500 000 c/ml and high cluster of differentiation (CD)‐4 count emerged as additional important reasons. Conclusions: In just 2 years and in spite of the emergence of the COVID‐19 pandemic, significant achievements concerning ART availability and strategies have occurred in CE, EE and SEE that facilitate the harmonization of those strategies with the European AIDS Clinical Society guidelines. Few exceptions exist, especially in EE. Continuous effort is needed to overcome various obstacles (administrative, financial, national guideline restrictions) in some countries.

In the era of combination antiretroviral therapy (ART), people living with HIV (PLHIV) still face an increased risk of cardiovascular disease (CVD). Tenofovir alafenamide fumarate (TAF) is superior to its precursor tenofovir disoproxil fumarate (TDF) regarding bone and renal toxicity, but there are concerns about a negative effect on lipid profile. This observational, single-center study investigates the effects on lipid profile and cardiovascular (CVD) risk of the switch from TDF to TAF, in combination with emtricitabine/elvitegravir/cobicistat (FTC/EVG/c), in patients with no exposure to other antiretrovirals. Routine laboratory measurements, somatometric characteristics, and smoking status were analyzed for the assessment of CVD risk changes, using D:A:D and ATP III scores pre- and postswitch. A total of 62 patients with a mean age of 32.9 years were included in this study. Sixty-one patients (98.4%) were men, 38 (61.3%) late presenters, and 39 (62.9%) active smokers. A year after the switch, there was a significant increase in total cholesterol (178 ± 38 to 194 ± 40 mg/dL, p < .001), high-density lipoprotein (45 ± 12 to 48 ± 13 mg/dL, p = .001), and low-density lipoprotein (117 ± 32 to 137 ± 36 mg/dL, p < .001). Mean increase of the 10-year D:A:D score was 1.13% (95% confidence interval, 1.05–1.22, p = .002). Changes were more prominent in nonsmokers. Body mass index and average weight showed an upward trend. Switching from TDF to TAF caused significant changes in lipid profile at 14 months of follow-up, in young, otherwise healthy PLHIV. CVD risk, as measured by D:A:D, showed a statistically significant increase, but more data are needed to determine clinical significance. These results point toward a patient-centered approach when selecting an ART regimen. [ABSTRACT FROM AUTHOR]
