Ruminococcus gnavus bacteremia: Literature review and a case report associated with acute flare of ulcerative colitis in an immunocompromised patient.

We present a case of bacteremia caused by Ruminococcus gnavus in an immunocompromised patient. R. gnavus is a Gram-positive strict anaerobe bacterium that forms chains.

Mpox Infection and Sexually Transmitted Infections: A Cross-Sectional Study from a Secondary Hospital in the May-September 2022 International Outbreak.

The aims of this study were to describe the characteristics of patients infected by mpox in our setting, to determine the prevalence of mpox in samples that are classically used for diagnosing sexually transmitted infections (STIs) such as anal, urethral, pharyngeal, and urine, and to assess the prevalence of coinfection with STIs in the same samples. A cross-sectional study was conducted, collecting all confirmed cases of mpox between June and July 2022 using polymerase chain reaction. Sociodemographic data, HIV and other STI status, and prevalence of mpox and STIs in urethral, anal, pharyngeal, or urine samples were collected.

Effectiveness and safety of integrase strand transfer inhibitors in Spain: a prospective real-world study.

Introduction: Second-generation integrase strand transfer inhibitors (INSTIs) are preferred treatment options worldwide, and dolutegravir (DTG) is the treatment of choice in resource-limited settings. Nevertheless, in some resource-limited settings, these drugs are not always available. An analysis of the experience with the use of INSTIs in unselected adults living with HIV may be of help to make therapeutic decisions when second-generation INSTIs are not available.

Lung ultrasound score severity cut-off points in COVID-19 pneumonia. A systematic review and validating cohort.

Objectives: Our purpose was to establish different cut-off points based on the lung ultrasound score (LUS) to classify COVID-19 pneumonia severity.

Methods: Initially, we conducted a systematic review among previously proposed LUS cut-off points. Then, these results were validated by a single-centre prospective cohort study of adult patients with confirmed SARS-CoV-2 infection.

Detailed stratified GWAS analysis for severe COVID-19 in four European populations.

Given the highly variable clinical phenotype of Coronavirus disease 2019 (COVID-19), a deeper analysis of the host genetic contribution to severe COVID-19 is important to improve our understanding of underlying disease mechanisms. Here, we describe an extended genome-wide association meta-analysis of a well-characterized cohort of 3255 COVID-19 patients with respiratory failure and 12 488 population controls from Italy, Spain, Norway and Germany/Austria, including stratified analyses based on age, sex and disease severity, as well as targeted analyses of chromosome Y haplotypes, the human leukocyte antigen region and the SARS-CoV-2 peptidome. By inversion imputation, we traced a reported association at 17q21.

High efficacy of glecaprevir/pibrentasvir for HCV-infected individuals with active drug use.

Objectives: Real world data on glecaprevir/pibrentasvir (G/P) among active drug users are scarce. We evaluated the sustained virological response (SVR) rates of G/P among individuals with and without active drug use in routine clinical practice.

Methods: Two ongoing prospective multicenter cohorts of individuals starting G/P were analyzed.

Identification of IL-6 Signalling Components as Predictors of Severity and Outcome in COVID-19.

IL-6 is one of the major mediators of the hyper-inflammatory responses with complex biological functions as it can signal different modes of action. IL-6 by classical signalling has anti-inflammatory and antibacterial activities, while trans-signalling mediates pro-inflammatory effects. The net biological effect of IL-6 is established by multiple factors beyond its absolute concentration.

HIV/HBV coinfection: temporal trends and patient characteristics, Spain, 2002 to 2018.

BackgroundRecent and reliable estimates on the prevalence of coinfection with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) in Europe are lacking.AimLeveraged on a study designed to assess HIV/HCV coinfection prevalence, we assessed the prevalence of HIV/HBV coinfection in Spain in 2018 and compared the results with five similar studies performed since 2002.MethodsThis cross-sectional prevalence study was carried out in 43 centres, and patients were selected using simple random sampling.

Glucocorticoids alone versus tocilizumab alone or glucocorticoids plus tocilizumab in patients with severe SARS-CoV-2 pneumonia and mild inflammation.

Aim: To assess clinical outcomes according to the immunosuppressive treatment administered to patients with severe SARS-CoV-2 pneumonia and moderate inflammation.

Methods: A retrospective observational cohort study involving 142 patients with severe COVID-19 pneumonia and moderate inflammation divided into three treatment groups (pulses of methylprednisolone alone [groupI], tocilizumab alone [groupII] and methylprednisolone plus tocilizumab [groupIII]). The aim was to assess intergroups differences in the clinical course with a 60-day follow-up and related analytical factors.

Anakinra after treatment with corticosteroids alone or with tocilizumab in patients with severe COVID-19 pneumonia and moderate hyperinflammation. A retrospective cohort study.

Introduction: Little evidence appears to exist for the use of anakinra, a recombinant interleukin-1 receptor antagonist, after non-response to treatment with corticosteroids alone or combined with tocilizumab in patients with severe COVID-19 pneumonia and moderate hyperinflammatory state.

Patients And Methods: A retrospective observational cohort study was carried out involving 143 patients with severe COVID-19 pneumonia and moderate hyperinflammation. They received standard therapy along with pulses of methylprednisolone (group 1) or methylprednisolone plus tocilizumab (group 2), with the possibility of receiving anakinra (group 3) according to protocol.

Effects of Hepatitis C Virus (HCV) Eradication on Bone Mineral Density in Human Immunodeficiency Virus/HCV-Coinfected Patients.

Background: Little is known about the effects of eradication of hepatitis C virus (HCV) on bone mineral density (BMD) and biomarkers of bone remodeling in human immunodeficiency virus (HIV)/HCV-coinfected patients.

Methods: We prospectively assessed standardized BMD (sBMD) at the lumbar spine and femoral neck, World Health Organization BMD categories at both sites, and plasma concentrations of soluble receptor activator of NF-κβ ligand (sRANKL), and osteoprotegerin (OPG) at baseline (the date of initiation of anti-HCV therapy) and at 96 weeks.

Results: A total of 238 patients were included.

Dalbavancin is a novel antimicrobial against Gram-positive pathogens: clinical experience beyond labelled indications.

Very limited labelled indications have been approved for the newer antimicrobials. Data on the clinical uses, efficacy and safety of dalbavancin are scarce, thus here we sought to describe our clinical experience. 16-month observational prospective study was performed.

Hemophagocytic lymphohistiocytosis associated with Leishmania: A hidden passenger in endemic areas.

Introduction: Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and life-threatening syndrome characterized by excessive immune activation. We analyzed the presentation, diagnosis and prognosis of our cohort of HLH-Leishmania cases.

Methods: We studied HLH cases in patients over 14 years of age in the province of Granada (Spain), from January 2008 to November 2019.

Effects of Eradication of HCV on Cardiovascular Risk and Preclinical Atherosclerosis in HIV/HCV-Coinfected Patients.

Background: To assess the effects of eradication of hepatitis C virus (HCV) on cardiovascular risk (CVR) and preclinical atherosclerosis in HIV/HCV-coinfected patients.

Setting: Prospective cohort study.

Methods: We assessed serum lipids, 10-year Framingham CVR scores, pulse wave velocity, carotid intima-media thickness, and biomarkers of inflammation and endothelial dysfunction (BMKs) at baseline and 96 weeks (wk) after initiation of anti-HCV therapy (Rx) in HIV/HCV-coinfected patients.

Prevalence of resistance associated substitutions and efficacy of baseline resistance-guided chronic hepatitis C treatment in Spain from the GEHEP-004 cohort.

Treatment guidelines differ in their recommendation to determine baseline resistance associated substitutions (RAS) before starting a first-line treatment with direct-acting antivirals (DAAs). Here we analyze the efficacy of DAA treatment with baseline RAS information. We conducted a prospective study involving 23 centers collaborating in the GEHEP-004 DAA resistance cohort.
