complex (MAC) infection in severely immunocompromised people living with HIV: Findings from a five-year cohort.

Background: We sought to clarify the current incidence, risk factors and symptoms of disseminated complex (dMAC) infection in admitted people living with HIV in a hospital in the Southeast of Spain.

Methods: 5-years observational, retrospective and single-centre study. Demographic, clinical and analytical variables, along with microbiological, treatment and follow-up were collected.

The HIV-1 reservoir landscape in persistent elite controllers and transient elite controllers.

BACKGROUNDPersistent controllers (PCs) maintain antiretroviral-free HIV-1 control indefinitely over time, while transient controllers (TCs) eventually lose virological control. It is essential to characterize the quality of the HIV reservoir in terms of these phenotypes in order to identify the factors that lead to HIV progression and to open new avenues toward an HIV cure.METHODSThe characterization of HIV-1 reservoir from peripheral blood mononuclear cells was performed using next-generation sequencing techniques, such as full-length individual and matched integration site proviral sequencing (FLIP-Seq; MIP-Seq).

Expanding HIV clinical monitoring: the role of CD4, CD8, and CD4/CD8 ratio in predicting non-AIDS events.

Background: While a low CD4/CD8 ratio during HIV treatment correlates with immunosenescence, its value in identifying patients at an increased risk for clinical events remains unclear.

Methods: We analyzed data from the CoRIS cohort to determine whether CD4 count, CD8 count, and CD4/CD8 ratio at year two of antiretroviral therapy (ART) could predict the risk of serious non-AIDS events (SNAEs) during the next five years. These included major adverse cardiovascular events, non-AIDS-defining malignancies, and non-accidental deaths.

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.

Dalbavancin as suppressive antibiotic therapy in patients with prosthetic infections: efficacy and safety.

Suppressive antibiotic therapy (SAT) is a strategy to alleviate symptoms and/or to reduce the progression of an infection when other treatment options cannot be used. Dalbavancin, due to its prolonged half-life, enables (bi) weekly dosing. Here, we report our multicenter real-life clinical experience with dalbavancin used as SAT in patients with prosthetic joint or vascular infections.

Do specific antimicrobial stewardship interventions have an impact on carbapenem resistance in Gram-negative bacilli? A multicentre quasi-experimental ecological study: time-trend analysis and characterization of carbapenemases.

Background: Carbapenem-resistant Gram-negative bacilli (CR-GNB) are among the most threatening microorganisms worldwide and carbapenem use facilitates their spread. Antimicrobial stewardship programmes (ASPs) can help to optimize the use of antibiotics. This study evaluates the impact of a multifaceted educational ASP on carbapenem use and on the epidemiology of CR-GNB.

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.

Efficacy and safety of replacing lopinavir with atazanavir in HIV-infected patients with undetectable plasma viraemia: final results of the SLOAT trial.

Background: Atazanavir seems to be a protease inhibitor (PI) with a more favourable metabolic profile. Information regarding the potential benefit of replacing lopinavir/ritonavir by atazanavir in HIV-infected patients with prolonged viral suppression is scarce. If proved, this strategy could be particularly attractive for the subset of patients with greater cardiovascular risk.

Outbreak of syphilis, but not of acute hepatitis C, among HIV-infected homosexual men in Madrid.

Background: Clustered cases of acute hepatitis C virus (HCV) infection, frequently accompanied by sexually transmitted diseases, have recently been reported among men who have sex with men (MSM) in several European cities.

Method: We performed a retrospective record of cases of syphilis in a large cohort of HIV-infected individuals on regular follow-up in Madrid, Spain. HCV testing was carried out in all of them.

Telbivudine: a new option for the treatment of chronic hepatitis B.

Chronic hepatitis B virus (HBV) infection affects > 350 million individuals worldwide. Chronic hepatitis B is associated with complications of end-stage liver disease, including cirrhosis and hepatocellular carcinoma. HBV replication is the best predictor of liver disease progression to cancer, and antiviral therapy may diminish or halt this unfavorable outcome.

Treatment of chronic hepatitis B or C in HIV-infected patients with dual viral hepatitis.

Dual chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are recognized in 3%-5% of human immunodeficiency virus (HIV)-infected individuals. More severe liver disease is seen in these patients. Viral interference may account for the fact that replication of one virus generally predominates over replication of the other.

Sustained virological response following HCV therapy is associated with non-progression of liver fibrosis in HCV/HIV-coinfected patients.

Background: Chronic hepatitis C leads to progressive liver fibrosis, which is accelerated in HIV-coinfected patients. Unfortunately, hepatitis C virus (HCV) therapy provides sustained virological response (SVR) to only 40% of coinfected patients. Little is known about the regression of hepatic fibrosis in treated patients.

[HIV and HCV coinfection].

Chronic hepatitis due to hepatitis C virus (HCV) infection is now one of the leading causes of morbidity and mortality among HIV-infected individuals. Coinfected patients present an accelerated course toward cirrhosis and an enhanced risk of liver toxicity associated with the use of antiretroviral agents. Treatment of chronic hepatitis C in HIV1 patients is less efficacious than in HCV-monoinfected individuals and requires particular expertise.
