Partial Recovery of Telomere Length After Long-term Virologic Suppression in Persons With HIV-1.

Background: People with HIV-1 (PWH) age differently than the general population. Blood telomere length (BTL) attrition is a surrogate biomarker of immunosenescence and aging in PWH. BTL is reduced immediately after HIV-1 infection and recovers in PWH with long-term virologic suppression, but the extent of this recovery is unknown.

A Comparison of the Efficacy of Treatment With Fidaxomicin Versus Vancomycin in Clostridioides difficile Infection.

Background infection (CDI) is a major cause of diarrhea in hospitalized adult patients. This study aims to evaluate the clinical characteristics, clinical cure, recurrence and mortality in patients with CDI treated with either fidaxomicin or vancomycin. Methods A retrospective case-control study was conducted on patients with CDI treated with either fidaxomicin or vancomycin at a hospital from January 2019 to March 2022.

Human intestinal spirochetosis: an entity associated with sexual transmitted infections.

Introduction: Human intestinal spirochetosis (HIE) is a poorly studied clinical entity with variable clinical manifestations. However, in recent years it has gained special relevance because an increasing number of cases have been described in people living with HIV (PWH) and in patients with a history of sexually transmitted infections (STI) or immunosuppression.

Methods: Retrospective review of all HIE cases identified in a tertiary level hospital (Hospital Universitario la Paz, Madrid) between 2014 and 2021.

Controversies in the Design of Strategies for the Cure of HIV Infection.

The cure for chronic human immunodeficiency virus (HIV) infections has been a goal pursued since the antiretroviral therapy that improved the clinical conditions of patients became available. However, the exclusive use of these drugs is not enough to achieve a cure, since the viral load rebounds when the treatment is discontinued, leading to disease progression. There are several theories and hypotheses about the biological foundations that prevent a cure.

Clinical Cure of a Difficult-to-Treat Resistant Ventriculitis Using Cefiderocol: A Case Report and Literature Review.

Ventriculitis is a complication of meningitis (community-acquired or nosocomial) or other central nervous system (CNS) infections such as brain abscess. They are associated with a different spectrum of microorganisms, from resistant gram-negative bacilli to staphylococci, that can lead serious illness with high mortality. Difficult-to-treat resistance (DTR) gram-negative bacilli may increase to 20% of deaths respective to susceptible isolates of the same bacteria.

Impact of preexisting nucleos(t)ide reverse transcriptase inhibitor resistance on the effectiveness of bictegravir/emtricitabine/tenofovir alafenamide in treatment experience patients.

Introduction: Few clinical trials and cohort studies have evaluated the efficacy of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV (PWH) with preexisting M184V/I or other nucleos(t)ide reverse transcriptase inhibitor (NRTI) resistance-associated mutations (RAMs). Real-world data are also scarce.

Methods: Retrospective review of treatment-experienced patients who started B/F/TAF in a cohort of PWH.
