Objective: In the context of the advancement of antiretroviral therapy and, as the characteristics of people living with HIV progress toward an aging population, understanding the causes of treatment interruption becomes crucial. The aim of the study was to determine the change in reasons for antiretroviral treatment discontinuation for 12 years. Secondarily, compare annual antiretroviral regimen discontinuation rate and factors associated.

Background And Objectives: Acute kidney injury (AKI) is common among hospitalized patients with COVID-19 and associated with worse prognosis. The Spanish Society of Nephrology created the AKI-COVID Registry to characterize the population admitted for COVID-19 that developed AKI in Spanish hospitals. The need of renal replacement therapy (RRT) therapeutic modalities, and mortality in these patients were assessed.

(), an important pathogen in immuno-compromised patients, has recently gained attention in patients admitted in intensive care units (ICU). We sought to investigate clinical features of infections caused by in ICU patients and identify risk factors for mortality. We conducted a retrospective study in two multivalent non-COVID-19 ICUs of tertiary-teaching hospitals in Greece and Spain, including patients with isolated from at least one clinical specimen along with clinical signs of infection.

Introduction: Hypogammaglobulinemia after front-line immunochemotherapy for follicular lymphoma is a poorly studied adverse event that could be related to the appearance of severe and/or recurrent non-neutropenic infections which could affect the quality of life of the patients, even motivating a need of long-term replacement therapy with human immunoglobulins.

Methods: Observational, retrospective study aiming to estimate the incidence of hypogammaglobulinemia, as well as its severity and clinical consequences, and to explore possible predictive factors for its development. Specific immunoglobulin deficiencies were also studied.

Background: There is a high prevalence of multimorbidity and polypharmacy among older people, especially in people living with HIV (PLWH) with an increased life expectancy due to effective antiretroviral therapy (ART). Consequently, there is a higher risk of potentially inappropriate medications (PIM), potential drug-drug interactions (DI), and problems of non-adherence to treatment (NAC) in older PLWH. PIMDINAC criteria (potentially inappropriate medications (PIM), drug-drug interactions (DI), and non-adherence to treatment (NAC)) purport to jointly analyse these problems.

Introduction: The high pharmacotherapeutic complexity, drug interactions and lack of adherence to concomitant medication are circumstances with negative consequences in the clinical evolution of patients with HIV infection. The 3-HIT phenomenon refers to the simultaneous occurrence of these situations. The objective of the study is to determine the prevalence of the phenomenon 3-HIT in the polymedicated HIV population as well as to determine factors related to its occurrence.

Introduction: Aging of people living with HIV could be related to potentially inappropiate medication prescriptions, drugs interactions and lack of drugs adherence. PIMDINAC criteria seek to jointly analyze these problems. The objective of this study is to determine the prevalence of PIMDINAC criteria in an elderly HIV population.

Background: Eribulin's clinical benefit remains unclear; so, studies analyzing its effectiveness in routine clinical practice are interesting.

Patients And Methods: This is a multicenter, retrospective study including patients with human epidermal growth factor receptor-2-negative metastatic breast cancer which assesses effectiveness and safety of eribulin.

Results: A total of 140 women were included, with a median age of 57 years.

Primary aim was to assess prevalence and severity of potential and real drug-drug interactions (DDIs) among therapies for COVID-19 and concomitant medications in hospitalized patients with confirmed SARS-CoV-2 infection. The secondary aim was to analyze factors associated with rDDIs. An observational single center cohort study conducted at a tertiary hospital in Spain from March 1st to April 30th.

Background: Our objective was to assess the impact on mortality, antibacterial therapy duration, and length of stay of using PCT to guide antibiotic cessation in critically ill patients with sepsis or septic shock.

Research Design And Methods: A systematic literature search was performed in PubMed, Embase, ISI Web of Knowledge, BioMed Central, ScienceDirect and the Cochrane Central Register of Controlled Trials, of clinical trials published in English before December 31, 2019. Eligible studies should be carried out in adults at ICU with sepsis, comparing the PCT-guided antimicrobial therapy with standard of care.

Introduction: In recent decades, HIV has become a chronic disease with which the HIV specialist pharmacist plays a fundamental role. The traditional pharmaceutical care model followed to date relied excessively on the medication, obviating the uniqueness of each patient. The purpose of this study was to determine the influence and acceptance of a Capacity-Motivation-Opportunity (CMO)-based structured pharmaceutical care (PC) intervention in a multidisciplinary team for improving healthcare results.

The impact of drug-drug interactions (DDI) between ritonavir-boosted lopinavir (LPV-r) to treat patients with coronavirus disease 2019 (COVID-19) and commonly used drugs in clinical practice is not well-known. Thus, we evaluated the rate and severity of DDI between LPV-r for COVID-19 treatment and concomitant medications. This was a cross-sectional study including all individuals diagnosed of SARS-CoV-2 infection treated with LPV-r and attended at a single center in Southern Spain (March 1st to April 30th, 2020).

Background: Graft-versus-host disease (GvHD) is the main life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT). Thirty to 80% of GvHD patients do not respond to first-line treatment and a second-line treatment is not universally established. Based on their immunomodulatory properties, mesenchymal stromal cells (MSC) have been proposed for the prevention and the treatment of GvHD in patients undergoing HSCT.

Introduction: Inflammasomes are recognized as key components of the innate immune response in sepsis. We aimed to describe the transcriptional expression of nucleotide-binding domain, leucine-rich repeat-containing receptor, pyrin domain-containing-3 (NLRP3), and serum interleukin-1β (IL-1 β) in critically ill patients, their changes over the first week and their prognostic value in septic patients.

Methods: Prospective study including patients with sepsis based on Sepsis-3 definitions and a control group of critically ill patients without sepsis.

Purpose: Information about immunocompromised patients infected with influenza A (H1N1) virus and requiring admission to the ICU is lacking. Our objective was to know the clinical characteristics of these patients and to identify treatment-related variables associated with mortality.

Material And Methods: A prospective multicenter observational cohort study was based on data from a Spanish registry (2009-2015) collected by 148 Spanish ICUs.

Background: The global crisis of bacterial resistance urges the scientific community to implement intervention programs in healthcare facilities to promote an appropriate use of antibiotics. However, the clinical benefits or the impact on resistance of these interventions has not been definitively proved.

Methods: We designed a quasi-experimental intervention study with an interrupted time-series analysis.

Background: There is a concern to conduct de-escalation in very sick patients.

Aims: To determine if de-escalation is feasible in ICU settings.

Methods: We performed a metaanalysis of published studies conducted comparing de-escalation (defined by withdrawal of at least one antimicrobial empirically prescribed, switch to a new antimicrobial with narrower spectrum and withdrawal of at least one antimicrobial plus change of another drug to a new one with narrower spectrum) in non-immunocompromised patients with sepsis admitted to ICU.

Objective: The time to positivity (TTP) of blood cultures in patients with bloodstream infections (BSIs) has been considered to be a possible prognostic tool for some bacterial species. However, notable differences have been found between sampling designs and statistical methods in published studies to date, which makes it difficult to compare results or to derive reliable conclusions. Our objective was to evaluate the clinical and microbiological implications of TTP among patients with BSI caused by the most common pathogens.
