Clarithromycin for improved clinical outcomes in community-acquired pneumonia: A subgroup analysis of the ACCESS trial.

Background: In the ACCESS trial, the addition of clarithromycin to standard-of-care antibiotics (SoC) enhanced early clinical response and attenuated the inflammatory burden in adults with community-acquired pneumonia (CAP) requiring hospitalisation. A post-hoc analysis was performed to investigate the benefit in specific subgroups.

Methods: The primary endpoint comprised two conditions to be met during the first 72 h: ≥50% decrease in respiratory symptom severity score; and any of ≥30% decrease in sequential organ failure assessment score and favourable change in the kinetics of procalcitonin (PCT, defined as ≥80% PCT decrease or PCT <0.

TLR4 and TNF-α single nucleotide polymorphisms in patients with brucellosis: Association with infection complications.

Objectives: To investigate associations of the carriage of single nucleotide polymorphisms (SNPs) of proteins involved in the immune response of patients with brucellosis.

Methods: A case control study of patients with brucellosis upon WHO criteria. Blood genomic analysis was performed by RFLP- PCR for the detection of SNPs: i) at promoters -376 G > A (rs1800750); -308 G > A (rs 1,800,629); -238 G > A (rs361525) of the TNF gene, ii) at -896 A > G Asp299Gly (rs4986790) and -1196 C > T Thr399Ile (rs4986791) positions of the TLR-4 gene.

Investigating the Role of Anti-TPO Antibodies in HIV-Associated Thrombocytopenia before and after Initiation of HAART: A Case-Control Longitudinal Study.

This longitudinal, case-control study aimed to investigate the role of thrombopoietin (TPO) and anti-TPO antibodies in HIV-associated thrombocytopenia, focusing on the changes seen before and after the initiation of highly active antiretroviral therapy (HAART). Patients were assessed before and at least six months after the initiation of HAART. In total, 75 PLWHIV (age/sex-matched and randomized at 2:1, according to thrombocytopenia status) were included in this study.

Calprotectin serum levels on admission and during follow-up predict severity and outcome of patients with COVID-19: A prospective study.

Background & Aims: Calprotectin reflects neutrophil activation and is increased in various inflammatory conditions including severe COVID-19. However, serial serum calprotectin measurements in COVID-19 patients are limited. We assessed prospectively, calprotectin levels as biomarker of severity/outcome of the disease and a COVID-19 monitoring parameter in a large cohort of consecutive COVID-19 patients.
