Abnormal liver chemistry constitutes an independent prognostic factor of less favorable clinical course in patients with COVID-19.

Introduction: abnormal liver biochemistry (ALB) is correlated with increased clinical involvement or severity in COVID-19, but its prognostic implications have not been studied extensively. The aim of this study was to determine whether ALB is a risk factor for unfavorable clinical outcome and involvement.

Materials And Methods: a retrospective, single-center study in confirmed COVID-19 cases.

The potential role of 13-valent pneumococcal conjugate vaccine in preventing respiratory complications in bacteraemic pneumococcal community-acquired pneumonia.

Introduction: Pneumococcal 13-valent vaccine (PCV-13) has a potential role in preventing bacteraemic pneumococcal pneumonia and its complications, but little is known about its ability to specifically prevent respiratory complications. Our aim were to analyse the pneumococcal serotypes associated with the development of respiratory complications and the potential role of PCV-13 in preventing respiratory complications in bacteraemic pneumococcal pneumonia.

Material And Methods: We analysed demographic characteristics, comorbidities, antibiotic resistances and the outcomes of a cohort of 65 vaccine-naïve bacteraemic pneumococcal pneumonias, stratified by the pneumococcal serotypes included in PCV13 vs.

Recommendations for vaccination against pneumococcus in kidney patients in Spain.

Unlabelled: Invasive pneumococcal disease (IPD) is a serious problem in some risk groups: patients with stage 4 and 5 chronic kidney disease, stage 3 CKD undergoing immunosuppressive treatment, nephrotic syndrome or diabetes. These individuals are more susceptible to infections and more prone to suffering more severe and worsening symptoms. Vaccination is one of the strategies for preventing IPD, although vaccination coverage in this group at present is lower than desired.

Mediastinal fibrosis and superior vena cava syndrome.

Superior vena cava syndrome is a clear sign for clinicians of infiltrative mediastinal involvement, usually caused by neoplasms in this location, and it is an indicator of poor prognosis. However, other diseases of benign origin can also cause these alterations. We present the case of a 34-year-old patient who debuted with symptoms of superior vena cava syndrome due to idiopathic mediastinal fibrosis, which presented a torpid evolution and few therapeutic alternatives.

Microbiology and risk factors for community-acquired pneumonia.

The outcome of community-acquired pneumonia (CAP) depends on the interaction between the infectious agent and the host response. Nowadays the etiology of CAP can be established in ~60% of the cases, and Streptococcus pneumoniae remains the main etiological agent in outpatients, those hospitalized, or those requiring intensive care unit (ICU) admission. Recently, the development of nucleic acid amplification techniques has emphasized the role of viruses as important etiological agents in CAP.

[New challenges in community-acquired pneumonia].

Community-acquired pneumonia is a major cause of morbidity and mortality. Severity assessment is a fundamental tool in the management of pneumonia that allows patients to be stratified according to risk of death and the most appropriate treatment intensity to be provided. The most widely used scales are the PSI/Fine and CURB-65 scales, which have been widely validated and are easy to calculate in clinical practice.

[Pneumococcal pneumonia in hospitalized patients. Therapeutic implications of resistances to penicillin and erythromycin].

Background And Objective: Streptococcus pneumoniae is the main etiological agent of community-acquired pneumonia. The aim of this work was to ascertain the resistance profiles of pneumococcus to penicillin and erythromycin and to analyse whether such profiles lead to different disease developments.

Patients And Method: A retrospective analysis was carried out in 75 cases of pneumococcal pneumonia corresponding to hospitalized patients.
