Specific antibodies are produced after infection by SARS-CoV2. Currently, the understanding of antibody responses following infection with SARS-CoV-2 is limited including the magnitude, duration of responses and correlates of protective immunity following infection. Here we intended to characterize humoral immune response in a cohort of 55 hospitalized patients for COVID-19 and its relationship with different demographic and clinical parameters. ⋯ In chronic obstructive pulmonary disease patients, the IgM response is increased, while in immunocompromised and interstitial lung disease patients, IgM and IgG were lower, respectively. Those patients who required critical care, mechanical ventilation and those who died did not present significant differences in the magnitude of humoral response compared to those who had a less severe course. The methodology used adequately reflects the kinetics of antibodies.

Endothelial-specific molecule 1 (endocan) has emerged as an inflammatory biomarker in recent years. The purpose of this study was to investigate the diagnostic value of serum endocan levels in the prediction of COVID-19 disease among patients with a false-negative reverse transcription polymerase change reaction (RT-PCR) test, and also to determine its correlation with the clinical severity of the disease. ⋯ There is a need for different laboratory markers capable of assisting diagnosis and showing COVID-19 infection in suspected COVID-19 RT-PCR false-negative patients. Endocan levels can be used as an assistant blood test for identifying COVID-19 patients with false-negative RT-PCR tests and in determining the clinical severity of the disease.

SARS-CoV-2 infection has, in most cases, a mild course, although acute respiratory distress syndrome is associated with higher mortality. ⋯ Mortality was higher in the public sector, and this could be due to the overcrowding of services, which determined a scarcity of resources.

The SARS-CoV-2 coronavirus pandemic continues causing significant global morbidity and mortality. COVID-19 is an acute respiratory infection that can affect other organs. Tuberculosis (TB) is also an endemic infection that typically occurs with pulmonary involvement and very infrequently, with extra-pulmonary involvement. ⋯ The most frequently associated infection was due to human immunodeficiency virus, (n = 3), underweight (n = 2), COPD (n = 1) and drug addiction (n = 1). Three presented exclusive extrapulmonary involvement of the central nervous system, two pulmonary and pericardial. Four patients (80%) had a favorable evolution.
