ABSTRACT
Current medical guidelines consider pregnant women with COVID-19 to be a high-risk group. Since physiological gestation downregulates the immunological response to maintain "maternal-fetal tolerance", SARS-CoV-2 infection may constitute a potentially threatening condition to both the mother and the fetus. To establish the immune profile in pregnant COVID-19+ patients, a cross-sectional study was conducted. Pregnant women with COVID-19 (P-COVID-19+; n = 15) were analyzed and compared with nonpregnant women with COVID-19 (NP-COVID-19+; n = 15) or those with physiological pregnancy (P-COVID-19-; n = 13). Serological cytokine and chemokine concentrations, leucocyte immunophenotypes, and mononuclear leucocyte responses to polyclonal stimuli were analyzed in all groups. Higher concentrations of serological TNF-α, IL-6, MIP1b and IL-4 were observed within the P-COVID-19+ group, while cytokines and chemokines secreted by peripheral leucocytes in response to LPS, IL-6 or PMA-ionomicin were similar among the groups. Immunophenotype analysis showed a lower percentage of HLA-DR+ monocytes in P-COVID-19+ than in P-COVID-19- and a higher percentage of CD39+ monocytes in P-COVID-19+ than in NP-COVID-19+. After whole blood polyclonal stimulation, similar percentages of T cells and TNF+ monocytes between groups were observed. Our results suggest that P-COVID-19+ elicits a strong inflammatory response similar to NP-COVID19+ but also displays an anti-inflammatory response that controls the ATP/adenosine balance and prevents hyperinflammatory damage in COVID-19.

The authors present the case of a twenty-one-year-old woman with familial Mediterranean fever who during her first pregnancy developed a primary antiphospholipid syndrome. This is an association not reported previously.

UNLABELLED: The scope of this work is to analyze the usefulness and indications of preoperative evaluation. PATIENTS AND METHODS: 791 consecutive patients candidate for surgical treatment, were studied prospectively under the next inclusion criteria: 40 years old or less than 40 years old. Blood count cell, glucose, urea, creatinine, sodium, potassium, prothrombin time, partial thromboplastin time, platelets count, liver function tests, chest x-ray and electrocardiograph made before entry. In the the post liver, lung, bleeding, infectious or metabolic complications was done, while visiting the patients every day until discharge. Relative risk (RR) was calculated for every variable, analyzing differences with X2 and Fisher's Test. Those variables with statistical significance value were analyzed with logistic regression. Only 751 patients were studied, there were 335 male (44%) and 416 female (56%), with mean age of 63.9 years. Metabolic disorders (16.9%) and postoperative infections (7.0%) were the more frequent complications. Hemorrhage during of after surgery occurred in 2.2% of the patients. There were seventeen deaths (2.2%) related directly with surgery, with systemic illness or with postoperative complications. Selection of auxiliary tests for preoperative evaluation must be agree with clinical evaluation. The major objective of clinical evaluation is to estimate risk factors for surgery.
