    Introduction / objectives: The cause of c oronavirus disease MESHD2019 (COVID-19) is severe acute r espiratory syndrome MESHD2 (SARS-CoV-2). There are evidences of involvement of immune system in pathogenesis of this disease. We investigated the presence of various vasculitis HP asculitis- MESHDassociated auto- antibodies SERO and complement levels in a series of patients with COVID-19 i nfection MESHDadmitted to our hospital.Methods: Forty patients with severe or critical type of COVID 19 were evaluated for symptoms, signs and laboratory tests of vasculitis HP asculitis syndromes MESHDincluding r heumatoid MESHDfactor (RF), anti-nuclear antibody SERO (ANA), anti dsDNA, c and p anti-neutrophilic cytoplasmic antibody SERO (c ANCA and p ANCA) and complement levels. Descriptive statistics methods were used to describe the clinical / laboratory findings.Results: Forty patients with severe to c ritical illness MESHDwere enrolled in the study. The mean age TRANS of the patients was 48.5 ± 9.8 years. All patients had pulmonary involvement in lung CT scan. Lymphopenia HP ymphopenia MESHDin 19 (47.5%), raised creatinine in 8(20%) and hyperbilirubinemia HP yperbilirubinemia MESHDin 19(47.5%) of patients were seen. Vasculitis HP asculitis laboratory MESHDtest results included: RF in 2 patients, ANA in 3 patients and ANCA in one patient. 17(42.5%) of patients had hypocomplementemia in one or more complement tests. Of the four patients who were expired, three had a decrease in complement.Conclusion: In 17 of patients (42.5%) we detected low complement levels. A decrease in complement levels may predict a critical state of the disease. Therefore, measuring its levels may be helpful in making earlier decisions to initiate disease-suppressing treatments, including corticosteroids and IVIG.

    Background: Compared with Severe Acute Respiratory Syndrome MESHD(SARS) and Middle East Respiratory Syndrome(MESR), Corona Virus Disease MESHD 2019(COVID-19) spread more rapidly and widely. The population was generally susceptible. However, reports on pregnant women infected with SARS-CoV-2 were very limited. By sharing the clinical characteristics, treatments and outcomes of 18 patients with COVID-19 during late pregnancy, we hoped to provide some references for obstetric treatment and management.Methods: A total of 18 patients with COVID-19 treated in Renmin Hospital of Wuhan University were collected. The epidemiological characteristics, clinical manifestations, laboratory tests, chest CT and pregnancy outcomes were performed for analysis.Results: 1. 18 cases of late pregnancy infected with SARS-CoV-2 pneumonia MESHD pneumonia HP were delivered at 35 + 5 weeks to 41 weeks. According to the clinical classification of COVID-19, 1 case was mild type, 16 cases were ordinary type, and 1 case was severe type. 2. According to Imaging examinations: 15 (83%) cases showed unilateral or bilateral pneumonia HP pneumonia MESHD, 2 (11%) cases had pulmonary infection MESHD with pleural effusion HP pleural effusion MESHD, and 1 (6%) case had no abnormal imaging changes. 8 (44%) cases were positive and 10 (56%) cases were negative for nasopharyngeal-swab tests of SARS-CoV-2. 3. Among the 18 newborns, there were 3 (17%) premature infants, 1 (6%) case of mild asphyxia MESHD, 5 (28%) cases of bacterial pneumonia MESHD pneumonia HP, 1 (6%) case of gastrointestinal bleeding MESHD, 1 (6%) case of necrotizing enteritis MESHD, 2 (11%) cases of hyperbilirubinemia HP hyperbilirubinemia MESHD and 1 (6%) case of diarrhea HP diarrhea MESHD. All the newborns were negative for the first throat swab test of SARS-CoV-2 after birth. 4. Follow-up to Mar 7, 2020, no maternal and neonatal deaths MESHD occurred.Conclusions: The majority of patients in late term pregnancy with COVID-19 were of ordinary type, and they less likely developed into critical pneumonia HP pneumonia MESHD after early isolation and antiviral treatment. Vertical transmission TRANS of SARS-CoV-2 was not detected, but the proportion of neonatal bacterial pneumonia MESHD pneumonia HP was higher than other neonatal diseases in newborns.
