    Background: Coronavirus disease MESHD 2019 (COVID-19) is a potentially life-threatening contagious disease MESHD disease which has spread TRANS which has spread all over the world. Risk factors for the clinical outcomes of COVID-19 pneumonia MESHD pneumonia HP in intensive care unit (ICU) have not yet been well determined. Methods: In this retrospective, single-centered, observational study, we consecutively included 47 patients with confirmed COVID-19 who were admitted to the ICU of Leishenshan Hospital in Wuhan, China, from February 24 to April 5, 2020. Clinical characteristics and outcomes were collected and compared between survivors and non-survivors. Multivariable logistic regression was used to explore the risk factors associated with death MESHD in patients of COVID-19.Results: The study cohort included 47 adult TRANS patients with a median age TRANS of 70.55±12.52 years, and 30 (63.8%) patients were men. Totally 15 (31.9%) patients died. Compared with survivors, non-survivors were more likely to develop septic shock MESHD shock HP (6 [40%] patients vs 3 [9.4%] patients ), disseminated intravascular coagulation MESHD disseminated intravascular coagulation HP (3 [21.4%] vs 0), and had higher score of APACHE II (25.07±8.03 vs 15.56±5.95), CURB-65 (3[2-4] vs 2[1-3]), Sequential Organ Failure Assessment (SOFA) (7[5-9] vs 3[1-6]), higher level of D-dimer (5.74 [2.32-18] vs 2.05 [1.09-4.00] ) and neutrophil count (9.4[7.68-14.54] vs 5.32[3.85-9.34] ). SOFA score (OR 1.47, 1.01–2.13; p=0.0042) and lymphocyte count (OR 0.02, 0.00–0.86; p=0.042) on admission were independently risk factors for mortality. Patients with higher lymphocyte count (>0.63×109/L) and lower SOFA score ≤4 on admission had a significantly well prognosis than those with lower lymphocyte count (≤0.63×109/L) and higher SOFA score >4 in overall survival.Conclusions: Higher SOFA score and lower lymphocyte count on admission were associated with poor prognosis of patients with COVID-19 in ICU. Lymphocyte count may serve as a promising prognostic biomarker.

    In Coronavirus disease MESHD 2019 (COVID-19) subjects, recent evidence suggests the presence of unique coagulation abnormalities HP. In this study, we performed clot waveform analyses to investigate whether specific modulations are observed in COVID-19 subjects. We analyzed the second derivative of the absorbance in routine APTT tests performed using an ACL-TOP system. We observed high frequencies of abnormal patterns in APTT second-derivative curves that could be classified into an early shoulder type, a late shoulder type, or a biphasic type, high maximum first-derivative and second-derivative peak levels, and a low minimum second-derivative peak level in COVID-19 subjects. These modulations were not observed in subjects with disseminated intravascular coagulation MESHD disseminated intravascular coagulation HP. These abnormal patterns are also observed in patients with lupus anticoagulant HP, hemophilia MESHD, or factor IX deficiency. The plasma SERO fibrinogen levels might also be involved in the abnormal APTT waveforms, especially the high maximum first-derivative and second-derivative peak levels. The abnormal patterns in the APTT second-derivative curves appear with highest frequency at around 2 weeks after the onset of COVID-19 and were not associated with the severity of COVID-19. These results suggest the possible presence of a specific abnormal coagulopathy in COVID-19.

    Severe disease MESHD caused by the SARS-CoV coronavirus is characterized by patients presenting with respiratory distress HP associated with a systemic inflammatory response syndrome MESHD (cytokine storm). Sixteen to thirty percent of COVID-19 patients also have gastrointestinal symptoms. Here we present three cases of COVID-19 who developed colonic ischemia MESHD. Three males TRANS aged TRANS 76, 68 and 56 with respiratory distress HP and receiving mechanical ventilation presented episodes of rectal bleeding, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia MESHD and pneumoperitoneum MESHD.One patient (case 2) underwent surgery in which perforation of the gangrenous cecum and colonic ischemia MESHD was confirmed.In all three patients D-dimer levels were markedly increased (2170, 2100 and 7360 ng/mL). All three patients died shortly after diagnosis.In severe COVID-19 disease MESHD, the pathogenic cause has increasingly become attributed to the development of disseminated intravascular coagulation MESHD disseminated intravascular coagulation HP secondary to the systemic inflammatory response.
