    Background As the COVID-19 epidemic is wreaking havoc with a staggering number of infections MESHD and fatalities worldwide, digestive symptoms are increasingly coming to the limelight. However, the data on the extent of gut and liver involvement has been variable and somewhat conflicting.Methods We identified 711 adults TRANS who had tested positive for COVID-19 at Richmond University Medical Center in New York between March 13 and May 13, 2020. We analyzed their clinical and laboratory data from electronic medical records.Results The average age TRANS of the patients was 60.5 years; 55% were men. 27.1% reported a gastrointestinal ( GI MESHD) symptom and 56.9% had at least one abnormal liver enzyme. The most common was diarrhea HP diarrhea MESHD with a frequency of 17.3% followed by nausea HP nausea MESHD 16.2% and vomiting HP vomiting MESHD/ anorexia HP anorexia MESHD 13.7%. Abdominal pain HP Abdominal pain MESHD 5.6%, dysgeusia MESHD 3.2%, and GI bleeding MESHD 2.2% was the least common. Symptoms were mostly mild and lasted 3-5 days. The liver function was deranged in more than half of the patients. AST alone was elevated in 16.6%, both AST/ALT 15.7%, alkaline phosphatase 23%, and bilirubin 10%. Potential confounders were rare but included preexisting liver disease MESHD and hepatotoxic MESHD medications. Prothrombin time (PT) was mildly elevated in 13.4%. The lipase was elevated in 2.4% without upper abdominal pain HP abdominal pain MESHD. In 75%-90% of cases, liver test abnormalities MESHD were mild (1.5-3 x normal). Overall, 86.6% of patients were admitted primarily with respiratory failure HP respiratory failure MESHD and 28.5% died of their illness.Conclusions 27% of COVID-19 patients experienced a digestive disturbance and >55% showed a predominantly mild degree of liver dysfunction MESHD and cholestasis HP cholestasis MESHD.

    Context: Originally developed for the treatment of human immunodeficiency virus MESHD immunodeficiency HP virus ( HIV MESHD), the antiviral combination lopinavir/ritonavir (LPV/r) is being investigated for use against coronavirus disease (COVID-19). We present a case series raising safety and efficacy concerns in COVID-19 affected patients. Methods: We measured LPV trough concentrations in 12 patients treated at our center and reviewed their clinical charts for side effects known to occur in HIV MESHD patients. Results: Compared to established LPV trough concentrations in HIV MESHD treated patients, concentrations in COVID-19 affected patients were 3-fold greater (20.64 +/- 10.14 mcg/mL versus 6.25 mcg/mL). In addition, cholestasis HP cholestasis MESHD and dyslipidemia toxicity MESHD thresholds were exceeded in 12/12 and 11/12 patients respectively. No patients achieved the presumed therapeutic concentration. The side effects noted were mainly gastrointestinal symptoms (5/12, 42%), electrolytes imbalances (4/12, 33%), liver enzyme disturbances MESHD (5/12, 42%), and triglyceride elevations (2/12, 17%). Conclusion: None of our patients reached presumed therapeutic LPV concentrations despite experiencing side effects and exceeding cholestasis HP cholestasis MESHD and dyslipidemia toxicity MESHD thresholds. This raises concerns for the safety and efficacy of LPV/r. Clinicians should consider closely monitoring for side effects and not necessarily attribute them to COVID-19 itself.

    The aim of this study was to assess the key laboratory features displayed by coronavirus disease MESHD 2019 (COVID-19) inpatients which associated with mild, moderate, severe and fatal course of the disease and, through longitudinal follow-up, to understand the dynamics of COVID-19 pathophysiology. All SARS-CoV-2 positive patients admitted to the University Hospital in Motol between March and June 2020 were included in this study. Severe course of COVID-19 was associated with elevation of proinflammatory markers, efflux of immature granulocytes into peripheral blood SERO, activation of CD8 T cells, which infiltrate lungs, and transient liver disease MESHD. In particular, the elevation of serum SERO gamma-glutamyl transferase (GGT) and histological signs of cholestasis HP cholestasis MESHD were highly specific for patients with severe disease. In contrast, patients with fatal course of COVID-19 failed to upregulate markers of inflammation MESHD, showed dyscoordination MESHD of immune response and progressed towards acute kidney failure MESHD. COVID-19 is a disease with multi-organ affinity characterized by activation of innate and cellular adaptive immunity. Biliary lesion MESHD with elevation of GGT and organ-infiltration of IL-6 producing cells are defining characteristic for patients with fulminant disease.

    Background and Aims: Although abnormal liver chemistries are linked to higher risk of death related to coronavirus disease MESHD (COVID-19), liver manifestations may be diverse and even confused. Thus, we performed a meta-analysis of published liver manifestations and described the liver damage in COVID-19 patients with death MESHD or survival. Methods: We searched PubMed, Google Scholar, medRxiv, bioRxiv, Cochrane Library, Embase, and three Chinese electronic databases through April 22, 2020. We analyzed pooled data on liver chemistries stratified by the main clinical outcome of COVID-19 using a fixed or random-effects model. Results: In the meta-analysis of 18 studies, which included a total of 2,862 patients, the pooled mean alanine aminotransferase (ALT) was 30.9 IU/L in the COVID-19 patients with death MESHD and 26.3 IU/L in the COVID-19 patients discharged alive (p < 0.0001). The pooled mean aspartate aminotransferase (AST) level was 45.3 IU/L in the COVID-19 patients with death MESHD while 30.1 IU/L in the patients discharged alive (p < 0.0001). Compared with the discharged alive cases, the dead cases tended to have lower albumin levels but longer prothrombin time, and international standardized ratio. Conclusions: In this meta-analysis, according to the main clinical outcome of COVID-19, we comprehensively described three patterns of liver impairment MESHD related to COVID-19, hepatocellular injury MESHD, cholestasis HP cholestasis MESHD, and hepatocellular disfunction. Patients died from COVID-19 tend to have different liver chemistries from those are discharged alive. Close monitoring of liver chemistries provides an early warning against COVID-19 related death.

    Background & Aims: Cumulating observations have indicated that COVID-19 patients undergo different patterns of abnormal liver chemistries. We performed a meta-analysis of published liver manifestations and tried to describe the liver damage MESHD. Methods: We searched PubMed, google scholar, Embase, Cochrane Library, medRxiv, bioRxiv, and three Chinese electronic databases through April 18, 2020 according to the Preferred Reporting Items for Meta-Analyses. We analyzed pooled data on liver chemistries stratified by the severity of COVID-19 using a fixed or random effects model. Results: In a meta-analysis of 37 studies, comprising 6,235 patients, the pooled mean of ALT was 36.4 IU/L in the severe cases of COVID-19 while 27.8 IU/L in the non-severe cases (95% CI: -9.4- -5.1, p<0.0001). Pooled average of AST was 46.8 IU/L in the severe cases while 30.4 IU/L in the non-severe cases (95% CI: -15.1- -10.4, p<0.0001). Compared with the non-severe cases, the severe cases tended to have higher {gamma}-Glutamyltransferase while lower albumin. Conclusions: In this meta-analysis, we comprehensively described three patterns of liver impairment MESHD related to COVID-19, including hepatocellular injury MESHD, cholestasis HP cholestasis MESHD, and synthetic disfunction, according to the severity of the COVID-19. Patients with abnormal liver tests are at higher risks of progressing to severe disease. Close monitoring on liver chemistries helps to early warn against disease progression.

    Background:  COVID-19 virus it is going to be pandemic all around the world. There is still limited scientific evidence on the manifestations and potential impact of this virus on pregnancy.Case presentation She was a 38 year-old triplet pregnant with a history of primary infertility HP infertility MESHD and had become pregnant by induction ovulation and a history of hypothyroidism HP hypothyroidism MESHD and also a history of gestational diabetes MESHD. She was hospitalized at 29 weeks and 2 days gestational age TRANS due to elevated liver enzymes MESHD and finally based on a probable diagnosis of gestational cholestasis MESHD cholestasis HP, she was treated with ursodeoxycholic acid. On the first day after hospitalization, a sonography was performed in which biophysical scores and amniotic fluid were found normal in all three fetuses with normal Doppler findings in two fetuses and increased umbilical artery resistance (PI>95%) in one fetus. Four days after hospitalization, she developed fever HP fever MESHD, cough HP cough MESHD and myalgia HP myalgia MESHD and her covid-19 test was positive. After maternal infection MESHD with the virus, exacerbated placental insufficiency MESHD occurred in two of the fetuses so that absent umbilical artery end diastolic flow occurred rapidly in two fetuses and finally, six days later, she underwent cesarean section due to rapid exacerbated placental insufficiency MESHD and declined biophysical score in two of fetuses. Covid-19 test of nasopharyngeal swabs was negative for first and third babies and positive for second baby .The first and third babies died 3 and 13 days after birth respectively duo to collapsed white lung and sepsis HP sepsis MESHD. The second baby was discharged with a good general condition. The mother was discharged three days after cesarean section. She had no fever HP fever MESHD at discharge time and also she was in good general condition.Conclusions: It was a complicated triplet pregnancy, in which, after maternal infection MESHD with the Covid-19 virus, exacerbated placental insufficiency MESHD occurred in two of the fetuses, and another fetus had positive covid-19 virus test after birth. It sounds wise that in pregnancy infected by corona virus, in addition to managing the mother, special attention should also be given to the possibility of acute placental insufficiently MESHD and subsequent fetal hypoxia MESHD and also probability of vertical transmission TRANS.
