Comorbidities and outcomes among patients hospitalized with COVID-19 in Upper Egypt.

Background: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 had consistently been reported as risk factors for unfavorable outcome. We aimed to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for intensive care unit (ICU) admission. Four hundred and thirty-nine adult patients who are admitted through (June and July 2020) in our University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or probable case. Results: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and lower respiratory tract (LRT) symptoms such as dyspnea were significantly higher in patients with comorbidities (P < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of cardiovascular diseases (CVD) cases were admitted in ICU followed by diabetes mellitus (DM) cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 versus 10.7%, P < 0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% versus 81%, P < 0.001) and death rate was significantly higher in cases with comorbidities (P < 0.001) . The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease (P < 0.002 and 0.001, respectively). Conclusions: Association of cardiovascular comorbid conditions including hypertension or neurological diseases including old cerebrovascular strokes together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity.

Hemodynamic and antiemetic effects of prophylactic hyoscine butyl-bromide during cesarean section under spinal anesthesia: a randomized controlled trial.

BACKGROUND: Abrupt bradycardia and hemodynamic instability during spinal anesthesia for cesarean section are not uncommon and are considered as one of the primary causes of intraoperative nausea and vomiting (IONV). We hypothesized that prophylactic use of hyoscine butyl-bromide (HBB) could improve hemodynamics and reduce IONV in parturients undergoing cesarean section. METHODS: A randomized, double-blind placebo-controlled trial was carried out in a tertiary university hospital, patients scheduled for elective cesarean section were equally randomized to receive either IV HBB 20 mg in 1 ml (Hyoscine group) or the same volume of 0.9% saline (Control group), one minute after spinal anesthesia. The primary endpoint was the incidence of intraoperative bradycardia (HR < 50 beats min-1). Secondary endpoints included changes in mean arterial blood pressure (MAP), the incidence of Intraoperative and Postoperative nausea or vomiting (IONV & PONV), the fetal heart rate and, Apgar score. RESULTS: Of the 160 subjects randomized, 80 received HBB and 80 received placebo. There was a significant reduction in the incidence of the primary endpoint of intraoperative bradycardia (HR < 50 beats min-1) in the Hyoscine group (0% vs 10%; OR = 0.05, 95% CI = [0.003, 0.93]; P = 0.004) compared with placebo. MAP showed an insignificant difference between groups over time. HBB significantly decreased incidences of IONV and PONV (p = 0.002 & 0.004) respectively. CONCLUSIONS: In parturients undergoing cesarean section under spinal anesthesia, pretreatment with intravenous HBB was a safe measure for both the mother and the baby to reduce the risk of severe intraoperative bradycardia, but not hypotension. Furthermore, it was associated with less incidence of both IONV and PONV. TRIAL REGISTRATION: https://clinicaltrials.gov/ct2/show/NCT04069078.

Impact of comorbidities on COVID-19 outcome.

BACKGROUND AND AIMS: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 have consistently been reported as risk factors for unfavorable prognosis. We aim at this study to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for ICU admission or decease. METHODS: Four hundreds and thirty nine adult patients who are admitted through (June and July 2020) in Assiut and Aswan University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or Probable case. Detection of SARS-CoV-2 RNA was done by (TaqManâ"¢ 2019-nCoV Control Kit v1 (Cat. No. A47532) supplied by QIAGEN, Germany on the Applied Biosystem 7500 Fast RT PCR System, USA. RESULTS: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and LRT symptoms such as dyspnea were significantly higher in patients with comorbidities (P < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of CVD cases were admitted in ICU followed by DM cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 vs. 10.7%, P<0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% vs. 81%, P<0.001) and death rate was significantly higher in cases with comorbidities (P< 0.001). The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease (P<0.002 and 0.001 respectively). CONCLUSION: Association of cardiovascular comorbid conditions including hypertension or neurological diseases together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity.

Effects of terlipressin infusion during hepatobiliary surgery on systemic and splanchnic haemodynamics, renal function and blood loss: a double-blind, randomized clinical trial.

BACKGROUND: Terlipressin, in general, is a vasopressor which acts via V1 receptors. Its infusion elevates mean blood pressure and can reduce bleeding which has a splanchnic origin. The primary outcome was to assess the impact of intraoperative terlipressin infusion on portal venous pressure during hepatobiliary surgery; the 2ry outcomes included effects upon systemic hemodynamics, estimated blood loss, and postoperative renal functions. METHODS: This prospective randomized study involved 50 patients undergoing hepatobiliary surgery who were randomly and equally allocated into terlipressin group, or a control group. The terlipressin group received an initial bolus dose of (1 mg over 30 min) followed by a continuous infusion of 2 µg/kg/h throughout the procedure and gradually weaned over the first four postoperative hours, whereas the control group received the same volumes of normal saline. The portal venous pressure changes were measured directly through a portal vein angiocatheter. RESULTS: Portal pressure was significantly reduced over time in the terlipressin group only (from 17.88 ± 7.32 to 15.96 ± 6.55 mmHg, p < .001). Mean arterial blood pressure was significantly higher in the terlipressin group. Estimated blood loss was significantly higher in the control group than the terlipressin group (1065.7 ± 202 versus 842 ± 145.5 ml; p = 0.004), and the units of packed RBCs transfused were significantly higher in the control group ((0-2) versus (0-4) p = 0.003). There was no significant difference between groups as regards the incidence of acute kidney injury. CONCLUSION: Intraoperative infusion of terlipressin during hepatobiliary surgery was shown to improve intraoperative portal hemodynamics with subsequent reduction in blood loss.
