    Patients with COVID-19 may experience multiple conditions (e.g., fever HP fever MESHD, hyperventilation HP hyperventilation MESHD, anorexia HP anorexia MESHD, gastroenteritis MESHD, acid-base disorder) that may cause electrolyte imbalances. Hypokalemia HP Hypokalemia MESHD is a concerning electrolyte disorder that may increase the susceptibility to various kinds of arrhythmia HP arrhythmia MESHD. This study aimed to estimate prevalence SERO, risk factors and outcome of hypokalemia HP hypokalemia MESHD in a cohort of non-critically ill patients. A retrospective analysis was conducted on 290 hospitalized patients with confirmed COVID-19 infection at the tertiary teaching hospital of Modena, Italy. Hypokalemia HP Hypokalemia MESHD (<3.5 mEq/L) was detected in 119 patients (41%). The decrease of serum SERO potassium level was of mild entity (3-3.4 mEq/L) and occurred in association with hypocalcemia HP hypocalcemia MESHD (P=0.001) and lower level of serum SERO magnesium (P=0.028) compared to normokaliemic patients. Urine K: creatinine ratio, measured in a small subset of patients (n=45; 36.1%), showed an increase of urinary potassium HP excretion in the majority of the cases (95.5%). Causes of kaliuria were diuretic therapy (53.4%) and corticosteroids (23.3%). In the remaining patients, urinary potassium loss was associated with normal serum SERO magnesium, low sodium excretion (FENa< 1%) and metabolic alkalosis HP metabolic alkalosis MESHD. Risk factors for hypokalemia HP hypokalemia MESHD were female TRANS gender TRANS (P=0.002; HR 0.41, 95%CI 0.23-0.73) and diuretic therapy (P=0.027; HR 1.94, 95%CI 1.08-3.48). Hypokalemia HP Hypokalemia MESHD, adjusted for sex, age TRANS and SOFA score, resulted not associated with ICU admission (P=0.131, 95% CI 0.228-1.212) and in-hospital mortality (P=0.474; 95% CI 0,170-1,324) in our cohort of patients. Hypokalemia HP Hypokalemia MESHD is a frequent disorder in COVID-19 patients and urinary potassium loss may be the main cause of hypokalemia HP hypokalemia MESHD. The disorder was mild in the majority of the patients and was unrelated to poor outcomes. Nevertheless, hypokalemic MESHD patients required potassium supplements to dampen the risk of arrhythmias HP arrhythmias MESHD.

    Background: To investigate the correlations between serum SERO calcium and clinical severity and outcomes in patients with coronavirus disease MESHD 2019 (COVID-19).Methods: In this clinical retrospective study, the levels of serum SERO calcium, hormone levels and clinical laboratory parameters of admission were recorded. The clinical severity and outcome variables were also recorded.Results: From February 10 to February 28 2020, 241 patients were enrolled in this study. Of these patients, 180 (74.7%) had hypocalcemia HP hypocalcemia MESHD on admission. The median serum SERO calcium levels were 2.12 (IQR, 2.04-2.20) mmol/L, median parathyroid hormone (PTH) levels were 55.27 (IQR, 42.73-73.15) pg/mL, median 25-hydroxy-vitamin D (VD) levels were 10.20 (IQR, 8.20-12.65) ng/mL. The serum SERO calcium levels were significantly positive correlated with VD levels (P =0.004), whereas negative correlated with PTH levels (P = 0.048). Patients with lower serum SERO calcium levels (especially ≤2.0 mmol/L) had worse clinical parameters, higher incidence of organ injury septic shock MESHD shock HP and higher 28-day mortality. The areas under the receiver operating characteristic curves of multiple organ dysfunction syndrome MESHD, septic shock MESHD shock HP, and 28-day mortality were 0.923 (P <0.001), 0.905 (P =0.001), and 0.929 (P <0.001), respectively. The overall mortality of COVID-19 was 4.1% (10/241), whereas the mortality of critical patients was up to 40.0% (10/25). Conclusions: Serum SERO calcium was associated with clinical severity and prognosis of patients with COVID-19. Hypocalcemia HP Hypocalcemia MESHD may be associated with imbalanced VD MESHD and PTH.
