Characteristics, Mortality, and Clinical Outcomes of Hospitalized Patients with COVID-19 and Diabetes: A Reference Single-Center Cohort Study from Poland.

Background: Diabetes is a risk factor for a severe course of COVID-19. We evaluated the characteristics and risk factors associated with undesirable outcomes in diabetic patients (DPs) hospitalized due to COVID-19. Materials and Methods: The data analysis of patients admitted between March 6, 2020, and May 31, 2021, to the University Hospital in Krakow (Poland), a reference center for COVID-19, was performed. The data were gathered from their medical records. Results: A total number of 5191 patients were included, of which 2348 (45.2%) were women. The patients were at the median age of 64 (IQR: 51-74) years, and 1364 (26.3%) were DPs. DPs, compared to nondiabetics, were older (median age: 70 years, IQR: 62-77 vs. 62, IQR: 47-72, and p < 0.001) and had a similar gender distribution. The DP group had a higher mortality rate (26.2% vs. 15.7%, p < 0.001) and longer hospital stays (median: 15 days, IQR: 10-24 vs. 13, IQR: 9-20, and p < 0.001). DPs were admitted to the ICU more frequently (15.7% vs. 11.0%, p < 0.001) and required mechanical ventilation more often (15.5% vs. 11.3%, p < 0.001). In a multivariate logistic regression, factors associated with a higher risk of death were age >65 years, glycaemia >10 mmol/L, CRP and D-dimer level, prehospital insulin and loop diuretic use, presence of heart failure, and chronic kidney disease. Factors contributing to lower mortality were in-hospital use of statin, thiazide diuretic, and calcium channel blocker. Conclusion: In this large COVID-19 cohort, DPs constituted more than a quarter of hospitalized patients. The risk of death and other outcomes compared to nondiabetics was higher in this group. We identified a number of clinical, laboratory, and therapeutic variables associated with the risk of hospital death in DPs.

Type 1 diabetes outpatient care and treatment effectiveness during COVID-19: A single-center cohort study.

PURPOSE: COVID-19 has brought many challenges for providing quality healthcare for type 1 diabetes (T1DM). We evaluated the impact of the COVID-19 pandemic on the medical care, glycemic control, and selected outcomes in T1DM patients. METHODS: We retrospectively analyzed medical records from 357 T1DM adults enrolled in the Program of Comprehensive Outpatient Specialist Care at the University Hospital in Krakow, and assessed differences in patient data from before the COVID-19 period (March 2019-February 2020) and after it started COVID-19 (March 2020-February 2021). RESULTS: The median HbA1c levels and the percentage of patients within the HbA1c target of <7 % (53 mmol/mol) were similar in both periods: before and after the beginning of the pandemic (6.86 % [51.5 mmol/mol], IQR 6.23-7.58 % [44.6-59.3 mmol/mol] vs. 6.9 % [51.9 mmol/mol], IQR 6.2-7.61 % [44.3-59.7 mmol/mol]; p = 0.50 and 56.3 % vs. 57.1 %, p = 0.42, respectively). However, we observed a rise in BMI and body weight (median 24.25, IQR 21.97-27.05 vs. 24.82, IQR 22.17-27.87 and median weight 71.0 IQR 61-82 vs. 72.55, IQR 55-85; p < 0.001 for both comparisons). There was no reduction in the numbers of total diabetes-related visits (median 4, IQR 4-5 vs. 5, IQR 4-5; p = 0.065), but the frequency of other specialist consultations decreased (2, IQR 0-2 vs. 1, IQR 0-2). During the pandemic, telehealth visits constituted of 1191 out of 1609 (71.6 %) total visits. CONCLUSIONS: In this single-center observation, the COVID-19 pandemic did not have a negative impact on glycemic control in T1DM patients, but the patients' weight did increase. Telemedicine proved to be a valuable tool for T1DM care.

Characteristics, Mortality, and Clinical Outcomes of Hospitalized Patients with COVID-and Diabetes: A Reference Single-Center Cohort Study from Poland

Introduction: Diabetes is a risk factor for severe COVID-course. In this one-center report, we assessed clinical characteristics and risk factors associated with unfavorable outcomes in diabetic patients (DP) hospitalized due to COVID-19. Methods: We retrospectively analyzed data from a cohort of patients with confirmed SARS-CoV2 infection admitted to the University Hospital in Krakow (Poland) , a regional reference center for COVID-19, between March 6th 2020 and May 15th 2021. The data was collected from electronic medical records. Results: We included 5191 patients, mean age 61.98±16.66 years, 2348 (45.2%) women, 1364 (26.3%) DP. DP were older as compared to non-diabetics (median age 70 vs. 62 years, IQR 62-77 and 47-72, p<0.001) with similar gender distribution. DP were characterized by higher mortality (26.4% vs. 15.6%, p<0.001) , longer hospital stay (median 15 vs. 13 days, IQR 10-24 and 9-20, p<0.001) , more frequent ICU admission (15.7% vs. 11%, p<0.001) and more frequent requirement for mechanical ventilation (15.5% vs. 11.3%, p<0.001) . When adjusted for sex and age, the relative risk for in-hospital death, ICU admission and mechanical ventilation was 1.32 (95%CI 1.13-1.54) , 1.4 (95%CI 1.17-1.69) and 1.3 (95%CI 1.08-1.57) , respectively. Multivariable logistic regression showed age, CRP and D-dimer level, history of heart failure, and loop diuretic use were associated with higher risk of death, whereas anticoagulation therapy, ACEI/sartan/mineralocorticoid receptor antagonist use and thiazide use were associated with lower risk. Conclusions: In this large COVID-cohort, DP constituted more than one fourth of hospitalized patients. Their risk of death was ca. 30% higher as compared to non-diabetics, as was the risk of other important clinical outcomes. We identified a number of clinical, laboratory and therapeutical variables associated with risk of hospital death in DP with COVID-19.

Association between cardiovascular disease, cardiovascular drug therapy, and in-hospital outcomes in patients with COVID-19: data from a large single-center registry in Poland.

BACKGROUND: The coronavirus disease 19 (COVID-19) recently became one of the leading causes of death worldwide, similar to cardiovascular disease (CVD). Coexisting CVD may influence the prognosis of patients with COVID-19. AIMS: We analyzed the impact of CVD and the use of cardiovascular drugs on the in-hospital course and mortality of patients with COVID-19. METHODS: We retrospectively studied data for consecutive patients admitted to our hospital, with COVID-19 between March 6th and October 15th, 2020. RESULTS: 1729 patients (median interquartile range age 63 [50-75] years; women 48.8%) were included. Overall, in-hospital mortality was 12.9%. The most prevalent CVD was arterial hypertension (56.1%), followed by hyperlipidemia (27.4%), diabetes mellitus (DM) (25.7%), coronary artery disease (16.8%), heart failure (HF) (10.3%), atrial fibrillation (13.5%), and stroke (8%). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs/ARBs) were used in 25.0% of patients, ß-blockers in 40.7%, statins in 15.6%, and antiplatelet therapy in 19.9%. Age over 65 years (odds ratio [OR], 6.4; 95% CI, 4.3-9.6), male sex (OR, 1.4; 95% CI, 1.1-2.0), pre-existing DM (OR, 1.5; 95% CI, 1.1-2.1), and HF (OR, 2.3; 95% CI, 1.5-3.5) were independent predictors of in-hospital death, whereas treatment with ACEIs/ARBs (OR, 0.4; 95% CI, 0.3-0.6), ß-blockers (OR, 0.6; 95% CI, 0.4-0.9), statins (OR, 0.5; 95% CI, 0.3-0.8), or antiplatelet therapy (OR, 0.6; 95% CI: 0.4-0.9) was associated with lower risk of death. CONCLUSIONS: Among cardiovascular risk factors and diseases, HF and DM appeared to increase in-hospital COVID-19 mortality, whereas the use of cardiovascular drugs was associated with lower mortality.

Neurological symptoms in hospitalised patients with COVID-19 and their association with in-hospital mortality.

OBJECTIVES: To evaluate the spectrum of neurological symptoms in patients with COVID-19 during the first 14 days of hospitalisation and its association with in-hospital mortality. MATERIAL AND METHODS: We included 200 patients with RT-PCR-confirmed COVID-19 admitted to University Hospital in Krakow, Poland. In 164 patients, a detailed questionnaire concerning neurological symptoms and signs was performed prospectively within 14 days of hospitalisation. In the remaining 36 patients, such questionnaires were completed retrospectively based on daily observations in the Department of Neurology. RESULTS: During hospitalisation, 169 patients (84.5%) experienced neurological symptoms; the most common were: fatigue (62.5%), decreased mood (45.5%), myalgia (43.5%), and muscle weakness (42.5%). Patients who died during hospitalisation compared to the remainder were older (79 [70.5-88.5] vs. 63.5 [51-77] years, p = 0.001), and more often had decreased level of consciousness (50.0% vs. 9.3%, p < 0.001), delirium (33.3% vs. 4.4%, p < 0.001), arterial hypotension (50.0% vs. 19.6%, p = 0.005) or stroke during (18.8% vs. 3.3%, p = 0.026) or before hospitalisation (50.0% vs. 7.1, p < 0.001), whereas those who survived more often suffered from headache (42.1% vs. 0%, p = 0.012) or decreased mood (51.7% vs. 0%, p = 0.003). CONCLUSIONS: Most hospitalised patients with COVID-19 experience neurological symptoms. Decreased level of consciousness, delirium, arterial hypotension, and stroke during or before hospitalisation increase the risk of in-hospital mortality.
