ABSTRACT

Background: The prevalence and mortality of sepsis in Internal Medicine Units (IMUs) is poorly understood as most of the data derive from studies conducted in Intensive Care Units. Aim of SEpsis Management in INternal medicine Apulia (SEMINA) study was to determine the prevalence of sepsis and the characteristics and outcomes of patients with Sepsis-3 criteria admitted in Apulia's Internal Medicine Units for over six months. Methods: The SEpsis Management in INternal medicine of Apulia study was a prospective, multicentre, observational study. Adult admissions to the 13 Apulia Region's Internal Medicine Units between November 15, 2018 and May 15, 2019 were screened for sepsis according to the Sepsis-3 criteria. Medical data were collected in electronic case report form. Results: Out of 7,885 adult patients of the Internal Medicine Units, 359 (4.55%) fulfilled the inclusion criteria, and 65 of them (18.1%) met the septic shock criteria. The patients enrolled were elderly, suffering from chronic poly-pathologies and from cognitive and functional impairment. The respiratory system was the most common site of infection and the most common pathogens isolated from blood cultures were Staphylococcus spp., E. coli, Klebsiella spp., Enterococcus spp. and Acinetobacter spp. The in-hospital fatality rate was 31.2% and was significantly higher for septic shock. Sequential Organ Failure Assessment score, dementia and infections from Acinetobacter spp. were independent risk factors for mortality. Conclusions: A high prevalence of sepsis and a high fatality rate were detected in Apulia Region's Internal Medicine Units. The high fatality rate observed in our study could be related to the underlying diseases and to the vulnerability of elderly patients admitted to our Internal Medicine Units.

ABSTRACT

BACKGROUND: COVID-19 induces robust systemic inflammation. One of the main complications is the increased coagulation due to endotheliitis. There is an increased incidence of pulmonary embolism (PE) in COVID-19 patients. However, clinical characteristics for a strict analysis are yet to be determined. AIM: We evaluated oxygenation and characteristics in patients with COVID-19 PE (CPE). MATERIAL AND METHODS: We evaluated 215 COVID-19 patients from 1 January to 30 April 2021. We found 18 patients affected by PE (CPE, 50.0% males, aged 67.00 ± 10.86 years). As controls, we used data from patients affected by PE evaluated in our ward between 1 January 2015 and 31 December 2019 (64 patients, 53.1% males, aged 70.88 ± 16.44 years). All patients underwent a complete physical examination, pulmonary computerised tomography, laboratory tests, D-dimers and blood gas analysis at the time of diagnosis. RESULTS: There were no differences in laboratory tests nor in D-dimers between the two groups. In the CPE group we found a significantly increased pO2 (92.83 ± 42.52 vs. 76.11 ± 32.58 mmHg; p < 0.05), difference of oxygen between alveoli and arteries (A-aDO2; 169.3 ± 171.9 vs. 52.97 ± 39.65 mmHg; p < 0.05), and oxygen saturation % (97.06 ± 2.59 vs. 93.77 ± 5.53%; p < 0.05) compared to controls. No difference was found in pCO2 and the ratio between pO2 and percentage of inspired oxygen (P/F). Finally, a significantly decreased urate (3.67 ± 1.49 vs. 5.60 ± 2.10; p < 0.05) was found in CPE compared to controls. In CPE, platelets count presents an inverse correlation to P/F (r = -0.389, p = 0.02) but a direct correlation to A-aDO2 (r = 0.699, p = 0.001). No similar findings were present in controls. DISCUSSION: COVID-19 PE appears to have a different clinical setting. Reduced oxygenation described in PE may not to be considered as a sign of disease. The increased A-aDO2 may indicate that COVID-19 PE involved smaller vessels compared to classical PE. A possible diffuse capillary thrombosis could explain these results.

ABSTRACT

BACKGROUND: COVID-19 induces robust systemic inflammation. Patients with cardiovascular disease (CVD) are at an increased risk of death. However, much effort is being spent to identify possible predictors of negative outcomes in order to have a more specific clinical setting. CVD scores are a useful tool in evaluating risk of cardiovascular events. AIM: We evaluated oxygenation and characteristics in COVID-19 patients according to cardiovascular risk stratification performed using the Framingham risk score (FRS) for cardiovascular disease. MATERIALS AND METHODS: We evaluated 155 COVID-19 patients (110 males and 45 females, aged 67.43 ± 14.72 years). All patients underwent a complete physical examination, chest imaging, laboratory tests and blood gas analysis at the time of diagnosis. Seventeen patients died (10 males and 7 females, aged 74.71 ± 7.23 years) while the remaining 138 patients (100 males and 38 females, aged 66.07 ± 15.16 years) were alive at discharge. RESULTS: Deceased patients have an increased FRS compared to those that survived (27.37 ± 5.03 vs. 21.33 ± 9.49, p < 0.05). Compared to survivors, the deceased group presents with a significant increase in white blood cells (p < 0.05) and D-dimers (p < 0.05). There was no difference in pCO2, SO2, and in alveolar arteriolar oxygen difference (A-aDO2). On the contrary, in deceased patients there was an increased pO2 (p < 0.05) and a decreased ratio between oxygen inspired and pO2 (P/F; p < 0.05). FRS shows a negative correlation to P/F (r = 0.42, p < 0.05) in the deceased while no correlation was found in the survivors. No other correlation has been found with blood gas parameters or in the inflammation parameters evaluated in the two groups. DISCUSSION: CVD may be considered as a major risk factor for death in COVID-19 patients. The increased risk relates to a reduced lung capacity but it is not related to blood gas values. Similarly, CV risk score results are independent from the inflammatory status of the patients.
