Clinical and Personal Predictors of Helmet-CPAP Use and Failure in Patients Firstly Admitted to Regular Medical Wards with COVID-19-Related Acute Respiratory Distress Syndrome (hCPAP-f Study).

Acute Respiratory Distress Syndrome (ARDS) caused by COVID-19 is substantially different from ARDS caused by other diseases and its treatment is dissimilar and challenging. As many studies showed conflicting results regarding the use of Non-invasive ventilation in COVID-19-associated ARDS, no unquestionable indications by operational guidelines were reported. The aim of this study was to estimate the use and success rate of Helmet (h) Continuous Positive Airway Pressure (CPAP) in COVID-19-associated ARDS in medical regular wards patients and describe the predictive risk factors for its use and failure. In our monocentric retrospective observational study, we included patients admitted for COVID-19 in medical regular wards. hCPAP was delivered when supplemental conventional or high-flow nasal oxygen failed to achieve respiratory targets. The primary outcomes were hCPAP use and failure rate (including the need to use Bilevel (BL) PAP or oro-tracheal intubation (OTI) and death during ventilation). The secondary outcome was the rate of in-hospital death and OTI. We computed a score derived from the factors independently associated with hCPAP failure. Out of 701 patients admitted with COVID-19 symptoms, 295 were diagnosed with ARDS caused by COVID-19 and treated with hCPAP. Factors associated with the need for hCPAP use were the PaO2/FiO2 ratio < 270, IL-6 serum levels over 46 pg/mL, AST > 33 U/L, and LDH > 570 U/L; age > 78 years and neuropsychiatric conditions were associated with lower use of hCPAP. Failure of hCPAP occurred in 125 patients and was associated with male sex, polypharmacotherapy (at least three medications), platelet count < 180 × 109/L, and PaO2/FiO2 ratio < 240. The computed hCPAP-f Score, ranging from 0 to 11.5 points, had an AUC of 0.74 in predicting hCPAP failure (significantly superior to Call Score), and 0.73 for the secondary outcome (non-inferior to IL-6 serum levels). In conclusion, hCPAP was widely used in patients with COVID-19 symptoms admitted to medical regular wards and developing ARDS, with a low OTI rate. A score computed combining male sex, multi-pharmacotherapy, low platelet count, and low PaO2/FiO2 was able to predict hCPAP failure in hospitalized patients with ARDS caused by COVID-19.

Early reduction of estimated Glomerular Filtration Rate (eGFR) predicts poor outcome in acutely ill hospitalized COVID-19 patients firstly admitted to medical regular wards (eGFR-COV19 study).

BACKGROUND: Analysis of autopsy tissues obtained from patients who died from COVID-19 showed kidney tropism for SARS-COV-2, with COVID-19-related renal dysfunction representing an overlooked problem even in patients lacking previous history of chronic kidney disease. This study aimed to corroborate in a substantial sample of consecutive acutely ill COVID-19 hospitalized patients the efficacy of estimated GFR (eGFR), assessed at hospital admission, to identify acute renal function derangement and the predictive role of its association with in-hospital death and need for mechanical ventilation and admission to intensive care unit (ICU). METHODS: We retrospectively analyzed charts of 764 patients firstly admitted to regular medical wards (Division of Internal Medicine) for symptomatic COVID-19 between March 6th and May 30th, 2020 and between October 1st, 2020 and March 15th, 2021. eGFR values were calculated with the 2021 CKD-EPI formula and assessed at hospital admission and discharge. Baseline creatinine and GFR values were assessed by chart review of patients' medical records from hospital admittance data in the previous year. The primary outcome was in-hospital mortality, while ARDS development and need for non-invasive ventilation (NIV) and invasive mechanical ventilation (IMV) were the secondary outcomes. RESULTS: SARS-COV-2 infection was diagnosed in 764 patients admitted with COVID-19 symptoms. A total of 682 patients (age range 23-100 years) were considered for statistical analysis, 310 needed mechanical ventilation and 137 died. An eGFR value <60 mL/min/1.73 m2 was found in 208 patients, 181 met KDIGO AKI criteria; eGFR values at hospital admission were significantly lower with respect to both hospital discharge and baseline values (p < 0.001). In multivariate analysis, an eGFR value <60 mL/min/1.73 m2 was significantly associated with in-hospital mortality (OR 2.6, 1.7-4.8, p = 0.003); no association was found with both ARDS and need for mechanical ventilation. eGFR was non-inferior to both IL-6 serum levels and CALL Score in predicting in-hospital death (AUC 0.71, 0.68-0.74, p = 0.55). CONCLUSIONS: eGFR calculated at hospital admission correlated well with COVID-19-related kidney injury and eGFR values < 60 mL/min/1,73 m2 were independently associated with in-hospital mortality, but not with both ARDS or need for mechanical ventilation.

Prognostic role of Interleukin-6/lymphocytes ratio in SARS-CoV2 related pneumonia.

INTRODUCTION AND AIM: Interleukin-6 to lymphocyte (IL-6/Lym) ratio has been identified as a potential prognostic tool in patients with SARS-CoV2 related pneumonia. The aim of our study was to compare the prognostic power of IL-6/Lym ratio with other biomarkers in patients initially admitted in a non intensive unit and suffering for respiratory failure associated with SARS-CoV2 related pneumonia. MATERIALS AND METHODS: IL-6/Lym ratio, IL-6, D-Dimer, D-Dimer/fibrinogen ratio, fibrinogen, C-reactive protein (CRP), lymphocytes count and neutrophil/lymphocyte (N/L) ratio collected at hospital admission were tested as prognosticators of negative outcome, defined as combined endpoint in-hospital mortality and/or Intensive Care Unit (ICU) admission requiring oro-tracheal intubation (OTI). RESULTS: Study population encompassed two hundreds and twenty-three patients (46% females) with mean age ± DS 69.4 ± 13.3 years. Eighty-nine patients (39.9%) suffered for severe respiratory failure and required non invasive ventilation, helmets and/or high flow nasal cannula. Fourty-one patients (18.3%) died during hospital stay and/or required OTI. In these patients mean values of IL-6/Lym ratio, IL-6, CRP and N/L were significantly higher and lymphocytes count was significantly lower compared with patients discharged alive and/or not requiring OTI, while no difference was found in mean values of D-Dimer, D-Dimer/Fibrinogen ratio and fibrinogen. AUC (0.797, 95% CI: 0.738-0.848) of IL-6/Lym ratio was the highest compared with those of all the other analyzed biomarkers and the difference was significant with the exception of IL-6. At multivariate logistic regression IL-6/Lym ratio > 66.5 resulted the only independent biomarker associated with mortality and/or OTI (OR 5.65; 95% 1.63-19.54). CONCLUSION: IL-6/Lym ratio seems to be an optimal prognosticator in SARS-CoV2 related pneumonia. Its routinary use in COVID-19 patients could be warranted.

The home management of Artificial Nutrition: a survey among doctors and nurses.

BACKGROUND AND AIM OF THE WORK: The management of Artificial Nutrition (NA), especially in the home environment (HAN) requires specific skills in order to ensure the correct therapeutic education, prevention of complications and the provision of appropriate treatment to the person. The aim of this survey was to identify the perceptions of nurses and doctors, as well as comparing to their perceived competence in NA and the gap between their perceived versus actual knowledge and management methods. METHODS: This observational study was conducted in a Tuscan health region of Italy, involving 50 Home Care Services nurses and 50 general practitioners. Participants were asked to complete an online questionnaire that was constructed for purpose. RESULTS: The results show that for the management of the person with NA, both for doctors and for nurses show great variability in responses. Less than half of those providing care make assessments of nutritional status and dysphagia as well as the possibility of re-feeding by natural means in NA patients. Care providers expressed uncertainty as to which professional should carry out such assessments. A mismatch was also evident between the skills possessed and the self-assessments performed regarding their knowledge base of NA. Almost all of doctors of nurses indicated a desire to participate in training events relating to NA. CONCLUSIONS: The results highlight the need for caregivers to have specific operating protocols. The results also highlight the need to aim to work as a team, emphasizing the importance of basic communication as well as the need for clarity as to the responsibilities and roles of the professionals involved.Key words: Artificial Nutrition, Nurses, Doctors, home management, skills, training, team.

Complete resolution of primary sclerosing peritonitis ("abdominal cocoon") following long term therapy for Tropheryma whipplei: a case report and review of literature.

A 53-year-old man was admitted to our internal medicine unit with intestinal obstruction and signs of systemic inflammatory disease. Clinical history was unremarkable until a few months earlier, when he began suffering from Achilles tendonitis. Diagnostic procedures, including laparotomy, revealed diffuse thickening of the peritoneum resembling sclerosing encapsulating peritonitis. Biopsies showed reactive fibrosis. No known secondary causes were found and surgery was technically not feasible. Clinical conditions worsened daily until, on the basis of the overall spectrum of clinical and radiological findings, Whipple's disease was hypothesised and specific therapy administered, with prompt clinical improvement. Complete disappearance of the cocoon was demonstrated at 1 year clinical/ultrasound/computed tomography follow-up.
