Hemoglobin, Journal Year: 2023, Volume and Issue: 47(3), P. 122 - 129

Published: May 4, 2023

On 11 March 2020, the World Health Organization (WHO) declared novel SARS-CoV-2 virus responsible for causing COVID-19, a global pandemic. The primarily targets respiratory system but can also affect other systems, notably hematological pathologies. Anemia, common hematologic disorder, is characterized by reduced oxygen-carrying capacity of red blood cells. existing literature has suspected link between anemia and severe COVID-19 cases. Researchers are currently investigating long-term complications in anemic patients, as these may play crucial role predicting patient prognosis. Anemic individuals at higher risk experiencing infections due to several contributing pathophysiological mechanisms, including thrombotic, hemorrhagic, autoimmune etiologies. primary effect mechanisms decrease circulating hemoglobin levels, reducing oxygen availability This exacerbates hypoxia caused COVID-19-induced acute distress syndrome (ARDS). review offers comprehensive overview evidence regarding patients.

Predictivity of the Prognostic Nutritional Index and Systemic Inflammation Index for All-Cause In-Hospital Mortality in Geriatric and Adult COVID-19 Inpatients

Journal of Clinical Medicine, Journal Year: 2024, Volume and Issue: 13(15), P. 4466 - 4466

Published: July 30, 2024

Background: The prognostic nutritional index (PNI) and the systemic immune inflammation (SII) have been used as simple risk-stratification predictors for COVID-19 severity mortality in general population. However, associations between these indices might differ due to age-related changes such inflammaging several comorbid conditions older patients. Therefore, we aimed compare predictivity of PNI SII among hospitalized patients under 65 years old. Methods: Patients with from March 2020 December were retrospectively included. calculated hospital records within first 48 h after admission. Data evaluated whole group according age groups (≥65 < years). Receiver operating characteristic curves drawn evaluate SII. Results: Out 407 included this study, 48.4% (n = 197) patients, 51.6% 210) For mortality, area curve (AUC) adult (<65 years) was 0.706 (95% CI 0.583–0.828) (p 0.003) 0.697 0.567–0.827) 0.005), respectively.

Analysis of Survival Modification by Furosemide Use in a Cohort of Hospitalized COVID-19 Patients with Severe or Critical Disease in Mexico: Due to Its Chemical Structure, Furosemide Is More than Just a Diuretic

In the ongoing fight against Coronavirus Disease 2019 (COVID-19), researchers are exploring potential treatments to improve outcomes, especially in severe cases. This includes investigating repurposing of existing medications, such as furosemide, which is widely available. study aimed evaluate impact furosemide on mortality rates among COVID-19 patients with or critical illness. We assessed a cohort 515 hospitalized adults who experienced high rate 43.9%. Using multivariate analysis adjusted risk ratios (AdRRs), factors like smoking (AdRR 2.48, 95% CI 1.53–4.01, p < 0.001), Pneumonia Severity Index (PSI) score 7.89, 5.82–10.70, mechanical ventilation 23.12, 17.28–30.92, neutrophilia 2.12, 1.52–2.95, and an elevated neutrophil-to-lymphocyte ratio (NLR) 2.39, 1.72–3.32, 0.001) were found increase risk. contrast, vaccination use associated reduced 0.58, = 0.001 0.60, 0.008; respectively). Furosemide showed pronounced survival benefit less disease (PSI 120) those not hemodialysis, significantly lower users (3.7% vs. 25.7%). A Kaplan–Meier confirmed longer better oxygenation levels treated furosemide. Furthermore, Structure–Activity Relationship revealed that furosemide’s sulfonamide groups may interact cytokine sites tumor necrosis factor-alpha (TNF-α) interleukin-6 (IL-6), potentially explaining its beneficial effects management. These findings suggest could be treatment option certain patient groups, enhancing improving oxygenation.

Azvudine has been approved in China for the treatment of COVID-19 patients. Previous studies have suggested a correlation between high levels lactate dehydrogenase (LDH) and severity COVID-19. However, impact LDH patients receiving remains unclear.In this retrospective cohort study, we analyzed data 351 hospitalized who were consecutively treated with Azvudine, or without levels. The clinical features, strategies prognosis collected analyzed.Among (119 high-LDH levels), median age was 69 years (range 58-78), 213 (60.7%) male. Common symptoms included cough (86.0%), expectoration (73.5%), fever (69.8%), polypnea (47.6%) poor appetite (46.4%). Patients exhibited significantly elevated leucocyte neutrophil counts, level myocardial enzymes, as well higher inflammatory markers such interleukin-6, interleukin-10, procalcitonin, C reactive protein, ferritin, prolonged erythrocyte sedimentation rate upon admission. had rates corticosteroid therapy, non-invasive invasive mechanical ventilation, worsened death (2.5% vs. 0%).
