RESUMEN

BACKGROUND: Studies regarding effectiveness of anakinra and tocilizumab treatments in coronavirus disease 2019 (COVID-19) have contradictory results. Furthermore, there is scarce comparative data regarding superiority of any agent. To further elucidate any superiority between these two agents, we retrospectively investigated and compared outcomes in hospitalized COVID-19 patients of our inpatient cohort who received anakinra or tocilizumab. METHODS: This study was designed as a single-center, retrospective, cross-sectional cohort study. Hospitalized patients with confirmed diagnosis of COVID-19 who had Brescia-COVID respiratory severity scale score ≥3 and hyperinflammation (defined as elevation of C reactive protein ≥50 g/L or ferritin ≥700 ng/mL) and received anakinra or tocilizumab in addition to standard care were enrolled in the study. Length of hospital stay after initiation of antiinflammatory treatment, need for mechanical ventilation, need for intensive care unit admission, mortality were set as primary outcomes and compared between tocilizumab and anakinra recipients after propensity score matching. RESULTS: One hundred and six patients were placed in each group after propensity score matching. In the anakinra group, relative risk reduction for intensive care unit admission was 50% when compared to the tocilizumab group and the number needed to treat to avert an intensive care unit admission was 3 (95% CI, 2-5). In terms of mortality, a 52% relative risk reduction was observed with anakinra treatment and the number needed to treat to avert an intensive care unit admission was 8 (95% CI, 4-50). Significantly more patients were observed to receive glucocorticoids in the anakinra group. DISCUSSION: Anakinra administration in severe COVID-19 patients was significantly associated with better survival and greater clinical improvement compared to the tocilizumab administration in our study. Increased rate of glucocorticoid use in the anakinra group might have contributed to better outcomes.

RESUMEN

Introduction: Testicular torsion is a surgical emergency that results in testicular ischemia as a result of rotation of the spermatic cord around itself. Oxidative damage occurs in the testis and distant organs with the overproduction of free radicals and overexpression of proinflammatory cytokines by reperfusion after surgery. In this study, we aimed to investigate the effects of cerium oxide (CeO2), an antioxidant nanoparticle, on lung and kidney tissues in testicular torsion/detorsion (T/D) in rats. Materials and Methods: After ethics committee approval, 24 rats were equally (randomly) divided into 4 groups. Left inguinoscrotal incision was performed in the control (C) group. In group CeO2, 0.5 mg/kg CeO2 was given intraperitoneally 30 minutes before inguinoscrotal incision. In group T/D, unilateral testicular T/D was achieved by performing an inguinoscrotal incision and rotating the left testis 720° clockwise, remaining ischemic for 120 minutes, followed by 120 minutes of reperfusion. In group CeO2-T/D, 0.5 mg/kg CeO2 was given intraperitoneally 30 minutes before testicular T/D. At the end of the experiment, lung and kidney tissues were removed for histopathological and biochemical examinations. Results: Glomerular vacuolization (GV), tubular dilatation (TD), tubular cell degeneration and necrosis (TCDN), leukocyte infiltration (LI), and tubular cell spillage (TCS) in renal tissue were significantly different between groups (p = 0.012, p = 0.049, p < 0.003, p = 0.046, and p = 0.049, respectively). GV and TCDN were significantly decreased in group CeO2-T/D compared to group T/D (p = 0.042 and p = 0.029, respectively). Lung tissue neutrophil infiltration, alveolar thickening, and total lung injury score (TLIS) were significantly different between groups (p = 0.006, p = 0.001, and p = 0.002, respectively). Neutrophil infiltration and TLIS were significantly decreased in group CeO2-T/D compared to group T/D (p = 0.013 and p = 0.033, respectively). Lung and kidney tissue oxidative stress parameters were significantly different between groups (p < 0.05). Renal tissue glutathione-s-transferase (GST), catalase (CAT), and paraoxonase (PON) activities were significantly higher, and malondialdehyde (MDA) levels were significantly lower in group CeO2-T/D than in group T/D (p = 0.049, p = 0.012, p < 0.001, and p = 0.004, respectively). GST and PON activities were higher, and MDA levels were lower in group CeO2-T/D than in group T/D in the lung tissue (p = 0.002, p < 0.001, and p = 0.008, respectively). Discussion. In our study, cerium oxide was shown to reduce histopathological and oxidative damage in the lung and kidney tissue in a rat testis torsion/detorsion model.

RESUMEN

INTRODUCTION: Colchicine is an ancient agent with well-known anti-inflammatory effects and commonly used in treatment of hyperinflammatory conditions. It has been argued that colchicine could be an appropriate treatment option in COVID-19 to control hyperinflammatory response. Here in this study, we aimed to investigate the impact of colchicine on outcomes of COVID-19 in our inpatient cohort. METHODOLOGY: In this retrospective cohort study, hospitalized COVID-19 patients were investigated. Demographics, comorbidities, COVID-19 symptoms, laboratory findings on admission and discharge, baseline and seventh day oxygenation status, rates of mortality, intensive care unit admission, administration of other anti-inflammatory treatments and length of hospital stay were compared between patients who received standard of care medications and who received colchicine additionally. RESULTS: Three hundred and thirty-six patients were included in the study (171 standard of care, 165 standard of care plus colchicine). The median length of hospital stay in colchicine group was significantly shorter. Rates of admission to intensive care unit, anti-inflammatory treatment administration and mortality did not differentiate between standard of care and colchicine groups. However, reduced rates of mortality and ICU admission were observed in patients who received colchicine with a dose of 1 mg/day when compared to patients who received 0.5 mg/day. CONCLUSIONS: Our study demonstrated that COVID-19 patients who received colchicine in addition to standard of care had shorter hospital stay. Our results further support the use of colchicine in treatment of COVID-19, particularly with a dose of 1 mg/day.
