Abstract Since the outbreak of COVID-19 several studies conducted to identify predictive factors which are associated with prognosis of COVID-19. In this study we aimed to determine whether the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) could help the clinicians to predict intensive care unit (ICU) admission and mortality of COVID-19 patients. This retrospective cohort study involved examining the medical records of 311 Iranian COVID-19 patients from 22 July 2020 to 22 August 2020. All characteristic data and laboratory results were recorded. The receiver operating characteristic (ROC) curve was used to identify the predictive value of studied parameters for ICU admission and death. Comparison of data revealed that some factors were jointly higher in non-survivors and ICU admitted patients than survivors and non-ICU admitted patients, such as: age, hemoglobin (HB), NLR, derived neutrophil-to-lymphocyte ratio (dNLR), PLR, systemic inflammatory index (SII), lactate dehydrogenase (LDH), Respiratory diseases, ischemic heart disease (IHD). Multivariate logistic regression analysis showed that only hypertension (OR 3.18, P=0.02) is an independent risk factor of death in COVID-19 patients, and also PLR (OR 1.02, P=0.05), hypertension (OR 4.00, P=0.002) and IHD (OR 5.15, P=0.008) were independent risk factor of ICU admission in COVID-19 patients. This study revealed that the NLR, PLR, platelet-to-white blood Cell ratio (PWR), dNLR and SII are valuable factors for predicting ICU admission and mortality of COVID-19 patients.

Spectrum Disorders

Neuromyelitis optica spectrum disorder is a severe and disabling disease that manifests with severe relapses of optic neuritis, longitudinally extensive myelitis, and/or brainstem syndromes. The disease is complex and, although onset typically occurs in middle age, children and adolescents may be affected. The present study adds to the literature through detailed clinical data from 36 Brazilian patients with neuromyelitis optica spectrum disorder starting before age 21. This was a retrospective assessment of medical records from 14 specialized units in Brazil. The results showed that the course of neuromyelitis optica spectrum disorder was worse in patients with disease onset before the age of 12 years. Gender and ethnic background did not influence disability accumulation. Over a median period of 8 years, 14% of the patients who presented the initial symptoms of neuromyelitis optica spectrum disorder before the age of 21 years died. In conclusion, the present study adds to the reports from other authors examining the severity of early-onset neuromyelitis optica spectrum disorder.

A 12-year-old girl sought care for subacute onset of cramping back pain, along with paresthesias in her lower limbs up to the waistline, both hands, upper back, and chest, followed by rapidly progressive (over a few hours) painful vision loss affecting initially the right eye with subsequent involvement of the left eye. She underwent neuroophthalmologic evaluation and was diagnosed with bilateral optic neuritis. A positive Lhermitte sign was also present. The patient was tested for aquaporin-4-immunoglobulin G autoantibodies, which were positive in both serum and cerebrospinal fluid. A diagnosis of aquaporin-4-immunoglobulin G–positive neuromyelitis optica was made. The patient was treated with rituximab (anti-CD20 monoclonal antibody) and became episode-free, with no further accumulation of disability. The discovery of aquaporin-4-immunoglobulin G in 2004 has permitted the distinction of neuromyelitis optica spectrum disorder from other inflammatory central nervous system disorders. Aquaporin-4-immunoglobulin G represents a highly specific biomarker for neuromyelitis optica (almost 100% using molecular-based techniques), with sensitivity of approximately 80%. According to the most recent diagnostic criteria published in 2015, a diagnosis of neuromyelitis optica spectrum disorder can also be made for patients who are aquaporin-4-immunoglobulin G seronegative by any testing method, regardless of assay sensitivity, provided that more stringent clinical and radiologic requirements are met. Serial testing is recommended for these patients because late seroconversion has been described up to 4 years after the first episode.

Aim: We assessed the prognostic value of neutrophil-to-lymphocyte ratio (NLR) for all-cause mortality in patients with hypertrophic cardiomyopathy (HCM). Methods & results: A total of 354 HCM patients were enrolled. There were 44 all-cause mortality in total. Patients in the third tertile of NLR had the highest all-cause mortality rate of 5.2 per 100 person-years. Patients in tertile 3 had a significantly higher risk of all-cause mortality with adjusted hazard ratio of 2.4 (95% CI: 1.0–5.4; p = 0.040) when compared with that of patients in tertile 1. No significant interactions between NLR and other variables were observed during subgroup analysis. Conclusion: NLR was an independent risk factor for all-cause mortality in HCM patients.

Abstract Coronavirus disease 2019 (COVID-19) is an important and urgent threat to global health. Inflammation factors are important for COVID-19 mortality, and we aim to explore whether the baseline levels of procalcitonin (PCT), C-reaction protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) are associated with an increased risk of mortality in patients with COVID-19. A retrospective study was conducted and a total of 76 patients with confirmed COVID-19 were included between January 17, 2020 to March 2, 2020, of these cases, 17 patients were dead. After adjusting covariates, PCT (≥ 0.10 ng/mL) and CRP (≥ 52.14 mg/L) exhibited independent increasing risks of mortality were used hazard ratio (HR) of 52.68 (95% confidence interval [CI]: 1.77–1571.66) and 5.47 (95% CI: 1.04–28.72), respectively. However, NRL (≥ 3.59) was not found to be an independent risk factor for death in our study. Furthermore, the elevated PCT levels were still associated with increasing risk of mortality in the old age group (age ≥ 60 y), and in the critically severe and severe patients after adjustment for complications. Thu Baseline levels of PCT and CRP have been addressed as independent predictors of mortality in patients with COVID-19.

AbstractThis review highlights the most common presentations of demyelination of the central nervous system (CNS, termed acquired demyelinating syndrome) in children, the difficulty in determining whether the first episode represents a monophasic/transient illness or relapsing disease, and the potential underlying etiologies that must be considered, including multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and disorders associated with antibodies to myelin oligodendrocyte glycoprotein (MOG) antibodies. The initial clinical and magnetic resonance imaging (MRI) features, as well as those observed over time, are highlighted, emphasizing the distinct and overlapping features of each of these disorders.

Objective: According to metastatic renal cell carcinoma treatment protocol, after the use of tyrosine kinase inhibitors (TKI) has been achieved significant improvements for the treatment of metastatic renal cell carcinoma (mRCC). In this study, we aimed to investigate the effect of neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI) on survival in patients with mRCC treated with sunitinib or pazopanib. Material and Methods: Medical data for 38 patients with mRCC were reviewed retrospectively. NLR and PNI values were dichotomized based on receiver operating characteristic (ROC) curve analysis (cut-off values: 3 and 46, respectively). Univariate and multivariate analyses were performed to identify prognostic factors for progression free survival (PFS) and overall survival (OS) using a Cox proportional hazards model. Results: Median PFS and OS were 12 and 27 months, respectively. Median PFS was 10 months in patients with NLR ≥3 while 14 months in patients with NLR <3 (p: 0.008). Median OS was 18 months in patients with NLR ≥3 while 31 months in patients with NLR <3 (p: 0.003). In patients with PNI ≥ 46, PFS was 21 months and OS was 47 months whereas in patients with PNI < 46, PFS was 8 months and OS was 13 months (p values were <0.001, <0.001 respectively). In multivariate analysis, PNI was the independent risk factor for both PFS and OS, while NLR was the independent risk factor for OS only. Conclusion: In patients with mRCC that using sunitinib or pazopanib, NLR and PNI values can be used as easily accessible prognostic markers.
