Maternal and Fetal Outcome in Pregnant Women With Critical COVID-19 Treated With Tocilizumab in a Tertiary Care Hospital in Dubai.

INTRODUCTION: Pregnancy, complicated by coronavirus disease 2019 (COVID-19), results in higher hospitalization and mortality rate. Pathogenesis of COVID-19 is similar to any other systemic inflammatory condition but results in a cytokine storm of higher magnitude causing severe acute respiratory distress syndrome and multiorgan failure. Tocilizumab, a humanized monoclonal antibody, targets soluble and membrane-bound IL-6 receptors and is used in the treatment of juvenile idiopathic arthritis, rheumatoid arthritis, and cytokine release syndrome. However, studies exploring its role in pregnancy are minimal. Hence, this study was done to study the effect of tocilizumab on maternal and fetal outcomes in critical COVID-19 pregnant women. METHODOLOGY: A retrospective study was conducted on 28 pregnant women with critical COVID-19 who received tocilizumab. Clinical status, chest x-ray, biochemical parameters, and fetal well-being were monitored and documented. The discharged patients were followed up through telemedicine. RESULT: On treatment with tocilizumab, improvement was seen in the number of zones and patterns of chest x-ray, along with 80% reduction in the c-reactive protein (CRP) levels. Based on the WHO clinical progression scale, 20 patients improved by the end of first week, and by the end of first month, 26 patients became asymptomatic. Two patients died during the course of the disease. No fetal adverse effects were noted. CONCLUSION: Based on the encouraging response and as tocilizumab did not impart any adverse effects on the pregnancy, tocilizumab may be administered as an adjuvant to critical COVID-19 pregnant women in their second and third trimesters.

A Cross-Sectional Study to Assess mRNA-COVID-19 Vaccine Safety among Indian Children (5-17 Years) Living in Saudi Arabia.

The objective of this study is to assess the frequency and severity of adverse events following immunization (AEFI) in Indian children aged 5-17 years who received the Pfizer-BioNTech mRNA COVID-19 vaccine, as well as to investigate for predictors of AEFI. To examine AEFI following the first and second doses of Pfizer's vaccine, semi-structured questionnaires were distributed as Google forms at Indian schools in Saudi Arabia. The 385 responses included 48.1% male and 51.9% female children, with 136 responses of children aged 5-11 years (group A) and 249 responses from children aged 12-17 years (group B). Overall, 84.4% of children had two shots. The frequency of AEFI was reported to be higher after the first dose than after the second (OR = 2.12, 95% CI = 1.57-2.86). The reported AEFIs included myalgia, rhinitis, local reaction with fever, a temperature of 102 °F or higher, and mild to moderate injection site reactions. While group B frequently reported multiple AEFIs, group A typically reported just one. Local reaction with low grade fever was more frequently reported in group B after the first dose (24.1%) and second dose (15.4%), while local reaction without low grade fever was most frequently observed in group A after the first (36.8%) and second dose (30%). Only prior COVID-19 infection (OR = 2.98, 95% CI = 1.44-6.2) was associated with AEFI after the second dose in the study sample, whereas male gender (OR = 1.71, 95% CI = 1.13-2.6) and prior COVID-19 infection (OR = 2.95, 95% CI = 1.38-6.3) were predictors of AEFI after the first dose. Non-serious myocarditis was reported by only one child. According to the analysis conducted, the Pfizer's mRNA COVID-19 vaccination was found to be safe in Indian children.

Role of laboratory biomarkers in assessing the severity of COVID-19 disease. A cross-sectional study.

BACKGROUND: Corona virus disease 2019 (Covid-19) has high infectivity and mortality rate. Covid-19 patients can suddenly deteriorate and develop life threatening complications. Hence, there is a need to identify laboratory biomarkers in order to categorize high risk patients. The main purpose of the study is to investigate the role and correlation of laboratory parameters such as total leucocyte count (TLC), absolute lymphocyte count, platelet count, C-Reactive Proteins (CRP), serum ferritin, serum lactate dehydrogenase (LDH), serum procalcitonin and D-dimer in severe and non-severe Covid-19 patients. METHODOLOGY: This retrospective cross-sectional study was conducted at Latifa Women and Child Hospital in the UAE after obtaining ethical committee clearance. Based on the symptoms and the criteria by National Institute of Health, USA, 109 patients were divided into three groups: Non-severe with 75, severe with 18 and critical with 16 patients. Laboratory data of these patients were assessed through the electronic medical records (SALAMA). Statistical analysis was done using Statistical Packages for Social Sciences (SPSS) version 25.0 (SPSS/PC; SPSS-25.0, Chicago, USA). Laboratory test profiles were expressed as mean (SD). Independent 't' test and ANOVA were used to study the significance of means. P value less than 0.05 was considered significant. RESULT: Males were more severely affected than females. Severe and critically ill Covid-19 patients had a significantly higher TLC, serum LDH, ferritin and CRP and lower absolute lymphocyte count. PCT and D-dimer were significantly elevated in critical group. CONCLUSION: Along with clinical presentation and radiological findings, biochemical parameter may also be considered as important predictors for assessing severity in covid-19 patients.

Effect of Hypovitaminosis D on Lipid Profile in Hypothyroid Patients in Saudi Arabia.

BACKGROUND: Hypothyroidism is believed to be associated with dyslipidemia and is considered a risk factor for the development of atherosclerotic cardiovascular diseases (ASCVD). Vitamin D, due to its steroid hormone action, retains cell function and controls the metabolism of lipids. Therefore, the present study was carried out to show the association of the risk factors of ASCVD and deficiency of thyroid hormones and vitamin D levels since no previous studies have been performed on Saudi patients before. Methodology. A retrospective cohort study was carried out on 400 hypothyroid patients. Medical records of those patients were followed up and were classified as normal and hypothyroid patients according to their thyroid-stimulating hormone levels. TSH, vitamin D, and lipid profiles were determined using the ELISA technique. RESULT: Total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels were significantly higher in hypothyroid patients than those in the normal group. We have found a significant correlation between TSH levels and the risk factors of ASCVD (total cholesterol, triglycerides, and LDL-C). Moreover, a significant correlation between vitamin D levels and the risk factors of ASCVD (total cholesterol, triglycerides, and LDL-C) has been found. In addition, there is a correlation between deficiency of Vit D and low-TSH levels (95% CI 1.092-4.05) indicating a higher risk for the development of ASCVD among those patients. CONCLUSION: Hypothyroid and vitamin D-deficient patients must be screened regularly at an early stage to predict and also to prevent cardiovascular diseases. Moreover, an adequate supply of vitamin D and TH should be given to those patients to prevent cardiovascular diseases at an early stage.

Significance of Total Protein, Albumin, Globulin, Serum Effusion Albumin Gradient and LDH in the Differential Diagnosis of Pleural Effusion Secondary to Tuberculosis and Cancer.

INTRODUCTION: Lung cancer and Pulmonary tuberculosis are two major public health problems associated with significant morbidity and mortality worldwide particularly in low and middle income countries like India. Wrong diagnosis of lung cancer cases as pulmonary tuberculosis in primary health care system delays the onset of anti-cancer chemotherapy as well as initiation of DOTS thus increasing complication and mortality rate in malignancy patients. In this context easy, cost effective diagnostic tool at primary level must be the priority and need of hour. AIM: To study and evaluate any significance of biochemical parameters (total protein, albumin, globulin, serum effusion albumin gradient, LDH) in serum and pleural effusion secondary to tuberculosis and lung cancer. MATERIALS AND METHODS: A case control study was carried out on patients attending OPD and IPD, Department of Pulmonary Medicine, RMCH. Hundred cases of Tuberculosis effusion, 50 cases of Malignant effusion and 100 age and sex matched apparently healthy controls were taken for correlation of biochemical parameters (total protein, albumin, globulin, serum effusion albumin gradient, LDH) and statistically evaluated to find any significance between tuberculosis, lung cancer and control group. Blood and pleural fluid samples were collected and then subjected to assessment of parameters (total protein, albumin, LDH) by using EM360 Autoanalyser and kits were supplied by Transasia diagnostics. Globulin and Serum Effusion Albumin Gradient (SEAG) was calculated mathematically. STATISTICAL ANALYSIS: Data is presented as mean ± SD. Comparison of serum and pleural fluid levels (of taken parameters) were done in TB, Lung Cancer and Control groups by ANOVA and students t-test. The p-value <0.05 were considered as statistically significant. RESULTS: We found serum-total protein, albumin, globulin to be significantly higher in TB group than lung cancer group but serum LDH was higher in lung cancer group (in all parameters p=<0.0001). Pleural Fluid-total protein, albumin, globulin was again significantly higher in TB group than lung cancer group and LDH was higher in lung cancer group (p=<0.0001). SEAG is also significantly higher in TB group than lung cancer group (p=<0.002). CONCLUSION: The results suggests early quantization of these parameters can differentiate pulmonary tuberculosis from lung cancer and thus can decrease the mortality rate of lung cancer cases though more extensive study with increased sample size may provide more insights.
