ABSTRACT

Background COVID-19-related pulmonary complications have been explored extensively in the recent past. There is also a significant amount of literature on the neurological manifestations of COVID-19. However, there exists an unmet need to assess the impact of COVID-19 on patients with cerebrovascular diseases and its role in affecting mortality in such patients. Methods In this cross-sectional study, we analyzed 401,318 hospitalized patients with cerebrovascular diseases using the discharge data from the National Inpatient Sample 2020 to assess the association of COVID-19 with multiple clinical conditions, along with additional factors, such as length of stay in the hospital, total charges incurred, region and type of hospital, and primary insurance/payer in the United States of America. We used a multivariable logistic regression model to predict factors relating to mortality in such patients. Results The mortality during hospitalization in patients with cerebrovascular disease who were also diagnosed with COVID-19 was significantly higher than the patients without COVID-19 (22.50% vs 5.44%, p-value <0.0001). COVID-19 independently increased the odds of death significantly in patients with cerebrovascular diseases (adjusted OR = 4.81, p-value <0.0001). Other statistically and clinically significant factors that contributed to increased odds of mortality in such patients were comorbidities such as moderate/severe liver disease, myocardial infarction, congestive heart failure, and complications such as the development of a saddle pulmonary embolus. Conclusion COVID-19 was associated with higher mortality in patients with cerebrovascular diseases. It also significantly increased the duration of hospital stay and odds of mortality in such patients.

ABSTRACT

Background and aims The prevalence of vitamin B12 deficiency is found to coexist in hypothyroid patients, causing the persistence of symptoms concomitant to both diseases even on adequate thyroxine supplementation. Primary objective To study vitamin B12 levels in patients with hypothyroidism. Secondary objective To study the clinical profile of patients with hypothyroidism with special reference to anemia, and to study the association between vitamin B12 deficiency with anti-thyroid peroxidase (anti-TPO) antibodies and anti-thyroglobulin (anti-Tg) antibodies in patients with hypothyroidism. Methods and results A single-centric cross-sectional study was carried out over a period of one year. Among 100 hypothyroid patients, 68% were found to be vitamin B12 deficient, among whom 73.5% were females. Of patients with raised anti-TPO antibodies, 78.6% had vitamin B12 deficiency (p = 0.01), while 78% of patients with raised anti-Tg antibodies were vitamin B12 deficient (p = 0.07). The Pearson correlation coefficient (r) of vitamin B12 with anti-TPO and anti-Tg antibodies was -0.302 (p = 0.002) and -0.253 (p = 0.011), respectively. Conclusion There is a predilection of hypothyroid patients toward developing anemia, with vitamin B12 deficiency as a major etiology. This finding can be correlated with the hematopoietic action of thyroid-stimulating hormones as well as autoimmune thyroid disease predisposing to pernicious anemia.

ABSTRACT

INTRODUCTION: Prevalence of vitamin B12 deficiency is occasionally found to be coexisting in patients with hypothyroidism causing persistence of symptoms concomitant to both diseases even on adequate thyroxine supplementation. MATERIALS: A single-centric non-interventional cross sectional study was carried over a period of 1 year. 100 hypothyroid patients were evaluated for prevalence of anemia, and investigated for the etiology. Serum Vitamin B12 was obtained and an association was studied between Vitamin B12 and anti TPO and anti Thyroglobulin antibodies. Here, vitamin B12 deficiency was defined as <160 pg/mL. RESULT: Among 100 hypothyroid patients, 31% were males and 69% were females. The mean age of patients was 36.09±12.864 years. 68% patients were found to be Vitamin B12 deficient, and 73.5% of this deficient population were females. 78.6% patients with raised Anti TPO antibodies had vitamin B12 deficiency (p-value = 0.01), while 78% patients with raised Anti Thyroglobulin antibodies were vitamin B12 deficient (p-value = 0.07). The Pearson correlation coefficient (r) was -0.302 (p = 0.002) and -0.253 (p = 0.011) between Vitamin B12 anti anti TPO and anti Thyroglobulin antibodies respectively, thus showing a negative correlation between both. CONCLUSION: Thyroid hormones affect erythropoiesis, thus causing anemia in a deficient condition. In iodine sufficient areas, most common cause of hypothyroidism is autoimmune, predisposing individuals to other autoimmune diseases, one being pernicious anemia. In the studied anemic hypothyroid population, Vitamin B12 deficiency was found correlated with raised levels of serum anti-TPO and anti-Thyroglobulin antibodies. Supplementation of B12 may alleviate hypothyroid symptoms, thus making itself a novel addition in the routine hypothyroid prescription. References Aon M, Taha S, Mahfouz K, et al.

ABSTRACT

BACKGROUND AND OBJECTIVES: The Coronavirus disease 2019 (COVID-19) pandemic has posed an unprecedented challenge to the public healthcare system worldwide like none before, producing far-reaching global economic, humanitarian, and social crises. It is estimated to have affected more than 1.8 million people worldwide. India has faced two phases of the pandemic, being the country with 2nd most number of deaths with varying mortality patterns across the two waves. In this study, we compare the patterns of mortality between the two phases of pandemics in association with COVID-19 and non-COVID-19 deaths. MATERIALS AND METHODS: A retrospective observational study at a tertiary care center in Central India was carried out. Demographic patterns of mortality have been studied in each of the groups, and a comparative analysis was done between COVID-19 and non-COVID-19 mortality patterns in each phase of the study, that is, from 20th March 2020 to 19th September 2020 and from 20th September 2020 to May 2021, as well as between the two phases. RESULTS: The case fatality rate of COVID-19 positive patients in the second phase of the study was 22.04%, whereas the those of non-COVID-19 patients in the second phase were found to be 15.95%. A maximum number of COVID-19 positive deaths during the first wave of the pandemic occurred in September 2020 and during the second wave in April 2021. In the first phase of the study, 69.6% of patients who died were males, and 30.3% were females, whereas in the second phase among COVID-19 positive subjects, 65% deaths were among males, and 35% deaths were among females. COVID-19 positive mortality in the second phase showed, 26.53% to be hypertensive, while 13.8% were diabetic. CONCLUSION: It was found that most of the deaths in both phases of COVID-19 amongst COVID-19 positive patients and non-COVID patients were amongst the elderly population (>60 years) with male predominance. Most deaths in both populations occurred during the first 3 days of admission whereas it was relatively less in the second phase. Noncommunicable diseases like systemic hypertension, and DM had a significant influence on all-cause mortality and morbidity in both COVID-19 positive and non-COVID-19 patients in the first and second waves of COVID-19. Noncommunicable diseases thus played a major role in mortality among both the populations under study.
