Occult endocrine dysfunction in patients of cerebrovascular accident

Abstract

Background: Cerebrovascular disorders are common conditions leading to significant morbidity and mortality in the population. Occult endocrine disorders also contribute to the morbidity and we studied the prevalence of endocrine dysfunction in patients of cerebrovascular accident (CVA). Materials and Methods: We evaluated 30 patients of CVA (aged 18-75, admission within 72 h of symptoms and positive neuroimaging) in this prospective, observational study. All subjects were assessed clinically and biochemically for hormonal dysfunction at admission and for mortality at the end of 1 month. The patients were divided into two groups: Group 1 (infarct, n = 20) and Group 2 (hemorrhage, n = 10) and the data were analyzed with appropriate statistical tests using GraphPad Prism Software, version 6. Results: The study participants (24M:6F) had a mean age of 60.7 ± 11.4 years and body weight of 67.2 ± 11.4 kg. Fourteen out of 30 patients showed results consistent with an endocrine disorder, including sick euthyroid syndrome (SES) and central hypothyroidism (n = 10), secondary hypogonadism (n = 3), subclinical hypothyroidism (n = 1), and growth hormone (GH) deficiency in two patients. The endocrine conditions did not differ significantly between both the groups and nine out of 30 patients succumbed to their illness within 1 month. None of the hormonal parameters studied, could predict the 30 day mortality. Conclusion: Endocrine disorders are common in acute stage of CVA and commonest finding is a SES. Hormonal dysfunction did not differ based on the etiology of the CVA. Long-term follow-up is essential to understand the morbidity contributed by the hormonal alterations.
