The coronavirus disease-2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 that has significant implications for the cardiovascular (CV) health of patients, although the respiratory disease is the predominant clinical sign of COVID-19. The presence of comorbidities such as hypertension, diabetes, and CV disease (CVD) increases the risk of morbidity and mortality due to CVD. Numerous patients with COVID-19 have basic CV ailments or develop severe heart injury due to the disease. Severe CV injury characterized by a huge rise of heart troponins is the most commonly seen effect on the heart. This happens in approximately 8%–12% of all patients. Direct myocardial injury because of viral association of cardiomyocytes and the effect of systemic inflammation appear to be the most common mechanisms responsible for the cardiac injury. The presence of preexisting CV disease and/or development of acute cardiac injury is associated with significantly worse outcomes in patients with COVID-19. Most of the current reports on COVID-19 have only briefly described CV manifestations in these patients. Given the significant adverse prognostic impact of cardiac involvement, further studies are needed on the incidence, mechanisms, clinical presentation, and outcomes of various CV manifestations in patients with COVID-19.

Background: In human immunodeficiency virus (HIV)-infected men, hypogonadism is the most common endocrinological disorder, and most cases of hypogonadism are secondary. The aim of this study was to find out the hormonal abnormalities in HIV-infected males and it's correlation with CD4 cell counts. Materials and Methods: One hundred HIV-infected male patients were evaluated in the Department of Medicine, Postgraduate Institute of Medical Education and Research and Dr. Ram Manohar Lohia Hospital, New Delhi, India, over a period of 12 months from September 2014 to August 2015 using history, physical examination, routine baseline investigations, and CD4 counts. Free testosterone, dehydroepiandrosterone sulfate (DHEAS), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin were measured using an overnight fasting sample. Patients were divided into three groups on the basis of CD4 counts (Group A: CD4 counts ≥350/mm3, Group B: CD4 counts between 200 and 349/mm3, and Group C: CD4 counts
