Case Report: Dilated cardiomyopathy with biventricular thrombus secondary to impaired coagulation in a patient with HIV.

Human immunodeficiency virus (HIV) infection is a known hypercoagulable state with venous thromboembolism with a high mortality rate compared to the general population. The homeostatic balance in HIV infected patients improves with treatment compared to those who are not.  A decreased hypercoagulable state noted by low levels of Von Willebrand factor, factor VIII and d-dimer levels along with higher protein C and S activity in patients on treatment suggests that hypercoagulable state is partially correctable with highly active antiretroviral therapy.

Co-infection with Influenza A and COVID-19.

Unlabelled: COVID-19, also called severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan, China. It has caused significant morbidity and mortality worldwide and has been declared a global pandemic by the WHO. Influenza occurs mainly during the winter, with the burden of disease determined by several factors, including the effectiveness of the vaccine that season, the characteristics of the circulating viruses, and how long the season lasts.

Association of Autoimmune Hashimoto's Thyroiditis with Systemic Lupus Erythematosis.

SLE (systemic lupus erythematosus) can be associated with other autoimmune disorders with overlapping clinical symptoms. We present a case of a 22-year-old male with recurring exertional dyspnea, chest pain, dry cough and chills, which on further testing revealed large pericardial effusion and bilateral pleural effusions along with laboratory abnormalities consistent with a diagnosis of overlap of SLE with serositis and Hashimoto's thyroiditis. SLE patients with underlying hypothyroidism are slow to respond to standard therapy unless the underlying hypothyroidism is adequately treated.
