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.
