Of their article, “Lyme-Associated Pericarditis: A Case Report and Literature Review,” Ameer and colleagues describe an 18-year-old man who developed pericarditis attributable to Lyme disease.1

The affected person who had a medical historical past of bronchial asthma, irritable bowel syndrome, and obsessive-compulsive dysfunction offered to the emergency division with complaints of chest ache.

The ache was intense – 8 on a scale of 10 and situated within the heart of his chest. The ache woke him up from sleep and was related to shortness of breath and palpitations.

The affected person’s EKG findings have been in keeping with pericarditis. And though testing for Lyme disease was destructive, the person was recognized with Lyme-induced pericarditis.

Pericarditis is swelling and irritation of the skinny, saclike tissue surrounding the center.2

His coronary heart palpitations and shortness of breath resolved fully and his chest ache improved following remedy with ibuprofen, colchicine and intravenous ceftriaxone.

“In sufferers with signs suggestive of Lyme pericarditis, empiric remedy must be administered instantly, even earlier than Lyme serology is processed,” the authors state.
