When it rains, it pours: Early treatment with tecovirimat of cardiac complications associated with monkeypox infection in a person with HIV and previously undiagnosed Lyme disease. A case report.

Cardiac involvement, such as myocarditis and pericarditis, can be a severe complication of monkeypox virus (mpox) infection and could be related to other co-infections with cardiac involvement. Tecovirimat is an antiviral specifically designed to inhibit smallpox infection diffusion and approved by the FDA for other Orthopoxvirus infections; its efficacy in mpox-infected patients is not well established. We present the case of a cardiac complication during mpox infection in a previously undiagnosed Lyme disease in a 42-year-old man living with HIV. Two days after the typical maculopapular rash, the patient reported a rise in body temperature up to 39 °C, chest pain without irradiation, and shortness of breath. We found an increase in troponin level, a slight reduction in ejection fraction, and grade 2 AV block (Mobitz 1 and 2) with frequent sinus pauses (the longest of 10.1 s). Given the suspicion of myopericarditis with cardiac conduction system involvement, the patient was admitted to the Intermediate Care Unit for continuous monitoring and further evaluation. Treatment included Ibuprofen 600 mg every 12 hours (bid) and colchicine 1 mg once daily for anti-inflammatory purposes. Concomitantly, treatment with tecovirimat was started at 600 mg bid for a total of 14 days. Cardiac MRI with gadolinium showed mild interstitial edema and pericardial enhancement. However, despite the clinical and laboratory resolution of the acute phase, bradycardia with episodes of AV block persisted at follow-up, suggesting the possibility of an additional etiology. Thus, the patient was investigated for Lyme disease because high-degree AV block is the most common presentation of Lyme carditis. Serological results evidenced a previous Borrelia burgdorferi senso latu. We decided to start treatment with doxycycline 100 mg every 12h, even pending the uncertainty of the role of a previous Lyme disease in determining the cardiac rhythm disturbances. At the evaluation on day 44, the patient was systemically well, and after cardiologist consultation, pace-maker implantation was not deemed indicated. This case underscores the importance of considering alternative causes of carditis when the clinical picture remains unclear or persists after the acute phase.

TAVR in patients with hip fracture and severe aortic stenosis: how and when?

Comorbidities are common in elderly patients with hip fracture and are associated with an increased mortality after surgery. Internal medicine/geriatric leaded multidisciplinary hip fracture teams may play a pivotal role in the clinical management of complex patients. Treatment strategy is particular relevant in patients with severe aortic stenosis that represent more than 5% of patients with hip fracture. These patients have a high in-hospital mortality and poor 1-year survival (less than 50%). Transcatheter aortic valve replacement (TAVR) may be an option in selected patients; however, the choice to treat and, in the case, the timing of valve replacement in relation to hip surgery is highly dependent on clinical conditions before trauma. In this paper, three different scenario of TAVR timing after hip fracture are reported.
