Urinary titin reflects the severity of walking ability, muscle strength, and muscle and cardiac damage in patients with Becker muscular dystrophy.

Background: Becker muscular dystrophy (BMD) is a dystrophinopathy caused by a pathological variant of the DMD gene. Urinary titin, a degradation product of the giant protein titin present in muscle sarcomeres, has been used as a biomarker to reflect muscle degradation in Duchenne muscular dystrophy, a more severe dystrophinopathy. However, the clinical significance of urinary titin levels in BMD remains unclear.

Efficacy and Tolerability of Ivabradine for Cardiomyopathy in Patients with Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is an intractable X-linked myopathy caused by dystrophin gene mutations. Patients with DMD suffer from progressive muscle weakness, inevitable cardiomyopathy, increased heart rate (HR), and decreased blood pressure (BP). The aim of this study was to clarify the efficacy and tolerability of ivabradine treatment for DMD cardiomyopathy.

Deep Vein Thrombosis in Severe Motor and Intellectual Disabilities Patients and Its Treatment by Anticoagulants of Warfarin Versus Edoxaban.

: Patients with severe motor and intellectual disabilities (SMID) often develop complications, including paralysis of the extremities due to abnormal muscular tonicity. Furthermore, the incidence of sudden death, which may be caused by pulmonary thromboembolism (PTE), is approximately 4.2%.

Multicenter, Open-Label, Randomized Controlled Trial of Warfarin and Edoxaban Tosilate Hydrate for the Treatment of Deep Vein Thrombosis in Persons with Severe Motor Intellectual Disabilities.

Sudden death in patients with severe motor and intellectual disabilities (SMID) is sometimes caused in part by pulmonary thromboembolism (PTE), and deep venous thrombosis (DVT) has drawn attention as a possible embolic source. Warfarin, which is a conventional therapeutic agent, is not easy to control appropriately, and daily management can be especially difficult in SMID patients. On the other hand, edoxaban tosilate hydrate, which has been newly approved for insurance coverage for the treatment of DVT, is not listed in the Guidelines for the Diagnosis, Treatment and Prevention of Pulmonary Thromboembolism and Deep Vein Thrombosis (DVT-PTE guidelines).
