Chronic active Epstein-Barr virus infection (CAEBV) is common in Asian countries and characterized by recurrent or persistent infectious mononucleosis-like symptoms. Here, we describe a rare case of CAEBV-associated generalized myositis with extranodal NK/T-cell lymphoma, who initially presented with swelling and muscle soreness in the extremities and was diagnosed as polymyositis at the initial stage. CAEBV-associated generalized myositis is different from polymyositis and other types of myositis. Furthermore, it is prone to lymphoma with poor prognosis.

Ann Med

December 2025

Department of Hematology, Affiliated Hangzhou First People's Hospital, Westlake University, School of Medicine, Hangzhou, China.

Background: The management of high-risk acute myeloid leukaemia (AML) remains challenging, highlighting the need for innovative conditioning strategies beyond current regimens.

Methods: In the present single-arm study, a FACT regimen comprised of low-dose total body irradiation (TBI) with fludarabine, cytarabine and cyclophosphamide was employed to treat cytogenetically high-risk AML patients exhibiting pre-transplant active disease. This clinical trial is registered in the Chinese Clinical Trial Registry with the registration number ChiCTR2000035111.

The trend of an annual increase in the detection of new cases of osteoarthritis (OA) and an increase in the number of patients with chronic lower back pain (LBP) calls for the search for new drugs and pharmaconutraceuticals with anti-inflammatory and chondroprotective properties. In 2019, approaches to the treatment of pain in OA significantly changed. In international and Russian clinical guidelines (CG), pharmaconutraceutical chondroitin sulfate (CS) and glucosamine sulfate (GS) are recommended for OA of different localization as a basic therapy.

At the present stage, great progress has been achieved in understanding the mechanisms of the development of cerebral ischemia. This became possible due to the achievements of theoretical disciplines, in connection with which the general biological approach was formed in the study of pathogenesis of acute and chronic cerebrovascular disorders (CVD). The discovery of pathways of free radical oxidation in cerebral ischemia made it possible to substantiate and develop therapeutic strategies using drugs with antioxidant and neuroprotective activity.
