Kashin–Beck disease (KBD) is a chronic, endemic type of osteochondropathy that is prevalent in certain areas of Eastern Siberia, China, North Korea, and Tibet. The disease is named after the Russian physicians who first described it, Evgeny Kashin and Nikolay Beck.

Etiology

The exact cause of KBD is still unknown, but it is believed to be multifactorial. Factors such as selenium deficiency, contamination of grain by fungi, and high humic acid content in drinking water have been implicated. Selenium is an essential trace element that is necessary for the normal functioning of the human body, and its deficiency has been linked to KBD.

Clinical Features

KBD primarily affects the joints and the bones, leading to deformities and disabilities. The disease usually begins in childhood and progresses as the child grows. The most common symptoms include joint pain, limited range of motion, and growth retardation. In severe cases, the disease can lead to significant physical disability.

Diagnosis

The diagnosis of KBD is based on clinical features, radiographic findings, and the patient's history of living in an endemic area. Radiographic findings typically show changes in the growth plates and articular cartilage of the affected joints.

Treatment

There is currently no cure for KBD. Treatment is mainly supportive and aims to relieve symptoms and improve quality of life. This may include pain management, physical therapy, and in severe cases, surgery.

Prevention

Prevention strategies for KBD include improving the nutritional status of people living in endemic areas, particularly with regard to selenium intake, and improving the quality of drinking water.
