Celiac disease is one of the late complications of filarial infection, mostly seen in young and middle-aged people. It is believed that the lymphatic system is parasitized by adult filarial worms, and mechanical damage and allergic inflammation destroy the lymphatic vessels near the celiac pond, the lymphatic vessels in the general trunk of the lumbar intestine, and the walls and valves of the lymphatic vessels in the central part of the trunk, causing tortuous expansion of the walls of the lymphatic vessels and incomplete atresia of the valves, resulting in sluggish flow and retention of celiac lymphatic fluid, increased pressure in the vessels, and reflux and accumulation of lymphatic fluid in the distal ducts. The celiac lymphatic fluid eventually flows back into the kidney and ruptures to form a fistula that mixes with urine, forming celiac disease. The celiac lymphatic fluid, which contains a lot of nutrients, flows back into the kidney, enters the urinary tract through the rupture and is discharged from the body, causing the patient to suffer from malnutrition such as emaciation, anemia, low fat and low protein in the body, and even cachexia. Therefore, the treatment of celiac disease should be aimed at stopping celiac lymph from entering the urinary tract.
