Insufficiency of vitamin K occurs in adults rarely. It is caused by the cessation of entering the intestinal bile necessary for the absorption of phyloquinones (with obstruction and compression of the biliary tract), as well as chronic intestinal diseases accompanied by a syndrome of insufficiency of absorption (see). It is also observed with an overdose of dicumarin. Vitamin K enters the body with food and is partially formed by the intestinal microflora.
Clinical picture: hemorrhagic syndrome (nosebleeds, gums, gastrointestinal, intra-cutaneous and subcutaneous hemorrhages).
The diagnosis is confirmed by the data of clinical observation (diseases that contribute to the emergence of vitamin K deficiency), as well as laboratory biochemical research: hypoprothrombinemia is characterized below 30-35%, deficiency of proconvertin, and also IX and X factors.
Treatment is carried out in a hospital with vitamin K (vikasol) under the control of the level of prothrombin and coagulogram.
