Abstract
Summary. Fibrinogen and collagen are the most important intercellular matrix proteins that directly effect on the differentiation of mesenchymal stem cells and osteogenesis. In addition, there are non-classical cases of this syndrome that require indepth study of pathogenesis and optimal disease correction. We examined literature data by keywords in databases PubMed, UpToDate, BMJ. We presented a review of current scientific data and observation results of a rare clinical case in a patient with hypodysfibrinogenemia without hematomesenchymal dysplasia with manifestations of aseptic necrosis of femoral heads. Conclusions: In general, various aspects of clinical and biochemical pathogenesis of fibrinogen abnormalities are currently studied in detail, but there are “white spots” in the study of sophisticated pathogenetic mechanisms at the molecular genetic level, namely protein catabolism, the reaction of separate synthesis of individual fibrinogen polypeptide chains in different tissues. Unresolved is the question of applicability of hemostatic corrective drugs in the absence of expressed thrombotic and hemorrhagic manifestations.
