[Takayasu-Onishi arteritis. Current etiopathogenetic aspects].
By Takayasu-Onishi's arteritis is meant an arteritic process with unknown aetiology which electively affects young women, seemingly of prevalently Asiatic stock. The disease concerns almost exclusively large elastic arteries and presents clinically with early preocclusive symptomatology followed, after a varying period, by a picture of obstructive angiopathy. Here, the most recent aetiopathogenetic findings are considered. The disease's predilection for the young female, together with certain clinical and experimental observations, suggest that a dysendocrine condition may have some pathogenetic responsibility, at least in a favourable sense; this responsibility is documented by the finding of high levels of oestrogenuria during the entire cycle in patients suffering from the disease. On the other hand, the angiopathy localization in the large elastic arteries and in certain segments of the aortic arch and epiaortic trunks means that the role of topographic moments whould not be underestimated. As regards infectious factors, the tubercular and streptococcic continue to be of great importance even today. Neither acts directly, however, but by way of an abnormal immunitary reaction which they seem able to trigger off. The infectious moment would thus appear to be related to the immunitary moment, and the latter would seem to play the part of perpetuating the pathological vascular involvement promoted by contact of the organism with the aetiological agent.
