The idiopathic form of the disease is characterized by an atypical clinical picture, the absence of complications except for allergic manifestations and the development of possible side effects after intravenous administration of drugs containing deoxycholic acid, used for transplant rejection. The course of amyloidosis is long, persistent, and gradually increasing; patients live from several months to 12–15 years, but there is practically no treatment. However, attention to this form of patients is much less than to others. And what the hell is not joking... From time to time, it begins to take a turn. The insidiousness of amyloid lies in the fact that there is no specific program in the immune system, unlike mucins, which are dealt with constantly and successfully, this gives hope. Therefore, it is noted in both children and the elderly, with extremely different diseases, the question arises - how does it manage to manifest itself without symptoms, but only exacerbating the course of other diseases in waves? Amyloids have been studied since the end of the 19th century. It has been found, for example, that it is present in sheep's milk. The American scientist Mayo proved the possibility of obtaining amyloid proteins by simply diluting cow's milk. Later, Finnish and French scientists isolated bacterial surface proteins, which turned out to be linear proteins with a molecular weight of 15 to 30 kilograms.
