A study of acute intermittent porphyria (AIP) in three female patients indicates the necessity of stressing that in cases of clinical and laboratory exacerbation of the disease in patients of reproductive age the possibility of the existence of pathological changes in the ovaries (polycystic ovary, anovulatory cycle) should be taken into consideration. By examination of patients' endocrinological status and on the basis of the experience of clinicians it can be concluded that in such cases of exacerbation of the disease, apart from conventional therapy with glucose, Panhematin, electrolyte correction and other symptomatic therapy, coexisting steroid deficiency should be corrected.
