[Hormonal contraceptives and high blood pressure (author's transl)]. 1979

J M Coderch Gimeno, and A Roca-Cusachs Coll

The aim of this report is to offer an explanation for the high incidence of arterial hypertension in women taken hormone contraceptives. The real incidence of this association has been considered in women initially having a normal blood pressure and in others who had high blood pressure before using these contraceptives. The estrogen and progestogen components in hormone contraceptives were analyzed individually in various studies. The most recent investigations seem to indicate that progestogen is the main cause of high blood pressure. Different mechanism that could link hormone contraceptives to high blood pressure were investigated. The renin-angiotensin-aldosterone axis involving the action of estrogens and progestogens on the renin substrate, plasma renin, angiotensin II and aldosterone were analyzed. Another possible mechanism could involve glucocorticoids, altering the metabolism of glucose, pyruvate, cholesterol, and triglycerides, Kidney disease involving renal function, microangiopathic anemia, and renal thromboembolism; hyperactivity of the sympathetic nervous system (noraepinephrine and dopamine-beta-hidroxylase blood levels); prostaglandins; genetic mechanism; and individual mechanism were all taken into consideration. Lastly the priorities of the different systems linking high blood pressure to hormone contraceptives and the relationships between them are analyzed.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D007606	Juxtaglomerular Apparatus	A complex of cells consisting of juxtaglomerular cells, extraglomerular mesangium lacis cells, the macula densa of the distal convoluted tubule, and granular epithelial peripolar cells. Juxtaglomerular cells are modified SMOOTH MUSCLE CELLS found in the walls of afferent glomerular arterioles and sometimes the efferent arterioles. Extraglomerular mesangium lacis cells are located in the angle between the afferent and efferent glomerular arterioles. Granular epithelial peripolar cells are located at the angle of reflection of the parietal to visceral angle of the renal corpuscle.	Apparatus, Juxtaglomerular
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011374	Progesterone	The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

D012083	Renin	A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D003276	Contraceptives, Oral	Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally estrogen or progesterone or both.

D004967	Estrogens	Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
