The mean age of the 13 patients studied (9 women, 7 men) was 50.5 +/- 15.7 years. The disease was discovered on account of malaise (3 cases), behavioural disorders (4 cases), coma (3 cases), syncope (1 case) or right hemiparesis (1 case) or in the course of systematic examination (1 case). Eleven patients consulted for evaluation of hypoglycaemia and 2 for behavioural disorders. The history was characteristic, with malaise, loss of consciousness, severe neurological disorders (seizures, hemiparesis, hemiplegia or coma) and psychiatric disorders. These symptoms typically occurred in the morning before breakfast or between meals in 9 patients, and atypically at any point of time or after meals in 4 patients. Their hypoglycaemic nature was demonstrated by blood glucose determination in 11/13 cases and by response to ingestion of sugar in 12/13 cases. The mean period elapsed between the initial symptoms and the final diagnosis was 20.3 +/- 17.3 months. Inappropriate insulin secretion was elicited a.m. before breakfast, during Conn's diet or fasting test, or by calculating the blood insulin/glucose ratio or Turner's coefficient. Prior to surgery, the insulinoma was located by ultrasonography in 3/8 cases, by computerized tomography in 2/6 cases, by selective arteriography in 6/11 cases, and by phlebography with spleno-portal catheterization and staged sampling for insulin and C-peptide assays in 8/9 cases. Histological examination after surgery (11 cases) or necropsy (1 case) showed an adenoma without evidence of malignancy.

Based on two patients, we discuss the difficulties in diagnosing and managing primary aldosteronism in pregnancy, which derive from changes of the renin-angiotensin-aldosterone axis, from the uncertainty regarding blood pressure control along gestation and postpartum, and from the contraindication to the use of spironolactone. The first case is a 27 years old woman with a long standing refractory hypertension, a hemorrhagic stroke with left brachial hemiplegia and crural hemiparesia, two miscarriages, one stillbirth and one offspring with intrauterine growth retardation. Due to hypokalemia, a plasma aldosterone/renin activity ratio of 91, and a negative genetic screening for glucocorticoid remediable aldosteronism (GRA), a primary hyperaldosteronism with normal adrenals in CT scan was diagnosed, and good blood pressure control was attained with spironolactone. After two and a half years of normotension, a fifth pregnancy, managed with methyldopa evolved with satisfactory blood pressures, plasma potassium, fetal growth, uterine and umbilical arterial resistance indexes, and maternal endothelial function. At 37 1/2 weeks of pregnancy the patient delivered a healthy newborn weighing 2,960 g. Blood pressure rose during the 48 hours of postpartum in the absence of proteinuria and required i.v. hydralazine. The second patient is a 37 years old woman, with known refractory hypertension for 7 years, hypokalemia, plasma aldosterone/renin activity ratio greater than 40, normal adrenals in the CAT scan, and a negative genetic screening for GRA. She had normotensive pregnancies 5 and 3 years prior to the detection of hypertension, with hypertensive crisis in both postpartum periods, retrospectively considered as expressions of primary hyperaldosteronism.
