Hypertension which is part of the metabolic syndrome has frequently a family background. The authors investigated therefore indicators of insulin sensitivity by the method of a hyperinsulinaemic euglycaemic clamp in the offspring of hypertensive probands. In conjunction with the increased interest in the role of muscles in influencing insulin sensitivity the authors were also interested in serum amino acid levels. They examined a group of 15 healthy offspring of hypertonic subjects (PHT) and compared them with a group of 18 healthy volunteers without a family-history of hypertension. PHT had as compared with controls a higher systolic pressure (117 +/- 7.2 mm Hg vs. 106.1 +/- 11.7 mm Hg p < 0.01). In the clamp examination in PHT significantly lower indexes of tissue insulin sensitivity were recorded, SI (46.51 +/- 11.8% vs. 54.3 +/- 7.79%, p = 0.02) and ISI (6.6 +/- 3.99 vs. 9.88 +/- 5.05, p < 0.01). In the PHT group were, in addition to the different ratio of some branched chain amino acids and tyrosine, also relations between indicators of insulin sensitivity and arginine. It is thus obvious that signs of reduced insulin sensitivity are present in PHT already in the preclinical stage. Relations between the altered insulin sensitivity and arginine, the precursor of nitrogen oxide, apparent only in PHT could be a stimulus for seeking associations with endothelial damage described in insulin resistant conditions.

Erectile dysfunction (ED) is a highly prevalent disease associated with aging as well as with several risk factors including hypertension, heart disease, obesity, dyslipidemia, diabetes, hypogonadism, drugs-related, and pelvic surgery. Many of these factors are components of the metabolic syndrome, a multiplex risk factor for cardiovascular disease (CVD). ED shares common risk factors with CVD. Endothelial dysfunction seems to be the early underlying pathophysiology across both conditions. The efficacy, tolerability and cardiovascular safety of sildenafil has been evaluated in numerous large, randomized, doubleblind, placebo-controlled clinical studies in the broad population of men with ED including men with several co-morbid conditions. Sildenafil is effective in several specific patient populations including the difficult-to-treat subpopulations such as diabetes mellitus and after radical prostatectomy. It is associated with rapid onset of action--within 14 minutes for some men--and an extended duration of action for up to 12 hours. Sildenafil improves quality of life and satisfaction for treated men and is well tolerated with a favorable safety profile. New data suggest that sildenafil has beneficial effects in several chronic conditions. It has been approved for the treatment of idiopathic pulmonary hypertension. Numerous articles have suggested that it improves endothelial function and a possible role on premature ejaculation or treatment of lower urinary tract symptoms has been suggested.
