[Is salt sensitive hypertension an inflammatory disease? Role of lymphocytes and macrophages]

High blood pressure is a public health problem. This entity affects 43% of the mexican population and is considered a major risk factor for development of stroke, cardiac failure and chronic kidney disease. Hypertension prevalence has increased over the last decades, mainly because of high salt diet. There is evidence showing that salt-sensitive hypertension develops structural changes as tubular dilation, patchy interstitial fibrosis, osteopontin expression and lymphocytic/macrophage tubulointerstitial infiltrate that blunts urinary sodium excretion and therefore promotes HBP. It has been shown that this structural damage has an inflammatory origin and that immunosuppresant drugs down-regulates tissular injury and improves blood pressure control. In summary, this salt-sentitive hypertension data can be used in development of new and potent blood pressure drugs.
