It is well established that renin-angiotensin system suppressors prevent the development of new-onset albuminuria in naïf hypertensive patients and diminish its excretion, but we cannot forget the percentage of hypertensive patients who develop de novo albuminuria. Here, we applied multiple proteomic strategy with the purpose to elucidate specific molecular pathways involved in the pathogenesis and provide predictors and chronic organ damage indicators. Briefly, 1143 patients were followed up for a minimum period of 3 years. One hundred and twenty-nine hypertensive patients chronically renin-angiotensin system suppressed were recruited, classified in 3 different groups depending on their albuminuria levels (normoalbuminuria, de novo albuminuria, and sustained albuminuria), and investigated by multiple proteomic strategies. Our strategy allowed us to perform one of the deepest plasma proteomic analysis to date, which has shown 2 proteomic signatures: (1) with predictive value of de novo albuminuria and (2) sustained albuminuria indicator proteins. These proteins are involved in inflammation, immune as well as in the proteasome activation occurring in situations of endoplasmic reticulum stress. Furthermore, these results open the possibility of a future strategy based on anti-immune therapy to treat hypertension which could help to prevent the development of albuminuria and, hence, the progression of kidney damage.engSMURhttp://creativecommons.org/licenses/by-nc-nd/4.0/albuminuriacause of deathhypertensionimmune systemrenin–angiotensin systemAge FactorsAgedAlbuminuriaCohort StudiesDisease ProgressionFemaleHumansHypertensionIncidenceMaleMiddle AgedPredictive Value of TestsPrognosisProteomicsROC CurveRenal Insufficiency, ChronicRenin-Angiotensin SystemReproducibility of ResultsRetrospective StudiesRisk AssessmentSeverity of Illness IndexSex FactorsAttribution-NonCommercial-NoDerivatives 4.0 Internacional27217411681157-6610.1161/HYPERTENSIONAHA.116.074121524-4563Hypertension (Dallas, Tex. : 1979)open access
