Angiotensin in progressive renal diseases: theory and practice.
Experimental studies indicate that Angll is involved in the process of tissue destruction in chronic renal diseases. This notion has been verified in a number of small-to large-scale clinical studies using angiotensin (ANG) I converting enzyme inhibitors (ACEI). Although the repertoire of the pathophysiologic cascade underlying the progressive destruction of renal tissue has continued to expand over recent years, from proteinuria and physical forces to growth factors and metalloproteinase disregulations, studies now suggest that Angll is involved in many, if not all, of these processes. Because these expanded pathophysiologic potentials of Angll are based primarily on observations in vitro, their significance in vivo, and in humans in particular, needs to be established. Recent studies in animals and humans indicate that the role of Angll in renal tissue destruction is subject to the modulation of multiple environmental and genetic factors, such as dietary habit and ACE genotype. Further delineation of the role of Angll in this respect for specific renal diseases and patients will enable us to design an efficient therapeutic intervention for this otherwise most complex problem of today's nephrology.
