The tubulointerstitial changes likely play an im portant role in the pathogenesis of the renal insufficiency and offer one explanation for the rapid decrease in renal function.

Both diffuse and global m esangial hyperplasia are identified in 25% of children with perinatal AIDS and protein- uria. The characteristic m icrocystic tubular dilations and the kidney enlargem ent of glom erulosclerosis associated with hum an im m un- odeficiency virus infection are absent in patients with diffuse m esan- gial hyperplasia. M icrograph of tubuloreticular cytoplasmic inclusions in glomerular endothelial cell. The latter are virtually diagnostic of nephropathy associated with HIV infection, provided systemic lupus erythematosus has been excluded. On immunofluo- rescent examination, findings in the glomeruli are nonspecific and similar in HIV-associated glom erulosclerosis and idiopathic focal segm ental glom erulosclerosis. These findings consist largely of immunoglobulin M and complement C3 deposited in a segmental granular pattern in the m esangium and capillaries. The sam e deposits also occur in 30% of patients with AIDS without renal disease [134,163,167]. FIGURE 7-33 HIV infection Possible pathogenic m echanism s of glom erulosclerosis associated with HIV infection. HIV-associated glomerulosclerosis is not the result of opportunistic infections. Indeed, the nephropathy m ay be the first m anifestation of H IV infection and often occurs in patients HIV in glomerular, tubular HIV in lymphocytes, before opportunistic infections develop. H IV-associated glom eru- epithelial cells monocytes losclerosis also is not an im m une-com plex-m ediated glom erulopathy because im m une deposits are generally absent. Three m echanism s have been proposed: direct injury of renal epithelial cells by infective H IV, although direct renal cell infection has not been dem onstrated Cytopathic HIV gene Cytokines, conclusively and systematically; injury by HIV gene products; or injury effects products growth factors by cytokines and growth factors released by infected lymphocytes and m onocytes system ically or intrarenally or released by renal cells after uptake of viral gene products. The variable susceptibility to Glomerular epithelial cell proliferation Tubular epithelial cell apoptosis and proliferation glom erulosclerosis also suggests that unique viral-host interactions m ay be necessary for expression of the nephropathy [132,156,166,173–175].

Thus, the optim al treatm ent is patients with acquired immunodeficiency syndrome, or both. Individual case reports and studies, often retrospective, involving reciprocal transplantation of kidneys between normal and on a sm all num ber of patients suggest a beneficial effect of mice transgenic of noninfectious HIV clearly show that the patho- m onotherapy with azidothym idine (AZT) on progression of renal genesis of HIV-glomerulosclerosis is intrinsic to the kidney .

These findings suggest that HIV gene rosis m ay be declining as a result of prophylaxis with AZT, proteins, rather than infective HIV, may induce the nephropathy trim ethoprim and sulfam ethoxazole, or other drugs. Using logistic either through direct effects on target cells or indirectly through the regression analysis, Kim m el and colleagues  dem onstrated an release of cytokines and growth factors. Steroids usually have been ineffective on proteinuria or progression of renal disease in adults and children. Recently, 20 adult patients with H IV-associated glom erulosclerosis or m esangial hyperplasia with proteinuria over 2 g/24 h and serum creatinine over 2 m g/dL were studied. These patients showed im pressive decreases in pro- teinuria and serum creatinine when given 60 m gd of prednisone for 2 to 6 weeks . Com plications of steroid therapy, however, were com m on. These include developm ent of new opportunistic infections, steroid psychosis, and gastrointestinal bleeding. The short-term im provem ent in renal function m ay correlate with an im provem ent in tubulointerstitial m ononuclear cell infiltration . In a single report of three children with perinatal AIDS, HIV-associated glomerulosclerosis, and normal creatinine clearance, cyclosporine induced a rem ission of the nephrotic syndrom e . This report has not been confirm ed, and the use of cyclosporine in adults with HIV-associated glomerulosclerosis has not been studied.

W eek Sim ilar outcom es prevailed in patients with proteinuria in the 9 nephrotic range and serum creatinine levels less than 2 m g/dL. The mechanism(s) of the renoprotective 7 effects of ACE inhibitors are unclear and m ay include hem odynam ic 6 effects, decreased expression of growth factors, or an effect on H IV 5 protease activity. Renal biopsy early in the course of the disease is important to define the renal lesion and guide therapeutic intervention.

W hereas these M aschio and coworkers; with permission cheap lisinopril 17.5mg. Hypertension may result from renal disease that reduces functioning nephrons discount 17.5mg lisinopril visa. Evidence shows a clear relationship between high blood pressure and end-stage renal disease lisinopril 17.5 mg sale. Blood pressure should be controlled to ≤130/85 mm Hg (<125/75 mm Hg) in patients with proteinuria rather than specific classes of m edication. Angiotensin-converting enzyme inhibitors work well to lower blood pressure and slow progression of renal failure. Sm ith M C, Dunn M J: H ypertension in renal parenchym al disease.

Pohl he major issues in approaching patients with renal artery steno- sis relate to the role of renal artery stenosis in the management Tof hypertension, ie, “renovascular hypertension,” and to the potential for vascular compromise of renal function, ie, “ischemic nephropathy. M uch discussion has focused on the pathophysiology of renovascular hyper- tension, the renin angiotensin system, diagnostic tests to detect pre- sumed renovascular hypertension, and the relative merits of surgical renal revascularization (SR), percutaneous transluminal renal angio- plasty (PTRA), and drug therapy in managing patients with renal artery stenosis and hypertension. H emodynamically significant renal artery stenosis, when bilateral or affecting the artery to a solitary func- tioning kidney, can also lead to a reduction in kidney function (ischemic nephropathy). This untoward observation may be reversed by interventive maneuvers, eg, surgical renal revascularization, PTRA, or renal artery stenting. The syndrome of “ischemic renal disease” or “ischemic nephropathy” now looms as an important clinical condi- tion and has attracted the fascination of nephrologists, vascular sur- geons, and interventional cardiologists and radiologists. The detection of renal artery stenosis in a patient with hyperten- sion usually evokes the assum ption that the hypertension is due to the renal artery stenosis. H owever, renal artery stenosis is not synony- m ous with “renovascular hypertension. The vast m ajority of patients with ASO -RAS who have hypertension have essential hypertension, not renovascular hyperten- sion. These hypertensive patients with ASO -RAS are rarely cured of their hypertension by interventive procedures that either bypass or 3 3. Thus, it is critical to distinguish chronic subcapsular hematoma, and unilateral ureteral obstruction between the anatom ic presence of renal artery stenosis, in may also be associated with hypertension that is relieved when which a stenotic lesion is present but not necessarily causing the affected kidney is removed. These clinical analogues of the hypertension, and the syndrom e of renovascular hypertension experimental Page kidney reflect the syndrome of renovascular in which significant arterial stenosis is present and sufficient to hypertension (RVHT), but without main renal artery stenosis. In the exam ples of RVH T without m ain renal artery stenosis. FIGURE 3-1 CLASSIFICATION OF RENAL Classification of renal artery disease. Two m ain types of renal arterial lesions form the ARTERY DISEASE anatom ic basis for renal artery stenosis. Atherosclerotic renal artery disease (ASO -RAD) is the most common cause of renal artery disease, accounting for 60% to 80% of all renal artery lesions. The fibrous dysplasias are the other m ajor category of renal artery disease, Disease Incidence, %* and as a group account for 20% to 40% of renal artery lesions. Arterial aneurysm and arteriovenous m alform ation are rarer types of renal artery disease. Atherosclerosis 60–80 Fibrous dysplasia 20–40 Medial (30%) Perimedial (5%) Intimal (5%) *Percent of renal artery lesions. Atherosclerotic renal artery disease is typi- cally associated with atherosclerotic changes of the abdominal aorta (see panel B). ASO- RAD predominantly affects men and women in the fifth to seventh decades of life but is uncommon in women under the age of 50. Anatomically, the majority of these patients demonstrate atherosclerotic plaques located in the proximal third of the main renal artery. In the majority of cases (70% to 80% ), the obstructing lesion is an aortic plaque invad- ing the renal artery ostium (ostial lesion). Twenty to 30 percent of patients with ASO- RAD demonstrate atherosclerotic narrowing 1 to 3 cm beyond the takeoff of the renal artery (nonostial lesion). Nonostial lesions are technically more amenable to percuta- neous transluminal renal angioplasty (PTRA) than ostial ASO-RAD lesions, which are technically difficult to dilate and have a high A B restenosis rate after PTRA. Renal artery stenting has gained wide acceptance for ostial FIGURE 3-2 lesions. Endovascular intervention for nonos- Angiographic exam ples of atherosclerotic renal artery disease (ASO -RAD).
