Abstract
INTRODUCTION Human immunodeficiency virus (HIV) remains a worldwide disease with significant mortality and morbidity. There are a multitude of HIV-related kidney diseases including HIV-associated nephropathy (HIVAN) most prominently. The risk of developing HIVAN increases with decreasing CD4 count, higher viral load, and based on genetic factors. The mortality rate for those with HIVAN-end stage renal disease (ESRD) remains 2.5-3 times higher than ESRD patients without HIVAN. AREAS COVERED The epidemiology of HIVAN, particularly risk assessment, will be explored in this review. Further, the pathogenesis of HIVAN, from viral-specific renal expression to the role of genetics as well as characteristic renal pathology will be described. Diagnosis and management of HIVAN will be addressed, with an emphasis on various treatment strategies including medication, dialysis, and kidney transplantation. EXPERT OPINION HIVAN is associated with a high risk for progression to ESRD and increased mortality. The backbone of HIVAN therapy remains combined anti-retroviral therapy (cART), while adjunctive therapies including RAAS blockade and prednisone, should be considered. In those who progress to ESRD, dialysis remains the mainstay of management, though increasing evidence has demonstrated that kidney transplantation can be effective in those with controlled HIV disease.

Abstract
HIV-associated nephropathy (HIVAN) is a largely distinctive phenotype induced by HIV-1 infection and is the most recognized and detrimental kidney disease in HIV-infected patients. Host and viral characteristics have been implicated in the pathogenesis of HIVAN that may explain its exclusive predilection to patients of African descent. In untreated patients, the disorder is clinically manifested by an acute decline in kidney function, most often in conjunction with high-grade proteinuria and uncontrolled HIV-1 infection. Histologically, proliferating glomerular epithelial cells are the prominent feature of the disease. Data have evolved over the past decade suggesting that highly active antiretroviral therapy (HAART) can change the natural history of HIVAN, not only by preventing its development but also by halting its progression once developed. Consequently, with the widespread use of HAART, the prevalence of HIVAN is declining in Western countries. In contrast, the epidemiology of the disease is not well defined in the poorest areas in the world, which bear a disproportionate share of the HIV-1 epidemic's burden. Corticosteroids and inhibition of the renin-angiotensin axis are recommended as adjunctive agents in treating patients with established HIVAN and are potentially helpful in delaying the need for renal replacement therapy. However, the long-term value and potential risks of using corticosteroids in this population are unclear.

Abstract
With the introduction of highly active antiretroviral therapy, we have witnessed prolonged survival with the potential for normal life expectancy in HIV-infected individuals. With improved survival and increasing age, HIV-infected patients are increasingly likely to experience co-morbidities that affect the general population, including kidney disease. Although HIV-associated nephropathy, the most ominous kidney disease related to the direct effects of HIV, may be prevented and treated with antiretrovirals, kidney disease remains an important issue in this population. In addition to the common risk factors for kidney disease of diabetes mellitus and hypertension, HIV-infected individuals have a high prevalence of other risk factors, including hepatitis C, cigarette smoking and injection drug use. Furthermore, they have exposures unique to this population, including antiretrovirals and other medications. Therefore, the differential diagnosis is vast. Early identification (through efficient screening) and definitive diagnosis (by kidney biopsy when indicated) of kidney disease in HIV-infected individuals are critical to optimal management. Earlier interventions with disease-specific therapy, often with the help of a nephrologist, are likely to lead to better outcomes. In those with chronic kidney disease, interventions, such as aggressive blood pressure control with the use of ACE inhibitors or angiotensin receptor antagonists where tolerated, tight blood glucose control in those with diabetes, and avoidance of potentially nephrotoxic medications, can slow progression and prevent end-stage renal disease. Only with greater awareness of kidney-disease manifestations and their implications in this particularly vulnerable population will we be able to achieve success in confronting this growing problem.

Abstract
Approximately 10% of adult patients with human immunodeficiency virus (HIV) infection have HIV-associated nephropathy (HIVAN). This condition, a leading cause of renal failure, is characterized by damage to specific areas of the renal filtration system. It manifests with increased serum creatinine levels, overt proteinuria, and in some patients, end-stage renal disease (ESRD). The mortality rate for HIVAN-related ESRD is high-30% within the first year of onset. Most instances of HIVAN occur in patients of African descent. Although advances in defining the pathology have been made, the optimal treatment strategy remains unclear. Potential benefits of potent combination antiretroviral therapy, angiotensin-converting enzyme (ACE) inhibitors, and corticosteroids have been reported in small clinical trials and case reports. Cyclosporine is another option, but clinical experience with this agent in managing HIVAN is limited. Few conclusions can be drawn from the limited body of available evidence. Antiretroviral therapy, ACE inhibitors, and corticosteroids are possibly associated with reversal of serum creatinine level increases and proteinuria, but studies are necessary to further define the role of these agents in therapy. Close monitoring is advised when treating any patient with HIVAN.

Abstract
In 1984, physicians in New York and Miami reported HIV-infected adult patients with heavy proteinuria and rapid progression to end-stage renal disease. These patients showed large edematous kidneys with a combination of focal segmental glomerulosclerosis (FSGS) and tubulointerstitial lesions. This renal syndrome, named HIV-associated nephropathy (HIVAN), was found predominantly in African Americans. Subsequent studies confirmed the presence of HIVAN in children, who frequently develop nephrotic syndrome in association with FSGS and/or mesangial hyperplasia with microcystic tubular dilatation. Since then, substantial progress has been made in our understanding of the etiology and pathogenesis of HIVAN. This article reviews 20 years of research into the pathogenesis of HIVAN and discusses how these concepts could be applied to the treatment of children with HIVAN. HIV-1 infection plays a direct role in the pathogenesis of childhood HIVAN, at least partially by affecting the growth and differentiation of glomerular and tubular epithelial cells and enhancing the renal recruitment of infiltrating mononuclear cells and cytokines. An up-regulation of renal heparan sulfate proteoglycans seems to play a relevant role in this process, by increasing the recruitment of heparin-binding growth factors (i.e., FGF-2), chemokines, HIV-infected cells, and viral proteins (i.e., gp120, Tat). These changes enhance the infectivity of HIV-1 in the kidney and induce injury and proliferation of intrinsic renal cells. Highly active anti-retroviral therapy (HAART) appears to be the most promising treatment to prevent the progression of childhood HIVAN. Hopefully, in the near future, better education, prevention, and treatment programs will lead to the eradication of this fatal childhood disease.

Abstract
Initially described in 1984, human immunodeficiency virus-associated nephropathy (HIVAN) has now become a common disease within the HIV-seropositive population. It is a focal segmental glomerulosclerosis causing rapid deterioration of renal function. It is the most common cause of chronic renal disease in HIV patients and occurs almost exclusively in blacks. Through murine and human studies, it is now clear that HIVAN is caused by a direct effect of infection of renal cells by HIV-1 and that the virus actively replicates within renal cells. How the virus causes disease within cells is not yet understood, but there is evidence for factors within infected cells causing both proliferation and apoptosis. Steroids, angiotensin converting enzyme (ACE) inhibitors, and highly active antiretroviral therapy (HAART) have been used for the treatment of HIVAN, with HAART, in particular, showing a dramatic improvement in both the pathologic changes and clinical course of HIVAN.

Abstract
HIV-associated nephropathy (HIVAN) is the most common cause of renal failure in patients infected with type 1 human immunodeficiency virus (HIV-1). The renal prognosis for HIVAN is poor and is typically associated with rapid progression to renal death. We report a patient with biopsy-proven HIVAN who was successfully treated with corticosteroids and review the currently available evidence supporting the specific treatments of this condition. A 34-year-old African-American male with a 2-year history of uncomplicated HIV disease developed progressive azotemia despite treatment with highly active antiretroviral therapy (HAART). He was treated with an uncomplicated 4-month course of prednisone, which improved his serum creatinine from 2.9 to 1.9 mg/dl and decreased his degree of proteinuria from 8 to 2.1 g/day. Two years post-steroid treatment his renal function remains stable. Increasing evidence supports that both ACE inhibitors and HAART are effective in preventing and in some cases of reversing HIVAN induced renal failure. In selected patients who progress despite these measures, a limited course of corticosteroid may achieve long-standing disease remissions. In general, with adequate supervision, corticosteroid therapy appears to be well tolerated and has an acceptable side effect profile. Although persuasive in view of the abysmal natural history of HIVAN, the currently available studies are subject to major methodological limitations. Appropriate randomized controlled trials are urgently required in order to further examine the efficacy, optimal timing, and potential side effects of these treatments.

Abstract
HIV infection has reached endemic proportions in many African countries. In addition, HIV infection is a significant cause of renal dysfunction in the United States. HIV patients are at higher risk of developing hypertension at a younger age than the general population. Predisposing factors for developing hypertension include vasculitis in small, medium, and large vessels in the form of leukocytoclastic vasculitis, and aneurysms of the large vessels such as the carotid, femoral, and abdominal aorta with impairment of flow to the renal arteries. A syndrome of acquired glucocorticoid resistance has been described in patients with HIV with hypercortisolism and a lower affinity of the glucocorticoid receptors. The syndrome is characterized clinically by weakness, hypertension or hypotension, and skin pigmentation changes. Acute and chronic renal failure is often associated with HIV infection. The associated dysfunction in water and salt handling often induces hypertension. Finally, atherosclerosis has been described in young adults with HIV infection secondary to receiving highly active antiretroviral therapy.

Abstract
Overproduction of transforming growth factor-beta clearly underlies tissue fibrosis in numerous experimental and human diseases. Transforming growth factor-beta's powerful fibrogenic action results from simultaneous stimulation of matrix protein synthesis, inhibition of matrix degradation, and enhanced integrin expression that facilitates matrix assembly. In animals, overexpression of transforming growth factor-beta by intravenous injection, transient gene transfer, or transgene insertion has shown that the kidney is highly susceptible to rapid fibrosis. The same seems true in human disease, where excessive transforming growth factor-beta has been demonstrated in glomerulonephritis, diabetic nephropathy, and hypertensive glomerular injury. A possible explanation for the kidney's particular susceptibility to fibrosis may be the recent discovery of biologically complex interactions between the renin-angiotensin system and transforming growth factor-beta. Alterations in glomerular hemodynamics can activate both the renin-angiotensin system and transforming growth factor-beta. Components of the renin-angiotensin system act to further stimulate production of transforming growth factor-beta and plasminogen activator inhibitor leading to rapid matrix accumulation. In volume depletion, transforming growth factor-beta is released from juxtaglomerular cells and may act synergistically with angiotensin II to accentuate vasoconstriction and acute renal failure. Interaction of the renin-angiotensin system and transforming growth factor-beta has important clinical implications. The protective effect of inhibition of the renin-angiotensin system in experimental and human kidney diseases correlates closely with the suppression of transforming growth factor-beta production. This suggests that transforming growth factor-beta, in addition to blood pressure, should be a therapeutic target. Higher doses or different combinations of drugs that block the renin-angiotensin system or entirely new drug strategies may be needed to achieve a greater antifibrotic effect.

Abstract
Human immunodeficiency virus-associated nephropathy (HIVAN) is characterized by massive proteinuria with rapidly progressive renal failure. We report an adult with HIV infection who developed nephrotic-range proteinuria and acute renal failure requiring hemodialysis. Renal biopsy findings were consistent with HIVAN, exhibiting focal and segmental glomerulosclerosis with dilated microcystic tubules filled with pale eosinophilic material. Institution of corticosteroid therapy was followed by significant improvement in renal function and proteinuria. Corticosteroids were tapered, and the patient experienced worsening of his renal failure and proteinuria. A second course of corticosteroids was again associated with improved renal function. This and other reports suggest that corticosteroids may improve the clinical course of HIVAN.

Abstract
The pathogenesis of human immunodeficiency virus-associated nephropathy (HIVAN) is unknown, but it is characterized by aggressive glomerulosclerosis, tubulopathy, and interstitial inflammation. Currently, no therapy has been proven effective for HIVAN. Angiotensin II has been implicated in the pathogenesis of progressive renal disease in the absence of HIV infection, and treatment with captopril enhances renal survival in patients with diabetic glomerulosclerosis. Serum angiotensin-converting enzyme levels are elevated in patients with HIV infection. We therefore compared the course of 18 patients with biopsy-proven HIVAN (nine treated three times per day with captopril and nine not treated [controls]). The controls were matched to the study patients by age, race, gender, and level of serum creatinine concentration. Renal survival was measured from time of biopsy and treatment with captopril until onset of therapy for end-stage renal disease. Differences between the groups' survival were assessed by Kaplan-Meier and Cox regression analyses. Seven African-American men and two women were in the captopril-treated group, and eight African-American men and one woman were in the control group. No control patient died before the initiation of dialysis. There was no difference between initial mean serum creatinine concentration (3.4 +/- 0.7 mg/dL v 3.7 +/- 0.5 mg/dL), CD4 count (66 +/- 27/microL v 92 +/- 15/microL), or age (41.4 +/- 4.1 years v 36.4 +/- 2.6 years) in the study patients and controls, respectively, but the mean urinary protein to creatinine ratio was higher in the study patients. Renal survival was enhanced in the patients compared with the controls (mean renal survival, 156 +/- 71 days v 37 +/- 5 days, respectively; curves different; P < 0.002, Mantel-Cox log-rank test). Captopril and antiretroviral therapy were associated with enhanced renal survival in a Cox regression analysis, while age, level of serum creatinine, urinary protein to creatinine ratio, and CD4 count were not. These data suggest that treatment with captopril and antiretroviral therapy might be useful in delaying the rapidly progressive renal failure characterizing HIVAN. Captopril might exert its effects by reducing angiotensin II levels, or, alternatively, through decreasing renal tissue expression of growth factors and cytokines or by affecting HIV protease activity and therefore extent of productive renal infection. Such findings must be confirmed by randomized, double-blind, placebo-controlled trials.

Abstract
PURPOSE To determine if prednisone ameliorates the course of human immunodeficiency virus-associated nephropathy (HIV-AN). PATIENTS AND METHODS Twenty consecutive HIV-infected adults with biopsy-proven HIV-AN (n = 17) or clinical characteristics of HIV-AN (n = 3) with serum creatinine concentrations > 177 mumol/L (2 mg/dL) or proteinuria > 2.0 g/d or both were prospectively evaluated and treated with prednisone at a dose of 60 mg/d for 2 to 11 weeks, followed by a tapering course of prednisone over a 2- to 26-week period. Serum creatinine concentration, 24-hour protein excretion, serum albumin, and steroid-related adverse effects were assessed before and after treatment. RESULTS Nineteen patients had serum creatinine concentrations > 117 mumol/L (2 mg/dL). Two of them progressed to end stage renal disease (ESRD) in 4 to 5 weeks. In 17 patients serum creatinine levels decreased from 717 +/- 103 mumol/L (8.1 +/- mg/dL) (mean +/- SE) to 262 +/- 31 mumol/L (3.0 +/- 0.4 mg/dL) (P < 0.001). Five patients relapsed after prednisone was discontinued and were retreated. In these 5 the serum creatinine declined from 728 +/- 107 mumol/L (8.2 +/- 1.2 mg/dL) to 344 +/- 47 mumol/L (3.9 +/- 0.5 mg/dL) (P < 0.01) in response to the second course of prednisone. Twelve of 13 tested patients showed a reduction in 24-hour urinary protein excretion with an average decrement from 9.1 +/- 1.8 g/d to 3.2 +/- 0.6 g/d (P < 0.005). Serum albumin increased from 24.4 +/- 3.6 g/L to 29.3 +/- 2.6 g/L (P = NS) in the 11 patients with paired 24-hour urine collections for whom pre- and post-treatment determinations were available. In one non-azotemic patient with nephrotic syndrome, protein excretion declined from 15.2 to 2.2 g/day and the serum albumin increased from 4.0 g/L to 31.0 g/L. The 20 patients have been followed for a median of 44 weeks (range 8 to 107). Eight ultimately required maintenance dialysis. Eleven died from complications of HIV disease 14 to 107 weeks after institution of prednisone; none was receiving prednisone at the time of death. Seven are alive and free from ESRD a median of 25 weeks (range 8 to 81) from the initiation of prednisone therapy. Six patients developed a total of seven serious infections while receiving prednisone, including Mycobacterium avium-complex infection in 2 and CMV retinitis in 3. CONCLUSION Prednisone improves serum creatinine and proteinuria in a substantial proportion of adults with HIV-AN. Corticosteroid-related side effects are not prohibitive. A prospective, randomized controlled trial is required to confirm these preliminary results.
