Surveys revealed increases in the prevalence of HIV-infected patients in the US end-stage renal disease (ESRD) program in the 1980s and early 1990s, with clustering in young black men 25 to 44 yr old. Since the availability of highly active antiretroviral therapy in 1996, the prognosis of HIV-infected patients has improved, and therapy has been shown to change the course of classic HIV-associated nephropathy. We used the United States Renal Data System database to determine if the incidence and prevalence of HIV-infected patients with renal disease has increased in the ESRD program, by means of principal diagnoses and comorbid AIDS-defining diagnoses.As the number of US patients living with AIDS increased 57% from 214,711 in 1995 to 337,017 in 2000, and the number of incident ESRD patients increased 29.9% from 72,827 to 94,602, the number of incident HIV-infected patients increased only by 3.5%, from 1133 to 1171. Over this time, the percentage of incident ESRD patients with HIV infection fell from 1.56% to 1.24%. Among black men 25 to 44 yr of age, HIV infection as a proportion of incident ESRD cases fell from 8.5% to 6.2% from 1995 to 2000. The incident rate per million of AIDS or HIV infection in black men aged 25 to 44 fell from 107 in 1995 to 78 per million in 2000. The incidence rate for HIV-infected women in the ESRD program rose 14% while it declined 7% in men. Almost 2000 HIV-infected women, or 28.8% of the population, have initiated therapy for ESRD with hemodialysis. The number of prevalent cases increased in absolute numbers 81.3% from 2687 to 4871 (0.90% to 1.16% of the ESRD program). One-year survival rates for HIV-infected incident ESRD patients increased from 53.1% to 67.1% from 1995 to 2000.Although these values may be underestimates because of underreporting due to confidentiality concerns and lack of biopsy confirmation, we conclude that although the prevalence of HIV infection is increasing in the US ESRD population, the increase as a proportion of the program is minimal and is due to better survival after development of renal failure. The incidence of HIV infection in the US ESRD program is stable. Highly active antiretroviral therapy may be responsible for the change in epidemiology of HIV infection in the US ESRD program.  相似文献

Background Controversy continues concerning the morbidity and mortality of HIV-infected ESRD patients on the two dialysis options. This article presents our experience with complications and survival rate among our HIV-infected ESRD patients on peritoneal dialysis and hemodialysis. We reviewed the literature on this subject. Methods The charts of seven and eight HIV-infected ESRD patients on peritoneal dialysis and hemodialysis respectively, between January 1989 and November 2004, were reviewed retrospectively for specific clinical and demographic data. Their survival was calculated using the Kaplan-Meier method. Results Total follow-up of HIV-infected PD and HD patients was 248.3 and 207 patient months, respectively. There was no significant difference in hospitalization rate between HIV-infected PD and HD patients (1.01 and 1.39 admission/year, respectively, P = NS). Survival of HIV-infected patients on PD at one, two and three years was 100, 83, and 50%, and for HD patients was 75, 33, and 33%, respectively. HIV-infected patients on HD had more prevalent advanced HIV disease. Two out of seven PD patients were on PD for more than five years and one of the HD patients was on that form of dialysis for more than nine years. Median survival of patients with advanced (Stage IV) AIDS (both HD and PD) was 15.1 months (range 1.6–17.3) while this value for non-advanced (Stage II, III) patients was 61.2 months (range 6.8–116.6). Conclusion Type of renal replacement therapy does not have a significant effect on the morbidity and mortality of HIV-infected ESRD patients. Survival is worse in patients with advanced HIV disease. Both dialysis options provide similar results in HIV patients; hence, the choice of dialysis modality should be based on patient’s preference and social conditions.  相似文献

The prevalence of human immuodeficiency virus (HIV)-infected patients with end stage renal disease (ESRD) is likely to increase and many of them will be on peritoneal dialysis as renal replacement therapy. Infectious complications are a major problem associated with peritoneal dialysis (PD). It has been speculated that the HIV-positive peritoneal dialysis population may develop peritonitis more frequently than other peritoneal dialysis patients. We present the complications and unexpected good response to medical management of PD-associated peritonitis in a young HIV-infected black male. He had two unusual and serious infections; the first was a polymicrobial peritonitis which predisposed the patient to an unusual infection caused by Corynebacteria JK for which he was successfully treated without catheter removal.

The percentage of dialysis centers that have reported dialyzing human immunodeficiency virus (HIV)-infected patients increased from 11% in 1985 to 37% in 2000. Being primary care physicians for the dialysis patients, nephrologists are frequently confronted with the management of HIV-infected dialysis patients especially in urban centers. The aims of the present review are to discuss issues that are unique to HIV infection and end-stage renal disease, and to provide dialysis caretakers with sufficient information to help them optimize care and improve outcomes of these patients. Issues related to the choice of renal replacement therapy, vascular access, management of anemia, vaccination, and antiretroviral therapies are discussed in detail.  相似文献

The rise in the number of patients with HIV-associated nephropathy and HIV-infection with end-stage renal disease (HIV+ ESRD) continues to be a substantial concern for the ESRD program. In order to assess the impact of highly active antiretroviral therapy (HAART) on the progression of patients with AIDS to the development of ESRD and to project the prevalence of HIV+ ESRD through 2020, a mathematical model of the dynamics of HIV+ infection in the ESRD population was developed. Epidemiologic data on AIDS and HIV+ ESRD among black individuals in the United States were obtained since 1991 from the Centers for Disease Control and Prevention and US Renal Data System, respectively. The model was constructed to predict the prevalence of HIV+ ESRD incorporating the current rate of growth in AIDS prevalence. Two possible trends were considered: linear AIDS growth and exponential AIDS growth. The likely effectiveness of HAART in slowing progression to HIV+ ESRD was estimated from the best fit of the model to the data after 1995, when HAART was introduced. The model was then used to evaluate recent data and to project the prevalence of HIV+ ESRD through 2020. The model suggested that HAART has reduced the rate of progression from AIDS to HIV+ ESRD by 38%. The model projected an increase in HIV+ ESRD prevalence in the future as a result of the increase in the AIDS population among black individuals. This increase was predicted even assuming a 95% reduction in the progression from AIDS to HIV+ ESRD. Despite the potential benefit of HAART, the prevalence of HIV+ ESRD in the United States is expected to rise in the future as a result of the expansion of the AIDS population among black individuals. It is concluded that prevention of progression to ESRD should focus on early antiretroviral treatment of HIV-infected patients who have evidence of HIV-associated nephropathy.  相似文献

Introduction

The prognosis of HIV infection has improved dramatically in patients with end-stage renal disease (ESRD). Thus, HIV infection is no longer an absolute contraindication for renal transplantation.

Methods

A cross-sectional study was performed to analyze the characteristics of HIV patients receiving renal replacement therapy (RRT) in September 2011, using data from the Registry of Renal Patients in Andalusia. A retrospective cohort study was also carried out, analyzing patients receiving kidney transplants in the era of highly active antiretroviral therapy.

Results

In Andalusia in September 2011, 8744 patients were on RRT; of these, 48 had HIV infection (prevalence 0.54%). The RRT modality was very different between HIV-negative and HIV-positive patients: renal transplantation 49.2% and 16.7%, hemodialysis 46.8% and 81.3%, and peritoneal dialysis 4% and 2%, respectively. The most frequent ESRD etiology was glomerulonephritis (37.5%). Twenty-seven (56.3%) had hepatitis C coinfection. Only three patients (7.5%) were on the waiting list for renal transplantation. From 2001 to September 2011, 10 HIV-infected patients received a renal transplantation (median follow-up 40.5 months). The initial immunosuppressive treatment included tacrolimus and mycophenolate without induction therapy. Only two patients presented acute rejection, both borderline and corticosensitive. All remain alive and the graft survival was 100% in the first and third years posttransplant. We compared demographic and comorbidity variables between patients transplanted or included on the waiting list (n = 12) and patients excluded and never transplanted (n = 36). We found differences only in the ESRD etiology (higher incidence of glomerulonephritis in excluded patients).

Conclusions

Renal transplantation is safe in correctly selected HIV-infected patients. The number of patients on the waiting list is very small. This may reflect the high comorbidity but it is also possible that these patients are still not being assessed systematically for transplant in all centers.  相似文献

For various ethnic and socioeconomic reasons the pattern of renal disease in the inner city displays distinctive features. Hypertension is frequent, often intractable, and generally conditioned by salt sensitivity and a high sodium intake. Chronic hypertensive nephrosclerosis, found predominantly in African Americans, comprises marked cardiomegaly, renal shrinkage, and hypertensive retinopathy. It has been overdiagnosed in the past, but actually accounts for less than 20% of end-stage renal disease (ESRD) in African Americans. Malignant hypertension, less frequent nowadays, may cause renal shutdown, which is reversible in a few cases; the heart and kidneys are often of normal size. Idiopathic focal segmental glomerulosclerosis is the most common cause of the primary nephrotic syndrome in blacks, but its incidence has also been rising in whites and Hispanics; it does not respond well to treatment, and almost one half of the patients develop ESRD within 10 years. Systemic lupus erythematosus is also more common in African Americans, in whom the severe proliferative forms of lupus nephritis pursue a more virulent course: one half of such patients develop ESRD in 5 years. Cocaine, the use of which has assumed epidemic proportions, may cause accelerated hypertension, acute renal failure from rhabdomyolysis, and progression of preexisting renal disease. Heroin nephropathy has all but disappeared and has been replaced by human immunodeficiency virus (HIV) nephropathy. The prognosis of HIV-infected patients maintained by dialysis has greatly improved. Sickle glomerulopathy, consisting of mesangial expansion, basement membrane duplication, and the absence of immune deposits, may cause the nephrotic syndrome in 4% of patients with severe sickle cell anemia, heralding death within 2 years in one half of patients and ESRD in two thirds; survival has not improved with dialysis. Diabetes is now the most common cause of ESRD. Familial aggregation of ESRD is frequently encountered. Interventions useful in the general population, such as vascular bypass procedures, should be undertaken with great caution and restraint in dialysis patients.  相似文献

BACKGROUND: The Centers for Disease Control and Prevention (CDC) recommends hepatitis B virus (HBV) immunization for all hemodialysis (HD) patients because they are at high risk of infection. Several studies have shown that the development of protective antibody titers after HBV vaccination is much lower in HD patients. We hypothesized that human immunodeficiency virus (HIV) infection in patients with end-stage renal disease (ESRD) would further impair the immune response to hepatitis B vaccination. METHODS: We performed a retrospective cohort study of patients undergoing long-term hemodialysis from 1990 to 2002 at the United States-based dialysis facilities of Gambro Corporation, North America. The response rate defined as an increase in anti-HBs levels >/=10 mIU/L after a month of the third dose of HBV vaccination was determined in HIV-infected and a randomly selected group of ESRD patients. The demographic information, laboratory data, and hepatitis B surface antibody (anti-HBs) titers were recorded from the Gambro Corporation database on these patients. RESULTS: Of the 347 adult HIV ESRD patients, 116 received three doses of recombinant hepatitis B vaccination. Seventy percent were male, and the majority (86%) were black. Of the 116 patients who received three doses of HBV vaccination, 62 (53.4%) developed protective antibody titers. This was comparable to the response rate of 50.4% in the randomly selected 220 non-HIV hemodialysis patients. Among HIV ESRD patients, the mean hemoglobin (Hgb) was higher in patients who developed protective antibody titers (Hgb 11.61 +/- 2 vs. 10.55 +/- 1.86, P value <0.01). On multivariate logistic regression analysis, higher Hgb was associated with protective antibody titers (odds ratio: 1.34, 95% CI 0.99-1.72). Seventy percent of the HIV-infected responders maintained protective antibody titers 6 months after vaccination. CONCLUSION: Hepatitis B vaccination should be offered to all HIV-infected ESRD patients because over half of the patients with HIV and ESRD can develop protective antibodies.  相似文献

Presently, there is no consensus regarding the most appropriate diagnostic and therapeutic approach to patients with human immunodeficiency virus (HIV)-associated lymphoepithelial lesions of the major salivary glands. A retrospective review of 60 consecutive patients with lymphoepithelial lesions is presented. Thirty-eight cases were associated with HIV infection. Lesions associated with HIV infection were usually bilateral, multiple, cystic, and associated with lymphadenopathy. In contrast, in those cases without HIV infection, the lesions tended to be solitary and solid. In the HIV-infected group, treatment included surgery, radiotherapy, zidovudine (AZT), and/or cyst aspiration. All therapeutic regimens, other than aspiration alone, were found to be effective. Eighteen of the patients with HIV infection developed the acquired immunodeficiency syndrome (AIDS) during the study period. Surgical treatment is probably not necessary in the majority of HIV-associated cases. Depending upon individual circumstances, treatment with AZT or low-dose radiotherapy is recommended. A diagnostic and therapeutic algorithm is presented as a guide to the management of future cases.  相似文献

HIV infection was previously an absolute contraindication to renal transplantation. However, with the advent of highly active antiretroviral therapy (HAART), renal transplantation using HIV-negative donor kidneys has successfully been employed for HIV-infected patients with end-stage renal failure. In resource-limited countries, places on dialysis programmes are severely restricted; HIV-infected patients, like many others with co-morbidity, are often denied treatment. Kidneys (and other organs) from HIV-infected deceased donors are discarded. The transplantation of HIV-positive donor kidneys to HIV-infected recipients is now a viable alternative to chronic dialysis or transplantation of HIV-negative donor kidneys. This significantly increases the pool of donor kidneys to the advantage of HIV-positive and -negative patients. Arguments are presented that led to our initiation of renal transplantation from HIV-positive deceased donors to HIV-positive recipients at Groote Schuur Hospital, Cape Town.  相似文献

Low testosterone levels are common in both men and women with human immunodeficiency virus (HIV) infection and may contribute to loss of lean body mass and AIDS wasting. Causes of low testosterone levels are complex and may include chronic illness, HIV infection and its complications, medications used to treat HIV and opportunistic diseases, and normal aging-related declines. In the majority of studies addressing the use of testosterone treatment in HIV-infected patients, testosterone has been found to help prevent loss of lean body and muscle mass. Whether the combination of exercise and testosterone is more effective in preventing loss of lean body mass than either therapy alone is not yet clear and warrants further study. In addition to its effects on body composition, testosterone treatment results in improved mood and libido in HIV-infected women and increased bone mineral density in HIV-infected men. Testosterone may thus make a valuable contribution to the treatment of HIV-infected individuals.

Chronic kidney disease (CKD) is a known complication of the human immunodeficiency virus (HIV) but outcomes among HIV-infected patients with kidney disease are unknown. We studied a national sample of 202,927 patients with CKD (stage 3 or higher) for death, end-stage renal disease (ESRD) and the mean annual rate of decline in estimated glomerular filtration rate (eGFR) over a median period of 3.8 years. Within this sample, 0.3% of the patients were diagnosed with HIV, 43.5% were diabetic, whereas the remainder had neither disease. In this national CKD cohort, HIV-infected black patients were at higher risk of death, a similar risk for ESRD and loss of eGFR than black patients with diabetes. HIV-infected white patients experienced higher rates of death but a lower risk of ESRD than their counterparts with diabetes. Our results highlight a need to study mortality and mechanisms of ESRD in the HIV infected population.  相似文献

A spectrum of renal abnormalities has been described in patients infected with the human immunodeficiency virus (HIV) with or without signs of the acquired immunodeficiency syndrome (AIDS). In particular, attention has been focused on a nephropathy characterized clinically by nephrotic proteinuria and rapidly advancing renal insufficiency, and histologically by focal and segmental glomerulosclerosis (FSGS). To evaluate the relationship between HIV infection and structural renal disease, we reviewed all consultations between January 1982 and March 1988 to the Division of Nephrology at San Francisco General Hospital (SFGH), a municipal hospital treating approximately one-third of AIDS cases in San Francisco. Seventy-three consultation requests were received during this period regarding patients with AIDS (48), AIDS-Related Complex (23), or asymptomatic HIV infection (2). Of these, 27 gave evidence of structural renal disease (Group I): 14 had chronic renal insufficiency, in 10 of whom nephrotic proteinuria was also present. However, progression of renal insufficiency to end-stage renal disease (ESRD) in this group did not follow the rapid course described for HIV-associated nephropathy. Renal tissue was examined in 11 Group I patients and showed FSGS in four and a variety of acute and chronic glomerular and tubulointerstitial changes in the others. In 46 Group II patients, consultation was requested for acute renal failure or fluid, electrolyte, and acid-base disturbances. We also reviewed 91 consecutive autopsies performed in patients dying with AIDS at SFGH between 1981 and 1986.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft.  相似文献

Few studies have compared the incidence of end-stage renal disease (ESRD) among individuals with the human immunodeficiency virus (HIV) and diabetes. We followed a national sample of 2,015,891 US veterans over a median peroid of 3.7 years for progression to ESRD. The age- and sex-adjusted incidence of ESRD (per 1000 person-years) among HIV-infected black patients was nearly an order of magnitude higher than among HIV-positive white patients, almost twice that of diabetic whites, and similar to that among diabetic blacks. In multivariate Cox proportional hazards analysis, diabetes was associated with an increased risk of ESRD among white patients, but HIV was not. Among black individuals, however, both HIV and diabetes conferred a similar increase in the risk of ESRD (4- to 5-fold increase compared to white individuals without HIV or diabetes). HIV and diabetes carry a similar risk of ESRD among black patients, highlighting the importance of developing strategies to prevent and treat renal disease among HIV-infected black individuals.  相似文献

The most common manifestation of HIV/AIDS in the kidney is the collapsing variant of focal segmental glomerular sclerosis, HIV-associated nephropathy (HIVAN). Other forms of renal disease in HIV-infected patients include mesangial proliferative glomerulonephritis (GN), membranoproliferative GN, IgA nephropathy, minimal change disease and proliferative immune-complex GN. We present the case of a 42-year-old Caucasian male with HIV infection, treatment associated peripheral neuropathy, nephrotic syndrome and progressive renal failure. The initial and subsequent kidney biopsies showed diffuse proliferative glomerulonephritis resembling diffuse proliferative (WHO class IV) lupus nephritis. There was no clinical or serological evidence of systemic lupus erythematosus (SLE). Proteinuria improved with ACE-inhibitors, and renal function remained relatively stable while receiving highly active antiretroviral therapy (HAART). A precipitous decline in renal function to end-stage renal disease followed a brief period of withdrawal from potent antiretroviral therapy during which the viral load rebounded. Considering previously reported cases, it appears that lupus-like nephritis is a rare but well-defined pattern of immune-complex-induced renal injury seen in HIV-infected patients. It appears to be markedly responsive to HAART.  相似文献

BACKGROUND: Human immunodeficiency virus-associated nephropathy (HIVAN) can be the initial presentation of HIV-1 infection. As a result, many have assumed that HIVAN can occur at any point in the infection. This issue has important implications for appropriate therapy and, perhaps, for pathogenesis. Since the development of new case definitions for acquired immunodeficiency syndrome (AIDS) and better tools to assess infection, the relationship of HIVAN to the time of AIDS infection has not been addressed. In this study, we reassessed the stage of infection at the time of HIVAN diagnosis in 10 patients, and we reviewed all previously published cases applying the new case definitions to assess stage of infection. METHODS: HIVAN was confirmed by kidney biopsy in HIV seropositive patients with azotemia and/or proteinuria. CD4+ cell count and plasma HIV-1 RNA copy number were measured. We also reviewed all published cases of HIVAN to determine if AIDS-defining conditions, by current Centers for Disease Control definitions, were present in patients with biopsy-proven HIVAN. RESULTS: Twenty HIV-1 seropositive patients with proteinuria and an elevated creatinine concentration were biopsied. HIVAN was the single most common cause of renal disease. CD4+ cell count was below 200/mm3 in all patients with HIVAN, fulfilling Centers for Disease Control criteria for an AIDS-defining condition. HIV-1 plasma RNA was detectable in all patients with HIVAN. In reviewing previous reports, an AIDS-defining condition was present in virtually all patients with HIVAN. CONCLUSION: HIVAN develops late, not early, in the course of HIV-1 infection following the development of AIDS. This likely accounts for the poor prognosis noted in previous publications and has implications for pathogenesis. In addition, given the detectable viral RNA levels, highly active antiretroviral therapy is indicated in HIVAN. Highly active antiretroviral therapy may improve survival as well as alter the natural history of HIVAN.  相似文献

Background  The ever-increasing prevalence of human immunodeficiency virus (HIV) infection and the continued improvement in clinical management has increased the likelihood of surgery being performed on patients with this infection. The aim of the review was to assess current literature on the influence of HIV status on surgical decision-making. Methods  A literature review was performed using MEDLINE articles addressing “human immunodeficiency virus,” “HIV,” “acquired immunodeficiency syndrome,” “AIDS,” “HIV and surgery.” We also manually searched relevant surgical journals and completed the bibliographic compilation by collecting cross references from published papers. Results  Results of surgery between noninfected and HIV-infected individuals and between HIV-infected and acquired immunodeficiency syndrome (AIDS) patients are variable in terms of morbidity, mortality, and hospital stay. The risk of major surgery is not unlike that for other immunocompromised or malnourished patients. The multiple co-morbidities associated with HIV infection and the availability of highly active antiretroviral therapy must be considered when assessing and optimizing the patient for surgery. The clinical stage of the patient’s disease should be evaluated with a focus on the overall organ system function. For patients with advanced HIV disease, palliative surgery offers relief of acute problems with improvement in the quality of life. When indicated, diagnostic surgery assists with further decision-making in the medical management of these patients and hence should not be withheld. Conclusion  HIV infection should not be considered a significant independent factor for major surgical procedures. Appropriate surgery should be offered as in normal surgical patients without fear of an unfavorable outcome.  相似文献
