A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.

An island republic in the eastern Mediterranean Sea. Its capital is Nicosia. It was colonized by the Phoenicians and ancient Greeks and ruled successively by the Assyrian, Persian, Ptolemaic, Roman, and Byzantine Empires. It was under various countries from the 12th to the 20th century but became independent in 1960. The name comes from the Greek Kupros, probably representing the Sumerian kabar or gabar, copper, famous in historic times for its copper mines. The cypress tree is also named after the island.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., COLLAGEN; ELASTIN; FIBRONECTINS; and LAMININ).

A subcomponent of complement C1, composed of six copies of three polypeptide chains (A, B, and C), each encoded by a separate gene (C1QA; C1QB; C1QC). This complex is arranged in nine subunits (six disulfide-linked dimers of A and B, and three disulfide-linked homodimers of C). C1q has binding sites for antibodies (the heavy chain of IMMUNOGLOBULIN G or IMMUNOGLOBULIN M). The interaction of C1q and immunoglobulin activates the two proenzymes COMPLEMENT C1R and COMPLEMENT C1S, thus initiating the cascade of COMPLEMENT ACTIVATION via the CLASSICAL COMPLEMENT PATHWAY.

HIV-associated nephropathy is a late, not early, manifestation of HIV-1 infection. (1/170)

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.  (+info)

Up-regulation of Duffy antigen receptor expression in children with renal disease. (2/170)

BACKGROUND: The Duffy antigen chemokine receptor (DARC) is a promiscuous chemokine receptor that binds chemokines from the C-X-C and C-C families. DARC was initially described on red blood cells, but subsequent studies have demonstrated DARC protein expression on renal endothelial and epithelial cells, even in Duffy-negative individuals whose red cells lack DARC. Because approximately 68% of African Americans lack the Duffy/DARC on their red cells, we carried out experiments to identify the specific renal cells expressing DARC protein and mRNA in African American children and to define whether DARC expression was altered in renal inflammatory processes. METHODS: Immunohistochemistry and in situ hybridization studies were done in 28 renal sections from children with each of the following diagnoses: HIV nephropathy (HIVAN), HIV-associated hemolytic uremic syndrome (HIV-HUS), HIV infection without renal disease, HIV-negative children without renal disease, and Argentinean children with classic HUS. RESULTS: The predominant localization of DARC mRNA and protein was found in endothelial cells underlying postcapillary renal venules in all patients studied. However, DARC mRNA and protein were significantly up-regulated in peritubular and glomerular capillaries, collecting duct epithelial cells, and interstitial inflammatory cells in children with HIVAN, HIV-HUS, and classic HUS. CONCLUSION: These findings support the notion that the renal DARC is linked to the inflammatory cascade and that African American children may be at risk of accumulating chemokines in renal tissues.  (+info)

Hepatitis C virus-associated glomerular disease in patients with human immunodeficiency virus coinfection. (3/170)

Chronic infection with hepatitis C virus (HCV) has been linked to the development of glomerular disease. HCV infection is highly prevalent among intravenous drug users, a population that is also at risk for HIV coinfection. This study reports the clinical-pathologic features and outcome of HCV-associated glomerular disease (HCV-GD) in 14 patients with HIV coinfection. All were intravenous drug users and all but one were African-Americans. Renal presentations included renal insufficiency, microscopic hematuria with active urine sediment, hypertension, and nephrotic syndrome or nephrotic-range proteinuria without hypercholesterolemia. Hypocomplementemia and cryoglobulinemia were present in 46 and 33% of patients, respectively. The predominant renal biopsy findings were membranoproliferative glomerulonephritis type 1 or type 3 (Burkholder subtype) in 79% of patients and membranous glomerulopathy with atypical features in 21% (including overlap with collapsing glomerulopathy in one patient). The clinical course was characterized by rapid progression to renal failure requiring dialysis. The overall morbidity and mortality were high with median time of 5.8 mo to dialysis or death. Although most patients died in renal failure, cause of death was primarily attributable to long-term immunosuppression and advanced AIDS. Patients with AIDS had shorter survival than those without (median survival time of 6.1 mo versus 45.9 mo, log-rank test P = 0.02). Only two patients were alive with stable renal function at follow-up of 28.5 mo. In patients with HCV-GD, coinfection with HIV leads to an aggressive form of renal disease that can be easily confused with HIV-associated nephropathy. Although hypocomplementemia, cryoglobulinemia, and more prominent hypertension and microscopic hematuria may provide clues to the presence of HCV-GD, renal biopsy is essential to differentiate HCV-GD from HIV-associated nephropathy.  (+info)

Renal lesions in AIDS: a biopsy and autopsy study. (4/170)

We studied renal lesions at biopsy (20 cases) and at autopsy (21 cases) among patients with the acquired immune deficiency syndrome (AIDS). Nephrotic syndrome with concomitant renal insufficiency was most common indication for biopsy. 85 percent of biopsies showed features of HIV associated nephropathy (HIVAN) which include: Focal segmental glomerulosclerosis (FSGS), glomerular collapse and mesangial hyperplasia. These glomerular changes were always accompanied by tubular microcysts and ultrastructurally, tubuloreticular inclusions (TRI) within the glomerular endothelium were often noted. Changes of HIVAN were also seen in two cases who were HIV negative at the time of biopsy but were positive on repeat testing. Minimal change disease, mesangiocapillary glomerulonephritis and diffuse proliferative lupus nephritis were other biopsy lesions. Autopsy findings were HIVAN (33 percent), tubular necrosis and opportunistic infections. We conclude that HIVAN is a distinct clinicopathologic entity that may sometimes be the first manifestation of the underlying disease state.  (+info)

Renal lesions associated with AIDS--an autopsy study. (5/170)

Kidneys from 55 cases (20 with HIV infection and 35 with AIDS) were studied by routine Haematoxylin and Eosin stains and special stains (PAS, PASM GMS, ZN, Mucicarmine and Congo red) to evaluate, glomerular, interstitial and vascular pathology. Twenty-four of the 35 (68.6%) cases of AIDS showed infective aetiology which included 17 cases (48.5%) of tuberculosis, 5 cases (14.4%) of fungal infection (3 cryptococcus neoformans and 2 candida species) and 2 cases (5.7%) of CMV infection. Other lesions noted were amyloidosis and tubular calcinosis. HIV associated nephropathy (HIVAN) was not detected in any of the cases. Intravenous drug abuse was not a risk factor in our cases which probably explains the absence of HIV associated nephropathy in the present study.  (+info)

Chemokine receptor CCR5 and CXCR4 expression in HIV-associated kidney disease. (6/170)

The chemokine receptors CCR5 and CXCR4 have been identified as essential coreceptors for entry of HIV-1 strains into susceptible cells. Direct infection of renal parenchymal cells has been implicated in the pathogenesis of HIV-associated renal disease, although data are conflicting. The localization of CCR5 and CXCR4 in kidneys with HIV-associated renal disease is unknown. Formalin-fixed, paraffin-embedded renal biopsies from patients with HIV-associated nephropathy (HIVAN) (n = 13), HIV-associated immune complex glomerulonephritis (n = 3), HIV-associated thrombotic microangiopathy (n = 1), and HIV-negative patients with collapsing glomerulopathy (n = 8) were analyzed in this study. Cellular sites of expression of CCR5 and CXCR4 were identified by immunohistochemistry and by in situ hybridization. The presence of HIV-1 was detected by immunohistochemistry and by in situ hybridization. Expression of both chemokine receptors CCR5 and CXCR4 was undetectable in intrinsic glomerular, tubular, and renovascular cells in all analyzed cases. In the presence of tubulointerstitial inflammation, CCR5 and CXCR4 expression was localized to infiltrating mononuclear leukocytes. HIV-1 protein was undetectable by immunohistochemistry in all cases of HIV-associated renal disease. HIV-1 RNA was identified in one case of HIVAN but was restricted to infiltrating leukocytes. HIV-1 RNA was not detected in intrinsic renal cells in all analyzed cases. Identifying the cellular expression of HIV-coreceptors CCR5 and CXCR4 may help to clarify which tissues are permissive for direct HIV infection. These data do not support a role of productive HIV-1 infection of renal parenchymal cells in the pathogenesis of HIV-associated renal disease.  (+info)

Diuretic MAG3 scintirenography in children with HIV nephropathy: diffuse parenchymal dysfunction. (7/170)

HIV nephropathy (HIVN) is prevalent in 15%-56% of HIV-infected children and induces mild to severe progressive nephropathy. METHODS: A total of 33 renal diuretic scintirenographic studies with 99mTc-mercaptoacetyltriglycine (MAG3) were reviewed and analyzed from 23 HIV pediatric patients, 21 of whom had HIVN with varying degrees of renal impairment. Results were compared with 10 studies of control patients of matching ages. Visual interpretation of images and renograms as well as semiquantitative analyses were performed. Variables compared were size of kidneys, time of peak and one-half peak activities, residual (or retained) cortical activity at 20 min, ratio of cortical activity at 2.5-20 min, and ratio of kidney activity to kidney plus background activity at 2 min. The results of MAG3 renal studies were also compared with laboratory data pertaining to creatinine clearance in all patients and with sonography in 17 patients. RESULTS: In most patients with HIVN (18/21), the kidneys were larger than normal, with a diffuse parenchymal dysfunction (decreased uptake, slow processing, and increased retention of activity) and flat renograms, findings similar to those observed in other diffuse parenchymal diseases. In all patients with HIVN, semiquantitative analysis (paired t test) showed statistically significant differences from control patients for all variables. On ANOVA, a statistically significant correlation was found between most scintigraphic parameters and the severity of renal impairment. Of the 17 concurrent sonographic studies in HIVN patients, 7 showed no abnormalities, whereas the results of scintigraphy were abnormal. CONCLUSION: Diuretic MAG3 scintirenography shows nonspecific diffuse parenchymal dysfunction in pediatric patients with HIVN. Such dysfunction may provide corroborative evidence of HIVN and should be recognized when the test is performed for standard indications. Further work is necessary to prove that the test has indeed the high sensitivity and good correlation with the seventy of HIVN suggested in this population; the test may be useful to follow up the progression of disease and the effect of treatment.  (+info)

Podocyte cell cycle regulation and proliferation in collapsing glomerulopathies. (8/170)

BACKGROUND: Mature podocytes are growth-arrested because of the expression of cyclin-dependent kinase inhibitors. Under pathological conditions, podocytes may undergo mitosis, but not cell division. Exceptions to this rule are collapsing glomerulopathies (CGs), including HIV-associated nephropathy (HIVAN) and idiopathic CG, where podocytes undergo a dysregulation of their differentiated phenotype and proliferate. METHODS: To shed light on the mechanism underlying podocyte proliferation in CG, we analyzed the expression of the proliferation marker Ki-67, cyclins (A, D1), cyclin-dependent kinase inhibitors (p27, p57), and podocyte differentiation marker synaptopodin in eight cases of HIVAN and two cases of idiopathic CG. Normal fetal and adult kidneys served as controls. RESULTS: Both HIVAN and idiopathic CG showed a marked reduction in the expression of p27, p57, and cyclin D1 (absent in 69, 62, and 80% of all glomeruli, respectively). Cyclin A and Ki-67 were expressed in 11 and 29% of all glomeruli. Moreover, there was partial loss of synaptopodin and cyclin D1 expression in nonaffected glomeruli. CONCLUSIONS: The loss of p27 and p57 leading to expression of cyclin A may account for the activation of podocyte proliferation in CG. Furthermore, the loss of cyclin D1 from histologically normal glomeruli suggests a possible role of cyclin D1 in mediating the dysregulation of the podocyte cell cycle in CG. These novel findings offer insight into the molecular regulation of mature podocyte differentiation. Podocyte proliferation in CG provides evidence in support of a previously underestimated plasticity of mature podocytes.  (+info)

HIV-infected patients may present with a variety of patterns of renal involvement. Acute renal failure is common and most often a result of sepsis, hypotension, and nephrotoxic agents. It is potentially avoidable, and support through the period of renal failure may lead to resolution of the renal dysfunction. HIV-associated nephropathy is a unique pattern of sclerosing glomerulopathy that ranges in prevalence from 1 to 10% of the HIV-infected population in different geographic locales. This complication of HIV infection will likely present a growing challenge to the medical community as HIV infection continues to spread worldwide. Deciphering the pathogenetic mechanisms of this most rapidly progressive form of focal segmental sclerosis is not only clinically relevant, but will hopefully provide valuable insights into the mediation of the more common idiopathic form of the disease. The potential for improved renal survival of patients with HIV-associated nephropathy has become more realistic with ...
ART for the treatment of HIV may slow the progression of HIV-associated nephropathy (HIVAN) to end-stage renal disease (ESRD); nevertheless, it is predicted that many HIV infected patients on ART will reach ESRD by the next decade. Medications that affect the renin-angiotensin system, such as the ARB valsartan, may be useful in treating HIVAN. In a small study of HIV infected patients with HIVAN treated with the angiotensin-converting enzyme inhibitor (ACEI) fosinopril, kidney function was stable in patients who took the ACEI, but function decreased in patients who did not. These data are promising, and suggest that an ARB like valsartan may also slow the progression of HIVAN and improve patients prognosis. This study will compare valsartan and ART to ART alone in slowing kidney disease progression in people with HIV.. This study will last 96 weeks. All participants will continue taking their current ART regimen during the study and will be randomly assigned to one of two arms: Arm 1 will ...

Answer: A, Collapsing FSGS HIV-associated nephropathy classically demonstrates collapsing FSGS. Other features include increased proximal tubule protein resorption droplets, and microcystic tubular dilatation. While this disease has markedly diminished in the presence of highly active antiretroviral therapy (HAART), the rate is still high in areas of sub-Saharan Africa. Within the United States, approximately 90% of cases occur in African Americans and are associated with genetic mutations in the APOL1 gene (G1/G2 alleles). The typical presentation is that of nephrotic syndrome secondary to widespread foot process effacement seen by electron microscopy. Interestingly, the CD4 count has not shown to be ...

We investigated the association of APOL1 genetic variation in FSGS and HIVAN and have several findings. First, we show, for the first time, that APOL1 G1 and G2 alleles are strongly associated with HIVAN and confirm their association with primary FSGS; the associations are best described by a recessive model. We have more precisely determined the true effect sizes for these alleles for primary FSGS and HIVAN, with OR of 17 and 29, respectively, in a recessive model. These are the strongest effect sizes discovered, to date, for common variants with a complex disease.22 Second, we show that the G1384M allele is probably not required for pathogenesis, as the G1G+ haplotype containing just the G1342G allele can complement the G1GM haplotype containing both variant alleles; we lack data for the other possible combinations (G1G+/ G1G+ or G1G+/ G2). Third, we found no significant differences in glucocorticoid sensitivity in subjects who had received an adequate therapeutic trial. While the numbers of ...
Human immunodeficiency virus-related renal diseases occur in up to 10% of patients infected with HIV. The majority of such patients are black and the commonest pathology seen is HIV-associated nephropathy (HIVAN). This is a clinicopathological entity characterised by proteinuria and rapidly developing renal failure and histologically by a collapsing variant of focal and segmental glomerulosclerosis with acute tubular necrosis and mild interstitial inflammation. It may progress rapidly to end-stage renal disease (within 6 months). HIVAN appears to be the commonest cause of renal disease in HIV-infected patients in South Africa, although the exact prevalence is unknown. The disease affects predominantly black males, although it has been described in patients of mixed race. Current thoughts with regard to pathogenesis revolve around the role of HIV in the renal epithelium and the effects of cytokines, including transforming growth factor-beta and basic fibroblast growth factor, on renal structures. ...
We previously used global Hipk2-null mice in various models of kidney disease to demonstrate the central role of homeodomain-interacting protein kinase 2 (HIPK2) in renal fibrosis development. However, renal tubular epithelial cell-specific (RTEC-specific) HIPK2 function in renal fibrogenesis has yet to be determined. Here, we show that modulation of tubular HIPK2 expression and activity affects renal fibrosis development in vivo. The loss of HIPK2 expression in RTECs resulted in a marked diminution of renal fibrosis in unilateral ureteral obstruction (UUO) mouse models and HIV-associated nephropathy (HIVAN) mouse models, which was associated with the reduction of Smad3 activation and downstream expression of profibrotic markers. Conversely, WT HIPK2 overexpression in RTECs accentuated the extent of renal fibrosis in the setting of UUO, HIVAN, and folic acid-induced nephropathy in mice. Notably, kinase-dead HIPK2 mutant overexpression or administration of BT173, an allosteric inhibitor of ...
Background: Extracellular matrix (ECM) molecules have been increasingly implicated in cardiac remodeling, and in particular the myocardial response to pressure overload. Podocan is a novel member of the small leucin-rich-repeat protein family of ECM proteins. We recently have characterized podocan as an inhibitor of the migration and proliferation of vascular smooth muscle cells. Now we are testing if podocan deficiency has an effect on pressure load-induced cardiac hypertrophy.. Methods and Results: We induced pressure overload cardiac hypertrophy using aortic banding (AB) in mice (age 10-12 weeks) with podocan-/- (n=6) and wild-type (WT) (n=7) genotype. Four weeks after AB, cardiac anatomy and function were assessed by echocardiography. In addition, histological analysis was used to assess the myocardial response to AB. Podocan-deficient mice showed significantly greater cardiac hypertrophy compared with WT mice after AB, whereas no significant differences were observed when comparing ...
When secondary causes are excluded, mechanisms underlying central nervous system angiitis (ACNS) in human immunodeficiency virus (HIV)-infected patients are still not understood and optimal treatment remains undefined.

Opportunistic infections should always be considered in the evaluation of symptomatic patients with advanced HIV/AIDS, although the overall incidence of these infections has decreased. Primary care of HIV infection includes the early detection of some complications through screening at-risk and symptomatic patients with routine laboratory monitoring (e.g., comprehensive metabolic and lipid panels) and validated tools (e.g., the HIV Dementia Scale). Treatment of many chronic complications is similar for patients with HIV infection and those without infection; however, combination antiretroviral therapy has shown beneft for some conditions, such as HIV-associated nephropathy. For other complications, such as cardiovascular disease ...

Central nervous system involvement is a common manifestation of non-Hodgkin lymphoma (NHL) in human immunodeficiency virus (HIV)-infected individuals. The purpose of this study was to review the frequency and pattern of neurologic manifestation of lymphoma in a cohort of HIV-infected individuals with systemic NHL. METHODS. Sixty-two patients with HIV- associated systemic NHL received infusional cyclophosphamide, doxorubicin, and etoposide. Five patients with lymphomatous meningitis at presentation received whole brain radiation therapy plus intrathecal chemotherapy (ITC). Of the remaining 57 patients, prophylactic ITC was ...

A significant association was observed among human immunodeficiency virus (HIV)-positive adult cases in Lusaka, Zambia compared with HIV-negative controls for chronic diarrhea (68% versus 22%; P < 0.05), weight loss (54% versus 30%; P < 0.05), lymphadenopathy (44% versus 15%; P < 0.05), and skin eruption (33% versus 7%; P < 0.05). Among the HIV-positive children, a higher proportion had clinical evidence of tuberculosis when compared with HIV-negative children (8% versus 1%; P < 0.05). The study demonstrated an association between weight loss in HIV-positive adults and children and chronic diarrhea (odds ratio [OR] = 12.7, 95% confidence interval [CI] = 6.4-25.5; P < 0.001), persistent cough (OR = 7.2, 95% CI = 2.9-14.5; P < 0.001), and an age of 31-45 years (OR = 3.8, 95% CI = 1.8-8.3; P < 0.01). The factors associated with mortality in HIV positive patients included chronic diarrhea (OR = 7.4, 95% CI = 1.6-34; P < 0.01), and lymphadenopathy (OR = 3.89, 95% CI = 1.2-12.2; P

Herein, we reported that six of the nine patients (67%) with HIV-associated KS achieved an objective response (PR: N = 5; CR: N = 1) after treatment with immune checkpoint blockade with nivolumab or pembrolizumab. An additional two patients have had ongoing SD for over 6 months, and one patient remains stable for more than 3.5 months. Similar findings were reported by Delyon and colleagues, demonstrating major clinical and metabolic responses in two patients with endemic, non-HIV-associated KS following the administration of nivolumab (21).. Patients with advanced HIV-associated KS tend to have a poor prognosis and limited duration of response to conventional chemotherapy. The current standard of care for advanced HIV-associated KS is liposomal doxorubicin, with RRs of approximately 58% (22). However, responses are usually not durable, with a median PFS of less than 150 days (22, 23). A significant risk of neutropenia is also associated with liposomal doxorubicin, which can further exacerbate ...

HIV associated Lipodystrophy Market: Overview. Changes in body fat concentration, affecting people with HIV, is known as HIV-associated lipodystrophy. The exact causes of this condition is currently unknown, but research suggests that this disorder can occur either due to HIV infection or as a consequence of side effects associated with drugs used in HIV infection treatment, such as Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs), Protease Inhibitors (PIs), etc. The lipodystrophy condition is characterized by metabolic abnormalities, including insulin resistance, and dyslipidemia. The HIV-associated lipodystrophy groups together different clinical conditions, which are lipoatrophy and lipoaccumulation. Lipoatrophy is associated with subcutaneous fat loss, whereas lipoaccumulation is the increase in visceral fat. In certain cases, HIV-associated lipodystrophy may occur as a combination of these two conditions; thus, its treatment and prevalence measurement are difficult.. Download ...
Small heat shock proteins (sHsps) are a group of proteins with molecular mass between 12 and 43 kDa. Currently, 11 members of this family have been classified, namely HspB1 to HspB11. HspB1, HspB2, HspB5, HspB6, HspB7, and HspB8, which are expressed in brain have been observed to be related to the pathology of neurodegenerative diseases, including Parkinsons, Alzheimers, Alexanders disease, multiple sclerosis, and human immunodeficiency virus-associated dementia. Specifically, sHsps interact with misfolding and damaging protein aggregates, like Glial fibrillary acidic protein in AxD, β-amyloid peptides aggregates in Alzheimers disease, Superoxide dismutase 1 in Amyotrophic lateral sclerosis and cytosine-adenine-guanine/polyglutamine (CAG/PolyQ) in Huntingtons disease, Spinocerebellar ataxia type 3, Spinal-bulbar muscular atrophy, to reduce the toxicity or increase the clearance of these protein aggregates ...

  • 10. Immunodeficiency including AIDS / HIV or active autoimmune disease, or on immunosuppressant therapy. (
  • In the autoimmune kidney disease Membranous Nephropathy (MN), the immune system launches an attack against the glomerulus of the kidney, which normally aids in filtering fluids and wastes. (
  • Membranous nephropathy occurs secondary to cancers, autoimmune disorder like lupus and vector illnesses like hepatitis B and malaria. (
  • Results of a prospective, open-label, multicenter, centrally randomized, controlled trial in 97 patients suggested that the combination of the ACEI ramipril with prednisone was more effective than ramipril alone in discouraging progression of renal disease associated with IgA nephropathy. (
  • HIV-positive individuals are at increased risk for a variety of renal disorders, including acute kidney injury (AKI), HIV-associated nephropathy (HIVAN), comorbid chronic kidney disease (CKD), and treatment-related kidney toxicity. (
  • As early renal injury is often masked by the kidneys considerable functional reserve and capacity for repair, the book places special emphasis on the need for improved screening tools and markers that can aid the timely diagnosis of chemically induced renal dysfunction. (
  • The book also cites evidence that exposure to chemicals may have a much greater influence on the incidence of nephropathy and chronic renal failure than previously suspected. (
  • Over time, patients with diabetes may develop cystopathy, nephropathy, and renal papillary necrosis, complications that predispose them to UTIs. (
  • BKV DNA has been detected in blood of re- 5197 to nt 159 of the circular viral genome) by using La- nal transplant patients, and BKV load may be predictive of sergene MegAlign software (DNASTAR Inc., Madison, polyomavirus-associated nephropathy ( 10 ). (
  • Two such examples of BKV-associated diseases are polyomavirus-associated nephropathy (PVAN) and hemorrhagic cystitis (HC) which affect kidney and bone marrow transplant recipients respectively. (
  • Although kidney function, creatinine, and estimated glomerular filtration rate was lower in CO2 at baseline, the incidence of contrast-induced nephropathy was lower in CO2 compared to ICM. (

  • Examples include systemic lupus erythematosus, Alport's syndrome and diabetic nephropathy. (
  • What is Membranous Nephropathy (MN)? (
  • Primary membranous nephropathy (pMN) makes up 80% of the cases and results from the production of specific autoantibodies. (

  • Although FSGS is the predominant glomerular lesion in HIVAN, other reported glomerular lesions in patients with HIV include IgA nephropathy, cryoglobulinemia, amyloidosis, and a lupuslike immune complex glomerulopathy. (
  • The same microvascular changes which often lead to nephropathy and retinopathy in diabetic patients, can lead t. (
  • Did you know that each year diabetes takes more lives than breast cancer and AIDS combined? (
  • This article discusses some of the latest research on how the Mediterranean Diet, and EVOO, aid in the prevention and management of diabetes. (
  • Systemic and local low-grade inflammation and release of proinflammatory cytokines are implicated in the development and progression of diabetes mellitus and diabetic nephropathy. (
  • We propose that careful targeting of TLR2, TLR4, and NLRP3 signalling pathways could be beneficial for the treatment of diabetes mellitus and diabetic nephropathy. (
  • Wada, J & Makino, H 2016, ' Innate immunity in diabetes and diabetic nephropathy ', Nature Reviews Nephrology , vol. 12, no. 1, pp. 13-26. (
  • Going forward, these structures may also be used to identify how antibodies from patients with other diseases recognize the BKV virus particle and thus aid in the development of a vaccine. (
  • With the identification of the causative agent of the acquired immuno- deficiency syndrome (AIDS), a broad spectrum of clinical manifestations has been attributed to infection with the human immunodeficiency virus (HIV). (
  • With the exception of the CDC surveillance definition for AIDS (1,2), no standard definitions for other manifestations of HIV infection have been developed for children. (
  • Physicians from institutions caring for relatively large numbers of HIV-infected children report that only about half of their patients with symptomatic illness related to the infection fulfill the criteria of the CDC surveillance definition for AIDS (6,7). (
  • 1993 Revised classification system for HIV infection and expanded surveillance case definition for AIDS among adolescents and adults. (
  • The acquired immunodeficiency syndrome ( AIDS ) is an immunosuppressed state, caused by infection with the human immunodeficiency virus ( HIV ). (
  • [ 33 ] However, routine late pregnancy testing at 36-37 weeks' gestation in all women is recommended by many experts because infection during pregnancy now makes up a significant percentage of children with AIDS. (
  • 1 Based on 2000 to 2004 surveillance data, the report highlights differences in incidence rates of HIV and AIDS diagnoses by age, sex, ethnicity/race, risk factor/transmission categories, and US geographic region. (
  • In the early phase of diabetic nephropathy, there is microscopic loss of protein-called microalbuminuria, followed by massive loss of protein in the active stage of nephrotic syndrome-called macroalbuminuria. (
  • The distribution of current health disparities in HIV/AIDS and many other chronic illnesses has been shaped by the convergence of multiple individual and community level factors. (
  • C. Check out US HIV/AIDS treatment guidelines :"The progression of chronic HBV to cirrhosis, end-stage liver disease, and/or hepatocellular carcinoma is more rapid in HIV-infected persons than in persons with chronic HBV alone. (
  • Current guidelines 2 advise starting treatment if there is an AIDS-defining illness or a CD4 count below 350 cells/microlitre. (
  • This disease follows viral illness like HIV/AIDS, genetic mutations, high blood pressure, vascular disease, obesity and medication. (
