Abstract

Chronic kidney disease (CKD) is associated with high morbidity and mortality rates, main causes related with cardiovascular disease (CVD) and bone mineral disorder (CKD-BMD). Uremic toxins, as advanced glycation end products (AGEs), are non-traditional cardiovascular risk factor and play a role on development of CKD-BMD in CKD. The measurement of skin autofluorescence (sAF) is a noninvasive method to assess the level of AGEs in tissue, validated in CKD patients. The aim of this study is analyze AGEs measured by sAF levels (AGEs-sAF) and its relations with CVD and BMD parameters in HD patients. Twenty prevalent HD patients (HD group) and healthy subjects (Control group, n = 24), performed biochemical tests and measurements of anthropometric parameters and AGEs-sAF. In addition, HD group performed measurement of intact parathormone (iPTH), transthoracic echocardiogram and radiographies of pelvis and hands for vascular calcification score. AGEs-sAF levels are elevated both in HD and control subjects ranged according to the age, although higher at HD than control group. Single high-flux HD session does not affect AGEs-sAF levels. AGEs-sAF levels were not related to ventricular mass, interventricular septum or vascular calcification in HD group. AGEs-sAF levels were negatively associated with serum iPTH levels. Our study detected a negative correlation of AGEs-sAF with serum iPTH, suggesting a role of AGEs on the pathophysiology of bone disease in HD prevalent patients. The nature of this relation and the clinical application of this non-invasive methodology for evaluation AGEs deposition must be confirmed and clarified in future studies. A doença renal crônica (DRC) apresenta elevadas taxas de morbidade e mortalidade, sendo a doença cardiovascular (DCV) e o distúrbio mineral e ósseo da DRC (DMO-DRC) complicações frequentes. As toxinas urêmicas, dentre elas os produtos finais da glicação avançada (AGEs), são fatores de risco cardiovascular não tradicionais e se encontram envolvidas no desenvolvimento do DMO-DRC na DRC. A medida da autofluorescência da pele (sAF) é método não invasivo para quantificação do acúmulo tecidual de AGEs validado em pacientes portadores de DRC. O objetivo deste estudo é avaliar as relações entre os AGEs medidos por sAF (AGEs-AF) e parâmetros de DCV e DMO-DRC em pacientes em hemodiálise (HD). 20 pacientes em HD (grupo HD) e 24 indivíduos hígidos (grupo controle) foram submetidos à análise bioquímica sérica, medidas antropométricas e de sAF. O grupo HD realizou medida de hormônio intacto da paratireoide (PTHi), ecocardiograma transtorácico e radiografias de pelve e mãos para pesquisa de calcificação vascular. Os níveis de AGEs-sAF foram elevados para a idade nos grupos HD e controle, porém mais elevados no grupo HD. Sessão única de HD de alto-fluxo não afetou os níveis de AGEs-sAF. Os níveis teciduais de AGEs não se correlacionaram com massa ventricular, espessura de septo interventricular ou calcificação vascular no grupo HD. Os níveis de AGEs-sAF se correlacionaram negativamente com os níveis séricos de PTHi. Nosso estudo detectou correlação negativa entre os níveis de AGEs-sAF e os níveis séricos de PTHi, sugerindo que os AGEs estejam envolvidos na fiosiopatologia da doença óssea em pacientes em HD. A natureza desta relação e a aplicação clínica deste método não invasivo de avaliação do acúmulo tecidual de AGEs deve ser confirmada e elucidada por estudos futuros.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 October 2017.
All research outputs
#19,951,180
of 25,382,440 outputs
Outputs from Jornal Brasileiro de Nefrologia
#256
of 365 outputs
Outputs of similar age
#236,513
of 324,143 outputs
Outputs of similar age from Jornal Brasileiro de Nefrologia
#1
of 1 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 365 research outputs from this source. They receive a mean Attention Score of 2.5. This one is in the 27th percentile – i.e., 27% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 324,143 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
