BackgroundThere are many clinical practice guidelines (CPGs) in Nephrology; however, there is no evidence that their availability has improved the clinical competence of physicians or the outcome of patients with chronic kidney disease (CKD). This study was aimed to evaluate the effect of implementation of CPGs for early CKD on family physicians (FP) clinical competence and subsequently on kidney function preservation of type 2 diabetes mellitus (DM2) patients at a primary healthcare setting.MethodsA prospective educative intervention (40-h) based on CPGs for Prevention, Diagnosis and Treatment of Early CKD was applied to FP; a questionnaire to evaluate clinical competence was applied at the beginning and end of the educative intervention (0 and 2 months), and 12 months afterwards. DM2 patients with CKD were evaluated during 1-year of follow-up with estimated glomerular filtration rate (eGFR) and albuminuria.ResultsAfter educative intervention, there was a significant increase in FP clinical competence compared to baseline; although it was reduced after 1 year, it remained higher compared to baseline. One-hundred thirteen patients with early nephropathy (58 stage 1, 55 stage 2) and 28 with overt nephropathy (23 stage 3, 5 stage 4) were studied. At final evaluation, both groups maintained eGFR [(mean change) early 0.20 ± 19 pNS; overt 0.51 ± 13 mL/min pNS], whereas albuminuria/creatinuria (early −67 ± 155 p < 0.0001; overt −301 ± 596 mg/g p < 0.0001), systolic blood pressure (early −10 ± 18 p < 0.05; overt −8 ± 20 mmHg p < 0.05), and total cholesterol (early −11 ± 31 p < 0.05; overt −17 ± 38 mg/dL p < 0.05) decreased. Diastolic blood pressure, waist circumference and LDL-cholesterol were also controlled in early nephropathy patients.ConclusionsCPGs for Prevention, Diagnosis and Treatment of CKD, by means of an educative intervention increases FP clinical competence and improves renal function in DM2 patients with CKD.
Triggering receptor expressed on myeloid cells (TREM)-1 is a potent and early amplifier of the inflammatory response expressed on neutrophils and monocytes/macrophages. TREM-1, and its soluble form (sTREM-1), are increased in sepsis and other noninfectious inflammatory conditions. However, virtually no data are available in kidney disease. To determine serum sTREM-1 and its associated variables in patients on hemodialysis (HD), cross-sectional study including 264 HD patients and 148 controls. sTREM-1 was measured by quantitative sandwich enzyme immunoassay; soluble tumor necrosis factor receptor-1 (sTNF-R1), interleukin-6 (IL-6), and C-reactive protein (CRP) were also measured. All inflammation markers were significantly higher in HD patients than controls. Median (IQR) sTREM-1 was 1,006 (613–1,650) pg/mL but undetectable in controls. Considering only HD patients, sTREM-1 was positively correlated with IL-6 (r = 0.19, p = 0.008), and its levels were significantly higher in patients with arteriovenous fistula than in those with temporary catheter (1,226 vs. 743 pg/mL), in patients with 3 HD sessions/week than in those with 2 sessions/week (1,150 vs. 646 pg/mL), and in patients with >1 year on HD than in those with ≤1 year (1,100 vs. 948 pg/mL), whereas they were not different regarding age or presence of infection. Serum sTREM-1, sTNF-R1, IL-6, and CRP were higher in HD patients compared to controls. In HD patients, sTREM-1 displayed higher levels in individuals with arteriovenous fistula, 3 sessions/week and longer vintage, but not in those with infection or older age; in multivariate analysis, only the first two variables significantly predicted higher sTREM-1 levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
