Objective The aim of this cross‐sectional study was to evaluate the association between periodontitis and different severities of chronic kidney disease (CKD) in predialytic patients. Materials and Methods Demographic, socioeconomic, and medical data of 139 patients from the nephrology service of one university hospital in Porto Alegre, Brazil, were obtained through interview and clinical records. Full‐mouth six‐sites per tooth periodontal examinations were performed. Associations between periodontitis, stages of CKD, and estimated glomerular filtration rate (eGFR) were estimated by multivariable models adjusted for sex, smoking, vitamin D supplementation, physical activity, and renal treatment duration. CKD was classified based on eGFR (<60 ml/min/1.73 m2) estimated by the Chronic Kidney Disease Epidemiology Collaboration equation. Results Patients with severe periodontitis, compared to those without severe periodontitis, had 2.8 (95% CI: 1.25–6.62) and 3.4 (95% CI: 1.27–9.09) times higher risk of being in stages 4 and 5 of CKD, respectively. Having ≥ 2 teeth with clinical attachment loss (CAL) ≥6 mm increased 3.9 times the risk of being in stage 5 of CKD. Patients with severe periodontitis and ≥2 teeth with CAL ≥ 6 mm had 4.4 ml/min/1.732 and 5.2 ml/min/1.732 lower eGFR (p‐values < .05), respectively. Conclusion Severe periodontitis was associated with poor renal conditions in predialytic CKD patients, strengthening the importance of periodontal evaluation in such patient population.

OBJECTIVES:To describe the prevalence of the reduced ankle-brachial index (ABI) in patients with heart failure (HF) with preserved ejection fraction (HFpEF) attended at a HF clinic in the metropolitan region of Porto Alegre, and to compar the patients to those with reduced ejection fraction (HFrEF).METHODS:A descriptive observational study, included patients referred to the heart failure clinic in HU-Ulbra with HFpEF or HFrEF and diastolic dysfunction, and measurements of ABIs using vascular Doppler equipment were performed in both groups.RESULTS:The sample consisted of 106 patients with HF, 53.9% of the patients had HFpEF, and 19.4% had a diagnosis of peripheral arterial disease (PAD) (ABI less than 0.9). PAD was identified in 24.1% of the patients with HFpEF, while15.8% of patients in the HFrEF group were diagnosed with PAD.CONCLUSION:Our results did not identify a significantly different prevalence of altered and compatible PAD values in patients with HFpEF. However, we showed a prevalence of 19.4%, a high value if we consider similar populations.
