RESUMEN

BACKGROUND: Encapsulated peritoneal sclerosis (EPS) is a multifactorial chronic intra-abdominal inflammatory disorder affecting the peritoneum diffusely. The aim of this study was to evaluate the rates of EPS in our peritoneal dialysis (PD) population, to perform a general assessment of the clinical presentation and to determine the outcome of affected patients and risk factors. METHODS: The medical records of consecutive 384 patients who started PD therapy between January 2001 and November 2016 were evaluated. Socio-demographic characteristics, comorbidities, PD therapy details and infectious complications were recorded. Medical records were examined to make sure that the cases met the ISPD criteria for EPS diagnosis including clinical features and either radiological and/or histopathological confirmation. Patients diagnosed with EPS were identified, and the incidence, clinical presentation, treatments and recent status of the patients were reviewed. Factors that might be associated with EPS formation and mortality were investigated. RESULTS: Two hundred one of 384 patients were female, mean age was 45.9±15.6 years and mean PD follow up time were 42.6±35 months. EPS was developed in 26 patients and EPS development rate was 6.7%. PD follow-up period and duration of hypertonic solution usage were longer in patients with EPS (P<0.001 and P=0.017 respectively). Patients with and without EPS were similar in terms of modality (P=0.21) but treatment duration with APD modality was longer in patients with EPS (P<0.001). The PD follow-up period was found to be a predictor of EPS formation (P<0.001, RR:1.034 [95% CI: 1.020-1.047]). Age (P<0.001, RR:1.039 (95% CI: 1.024-1.053) and use of hypertonic dialysis solution (P=0.007, RR:0.979 (95% CI: 0.965-0.994)) were the factors affecting survival in EPS patients. CONCLUSIONS: EPS is a relatively rare but fatal complication of peritoneal dialysis and extension of PD duration is a risk for EPS formation. Younger age and usage of hypertonic dialysis solution affects mortality in patients with EPS.

RESUMEN

OBJECTIVES: The goal of this study was to evaluate the relationship between serum albumin levels and 24-hour ambulatory blood pressure monitoring (24-h ABPM) recordings in non-diabetic essential hypertensive patients. METHODS: A total of 354 patients (mean [SD] age: 55.5 [14.3] years, 50% females) with essential hypertension and 24-h ABPM recordings were included. Patient 24-h nighttime and daytime ABPM values, systolic and diastolic dipping status and average nocturnal dipping were recorded. The correlations between serum albumin levels and nocturnal systolic and diastolic dipping were evaluated, and correlates of average nocturnal systolic dipping were determined via a linear regression model. RESULTS: Overall, 73.2% of patients were determined to be non-dippers. The mean (SD) levels of serum albumin (4.2 [0.3] g/dL vs. 4.4 [0.4] g/dL, p<0.001) and the average nocturnal systolic (15.2 [4.8] mmHg vs. 0.3 [6.6] mmHg, p<0.001) and diastolic dipping (4.2 [8.6] mmHg vs. 18.9 [7.0] mmHg, p<0.001) were significantly lower in non-dippers than in dippers. A significant positive correlation was noted between serum albumin levels and both systolic (r=0.297, p<0.001) and diastolic dipping (r=0.265, p<0.001). The linear regression analysis revealed that for each one-unit increase in serum albumin, the average nocturnal dip in systolic BP increased by 0.17 mmHg (p=0.033). CONCLUSION: Our findings indicate an association between serum albumin levels and the deterioration of circadian BP rhythm among essential hypertensive patients along with the identification of a non-dipper pattern in more than two-thirds of patients. Our findings emphasize the importance of serum albumin levels, rather than urinary albumin excretion, as an independent predictor of nocturnal systolic dipping, at least in non-diabetic essential hypertensive patients with moderate proteinuria.

RESUMEN

OBJECTIVE: To evaluate the relationship between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and inflammation in end-stage renal disease (ESRD) patients on maintenance hemodialysis (HD). METHODS: 100 ESRD patients on maintenance HD (mean ± SD age: 52.3 ± 1.7 years, 52% were males) were included in this cross-sectional study. Data on patient demographics, dry weight, body mass index, duration of HD (months), etiology of ESRD, delivered dose of dialysis (spKt/V), complete blood count, blood biochemistry and inflammatory markers including hs-CRP (mg/L), TNF-α (pg/mL), NLR, and PLR were recorded in all patients and compared in patients with hs-CRP levels of ≤ 3 mg/L vs. > 3 mg/L. other study parameters were also recorded. RESULTS: Compared to patients with lower hs-CRP levels, patients with hs-CRP levels of > 3 mg/L had significantly higher values for NLR (3.7 ± 0.2 vs. 2.7 ± 0.2, p < 0.01) and PLR (150.7 ± 6.9 vs. 111.8 ± 7.0, p < 0.001). Both NLR and PLR were positively correlated with hs-CRP (r = 0.333, p = 0.01 and r = 0.262, p = 0.001, respectively) and negatively correlated with transferrin saturation (%) (r = -0.418, p = 0.001 and r = -0.309, p = 0.002, respectively). CONCLUSION: Our findings in a cohort of ESRD patients on maintenance HD revealed higher values for NLR and PLR in patients with higher levels of inflammation along with a significant positive correlation of both NLR and PLR with hs-CRP levels. Being a simple, relatively inexpensive and universally available method, whether or not calculation of NLR and PLR offers a plausible strategy in the evaluation of inflammation in ESRD patients in the clinical practice should be addressed in larger scale randomized and controlled studies.
