Background Pulmonary hypertension is a disorder which worsens systemic diseases. One of the important underlying pathology is end stage chronic kidney disease The aim of this study was to assess the incidence of unexplained PHT, and to relate this to the cardiovascular status and arteriovenous fistula characteristics in ESKD patients on maintenance hemodialysis Methods: 159 patients with end stage kidney disease on maintenance hemodialysis were evaluated, 103 were excluded. Clinical, laboratory parameters were recorded. Systolic Pulmonary artery pressure and cardiac functions were evaluated by echocardiography. Flow across arteriovenous fistula was assessed by Doppler sonography. Patients were divided between the group with and without pulmonary hypertension. It was a cross sectional study. Result: Out of 159 patients, 56 patients who fulfilled inclusion criteria were evaluated, 36% had systolic pulmonary artery pressure of 35 mm Hg, mean age was 52.42 ± 9.12 years, 71.4% were males, and mean duration of end stage kidney disease was 33.66 ±11.56 months. Pulmonary hypertension patients were exposed to longer duration of hemodialysis therapy (p=0.0001) as compared to the patients with no pulmonary hypertension group, they also had a longer duration of functional Arterio venous fistula (p=0.0001), and flow across Arterio venous fistula was significantly more in pulmonary hypertension group (p=0.022), and these also had higher cardiac output (p=0.0001).  Patients with Pulmonary hypertension were significantly more anemic, had more hypoalbuminemia and more interdialytic weight gain. Conclusions:  Pulmonary hypertension is frequent in end-stage kidney disease patients on maintenance hemodialysis. It appears to be a late complication of hemodialysis with surgically created AVF with implications on cardiovascular status.

Abstract Background and Aims Patients with end-stage kidney disease (ESKD) are known to have higher plasma concentrations of metabolic waste products than healthy individuals. Patients with Primary Hyperoxaluria (PH), a rare congenital cause of ESKD, suffer from hepatic overproduction of the metabolic end product oxalate. Plasma oxalate (POx) levels are determined in the diagnostic and therapeutic work-up for PH. Remarkably, correct interpretation of these values is hampered by the absence of knowledge concerning POx levels in patients with ESKD due to common causes. Method In this observational study, we obtained POx values in patients with ESKD due to another cause than PH, to establish reference values in this patient group. We collected blood samples from 120 adults with eGFR < 15 mL/min/1.73 m2 who required maintenance hemodialysis or peritoneal dialysis at the Amsterdam UMC. Results While there was a wide variation in POx levels in patients with ESKD, the median was 50 umol/L and lowest values were twice the upper reference limit that applies to healthy individuals (6.7 umol/L). Conclusion This study shows that POx levels of 50 umol/L are not necessarily suggestive for PH which contradicts the current literature. This study could lead to a paradigm shift in the diagnostic and therapeutic work-up for patients with ESKD.

Vitamin D Levels

Vitamin D deficiency actives renin-angiotensin-aldosterone system (RAAS) which affects cardiovascular system. Activation of RAAS is associated with pulmonary hypertension (PHT). Relation between vitamin D deficiency and PHT could be therefore suggested. In  our study we compared pulmonary artery pressure between vitamin D deficiency and control groups. 115 consecutive patients (average age: 61.86 ± 5.86) who have detected very low vitamin D (vitamin D levels < 10 ng/ml) were enrolled. 117 age matched persons (average age: 61.74 ± 5.99) were selected as the control group. All groups underwent transthoracic echocardiography. Routine biochemical measurement of 25-OH vitamin D and parathormon (PTH) levels were performed. Baseline characteristics of the study groups were comparable. Systolic pulmonary artery pressure (SPAP) of patients in  the low vitamin D group was higher than the control groups. As a  result our study, a  relation between vitamin D deficiency and pulmonary artery hypertension was revealed.

The Impact

ABSTRACT Background: Malnutrition is a common problem in patients with end-stage-kidney-disease (ESKD) and is a strong risk factor for morbidity and mortality. ESKDis a maladaptive metabolic state and patients need to increase their dietary protein and calorie intake especially when on maintenance dialysis. In a developing country like India, the economic and knowledge barrier affects the diet of the patient. In this study we assessed the prevalence of malnutrition and the impact of dietary counselling on improvement in nutritional status of the patient. Method: This study enrolled patients undergoing maintenance hemodialysis in our centre between June 2017 and June 2019. The prevalence of malnutrition was assessed by Subjective Global Assessment (SGA). Dietary history was recorded with a 24-hour dietary recall method. The patient was then periodically counselled regarding adequate dietary protein and calorie requirement and was re-assessed for the prevalence of malnutrition at the end of 6 months. Results: The mean age of study cohort was 38.76±10.85 years and 64 % were male.Hypertension (38.89%) and Diabetes (11.11%) were the most common co-morbid illnesses.The prevalence of PEW was 92% at baseline and 86% at the end of 6 months of follow up. There was a significant increase in BMI from 19.97 to 20.38 (p=0.022). Most of the study patients were from very low socioeconomic status (78% Class V modified Prasad's scale). Conclusions: There is a very high prevalence of protein-energy malnutrition among ESKD patients on maintenance haemodialysis. Nutritional counselling resulted in statistically significant improvement in the prevalence of malnutrition. Hence,nutritional counselling must be given regularly to patients with kidney disease.

Purpose: Pulmonary hypertension (PH) is a frequent and serious cardiovascular complication in patients with end-stage renal disease (ESRD) on dialysis. The purpose of this study was to investigate the prevalence of PH and its associated factors in patients with ESRD on maintenance dialysis and predialysis patients. Methods: The medical records of ESRD patients who underwent kidney transplantation between January 2011 and December 2017 were retrospectively reviewed. Demographic and clinical characteristics including echocardiographic findings before joining the waiting list for transplantation were evaluated and compared among groups divided according to dialysis or not and dialysis types. The results of transthoracic Doppler echocardiography were used to determine the pulmonary artery pressure. Pulmonary hypertension was defined as a systolic pulmonary artery pressure (sPAP) greater than 35 mmHg. Univariate and multivariate analyses were used to investigate factors associated with PH. Results: Data from 35 pre-dialysis patients with ESRD, 72 maintenance hemodialysis (HD) and 34 peritoneal dialysis (PD) patients were analysed. Pulmonary hypertension was 20.69% in pre-dialysis patients, 16.7% in HD patients and 14.7% in PD patients (P=0.957). There were negative correlations between sPAP and calcium (r=-0.230, P=0.012), Ca×P(r=-0.210, P=0.021), hemoglobin (r=-0.243, P=0.008) and a positive correlation between sPAP and cardiac output (r=0.481, P=0.000). Cardiac output (CO) was an independent risk factor of sPAP (B=1.431, confidence interval [CI] 95%: 0.687 to 2.175, P=0.000). Conclusion: Incidence of PH was not statistically different in ESRD patients on dialysis and pre-dialysis patients. Uremia may play a major role in the pathogenesis of PH in patients.

Objective Right heart catheterization (RHC) is associated with a higher procedural risk in older adults, but non-invasive estimation of pulmonary hypertension (PH) is a challenge. We aimed to elaborate a non-invasive prediction model to estimate PH. Methods and design We retrospectively analysed 134 older adults (70.0 years ±12.3; 44.9% males) who reported to our clinic with unclear dyspnea between 01/2015 and 01/2020 and had received RHC as a part of their diagnostic workup. Lung function testing, analysis of blood gas samples, 6 min walk distance and echocardiography were performed within 24 hours of RHC. Main outcome measures In a stepwise statistical approach by using an in/exclusion algorithm (using the AIC criterion) we analysed non-invasive parameters to test their value in predicting PH (defined as mean pulmonary artery pressure, PAmean, >25mmHg). Discrimination capability of the final model was measured by the AUC (area under curve) from an ROC (receiver operating characteristics) analysis. Results We yielded a sensitivity of 87.2% and a specificity of 62.5% in a combinatorial logistical model with systolic pulmonary artery pressure (sPAP) and forced vital capacity (VCmax), the discrimination index was 86.7%. The odds ratios for an increase of 10 mmHg of sPAP were 2.99 (2.08–4.65) and 1.86 (1.11–3.21) for a 1 l decrease in VCmax. On their own, VCmax proved to be specific (83.3%), while sPAP was a sensitive (79.1%) predictor for PH. Conclusions We provide a combinatorial model to predict PH from sPAP and VCmax in older adults, which may help to avoid invasive procedures.
