ABSTRACT
Introduction: Cardiovascular diseases are associated with increased morbidity and mortality among CKD (chronic kidney disease) population. Recent studies have found increasing prevalence of PH (pulmonary hypertension) in CKD population. Present study was done to determine prevalence and predictors of LV (left ventricular) systolic dysfunction, LVDD (left ventricular diastolic dysfunction) and PH in CKD 3b-5ND (non-dialysis) patients. Methods: A cross sectional observational study was done from Jan/2020 to April/2021. CKD 3b-5ND patients aged ≥15 yrs were included. Transthoracic 2D (2 dimensional) echocardiography was done in all patients. PH was defined as if PASP (pulmonary artery systolic pressure) value above 35mm Hg, LV systolic dysfunction was defined as LVEF (left ventricular ejection fraction)≤50% and LVDD as E/e′ ratio >14 respectively. Multivariate logistic regression model was done to determine the predictors. Results: A total of 378 patients were included in the study with 103 in stage 3b, 175 in stage 4 and 100 patients in stage 5ND. Prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. Predictors of PH were duration of CKD, haemoglobin, serum 25-OH vitamin D, serum iPTH (intact parathyroid hormone) and serum albumin. Predictors of LVDD were duration of CKD and presence of arterial hypertension. Predictors of LV systolic dysfunction were eGFR (estimated glomerular filtration rate), duration of CKD, serum albumin and urine protein. Conclusion: In our study of 378 CKD 3b-5ND patients prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. (AU)
Introducción: Las enfermedades cardiovasculares se asocian a un aumento de la morbilidad y la mortalidad entre la población con enfermedad renal crónica (ERC). Estudios recientes han encontrado un aumento de la prevalencia de la hipertensión pulmonar (HP) en la población con ERC. El presente estudio se llevó a cabo para determinar la prevalencia y los predictores de la disfunción sistólica del ventrículo izquierdo (VI), la disfunción diastólica del VI y la hipertensión pulmonar en pacientes con ERC 3b -5ND (sin diálisis). Métodos: Se realizó un estudio observacional transversal desde enero/2020 hasta abril/2021. Se incluyeron pacientes con ERC 3b -5ND de edad ≥15 años. Se realizó una ecocardiografía transtorácica 2D (bidimensional) a todos los pacientes. La HP se definió como un valor de presión sistólica de la arteria pulmonar superior a 35mm Hg, la disfunción sistólica del VI se definió como una fracción de eyección del ventrículo izquierdo ≤ 50% y la DVL como una relación E/e′>14 respectivamente. Se realizó un modelo de regresión logística multivariante para determinar los predictores. Resultados: Un total de 378 pacientes fueron incluidos en el estudio con 103 en estadio 3b, 175 en estadio 4 y 100 pacientes en estadio 5ND. La prevalencia de la HP fue del 12,2%, la disfunción sistólica del VI fue del 15,6% y la DVL fue del 43,65%. Los predictores de la HP fueron la duración de la ERC, la hemoglobina, la vitamina D 25-OH en suero, la iPTH en suero (hormona paratiroidea intacta) y la albúmina en suero. Los predictores de la EVL fueron la duración de la ERC y la presencia de hipertensión arterial. Los predictores de la disfunción sistólica del VI fueron la tasa de filtración glomerular estimada, la duración de la ERC, la albúmina sérica y las proteínas en orina. Conclusión: En nuestro estudio de 378 pacientes con ERC 3b-5ND la prevalencia de la HP fue del 12,2%, la disfunción sistólica del VI fue del 15,6% y la DVL fue del 43,65%. (AU)

Background: With the variable genotype-phenotype expression of autosomal dominant polycystic kidney disease (ADPKD) and availability of novel targeted therapies, it is important to find predictors for rapid progression. The PROPKD score, consisting of genetic and clinical parameters like sex, hypertension, and urological events, is a useful tool in predicting the risk of progression. This study was aimed to determine the risk of ADPKD progression in Indian patients using the PROPKD score. Materials and Methods: A retrospective study was done from 2006 to 2021. ADPKD patients with ESRD were included in the study. Scoring was done as per the PROPKD score as follows: male sex: 1, onset of hypertension before 35 years: 2, first urological event before 35 years: 2, PKD1 truncating mutation: 4, PKD1 non-truncating mutation: 2, and PKD2 mutation: 0. Two types of risk classifications were done as follows: (a) considering the clinical variables in all 73 patients (male sex, onset of hypertension before 35 years, and first urological event before 35 years), they were classified into three risk groups: low-risk group (0-1), intermediate-risk group (2-3), and high-risk group (4-5) and (b) considering the clinical variables and type of mutation in 39 patients, they were classified into three risk groups: low-risk group (0-3), intermediate-risk group (4-6), and high-risk group (7-9). Results: Total number of patients included was 73, with the median age at ESRD being 54 years. High-risk group of clinical variables with hazard ratio (HR) of 4.570 (2.302-9.075, P < 0.001) and high-risk group of the PROPKD score with HR of 6.594 (1.868-23.284, P = 0.003) were associated with early ESRD. High-risk groups of both classifications were associated with early ESRD. Conclusion: High-risk groups based on the PROPKD scoring and clinical variables were associated with early progression to ESRD.

INTRODUCTION: Early response to therapy is associated with favourable long-term outcome in LN. The working group of revision of ISN/RPS classification guidelines for LN recommended modified National Institute of Health (NIH) activity and chronicity scoring system to evaluate active and chronic lesions. Data on usefulness of modified NIH scoring system to determine complete renal response (CR) in LN are sparse. METHODS: We retrospectively studied 80 LN patients diagnosed from June/2018 to April/2020, who has followed up for more ≥ 6 months in our hospital. CR was defined by inactive urinary sediment, urine PCR of 0.5 g/g in a 24 h urine collection and normalization/stabilization of renal function. Pathologic lesions were described as per revised 2018 ISN/RPS classification and the modified NIH scoring system. Patients were grouped by AI (low, 0-5; moderate, 6-11; high, 12-24) and CI (low, 0-2; moderate, 3-5; high, 6-12). Time to event was analysed using Kaplan-Meier curves. Prognostic variables for CR were analysed by multivariable Cox proportional hazard models. RESULTS: With a median follow-up of 8 months, 50 patients (62.5%) achieved CR. Kaplan-Meier curves showed lower CR with high AI groups (p value = 0.001) and moderate/high CI groups (p value < 0.001). Moderate and high CI with HR of 0.088 (0.034-0.229) p value < 0.001 and Glomerulosclerosis Score with HR of 0.155 (0.072-0.331) p value < 0.001 were significant determinant of CR. CONCLUSION: Moderate and high CI scores were associated with lower chances of CR in LN. Glomerulosclerosis of CI was significant determinant of CR.
