BACKGROUND AND AIMS: Pulmonary hypertension is common in patients with end-stage renal disease, and portends a poor prognosis. There are little data in this population, and previous studies have not evaluated quantitative changes in hemodynamics over time while on maintenance dialysis. This study sought to estimate changes in pulmonary artery systolic pressure (PASP) and right ventricular function over time, and to predict PASP change using clinical variables routinely available at time of initial measurement, in patients on maintenance dialysis...

We report here a typical case of a patient on hemodialysis (HD) for end-stage renal disease (ESRD) in India that highlights some of the management issues encountered in a country with an enormous burden of ESRD and major challenges of underdialysis and management of comorbidities. The patient, a 42-year-old multiparous woman with chronic kidney disease (CKD) stage V, type 2 diabetes mellitus, and hypertension is a homemaker from a middle-class family, living in a large city, with no family history of CKD. From May 2013 to December 2016, she has been receiving twice-weekly maintenance HD for 4 h (intermittent HD); access was via an internal jugular line initially and then via a left brachiocephalic arteriovenous fistula (AVF) from late June 2013...

The incidence of acute kidney injury (AKI) is high in the elderly, who comprise an ever-growing segment of the population. Elderly patients pose a different set of diagnostic and therapeutic challenge owing to their associated comorbidities. AKI in the elderly is associated with an increased risk of mortality, morbidity, prolonged length of stay, and progression to chronic kidney disease. Data regarding the clinical profile of AKI in the elderly from the South Indian population are limited. Hence, we present this analysis of the etiological and prognostic factors associated with AKI in elderly population from South India...

BACKGROUND: Pulmonary hypertension in the setting of renal transplantation has been associated with early allograft dysfunction and increased mortality, but this relationship has not been extensively studied. METHODS: We performed a retrospective cohort study of adult patients who underwent their first renal transplantation in the years 2003-2009 and had pre-transplantation echocardiograms. Pulmonary hypertension was defined as right ventricular systolic pressure ≥40 mm Hg in the absence of left-sided valvular disease and/or left ventricular ejection fraction ≤50%...

Mild to moderate volume expansion is a frequent complication in dialysis patients and acute volume overload, such as acute pulmonary oedema, is one of the most worrying medical emergency in these patients. Estimated systolic blood pressure in the pulmonary artery (ePASP) is an important risk factor of mortality and cardiovascular (CV) events in the general population and in patients on dialysis. Therefore, the assessment of body water in dialysis patients is useful both from the clinical point of view for monitoring fluids as well as for prognostic purposes...

Volume overload is common and associated with adverse outcomes in the hemodialysis population including systemic hypertension, pulmonary hypertension, left ventricular hypertrophy, and mortality. Since the beginning of the era of maintenance dialysis, prescribing and maintaining a dry weight remains the standard of care for managing volume overload on hemodialysis. Reducing dry weight even by relatively small amounts has been shown to improve blood pressure and has been associated with reductions in left ventricular hypertrophy...

Dialysis disequilibrium syndrome (DDS) is a serious neurological complication of hemodialysis, and patients with acute brain injury are at increased risk. We report a case of DDS leading to intracranial hypertension in a patient with anoxic brain injury and discuss the subsequent dialysis strategy. A 13-year-old girl was admitted after prolonged resuscitation from cardiac arrest. Computed tomography (CT) revealed an inferior vena cava aneurysm and multiple pulmonary emboli as the likely cause. An intracranial pressure (ICP) monitor was inserted, and, on day 3, continuous renal replacement therapy (CRRT) was initiated due to acute kidney injury, during which the patient developed severe intracranial hypertension...

OBJECTIVES: Pulmonary hypertension has been reported to occur in a considerable proportion of patients with end-stage renal disease. End-stage renal disease affects the health-related quality of life of patients. There is a lack of specific information on the relation between pulmonary hypertension and health-related quality of life in patients with end-stage renal disease in the literature. We aimed to evaluate this relation in patients undergoing hemodialysis. MATERIALS AND METHODS: This prospective case-control study included 68 patients treated with hemodialysis and 30 healthy participants as controls...

Methylmalonic acidemia (MMA) is an autosomal recessive disorder that can be classified into two types: (1) vitamin B12-responsive and (2) vitamin B12-non-responsive. In MMA cases with long-term survival, renal failure is often a problem, and timing for kidney transplantation for MMA is controversial. We encountered a vitamin B12-non-responsive MMA case for which regular hemodialysis for renal failure was initiated; the patient was 16 years old when she first received regular hemodialysis and 35 years old when she developed pulmonary artery hypertension (PAH)...
