High quality data on efficacy of L-Ornithine L-Aspartate (LOLA) in cirrhotics with bouts of overt hepatic encephalopathy (OHE) is missing. We aimed to evaluate the efficacy of intravenous LOLA in reversal of bouts of OHE in cirrhotics. In this prospective double-blind randomized placebo controlled trial conducted at two tertiary care institutes in India, 370 cirrhotics with bouts of OHE were screened. After exclusion, 193 (52.16%) patients were randomized to receive either intravenous infusions of LOLA (n=98), 30 grams daily or Placebo (n=95) for 5 days...

OBJECTIVES: To preserve renal function, partial nephrectomy (PN) is recommended to patients with small renal masses. However, controversy still exists as to whether prolonged ischemia time adversely affects the incidence of chronic kidney disease (CKD) after PN. We analyzed the effect of prolonged warm ischemia time (WIT) on long-term renal function following PN. MATERIALS AND METHODS: We reviewed data from 1,816 patients who underwent PN for clinical T1 renal tumor...

AIM: Diabetic kidney disease is one of the leading complications of Type 1 diabetes, but its prediction remains a challenge. We examined predictors of rapid decline in estimated GFR (eGFR) in two Type 1 diabetes cohorts: the Coronary Artery Calcification in Type 1 Diabetes (CACTI) and the Pittsburgh Epidemiology of Diabetes Complications (EDC). METHODS: A select subset of participants (CACTI: n = 210 and EDC: n = 98) diagnosed before 17 years of age with Type 1 diabetes duration ≥ 7 years, and follow-up data on eGFR by CKD-EPI creatinine for up to 8 years were included in the analyses...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

Phosphate retention and hyperphosphataemia are associated with increased mortality in chronic kidney disease (CKD) patients. We tested the use of cross-linked iron chitosan III (CH-FeCl) as a potential phosphate chelator in rats with CKD. We evaluated 96 animals, divided equally into 4 groups (control, CKD, CH-FeCl, and CKD/CH-FeCl), over 7 weeks. We induced CKD by feeding animals an adenine-enriched diet (0.75% in the first 4 weeks and 0.1% in the following 3 weeks). We administered 30 mg/kg daily of the test polymer, by gavage, from the third week until the end of the study...

Developmental glaucoma can occur as an isolated or syndromic condition and is genetically heterogeneous. We describe a three-generation family affected with developmental glaucoma, myopia, and/or retinal defects associated with variable craniofacial/dental, auditory, brain, renal, and limb anomalies. Whole exome sequencing identified a heterozygous c.124T> C, p.(Trp42Arg) allele in ADAMTSL1; co-segregation analysis confirmed the presence of this allele in four affected family members. The mutation affects a highly conserved residue and is strongly predicted to have a deleterious effect on protein function...

Lupus nephritis (LN) is a major manifestation of systemic lupus erythematosus (SLE) causing morbidity and mortality in 40-60% of SLE patients. The pathogenic mechanisms of LN are not completely understood. Recent studies have demonstrated the presence of various immune cell populations in lupus nephritic kidneys of both SLE patients and lupus-prone mice. These cells may play important pathogenic or regulatory roles in situ to promote or sustain LN. Here, using lupus-prone mouse models, we showed the pathogenic role of a kidney-infiltrating CD11c(+) myeloid cell population in LN...

Improving long-term renal allograft survival remains an important unmet need. To assess the extent of histologic injury at 10 years after transplantation in functioning grafts, we studied 575 consecutive adult solitary renal transplants performed between 2002 and 2005-77% from living donors and 92% maintained on tacrolimus-based immunosuppression. Ten-year graft survival was 59% and death-censored graft survival was 74%. Surveillance allograft biopsies were assessed at implantation, 5 years and 10 years from 145 patients that reached 10 years...

Herein, we describe a case of early belatacept conversion in a human immunodeficiency virus (HIV)-positive kidney transplant recipient in an effort to improve suboptimal graft function and avoid drug interactions following anti-thymocyte globulin (ATG) administration. We observed improvement in renal function without HIV disease progression or opportunistic infections. Donor-specific antibodies appeared shortly after conversion but cleared without intervention. This case highlights belatacept as a means to improve renal function and avoid significant drug interactions even following ATG induction...

Systemic inflammation in end-stage renal disease (ESRD) is an established risk factor for mortality and a catalyst for other complications which are related to a premature aging phenotype, including muscle wasting, vascular calcification and other forms of premature vascular disease, depression, osteoporosis and frailty. Uremic inflammation is also mechanistically related to mechanisms involved in the aging process, such as telomere shortening, mitochondrial dysfunction, and altered nutrient sensing, which can have direct effect on cellular and tissue function...

Hospitalization is known to occur frequently in the first 6 months following liver transplantation (LT). Using a novel data linkage between the Scientific Registry of Transplant Recipients and Centers for Medicare and Medicaid Services, our study has two objectives: (i) determine risk factors for "early" hospitalization (i.e., within 6 months of LT) (ii) quantify the importance of hospitalization history in the first 6 months with respect to subsequent patient survival (i.e., survival, conditional on surviving 6 months post-LT)...

Acute kidney injury (AKI) represents a group of complicated syndromes with a high mortality rate. The administration of adipose-derived mesenchymal stem cells (ADMSCs) has been tested as a possible treatment method for AKI. The long-term evaluation of AKI induced by ischemia/reperfusion (IR) and the probable renal protection of ADMSCs are limited. In this study we have established a rat AKI model induced by IR and investigated the possible protective effects of ADMSCs. Adult Sprague-Dawley (SD) rats were divided into three groups (n=6/each group)...

Over the past decade, understanding about feedback mechanisms involving the heart, lung and kidney is significantly improved. Each organ injury may trigger hemodynamic, neuro-hormonal and cellular pathway that may damage diverse organs. Recurrent acute on chronic injury may lead to the advanced stage of disease. On the other hand, chronic pathological conditions may decrease functional reserve leading to a high susceptibility to acute injury. Assessment of functional reserve and dosage of novel biomarkers may allow an early diagnosis and treatment...
