METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.展开更多

The main diseases that lead to chronic kidney disease are frequent entities as diabetes mellitus, hypertension and glomerulopathies. One of the clinical markers of kidney disease progression is proteinuria. Moreover, the histological hallmark of kidney disease is sclerosis, located both in the glomerular and in the interstitial compartments. Glomerulosclerosis underscores an irreversible lesion that is clinically accompanied by proteinuria. In this regard, proteinuria and glomerular sclerosis are linked by the cell that has been conserved phylogenetically not only to prevent the loss of proteins in the urine, but also to maintain the health of the glomerular fltration barrier: The podocyte. It can then be concluded that the link between proteinuria, kidney disease progression and chronic kidney disease is mainly related to the podocyte. What is this situation due to? The podocyte is unable to proliferate under normal conditions, and a complex molecular machinery exists to avoid its detachment and eventual loss. When the loss of podocytes in the urine, or podocyturia, is taking place and its glomerular absolute number decreased, glomerulosclerosis is the predominant histological feature in a kidney biopsy. Therefore, tissular podocyte shortage is the cause of proteinuria and chronic kidney disease. In this regard, podocyturia has been demonstrated to precede proteinuria, showing that the clinical mana-gement of proteinuria cannot be considered an early intervention. The identifcation of urinary podocytes could be an additional tool to be considered by nephrologists to assess the activity of glomerulopathies, for follow-up purposes and also to unravel the pathophysiology of podocyte detachment in order to tailor the therapy of glomerular diseases more appropriately.展开更多

Group A: BMI 〈 25, n = 22; Group B: BMI 25-30, n = 15; Group C: BMI 〉 30, n = 20. Diuresis, hematocrit, albumin, C-reactive protein, Malnutrition infammatory score, Pro-BNP, Troponin T, leptin and in-sulin levels are expressed as median and ranges (r). RESULTS: Albumin (g/dL): GA vs GC, 3.70 (r2.20-4.90) vs 3.85 (r3.40-4.90), P = 0.02. Diuresis (mL/d): GA 690 (r0-1780); GB 660 (r60-1800); GC 840 (r40-2840). Diuresis GA vs GC, P = 0.01. Leptin (ng/mL): GA vs GC, 3.81 (r0.78-69.60) vs GC, 32.80 (r0.78-124.50), P 〈 0.001. Insulin (μU/mL): GA vs GB, 7 (r2-44) vs 11.50 (r4-38), P = 0.02; GA vs GC, 7 (r2-44) vs 19.5 (r5-155), P = 0.0001. Troponin T and Pro-BNP levels were not different. Significant correlations: GC, Insulin-UF: ρ= 0.53; P = 0.03; TroponinT-diuresis: ρ = -0.48, P 〈 0.05; Pro-BNP-diuresis: ρ = -0.39, P 〈 0.01; Troponin T-ProBNP: ρ = 0.77, P 〈 0.0001; albumin-Troponin T: ρ = -0.66, P 〈 0.0001; albumin-ProBNP: ρ = -0.44, P 〈 0.05.CONCLUSION: High BMI associated positively with higher diuresis and albuminemia, and negatively with TropT and Pro-BNP. High BMI-associated better survival may be explained by better urinary output, lowering cardiovascular stress.展开更多

The differ...Primary focal and segmental glomerulosclerosis(FSGS) may be due to genetic or acquired etiologies and is a common cause of nephrotic syndrome with high morbidity that often leads to end-stage renal failure. The different available therapeutic approaches are unsuccessful, in part due to partially deciphered heterogeneous and complex pathophysiological mechanisms. Moreover, the term FSGS, even in its primary form, comprises a histological description shared by a number of different causes with completely different molecular pathways of disease. This review focuses on the latest developments regarding the pathophysiology of primary acquired FSGS caused by soluble factor urokinase type plasminogen activator receptor, a circulating permeability factor involved in proteinuria and edema formation, and describes recent advances with potential success in therapy.展开更多

Monitored clinical outcome events (COEs) included malignant neoplasms, HBV disease progres-sion events, and deaths. An external event adjudication com-mittee (EAC) was convened to provide real-time review of reported COEs to optimize data quality, and minimize poten-tial adverse effects of the large cohort, interdisciplinary out-come assessments, geographic scope, and long duration. Methods:The EAC comprised an international group of hep-atologists and oncologists with expertise in diagnosis of tar-geted COEs. The EAC reviewed and adjudicated COEs according to prospectively defined diagnostic criteria cap-tured in the EAC charter. Operational processes, including da-ta collection and query procedures, were implemented to optimize efficiency of data recovery to maximize capture of adjudicated COEs, the primary study outcome measure. Results: A total of 1724 COEs were reported and 1465 of these events were adjudicated by the EAC as reported by the investigators (85.0% overall concordance). Concordance by COE type varied: deaths, 99.6%;hepatocellular carcino-ma (HCC), 83.3%;non-HCC malignancies, 88.0%;non-HCC HBV disease progression, 68.2%. Reasons for lack of con-cordance were most commonly lack of adequate supporting data to support an adjudicated diagnosis or evidence that the event pre-dated the study. Conclusions: The REALM EAC performed a critical role in ensuring data quality and consis-tency;EAC performance was facilitated by well-defined diag-nostic criteria, effective data capture, and efficient operational processes.
