Abstract Background Patients with end-stage renal disease (ESRD) are at a higher risk for chronic hepatitis, liver cirrhosis (LC) and mortality than the general population. Optimal modalities of replacement therapy ESRD patients concomitant remain controversial. We investigated long-term outcome among dialysis in an endemic area. Methods Using Taiwan’s National Health Insurance claim data (NHRI-NHIRD-99182), performed longitudinal cohort study to investigate impact comorbidities on patients....

Both hypokalemia (hypoK) and hyperkalemia (hyperK) are life-threatening to hemodialysis (HD) patients. This study was conducted compare their clinical characteristics long-term survival.Patients were divided into three groups according the last mid-week predialysis serum potassium concentrations: hypoK (<3.5 mEq/l), normoK (between 3.5 5.5 hyperK (>5.5 mEq/l). The maximal duration of follow-up period 54 months.Compared with group,patients in group older (p <0.05), had a higher incidence...

Diabetes mellitus is the most common chronic disease in world, and a wide range of drugs, including Chinese herbs, have been evaluated for treatment associated metabolic disorders. This study investigated potential hypoglycemic renoprotective effects an extract from solid-state fermented mycelium Cordyceps sinensis (CS). We employed KK/HIJ diabetic mouse model, which mice were provided with high-fat diet 8 weeks to induce hyperglycemia, followed by administration CS or rosiglitazone 4...

A high sensitivity C-reactive protein to albumin ratio (hs-CRP/Alb) predicts mortality risk in patients with acute kidney injury. However, it varies dynamically. This study was conducted evaluate whether a variation of this marker associated long-term outcome clinically stable hemodialysis (HD) patients.hs-CRP/Alb checked bimonthly 284 HD outpatients throughout all 2008. Based on the "slope" trend equation derived from 5-6 hs-CRP/alb ratios for each patient, total number divided into...

The role of specific pathological findings in the upper gastrointestinal tract chronic renal failure remains uncertain. Most studies were conducted West, and number subjects was small. We have tried to look at that problem Taiwan. Endoscopy evaluate source hemorrhage performed 698 patients over a 37-month period; represents 4.4% all undergoing endoscopy for miscellaneous reasons time span. Fifty-eight (8.3%) who had been hemodialyzed selected, as 640 control did not failure. Patients with...

Systemic lupus erythematosus (SLE) patients are associated with insulin resistance and at higher risk to develop diabetes mellitus (DM). SLE DM could lead renal failure respectively. However, it is unknown whether increases the of end-stage disease (ESRD) in patients. This study aimed evaluate potential synergistic effect on for development ESRD. We conducted this by using National Health Insurance Research Database Taiwan. recruited newly-diagnosed as cohort. A comparison cohort a 1:1 ratio...

Background Residual renal function (RRF) is pivotal to long-term outcomes, while rapid RRF decline (RRFD) associated with mortality risk for continuous ambulatory peritoneal dialysis (CAPD) patients. This study was conducted compare the impact of “initial anuria” and RRFD on prognosis CAPD Method According timing anuria slope RRFD, a total 255 incident patients were divided into 3 groups. For “anuria” group, detected from initiation persisted &gt; 6 months ( n = 27). Based median slope,...
