Comparison of renal function following donor nephrectomy versus radical nephrectomy for renal tumor.

In this study, we compared renal function in patients after donor nephrectomy (DN) and radical nephrectomy (RN). We retrospectively reviewed 68 patients (mean follow-up 15 months), including 30 patients who had undergone DN and 38 patients who had undergone RN. The study was performed between April 2006 and July 2010 at a single institute. Patients were matched for age and co-morbidities (hypertension and diabetes mellitus). We calculated the estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease study group equation. Parameters studied included GFR (≥60 to 2.0 mg/dL), metabolic acidosis (serum bicarbonate 30 mg). There were no significant demographic differences between the two study groups. After a mean follow-up of 15 months, low eGFR (

In this study, we assessed effects of LPZ on adipocyte differentiation and function by using 3T3-L1 preadipocytes and HFD-induced obesity mice as an in vitro and in vivo model, respectively.Main methodsOil red O staining and intracellular triacylglycerol content were used to determine lipid accumulation. Glucose uptake was performed to measure mature adipocyte function. Expression of adipocyte genes was determined by qRT-PCR and immunoblotting.Key findingsLPZ has dual effects on differentiation of 3T3-L1 cells. At low concentrations, LPZ enhanced adipocyte differentiation via induction of PPARγ and C/EBPα, two ...

Huisman, Aletta E. SchutteAbstractPurposeGlobally, a detrimental shift in cardiovascular disease risk factors and a higher mortality level are reported in some black populations. The retinal microvasculature provides early insight into the pathogenesis of systemic vascular diseases, but it is unclear whether retinal vessel calibers and acute retinal vessel functional responses differ between young healthy black and white adults.MethodsW...

Cavero et  al.1 recently reported the frequency and severity of hypertension in a cohort of 55 patients with atypical hemolytic uremic syndrome (aHUS). A major complication of hemolytic uremic syndrome is hypertensive crisis related to juxtaglomerular ischemia and renin angiotensin system activation. However , hypertensive crisis has been also described as a cause of thrombotic microangiopathy because of endothelial shear stress. Despite the persistent incidence of hypertensive crisis in developed and developing countries,2 the pathophysiological mechanisms and treatment of hypertensive crisis–associa ted hemoly...

We thank El Karoui and colleagues for their comments.1 We think that both studies, theirs and ours,2,3 show that severe hypertension is a characteristic feature of atypical hemolytic uremic syndrome (aHUS). Even their patients classified as aHUS not associated with hypertensive emergencies had a median blood pressure of 154/90 mm  Hg, which would include hypertension grades 1-2, according to the 2018 European Society of Cardiology/European Society of Hypertension guidelines.4 Unlike in their study, we found a favorable effect of eculizumab also in patients with severe and malignant hypertension.

Changes in indices of mineral metabolism, bone protein expression, and bone turnover were assessed between pre – and post–renal transplant bone biopsies obtained 12 months apart. Circulating sclerostin and fibroblast growth factor 23 (FGF-23) levels decreased, and a low bone turnover state was highly prevalent on follow-up. In contrast, bone sclerostin expression increased, whereas FGF-23 bone expression was unchanged/decreased. These findings underscore the limitations of circulating biomarkers and the critical role of bone biopsy to understand osteocyte biology in chronic kidney disease–mineral bone disorder.

A 63-year-old man was admitted 2 months after a deceased-donor kidney transplantation with an acute rise of his creatinine from a baseline of 1.9 mg/dl to 3.7 mg/dl. The patient had received basiliximab induction, followed by maintenance with belatacept, mycophenolic acid, and steroids. Physical examination and an ultrasound of the kidney transplant were unremarkable. Kidney biopsy revealed Banff acute cellular rejection grade IIB. Belatacept was replaced with tacrolimus, and steroid pulse and rabbit antithymocyte globulin were administered.

A 36-year-old female recipient of simultaneous pancreas-kidney transplantation 2 months previously was admitted to the emergency room because of a fever of unknown origin. Physical examination was unremarkable. Klebsiella pneumoniae was isolated in urine culture and treated with ceftriaxone according to antibiogram. High-grade fever persisted despite the increase in antibiotic spectrum with meropenem. Blood cultures were negative (including mycobacteria), as were quantiferon, cytomegalovirus, BK virus, Epstein –Barr virus polymerase chain reaction, and Toxoplasma gondii serologies.

A 59-year-old woman presented with extreme thirst. She was a current smoker (35 pack-years) and had extensive peripheral vascular disease, including asymptomatic carotid artery stenosis. She had hypertension that was well regulated with a calcium channel blocker (nifedipine 30 mg once daily). Her thirst had become gradually worse over 6 months and was affecting her quality of life. During outpatient evaluation at a regional hospital, her thirst was accompanied by polydipsia and polyuria (both ∼6 l/d).
