Atypical hemolytic uremic syndrome (aHUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia and kidney injury caused by a dysregulation of the alternative complement pathway.

We conducted a multicenter nonregistry study aimed at collecting clinical, laboratory and genetic information of patients with aHUS in Brazil. Demographic data, genetic findings, treatments and outcomes are presented.

Thirty-four patients were included, 62% were female and 67% were Caucasian. Half of the patients had the first manifestation of aHUS before the age of 18years (pediatric group). Among the 17 patients who had the first manifestation after the age of 18years (adult group), 6 were kidney transplant patients. Overall, 22 patients (65%) received plasma exchange/plasma infusion (PE/PI) and 31 patients (91%) received eculizumab. Eculizumab was started later in the adult group compared with the pediatric group. Two patients stopped dialysis after PE/PI and 19 patients stopped dialysis after eculizumab de
Low-molecular-weight heparins (LMWHs) are easily dialysable with high-flow membranes; however, it is not clear whether the LMWH dose should be adjusted according to the membrane type and dialysis technique. This study aimed to evaluate the influence of the dialyser on anticoagulation of the extracorporeal dialysis circuit.

Thirteen patients received the same dose of LMWH through the arterial port via three dialysis techniques high-flux haemodialysis (HF-HD), online haemodiafiltration (HDF) and expanded haemodialysis (HDx). All dialysis was performed under similar conditions duration, 4 h; blood flow, 400 mL/min; and dialysate flow, 500 mL/min. Antifactor Xa (aXa) activity and activated partial thromboplastin time (APTT) were measured before and after the dialysis. Clotting time of the vascular access site after haemodialysis, visual clotting score of the dialyser and any complications with the extracorporeal circuit or bleeding were registered.

Post-dialysis aXa activity in HF-HD (0.26 ± 0.02 U/mL) was significantly different from that in HDF (0.21 ± 0.02 U/mL, P = 0.024), and there was a trend in HDx (0.22 ± 0.01 U/mL, P = 0.05). APTT post-dialysis in HF-HD (30.5 ± 0.7 s) was significantly different from that in HDx (28.2 ± 0.64 s, P = 0.009) and HDF (28.8 ± 0.73 s, P = 0.009).

AXa activity in HDF was significantly lower than that in HF-HD, possibly because of more losses of LMWH through the dialyser. Given the higher anticoagulant loss in HDF and probably in HDx than in HF-HD, the enoxaparin dose administered may be adjusted according to the dialysis technique.

Following concerns regarding the emergence of
infection in 2010, we changed antibiotic prophylaxis in patients undergoing primary hip and knee arthroplasty from cefuroxime to flucloxacillin and single-dose (SD) gentamicin. A subsequent perceived increase in the incidence of post-operative acute kidney injury (AKI) led us to evaluate the AKI incidence between different prophylactic antibiotic regimes used at our centre.

We examined the incidence of AKI as defined by Kidney Disease Improving Global Outcomes criteria in 1588 patients undergoing primary hip or knee arthroplasty from January 2010 to January 2015. Patients received the following prophylactic antibiotic regimes 8 g flucloxacillin in four divided doses and SD gentamicin 1.5 mg/kg ideal body weight (IBW; maximum dose 120 mg;
 = 400), 8 g flucloxacillin alone in four divided doses (
 = 400), SD cefuroxime (
 = 400), triple-dose (TD) cefuroxime (
 = 188) and teicoplanin with SD gentamicin 1.5 mg/kg IBW (
 = 200).

The incidence of AKI was rates of AKI.
Non-traditional cardiovascular risk factors, including calcium and phosphate derangement, may play a role in mortality in renal transplant. The data regarding this effect are conflicting. Our aim was to assess the impact of calcium and phosphate derangements in the first 90 days post-transplant on allograft and recipient outcomes.

We performed a retrospective cohort review of all-adult, first renal transplants in the Republic of Ireland between 1999 and 2015. We divided patients into tertiles based on serum phosphate and calcium levels post-transplant. We assessed their effect on death-censored graft survival and all-cause mortality. We used Stata for statistical analysis and did survival analysis and spline curves to assess the association.

We included 1525 renal transplant recipients. Of the total, 86.3% had hypophosphataemia and 36.1% hypercalcaemia. Patients in the lowest phosphate tertile were younger, more likely female, had lower weight, more time on dialysis, received a kidney from a younger don these metabolic derangements. The calcium and phosphate levels exhibit no independent association with death-censored graft failure and mortality.Rhabdomyolysis is a common cause of acute kidney injury, featuring muscle pain, weakness and dark urine and concurrent laboratory evidence of elevated muscle enzymes and myoglobinuria. Rhabdomyolysis is often seen in elderly and frail patients following prolonged immobilization, for example after a fall, but a variety of other causes are also well-described. What is unknown to most physicians dealing with such patients is the fascinating history of rhabdomyolysis. Cases of probable rhabdomyolysis have been reported since biblical times and during antiquity, often in the context of poisoning. Equally interesting is the link between rhabdomyolysis and armed conflict during the 20th century. Salient discoveries regarding the pathophysiology, diagnosis and treatment were made during the two world wars and in their aftermath. 'Haff disease', a form of rhabdomyolysis first described in 1920, has fascinated scientists and physicians alike, but the marine toxin causing it remains enigmatic even today. https://www.selleckchem.com/products/ibmx.html As a specialty, we have also learned a lot about the disease from 20th-century earthquakes, and networks of international help and cooperation have emerged.
