Purpose. Acute antibody-mediated rejection, a complication of cross match positive and sensitized renal transplants, occurs despite the use of standard desensitization protocols. Rescue therapy consists of plasmapheresis and intravenous immunoglobulin (IVIg). In patients with preformed donor specific antibodies, rejection can be aggressive. We report here a case in which laparoscopic splenectomy was added to the standard rescue regimen.Case Report and Results. A 40-year-old Hispanic female with end stage renal disease had been receiving hemodialysis. The patient had numerous class 1 unacceptable antigens. She was scheduled to undergo an incompatible 1-1-1 mismatch living related donor kidney transplant. Preoperatively, the patient received plasmapheresis, IVIG, and thymoglobulin. There was good graft function until postoperative day 5. At that point, worsening renal function was noted. Renal biopsy was consistent with AMR. The patient became anuric and dialysis was initiated. To salvage the transplant, the patient underwent laparoscopic splenectomy. Postoperatively, renal function improved. Two years after transplant, the patient continues to have excellent graft function.Conclusion. In a small but significant number of renal transplants, antibody production occurs at a rate that traditional treatments are unable to reduce effectively. Based on our experience, the addition of splenectomy to standard rescue therapy can salvage renal transplants.

Advanced atherosclerosis or thrombosis of iliac vessels can constitute an absolute contraindication for heterotopic kidney transplantation. We report the case of a 42-year-old women with end-stage renal disease due to lupus nephritis and a history of bilateral thrombosis of iliac arteries caused by antiphospholipid antibodies. Occlusion had been treated by the bilateral placement of wall stents which precluded vascular anastomosis. The patient was transplanted with a right kidney procured by laparoscopic nephrectomy from her HLA semi-identical sister. The recipient had left nephrectomy after laparoscopical transperitoneal dissection. The donor kidney was orthotopically transplanted with end-to-end anastomosis of graft vessels to native renal vessels and of the graft and native ureter. Although, the patient received full anticoagulation because of a cardiac valve and antiphospholipid antibodies, she had no postoperative complication in spite of a short period of delayed graft function. Serum creatinine levels three months after transplantation were at 1.0 mg/dl. Our case documents that orthotopical transplantation of laparoscopically procured living donor kidneys at the site of recipient nephrectomy is a feasible procedure in patients with surgical contraindication of standard heterotopic kidney transplantation.

Abstract Background and Aims Some kidney transplantation recipients with negative donor specific antibodies can develop acute rejection episodes which are difficult to treat, associated with non-HLA antibodies like angiotensin 2 type 1 receptor antibodies (AT1R Ab). The mechanism of rejection by AT1R ab involves vascular injury. Our cases are unique as the first patient got mineralocorticoid deficiency like picture unexpectedly. For the second case, hyperacute rejection cause in the first allograft was not identified and but hyperacute rejection episodes involving antibodies against endothelial cells are reported in literature. Method 2 patients received renal transplantation from life related donors in out institute developed acute rejection episodes. As part of investigations, we did non -HLA antibodies testing which came positive . Results Case 1 30 years old male, with end stage renal disease on hemodialysis . The patient had a live related renal transplant with Mismatch 1-1-1 and negative DSA. Induction with Basiliximab was initiated but changed to ATG due to delayed graft function. Kidney biopsy on day 6 post operatively showed diffuse moderate to severe acute tubular injury (up to necrosis) with glomerular intracapillary fibrin microthrombi, focal minimal peritubular capillaritis and mild glomerulitis and focal weak C4d positivity, highly suspicious for active antibody mediated rejection. The patient was treated with pulse steroids, ATG total of 7.5mg/kg, 3 sessions of Plasma exchange and IVIG 2 g/kg and 2 doses of Rituximab for his hyperacute rejection. AT1R antibodies titer was 11U/ml. MICA was negative. Losartan was initiated as a maintenance therapy.

Background: Calciphylaxis is a potentially fatal condition previously observed in patients with poor renal function. We present a case of atypical presentation in a patient with good renal function after transplantation. Case Presentation: A-68-year old African American female with history of end-stage renal disease (ESRD) secondary to type II diabetes mellitus on hemodialysis for ten years, status post living related donor kidney transplant from her son three years prior to this presentation, parathyroidectomy, and atrial fibrillation on warfarin presented to our institution with progressively worsening, severely tender bilateral thigh lesions that were diagnosed as calciphylaxis. She was treated with sodium thiosulfate infusions for six months and continues to do well. Conclusions: Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), has traditionally been associated with ESRD patients on maintenance dialysis, however several nonuremic cases of CUA have been reported in recent years. Multiple pathophysiologic mechanisms for CUA development have been proposed expanding the scope of known risk factors and possible triggers. CUA can be a life-threatening condition that is important for clinicians to recognize and treat as soon as possible.

Robotic surgery has enabled surgeons to offer more patients a minimally invasive surgical option in the management of their complex diseases. While renal transplantation is associated with significant improvements in quantity and quality of life for most end-stage renal disease (ESRD) patients, it is also not devoid of its surgical risks and potential morbidities. Robotic-assisted kidney transplantation is a recently described, innovative application of the robotic surgery platform, and early experiences suggest that it is associated with comparable graft function and lower rates of complications.Urinary tract obstruction, though less common than ESRD, can be a serious threat to renal function. Severe ureteric stricture disease can represent a clinically complex problem requiring major reconstructive surgery. Completely intra-corporeal robotic renal auto-transplantation is another innovative application of the robotic surgery platform and represents a significant advancement in urologic surgery. Initial reports of this procedure demonstrate safety, feasibility, and excellent renal function outcomes.

A 58-year-old woman with a prior radical cystectomy and ileal conduit underwent a living-related donor renal transplant for end-stage renal disease secondary to autoimmune glomerulonephritis. She subsequently developed an ischaemic stricture of the transplant ureter. A successful ureteropyelostomy was performed with the native right ureter anastomosed to the pelvis of the renal transplant. She presented to the emergency department 18 months later feeling unwell and with raised inflammatory markers. Imaging demonstrated a large soft tissue mass over the right psoas muscle and hydronephrosis of the native right kidney. A nephrostomy and nephrostogram of the native right kidney diagnosed a urine leak from the native right kidney and she underwent an open right native nephrectomy. She recovered well postoperatively and continues to have excellent graft function. Renal transplantation in an abnormal urinary tract carries a high risk of complications. A multidisciplinary team approach is essential in offering the most appropriate treatment and ensuring good graft function is preserved.

Abstract Background We evaluated the efficacy and safety of roxadustat vs. epoetin alfa for the treatment of chronic kidney disease (CKD) related anemia in patients new to dialysis. Methods This was a phase 3, open-label, epoetin alfa-controlled trial. Eligible adults were on hemodialysis/peritoneal dialysis for ≥2 weeks and ≤4 months before randomization and had mean hemoglobin ≤10.0 g/dL. Primary endpoints were mean hemoglobin (g/dL) change from baseline averaged over weeks 28–52 regardless of rescue therapy (non-inferiority criterion: lower limit of 95% CI for treatment difference > −0.75) and percentage of patients achieving a hemoglobin response between weeks 1–24 censored for rescue therapy (non-inferiority margin for between-group difference: −15%). Adverse events were monitored. Results The intention-to-treat population included patients randomized to roxadustat (n = 522) or epoetin alfa (n = 521). Mean (SD) hemoglobin changes from baseline averaged over weeks 28–52 were 2.57 (1.27) and 2.36 (1.21) in the roxadustat and epoetin alfa groups. Roxadustat was non-inferior (least-squares mean difference: 0.18 [95% CI: 0.08, 0.29]) to epoetin alfa. Percentages of patients with a hemoglobin response were 88.2% and 84.4% in the roxadustat and epoetin alfa groups. Roxadustat was non-inferior to epoetin alfa (treatment-group difference: 3.5% [95% CI: −0.7%, 7.7%]). Adverse event rates were comparable between treatment groups. Conclusions Roxadustat was efficacious for correcting and maintaining hemoglobin levels compared to epoetin alfa. Roxadustat had an acceptable safety profile.

Optimal Treatment Strategy

Kidney transplantation (KT) is considered an optimal treatment strategy for end-stage renal disease. But human leukocyte antigen-sensitized, ABO-incompatible and antibody-mediated rejection might be the alarming hurdles in KT. Therapeutic plasma exchange is the mainstay of the antibody reduction therapy for reducing autoantibody more effectively. Even in the treatment for highly sensitized patients, it has played an indispensable role. However, clinicians should tailor therapies to individual patient’s needs and multimodal treatment will bring better outcomes. Early diagnosis and precise treatment would reduce morbidity, mortality, and economic costs.

End Stage

Patients with end-stage renal disease (ESRD) experience higher rates of hospitalisation, cardiovascular events, and all-cause mortality and are more likely to require admission to the intensive care unit (ICU) than patients with normal renal function. Sepsis and cardiovascular diseases are the most common reasons for ICU admission. ICU mortality rates in patients requiring chronic hemodialysis are significantly higher than for patients without ESRD; however, dialysis patients have a better ICU outcome than those with acute kidney injury (AKI) requiring renal replacement therapy suggesting that factors other than loss of renal function contribute to their prognosis. Current evidence suggests, the longer-term outcomes after discharge from ICU may be favourable and that long-term dependence on dialysis should not prejudice against prompt referral or admission to ICU.
