Requiring Hemodialysis (requiring + hemodialysis)
Selected AbstractsReactions to Penicillamine: A Case of Cutis Laxa, Elastosis Perforans Serpiginosa and "Pseudo" PseudoxanthomaJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2005S. Frankel This patient was a 61-year-old white female who received several years of penicillamine therapy for the treatment of cystinuria. She subsequently developed penicillamine induced cutis laxa, elastosis perforans serpiginosa, and pseudoxanthoma elasticum like skin lesions. In addition, she suffered from numerous chronic bilateral lower extremity skin ulcerations. Her past medical history was also significant for end stage renal disease requiring hemodialysis and pulmonary fibrosis. She presented to the University of Miami Wound Care Center in 1/04 for treatment of her chronic ulcerations. On physical examination, the patient had multiple large hyperpigmented plaques with central ulcerations on her lower extremities. Some of the ulcers had overlying crust and others were covered with yellow fibrinous tissue. She also had generalized thickened, lax skin with multiple folds. On her neck, thighs, back and arms were violaceous, atrophic, serpiginous plaques with peripheral crusted erosions. A biopsy taken from the patients left thigh revealed dermal elastosis and the features of pseudo-pseudoxanthoma. Two additional biopsies taken from the left thigh demonstrated elastosis perforans serpiginosa. This case highlights multiple skin manifestations of penicillamine therapy. [source] Living liver donor death related to complications of myelomaLIVER TRANSPLANTATION, Issue 3 2009Emmanuel Melloul We report a donor death after right hepatectomy for living donor transplantation due to an undiagnosed myeloma. The 47-year-old donor, who was the 147th case performed in our department, was in excellent health without any abnormalities in the preoperative investigations. Despite an uneventful right hepatectomy without transfusion, the patient developed a partial thrombus of the inferior vena cava with a right proximal pulmonary trunk embolism on postoperative day 6. Subsequently, he developed multiorgan dysfunction leading to a coagulopathy, respiratory distress, and renal failure requiring hemodialysis and mechanical ventilation. This clinical scenario led us to suspect a hematological disorder. Immune electrophoresis showed a monoclonal peak of immunoglobulin G (8.7 g/L), a myelogram revealed an abnormally high level of dystrophic plasmocytes (more than 7%), and biopsies of salivary glands confirmed the diagnosis of immunoglobulin G kappa myeloma. The patient progressively deteriorated because of simultaneous hemorrhagic and infectious pulmonary complications resulting in septic shock. Despite an adequate combination of antimicrobial therapy and pleural drainage, the donor died on postoperative day 57 from multiple organ failure. This unusual cause of donor death after right hepatectomy reinforces the need for an extensive preoperative assessment. We advocate the addition of urinary protein loss and electrophoresis to the standard donor assessment protocol. Liver Transpl 15:326,329, 2009. © 2009 AASLD. [source] Renal Failure Five Years After Lung Transplantation Due to Polyomavirus BK-Associated NephropathyAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2010A. Egli Polyomavirus-associated nephropathy (PyVAN) is rare in nonrenal solid organ transplantation and only limited information is available from single cases. We describe a 67-year-old female presenting with hypertension and progressive kidney failure due to PyVAN 60 months after lung transplantation. Plasma BK virus (BKV) loads were 4.85 log10 copies/mL at diagnosis and cleared slowly over 14 months after switching from tacrolimus, mycophenolate and prednisone to low-dose tacrolimus, sirolimus and leflunomide, the latter being discontinued for anemia and diarrhea. BKV- and JC virus-specific immunoglobulins were detectable prior to transplantation. Only BKV-specific IgG and IgM increased during follow-up. BKV-specific T cells were detectable in blood following in vitro expansion, but cleared with reincreased sirolimus, yet BKV viremia remained undetectable. We identified eight other cases of PyVAN in nonrenal solid organ transplantation including lung (n = 1), heart (n = 6) and pancreas (n = 1). Overall, diagnosis was later than commonly seen in kidney transplants (median 18 months, interquartile range 10,29). Seven patients were male, five received triple immunosuppression consisting of tacrolimus, mycophenolate, prednisone. Immunosuppression was reduced in four cases and cidofovir and/or leflunomide administered in five and two cases, respectively. Renal function deteriorated in five requiring hemodialysis in four. We discuss mTOR inhibitors versus cidofovir and leflunomide as potential PyVAN rescue therapy. [source] Deceased Donor Kidney Transplantation from Donors with Acute Renal Failure due to RhabdomyolysisAMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2009K. L. Mekeel With the current shortage of solid organs for transplant, the transplant community continues to look for ways to increase the number of organ donors, including extending the criteria for donation. In rhabdomyolysis, the byproducts of skeletal muscle breakdown leak into the circulation resulting in acute renal failure in up to 30% of patients. In nonbrain dead patients, this condition is reversible and most patients recover full renal function. Seven potential donors had rhabdomyolysis with acute renal failure as evidenced by the presence of urine hemoglobin, plasma creatinine kinase levels of greater than five times the normal and elevated creatinine. One donor required dialysis. At our institution, 10 kidneys were transplanted from the seven donors. Two grafts had immediate function, five grafts experienced slow graft function and three grafts had delayed graft function requiring hemodialysis. At a mean of 8.7 months posttransplant (2.4,25.2 months), all patients have good graft function, are off dialysis and have a mean creatinine of 1.3 (0.7,1.8). In conclusion, our experience suggests that rhabdomyolysis with acute renal failure should not be a contraindication for donation, although recipients may experience slow or delayed graft function. [source] Extracorporeal Life Support: A Simple and Effective Weapon for Postcardiotomy Right Ventricular FailureARTIFICIAL ORGANS, Issue 7 2009Kuo-Sheng Liu Abstract Postcardiotomy right ventricular (RV) failure develops during the perioperative period following pulmonary hypertensive crisis or acute myocardial infarction. This study reports our institutional experience in treating these patients with extracorporeal life support (ECLS). Between June 2002 and July 2005, 46 adults were treated with ECLS for postcardiotomy shock. Acute RV failure was the cause of support in 14 (30%). Patient mean age was 55.7 ± 15.4 years. Cardiac pathologies were valvular (n = 7), coronary (n = 1), combined coronary and valvular disease (n = 2), complex congenital heart (n = 2), aortic aneurysm (n = 1), and cardiomyopathy post heart transplant (n = 1). The triggers of RV failure were pulmonary hypertension (n = 6), RV infarction (n = 4), and not defined (n = 4). Patients were supported on ECLS for a mean duration of 71 ± 52 h (range, 10,183 h). Major complications included acute renal failure requiring hemodialysis (n = 4), reexploration for bleeding (n = 2), and acute subdural hematoma (n = 1). Nine (64%) patients were successfully weaned from ECLS, and seven (50%) survived to discharge. Preexisting pulmonary hypertension had a favorable tendency for weaning, and acute renal failure requiring hemodialysis correlated with in-hospital mortality. ECLS is beneficial for treating postcardiotomy RV failure when conventional therapy is exhausted. As it can be deployed rapidly and does not require resternotomy for weaning, ECLS could be regarded as the first choice of mechanical support for postcardiotomy RV failure. [source] | ||||||||||
