We present a rare case of pancreatic panniculitis in a 59‐year‐old male simultaneous pancreas–kidney (SPK) recipient with failed allografts. The patient presented with fever and painful erythematous nodules on his leg 1 month after stopping all immunosuppression. A thorough infectious and rheumatological workup was negative. He had pancreas rejection 4 years after SKP transplant and was restarted on dialysis after 14 years when his renal allograft failed due to chronic allograft nephropathy. His chronic immunosuppression (tacrolimus, azathioprine) was stopped and prednisone was weaned over 3 months at that time. A skin biopsy revealed saponification of the subcutaneous fat with inflammation pathognomonic of pancreatic panniculitis. Concurrent allograft pancreatitis confirmed with elevated lipase and a computed tomography scan finding of peripancreatic graft stranding and atrophic native pancreas. He was started on pulse steroid therapy for 3 days followed by oral taper. This resulted in dramatic resolution of all skin lesions and normalization of lipase levels within 1 week, followed by resumption of low‐dose tacrolimus and azathioprine. This is an extremely rare occurrence of panniculitis in pancreas allograft after 10 years of pancreatic failure associated with stopping immunosuppression. 相似文献

Pancreas transplantation is still the best option to achieve normoglycaemia and insulin independence in patients with type I diabetes. As a result of improvements in surgical techniques, immunosuppression and patient selection, one year survival rates of 95, 83, and 88% for patient, pancreas, and kidney survival, respectively, are reported for patients with simultaneous pancreas and kidney transplantation. The main goals for the future are to reduce postoperative morbidity, to identify the relevant indications for single pancreas transplantation, to adopt the best surgical technique for individual patients' needs (bladder versus enteric drainage with or without portal venous delivery of insulin), and to develop immunosuppressive strategies with low nephrotoxic and diabetogenic potential. 相似文献

The objective of this study was to evaluate the outcome of simultaneous pancreas and kidney transplantation (SPK) with focus on cardiovascular mortality and morbidity in relation to graft function. From January 1985 through 1999, 87 SPK were performed in the unit. Sixty recipients were males, median age at diabetes onset 13 yr (1-40) and age at transplantation 39 yr (29-54). No case was lost to follow-up. Morbidity and mortality during median 8 yr of follow-up (range 1-15 yr) were recorded. Major macrovascular disease (MVD) was defined as myocardial infarction or sudden death (AMI), stroke or peripheral gangrene requiring amputation of leg, foot or fingers. At the evaluation, 26 of 87 patients (30%) had died, 19 after loss of the pancreas graft and 20 after loss of the kidney. MVD was the dominant cause of death. Non-lethal MVD had previously been recorded in 62%. Of the 61 patients alive, 22 had lost their pancreas graft and 12 the concomitant kidney. MVD had occurred in 32%. Whereas 89% of the concomitant kidneys functioned when the pancreas graft did so, only 37% of the kidneys functioned if the pancreas had been lost, p < 0.0001. The mortality rate was significantly higher among patients who lost both grafts (16/26) than in those who lost only the pancreas graft (3/15), p = 0.01. Progressive MVD is a major clinical problem for SPK transplant patients, particularly if the kidney fails. 相似文献

It has been shown that lipid profiles do not differ between pancreas recipients with systemic and portal venous anastomosis. However, it is unclear whether venous drainage from the transplanted pancreas has an impact on recipient atherogenesis and if other factors should be considered. Increased concentration of proinsulin correlates with tachycardia and other risk factors for ischemic heart disease. The aim of this study was to compare proinsulin levels in different types of pancreatic graft venous drainage. Twenty-four simultaneous pancreas and kidney transplantation (SPK) recipients with systemic venous drainage (group S, n = 12) and portal venous drainage (group P, n = 12) under identical immunosuppressive treatment were prospectively observed during 24 months. Following transplantation, only recipients with normoglycemia, normal HbA1c, and normal serum creatine were evaluated. Proinsulin was assessed in fasting state; after glucagon stimulation (Delta-proinsulin), and during oral 75-g glucose tolerance test twice: between 3 and 6 months and 12 to 24 months posttransplantation. All SPK patients had higher proinsulin concentration in fasting state compared with age-matched healthy controls. After stimulation, proinsulin level did not significantly differ between groups; the type of the pancreas venous anastomosis did not change the release of proinsulin and should not have impact on cardiovascular risk factors. 相似文献

We report the case of a simultaneous kidney and pancreas transplant recipient who presented with vague neurologic symptoms 21 months following the surgery. Computed tomography, magnetic resonance imaging, and fundoscopy findings were normal. Serology titers for antitoxoplasmic antibodies were increased. This was an atypical presentation of toxoplasmosis in a simultaneous kidney and pancreas transplant patient. 相似文献

BACKGROUND: Although technical success rate of simultaneous pancreas kidney
(SPK) transplantation in insulin-dependent diabetes mellitus (IDDM)
patients with diabetic nephropathy has improved, morbidity remains high due
to infection and rejection. The purpose of this study was to analyse
infections encountered in our series of SPK transplants, using a
restrictive antibiotic prophylaxis policy. METHODS: We reviewed all
infectious diseases after 66 consecutive bladder-drained SPK
transplantations in 64 IDDM patients with end-stage renal disease due to
diabetic nephropathy. During follow-up, the perioperative antibiotic
regimen was altered (from 5 days preemptive therapy with multiple drugs to
1 day prophylaxis with cefamandole), and long-term viral prophylaxis
(high-dose aciclovir) was introduced. For post-operative urinary tract or
opportunistic infection, no prophylaxis was given. RESULTS: Overall mean
infection rate was 2.9 infections/ patient/year after a mean follow-up of
2.3 years. Surgical site infections (SSI) were seen in 30% of the patients,
with Enterococci present in 47%. Logistic regression showed one day
cefamandole prophylaxis to be associated with SSI, but there was no
significant influence of SSI on either graft or patient survival.
Forty-eight percent of all infections were lower urinary tract infections
(UTI). There were 59 first UTIs (89%), probably related to long-term Foley
catheter use, and 47 second UTIs (71%). Subsequent UTIs were not
microbiologically related to first UTIs. Cytomegalovirus (10 patients) and
other opportunistic agents did not cause mortality or graft loss. Five
grafts were lost due to infection (SSI three times, post-transplant
lymphoproliferative disease twice). Only one patient died because of
infection (2%). CONCLUSIONS: Infectious diseases after SPK transplantation
caused significant morbidity but did not influence either patient or graft
survival. A change in prophylactic policy for both SSI as well as recurrent
UTI, combined with earlier Foley removal, may lower incidences of these
infections.

Isolated failure of the renal graft after simultaneous kidney-pancreas transplantation (SPK) is a rare but potential outcome. Many of these patients are candidates for kidney retransplantation. This paper describes a series of 3 patients who underwent successful kidney retransplantation after SPK. The operation was completed through an extraperitoneal incision without disruption of the pancreas graft or need for a transplant nephrectomy. 相似文献

Dissection of the external iliac artery is a rare but serious complication after transplantation, leading to graft loss. Stent angioplasty has been accepted for iliac artery dissection, but the safety and benefits of this procedure in transplantation are unclear. We report a case of right external iliac artery dissection with simultaneous kidney and pancreas transplantation, which was noticed during the operation. A self-expandable metallic stent was inserted from the right femoral artery to the dissected area and arterial blood flow was immediately restored. The postoperative clinical course was uneventful and soon after transplantation both the kidney and pancreas graft functioned well. Together with a previously reported six cases of stent replacement with transplantation and our case, no complication related to this procedure was reported, and in six cases the arterial flow was restored and graft function was improved. Endovascular stent replacement may be a safe and effective procedure for iliac artery dissection in transplantation. 相似文献
