NODAT is increasingly prevalent. Compared with adult recipients, NODAT is less prevalent in pediatric renal transplant recipients; however, some risk factors for its development in young patients have been defined. We report four pediatric renal transplant recipients with ARPKD who developed NODAT. We review the current pediatric NODAT literature and hypothesize that ARPKD may be an additional risk factor for NODAT. 相似文献

Improved neonatal medical care and renal replacement technology have improved the long‐term survival of patients with ARPKD. Ten‐yr survival of those surviving the first year of life is reported to be 82% and is continuing to improve further. However, despite increases in overall survival and improved treatment of systemic hypertension and other complications of their renal disease, nearly 50% of survivors will develop ESRD within the first decade of life. In addition to renal pathology, patients with ARPKD develop ductal plate malformations with cystic dilation of intra‐ and extrahepatic bile ducts resulting in CHF and Caroli syndrome. Many patients with CHF will develop portal hypertension with resulting esophageal varices, splenomegaly, hypersplenism, protein losing enteropathy, and gastrointestinal bleeding. Management of portal hypertension may require EBL of esophageal varices or porto‐systemic shunting. Complications of hepatic involvement can include ascending cholangitis, cholestasis with malabsorption of fat‐soluble vitamins, and rarely benign or malignant liver tumors. Patients with ARPKD who eventually reach ESRD, and ultimately require kidney transplantation, present a unique set of complications related to their underlying hepato‐biliary disease. In this review, we focus on new approaches to these challenging patients, including the indications for liver transplantation in ARPKD patients with severe chronic kidney disease awaiting kidney transplant. While survival in patients with ARPKD and isolated kidney transplant is comparable to that of age‐matched pediatric patients who have received kidney transplants due to other primary renal diseases, 64–80% of the mortality occurring in ARPKD kidney transplant patients is attributed to cholangitis/sepsis, which is related to their hepato‐biliary disease. Recent data demonstrate that surgical mortality among pediatric liver transplant recipients is decreased to <10% at one yr. The immunosuppressive regimen used for kidney transplant recipients is adequate for most liver transplant recipients. We therefore suggest that in a select group of ARPKD patients with recurrent cholangitis or complications of portal hypertension, combined liver–kidney transplant is a viable option. Although further study is necessary to confirm our approach, we believe that combined liver–kidney transplantation can potentially decrease overall mortality and morbidity in carefully selected ARPKD patients with ESRD and clinically significant CHF. 相似文献

Autosomal recessive polycystic kidney disease (ARPKD) is characterized by dilation of ectatic renal collecting ducts, intrahepatic biliary dysgenesis, and portal fibrosis. Portal hypertension and recurrent bacterial cholangitis can dominate the clinical picture in long-term survivors. Predominant extrahepatic bile duct disease was revealed in four patients who underwent magnetic resonance cholangiopancreatography. All four patients had portal hypertension, although liver biochemistries did not suggest biliary disease. In two of the patients, cholangitis was clinically ascribed to the bile duct disease. Western blot analysis of plasma membranes from normal rat extrahepatic bile duct and kidney revealed the presence of polyductin as a single approximately 440 kDa protein. Although the exact function of polyductin in the extrahepatic duct is unknown, it may have a role in the development and control of lumenal size. Clinical management of patients with ARPKD should include consideration of potential problems related to extrahepatic bile duct disease. 相似文献

Autosomal recessive polycystic kidney disease (ARPKD) is the most common pediatric renal cystic disease with liver involvement. The vast majority of patients with ARPKD carry mutations in the recently characterized PKHD1 gene on chromosome 6p12. A Turkish female demonstrated rapid growth of both kidneys after delivery. Accelerated growth of both kidneys and increasing respiratory distress necessitated right-sided nephrectomy at the age of three months. Because of persistent dyspnea and ongoing growth of the remaining kidney, the second kidney also had to be removed one month later. Biopsies taken from the kidney and the liver confirmed the diagnosis of ARPKD histologically. Renal ultrasound of the patient's consanguineous parents and her older brother showed normal results. PKHD1 mutation analysis yielded a novel homozygous missense mutation (c.1116C >G, F372L) in exon 14, coding for an Ig-like domain (TIG), possibly involved in the increased growth of the kidneys. Peritoneal dialysis was performed for 12 months. The patient had successful transplantation at the age of 15 months and is doing well with actual immunosuppression with cyclosporine, mycophenolate mofetil, and prednisolone. In conclusion, the present case clearly demonstrates the favorable outcome of a child with severe ARPKD after bilateral nephrectomy, pre-emptive dialysis, and successful transplantation. 相似文献

Congenital hepatic fibrosis (CHF) is an uncommon autosomal recessive malformation. It may be associated with extrahepatic manifestations such as polycystic kidney disease. The main consequence is portal hypertension and bleeding from varices. Despite liver transplantation as a therapeutic option for this patient, long-term impact of liver transplantation on renal functions of patients with autosomal recessive polycystic kidney disease with associated liver disease is not well known. In this study, we aimed to analyze the patient's renal function after liver transplantation by creatinine clearance, glomerular filtration rate, and renal resistive indexes. Between March 1997 and September 2002, three of 50 orthotopic liver transplantation (OLT) were performed because of CHF associated with ARPKD at Ege University Organ Transplantation and Research Center. Baseline immunosuppression consisted of prednisone and cyclosporine A (CSA). The mean follow-up of the patients was 2.1 yr. Blood urea and creatinine levels were decreased after operation in all patients and remained within the normal range at the sixth and 12th month, whereas the level of the third patient were increased at the 18th month. RRI values of patients were not found different at the sixth month whereas, RRI values of patients were decreased at the 12th month and remained unchanged at the 18th month of follow-up. During the study period hypertension developed in one patient at the 16th month and resolved with antihypertensive treatment and decreasing dosage of CSA. Kidney function has remained satisfactory in all of the patients despite the use of cyclosporine. OLT can provide good survival in patients with CHF associated with ARPKD. 相似文献

CLKT and sequential KALT are decided on a case‐by‐case basis in children for special indications such as ARPKD or PH1. We report on 21 children who underwent CLKT or KALT at our hospital between 1998 and 2013. Eleven children were diagnosed with PH1 and six with ARPKD. Other diagnosis were Joubert syndrome (n = 1), nephronophthisis (n = 1), CF (n = 1), and hepatocellular carcinoma (n = 1). Children (12 males, nine females) were aged 7.8 ± 6.2 yr (range, 10 months to 18 yr) at time of transplantation. Average wait time was 1.9 ± 0.9 yr (range, four months to 2.3 yr). Fifteen patients received dialysis prior to transplantation. In PH1 patients, four children received CLKT, five received KALT, and two infants have received only an LTx, whereas all six patients with ARPKD received CLKT. In patients with other indications, CLKT was performed in three cases and KALT in one girl. Cumulative 10‐yr survival of all 21 patients was 78.4%. At the time of transfer into adult care, 13 patients retained stable liver and kidney function. Regardless the underlying diagnosis, CLKT and KALT can be performed in children with good surgical outcomes and long‐term survival. 相似文献

Survival of childhood polycystic kidney disease following renal transplantation: the impact of advanced hepatobiliary disease 总被引:2,自引:0,他引:2
Childhood PKD encompasses the diagnoses of AR and ADPKD, glomerulocystic disease, and syndromes such as tuberous sclerosis or Jeune's syndrome. Given the fact that a majority of PKD children with ESRD carry the diagnosis of ARPKD, natural history studies assessing the long-term prognosis of PKD patients following renal transplantation must focus on morbidity and mortality issues related to complications from congenital hepatic fibrosis. Using the NAPRTCS registry, we analyzed the patient and graft survival rates of 203 PKD patients and 7044 non-PKD patients undergoing renal transplantation between 1987 and 2001. Deceased PKD patients, all with a diagnosis of ARPKD, were further identified and characterized using a special questionnaire submitted to the principal investigators. Overall graft and patient survival rates were not significantly different between PKD and non-PKD patients. No differences in rates of acute rejection or time to first rejection were noted between PKD and non-PKD patients. The relative risk of living longer than 3 yr in the PKD patients was not significantly different from non-PKD patients (RR = 0.70, p = 0.28). Sepsis was identified as a likely factor in the cause of death in nine (64%) ARPKD patients and was comfirmed with a positive blood culture in four patients. Despite similar graft and patient survival rates among PKD and non-PKD children following renal transplantation, our results suggest that ARPKD transplant recipients appear to be at increased risk for sepsis that may be related to hepatic fibrosis and ascending cholangitis. The utility of early liver transplantation in ARPKD patients with significant hepatobiliary disease is discussed. 相似文献

The natural history and survival of children with fibrocystic liver–kidney disease undergoing solid organ transplantation have infrequently been described. We report outcomes in a cohort of US children with fibrocystic liver–kidney disease receiving solid organ transplants over 20 yr. Retrospective cohort study of pediatric transplant recipients with diagnoses of fibrocystic liver–kidney disease from 1/1990 to 3/2010, using data from the SRTR. Subjects were categorized by the first transplanted organ: LT, KT, or SLK. Primary outcomes were death, re‐transplant, transplant of the alternate organ, or initiation of dialysis. Seven hundred and sixteen subjects were transplanted in this period. Median age at first transplant was 9.7 yr. Of the LT, 14 (19%) required a second liver transplant at median of 0.2 yr, and five (7%) required kidney transplant or dialysis at a median of 9.0 yr. Of the KT, 188 (31%) required a second kidney transplant or dialysis at a median of 5.9 yr. Twenty‐nine (5%) subsequently received liver transplant at a median of 6.0 yr. Among patients in this registry, far more children underwent kidney than liver transplants. The risk of subsequently needing transplantation of an alternate organ was low. 相似文献

ARPKD/CHF is an inherited disease characterized by non-obstructive fusiform dilatation of the renal collecting ducts leading
to enlarged spongiform kidneys and ductal plate malformation of the liver resulting in congenital hepatic fibrosis. ARPKD/CHF
has a broad spectrum of clinical presentations involving the kidney and liver. Imaging plays an important role in the diagnosis
and follow-up of ARPKD/CHF. Combined use of conventional and high-resolution US with MR cholangiography in ARPKD/CHF patients
allows detailed definition of the extent of kidney and hepatobiliary manifestations without requiring ionizing radiation and
contrast agents. 相似文献

Background
There are several clinical reports about the co-occurrence of autosomal dominant polycystic kidney disease (ADPKD) and connective tissue disorders. A simultaneous occurrence of osteogenesis imperfecta (OI) type I and ADPKD has not been observed so far.Methods
This report presents the first patient with OI type I and ADPKD.Results
Mutational analysis of PKD1 and COL1A1 in the index patient revealed a heterozygous mutation in each of the two genes. Mutational analysis of the parents indicated the mother as a carrier of the PKD1 mutation and the father as a carrier of the COL1A1 mutation. The simultaneous occurrence of both disorders has an estimated frequency of 3.5:100 000 000.Conclusion
In singular cases, ADPKD can occur in combination with other rare disorders, e.g. connective tissue disorders.13.

Moyamoya disease is a chronic cerebrovascular disorder with progressive stenosis. We describe a four‐yr‐old female with features of moyamoya disease referred to our center for kidney transplant evaluation with ESRD secondary to presumed renal dysplasia along with concern for cerebral vascular anomalies. With her constellation of organ involvement, a genetic workup revealed a homozygous, frameshift mutation in the mitochondrial methionyl‐tRNA formyltransferase gene. Given her vascular anomalies and evidence of prior infarcts seen on cerebral imaging, it was felt that her risk of future stroke events was high and that hypotension or intravascular volume depletion would further exacerbate this risk. In hopes of improving her tenuous cerebral perfusion, she underwent a bilateral temporal craniotomy for superficial temporal artery to middle cerebral artery bypass. We highlight the challenges faced in a child with ESRD and kidney transplantation when cerebral vasculature is compromised. A multidisciplinary approach is critical in determining the need for a revascularization procedure prior to transplant and to help reduce the risk of ischemic or hemorrhagic events in this patient population. 相似文献

Autosomal recessive polycystic kidney disease in 115 children: clinical presentation, course and influence of gender 总被引:5,自引:0,他引:5

The clinical course of 66 boys and 49 girls with autosomal recessive polycystic kidney disease recruited from departments of paediatric nephrology was investigated over a mean observation period of 4.92 years. This is a selected study group of children from departments of paediatric nephrology who in most cases survived the neonatal period, since birth clinics did not participate. The median age at diagnosis was 29 days (prenatal to 14.5 years). We observed decreased glomerular filtration rates (GFRs) in 72% (median age at onset of decrease of GFR < 2SD, 0.6 years; range. 0-18.7 years), and 11 patients developed end-stage renal disease. Hypertension requiring drug treatment was found in 70% (median age at start of medication, 0.5 years; range, 0-16.7 years). Kidney length was above the 97th centile in 68% of patients, and kidney length did not increase with age or deterioration of renal function. Urinary tract infections occurred in 30%, growth retardation in 25%. and clinical signs of hepatic fibrosis were detected in 46%. Thirteen patients (11 %) died during the observation period. 10 of them in the first year of life. There was a statistically significant sex difference in terms of a more pronounced progression in girls. The survival probability at 1 year was 94% for male patients and 82'% for female patients ( p < 0.05) in this study. Urinary tract infections occurred more frequently in girls ( p < 0.025) and were observed earlier. In addition, more girls had impaired renal function. developed end-stage renal disease and showed growth retardation; these differences, however. were not significant. For the children in this study, however, our results indicate that the long-term prognosis in the majority of cases is better throughout childhood and youth than often stated. 相似文献

In patients with autosomal dominant polycystic kidney disease (ADPKD), intracranial aneurysms (ICAs) are extrarenal manifestations and may result in serious and potentially fatal outcome following rupture. Although ICAs are a well-known complication of ADPKD, nearly all cases of ICA occurring in the context of ADPKD are adults. Here, we report the case of a Japanese girl with ADPKD who developed a subarachnoid haemorrhage (SAH) due to a ruptured ICA at the age of 4 years. Conclusion:This report is intended to raise awareness that the use of noninvasive screening techniques such as three-dimensional CT angiography or magnetic resonance angiography to detect intracranial aneurysms should also be performed in paediatric patients with autosomal dominant polycystic kidney disease. 相似文献

We analysed the body growth of 121 prepubertal children with polycystic kidney disease participating in a longitudinal multicentre study. The patients were followed from an age of 1 to 9 years in girls and 1 to 10 years in boys over a mean period of 3.6 years. Children with end-stage renal disease were excluded. Fifty-four patients had the autosomal dominant form of the disease and 67 the autosomal recessive form. At last observation, 2% of patients with the dominant form and 28% of those with the recessive form had an estimated glomerular filtration rate of < 60 ml/(min 1.73 m2 ). At first observation, the mean height SD score (SDS) in patients with the dominant form was almost the same as in controls, whilst in those with the recessive form it was significantly decreased (girls –0.82 SDS, boys -0.68 SDS, p < 0.001). During the follow-up the height SDS decreased slightly in both groups (NS). In patients with autosomal recessive kidney disease the degree of growth retardation appeared to be related to renal function: at last observation the height of girls with an estimated glomerular filtration rate of < 60ml/(min 1.73 m2 ) was more retarded than that of boys (mean -2.1 SDS versus -1.5 SDS, NS). The height SDS and renal function at last observation correlated in girls ( r = 0.83, p < 0.001) but not in boys ( r = 0.55) with the recessive form. No correlation was found between the height SDS and hypertension. The weight-for-height SDS at onset was significantly reduced in patients with the recessive form with decreased renal function. Our data suggest that the autosomal recessive, but not the dominant, form of polycystic kidney disease is associated with early growth retardation, which seems to be more severe in girls, probably due to the more rapid deterioration of renal function. 相似文献

Autosomal-recessive polycystic kidney disease (ARPKD) can cause renal failure and portal hypertension in children. Portal hypertension may complicate the course of renal transplantation (Tx). We report the successful outcome of a patient with end-stage renal disease (ESRD) and portal hypertension treated with transjugular intrahepatic portosystemic shunt (TIPS), a minimally invasive endovascular technique of portosystemic shunt, prior to renal Tx. 相似文献
