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.

This is a rare case of Caroli's disease, diagnosed following renal transplantation in a patient with autosomal recessive polycystic kidneys. Despite advanced cystic transformation of the biliary tree with striking architectural changes, there was no evidence of portal hypertension or hepatic fibrosis. Moreover, the patient did not suffer a single episode of cholangitis, a most interesting feature of this case. Her clinical course was punctuated by repeated episodes of gastrointestinal and urinary tract infections with resistant organisms; but fortunately, she had no evidence of
septicemia
. Recurrent Salmonella gastroenteritis indicated a chronic carrier state with the dilated bile ducts possibly acting as a potential reservoir. This has significant implications considering the immune suppression associated with renal transplantation. In general, Caroli's disease is rare. Therefore, a high index of suspicion for the diagnosis of Caroli's disease is warranted especially in patients with
ARPKD
or ADPKD. Once confirmed, affected patients with end-stage renal disease such as our patient, should ideally undergo combined liver-kidney transplantation.

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.
