Abstract
Combined liver-kidney transplantation (CLKT) is a surgical procedure that involves transplanting both liver and kidney organs. There are two types of CLKT: simultaneous liver-kidney transplantation (smLKT) and sequential LKT (sqLKT). CLKT accounts for a small percentage of liver transplantations (LTs), particularly in pediatric cases. Nevertheless, the procedure has demonstrated excellent outcomes, with high survival rates and lower rejection rates. The main indications for CLKT in pediatric patients differ somewhat from that in adults, in which end-stage kidney disease after LT is the major indication. In children, congenital diseases are common reason for performing CLKT; the examples of such diseases include autosomal recessive polycystic kidney disease with congenital hepatic fibrosis which equally affects both organs, and primary hyperoxaluria type 1, a primary liver disease leading kidney failure. The decision between smLKT or sqLKT depends on the dominant organ failure, the specific pathophysiology, and available organ sources. However, there remain significant surgical and societal challenges surrounding CLKT. Innovations in pharmacology and genetic engineering have decreased the necessity for CLKT in early-diagnosed cases without portal hypertension or kidney replacement therapy. Nonetheless, these advancements are not universally accessible. Therefore, decision-making algorithms should be crafted, considering region-specific organ allocation systems and prevailing medical environments.

Acharya R, Upadhyay K. Short-Term Outcome of Isolated Kidney Transplantation in Children with Autosomal Recessive Polycystic Kidney Disease: A Case Series and Literature Review. Clin Pract 2023; 14:24-30. [PMID: 38300123 PMCID: PMC10887803 DOI: 10.3390/clinpract14010003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 12/18/2023] [Accepted: 12/20/2023] [Indexed: 02/02/2024] Open
Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is often associated with hepatobiliary disease in the form of hepatic fibrosis and/or Caroli disease. Combined liver-kidney transplantation (CLKT) is a transplant modality of choice in children with both end-stage renal disease (ESRD) and severe hepatic disease. However, there is no consensus on whether children with ARPKD-associated ESRD without severe hepatic disease can be treated with isolated kidney transplantation (KT) without the need for CLKT. We retrospectively studied the efficacy of isolated KT in children with ARPKD without severe hepatic disease, and followed the course of hepatic disease post KT. This is a single-center study of three children with ARPKD and ESRD who underwent isolated KT. None of them had severe hepatic disease at the time of KT. All children were clinically diagnosed with ARPKD in the immediate postnatal period. All had hepatic fibrosis of varying degrees and two had intrahepatic biliary duct (IHBD) dilatation. None had gastrointestinal (GI) bleed, portal hypertension or cholangitis. Two children had preemptive KT. Pre-transplant unilateral or bilateral native nephrectomy were performed for two children, and one underwent unilateral native nephrectomy at the time of KT. The median creatinine clearance at a median post-KT follow-up of 24 months was 60.3 mL/min/1.73 m2. The two-year graft and patient survival were both 100%. Post KT, all three patients continued to demonstrate evidence of hepatic fibrosis and IHBD on sonogram; however, none of them were either evaluated for or required liver transplantation given normal synthetic liver function and absence of portal hypertension or other severe hepatobiliary disease. There were no adverse events observed such as cholangitis, GI bleed, or multiorgan failure. Hence, an excellent short-term graft and patient survival was demonstrated in this study of children with ARPKD and mild to moderate hepatic disease who received isolated KT. Long-term follow-up and larger studies are important to assess the efficacy of isolated KT in this subset of children with ARPKD.

Abstract
Rare liver diseases caused by ductal plate malformation, such as congenital hepatic fibrosis (CHF), Caroli syndrome, and polycystic liver disease, can have clinical manifestations such as recurrent cholangitis—frequently involving multidrug-resistant microorganisms—leading to difficulties in selecting the optimal antimicrobial treatment. Without prompt recognition, these infections severely hamper the patient’s quality of life and can develop into life-threatening complications. We report here the case of a 50-year-old woman with a history of recurring cholangitis with occasional systemic involvement leading to bloodstream infection, who ultimately received a diagnosis of CHF and was put on chronic suppressive antibiotic therapy while on the waiting list for a liver transplant. We also reviewed the literature collecting cases of recurrent infections occurring in patients with ductal plate malformation.

Abstract
Fibropolycystic liver disorders (FLD) arise from abnormal development of the ductal plate and are classified according to the size of the affected hepatobiliary duct. Congenital hepatic fibrosis (CHF) has small duct involvement characterized by a variable degree of periportal fibrosis and hyperplasia without affecting the liver’s architecture. Caroli’s disease (CD) is a rare autosomal recessive disorder with a prevalence of one case per 1,000,000 people and is characterized by cystic dilation of large intrahepatic ducts. When the disease presents with congenital hepatic fibrosis, it is referred to as Caroli’s syndrome (CS). Patients are usually diagnosed around the age of 20 with episodes of cholangitis, portal hypertension or hepatomegaly. We present the case of a two-year-old male with a previous history of autosomal recessive polycystic kidney disease (ARPKD) who presented to the emergency room with variceal bleeding secondary to portal hypertension. The physical examination showed an acutely ill-looking boy, with evident paleness and distended abdomen. Past medical history was negative for previous gastrointestinal bleeding or episodes of cholangitis. An upper gastrointestinal endoscopy was performed, showing esophageal varices secondary to portal hypertension. Imaging studies revealed hepatosplenomegaly, alterations in liver echogenicity, and dilated saccular bile ducts affecting both liver lobes without observing any apparent obstruction, highly suggestive of CD. A liver biopsy revealed nodular liver tissue with marked fibrosis between nodules, which confirmed the presence of CHF. Both kidneys were increased in size, hyperechoic and with loss of corticomedullary differentiation. FLD commonly present with coexisting hepatobiliary and renal alterations. Therefore, starting at the time of initial diagnosis, all patients with ARPKD should be evaluated to detect liver abnormalities due to the high association. Despite the rarity of CS, especially in early childhood, the association between ARPKD and FLD is well documented. So if this clinical presentation arises, CS should be suspected.

Abstract
Fibropolycystic diseases of the liver comprise a spectrum of disorders affecting bile ducts of various sizes and arise due to an underlying ductal plate malformation (DPM). We encountered a previously unreported variant of DPM, the hilar fibropolycystic disease which we diagnosed in the explant liver. A 2-year-old boy was referred for liver transplantation with a diagnosis of biliary atresia (BA) and failed Kasai portoenterostomy (KPE). He had cirrhosis with portal hypertension along with synthetic failure indicated by coagulopathy and hypoalbuminemia. The child underwent liver transplant successfully. The explant liver had fibropolycystic disease confined to the perihilar liver and hilum. No pathogenic mutation was detected by whole exome sequencing. Fibropolycystic liver disease may represent a peculiar anatomical variant, which can be diagnosed by careful pathological examination of the explant liver. The neonatal presentation of hilar fibropolycystic liver disease can be misdiagnosed as BA.

Abstract
Congenital hepatic fibrosis (CHF) often accompanies autosomal recessive polycystic kidney disease (ARPKD), which stems from a PKHD1 gene mutation. The aim of this study was to clarify the prognosis of children with CHF who received living donor liver transplantation (LDLT) from donors who might be heterozygous carriers of a hepatorenal fibrocystic disease. Fourteen children with CHF who underwent LDLT at our center were enrolled. Eight and two patients had ARPKD and nephronophthisis, respectively. Eight of the donors were the recipients' fathers, and six donors were their mothers. We examined the histological and radiological findings of the donor livers and complications in the recipients following the liver transplantation. Seven of the donor livers presented morphological abnormalities of the bile ducts. Abdominal computed tomography revealed liver cysts in eight donors. One recipient underwent re-LT for graft failure due to rejection. Three patients presented with rejection, and one presented with sepsis. The overall survival rate was 100% and the original graft survival rate was 93%. In conclusion, the prognosis of recipients who received a LDLT from their parents for CHF was excellent. However, the morphology of half the donor livers was abnormal. Careful follow-up is needed to ensure long-term graft survival.

Abstract
AIM To evaluate the novel platelet-derived growth factor receptor and vascular endothelial growth factor receptor dual kinase inhibitor ANG3070 in a polycystic kidney disease-congenital hepatic fibrosis model.
METHODS At 6 wk of age, PCK rats were randomized to vehicle or ANG3070 for 4 wk. At 10 wk, 24 h urine and left kidneys were collected and rats were continued on treatment for 4 wk. At 14 wk, 24 h urine was collected, rats were sacrificed, and liver and right kidneys were collected for histological evaluation. For Western blot studies, PCK rats were treated with vehicle or ANG3070 for 7 d and sacrificed approximately 30 min after the last treatments.
RESULTS Compared to the wild-type cohort, the PCK kidney (Vehicle cohort) exhibited a marked increase in kidney and liver mass, hepato-renal cystic volume, hepato-renal fibrosis and hepato-renal injury biomarkers. Intervention with ANG3070 in PCK rats decreased kidney weight, reduced renal cystic volume and reduced total kidney hydroxyproline, indicating significantly reduced rental interstitial fibrosis compared to the PCK-Vehicle cohort. ANG3070 treatment also mitigated several markers of kidney injury, including urinary neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, cystatin C and interleukin-18 levels. In addition, this treatment attenuated key indices of renal dysfunction, including proteinuria, albuminuria and serum blood urea nitrogen and creatinine, and significantly improved renal function compared to the PCK-Vehicle cohort. ANG3070 treatment also significantly decreased liver enlargement, hepatic lesions, and liver fibrosis, and mitigated liver dysfunction compared to the PCK-Vehicle cohort.
CONCLUSION These results suggest that ANG3070 has the potential to slow disease, and may serve as a bridge toward hepato-renal transplantation in patients with fibropolycystic disease.

Evidence for a "Pathogenic Triumvirate" in Congenital Hepatic Fibrosis in Autosomal Recessive Polycystic Kidney Disease. BIOMED RESEARCH INTERNATIONAL 2016; 2016:4918798.

Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is a severe monogenic disorder that occurs due to mutations in the PKHD1 gene. Congenital hepatic fibrosis (CHF) associated with ARPKD is characterized by the presence of hepatic cysts derived from dilated bile ducts and a robust, pericystic fibrosis. Cyst growth, due to cyst wall epithelial cell hyperproliferation and fluid secretion, is thought to be the driving force behind disease progression. Liver fibrosis is a wound healing response in which collagen accumulates in the liver due to an imbalance between extracellular matrix synthesis and degradation. Whereas both hyperproliferation and pericystic fibrosis are hallmarks of CHF/ARPKD, whether or not these two processes influence one another remains unclear. Additionally, recent studies demonstrate that inflammation is a common feature of CHF/ARPKD. Therefore, we propose a "pathogenic triumvirate" consisting of hyperproliferation of cyst wall growth, pericystic fibrosis, and inflammation which drives CHF/ARPKD progression. This review will summarize what is known regarding the mechanisms of cyst growth, fibrosis, and inflammation in CHF/ARPKD. Further, we will discuss the potential advantage of identifying a core pathogenic feature in CHF/ARPKD to aid in the development of novel therapeutic approaches. If a core pathogenic feature does not exist, then developing multimodality therapeutic approaches to target each member of the "pathogenic triumvirate" individually may be a better strategy to manage this debilitating disease.

Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is characterized by enlarged kidneys with dilated collecting ducts and congenital hepatic fibrosis. There is a variable rate of progression of kidney and liver disease. Portal hypertension and Caroli's disease occur from liver involvement that contributes to morbidity and mortality. Approximately 40 % of patients have a severe disease phenotype leading to rapid onset of end-stage kidney disease (ESKD) and signs of portal hypertension and the rest may have predominant involvement of either the kidney or liver. It is important for the physician to establish the extent of organ involvement before deciding on the ultimate plan of management, especially when transplantation is required. Isolated renal transplantation can be considered when liver involvement is minimal. If hepatobiliary disease is prominent, and kidney function is preserved, management options are based on individual characteristics. In the presence of significant liver disease and ESKD, consideration should be given to combined liver kidney transplantation, which can be beneficial in eliminating the consequences of both kidney and liver disease. However, this is a complex surgical procedure that needs to be performed at experienced transplant centers. Improvement in surgical techniques has considerably improved short-term graft survival with the added advantage of the liver offering immunologic protection to the kidney allograft.

Abstract
Genetic defects of cilia cause a wide range of diseases, collectively known as ciliopathies. Primary, or nonmotile, cilia function as sensory organelles involved in the regulation of cell growth, differentiation, and homeostasis. Cilia are present in nearly every cell in the body and mutations of genes encoding ciliary proteins affect multiple organs, including the kidneys, liver, pancreas, retina, central nervous system (CNS), and skeletal system. Genetic mutations causing ciliary dysfunction result in a large number of heterogeneous phenotypes that can manifest with a variety of overlapping abnormalities in multiple organ systems. Renal manifestations of ciliopathies are the most common abnormalities and include collecting duct dilatation and cyst formation in autosomal recessive polycystic kidney disease (ARPKD), cyst formation anywhere in the nephron in autosomal dominant polycystic kidney disease (ADPKD), and tubulointerstitial fibrosis in nephronophthisis, as well as in several CNS and skeletal malformation syndromes. Hepatic disease is another common manifestation of ciliopathies, ranging from duct dilatation and cyst formation in ARPKD and ADPKD to periportal fibrosis in ARPKD and several malformation syndromes. The unifying molecular pathogenesis of this emerging class of disorders explains the overlap of abnormalities in disparate organ systems and links diseases of widely varied clinical features. It is important for radiologists to be able to recognize the multisystem manifestations of these syndromes, as imaging plays an important role in diagnosis and follow-up of affected patients.

Abstract
Abnormalities in primary cilia lead to diseases called ciliopathies. Multiple organ involvement is the norm since primary cilia are present in most cells. When cholangiocyte cilia are abnormal, ductal plate malformation ensues leading to such conditions as congenital hepatic fibrosis, Caroli disease or syndrome, or other fibrocystic disease.

Abstract
BACKGROUND AND STUDY AIMS Fibropolycystic disease of liver and kidney (FPCDLK) is an uncommon group of conditions inherited in an autosomal fashion. The group encompasses autosomal dominant polycystic disease of the kidney (ADPDK), autosomal recessive polycystic disease of the kidney (ARPDK), congenital hepatic fibrosis (CHF) and Caroli's disease (CD). There are limited data of this disease in the world. We report our experience in the Royal Hospital (RH) in Oman and data regarding long-term follow-up. The aim of the study was to document the frequency of encounter, clinical presentation and outcome of FPCDLK in Division of Child Health in RH, Muscat. PATIENTS AND METHODS Charts of patients diagnosed with ARPDK, ADPDK, CHF and CD were reviewed from the period of 16 February 2006 till 31 December 2011. Parameters including anthropometry, liver function tests, renal function tests, presence of oesophageal varices, hypersplenism, renal or liver transplantation and performance of porto-systemic shunt surgeries were all investigated. RESULTS A total of 33 patients were identified, including 19 males and 14 females. The frequency of encounter of FPCDLK in RH was 1.5/1,000,000 population. The mean age of patients was 7.4years. The mean age at diagnosis was 27months. The mean duration of follow-up was 5.5years. A total of 31% of patients had an incidental finding of hepatomegaly, and 25% were detected by antenatal screening. Three children presented with renal failure, and 13 children in total had renal function abnormalities by the end of the study period. One child presented with haematemesis at the age of 1year. Two children underwent renal transplant and one child required splenectomy with a splenorenal shunt. A total of 54% had endoscopic variceal screen and two required banding on first endoscopy. The demise of one patient was observed during the study. CONCLUSION FPCDLK is uncommon in Oman but carries major mortality and morbidity for the patient and family. The gene is present in the Gulf countries. Management is mainly through portal hypertension and renal supportive care until definitive dual organ transplant. This disease needs to be further investigated in the Arab world.

Abstract
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.

Abstract
A 1-year-old girl had pancreaticobiliary maljunction, a choledochal cyst, and polycystic kidney. At the age of 4 years, she was treated by resection of the choledochal cyst and Roux-en-Y reconstruction because of the cyst's risk of cancer. She was diagnosed as having congenital hepatic fibrosis based on the histological findings. Postoperatively, she suffered recurrent fever of unknown origin, refractory to several antibiotics. At the age of 6 years, she underwent living donor liver transplantation from her father. Multi-drug-resistant Pseudomonas aeruginosa was cultured in the recipient's liver. After liver transplantation, she had no episodes of recurrent fever. Roux-en-Y reconstruction should be avoided for ductal plate malformations such as congenital hepatic fibrosis.
