Liver Transplantation in Primary Hyperoxaluria: A Single-Center 10-Year Experience. Pediatr Transplant 2025; 29:e70102. [PMID: 40394807 DOI: 10.1111/petr.70102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 01/22/2025] [Accepted: 05/06/2025] [Indexed: 05/22/2025]
Abstract
BACKGROUND Primary hyperoxalurias (PHs) are rare inborn errors of metabolism caused by a deficiency of hepatic enzymes, leading to excessive urinary oxalate excretion and the overproduction of oxalate, which accumulates in various organs. If left untreated, PHs can cause serious morbidity, end-stage kidney disease (ESKD), and mortality. Liver transplantation (LT) is a recognized treatment option for children with these diseases. This study aimed to analyze the outcome of PHs disease post-LT from a single center in Iran. METHODS This retrospective, single-center study was conducted at the Shiraz Transplant Center from 2012 to 2023, focusing on liver transplant recipients with PH. We evaluated long-term outcomes and post-transplantation results for both deceased donor liver transplantation (DDLT) and living donor liver transplantation (LDLT). Biochemical lab results (pre- and post-transplantation), perioperative data, surgical procedures, transplantation outcomes, and recipient and donor characteristics were reported. Kaplan-Meier survival analysis was used to assess graft and patient survival. RESULTS 33 recipients with LT (LDLT, n = 6; DDLT, n = 27) were included. The median age at the time of transplantation was 8 years (range: 3-18 years). Following liver transplantation, all of the patients had normalization of liver enzymes. Urine oxalate levels gradually decreased from 198 to 51 (< 45 mg/1.73 m2/day). Among the 33 patients, eight experienced episodes of acute rejection, and five developed chronic rejection. Eight patients underwent kidney transplantation before liver transplantation, while 21 patients initially received liver transplantation. 26 patients survived and remained in good health during a median follow-up period of 7 years (range: 1.5-11 years). For patients with PHs, the survival rates at 6 months, 1 year, 3 years, and 5 years were 100%, 97%, 94%, and 85%, respectively. The graft survival for patients was 100%, 100%, 97%, and 97% at 6 months, 1 year, 3 years, and 5 years, respectively. CONCLUSIONS PHs is a rare metabolic disorder, and LT significantly improves both survival and quality of life for affected patients. In our cohort, the majority of patients exhibited favorable long-term outcomes, along with a notable reduction in urine oxalate levels post-transplantation. However, challenges persist, including graft shortages and the risk of renal graft loss due to oxalosis, which continue to affect overall treatment outcomes. These findings highlight the importance of close monitoring and multidisciplinary care in managing PH patients' post-transplant.

Abstract
BACKGROUND Primary hyperoxaluria type 1 is responsible for pediatric kidney failure in 1 to 2% of cases. Novel therapies based on RNA interference are changing the natural history of the disease. However, for those who do progress to kidney failure, and for patients living in countries that cannot afford these expensive therapies, liver-kidney transplantation may remain the only efficient therapy. METHODS The aim of the study was to evaluate the outcome of patients with primary hyperoxaluria type 1 who received simultaneous or sequential liver-kidney transplantation. We retrospectively evaluated 10 patients, five of whom received a simultaneous transplantation, and five underwent sequential transplantation, with a median postponement of the kidney transplantation of 8 months (range 4-20). Among the patients, 5 were from medium-low income countries. RESULTS Median follow up was 3.2 years (range 1.6-11). Median estimated glomerular filtration rate at 6 and 12 months was 81.2 (range: 45.7-108.8) and 79.3 ml/min/1.73m2 (range 54.7-112.1) in patients who underwent simultaneous transplantation, and 45.7 (range 34.5-86.7) and 38.3 ml/min/1.73m2 (range 29.9-77.5) in those with sequential transplantation (p:NS). Biopsies performed at 6 and 12 months showed precipitation of calcium oxalate crystals in 7 patients, demonstrating the recurrence of deposition despite the delay between liver and kidney transplantation. No differences in kidney function or in post-transplant renal oxalate precipitation were observed between patients that underwent bilateral nephrectomy and those who did not. As of their most recent follow up, none of the patients has lost their kidney graft. CONCLUSIONS Our study shows that by adapting the transplant strategy to individual cases, patients with primary hyperoxaluria type 1 can be successfully treated.

Combined liver kidney transplantation for primary hyperoxaluria type 1: Will there still be a future? Current transplantation strategies and monocentric experience.

Abstract
Combined liver-kidney transplantation is a therapeutic option for children affected by type 1 primary hyperoxaluria. Persistently high plasma oxalate levels may lead to kidney graft failure. It is debated whether pre-emptive liver transplantation, followed by kidney transplantation, might be a better strategy to reduce kidney graft loss. Our experience of 6 pediatric combined liver-kidney transplants for primary hyperoxaluria type 1 in pediatric recipients was retrospectively analyzed. Plasma oxalate levels were monitored before and after transplantation. All the recipients were on hemodialysis at transplantation. Median [IQR] recipient's age at transplantation was 11 [1-14] years; in all cases, a compatible graft from a pediatric brain-dead donor aged 8 [2-16] years was used. In a median follow-up of 7 [2-19] years after combined liver-kidney transplantation, no child died and no liver graft failure was observed; three kidney grafts were lost, due to chronic rejection, primary non-function, and early renal oxalate accumulation. Liver and kidney graft survival remained stable at 1, 3, and 5 years, at 100% and 85%, respectively. Kidney graft loss was the major complication in our series. Risk is higher with very young, low-weight donors. The impact of treatment with glyoxalate pathway enzyme inhibitors treatment in children with advanced disease as well as of donor kidney preservation by ex vivo machine perfusion needs to be evaluated. At present, a case-by-case discussion is needed to establish an optimal treatment strategy.

Bilateral native nephrectomy to reduce oxalate stores in children at the time of combined liver-kidney transplantation for primary hyperoxaluria type 1. Pediatr Nephrol 2018; 33:881-887.

Abstract
OBJECTIVE Primary hyperoxaluria type-1 (PH-1) is a rare genetic disorder in which normal hepatic metabolism of glyoxylate is disrupted resulting in diffuse oxalate deposition and end-stage renal disease (ESRD). While most centers agree that combined liver-kidney transplant (CLKT) is the appropriate treatment for PH-1, perioperative strategies for minimizing recurrent oxalate-related injury to the transplanted kidney remain unclear. We present our management of children with PH-1 and ESRD on hemodialysis (HD) who underwent CLKT at our institution from 2005 to 2015. METHODS On chart review, three patients (2 girls, 1 boy) met study criteria. Two patients received deceased-donor split-liver grafts, while one patient received a whole liver graft. All patients underwent bilateral native nephrectomy at transplant to minimize the total body oxalate load. Median preoperative serum oxalate was 72 μmol/L (range 17.8-100). All patients received HD postoperatively until predialysis serum oxalate levels fell <20 μmol/L. All patients, at a median of 7.5 years of follow-up (range 6.5-8.9), demonstrated stable liver and kidney function. CONCLUSIONS While CLKT remains the definitive treatment for PH-1, bilateral native nephrectomy at the time of transplant reduces postoperative oxalate stores and may mitigate damage to the renal allograft.

Abstract
Primary hyperoxaluria type I (PH1), the most severe form of primary hyperoxalurias, is a liver disease of the metabolic defect in glyoxylate detoxification that can be corrected by liver transplantation. A 21-year-old man presented to our center after 4 months of regular hemodialysis for kidney failure caused by nephrolithiasis. A diagnosis of PH1 was confirmed by mutations of the AGXT gene. Left lateral sectionectomy of the native liver was performed; and auxiliary partial orthotopic liver transplantation (APOLT) and kidney transplantation were carried out synchronously using a living donor. After transplantation, the patient's plasma oxalate and creatinine levels substantially decreased and the patient recovered well with good dual grafts function. APOLT and kidney transplantation can compensate the liver deficient in liver enzyme production and aid the renal elimination of oxalate, thus serving as an effective treatment option for patients with PH1. In conclusion, left lateral sectionectomy of the native liver and combined living-related liver-kidney transplantation can be a surgical option for PH1.

Abstract
A five-yr-old boy developed chronic liver failure and ESKD because of CHF and juvenile NPHP. He underwent sequential liver and kidney transplantation with a compatible blood type from his father, at five yr, seven months and five yr, 11 months old, respectively. Because the patient was not in ESKD, we initially performed LDLT because of significant portal hypertension. Even after LDLT, his ascites was not ameliorated, and he needed continuous drainage of ascites and daily albumin and gamma globulin infusion. Thereafter, he progressed to ESKD and needed hemodialysis for one month before LDKT. CDC crossmatch for donor B cells in the warm test, FCXM for B cell IgG, and flow PRA for donor class II were positive before LDKT. After pretreatment of three courses of plasma exchange and intravenous gamma globulin, LDKT was performed. Two weeks after LDKT, AIHA concomitant with autoimmune thrombocytopenia, also called Evans syndrome, occurred because of passenger lymphocytes from the donor; however, the patient was successfully treated with intravenous methylprednisolone. Eighteen months have passed since LDKT, and liver and kidney function in both the recipient and donor are normal.

Abstract
Childhood urolithiasis is associated with considerable morbidity and recurrence. Many risk factors--including those metabolic, genetic, anatomic, dietary and environmental in nature--have been identified in children with urinary tract calculi. As pediatric urolithiasis with a metabolic etiology is the most common disease, evaluating the metabolic risk factors in patients is necessary to both effectively treat current stones and prevent recurrence. We discuss causative risk factors of pediatric urolithiasis, as well as the diagnostic and therapeutic approaches.

Abstract
PH1 is an inborn error of the metabolism in which a functional deficiency of the liver-specific peroxisomal enzyme, AGT, causes hyperoxaluria and hyperglycolic aciduria. Infantile PH1 is the most aggressive form of this disease, leading to early nephrocalcinosis, systemic oxalosis, and end-stage renal failure. Infantile PH1 is rapidly fatal in children unless timely liver-kidney transplantation is performed to correct both the hepatic enzyme defect and the renal end-organ damage. The surgical procedure can be further complicated in infants and young children, who are at higher risk for vascular anomalies, such as IVC thrombosis. Although recently a limited number of children with IVC thrombosis have underwent successful kidney transplantation, successful multi-organ transplantation in a child with complete IVC thrombosis is quite rare. We report here the interesting and technically difficult case of a three-yr-old girl with a complete thrombosis of the IVC, who was the recipient of combined split liver and kidney transplantation for infantile PH1. Although initial delayed renal graft function with mild-to-moderate acute rejection was observed, the patient rapidly regained renal function after steroid boluses, and was soon hemodialysis-independent, with good diuresis. Serum and plasma oxalate levels progressively decreased; although, to date they are still above normal. Hepatic and renal function indices were at, or approaching, normal values when the patient was discharged 15-wk post-transplant, and the patient continues to do well, with close and frequent follow-up. This is the first report of a successful double-organ transplant in a pediatric patient presenting with infantile PH1 complicated by complete IVC thrombosis.

Abstract
Primary hyperoxaluria type 1 (PH-1) is a rare autosomal recessive disease caused by the absence or deficiency of the liver-specific intermediary metabolic enzyme alanine glyoxylate aminotransferase. The prognosis of this metabolic disease is poor. Theoretically, the primary metabolic defect can be cured by liver transplantation. However, controversy exists around the age and stage of the disease that liver transplantation should be performed. We report on a patient who presented at the early age of 2 months with nephrocalcinosis. Isolated liver transplantation was performed at the age of 21 months. Eight years later, the estimated glomerular filtration rate was 85 ml/min/1.73 m(2), and imaging studies did not reveal nephrocalcinosis. This case report supports the strategy of early isolated liver transplantation in patients with PH-1.

Abstract
With advancements in the operative techniques, patient survival following liver transplantation (LTx) has increased substantially. This has led to the acceleration of pre-existing kidney disease because of immunosuppressive nephrotoxicity making additional kidney transplantation (KTx) inevitable. On the other hand, in a growing number of patients on the waiting list to receive liver, long waiting time has resulted in adverse effect of decompensated liver on the kidney function. During the last two decades, the transplant community has considered combined liver kidney transplantation (CLKTx) to overcome this problem. The aim of our study is to present an overview of our experience as well as a review of the literature in CLKTx and to discuss the controversy in this regard. All performed CLKTx (n = 22) at our institution as well as all available reported case series focusing on CLKTx are extracted. The references of the manuscripts were cross-checked to implement further articles into the review. The analyzed parameters include demographic data, indication for LTx and KTx, duration on the waiting list, Model for End-Stage Liver Disease (MELD) score, Child-Turcotte-Pugh (CTP) score, immunosuppressive regimen, post-transplant complications, graft and patient survival, and cause of death. From 1988 to 2009, a total of 22 CLKTx were performed at our institution. The median age of the patients at the time of CLKTx was 44.8 (range: 4.5-58.3 yr). The indications for LTx were liver cirrhosis, hyperoxaluria type 1, polycystic liver disease, primary or secondary sclerosing cholangitis, malignant hepatic epithelioid hemangioendothelioma, cystinosis, and congenital biliary fibrosis. The KTx indications were end-stage renal disease of various causes, hyperoxaluria type 1, polycystic kidney disease, and cystinosis. The mean follow-up duration for CLKTx patients were 4.6 +/- 3.5 yr (range: 0.5-12 yr). Overall, the most important encountered complications were sepsis (n = 8), liver failure leading to retransplantation (n = 4), liver rejection (n = 3), and kidney rejection (n = 1). The overall patient survival rate was 80%. Review of the literature showed that from 1984 to 2008, 3536 CLKTx cases were reported. The main indications for CLKTx were oxalosis of both organs, liver cirrhosis and chronic renal failure, polycystic liver and kidney disease, and liver cirrhosis along with hepatorenal syndrome (HRS). The most common encountered complications following CLKTx were infection, bleeding, biliary complications, retransplantation of the liver, acute hepatic artery thrombosis, and retransplantation of the kidney. From the available data regarding the need for post-operative dialysis (n = 673), a total of 175 recipients (26%) required hemodialysis. During the follow-up period, 154 episodes of liver rejection (4.3%) and 113 episodes of kidney rejection (3.2%) occurred. The cumulative 1, 2, 3, and 5 yr survival of both organs were 78.2%, 74.4%, 62.4%, and 60.9%, respectively. Additionally, the cumulative 1, 2, 3, and 5 yr patient survival were 84.9%, 52.8%, 45.4%, and 42.6%, respectively. The total number of reported deaths was 181 of 2808 cases (6.4%), from them the cause of death in 99 (55%) cases was sepsis. It can be concluded that there is still no definitive evidence of better graft and patient survival in CLKTx recipients when compared with LTx alone because of the complexity of the exact definition of irreversible kidney function in LTx candidates. Additionally, CLKTx is better to be performed earlier than isolated LTx and KTx leading to the avoidance of deterioration of clinical status, high rate of graft loss, and mortality. Shorter graft ischemia time and more effective immunosuppressive regimens can reduce the incidence of graft malfunctioning in CLKTx patients. Providing a model to reliably determine the need for CLKTx seems necessary. Such a model can be shaped based upon new and precise markers of renal function, and modification of MELD system.

Abstract
In PH, PLTX, although ideal in theory, is rarely achieved. Patients usually have reached end-stage kidney disease while requiring combined liver and kidney transplantation. In this combined procedure, the sudden high oxalates mobilization from blood and tissue stores jeopardizes the success of the kidney graft, with a high risk of post-transplant early kidney necrosis or chronic graft damage. Here, we report the case of a three-yr-old girl with PH and ESRF in whom we performed sequentially deceased donor liver transplantation followed four months later by living donor kidney transplant, after normalization of blood oxalate levels and improvement of urinary oxalate output. After this two-step transplantation, our patient showed normalization of renal function with good urinary output and maintained normal blood oxalate levels. This strategy seems to be a reasonable approach in order to avoid acute renal tubular injury because of oxalate excretion in these patients.

Abstract
BACKGROUND Cure of the metabolic defect in primary hyperoxaluria type 1 (PH1) is possible with liver transplantation (LTx). Preemptive LTx (PLTx) was promoted to prevent chronic kidney disease due to nephrocalcinosis and urolithiasis. However, timing of this procedure is difficult in view of the heterogeneity of PH1 and effective conservative treatment. Combined liver-kidney transplantation (LKTx) is able to cure metabolic defect and replace renal function at the same time and is effective and indicated for patients with or approaching end-stage renal disease (ESRD). Sometimes a sequential approach for LKTx (first liver, then kidney) has been recommended. METHODS We report on 13 patients with PH1 since 1995 who underwent transplantation procedures in our center for PH1 at a median age of 4.7 (range 1.4-8.9) years. RESULTS The first two patients, planned for a sequential strategy, died early after LTx because of infectious complications. Four patients underwent PLTx at a median glomerular filtration rate of 65 (range 27-98) mL/min/1.73 m/day (Hoppe et al., Pediatr Nephrol 1996; 10: 488), and three patients still have sufficient residual renal function after a follow-up of median 11.6 years. Seven patients with ESRD received a combined LKTx, including four with infantile oxalosis, and three weighing less than 10 kg. There was no mortality and catch-up growth was observed in most patients. CONCLUSION In summary and conclusion, transplantation procedures are challenging in PH1, but our results including growth data are encouraging. PLTx remains an option despite the difficulties in timing the procedure. LKTx is indicated for patients with ESRD and is possible even in patients with infantile oxalosis and may improve longitudinal growth.
