Abstract
BACKGROUND Erythropoietic protoporphyria is a rare disease of heme biosynthesis resulting in excessive accumulation of protoporphyrin in various organs. The most typical symptom is photosensitivity caused by activated protoporphyrins (wavelength ~400 nm). Accumulated protoporphyrin in the liver also causes liver failure, and liver transplantation is the only life-saving treatment. Phototoxic injury to abdominal organs has been reported during liver transplantation. Thus, to avoid phototoxic injury during liver transplantation, it has previously been conducted with only shadowless lights and ceiling lights off in the operating theater. Here, we report a case of a safe and successful liver transplantation in a patient with erythropoietic protoporphyria where the operating theater lights were covered with polyimide film. CASE PRESENTATION A 50-year-old man presented with hepatic failure owing to erythropoietic protoporphyria. Before liver transplantation, the shadowless lights and ceiling lights in the operating theater were covered entirely with polyimide film. This filter completely blocked the harmful wavelength of light (400-470 nm). Orthotopic liver transplantation was safely and successfully performed with adequate illumination and patient monitoring. The patient followed a normal postoperative course without phototoxic injuries or protoporphyrin re-accumulation. CONCLUSION Covering not only shadowless lights but also all ceiling lights in the operating theater with the polyimide film allowed safe surgery, safe anesthesia, and safe monitoring of the patient who underwent liver transplantation for severe liver failure owing to erythropoietic protoporphyria.

Abstract
The porphyries are a group of metabolic disorders characterized by deficiencies in the activity of enzymes involved in the biosynthesis of heme. In erythropoietic protoporphyria (EPP), in the majority of cases an autosomal dominant disease, there is a mutation of the gene that encodes ferrochelatase (FECH). FECH deficiency is associated with increased concentrations of protoporphyrin in erythrocytes, plasma, skin and liver. The prevalence of this inherited disorder oscillates between 1:75 000 and 1:200 000. Clinical manifestations of EPP appear in early infancy upon first exposure to the sun. Nevertheless, approximately 5%-20% of patients with EPP develop liver manifestations. Retention of protoporphyrin in the liver is associated with cholestatic phenomena and oxidative stress that predisposes to hepatobiliary disease of varying degrees of severity, such as cholelithiasis, mild parenchymal liver disease, progressive hepatocellular disease with end-stage liver disease and acute liver failure. Liver damage is the major risk in EPP patients, so surveillance and frequent clinical and biochemical liver follow-up is mandatory. The diagnostic approach consists in detecting increased levels of protoporphyrin, decreased activity of FECH and genetic analysis of the FECH gene. A variety of non-surgical therapeutic approaches have been adopted for the management of EPP associated with liver disease, but none of these has been shown to be unequivocally efficacious. Nevertheless, some may have a place in preparing patients for liver transplantation. Liver transplantation does not correct the constitutional deficiency of FECH. Consequently, there is a risk of recurrence of liver disease after liver transplantation as a result of continuing overproduction of protoporphyrin. Some authors recommend that bone marrow transplantation should be considered in liver allograft recipients to prevent recurrence of hepatic disease.

Abstract
Porphyrias are a heterogenous group of diseases that may result in disabling or life threatening neurovisceral symptoms and/or cutaneous photosensitivity. In acute intermittent porphyria, the clinical features, particularly neurological symptoms, may be life-threatening and disabling. Conventional treatment with human hemin, though effective in reducing symptoms, does not reverse neuropathy when structural nerve damage has occurred and may cause intense phlebitis. Liver transplantation (LT) may be considered as treatment for those with repeated life-threatening acute attacks resulting in poor quality of life, requirement of ventilatory support, and progressive loss of venous access due to hemin infusion. Patients with variegate porphyria (VP) present after puberty with neurovisceral symptoms and skin manifestations. LT resolved VP in the 1 patient reported in the literature. Aminolaevulinic acid dehydratase deficient porphyria is a rare autosomal recessive disorder and a child who presented with failure to thrive and required transfusions and parenteral nutrition did not improve with LT. In erythropoietic protoporphyria (EPP), there is excessive production of protoporphyrin in the bone marrow. Protoporphyrin is hepatotoxic and pigment loading of hepatocytes and bile canalicular sludging may result in progressive cholestasis and cirrhosis. LT is beneficial for such patients with end-stage liver disease. Perioperative management includes use of filters on operative lights to prevent skin burns and intestinal perforation. Other concerns include development of neuropathy, biliary complications, and recurrent liver disease. This review addresses the rationale, patient selection, evaluation, management issues, and technique of performing LT in various types of porphyria.

Abstract
Erythropoietic protoporphyria (EPP) is characterized by toxic accumulation of the hydrophobic compound protoporphyrin (PP). Ferrochelatase-deficient (fch/fch) mice are an animal model for human EPP. Recently, we have demonstrated that the accumulation of another hydrophobic compound, unconjugated bilirubin, could effectively be treated by stimulation of fecal fat excretion. We investigated whether stimulation of fecal fat excretion enhanced the disposal of PP in fch/fch mice. Fch/fch mice were fed for 8 wk with a high-fat diet (16 wt% fat; control) or with the high-fat diet mixed with either a nonabsorbable fat (sucrose polyester) or the intestinal lipase inhibitor orlistat. The effects of the treatments on fecal excretion of fat and PP and on hepatic PP concentrations were compared with control diets. Fecal fat excretion in fch/fch mice on a high-fat diet was higher than in mice on a low-fat diet (+149%, P < 0.05). Sucrose polyesters and orlistat increased fecal fat excretion even more, up to sixfold of control values. However, none of the different treatments affected fecal PP excretion or hepatic PP concentration. Treatment of fch/fch mice with a high-fat diet, a nonabsorbable fat diet, or with orlistat increased the fecal excretion of fat but did not increase fecal PP excretion or decrease hepatic PP concentration. The present data indicate that accumulation of PP is not amenable to stimulation of fecal fat excretion.

Abstract
In erythropoietic protoporphyria (EPP), there is excessive production of protoporphyrin, primarily in the bone marrow, resulting in increased biliary excretion of this heme precursor. Some patients will develop progressive liver disease that may ultimately require liver transplantation. However, excessive production of protoporphyrin by the bone marrow continues after transplantation, which may cause recurrent disease in the allograft. This study was performed to define post-transplant survival, the risk of recurrent disease, and specific management issues in patients transplanted for EPP liver disease. The patients studied consisted of twelve males and eight females, with an average age of 31 (range, 13-56) years at the time of transplantation. The estimated maximum MELD score prior to transplant was 21 (range, 15-29). Unique complications in the perioperative period were light induced tissue damage in four patients and neuropathy in six, requiring prolonged mechanical ventilation in four. Patient and graft survival rates were 85% at 1 year, 69% at 5 years, and 47% at 10 years. Recurrent EPP liver disease occurred in 11 of 17 patients (65%) who survived more than 2 months. Three patients were retransplanted at 1.8, 12.6, and 14.5 years after the initial transplant for recurrent EPP liver disease. In conclusion, the 5-year patient survival rate in patients transplanted for EPP liver disease is good, but the recurrence of EPP liver disease appears to diminish long term graft and patient survival.

Abstract
The skin, easily accessible for medical examination, is affected in many ways by liver transplantation. Mucocutaneous manifestations of advanced liver disease and dermatologic conditions associated with specific hepatic diagnoses generally improve after liver transplantation. Vasculitic lesions due to cryoglobulinemia associated with hepatitis C, and photosensitivity due to porphyria are occasional exceptions. Dermatologic diseases complicating the posttransplantation course can be challenging. Their presentation is sometimes unusual and their course severe. Infections with rare organisms alone or in combination may occur. Our intent is to provide an overview of the current knowledge regarding nontumoral dermatologic problems associated with liver transplantation by summarizing the available information from all documented case reports.

Abstract
The erythropoietic porphyrias are erythropoietic protoporphyria, and congenital erythropietic porphyria. Diagnosis is made based on clinical manifestations, and their characteristic porphyrin profiles. There are multiple treatment options for these two porphyrias, however, aside from bone marrow transplant for CEP, none is curative.

Abstract
A case of liver transplantation is described in a 35-year-old male with hepatic failure due to erythropoietic protoporphyria. Data regarding protoporphyrin levels in erythrocytes and faeces, before and after transplantation, seem to indicate that, in this case, protoporphyrin overproduction was, in part, due to liver synthesis. Four years after surgery, the patient is completely free of skin photosensitivity. Liver function tests are normal and there are no significant protoporphyrin deposits in the new liver. However, recurrence of the disease in the long-term cannot be excluded, since erythrocyte protoporphyrin levels have remained elevated after liver transplantation.

Abstract
Erythropoietic protoporphyria (EPP) is characterized clinically by cutaneous photosensitivity and biochemically by the accumulation of excessive amounts of protoporphyrin in erythrocytes, plasma, feces, and other tissues, such as the liver. The condition is inherited as an autosomal dominant or recessive trait, with a deficiency of ferrochelatase activity. A major concern in EPP patients is the development of cholestasis with accumulation of protoporphyrin in hepatobiliary structures and progressive cellular damage, which can rapidly lead to fatal hepatic failure. The availability of a mouse model for the disease, the Fech(m1Pas)/Fech(m1Pas) mutant mouse, allowed us to test a cellular therapy protocol to correct the porphyric phenotype. When Fech/Fech mice received bone marrow cells from normal animals, the accumulation of protoporphyrin in red blood cells and plasma was reduced 10-fold but still remained 2.5 times above normal levels. Interestingly, in very young animals, bone marrow transplantation can prevent hepatobiliary complications as well as hepatocyte alterations and partially reverse protoporphyrin accumulation in the liver. Bone marrow transplantation may be an option for EPP patients who are at risk of developing hepatic complications.

Abstract
Erythropoietic protoporphyria (EPP) is marked by a deficiency of ferrochelatase, which occurs in all cells and tissues, preventing effective conversion of proto porphyrin IX to heme and thereby blocking effective feedback inhibition of heme synthesis. The major source of the excess protoporphyrin is the bone marrow. Protoporphyrin IX may accumulate, with resultant toxicity chiefly of the marrow, skin, nervous system, and liver. Orthotopic liver transplantation (OLT) is, at present, the only adequate intervention for severe liver compromise secondary to protoporphyrin deposition, but it has been complicated by severe photosensitivity and polyneuropathy. Intravenous heme and plasmapheresis have been proposed but not previously reported as means to reduce the protoporphyrin burden before liver transplantation. We report a man with EPP who underwent preoperative heme-albumin administration and plasmaphereses that led to marked reductions in plasma and erythrocyte protoporphyrin levels. His OLT was uneventful, and he developed neither polyneuropathy nor exacerbation of photosensitivity.

Abstract
Liver transplantation provides an effective means for replacing a failing liver, in addition to correcting the underlying abnormality in many metabolic disorders. Results of liver transplantation for metabolic diseases have been generally encouraging, with the exception of hereditary hemochromatosis, in which infectious and cardiac complications appear to increase post-transplant mortality. Better pretransplant diagnosis of hemochromatosis, utilizing the recently identified putative gene, may help reduce post-transplant complications. In metabolic diseases, improved understanding of the underlying genetic and molecular defects will lead to advances in medical therapy and perhaps a decreased need for liver transplantation. NTBC therapy for hereditary tyrosinemia and purified glucocerebroside therapy for Gaucher disease are two such examples. The prospects of gene therapy are being actively pursued for many metabolic diseases, such as CF, hemophilia, and familial hypercholesterolemia. Until such investigation leads directly to clinical practice, however, liver transplantation remains an effective option for therapy for a wide range of metabolic diseases.

Abstract
The tremendous success of OLT as a highly effective treatment for patients with end-stage liver disease has resulted in a rapid increase in the number of candidates for the procedure. Refinements in organ preservation, improvements in surgical technique and immunosuppression, and better postoperative management have contributed to improved survival rates. The discrepancy between the paucity of organs and the increasing numbers of potential recipients will continue to worsen until there are extraordinary breakthroughs in providing alternatives to human whole-organ livers, such as xenografts or cultured hepatocyte infusions. For now, the vast majority of patients with life-threatening liver disease are not likely to receive a liver graft. Thus, the issues of patient selection and timing of OLT have become even more relevant. Prompt referral to a transplant center is not only in the patient's best interest, but also it has been shown to be cost-effective. Over the last 30 years, it has become clear that hepatic malignancy, initially a common reason for OLT, should be an indication for transplantation only in highly selected individuals. The role of adjuvant chemotherapy needs to be defined, and proven treatment alternatives need to be developed. New antiviral agents may enable a large group of patients with chronic hepatitis B to be successfully transplanted, placing even greater demands on the already limited supply of donor livers. Hepatitis B appears to be species specific, and it is conceivable that xenotransplantation from a nonsusceptible donor species may confer protection to HBV reinfection, eliminating the problems of an inadequate donor supply. Until novel approaches, including xenotransplantation, gene therapy, or replacement of hepatic function by cultured hepatocyte infusions, become a widespread reality, future allocation policies may highlight outcome as well as urgency as a fundamental variable to determine if transplantation is reasonable. Survival rates have been shown to fall with advancing levels of urgency, resulting in a conflict between equity and efficacy in organ allocation. As waiting lists for liver transplantation continue to grow, it is becoming increasingly apparent that patients must be referred to a transplant center earlier in the course of liver disease.

Abstract
Protoporphyria is a genetic disorder in which patients may develop severe protoporphyrin-induced liver damage and require transplantation. Because unique problems occur in the perioperative period and because excess production of protoporphyrin by the bone marrow continues after liver transplantation, the efficacy of this procedure for protoporphyric liver disease is uncertain. We present follow-up of nine patients who underwent liver transplantation. Two patients died within 2 months of transplantation, one from complications of abdominal bleeding and the other from sepsis after bowel perforations. The remaining seven patients had follow-up at 14 months to 8 years after transplantation (mean, 3.8 years). Two of the seven had suffered skin burns from exposure to operating room lights, which healed without scarring. Three had axonal neuropathies in the postoperative period requiring prolonged mechanical ventilation, and motor defects persisted in two. Five patients had normal liver chemistries at follow-up (mean, 3.5 years), with liver biopsy results normal or showing mild portal triad abnormalities, but erythrocyte protoporphyrin levels remained significantly elevated (1,765 +/- 365 mcg/dL; normal, < 65). The other two patients, both of whom had rejection, cytomegalovirus infection, and biliary tract obstruction requiring endoscopic therapy, had a recurrence of protoporphyric liver disease as indicated by liver biopsy features. One died 5 years after transplantation from complications of the liver disease. The other was stable 3.3 years after transplantation and was being monitored for possible retransplantation. Thus, liver transplantation can be performed successfully in patients with protoporphyric liver disease, with intermediate survival rates comparable to the general transplant population. However, disease may recur in the graft, particularly if there are complications that cause cholestasis.

Abstract
In a 58-year-old woman with erythropoietic protoporphyria, asymptomatic liver involvement had been diagnosed 12 years earlier. For more than 20 years the patient had been known to have symptomatic gallstones. A mild polyneuropathy of the lower limbs had been diagnosed several years ago. In December 1992, she presented with colicky upper abdominal pain, dyspepsia and mild jaundice. Diagnosis of beginning cholestasis in erythrohepatic protoporphyria and coincidental choledocholithiasis was made. A causal relation between choledocholithiasis and deterioration of liver function was assumed. Endoscopic extraction of the bile duct stones, however, could not prevent the development of terminal hepatic failure. Biochemically, an excessive protoporphyrinemia and coproporphyrinuria were found. Five weeks after presentation, the patient underwent orthotopic liver transplantation. Immediately after the operation she developed a severe axonal neuropathy with cranial nerve involvement. One year after transplantation, her general condition has markedly improved, but there is still a disabling polyneuropathy. Recently, there were single reports on patients with very similar neurological symptoms following liver transplantation in erythropoietic protoporphyria. This case supports the assumption of a distinct protoporphyrin-induced neural damage in severe hepatic failure.

Abstract
BACKGROUND/AIMS Erythropoietic protoporphyria, caused by ferrochelatase deficiency, leads to protoporphyrin accumulation in the liver. Therapeutic attempts to increase the secretion of this hydrophobic organic anion into bile are hampered by a lack of understanding of the secretory mechanism(s) involved. We have investigated biliary secretion of protoporphyrin in rats and mice, primarily targeted on the role of biliary lipids in this process. METHODS Gel permeation chromatography was applied to investigate the association of porphyrins with lipid fractions in bile. Secretion of endogenous porphyrins was studied in (GY mutant) rats and mdr2 P-glycoprotein deficient mice, under conditions of widely varying biliary lipid secretion rates. RESULTS Gel permeation chromatography revealed that, in native human and rat bile, protoporphyrin associated with cholesterol/phospholipid vesicles upon elution with bile salt-free buffer. In contrast, the more hydrophilic coproporphyrin isomers I and III were found only in bile salt/organic anion hybrid particles and smaller aggregates. Interruption of the enterohepatic circulation in normal Wistar rat resulted in parallel decrease of endogenous protoporphyrin-, lipid-, and bile salt secretion, but did not alter the secretion of coproporphyrin I and III. Uncoupling of lipid- from bile salt secretion by sulfated taurolithocholate resulted in impaired secretion into bile of protoporphyrin only. Conversely, secretion of coproporphyrin I and III, but not that of protoporphyrin, was impaired in mutant Groningen Yellow rats with defective ATP-dependent hepatobiliary organic anion transport. In mice homozygous for a disruption of the mdr2 P-glycoprotein gene, resulting in complete absence of phospholipids in bile and strongly reduced cholesterol output, secretion of protoporphyrin was reduced by 90%, whereas that of coproporphyrin I and III was affected to a much lesser extent. CONCLUSIONS Our data demonstrate a close association between protoporphyrin and lipid secretion into bile, indicating that these processes are, at least functioning coupled. This finding implicates a role of mdr2 P-glycoprotein activity in hepatobiliary removal of the hydrophobic organic anion protoporphyrin. Hence, it may be speculated that protoporphyrin secretion can be influenced by drugs, diet or other means that affect biliary lipid secretion.

Abstract
The rapid progress in the development of molecular technology has resulted in the identification of most of the genes of the heme biosynthesis pathway. Important problems in the pathogenesis and treatment of porphyrias now seem likely to be solved by the possibility of creating animal models and by the transfer of normal genes or cDNAs to target cells. Animal models of porphyrias naturally occur for erythropoietic protoporphyria and congenital erythropoietic porphyria, and different murine models have been or are being created for erythropoietic and hepatic porphyrias. The PBGD knock-out mouse will be useful for the understanding of nervous system dysfunction in acute porphyrias. Murine models of erythropoietic porphyrias are being used for bone-marrow transplantation experiments to study the features of erythropoietic and hepatic abnormalities. Gene transfer experiments have been started in vitro to look at the feasibility of somatic gene therapy in erythropoietic porphyrias. In particular, we have documented sufficient gene transfer rate and metabolic correction in different CEP disease cells to indicate that this porphyria is a good candidate for treatment by gene therapy in hematopoietic stem cells. With the rapid advancement of methods that may allow more precise and/or efficient gene targeting, gene therapy will become a new therapeutic option for porphyrias.

Abstract
Erythropoietic protoporphyria (EPP) is an inherited inborn error of porphyrin metabolism caused by decreased activity of the enzyme ferrochelatase, the terminal enzyme of the haem biosynthetic pathway, which catalyses the insertion of iron into protoporphyrin to form haem. EPP is characterized clinically by photosensitivity to visible light commencing in childhood, and biochemically by elevated red cell protoporphyrin levels. Although the majority of papers and reviews have classified EPP as an autosomal dominant disorder, the inheritance has now been shown to be more complex, and both autosomal dominant and recessive patterns of inheritance have been demonstrated using ferrochelatase activity. Further molecular studies should clarify the exact mode of inheritance. It seems likely that in the majority of families a defective allele from the apparently normal parent will be required for disease expression, but another possibility is autosomal dominant inheritance with low clinical penetrance. Exposure to bright sunlight, for as little as a few minutes in the worst affected patients, causes burning pain in exposed skin, which may be so severe and persistent that it prevents sleep for several nights. Patients usually attempt to relieve the pain by cold water or cold compresses. Apart from sun avoidance, the mainstay of prophylactic treatment has been beta-carotene. Although the published evidence for the effectiveness of beta-carotene is impressive, no controlled trials using adequate doses have been performed to unequivocally confirm its usefulness. The most serious complication of EPP is acute hepatic failure, which is due to accumulation of protoporphyrin in the liver. If jaundice develops, a rapidly fatal outcome often follows, unless liver transplantation is undertaken. Regular monitoring of liver function and red cell porphyrin levels is advisable, but this does not always identify patients before serious liver damage has occurred. Even when patients are identified at an early stage in the development of liver disease the therapeutic options available to prevent further damage are limited, and have not been fully evaluated. The gene for ferrochelatase has been cloned, sequenced and mapped to the long arm of chromosome 18. As mutations continue to be identified, phenotype/genotype correlations should become apparent, and it may eventually be possible to identify those patients at risk of developing hepatic failure. In addition, as the basic enzymatic defect in EPP is at the level of the bone marrow stem cells, which are the target cells of choice in the development of retroviral-mediated gene transfer, definitive treatment of EPP by gene therapy is a distinct hope for the future.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A simple and fast HPLC method for the determination of porphyrins in bile without extraction is described. Porphyrins were determined in bile from control subjects and from patients after orthotopic liver transplantation, including three patients with erythropoietic protoporphyria. It was found that: 1) coproporphyrin I is the predominant porphyrin in bile of controls, accompanied by some coproporphyrin III and protoporphyrin, whereas protoporphyrin mostly but not always is the predominant porphyrin in the bile of erythropoietic protoporphyria patients. In two of the three erythropoietic protoporphyria patients, the bile contained a hundred times more protoporphyrin than that of non-porphyric orthotopic liver transplantation patients. The third erythropoietic protoporphyria patient remained cholestatic and was unable to excrete sufficient amounts of protoporphyrin. 2) All investigated bile samples contained no secondary porphyrins derived from protoporphyrin, i.e. no deutero-, pempto-, or mesoporphyrin. Even when extracts of bile and serum were concentrated fifty to a hundred times, no traces of deutero-, pempto- and mesoporphyrin were detected. This complete absence of secondary porphyrins suggests that an enterohepatic circulation of dicarboxylic porphyrins from the distal gastrointestinal tract does not exist. 3) The HPLC chromatograms contain peaks from unknown compounds. No correlation between porphyrins and these compounds was found. Porphyrin profiles were followed in the bile of some orthotopic liver transplantation patients. Three episodes are recognizable. During the first three days after orthotopic liver transplantation there is a very high coproporphyrin excretion. There is then a lag of one to three weeks, in which no or very low porphyrin concentrations are detectable, followed by the restoration of normal biliary porphyrin patterns.
