Nonsyndromic paucity of intrahepatic bile ducts in infancy and idiopathic ductopenia in adulthood: the same syndrome?

Eleven patients with chronic intrahepatic cholestasis in whom a liver biopsy specimen showed unexplained bile duct paucity were investigated. Cholestasis developed during the neonatal period in three, at infancy (before 14 yr) in four and after 14 yr in the remaining four patients. In all patients other conditions characterized by chronic cholestasis associated with ductopenia such as primary biliary cirrhosis, primary sclerosing cholangitis, drug-induced liver disease, sarcoidosis or graft-vs.-host disease were excluded. Cardiovascular abnormalities in the three patients who had neonatal cholestasis permitted diagnosis of Alagille's syndrome. Clinical, biochemical and histological features were similar in the remaining eight patients, independent of the age at which the disease appeared. Idiopathic adulthood ductopenia may be a late-onset form of the nonsyndromic paucity of interlobular bile ducts seen in children, or it may be due to a still-unidentified cause that strikes later in life.     

Idiopathic adulthood ductopenia: case report and review of the literature

The clinical and pathological findings of idiopathic ductopenia were studied in a 30-year-old woman who initially manifested jaundice and pruritus. Serum biochemical tests of liver function indicated severe and progressive cholestasis. Viral hepatitis markers and circulating autoantibodies were absent. The patient had a normal cholangiogram and lacked evidence of inflammatory bowel disease. Histological examination of a liver specimen showed severe cholestasis and absence of interlobular bile ducts. Severe jaundice and intractable pruritus developed in the patient and served as the indications for liver transplantation 4 months after initial examination. Transplantation resulted in prompt and complete resolution of the jaundice and pruritus. Two types of idiopathic adulthood ductopenia associated with different prognoses are recognized. Patients with type 1 idiopathic adulthood ductopenia are asymptomatic or manifest symptoms of cholestatic liver disease. They tend to have less destruction of the intrahepatic bile ducts on liver biopsy specimens. Their clinical course ranges from spontaneous improvement to progression to biliary cirrhosis. In contrast, patients with type 2 idiopathic adulthood ductopenia generally manifest initial symptoms of decompensated biliary cirrhosis, have extensive destruction of the intrahepatic bile ducts on liver biopsy, and frequently require orthotopic liver transplantation.     

Prolonged cholestasis and ductopenia following gold salt therapy

Abstract: Hepatotoxicity, predominantly cholestatic, is a rare adverse effect of gold salt therapy, which usually completely resolves within a few months. We report the case of a female patient treated for rheumatoid arthritis, who had gold salt overdose, and in whom acute cholestatic hepatitis occurred three weeks after beginning of therapy. Evolution of gold concentration was followed in plasma and urine, as well as in cutaneous and liver dry tissue. Liver biopsy showed marked inflammatory changes of interlobular bile ducts that evolved towards ductopenia, which was responsible for prolonged cholestasis still present 15 months later. In addition, sialadenitis with sicca syndrome was noted six months after onset of the disease. The mechanism of hepatotoxicity was probably immunoallergic since liver lesions were associated with hypersensitivity syndrome including dermatitis and blood and tissue eosinophilia. This is the first report of gold salt hepatotoxicity with histological demonstration of cholangitis followed by ductopenia.     

Vanishing bile duct syndrome in a patient with advanced AIDS

A 39-year-old HIV-infected woman developed signs and symptoms of obstructive jaundice and cholestasis. Serological tests were positive for cytomegalovirus (CMV) infection. There was no evidence of AIDS cholangiopathy in ultrasonography or magnetic resonance cholangiopancreatography (MRCP). A liver biopsy revealed marked ductopenia and the patient was diagnosed with vanishing bile duct syndrome, thought to be secondary to CMV infection as a result of profound immunosuppression. To the best of our knowledge, this is the first reported case of vanishing bile duct syndrome diagnosed in a patient with HIV/AIDS.     

Vanishing Bile Duct Syndrome in a Hodgkin's Lymphoma Patient with Fatal Outcome Despite Lymphoma Remission

Vanishing bile duct syndrome (VBDS) is a condition resulting from severe bile duct injury, progressive destruction, and disappearance of intrahepatic bile ducts (ductopenia) leading to cholestasis, biliary cirrhosis, and liver failure. VBDS can be associated with a variety of disorders, including Hodgkin''s lymphoma (HL). We describe a 33-year-old male patient who presented with lymphadenopathy and jaundice, and was diagnosed to have HL. Serum bilirubin worsened progressively despite chemotherapy, with a cholestatic pattern of liver enzymes. Diagnosis of VBDS was established on liver biopsy. Although remission from HL was achieved, the patient died of liver failure. Presence of jaundice in HL patients should raise the possibility of VBDS. This report discusses the difficulties of delivering chemotherapy in patients with liver dysfunction. HL-associated VBDS carries a high mortality but lymphoma remission can be achieved in some patients. Therefore, liver transplantation should be considered early in these patients.     

Familial idiopathic adulthood ductopenia: a report of five cases in three generations

BACKGROUND/AIMS: Idiopathic adulthood ductopenia is a cholestatic liver disease of unknown etiology. Although most cases are sporadic, familial cases do occur. METHODS: We describe a series of adult-onset bile duct depletion involving five members of an extended family spanning three generations. The proband, a 49-year-old man, presented in 1989 with asymptomatic elevation of liver enzyme tests. Investigations for chronic liver disease, including endoscopic retrograde cholangiopancreatography, were negative. Findings on liver biopsy progressed from normal in 1989 to striking loss of interlobular bile ducts in 1992. Ursodeoxycholic acid has resulted in improvement of liver enzyme tests. The proband's brother required a liver transplant at age 35 for cryptogenic cirrhosis. The proband's sister, age 42, has had intermittent jaundice and elevation of liver enzyme tests since 1971. Her liver biopsy findings progressed from normal in 1975, to striking bile duct damage by 1997. The proband's 21-year-old son has elevated liver enzyme tests and a liver biopsy consistent with idiopathic adulthood ductopenia. The proband's father had a liver biopsy at age 70 for investigation of a liver mass. It revealed extensive fibrosis and striking bile duct destruction. RESULTS/CONCLUSIONS: This is the largest series of familial idiopathic adulthood ductopenia reported, and the first with multiple generations described. Genetics appears to play a role in some cases of adulthood ductopenia. Ursodeoxycholic acid may be beneficial in the treatment of this condition.     

Vanishing bile duct syndrome related to DILI and Hodgkin lymphoma overlap: A rare and severe case

Vanishing bile duct syndrome is a rare acquired condition, characterized by progressive loss of intrahepatic bile ducts leading to ductopenia and cholestasis. It can be associated with infections, ischemia, drug adverse reactions, neoplasms, autoimmune disease, and allograft rejection. Prognosis is variable and depends on the etiology of bile duct injury. We report the case of a 25-year-old female with cholestatic hepatitis and concomitant intakes of hepatotoxic substances, such as garcinia, field horsetail, and ketoprofen. On suspicion of a drug-induced liver injury, the drugs were promptly withdrawn and ursodeoxycholic acid was started with initial clinical and laboratory improvement, and the patient was discharged from the hospital. One month later, she had a new increase in bilirubin levels and canalicular enzymes, requiring a liver biopsy that showed significant loss of intrahepatic bile ducts, which was compatible with vanishing bile duct syndrome. This was confirmed by using cytokeratin 19 on immunohistochemistry. There was subsequent lymph node enlargement in several chains, and relevant weight loss. Histological analysis of a cervical lymph node revealed nodular sclerosis-subtype classic Hodgkin lymphoma. In this setting, vanishing bile duct syndrome was related to Hodgkin lymphoma and a drug-induced liver injury overlap, leading to progressive cholestasis with a worse prognosis. The patient's response to chemotherapy was poor, requiring biological therapy with brentuximab vedotin. It is crucial for physicians to create a broad differential diagnosis in suspected vanishing bile duct syndrome patients, especially to rule out malignancies.     

Benign recurrent intrahepatic cholestasis: late initial diagnosis in adulthood

Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal recessive or sporadic disorder, characterized by recurrent episodes of intense pruritus and jaundice that resolve spontaneously without leaving considerable liver damage. The attacks can start at any age, but the first attack is usually seen before the second decade of life. We report the case of a young adult male patient with BRIC who presented with recurrent cholestatic jaundice and pruritus with negative work up for all possible etiologies and a liver biopsy consistent with intrahepatic cholestasis. He improved on treatment with rifampicin and has not suffered another attack on follow up. Although in adulthood, BRIC diagnosis should be kept in mind in patients with recurrent cholestatic attacks with symptom free intervals after main bile duct obstruction and other congenital or acquired causes of intrahepatic cholestasis excluded.     

Hodgkin's disease presenting as cholestatic hepatitis with prominent ductal injury

In advanced stages of Hodgkin's disease, liver involvement is common. However, Hodgkin's disease mimicking cholestatic hepatitis at presentation is rare. We describe a patient with Hodgkin's disease who was initially considered to have acute cholestatic hepatitis. Liver biopsy demonstrated prominent bile duct injury associated with a florid inflammatory reaction. These changes may represent an early stage of ductal injury, subsequently leading to vanishing bile duct syndrome, a recently documented mechanism of cholestasis in Hodgkin's disease.     

Case report: Paucity of interlobular bile ducts in Chinese children

Sixteen Chinese children with cholestasis since early infancy were diagnosed to have paucity of interlobular bile ducts (PILBD) or its equivalent. Twelve children belonged to the syndromic group of PILBD and four children belonged to the non-syndromic group. A definite histological diagnosis of bile duct paucity was established in only two children (aged 4 and 9 months) during the first percutaneous needle biopsy. In the remaining 14 children a varying degree of bile duct destruction was evident in the follow up percutaneous or wedge liver biopsies. The evolving changes were characterized by inflammatory infiltration near or at the ductal wall, the presence of dysmorphic ductules, the degeneration of ductal epithelia and a progressive decrease of interlobular bile ducts. Of 10 children who underwent laparotomy for definite diagnosis, kasai operation was performed in two of them. In the syndromic PILBD group, all children, including two paired siblings, had at least three of five major clinical features. Hypoplasia of the extrahepatic biliary tree was found in five children and atresia of the extrahepatic bile duct was found in one. Three of six children studied were shown, by polymerase chain reaction, to have cytomegalovirus infection in the liver. This study demonstrates that bile duct paucity is a result of progressive bile duct destruction. A definitive diagnosis is difficult to make in early infancy. Thus, the careful evaluation of extrahepatic features in cholestatic children and follow-up liver biopsies are indicated. Although the pathogenetic mechanism of PILBD is unknown, bile duct destruction is the common pathway leading to paucity of bile ducts irrespective of syndromic or non-syndromic types.     

Recurrent intrahepatic cholestasis of pregnancy and chain-like choledocholithiasis in a female patient with stop codon in the ABDC4-gene of the hepatobiliary phospholipid transporter

We report the case of a 40-years-old female patient with recurrent cholestatic liver disease who presented twice with severe intrahepatic cholestasis of pregnancy and pronounced choledocholithiasis between pregnancies. Bile duct stones were removed endoscopically and a laparoscopic cholecystectomy was performed after the second pregnancy. Liver histology revealed intrahepatic cholestasis with portal inflammation and fibrosis, resembling progressive familial intrahepatic cholestasis (PFIC). Molecular genetic studies identified the heterozygous mutation c.957C > T in the ABCB4 gene encoding the hepatobiliary phospholipid transporter. This is the first report of this mutation that introduces a stop codon in an index patient with intrahepatic cholestasis of pregnancy and multiple bile duct stones. In addition, we detected the ABCB11 polymorphism V 444A, which is associated with a decreased expression of the bile salt export pump. Whereas homozygous carriers of the ABCB4 mutation develop PFIC type 3, the heterozygous ABC transporter mutations represent genetic risk factors for cholelithiasis and recurrent cholestatic hepatitis upon challenge with oral contraceptives or during pregnancy. Of note, the patient presented with normal serum gamma-glutamyltranspeptidase activities during pregnancy-associated cholestatic episodes but normal liver enzymes after delivery, whereas choledocholithiasis was associated with high gamma-glutamyl transpeptidase levels. It is unknown whether ursodeoxycholic acid prevents cholestasis or gallstones in patients with ABCB4 deficiency.     

Hyperbilirubinemia and cholestatic liver injury in hepatitis C-infected liver transplant recipients

OBJECTIVE: A cholestatic pattern of liver injury has been observed in liver transplant recipients with rapidly progressive hepatitis C. We assessed the frequency and causes of cholestasis in hepatitis C-infected liver transplant patients, and evaluated the clinical and pathological course of those with cholestatic hepatitis C. METHODS: Sixty-nine sequential liver transplant recipients who had detectable hepatitis C viremia were studied retrospectively. Records and diagnostic tests were examined from patients who developed hyperbilirubinemia. RESULTS: Hyperbilirubinemia occurred in 33 of 69 (48%) hepatitis C-infected liver transplant patients. A thorough evaluation including review of clinical and laboratory data, ultrasound with Doppler, cholangiogram, and liver biopsy identified causes of hyperbilirubinemia other than hepatitis C in 26 of 33 patients. Seven patients developed cholestatic hepatitis C characterized by histological features of recurrent hepatitis C and cholestatic liver injury with ballooning of centrilobular hepatocytes, bile ductular proliferation, and canalicular cholestasis, in the absence of other causes of cholestasis. Five progressed rapidly to bridging fibrosis and two died of complications related to liver failure. Four patients with cholestatic hepatitis C showed extended survival after the onset of hyperbilirubinemia. CONCLUSIONS: 1) Hepatitis C is a relatively infrequent cause of cholestasis in liver transplant recipients. 2) The diagnosis of cholestatic hepatitis C requires a multimodality approach to exclude other causes of cholestasis. 3) Cholestatic hepatitis C ranges in severity and is not always associated with rapid development of graft failure, although significant histological abnormalities are frequent.     

A case of drug-induced ductopenia resulting in fatal biliary cirrhosis

ABSTRACT— A 50-year-old woman suffered from a diffuse skin rash, high fever and jaundice immediately after a second injection of glutathion and Stronger Neo-minophagen C which contains glycyrrhizin. Liver biopsy performed 11 months after the onset showed mild spotty hepatocyte necrosis, marked cholestasis in parenchyma, and some lymphocyte infiltration in the portal area. Interlobular bile ducts had undergone vacuolar degeneration or were absent in some portal tracts. In her hospital course, unremitting jaundice persisted and biliary cirrhosis developed with signs of portal hypertension; she died from liver failure 26 months after the onset. A liver specimen at her death revealed that most of the interlobular bile ducts had vanished. Based on the clinical course and pathology, drug-induced ductopenia, possibly due to an adverse reaction to glycyrrhizin, is the most likely diagnosis. While drug-related biliary cirrhosis is rarely fatal, this case presented an unusually rapid course of fatal biliary cirrhosis.     

Variant forms of cholestatic diseases involving small bile ducts in adults

OBJECTIVE: Cholestasis may result from diverse etiologies. We review chronic cholestatic disorders involving small intrahepatic bile ducts in the adult ambulatory care setting. Specifically, we discuss variant forms of primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) as well as other conditions that may present diagnostic and therapeutic difficulties. METHODS: We conducted a MEDLINE search of the literature (1981-1997) and reviewed the experiences at the Mayo Clinic. All articles were selected that discussed antimitochondrial antibody (AMA)-negative PBC, small-duct PSC (formerly pericholangitis), and idiopathic adulthood ductopenia. RESULTS: The most common chronic cholestatic liver diseases affecting adults are PBC and PSC. Patients without the hallmarks of either syndrome are diagnosed according to their clinical and histological characteristics. Autoimmune cholangitis is diagnosed if clinical and histological features are compatible with PBC but autoantibodies other than AMA are present. Isolated small duct PSC is diagnosed if patients have inflammatory bowel disease, biopsy features compatible with PSC, but a normal cholangiogram. If ductopenia (absence of interlobular bile ducts in small portal tracts) is found histologically in the absence of PSC, inflammatory bowel disease, and other specific cholestatic syndromes such as drug reaction or sarcoidosis, the most likely diagnosis is idiopathic adulthood ductopenia. CONCLUSIONS: Based on these definitions, an algorithm for diagnosis and therapy in patients with laboratory evidence of chronic cholestasis may be constructed, pending results of further investigations into the etiopathogenesis of these syndromes.     

Prolonged cholestasis and ductopenia associated with tenoxicam

Cholestatic liver diseases leading to progressive destruction of intra-hepatic bile ducts and ductopenia encompass multiple etiologies. Pathophysiology and natural history of drug-induced cholangiopathies remain unclear. We report a case of prolonged ductopenia attributed to Tenoxicam (Tilcotil o--a non-steroidal anti-inflammatory drug of the oxicam family) ingested at therapeutic dose. A 36 year-old male patient was admitted for jaundice and Lyell syndrome starting 1 week after the ingestion of Tenoxicam. Liver biopsy showed cholestasis, non-suppurative cholangitis and polymorphous inflammatory infiltrate of the portal tracts (round cells, macrophages an eosinophils). Treatment with ursodesoxycholic acid and cholestyramine was instituted and the patient was asymptomatic 1 year after. Three years later mild biological cholestasis persisted and ductopenia was evidenced on liver biopsy. In this report we found that: (1) The toxicity of tenoxicam was probably mediated by an immunoallergic mechanism (Lyell syndrome and eosinophils on histology); (2) ductopenia was secondary to inflammatory cholangitis. Factors responsible for this chronic evolution are still unknown (genetic predisposition, vascular factors, etc.); and (3) the presence of ductopenia contrasted with the "clinical recovery" of the disease suggesting accessory bile drainage by cholangioles or partial reconstruction of the biliary tree.     

Idiopathic adulthood ductopenia. A cause of chronic cholestatic liver disease and biliary cirrhosis

We describe three adult patients who had chronic cholestatic liver disease associated with unexplained loss of interlobular bile ducts; two of these patients eventually required orthotopic liver transplantation. We have named this condition 'idiopathic adulthood ductopenia' because (1) the etiology is unknown, (2) the age of the patients may be the only distinguishing feature between this newly described condition and neonatal or infantile nonsyndromatic paucity of intrahepatic bile ducts, and (3) morphologic demonstration of ductopenia is an indispensable finding. Our three patients, all males, had a negative drug history, absence of antimitochondrial antibodies, normal cholangiographic findings, and no evidence of inflammatory bowel disease. Idiopathic adulthood ductopenia may be a representation of (1) late onset of infantile paucity of intrahepatic bile ducts, (2) destructive viral cholangitis, and (3) isolated small-duct primary sclerosing cholangitis - that is, 'pericholangitis' unassociated with inflammatory bowel disease.     

Idiopathic biliary ductopenia in adults: a report of five cases

The clinical and pathological findings of five adult cases of idiopathic nonsyndromatic paucity of interlobular bile ducts are reported. Patients were 18-32 years old at the onset of the disease; four presented with pruritus and/or jaundice and one with bleeding of the esophageal varices. Two patients were siblings. Serum alkaline phosphatase counts ranged from 1 to 16 times the upper normal value, and total bilirubin counts ranged from 0.6 to 8.8 mg/dL (10 to 150 mumol/L). Initial liver biopsy showed portal and periportal fibrosis with cholangiolar proliferation and reduction in the number of interlobular bile ducts. Antimitochondrial antibodies were absent, and bile ducts were normal after opacification. The patients were observed for 3-11 years. Repeated liver biopsies in the five patients showed progression of the lesions, with development of biliary type cirrhosis in four. Two of the four patients with cirrhosis died of hepatic failure 3 and 11 years after onset of the disease. In the two other cases, liver transplantation was performed successfully. These cases suggest that chronic cholestasis with marked ductopenia resembling the nonsyndromatic paucity described in infancy and childhood may reveal itself at an adult age. This disorder, possibly familial, may rapidly progress to severe and even fatal liver disease and could be a new indication for liver transplantation.     

Effect of plasma exchange on the circulating IL-6 levels in a patient with fatal hemophagocytic syndrome associated with bile ductopenia

We report here the case of a patient suffering from hemophagocytic syndrome (HPS) associated with bile ductopenia. A 24-year old man was admitted after suffering fever, sore throat and general malaise for 7 days and jaundice for 2 days. Clinical studies showed hepatic dysfunction with hyperbilirubinemia. Epstein-Barr viral DNA from two bone marrow samples was detected. Bone marrow aspiration disclosed findings of HPS. Liver biopsy showed centrilobular cholestasis with lack of interlobular bile duct. Repeated therapeutic plasma exchange was effective for decreasing serum bilirubin and interleukin-6 levels. The patient received liver transplantation, however, he finally died of alveolar hemorrhage resulting from disseminated intravascular coagulation and acute rejection.     

The acute vanishing bile duct syndrome (acute irreversible rejection) after orthotopic liver transplantation

The acute vanishing bile duct syndrome can be defined as an irreversible, rejection-related condition that affects hepatic allografts within 100 days after orthotopic liver transplantation and whose presence requires retransplantation. We have observed the acute vanishing bile duct syndrome in 5 of 48 consecutive patients (approximately 10%) who underwent orthotopic liver transplantation. In 4 cases, the condition progressed relentlessly within approximately 7 to 11 weeks after orthotopic liver transplantation from mild rejection to severe rejection to acute vanishing bile duct syndrome. A fifth patient had severe rejection in the first week and required retransplantation after 17 days because of thrombotic venoocclusive disease complicating the acute vanishing bile duct syndrome. Clinically, signs of impending acute vanishing bile duct syndrome included abrupt onset of fever and jaundice and marked elevation of serum bilirubin and alkaline phosphatase levels which persisted despite antirejection treatment. Biopsy specimens revealed destructive cholangitis (rejection cholangitis), ductopenia, and, if retransplantation was delayed, presence of noninflammatory, "burnt-out" portal tracts without bile ducts. We recommend to base the diagnosis of acute vanishing bile duct syndrome on documentation of severe ductopenia in at least 20 portal tracts which may require several consecutive needle biopsies. Rejection arteriopathy which was found in 3 of our 5 cases might have been another important diagnostic clue but could not be recognized prior to retransplantation. The pathogenesis of acute vanishing bile duct syndrome is not clear; until the condition had manifested itself, we found no qualitative differences between acute reversible and irreversible rejection.(ABSTRACT TRUNCATED AT 250 WORDS)     

Importance of liver puncture biopsy and endoscopic retrograde cholangiography in patients with chronic anicteric unexplained cholestasis. A retrospective study in 79 patients]

AIM: To determine the diagnostic value of systematic liver needle biopsy and endoscopic retrograde cholangiography in patients with unexplained chronic anicteric cholestasis. METHODS: Seventy nine patients presented with anicteric cholestasis for over 6 months as defined by: a concomitant increase in at least 2 of 3 cholestatic enzymes (GGT, alkaline phosphatase, 5'nucleotidase); a low cytolytic ratio (ALT/AP (xN/xN) < or = 5); and negative test results (normal ultrasound scan; no antimitochondrial antibodies, viral, drug-induced, or toxic hepatitis, or known ulcerative cholitis). Based on liver biopsy and endoscopic retrograde cholangiography, 5 groups were determined; group A: normal liver biopsy and endoscopic retrograde cholangiography; group B: primary sclerosing cholangitis with histological biliary lesions; group C: primary sclerosing cholangitis with normal histology; group D: histologic biliary lesions alone; group E: other (aspecific histologic lesions, isolated anomalies of intrahepatic bile ducts on endoscopic retrograde cholangiography). RESULTS: Diagnosis of cholestasis was fortuitous in 43% of cases. Group A: 5 patients had normal liver biopsy and endoscopic retrograde cholangiography; group B (10 patients): 5 with destructive cholangitis, 5 with degenerative cholangitis, associated with portal fibrosis in 90%; group C: none of the patients had primary sclerosing cholangitis with normal histology; group D: 39 patients {idiopathic ductopenia (1), Caroli's disease (1), benign recurrent cholestasis (1), regenerative nodular hyperplasia (4), destructive cholangitis without ductopenia (7), degenerative cholangitis (15), ductular proliferation (10)}; group E: 24 patients with aspecific histologic lesions, and one patient with isolated anomalies of the intrahepatic bile ducts on endoscopic retrograde cholangiography. CONCLUSIONS: In the present population: a) 13% presented with intense cholangitis and primary sclerosing cholangitis on endoscopic retrograde cholangiography; b) 49% presented with various histologic biliary lesions without primary sclerosing cholangitis. We conclude that in chronic anicteric cholestasis of unexplained origin, first choice work-up should include liver biopsy, and endoscopic retrograde cholangiography should only be performed when intense histologic cholangitis is observed.
