Idiopathic thrombocytopenic purpura in a liver transplant recipient with previous primary biliary cirrhosis

The loss of immunotolerance has been implicated in the pathogenesis of both primary biliary cirrhosis (PBC) and idiopathic, immune-mediated thrombocytopenic purpura (ITP). An association between these two autoimmune diseases has been well described. We describe a 41-year-old woman in whom ITP developed 457 days after liver transplantation for PBC while receiving immunosuppressive medications sufficient to maintain allograft function. Our case report, the first to describe post-transplant ITP in association with PBC, demonstrates the persistence of the underlying immune dysregulation of PBC after transplantation. The practice of decreasing the dosage of immunosuppressive medication to maintenance levels after transplantation may unmask the effects of this defect in immunotolerance.     

Genotype/phenotype correlation in affected individuals of a family with a deletion of the entire coding sequence of the connexin 32 gene

A patient with idiopathic thrombocytopenic purpura (ITP) developed T-cell lymphoma while undergoing steroid therapy. We examined the relationship between the patient's serum thrombopoietin (Tpo) level, platelet count, megakaryocyte number and CFU-Meg number during the second 5 d course of chemotherapy for lymphoma in which megakaryopoiesis switched from ITP phase to amegakaryocytic phase. The patient's platelet count was temporarily elevated but CFU-Meg numbers were markedly suppressed, and megakaryocyte numbers were decreased in this period, whereas serum Tpo level was not suppressed despite an increased platelet count, indicating that serum Tpo level is mainly regulated by megakaryocyte mass.     

Primary biliary cirrhosis and systemic lupus erythematosus. A new case report

Systemic lupus erythematosus and primary biliary cirrhosis are two autoimmune disorders that rarely occur in the same patient. Ten well-documented cases have been reported to date. We add the case of a woman who was diagnosed with systemic lupus erythematosus at 54 years of age then with primary biliary cirrhosis 18 years later. Interestingly, primary biliary cirrhosis antedated the systemic lupus erythematosus in all the other reported cases. The possibility that a patient may develop more than one autoimmune disorder should be borne in mind.     

Hepatocellular carcinoma complicating biliary cirrhosis caused by biliary atresia: report of a case

A case of hepatocellular carcinoma complicating biliary cirrhosis caused by biliary atresia is reported. The patient had persistent severe jaundice with hepatosplenomegaly. A liver tumor was suspected because of the elevated serum alpha-fetoprotein and was shown by ultrasonography at 6 years of age. The tumor was treated with percutaneous ethanol injection therapy (PEIT). Nine months after initiation of PEIT, the patient died of massive bleeding from a metastatic tumor.     

Bread staling. Simultaneous effect of bacterial alpha-amylase and emulsifier on firmness and pasting properties of bread crumbs++

Late recurrent primary biliary cirrhosis (PBC) following orthotopic liver transplant remains a controversial topic. The first documented case of recurrence occurring in 16 patients transplanted for PBC and followed at the authors' institution for longer than one year is presented. A 54-year-old man transplanted for PBC developed a cholestatic pattern of enzyme elevation on post-transplant day (PTD) 1305. Repeat antimitochondrial antibody was strongly positive (1:300 to 1:400). A liver biopsy revealed severe bile duct damage, lymphocytic cholangitis, focal periductal noncaseating granuloma and minimal endotheliitis. Recurrent PBC was diagnosed. At the time of orthotopic liver transplant this patient received induction immunosuppression with OKT3 crossed over to cyclosporine (CsA), azathioprine (AZA) and prednisone. AZA was discontinued early and maintenance CsA tapered to a target trough level of 150 to 200 ng/mL by PTD 365. Prednisone was withdrawn by PTD 664. CsA levels during PTDs 1225 to 1305 (before elevation of hepatobiliary enzymes) were below target at 114 to 166 ng/mL. Of the 16 patients, all but three were maintained on CsA, AZA and prednisone. One was on CsA (trough levels on target) and AZA; the other two, including the patient with recurrent PBC, were on CsA only. The trough CsA level of the patient without recurrent PBC has been within the target range. The authors speculate that the underlying defect in immunoregulation in PBC persists post-transplant and that in the patient without recurrent PBC this defect was unmasked by lowered maintenance immunosuppression--allowing recurrence of PBC in a previously stable liver allograft.     

Hepatocellular carcinoma in primary biliary cirrhosis: a case report and review of the Japanese literature

We present a 66 year-old woman in the cirrhotic stage of primary biliary cirrhosis (PBC), who developed hepatocellular carcinoma (HCC). All serological tests for hepatitis B virus (HBV) and hepatitis C virus (HCV) were negative. We surveyed 16 reported cases (13 females and 3 males) of PBC associated with HCC in Japan. The presence of HCV RNA was determined by the polymerase chain reaction in all of the patients, 3 of whom (19%) were HCV RNA-positive. Although patients with PBC rarely develop HCC, it is suggested that HCV infection may play a minor role in the development of HCC in Japanese patients with PBC.     

Enhanced apoptosis relates to bile duct loss in primary biliary cirrhosis

Primary biliary cirrhosis (PBC) is characterized by an immune-mediated destruction of intrahepatic small bile ducts. Apoptosis, a unique pattern of cell death, has been suggested to be responsible for the biliary destruction in PBC. To address this issue, we attempted to detect the apoptosis of biliary epithelial cells by in situ nick-end labeling and by the expression of apoptosis-related proteins using immunohistochemistry in patients with various hepatobiliary diseases, including PBC. The data was noteworthy for several reasons. First, apoptosis was occasionally detected on biliary cells in all liver specimens; however, the positive rate was high in PBC and relatively low in other livers. Strong expression of CD95 was frequently observed in the epithelial cells of the injured bile ducts of PBC, which accompanied high intensity CD95 ligand-expressing mononuclear cells. Perforin and granzyme B immunoreactivities were occasionally found on the bile ducts in control liver diseases as well as PBC, but granzyme B-positive biliary cells were prominent in PBC. In contrast, Lewis Y expression, as detected using BM-1 antibody, was consistently present in the injured bile ducts of PBC. These data suggest that apoptosis, via the perforin/granzyme B pathway, may be associated with the degrading fraction of cell cycle regulation in the small-sized biliary tree under physiological and pathological liver conditions. Moreover, enhanced apoptosis, mediated by CD95/CD95 ligand interaction, may contribute to the bile duct injury and loss observed in PBC.     

Disseminated histoplasmosis and Wegener's granulomatosis

Disseminated histoplasmosis is an unusual complication in endemic areas and has been reported in patients with an immunodeficient state, either from human immunodeficiency virus (HIV) infection or transplantation. In the non-HIV population, rare cases of disseminated histoplasmosis have been reported in patients with leukemia and Hodgkin's disease and patients receiving steroid therapy for various diseases. We report a case of disseminated histoplasmosis in a patient with Wegener's granulomatosis.     

Two cases of systemic lupus erythematosus associated with fatty liver and Basedow's disease

We present two cases of systemic lupus erythematosus (SLE) associated with both Basedow's disease and fatty liver. The first case is a 46-year-old Japanese female who was admitted because of high fever and general fatigue. She had been diagnosed as having Basedow's disease and treated with thiamazole for over 4 years. Since thiamazole-induced lupus was unlikely because of high titer anti-nuclear antibody and anti-DNA antibody and low levels of complements, a diagnosis of SLE was made. The upper abdominal ultrasound study and the specimen obtained by liver biopsy performed before initiating steroid therapy demonstrated marked fatty liver. SLE itself is considered as an etiology of fatty liver in this case. The second case was a 25-year-old Japanese female with SLE. She had been treated with prednisolone for 13 years and was complicated with Basedow's disease 10 years later. Fatty liver was also demonstrated in this patient on ultrasonography, and was thought to be resulted from long-term steroid hormone administration.     

Natural history of early primary biliary cirrhosis

BACKGROUND: In 1986, we reported a group of 29 patients who were positive in serum for antimitochondrial antibody (AMA), the disease-specific marker for primary biliary cirrhosis (PBC), but who had normal liver function test results and no symptoms of liver disease. However, liver histology was diagnostic or compatible with PBC in 24 patients and normal in only two. The aims of this 10-year follow-up study were to establish whether patients with AMA have very early PBC, to assess the outlook for such patients, and to follow the progression of the disease. METHODS: All patients were assessed every year at our PBC clinic: records were reviewed, cause of death verified when applicable, and current clinical and biochemical data collected, including repeat liver histology as indicated. Serum samples from the original study were located. Original and follow-up serum samples were tested by ELISA for E2 components of pyruvate dehydrogenase complex and 2-oxoglutarate dehydrogenase complex. FINDINGS: Five patients died during follow-up; no deaths were attributable to liver disease. Median follow-up of patients who survived was 17.8 years (range 11.0-23.9) from first-detected AMA to the last follow-up review. Overall, 22 (76%) developed symptoms of PBC and 24 (83%) had liver function tests persistently showing cholestasis. Repeat liver biopsy samples were obtained from ten patients; among these patients PBC progressed from Scheuer grade 1 to grade 2 in two and from grade 1 to grade 3 in two. No patient developed clinically apparent cirrhosis. ELISA of baseline serum samples from 27 patients was positive in 21, all of whom had original liver histology compatible with or diagnostic of PBC. Of the six patients who tested negative, only one had an original liver biopsy sample that was compatible with PBC. INTERPRETATION: This study confirms that before the advent of any clinical or biomedical indications, individuals positive for AMA do have PBC. This finding extends the natural history of PBC back in some cases for many years. What determines the eventual progression to biochemically and clinically apparent disease is not yet understood. During our study no patient developed clinically apparent portal hypertension or cirrhosis. Thus, although the finding of a solitary persistently raised AMA is confirmation of a diagnosis of PBC, patients with AMA but no other signs or symptoms of PBC seem to have slow progression of the disease.     

A trial of the use of Maldroxal in treating patients with duodenal peptic ulcer

A 67 year old man presented with non-invasive thymoma, associated aplastic anemia and important hypogammaglobulinemia; the postoperative course has been characterized, three months later, by thrombocytopenia (kept under control with steroid therapy) and, two years later, by squamous lung cancer, not susceptible of surgical treatment. The patient died five years after operation because of progression of the lung cancer. Anemia improved only partially after operation; there where no effects on hypogammaglobulinemia. Thymoma has been reported in literature in 50% of patients with aplastic anemia, 7-13% of adult patients with hypogammaglobulinemia is affected by thymoma, in 21% of patients that presented with thymoma other tumors have been discovered through clinical history.     

Flow injection amperometric determination of L-dopa, epinephrine or dopamine in pharmaceutical preparations

OBJECTIVE: The association of systemic lupus erythematosus (SLE) and multiple myeloma (MM) is an uncommon event. We report the relapse of SLE in a patient with a previous history of MM, treated with chemotherapy and, subsequently, with alpha-2b interferon (alpha-2b IFN) as a maintenance therapy. The case is discussed in light of past relevant literature. METHODS: The history and clinical, laboratory and radiographic findings of the patient, as well as the subsequent therapeutic approach are discussed. In our review of the literature, journal articles are identified by Medline search. RESULTS: We describe the case of a woman who developed a multiple myeloma 14 years after a diagnosis of SLE. A careful literature review confirms that the association of these two diseases has been reported only in a few cases. When the plasma cell neoplasia occurred, SLE had been quiescent for several years; the patient was treated with prednisone-melphalan and, subsequently, with alpha-2b IFN as a maintenance therapy. On admission to our department, SLE was in a relapse phase, probably because of IFN treatment. The disease was poorly responsive to steroid therapy and required the use of cytotoxic drugs. CONCLUSIONS: The coexistence of SLE and MM is very rare and the possible pathogenetic mechanisms underlying this association remain unclear. The use of interferon in a patient with an autoimmune disease always invites caution.     

An EIA method on single donor solubilized HLA antigens for the identification of anti-HLA antibodies

Primary biliary cirrhosis (PBC) is an immunologically mediated disease in which activated T lymphocytes attack and destroy epithelial cells in the small intralobular bile ducts of genetically susceptible patients. This article reviews the results of treatment of PBC with immunomodulatory agents. Results with drugs such as glucocorticoids, azathioprine, and chlorambucil have been disappointing because of either limited efficacy (azathioprine), toxicity (chlorambucil), or both (glucocorticoids). Colchicine improved tests of liver function in three prospective studies and was associated with improved survival for up to 4 years. However, survival benefits were lost at 8 years. Colchicine appears to slow the rate of progression of PBC but not to stop it. Preliminary results suggest that colchicine may have synergistic effects if used together with ursodeoxycholic acid, particularly in patients who are only partially responsive to ursodeoxycholic acid. Results with cyclosporine have been disappointing because of limited efficacy and predictable toxicity. The modest improvement in tests of liver function and survival are counterbalanced by the development of hypertension in some and worsening renal function in most. There is little beneficial effect on symptoms or histology. Results with methotrexate are promising. There are improvements in symptoms and tests of liver function that are equal to those seen with ursodeoxycholic acid and significant improvement in liver histology. Some patients, particularly those with striking inflammation and granulomas in portal triads, appear to have achieved sustained remission while on methotrexate. The effects of methotrexate are additive to those of ursodeoxycholic acid in patients whose blood tests have responded only partially to ursodeoxycholic acid. The most effective treatment of PBC will most likely use a combination of drugs such as ursodeoxycholic acid, colchicine, and methotrexate.     

Antimitochondrial autoantibodies in anti-glomerular basement membrane disease

Anti-glomerular basement membrane (GBM) disease is characterized by the production of an autoantibody with very restricted specificity, with no evidence of polyclonal B cell activation. It was therefore surprising to find that in a solid-phase ELISA a proportion of anti-GBM sera showed significant binding to pyruvate dehydrogenase (PDH), a reactivity usually associated with the antimitochondrial autoantibodies (AMA) found in primary biliary cirrhosis (PBC). The specificity of this reactivity was confirmed by inhibition and competition experiments. The AMA found in anti-GBM sera were of much lower affinity than those found in PBC sera, and recognized a more restricted set of species (mainly the 55-kD and occasionally the 74-kD component of PDH). However, it was possible to block the binding in a Western blot of an anti-GBM serum to both the 55-kD and 74-kD species with F(ab')2 fragments prepared from a PBC serum. Although AMA have been found in diseases other than PBC, such diseases have usually been characterized by polyclonal B cell activation. The stimulus to the production of AMA in anti-GBM disease, and their significance in pathogenesis (if any), are unknown.     

Adaptive response in embryogenesis: I. Dose and timing of radiation for reduction of prenatal death and congenital malformation during the late period of organogenesis

BACKGROUND: Coexistent primary biliary cirrhosis (PBC) and coeliac disease has been recorded but the association has not been systematically studied. AIMS: To determine relative prevalences of PBC and coeliac disease in a defined population over a 12 year period. PATIENTS AND METHODS: All patients with PBC or coeliac disease in a stable population of 250,000 in South Wales were identified from a clinical register and laboratory records. RESULTS: Sixty seven patients with PBC and 143 patients with coeliac disease have been diagnosed and followed over a median of 86 (4-135) months; point prevalences in 1996 were 20 per 100,000 for PBC and 54 per 100,000 for coeliac disease. PBC in patients with coeliac disease was sought by investigating abnormal liver function tests. Ten (7%) had persistent abnormalities and three had PBC. Coeliac disease in patients with PBC was sought by investigating malabsorption, haematinic deficiency, positive antigliadin antibody, or coeliac disease family history. Eleven patients underwent duodenal biopsy revealing one further coeliac disease case. Four patients (three women have both conditions giving a point prevalence for patients with both conditions of 1.6 per 100,000 (95% confidence limits 0.44 to 4.1 per 100,000). Prevalence of PBC in patients with coeliac disease was 3% and of coeliac disease in patients with PBC was 6%. CONCLUSION: A 12 year study of a stable 250,000 population revealed a relative prevalence of PBC in 3% of 143 patients with coeliac disease and of coeliac disease in 6% of 67 patients with PBC. PBC and coeliac disease are therefore associated. Screening for PBC in patients with coeliac disease using antimitochondrial antibody testing and screening for coeliac disease in patients with PBC with antigliadin antibody testing or duodenal biopsy are recommended.     

Clenbuterol and anabolic steroids: a previously unreported cause of myocardial infarction with normal coronary arteriograms

During the last 10 years, several cases of myocardial infarction associated with anabolic steroid use have been reported. Postulated mechanisms to explain this association have included changes in lipid levels, the fibrinolytic system, and platelet aggregation. Clenbuterol is a beta 2-agonist with anabolic properties that has not been seen previously with myocardial infarction. We report a case of myocardial infarction in an otherwise healthy 26-year-old body-builder who recently used clenbuterol and anabolic steroids. In this case, synergistic effects of the two agents seem likely to have played a role in the infarct. The normal coronary arteriograms before any anticoagulant or thrombolytic therapy strongly suggest coronary spasm as the mechanism of the infarct.     

Induction of apoptosis in human leukemia K562 cells by alpha-anordrin

The apparent coexistence of primary biliary cirrhosis (PBC) and autoimmune hepatitis in the same patient raises unresolved problems for nosology and therapy. These are exemplified by a 45-year-old Japanese woman with overlapping clinical, serological and histological features of autoimmune cholangitis and autoimmune hepatitis. The classical serological test for PBC, antimitochondrial antibody (AMA) by immunofluorescence, was atypical. By immunoblotting there was reactivity with one of the enzymes of the 2-oxo-acid dehydrogenase complex (2-OADC) family, now recognized as autoantigens responsible for AMA reactivity. Also there was reactivity by immunofluorescence for antinuclear antibodies (ANA), one showing the typical speckled pattern of anti-Sp-100 and the other the peripheral pattern of antinuclear membrane antibody, both with titres > 10(6). There was also a positive result to the lupus erythematosus (LE) cell test. Treatment with ursodeoxycholic acid was beneficial. Thus while the clinical presentation suggested the overlapping syndrome of autoimmune hepatitis and PBC, PBC eventually proved to be the likely diagnosis. We suggest that apparent cases of overlapping PBC-autoimmune cholangitis-hepatitis syndromes, after detailed testing, will mostly align with PBC.     

Evans syndrome after autologous bone marrow transplant for recurrent Hodgkin's disease

The association of immune thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia (AIHA) with Hodgkin's disease has been known for many years. Autoimmune cytopenia has also been described in patients that have undergone allogeneic or autologous bone marrow transplantation. We report a rare case of Evans syndrome in a patient 3 years after autologous bone marrow transplantation for recurrent Hodgkin's disease.     

Successful steroid treatment of idiopathic thrombocytopenic purpura after orthotopic liver transplantation for primary biliary cirrhosis

Primary biliary cirrhosis (PBC) is an autoimmune disease of the liver frequently associated with extrahepatic autoimmune phenomena. Specific antibodies against platelet glycoproteins may play an important role in the pathogenesis of thrombocytopenia associated with PBC. This is the first report of life-threatening idiopathic thrombocytopenic purpura successfully treated with steroids in a 62-yr-old woman 2 yr after liver transplantation for PBC.     

Antibodies to mycobacterial 65-kD heat shock protein cross-react with the main mitochondrial antigens in patients with primary biliary cirrhosis

Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease associated with autoimmune disorders. The aetiology is unknown, although it has been suggested that the disease may be related to infectious agents. Previous studies revealed that sera from patients with PBC react against Mycobacterium gordonae. This specific reactivity, characterized by a recognition of two membrane polypeptides of 70-65 and 55 kD, cross-react with the two major mitochondrial autoantigens of PBC. As the most immunogenic components of mycobacteria are the heat shock proteins (hsp), which have been associated with autoimmunity, this study has been undertaken to characterize whether the reacting polypeptides in PBC are hsp from M. gordonae. Cultures of M. gordonae were incubated at 37 degrees C and 46 degrees C before sonication, protein extraction and separation by SDS-PAGE. Exposure of M. gordonae to heat shock treatment resulted in membrane protein overexpression, similar to the 70-65-kD polypeptide recognized by the sera from patients with PBC. Immunoprecipitation assays with a monoclonal antibody directed against the Hsp65 kD of mycobacteria and with sera from patients with PBC revealed similar reacting profiles characterized by the precipitation of the overexpressed 65-kD polypeptide from M. gordonae. Competitive immunoblotting showed that binding of the monoclonal antibody to the Hsp65 kD protein was prevented by preincubation with sera from patients with PBC, but not with sera from healthy subjects. Furthermore, monoclonal antibody to the Hsp65 kD protein recognized the main mitochondrial autoantigens of PBC (PDH-E2 and BCKDH-E2). These data indicate the existence of cross-reacting epitopes contained on M. gordonae Hsp65 kD and the main mitochondrial antigens in patients with PBC.
