RESUMO

RESUMEN Introducción: La cirrosis hepática constituye la etapa final de muchas enfermedades del hígado. Objetivo: Determinar las características epidemiológicas y clínicas de pacientes con cirrosis hepática. Métodos: Se realizó una investigación descriptiva, retrospectiva, con datos de archivo, de 57 pacientes cirróticos. Se excluyeron aquellos con datos insuficientes en la historia clínica. Las variables analizadas fueron: edad, sexo, etiología, modo de diagnóstico, comorbilidades, manifestaciones endoscópicas de la hipertensión portal, complicaciones, estadios de la enfermedad según D'Amico y clasificación de Child-Pugh. Para el análisis de los resultados se emplearon técnicas de la estadística descriptiva. Resultados: Hubo 19 pacientes (33,3 %) en el grupo de edad entre 60 y 69 años; 31 (54,4 %) mujeres y 26 (45,6 %) hombres. El virus de la hepatitis C fue encontrado en 21 pacientes (36,8 %). El 96,4 % de los enfermos se diagnosticaron mediante ecografía abdominal; 12 (21,1 %) presentaron ascitis y 38 (66,6 %) manifestaciones endoscópicas de hipertensión portal. En estadio 4 de D'Amico estaban 20 (35 %) enfermos y 26 (45,6 %) en estadio de Child-Pugh A; 24 (42,1 %) en Child-Pugh B y 7 (12,3 %) en Child-Pugh C. Conclusiones: La cirrosis hepática predomina en la séptima década de la vida, en el sexo femenino. Prevalece el ultrasonido abdominal como modo de diagnóstico. Las causas más frecuentes son el virus de hepatitis C y el alcoholismo. La ascitis es la complicación que más se presenta. La mayoría de los pacientes muestran signos de hipertensión portal. Predominan las formas no compensadas de la enfermedad.

ABSTRACT Introduction: Liver cirrhosis is the end stage of many liver diseases. Objective: To determine the epidemiological and clinical characteristics of patients with liver cirrhosis. Results: There were 19 patients (33.3%) in the age group between 60 and 69 years; 31 (54,4 %) women and 26 (45,6 %) men. Hepatitis C virus was found in 21 patients (36,8 %). 96,4 % of the patients were diagnosed by abdominal ultrasound; 12 (21,1 %) presented ascites and 38 (66,6 %) endoscopic manifestations of portal hypertension. In D'Amico stage 4 there were 20 (35 %) patients and 26 (45,6 %) in Child-Pugh A stage; 24 (42,1 %) in Child-Pugh B and 7 (12,3 %) in Child-Pugh C. Conclusions: Liver cirrhosis predominates in the seventh decade of life, in females. Abdominal ultrasound prevails as a diagnostic mode. The most common causes are hepatitis C virus and alcoholism. Ascites is the most common complication. Most patients present with signs of portal hypertension. Uncompensated forms of the disease predominate.

RESUMO

ABSTRACT Primary biliary cirrhosis is a rare progressive autoimmune liver disease that causes chronic cholestasis. Of patients with primary biliary cirrhosis, 75% develop secondary Sjogren syndrome and could develop vitamin A deficiency. Here, we report the case of a patient with primary biliary cirrhosis who developed a secondary Sjogren syndrome and vitamin A deficiency, which led to severe and unusual eye involvement with multiple and recurrent spontaneous corneal perforations. Corneal perforations in patients with primary biliary cirrhosis and secondary Sjogren syndrome are rare but devastating complications, in contrast to other eye clinical manifestations of the disease.

RESUMO A cirrose biliar primária é uma doença hepática autoimune progressiva rara que causa colestase crônica. 75% dos pacientes com Cirrose Biliar Primária desenvolvem Síndrome de Sjögren Secundária, e podem também desenvolver deficiência de vitamina A. Aqui, relatamos um paciente com Cirrose Biliar Primária que desenvolveu Síndrome de Sjögren Secundária e deficiência de vitamina A, levando a envolvimento ocular grave e incomum com perfurações espontâneas múltiplas e recorrentes da córnea. Perfurações da córnea em pacientes com Cirrose Biliar Primária e Síndrome de Sjögren Secundária são complicações raras, mas devastadoras, em contraste com outras manifestações clínicas oculares da doença.

RESUMO

Primary biliary cholangitis (PBC) is an autoimmune liver disease associated with altered lipoprotein metabolism, mainly cholesterol. Hypercholesterolaemia, a major modifiable risk factor for cardiovascular disease in the general population, occurs in 75%-95% of individuals with PBC. The impact of hypercholesterolaemia on cardiovascular risk in PBC, however, is controversial. Previous data have shown that hypercholesterolaemia in PBC is not always associated with an increase in cardiovascular events. However, patients with PBC with cardiovascular risk factors may still warrant cholesterol-lowering therapy. Treatment of hypercholesterolaemia in PBC poses unique challenges among primary care providers due to concerns of hepatotoxicity associated with cholesterol-lowering medications. This review summarises the current understanding of the pathophysiology of hypercholesterolaemia in PBC and its pertinent cardiovascular risk. We will also discuss indications for treatment and the efficacy and safety of available agents for hypercholesterolaemia in PBC.

RESUMO

INTRODUCTION: Several groups have reported associations of primary biliary cholangitis with other autoimmune entities, particularly Sjögren's syndrome and hypothyroidism. Its prevalence and characteristics in Mexican patients is unknown. AIM: To determine the frequency and characteristics of autoimmune diseases in a Mexican cohort of patients with primary biliary cholangitis. MATERIALS AND METHODS: The medical records of patients that presented with primary biliary cholangitis within the time frame of 2005 and 2012 were reviewed and assessed for other autoimmune diseases. RESULTS: Seventy-eight patients, 75 women and 3 men, were included. Their mean age was 55.8 years. Seventy-three cases had positive antimitochondrial antibodies (94.8%) and disease was confirmed in 5 through liver biopsy. Five patients (8%) had anti-smooth muscle antibodies and 55/78 (70.5%) had antinuclear antibodies by indirect immunofluorescence. Forty-nine patients (62.8%) were positive for an autoimmune disease other than primary biliary cholangitis. Among those, 20 patients had one associated disease, 14 had 2, and 15 patients had 3 concomitant diseases. They included: Sjögren's syndrome in 23/78 patients (29.5%), dysthyroidism in 21/78 cases (26.9%), Raynaud syndrome in 11/78 (14.1%), CREST syndrome in 9/78 patients (11.4%), rheumatoid arthritis in 6/78 patients (7.7%), vitiligo in 5/78 (6.4%), scleroderma in 4/78 patients (5.1%), and other diseases in 8 patients. In 12/78 patients (15.4%), there was a documented family background of autoimmune disease. CONCLUSIONS: The presence of autoimmune associations in our cohort was frequent, and similar in characteristics to the information reported by other groups. The clinical implications of those findings remain to be determined.

RESUMO

El síndrome de Reynolds, se define como cirrosis biliar primaria en pacientes con esclerodermia; este síndrome debe ser sospechado en aquellos pacientes que desarrollen un patrón colestásico. Se reporta una paciente con antecedente de esclerodermia que se presenta con ictericia, a quien se le confirma con estudios inmunológicos y biopsia hepática, el diagnóstico de cirrosis biliar prima­ ria (ahora se denomina colangitis biliar primaria). Se ordena ácido ursodesoxicólico 15mg/día.

Reynolds syndrome is defined as primary biliary cirrhosis in patients with scleroderma; this syndro­me should be suspected in those patients who develop a cholesteric pattern. We report a patient with scleroderma who presented with jaundice. After immunological and liver biopsy, a diagnosis of Primary Biliary Cholangiopathy (new name) was confirmed. Ursodeoxycholic acid 15mg / day was prescribed

RESUMO

BACKGROUND: Autoimmune hepatitis (AIH) with characteristics of primary biliary cholangitis (PBC) is known as overlap syndrome. Its prevalence and prognosis have not yet been determined comparatively with AIH. METHODS: A retrospective cohort study was conducted comparing patients diagnosed with AIH and AIH-PBC overlap syndrome, followed-up for seven years in a university hospital in Colombia, until 31 December 2016. RESULTS: A total of 210 patients were included (195 women, mean age 48.5years). Of these, 32 (15.2%) had AIH-PBC overlap syndrome. At diagnosis, no significant differences were found by demographic profile, positive autoantibodies (ANA, ASMA), except AMA (81.2% vs 3.9%, P<.001), and histological grade of fibrosis. The most frequent clinical presentations were nonspecific symptoms in AIH-PBC and acute hepatitis in AIH. Although there were no significant differences, AIH showed a greater biochemical response to immunosuppressive management (87.3% vs 74.2%, P=.061) and a greater number of relapses in those who achieved partial or complete remission during treatment (12.4% vs 7.63%; P=.727). Patients with AIH-PBC had greater progression to cirrhosis (22.2% vs 13.1%, P=.038), even in those who achieved partial or complete biochemical remission without relapse, with greater indication of orthotopic liver transplantation (P=.009), but not retransplantation (P=.183); there were no differences in mortality. CONCLUSIONS: AIH-PBC overlap syndrome accounts for a significant proportion of patients with AIH, with greater progression to cirrhosis, indication of liver transplantation and possibly retransplantation. This higher risk of adverse outcomes suggests closer monitoring, probably with follow-up until confirmed histopathological remission.

RESUMO

BACKGROUND: Autoimmune liver diseases (AILD) comprise a set of entities characterized by tissue damage as a result of the loss of self-tolerance. There are few reports of AILD from Caribbean countries. OBJECTIVES: The aim of our study was to investigate the clinical patterns, laboratory findings, and immunologic features, treatment responses, and prognoses of AILD in adult patients at a Cuban tertiary referral center. METHODS: A prospective study was conducted at the National Institute of Gastroenterology in Havana, Cuba, from May 2012 to April 2016. Clinical, immunologic, and histologic features of autoimmune hepatitis (AIH), primary biliary cirrhosis, AIH/primary biliary cirrhosis overlap syndrome, autoimmune cholangiopathy, and primary sclerosing cholangitis were recorded. Response to therapy was assessed by serum alanine aminotransferase and bilirubin levels at 3, 6, 12, and 24 months after treatment initiation. RESULTS: Of the 106 patients included in the study, 85.5% were women. The median age at presentation was 47 years. AIH was the most common AILD and was diagnosed in 60 patients (56.6%), 55 of whom had type 1 AIH. Primary biliary cirrhosis was diagnosed in 22 patients (20.7%), overlap syndrome in 16 patients (15%), autoimmune cholangiopathy in 5 patients (4.71%), and PSC in 3 patients (2.8%). Most patients were symptomatic; 48 patients (45.2%) presented with liver cirrhosis, 14.5% of whom had decompensated cirrhosis. Follow-up of treatment was between 6 and 24 months. Prednisone monotherapy was used in 22 AIH patients (36.6%) and a combination of prednisone and azathioprine was used in 28 (46.6%) AIH patients. Response to treatment was seen in 41 AIH patients (68.3%), 33 of whom (55%) had a complete response and 8 of whom (24.2%) relapsed after 12 months of maintenance therapy. No or incomplete response to treatment was seen in 18 patients (30%). In 46 patients with autoimmune cholestasis, ursodeoxycholic acid was used as monotherapy in 25 patients (54.3%). CONCLUSIONS: The clinical profile of AILD in a sample of the Cuban population is similar to that reported in South areas (Developing countries). AIH was more frequent than PBC, and usually presented with advanced liver disease that responded poorly to treatment.

RESUMO

Resumen La esclerosis sistèmica (esclerodermia) es la enfermedad reumática autoinmunitaria asociada más comúnmente con cirrosis biliar primaria. La relación entre la forma cutánea limitada de esclerosis sistémica y cirrosis biliar primaria se describió en el decenio de 1970. Se comunica el caso de una paciente de 65 años de edad con esclerosis sistémica cutánea limitada de larga evolución, positiva a anticuerpos contra centròmero y mitocondria. La biopsia hepática confirmó cirrosis biliar primaria en fase portal (estadio 1).

Abstract Systemic sclerosis (scleroderma) is an autoimmune rheumatic disease most commonly associated with primary biliary cirrhosis. The relationship between limited cutaneous systemic sclerosis and primary biliary cirrhosis was first described in the early 1970's decade. The case of 65 year-old woman with limited cutaneous systemic sclerosis and primary biliary cirrhosis seropositive for anticentromere and anti-mitochondrial antibodies is reported. Liver biopsy confirmed primary biliary cirrhosis in stage 1.

RESUMO

La sobrevida de los pacientes postrasplante hepático supera el 90% al año y el 75% a los 5 años. Entender las causas de pérdida del injerto, o inclusive la muerte del paciente, es esencial para mejorar aún más los resultados a largo plazo. La evaluación de las biopsias hepáticas tiene un papel importante en la explicación y manejo de la disfunción del injerto de hígado, que ocurre después del primer año del trasplante. La interpretación de estas biopsias puede ser muy difícil, en especial por la alta incidencia de enfermedades recurrentes que pueden mostrar un cuadro clínico y unas características histopatológicas que semejan varias condiciones, especialmente cuando el rechazo agudo o crónico pueden sobreponerse a una patología ya existente o presentarse de manera simultánea y contribuir a la disfunción tardía del injerto, por lo que el análisis de la biopsia puede ayudar a determinar el componente principal de la lesión. Es indispensable la correlación clínico patológica, teniendo en cuenta la enfermedad original, el tipo de inmunosupresión, las pruebas de función hepática, las serologías virales, los autoanticuerpos y los hallazgos radiológicos. En este artículo comentaré las patologías más frecuentes y las que causan más problemas en su diagnóstico durante el período postrasplante tardío

One year survival rates of liver transplant patients exceed 90% while five year survival rates exceed 75%. Understanding the causes of graft losses and patient deaths is essential for further improvement of long-term results. Evaluation of liver biopsies has an important role in explaining liver graft dysfunction that occurs more than one year after transplantation, and thus is key for post-transplant patient management. The interpretation of these biopsies can be very difficult especially because of the high incidence of recurrent diseases that sometimes have clinical and histopathological features that resemble various other conditions. This is especially true for acute and chronic rejection which can overwhelm an existing condition and which can develop simultaneously with other conditions that contribute to late graft dysfunction. Analysis of the biopsy can help determine the main component of a lesion. Clinical findings must be correlated to pathological findings, and the correlation must take into account the original disease, the type of immunosuppression, liver function tests, viral serology, autoantibodies and radiological findings. In this article I will discuss the most common diseases and those that cause the most problems for diagnosis during the late post-transplant period

RESUMO

Introducción: El Síndrome de Reynolds es la asociación de esclerosis sistémica (SSC) con cirrosis biliar primaria (CBP). Descrito en 1934 por Milbradt y Reynolds en 1976 describió seis casos. Caso: Presentamos tres casos de mujeres atendidas en el Servicio de Reumatologìa del Hospital Carlos Andrade Marín, con patología hepática autoinmune y signos de esclerosis sistémica. El diagnóstico fue confirmado mediante biopsia hepática en dos de ellas y la prueba de fibromax en la restante. Discusión: Reconocer el Síndrome de Reynolds permite el diagnóstico temprano de cirrosis biliar primaria en pacientes con esclerosis sistémica y sospechar esta entidad en quienes padecen enfermedad hepática colestásica autoinmune que, muchas veces, coexisten en forma silenciosa. El diagnóstico oportuno permite intervenciones terapéuticas precoces que podrían mejorar el pronóstico de esta asociación.

Introduction: The Reynolds' syndrome is the combination of systemic sclerosis (SSC) and primary biliary cirrhosis (PBC). It was first described in 1934 by Milbradt. Reynolds in 1976 presented six cases in two of them and fibromax-test in another. Case report: We present three cases of three women treated in the Rheumatology department at Carlos Andrade Marin hosppital who had autoinmune liver disease confirmed by biopsy. Discusion: Recognizing Reynolds' Syndrome allow us to make earlier diagnosis. This autoimmune cholestatic liver disease often remains silent, so that their identification is a valuable diagnostic tool leading to therapeutic interventions.

RESUMO

There are many autoimmune diseases associated with primary biliary cholangitis (PBC), known as primary biliary cirrhosis; however, the association between PBC and warm autoimmune hemolytic anemia (wAIHA) has rarely been reported. It is documented that hemolysis is present in over 50% of the patients with chronic liver disease, regardless of the etiologies. Due to the clear and frequent relationship between PBC and many autoimmune diseases, it is reasonable to suppose that wAIHA may be another autoimmune disorder seen in association with PBC. Here we reported a 53-year-old female patient diagnosed with wAIHA associated with PBC.

RESUMO

ABSTRACT In order to draw evidence-based recommendations concerning the management of autoimmune diseases of the liver, the Brazilian Society of Hepatology has sponsored a single-topic meeting in October 18th, 2014 at São Paulo. An organizing committee comprised of seven investigators was previously elected by the Governing Board to organize the scientific agenda as well as to select twenty panelists to make a systematic review of the literature and to present topics related to the diagnosis and treatment of autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis and their overlap syndromes. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript organized in topics, followed by the recommendations of the Brazilian Society of Hepatology.

RESUMO

Some patients with autoimmune liver disease have characteristics of cholestasis, as well as of autoimmune hepatitis. Despite the fact that this is a relatively frequent clinical condition seen in referral centers for liver diseases, there is little evidence as regards the clinical management of these syndromes due to their low prevalence and the lack of standardized definitions and diagnostic criteria. This is relevant, given that published studies report that there is a lower therapeutic response and poorer outcome in patients with overlap syndrome than in those presenting solely with autoimmune hepatitis. Whether overlap syndromes are distinct entities or the presence of 2 concurrent diseases is still a subject of debate. They should be suspected in autoimmune hepatitis patients that present with signs of cholestasis, as it is known that overlap behavior tends to be more aggressive, with higher rates of cirrhosis and the need for liver transplantation. Treatment response is also poorer and should be directed at the predominant component. Standardized definitions are necessary so that these syndromes can be studied in controlled clinical trials.

RESUMO

Primary biliary cirrhosis (PBC) is a chronic progressive autoimmune disease characterized by portal inflammation and immune-mediated destruction of the intrahepatic bile ducts. Primary Sjögren's syndrome is an autoimmune disease characterized by lymphocytic infiltration of exocrine glands, mainly the lachrymal and salivary glands, in the absence of other definitively diagnosed rheumatologic disease. We report a diagnosed case of primary Sjögren's syndrome associated with PBC. A 59-year-old Caucasian woman went to oral evaluation reporting dry mouth, difficulty in eating associated with burning mouth syndrome, dysgeusia and dysphagia. Intraoral examination revealed extensive cervical caries, gingivitis, gingival retraction, angular cheilitis and atrophic tongue. Hyposalivation was detected by salivary flow and Schirmer's test was positive. Antinuclear and antimitochondrial antibodies were both positive. Anti-Ro/SSA and anti-La/SSB antibodies were negative. A minor salivary gland biopsy of the lower lip was performed. Histopathologic analysis revealed lymphocytic infiltrate with destruction of salivary gland architecture in some areas and replacement of glandular tissues by mononuclear cells. Optimal management of PBC associated with Sjögren's syndrome requires a multidisciplinary approach as the key to optimal patient care. Dental practitioners should be able to recognize the clinical features of this associated condition. Appropriate dental care may prevent tooth decay, periodontal disease and oral infections as well as improve the patient's quality of life.

RESUMO

Cualquier enfermedad que lleve a la alteración del flujo biliar o del metabolismo de las sales biliares se traduce en colestasis. Son múltiples las causas que pueden producirla, sea por su localización anatómica intrahepática o extrahepática, agudas o crónicas, con o sin lesión hepatocelular acompañante, o primarias o secundarias, por lo que resultan numerosas las entidades que deben ser consideradas como parte del diagnóstico diferencial de las enfermedades colestásicas y que plantean un gran reto diagnóstico tanto para el clínico, como para el patólogo (1). En el presente estudio se plantea una aproximación diagnóstica basada en patrones histológicos, haciendo énfasis en las enfermedades colestásicas crónicas del adulto, en próximos estudios se tratarán las de la población pediátrica.

Any disease that leads to impaired bile flow or impaired bile salt metabolism results in cholestasis. There are several causes of the disease related to intrahepatic or extrahepatic anatomical locations, to whether the disease is acute or chronic, to whether or not hepatocellular damage occurs, and to whether or not the condition is primary or secondary. The large number of entities that must be considered in the differential diagnosis of cholestatic diseases poses a major diagnostic challenge for both the clinician and the pathologist (1). This article establishes a diagnostic approach based on histologic patterns which emphasizes adult chronic cholestatic diseases. The next article will focus on the pediatric population.

RESUMO

BACKGROUND: Organ-specific autoimmune diseases may appear in patients with systemic lupus erythematosus (SLE). Gastrointestinal symptoms are well documented in SLE and may be similar to those related to autoimmune gastrointestinal diseases. OBJECTIVE: Our aim was to search for gastrointestinal organ-specific autoantibodies in 194 patients with systemic lupus and 103 healthy controls from Southern Brazil. Methods Anti-endomysium antibodies (IgA-EmA), anti-gastric parietal cells (GPC) antibodies, anti-smooth muscle antibodies (ASMA), anti-mitochondrial antibodies (AMA) and anti-LKM-1 (liver-kidney microsomal) were searched for using indirect immunofluorescence in the sera of patients and controls. RESULTS: The total positivity of antibodies in SLE patients was 14.4% (28/194) and differed significantly from healthy individuals (0.97%; p<0.001). IgA-EmA was more common in lupus patients than in controls (11/194; p=0.009), and one of these patients had dermatitis herpetiformis. Clinical association revealed that IgA-EmA was more common in SLE patients with discoid lesions. The frequency of anti-GPC (p=0.10), ASMA (p=0.16) and AMA (p=0.55) did not differ significantly between groups. No patient presented LKM-1 autoantibodies. One patient presenting anti-GPC was diagnosed with atrophic gastritis and pernicious anemia. CONCLUSION: Only IgA-EmA was significantly associated with lupus and with the presence of discoid lesions. Until now, no obvious association with celiac disease has been found.

RESUMO

Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology. A number of questions regarding its etiology are unclear. CD4+CD25+ regulatory T cells (Tregs) play a critical role in self-tolerance and, for unknown reasons, their relative number is reduced in PBC patients. B-cell-activating factor (BAFF) is a key survival factor during B-cell maturation and its concentration is increased in peripheral blood of PBC patients. It has been reported that activated B cells inhibit Treg cell proliferation and there are no BAFF receptors on Tregs. Therefore, we speculated that excessive BAFF may result in Treg reduction via B cells. To prove our hypothesis, we isolated Tregs and B cells from PBC and healthy donors. BAFF and IgM concentrations were then analyzed by ELISA and CD40, CD80, CD86, IL-10, and TGF-β expression in B cells and Tregs were measured by flow cytometry. BAFF up-regulated CD40, CD80, CD86, and IgM expression in B cells. However, BAFF had no direct effect on Treg cell apoptosis and cytokine secretion. Nonetheless, we observed that BAFF-activated B cells could induce Treg cell apoptosis and reduce IL-10 and TGF-β expression. We also showed that BAFF-activated CD4+ T cells had no effect on Treg apoptosis. Furthermore, we verified that bezafibrate, a hypolipidemic drug, can inhibit BAFF-induced Treg cell apoptosis. In conclusion, BAFF promotes Treg cell apoptosis and inhibits cytokine production by activating B cells in PBC patients. The results of this study suggest that inhibition of BAFF activation is a strategy for PBC treatment.

RESUMO

Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are both autoimmune cholestatic liver disease and the association of these two conditions in the same patient is very rare. We report the case of a female patient presenting with a cholestatic liver disease and a panel of autoantibodies specific for PBC, including antibodies to mitochondrial E2-pyruvate dehydrogenase, gp-210 and Sp-100. Beside these findings, the liver biopsy revealed concentric fibrosis of small biliary ducts and the magnetic resonance cholangiography presented no abnormal findings. Diagnosis of small duct PSC/PBC overlapping was done. No description of this association was found in the literature. Clinical and serological features of this unusual finding are discussed.
