Alterações hepáticas em transplantados renais do maior centro de transplante do Brasil / Hepatic alterations in kidney transplant recipients from the largest kidney transplant center in brazil

ABSTRACT Background Kidney transplant is the treatment of choice for patients with end-stage renal disease and is associated with lower mortality when compared to dialysis methods. Brazil is the country with the second largest number of kidney transplants in the world and among these patients it has been observed that liver abnormalities are common. The frequency of liver abnormalities ranges from 20-50% post-transplantation, and have an important impact on the survival and quality of life of these patients. There are scarce data about the frequency, causes and characteristics of these alterations. Objective To determine the prevalence of the different causes of hepatic abnormalities in kidney transplant recipients, to associate the characteristics of these abnormalities with demographic, epidemiological and clinical variables, to compare the characteristics of hepatic alterations between different etiologies, and to evaluate possible changes in diagnosis over two different periods of time. Methods Descriptive, cross-sectional observational, epidemiological study was conducted at the outpatient "Hepato-Rim"clinic of Hospital São Paulo (EPM/UNIFESP), a center providing specialized care for patients with hepatic abnormalities and underlying kidney diseases. Results Five-hundred eighty-one transplant patients were evaluated. The most prevalent etiologies of liver abnormalities were hepatitis C and B, iron overload, nonalcoholic fatty liver disease (NAFLD), and drug-induced liver injury (DILI). The most common cause — hepatitis C — was analyzed in greater detail. Compared to the other causes, this infection was more frequent in older patients, female patients, and patients with a longer time since transplantation and hemodialysis. Analysis of the two periods showed that patients of period 1 (P1 — 1993 to 2005) were older and were more frequently referred because of positive serology; referral due to aminotransferases abnormalities predominated during period 2 (P2 — 2006 to 2018). The predominant diagnoses were hepatitis C and B during P1 and NAFLD and DILI during P2. Conclusion Assessment of the main hepatic alterations in kidney transplant recipients is important because it permits better management of these patients in terms of diagnostic investigation and treatment and contributes to the prevention of complications in this special population.

RESUMO Contexto O transplante renal é o tratamento de escolha para pacientes com doença renal terminal e está associado a menor mortalidade quando comparado aos métodos dialíticos. O Brasil é o país com o segundo maior número de transplantes renais do mundo e, entre esses pacientes, observa-se que as alterações hepáticas são comuns. A frequência das alterações hepáticas varia de 20 a 50% pós-transplante e tem importante impacto na sobrevida e qualidade de vida desses pacientes. Existem poucos dados sobre a frequência, causas e características dessas alterações. Objetivo Determinar a prevalência das diferentes causas de anormalidades hepáticas em receptores de transplante renal, associar as características dessas anormalidades a variáveis demográficas, epidemiológicas e clínicas, comparar as características das alterações hepáticas entre diferentes etiologias e avaliar possíveis alterações no diagnóstico em dois períodos diferentes de tempo. Métodos Estudo epidemiológico descritivo, transversal, observacional, realizado no ambulatório "Hepato-Rim" do Hospital São Paulo (EPM/UNIFESP), centro de atendimento especializado a pacientes com anormalidades hepáticas e doenças renais de base. Resultados Quinhentos e oitenta e um pacientes transplantados foram avaliados. As etiologias mais prevalentes de anormalidades hepáticas foram hepatite C e B, sobrecarga de ferro, doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas. A causa mais comum — hepatite C — foi analisada em maiores detalhes. Em comparação com as outras causas, essa infecção foi a mais frequente em pacientes mais velhos, pacientes do sexo feminino e pacientes com mais tempo de transplante e hemodiálise. A análise dos dois períodos mostrou que os pacientes do período 1 (P1 — 1993 a 2005) eram mais velhos e encaminhados com maior frequência devido à sorologia positiva; encaminhamento devido a anormalidades de aminotransferases predominou durante o período 2 (P2 — 2006 a 2018). Os diagnósticos predominantes foram hepatite C e B durante P1 e doença hepática gordurosa não alcoólica e lesão hepática induzida por drogas durante P2. Conclusão A avaliação das principais alterações hepáticas em receptores de transplante renal é importante, pois permite melhor manejo desses pacientes na investigação diagnóstica e no tratamento e contribui para a prevenção de complicações nesta população especial.

Tratamento da hepatite C em pacientes com doença renal crônica e pós-tranplante renal: eficácia e segurança dos esquemas de antivirais de ação direta contendo sofosbuvir / Hepatitis c treatment of renal transplant and chronic kidney disease patients: efficacy and safety of direct-acting antiviral regimens containing sofosbuvir

ABSTRACT BACKGROUND: Direct-acting antivirals have revolutionized hepatitis C treatment, also for patients with chronic kidney disease (CKD), but some controversy exists regarding the use of sofosbuvir (SOF) in patients with glomerular filtration rate (GFR) <30 mL/min. OBJECTIVE: To evaluate the efficacy and safety of these regimens for hepatitis C treatment of patients with CKD and after renal transplantation, as well as the impact of SOF on renal function in non-dialysis patients. METHODS: All patients with hepatitis C and CKD or renal transplant treated with direct-acting antivirals at a referral center in Brazil between January 2016 and August 2017 were included. Efficacy was evaluated based on viral load (HCV RNA) and a sustained virological response (SVR) consisting of undetectable RNA 12 and/or 24 weeks after the end of treatment (SVR12 and SVR24) was defined as cure. Safety was determined by adverse events and ribavirin, when combined, was administered in escalating doses to all patients with GFR <60 mL/min. The impact of SOF on renal function was determined by the measurement of baseline creatinine during and after the end of treatment and its increase was evaluated using the Acute Kidney Injury Network (AKIN) classification. RESULTS: A total of 241 patients (52.7% females) with a mean age of 60.72±10.47 years were included. The combination of SOF+daclatasvir was the predominant regimen in 75.6% of cases and anemia was present in 28% of patients who used ribavirin (P=0.04). The SVR12 and SVR24 rates were 99.3% and 97.1%, respectively. The treatment was well tolerated and there were no major clinically relevant adverse events, with the most prevalent being asthenia (57.7%), itching (41.1%), headache (40.7%), and irritability (40.2%). Among conservatively treated and renal transplant patients, oscillations of creatinine levels (AKIN I) were observed in 12.5% of cases during treatment and persisted in only 8.5% after the end of treatment. Of these, 2.0% had an initial GFR <30 mL/min and this percentage decreased to 1.1% after SOF use. Only 0.5% and 1.6% of the patients progressed to AKIN II and AKIN III elevation, respectively. CONCLUSION: The direct-acting antivirals were safe and efficacious in CKD patients treated with SOF-containing regimens, with the observation of high SVR rates, good tolerability and few severe adverse events. The combination with ribavirin increased the risk of anemia and the administration of escalating doses seems to be useful in patients with GFR <60 mL/min. In patients with GFR <30 mL/min, SOF had no significant renal impact, with serum creatinine returning to levels close to baseline after treatment.

RESUMO CONTEXTO: Os antivirais de ação direta revolucionaram o tratamento da hepatite C, inclusive para os pacientes com doença renal crônica (DRC), porém ainda há divergências no emprego do sofosbuvir (SOF) quando taxa de filtração glomerular (TFG) <30 mL/min. OBJETIVO: Avaliar a eficácia e segurança desses esquemas no tratamento da hepatite C em pacientes com DRC e pós-transplante renal, além de avaliar o impacto do SOF sobre a função renal dos não-dialíticos. MÉTODOS: Todos os pacientes com hepatite C e DRC ou transplante renal que realizaram tratamento com antivirais de ação direta em centro referenciado do Brasil no período de janeiro/2016 a agosto/2017 foram incluídos. A eficácia foi avaliada por meio da carga viral (HCV-RNA), considerando-se cura uma resposta virológica sustentada (RVS) com resultado indetectável após 12 e/ou 24 semanas do término do tratamento (RVS12 e RVS24). A segurança foi determinada pelos eventos adversos e a ribavirina, quando associada, foi introduzida de forma escalonada em todos os pacientes com TFG <60 mL/min. Para determinação do impacto do SOF sobre a função renal, foram observadas as dosagens de creatinina basal, durante e após término do tratamento com seu incremento avaliado por meio da classificação de AKIN (acute kidney injury network). RESULTADOS: Foram incluídos 241 pacientes, sendo 52,7% do sexo feminino, com média de idade de 60,72±10,47 anos. A associação de SOF+daclatasvir predominou em 75,6% dos casos e anemia esteve presente em 28% dos pacientes que utilizaram ribavirina (P=0,040). As taxas de RVS12 e RVS24 foram de 99,3% e 97,1%. O tratamento foi bem tolerado, com eventos adversos pouco relevantes, sendo os mais prevalentes: astenia (57,7%), prurido (41,1%), cefaleia (40,7%) e irritabilidade (40,2%). Entre os pacientes em tratamento conservador e transplantados renais, os valores de creatinina sofreram oscilações AKIN I em 12,5% dos casos, durante o tratamento, persistindo em apenas 8,5% da amostra após o término, dos quais 2,0% apresentavam TFG <30 mL/min inicialmente, com queda para 1,1% após uso do SOF. Apenas 0,5% e 1,6% evoluíram com elevação AKIN II e AKIN III. CONCLUSÃO: Os antivirais de ação direta foram seguros e eficazes em pacientes com DRC tratados com esquemas contendo SOF, apresentando altas taxas de RVS, boa tolerabilidade e poucos eventos adversos graves. A associação com ribavirina aumentou o risco de anemia, portanto sua introdução de forma escalonada parece ser útil nos pacientes com TFG <60 mL/min. Em pacientes com TFG <30 mL/min o SOF não apresentou impacto renal significativo, com creatinina sérica retornando a valores próximos ao basal após o tratamento.

Hematological and dermatological adverse events during hepatitis C treatment with peg-interferon and ribavirin / Eventos adversos hematológicos e dermatológicos durante o tratamento da hepatite C com interferon peguilado e ribavirina

Objective: To evaluate frequency and impact of adverse events, mainly the hematological and dermatological ones, on sustained virological response, and compliance to hepatitis C treatment. Methods: Patients were treated according to the guidelines of the Brazilian Ministry of Health. Variables associated with hematological and dermatological adverse events were: age, gender, stage of fibrosis, type of Pegylated interferon, dose reductions, temporary discontinuation and early interruption of treatment. Results: Two hundred and twenty two patients were studied (58% females; age 49±11 years). Dose reductions, temporary interruptions, and early discontinuations were observed in 21%, 8% and 9.5% of patients, respectively. The main adverse events were hematological (anemia, neutropenia and thrombocytopenia) and dermatological (pruritus and alopecia). Anemia (Hemoglobin <10g/dL) was associated with female gender (p<0.001), advanced fibrosis (p=0.047) and dose reductions (p<0.001); neutropenia with advanced fibrosis (p=0.003) and temporary discontinuation (p=0.002); thrombocytopenia with advanced fibrosis (p<0.001) and pegylated interferon α2a (p=0.05). Pruritus and alopecia were associated to female gender (p=0.008 and p=0.02) and treatment interruption (p=0.029 and p=0.02).Conclusion: Hematological and dermatological adverse events are frequent in hepatitis C patients treated with pegylated interferon and ribavirin. However, despite frequent dose reductions and interruptions, these adverse events did not affect the sustained virological response.

Objetivo: Avaliar a frequência e o impacto de eventos adversos, principalmente hematológicos e dermatológicos, na resposta virológica sustentada e na aderência ao tratamento para hepatite C. Métodos: Os pacientes foram tratados de acordo com diretriz do Ministério da Saúde. Variáveis associadas com eventos adversos hematológicos e dermatológicos foram: idade, sexo, grau de fibrose, tipo de interferon peguilado, reduções de dose, descontinuação temporária e interrupção precoce do tratamento. Resultados: Foram estudados 232 pacientes (58% mulheres; idade 49±11 anos). Reduções de dose, interrupções temporárias e descontinuações precoces foram observadas em 21%, 8% e 9,5% dos pacientes, respectivamente. Os principais eventos adversos foram hematológicos (anemia, neutropenia e plaquetopenia) e dermatológicos (prurido e alopecia). Anemia (hemoglobina <10g/dL) se associou a sexo feminino (p<0,001), fibrose avançada (p=0,047) e reduções de doses (p<0,001); neutropenia com fibrose avançada (p=0,003) e interrupção temporária (p=0,002); plaquetopenia com fibrose avançada (p<0,001) e interferon peguilado α2a (p=0,05). Prurido e alopecia se associaram ao sexo feminino (p=0,008 e p=0,02) e interrupção do tratamento (p=0,029 e p=0,02). Conclusão: Eventos adversos hematológicos e dermatológicos foram frequentes em pacientes tratados com interferon peguilado e ribavirina. Entretanto, a despeito de frequentes reduções de dose e interrupções, estes eventos adversos não afetaram a resposta virológica sustentada.

Reativação de leishmaniose durante tratamento de hepatite b crônica com alfainterferona 2b / Leishmaniasis reactivation during treatment of chronic hepatitis B with interferon alpha 2b - case report

Descreve-se aqui um caso de reativação de leishmaniose cutaneomucosa durante o tratamento com alfainterferona 2b (IFN) para hepatite B crônica (HBV). Relato do caso: Paciente masculino, 52 anos, natural da Bahia, procedente de São Paulo onde vivia há 30 anos, encaminhado por HBV. Na história epidemiológica, referiu-se a uma viagem há cinco anos para Porto Seguro-BA, sem apresentar outros fatores de risco. No exame físico para admissão, não havia evidências de doença hepática crônica. Sorologias pré-tratamento: HBsAg e HBeAg positivos, biópsia A0F0 (Metavir). Foi submetido a tratamento com IFN 5 milhões de UI/dia por 24 semanas. No final, apresentava-se HBV DNA detectável, sem soroconversão de HBeAg, porém evoluiu no quarto mês de tratamento com perda ponderal de 10 kg, astenia, sinais e sintomas de sinusite sem melhora clínica após antibioticoterapia. Foi encaminhado para a otorrinolaringologia com rouquidão persistente, destruição de septo nasal, com áreas de crostas, necrose local, alargamento nasal e lesão em palato mole, cuja biópsia mostrou processo inflamatório granulomatoso com necrose caseosa, sugestivo de leishmaniose. Sorologia para leishmaniose IgG 1/80 (IFI) e intradermorreação de Montenegro de 30 mm. Indicado antimoniato de meglumina IV por 30 dias, obteve melhora da rouquidão e das lesões de palato. Conclusão: O quadro clínico sugere reativação da leishmaniose induzida pelo IFN. Acredita-se que este seja o primeiro relato na literatura de reativação de leishmaniose muco-cutânea por uso de IFN, semelhantemente ao que ocorre com a tuberculose. Screening para leishmaniose deve ser realizado em paciente de região endêmica no pré-tratamento com IFN diante da possibilidade de reativação de infecção latente

Clinical and epidemiological profile of female blood donors with positive serology for viral hepatitis B

ABSTRACTINTRODUCTION:Since women are frequently the minority among blood donors worldwide, studies evaluating this population usually reflect male features. We assessed the features of female blood donors with positive serology for HBV and compared them with those of men.METHODS The study comprised consecutive blood donors referred to a specialized liver disease center to be evaluated due to HBsAg- and/or anti-HBc-positive tests.RESULTS: The study encompassed 1,273 individuals, 219 (17.2%) of whom were referred due to positive HBsAg test and 1,054 (82.8%) due to reactive anti-HBc test. Subjects' mean age was 36.8±10.9 years, and 28.7% were women. Female blood donors referred for positive HBsAg screening tests demonstrated higher prevalence of healthcare workers (9.3% vs 2.5%) and lower prevalence of sexual risk behaviors (15.1% vs 41.1%) and alcohol abuse (1.9% vs 19.8%) compared to men. Women had lower ALT (0.6 vs 0.8×ULN), AST (0.6 vs 0.8×ULN), direct bilirubin (0.2 vs 0.3mg/dL), and alkaline phosphatase (0.5 vs 0.6×ULN) levels and higher platelet count (223,380±50,293 vs 195,020±53,060/mm3). Women also had a higher prevalence of false-positive results (29.6% vs 17.0%). No differences were observed with respect to liver biopsies. Female blood donors referenced for reactive anti-HBc screening tests presented similar clinical, epidemiological, and biochemical characteristics to those reported for positive HBsAg screening tests and similarly had a higher prevalence of false-reactive results.CONCLUSIONS: Compared to men, female blood donors with positive HBsAg and/or anti-HBc screening tests demonstrated higher prevalence of professional risk and false-positive results and reduced alteration of liver chemistry.

Acute exacerbation of chronic hepatitis B virus infection in renal transplant patients

Introduction: There is scarce information regarding clinical evolution of HBV infection in renal transplant patients. Aims: To evaluate the prevalence of acute exacerbation in HBV-infected renal transplant patients and its association with the time after transplantation, presence of viral replication, clinical evolution, and use of antiviral prophylaxis. Materials and methods: HBV infected renal transplant patients who underwent regular follow-up visits at 6-month intervals were included in the study. The criteria adopted to characterize exacerbation were: ALT >5 × ULN and/or >3 × baseline level. Predictive factors of exacerbation evaluated were age, gender, time on dialysis, type of donor, post-transplant time, ALT, HBeAg, HBV-DNA, HCV-RNA, immunosuppressive therapy, and use of antiviral prophylaxis. Results: 140 HBV-infected renal transplant patients were included (71% males; age 46 ±10 years; post-renal transplant time 8 ±5 years). During follow-up, 25% (35/140) of the patients presented exacerbation within 3.4 ±3 years after renal transplant. Viral replication was observed in all patients with exacerbation. Clinical and/or laboratory signs of hepatic insufficiency were present in 17% (6/35) of the patients. Three patients died as a consequence of liver failure. In univariate analysis variables associated with exacerbation were less frequent use of prophylactic/preemptive lamivudine and of mycophenolate mofetil. Lamivudine use was the only variable independently associated with exacerbation, with a protective effect. Conclusions: Acute exacerbation was a frequent and severe event in HBV-infected renal transplant patients. Prophylactic/preemptive therapy with antiviral drugs should be indicated for all HBsAg-positive renal transplant patients. .

Do differences exist between chronic hepatitis C genotypes 2 and 3?

Introduction Six genotypes of the hepatitis C virus (HCV) have been identified thus far, and their distribution is well defined. Genotype 1, which is the most prevalent worldwide, is always compared to genotypes 2 and 3, particularly in terms of treatment response. However, little is known about the differences between genotypes 2 and 3 because these genotypes are analyzed together in most studies. Therefore, the aim of this study was to evaluate differences in the clinical, epidemiological, laboratory, and histological parameters between HCV-2 and HCV-3. Methods Patients with chronic hepatitis C infected with genotypes 2 and 3 were studied retrospectively and compared according to clinical, laboratory, and histological aspects. Hepatitis C virus-ribonucleic acid (HCV-RNA) was analyzed quantitatively by TaqMan® real-time PCR, and the HCV genotype was determined by sequencing the 5′-untranslated region. Results A total of 306 patients with chronic HCV-2 (n=50) and HCV-3 (n = 256) were studied. Subtype 2b (n=17/50) and subtype 3a (n=244/256) were the most prevalent among patients infected with HCV-2 and HCV-3, respectively. The mean age was 47 ± 10 years, and there was a predominance of men in the group studied (61%). Comparative analysis between HCV-2 and HCV-3 showed a younger age (p=0.002), less prevalence of arterial hypertension (p=0.03), higher serum albumin levels (p=0.01), more advanced stage of liver fibrosis (p=0.03), and higher frequency of steatosis in patients with HCV-3 (p=0.001). After multivariate regression analysis, all the variables, except serum albumin, remained as variables associated with HCV-3 in the final model. Conclusions Clinical and histological differences exist between HCV-2 and HVC-3, which suggests the need for separate analyses of these genotypes. .

Clinical characteristics associated with hepatic steatosis on ultrasonography in patients with elevated alanine aminotransferase / Características clínicas associadas a esteatose hepática à ultrassonografia em pacientes com alanina aminotransferase elevada

CONTEXT AND OBJECTIVE: The main causes of hepatic steatosis (HS) are alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD). Although liver biopsy is the gold standard for NAFLD diagnosis, the finding of abnormal aminotransferases in abstinent individuals, without known liver disease, suggests the diagnosis of NAFLD in 80-90 percent of the cases. Identification of clinical factors associated with HS on abdominal ultrasound may enable diagnoses of fatty liver non-invasively and cost-effectively. The aim here was to identify clinical variables associated with HS in individuals with elevated alanine aminotransferase (ALT) levels. DESIGN AND SETTING: Cross-sectional study in a single tertiary care center. METHODS: Individuals with elevated ALT, serologically negative for hepatitis B and C, were evaluated by reviewing medical files. Patients who did not undergo abdominal ultrasonography were excluded. RESULTS: Among 94 individuals included, 40 percent presented HS on ultrasonography. Compared with individuals without HS, those with fatty liver were older (P = 0.043), with higher body mass index (BMI) (P = 0.003), diabetes prevalence (P = 0.024), fasting glucose levels (P = 0.001) and triglycerides (P = 0.003). Multivariate analysis showed that BMI (odds ratio, OR = 1.186; 95 percent confidence interval, CI: 1.049-1.341; P = 0.006) and diabetes mellitus (OR = 12.721; 95 percent CI: 1.380-117.247; P = 0.025) were independently associated with HS. CONCLUSIONS: Simple clinical findings such as history of diabetes and high BMI may predict the presence of HS on ultrasonography in individuals with elevated ALT and negative serological tests for hepatitis.

CONTEXTO E OBJETIVO: Doença hepática alcoólica e doença hepática esteatótica não alcoólica (DHENA) são as principais causas de esteatose hepática (EH). Apesar de a biópsia hepática ser o método de escolha para diagnóstico DHENA, o achado de aminotransferases elevadas em indivíduos abstêmios, sem doença hepática conhecida, sugere o diagnóstico de DHENA em 80-90 por cento dos casos. A identificação de variáveis clínicas associadas à EH na ultrassonografia abdominal pode permitir o diagnóstico de DHENA de forma não invasiva e custo-efetiva. O objetivo foi identificar variáveis clínicas associadas à EH em indivíduos com níveis elevados de alanina aminotransferase (ALT). TIPO DE ESTUDO E LOCAL: Estudo transversal em um único centro de atendimento terciário. MÉTODOS: Indivíduos com ALT elevada e sorologias negativas para os vírus de hepatite B e C foram avaliados por meio de revisão de prontuários. Os pacientes não submetidos à ultrassonografia foram excluídos. RESULTADOS: Foram incluídos 94 indivíduos, 40 por cento deles com EH à ultrassonografia. Quando comparados aos indivíduos sem EH, aqueles com EH apresentaram maior prevalência de diabetes (P = 0,024), maiores idade (P = 0,043) e índice de massa corpórea (IMC) (P = 0,003), glicemia de jejum mais elevada (P = 0,001) e triglicerídeos mais elevados (P = 0,003). A análise multivariada evidenciou que o IMC (odds ratio, OR = 1,186, 95 por cento intervalo de confiança, IC 1,049-1,341, P = 0,006) e o diabetes mellitus (OR = 12,721, 95 por cento IC 1,380-117,247, P = 0,025) foram associadas independentemente à EH. CONCLUSÕES: Achados clínicos simples como história de diabetes e o IMC elevado podem predizer a presença de EH à ultrassonografia de indivíduos com ALT elevada e sorologias negativas para hepatite.

Cerebral venous thrombosis and hepatitis: case report / Trombose venosa cerebral e hepatite: relato de caso

Among the many infective causes of cerebral venous thrombosis (CVT), viral hepatitis is been regarded as a rare associated condition. We report on a 56-years-old man presenting CVT associated with hepatitis B and C coinfections outlining probable pathogenic mechanisms. We suggest that virus B and C serology should be performed in the cases of cerebral venous thrombosis with unknown etiology.

Dentre as várias causas infecciosas de trombose venosa cerebral (TVC), a hepatite viral tem sido reconhecida como causa rara de TVC. Relatamos sobre um homem de 56 anos com TVC associada a coinfecção pelos vírus B e C da hepatite, ressaltando possíveis mecanismos patogênicos. Sugerimos que sorologia para vírus da hepatite B e C deveria ser solicitado em todos os casos de TVC de origem indeterminada.

Fatal evolution of systemic lupus erythematosus associated with Crohn's disease

Abstract: The authors describe the case of a young Brazilian woman who was treated of ileocolonic Crohn's disease sparing rectum, as confirmed by colonoscopy and histopathological examination. After a 4-years course of sulfasalazine treatment, she presented with skin facial lesions in vespertilio, fever, arthralgias and high titers of anti-ANA and LE cells. A sulfasalazine-induced lupus syndrome was diagnosed, because ofter sulfasalazine withdrawal and a short course of prednisone, the clinical symptoms disappeared and the laboratory tests returned to normal. Mesalazine 3 g/day was started and patient remained well for the next 3 years, when she was again admitted with fever, weakness, arthralgias, diplopy, strabismus and hypoaesthesia in both hands and feet, microhematuria, haematic casts, hypocomplementemia and high titers of autoimmune antibodies. A diagnosis of associated systemic lupus erythematosus was made. Although a pulsotherapy with methylprednisolone was started, no improvement was noticed. A cyclophosphamide trial was tried and again no positive results occurred. The patient envolved to severe clinical manifestation of general vasculitis affecting the central and peripheral nervous system and lungs, havaing a fatal evolution after 2 weeks. Although uncommon, the association of both disease may occur, and the authors call attention to this possibiliti, making a brief review of literature.

Pancreatite aguda / Acute pancreatitis

Pancreatite aguda é uma doença potencialmente fatal, com ampla variaçäo nos aspectos clínicos e na gravidade, abrangendo um aspectro de doença leve e autolimitada a uma rapidamente progressiva com insuficiência de múltiplos órgäos e óbito. Neste artigo, os autores revisam o tema, abordando principalmente os últimos avanços na patogênese no diagnóstico e no tratamento da pancreatite aguda (au)
