Acute fatty liver of pregnancy associated with severe acute pancreatitis: A case report.

Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

A análise morfométrica para avaliar a taxa de progressão da fibrose hepática na hepatite C crônica após o transplante renal: uma série de casos / Morphometric analysis to evaluate hepatic fibrosis progression rate in chronic hepatites C after kidney transplantation: a case serie study

O verdadeiro papel do transplante renal na progressão da fibrose hepática causada pelo vírus da hepatite C ainda é imprevisível. A avaliação histológica do fígado é a melhor forma para estimar a evolução da fibrose, embora a análise semiquantitativa traz limitações importantes. Objetivo: aplicar um ensaio morfométrico quantitativo sobre a progressão da fibrose hepática em pacientes renais crônicos com hepatite C. Métodos: trinta pacientes foram inicialmente avaliados, mas apenas sete foram incluídos. Eles foram submetidos à primeira biópsia perto da data do transplante e a segunda biópsia, pelo menos, quatro anos mais tarde. A terapia imunossupressora adotada em todos os casos foi a azatioprina e micofenolato. A taxa de progressão da fibrose (FPR) foi calculada antes e após a data da cirurgia de cada paciente, de acordo com a classificação de Metavir pontuação e análise morfométrica. Resultados: a FPR calculada pelo escore Metavir não mostrou diferença estatística entre pré e pós-transplante (p = 0,9). A FPR calculada pela análise morfométrica foi de 0,58 ± 0,78 antes do transplante e 3,0 ± 3,3 após a cirurgia, com significância estatística entre estes valores (p = 0,0026). Conclusão: na amostra avaliada, a progressão da fibrose hepática foi documentada e quantificada apenas pela análise morfométrica, que é uma abordagem promissora para avaliação histológica desses pacientes.

The real role of renal transplantation in hepatic fibrosis progression caused by hepatitis C virus is still unpredictable. Histological evaluation of the liver is the best form to estimate fibrosis evolution, although semiquantitative analysis carries important limitations. Objective: to apply a morphometric quantitative assay on hepatic fibrosis progression in renal recipients with hepatits C. Methods: thirty patients were initially evaluated, but only seven were included. They underwent the first biopsy near the transplantation date and the second biopsy at least 4 years later. The immunosuppressant therapy adopted in all cases was azatioprine and micofenolate. Fibrosis progression rate (FPR) was calculated before and after the surgery date in each patient according to Metavir score and morphometric analysis. Results: the FPR calculated by Metavir score showed no statistical difference between pre- and post-transplantation (p=0.9). The FPR calculated by the morphometric analysis was 0.58 ± 0.78 before transplantation and 3.0 ± 3.3 after the surgery, with statistical signifycance between these values (p=0.0026). Conclusion: in the sample assessed, the progression of hepatic fibrosis was documented and quantified only by the morphometric analysis, which is as a promising approach to histological evaluation of these patients.

Re-treatment of previous non-responders and relapsers to interferon plus ribavirin with peginterferon alfa-2a (40KD), ribavirin ± amantadine in patients with chronic hepatitis C: randomized multicentre clinical trial.

INTRODUCTION: A large number of patients with chronic hepatitis C have not been cured with interferon-based therapy. Therefore, we evaluated the efficacy of amantadine combined with the standard of care(pegylated interferon plus ribavirin) in patients who had not responded to or had relapsed after ≥ 24 weeks of treatment with conventional interferon plus ribavirin. MATERIAL AND METHODS: Patients stratified by previous response (i.e., non-response or relapse) were randomized to 48 weeks of open-label treatment with peginterferon alfa-2a (40KD) 180 µg/week plus ribavirin 1,000/1,200 mg/day plus amantadine 200 mg/day (triple therapy), or the standard of care (peginterferon alfa-2a [40KD] plus ribavirin). RESULTS: The primary outcome was sustained virological response (SVR), defined as undetectable hepatitis C virus RNA in serum (< 50 IU/mL) at end of follow-up (week 72). Among patients with a previous non-response, 12/53 (22.6%; 95% confidence interval [CI] 12.3-36.2%) randomized to triple therapy achieved an SVR compared with 16/52 (30.8%; 95% CI 18.7-45.1%) randomized to the standard of care. Among patients with a previous relapse 22/39 (56.4%; 95% CI 39.6-72.2%) randomized to triple therapy achieved an SVR compared with 23/38 (60.5%; 95% CI 43.4-76.0%) randomized to the standard of care. Undetectable HCV RNA (< 50 IU/mL) at week 12 had a high positive predictive value for SVR. A substantial proportion of non-responders and relapsers to conventional interferon plus ribavirin achieve an SVR when re-treated with peginterferon alfa-2a (40KD) plus ribavirin. CONCLUSION: Amantadine does not enhance SVR rates in previously treated patients with chronic hepatitis C and cannot be recommended in this setting.

Acquired hepatocerebral degeneration and hepatic encephalopathy: correlations and variety of clinical presentations in overt and subclinical liver disease.

Acquired hepatocerebral degeneration (AHD) and hepatolenticular degeneration can have similar clinical presentations, but when a chronic liver disease and atypical motor findings coexist, the distinction between AHD and hepatic encephalopathy (HE) can be even more complicated. We describe three cases of AHD (two having HE) with different neuroimaging findings, distinct hepatic diseases and similar motor presentations, all presenting chronic arterial hypertension and weight loss before the disease manifestations. The diagnosis and physiopathology are commented upon and compared with previous reports. In conclusion, there are many correlations among HE, hepatolenticular degeneration and AHD, but the overlapping of AHD and HE could be more common depending on the clinical knowledge and diagnostic criteria adopted for each condition. Since AHD is not considered a priority that affects the liver transplant list, the prognosis in AHD patients remains poor, and flow interruption in portosystemic shunts must always be taken into account.

A degeneração hepatocerebral adquirida (AHD) e a degeneração hepatolenticular podem ter apresentações clínicas semelhantes, mas quando uma doença hepática crônica e achados motores atípicos coexistem, a distinção entre AHD e encefalopatia hepática (HE) pode ser ainda mais complicada. Descrevemos três casos de AHD (dois tendo HE) com diferentes achados em neuroimagem, doenças hepáticas distintas e apresentações motoras semelhantes, todos com hipertensão arterial e perda de peso antes das manifestações motoras. O diagnóstico e a fisiopatologia são comentados e comparados com relatos prévios. Concluímos que existem muitas correlações entre HE, degeneração hepatolenticular e AHD, mas a sobreposição de HE e AHD pode ser mais comum dependendo do conhecimento clínico e da acurácia dos critérios diagnósticos adotados para cada enfermidade. Como a AHD não é considerada prioridade na lista de transplante hepático, o prognóstico dos pacientes com AHD permanece ruim, e a interrupção do fluxo nos shunts portossistêmicos deve ser sempre considerada.
