          Abstract

          Objective

          To evaluate the usefulness of Anali scores, determined by magnetic resonance imaging, for predicting the prognosis of primary sclerosing cholangitis (PSC) and to analyze interobserver variability, as well as to assess the impact of periportal edema and heterogeneous signal intensity on diffusion-weighted imaging of the liver.

          Materials and Methods

          This was a retrospective cohort study of 29 patients with PSC and baseline magnetic resonance imaging. Anali scores, without gadolinium (0-5 points) and with gadolinium (0-2 points), were calculated by two radiologists. Clinical end-points included liver transplantation, cirrhotic decompensation, and death. We calculated intraclass correlation coefficients (ICCs) for interobserver agreement on the Anali scores, performed Kaplan-Meier survival analysis comparing event-free survival among the score strata, and calculated the areas under receiver operating characteristic curves to determine sensitivity and specificity.

          Results

          Among the patients with a clinical event, the median Anali score was 4 (interquartile range [IQR], 2-5) without gadolinium and 2 (IQR, 1–2) with gadolinium, compared with 1 (IQR, 1.0–2.5) and 1 (IQR, 0.25–1.0), respectively, among those without a clinical event. The ICC was 0.79 (95% confidence interval: 0.57–0.91) for the Anali score with gadolinium and 0.99 (95% confidence interval: 0.98–0.99) for the Anali score without gadolinium. Periportal edema and heterogeneous signal intensity in the liver on diffusion-weighted imaging showed no statistical impact on clinical events ( p = 0.65 and p = 0.5, respectively).

          Conclusion

          Anali scores correlate with clinical events in PSC, with a high level of interobserver agreement.

          Objetivo

          Avaliar a utilidade dos escores Anali determinados por ressonância magnética para prever o prognóstico da colangite esclerosante primária (CEP), analisar a variabilidade interobservador e avaliar o impacto do edema periportal e do sinal heterogêneo do fígado em imagens ponderadas por difusão.

          Materiais e Métodos

          Estudo retrospectivo de coorte de 29 pacientes com CEP e ressonância magnética de base. Os escores Anali sem gadolínio (0 a 5 pontos) e com gadolínio (0 a 2 pontos) foram calculados por dois radiologistas. Os desfechos clínicos incluíram transplante de fígado, descompensação cirrótica ou morte. Foram realizados coeficiente de correlação intraclasse (CCI) para a concordância interobservador com relação ao escore Anali, análise de sobrevivência de Kaplan-Meier comparando o tempo livre de eventos de acordo com o escore, e área sob a curva característica de operação do receptor para sensibilidade e especificidade.

          Resultados

          Nos pacientes com evento clínico, a mediana do escore Anali sem gadolínio foi 4 (intervalo interquartil [IIQ]: 2–5) e com gadolínio foi 2 (IIQ: 1–2), enquanto nos pacientes sem evento clínico o escore sem gadolínio foi 1 (IIQ:1–2,5) e com gadolínio foi 1 (IIQ: 0,25–1). A concordância interobservador com gadolínio foi CCI = 0,79 (intervalo de confiança 95%: 0,57–0,91) e sem gadolínio foi CCI = 0,99 (intervalo de confiança 95%: 0,98-0,99). O edema periportal (p = 0,65) e o sinal heterogêneo do fígado nas imagens ponderadas por difusão (p = 0,5) não apresentaram impacto nos eventos clínicos.

          Conclusão

          Os escores Anali se correlacionam com eventos clínicos na CEP, com alto grau de concordância interobservador.

            Primary sclerosing cholangitis – a comprehensive review

            Primary sclerosing cholangitis (PSC) is a rare disorder characterised by multi-focal bile duct strictures and progressive liver disease. Inflammatory bowel disease is usually present and there is a high risk of cholangiocarcinoma and colorectal cancer. Most patients ultimately require liver transplantation, after which disease recurrence may occur. With limited therapeutic options and a lack of proven surveillance strategies, patients currently have significant unmet needs. In the present seminar, we provide a comprehensive review of the status of the field. We emphasise developments related to patient stratification and disease behaviour, and provide an overview of management options from a practical, patient-centered perspective. We survey advances made in the understanding of PSC pathogenesis and summarise the ongoing efforts to develop an effective therapy based on these insights.
