ABSTRACT

OBJECTIVE:To provide reference for constructing and improving the pharmacovigilance signal management sys - tem in China by comparing signal management system among the European Union (EU),the United States (U. S. )and Japan. METHODS:Literature analysis method was used to systematically compare the similarities and differences on definitions ,sources, detection methods and management process of pharmacovigilance signals among EU ,U. S. and Japan. Some suggestions were put forward for pharmacovigilance management in China. RESULTS & CONCLUSIONS :Regulatory authorities of the EU ,U. S. and Japan did not have a uniform definition on signals ;EU drug administration adopted the definition of the eighth working group of Council for International Organizations of Medical Sciences ,FDA adopted its own definition ,while the Japanese regulatory agency had no clear definition. Currently ,post-marketing surveillance still relied mainly on spontaneous reporting systems ;EU,U. S. and Japan had carried out the signal detection based on the spontaneous reporting system ;EU mainly adopted the proportional reporting ratio method ,U. S. mainly adopts the multiple gamma Poisson Shrinker ,and Japan mainly adopted the reporting ratio method. EU had special guidelines for signal management process ,while the U. S. and Japan did not. It is recommended to accelerate the deve- lopment of the legal and regulatory framework on pharmacovigilance in China ,draw up guidelines on pharmacovigilance practices , strengthen the active ADR surveillance and promote the application of data mining techniques in signal detection field ,for accelerat - ing the standardization and internationalization of China ’s pharmacovigilance work.

ABSTRACT

Objective@#To explore the clinicopathological features of anti-mitochondrial antibody (AMA) negative and positive patients with primary biliary cholangitis-autoimmune hepatitis overlap syndrome (PBC-AIH OS).@*Methods@#Seventy-four cases diagnosed as PBC-AIH OS from June 2017 to April 2018 were enrolled in this study. Among them, forty cases were AMA negative (negative group) and thirty-four cases were AMA positive (positive group). The clinical manifestations, serum biochemical indexes, immunological indexes and histological data of the negative group were compared with the positive group. Mann-Whitney U test and theχ 2test were used for statistical analysis.@*Results@#There was no significant difference in sex, age, clinical manifestations and major liver function indexes (ALT, AST, ALP, GGT, TB, DB) between the negative group and positive group (P> 0.05). The level of IgM in the negative group (1.68 ± 0.87) was significantly lower than positive group (3.77 ± 2.88)(P< 0.05). The positive rates of antinuclear antibodies (ANA) and gp-210 antibodies was lower than positive group (P< 0.05). There were no significant differences in the stages of inflammation and fibrosis between the two groups (P> 0.05), and the bile duct injury was more significant in the negative than positive group (P< 0.05).@*Conclusion@#The serum IgM level of AMA-negative PBC-AIH OS is low, and immunological antibody is often negative, which makes bile duct injury apparent in liver histology. A liver biopsy should be carried out as soon as possible for early diagnosis and treatment.
