Although the overall prevalence rate is still low, with a population of 1.3 billion, high-risk factors which have contributed to the HIV/AIDS epidemics worldwide continue to prevail in China, including a high rate of injecting drug use and needle sharing, commercial sex with low rates of condom use, and concurrent sex with both commercial sex workers and noncommercial casual or steady sex partners. In addition, there are increasing “double risk” populations overlapping drug users and sex workers, as well as increasing rates of STDs and HIV among high-risk populations. Sexual transmission, therefore, may serve as a bridge connecting high-risk populations with general populations. There is an urgent need to prevent the spread of HIV from these high-risk oooulations into the general oooulation of China.展开更多

After excluding patients with obstructive pancreatitis and biliary pancreatitis and those with a follow-up period of less than 1 year, we conducted a multivariate analysis using the data of 3739 patients to identify the risk factors of CP and subsequently develop a scoring system that could predict the development of CP in patients with AP. In addition, we validated the scoring system using a validation cohort.RESULTS Among the study subjects, 142 patients （12.98%） developed CP among patients with RAP. On the other hand, only 32 patients （1.21%） developed CP among patients with only one episode of AP. The multivariate analysis revealed that the presence of recurrent AP （RAP）, alcoho-lism, smoking habit, and age of onset of 〈 55 years were the four important risk factors for CP. We developed a scoring system （risk score 1 and risk score 2） from the derivation cohort by classifying the patients into low-risk, moderate-risk, and high-risk categories based on similar magnitudes of hazard and validated the performance using another validation cohort. Using the prediction score model, the area under the curve （AUC） [95% confdence interval （CI）] in predicting the 5-year CP incidence in risk score 1 （without the number of AP episodes） was 0.83 （0.79, 0.87）, whereas the AUC （95%CI） in risk score 2 （including the number of AP episodes） was 0.84 （0.80, 0.88）. This result demonstrated that the risk score 2 has somewhat better prediction performance than risk score 1. However, both of them had similar performance between the derivation and validation cohorts.CONCLUSIONIn the study,we identifed the risk factors of CP and devel-oped a prediction score model for CP.展开更多
