Description

Technical Field

[0001] The present invention relates to the field of medical information processing technology, and in particular to a hepatitis B surface antigen trajectory pattern prompting method, device, equipment and storage medium. Background Art

[0002] Chronic hepatitis B (CHB) is a major potential factor for the development of cirrhosis and hepatocellular carcinoma (HCC), posing a major threat to global public health. Exploring the risk factors associated with HCC in CHB patients will help develop drugs for CHB. Viral markers play a vital role in the occurrence and development of HCC. Quantitative hepatitis B surface antigen levels are one of the valuable viral markers. Related studies have shown that high levels of HBsAg increase the risk of HCC in treatment-naive individuals with serum HBV DNA <2000IU / mL. However, another study found that in CHB patients with undetectable HBV DNA after nucleoside (acid) analog therapy, HBsAg levels were not associated with the occurrence of HCC. In addition, in untreated CHB patients with hepatitis B E antigen seropositive, persistently high levels of HBsAg were associated with a lower risk of HCC. Therefore, the role of HBsAg in the occurrence and development of HCC remains controversial. More importantly, the relationship between HBsAg trajectory patterns and HCC in CHB patients receiving nucleoside (acid) analog therapy is still unclear.

[0003] Therefore, it is necessary to clarify the correspondence between the HBsAg trajectory pattern and the development of chronic hepatitis B (including development towards cure and development towards liver cancer) to guide the research and development and improvement of chronic hepatitis B.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0054] According to an embodiment of the present invention, a method embodiment of a prompting method for a hepatitis B surface antigen trajectory pattern is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of executable computer instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0055] In this embodiment, a method for prompting a pattern of a hepatitis B surface antigen trajectory is provided, which can be used for medical equipment. Figure 1 is a flow chart of a method for prompting a pattern of a hepatitis B surface antigen trajectory according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0056] Step S101, obtaining hepatitis B surface antigen (HBsAg) information obtained by multiple tests of multiple first objects, where the first objects are chronic hepatitis B objects. If the first objects are converted from a chronic hepatitis B state to other states, only the hepatitis B surface antigen information of the first objects when they are in the chronic hepatitis B state is obtained.

[0057] The first object may be an experimental animal. Other states are states after the development of chronic hepatitis B (including development toward cure and toward liver cancer), including liver cancer state, cure state, liver cirrhosis state, etc. Different states may be further subdivided, for example, the liver cirrhosis state may be subdivided into the early liver cirrhosis state, the late liver cirrhosis state, etc.

[0058] Step S102: obtaining a first grouping result output by a target group base trajectory model, wherein the target group base trajectory model groups the first objects based on the trajectory of the hepatitis B surface antigen information.

[0059] The trajectory of HBsAg information is the dynamic change process of HBsAg. Group-based trajectory modeling (GBTM) can be used to identify objects with similar development trajectories in a group of objects and classify them into specific groups / classes. GBTM can construct multiple groups of trajectory patterns based on the corresponding longitudinal distribution of HBsAg and output grouping probability values.

[0060] Step S103: based on the first grouping result, determine the hepatitis B surface antigen trajectory pattern corresponding to the first object in each group, wherein one group corresponds to one hepatitis B surface antigen trajectory pattern.

[0061] Specifically, the HBsAg trajectory pattern includes at least: a fast decline pattern and a slow decline pattern. Different HBsAg trajectory patterns correspond to different HBsAg decline speeds.

[0062] Step S104: output corresponding first prompt information for the first object in the group, wherein the first prompt information is used to indicate the hepatitis B surface antigen trajectory pattern of the first object, and different hepatitis B surface antigen trajectory patterns correspond to different target states, and the target state is the state after the chronic hepatitis B is converted.

[0063] The pattern prompt method of the hepatitis B surface antigen trajectory provided in this embodiment can output prompt information of the hepatitis B surface antigen trajectory pattern of the first object, and different hepatitis B surface antigen trajectory patterns correspond to different target states. At this time, based on the target state corresponding to the hepatitis B surface antigen trajectory pattern of the first object, the medication of the first object can be adjusted, or the medication of the first object can be determined to be a suitable drug, thereby guiding the development and improvement of the drug.

[0064] In addition, in the embodiment of the present invention, the group-based trajectory model is used to determine the hepatitis B surface antigen trajectory pattern, which does not require the hepatitis B surface antigen information detection time point of the first object to be consistent, nor does it require the hepatitis B surface antigen information detection time interval to be consistent, which greatly increases the convenience of hepatitis B surface antigen data collection.

[0065] In some optional specific implementations, before obtaining the first grouping result output by the target group base trajectory model, the method further includes:

[0066] Establishing a plurality of initial group basis trajectory models, each of the initial group basis trajectory models having a different number of groups;

[0067] Using the initial group basis trajectory model to perform group fitting on the trajectory of the hepatitis B surface antigen information, to obtain a fitting result and an initial grouping result;

[0068] Calculating an evaluation index of the initial group basis trajectory model based on the fitting result and / or the initial grouping result;

[0069] The target group basis trajectory model is selected from the initial group basis trajectory models based on the evaluation index.

[0070] In the embodiment of the present invention, in order to obtain the development trajectory of the object, it is necessary to determine the number of trajectory groups (i.e., groups) and the trajectory morphology. Adhering to the goal of model simplicity and interpretability, multiple initial group-based trajectory models are generally constructed. These group-based trajectory models are grouped into 2-6 groups, and each model fits linear, square and cubic respectively. By comparing the fitting indicators of different models and the professional interpretability of the trajectory group morphology, the most suitable model is selected. The evaluation indicators of the model include but are not limited to the following indicators:

[0071] (1) BIC: Bayesian information criterion. The closer the BIC is to 0, the better the model fit.

[0072] (2) Average posterior probability: The posterior probability indicates the probability that each object belongs to a certain trajectory group. The average posterior probability is the average of the posterior probabilities of all objects in their assigned trajectory groups and is used to evaluate the grouping quality of the model. It reflects the degree of conformity between the members of the class grouped according to the trajectory and the trajectory, and usually >0.7 is an acceptable standard.

[0073] (3) Proportions per class %: generally not less than 5%.

[0074] (4) Odds of Correct Classification measures the ratio of the probability of correctly classifying into each group. It is generally believed that OCC>5 indicates that the model has a high classification accuracy.

[0075] In this embodiment, 2-6 trajectory models were fitted respectively. Among them, the 6-trajectory model had the lowest BIC (BIC = -49216.64), but the proportion of 2 trajectory groups was less than 5%. The 4-trajectory model and the 5-trajectory model also had a proportion of 1 trajectory group less than 5%. The 2-trajectory model and the 3-trajectory model both met the indicators. Combined with the clinical application practicality, model simplicity and interpretability, the 2-trajectory model was finally selected.

[0076] In some specific implementations, the method provided in the above embodiment further includes a process for determining the correspondence between the hepatitis B surface antigen trajectory pattern and the target state, which is specifically as follows:

[0077] Acquire hepatitis B surface antigen information obtained from multiple tests on multiple second objects, where the second objects are chronic hepatitis B objects. If the second object is converted from a chronic hepatitis B state to another state, only acquire the hepatitis B surface antigen information of the second object when it is in the chronic hepatitis B state.

[0078] A second grouping result output by the target group base trajectory model is obtained, where the target group base trajectory model groups the second objects based on the trajectory of the hepatitis B surface antigen information.

[0079] Based on the second grouping results, the hepatitis B surface antigen trajectory pattern corresponding to the second object in each group is determined.

[0080] Obtain state transition information of the first object in each of the groups of the second grouping result;

[0081] If the proportion of the second object's state converted to the target state in the first group is greater than a first preset threshold, the corresponding relationship between the first hepatitis B surface antigen trajectory pattern and the target state is determined, and the first hepatitis B surface antigen trajectory pattern is the hepatitis B surface antigen trajectory pattern corresponding to the first group. The proportion of the second object's state converted to the target state is the ratio of the number of second objects converted to the target state to the number of all second objects in the first group.

[0082] Output second prompt information, where the second prompt information is used to indicate a corresponding relationship between the first hepatitis B surface antigen trajectory pattern and the target state.

[0083] The second object in the embodiment of the present invention may be different from the first object in the above embodiment, or may be partially the same as, or even completely the same as, the first object in the above embodiment. If they are completely the same, the repeated steps may be omitted.

[0084] In the embodiment of the present invention, by constructing a correspondence between the trajectory pattern of hepatitis B surface antigen, a simple and easily available viral marker, and the target state of the object, it is convenient to predict the target state, thereby guiding the direction of drug development.

[0085] In addition, compared with predicting the target state using only the test results of the object at a single time point, the present application uses the hepatitis B surface antigen trajectory to predict the target state with higher accuracy.

[0086] In some specific embodiments, after determining the correspondence between the first hepatitis B surface antigen trajectory pattern and the target state, the method further includes:

[0087] Acquiring hepatitis B surface antigen information obtained from multiple tests of a third subject, wherein the third subject is a subject in a chronic hepatitis B state;

[0088] Acquire the target group base trajectory model, and output a third grouping result after grouping the first object and the third object based on the trajectory of the hepatitis B surface antigen information;

[0089] Based on the third grouping result, determining the group to which the third object belongs;

[0090] Based on the hepatitis B surface antigen trajectory pattern of the first object in the group to which the third object belongs, the hepatitis B surface antigen trajectory pattern corresponding to the third object is determined.

[0091] In an embodiment of the present invention, the third object may be a newly added object, and the hepatitis B surface antigen trajectory patterns of all or most (proportion greater than a threshold) first objects in the group to which the third object belongs are the hepatitis B surface antigen trajectory patterns corresponding to the third object.

[0092] In some specific implementations, after determining the hepatitis B surface antigen trajectory pattern corresponding to the first object in each group based on the first grouping result, the method further includes:

[0093] Acquiring medication information of the first subject in each of the groups;

[0094] If, in the first group, the proportion of the first object's medication information that is the target medication information is greater than a first preset threshold, determining a correspondence between a first hepatitis B surface antigen trajectory pattern and the target medication information, the first hepatitis B surface antigen trajectory pattern being the hepatitis B surface antigen trajectory pattern corresponding to the first group;

[0095] Output third prompt information, where the third prompt information is used to indicate a corresponding relationship between the first hepatitis B surface antigen trajectory pattern and the target medication information.

[0096] In the embodiment of the present invention, appropriate drugs can be screened through the correspondence between the first hepatitis B surface antigen trajectory pattern and the target medication information, thereby facilitating drug development and improvement.

[0097] In some specific implementations, after determining the hepatitis B surface antigen trajectory pattern corresponding to the first object in each group based on the first grouping result, the method further includes:

[0098] Acquire the state transition of the first subject in each of the groups and the baseline information of the first subject, wherein the baseline information includes one or more of age, gender, liver cirrhosis information, hepatitis B E antigen information, and hepatitis B surface antigen information; the baseline information mainly includes information of the first subject before treatment, or information collected for the first time;

[0099] If within the first group, the proportion of the first objects' states converted to the target state is greater than a first preset threshold, obtaining a corresponding relationship between the baseline information and the target state;

[0100] Output fourth prompt information, where the fourth prompt information is used to indicate a corresponding relationship between the baseline information and the target state.

[0101] In the embodiment of the present invention, the first subject is a chronic hepatitis B patient.

[0102] In a specific embodiment, clinical data of 10,175 patients with chronic hepatitis B who received long-term antiviral treatment from the Search-B cohort (NCT02167503) and were followed up from May 2014 to July 2023 can be collected. The 10,175 patients with chronic hepatitis B who received long-term antiviral treatment were excluded according to the following criteria: patients who developed liver cancer before enrollment and within six months of enrollment; patients whose hepatitis B surface antigen had turned negative at enrollment; patients who had received interferon treatment; patients with less than six months of follow-up. After exclusion, 7,929 patients with chronic hepatitis B who received long-term nucleoside (acid) analogue treatment were obtained. In this embodiment, taking liver cancer as the target state as an example, the diagnosis of liver cancer was regarded as the endpoint of the study. The visit time when the patient was first diagnosed with liver cancer was counted as the time of occurrence of the endpoint event. The 7,929 patients with chronic hepatitis B who received long-term nucleoside (acid) analogue treatment were analyzed using the method provided in the embodiment of the present invention, and the results were obtained. Figure 2 Schematic diagram of the fitting curves of the two HBsAg trajectories shown in FIG. Figure 3 The change of the number of patients in the target group base trajectory model group over time is shown in Figure 1. In addition, the following can be obtained: Figure 4 KM survival curves of patients with different trajectory patterns are shown. The fitting statistics of the group-based trajectory model are shown in Table 1. The evaluation indicators of the target group-based trajectory model are shown in Table 2.

[0103] Table 1. Statistics of fitting of the group basis trajectory model

[0104]

[0105] In addition, this embodiment also analyzes the baseline information of the above 7929 chronic hepatitis B patients who received long-term nucleoside (acid) analog therapy, and obtains the group comparison information shown in Table 3 below.

[0106] Table 3 Comparison of baseline information of chronic hepatitis B patients by group

[0107]

[0108] As can be seen from Table 3, compared with the non-liver cancer group, the patients in the liver cancer group were older at baseline, had a higher proportion of males, a higher proportion of liver cirrhosis, a higher proportion of hepatitis B E antigen negatives, a lower hepatitis B surface antigen level, and a shorter duration of antiviral treatment before enrollment.
