ABSTRACT

ObjectiveTo achieve high-dimensional prediction of class imbalanced of adverse drug reaction(ADR) of traditional Chinese medicine(TCM) and to classify and identify risk factors affecting the occurrence of ADR based on the post-marketing safety data of TCM monitored centrally in real world hospitals. MethodThe ensemble clustering resampling combined with regularized Group Lasso regression was used to perform high-dimensional balancing of ADR class-imbalanced data, and then to integrate the balanced datasets to achieve ADR prediction and the risk factor identification by category. ResultA practical example study of the proposed method on a monitoring data of TCM injection performed that the accuracy of the ADR prediction, the prediction sensitivity, the prediction specificity and the area under receiver operating characteristic curve(AUC) were all above 0.8 on the test set. Meanwhile, 40 risk factors affecting the occurrence of ADR were screened out from total 600 high-dimensional variables. And the effect of risk factors on the occurrence of ADR was identified by classification weighting. The important risk factors were classified as follows:past history, medication information, name of combined drugs, disease status, number of combined drugs and personal data. ConclusionIn the real world data of rare ADR with a large amount of clinical variables, this paper realized accurate ADR prediction on high-dimensional and class imbalanced condition, and classified and identified the key risk factors and their clinical significance of categories, so as to provide risk early warning for clinical rational drug use and combined drug use, as well as scientific basis for reevaluation of safety of post-marketing TCM.

ABSTRACT

ObjectiveTo evaluate the clinical safety of Naoxintong (NXT) capsules after marketing, find out the potential risk factors of the drug as soon as possible, and reveal the incidence, nature, and clinical manifestations of the adverse events (ADE) and adverse reactions (ADR) of NXT capsules, so as to provide a basis for safe use of the drug in clinical practice. MethodA prospective, large-sample, multi-center observational cohort study was conducted to monitor all the 7 345 inpatients and outpatients orally taking NXT in 14 hospitals in China from January to December in 2018, with at least one follow-up. The demographic characteristics, disease type, NXT medication, ADR occurrence, characteristics, and prognosis of the patients were collected. SPSS 23.0 was used for single-factor and multivariate logistic regression to predict the influencing factors of ADR. ResultThe male and female patients accounted for similar proportions. There were 5 081 patients (79.40%) aged ≥60 years and 3 153 patients (49.27%) with body mass index (BMI) exceeding the normal standard. There were 344 (5.38%) patients with a history of allergy to medicines and food, 9 (0.14%) patients with a family history of allergy, and 52 (0.81%) patients with a history of allergic diseases. The ADRs associated with NXT occurred in 22 patients, with the incidence of 0.34%. The clinical manifestations of ADR appeared in 31 cases, involving 10 organs/systems, of which gastrointestinal system damage was the most common (17, 54.84%). All ADRs were mild or moderate. Most ADRs (19, 86.36%) occurred within 4 weeks after administration. The patients with alleviated NXT-associated ADRs accounted for 81.82%. No indicators related to significant increases in ADR risks were found. ConclusionNXT is well tolerated in the general population. The hospital centralized monitoring for the clinical safety of oral Chinese patent drugs based on HIS data and Web tracking and follow-up system is an essential means for the post-market research on the safety of drugs.

ABSTRACT

To study the adverse reactions' factors to Danhong injection in the real world. A multi-center, large sample and prospective hospital centralized monitoring method was adopted, and 30 888 cases of Danhong injection from 37 national 3A hospitals were collected to carry out a nested case control design study. These cases were divided into adverse reaction group and non-adverse group. Single factor logistic regression and multiple factor logistic regression were used to analyze data, and investigate the correlation between adverse reaction and gender, allergy history, methods of administration, and combined drug use. One hundred and eight cases of adverse reactions in 30 888 patients were determined, with an incidence of 0.35%. The results showed that Danhong injection combined with other medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol) with history of adverse reactions including scephalosporin allergy and proprietary Chinese medicine allergies had more adverse reactions than the control group(<0.05, estimated coefficient>0), indicating that these six factors were the risk factors for the adverse reaction of Danhong injection. The adverse reaction of Danhong injection combined with the aspirin was less than that in the control group(<0.05, estimated coefficient<0), indicating that the aspirin was a non-risk factor for the adverse reaction of Danhong injection. All the above results indicate that the adverse factors to Danhong injection include scephalosporin allergy, patent Chinese medicine allergy, Danhong injection combined with medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol), suggesting special attention shall be paid in clinical application.

ABSTRACT

OBJECTIVE:To explore the incidence,clinical manifestations and influential factors of ADR induced by Xuebi-jing injection,and to provide reference for safe and rational use of it. METHODS:The inpatients who used Xuebijing injection in our hospital during Jan. 2012 to Dec. 2016 was registered and monitored centrally,and analyzed statistically in respects of clinical characteristics,occurrence time of ADR,clinical manifestation,outcome,etc.RESULTS:A total of 3 300 patients records were in-cluded,involving 81 ADR cases with incidence of 2.45%. There was no correlation between ADR and gender. The incidence of ADR was in high level in the patients with age over 60 years(6.53%),history of allergy(72.84%),original diseases as respirato-ry disease(3.33%),blood system disease(3.11%)and central nervous system disease(3.03%),and receiving combination of TCM injection(34.57%),antibiotics(25.93%)and immune enhancer(14.81%). Single-day culmulative amount with no more than 50 mL had relatively higher proportion(36.67%),and there was no statistical significance in the ADR with different sin-gle-day culmulative amounts(P>0.05). 38.27% of ADR occurred within 30 min after first medication. Organs/systems involved in ADR were mainly skin and its appendants(37.04%),cardiovascular system(19.75%)and gastrointestinal system(14.81%). To-tally 15 cases had severe ADR,which were mainly anaphylactic shock(33.33%,5/15)and systemic rash(20.00%,3/15). All ADR were recovered after drug withdrawal or symptomatic treatment. CONCLUSIONS:ADR induced by Xuebijing injection are mainly anaphylactic type. The incidence of ADR is higher in patients with primary respiratory disease,blood system disease,drug combination,allergic history and advanced age. The part of them are not mentioned in drug package inserts.Manufacturers are sug-gested to collect ADR information and improve drug package insets in time.

ABSTRACT

OBJECTIVE: To investigate the clinical use of ornidazole injection in a wide patient population by the post-marketing hospital centralized monitoring method in order to regulate and guide its rational use, improve the drug specification, and provide a basis for the drug therapy. METHODS: A prospective, multi-center, large sample hospital centralized monitoring method was adopted. Five sentinel hospitals in Hubei Province were selected, and hospitalized patients who received ornidazole injection treatment from July 1, 2015 to October 31, 2015 were observed. The basic information of the patients was recorded, as well as the drug use and adverse events, and then statistical analysis was made. RESULTS: A total of 4396 cases were enrolled in this study, most of them were middle-aged female patients. Ornidazole injection was mainly used before surgeries to prevent infections and after surgeries for treatment of anaerobic infections, abdominal infections and pelvic infections. Irrational drug use existed in clinic, mainly concentrating at unreasonable dosing frequency, excessive dripping speed, and long duration of use. Eleven cases of adverse reactions were collected during the monitoring, indicating an incidence of adverse drug reactions of 2.5‰, and most of the adverse drug reactions occurred within 30 min post drug administration. CONCLUSION: The manufacturers should make further investigation on the dripping speed and quality standard of ornidazole injection to further improve the information in the package insert and regulate the clinical use.
