ADE Risk Signal Mining Related to Belimumab Based on the FARES Database / 中国药房

ABSTRACT

OBJECTIVE：To prov ide referen ce for clinical safe and rational use of belimumab by mining the risk signals of adverse drug event （ADE）. METHODS ：ADE reports related to belimumab were collected from FDA adverse event reporting system（FAERS）from the first quarter of 2015 to the first quarter of 2021. The reporting odds ratio （ROR）method and the Medicines and Healthcare Products Regulatory Agency （MHRA）method were adopted to mine the ADE risk signals related to belimumab，setting the threshold as the number of reports ＞3 and the lower limit of 95％ CI ＞1（ROR method ）and the proportional reporting ratio （PRR）＞2，and χ2 ＞4（MHRA method ）. ADEs were counted and classified by using the preferred system organ class （SOC）and preferred term （PT）of Medical Dictionary for Regulatory Activities （MedDRA）. RESULTS & CONCLUSIONS：A total of 3 529 ADE reports with belimumab as the primary suspicious drug were screened ，in which female patients（90.31％）were much more than male patients （6.15％）；age distribution was concentrated in 18-59 years old （41.80％）. There were 1 234 cases（34.97％）of severe ADE reports ，mainly involving hospital or prolonged hospital stay. Most of the reporters were consumers or other non-medical professionals （81.84％）. North America reported the most （70.39％）and the main reporting country was the United States （2 029 reports）. A total of 180 PTs were mined from 3 529 reports，in addition to PTs associated with primary disease （systemic lupus erythematosus ，pain，arthralgia，pyrexia，weight decreased ，swelling，oropharyngeal pain ， etc.），PTs related to medication error （product dose omission ，inappropriate schedule of product administration ，underdose， product availability issue ，etc.）and PTs related to infection （influenza，urinary tract infection ，infection，sinusitis，etc.）were reported in a large number of cases. Twenty-six SOCs were involved ，the top 10 SOC in ADE reports were all kinds of injuries ， poisoning and surgical complications （2 225 reports），infections and infectious diseases （1 247 reports），general disorders and administration site conditions （1 196 reports），musculoskeletal and connective tissue disorders （1 195 reports），surgical and medical procedures（515 reports），etc. PTs in SOC in the first place （all kinds of injuries ，poisoning and surgical complications ）of ADE reports were all related to medication error ；herpes zoster ，kidney infection and cellulitis in SOC in the second place （infections and infectious diseases ）of ADE reports were not included in the drug instruction of belimumab ；most PTs in SOCs such as various nervous system diseases ，immune system diseases ，mental diseases ，benign，malignant and unknown tumors （including cystic and polypoid）which were taken attention in clinic were not included in the drug instruction of belimumab. It is suggested to avoid medication errors as far as possible in clinical use of belimumab ，and to guard against adverse reactions such as herpes zoster ， kidney infection ，cellulitis and various nervous system diseases ，immune system diseases and mental diseases. In addition ，the patients with malignant tumor or related history should use belizumab carefully.
