Autoimmune diseases, cancers, and viral infections pose significant global health threats, characterized by chronic pathology, unregulated cellular proliferation, and rapid transmission, respectively, requiring urgent early warning and treatment strategies. Antibodies, primarily classified into autoantibodies and therapeutic antibodies based on their clinical roles, provide essential information and show considerable value in the precise diagnosis and treatment of these serious diseases. Among the technologies utilized in bioanalysis, electrochemical biosensors, with their unique advantages of rapid response, high sensitivity, miniaturization, cost-effectiveness and user-friendly operation, have been developed as a trending technology for precise diagnostic and therapeutic drug monitoring. This review systematically summarizes the relationships and roles of clinically relevant antibodies in autoimmune diseases, cancers, and viral infections, while detailing the composition, strategies, development, and application trends of relevant electrochemical biosensors. Furthermore, it highlights the remaining challenges and opportunities for the advancement and prospects of electrochemical sensors in the context of clinically relevant antibodies.

Objective:To compare the efficacy and safety of Dienogest(DNG)with other drugs in non-surgi-cal pharmacologic treatment and long-term management of drugs after conservative surgery for endometriosis(EMT).Methods:We searched PubMed,Embase,Medline,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,Wanfang,and Weipu databases from the establishment of the database until December 31,2023 for relevant literature on EMT pharmacotherapy.Meta-analysis was performed using Stata 18.0 software to assess the efficacy of DNG,gonadotropin-releasing hormone agonist(GnRH-a),compound short-acting oral contraceptive(COC)and levonorgestrel intrauterine sustained-release system(LNG-IUS)in reducing the diameter of ovarian endometrioma(OMA),relieving pelvic pain and preventing EMT postoperative recurrence in EMT pa-tients after non-surgical drug treatment and conservative surgery,as well as the adverse reactions of drugs.Re-sults:①During non-surgical medication treatment of EMT,there was no statistically significant difference(P>0.05)between DNG and GnRH-a in reducing OMA diameter and relieving pelvic pain.Compared with COC,DNG was superior to COC in reducing the diameter of OMA(WMD 10.44 mm,P=0.017)and relieving pelvic pain(WMD 12.20 mm,P<0.001).②During long-term medication management after conservative EMT surger-y:there was no statistically significant difference(P>0.05)between DNG,GnRH-a,COC and LNG-IUS in re-ducing postoperative recurrence and controlling pelvic pain significant(P>0.05).③Adverse drug reactions:com-pared with GnRH-a,DNG had a reduced risk of bone loss(bone density WMD2.78 g/cm3,P=0.038),hot fla-shes(OR 0.07,P<0.001),and an increased risk of irregular vaginal bleeding(OR 19.10,P<0.001);com-pared with COC,the risk of weight gain,mood abnormalities,and breast tenderness,nausea and vomiting,and sleep disorders in DNG were reduced(OR<1,P<0.05);compared with LNG-IUS,the risk of abnormalities of mood in DNG was increased(OR 9.87,P=0.033).Conclusions:DNG treatment is more effective than COC in non-surgical drug therapy for EMT.When supplemental medication was given after conservative EMT surgery,DNG,like other drugs,can effectively prevent postoperative recurrence and control pelvic pain.The safety of DNG is superior to GnRH-a and COC,slightly inferior to LNG-IUS.

The dynamic tracking of antibody‒drug conjugates (ADCs) in serum is crucial. However, a versatile bioanalytical platform is lacking due to serious matrix interferences, the heterogeneity and complex biotransformation of ADCs, and the recognition deficiencies of traditional affinity technologies. To overcome this, a multiepitope recognition technology (MERT) was developed by simultaneously immobilizing CDR and non-CDR ligands onto MOF@AuNPs. MERT's excellent specificity, ultrahigh ligand density, and potential synergistic recognition ability enable it to target the different key regions of ADCs to overcome the deficiencies of traditional technologies. The binding capacity of MERT for antibodies is ten to hundred times higher than that of the mono-epitope or Fc-specific affinity technologies. Since MERT can efficiently capture target ADCs from serum, a novel bioanalytical platform based on MERT and RPLC‒QTOF-MS has been developed to monitor the dynamic changes of ADCs in serum, including the fast changes of drug-to-antibody ratio from 3.67 to 0.22, the loss of payloads (maytansinol), and the unexpected hydrolysis of the succinimide ring of the linker, which will contribute to clarify the fate of ADCs and provide a theoretical basis for future design. In summary, the MERT-based versatile platform will open a new avenue for in-depth studies of ADCs in biological fluids.
