2.Clinical applications of serum infliximab trough levels and antibodies to infliximab monitoring in ankylosing spondylitis patients treated with infliximab
Chinese Journal of Rheumatology 2020;24(2):116-119
Objective:To investigate the relationship between serum concentration of infliximab (IFX) and its impact on clinical efficacy to ankylosing spondylitis (AS) and explore the situation of antibodies to IFX(ATI).Methods:A total of 38 AS patients treated with IFX from Jan 2017 to Dec 2018 at Hospital were enrolled. Serum IFX-trough levels (TLs) and ATI were detected before the 8th IFX treatment. Ankylosing spondylitis disease activity score (ASDAS) were measured at the first, 6th, 8th IFX treatment. The results were analyzed in relation to the clinical response to treatment. One-way analysis of variance, Kruskal-Wallis test, χ2-test, Logistic regression were used for statistical analysis. Results:① ATI against IFX were detected in6 patients (16%). ② The increase of ASDAS in the 8th IFX treatment compared with the 6th IFX treatment was grouped. Based on the receiver operating characteristic curve (ROC), it was calculated that when IFX-TLs was maintained above 0.635 μg/ml, the patient's condition could be kept stable. ③ Logistic regression analysis showed that IFX-TLs was related to BMI [ OR(95% CI)=1.536(1.023, 2.308), P=0.039] and drug combination [ OR(95% CI)=0.218(0.06, 0.797), P=0.021]. Conclusion:The ATI and IFX-TLs is related to the loss of response to IFX treatment. We suggest that the simultaneous measurement of ATI and IFX-TLs may further help to optimizethe therapy in critical situations.

BACKGROUND:
To compare the efficacy and safety of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab (DA-EPOCH-R) with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Waldeyer's ring diffuse large B-cell lymphoma (WR-DLBCL) at a single institution.
METHODS:
This retrospective study included 115 newly diagnosed patients with WR-DLBCL, of whom 68 patients received R-CHOP, and 47 patients received DA-EPOCH-R as their first-line treatment. The baseline features of the two groups were well balanced using a 1:1 propensity score matching method, and a total of 84 cases were obtained, including respective 42 cases in the R-CHOP and DA-EPOCH-R groups, for further survival and prognosis analysis. The primary objectives included progression-free survival (PFS) and overall survival (OS).
RESULTS:
During a median follow-up of 45 months, there were nine (21.4%) deaths in the R-CHOP group and two (4.8%) in the DA-EPOCH-R group. Kaplan-Meier analysis showed statistically significant improvements in PFS and OS in patients with DA-EPOCH-R compared with those treated with R-CHOP (log-rank test, P = 0.025 and P = 0.035, respectively). The 2-year PFS and OS rates in the DA-EPOCH-R group were 90.1% (95% confidence interval [CI]: 81.4-99.8%) and 95.2% (95% CI: 89.0-100.0%), respectively, and 80.5% (95% CI: 69.3-93.6%) and 90.5% (95% CI: 52.8-99.8%) in the R-CHOP group. Patients without B symptoms and elevated lactate dehydrogenase levels had a higher PFS in the DA-EPOCH-R group, with P values of 0.038 (hazard ratio [HR]: 0.11; 95% CI: 0.01-0.88) and 0.042 (HR: 0.19; 95% CI: 0.04-0.94), respectively. There were no statistically significant differences in clinical responses and treatment-related toxicities between the two groups.
CONCLUSION
Compared with patients received R-CHOP, those treated by DA-EPOCH-R had superior PFS, OS, and controlled toxicity in patients with WR-DLBCL.

To improve overall satisfaction of patients with the hospital and build a harmonious doctor-patient relationship, a survey on satisfaction of patients with ECG examination was conducted in a tertiary A hospital. The analysis was carried out from the aspects of inspection environment, inspection process, inspection experience and overall satisfaction. Logistic regression model was used to analyze the effect of various variables on satisfaction. This paper found that the overall satisfaction rate of patients with ECG examination was 85.18%, lower than that of outpatients. Patients with different characteristics had different satisfaction degree with ECG examination. Patient satisfaction was lower on Mondays and Wednesdays than that on other inspection days, and was lower between 10 a.m. and 14 p.m. The longer the waiting time, the lower satisfaction degree of patients with examination. Based on the results, hospitals should improve the construction of humanistic soft environment to improve the medical environment, scientifically plan the medical treatment process of ECG examination, and further strengthen doctor-patient communication. The ECG room should further promote its management level and strengthen its cultural construction.
