ABSTRACT
Objective:To investigate the effects of biologics on psychological status and quality of life in patients with inflammatory bowel disease (IBD).Methods:A cross-sectional survey was conducted in 42 hospitals in 22 provinces (autonomous regions and municipalities directly under the central government) from September 2021 to May 2022. General clinical information and the use of biologics were obtained from adult patients diagnosed with IBD who voluntarily participated in the study. Psychological status was evaluated using the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), and Inflammatory Bowel Disease Questionnaire (IBDQ) assessment tools. Counts were analyzed via the Chi-square test, and datasets that were not normally distributed were analyzed via nonparametric tests. P<0.05 was considered statistically significant. Results:A total of 2 478 valid questionnaires were collected. The GAD-7 score of the biologics group was significantly lower than that of the non-use group [6 (2, 9) vs. 7 (3, 10), Z=-3.49, P<0.001]. IBDQ scores [183 (158, 204) vs. 178 (152, 198), Z=-4.11, P<0.001], intestinal symptom scores [61 (52, 67) vs. 58 (49, 65), Z=-5.41, P<0.001], systemic symptom scores [28 (24, 32) vs. 27 (23, 31), Z=-2.37, P=0.018], emotional ability scores [69 (58, 77) vs. 67 (56, 75), Z=-3.58, P<0.001] and social ability scores [26 (22, 29) vs. 25 (22, 29), Z=-2.52, P=0.012] in the biologics group were significantly higher than in the non-use group. GAD-7 scores [5 (2, 9) vs. 6 (3, 10), Z=-3.50, P<0.001] and PSQI scores [6 (4, 9) vs. 6 (4, 9), Z=-2.55, P=0.011] were significantly lower in the group using infliximab than in the group not using it. IBDQ scores were significantly higher in patients using vedolizumab than in those not using it [186 (159, 205) vs. 181 (155, 201), Z=-2.32, P=0.021] and were also significantly higher in the group treated with adalimumab than in the group not treated with adalimumab [187 (159, 209) vs. 181 (155, 201), Z=-2.16, P=0.030]. However, ustekinumab had no significant effect on any of the scores. Conclusion:The use of biologics is strongly associated with improvements in anxiety status and quality of life in IBD patients.
ABSTRACT
Objective To investigate the potential effects and mechanism on peroxisome proliferator-activated receptor γ-toll-like receptor 4-tumor necrosis factor-α (PPARγ-TLR4-TNF-α) targeted pathway on hyperglycemia induced myocardium inflammation and oxidative stress. Methods Thirty-two Japanese healthy adult rabbits were randomly divided into four groups with 8 rabbits in each group: normal control group (NC group), diabetes mellitus group (DM group), diabetes mellitus + pioglitazone 4 mg·kg-1·d-1 and 8 mg·kg-1·d-1 groups (DM+PGZ 4 mg and 8 mg groups). DM model was reproduced by alloxan of 150 mg/kg through auricular vein injection. On the same day of successful DM model reproduction, the diabetic rabbits were fed with corresponding dose of pioglitazone in DM+PGZ 4 mg and 8 mg groups, but the rabbits in NC group were not challenged. After 8 weeks of feeding, venous blood of left jugular vein bifurcation and myocardium tissue were harvested respectively for the determination of inflammation and oxidative stress parameters. TNF-α, interleukin-1 (IL-1), adiponectin (ADP), nitric oxide (NO) and total nitric oxide synthase (NOS) levels were determined by enzyme linked immunosorbent assay (ELISA), myeloperoxidase (MPO) activity was determined by colorimetric method, superoxide dismutase (SOD) activity was determined by hydroxylamine method, malondialdehyde (MDA) was determined by thiobarbituric acid colorimetric method, and catalase (CAT) activity was determined by UV spectrophotometry method. In addition, the mRNA expressions of TNF-α and TLR4 were determined by real-time quantitate reverse transcription-polymerase chain reaction (RT-qPCR). Results ① IL-1 and TNF-α in serum and myocardium of model rabbits were significantly increased, ADP was significantly decreased, and the mRNA expressions of TNF-α and TLR4 in myocardium were significantly increased, indicating a significant inflammatory reaction. The inflammatory reaction in pioglitazone intervention groups was significantly reduced, TNF-αand IL-1 levels in serum and myocardium of DM+PGZ 4 mg and 8 mg groups were significantly decreased as compared with those of DM group [serum: TNF-α(ng/L) was 268.33±46.57, 261.34±33.73 vs. 331.40±69.05, myocardium: TNF-α (ng/L) was 144.72±26.90, 139.59±14.59 vs. 177.48±27.40; serum: IL-1 (ng/L) was 24.40±2.56, 23.35±3.13 vs. 30.08±5.44, myocardium: IL-1 (ng/L) was 21.26±2.85, 20.54±2.75 vs. 24.78±3.60, all P < 0.05], and ADP levels were significantly increased [serum (μg/L): 19.64±8.85, 20.54±7.47 vs. 15.45±3.06, myocardium (μg/L): 10.31±2.22, 11.49±3.42 vs. 7.76±1.77, all P < 0.05], and the mRNA expressions of TNF-α and TLR4 in myocardium were significantly decreased (TNF-αmRNA: 0.15±0.05, 0.14±0.06 vs. 0.25±0.09; TLR4 mRNA: 0.57±0.17, 0.40±0.18 vs. 0.75±0.35, all P < 0.05). ②Oxidative stress in serum and myocardium of model rabbits was significantly increased, SOD, NO, and total NOS levels were significantly decreased while the serum CAT and MDA levels were significantly increased without effect on MPO. Compared with the DM group, SOD and NO levels in serum and myocardium were significantly increased in DM+PGZ 4 mg and 8 mg groups [serum: SOD (U/L) was 571.39±40.85, 609.28±54.47 vs. 535.10±37.08, myocardium:SOD (U/mg) was 55.74±8.12, 53.60±9.87 vs. 42.26±12.34; serum: NO (μmol/L) was 2.95±0.51, 2.99±0.43 vs. 2.03±0.78, myocardium: NO (nmol/mg) was 1.95±0.37, 2.11±0.26 vs. 1.56±0.33, all P < 0.05], the serum MDA levels were significantly decreased (μmol/L: 20.11±2.34, 19.70±2.02 vs. 23.07±3.06, both P < 0.05), while no significant effect on CAT. There was no significant difference in parameter of inflammatory and oxidative stress between the two pioglitazone intervention groups. Conclusion 4 mg·kg-1·d-1 pioglitazone could activate PPARγ-TLR4-TNF-α targeted pathway, thus inhibit inflammatory and oxidative stress factors expression, and down-regulate hyperglycemia induced myocardium inflammatory and oxidative stress level, but the effect did not show a dose dependent manner.
