Patients with PSC-IBD were more likely to be treated with only 5-ASA, compared with controls (odds ratio [OR], 3.04; 95% CI, 1.44-6.41) and to have IBD in clinical remission (OR, 2.94; 95% CI, 1.78-4.87).
Additional biological testing applied the assay to samples collected from healthy control participants and two groups diagnosed with inflammatory bowel disease (IBD) (one group treated with the anti-inflammatory 5-aminosalicylic acid (5-ASA) and one group untreated), with results showing significant differences in the concentrations of picolinic acid, kynurenine, and xanthurenic acid.
To explore if mucosal and faecal 5-ASA values correlate with disease activity and/or therapeutic effects in patients with inflammatory bowel disease, especially UC.
Groups were formed: 'possible PD' group, including all who received an anti-Parkinson agent; 'possible IBD' group, those treated with mesalazine and/or derivatives (5-aminosalicylic acid (5-ASA)); and 'possible PD and IBD', including those receiving both anti-Parkinson agent and 5-ASA.
Our results reveal a multifaceted and previously unrecognized effect of 5-ASA on the growth and virulence of IBD- and CRC-associated E. coli, in addition to its inhibitory effect on host cell inflammatory responses.
This contrasts a small decrease in immunomodulator and 5-ASA use for CD and relative constancy of other classes including corticosteroids-only use as primary IBD medication from 2007 to 2015.
5-ASA usage is associated with decreased risks of hospitalization and operation for patients with IBD, whereas thiopurine, corticosteroids, and anti-TNF-α agents are associated with increased risks of hospitalization and hepatitis B and TB reactivation.
5-ASA agents were used more commonly in the pediatric IBD population (96.9% vs. 79.9%; p = 0.0034) as compared to adults whereas corticosteroids (87.5% vs. 76.9%; p = 0.28) and infliximab (25% vs. 9.2%; p = 0.054) were used more frequently in the pediatric CD subgroup as compared to adult CD subgroup.
In study 2, we compared the incidence of herpes zoster among patients with IBD treated with only 5-ASA, with thiopurines, with antagonists of tumor necrosis factor (TNF), with a combination of thiopurines and TNF antagonists, and with vedolizumab.
Therefore, zinc ion cross-linked alginate/N-succinyl-chitosan blend MS appeared to be a good candidate for co-delivery of zinc and 5-ASA to colon, and had great potential application in inflammatory bowel diseases (IBD) treatment.
The TB IRs among IBD patients prescribed 5-ASA, corticosteroids, immunomodulators and anti-TNF-α were 143.5, 208.5, 284.6 and 554.1 per 100 000 person-years, respectively.
No medication seemed to affect vascular measurements, though stiffness parameters were significantly higher in patients treated with 5-ASA (11.9 (9.7) vs 18.2 (10.2), P<0.021), suggesting a lack of efficacy of 5-ASA in protecting IBD patients from early atherogenesis.
Mesalazine (5-aminosalicylic acid, 5-ASA), a currently used drug for anti-inflammatory bowel disease, is easily oxidized by HOCl, a strong oxidant generated in gut inflammation, to produce electrophilic quinones.
This study aimed to examine the effects of AZA, MP, and 5-ASA on the growth of IBD-associated bacterial species and to identify bacterial enzymes involved in immunosuppressive drug metabolism.
Thiopurines are increasingly used in the treatment of inflammatory bowel disease (IBD), being the most common immunosuppressive therapy; however, potentially harmful interactions between thiopurines and other drugs (especially 5-aminosalicylic acid, 5-ASA) were described.
