Background

Chronic inflammatory diseases, including the Inflammatory Bowel Disease (IBD), show an increased risk in the development of atherosclerotic cardiovascular disease and coronary microvascular dysfunction at an early age.

AntiTNF α have proven to be effective in reducing the cardiovascular risk in these malaises, nevertheless due to their mechanism of action, we cannot determine whether such efficacy is due to an adequate inflammation control or due to the specific cytokine blockade, which plays an important role in both the inflammation and the atherogenic process.

Taking this into account, our hypothesis assesses whether using other anti-inflammatory therapies, such as Ustekinumab and Vedolizumab, would achieve a decrease in cardiovascular risk.

Methods

In this observational and retrospective study, we collected cardiovascular risk factors(CVRFs) in 46 patients, immediately before starting Ustekinumab or Vedolizumab and a year after, taking into account if patients were in clinical remission or not.

The CVRFs included were: body mass index (BMI), arterial hypertension, triglycerides values, lipid profile, albumin and C-reactive protein.

Results

46 patients were included, 33(71.74%) with Crohn and 13(28.26%) with Ulcerative Colitis. Of the total number of patients 25(54.35%) were treated with Ustekinumab and 21(45.65%) with Vedolizumab. During the follow-up, only one patient(0.02%) presented a new cardiovascular event.

Paired student's t-test were used for data analysis in both treatment groups, comparing the values ​​of the different CVRFs at the baseline and after one year of treatment. When comparing these values ​​according to clinical remission at one year, no statistically significant differences were observed for any of them.

BMI and weight values were |24.49(DE 4.58) vs 24.93(DE 4.74) p=0,71| and |70.76kg(DE 13.86) vs 71.38kg(DE 13.33) p=0,85| respectively. As for hypertension, no relevant changes were observed, representing 15.22% of the population at the beginning and 17.39% after one year of treatment.

The differences observed in blood glucose values were|86.23(81.87-90.6)mg/dL vs 89.87mg/dL(84.72-95.01) p=0,27|. Regarding the lipid profile, the total cholesterol values were 158.58mg/dL(DE 36.5) and 168.69mg/dL(DE 32.72) p=0.18. HDL at the beginning 44.67mg/dL(DE 11.69) and after one year 47.43mg/dL(DE 10.19) p=0.28 and triglycerides values of 126.65mg/dL(DE 56.38) and 133.5mg/dL(DE 60.95) p=0,61. Albumin levels|4.08g/dL(DE 0.39) vs 4.27g/dL(DE 0.27)|did show significant differences (p=0,01).

Conclusion

Patients treated with Vedolizumab or Ustekinumab do not present a significative reduction in the cardiovascular risk after one year regardless of clinical remission.
