    This article details the diagnosis and treatment process of a middle-aged and elderly male CD patient undergoing chemotherapy after gastric cancer surgery, which finally improved after 5 years of treatment, and once again confirmed that vedelizumab is at the top of
    the safety pyramid of IBD treatment.


    Inflammatory bowel disease (IBD) is a chronic inflammatory bowel disease that primarily affects the digestive system, with Crohn's disease (CD) and ulcerative colitis (UC) being the main types [1].


    At present, the cause of CD is not clear, the symptoms of the lesion can invade the entire digestive tract, patients are mainly manifested as diarrhea, abdominal pain, fistula and perforating inflammation, mostly in segmental, asymmetric distribution, symptoms have the characteristics of repeated attacks and remission, and so far there is no treatment plan to completely cure the disease [2, 3].


    In this issue, Dr.
    Xu Xiaoyan, attending physician of the Department of Gastroenterology of Weihai Municipal Hospital, is invited to share a classic case of CD, and see how a CD patient can defeat nearly 5 years of stubborn Crohn's disease
    through vedelizumab upgrade treatment.

    3 Diagnosis of enteroscopy

    in 2019: After multi-hospital consultation, the final diagnosis was Crohn's disease A3L1B1, CDAI score 5
    .

    Treatment regimen: the patient weighed 71 kg, and 60 mg methylprednisolone sodium succinate was used for × 7 days; Oral methylprednisolone tablets, the first dose of 48 mg, when decreasing by 4 mg to 20 mg per week, and decreasing by 2 mg per week; Oral methylprednisolone tablets were added 1 tablet (qd) after 20 days, and 2 tablets (qd) after half a month; Protective drug Naxin, Diqiao, calcitriol softgel 1 tablet / day
    .
    In mid-February 2020, hormones were discontinued, azathioprine 2 tablets/day were maintained for 1 year, and colonoscopy
    was stopped for 1 week due to discomfort such as azathioprine fatigue.


    Fourth escalation of vedelizumab in 2021


    Present medical history: the patient's abdominal pain, abdominal distension and bowel movements were significantly improved, and after taking hormones in the morning, he felt abdominal discomfort, malaise, and soreness of the lower limbs, and the above symptoms improved
    on their own after about 1 hour.

    Ancillary examination: colonoscopy:
    multiple flaky longitudinal ulcers at the end of the ileum, peripheral mucosal hyperemia and edema, biopsy toughness, no obvious abnormalities in the whole colon (Figure 4).


    Fig.
    4 CDST score of precolonoscopy
    with vedelizumab in 2021 (Fig.
    5):
    the total score was 19.
    56, which predicted that the response rate of patients receiving vedelizumab was high
    .

    Fig.
    5 CDST scoring

    regimen: The patient started a single dose of 300mg of vedelizumab in 2021 for escalation
    .
    Colonoscopy
    is repeated six months after the patient is treated with vedelizumab.

    Colonoscopy: an ulcer scar at the end of the ileum shows that an ulcer is nearly healed and has improved significantly (Fig.
    6).


    Fig.
    6 Summary of colonoscopy case after vedelizumab
    treatment, the patient is a middle-aged and elderly man, with a history of radical gastric cancer resection and 3 courses of chemotherapy after surgery 2 years before the onset of CD, and multiple colonoscopy
    in the past 5 years of treatment showed terminal ileal ulcer, no abnormalities in the colorectum, and slightly improved symptoms after taking mesalazine.
    However, the intestinal ulcer did not improve
    .

    After up to 5 years of treatment, the patient has significantly improved from a large number of ulcers distributed under small enteroscopy to only one ulcer scar and one healing, proving that vedelizumab can help early non-complicated CD patients achieve endoscopic remission, and the use of vedelizumab in postoperative patients with vedelizumab is safer, without serious adverse reactions and toxic side effects, bringing a new dawn to patients
    .



    Expert reviews


    CD is a recurrent chronic non-specific intestinal inflammatory disease, and its onset site can widely involve the entire thickness of the digestive tract, mainly manifested as segmental chronic non-specific intestinal inflammation, and the main etiology and pathogenic mechanism are not clear
    .
    CD is characterized by chronic abdominal pain and diarrhea, and is often similar to the clinical manifestations of intestinal tuberculosis, lymphoma, intestinal Behcet, drug-induced intestinal mucosal injury and other diseases, and is not easy to identify
    .

    After nearly 5 years of treatment, the patient used a variety of drugs including mesalazine, and his symptoms improved slightly, but the intestinal ulcer did not improve
    .
    This dilemma
    was reversed with an escalation of treatment with vedelizumab.
    Not only did the patient's symptoms be significantly improved, but endoscopic healing
    was achieved.

    The use of V-CDST before treatment can provide an important reference
    for clinical decision-making by CD doctors.
    Studies have shown that patients with moderate CD with a moderate/high probability of clinical response predicted by V-CDST have a higher mucosal healing rate and a better prognosis [4].

    In this case, the patient's V-CDST score greater than 19 showed a high response rate, suggesting that the use of vedelizumab may bring additional benefit
    to the patient.

    This case is characterized by postoperative cancer with CD, which has higher requirements
    for drug safety and efficacy.
    Available evidence suggests that vedelizumab is at the top of the safety pyramid for IBD treatments, the "safety pyramid" of inflammatory bowel disease treatments [5,6].

    The GEMINI Long-Term Safety (LTS) study included more than 2000 IBD patients, some of whom received vedecrolizumab for more than 9 years
    .
    The final analysis demonstrated that vedecrolizumab has a good safety profile and tolerability and is suitable for long-term treatment in patients with moderate to severe CD, even at a long follow-up period [7].


    The safety of vedelizumab in the treatment of IBD patients after bowel or parenteral surgery has been confirmed
    by several studies.
    In patients with IBD who have undergone bowel or parenteral surgery, vedelizumab does not increase the risk of postoperative infection or other complications [8,9]; In addition, vedelizumab can effectively prevent recurrence after CD surgery in CD patients, and the recurrence rate of endoscopic CD within one year is significantly lower than that of ustekinumab [10,11].

    Therefore, the safety of vedelizumab in the treatment of gastric cancer postoperative CD in this case has sufficient evidence-based evidence
    .

    In terms of efficacy, vedelizumab has also been shown to have good CD endoscopic healing effect
    .
    VERSIFY, a Phase 3b prospective multicenter, open-label, single-arm study to evaluate the efficacy of vedecrolizumab in clinical and endoscopic remission in the treatment of active CD, showed that 11.
    9% of all patients achieved endoscopic response at week 26 and 17.
    9%
    achieved endoscopic response at week 52.
    Patients with CD who had not previously received antitumor necrosis factor-α (TNF-α) had better outcomes, with complete mucosal healing rates (visible ulcer disappearance) at weeks 26 and 52 of 19.
    6 and 25 percent, respectively [12].

    The real-world study of Victoria in the United States has also confirmed that vedelizumab has a higher rate of clinical remission and mucosal healing in patients with moderate CD [13].


    It can be seen that for the treatment of CD patients after gastric cancer surgery in this case, the use of vedelizumab can balance safety and efficacy
    .
    At the same time, the V-CDST scoring tool used to evaluate it before treatment can predict the patient's response to vedelizumab and better guide clinical treatment
    .

    The current drug treatment methods of CD mainly include traditional drug treatment, biological agents, and traditional Chinese medicine compounds
    .
    In recent years, the study of vedelizumab has stood out [2], which has been shown to induce and maintain CD imaging improvement and healing, hoping to accumulate more clinical evidence to further support
    drug decisions.
