RESUMO

BACKGROUND & AIMS: We evaluated the efficacy of herbal combination of curcumin-QingDai (CurQD) in active ulcerative colitis (UC). METHODS: Part I was an open-label trial of CurQD in patients with active UC, defined by a Simple Clinical Colitis Activity Index score of 5 or higher and a Mayo endoscopic subscore of 2 or higher. Part II was a placebo-controlled trial conducted in Israel and Greece, randomizing active UC patients at a 2:1 ratio to enteric-coated CurQD 3 g/d or placebo for 8 weeks. The co-primary outcome was clinical response (reduction in the Simple Clinical Colitis Activity Index of ≥3 points) and an objective response (Mayo endoscopic subscore improvement of ≥1 or a 50% fecal calprotectin reduction). Responding patients continued either maintenance curcumin or placebo alone for an additional 8 weeks. Aryl-hydrocarbon receptor activation was assessed by cytochrome P450 1A1 (CYP1A1) mucosal expression. RESULTS: In part I, 7 of 10 patients responded and 3 of 10 achieved clinical remission. Of 42 patients in part II, the week 8 co-primary outcome was achieved in 43% and 8% of CurQD and placebo patients, respectively (P = .033). Clinical response was observed in 85.7% vs 30.7% (P < .001), clinical remission in 14 of 28 (50%) vs 1 of 13 (8%; P = .01), a 50% calprotectin reduction in 46.4% vs 15.4% (P = .08), and endoscopic improvement in 75% vs 20% (P = .036) in the CurQD and placebo groups, respectively. Adverse events were comparable between groups. By week 16, curcumin-maintained clinical response, clinical remission, and clinical biomarker response rates were 93%, 80%, and 40%, respectively. CurQD uniquely up-regulated mucosal CYP1A1 expression, which was not observed among patients receiving placebo, mesalamine, or biologics. CONCLUSIONS: In this placebo-controlled trial, CurQD was effective for inducing response and remission in active UC patients. The aryl-hydrocarbon receptor pathway may merit further study as a potential UC treatment target. CLINICALTRIALS: gov ID: NCT03720002.

RESUMO

Inflammatory bowel diseases (IBDs) often take a chronic debilitating course. Given the chronicity of IBD, the limitations of the available medications, their potential side effects, and the impact of the disease on patients' quality of life, it is not surprising IBD patients are ranked among the highest users of complementary and alternative medicine (CAM). Since CAM has become very popular in real-life practice of Western Communities, caregivers must gain more knowledge about these therapies, their mechanism of action, benefits, and risks. This article reviews and discusses up-to-date scientific and clinical data regarding the most prevalent herbal CAM therapies.

RESUMO

BACKGROUND & AIMS: The phytochemical compound curcumin was reported to be effective in maintaining remission in patients with ulcerative colitis (UC). We investigated curcumin's efficacy in inducing remission in patients with active mild-to-moderate UC. METHODS: We performed a multicenter randomized, placebo-controlled, double-blind study of 50 mesalamine-treated patients with active mild-to-moderate UC (defined by the Simple Clinical Colitis Activity Index [SCCAI]) who did not respond to an additional 2 weeks of the maximum dose of mesalamine oral and topical therapy. Patients were randomly assigned to groups who were given curcumin capsules (3 g/day, n = 26) or an identical placebo (n = 24) for 1 month, with continued mesalamine. The primary outcome was the rate of clinical remission (SCCAI ≤2) at week 4. Clinical and endoscopic responses were also recorded. RESULTS: In the intention-to-treat analysis, 14 patients (53.8%) receiving curcumin achieved clinical remission at week 4, compared with none of the patients receiving placebo (P = .01; odds ratio [OR], 42; 95% confidence interval [CI], 2.3-760). Clinical response (reduction of ≥3 points in SCCAI) was achieved by 17 patients (65.3%) in the curcumin group vs. 3 patients (12.5%) in the placebo group (P < .001; OR, 13.2; 95% CI, 3.1-56.6). Endoscopic remission (partial Mayo score ≤1) was observed in 8 of the 22 patients evaluated in the curcumin group (38%), compared with none of 16 patients evaluated in the placebo group (P = .043; OR, 20.7; 95% CI, 1.1-393). Adverse events were rare and comparable between the 2 groups. CONCLUSIONS: Addition of curcumin to mesalamine therapy was superior to the combination of placebo and mesalamine in inducing clinical and endoscopic remission in patients with mild-to-moderate active UC, producing no apparent adverse effects. Curcumin may be a safe and promising agent for treatment of UC. Clinicaltrials.gov number: NCT01320436.

RESUMO

Ulcerative Colitis (UC) is a chronic inflammatory disease of colon mucosa, which results from inappropriate inflammatory response. Pharmacological treatments that are used to manage UC are usually targeted to moderate the inflammatory response, however, they are associated with significant adverse effects, which call for finding additional treatment options. Curcumin is a polyphenol that is extracted from turmeric (Curcuma longa). This medicinal plant has been traditionally used in India and in China since ancient times. Recently curcumin has been demonstrated to possess anti-inflammatory, anti-proliferative and antibacterial properties. Based on these reports, our article describes a case report of a patient treated with curcumin in addition to 5-Aminosalicylic acid (5ASA) and presents an integrative approach for the treatment of ulcerative colitis.

RESUMO

BACKGROUND: Curcumin and QingDai (QD, Indigo) have been shown to be effective for treating active ulcerative colitis (UC). AIM: To evaluate the real-world experience with the Curcumin-QingDai (CurQD) herbal combination to induce remission in active UC. METHODS: A retrospec-tive multicentre adult cohort study from five tertiary academic centres (2018-2022). Active UC was defined as a Simple Clinical Colitis Activity Index (SCCAI) ≥ 3. Patients were induced by CurQD. The primary outcome was clinical remission at weeks 8-12, defined as SCCAI ≤2 and a decrease ≥3 points from baseline. Secondary outcomes were clinical response (SCCAI decrease ≥3 points), corticosteroid-free remission, faecal calprotectin (FC) response (reduction ≥50%), FC normalisation (FC ≤100 µg/g for patients with FC ≥300 µg/g at baseline), and safety. All outcomes were analysed for patients who were maintaining stable treatment. RESULTS: Eighty-eight patients were included; 50% were biologics/small molecules experienced, and 36.5% received ≥2 biologics/small molecules. Clinical remission was achieved in 41 (46.5%), and clinical response in 53 (60.2%). Median SCCAI decreased from 7 (IQR:5-9) to 2 (IQR:1-3); p < 0.0001. Of the 26 patients on corticosteroids at baseline, seven achieved corticosteroid-free remission. Among 43 biologics/small molecules experienced patients, clinical remission was achieved in 39.5% and clinical response in 58.1%. FC normalisation and response were achieved in 17/29 and 27/33, respectively. Median FC decreased from 1000 µg/g (IQR:392-2772) at baseline to 75 µg/g (IQR:12-136) at the end of inductions (n = 30 patients with paired samples); p < 0.0001. No overt safety signals emerged. CONCLUSION: In this real-world cohort, CurQD effectively induced clinical and biomarker remission in patients with active UC, including patients who were biologics/small molecules experienced.

RESUMO

Curcumin was shown in placebo-controlled trials to induce remission in mild-moderate ulcerative colitis (UC). QingDai (QD, Indigo), another herbal extract, showed efficacy in two UC trials from Japan, but evidence in the Western population is scant. We report on the use of curcumin-QingDai combination (CurQD) for the treatment of moderate-severe UC. Patient 1 was a 24-year-old male with severe UC refractory to cyclosporine and corticosteroids. He partially responded to infliximab but later lost response to an optimized dose of infliximab in combination with 6-mercaptopurine, presenting with worsening symptoms and severe Mayo 3 mucosal inflammation. Initiation of CurQD 2.5 g/day resulted in rapid cessation of blood per rectum. Complete clinical remission ensued within few weeks. Follow-up endoscopies performed 12 weeks later showed only minimal residual inflammation. Infliximab was later stopped due to reimbursement issues, and the patient was successfully maintained on lower doses of CurQD and 6-mercaptopurine for 31 months. Two flares have responded to a temporary increase in QD component dose. Patient 2 was a 59-year-old female with extensive UC not responding to maximal oral + topical 5-ASA and corticosteroids. Despite severe mucosal ulceration (Mayo 3) found on endoscopy, she refused the recommendation for biologics and opted for a short-term limited trial of CurQD. This was initiated at 2,000 mg/day and induced rapid clinical remission. Lower endoscopies performed after 2 and 5 months on CurQD showed complete mucosal healing, and the patient maintained her clinical remission on low-dose CurQD for 49 months. No adverse events were noted in the 2 patients.
