Antibiotics as an Adjuvant in Patients With Acute Severe Ulcerative Colitis

Study Purpose

The study is planned as a randomised control trial to study the adjuvant use of antibiotics (ceftriaxone and metronidazole) to achieve a clinical response in hospitalised patients with acute severe ulcerative colitis

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

All patients with active ulcerative colitis who present to the Outpatient department or the emergency services of PGIMER shall be screened. Those patients who have acute severe ulcerative colitis shall be assessed for inclusion into the study. Patients who fulfil the eligibility criteria will be randomised into two groups. Group A will include patients in the intervention arm. They will be given intravenous antibiotics for three days. Injection ceftriaxone 1 gm will be prepared by reconstitution of the crystallized powder form in 100 ml of normal saline. This preparation will then be infused slowly over thirty minutes, after intradermal testing for hypersensitivity. Inj ceftriaxone 1gm IV will be given twelve hourly. Injection metronidazole 500 mg is available from pharmacies in solutions of 100 ml. It will be infused slowly over thirty minutes, three times per day, after intradermal testing for hypersensitivity. Both the drugs will be given for five days. In addition, they will receive the standard of care mentioned below. Group B will include patients from the placebo arm. They will be given the standard of care as mentioned below. In addition, they will be infused 0.9 % saline of similar quantity, colour, and from similarly shaped bottles, for three days after sensitivity testing with the saline. Detailed history and examination shall be done for all the patients. History regarding the stool output, any systemic symptoms, prior treatment history and history regarding any precipitant for the acute episode shall be taken. Examination will include vitals (pulse rate, blood pressure, temperature), general physical examination as well as an abdominal examination. All patients will undergo blood investigations on all three days. This includes a complete blood counts, kidney function tests, serum electrolytes, albumin, C-reactive protein, osteopontin, blood culture. Stool routine microscopic examination, fecal calprotectin, stool assay for clostridium difficile toxin will be done. X ray abdomen will be done on all three days to monitor the diameter of transverse colon. Patients will undergo an unprepared sigmoidoscopy with minimal air insufflation and mucosal biopsy. Biopsies will be taken for histological examination. Procalcitonin, fecal calprotectin and CRP shall be repeated on day 3 of admission. All patients will be prescribed the standard treatment for acute severe colitis, which includes intravenous steroids (Inj Hydrocortisone 100 mg IV QID or Inj Methyprednisolone 60 mg iv OD), anticoagulation, (Inj Unfractionated heparin 5000 IU S/C BD), intravenous fluid supplementation and correction of electrolytes. Patients will be allowed orally and will be prescribed a diet of 25-30 kcal /kg/day.
