OBJECTIVETo evaluate the response rate to vaccination in different treatment groups (nonimmunosuppressants and immunosuppressants).

DATA SOURCESWe completed an online systematic search using PubMed to identify all articles published in English between January 1990 and December 2013 assessing the effect of the response rate to vaccination in different treatment groups (with and without immunomodulators). The following terms were used: "inflammatory bowel disease (IBD)" OR "Crohn's disease" OR "ulcerative colitis" AND ("vaccination" OR "vaccine") AND ("corticosteroids" OR "mercaptopurine" OR "azathioprine" OR "methotrexate [MTX]") AND "immunomodulators."

STUDY SELECTIONThe inclusion criteria of articles were that the studies: (1) Randomized controlled trials which included patients with a diagnosis of IBD (established by standard clinical, radiographic, endoscopic, and histologic criteria); (2) exposed patients received immunomodulators for maintenance (weight-appropriate doses of 6-mercaptopurine/azathioprine or within 3 months of stopping, 15 mg or more MTX per week or within 3 months of stopping; (3) exposed patients received nonimmunomodulators (no therapy, antibiotics only, mesalazine only, biological agent only such as infliximab, adalimumab, certolizumab or natalizumab or within 3 months of stopping one of these agents). The exclusion criteria of articles were that the studies: (1) History of hepatitis B virus (HBV), influenza or streptococcus pneumoniae infection; (2) patients who had previously been vaccinated against HBV, influenza or streptococcus pneumoniae; (3) any medical condition known to cause immunosuppression (e.g. chronic renal failure and human immunodeficiency virus infection); (4) individuals with positive hepatitis markers or liver cirrhosis; (5) patients with a known allergy to eggs or other components of the vaccines and (6) pregnancy.

RESULTSPatients treated with immunomodulators were associated with lower response rates to vaccination.

CONCLUSIONSImmunomodulators may impair the immune response to vaccination in patients with IBD. Vaccination should be made at the time of diagnosis or before starting immunosuppressed therapy.

The occurrence of inflammatory bowel disease (IBD) is related to environmental factors, host immune status, genetic susceptibility and flora imbalance. With the development of sequencing technologies, the relationship between intestinal microbiota and IBD has been further studied and confirmed in many aspects. This article summarizes the characteristics of microbiota alterations in patients with IBD, as well as the role and mechanisms of microbiota dysbiosis in the onset and development of IBD, and discusses the research status of therapies based on intestinal microbiota, prospecting the future of intestinal flora in the prevention, diagnosis, treatment and prognosis of IBD.

The incidence of inflammatory bowel disease in China is rising on a yearly basis, followed by an increased number of patients who require surgery and those who suffer from maneuver postoperative complications. Surgical treatment is important in the management of patients with inflammatory bowel diseases. Management and prevention of postoperative complications is also a key factor to the success of surgical treatment if it is not more important than the surgical procedure itself. In this article, the most recent literatures in this field will be reviewed combined with our own clinical experiences. The types, risk factors, preoperative prevention strategies as well as postoperative management of surgical complications of patients with inflammatory bowel disease will be discussed.

Protein-calorie malnutrition and deficiencies of specific nutrients could commonly occur in various types of gastrointestinal diseases. These nutritional problems could delay recovery from diseases, resulting in increased morbidity and mortality, and impairment of quality of life. Parenteral nutrition (PN) is one of the methods of nutritional support through which macronutrients (glucose, amino acids, and triglycerides), micronutrients (vitamins and trace elements), water, and electrolytes are administered via peripheral or central venous route. PN could play an important role for patients for whom enteral/oral feeding is contraindicated or cannot meet the patients' requirement for adequate nutrition due to anatomical and/or functional problems. Since insufficient and excessive PN supplement could both be harmful for patients, it is very important to adhere to correct indication, optimal timing, and dosage/composition of PN. In this article, the current role of PN for various gastrointestinal diseases will be reviewed and discussed.

Crohn disease (CD) is a chronic inflammatory bowel disease that affects the entire gastrointestinal tract but is most frequently localized to the large and small bowel. Small bowel endoscopy helps with the differential diagnosis of CD in suspected CD patients. Early diagnosis of CD is preferable for suspected CD conditions to improve chronic inflammatory infiltrates, fibrosis. Small bowel endoscopy can help with the early detection of active disease, thus leading to early therapy before the onset of clinical symptoms of established CD. Some patients with CD have mucosal inflammatory changes not in the terminal ileum but in the proximal small bowel. Conventional ileocolonoscopy cannot detect ileal involvement proximal to the terminal ileum. Small bowel endoscopy, however, can be useful for evaluating these small bowel involvements in patients with CD. Small bowel endoscopy by endoscopic balloon dilation (EBD) enables the treatment of small bowel strictures in patients with CD. However, many practical issues still need to be addressed, such as endoscopic findings for early detection of CD, application compared with other imaging modalities, determination of the appropriate interval for endoscopic surveillance of small bowel lesions in patients with CD, and long-term prognosis after EBD.

Nutrition, as a definite environmental factor, has been implicated in the pathogenesis of inflammatory bowel disease (IBD). Although low-fiber, high-sugar, and high-animal fat diets have been proposed as a risk factor, the role of nutrition in IBD still needs more conclusive evidence. Nutritional deficiency is a common problem in IBD patients. The goals of nutritional intervention are the prevention and correction of malnutrition, the prevention of osteoporosis, and the promotion of optimal growth and development in childhood. Enteral nutrition is effective in induction and maintenance of the clinical remission in adults and promoting growth in children with Crohn's disease. The n-3 polyunsaturated fatty acids contained in fish oil may provide short-term benefit to patients with IBD.

BACKGROUND/AIMS: Vaccinations are generally recommended in patients with inflammatory bowel disease (IBD). However, several studies showed low rates of vaccinations in IBD patients. Furthermore, vaccination rate among IBD patients in Korea has never been investigated. We investigated the vaccination rate among IBD patients in Korea and evaluated some factors that might affect the vaccination rate. METHODS: From November 2011 to February 2012, a total of 192 patients with IBD who visited Samsung Medical Center (Seoul, Korea) answered the IRB-approved questionnaire. The questionnaire included their sex, age, residence, past medical history, type of IBD, duration of illness, medications, history of vaccination about measles-mumps-rubella (MMR), varicella, tetanus-diphtheria (Td), influenza, hepatitis A and B, pneumococcus and human papilloma virus (HPV). RESULTS: One hundred twenty one (63.0%) male and 71 (37.0%) female answered the questionnaire. The mean age of the enrolled patients was 39.7 (18-76) years. Eighty four patients (43.8%) had ulcerative colitis and 108 patients (56.3%) had Crohn's disease (CD). The percentage of the patients who had got vaccination was 42.2% for MMR, 34.9% for varicella, 15.6% for Td, 37.5% for influenza, 15.6% for hepatitis A, 52.6% for hepatitis B, 6.3% for pneumococcus and 11.3% for HPV respectively. Not knowing the necessity or the existence were the common reasons for non-vaccination. Age less than 40 years, CD patients and duration of illness less than 10 years were associated with a higher vaccination rate (p=0.002, 0.015 and 0.020, respectively). CONCLUSIONS: Immunization rates for recommended vaccinations were very low in patients with IBD. Efforts to improve vaccination rate are needed.

The risk of developing colorectal cancer is increased in patients with inflammatory bowel disease. Surveillance colonoscopy has not been shown to prolong survival and rates of interval cancer are reported to be high. Continuing colonic inflammation has been shown to be important in the development of colorectal cancer and therefore anti-inflammatory agents such as the 5-aminosalicylates and immunomodulators have been considered as potential chemopreventive agents. This review focuses on various chemopreventive agents that have been clearly shown to reduce the risk of colorectal adenoma and cancer in the patients with inflammatory bowel disease.

Inflammatory bowel disease (IBD) is a long-standing disease that often requires long-term use of immunosuppressive agents including immunomodulators (such as azathioprine, 6-mercaptopurine and methotrexate) and tumor necrosis factor-alpha inhibitors (such as infliximab and adalimumab). Introduction of immunosuppressive therapies, however, involves the risk of host susceptibility to opportunistic infections in this patient population. Therefore, adequate immunization for vaccine-preventable infectious diseases is currently recommended for all patients with IBD and is emerging as an important target for quality improvements in IBD care. However, ongoing issues regarding underuse of immunization, safety and efficacy of vaccines in patients with IBD remain. For quality improvements in IBD care, all physicians should follow the recent immunization guidelines proposed by professional IBD societies. Additionally, there are ongoing needs for intensive educational programs regarding a role of immunization in long-term care of IBD and up-to-date immunization guidelines. Immunization status should be checked at the time of diagnosis of IBD and timely vaccination before initiation of immunosuppressive therapies can be a practical solution for maximizing the efficacy of vaccination at this point. Inactivated vaccines can be used safely irrespective of immunization status of patients, while attenuated vaccines are contraindicated in patients on immunosuppressive therapies. This article reviews an ideal strategy for vaccinating patients with IBD based on the currently recommended immunization guidelines.
