RESUMO
INTRODUCTION: Crohn's disease (CD) is a subtype of chronic and incurable inflammatory bowel disease. It can affect the entire gastrointestinal tract and its etiology is unknown. OBJECTIVE: The aim of this consensus was to establish the most relevant aspects related to definitions, diagnosis, follow-up, medical treatment, and surgical treatment of Crohn's disease in Mexico. MATERIAL AND METHODS: Mexican specialists in the areas of gastroenterology and inflammatory bowel disease were summoned. The consensus was divided into five modules, with 69 statements. Applying the Delphi panel method, the pre-meeting questions were sent to the participants, to be edited and weighted. At the face-to-face meeting, all the selected articles were shown, underlining their level of clinical evidence; all the statements were discussed, and a final vote was carried out, determining the percentage of agreement for each statement. RESULTS: The first Mexican consensus on Crohn's disease was produced, in which recommendations for definitions, classifications, diagnostic aspects, follow-up, medical treatment, and surgical treatment were established. CONCLUSIONS: Updated recommendations are provided that focus on definitions, classifications, diagnostic criteria, follow-up, and guidelines for conventional medical treatment, biologic therapy, and small molecule treatment, as well as surgical management.

Ulcerative colitis (US) is a chronic disease of unknown etiology. It is incurable and its clinical course is intermittent, characterized by periods of remission and relapse. The prevalence and incidence of the disease has been increasing worldwide. The update presented herein includes the participation of healthcare professionals, decision-makers, and a representative of the patients, all of whom declared their conflicts of interest. Answerable clinical questions were formulated, and the outcomes were graded. The information search was conducted on the Medline/PubMed, Embase, Epistemonikos, and LILACS databases, and covered grey literature sources, as well. The search was updated on November 30, 2020, with no restrictions regarding date or language. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification system was implemented to establish the strength of the recommendation and quality of evidence. A formal consensus was developed, based on the RAND/UCLA methodology and the document was peer reviewed. The short version of the Clinical Practice Guidelines for the Treatment of Ulcerative Colitis in the Adult Population is presented herein, together with the supporting evidence and respective recommendations. In mild-to-moderate UC, budesonide MMX is an option when treatment with 5-ASA fails, and before using systemic steroids. In moderate-to-severe UC, infliximab, adalimumab, vedolizumab, ustekinumab, and tofacitinib can be used as first-line therapy. If there is anti-TNF therapy failure, ustekinumab and tofacitinib provide the best results. In patients with antibiotic-refractory pouchitis, anti-TNFs are the treatment of choice.

INTRODUCTION: Inflammatory bowel disease (IBD) is a chronic and incurable entity. Therapy with anti-TNF-α agents was the first biologic therapy approved in Mexico for IBD. New biologic agents, such as vedolizumab and ustekinumab, have recently been added, as have small-molecule inhibitors. AIM: To update the biologic therapeutic approach to IBD in Mexico with new anti-TNF-α agents and novel biologics whose mechanisms of action induce and maintain remission of Crohn's disease and ulcerative colitis (UC). MATERIALS AND METHODS: Mexican specialists in the areas of gastroenterology and inflammatory bowel disease were summoned to participate. The consensus was divided into 3 modules, with 49 statements. The Delphi method was applied, sending the statements to all participants to be analyzed and edited, before the face-to-face meeting. During said meeting, the clinical studies were shown, emphasizing the level of clinical evidence, and the final discussion and voting round on the level of agreement of all the statements was conducted. RESULTS: In this second Mexican consensus, recommendations are made for new anti-TNF-α agents, such as golimumab, new biologics with other mechanisms of action, such as vedolizumab and ustekinumab, as well as for the small-molecule inhibitor, tofacitinib. CONCLUSIONS: The updated recommendations focus on patient-reported outcomes, biologic therapy, small-molecule inhibitors, and the safety aspects of each of the drugs.
RESUMO
INTRODUCTION AND AIMS: There is no systematized information for determining/monitoring the burden of inflammatory bowel disease in Mexico. The aim of the present study was to estimate the annual burden of inflammatory bowel disease on the Mexican National Healthcare System, by number of patients seen, hospitalizations, and specific deaths, stratified into age groups. MATERIALS AND METHODS: Utilizing specific databases of the Mexican National Healthcare System registries coded as ICD-10: K50 and K51, we retrieved and analyzed the data corresponding to the patients seen and hospitalized in 2015, stratified by age group, as well as the specific deaths. Treatment trends among physicians were also examined. RESULTS: In 2015, 5,009 women (8.1) and 4,944 men (8.4) with Crohn's disease received medical attention (prevalence of cases seen) and 35.1% of those patients were ≥50years of age. In that same period, 17,177 women (27.7) and 15,883 men (26.9) with ulcerative colitis were seen and 31.6% of those patients were ≥50years of age. The hospitalized cases (prevalence of hospitalized cases) were 1,097 patients (0.91) with Crohn's disease and 43.7% of those patients were ≥50years of age; and 5,345 patients (4.42) with ulcerative colitis and 47.6% of those patients were ≥50years of age. Deaths (specific mortality rate) were: 32 women (0.52) and 36 men (0.50) due to Crohn's disease, and 267 women (4.31) and 186 men (3.15) due to ulcerative colitis. CONCLUSIONS: Inflammatory bowel disease is a burden on the health of Mexican adults and the Mexican National Healthcare System, and it is expected to increase over the next 15years.

Gastric cancer is one of the most frequent neoplasias in the digestive tract and is the result of premalignant lesion progression in the majority of cases. Opportune detection of those lesions is relevant, given that timely treatment offers the possibility of cure. There is no consensus in Mexico on the early detection of gastric cancer, and therefore, the Asociación Mexicana de Gastroenterología brought together a group of experts and produced the "Mexican consensus on the detection and treatment of early gastric cancer" to establish useful recommendations for the medical community. The Delphi methodology was employed, and 38 recommendations related to early gastric cancer were formulated. The consensus defines early gastric cancer as that which at diagnosis is limited to the mucosa and submucosa, irrespective of lymph node metástasis. In Mexico, as in other parts of the world, factors associated with early gastric cancer include Helicobacter pylori infection, a family history of the disease, smoking, and diet. Chromoendoscopy, magnification endoscopy, and equipment-based image-enhanced endoscopy are recommended for making the diagnosis, and accurate histopathologic diagnosis is invaluable for making therapeutic decisions. The endoscopic treatment of early gastric cancer, whether dissection or resection of the mucosa, should be preferred to surgical management, when similar oncologic cure results can be obtained. Endoscopic surveillance should be individualized.

Important advances have been made since the last Mexican consensus on the diagnosis and treatment of Helicobacter pylori (H. pylori) infection was published in 2007. Therefore, the Asociación Mexicana de Gastroenterología summoned 20 experts to produce "The Fourth Mexican Consensus on Helicobacter pylori". From February to June 2017, 4 working groups were organized, a literature review was performed, and 3 voting rounds were carried out, resulting in the formulation of 32 statements for discussion and consensus. From the ensuing recommendations, it was striking that Mexico is a country with an intermediate-to-low risk for gastric cancer, despite having a high prevalence of H. pylori infection. It was also corroborated that peptic ulcer disease, premalignant lesions, and histories of gastric cancer and mucosa-associated lymphoid tissue lymphoma should be considered clear indications for eradication. The relation of H. pylori to dyspeptic symptoms continues to be controversial. Eradication triple therapy with amoxicillin, clarithromycin, and a proton pump inhibitor should no longer be considered first-line treatment, with the following 2 options proposed to take its place: quadruple therapy with bismuth (proton pump inhibitor, bismuth subcitrate, tetracycline, and metronidazole) and quadruple therapy without bismuth (proton pump inhibitor, amoxicillin, clarithromycin, and metronidazole). The need for antimicrobial sensitivity testing when 2 eradication treatments have failed was also established. Finally, the promotion of educational campaigns on the diagnosis and treatment of H. pylori for both primary care physicians and the general population were proposed.

The aim of the Mexican Consensus on Portal Hypertension was to develop documented guidelines to facilitate clinical practice when dealing with key events of the patient presenting with portal hypertension and variceal bleeding. The panel of experts was made up of Mexican gastroenterologists, hepatologists, and endoscopists, all distinguished professionals. The document analyzes themes of interest in the following modules: preprimary and primary prophylaxis, acute variceal hemorrhage, and secondary prophylaxis. The management of variceal bleeding has improved considerably in recent years. Current information indicates that the general management of the cirrhotic patient presenting with variceal bleeding should be carried out by a multidisciplinary team, with such an approach playing a major role in the final outcome. The combination of drug and endoscopic therapies is recommended for initial management; vasoactive drugs should be started as soon as variceal bleeding is suspected and maintained for 5 days. After the patient is stabilized, urgent diagnostic endoscopy should be carried out by a qualified endoscopist, who then performs the corresponding endoscopic variceal treatment. Antibiotic prophylaxis should be regarded as an integral part of treatment, started upon hospital admittance and continued for 5 days. If there is treatment failure, rescue therapies should be carried out immediately, taking into account that interventional radiology therapies are very effective in controlling refractory variceal bleeding. These guidelines have been developed for the purpose of achieving greater clinical efficacy and are based on the best evidence of portal hypertension that is presently available.

INTRODUCTION: Irritable bowel syndrome (IBS) is characterized by recurrent abdominal pain, bloating, and changes in bowel habit. AIMS: To determine the clinical effectiveness of the antispasmodic agents available in Mexico for the treatment of IBS. METHODS: We carried out a systematic review and meta-analysis of randomized controlled clinical trials on antispasmodic agents for IBS treatment. Clinical trials identified from January 1960 to May 2011 were searched for in MEDLINE, the Cochrane Library, and in the ClinicalTrials.gov registry. Treatment response was evaluated by global improvement of symptoms or abdominal pain, abdominal distention/bloating, and frequency of adverse events. The effect of antispasmodics vs placebo was expressed in OR and 95% CI. RESULTS: Twenty-seven studies were identified, 23 of which fulfilled inclusion criteria. The studied agents were pinaverium bromide, mebeverine, otilonium, trimebutine, alverine, hyoscine, alverine/simethicone, pinaverium/simethicone, fenoverine, and dicyclomine. A total of 2585 patients were included in the meta-analysis. Global improvement was 1.55 (CI 95%: 1.33 to 1.83). Otilonium and the alverine/simethicone combination produced significant values in global improvement while the pinaverium/simethicone combination showed improvement in bloating. As for pain, 2394 patients were included with an OR of 1.52 (IC 95%: 1.28 a 1.80), favoring antispasmodics. CONCLUSIONS: Antispasmodics were more effective than placebo in IBS, without any significant adverse events. The addition of simethicone improved the properties of the antispasmodic agents, as seen with the alverine/simethicone and pinaverium/simethicone combinations.

BACKGROUND: Inflammatory Bowel Disease (IBD) compromises two entities: Ulcerative Colitis (UC) and Crohn Disease (CD). The incidence and prevalence vary widely in relation to ethnicity and demographic localization. Historically it has been considered a rare disease in Mexico. OBJECTIVE: To determine the frequency of new UC cases and their clinical characteristics in a referral hospital of North-Eastern Mexico. METHODS: An epidemiological, descriptive and retrospective study was made which included newly diagnosed patients with UC in a five years period. RESULTS: The adjusted rate of patients diagnosed with UC to the number of admissions for year was 2.3, 2.6, 3.0, 3.6 and 4.1/1000 admissions between 2004 and 2008. The rate of newly diagnosed patients with UC has doubled in the year 2008 compared with the year 2004 (p < 0.05). Fifty five percent of the patients showed mild disease, 30% showed moderate disease and 15% showed severe disease. Fifty percent of the patients had pancolitis, left sided colitis was present in 21% and 29% of the patients just had proctitis. Other clinical aspects of UC corresponded to those previously described. CONCLUSION: The frequency of new patients diagnosed with UC has significantly increased in this tertiary-care referral hospital for the last five years.

The purpose of this study was to assess the role of Helicobacter pylori and several genetic polymorphisms in relation to inflammatory bowel disease (IBD). We studied 44 unrelated patients with IBD and 75 subjects with no history of IBD as controls. Using pyrosequencing technology, we identified gene polymorphisms in IL-10, TNF-A, ILB-31, and TLR4. H. pylori status was determined by serology. Individuals homozygous for IL10-592 A or IL10-1082 A genotypes show significantly lower occurrence of IBD (P=0.03 and P<0.01, respectively). Individuals heterozygous at IL10-1082 have significantly increased occurrence of IBD, both ulcerative colitis and Crohn's disease (P<0.01). There was no difference in the prevalence of H. pylori infection between cases and controls. This study provides evidence that variation in IL10 is correlated with IBD occurrence in this Mexican population.

BACKGROUND: In Mexico, there are few reviews of life quality related to health. These reviews do not substitute symptom, analytic and morphologic evaluations by physicians. They only complement them, by introducing the patient;s vision about his perception of his own health. They also intent to reflect the impact of disease on the patient and on his general health. Besides, they also recognize the influence of health on a daily living basis. Objetive: To analyze the nowadays literature existing in Mexico, with regard to the instruments to evaluate the quality of life within patients with gastrointestinal diseases. METHODS: Search of instruments for measuring the status of life related to health in the mexican population in the MEDLINE database, with emphasis on gastrointestinal and hepatobiliar diseases. RESULTS: One hundred references had been found, but only 10 correspond to studies that use different instruments of evaluation of life status related to gastrointestinal diseases in Mexico. Five of these studies are specific questionnaires and five are generic. CONCLUSION: Actually there are few investigations about evaluation of quality of life in Mexican patients, because of the cultural differences within the Hispano-American countries. All of the questionnaires must be evaluated before using them in our population.

BACKGROUND: Crohn's disease and ulcerative colitis are chronic inflammatory disease of the intestine,which frequently require surgery for complications or failure of medical therapy. OBJECTIVE: We seek evidence and provide direction for clinicians about the optimal use of biologic therapy in order to enable steroid free remission in inflammatory bowel disease. METHODS: Scientific literature was reviewed using MEDLINE with a specific focus on biologic medical therapies for inducing and maintaining remission of Crohn disease and ulcerative colitis. RESULTS: Several therapies have demonstrated efficacy for the treatment of active, moderate-to-severe Crohn disease and ulcerative colitis. These include agents which induce remission [infliximab, certolizumaband adalimumab (CD only)] or maintain remission and spare corticosteroids [infliximab,certolizumab and adalimumab (CD only)]. In the patient with UC there is evidence about the efficacy of Infliximab for induce remission in moderate to-severe cases. We present additional information about new drugs in development for the treatment of both diseases. CONCLUSION: There are evidence about the efficacy and safety of biologic therapies that maximize remission and minimize corticosteroid dependence in patients with moderate-to-severe CD and UC.

OBJECTIVE: to assess the efficacy of rabeprazole (RPZ), amoxicillin (Am), and clarithromycin (Cla) (7 vs. 14 days) in the eradication of H. pylori, and to determine the effect of strain-specific antibiotic resistance and host CYP2C19 status. MATERIAL AND METHODS: first, we determined the CYP2C19 status of 100 healthy subjects to establish a sample size for the clinical trial. Then, 59 H. pylori-infected patients were randomized to receive RPZ (20 mg daily) plus Cla (500 mg b.d.) and Am (1,000 mg b.d.) for 7 vs. 14 days. The MIC for Am and Cla were determined using the agar dilution method. The CYP2C19 genotype was determined by the PCR-RFLP method. RESULTS: In the per-protocol analysis (PP) eradication rates were 89.7 and 72% for the 7- and 14-day groups (p = 0.159). In the intention to-treat analysis (ITT) eradication rates were 86.7 and 62.1% in the 7- and 14-day groups, respectively (p = 0.06). None of the strains was resistant to Am, and 4 strains were resistant to Cla: 3 (11.1%) in the 14-day group and 1 (4%) in the 7-day group. Neither strain-specific antibiotic resistance nor host CYP2C19 status influenced eradication rates. CONCLUSIONS: both 7- and 14-day therapies were effective for H. pylori eradication. Strain resistance and CYP2C19 status do not seem to influence eradication rates in the studied population.

The vacA and cagA genotypes of 50 Helicobacter pylori isolates from patients in the north-eastern region of Mexico were characterised by PCR, and the correlation between genotypes and different clinical outcomes was investigated. Strains of H. pylori that are vacA s1/m1 and cagA positive have previously been associated with more severe clinical outcomes, and some studies have shown differences in the vacA and cagA genotypes in different geographical regions. The six possible combinations of the vacA signal (s) and middle (m) regions were identified in this population, and the most frequent genotype was s2/m2. Thirty-two (64%) isolates were identified as cagA-positive. The s region was not amplified from seven of the cagA-positive isolates, and the m region was not amplified from one cagA-negative isolate, indicating that additional subfamilies of s and m genotypes may exist. The s1/m1 genotype was associated with cagA-positive strains (p < 0.05). No association was found between the vacA and cagA genotypes and clinical outcomes.

There are reports of increased antibiotic resistance rates in Helicobacter pylori strains around the world. The aim of this study was to determine the susceptibility patterns in H. pylori strains isolated in Monterrey, Mexico. We studied 62 strains isolated from the same number of symptomatic adult patients. Metronidazole (Mtz), clarithromycin (Cla), amoxicillin (Amx) and tetracycline (Tet) were tested by the E-test method. We observed that 37.1% of the strains were resistant to Mtz (MIC > or = 8 mg/L), and 8.1% to Cla (MIC > or = 8 mg/L), but we did not observe resistance to Amx (MIC > or = 2 mg/L) or Tet (MIC > or = 4 mg/L). In northeastern Mexico, the percentage of resistant strains was similar to that observed in developed countries. These results confirm that it is necessary to evaluate the susceptibility patterns of H. pylori strains by geographic area.
