Real-world experience with MMX mesalazine use in Mexican patients with ulcerative colitis at two tertiary care centers.

INTRODUCTION AND AIMS: The 5-aminosalicylates, especially mesalazine, are the first option in the treatment of mild-to-moderate ulcerative colitis (UC). High rates of remission induction and maintenance have been observed with the new multimatrix (MMX) mesalazine formulation, mainly in patients with distal disease. Our aim was to describe the real-world experience with MMX mesalazine in patients with UC at two tertiary care centers. MATERIALS AND METHODS: A retrospective cohort study was conducted that included 142 patients with confirmed UC diagnosis, analyzed in three study groups: 1) oral MMX mesalazine as monotherapy for remission induction, 2) oral MMX mesalazine as monotherapy for remission maintenance, and 3) oral MMX mesalazine plus topical therapy for remission induction. RESULTS: The frequency of clinical remission induction in group 1 was 80.3%, with biochemical remission of 74.2%. Group 2 had 100% clinical and biochemical remission maintenance. The frequency of clinical remission induction in group 3 was 88.6%, biochemical remission was 85.7%, and topical therapy was suspended in 87.3% at the end of follow-up. No adverse events were documented. CONCLUSIONS: There were high percentages of clinical and biochemical remission in the two corresponding study groups and topical therapy was suspended in the majority of patients in ashort follow-up period.

Evaluation of a vaccination regimen and care in relation to follow-up and treatment of patients with inflammatory bowel disease. / Evaluación del esquema de vacunación y cuidados con relación al seguimiento y tratamiento de los pacientes con enfermedad inflamatoria intestinal.

INTRODUCTION AND AIMS: During the clinical course of inflammatory bowel disease, different causes can compromise kidney, liver, and bone marrow function and increase the risk for osteoporosis, infections, and neoplasias. The aim of the present study was to describe the follow-up of Mexican patients with inflammatory bowel disease in relation to their vaccination regimen, treatment-associated risks, and cancer screening. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted within the time frame of February and June 2017. One hundred patients that had a histopathologic diagnosis of inflammatory bowel disease were surveyed about their follow-up vaccination regimen, treatment-associated risks, and cancer screening. SPSS v24 software was employed for the statistical analysis. RESULTS: One hundred patients with inflammatory bowel disease were studied (90% with ulcerative colitis and 10% with Crohn's disease; 60% women, 40% men): 75% stated that they had no vaccination regimen. A total of 71.4% of the women had at least one Pap smear in their lives and 28.6% did not have them done annually. Twenty-four percent of the patients wore sun block daily. A total of 18.2% of the patients with more than a 10-year progression of ulcerative colitis had an annual colonoscopy. Yearly kidney function was registered in 57.1% of the patients, 92.9% had a yearly complete blood count, and 78.6% had yearly liver function tests. A total of 34.8% of patients had no bone densitometry in their case records. CONCLUSIONS: These results are a red flag suggesting the need to reinforce the role of the primary healthcare providers in relation to vaccination follow-up and the need to improve the education of the patient in relation to inflammatory bowel disease.
