A Study of Moderate to Severe Inflammatory Bowel Disease, Including Ulcerative Colitis (UC) and Crohn's Disease (CD)

Percentage of participants with active CD observed, where active CD was defined as Harvey Bradshaw index (HBI) greater than or equal to (>=) 8 or Crohn's disease active index (CDAI) >=220. CDAI assessed CD based on clinical signs and symptoms such as number of liquid stools, intensity of abdominal pain, general wellbeing, presence of comorbid conditions, use of antidiarrheal, physical examination and laboratory findings. Total score ranges from 0 to 600 points. Higher score indicates more severe disease. HBI score was used to measure disease activity of CD and consisted of 5 clinical parameters: general well-being, abdominal pain, number of liquid stools per day, abdominal mass, and complications. Total score is sum of individual parameters. Score ranges from a minimum score of 0 to no pre-specified maximum score as it depends on number of liquid stools, where higher scores indicate more severe disease. Percentages are rounded off to whole number at the nearest decimal.

Percentage of participants with active disease UC disease will be observed, where UC is defined as 9-point Partial Mayo Score (pMayo score) >=5. The Mayo score is composed of four categories (bleeding, stool frequency, physician assessment, and endoscopic appearance) rated from 0-3 that are summed into a total score ranging from 0-12. pMayo score consists of 3 sub scores: stool frequency, rectal bleeding, and physician global assessment of disease severity, each graded from 0 to 3. These scores are summed to give a total score range of 0 to 9; where higher scores indicating more severe disease. The pMayo score when compared with the full Mayo score and categorizes UC patients as being in remission (score of 0 to 2), having mild activity (pMayo of 3 or 4) or moderate to severe activity (pMayo of >=5).

Number of participants will be reported based on the clinical presentations (location, behavior, perianal disease, achievement of ileal disease and extraintestinal manifestations for CD participants). Clinical presentations that have data for at least one participant in the below categories are reported. Data is reported for participants with CD only.

Number of participants will be reported based on the clinical presentations (location, behavior, and extraintestinal manifestations,). Clinical presentations that have data for at least one participant in the below categories are reported. Data is reported for participants with UC only.

Number of participants will be reported based on the IBD therapies which include aminosalicylates, steroids, immunomodulators, immunosuppressants, biologics, antibiotics, probiotics, and surgeries. A participant can receive more than one IDB therapy.

Time between the beginning of IBD therapy until the end of treatment or Day 1, whichever comes first. IBD therapies include aminosalicylates, steroids, immunomodulators, immunosuppressants, biologics, antibiotics, probiotics, and surgeries.

Percentage of participants who have experienced any biologic therapy (examples, infliximab, adalimumab, golimumab, ustekinumab, certolizumab) once or more than once according to medical history until the day 1. Percentages are rounded off to the nearest single decimal.

CDAI assessed clinical signs and symptoms: number of liquid stools, intensity of abdominal pain, general wellbeing, presence of comorbid conditions, use of antidiarrheal, physical examination and laboratory findings. Total score ranges from 0-600 points. Higher score indicates more severe disease. HBI score measures disease activity of CD based on 5 clinical parameters: general well-being, abdominal pain, number of liquid stools/day, abdominal mass, and complications. Total score is sum of individual parameters. Score ranges from a minimum score of 0 to no pre-specified maximum score as it depends on number of liquid stools, where higher scores indicate more severe disease. Socio-demographic variables included age, sex, professional status, educational level, participant income. Clinical variables included duration and age at diagnosis, steroid dependence or refractoriness, family history, medical history and comorbidities, criteria used for diagnosis, calprotectin and EIM.

Mayo score is composed of 4 categories (bleeding, stool frequency, physician assessment, and endoscopic appearance) rated from 0-3 that are summed into a total score ranging from 0-12. pMayo score consists of 3 sub scores: stool frequency, rectal bleeding, and physician global assessment of disease severity, each graded from 0 to 3. These scores were summed to give a total score range of 0 to 9; where higher scores indicating more severe disease. The pMayo score when compared with the full Mayo score and categorizes UC patients as being in remission (score of 0-2), having mild activity (pMayo of 3-4) or moderate to severe activity (pMayo >=5). Socio-demographic variables included age, sex, professional status, educational level, participant income. Clinical variables included duration and age at diagnosis, steroid dependence or refractoriness, family history, medical history and comorbidities, criteria used for diagnosis, calprotectin and extraintestinal manifestations (EIM).

SF-36 is a general quality of life (QoL)-questionnaire, which evaluates 8 health dimensions: physical functioning, bodily pain, role physical (limitations due to physical problems), role emotional (limitations due to personal or emotional problems), mental health, social functioning, vitality, and general health perceptions. Based on these 8 dimensions, two weighted scores were generated: the physical component summary (PCS) score and the mental component summary (MCS) score. Scores range between 0 and 100, with higher scores indicating a better quality of life. Mean score of each component (physical component and mental component) was reported.

The IBDQ was a 32-item questionnaire that measured 4 dimensions: bowel function, emotional status, systemic symptoms, and social function. Within dimensions, each question presented seven possible answers/points. Each domain score was the sum of 8 responses each ranging from 1 to 7, where 1 indicated worst function and 7 the best. The sub-score ranged from 8 to 56 and thus the total score ranged from 32 to 224, where higher score indicating better quality of life.

WPAI assessed the impact of IBD on work productivity and daily activities during the previous 7 days. The WPAI included 6 questions: 1 (if currently employed); 2 (hours missed due to disease); 3 (hours missed other reasons); 4 (hours actually worked); 5 (degree disease affected productivity while working); 6 (degree disease affected regular activities). WPAI generated four component scores: percentage of work time missed (absenteeism); percentage of impairment while working (presentisms); percentage of overall work impairment (absenteeism and presentisms combined); and percentage of activity impairment. Scores for WPAI range from 0% to 100%, where 0 % indicates no impairment and 100% is total loss of work productivity/activity. Employed participants were evaluated for this outcome measure. Mean total percentage of work impairment (absenteeism and presentisms) were reported in terms of hours.

A cost analysis of Ulcerative Colitis (UC) and Crohn's Disease (CD) was developed, classified by severity as mild and moderate-severe for each of the conditions. Direct medical costs were considered and included the following items: associated comorbidities, intestinal manifestations, surgical procedures, emergency visits, hospitalizations, medical appointments, follow-up studies, and previous pharmacological treatments; this was collected in the study including the number of participants and the proportion of them that presented the items studied. The total direct medical cost for all participants with each of the conditions was obtained, with the average 3-year cost per participant for UC and for CD multiplied by the number of all participants with UC and CD respectively. So, the values reported in the data table below represent the total direct cost for all participants with UC and CD respectively. The total direct cost was in Mexican Peso(MXN).

A cost analysis of UC and CD was developed, classified by severity as mild and moderate-severe for each condition. Indirect cost was estimated by using number of hours missed from work (absenteeism) multiplied by average hourly labor cost including wages and benefits, to calculate average lost productivity cost per participant due to absenteeism during specified duration. Hours missed from work were assessed by Work Productivity and Activity Impairment Questionnaire: General Health (WPAI-GH) questionnaire, in which respondents answered 6 questions related to work productivity and impairment.The indirect medical cost for all participants with each of the conditions was obtained,with the average 3-year cost per participant for UC and for CD multiplied by the number of all employed participants with UC and CD respectively. So, values reported in data table below represent the indirect cost in totality for all employed participants with UC and CD respectively. The indirect cost is in MXN.
