What is the recommended monitoring schedule for a patient with Crohn's disease in remission on Humira (adalimumab) since 2018, with comorbidities including hypertension, anxiety, Benign Prostatic Hyperplasia (BPH), chronic pelvic pain, and chronic prostatitis?

From the Guidelines

For a patient with Crohn's disease in remission on Humira since 2018, with comorbidities including hypertension, anxiety, BPH, chronic pelvic pain, and chronic prostatitis, the recommended monitoring schedule should include regular assessments of disease activity, biomarkers, and comorbidities, with a focus on minimizing the risk of relapse and managing comorbid conditions. The patient should have quarterly visits with their gastroenterologist for the first year of stable remission, then semi-annual visits if remission continues, as suggested by 1. Each visit should include:

• Assessment of disease activity using standardized tools such as the Crohn's Disease Activity Index (CDAI) or Harvey-Bradshaw Index (HBI) 1
• Laboratory tests including complete blood count, liver function tests, C-reactive protein, and fecal calprotectin, which can help identify potential relapse or complications 1
• Annual tuberculosis screening with a PPD skin test or QuantiFERON-TB Gold test, as Humira increases the risk of tuberculosis 1
• Colonoscopy surveillance every 1-3 years, depending on disease duration and risk factors, to monitor for dysplasia or cancer 1
• Regular monitoring of blood pressure, with adjustments to hypertension management as needed
• Annual PSA testing and urological evaluation for BPH and prostatitis management
• Mental health assessment for anxiety at regular intervals
• Patients should report any new symptoms promptly, particularly infections, as Humira increases infection risk due to TNF-alpha inhibition. Biomarkers such as fecal calprotectin may be used to monitor disease activity and predict relapse, with elevated levels (>200-300 mg/g) indicating a higher risk of relapse 1. The use of biomarkers can help reduce the need for endoscopic or radiologic assessments, especially if these have been performed recently, and can guide treatment adjustments without the need for invasive procedures 1. Overall, this monitoring schedule prioritizes the patient's morbidity, mortality, and quality of life, while also considering the potential risks and benefits of Humira therapy and the management of comorbid conditions.

From the Research

Monitoring Schedule for Crohn's Disease Patient on Humira

The patient has been in remission since 2018 while on weekly Humira (adalimumab) for Crohn's disease, along with comorbidities including hypertension, anxiety, Benign Prostatic Hyperplasia (BPH), chronic pelvic pain, and chronic prostatitis.

• The monitoring schedule should include regular check-ups to assess the patient's clinical symptoms and biomarkers of intestinal inflammation, such as faecal calprotectin and C-reactive protein, as recommended by the study 2.
• The study 3 suggests that patients with Crohn's disease on adalimumab should be monitored for long-term sustained benefit, with assessment of clinical response to induction therapy after 3 months and sustained benefit of maintenance therapy calculated from Kaplan-Meier survival tables.
• The frequency of monitoring should be based on the patient's disease activity and treatment response, with more frequent monitoring for patients with active disease or those who have experienced a loss of response to treatment, as seen in the study 4.
• The patient's adalimumab drug levels and anti-adalimumab antibody levels should also be monitored, as high drug levels have been associated with disease remission and low antibody levels, as shown in the study 5.
• Additionally, the patient's comorbidities, including hypertension, anxiety, BPH, chronic pelvic pain, and chronic prostatitis, should be monitored and managed accordingly.

Comorbidities Management

• Hypertension: regular blood pressure checks and management with medication or lifestyle changes as needed.
• Anxiety: regular assessments of anxiety levels and management with medication, therapy, or lifestyle changes as needed.
• BPH: regular assessments of urinary symptoms and management with medication or lifestyle changes as needed.
• Chronic pelvic pain and chronic prostatitis: regular assessments of pain levels and management with medication, therapy, or lifestyle changes as needed.

Treatment Adjustments

• The patient's treatment regimen may need to be adjusted based on their response to therapy, with options including dose escalation or de-escalation of adalimumab, as seen in the study 4.
• The patient's treatment regimen may also need to be adjusted based on their comorbidities, with consideration of potential interactions between medications.
