Dr. Bonney Reed: Optimizing Quality of Life in IBD

We had a terrific lecture given to our group by Dr. Bonney Reed. She is a pediatric psychologist with a clinical and research focus on children with inflammatory bowel disease. Our group has worked closely with Dr. Reed for many years. Many of her slides are included below along with my notes; my notes may contain errors in transcription and in omission.

  • GI symptoms may begin as the result of organic disease (e.g., IBD). Anxiety and chronic activation of the stress response system may lead to alterations in the brain, spinal cord, and gut increasing the load of GI symptoms. In turn, distress associated with GI symptoms may contribute to anxiety or depressed mood, creating a cycle of worsening GI symptoms and overall psychological distress.
  • Consistent with a brain-gut axis model, individuals with IBD, compared to healthy controls, demonstrate dysfunction of the ANS indicative of a chronic stress response which is characterized by increased sympathetic nervous system (SNS) activity and reduced parasympathetic nervous system (PNS) activity
  • Psychological factors are the key factor for pediatric patients with IBD when self-rating their global health
  • Factors that contribute to an individual’s current QoL: symptom exacerbation, psychological functioning including stress, and family support.
  • Health-related quality of life factors: major life transitions (eg. graduating high school and needing to manage IBD at college), fatigue ( persists despite controlled inflammation), poor body image (especially with weight changing rapidly), a diminished self-perception or seeing oneself as less capable, comorbid functional abdominal pain (about a quarter of youth with IBD), and food restrictions that can interfere with daily quality of life.
  • Stress plays important role influencing (bidirectional) disorders of brain gut interaction (DBGI)
  • Dr. Reed’s research includes a longitudinal cohort of newly-diagnosed (w/in 45 days) pediatric patients with IBD. This cohort undergoes psychosocial assessment along with ANS assessment
  • Emotional reactivity indicates individuals with a ‘short fuse’ who take longer to return to normal.  Those with emotional reactivity are at increased risk for anxiety/depression.
  • Skin conductance response (SCR) can help determine autonomic nervous system (ANS) dysfunction.  It is a measure of sympathetic arousal and stress
  • Stressful life events increase the rates of depression and correlate with skin conductance at medium and high levels
  • Within this model, Dr. Reed’s research focuses on the hypothesis that autonomic dysfunction is indicative of a chronic stress response. This, in turn, contributes to increased sympathetic nerve activity and decreased parasympathetic activity. This contributes to symptoms of anxiety and depression as well as GI clinical symptoms, all of which lead to impairments in QoL. Addressing autonomic dysfunction may provide a mechanism by which to address all of these QoL drivers
  • ANS dysfunction (which is also seen in cyclic vomiting syndrome) can improve with biofeedback focused heart rate variability (HRV). HRV, in turn, is associated with increase inflammation
  • Preliminary data from breath pacer intervention has shown in improvement in multiple variables

How Effective are the Treatments for Functional Abdominal Pain?

Posted on by

According to a recent systematic review (Korterink JJ et al. J Pediatr 2015; 166: 424-31), “there is no evidence to support routine use of any pharmacologic therapy” for pediatric functional abdominal pain (FAP).  How many pediatric gastroenterologists want to discuss this conclusion with their patients?

How did the authors reach their conclusion?

Design: The authors screened 557 articles and ultimately identified only four articles with a total of 6 studies met inclusion criteria which included the following:

  • systemic review or randomized control trial
  • children 4-18 years
  • diagnosis of FAP established with well-defined criteria
  • intervention was compared to placebo or alternative treatment

Results: All of the studies were reviewed –each received an overall quality rating by the authors as “very low.” The particular treatments included amitriptyline, peppermint oil, famotidine, miralax, tegaserod, and cyprohepatadine.  The study with the most patients had only 90 patients and the longest treatment period was 4 weeks.

In the discussion, the authors make several key points:

  • there is a lack of adequately powered, high-quality, placebo-controlled drug trials in children with FAP
  • weak evidence was found in support of peppermint oil, cyproheptadine, and laxatives at reducing pain; amitriptyline and famotidine had weak evidence supporting some improvement in global symptoms or quality of life.
  • problems with the studies: small sample sizes, poorly reported side effects, lack of follow-up, risk of bias
  • “several nonpharmacologic therapies (e.g.. hypnotherapy and cognitive behavioral therapy) have shown their efficacy in treating children with” FAP…with success rates up to 85%.  Moreover, these therapies are not hampered by severe side effects.”

Bottomline: Our office-based psychologist may be more helpful for our patients than all the medications combined.

Amplified Pain Syndromes in Children

Posted on by

A recent review (Curr Opin Rheumatol 2014; 23: 1-12 -thanks to our pain team for sending reference) makes a number of important points regarding the pathogenesis and management of amplified pain syndromes (APS).

Table 1 lists the diagnosis and pain presentations.  These include complex regional pain syndromes, juvenile fibromyalgia, diffuse idiopathic pain, concomitant conditions (including irritable bowel syndrome, chronic fatigue syndrome, interstitial cystitis, chronic headache, functional abdominal pain, and conversion symptoms/disorder).

Key points:

  • Pediatric APS are widespread and under-recognized
  • Pathophysiology is complex with numerous contributors “including central sensitization, abnormal cytokine production, sympathetic-sensory disorders, autoimmune responses, altered blood flow, genetic predisposition, and psychosocial factors.”
  • “The clinical effectiveness of medication management in pediatric APS remains unclear and controversial.”  It is noted that preoperative gabapentin and pregabalin may reduce the incidence of chronic post surgical pain (in adults); this has not been documented in a pediatric population.
  • “Exercise-based and cognitive-based treatments remain the cornerstone of therapy.” Intensive multidisciplinary pain rehabilitation “restores functioning rapidly, reduces pain in the long run, improves comorbid psychological distress, and reduces medical utilization.”
  • Potential elements of treatment noted in Table 2 (geared more towards rheumatology), including exercise, desensitization, self-regulation (eg. diaphragmatic breathing, guided imagery), and stress management/counseling.

Bottomline: For children with severe pain symptoms, multidisciplinary pain teams can be very helpful.  However, there is not a simple pill that will fix everything.
