Abstract
Pediatric obsessive-compulsive disorder (OCD) is prevalent in 1% to 2% of the population. Emerging studies have correlated non-celiac gluten sensitivity with psychiatric conditions such as schizophrenia, depression, mania, and anxiety. This case study is the first reported case of OCD associated with non-celiac gluten sensitivity. The objectives of this case report are to (1) identify gluten sensitivity as a possible contributing factor to OCD in some patients; and (2) point out the possible benefit of an integrative medicine approach to the management of OCD in a patient with suboptimal benefit from a standard treatment regime. A 7-year-old male treated at a multi-physician integrative medicine practice in the United States had marked reduction of OCD symptoms and anxiety along with marked improvement of social behavior and school work after treatment consisting of gluten avoidance and other integrative medicine modalities. The patient's rapid response without side effects behooves the medical research community to further investigate the association of non-celiac gluten sensitivity and pediatric OCD.
Introduction
Obsessive-compulsive disorder (OCD) has a prevalence of 1% to 2% in the pediatric population. The standard treatment approaches are cognitive behavioral therapy, selective serotonin reuptake inhibitors (SSRIs), or both. 1 In a systematic review, Bloch et al reported that as many as 50% of patients treated with SSRIs alone do not achieve a satisfactory response. 2 In clinical trials SSRIs have an associated suicidal adverse event rate (suicidal ideation or suicide attempts) of 1% vs 0.3% in placebo groups. 1
In recent years, gluten sensitivity (GS) has emerged as a distinct disorder from celiac disease (CD). While CD occurs in about 1% of the general population, GS has an estimated prevalence 6-fold greater than that of CD. 3 CD is a well-described disease involving an immune-mediated reaction to gluten, a protein present in wheat, barley, and rye. It is characterized by an inflammatory reaction in the small bowel to protein fractions of gluten: gliadin, a monometric protein, and glutenins, aggregated proteins. 4 Symptoms of patients with CD include postprandial bloating, steatorrhea, and weight loss. 5 The diagnosis of CD is suggested by the presence of serum anti-gluten antibodies such as anti-tissue transglutaminase immunoglobulin A (IgA). 6 Confirmation of the diagnosis classically requires a histological finding on duodenal biopsy of crypt hyperplasia, villous atrophy, and increased intraepithelial lymphocytes. Furthermore, the genetic basis of CD is well described and includes haplotypes HLA-DQ2 and HLA-DQ8.
While GS involves symptoms that are also triggered by ingestion of gluten, both the presentation of the illness and the diagnostic findings can be different from CD. In GS, there is usually an absence of celiac-specific antibodies, intestinal villous atrophy, variable human leukocyte antigen expression, and variable presence of anti-gliadin antibodies. This subset of GS is now referred to as non-celiac GS. 7 While patients with CD and non-celiac GS typically report intestinal symptoms correlated with the illness, there is increasing public interest as well as growing medical evidence which suggests extra-intestinal manifestations that may include psychiatric illness and neurological disease.3,4,8
We present here the case of a 7-year-old male with severe OCD successfully treated at a multi-physician integrative medicine practice in the United States using gluten avoidance and other integrative medicine modalities.
Case Presentation
History of Present Illness
A 7-year-old white male with a 3-year history of anxiety and obsessive-compulsive behavior presented to a multi-physician suburban integrative medicine practice. The patient's mother reported that when the boy was 2 years old, she started receiving daily incident reports from his daycare of his pushing other children and violent outbursts. A child psychologist evaluated his behavior as normal. At age 3.5 years, the child began to be fearful and dependent. He started expressing severe separation anxiety, refusing to enter any room alone, including the bathroom. He was increasingly irritable and had trouble interacting with other children. When the patient was 5 years of age, his teacher noted that he had obsessive thoughts about “germs” and developed compulsive hand-washing. He avoided going near trash cans because he was afraid of “germs.” He expressed fear of his feces and would only go to the bathroom if he were completely undressed. He expressed irrational fears of getting “lead poisoning” and developed a related phobia toward pencils, to the extent that he was unable to sit at a table where a pencil was present. He did not want to play with other children because he was scared that he would hurt them. Whenever he coughed from a mild upper respiratory infection, he feared that he was going to stop breathing and became preoccupied with death. The patient was taken to a child psychologist and diagnosed with OCD and anxiety disorder. He was started on cognitive behavioral therapy, which included play therapy, exposure therapy, and other goal-directed therapy that resulted in mild improvement of his condition.

Treatment Costs
The patient's mother paid for all treatment costs as none of the treatments was covered under her insurance. Total treatment costs were less than $1000 (Table 2).

Discussion
We describe a case of a 7-year-old boy with severe OCD who responded remarkably well to a multi-pronged, relatively inexpensive integrative approach including a gluten-free diet. Reports have correlated non-celiac gluten sensitivity with psychiatric conditions such as schizophrenia, depression, mania, and anxiety.3–5 A literature review of PubMed, Web of Science, and PsychINFO revealed 1 reported case of an association of OCD with celiac disease (CD). 28 The presented case study is the first to the best of our knowledge to report a therapeutic response from a gluten-free diet in a non-celiac gluten sensitive patient with OCD.
The patient presented in this report was typical for this integrative medicine physician group practice in that a long period of standard treatment did not result in a satisfactory outcome. The aim of the practitioners is to get patients well expeditiously in a manner that the practitioner would choose for self or family. Thus multiple treatment methods are used simultaneously within the integrative medicine tenet that multiple factors may be involved in the maintenance of disease chronicity. As a number of therapies were applied simultaneously, it is uncertain which one(s) was/were most important. Based on our clinical expertise, we feel that treating the gluten issue was a dominant factor in the successful outcome. The observation that inadvertent gluten re-exposure was associated with an increase in symptoms supports this. One could also hypothesize that the resolution of symptoms was a placebo effect or spontaneous remission. However, the child had received multiple treatments over a 2-year period from the primary care physician, psychologists, and occupational therapists that could have shown a placebo effect but there was no improvement.
The other salient observation in this case report was the utility of ART pointing to the gluten problem. Non-celiac gluten sensitivity can be problematic to detect. The positive ART finding helped motivate the family to adopt the gluten-free prescription for diet and personal care products. ART9–11 was developed by Dietrich Klinghardt and Louisa Williams, 29 who built upon different forms of applied kinesiology described by Goodheart, 30 Omura16,31 and others.
Applied kinesiology is a form of manual muscle testing in which an interpretation is made regarding the response (weakness, no change, or strengthening) of a muscle to manual testing. The interpretation informs the assessment of the patient and the prediction of positive, negative, or neutral responses to therapies. Different forms of applied kinesiology can give different results. There are no published studies that have evaluated ART's reliability and validity.
The main limitation is that this is a single case report. However, given the remarkable improvement in this usually recalcitrant condition, we believe our findings justify further investigation of integrative medicine treatment approaches, particularly the role of a gluten-free diet, in the treatment of pediatric OCD.
