Introduction: Muscle Fasciculations

There are 3 known types of negative reactions to wheat proteins, collectively known as wheat protein reactivity: wheat allergy (WA), gluten sensitivity (GS), and celiac disease (CD). Of the 3, only CD is known to involve autoimmune reactivity, generation of antibodies, and intestinal mucosal damage. Wheat allergy involves the release of histamine by way of immunoglobulin (Ig) E cross-linking with gluten peptides and presents within hours after ingestion of wheat proteins. Gluten sensitivity is considered to be a diagnosis of exclusion; sufferers improve symptomatically with a gluten-free diet (GFD) but do not express antibodies or IgE reactivity.1

The reported prevalence of WA is variable. Prevalence ranges from 0.4% to 9% of the population.2,3 The prevalence of GS is somewhat difficult to determine, as it does not have a standard definition and is a diagnosis of exclusion. Gluten sensitivity prevalence of 0.55% is based on National Health and Nutrition Examination Survey data from 2009 to 2010.4 In a 2011 study, a GS prevalence of 10% was reported in the US population.5 In contrast to the above 2 examples, CD is well defined. A 2012 study examining serum samples from 7798 patients in the National Health and Nutrition Examination Survey database from 2009 to 2010 found an overall prevalence of 0.71% in the United States.6

Neurologic manifestations associated with negative reactions to wheat proteins have been well documented. As early as 1908, “peripheral neuritis” was thought to be associated with CD.7 A review of all published studies on this topic from 1964 to 2000 indicated that the most common neurologic manifestations associated with GS were ataxia (35%), peripheral neuropathy (35%), and myopathy (16%). 8 Headaches, paresthesia, hyporeflexia, weakness, and vibratory sense reduction were reported to be more prevalent in CD patients vs controls.9 These same symptoms were more prevalent in CD patients who did not strictly follow a GFD vs those who were compliant with GFD.

At present, there are no case reports describing the chiropractic management of patient with gluten neuropathy. Therefore, the purpose of this case study is to describe a patient presentation of suspected gluten neuropathy and a treatment protocol using dietary modifications.

Case Report

A 28-year-old man presented to a chiropractic teaching clinic with complaints of constant muscle fasciculations of 2 years’ duration. The muscle fasciculations originally started in the left eye and remained there for about 6 months. The patient then noticed that the fasciculations began to move to other areas of his body. They first moved into the right eye, followed by the lips, and then to the calves, quadriceps, and gluteus muscles. The twitching would sometimes occur in a single muscle or may involve all of the above muscles simultaneously. Along with the twitches, he reports a constant “buzzing” or “crawling” feeling in his legs. There was no point during the day or night when the twitches ceased.

The patient originally attributed the muscle twitching to caffeine intake (20 oz of coffee a day) and stress from school. The patient denies the use of illicit drugs, tobacco, or any prescription medication but does drink alcohol (mainly beer) in moderation. The patient ate a diet high in meats, fruits, vegetables, and pasta. Eight months after the initial fasciculations began, the patient began to experience gastrointestinal (GI) distress. Symptoms included constipation and bloating after meals. He also began to experience what he describes as “brain fog,” a lack of concentration, and a general feeling of fatigue. The patient noticed that when the muscle fasciculations were at their worst, his GI symptoms correspondingly worsened. At this point, the patient put himself on a strict GFD; and within 2 months, the symptoms began to alleviate but never completely ceased. The GI symptoms improved, but he still experienced bloating. The patient’s diet consisted mostly of meats, fruit, vegetables, gluten-free grains, eggs, and dairy.

At the age of 24, the patient was diagnosed with WA after seeing his physician for allergies. Serum testing revealed elevated IgE antibodies against wheat, and the patient was advised to adhere to a strict GFD. The patient admits to not following a GFD until his fasciculations peaked in December 2011. In July of 2012, blood work was evaluated for levels of creatine kinase, creatine kinase–MB, and lactate dehydrogenase to investigate possible muscle breakdown. All values were within normal limits. In September of 2012, the patient under- went food allergy testing once again (US Biotek, Seattle, WA). Severely elevated IgG antibody levels were found against cow’s milk, whey, chicken egg white, duck egg white, chicken egg yolk, duck egg yolk, barley, wheat gliadin, wheat gluten, rye, spelt, and whole wheat (Table 1). Given the results of the food allergy panel, the patient was recommended to remove this list of foods from his diet. Within 6 months of complying with the dietary changes, the patient’s muscle fasciculations completely resolved. The patient also experienced much less GI distress, fatigue, and lack of concentration.

Discussion

The authors could not find any published case studies related to a presentation such as the one described here. We believe this is a unique presentation of wheat protein reactivity and thereby represents a contribution to the body of knowledge in this field.
