Comprehensive Guide to Managing Autism - 3

Leaky Gut

In a test of 36 autistic children reported by Repligen Corporation, 75% had a greater than normal pancreatic response to secretin infusion, especially among those with diarrhea (whose stool improved in consistency for several weeks afterward). These children are probably producing too little secretin, and thus receptor sites have proliferated. Human secretin receptor is a G-protein-coupled receptor that is functionally linked to the cAMP second messenger system by stimulation of adenylate cyclase (Ng et al, 1999). When given secretin, there is overactivity of the pancreas. I.V. Secretin causes a five-fold increase in the output of IGF-1 in pancreatic fluid. They also documented a pattern of intestinal inflammation (esophagitis, gastritis, and duodenitis that would greatly hinder absorption of nutrients) in the majority. The most frequent gastrointestinal complaints were chronic diarrhea, gaseousness, and abdominal discomfort and distention. Histologic examination in these 36 children revealed grade I or II reflux esophagitis in 25 (69.4%) with symptoms of wakefulness with irritability or crying, pressing of the lower abdomen, and diarrhea. Chronic gastritis was detected in 15, and chronic duodenitis in 24. Low intestinal carbohydrate digestive enzyme (amylase) activity was reported in 21 children (58.3%), although there was no abnormality found in pancreatic function. Thirty-nine percent were deficient of the enzyme Lactase, and thus had digestive problems with milk, with bloating, gaseousness, and a loose stool (these symptoms can be alleviated with a digestive enzyme supplement containing lactase). None showed signs of Helicobacter Pylori infection, or of fungal or bacterial overgrowth even in the one-third with suspected fungal or bacterial overgrowth based on urine acid test results.  

Your doctor has probably forgot a simple, inexpensive, urine test the doctor can make in office that uncovers toxic bacteria. Ask for a “urinary indican” test. Indican is created when the essential amino acid tryptophan is fermented by harmful bacteria in the bowel. If the indican test is positive, decrease intake of sugar and high glycemic carbohydrates because eating these things encourage overgrowth of many types of unfriendly critters, including candida. Supplement friendly flora to crowd out the nasties.  

This inflamed gut (dubbed “Leaky Gut” because it has become porous allowing large, food particles both protein and undigested starch to pass unnaturally into the blood) produces a number of symptoms. Increased intestinal permeability (IP) may reflect damage to the microvilli, which can reduce levels of lactase, the enzyme needed to digest milk sugar, eventually triggering osmotic diarrhea. Once this disease process starts, small bowel mucosal damage, indicated by higher IP ratios, remains “an important factor” associated with increased acidosis, hypokalemia (lack of potassium), iron deficiency, dehydration, and parasitic infection. Sucrose (table sugar) leaks into the blood, and this abnormal sugar in the blood stream causes a host of problems. Particles [especially from milk (casein) and grains (gluten/gliadin)] called peptides pass through the “Leaky Gut”, and activate the immune system creating many allergic symptoms, and also creating opioids in the brain that cause much of the “weird” behavior. Dermorphin and other opioid-like peptides can reduce stomach acid output (by inhibiting a zinc-bearing enzyme needed to make HCl), and change emptying time for the stomach, and therefore, hamper digestion. Undigested particles of undercooked grain starches pass into the blood and to the capillaries where they slow and clog blood circulation. Collateral circulation is likely enough to keep the organ functioning, but in the brain, neurons may be lost. This is why digestive enzymes are so vital to break down these protein and starch particles before they reach the gut.    

Mothers are often perplexed when, having been on Gf/Cf for a period, they find high levels of peptides still present. When a person goes Gf/Cf the body takes the opportunity to dump these things in the blood/urine again. That is why we see them in the urine for some time afterwards. In celiac literature, it speaks of taking 7 years to totally clear the system! “Treatment of the latter (candida) with conventional synthetic antifungal agents often causes impairment of liver detoxification functions, and a decrease in synthesis of phospho-sulfotransferase, an enzyme necessary to cleave food proteins, e.g., casein, into smaller easily absorbable peptides.”—Dr. Hugh Fudenberg, MD. Thus, fungicides exacerbate the opioid problem, and increase the potential for toxicity in PST kids. Of utmost significance is the observation that those eating soy proteins or drinking soy milk may also have high peptide readings in their urine. Soy proteins are used extensively as emulsifiers, binders, and stabilizers in meat, poultry, snack foods, sausage, frozen spaghetti, and whipped toppings. Textured vegetable protein is soy-based, and many meat substitutes are soy-based. It has been found that those on soy may have high values of gliadorphin and casomorphin, presumably because of peptides from soy that are similar or identical to those in gluten or casein (Zhang XZ, Wang HY, Fu XQ, Wu XX, Xu GL. Bioactive small peptides from soybean protein. Anri NY, Acad Sci 1998 Dec 13, 864: 640-5.  

Additionally, those on SerenAid™ or EnzymAid™ may show high peptide values in the urine. This may be because these products are interfering with the test. 

Are the symptoms being suffered symptoms of “autism”, or of malnutrition, toxicity, and immune changes induced by that chronically inflamed, out of balance, gastrointestinal tract? Can nutritional intervention ameliorate these “autistic” symptoms?
