Naturopathic Approaches to Care of Children and Adolescents with Asthma and Allergies Darin Ingels, ND, MT(ASCP) Ingels Family Health 2425 Post Road, Suite 100 Southport, CT 06890 [email protected] Who has allergies and asthma? According to the American Academy of Allergy, Asthma and Immunology, more than 50 million people in the U.S. have some form of allergy. Allergic diseases affect more than 20% of the population. Allergies are the 6th leading cause of chronic disease in the U.S. According to AAAAI, more than 10% of children under the age of 17 have allergic rhinitis and 8% have food allergies. According to the CDC, 7.1 million children have asthma in the United States (9.5% of all children). The incidence of asthma and allergies continues to rise each year. Pathophysiology of Asthma Asthma is defined as a chronic disease that involves inflammation of the pulmonary airways and bronchial hyperresponsiveness (bronchoconstriction) that results in lower airway obstruction. Gross pathology of asthmatic airway shows lung hyperinflation, smooth muscle hypertrophy, lamina reticularis thickening, mucosal edema, epithelial cell sloughing, cilia cell disruption and mucus gland hypersecretion. Microscopic pathology shows increased numbers of eosinophils, neutrophils, lymphocytes and plasma cells in the bronchial tissues, bronchial secretions and mucus. Pathophysiology of Asthma Activated CD4 T-cells recruit leukocytes from the bloodstream to the airway and direct the release of proinflammatory cytokines, including IL-1, IL-4, IL-5, IL-6, IL-13 and TNF-α. IL-4 with IL-13 signals the switch from IgM to IgE antibodies, triggering mast cell degranulation and release of histamine, leukotrienes and other mediators that perpetuate inflammation and bronchoconstriction. IL-5 recruits and activates eosinophils which additionally perpetuate the inflammation. Histamine is the biggest factor in the acute phase of an asthma attack due to bronchoconstriction as well as increased vascular permeability. Pathophysiology of Asthma Prostaglandin D2 elicits further bronchoconstriction and vasodilation (which can potentially lead to hypotension). The late phase reaction (4-8 hours later) is mostly mediated by the presence of leukocytes which release a second wave of chemicals that continue to cause inflammation and bronchoconstriction. The presence of IgE in the acute and late phase reactions explains the often prolonged nature of asthma. Repeated inflammation of the airway causes structural damage and long-term remodeling of the airways, which may lead to further complications. Types of Asthma Extrinsic asthma (493.00) a. Atopic (Allergic): most common type of asthma triggered by environmental allergens such as dust, mold, pollen, foods, etc. b. Occupational: chemical inhalation c. ABPA: aspergillus spores Intrinsic Asthma (493.10) a. Nonreaginic: URI b. Cold or exercise induced c. Pharmacologic: drug-induced reactions, such as aspirin-induced asthma Asthma vs. RAD Reactive Airway Disease (RAD) is a term used to describe a multitude of obstructive airway symptoms, but is not necessarily asthma. RAD tends to be transient in nature, where asthma is a chronic condition. RAD does not necessarily need to have the inflammatory component and may only involve bronchoconstriction. Most children under the age of 5 are diagnosed with RAD as ascertaining a diagnosis of asthma is prohibitive. Only 30% of children under the age of 3 who wheeze will go on to develop asthma1 1. Medscape : http://emedicine.medscape.com/article/800119-overview Symptoms of childhood asthma • Wheezing (whistling sound) when breathing • Coughing, often worse at night or lying down • Tachypnea: be aware of norms for children Newborns: 30-60 bpm Toddlers: 20-40 bpm • Labored breathing • Complaints of chest hurting • Reduced energy • Feeling weak or tired Diagnosis of Asthma 1. Medical history: when symptoms occur, family history, other allergy symptoms, known triggers, pets, school exposure 2. Physical exam: wheezing, allergy signs, eczema 3. Spirometry is the gold standard test for diagnosing asthma, but not reliable for children under 5. Reduced FEV1, FVC which improves with bronchodilator. 4. Peak Flow Meter: reduced PEFR What Triggers Asthma? Allergens: inhaled (pollen, mold, dust, animal danders, etc.), food, sulfites/preservatives/MSG, medications, chemicals Infections GERD Tobacco smoke Exercise Cold Anxiety or emotional stress Differential Diagnosis of Asthma Asthma Croup or other viral infection Bronchiolitis/Bronchitis Epiglottitis Aspiration of foreign body Tracheo- or bronchomalacia Cardiac failure Pertussis: more than 25,000 cases in US Asthma: When to Refer to ER Cyanosis Dyspnea that does not respond to conservative treatment Tachypnea or tachycardia Change in mental status (hypoxia) Grunting Absent breath sounds on auscultation Drug Therapy for Asthma 1. Short-acting beta-2 agonist: albuterol (ProAir, Proventil, Ventolin), levalbuerol (Xopenex). Relaxes smooth muscle in airway and causes bronchodilation. Used as “rescue inhaler”. 2. Low dose inhaled corticosteroid: fluticasone (Flovent), budenoside (Pulmicort), mometasone (Asmanex), beclomethasone (Qvar). Inhibits inflmmatory cytokines and reduces inflammation. Drug Therapy for Asthma 3. Long-acting beta-2 agonist: not generally recommended for children. Have many side effects. Not used as solo therapy, but always in conjunction with steroid inhaler. Salmeterol (Serevent), formoterol (Foradil). Newer inhalers have combinations of low dose steroids and LABA’s such as fluticasone and salmeterol (Advair Diskus, Advair HFA), budesonide and formoterol (Symbicort), and mometasone and formoterol (Dulera). Drug Therapy for Asthma 4. Leukotriene receptor antagonists: monteleukast (Singulair), zafirlukast (Accolate). Selectively binds to leukotriene receptors, blocking the proinflammatory action of certain leukotrienes. However, many neuropsychiatric symptoms have been reported with children on monteleukast, so caution is advised. 5. Oral corticosteroids: prednisone, prednisolone (OraPred). Inhibits inflammatory cytokines. 6. Immune modulator: omalizumab (Xolair). SC injection given 2-4 times a week. Inhibits IgE binding to mast cells and basophils. Anaphylaxis is common, so rarely used. Drug Therapy for Asthma 7. Theophylline: methylxanthine that antagonizes adenosine receptors which leads to bronchodilation. Also has mild antiinflamatory effects. Has narrow therapeutic index and many side efects, so rarely used today. 8. Chromones: cromolyn sodium (Intal). Mast cell inhibitor. No longer commercially available in US, but can get in Canada. Can be compounded for nebulized treatment. Drug Therapy for Asthma Papadopoulos NG, et al. International consensus on (icon) pediatric asthma. Allergy 2012; 67: 976–997. What is Allergy? Allergy is defined as a harmful, increased susceptibility to a specific substance , also known as hypersensitivity. Typically used to describe type I or immediate hypersensitivity reactions, mediated by IgE, but may include types II, III and IV hypersensitivity. However, this definition does not encompass the breadth of immune reactions to substances. Anyone presenting with recurrent infections or multiple endocrine dysfunction should be evaluated for allergies. Common Allergens House dust mites Pollen (trees, grasses and weeds) Mold Animal danders (cat, dog, rabbit, etc.) Insects Foods (children): milk, egg, peanuts, wheat, soy, tree nuts Foods (adults): Peanuts, tree nuts, fish, shellfish Less Common Allergens Food components: histamine, tyramine, MSG, phenolics Food dyes, especially tartrazine (yellow #5) Chemicals: perfume, formaldehyde, phenol, petroleum, preservatives, tobacco smoke Medications Hormones, neurotransmitters? Do some of the body s proteins stimulate immune reactions? Classification of Hypersensitivity Adapted from Johansson SGO et al. Allergy 2001;56:813-24 Hypersensitivity Allergic hypersensitivity (Immunologic mechanism defined) IgE mediated Atopic Classic allergy Nonallergic hypersensitivity (Immunologic mechanism excluded) Non-IgE mediated T-cell Non-atopic (contact dermatitis, Celiac disease) Insect sting Parasites/Infection Eosinophillic reactions IgG-mediated (allergic alveolitis, food allergies?) Drugs Idiosyncratic Others Classification of Hypersensitivity Adapted from Johansson SGO et al. Allergy 2001;56:813-24 Hypersensitivity Allergic hypersensitivity (Immunologic mechanism defined) Enzymatic Food Intolerance (i.e. Lactose intolerance) Nonallergic hypersensitivity (Immunologic mechanism excluded) Pharmacologic Reactions (i.e. caffeine) Psychological Reactions (i.e. aversions to foods) Classical Allergy Symptoms Allergic rhinitis (hayfever) Sinusitis Allergic conjunctivitis Otitis media/Otitis interna Asthma Eczema Contact dermatitis Hives (urticaria) Gastroenteritis Other conditions that may suggest allergy Arthritis ADHD Bladder infections Candidiasis Canker sores Celiac disease Chronic infections Colic Constipation Depression Diarrhea Fatigue (Chronic) Gallbladder attacks GERD Glaucoma Hypertension Hypoglycemia Hypothyroidism IBS Inflammatory Bowel Dz Irregular menses Migraine headaches Obesity PMS Psoriasis Ulcers What Affects Allergies? Frequency of exposure Duration of exposure Dose of exposure Genetics: allergy has strong familial disposition Prenatal factors (smoking, alcohol, diet) Diet Lifestyle: Smoking, obesity, excessive alcohol consumption Underlying infection Stress Occupation: nail technician, mechanic, dental hygienist, etc. What Affects Allergies? Season (in most of U.S.) Winter: House dust mites, indoor mold, animal danders Spring: Tree pollen, outdoor mold Summer: Grass pollen, weed pollen, outdoor mold Fall: Weed pollen, outdoor mold Perennial: Food, animal dander, mold, house dust mites Physical Signs of Allergy Allergic shiners Dennie s Lines Allergic salute Eczema Runny nose Post-nasal drip Serous fluid accumulation in middle ear Allergic Shiners Allergic Salute Dennie s Lines Diagnosis of Allergies Skin Tests: Blood Tests: Prick/Puncture Test Intracutaneous Test Patch Test Total IgE RAST: Specific IgE IgG4 tests (foods) IgA (selective IgA deficiency) Diagnosis of Food Allergies 1. RAST (ImmunoCap®): specific IgE antibody test for a specific food. Most useful for diagnosing anaphylactic food allergies. 2. IgG antibody tests: specific IgG antibody test for a specific food. More likely to detect delayed reaction to a food or food substance. Better for diagnosing food intolerances or food sensitivities. 3. Oral challenge: Eliminate suspected food allergy for two to three weeks and then challenge the food back and look for symptoms. 4. Esoteric testing: EDS, muscle testing, NAET, AAT. These methods are NOT diagnostic, but may provide insight to how the body reacts to certain foods. Diagnosis of Allergies Provocation/Neutralization: Intradermal method of using serial 1:5 dilutions to provoke symptoms with one dilution and turning the symptoms off with the neutralizing dose. Used for foods. Serial endpoint titration (SET): Used for inhalants. *Esoteric Testing: Electrodermal screening (EDS), kinesiology, NAET, AAT. * These methods are not FDA approved as diagnostic methods, but may provide insight into one s allergies. Prevention of Allergies Clean Up The Home! 1. Dust mite protection: protective covers for mattress, pillows. Vacuum mattress regularly. Wash sheets weekly and other bedding regularly. Remove carpet from home. 2. No animals in bedroom. 3. Ventilate home frequently, especially bedroom. 4. Do not smoke in home. Wash clothes soon after exposure to smoke or other chemicals. 5. Use air purifiers: HEPA filter (with UV light if mold allergies). Change filters in furnace as often as needed. Tsitoura S, et al.

Morgan WJ, et al. Results of a home-based environmental intervention among urban children with asthma. N Engl J Med 2004;351:1068-80. Clean Up The Home! Reduce exposure to mold: • Eliminate sources of water leaking into home (especially basements). Fix water damaged areas appropriately. Test home for stachybotrys (toxic mold). • Clean mold in bathrooms, etc. with 10% bleach solution. Clean clothes with Borax if mildew. • Use dehumidifiers in areas of home that are over saturated. Home humidity should be ~ 40-50%. • Remove carpet and padding. Padding harbors mold more than carpet, especially if carpets have ever been steam cleaned. Clean Up The Home! Reduce exposure to chemicals: • Counsel patients on cleaning up their home and work environments. Home Safe Home by Dadd. • Lowering the exposure to chemicals reduces the load on the immune system. Safe cleaners to use in the home 1) 2) 3) 4) Arm and Hammer Baking Soda Bon Ami cleanser or Borax Water and white vinegar 70% isopropyl alcohol Clean Up The Diet Consume whole foods. Avoid foods that are canned, processed, refined. These foods may contain additives, preservatives, dyes. Eat organic when possible and available. Eat organic foods and foods that do not contain hormones or antibiotics. Our Toxic World by Rapp. Avoid known food allergens. Mind the gut. Changes in gut microflora may regulate immune responses in the lungs1. Overuse of antibiotics and chronic intestinal inflammation may predispose to microflora imbalances. 1 Noverr MC, Noggle RM, Toews GB, Huffnagle GB. Role of antibiotics and fungal microbiota in driving pulmonary allergic responses. Infect Immun 2004;72:4996-5003. Clean Up The Lifestyle If overweight, lose weight. Obesity predisposes to allergies and asthma in 1 2 children and losing weight reduces hypersensitivity . Reduce stress. Stress decreases secretory IgA, which may increase risk of 3 mucosal infections . Get off the phone? Study found one hour of continuous cell phone use had a significant increase in the allergic skin response to dust and cedar pollen, compared with those who did not use a cell phone4. 1O Connell EJ.

Conventional Treatment/Prevention Antihistamines: H1 receptor antagonists. Cetirizine (Zyrtec®), diphenhydramine (Benadryl®), loratidine (Claritin®), fexofenadine (Allegra®). Decongestants: pseudoephedrine (Sudafed®). Nasal sprays: oxymetazoline (Afrin®), cromolyn sodium (NasalCrom®). Steroids: nasal, inhaled, topical. Triamcinolone (Nasacort®), fluticasone (Flonase®), budesonide (Rhinocort®), hydrocortisone (Cortaid®). Leukotriene inhibitors: montelukast (Singulair®). Immunotherapy: weekly or monthly allergy shots. Conventional Treatment: Good News, Bad News Good News Will often control symptoms rapidly. Can prevent life-threatening situations. Do not require frequent office visits, unlike immunotherapy. Bad news Many side effects. Can interfere with ones daily activities. Does not address underlying cause or immune dysfunction. May cause further immune suppression or dysregulation (steroids). Masks triggers that might be identifiable and avoidable. Risk of anaphylactic reaction. Frequent office visits if doing allergy shots. Treatment of Allergies and Asthma Treatment Goals for Allergies and Asthma Treatment Goals: 1. Identify the allergen. Avoid or minimize substance exposure. 2. Reduce the total load. Eliminate other factors that influence the immune system. 3. Improve immune function with non-suppressive means (nutrients, herbs, homeopathy, etc.). 4. Detoxification 5. Immunotherapy: non-injection, isopathy. Can alter the way the immune system responds to an allergen. Cromolyn sodium Semi-synthetic bioflavonoid that inhibits degranulation of mast cells. Can be used intranasally (NasalCrom®), inhaled (Intal®) or orally (Gastrocrom®). Used to treat allergic rhinitis, asthma and food allergies. Excellent safety profile. No known drug interactions.

Magnesium Small study showed children have lower RBC magnesium levels during an acute asthma attack, but not plasma magnesium and the RBC magnesium level return to normal after treatment1. The severity of the attack was directly proportional to the degree of hypomagnesemia. Oral magnesium supplementation 300 mg/day in 37 children in inhaled fluticasone (and salbutamol) reduced bronchial reactivity to methacholine, diminished allergen-induced skin responses and provided better symptom control than those on medication alone.2 Magnesium may have mild anti-histamine effects, so possible benefits for allergic rhinitis. 1 Amin 2 M, et al. Magnesium concentration in acute asthmatic children. Iran J Pediatr 2012;22:463-7. Gontijo-Amaral C, et al.. Oral magnesium supplementation in asthmatic children: a double-bilnd randomized placebo controlled trial. Eur J Clin Nutr 2007;61:54-60. Magnesium IV magnesium sulfate (25 mg/kg with max 2g) was found to be useful when administered to children within the first hour of an acute asthma attack.3 The number of children requiring mechanical ventilation support was 4% in the treatment group compared with 33% in the control group. Nebulized magnesium sulphate and salbutamol significantly increased peak flow, compared with those treated with nebulized saline and salbutamol in the treatment of acute severe asthma.4 3 Torres S, et al.

Mymensingh Med J 2013;22:1-7. Vitamin E Vitamin E appears to have mild leukotriene inhibition1. 112 adults with allergic rhinitis had significant improvement in nasal symptoms after taking 800 IU/d of vitamin E for 10 weeks2. A diet high in vitamin E decreases the risk of developing hayfever3. 1 Centanni S, et al. The potential role of tocopherol in asthma and allergies: modification of the leukotriene pathway. BioDrugs 2001;15:81-6. 2 Shahar E, Hassoun G, Pollack S. Effect of vitamin E supplementation on the regular treatment of seasonal allergic rhinitis.

Allergy 2003;58:1277-84. Vitamin E: Set The Record Straight Vitamin E does not thin the blood at recommended doses. Studies show anticoagulant effects occur at > 3,200 IU per day. Caution still taken with those on blood-thinners. Supplementing with high doses of vitamin E (> 400 IU/d) DOES NOT increase mortality. Recent study in Ann Intern Med had serious flaws. Most of the studies analyzed used synthetic vitamin E and many people in studies taking vitamin E had other serious comorbid conditions. Many other studies show benefit of taking supplemental vitamin E to prevent heart disease. Use natural vitamin E (d-alpha tocopherol) or mixed tocopherols, not synthetic (dl-alpha tocopherol). Omega-3 Fatty Acids Diet high in EPA decreased risk of developing hay fever in adults1. Children given 184 mg of fish oil per day from 6 months to 3 years old, in addition to dust mite control, had a 10% reduction in cough and a 7.2% decrease in dust mite sensitization2. Introduction of omega-3 fatty acids during pregnancy and early post-natal period may modulate immune system and decrease risk of developing allergies3. Some studies show benefit of fish oil in reducing severity and frequency of asthma. 1 Nagel G, Nieters A, Becker N, Linseisen J. The influence of the dietary intake of fatty acids and antioxidants on hay fever in adults. Allergy 2003;58:1277-84. 2 Peat JK, et al.

N-3 polyunsaturated fatty acids and allergic disease. Curr Opin Clin Nutr Metab Care 2004;7:123-9. Vitamin C Vitamin C has demonstrated in-vitro anti-histamine activity. Preliminary in-vivo studies found vitamin C helped reduce symptoms of hayfever1 2, but a controlled study found 2,000 mg per day of vitamin C had no benefit3. Few in-vivo trials were short-term (few days). May need to supplement with vitamin C for longer period of time to see benefits. May have other immune-modulating effects. Recommend 1,000-3,000 mg per day. Warn patients of loose stool (bowel tolerance). Unlikely at these doses. 1 Holmes HM, Alexander W. Hay fever and vitamin C. Science 1942;96:497. 2 Ruskin SL.

The effect of ascorbic acid on cutaneous and nasal response to histamine and allergen. J Allergy Clin Immunol 1982;69:484-8. Other Nutrients Vitamin B6: 100-200 mg per day. Vitamin B12: 1000 mcg oral daily or IM once per week. Vitamin D: 1200 IU per day with food. Selenium: 200 mcg per day with food. Vitamin B3 (niacinamide): 200 mg qid. IV Myers cocktail Thymus Extract Thymomodulin® is a special preparation of the thymus gland from calves. Studies show thymus extract helps improve symptoms of hay fever and allergic rhinitis1 2, food allergies3 4, and infection1. Has modulating effect on T-cells. 1 Kouttab NM, Prada M, Cazzola P.

Probiotics Beneficial bacteria part of normal flora of the gut, including Lactobacillus sp. and Bifidobacter sp. Probiotics improve digestion by limiting the absorption of food allergens and/or by changing immune responses to foods1 2. Probiotics may also be important in non-allergic food intolerances3. Not all probiotics are created equal! Lactobacillus GG one of the more reliable strains. One unpublished study found only 1 in 20 probiotic products contained exactly what was stated on the label. 1 Kirjavainen PV, Gibson GR.

May break large, allergenic proteins into smaller non-allergenic proteins. Bromelain and papain also useful. Preliminary research showed benefit in pancreatic enzymes as a treatment for food allergies1 2. Use of enteric coated pancreatic enzyme preparation reduced severity of food allergy symptoms in 10 patients (non-anaphylactic reactions)3. Potential benefits using betaine/HCl/pepsin for protein degradation, but no research supporting its use yet. 1 Oelgoetz AW, Oelgoetz PA, Wittenkind J.

Nettles Preliminary study showed that freeze-dried capsules of nettles (Urtica dioica) reduced sneezing and itching in those with hay fever1. Use 600-900 mg t.i.d. Nettles has a historical use in botanical medicine for treating cough, TB and arthritis. In-vitro studies suggest it may have anti-inflammatory effects and inhibit prostaglandins. 1 Mittman P. Randomized, double-blind study of freeze-dried Urtica dioica in the treatment of allergic rhinitis. Planta Med 1990;56:44-7. Butterbur (Petasites hybridus) Open label study with 580 patients with seasonal allergic rhinitis took 2 tablets a day of Butterbur extract Ze339 (containing 8 mg petasines per tablet) for two weeks. Symptoms of rhinorrhea, nasal congestion, itchy eyes and nose, red eyes and skin irritation improved in 90% of the patients compared with baseline.1 Use 50-75 mg bid. Is mild leukotriene inhibitor. Found to be as effective as 180 mg of fexofenadine.2 Butterbur contains pyrollizidine alkaloids, so should be used with caution or use PA-free extract. Butterbur is in the ragweed family so should be used with caution in those allergic to ragweed. 1 Kaufeler R, et al.

Yoga: many studies showing yoga can help reduce frequency and severity of asthma attacks. 2. Exercise: especially in overweight children. 3. Constitutional Hydrotherapy: can do home version with hit and cold towels. Easy for parents to do to their children. 4. TCM: Gua Sha: It involves palpation and cutaneous stimulation where the skin is pressured, in strokes, by a round-edged instrument, that results in the appearance of small red petechiae. Sublingual Immunotherapy (SLIT) Treatment concept same as injection; different route of administration. Allergy drops taken under tongue and then swallowed. Used in Europe more widely than in U.S. More than 30 years of clinical use. Proven safety record. No risk of anaphylaxis. Safe to use with children. Can use same diagnostic techniques to determine neutralizing dose (endpoint). More than 200 published clinical trials showing SLIT effective in treating inhalant and food allergies. Potential to treat other allergies/sensitivities (chemicals, autoimmune conditions)? SLIT: How Does It Work? Dendritic cells (DC) within the sublingual and buccal mucosa capture and process the antigen efficiently and are programmed to elicit IFN-γ and IL-10 which have a suppressive function in naïve CD4+ T-cells. DC also induce higher expression of toll-like receptors (TLR 2, 4,5,7) in other lymphoid tissues which have immunoregulatory effects. Mascarell L et al. Oral dendritic cells mediate antigen-specific tolerance by stimulating Th1 and regulatory CD4+ cells. J Allergy Clin Immunol 2008; Sep (133): 603-9. SLIT: How Does It Work? In vivo study with 10 children with house dust mite allergy treated for 12 months with SLIT showed a significant increase in IL-10, reduction of IL-12 and reduction of CD86 expression (necessary for T-cell proliferation and IL-2 production) in mature dendritic cells. Angelini F et al. Dendritic cells modification during sublingual immunotherapy in children with allergic symptoms to house dust mites. World J Pediatr 2011; Feb (7): 24-30. SLIT: How Does It Work? The sublingual mucosa contains a limited number of pro-inflammatory cells, such as mast cells. Therefore, there is little likelihood of having an adverse reaction when administering the drops under the tongue. Sublingual Immunotherapy The Research More than 50 RPCS and 5 meta-analyses show that SLIT is a safe, effective treatment for allergic rhinitis. There are more than 600 studies mentioned in the medical literature. Many of these studies also include asthma. The biggest factor determining clinical outcome is dose. Optimal dosing for SLIT has not been established and individual doses of allergen have varied tremendously, with a 30,000 fold difference in antigen dose ranging between 10 ng to over 300 mcg and differing dosing schedule from daily to a few times a week. Higher dosing regimens have generally been shown to be more effective. Sublingual Immunotherapy The Research Review of five meta-analyses, all involving children being treated for allergies to house dust mite, grass pollen and other various allergens showed a 32-95% improvement in symptoms of allergic rhinitis and a 33-76% reduction in use of allergy medications. Studies showed that the magnitude of SLIT therapy was higher in patients with more severe symptoms during grass pollen season (10%, 33% and 34% respectively) based on low, moderate and high severity symptom scores. No significant adverse effects with SLIT. Incorvaia C et al. The current role of sublingual immunotherapy in the treatment of allergic rhinitis in adults and children. J Asthma Allergy 2011;4:13-17. Sublingual Immunotherapy The Research Meta-analysis of nine studies including 232 children between the ages of 3 and 18 years old with mild to moderate allergic asthma compared with 209 controls. SLIT was initiated for allergies to dust mites, grass pollen and tree pollen for 6 to 32 months. Significant reductions is asthma symptom scores and use of rescue medication were observed on those receiving SLIT. Penagos M et al.

Sublingual Immunotherapy The Research 113 children aged 5 to 14 years old with allergic rhinoconjunctivitis limited to grass pollen were treated with either SLIT plus medication or medication alone for 3 years. No significant differences were observed in the first year of treatment, but in the the second and third years of treatment, there was a significant difference in hay fever symptom scores and use of medication. Development of asthma was 3.8 times higher in the control group than the SLIT treatment group. Novembre E et al. Coseasonal sublingual immunotherapy reduces the development of asthma in children with allergic rhinoconjunctivitis. J Allergy Clin Immunol 2004;114:851-7. Sublingual Immunotherapy The Research Review article using SLIT for treatment of Alternaria alternata, a common outdoor mold, found that children and adolescents treated with specific Alternaria IT had fewer respiratory symptoms and used less medication. No change in IgE was noted between treatment and control groups, but a significant increase in IgG4 was observed in the group receiving Alternaria IT. Is IgG4 a major player with mold allergy?

Allergol et Immunopathol Sublingual Immunotherapy The Research SLIT for the treatment of food allergies is relatively unknown as there are only a few studies (peanut and peach). One study treated 18 children with peanut allergy for 12 months (6 months of dose escalation and 6 months maintenance) using SLIT. The treatment group safely ingested 20 times more peanut protein than the control group and had a decrease in wheal size on skin prick testing. IgE levels initially increased and then decreased whereas IgG4 levels rose during the course of the treatment. Kim EH et al.

Sublingual Immunotherapy SLIT: Lasting Results Open controlled study of 59 adults with house dust mite allergy matched with 12 controls found that those receiving SLIT for 3 years, the clinical benefit lasted 7 years. In those who received SLIT for 4-5 years, the clinical benefit lasted 8 years. New sensitizations occurred in all control subjects and in less than a quarter of those receiving SLIT (21%, 12%, 11% respectively). Marogna M et al.

Sublingual Immunotherapy SLIT: High compliance and cost effective Meta-analysis of SLIT in children showed that compliance of therapy was very high (84%) and better than SCIT (61%). SLIT is significantly cheaper than SCIT. The average annual costs of SCIT in France was €2672 ($3900) before SLIT initiation and €629 ($918) after SLIT therapy. Marseglia GL et al. Sublingual immunotherapy in children: facts and needs. Italian Journal of Pediatrics 2009;35:31. Sublingual Immunotherapy What can be treated with SLIT? 1. Food allergies/sensitivities 2. Molds/Yeasts 3. Pollens (trees, grasses, weeds) 4. Dust and dust mites 5. Animal danders: cat, dog, horse, etc. Sublingual Immunotherapy Studies show SLIT is effective 75-90% of the time. The effectiveness of the treatment is based on quality of antigen, dose of antigen and duration of treatment. This is equal or superior to conventional injection immunotherapy. The duration of treatment can be short (6 months for food) up to many years (mold, pollens). Advantages of Sublingual Immunotherapy 1. Non-invasive. Drops are administered under the tongue or on the wrist. No needles or injections. 2. Excellent safety record. 3. No weekly doctor s visits to get treatment. Able to administer at home. 4. More control over dose. Treatment can be easily tailored to response. 5. More effective than conventional immunotherapy? Disadvantages of Sublingual Immunotherapy 1. Not covered by most insurance plans, despite its excellent safety record and cost effectiveness. No CPT code for SLIT. 2. Varying dosing regimens. Must be tailored to individual patient. 3. Works best with divided dosing schedule, often 3 times a day. With children, I recommend before school, after school and bedtime. Treatment Pearls 1. Alkalinize the body: sodium bicarbonate works well. 1/8-1/4 tsp bid-tid can help reduce allergy-like symptoms and wheezing. 2. Steam inhalation for wheezing with or without essential oils, such as eucalyptus, lavender or wintergreen oils. 1-2 drops in boiling water with head covered. Watch not to burn child. 3. Nasal irrigation daily. 4. Euphorbium homeopathic nasal spray for allergic rhinitis. 5. Homeopathic histaminum/luffa/euphorbium 30C for hayfever. 6. Nebulized glutathione: 60 mg/cc (2 cc ampules). Daily for one month for recurrent asthma. Contact Information Darin Ingels, ND 203-254-9957 (office) [email protected] Jessica Tran, ND 949-612-6371 [email protected]
