Menendez S, Iglesias O, Bidot C, Puga R, Carballo. Application of ozone therapy in children with humoral immunity deficiency. From the National Center for Scientific Research, Ozone Research Center, P.O. Box 6880, Havana, Cuba. Abstract: Some bacteria and toxins are not phagocytized by the reticuloendothelial cells, but instead must be destroyed in some other way. Fortunately, the body has still another line of defense called immunity. The blood and other body fluids contain special proteins called antibodies, that react chemically with the invading organisms or toxins to destroy them. Antibodies are gamma globulins, called immunoglobulins and represent 20% of all the plasmatic proteins. It has recently been demonstrated the stimulating effects of ozone in the immune system and also its immunomodulatory properties, according to doses. The aim of this research was to evaluate the effects, that ozone therapy exerts, in different immunoglobulins (IgA, IgG and IgM) of children with humoral immunity deficiency. 61 out-patients, between 1 and 5 years, with humoral immunity deficiency (98% with IgA deficiency) were studied. Those children suffered, frequently head cold, tonsillitis, adenoiditis, otitis, asthma and pneumonia. Ozone was applied (5 days a week) by rectal insufflation, at age dependent doses, during 3 weeks. During treatment, no other medication was used. Different immunoglobulins (IgA, IgG and IgM) were measured at the beginning and at the end of treatment. For the statistical significances, Wilcoxon Sum Rank Test was applied. Increases in IgA and IgG values, with high statistical significant differences (p<10(-4)), were achieved. Also IgM values increased, with statistical significant differences (p<0.05). IgA, IgG and IgM initial and final mean values are shown in table 1. Table 1 IgA, IgG and IgM MEAN VALUES AT THE BEGINNING AND END OF TREATMENT ---------------------------------------------------------------- Immunoglobulins Initial Mean Value Final Mean Value P ---------------------------------------------------------------- IgA 0.55 p/m 0.01 1.66 p/m 0.07 <10(-4) IgG 8.10 p/m 0.29 14.89 p/m 0.61 <10(-4) IgM 0.96 p/m 0.06 1.81 p/m 0.07 <0.05 ---------------------------------------------------------------- In all patients, humoral immunity was normalized, taking into account the different immunoglobulins values according to age. In all patients, clinical improvements were also achieved. 6 months after finishing the treatment, no relapse was found and all the children increased, in weight and size, in more than 50% percentile. Ozone therapy, by rectal insufflation was well tolerated, and no side effects were achieved.
