Background: Allergic diseases are among the most common diseases in humans. Besides allergen avoidance, allergen-specific immunotherapy is the only causative treatment option. During recent years, many innovations of this therapy have emerged. Methods: Selective literature research in Medline and PubMed, under the inclusion of national and international guidelines and Cochrane meta analyses. Results: In several meta-analyses, the clinical efficacy of subcutaneous immunotherapy (SCIT) has been largely demonstrated. Recently, major research activities in mucosal immunotherapies focused on the sublingual application route. There are well-documented clinical data on the efficacy and safety of this form of immunotherapy. New application routes as well as new immune-modifying agents such as virus-like particles or CpG-motifs have also been investigated. Conclusion: SIT is accepted to be the only causative treatment option for allergies. New application routes and new immune-modifying agents will allow for different delivery methods in the future.  相似文献

Submicroscopic changes in adrenocorticocytes and sinusoidal capillaries were studied in experiments on sexually mature male guinea pigs on the 1st–2nd, 7th, 14th, 21st, and 28th days after burns. During the first week the hormone-forming cells of the gland were dominated by hyperplasia, which took place against the background of functionally excited sinusoids. On the 14th day, besides hyperplasia and hypertrophy, destruction of organelles was considerably increased in parenchymatous and endothelial cells. Increasing disorganization and death of membranous components of the cells led to a subsequent sharp disturbance of vaso-parenchymatous relations and to the development of profound dystrophic changes and necrobiotic lesions of the adrenal cortex.Department of Histology and Embryology, Ternopol' Medical Institute.

IgE-mediated food allergy remains a significant and growing problem across the globe. Of the various treatment modalities, oral immunotherapy (OIT) and epicutaneous immunotherapy (EPIT) have been the best studied. Across various studies of OIT for egg, milk, and peanut allergy, strong levels of desensitization have been shown. With egg and peanut OIT, a limited remission, or sustained unresponsiveness (SU), has further been demonstrated. These advances have been further validated by successful phase 2 and phase 3 studies of peanut OIT. EPIT, using daily administrations of a proprietary patch, demonstrated efficacy as well as safety and tolerability in parallel phase 2 studies; however, its phase 3 study did not meet its primary efficacy outcome. Despite its good track record of desensitization, the safety and tolerability of OIT has remained a question. EPIT, on the other hand, has proven safe and tolerable; however, the adequacy of its desensitization has remained to be determined. As OIT and EPIT continue their march toward regulatory review, optimizations for immunotherapy and novel therapies continue to be developed providing hope for food allergy patients everywhere.  相似文献

It was shown by intravital microscopy that oxidoreductases can be demonstrated histochemically and changes in their activity studied in the intramural nervous plexuses of the small intestine in the living animal. Severe thermal injury was shown to disturb the permeability of the mitochondrial membranes of the nerve cells of Auerbach's plexus in animals, as a result of which the activity of the oxidoreductases located inside the mitochondria is modified. Lumbar procaine block, carried out immediately after burning, was shown to restore the normal state of the mitochondrial membranes of the nerve cells.A. V.

In 44 patients highly sensitive to ragweed, we compared weekly injections of single doses of ragweed extract (RW-Wk, 15 patients) with clustered doses of ragweed extract at 3-wk intervals (RW-Cl, 18 patients) and with placebo (11 patients) for effects on ragweed hay fever symptom-medication scores and immunologic variates. Patients were matched and randomly assigned to treatment groups. Ragweed doses were advanced to the highest tolerated dose. Doses and number of visits were lower in the RW-Cl group than in the RW-Wk group. Despite lower doses, systemic reactions were not reduced and antiragweed IgE levels increased significantly more in the RW-Cl group than those in the RW-Wk group. Both the RW-Cl and RW-Wk groups had significant increases in antiragweed IgG levels, decreases in seasonal rise in antiragweed IgE levels, and lower symptom-medication scores (p < 0.01) in comparison with the placebo group. We conclude that the RW-Cl regimen offered no important advantage over RW-Wk. Seventeen patients had previously received Rinkel-method immunotherapy with 0.5 ml of end-point dilution of ragweed extract for 1 to 2 yr without significant clinical improvement or immunologic changes. After adequate treatment with either RW-Wk or RW-Cl, these patients had significantly lower symptom-medication scores than those of the placebo group and immunologic changes similar to those of the entire active-treatment group. Therefore, treatment failures on Rinkel immunotherapy respond well to adequate dose immunotherapy by either schedule.  相似文献

The intensity of glycolytic oxidoreduction in the rat liver was investigated 3, 6, 12, and 24 days after the production of an experimental burn. Burns were shown to depress glyceraldehyde phosphate dehydrogenase activity and to reduce the formation of 3-phosphoglyceric acid in the liver of the animals, the effect being most marked during the period of burn trauma (6th day). The factor limiting the course of this reaction after burns is NAD deficiency in the cell. Disturbance of the course of this reaction is one of the causes of the decrease in intensity of the whole glycolytic pathway of carbohydrate breakdown and the decrease in the energy-supplying role of glucose in burns.Department of Biochemistry, Ivanovo Medical Institute.

Allergen-specific immunotherapy (SIT) defines and distinguishes the modern practice of clinical allergy and immunology as the 100th anniversary of this pioneering technique is celebrated. Despite the tremendous advancements made in therapeutics, pharmacology, and the basic science of allergy, SIT remains the only treatment modality that offers a potential cure for atopic diseases rather than simply an amelioration of symptoms. A historical perspective not only offers an opportunity to tell some of the fascinating stories that led to the conception of SIT but also gives an occasion to recognize, remember, and honor those individuals who have contributed to its development.  相似文献
