Allergen-specific immunotherapy (AIT), although in clinical use for more than a century, is still the only causal treatment of allergic diseases. The safety and efficacy of AIT has been demonstrated in a large number of clinical trials. In addition to allergy symptom reduction AIT plays an essential role in preventing new allergies and asthma and shows long-term effects after discontinuation of treatment. Ideally, it is capable of curing allergy. However, AIT is not effective in all allergic individuals and is not equally effective in the treatment of various hypersensitivities to different allergens. For many years, the route of administration and the vaccine compositions have been evolving. Still there is a strong need for research in the field of new AIT modalities to increase its effectiveness and safety. Growing evidence on immunological effects of AIT, especially new T cell subsets involved in antigen/allergen tolerance, provides novel concepts for safer and more effective vaccination. Pharmacoeconomic studies have demonstrated a clear advantage of AIT over pharmacologic therapies.

The prognosis of patients with malignant brain tumors has improved only slightly despite the combined use of surgery, radiation therapy, and chemotherapy. Immunotherapy offers some possibilities and hopes as a fourth modality for the treatment of cancers although it is still in the early stages of development. It is possible to classify immunotherapy within four generally accepted modalities : 1) restorative or nonspecific immunotherapy 2) adoptive immunotherapy 3) passive immunotherapy 4) active immunotherapy. The techniques of recombinant DNA, genetic engineering, cell fusion and hybridoma production, and molecular biology will make these therapeutic approaches more successful and as the clinical applications expand the skillful cancertherapist will become increasingly familiar with these treatments and the problems associated with their use.

Booster immunization is the following vaccination after a period of vaccine primary immunization schedule in order to maintain immunity against a certain pathogen. In this article, the immunological mechanism of booster immunization is elaborated, and the effectiveness and public health value of booster immunization for common vaccines is discussed. Subsequently, three hot issues of general concern in booster immunization are addressed, and the public health viewpoint that "Primary immunization of vaccines is fundamental, and booster immunization is the guarantee" is emphasized, so as to raise awareness of the importance and necessity of booster immunization as well as to provide scientific evidences for vaccine immunization practice.

We reported a successful oral immunotherapy (OIT) in 2 children with high wheat sensitivity (4 and 14 years old boys). Oral challenges indicated eliciting doses of 300 mg, and wheat flour of 30 mg. The OIT protocol includes 5 days of build-up phase in the hospital, intervening with 2 to 5 months of home maintenance phase. Patients could tolerate 45 g, and 60 g of wheat flour per day, respectively. We have demonstrated that OIT to a large amount of wheat in extremely sensitized patients could be achieved with a stepwise multi oral/maintenance regimen.

Allergen specific immunotherapy is a medical treatment aiming at patients suffering from allergies that are insufficiently controlled by symptomatic treatments. Allergen immunotherapy rehabilitates the immune system. Subcutaneous immunotherapy (SCIT) is the historical route of administration and consists of allergen extract injections. SCIT has proven efficacy in allergic rhinitis and asthma, but it requires regular injections at the hospital and carries the risk of potentially serious systemic allergic reactions in response to the treatment itself. Sublingual immunotherapy (SLIT) offers several specific advantages over SCIT. SLIT is more easily administered, avoids cumbersome injections regimens, and carries a much lower risk of anaphylactic shock compared with SCIT. So, this article will discuss the mechanisms of action, advantages, and limitations of SLIT for allergic rhinitis.

Even though atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases, its treatment remains a challenge in clinical practice, with most approaches limited to symptomatic, unspecific anti-inflammatory, or immunosuppressive treatments. Many studies have shown AD to have multiple causes that activate complex immunological and inflammatory pathways. However, aeroallergens, and especially the house dust mite (HDM), play a relevant role in the elicitation or exacerbation of eczematous lesions in many AD patients. Accordingly, allergen-specific immunotherapy has been used in AD patients with the aim of redirecting inappropriate immune responses. Here, we report three cases of refractory AD sensitized to HDM who were treated with sublingual immunotherapy.
