The aim of this study was the evaluation of efficacy of the specific immunotherapy using Pollinex for 3 years before the period of pollen dust in children with seasonal allergic rhinitis and conjunctivitis induced by grass pollen. The study was carried out in a group of 40 children aged 5-18 years, from the Outpatient Department of Immunology at the National Research Institute of Mother and Child. The children demonstrated clinical symptoms of seasonal allergic rhinitis with conjunctivitis and had a medical history typical for this disease. Diagnostic procedures including skin prick tests and estimation of specific IgE to grass pollen by Pharmacia - CAP system, gave positive results. The efficacy of therapy was monitored by a clinical score with 4-0 points, recording symptoms relating to intensity of rhinoedema, rhinorrhea, sneezing, itching, oedema, conjunctival congestion, pain and lacrimation. In the study group, 39 children (97%) with seasonal rhinitis and conjunctivitis treated by specific immunotherapy (Pollinex) improved. This was confirmed by a statistically significant difference. The results indicate that the specific immunotherapy is an effective treatment of seasonal allergic rhinitis with conjunctivitis in children sensitized to grass pollen.

'Benifuuki', a tea (Camellia Sinensis L.) cultivar in Japan, is rich in anti-allergic epigallocatechin-3-O-(3-O-methyl) gallate (EGCG3''Me). 'Benifuuki' green tea and simultaneous addition of ginger extract remarkably suppressed cytokine (TNF-alpha and MIP-1alpha) secretion from mouse bone marrow-derived mast cells after antigen stimulation and, as expected, suppressed delay-type allergy. After drinking 'benifuuki' green tea containing 43.5 mg of EGCG and 8.5 mg of EGCG3''Me, the AUC (area under the drug concentration time curve; min mug/ml) of EGCG was 6.72 +/- 2.87 and EGCG3''Me was 8.48 +/- 2.54 in healthy human volunteers. Though the dose of EGCG was 5.1 times the dose of EGCG3''Me, the AUC of EGCG3''Me was higher than that of EGCG. A double blind clinical study on subjects with Japanese cedar pollinosis was carried out. At the 11th week after starting the study, in the most severe cedar pollen scattering period, symptoms, i.e., blowing the nose and itching eyes, were significantly relieved in the 'benifuuki' intake group compared with the placebo group, and blowing the nose, itching eyes and nasal symptom score, and at the 11th and 13th weeks, stuffy nose, throat pain and the nasal symptom medication score were significantly relieved in the 'benifuuki' containing ginger extract group compared with the placebo group. These results suggested that over one consecutive month, drinking 'benifuuki' green tea was useful to reduce some of the symptoms from Japanese cedar pollinosis, and did not affect any normal immune response in subjects with seasonal rhinitis, and the ginger extract enhanced the effect of 'benifuuki' green tea.

Childhood rhinitis may be classified into non-allergic and allergic. Allergic rhinitis is further divided into seasonal and perennial. Seasonal rhinitis is a disease particularly of teenagers and young adults and appears to be less common in primary and pre school age children. In seasonal rhinitis, with relevant grass pollen sensitization, the link between the allergen exposure and rhinitis is clear cut. However, in other situations such as perennial rhinitis and house dust mite allergen sensitization, the link between symptoms and allergen exposure is less certain. Avoidance of allergens often proves to be difficult in practice. Intranasal steroids are the treatment of choice for persistent moderate-severe allergic rhinitis and are more effective than antihistamines for relief of nasal obstruction. Antihistamines are effective for control of histamine related symptoms such as itching, rhinorrhoea and sneezing. The use and benefits of sublingual or injectable immunotherapy in children are controversial.

The literature documents the fact that UV irradiation of cutaneous Langerhans cells (LC) in vivo prevents the development of contact allergy and produces long-lasting immunosuppression. However, not much is known about the effect of UV irradiation on the LC of the nasal mucosa and their connection with clinical scores. Local antigen presentation may be necessary for both primary and recall T cell responses to birch pollen in patients with hay fever. Endonasal phototherapy combination of UVB (5%), UVA (25%) and visible light (70%) utilises the immunosuppressive effects of UV irradiation. The aim of this study was to correlate clinical symptom scores with possible changes in the LC of the nasal mucosa induced by UV radiation. The clinical effectiveness of this form of treatment is discussed. Nasal biopsies were obtained from ten birch pollen-sensitive patients with seasonal rhinitis before and after endonasal phototherapy. All patients showed a significant clinical benefit post-treatment as assessed by standardised instruments, including total nasal symptom score, nasal congestion score, nasal itching score, sneezing score, nasal secretion score and impairment-to-health score. However, we found no significant morphological changes, to, or quantitative differences in, the CD1a+, CD4, CD8 or CD31 cells before and 14 days after treatment. Despite the positive clinical effect, the study revealed no effect of UV irradiation on the LC and other analysed cells of the nasal mucosa immune system. Possible reasons for this are discussed.

Antihistamines play an important role in medicine when it comes to relieving seasonal or non-seasonal rhinitis, the common cold, and itching. They have also shown many various combinations of pharmacological properties such as anti-inflammatory and analgesic activities. Phenothiazines and ethylenediamines are 2 important classes of antihistamines with analgesic activities in addition to other pharmacological effects. In this study, some new derivatives of these compounds (V-IX) were synthesized and their antinociceptive behaviors were examined by pharmacological tests. The results indicated that new analogue with methyl groups produced a better analgesic activity than chlorine atoms but less than III (without any substitutions) in ethylenediamine class. Also in phenothiazine class, adding pyrimidine and pyridine substituted showed the better analgesic activity compared to other groups. Moreover, the analgesic activities proved that dimethylamine is the best group in amino alkyl side chain of these molecules relative to the substituted piperazines in new analogues.
