ABSTRACT

Psoriasis is one of the most common, chronic skin diseases of as yet unexplained etiopathogenesis. In the recent years it has been proven that an immunological factor plays an important role in the dermatosis onset. This has led to introduction of biological drugs to the disease treatment regimen, which include, inter alia, adalimumab and ustekinumab. New therapy has become an alternative for patients with psoriasis resistant to standard treatment methods as well as an alternative form of treatment in case of occurrence of severe adverse drug reactions after administration of standard treatment. Despite good treatment results the administration of these drugs is associated with the occurrence of adverse reactions. This article presents cases of 4 patients who have been administered biological treatment and in whom there have been observed, inter alia, the occurrence of hypersensitivity reactions in the form of acute urticaria as well as skin lesions of erythema multiforme nature or positive antinuclear antibodies titre. The symptoms experienced by the presented patients posed no direct threat to life and the benefits of the drugs' administration had a significant therapeutic importance.

ABSTRACT

INTRODUCTION: Different endotypes of rhinitis are known, but its pathomechanism has not been conclusively established. For example, the precise difference between systemic allergic rhinitis (SAR) and local allergic rhinitis (LAR) is still being checked. Comparison of patients with LAR and with allergies to birch of those with intermittent allergic rhinitis, same allergy, or with non-allergic rhinitis (NAR) was the purpose of this study. METHODS: Twenty-six patients with LAR, 18 with SAR and allergy to birch, and 21 with NAR were included. Patients who met the inclusion criteria were selected to undergo the following procedures at baseline: medical examinations, nasal provocation test (NPT), detection of nasal-specific IgE to birch as well as basophil activation test (BAT). All immunological parameters were detected before and after NPT. RESULTS: Concentration of nasal IgE to Bet v1 increased comparably in the LAR and SAR groups after NPT to birch as follows: in 21 (81%) patients with LAR, 14 (78%) with SAR, and in everyone in the NAR group. Serum concentration of allergen-specific IgE to Bet v1 increased significantly from a median of 20.7 (25-75% interval: 11.2-35.6) IU/mL to 29.9 (13.6-44.1) (p = 0.028) after NPT in patients with SAR. Allergen-specific IgE to Bet v1 was absent in all patients with LAR and NAR before and after NPT. BAT with Bet v1 was positive in 22 (85%) patients with LAR, in 14 (78%) with SAR, and 2 (9.5%) with NAR. CONCLUSION: These obtained data suggest there are no potential mechanisms that could explain LAR compared to SAR.

ABSTRACT

Background: The effect of prolonged allergen immunotherapy is still insufficiently known, especially in elderly patients. Objective: The effect after a 3-year course of injected allergen-specific immunotherapy (AIT) for grass pollen allergy in elderly patients with allergic rhinitis was observed. Methods: Thirty-eight elderly patients (mean ± standard deviation, 66.2 ± 2.7 years old) who received preseasonal injected AIT or placebo for grass pollen allergy were monitored for 3 years and compared with a placebo group. The combined symptom medication score (CSMS), serum level of immunoglobulin G4 (IgG4) to phleum pratense 5 (Phl p5) and quality of life were assessed immediately after AIT and 3 years later. Results: After AIT, the CSMS was significantly decreased from 2.15 (range, 1.27-3.00) to 1.13 (range, 0.79-1.36) (p = 0.03) and remained lower (1.41 ± 0.72 versus 2.41 ± 1.11) than that in the placebo group during the 3 years after AIT. Serum-specific IgG4 against increased during the course of AIT and remained at a high level during further observation. Quality of life, based on the Rhinoconjunctivitis Quality of Life Questionnaire, was significantly decreased in the patients who received AIT from 1.51 (95% confidence interval [CI], 1.21-1.84) to 1.01 (95% CI, 0.93-1.87) (p < 0.05) and was decreased to 0.97-1.26 (95% CI, 0.88-1.82) during the 3 years after discontinuation of AIT. Conclusion: A prolonged positive effect after AIT for grass pollen allergy was observed in elderly patients with allergic rhinitis. Further trials are needed to confirm this effect.Clinical trial MC56871/12, www.clinicaltrials.gov.
