Opis:
Introduction. Numerous publications indicate that the prevalence of some infectious, neoplastic and immunological diseases are associated with ABO blood groups. Objective. The aim of this study was to verify whether ABO and Rh blood groups are associated with severe anaphylactic reactions after Hymenoptera stings. Materials and Method. A study was undertaken of 71,441 Caucasian subjects living in the same geographic area. The study group included 353 patients with diagnosed systemic anaphylaxis to Hymenoptera venom. Control group included 71,088 healthy blood donors. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. Results. No statistically significant interactions were observed between the ABO blood group and anaphylactic reactions to Hymenoptera.

Opis:
ObjectivesVenom immunotherapy (VIT) is an effective treatment method and is addressed to patients with a history of an anaphylactic reaction to Hymenoptera stings. However, the immunological mechanisms of protection have not been explained yet. The objective of this study was to analyze neutrophils, interleukin 8 (IL-8) and interleukin 17 (IL-17) before and after the initial phase of the immunotherapy.Material and MethodsOverall, 40 individuals, including 20 wasp venom sensitized and 20 bee venom sensitized patients, were included in the study. The patients had had a history of severe allergic reactions type III and IV according to Mueller’s classification. An ultra-rush VIT protocol was used in this study. The concentration of serum IL-8 and IL-17A was determined using the ELISA enzymatic method.ResultsThe authors demonstrated a significant rise in the IL-8 level after the immunotherapy, compared to baseline (14.9 vs. 24.7, p < 0.05). The rise in the neutrophils level was also noticeable but proved to be barely out of the range of statistical significance (4.3 vs. 5.0, p = 0.06). The shift in IL-17A was negligent and not statistically significant in the paired samples t-test (1.6 vs. 1.5, p = 0.34)ConclusionsVenom immunotherapy induces neutrophils and IL-8 activity after 2 days. After the desensitization, the level of IL-17A did not change.

Opis:
Objectives: The aim of the study was to verify whether simultaneous responses from the muscular and circulatory system occur in the driver's body under simulated conditions of a crash threat. Materials and Methods: The study was carried out in a passenger car driving simulator. The crash was included in the driving test scenario developed in an urban setting. In the group of 22 young male subjects, two physiological signals - ECG and EMG were continuously recorded. The length of the RR interval in the ECG signal was assessed. A HRV analysis was performed in the time and frequency domains for 1-minute record segments at rest (seated position), during undisturbed driving as well as during and several minutes after the crash. For the left and right side muscles: m. trapezius (TR) and m. flexor digitorum superficialis (FDS), the EMG signal amplitude was determined. The percentage of maximal voluntary contraction (MVC) was compared during driving and during the crash. Results: As for the ECG signal, it was found that in most of the drivers changes occurred in the parameter values reflecting HRV in the time domain. Significant changes were noted in the mean length of RR intervals (mRR). As for the EMG signal, the changes in the amplitude concerned the signal recorded from the FDS muscle. The changes in ECG and EMG were simultaneous in half of the cases. Conclusion: Such parameters as mRR (ECG signal) and FDS-L amplitude (EMG signal) were the responses to accident risk. Under simulated conditions, responses from the circulatory and musculoskeletal systems are not always simultaneous. The results indicate that a more complete driver's response to a crash in road traffic is obtained based on parallel recording of two physiological signals (ECG and EMG).
