We assessed the long-term persistence of humoral immunity against diphtheria in adults with childhood vaccination and the immunogenicity of a booster dose considering demographic, behavioural and vaccinating factors. We conducted a trial in 200 healthy Slovak adults aged 24–65 years, immunised against diphtheria in childhood and against tetanus at regular 10–15 year intervals, and receiving a dose of a tetanus-diphtheria toxoid vaccine. The response was determined by ELISA antibody concentrations of paired sera before and at 4 weeks post-vaccination. A seroprotection rate of 21% (95% confidence interval, CI 15.6–27.3%) was found in adults up to 59 years since the last vaccination with seroprotective levels of antibodies against diphtheria ≥0.1 IU/mL and a geometric mean concentration of 0.05 IU/mL. Conversely, seropositive levels ≥0.01 IU/mL were observed in 98% of adults (95% CI 95–99.5%). Booster-induced seroprotection was achieved in 78% of adults (95% CI 71.6–83.5%) clearly depending on pre-booster antibody levels correlating with age and time since the last vaccination. Moreover, only 54.2% of smokers and 53.3% of patients on statins exhibited seroprotection. Booster vaccination against diphtheria was unable to confer seroprotection in all recipients of only childhood vaccination.
Introduction: Intervention of pharmacists in medication adherence can meaningfully contribute to achieving therapeutic outcomes. Exploring the real-life readiness and opportunities of pharmacists may result in the adoption of measures, which could be seen through improvement of patients’ adherence to pharmacotherapy.
Aim: The aim of the paper was to make a survey on community pharmacists’ potential in medication adherence support in its connectivity to technical and personnel factors, which underline the capacities of pharmacies in dealing with medication adherence.
Methods: The questionnaire survey was conducted from October to December 2014 and involved 158 pharmacists from 117 Czech (CZ) and 41 Slovak (SK) community pharmacies. The structured questionnaire surveyed both technical and personnel factors, including provision of consultancy services related to medication adherence. Non-adherence risk reduction was evaluated by adopting Morisky Scale modified from the pharmacist’s perspective. Questionnaires outcomes were summarised in contingency tables and analyzed for associations between respective categorical variables using χ2 or exact tests and association coefficients. All results are reported as significant at P≤0.05.
Results: The average score of adherence support (CZ/SK 1.95/1.93) was significantly higher as compared to that of persistence or concordance (P<0.001). Reduction of non-adherence risk reached the score of a medium degree (P=0.73, average 2.29 in CZ and 2.22 in SK). These findings were significantly associated with personnel capacities (provision of consultancy, preference for the use of recommended procedures in CZ (P<0.001), number of years of practice in SK (P=0.029)), while significant association with technical equipment (consultancy room) in the SK (P=0.037).
Conclusion: The pharmaceutical care is developing towards the improvement of medication adherence in both countries - assuming a medium degree of adherence support. Further progress may be observed in strengthening the pharmacists’ personnel capacities, and accelerated mainly using information technologies, i.e. through technical capacities.
Objective
This experimental study evaluated the anti-asthmatic capacity of the dihydroxyflavone chrysin in the settings of ovalbumin (OVA)-induced allergic inflammation.
Methods
The parameters that were used to assess the anti-asthmatic activity of chrysin included the specific airway resistance to histamine, the sensitivity to a chemically induced cough and the activity of chrysin on the ciliary beat frequency (CBF) of the respiratory epithelium. The anti-inflammatory potential was confirmed by the measurement of cytokine concentrations Th2 (IL-4, IL-5 and IL-13), Th1 (Granulocyte-macrophage colony-stimulating factor [GM-CSF], INF-γ and IL-12), leucocyte count in the bronchoalveolar lavage fluid (BALF) and growth factor TBF-β1 in lung homogenate.
Key findings
Chronic administration of chrysin (30 mg/kg/day for 21 days) to OVA-sensitised guinea pigs showed bronchodilatory activity comparable to that of long-acting β 2 receptors agonist (LABA) salmeterol. Chrysin revealed antitussive efficiency but was not able to abolish the negative effect of OVA on CBF. Chrysin managed to ameliorate the progression of chronic airway inflammation by decreasing the count of eosinophils, lymphocytes and basophils, IL-5, L-13, GM-CSF, INF-γ in BALF, and TGF-β1 in lung homogenate.
Conclusions
The acquired results support the complex anti-asthmatic profile of chrysin. The flavone may represent an attractive compound for further studies concerning the prevention or treatment of asthma.
