Effect of multiple honey doses on non-specific acute cough in children. An open randomised study and literature review

BACKGROUND: Honey is recommended for non-specific acute paediatric cough by the Australian guidelines. Current available randomised clinical trials evaluated the effects of a single evening dose of honey, but multiple doses outcomes have never been studied. OBJECTIVES: To evaluate the effects of wildflower honey, given for three subsequent evenings, on non-specific acute paediatric cough, compared to dextromethorphan (DM) and levodropropizine (LDP), which are the most prescribed over-the-counter (OTC) antitussives in Italy. METHODS: 134 children suffering from non-specific acute cough were randomised to receive for three subsequent evenings a mixture of milk (90 ml) and wildflower honey (10 ml) or a dose of DM or LDP adjusted for the specific age. The effectiveness was evaluated by a cough questionnaire answered by parents. Primary end-point efficacy was therapeutic success. The latter was defined as a decrease in cough questionnaire score greater than 50% after treatment compared with baseline values. RESULTS: Three children were excluded from the study, as their parents did not complete the questionnaire. Therapeutic success was achieved by 80% in the honey and milk group and 87% in OTC medication group (p = 0.25). CONCLUSIONS: Milk and honey mixture seems to be at least as effective as DM or LDP in non-specific acute cough in children. These results are in line with previous studies, which reported the health effects of honey on paediatric cough, even if placebo effect cannot be totally excluded

Impact of excess weight and estrogen receptor gene polymorphisms on clinical course of homozygous beta thalassemia.

In homozygous beta thalassemic patients we examined the role played by the interaction of ER gene polymorphisms with adverse environmental factors. A total of 108 homozygous beta thalassemic patients, 60 prepubertal mean age 9,5 +/- 3,7 years (27 M, 33 F) and 48 pubertal mean age 22,2 +/- 5,4 years (21 M, 27 F), regularly treated with red cell transfusion and iron chelation therapy were segregated on the basis of their XbaI and PvuII ER gene polymorphisms. Body mass index (BMI), lipidic pattern and blood pressure values were evaluated in each group. No significant differences were observed between patients segregated by their PvuII ER genotypes. Prepubertal and pubertal patients of both sexes lacking XbaI site showed BMI, HDL, LDL cholesterol significantly different than the other patients. In addition, triglyceride levels and blood pressure values were significantly higher in pubertal patients of both sexes lacking XbaI site than in other patients. ER XbaI polymorphism appear to influence nutritional factors, metabolic status and blood pressure and could be considered additional risk factors for later cardiac involvement in beta thalassemic patients.
