Homeopathic medicines for prevention of influenza and acute respiratory tract infections in children: blind, randomized, placebo-controlled clinical trial.

BACKGROUND: Influenza and its complications are common at all ages, especially in children. Vaccines and anti-influenza drugs aim to prevent it. Preventative approaches with favorable risk profiles should be considered for flu, particularly since the evidence of the efficacy of anti-viral drugs is debated. METHODS: This pragmatic clinical trial was conducted in the Brazilian Public Health System in Petrópolis (BPHSP) with children aged from 1 to 5 years old. The medications used were mainly selected based on in vitro experiments (InfluBio), and in successful qualitative clinical experiences (Homeopathic Complex). Following informed parental consent, subjects were randomly distributed, in a blind manner, to three experimental groups: Homeopathic Complex, Placebo, and InfluBio. BPHSP health agents collected flu and acute respiratory infection symptomatic episodes monthly following the established protocol. The number of these episodes was registered in one year (2009-2010). RESULTS: Out of the 600 children recruited, 445 (74.17%) completed the study (149: Homeopathic complex; 151: Placebo; 145: InfluBio). The number of flu and acute respiratory infection symptomatic episodes detected in this clinical trial was low; however, it was different between homeopathic groups and placebo (p < 0.001). In the first year post-intervention, 46/151 (30.5%) of children in the placebo group developed 3 or more flu and acute respiratory infection episodes, while there was no episode in the group of 149 children who used Homeopathic Complex, and only 1 episode in the group of 145 (1%) children who received InfluBio. CONCLUSION: These results suggested that the use of homeopathic medicines minimized the number of flu and acute respiratory infection symptomatic episodes in children, signalizing that the homeopathic prophylactic potential should be investigated in further studies.

O uso da homeopatia para prevenir sintomas da gripe humana e infecção respiratória aguda: um estudo clínico duplo cego, randomizado, placebo controlado com 600 crianças do Serviço Público de Sáude do Brasil / The use of homeopathy to prevent symptoms of human flu and acute respiratory infections: a double-blind, randomized, placebo-controlled clinical trial with 600 children from Brazilian Public Health Service

In Brazil, homeopathy was implemented in the Public Health Service through the National Policy on Complementary and Integrative Practices of the Health Ministry, published in 2006. Homeopathy appears as a very interesting therapy to be used in the Public Health Services since its medicines are compounded at a very low cost. Considering this interesting scenario to develop research in the Public Health, the Family Health Program (FHP) in Petropolis and the Faculty of Pharmacy at UFRJ started a partnership with the Roberto Costa Institute.(AU)

No Brasil, a homeopatia foi implementada no Serviço Público de Saúde, através da Política Nacional de Práticas Integrativas e Complementares do Ministério da Saúde, publicada em 2006. A homeopatia surge como uma terapia muito interessante para ser usada no serviço público de saúde uma vez que seus medicamentos tem um custo muito baixo. Considerando este cenário interessante para desenvolver uma pesquisa em Saúde Pública, o Programa de Saúde da Família (PSF) de Petrópolis e a Faculdade de Farmácia da UFRJ iniciaram uma parceria com o Instituto Roberto Costa.

Cell alterations induced by a biotherapic for influenza / Cell alterations induced by a biotherapic for influenza

Introduction: Influenza viruses have been responsible for highly contagious acute respiratory illnesses with high mortality, mainly in the elderly, which encourages the development of new drugs for the treatment of human flu. The biotherapics are medicines prepared from biological products, which are not chemically defined. They are compounded following the homeopathic procedures indicated for infectious diseases with known etiology [1]. Aim: The purpose of the present study is to verify cellular alterations induced by a biotherapic prepared from the infectious influenza A virus. Methodology: This biotherapic was prepared for this study in the homeopathic potency of 30X according to the Brazilian Homeopathic Pharmacopeia [2]. The concentration of 10% was not cytotoxic to cells, as verified by neutral red assay. The cellular alterations observed in MDCK cells were analyzed by optical microscopy for the quantification of mitosis, nucleoli and lipid bodies. The mitochondrial activity was assessed by MTT assay and the phosphosfructokinase-1 (PFK-1) enzyme activity was analyzed on the MDCK cells treated for 5, 10 and 30 days. Macrophages J778.G8 were treated with this biotherapic to evaluate the immunostimulatory cytokine release. Results: The cellular alterations observed in MDCK cells were verified by optical microscopy. The number of lipid bodies present in MDCK cells stimulated for 10 days was significantly lower (p <0.05) when compared to controls. The biotherapic significantly increased (p <0.05) the number of mitosis and the mitochondrial activity of MDCK cells stimulated for 10 and 30 days. These changes were confirmed by a significant reduction (p <0.05) on the PFK-1 activity. These results suggest that the biotherapic was able to activate the Krebs cycle and pentosephosphate metabolism to the generation of amino acids and nucleotides, situations common to cells whose rate of mitosis is increased. The quantification of immunostimulatory cytokines by macrophages J774.G8 indicated that the tumor necrosis factor (TNF-?) production was higher (p <0.05) in the supernatant of the macrophages pre-treated with this biotherapic and infected with influenza virus, suggesting an activation of the macrophages by this biotherapic. Conclusion: This biotherapic is able to induce some cellular alterations, which show strong evidence that it might be a promising option for the human flu. New experiments are being developed to understand the mechanisms of action of this biotherapic.(AU)
