ABSTRACT

This study was aimed to determine the profiles of serum cytokines (IL-1ß, TNF-α, IL-4, IL-5) and chemokines (MCP-1: monocyte chemoattract protein-1 and RANTES: regulated on activation normal T cell expressed and secreted) in individuals with an asthmatic versus a non-asthmatic background with bacterial, viral or mixed acute respiratory infection. Asthmatic (n = 14) and non-asthmatic (n = 29) patients with acute viral, bacterial or mixed (bacterial and viruses) respiratory infection were studied. Patients were also analysed as individuals with pneumonia or bronchitis. Healthy individuals with similar age and sex (n = 10) were used as controls. Cytokine/chemokine content in serum was determined by ELISA. Increased cytokine/chemokine concentration in asthmatic and non-asthmatic patients was observed. However, higher concentrations of chemokines (MCP-1 and RANTES) in asthmatic patients infected by viruses, bacteria or bacteria and viruses (mixed) than in non-asthmatic patients were observed. In general, viral and mixed infections were better cytokine/chemokine inducers than bacterial infection. Cytokine/chemokine expression was similarly increased in both asthmatic and non-asthmatic patients with pneumonia or bronchitis, except that RANTES remained at normal levels in bronchitis. Circulating cytokine profiles induced by acute viral, bacterial or mixed lung infection were not related to asthmatic background, except for chemokines that were increased in asthmatic status.

ABSTRACT

Las infecciones respiratorias, uno de los síndromes más frecuentes a nivel comunitario pueden ser de dos tipos: infecciones del tracto respiratorio superior o inferior. En su gran mayoría son inicadas por una infección viral transformando el terreno vulnerable a la sobre infección bacteriana. Hasta 2/3 de los pacientes son tratados desde el inicio de los síntomas con antibióticos, aunque este tratamiento no influye positivamente sobre el curso de la enfermedad. Renikan, fitofármaco extraído de la raíz del Pelargonium Sidoides, posee un triple mecanismo de acción: antiviral, antibacteriano y mucolítico, antiviral, porque activa los mecanismos de defensa antivirales orgánicos, antibacetriano, por su actividad bacteriostática directa e indirecta, y mucolítico, por sus propiedades secretomotoras y expectorantes. El objetivo fue comprobar la efectividad y tolerabilidad de Renikan en el tratamiento de las infecciones respiratorias. Diseño abierto y multicéntrico. Se seleccionaron niños de 6 a12 años y adultos de cualquier sexo o raza, con infecciones del tracto respiratorio superior. A los cuales se le suministró Renikan durante 7 días continuos, se evaluó: evolución de los síntomas, necesidad de uso de antibióticos y la escala de resultados integraticos IMOs. Ingreason un total 305 pacientes, 156 adultos y 149 niños distribuidos en tres grupos de estudio: Rinosinusitis, 97 pacientes, los cuales presentaron mejoría de sus síntomas en un 86% en los adultos y no utilizaron antibióticos en un 86%; los niños mejoraron en un 80%, y no usaron antibióticos en 91%. En el caso de las Amigdalitis hubo 108 pacientes con una mejoría sintomatológica en adultos del 92% y en los niños el 89%, no antibióticoterapia en el 86% de los adultos y 93% de los niños. El uso de Renikan en pacientes con infecciones del tracto respiratorio superior, demuestra ser seguro y efecivo tanto en adultos como en niños mayores de 6 años


Respiratory tract infections are the most common syndromes at community, there are two types: upper and lower respiratory tract infections. The vast majoritary are stared by a viral infection transforming the land vulnerable into a bacterial infection. The 2/3 o patients is treated from the onset of symptoms with antibiotics, although it is known that this treatment not positively influences the course of the disease. Renikan, herbal extrated fron the root of pelargonium sidoides has a threefold mechanism of action: antibiotic and mucolytic, antiviral, because it activates the natural antiviral mechanism of defense; antibacterial, due to its direct and indirect bacterostatic action and mucolytic, owing to its secretomotory and expectorant properties. To test the effectiveness and tolerability of renikan in the treatment of respiratory infections. Open desing, multicenter study. We selected children 6-12 years'age and adults of any sex orrance with upper respiratory tract infecctions. Theyreceived renikan for 7 consecutive days, changes in symptoms; necessity of antibiotic use and the integrative medicine outcome scale (IMOS) were evaluated. Of total of 305 patients, 156 adults and 149 children were divided into three groups: 97 rhinosinusitis patients, who showed symptoms improvement in 86% of adults and 91% of children, in 108 tonsillitis patients, an improvement of symptoms was found in 92% of adults and 89% of children, no antibiotic use were in 86% of adults and 93% of children, and, in a third group consistng of 100 patients with bronchitis, improvement was report in 98% od adults and in 73% of children, no antibiotics were used in 88% of adults and 96% of children. The use of concomitant therapy decreasedin 50% of cases and only 0.02% of patients had adverse events. The use of renikan use in patients with upper respiratory tract infections was shown to be safe and effective in both adults and children over 6 years of age

ABSTRACT

In order to evaluate the respiratory health status in workers exposed to antigenic substances (chicken feathers, serum and dropping), typical of usual practice in the avian slaughter-house, pulmonary function was studied on 49 exposed workers, and in a sample of 49 people with similar anthropometric characteristics, non exposed to these substances, by means of occupational-medical history, spirometric tests, hematologic and biochemical tests, and postero-anterior chest x-rays. The values for the spirometric parameters varied with sex, age, weight, size, smoking habits, length of employment and exposure time, and there were no significant differences between exposed and control groups as a whole; showing significant differences with decreasing values for CVF, VEF1, PFE, FEF-25% and FEF-50% in the intermediate zone workers, and in subjects with short exposure time (< 1 year). Prevalence of clinical findings in the exposed population was significantly higher than the non exposed group (p < 0.001). Laboratory tests showed reduction of monocytes cells in the exposed group (p < 0.05) in addition, in the exposed women there was an increase of the eosinophiles, total proteins and globulines (p < 0.05). The frequency of radiographic findings was significantly higher in the exposed group (p < 0.006), and they were no specific. The lack of association between clinical findings, laboratory and radiographic findings, with the spirometric results, could be explained by the short period of exposure, individual and collectives hygienic conditions and size of the sample.
