ABSTRACT

El objetivo del estudio es comprobar si el tabaco altera la relación entre PCR y los valores de triglicéridos, colesterol total y sus fracciones, en una población fumadora sana. Material y método. Se realiza un estudio observacional transversal en 800 sujetos sanos, 200 fumadores y 344 no fumadores y 256 exfumadores. Para la determinación de la PCR se utilizó el test Tina-quanta CRP (Látex) HS. Resultados. La concentración de PCR fue mayor en los fumadores que en los no fumadores (p<0,01). La concentración de triglicéridos fue mayor en los fumadores que en los no fumadores (p<0,001), así como la cifra de LDL-c (P<0,05). No se encontraron diferencias significativas en el colesterol total entre ambos grupos. La fracción HDL-c se encontraba disminuida en los fumadores con respecto a los no fumadores (p<0,001). Existe una correlación positiva, tanto en fumadores como en no fumadores, entre PCR y cifras de triglicéridos (p<0,001), y negativa con HDL-c (p<0,001). No se encontró una asociación lineal entre la PCR y el colesterol total, ni entre la PCR y el LDL-c en no fumadores. La PCR se encuentra asociada estadísticamente con la LDL en los fumadores (p<0,001). Conclusiones. Las concentraciones séricas de PCR, triglicéridos y LDL-c se encuentran más elevadas en los fumadores que en los no fumadores sanos. Los niveles de HDL son más bajos en la población fumadora sana. Los niveles de PCR aumentan al incrementarse los triglicéridos y tienen una relación inversa con los niveles de HDL-c en ambas poblaciones. Los niveles de PCR y LDL-c se encuentran asociados estadísticamente sólo en la población fumadora (AU)


The aim of this study is to verify whether cigarette smoking alters the relation between C-reactive protein (CRP) and triglycerides, HDL and LDL-cholesterol plasma concentration in a healthy population. Population and methods. This is a cross sectional study conducted in a sample of 800 collective healthy aircraft workers, 200 smokers, 344 non-smokers and 254 exsmokers. They all undertook a complete annual clinical, psychological and analytical examination. C-reactive protein was determined by test Tina-quanta CRP (Látex) HS. Results. Serum CRP concentration was significantly higher in smokers than in non-smokers (p<0,01). Serum concentration of triglycerides and LDL levels were higher in smokers (p<0,01), as well as LDL levels (p<0,05). No statistically differences in total cholesterol levels between smokers and non-smokers were found. HDL fraction was lower in smokers compared to non smokers (p<0,01). CPR and triglycerides levels were positively correlated in both smokers as non-smokers, and there was a negative association with the HDL fraction. In non-smokers, no association was encountered between CPR and cholesterol levels, or PCR with the LDL. However, CRP was statistically related to LDL in smokers (p<0,01).Conclusion. Healthy smokers have a higher serum concentration of CRP, LDL and triglycerides, whilst HDL levels are lower. Levels of CRP increase with triglycerides and have an inverse relationship with the levels of HDL in smokers and non-smokers. Levels of CRP and LDL are statistically related only in smokers (AU)

ABSTRACT

Introducción: Es nuestro objetivo determinar en qué medida el tabaco induce elevación de Proteína C Reactiva (PCR) en suero y definir el riesgo relativo de enfermedad inflamatoria subyacente en la población fumadora según los valores publicados por The Centers for Diseases Control and Prevention y la American Heart Association.Material y métodos: El presente estudio se ha llevado a cabo en una muestra sana masculina de 544 individuos, formada por personal aeronáutico cuyas edades se sitúan entre los 19 y los 60 años, media de 40 años con desviación típica de 10. De los 544 pilotos, 344 eran no fumadores y 200 fumadores. La PCR se determinó mediante el test ultrasensible.Resultados: La concentración sérica media en individuos no fumadores es de 1,6 mg/l (Intervalo de Confianza 95%: 1,4-1,7), mientras que en fumadores es de 2,09 mg/l (Intervalo de Confianza 95%: 1,9-2,3). El 65,5% de la población fuma-dora obtenía una PCR > 1 mg/l frente al 51,5% de la población no fumadora. Los fumadores tenían 27,3% más riesgo de presentar una PCR sérica superior a 1 mg/l (Riesgo Relativo: 1,273; Intervalo de Confianza 95%: 1,103-1,470) que los no fumadores.Discusión: La PCR es un buen marcador de inflamación, pudiendo utilizarse como factor predictivo de riesgo cardiovascular y de alteración broncopulmonar.Conclusiones: Se puede estimar el valor de 1,2 mg/l para la PCR en suero como referencia en una población masculina adulta sana. La edad y sobrepeso son factores que afectan a la relación entre tabaquismo y PCR sérica, pero es el consumo de tabaco el principal factor determinante de una elevación de la PCR


Introduction: We aim to determine up to what degree tobacco induces and elevation of C-reactive protein (CRP) in serum and define the relative risk of underlying inflammatory disease in the population that smokes according to the values published by the Centers for Diseases Control and Prevention and the American Heart Association.Material and methods: The present study was conducted in a healthy male sample of 544 individuals made up of aeronautic personnel whose ages ranged from 19 to 60 years, with a mean of 40 years and standard deviation of 10. A total of 344 out of the 544 pilots did not smoke and 200 smoked. The CRP was measured with the ultrasensitive test.Results: The means serum concentration in subjects who did not smoke was 1.6 mg/l (95% Confidence Interval: 1.4-1.7) while it was 2.09 mg/l (95 % Confidence Interval: 1.9-2.3) in those who smoked. A total of 65.5% of the population who smoked obtained a CRP > 1 mg/l versus 51.5% of the population who did not smoke. Those who smoked had 27.3% more risk of having a serum CRP value greater than 1 mg/l (Relative Risk: 1.273; 95% Confidence Interval: 1.103-1.470) than those who did not smoke.Discussion: CRP is a good marker of inflammation and can be used as a predictive factor of cardiovascular risk andbronchopulmonary disorder.Conclusions: The value of 1.2 mg/l for CRP in serum can be estimated as reference in a healthy adult masculine population. Age and overweightness are factors that affect the relationship between smoking and serum CRP. However tobacco consumption is the main determining factor of an increase in CRP (AU)

ABSTRACT

Introducción: La Proteína C Reactiva (PCR) es sintetizada en respuesta al daño tisular o a la infección. Se considera factor de riesgo cardiovascular emergente pues es un importante predictor del desarrollo de arteriopatía periférica y de eventos coronarios agudos. El objetivo de este estudio es describir el perfil lipídico de nuestra muestra, comprobar si existe relación entre PCR y valores de triglicéridos, colesterol y sus fracciones, según el hábito tabáquico y entre carga tabáquica y cifras de lípidos y PCR. Material y métodos: Se trata de un estudio observacional y transversal realizado en 762 varones. La PCR se determinó mediante ensayo Tina-Quant ultrasensible. Rangos de normalidad: PCR < 4 mg/l, colesterol 110-220 mg/dl, HDL< 35 mg/dl, LDL < 130 mg/dl, triglicéridos 50-180 mg/dl. La carga tabáquica se analizó a través del número de cigarrillos fumados al día y el índice paquetes/año (nº de cigarrillos diarios x nº de años de fumador/ 20). Los datos fueron analizados mediante el programa informático SPSS windows versión 12.0. Resultados: La edad media era de 41,74 (10,03) años. Doscientos(26,2%) eran fumadores, 344 (45,1%) no fumadores y 218 (28,2%) exfumadores. La media de la PCR fue significativamente mayor en los fumadores que en los no fumadores (2,097 ± 1,7 vs 1,57 ± 1,41; p =0,004). La cifra media de triglicéridos, colesterol y LDL fue mayor en los fumadores que en los no fumadores (p < 0,001, 0,3 y 0,14), respectivamente. La fracción HDL, como factor protector se encontraba aumentada en los no fumadores (p < 0,001). Existe una correlación positiva débil, tanto en fumadores como en no fumadores, entre PCR y cifras de triglicéridos (r = 0,285 y r = 0,2),y negativa con HDL (r = -0,45 y r = -0,182), estadísticamente significativa en ambos casos (p < 0,001 y p = 0,001). La correlación entre PCRy colesterol y LDL es débil. Es significativa en fumadores (p = 0,037), no siendo así en los no fumadores (p = 0,167). Hallamos una correlación débil entre el índice paquetes/año y los lípidos, que es más elevada para los triglicéridos (r = 0,3), con significación estadística (p < 0,001). La hallada para la fracción HDL es débil, negativa (r = -0,15) y estadísticamente significativa (p = 0,03). No hemos hallado correlación entre este índice y las cifras de PCR (r = 0,008). La correlación lineal entre nº de cigarrillos fumados al día y las variables lipídicas y PCR es prácticamente inexistente, siendo significativa solamente para los triglicéridos (p = 0,02). Conclusión: Las cifras de colesterol, cLDL, triglicéridos y PCR, se encuentran más elevadas en los fumadores que en los no fumadores. Las cifras de cHDL disminuyen en fumadores. Los niveles de PCR aumentan al incrementarse las cifras de lípidos, sobre todo en los sujetos fumadores varones estudiados. Al aumentar la carga tabáquica del fumador aumentan los valores de triglicéridos, colesterol, cLDL y disminuyen los de cHDL (AU)


Introduction: C-Reactive Protein (CRP) is synthesized in response to tissue damage or infection. It is considered to be an emergent cardiovascular risk factor since it is an important predictor of the development of peripheral arteriopathy and acute coronary events. This study aims to describe the lipid profile of our sample, verify if there is a relationship between CRP and triglycerides values, cholesterol and its fractions, according to the smoking habit and between smoking load and lipid and CRP values. Material and methods: This is an observational, cross-sectional study conducted in 762 men.The CRP was determined with the ultrasensitive Tina-Quant assay. Normality ranges: CRP35 mg/dl, LDL < 130 mg/dl, triglycerides 50-180 mg/dl. Smoking load was analyzed through the number of cigarettes smoked per day and the package/year index (no. of cigarettes daily x no. of years of smoker/20). The data were analyzed with the windows SPSS program, version12.0. Results: Mean age was 41.74 (10.03) years. Two hundred (26.2%) were smokers, 344 (45.1%) non-smokers and 218 (28.2%) ex-smokers. Mean CRP was significantly greater in smokers than in non-smokers(2,097 ± 1.7 vs 1.57 ± 1.41; p = 0.004). Mean value of triglycerides, cholesterol and LDL was greater in smokers than in non-smokers (p <0.001, 0.3 and 0.14), respectively. HDL fraction, as protector factor, was increased in the non-smokers (p < 0.001).There is a weak positive correlation both in smokers and non-smokers between CRP and triglycerides values (r = 0.285 and r = 0.2), and negative one with HDL (r = -0.45 and r = -0.182), that is statistically significant in both cases (p < 0.001 and p = 0.001). Correlation between CRP and cholesterol and LDL is weak. It is significant in smokers (p = 0.037), not being so in non-smokers (p = 0.167). We find a week correlation between packages/year index and lipids, which is higher for triglycerides (r = 0.3), with statistical significance(p < 0.001). That found for the HDL fraction is weak, negative (r = -0.15) and statistically significant (p = 0.03). We have not found a correlation between this index and the CRP values (r = 0.008). The linear correlation between no. of cigarettes smoked per day and lipid variables and CRP is practically non-existent, it only be significant for triglycerides(p = 0.02). Conclusion: Cholesterol, cLDL, triglycerides and CRP values are higher in smokers than in non-smokers. The cHDL values decrease insmokers. CRP levels increase as the lipid values increase, above all in the male smokers studied. When the tobacco load of the smoker is increased, triglycerides, cholesterol, cLDL values increase and cHDL ones decrease (AU)

ABSTRACT

Chemotaxis is a property common to all free cells or unicellular microorganisms. It is not a simple spontaneous cellular migration but one which is directed towards the source or nucleus, producer of the chemotactic substance. One of the first phenomenon which is established as a defense mechanism of the organism is the attraction of polymorphonuclears. In 1955 Rebuck and Crowley described a method, "skin window" for the study of in vivo leukocyte chemotaxis. The aim of this work was to go deeper into the study of this test and to establish its clinical use. Two hundred and seventy patients from both sexes were studied and divided into five groups: Group I - 60 healthy subjects as control. Group II - 60 patients with pathologic leukocyte response: 10 cirrhotics, 15 Hodgkin's disease, 15 chronic renal insufficiency, 2 drepanocytosis and 3 sarcoidosis. Group III - 60 patients with no theoretical alterations in the leukocyte chemotaxis: 22 bronchial asthma, 23 nonlymphoid neoplasm, 13 iritis and 2 histiocytosis X. Group IV - 40 active tuberculosis patients. Group V - 30 patients with bacterial pneumonia non-tuberculosis. The Rebuck test was carried out on all patients. As lymphocyte markers, E rosettes, superficial immunoglobulins and the lymphoblast transformation test against PHA were performed on all the groups of patients. As to the results obtained, the positive responses for Groups I, II, III, IV and V were 87%, 28%, 83.3%, 45% and 63.3%, respectively. These results were evaluated in relation to the Mantoux reaction. The modified Rebuck test is useful for leukocyte chemotactic study. This was found to be altered in 13% of the healthy population.(ABSTRACT TRUNCATED AT 250 WORDS)
