RESUMO
La influencia de la desnutrición sobre la efectividad de un suplemento de lactobacilos vivos para prevenir y curar cuadros de diarrea infantil se estudió sobre 200 niños entre 6 y 24 meses de edad, desnutridos (D) o controles (C) que recibieron a ciegas durante 90 días leche fermentada con L. Acidofilus y L. Casei (10 elevado a la 7 - 10 elevado a la 8/ml) (LB) o cantidad equivalente de leche fluida pasteurizada (L). Los episodios de diarrea se clasificaron según su duración fuera 1-4, 5-14 y diarrea prolongada (DP) si duraba más de 14 días. Los 119 niños que completaron el estudio se dividieron en 4 grupos: D-L: n=25; D-LB: n=32; C-L: n=27 y C-LB: n=35. Los aspectos preventivos se evaluaron a través del número de episodios y los terapéuticos a través de la duración de los mismos. Durante el estudio se registraron 134 episodios: 29 en D-L; 48 en D-LB; 37 en C-L y 20 en C-LB. Se presentaron 12 DP, todas en los grupos L: 3 en los controles y 9 en los desnutridos. En el grupo D-LB más del 90 por ciento de los episodios fueron de muy corta duración, porcentaje muy superior al de D-L y similar al observado en C-LB. En conclusión, la leche fermentada fue capaz de prevenir la mitad de los episodios en los controles, pero fue ineficaz en los desnutridos; sin embargo, fue efectiva para acotar la duración y evitar las DP con independencia del estado nutricional. Por ende la desnutrición afectó los aspectos preventivos de los lactobacilos que requieren del sistema inmune, pero no los curativos, eminentemente locales

The influence of undernutrition on the effectiveness of a dietary supplement of live lactobacillus regarding prevention and treatment of infantile diarrhoea was studied on 200 children 6 to 24m old. Children, undernourished (D) or controls (C), received for 90 days, in a blind experiment, a fermented milk providing L. Acidofilus y L. Casei (10(7)-10(8)/ml) (LB) or an equivalent amount of fluid milk (L). diarrhoea episodes were recorded and classified according duration: 1-4, 5-14 days, and protracted diarrhea (DP) those lasting beyond 14 days. Study requirements were fulfilled by 119 children: D-L: n=25; D-LB: n=32; C-L: n=27 y C-LB: n=35. Preventive aspects were evaluated through number of episodes and through their lasting the therapeutic ones. Episodes recorded were 134: 29 in D-L; 48 in D-LB; 37 in C-L and 20 in C-LB. In the D-LB group over 90% episodes were very short (1-4 days), percentage far higher to that observed in D-L and similar to C-LB. There were 12 episodes of DP, 9 D and 3 in C, all in the L groups. In conclusion, although the fermented milk prevent half episode in the controls but not in the undernourished, it was able to shorter episodes duration and prevent protracted diarrhoea irrespectively of nutritional status. Therefore, undernutrition impaired the ability of the lactobacillus supplement to prevent children diarrhoea, which implicates immune system, but not curative effects which are the result of local actions.

The efficacy of probiotics on persistent diarrhea remains uncertain. The purpose of this study was to evaluate the effect of Lactobacillus sp and Saccharomyces boulardii on persistent diarrhea in children. In a double-blind trial eighty-nine children, aged 6-24 months were randomly distributed to receive pasteurized cow milk containing 2 viable lyophilized strains Lactobacillus casei and Lactobacillus acidophillus strains CERELA, (10(10)-10(12) colony-forming units per g) (n = 30), or lyophilized S. boulardii, (10(10)-10(12) colony forming units per g) (n = 30) or pasteurized cow milk as placebo (n = 29); on each diet 175 g was given twice a day for a 5 day period. Number of depositions, duration of illness and frequency of vomiting were considered. Enteric pathogens were isolated from stools in 40% of the patients, 27% had rotavirus. Lactobacillus and S. boulardii significantly reduced the number of depositions (p < 0.001) and diarrheal duration (p < 0.005). Similarly both significantly (p < 0.002) reduced vomiting as compared with placebo. There was no difference between treatments depending on rotavirus status. In conclusion, L. casei and L. acidophillus strains CERELA and S. boulardii are useful in the management of persistent diarrhea in children.

One hundred children 6 to 24 month old, normal or undernourished according to weight for height index, received during three months--autumn to winter--a dietary supplement of live Lactobacillus acidophilus and Lactobacillus Casei, 10(7)-10(8)/ml in fermented milk (LB) or an equivalent amount of fluid milk (L) as control. Children's follow-up was performed as outpatients in the Hospital Posadas (Great Buenos Aires). Episodes of respiratory tract infections were recorded and classified according to severity as: Pneumonia (N); Bronchitis (B), Recurrent Obstructive Bronchitis (BOR) and upper respiratory tract infections (CVAS). 58% of children fitted the study protocol, 22 in the LB and 36 in the L group; 21 were undernourished and 37 presented normal weight/height. No deaths were recorded. Total episodes were 103: 34 in LB and 69 in L, that means a frequency of 1.55 and 1.92 episodes/children respectively. In LB a maximum of 3 episodes/children was recorded, meanwhile the number reached 7 in L (p = 0.0373). Severity was higher in L than LB: 0.06 vs. 0 for N; 0.69 vs. 0.45 for B + BOR and 1.17 vs. 1.09 for CVAS. In the control group frequency of severe pathologies was about twice in undernourished than in normal: 0.08 vs. 0.04 for N; 1.08 vs. 0.50 for B + BOR; no difference was found for CVAS. Live lactobacillus supplement suppressed pneumonia and decreased bronchitis in undernourished as well as in normal. In this study undernutrition not only increased the chance of suffering severe acute respiratory tract infections but also impaired the effectiveness of the supplement to decrease severity. The effect is explained on the basis of the immunocompetence depression linked to an inadequate nutritional status.

Se estudiaron 100 niños de alto riesgo social entre 6 y 24 meses de edad, clasificados como normales o desnutridos, según el indicador antropométrico Peso/talla por ciento, que recibieron a ciegas durante 3 meses, entre el otoño y el invierno, un suplemento de L.acidophilus y L.casei vivos, en una concentración de 10 a la 7-10 a la 8/ml de leche fermentada (Grupo LB) o una cantidad equivalente de leche fluida pasteurizada (Grupo L), utilizada como control para descartar posible efectos inespecíficos del vehículo. Los niños fueron controlados en los consultorios externos del Hospital Prof. Dr. A. Posadas (gran Buenos Aires), registrándose todos los episodios de patologías de vías respiratorias (OVR). La severidad se cuantificó de acuerdo al código de enfermedades de la OMS como: catarro de vías aéreas superiores (CVAS), bronquitis (B), bronquitis obstructiva recurrente (BOR) y neumonía (N). De los 58 niños que completaron el estudio, 22 pertenecían asl grupo LB y 36 al grupo L; 21 fueron clasificados como desnutridos y 37 presentaron un valor de P/T por ciento dentro de los límites normale. Durante el período del estudio no se registraron muertes. se registraron 103 episodios de patologías de vías respiratorias, 34 en el Grupo LB y 69 en el control, con una frecuencia de 1,55 y 1,92 episodios/niño respectivamente. En el grupo LB se registró un máximo de 3, mientras que en el L se llegó a 7 episodios/niño (p = 0,0373). El análisis de las patologías por gravedad mostró mayor severidad en el grupo L que en el LB: 0,06 vs 0 para neumonías; 0,69 vs 0,45 para B + BOR y 1,17 vs 1,09 para CVAS. En los desnutridos que consumieron leche control, la frecuencia de las patología de mayor severidad duplicó la de los normales: 0,08 vs 0,04 para las neumonias, 1,08 vs 0,50 para las bronquitis, sin diferencias para el CVAS. El suplemento de lactobacilos previno las neumonías y disminuyó la frecuencia de las bronquitis en normales y desnutridos. En este estudio la presencia de desnutrición incrementó la predisposición hacia las patologías de mayor severidad y limitó la efectividad del suplemento para morigerar la gravedad, probablemente por limitar la capacidad del organismo para llevar a cabo la respuesta inmune
