ABSTRACT

Se estima que niños alérgicos desarrollen tolerancia oral durante los primeros años de vida con una dieta de eliminación de lácteos. Determinar el tiempo de desarrollo de tolerancia oral a la proteína de leche de vaca, características clínicas y laboratorio. Estudio prospectivo, seguimiento durante 10 años, de niños con alergia a proteína de leche de vaca. Se indicó dieta de eliminación por 4 semanas con posterior reto. Se solicitó IgE total y específica. Se registro edad y tiempo de dieta al confirmarse la tolerancia. 81 niños, 33/81(40,74%) femeninos y 48/81(59,25%) masculinos, edad promedio de diagnóstico 6,22 meses(rango <1-42). Alergia no mediada IgE 32/81 (39,50%) y alergia mediada IgE 49/81 (60,49%); IgE específica para leche de vaca positivo en 55/81 (67,90%). Diagnóstico por respuesta positiva a la dieta de eliminación en 62/81 (76,54%) y con reto en 19/81 (23,45%). Desarrollaron tolerancia después de 12-18m con dieta, 21/32 (65,62%) con alergia no IgE a los 1,6 años y 23/49 (46,93%) con alergia IgE a los 2,13 años. Los niños restantes toleraron entre 19-24m, a los 2,35 y 2,80 años para la alergia no IgE e IgE respectivamente. Después de 36m, continuaron sin tolerar 5 niños entre ambos grupos con progreso a alergia alimentaria múltiple. El diagnóstico de alergia puede basarse en la respuesta positiva a la dieta de eliminación de lácteos, el reto es necesario en casos inciertos y la tolerancia se alcanza a una edad más temprana en niños con alergia no mediada IgE


It is estimated that allergic children develop oral tolerance in the early years of life with a dairy elimination diet. To determine the time development of oral tolerance to cow's milk protein, clinical and laboratory. A prospective study followed for 10 years, children allergic to cow's milk protein. He said elimination diet for 4 weeks after challenge. Was requested total IgE and specific. Age and time was recorded to confirm diet tolerance. 81 children, 33/81 (40.74%) were female and 48/81 (59.25%) male, average age at diagnosis 6.22 months (range <1-42). IgE-mediated allergy is not 32/81 (39.50%) and IgE-mediated allergy 49/81 (60.49%) specific IgE to cow's milk positive in 55/81 (67.90%). Diagnosis by positive response to the elimination diet in 62/81 (76.54%) and challenge in 19/81 (23.45%). Tolerance developed after 12-18m with diet, 21/32 (65.62%) with non-IgE allergy to 1.6 years and 23/49 (46.93%) with IgE allergy to 2.13 years. The remaining children tolerated between 19-24m, to the 2.35 and 2.80 years for non-IgE allergy and IgE, respectively. After 36m, continued without tolerating 5 children between the two groups with multiple food allergy progress. The diagnosis of allergy can be based on positive response to milk elimination diet, the challenge is necessary in uncertain cases and tolerance is reached at an earlier age in children with IgE mediated allergy is not

ABSTRACT

La Hipertensión Portal (HTP) en niños es de difícil manejo debido a múltiples etiologías y al empleo de tratamientos no estandarizados. Reportar la historia natural de la HPT en niños atendidos en la Unidad, evaluar la evolución y el impacto del tratamiento en el pronóstico. 27 pacientes evaluados desde 1999 hasta 2009. Registro de: etiología, clínica, laboratorio, Eco- Doppler clasificación endoscópica de las várices esofágicas, gástricas y fúndicas, Child-Pugh y terapéutica endoscópica. 18/27(66,66%) Cavernomatosis de la Porta, 3/27(11,11%) Cirrosis Hepática Secundaria a Hepatitis Auto-inmune, 3/27(11,11%) Fibrosis Hepática Congénita, 2/27(7,40%) Colestasis Intrahepática Familiar y 1/27(3,70%) Síndrome de Budd Chiari; promedio de edad 4,6 años +/- 4,47. Debutaron con hemorragia digestiva superior 17/27(62,96%). Varices Esofágicas grado III 13/27(48,14%) y grado IV 4/27(14,81%); Gastropatía hipertensiva severa 5/27(18,51%), Várices gastroesofágica tipo II 9/27(33,33%). Profilaxis Primaria con propanolol 9/27(33,33%) y 1/27(3,70%) ligadura endoscópica más propanolol. Profilaxis secundaria: 17/27(62,96%), con ligadura endoscópica 47,05%, Escleroterapia 35,29% y ligadura más esclerosis 17,64%. Uso de somatostatina 2/17(11,76%) y falla en el control de hemorragia post-tratamiento 1/17(5,88%). Child Pugh B 4/27(14,81%) y Child Pugh C 4/27(14,81%). Posterior al Tratamiento: erradicación de várices esofágicas con ligadura endoscópica en 50% contra 35,71% con la escleroterapia (p< 0.05), un promedio de 2 +/- 1,41 sesiones vs 3,4 +/- 1,78 respectivamente. Resangrado en 2/17(11,76%). En niños con cirrosis con Child Pugh B y C con terapéutica endoscópica compensaron la afectación hepática. Un seguimiento 5,3 años: mortalidad de 1/27(3,70%), un trasplante hepático, 2 derivación porto-cava y 3 en espera. La profilaxis primaria o secundaria indicada disminuyo el riesgo de hemorragia variceal con pocas complicaciones, y mejoró el pronóstico de los pacientes...


Portal Hypertension (PHT) in children is hard to handle with as a result of multiple etiologies and because of using non standardized treatments. Reporting the PHT’s natural history in children assisted in the Unit, assessing the evolution and impact of the treatment in the prognosis. 27 patients assessed between 1999 and 2009. The following was recorded: etiology, clinic, laboratory, Eco-Doppler, endoscopic classification of esophageal, gastric and fundic varices, Child-Pugh, and endoscopic therapy. 18/27 (66.66%), Portal Cavernomatosis; 3/27 (11.11%), Secondary Liver Cirrhosis to Autoimmune Hepatitis; 3/27 (11.11%), Congenital Hepatic Fibrosis; 2/27 (7.40%), Familial Intrahepatic Cholestasis; and 1/27 (3.70%), Budd-Chiari Syndrome; average age: 4.6 ± 4.47. First time with upper digestive hemorrhage: 17/27 (62.96%). Grade III Esophageal Varices, 13/27 (48.14%); and Grade IV: 4/27 (14.81%); Severe Hypertensive Gastropathy: 5/27 (18.51%); Type-II Gastro-esophageal Varices: 9/27 (33.33%). Primary prophylaxis by Propanolol: 9/27 (33.33%); and endoscopic ligature plus Propanolol: 1/27 (3.70%). Secondary prophylaxis: 17/27 (62.96%); with endoscopic ligature: 47.05%; Sclerotherapy: 35.29%; and ligature plus sclerosis: 17.64%. Usage of somatostatin: 2/17 (11.76%); and failure in controlling post-treatment hemorrhage: 1/17 (5.88%). Child-Pugh B: 4/27 (14.81%); and Child-Pugh C: 4/27 (14.81%). Post-Treatment: eradication of esophageal varices by endoscopic ligatures in 50% vs. 35.71% with sclerotherapy (p< 0.05), a 2 ± 1.41 average of sessions vs. 3.4 ± 1.78, respectively. Rebleeding in 2/17 (11.76%). Children with cirrhosis, with Child-Pugh B and C, compensated the hepatic disturbance with endoscopic therapy. A 5.3-year follow-up: 1/27 (3.70%) morbidity; one liver transplantation; 2 portal-cava derivation, and 3 in the wait list. The prescribed primary or secondary prophylaxis diminished the risk of varicose hemorrhage with few complications...
