ABSTRACT

INTRODUCCIÓN: La colitis eosinofílica y la colitis de la enfermedad inflamatoria intestinal, son dos entidades que pueden compartir similares características clínicas, endoscópicas y terapéuticas pero diferentes criterios diagnósticos. OBJETIVOS: Describir el caso clínico de un niño preescolar con antecedente de alergia alimentaria, de hospitalizaciones y uso de antibióticos por varias ocasiones, que evoluciona con diarrea crónica intermitente. CASO CLÍNICO: Se trata de un paciente masculino, de 3 años 5 meses, con antecedente de alergia alimentaria con cuadro crónico de dolor abdominal, diarrea y retraso en el crecimiento. Se realiza abordaje de diarrea crónica. RESULTADOS: Con hallazgos clínicos de enfermedad inflamatoria intestinal y descripción histopatológica de colitis eosinofílica, se considera la asociación entre estas dos patologías sin dejar la posibilidad de que esta última se trate de una fase inicial de enfermedad inflamatoria intestinal. CONCLUSIONES: El tratamiento de pacientes con colitis eosinofílica complicada es similar a la enfermedad inflamatoria intestinal, se requiere seguimiento clínico, endoscópico e histopatológico de pacientes con colitis eosinofílica a largo plazo.


INTRODUCTION: Eosinophilic colitis and inflammatory bowel disease colitis are two entities that may share similar clinical, endoscopic and therapeutic features but different diagnostic criteria. OBJECTIVES: To describe the clinical case of a preschool child with a history of food allergy, hospitalizations and use of antibiotics for several occasions, who evolves with chronic intermittent diarrhea. CLINICAL CASE: This is a male patient, 3 years 5 months old, with a history of food allergy with chronic abdominal pain, diarrhea and growth retardation. Chronic diarrhea was approached. RESULTS: With clinical findings of inflammatory bowel disease and histopathological description of eosinophilic colitis, the association between these two pathologies is considered without leaving the possibility that the latter is an initial phase of inflammatory bowel disease. CONCLUSIONS: The treatment of patients with complicated eosinophilic colitis is similar to inflammatory bowel disease, clinical, endoscopic and histopathological follow-up of patients with eosinophilic colitis is required in the long term.

ABSTRACT

As proteínas do leite de vaca são os principais alérgenos relacionados à alergia alimentar em crianças e o diagnóstico inclui a realização do teste de provocação oral duplo cego placebo controlado (TPODCPC). Apesar da acurácia, este teste envolve riscos, necessita condições especiais para sua realização e apresenta limitações em crianças de baixa idade e em pacientes anafiláticos. Assim, há necessidade de métodos diagnósticos alternativos, entre eles o estabelecimento de pontos de corte de concentrações de IgE sérica específica para leite de vaca, que permitam o diagnóstico mesmo sem a realização do TPODCPC. O objetivo deste estudo foi estabelecer uma concentração discriminante de IgE sérica específica para leite de vaca e suas frações protéicas para o diagnóstico de alergia à proteína do leite de vaca (APLV) e avaliar se há diferentes concentrações discriminantes de IgE específica para este alérgeno no grupo de pacientes com anafilaxia. Realizou-se um estudo de coorte histórica incluindo pacientes com APLV e grupo controle composto por pacientes com suspeita não confirmada de APLV. Para estes objetivos, foram construídas curvas ROC para os seguintes alérgenos: leite de vaca, caseína, a-lactoalbumina e b-lactoglobulina. Os níveis de IgE específica foram avaliados posteriormente, em separado, nos pacientes com anafilaxia. Foram incluídos 123 pacientes (1,3M:1F mediana = 1,91 anos, com idade de 3,5 meses a 13,21 anos) com diagnóstico confirmado de APLV através de TPODCPC (n=26), presença de anafilaxia à proteína do leite de vaca (n=46) ou história clínica fortemente sugestiva de APLV associada à pesquisa positiva de IgE específica através de teste cutâneo (n=51). Entre os 65 pacientes com anafilaxia, 19 confirmaram o diagnóstico posteriormente, através de testes de provocação. O grupo controle foi composto por 61 pacientes (1M:1,1F) com idade variando entre 0,66 e 16,7 anos (mediana= 6,83 anos). A metodologia adotada para estabelecimento dos pontos de corte...


Cow's milk proteins are the main allergens related to food allergy in children and the diagnosis include the double blind placebo controlled food challenge (DBPCFC). Although this test presents accuracy, it involves risks, it is necessary special conditions and it presents limitations in infants and anaphylactic patients. It is necessary other diagnostic methods, among them the cut off values for IgE specific for milk to allow the cow's milk allergy (CMA) diagnosis without the need to perform the DBPCFC. The objective of this study was to establish a discriminating concentration of specific IgE to cow's milk and its proteins fractions for the diagnosis of allergy to CMA and to assess if there are different discriminating concentrations of specific IgE to this allergen in the group of patients with anaphylaxis. It was carried out a historical cohort study including patients with CMA and the control group was composed by patients with excluded CMA suspicion. To obtain the cutoff points for diagnosis of CMA , ROC curves were constructed for the following allergens: cow's milk, casein, a-lactalbumin and a b-lactoglobulin. The levels of specific IgE were later evaluated, separately, in patients with anaphylaxis. The study included 123 patients (1.3 M: 1F median = 1.91 years, ranging from 3.5 months to 13.21 years) with confirmed diagnosis of CMPA through DBPCFC (n = 26), the presence of anaphylaxis triggered by cow's milk protein (n = 46) or strongly suggestive clinical history associated with positive specific IgE through skin test (n = 51). Among the 65 patients with anaphylaxis, 19 confirmed the diagnosis through challenge tests. The control group was consisted of 61 patients (1M: 1.1 F) with ages ranging between 0.66 and 16.7 years (mean 6.86, median = 6.83 years). The methodology to stablish the cutoff was the construction of a ROC curve and subsequent calculation of positive and negative predictive value. The cutoff points obtained considering a 98%...
