ABSTRACT

PURPOSE:

To assess the nutritional status of children with congenital heart disease with left-to-right shunt and the nutritional disturbances related to the presence of pulmonary hypertension (PH).

METHODS:

In a prospective study, the nutritional status of 30 children with left-to-right shunt (16 with and 14 without PH) was determined by anthropometric parameters and plasma proteins albumin, transferrin and prealbumin. Frequency and extent of nutritional disturbances were analysed in relation to the presence of PH. A control group of 20 well-nourished children was formed, aiming to compare the values of the serum proteins.

RESULTS:

The nutritional classification according to Waterlow's criteria showed an overall prevalence of malnutrition of 83.3, which was higher in those with PH (p = 0.0140). This patient's group was more wasted than the group without PH (median z score of weight for height -1.65 vs -0.78). There was a high occurrence of measurements of arm fat area below the 5th percentile, which were similar in both groups. Serum levels of albumin and prealbumin were significantly lower in children with congenital heart disease than in the control group and transferrin values were similar in both.

CONCLUSION:

The prevalence of malnutrition was high. The presence of PH was associated with higher nutritional disturbance. The nutritional assessment may be a good way to identify diagnostic groups at particular risk of failure to thrive. This can be useful in planning a management which ensures these patients to achieve adequate nutritional supplementation in early life
RESUMO
Objetivo - Avaliar o estado nutricional de crianças portadoras de cardiopatias congênitas com shunt esquerda-direita e o grau de desnutrição relacionado à presença de hipertensão pulmonar (HP). Métodos - Em estudo prospectivo, foi avaliado o estado nutricional de 30 crianças cardiopatas com shunt esquerda-direita, sendo 16 com e 14 sem HP. Os parâmetros nutricionais utilizados foram peso, estatura, área adiposa do braço, área muscular do braço e as proteinas séricas albumina, transferrina e pré-albumina, cujos valores foram comparados aos de um grupo controle de 20 crianças eutróficas. Resultados - A prevalência de desnutrição foi de 83,3%, sendo superior no grupo com HP (p=0,0140); onde a redução da relação de peso para estatura foi mais freqüente (p=0,0140) e o escore z mediano de peso esperado para estatura, significantemente inferior ao observado no grupo sem HP (-1,65 vs -0,78). Os níveis séricos de albumina e de pré albumina nos cardiopatas foram significantemente inferiores ao do grupo controle. Conclusão - A prevalência de desnutrição foi elevada, com comprometimento das reservas calóricas e das proteínas viscerais. A presença de HP esteve associada a maior agravo nutricional nas crianças estudadas. A avaliação nutricional pode permitir o reconhecimento de pacientes com maior risco de desenvolver desnutrição, auxiliando seu planejamento nutricional e cirúrgico
