Comparação do estado nutricional em pacientes com insuficiência renal crônica com e sem hiperparatireoidismo secundário

Objective: To compare by means of a specific instrument (Malnutrition Inflammation Score - MIS) and dietary recall, the nutritional profile of patients with chronic renal failure (CRF) on hemodialysis with and without Secondary Hyperparathyroidism (HPT2). Methods: cross-sectional study with 204 patients with CRF on hemodialysis with and without HPT2. Nutritional status was assessed by means of the MIS instrument and food intake by 24-hour recall. Data from the latter was analyzed using Avanutri® software. Results: Of the total patients, 136 had HPT2 and 68 did not, most of them being male, alcoholic and sedentary in both groups. Regarding MIS, validated instrument to assess nutritional risk, the number of patients with a score> 6 (indicating nutritional risk) was 48.5% for those without HPT2 and 49.3% for those with HPT2, however, there was no statistical difference between the groups (p> 0.05). Regarding the consumption of micronutrients, it was found that people with CRF and HPT2 consumed in greater quantities all micronutrients, except for vitamin B12. With regard to micronutrients that can directly intervene in HPT2, vitamin D and phosphorus were significantly more consumed by the group with CRF and HPT2.Conclusion: There was no statistical difference in the nutritional status of patients with CRF on hemodialysis with and without HPT2. Patients with CRF and HPT2 consumed a greater amount of all micronutrients, especially vitamin D and phosphorus, but maintained adequate serum levels, which may indicate the fulfillment of specific recommendations for the treatment of HPT2.
