[Comparison of the determination of azotorrhea and steatorrhea in cystic fibrosis of the pancreas].

Steatorrhea and azotorrhea are evaluated, by Van de Kamer and Kjendalh methods, in 24 patients affected by cystic fibrosis in the diagnosis and in their evolution. High values were obtained for steatorrhea in 87.5% of the cases and for azotorrhea in the 79.1% at the moment of diagnosis. Steatorrhea and azotorrhea have been correlated obtaining a high statistic significant for p less than 0.01 in the diagnosis and in patients who followed treatment with the same medication, not being significative for all patients during their evolution. With results obtained, determination of fecal nitrogen, is positively evaluated not only in the diagnosis but also in the evolution of these patients to obtain an optimum nutritious condition.
