To the Editor.—
I refer to the article "Serum Creatinine, Urea, and Protein Level Changes in Hydatidiform Mole" by Pour-Reza et al (230:580, 1974). Provided that their controls were properly chosen, protein intake or deficiencies, which were not discussed, should be comparable in both groups. A more reasonable conclusion is that a molar pregnancy makes greater demands than normal on body stores of nitrogen.
