Urol Nefrol (Mosk). 1992 Jul-Dec(4-6):27-8.
Haptoglobin Hp phenotypes were determined in 104 patients with uroliths of different chemical composition and in healthy controls. 98 patients showed one of the three main phenotypes Hp (1-1, 2-1, 2-2). Electrophoretic motilities of protein fractions Hp were found out for the main phenotypes. Hp was not registered or its fraction motility was distinct from the main phenotypes in 6 patients. Hp phenotypes distribution obtained for all the examinees was compared to that of the controls. For healthy and total group of urolithiasis patients, for healthy and having CaPi and HVr nephroliths, the difference was insignificant in contrast to CaOx stones the incidence of which grew in Hp 1-1 carriers (p < 0.05). In view of this, Hp 1-1 phenotype can indicate a risk of oxalate urolithiasis.
