Recurrent Nephrolithiasis

Background. The present article studies a possible role of parathyroid hormone-related protein (PTHrP) in urolithiasis pathogenesis.Aim. To consider PTHrP level as a predictor of the urolithiasis development.Material and methods. We presented an analysis of treatment in 79 patients with primary and recurrent nephrolithiasis that had underwent surgical treatment in the Uronephrological Center of Scientific Research Institute – Ochapovsky Regional Clinical Hospital #1, Krasnodar from 2017 to 2019. All observed patients were divided in two groups: patients with primary and recurrent nephrolithiasis. A group of 10 relatively healthy people was included in the study as well. All patients and conditionally healthy people had a test for blood parameters; in particular, the level of parathyroid hormone-related protein was assessed in order to compare the indicators in all three groups.Conclusions. The PTHrP level was showed to be statistically significantly different in patients with urolithiasis from the group with relatively healthy people. Groups with primary and recurrent nephrolithiasis show not difference in the level of PTHrP. Further studies are necessary to consider this protein as one of the predictors of urolithiasis and study its role in the pathogenesis of nephrolithiasis.

ABSTRACT During pregnancy, a placental calcium pump maintains the fetus in a hypercalcaemic state relative to the mother, a condition which has been thought to facilitate normal development of the fetal skeleton. Based on experiments performed in the sheep, parathyroid hormone-related protein (PTHrP) has been implicated as the hormone responsible for maintaining the placental calcium pump. In the present study on mice in which the PTHrP gene has been ablated by homologous recombination, we have measured both fetal and maternal circulating total and ionised calcium levels, as well as fetal total body calcium, in order to determine whether absence of PTHrP during fetal development has an effect on fetal calcium levels. Our results show that, in fetuses lacking PTHrP, circulating ionised calcium levels are significantly lower than those of heterozygote and wild-type littermates, but circulating total calcium levels show no difference. Total body calcium levels of null mutants are significantly higher than those of normal littermates. The role of PTHrP in maintaining the integrity of the transplacental calcium pump in the rodent thus remains unclear. It may be that the lower levels of fetal blood ionised calcium in mutant animals are due to disruption of the placental pump, but, if this is the case, compensatory mechanisms have operated to allow the excessive calcium deposition seen in the skeletons of these animals. Alternatively, the increased avidity of the bones for calcium may in itself have produced a lower equilibrium level of available ionised calcium.
