The role of urinary peptidomics in kidney disease research

Objective: the present study was aimed to evaluate the role of pharmaceutical services in improving the outcome of mineral bone disorder in patients with advanced chronic kidney disease. Methodology: One hundred and twenty patients with chronic kidney disease-mineral bone disorder (CKD-MBD) screened for eligibility, seventy-six patients enrolled in the study and randomly allocated into two groups: pharmaceutical care and usual care, both groups interviewed by the pharmacist using specific questionnaire for assessing the quality of life (QoL). All the drug related problems (DRPs) including drug-drug interactions (DDIs) were recorded by the pharmacist. Blood samples were collected and utilized for analyzing the levels of vitamin D, phosphorous, calcium, albumin and parathyroid hormone at baseline and three months after. The pharmaceutical care group received all the educations about their medications and how to minimize DRPs; improve the QoL. Additionally, the pharmaceutical intervention included correcting the biochemical parameters. Results: Pharmaceutical care significantly improved patients QoL and minimized DRPs and DDIs. It was also effective in improving the biochemical parameters. Conclusion: Pharmaceutical care has a positive impact on improving the outcome of patients with CKD-MBD through attenuating DRPs, improving the biochemical parameters and the QoL.

End Stage

In recent decades, the main pathogenetic mechanisms for maintaining muscle mass and strength have been discovered. Most of the scientific papers on the molecular aspects of the pathogenesis of sarcopenia were focused on the Akt-signaling pathway. The subject of the study were people of elderly and senile age, immobilized patients, patients with CKD 1-4 stages, animals. However, recently more attention has been paid to the role of protein – the mammalian target of rapamycin mTOR. It seems to be a key link in the control of muscle mass and is a promising marker in understanding the mechanisms of the pathogenesis of sarcopenia. Its importance in protein metabolism in patients with end stage kidney disease is not studied and requires further research. The presented scientific review contains information on the role of mTOR and its components – mTORC1 and mTORC2 in maintaining muscle mass and strength in a healthy person and in the formation of sarcopenia in patients with CKD. The general aid of mTORC1 complex is regulation of protein production which is necessary for cell growth and differentiation. mTORC2 complex functions are not enough studied. It is established that it plays important role in such biological processes as cytoskeleton organization, intracellular homeostasis maintaining, so it provides cell resistance and cell survivability in negative external and internal impulses. mTOR protein can be considered as promising molecular marker in diagnostics of protein metabolism early disturbances in patients with CKD and also as additory factor of sarcopenia severity assessment.
