Effect of probiotics on human blood urea levels in patients with chronic renal failure.
INTRODUCTION Patients with chronic kidney disease ( CKD ) show an increase in bowel aerobic bacteria that produce uremic toxins and decreased anaerobic bacteria as bifidobacteria and lactobacillus . The latter can be used as probiotics . The probiotic with greater availability in Mexico , is the lactobacillus casei shirota ( LcS ) , currently there is no known LcS specified dose that produces a benefit to the patient with CKD . OBJECTIVE To determine the effectiveness of two different LcS doses in achieving a decrease in urea concentrations of at least 10 % in patients with KDOQI stage 3 and stage 4 CKD . METODOLOGY : A simple r and omized , controlled clinical trial . Out patients treated at the National Institute of Medical Sciences and Nutrition Salvador Zubirán in México D.F. Patients were provided the LcS , as follows : Group A : 8 x 10(9 ) colony-forming units ( CFU ) and Group B : 16 x 10(9 ) CFU . Patients were followed-up for eight weeks , and baseline and final sample s were obtained to calculate the basal and final concentrations , respectively , of blood urea and serum creatinine ( CrS ) . During the follow-up , both groups consumed a diet of 30 kcal/kg/weight and 0.8 g/kg/weight of protein , and a food diary was made to assess both the adherence to the diet  and  LcS.  RESULTS Thirty patients with CKD were evaluated . When analyzing the percentage change between the different doses , a decrease > 10 % was found in the blood urea concentrations for patients treated with the 16 x 109 dose , which was significant with respect to the baseline measurement . CONCLUSION There was a > 10 % decrease in the serum urea concentrations with LcS in patients with stage 3 and 4 CRF
