The study was conducted at the State Hospital of Sumare, in Sumare city, Sao Paulo state, Brazil. It was a randomized, double blind clinical trial, and the samples were selected from the employees of the hospital. Around 31 obese patients were recruited in the study, they were divided in to two groups, group1 was control, received Alanine and group 2 was test population, received L- Glutamine. The age group of patients were between 20 – 60 years and all had BMI> 25 kg/ m2. The blood samples were collected on day1 and 14; the body weight and height were measured on respective days. Blood sugar, BMI and 24 hour food record was documented. Institutional review board approved the …show more content…
This ratio is a good marker for obesity, decreased in the GLN group from 0.85 to 0.57, whereas it increased from 0.91 to 1.12 in the ALA group. The data was analyzed by using SAS software and continues variables were expressed as mean and SD. The sample size was not sufficient to draw a conclusion, and a study with higher number of samples needs to be conducted.
Clinical Implications
The study was conducted to answer the EBP question “Whether the supplementation of L- Glutamine can provide any change in gut bacterial flora compare to Alanine supplementation, could it be helpful to reduce the body weight?”. Though the methodology and procedures were at par with the international standard and the result is statistically significant, it is not sufficient to change the practice based on this outcome. The sample size is too small to conclude the outcome; it is only a pilot study.
