One-year Prospective Observational Study of BMI Change Effect of 5-alpha Reductase Inhibitor in Korean BPH Patients
This study is a prospective, 1-year follow-up, observational study. We are planning to
enroll 100 Korean patients with BPH. At each visit, patients' height, weight, abdominal
circumference will be checked. Laboratory parameters including fasting glucose, HbA1c, serum
testosterone, free testosterone, sex hormone-binding globulin, estradiol, maximum flow rate
(measured by flowmetry) will be tested. Blood test will be performed twice (at baseline and
at the end of study). 5mL of blood will be needed at each time from one subject. And total
IPSS score will be evaluated after 1 year of treatment of 5 ARI. At every visit, use of
above prohibited medicines and other medications will be investigated. In addition, any
surgical procedures undertaken during study period will be asked and recorded.
Subjects of study will be allocated into 3 separate groups. Group 1 will be those taking 5
alpha reductase inhibitor (dutasteride) only for 1 year. Group2 will be those who switch
from alpha blocker to dutasteride and take dutasteride for 1 year. Group 3 will be composed
of those taking both alpha blocker and dutasteride for 1 year.
