Treatment and Prognosis of Neurogenic Orthostatic Hypotension : A Prospective Randomized Study

September 23, 2021 updated by: Kon Chu, Seoul National University Hospital
Compare the effect of treatment of midodrine and pyridostigmine in neurogenic orthostatic hypotension and investigate the quality of life of treatment of neurogenic orthostatic hypotension.

Study Overview

Detailed Description

In patients with neurogenic orthostatic hypotension, the appropriate treatment was identified by comparing the treatment effects and side effects for each treatment drug. In addition, by confirming the effect of orthostatic hypotension on lowering the quality of life, it is expected that the improvement of the quality of life will help.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Orthostatic BP Drop
Time Frame: after 3-month medical treatment
Change of orthostatic SBP and DBP drop after 3-month medical treatment compared to initial results.
after 3-month medical treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of the Orthostatic Hypotension Associated Symptom Questionnaire (OH Questionnaire (OHQ)).
Time Frame: after 3-month medical treatment.

Change of the OH associated symptom survey result after 3-month medical treatment compared to initial results.

OHQ questionnaire has two components: the OH daily activity scale (OHDAS), which contains 4 items measuring the impact of OH on daily activities, and the OH symptom assessment (OHSA), which contains 6 items measuring the symptoms of OH (dizziness/light headedness, vision disturbance, weakness, fatigue, trouble concentrating, and head/neck discomfort).This questionnaire reflects the severity of OH-related symptoms on a 10-point scale, with 0 indicating the absence of a symptom and 10 indicating maximal severity.

** OHQ total score minimal 0 ~ maximal 100

after 3-month medical treatment.
Change of the Depression Score (Beck Depression Inventory-II )
Time Frame: after 3-month medical treatment.

Change of the depression score after 3-month medical treatment compared to initial results.

21 multiple-choice questions, each of which can be scored from 0 to 3. Higher score represent higher degree of depression.

Score Normal; 0-13, Mild depression; 14-19, Moderate depression; 20-28, Severe depression; 29-63

after 3-month medical treatment.
Short-form 36 Version 2
Time Frame: changes at 3 months after treatment

changes in Short Form (36) Health Survey version 2 (SF-36v2) physical component summary scale (PCS) compared to the baseline

SF-36v2 measures eight HRQOL domains (physical functioning, role limitation caused by physical problems, bodily pain, general health, vitality, social functioning, role limitation caused by emotional problems, and mental health) summarized into two summary scales that are normalized to the population (mean=50, standard deviation=10): the physical component summary scale (PCS) and the mental component summary scale (MCS).20 Better HRQOL is reflected by higher SF-36v2 scores.
