About this study
Participants and study design:
Subjects were recruited and selected for uremic patients on maintenance hemodialysis (HD) who informed us of their interest in the investigators study and were mentally capable to give an informed written consent and willing to comply with study requirements. The inclusion criteria were 18 years or older, with at least 3 months maintenance HD. The exclusion criteria were malignancy, acute infection, gastrointestinal bleeding, pregnancy, and inability to comply with the requirements of study.
69 respondents were enrolled in this trial. A single-center quasi-randomized controlled clinical trial was designed based on the patients in the care of one attending physician. Eligible subjects were allocated to study and control group, and the basic characteristics between the experimental group and control group were matched. There was no significant difference regarding gender, aged, education level, comorbidities between these two groups. The experimental group was treated with Ren Shen Yang Rong Tang (R-S-Y-R-T) combined routine western medicine, and the control group was treated with WM alone. The experimental group had 32 respondents and the control group had 37 respondents. The duration of use of R-S-Y-R-T was 6 months. Finally, there were 27 patients in the experimental group and 32 patients in the control group completed the study. Blood investigation, including biochemical profiles and inflammatory markers were checked at intervals 0, 2, 4 and 6 months form routine HD. The questionnaire, for the assessment of quality of life (QOL) was evaluated at interval 0, and 6 months.

Study medication and dosage:
For this study, the investigators used herbal granules prepared according to the formula of R-S-Y-R-T. The investigators purchased the study products from a manufacturer with a Good Manufacturing Practice (Si Wu Tang) certification in Taiwan. This was a concentrated decoction made by water extraction in 1:13 ratio from single batched roots of the 14 plants in proportions: Radix Paeoniae alba (Bai Sau) (90 g), Radix Angelicae sinensis (Dang Guay) (30 g), Pericarpium Citri Reticulatae (Chenpi) (30 g), Radix Astragali (Huangqi) (30 g), Cortex Cinnamomi (Rougui) (30 g), Radix Ginseng (Renshen) (30 g), Rhizoma Atractylodis Macrocephalae (Baizhu) (30 g), Radix Glycyrrhizae (Gancao) (30 g), Radix Rehmanniae praeparata (Soe Dee Huang) (20 g), Fructus Schisandrae (Wuweizi) (20 g), Poria cocos (Fuling) (20 g), Cortex et Radix Polygalae (Yuanzhi) (15 g), Zingiber officinale Roscoe (Jiang) (30 g)，Fructus Jujubae (Dazao) (10 g) as prepared according to the original pharmacopoeia. The plant origins in China were known to the buyer of the pharmaceutical company and the final product was free of E. coli, Salmonella and pesticide residues. The levels of heavy metals were 1.238 ppm for lead, 0.228 ppm for arsenic,0.10 ppm for cadmium, and <0.0022 ppm for mercury, all within regulated limits (5, 5, 0.5, and 0.5 ppm, respectively). Each pack weighed approximately 500 mg in aluminum packets.
The investigators determined the dosage of 1 pack a time for 3 times a day with warm water for 6 months. The exact number of packs taken was recorded in clinic visits and any unfinished packs were brought back to the study nurse at the next clinic visit.

What is being measured
The primary outcome is the main question the study is designed to answer.
Inflammatory markers
These inflammatory markers include c-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). We use the xMAP serum assay for the 3 cytokines.
Measured: Average 26 weeks (6 months)
Secondary outcomes (1)
Quality of life
We use the Taiwan version of the WHOQOL-BREF (WHOQOL-BREF [TW]).
Measured: Average 26 weeks (6 months)

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Add R-S-Y-R-T (500 mg 3 times per day) for 6 months and Routine western medicine in people with Immune Dysfunction, run by Tri-Service General Hospital (TSGH) at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Inflammatory markers (time frame: Average 26 weeks (6 months)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02053740, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2014.
