About this study
Official title: Baskent University Nephrology Department
The aim of the study is to investigate the factors influencing hemoglobin variability with inflammatory and nutritional parameters and its associations with all-cause mortality among hemodialysis patients.
Read the detailed description
Fluctuation in hemoglobin levels that is known as hemoglobin variability during treatment with ESA is a well-documented phenomenon. Several factors have been found to affect hemoglobin variability, including drug related, such as pharmacokinetic parameters, patient-related differences in demographic characteristics and factors affecting clinical status, as well as clinical practice guidelines, treatment protocols and reimbursement policies. Inflammation is also an important factor associated with hemoglobin variability, and the consequences of persistent inflammatory activity are far-reaching in affected patients.
In present study, the factors influencing hemoglobin variability with inflammatory and nutritional parameters and its associations with all-cause mortality among hemodialysis patients are investigated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| L Hemoglobin | L Hemoglobin: consistently low all 6 months with low hemoglobin levels | |
| T Hemoglobin | T Hemoglobin; consistently within the target range all 6 months with target-range hemoglobin levels | |
| H Hemoglobin | H Hemoglobin: consistently high all 6 months with high hemoglobin levels | |
| LAL Hemoglobin | LAL Hemoglobin: low amplitude fluctuation with low hemoglobin; all 6 months with low or target range hemoglobin levels | |
| LAH Hemoglobin | LAH Hemoglobin: low-amplitude fluctuation with high hemoglobin levels 6 months with target-range or high hemoglobin levels) | |
| HA Hemoglobin | HA Hemoglobin ; high-amplitude fluctuation low, target-range, and high hemoglobin levels within the 6 month period |

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?
Factors Influencing Hemoglobin Variability and Its Association with Mortality in Hemodialysis Patients (time frame: six month). 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 NCT03454906, which also lists 1 linked publication.
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.
