About this study
Official title: Effect of Pentoxifylline Administration on Hemoglobin Level of Hemodialysis Patients
Our study investigated the effect of using a known drug used in intermittent claudication (named pentoxifylline) as an adjuvant to erythropoietin stimulating agents to improve anemia of hemodialysis patients.
Read the detailed description
Fifty out of 57 hemodialysis anemic patients were finally included. They were assigned to two groups of equal numbers. Oral Pentoxifylline 400mg once daily was added to the treatment group which was compared to the control group over a six months period regarding hemoglobin, hematocrit, serum albumin and CRP.
Inclusion criteria: (Patients with ESRD on HD who have hemoglobin <11 g/dl, taking Erythropoietin alfa 4000 -12000 I.U/wk and having a urea reduction ratio >65%.). There were 57 patients who met the inclusion criteria out of 158 patients.
Exclusion criteria: Iron deficiency anemia with transferrin saturation <30%, intact PTH>300pg/ml, vitamin B12 or folate deficiency (evidenced by macrocytosis), history of intolerance to pentoxifylline or other xanthine derivatives, recent retinal or cerebral hemorrhage or active peptic ulcer disease, pregnancy or breastfeeding, presence of systemic hematological disease or known hemoglobinopathy, major surgery, infection, acute myocardial infarction, or malignancy within the last three months and patients who refused to participate in the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PentoxifyllineDrug
Also called Trental
a known drug of xanthine derivatives used in intermittent claudication
| Study group | Role | What they receive |
|---|---|---|
| treatment group | Experimental | Group I: 29 patients (25 completed the study) that received the study agent (400mg of oral pentoxifylline daily for 6 months.), besides the appropriate weight-based dose of ESA (60-150I.U/kg/wk). Receives: Drug: Pentoxifylline |
| control group | No intervention | Group II: 28 patients (25 completed the study) who did not receive pentoxifylline but they received the appropriate dose of ESA. They were used as a control group and compared to group1 concerning the primary and the secondary outcomes. |
What is being measured
The primary outcome is the main question the study is designed to answer.
hemoglobin difference
the difference in haemoglobin concentration between the pentoxifylline and control group at the end of the 6 months study period.
Measured: after 6 months from the start
Secondary outcomes (1)
difference in inflammatory markers
Difference in CRP and albumin levels between the two groups
Measured: after 6 months from the start

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Pentoxifylline in people with Anemia of Chronic Kidney Disease, run by Tanta University at 1 site in Egypt.
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 1 inclusion and 1 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 8 Nov 2018. 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 Egypt. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
hemoglobin difference (time frame: after 6 months from the start). 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 NCT03731741, which also lists 4 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 8 Nov 2018.
