Brief summary
The aim of the study is to assess the impact of pentoxifylline administration on the modulation of hyporesponsiveness to erythropoietin stimulating agents in hemodialysis patients
Detailed description
this is a prospective, randomized, controlled study to assess the impact of pentoxifylline administration on the modulation of hyporesponsiveness to erythropoietin stimulating agents in hemodialysis patients by determining several outcomes from the intervention and control groups at the end of the study.These outcomes include;the difference in hemoglobin and hematocrit concentration , the difference in inflammatory markers tumor necrosis factor Alpha (TNF-α), interleukin-1 Beta (IL-1β),the difference in the dosage of erythropoiesis stimulating agents ,and The erythropoietin stimulating agents (ESA) resistance index (ERI).

Eligibility
Inclusion criteria
* Adults (18 years or over). * Stable hemodialysis \>6 months. * Regular haemodialysis (3 times/ week). * ESA resistant anemia (Hb \<10 mg/dl for 6 mo.). * ESA dose of \>8000 IU/wk.
Exclusion criteria
* Inadequate hemodialysis. * Hyperparathyroidism (PTH\>800 pg/l). * Known hypersensitivity to, or intolerance of Pentoxifylline. * Absolute or functional iron deficiency (ferritin \< 100 μg/L and/or transferrin saturation \< 20%). * Presence of systemic haematological disease (including antibody-mediated pure red cell aplasia) or known haemoglobinopathy. * Major surgery, infection, inflammatory diseases, acute myocardial infarction or malignancy within the last 3 months. * Patients with chronic liver disease and patients who had received immunosuppressive therapy.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The difference in hemoglobin and hematocrit concentration between the intervention and control groups at the end of the study | up to 6 months post baseline | Patients will be evaluated regularly every month for hemoglobin concentration |
| safety & tolerability of pentoxifylline ( frequency of adverse drug effects due to Pentoxifylline as well as compliance with pentoxifylline). | up to 6 months post baseline | Patients will be evaluated regularly for frequency of adverse drug effects due to Pentoxifylline as well as compliance with pentoxifylline |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Inflammatory markers TNF-a, IL-1β. | up to 6 months post baseline | patient will be subjected to laboratory evaluation for estimation of IL-1β,TNF-α levels at baseline as well as end of study evaluation |
| Difference in the dosage of erythropoiesis stimulating agents. | up to 6 months post baseline | the dose of ESA will be assessed at end of study evaluation |
| The ESA ( erythropoiesis stimulating agents)resistance index (ERI). | up to 6 months post baseline | ERI will be assessed for patients by determining ESA dose and hemoglobin concentration |
