Objectives: In this randomized double-blind placebo-controlled clinical trial we assess the effects of processed honey and royal jelly on the symptoms of CRF.
Design: Processed honey and royal jelly, made under standard-state conditions with the permission of food and drug organization of ministry of health and medical education of Iran.
We conducted this single center double blind randomized study
between May, 2013 and August, 2014 at Shohada-e-Tajrish hospital in Tehran (Iran).
In total, 52 patients were randomized into two groups: 26 participants to drug and 26 participants to placebo group. Randomization was accomplished by computer using dynamic allocation with an established algorithm that balances the marginal distribution. Fatigue was measured using a Visual Analogue Fatigue Scale (VAFS) and Fatigue Severity Scale.
Inclusion criteria: age more than 18, having the diagnosis of a solid malignancy, Karnofsky Performance Status more than 70, serum hemoglobin level of more than 8g/dL, serum total bilirubin less than 2mg/dL, serum creatinine less than 2mg/dL.
Intervention: Case group (26 patients) received processed honey and royal jelly, while the control group received pure honey (without royal jelly). Both groups were instructed to consume their supplement 5mL twice daily for 4 weeks. Both groups were assessd at the beginning of study, after 2 weeks, and then at the end of 4 weeks of treatment.
main outcome measures: The primary outcome: changes in the fatigue severity scales
