Rambod, M., Pasyar, N., & Ramzi, M. (2018). The effect of zinc sulfate on prevention, incidence, and severity of mucositis in leukemia patients undergoing chemotherapy. European Journal of Oncology Nursing, 33, 14–21.
The purpose of the study was to evaluate the effect of zinc sulfate on the incidence and severity of mucositis in patients with leukemia undergoing chemotherapy.
This is a randomized, placebo-controlled, triple-blinded study conducted on patients with leukemia undergoing chemotherapy. The subjects were randomized into an experimental arm where they received zinc sulfate (50 mg) three times daily for 14 days from the first day of chemotherapy; the control group received placebo capsules three times per day. Mucositis was measured by the Oral Mucositis Index and World Health Organization mucositis scale on the 4th, 7th, and 14th day after chemotherapy.

This is a randomized clinical trial and placebo-controlled study for patients undergoing chemotherapy for leukemia. Patients were randomly assigned to receive either zinc sulfate or placebo.
There is significant difference in the incidence of mucositis during the 14 days of the study, 9 patients (25%) in the experimental group (zinc sulfate) and 19 (54%) in the control group (placebo) showed incidence of mucositis was 2.1 times higher in the control group. Onset of mucositis occurred on days 5.83 (SD = 3.37) (zinc sulfate) and 4.58 (SD = 2.47) (placebo), t test showed no difference between these two groups regarding the onset of mucositis (t = 0.95, p = 34). There is no confirmation of mucositis occurring later in the zinc sulfate group in comparison to the control group. The severity of mucositis was milder in the experimental group compared to the control group on 4th, 7th, and 14th day. RM-ANOVA indicated significant difference between mean score objective evaluation of mucositis the two groups (F = 7.83, p = 0.07). Results also showed significant difference between the two groups' mean score of subjective evaluation of mucositis (F = 5.79, p = 0.01)
The results of the study show that zinc sulfate is helpful in preventing mucositis in patients with leukemia undergoing chemotherapy. The current study does not support any significant difference between the two group in delaying onset of mucositis. The severity of mucositis was milder in the zinc sulfate group in comparison to the control group.
Using zinc sulfate at the dose of 50 mg three times per day for 14 days helped to prevent and decrease the severity of mucositis in the leukemia population undergoing chemotherapy. This along with standard of care oral hygiene could be an effective treatment to prevent and decrease the severity of mucositis. Additional research is needed.
