Abstract
Zinc (Zn) is nutritionally essential trace element, and thus deficiency may severely affect human health. The results of cross-sectional studies indicate that micronutrient deficiencies are common in patients with tuberculosis. Our goal is to investigate whether Zn supplementation can increase the effects of anti-TB treatment or not. Patients with newly diagnosed tuberculosis were divided in to 2 groups. One group (n= 37) received capsule contains 50 mg of elemental zinc (as zinc sulfate) for 6 months every other day (micronutrient group) and Group II (n= 37) received placebo. Both groups received the same anti-tuberculosis treatment recommended by the WHO. Clinical examination, BMI, chest X-ray, direct sputum examination, assessment of serum zinc levels (by atomic absorption spectrophotometry), and biochemical markers serum concentration (by using an RA1000 AutoAnalyzer) were carried out before and after 2- and 6-months anti-tuberculosis treatment. Plasma zinc concentrations in the micronutrient group was higher than placebo group After treatment. In the placebo group increasing in SGOT and SGPT concentrations were significantly higher than micronutrient group after 2 months of treatment (p< 0.05). The significant changes (p< 0.05) were observed on the serum levels of total protein, albumin. Alkaline phosphatase (ALP) levels, serum creatinine, uric acid and urea in groups were not significantly different. Zinc supplementation results in earlier sputum smear conversion in the micronutrient group during the first 6 weeks. Increased body weight and serum zinc and serum albumin and decrease in total protein was observed in the micronutrient group.
Highlights
Tuberculosis (TB) defined as an illness that occur via Mycobacterium tuberculosis in which different organs are involved such as lungs, kidneys, and bones
In order to treatment of TB used of multi drugs therapy, these drugs have several side effects include, hepatoxicity, nephrotoxicity, harm effects on the bones, malnutrition, and etc. In the former studies it has been reported that TB infection causes a decrease in serum concentrations of Zn and albumin in men beings experimental animals [16]
We assessed the serum concentration of Zn in patients with TB infection that intake Zn supplement compared to placebo group after 2 and 6 months
