Summary

The purpose of this study was to investigate if adjuvant treatment with arginine (the substrate for nitric oxide production) rich food supplements could improve clinical outcome in patients with smear positive tuberculosis by affecting nitric oxide production.

Detailed description

Tuberculosis (TB) is disease of increased global public health importance. Because of emerging multi drug resistance and the long treatment duration there is a need to optimize the current chemotherapy. Host immunity is important in determining the susceptibility and outcome of disease as could be exemplified by co infection with HIV which dramatically increases the risk to develop TB. Previous results from our group and others show that nitric oxide produced by activated macrophages from arginine might be important to control the disease. However, the relative importance of nitric oxide in human TB has been debated. In a previous study in Gondar, Ethiopia, we observed an effect of adjuvant treatment with arginine capsules on sputum smear conversion and reduction of cough. In this study we wanted to test the hypothesis based on previous observations that an arginine rich food supplementation might enhance clinical improvement in patients with smear positive tuberculosis and if this effect could be due to increased nitric oxide production.

Conditions

• Tuberculosis
• HIV

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Peanuts	30g of peanuts daily for 4 weeks (directly observed). This dose of peanuts is equivalent to 1 gram of arginine.
DIETARY_SUPPLEMENT	Daboqolo	30g of Daboqolo per os daily for 4 weeks (given supervised). 30g of Daboqolo is equivalent to 0.1 g of arginine.
