The paper reviews the information available concerning the mutagenic, teratogenic and carcinogenic effects of antimony. A claim that antimony compounds could have mutagenic properties is based on insufficient and not particularly relevant data. Additional experiments, particularly with organic antimony compounds...

We show that increased plasma superoxide dismutase 1 (SOD1) levels are statistically significant predictors of the failure of pentavalent antimony treatment for cutaneous leishmaniasis caused by Leishmania braziliensis. In Leishmania amazonensis-infected patients, host SOD1 levels can be used to discriminate...
