Albendazole treatment had no effect among participants without any or only a single species helminth infection measured (hookworm [Ancylostoma duodenale, Necator americanus]; A. lumbricoides; T. trichiura; Strongyloides stercoralis), but resulted in high homeostatic model of insulin resistance, a measure of insulin resistance, in the presence of multiple species infection at baseline. This evidence concerns the gene INS and helminthiasis.
