Hi. If you are not symptomatic,  forget about everything. If you are still symptomatic,  ideally RUT for H pylori should have been repeated as there is high resistance to antibiotics in H pylori in Indian scenario. If still positive, needs second line treatment or bismuth based H pylori eradication therapy. The whitish spots in duodenum is called lymphangiectasia. Like blood's vascular system, there is a lymphatic system in body which when blocked causes its tiny branches to erupt on to the duodenal mucosa causing whitish sopts. There are 100s of reasons to have that, again if you are asymptomatic then the finding doesn't carry any weightage.
