In the present study, researchers wanted to know if patients admitted to the hospital for tuberculosis in Kampala, the capital city of Uganda, were vitamin D deficient or not.
They measured vitamin D levels among other things in 260 consecutively admitted tuberculosis patients. They found vitamin D deficiency was common, despite Uganda close proximity to the equator and having an abundance of sunshine.
…The researchers also noticed that vitamin D deficiency was more common in patients with HIV co-infection, low CD4 cell counts (a type of cell that helps your immune system) and anemia.
What’s the bigger problem: vitamin D deficiency or HIV-positivity?
