Low amounts of winter sunshine are associated with increased tuberculous meningitis incidence

Key Point: This study found a significant association between the monthly tuberculous meningitis incidence rate (a severe extrapulmonary complication of TB) and the number of sunshine hours 3 months earlier–possibly implicating vitamin D deficiency.

Tuberculous meningitis (TBM) is a severe extrapulmonary complication of tuberculosis occurring mainly in early childhood, and developing within a few months after the primary infection. A recently published study is believed to be the first to examine the role of sunshine hours—and possibly vitamin D—in the pathophysiology of tuberculosis meningitis (TBM).

Vitamin D deficiency is associated strongly with Myobacterium tuberculosis (M. tuberculosis) disease. During the winter months, when UVB radiation intensity declines, the decrease can lead to...
