Genetically‐Proxied Levels of Vitamin D and Risk of Intracerebral Hemorrhage
BACKGROUND: The evidence linking vitamin D (VitD) levels and spontaneous intracerebral hemorrhage (ICH) remains inconclusive. We tested the hypothesis that lower genetically determined VitD levels are associated with higher risk of ICH. METHODS AND RESULTS: We conducted a 2 sample Mendelian Randomiz...

description | BACKGROUND: The evidence linking vitamin D (VitD) levels and spontaneous intracerebral hemorrhage (ICH) remains inconclusive. We tested the hypothesis that lower genetically determined VitD levels are associated with higher risk of ICH. METHODS AND RESULTS: We conducted a 2 sample Mendelian Randomization (MR) study using publicly available summary statistics from published genome‐wide association studies of VitD levels (417 580 study participants) and ICH (1545 ICH cases and 1481 matched controls). We used the inverse‐variance weighted approach to generate causal estimates and the MR Pleiotropy Residual Sum and Outlier and MR‐Egger approaches to assess for horizontal pleiotropy. To account for known differences in their underlying mechanism, we implemented stratified analysis based on the location of the hemorrhage within the brain (lobar or nonlobar). Our primary analysis indicated that each SD decrease in genetically instrumented VitD levels was associated with a 60% increased risk of ICH (odds ratio [OR], 1.60; [95% CI, 1.05–2.43]; P=0.029). We found no evidence of horizontal pleiotropy (MR‐Egger intercept and MR Pleiotropy Residual Sum and Outlier global test with P>0.05). Stratified analyses indicated that the association was stronger for nonlobar ICH (OR, 1.87; [95% CI, 1.18–2.97]; P=0.007) compared with lobar ICH (OR, 1.43; [95% CI, 0.86–2.38]; P=0.17). CONCLUSIONS: Lower levels of genetically proxied VitD levels are associated with higher ICH risk. These results provide evidence for a causal role of VitD metabolism in ICH. |
