DPP-4 Inhibitor Gene ID antidepressants and CYP Metabolic Status For many on the antidepressants investigated, we regularly discovered that the interaction of diabetes status and CYP2D6 and CYP2C19 metabolic phenotype is statistically significant (Supplementary Figure S2). Exactly where this was the case, we stratified our analyses by regardless of whether participants had diabetes or not. We observed this interaction for fluoxetine, venlafaxine, citalopram, sertraline, and amitriptyline, and for tricyclic antidepressants as a class. Amongst all participants (irrespective of diabetes status) taking paroxetine (SSRI), we observe considerably greater HbA1c levels amongst CPY2D6 poor metabolizers (mean difference: two.43 mmol/mol; 95 CI (1.23,3.63); p = 7.77 10-5 ) (see Table 2, Figure two, and Supplementary Table S10). A stratified analysis of diabetic participants taking fluoxetine (SSRI) reveals a suggestive association between CYP2D6 intermediate metabolizers and reduced HbA1c levels in comparison to typical metabolizers (mean difference = -3.74 mmol/mol; 95 CI [-6.82, -0.67]; p = 0.017 (see Tables three and 4, Figure two, and Supplementary Table S11).
