| アブストラクト | BACKGROUND: Bullous pemphigoid (BP) is a serious autoimmune skin disease affecting older people. Given the highly prevalent polypharmacy in older people, identifying drug combinations associated with high BP risk is needed. OBJECTIVES: To identify drug combinations frequently prescribed for older people prior to BP using association rule mining (ARM) and estimate their BP risk. METHODS: We conducted a nested case-control study using UK Clinical Practice Research Datalink primary care records (1998-2021). ARM identified the ten most common drug class or active substance pairs more likely co-prescribed (lift) on the same day and within 30 days of one another (sensitivity analysis). Fold change (FC; case:control lift ratio) identified combinations with greater lift in cases. Multivariable conditional logistic regression estimated BP risk following combinations and their constituent drugs. RESULTS: Among 16844 cases and 79493 controls, most frequent drug class combinations associated with increased BP risk with greater lift in cases were: ACE inhibitors (ACEIs)-statins (FC: 1.31 vs FC, sensitivity analysis: 1.18); antiplatelets-statins (1.23 vs 1.11); proton pump inhibitors (PPIs)-antiplatelets (1.22 vs 1.14); PPIs-statins (1.22 vs 1.14), and ACEIs-antiplatelets (1.20 vs 1.09). Substance combinations with a greater lift in cases included simvastatin-ramipril (1.30), aspirin-simvastatin (1.21), aspirin-ramipril (1.19), and aspirin-bendroflumethiazide (1.16). The sensitivity analysis results for substances were similar. BP risk following drug combinations was lower than after single drugs. CONCLUSIONS: ARM found that most frequently prescribed drug combinations associated with increased BP risk treated cardiovascular diseases and hypertension. Patients should be vigilant for skin changes following these drugs rather than avoid them. |
