Medication use and multiple myeloma risk in Los Angeles County.

ABSTRACT:

Background

The role of medication use in multiple myeloma (MM) risk remains unclear.

Methods

The Los Angeles County Multiple Myeloma Case-Control Study, comprising 278 MM cases and individually matched neighborhood controls, provided data to assess associations between medication use and MM risk. Odds ratios (OR) and 95 % confidence intervals (CI) were estimated using conditional logistic regression.

Results

Erythromycin (ever) use was associated with increased MM risk (OR 1.85, 95 % CI 1.13-3.03). This association was restricted to men (OR 3.77, 95 % CI 1.72-8.29) and was especially apparent among men who took two or more courses of erythromycin (OR 4.68, 95 % CI 1.70-12.87).

Conclusions

Compared to females, males have lower levels of cytochrome P450 3A4 (CYP3
