Abstract Objective: In 150 hypercholesterolemic patients, unable to tolerate ?1 statin because of myositis-myalgia, selected by low (<32?ng/ml) serum 25 (OH) vitamin D, we prospectively assessed whether vitamin D supplementation with resolution of vitamin D deficiency would result in statin tolerance, free of myositis-myalgia.
Research design and methods: We studied 74 men, 76 women, median age 60, 131 white, 17 black and 2 other. On no statins, 50,000 units of vitamin D was given twice a week for 3 weeks, and then continued once a week. After 3 weeks on vitamin D, statins were restarted. Patients were re-assessed on statins and vitamin D every 3 to 4 months, with serial measures of serum 25 (OH) vitamin D, creatine phosphokinase (CPK), LDL cholesterol (LDLC) and assessment of myositis-myalgia.
Main outcome measures: Percentage of patients myalgia-free on vitamin D plus reinstituted statins, serum 25 (OH) vitamin D, CPK, and LDLC on reinstituted statins and concurrent vitamin D supplementation.
Results: On vitamin D supplementation plus re-instituted statins for a median of 8.1 months, 131 of the 150 patients (87%) were free of myositis-myalgia and tolerated the statins well. Serum 25 (OH) vitamin D increased from median 21 to 40?ng/ml (p?<?0.001), and normalized (?32?ng/ml) in 117 (78%) of 150 previously vitamin D deficient, statin-intolerant patients. Median LDLC decreased from 146?mg/dl to 95?mg/dl, p?<?0.001.
Conclusion: Symptomatic myositis-myalgia in hypercholesterolemic statin-treated patients with concurrent serum 25 (OH) vitamin D deficiency may reflect a reversible interaction between vitamin D deficiency and statins on skeletal muscle causing myalgia.
