Vertebral abnormalities associated with synthetic retinoid use.

L H Gerber, R K Helfgott, E G Gross

    Journal of the American Academy of Dermatology
    |May 1, 1984
    PubMed
    Summary

    Synthetic retinoids like isotretinoin may increase the risk of spinal abnormalities, particularly in patients with basal cell nevus syndrome or basal cell carcinoma. Further research is needed to confirm these findings for spinal health.

    Area of Science:

    • Dermatology
    • Rheumatology
    • Radiology

    Background:

    • Synthetic retinoids, including isotretinoin and etretinate, are used to treat various skin disorders.
    • Concerns exist regarding potential side effects on skeletal structures, specifically the vertebral spine.

    Purpose of the Study:

    • To investigate the association between long-term synthetic retinoid use and the development of vertebral spine abnormalities.
    • To compare radiographic findings in patients treated with retinoids versus matched untreated controls.

    Main Methods:

    • Radiographic examination of the vertebral spine in 50 patients treated with retinoids for at least 2 years.
    • Comparison with 72 age- and sex-matched untreated patients.
    • Analysis focused on anterior spinal ligament calcification and osteophyte formation.

    Main Results:

    • No significant differences in spinal abnormalities were found when comparing the entire retinoid-treated group with the untreated group.
    • However, patients with basal cell nevus syndrome (BCNS) or basal cell carcinoma (BCC) who received isotretinoin showed a significantly higher frequency of spinal abnormalities (P < 0.01) compared to untreated controls.
    • This suggests a potential link between isotretinoin and ossifying diathesis in specific patient populations.

    Conclusions:

    • Long-term isotretinoin use may be associated with an increased risk of ossifying diathesis in patients with BCNS or BCC.
    • Further investigation is warranted to elucidate the specific mechanisms and clinical implications of this association.
