Abstract:
Steroid myopathy is a non-inflammatory toxic myopathy that occurs as side effect of exogenous and endogenous glucocorticoid excess. The purpose of this review is to examine issues that limit our understanding of this myopathy with respect to nosology, etiopathogenesis, conditioning factors, and muscle fiber selectivity. We suggest that if more data were available on these issues, the understanding of steroid myopathy would be enhanced substantially, thus allowing an early detection of its occurrence (before the appearance of clinical or laboratory signs) and a proper treatment of the patients.
Insights
Steroid myopathy, a toxic condition from excess glucocorticoids, requires more research. Understanding its causes and effects can lead to earlier detection and better treatment for patients.
Area of Science:
- Endocrinology
- Neurology
- Muscle Physiology
Background:
- Steroid myopathy is a toxic, non-inflammatory condition resulting from glucocorticoid excess.
- It presents as a side effect of both externally administered and internally produced glucocorticoids.
Purpose of the Study:
- To review and identify limitations in understanding steroid myopathy.
- Focus areas include nosology, etiopathogenesis, conditioning factors, and muscle fiber selectivity.
Main Methods:
- This study is a review of existing literature.
- It synthesizes current knowledge and identifies gaps in understanding steroid myopathy.
Main Results:
- Current understanding of steroid myopathy is limited by data gaps.
- Specific areas needing more research include classification, cause, contributing factors, and which muscle fibers are affected.
Conclusions:
- Further research into the identified issues is crucial.
- Enhanced understanding will enable earlier detection, potentially before clinical signs, and improved patient treatment.

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups.
