Background: Steroid-induced osteonecrosis is unpredictable and highly morbid.
Methods: MEDLINE (Ovid) and PubMed search for relevant literature.
Results: Oral steroid doses typically considered to be associated with the condition are >20 mg of prednisone (or equivalent) per day or >2 g within a period of 2 to 3 months. Symptoms may be vague.
Conclusions: Dermatologists must exercise a high degree of clinical suspicion and warn patients about steroid-related risks and conditions for follow-up.

Background: Steroid-induced osteonecrosis of the femoral head (SIONFH) is a universal hip articular disease and is very hard to perceive at an early stage. The understanding of the pathogenesis of SIONFH is still limited, and the identification of efficient diagnostic biomarkers is insufficient. This research aims to recognize and validate the latent exosome-related molecular signature in SIONFH diagnosis by employing bioinformatics to investigate exosome-related mechanisms in SIONFH.

Background: Glucocorticoids (GCs) are critical regulatory molecules in the body, commonly utilized in clinical practice for their potent anti-inflammatory and immunosuppressive properties. However, prolonged, high-dose GC therapy is frequently associated with femoral head necrosis, a condition known as glucocorticoid-induced osteonecrosis of the femoral head (GC-ONFH). Emerging evidence suggests that enhanced autophagy may mitigate apoptosis, thereby protecting osteoblasts from GC-induced damage and delaying the progression of ONFH.

Bone metastasis and steroids are known to activate the coagulation system and induce osteoporosis, pathological bone fractures, and bone pain. Heparanase is a protein known to enhance the hemostatic system and to promote angiogenesis, metastasis, and inflammation. The objective of the present study was to evaluate the effects of steroids and malignancy on the coagulation factors and osteoblast activity in the bone tissue.

Steroid-induced osteonecrosis of the femoral head (SANFH) is a common hip joint disease that imposes a heavy economic burden on society. Patients continue to experience bone necrosis even after discontinuing glucocorticoid therapy, and the specific mechanisms require further investigation. The results of this study demonstrate that exosomes secreted by damaged vascular endothelial cells in SANFH lesions may be a crucial factor leading to abnormal adipogenic differentiation of bone marrow stromal cells (BMSCs).

Background: Zinc-finger E-box-binding homeobox-1 (ZEB1) is predominantly found in type-H vessels. However, the roles of ZEB1 and type-H vessels in steroid-induced osteonecrosis of the femoral head (SONFH) are unclear.
Methods: Human femoral heads were collected to detect the expression of ZEB1 and the levels of type-H vessels.
