Abstract:
Voriconazole-induced periostitis (VIP) is an uncommon side effect typically seen in immunosuppressed patients requiring prolonged antifungal therapy. These patients can present with bone pain, fragility, and elevated alkaline phosphatase (ALP). We present a case of VIP in a 72-year-old immunocompromised female on antifungal therapy presenting with a comminuted intertrochanteric fracture after a ground-level fall. VIP, although rare, should be included as a differential diagnosis for patients presenting with bone pain and/or fractures with radiographic features of periostitis. This is particularly true when there is a history of or prior imaging suggesting a solid organ transplant. In these cases, a dedicated review of current medications noting long-term voriconazole use in the absence of underlying rheumatologic disease can result in a confident diagnosis.
Insights
Voriconazole-induced periostitis (VIP) is a rare side effect causing bone pain and fractures in immunocompromised patients. Consider VIP in patients with a history of organ transplant and long-term voriconazole use.
Area of Science:
- Pharmacology
- Orthopedics
- Rheumatology
Background:
- Voriconazole-induced periostitis (VIP) is an uncommon adverse effect of prolonged voriconazole therapy.
- It primarily affects immunosuppressed patients, often those with a history of solid organ transplantation.
- Clinical manifestations include bone pain, fragility, and elevated alkaline phosphatase (ALP).
Observation:
- A 72-year-old immunocompromised female presented with a comminuted intertrochanteric fracture after a ground-level fall.
- The patient was undergoing long-term antifungal therapy with voriconazole.
- Radiographic features suggested periostitis, prompting consideration of VIP.
Findings:
- Voriconazole-induced periostitis (VIP) should be considered in the differential diagnosis for patients presenting with bone pain and/or fractures.
- Radiographic findings of periostitis in conjunction with a history of organ transplant and long-term voriconazole use are key indicators.
- Diagnosis is confirmed by excluding underlying rheumatologic diseases and reviewing medication history.
Implications:
- Early recognition of VIP can prevent misdiagnosis and inappropriate treatment for fractures.
- Awareness among clinicians is crucial for managing patients on long-term voriconazole therapy.
- This case highlights the importance of a thorough medication review in patients with unexplained bone pathology.
