Corticosteroid complications in respiratory disease

Area of Science:

• Pulmonology
• Endocrinology
• Ophthalmology
• Orthopedics

Background:

• Corticosteroids are widely used for managing asthma and chronic pulmonary diseases.
• Prolonged corticosteroid therapy is associated with potential adverse effects.
• Understanding the specific complications and their correlation with dosage is crucial for patient management.

Purpose of the Study:

• To compare the prevalence of complications in patients on long-term corticosteroids versus a control group.
• To identify specific types of complications associated with prolonged corticosteroid use.
• To investigate the relationship between corticosteroid dosage and the severity of ocular and skeletal complications.

Main Methods:

• Retrospective study comparing 51 patients on corticosteroids for >1 year with 31 never-exposed control patients.
• Assessment of Cushingoid features, ocular complications (cataracts, glaucoma), and skeletal complications (vertebral fractures, aseptic necrosis, osteopenia).
• Multiple regression analysis to determine the correlation between total lifetime corticosteroid dosage and serious ocular/skeletal complications.

Main Results:

• Significantly higher prevalence of Cushingoid features (P<.005), ocular complications (P<.025), and skeletal complications (P<.005) in the corticosteroid group.
• Overall complication rate was significantly higher in patients receiving corticosteroids (P<.005).
• Serious ocular and skeletal complications showed a direct proportionality to the total lifetime dosage of corticosteroids.

Conclusions:

• Long-term corticosteroid therapy for chronic pulmonary diseases is linked to a significantly increased risk of systemic complications.
• The severity of ocular and skeletal adverse effects is dose-dependent.
• These findings underscore the need for strategies to minimize corticosteroid toxicity and reduce complications.
