From the Guidelines
Steroid toxicity can have severe and long-lasting effects on patients, and it is crucial to monitor and manage these effects carefully to minimize harm, as highlighted in the 2021 ASCO guideline update 1.
Key Considerations
- Patients on long-term corticosteroid therapy should undergo regular clinical and laboratory assessments to detect potential toxicities early.
- The lowest possible dose of steroids should be used for the shortest possible duration to minimize the risk of steroid-related toxicities, as emphasized in the 2021 study 1.
- Certain patient populations, such as those with pre-existing conditions like diabetes mellitus or an immune-compromised status, and the elderly, require special attention and careful monitoring due to their increased vulnerability to steroid toxicity.
Monitoring and Management
- Regular blood pressure checks, weight monitoring, and screening for symptoms of hyperglycemia, mood changes, sleep disturbances, and muscle weakness are essential for patients on long-term corticosteroid therapy.
- Laboratory evaluation should include fasting glucose or HbA1c every 3-6 months, electrolytes, and lipid profiles annually, as well as bone mineral density testing at baseline and every 1-2 years for patients on prolonged therapy.
- For patients on high-dose steroids (>20mg prednisone daily), more frequent monitoring of glucose levels and blood pressure is warranted, and ophthalmologic evaluation for cataracts and glaucoma should be performed annually.
- Adrenal function testing may be necessary when tapering steroids after prolonged use, and alternative therapies or preventive measures like calcium/vitamin D supplementation for bone health or proton pump inhibitors for gastrointestinal protection should be considered.
Prevention and Mitigation
- The use of prophylactic agents to prevent certain opportunistic infections and preemptive measures to mitigate various toxicities is necessary for patients needing longer-term steroid use, as recommended in the 2021 ASCO guideline update 1.
- A multidisciplinary approach may be used in the management of certain steroid-related complications, and institutional guidelines should be considered in decision-making.
- The combination regimen with azathioprine is associated with a lower occurrence of corticosteroid-related adverse events, and switching to budesonide or applying higher doses of azathioprine may be considered in patients presenting with steroid side effects, as suggested in the 2015 EASL clinical practice guidelines 1.

From the Research
Effects of Steroid Toxicity
The effects of steroid toxicity can be severe and varied. Some of the common effects include:
- Bone marrow depression, hemorrhagic cystitis, hair loss, infertility, and oncogenesis, as reported in a study on the treatment of nephrotic syndrome 3
- Psychosis, including hallucinations and delusions, as seen in a case report of a 12-year-old patient with discoid-type lupus erythematosus 4
- Weight gain, osteoporosis, cataracts, hypertension, diabetes mellitus, dyspepsia, and psychiatric complaints, as detected in an audit of patients on long-term oral corticosteroids 5
- Exacerbation of preexisting conditions or presentation of new medical conditions, as noted in a review of the pharmacology and complications of steroids 6
- Neuropsychiatric toxicity, including insomnia, cognitive impairment, mood symptoms, mania, psychosis, and severe depression, as reported in a systematic review of steroid-induced mental disorders in cancer patients 7
Specific Effects on Different Populations
The effects of steroid toxicity can vary depending on the population being treated. For example:
- In children, steroid-induced psychosis is a rare but serious adverse side effect, as reported in a systematic review of the literature 4
- In patients with cancer, steroid-induced mental disorders can be a significant complication of treatment, as noted in a systematic review of the current evidence 7
- In patients on long-term oral corticosteroids, monitoring for adverse effects is crucial to prevent and detect potential complications, as emphasized in a study on monitoring long-term oral corticosteroids 5
Common Adverse Effects
Some of the common adverse effects of steroid toxicity include:
- Weight gain, as reported in a study on monitoring long-term oral corticosteroids 5
- Osteoporosis, as detected in an audit of patients on long-term oral corticosteroids 5
- Cataracts, as reported in a study on monitoring long-term oral corticosteroids 5
- Hypertension, as noted in a review of the pharmacology and complications of steroids 6
- Diabetes mellitus, as detected in an audit of patients on long-term oral corticosteroids 5
