Study Notes
Patient Overview
- Sara is a 30-year-old female diagnosed with systemic lupus erythematosus (SLE) for two years.
- Current weight is 60 kg.
- Recent urinalysis shows significant proteinuria, and a kidney biopsy confirms class IV lupus nephritis.
- Initiated treatment with pulse glucocorticoid therapy followed by oral prednisone.
Treatment Strategy
- Transitioned to maintenance therapy after achieving remission with immunosuppressants.
Management Plan
Mild Activity
- Symptoms include polyarthralgia, small joint mono-oligoarthritis, and limited skin lesions.
- Treatment: Prednisone (PDN) 2.5-7.5 mg/day.
- Taper down over 1-2 weeks to a maintenance dose of 2.5 mg/day.
- If no improvement, re-evaluate for moderate disease activity.
- If improvement occurs, add hydroxychloroquine (HCQ) 200 mg/day alongside PDN 2.5 mg/day.
Moderate Activity
- Symptoms include polyarthritis, moderate thrombocytopenia (20,000–50,000/mm³), hemolytic anemia with low hemolysis rate, widespread skin lesions, nonsevere pericardial effusion/pericarditis, and pleural effusion.
- Treatment: Methylprednisolone (MP) at 125-250 mg/day for 3 days, followed by PDN 5-10 mg/day and an immunosuppressant.
- Taper down PDN over 1-2 weeks to 2.5-5 mg/day.
- If no improvement after initial treatment, repeat MP in 2-4 weeks.
- If improvement is noted, prescribe HCQ 200 mg/day, PDN 2.5-5 mg/day, and continue immunosuppressant.
Severe Activity
- Symptoms may include lupus nephritis, pneumonitis, or severe thrombocytopenia.
- Management for severe cases requires careful adjustment of glucocorticoids and immunosuppressants based on response to treatment.
Summary
- Treatment focuses on both glucocorticoids and immunosuppressants, adjusted based on disease activity levels.
- Regular monitoring and reevaluation are essential to successfully manage SLE and associated complications.
Overview of Oral Corticosteroids in Severe Asthma
- Systemic corticosteroids are essential for managing severe asthma, used for exacerbations and as chronic maintenance therapy.
- Chronic use can lead to significant systemic side effects: osteoporosis, cardiovascular issues, diabetes, and obesity.
- Long-term corticosteroids can inhibit adrenal gland's cortisol production, leading to adrenal insufficiency.
- The risk of side effects increases with cumulative dosage over time.
Advances in Treatment
- New biologic treatments for severe asthma have emerged, improving clinical outcomes and reducing dependence on oral corticosteroids.
- These treatments allow many patients to reduce or eliminate oral corticosteroid use altogether.
- The PONENTE Study provides evidence-based guidance for tapering oral corticosteroids in patients transitioning to biologics.
Tapering Protocol
- Tapering guidance is aimed at patients currently on chronic oral corticosteroid therapy and have started biologic treatment.
- Begins four weeks after initiating biologic therapy.
Dosage Reduction Strategy
- For patients on prednisone/prednisolone dosage > 20 mg/day:
- Reduce by 5 mg/day weekly until reaching 20 mg/day.
- For dosage > 10 to ≤ 20 mg/day:
- Reduce by 5 mg/day every 2 weeks after reaching 20 mg/day.
- For dosage > 7.5 to ≤ 10 mg/day:
- Reduce by 2.5 mg/day every 2 weeks after reaching 10 mg/day.
- For dosage > 5 to ≤ 7.5 mg/day:
- Reduce by 2.5 mg/day every 4 weeks after reaching 7.5 mg/day.
- Stabilize at 5 mg/day for 4 weeks before evaluating cortisol levels.
Cortisol Evaluation
- Morning cortisol levels should be assessed between 8:00 – 9:00 AM when reaching a prednisone dose of 5 mg/day.
- Normal cortisol levels are > 350 nmol/L; indeterminate levels are defined, and complete adrenal insufficiency (AI) occurs at 450 nmol/L.
Conclusion
- The tapering protocol aims to safely reduce oral corticosteroid doses in severe asthma patients starting biologics while monitoring for adrenal insufficiency.
