Chronic Hepatitis B is NOT an Absolute Contraindication for Secukinumab
Secukinumab can be used in patients with chronic hepatitis B, including those on nivolumab with severe psoriasis, but requires mandatory hepatitis B screening, risk stratification, antiviral prophylaxis for HBsAg-positive patients, and close monitoring for viral reactivation. 1
Risk Stratification and Management Algorithm
Pre-Treatment Assessment Required
- Screen all patients with hepatitis B surface antigen (HBsAg), anti-HBs antibody, anti-HBc antibody, and baseline HBV-DNA PCR before initiating secukinumab 1
- Obtain baseline liver function tests (complete metabolic panel) 1
- Consult with hepatology or infectious disease specialist for patients with active or chronic HBV infection 1
Treatment Decisions Based on HBV Status
For HBsAg-Positive Patients (Chronic Active HBV):
- Initiate antiviral prophylaxis (entecavir or tenofovir) before starting secukinumab 2, 3
- This represents a relative contraindication requiring specialist management, not an absolute contraindication 1
- HBV reactivation risk is 24% without prophylaxis but 0% with prophylaxis 3
- Continue antiviral therapy throughout secukinumab treatment 2, 3
For HBsAg-Negative/Anti-HBc-Positive Patients (Resolved or Occult HBV):
- Reactivation risk is lower (4.17%) but still present 3
- Monitor HBV-DNA PCR every 3 months without mandatory prophylaxis 2, 4
- Consider prophylaxis if additional immunosuppression (like nivolumab) is present 2, 3
For Patients with Resolved HBV Infection (Anti-HBc positive only):
- Do not require specialist follow-up but need monitoring for reactivation risk 1
- Serial HBV-DNA PCR monitoring every 3 months is essential 4, 5
Secukinumab-Specific Safety Profile in HBV
The evidence strongly supports secukinumab's favorable safety profile compared to other biologics:
- Real-world data from 60 patients showed only 1/60 (1.7%) hepatitis reactivation over 53.5 weeks, occurring in a patient who did not receive prophylaxis 2
- Secukinumab carries no increased risk for reactivation of hepatitis B compared to TNF-α inhibitors, which have higher reactivation rates 6
- In a Chinese cohort of 20 patients (including chronic inactive, occult, and resolved HBV), no viral reactivation occurred over 24 weeks with appropriate monitoring 5
- IL-17 inhibitors like secukinumab are less likely to cause hepatitis reactivation than anti-TNF therapies 2, 6
Ongoing Monitoring Protocol
- HBV-DNA PCR testing every 3 months during secukinumab therapy 2, 4, 5
- Liver function tests (ALT, AST) every 3 months 5, 3
- Monitor for clinical signs of hepatitis (fatigue, jaundice, right upper quadrant pain) 5, 3
- HBsAg can remain negative even with viral reactivation, making HBV-DNA PCR essential 4, 3
Critical Pitfalls to Avoid
- Never start secukinumab in HBsAg-positive patients without antiviral prophylaxis - this increases reactivation risk from 0% to 24% 3
- Do not rely solely on HBsAg testing - reactivation can occur with negative HBsAg but positive HBV-DNA PCR 4, 3
- Avoid skipping the 3-month monitoring intervals - early detection of viral reactivation allows prompt antiviral intervention 2, 4, 5
- Do not assume resolved HBV infection is risk-free - these patients still require HBV-DNA monitoring as reactivation can occur 1, 4, 5
Special Consideration for Cancer Patients on Nivolumab
While the guidelines do not specifically address the combination of secukinumab with checkpoint inhibitors like nivolumab, the general principle applies: multiple immunosuppressive agents increase infection and reactivation risk 2, 3. In this high-risk scenario:
