Insights
Antiphospholipid antibodies (aPLs) were found in 12.6% of hepatitis B virus (HBV)-infected patients, primarily as IgM anticardiolipin antibodies (aCL Ab). Most aPLs persisted for 12 weeks, showing a weak association with Antiphospholipid Syndrome (APS) clinical manifestations.
Area of Science:
- Immunology
- Hepatology
- Infectious Diseases
Background:
- Infections are frequently linked to antiphospholipid antibodies (aPLs).
- Hepatitis B virus (HBV) infection is a common global health concern.
Purpose of the Study:
- To determine the prevalence, persistence, clinical significance, and characteristics of aPLs in HBV-infected patients.
- To investigate the association between aPLs and clinical manifestations in HBV infection.
Main Methods:
- Assessed anticardiolipin antibodies (aCL Ab), anti-β(2)-glycoprotein I antibodies (β(2)GPI Ab), and lupus anticoagulant (LA) in 143 HBV patients and 32 controls.
- Follow-up specimens were collected from patients with elevated aPL levels.
Main Results:
- A total of 12.6% of HBV patients tested positive for aPLs, predominantly IgM aCL Ab.
- Persistent aPLs were observed in 71.4% of patients over a 12-week period.
- No significant clinical manifestations related to aPLs were identified in the study cohort.
Conclusions:
- IgM aCL Ab were the most common aPLs in HBV infection, with a weak link to Antiphospholipid Syndrome (APS) clinical features.
- Unlike transient aPLs in other infections, aPLs in HBV patients demonstrated persistent detection over 12 weeks.
- The findings highlight the distinct profile of aPLs in HBV infection, emphasizing their persistence rather than transient presence.
Background:
Many infections are associated with antiphospholipid antibodies (aPLs). The purpose of this study was to investigate the prevalence, persistence, clinical significance, and characteristics of aPLs in hepatitis B virus (HBV)-infected patients.
Methods:
This study included 143 patients with HBV infection and 32 healthy individuals as controls. The presence of anticardiolipin antibodies (aCL Ab), anti-β(2)-glycoprotein I antibodies (β(2)GPI Ab), and lupus anticoagulant (LA) was assessed.
Results:
The total prevalence of aPLs in HBV-infected patients was 12.6% (18 of 143). Of these 18 patients, 15 had low to medium titers of aCL Ab (10 with IgM, 4 with IgG, and 1 with both isotypes). β(2)GPI Ab and LA were detected in 3 (2.1%) and 2 (1.4%) patients with HBV infection, respectively. In follow-up specimens from 14 patients with elevated levels of aCL Ab or β(2)GPI Ab, 10 (71.4%) showed the persistent presence of aPLs. No clinical manifestations related to aPLs were identified.
Conclusion:
In HBV-infected patients, the most frequently detected antiphospholipid antibodies were IgM aCL Ab, which have a weak association with the clinical manifestations of APS. Unlike the transient presence reported for other infection-associated aPLs, most aPLs were persistently detected over a 12-week period in patients with HBV infection.
