Matthew Jimenez v. HHS - HPV, systemic juvenile idiopathic arthritis (sJIA) (2021)

On September 5, 2017, Matthew Jimenez, a minor, filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging that he suffered from systemic juvenile idiopathic arthritis (sJIA) as a result of Hepatitis A (Hep A) and human papillomavirus (HPV) vaccinations he received on September 18, 2014. Petitioner's counsel was Richard Gage.

Respondent was the Secretary of Health & Human Services, represented by Traci R. Patton.

Special Master Nora Beth Dorsey presided over the case. The petitioner argued that the HPV vaccine, and possibly the Hep A vaccine, caused his sJIA by triggering an aberrant immune response in his genetically susceptible system.

His expert, Dr. M.

Eric Gershwin, proposed a theory involving cytokine dysregulation and macrophage activation, supported by medical literature and the petitioner's clinical presentation, including elevated inflammatory markers and improvement with cytokine inhibitors. Respondent's experts, Dr.

Carlos D. Rosé and Dr.

Craig D. Platt, contested the diagnosis, suggesting a variant of Cryopyrin-Associated Periodic Syndrome (CAPS), specifically Muckle-Wells Syndrome (MWS), or arguing that sJIA is not vaccine-related and that the temporal association was not proximate.

The petitioner's medical history included a rash approximately one week after vaccination, followed by fevers, night sweats, joint pain, and body aches. Extensive medical evaluations led to a diagnosis of sJIA.

The court found that the petitioner had established by a preponderance of the evidence that he suffers from sJIA and that the HPV vaccine caused his condition, satisfying the three prongs of the Althen test for causation. Entitlement to compensation was granted, with damages to be determined in a separate order.

The public decision does not describe the specific details of the damages award or annuity terms.
