ABSTRACT
Background: We report a 40-year- old female with co-existent lupus nephritis and thymoma who developed severe lupus flare (worsening nephritis, new onset hemolytic anemia) following SARS-CoV- 2 vaccine. Case: This 40 year old female has had stable lupus nephritis (LN) while maintained on mycophenolate mofetil and hydroxychloroquine for several years. A co-existent thymoma was likewise stable and did not require any added therapy apart from the management of the LN. She received the first dose of inactivated vaccine for SARS-CoV- 2 without event. Two weeks following the second dose, she developed Coombs positive hemolytic anemia (hemoglobin 64 g/L) with leukopenia (WBC 2.3 x 109/L), worsening nephritis (3+ proteinuria with uPCR 1.0, active urine sediments), hypocomplementemia, and elevated anti-dsDNA. She received methylprednisolone pulse therapy then maintained on prednisone 40mg/day with clinical improvement. Two weeks thereafter, she was admitted due to severe COVID-19 pneumonia accompanied by severe anemia requiring blood transfusion;she received a regimen of bevacizumab, dexamethasone, and remdesivir and was discharged recovered, without overt sequelae at the time of this report. Discussion(s): Vaccines are highly effective in reducing hospitalization and death attributable to SARS-CoV- 2 infection. There are concerns however regarding autoimmune disease flares following SARS-CoV- 2 vaccine, reported to occur in about 4% patients with autoimmune disorders. It is also possible that this patient's reaction may have been further aggravated by the co-existent thymoma. While there was apparent sub-optimal protection of the vaccine against moderate to severe COVID-19 infection in this patient, it may be conjectured that her significant recovery and response to the anti-viral combined with immunosuppressive regimen may be due to the high dose steroid treatment given for the post-vaccine autoimmune reaction.
ABSTRACT
Rheumatoid arthritis (RA) is a major health burden in Asia Pacific affecting the quality of life of patients and consuming healthcare resources. According to recent estimates from the World Health Organization-International League Against Rheumatism-Community Oriented Program for Control of Rheumatic Diseases, prevalence is around 0.3%-0.5%. Management guidelines have helped to improve treatment across this diverse region. To gain better insight into current real-world management applications in view of these guidelines, virtual meetings were conducted in mid-2020 to explore perspectives of rheumatologists and patients, as well as discuss the impact of coronavirus disease 2019 on RA management. Patients and rheumatologists from Hong Kong, Malaysia, Singapore, the Philippines, Thailand, India, Pakistan, and Taiwan were included, representing a diverse mix of healthcare systems, wealth, ethnicity and culture. Despite many countries having prospered in recent years, similar challenges in RA diagnosis and treatment were identified. The daily impact and patient experience of RA were also similar across countries, marked by "silent" pain and disability, and universal misunderstanding of the disease. Late diagnosis and treatment, and barriers to access to appropriate treatment, remain problematic. The experience shared by Taiwan offers a glimmer of hope, however, wherein patient advocacy groups have succeeded in being included in policy-making decisions and securing access to advanced treatment. Real-world solutions that pay heed to the unique local needs and diversity of Asia Pacific are required to improve RA management, which will take time. In the interim, help can be sought from the trained, non-rheumatologist community to reduce some of the disease burden.
