Fava et al. investigated longitudinal autoantibody profiles in patients with lupus nephritis (LN) to define serological biomarkers of histologic class. They found that baseline levels of anti-C1q and anti-double-stranded DNA antibodies may serve as noninvasive biomarkers of proliferative LN and anti-C1q antibodies may predict complete response.
“ANA’s are some of most commonly ordered tests but what exactly are they and what do you do with a positive ANA? Check out the Editor’s Pick for October to learn more,” says Physician Editor Bharat Kumar, MD, MME, FACP, FAAAAI, RhMSUS.
NEW ORLEANS—The COVID-19 pandemic brought to light the interplay of the SARS-CoV-2 virus and the immune systems of infected patients. Acute autoimmune manifestations of COVID-19, such as multisystem inflammatory syndrome in children (MIS-C) and myocarditis, clearly exist. A session at the 2023 Pediatric Rheumatology Symposium, Autoantibodies in COVID-19 explored this topic in detail, including a…
Patients with the rare DNASE1L3 biallelic null mutation present with childhood-onset disease that resembles lupus. This observation prompted research into how abnormalities in the enzyme DNASE1L3 are associated with lupus, with researchers finding autoantibody-mediated impairment of DNASE1L3 activity may be a common non-genetic mechanism leads to anti-dsDNA autoreactivity in SLE.
Researchers found nearly all systemic lupus erythematosus (SLE) patients have autoantibodies against long interspersed nuclear elements (LINE-1) p40. These findings suggest LINE-1 may be involved in the pathogenesis of SLE.
Research has found blood tests detect elevations of autoantibody isotypes in patients years before they are diagnosed with rheumatoid arthritis (RA). According to Kevin Deane, MD, PhD, identifying patients during this pre-RA period may be key to preventing or delaying the onset of RA.
A recent study details the autoantibodies of patients with myositis, confirming most patients carry these antibodies. The results also describe how myositis-specific autoantibodies can be used to identify distinct clinical subsets of idiopathic inflammatory myopathy…
In recent years, scientists and clinicians have learned a great deal about autoantibodies occurring in idiopathic inflammatory myopathies (IIMs). These new discoveries have reshaped our understanding of distinct clinical phenotypes in IIMs. Scientists continue to learn more about how these autoantibodies shape pathophysiology, diagnosis, disease monitoring, prognosis and optimum treatment. Moving forward, these autoantibodies will…
Researchers may have established a relationship between a new RA autoantibody, anti-carbamylated protein (anti-CarP) antibodies, and increased mortality risk. The recent study showed that anti-CarP was the only autoantibody associated with mortality, specifically respiratory system cause of death…
NEW YORK (Reuters Health)—An autoantibody to glial fibrillary acidic protein (GFAP) is associated with relapsing autoimmune meningoencephalomyelitis that is responsive to immunotherapy, researchers report. “Autoimmune GFAP meningoencephalomyelitis is the second autoimmune neurological disease in which the target of the immune attack is recognized to be the astrocyte type of brain cell,” Dr. Vanda A. Lennon…
