Excess of a particular amino acid, or protein building block, in the blood may make neutrophils — a type of white blood cell that first responds to an infection or injury — more reactive in ANCA-associated vasculitis (AAV) and large-vessel vasculitis, a study has found. The amino acid, called…
The Johnson & Johnson COVID-19 vaccine may have triggered kidney inflammation associated with ANCA-associated vasculitis (AAV) in a 52-year-old woman, according to a recent case report. “We believe that this is the first case report of AAV that occurred following adenovirus vector COVID-19 vaccine administration,” its scientists wrote. “Increasing…
Measuring the blood levels of a protein called BAFF could help predict the chances of remission after induction treatment with rituximab in people with ANCA vasculitis (AAV), according to a new study. Determining the BAFF levels in the blood also could guide further care for AAV patients, the researchers…
Nonprofits, scientists, governmental organizations, and the rare disease drug development industry have long cited 7,000 as the average number of rare diseases in the world. But a new analysis shows there are as many as 10,867 rare diseases globally. And that…
Increased insulin resistance — measured by the triglyceride glucose (TyG) index — may predict which people diagnosed with ANCA-associated vasculitis (AAV) are at a greater risk of developing heart problems, a study found. Its predictive power may come from its association with metabolic disease at AAV diagnosis, data showed.
Levels of the immune signaling molecule interleukin-21 (IL-21) and the cells that produce the protein were elevated in the blood of people with ANCA-associated vasculitis (AAV) with myeloperoxidase (MPO) antibodies, a study found. IL-21 levels also were linked to higher MPO levels and disease activity, suggesting its direct involvement in…
Despite being in clinical remission based on physician evaluation, many people with ANCA-associated vasculitis (AAV) report experiencing ongoing disease symptoms, a study has found. Symptoms of pain and fatigue were the biggest indicators of active disease for patients in the study. These findings highlight the importance of considering…
Limited exposure to ultraviolet (UV) light and related drops in vitamin D levels — particularly over the winter months — may be linked to a greater risk of relapses among people with ANCA-associated vasculitis (AAV) in Ireland and the U.K., a data study found. But vitamin D status and…
People with granulomatosis with polyangiitis (GPA) may, in rare cases, develop dilated cardiomyopathy, a condition that causes the heart’s chambers to enlarge and become thinner, making it harder for it to pump blood effectively to the rest of the body, a recent case report shows. This case highlights the…
Undetectable blood levels of ANCAs within six months of remission induction treatment were associated with a lower risk of relapses over the next five years in people with ANCA-associated vasculitis (AAV), a study showed. The presence or absence of disease-causing antibodies did not seem to impact the risk of…
