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…
ANCA-associated vasculitis (AAV) emerged as a side effect of levamisole given for years to treat a 15-year-old boy with idiopathic nephrotic syndrome, according to a case report. “By reporting this case, we want to raise awareness among clinicians regarding a rare complication of treatment with Levamisole that is often…
A 65-year-old man developed granulomatosis with polyangiitis (GPA), a type of anti-neutrophilic cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV), after receiving a stem cell transplant for another autoimmune condition, according to a case report. “[Our] case report suggests that [AAV] may develop in the setting of stem cell transplantation and must…
People with eosinophilic granulomatosis with polyangiitis (EGPA) are more likely to report a greater range of symptoms than their doctors, a study that drew on patient- and physician-reported databases found, while showing similarities on other points, like relapse frequency. Given the importance of the patient perspective in both research and…
