RESUMO

Autoinflammatory diseases (AIDs) are a relatively new family disorders defined approximately 20 years ago. AIDs are caused by defect(s) or dysregulation of the innate immune system, characterized by recurrent or continuous inflammation and lack of a primary pathogenic role for the adaptive immune system. One AID, NLRP3-associated autoinflammatory disease (NLRP3-AID), involves a clinical presentation since the neonatal period or childhood, with multiple inflammatory recurrent symptoms that appear throughout the patient´s life. We present the first case of NLRP3-AID in Ecuador. The patient presented recurrent fever since 6 months of age associated with urticarial rash, arthralgias, and abdominal pain; recently, he had a seizure at 7 years of age. Brain MRI revealed demyelinating lesions, and genetic testing uncovered a de novo mutation in the NLRP3 gene. The patient had a good clinical response to treatment with canakinumab.

RESUMO

Resumen La granulomatosis con poliangeítis (GPA) es una vasculitis de pequeno y mediano calibre caracterizada por la formación de granulomas e inflamación necrosante con predilección de las vías respiratorias y los glomérulos. Se reporta el caso de una adolescente de 14 an os que comienza con hipoacusia y lesiones cutáneas; sinusitis, epiescleritis, PR3-ANCA positivo y biopsia de piel con infiltrado neutrofílico y necrosis. La GPA puede presentar manifestaciones otológicas y dermatológicas como signo inicial, es importante tomarlo en consideración en el diagnóstico diferencial.


Abstract Granulomatosis with polyangiitis is a small- and medium-sized vasculitis. It is characterised by formation of granulomas and necrotising inflammation with a predilection for the respiratory tract and glomeruli. The case is presented of a 14-year-old female debuting with hypoacusis, skin lesions, sinusitis; episcleritis, anti-PR3 ANCA positivity and histological findings from the skin lesions with neutrophilic infiltration, necrosis and fibrin. Granulomatosis with polyangiitis can present otological and skin manifestations as initial signs, and it is important to take the differential diagnosis into consideration.

RESUMO

Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril. One year later, he was admitted to Dr Roberto Gilbert Children's Hospital because of intracranial hemorrhage. Angiography revealed enlargement of aneurysms enlargement and new aneurysms. He also developed portal hypertension. Treatment with intravenous corticosteroids, azathioprine, and monthly intravenous cyclophosphamide was begun. After 6 months of no improvement, infliximab was begun. The aim of this article was to report the concurrence of coronary involvement and portal vein hypertension in pediatric TA because there were scarce reports on this matter.
