BACKGROUND In ANCA-associated vasculitis the acute phase of the disease is often preceded by prodromal symptoms. The aim of the present study was to analyze the relation between the duration of the prodromal phase and renal damage. METHODS Patients with ANCA-associated vasculitis and renal involvement from a retrospective single-center cohort were divided into two equal groups based on the du...

Kawasaki disease (KD) is an inflammatory vasculitis. KD is classified into two groups based on clinical characteristics criteria, namely classic and incomplete. Cerebral vascular abnormality, especially arterial ischemic stroke (AIS) is very rare and unusual in KD. Here, we report a 4-year-old boy who was referred to our tertiary pediatric center with abrupt right hemiparesis and aphasia. At ad...

Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common.

The clinical and pathological findings in a fatal case of farmer's lung in a 17-year-old youth are described. His lungs were uncomplicated by chronic disease, and his first exposure to mouldy hay probably occurred only weeks before his death. As this was an acute attack, whose duration could be measured in days, the changes seen are probably the earliest to be recorded, and the probable nature ...

An acute confusional state, which developed in a patient with polyarteritis nodosa (PAN), proved to be secondary to inappropriate secretion of antidiuretic hormone and consequent hyponatraemia. This is a very unusual complication of PAN and may well reflect a direct stimulation of the supraoptic nuclei owing to cerebral vasculitis.

Q fever is a zoonosis caused by the rickettsial organism Coxiella burnetii. Infection has an acute course, usually with a self-limited febrile illness and the possibility of the evaluation to a chronic course with endocardial involvement. The presence of autoantibodies and various autoimmune disorders have also been associated with C. burnetii infection. We report a case of acute Q fever in whi...

COVID-19 is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and has been shown to affect a multitude of organ systems. It often associated with vasculitis or thromboembolic disease resultant tissue hypoxia. This report presents case fast progression diabetic retinopathy in the SARS-CoV-2 infection. The findings conclude that patients diabetes should be more frequently mon...

Granulomatosis with polyangiitis (GPA), known as Wegener’s granulomatosis, is characterized by systemic necrotizing vasculitis in small and medium sized vessels affecting the upper and lower respiratory tracts, paranasal sinuses, and kidneys (1).
