IgAV is primarily a childhood disease, occurring between the ages of 3 and 15 years [3,4]. In a population-based study in the United Kingdom, the annual incidence was approximately 20 per 100,000 in children under 17 years of age and 70 per 100,000 in children under four years of age. In a population-based study in France, the annual incidence was 19 per 100,000 children. In a South Korean study, the incidence was approximately 56 cases per 100,000 children in one study.

IgAV is less common in adults, with an annual incidence of 5 cases per 100,000 adults in Slovenia. In several retrospective studies, 20–30% of patients with IgAV were elderly patients. Most studies report a male-to-female ratio of 1.2:1 to 1.8:1, indicating that IgAV is more common in men [9, 18].

A 67-year-old male patient was admitted to the emergency department of our hospital in April with the following complaints: Fatigue, weakness, dizziness, pain in the shoulder, especially the right arm, which increases with arm movement, pain in the epigastric region, and weight loss. According to him, he has had these complaints since September, but in recent days the complaints have increased, and he has lost 14 kg of weight from September to April, which is why he was admitted to the hospital. He has a history of type 2 diabetes, takes Lantus and metformin, and has hypertension. According to him, he had surgery for papilloma in his bladder in 2019, and the biopsy showed it to be benign. He notes that his creatinine was normal that year. He was first diagnosed with high creatinine (3.2 mg/dl) in an analysis he gave at another hospital at the end of March.
