A 62-year-old man was admitted to our hospital because of low-grade fever and hemoptysis. Chest roentgenogram revealed diffuse infiltrative shadows with air bronchograms. Bronchoalveolar lavage fluid demonstrated bloody fluid, including many hemosiderin-laden macrophages. In addition, his laboratory data on admission revealed elevation of serum creatinine and BUN, and proteinuria and hematuria on urinalysis. Renal needle biopsy showed atrophic glomeruli and mesangial proliferative glomerulonephritis without crescent formation. A history of wheezing and slight eosinophila was also present, and we therefore suspected allergic granulomatous angitis. We performed airway sensitivity and reversibility tests, which were positive, and so we judged that he had an asthmatic component. Perinuclear antineutrophil cytoplasmic antibody (P-ANCA) was positive (x 1000) with ELISA. We diagnosed diffuse alveolar hemorrhage with mesangial proliferative glomerulonephritis and bronchial asthma. His general condition improved with oral administration of corticosteroid (50 mg/day) and immunosuppressive agent (cyclophosphamide; 50 mg/day), and his major symptoms disappeared within a few days.

Hypersensitivity to inulin (polyfructan) is a rare event; two cases of food allergy and some patients presenting with allergy and hypersensitivity after inulin infusion have been reported. An 11-year-old boy suffering from severe immunoglobulin (Ig)A nephropathy (IgAN) experienced both anaphylactic reaction and concomitant relapse of his nephropathy following inulin infusion, used for measuring glomerular filtration rate (GFR) 2 years after the appearance of his initial symptoms. Pruritus, wheezing and cough were observed during a first renal function test; results of prick and intradermal tests were negative for inulin. The patient presented with pallor, asthenia and oliguria when a second inulin infusion was performed under dexchlorpheniramine, leading to the immediate cessation of the infusion. He was readmitted 2 days later because of fatigue and nausea related to acute renal failure. A drug-induced acute interstitial nephritis was first suspected. However, due to the presence of macroscopic haematuria and proteinuria, a renal biopsy was performed and showed acute proliferative relapse of IgAN. The underlying mechanism of inulin hypersensitivity is not well known. We can hypothesize that inulin had activated the innate immune system. Inulin may, thus, have been the initiating event of the renal relapse, acting like an infection, in a patient with IgA-mediated immunological dysregulation.
