Intra-Alveolar Haemorrhage Complicating IgA Vasculitis: A Case Report, Literature Review and Discussion of Treatment.

INTRODUCTION

Immunoglobulin A vasculitis (IgAV) is a small-vessel vasculitis with IgA-dominant immune deposits. IgAV frequently involves the skin, gastrointestinal tract, joints and kidneys. In contrast to other types of small-vessel vasculitis, IgAV is rarely complicated by intra-alveolar haemorrhage (IAH).

METHODS/

RESULTS

We describe a patient with relapsing bladder cancer who presented with IAH during the course of IgAV successfully treated with corticosteroids alone.

CONCLUSION

This case report reminds us that IgAV can manifest with IAH. There are no robust data to support the systematic use of cyclophosphamide or plasma exchange as first-line therapy for IgAV with IAH.

LEARNING POINTS: Intra-alveolar haemorrhage in IgA vasculitis is an uncommon but important condition.The treatment strategies for IgA vasculitis and intra-alveolar haemorrhage and their rare association are discussed with reference to the literature.
