A 26-year-old female with B. cenocepecia presented with a history of recurrent small joint pains in association with intermittent painful erythematous nodular rash on the lower legs. This came on at the onset of an infective exacerbation of her chest. Biopsy confirmed erythema nodosum. Other causes of erythema nodosum were excluded, and she did not respond to Non-steroidal anti-inflammatory medications. Her symptoms continue to relapse in association with infective exacerbations of her chest.\nOf the remaining patients (n = 3), one presented with an erythematous rash on the lower legs and another had a purpuric rash on the lower legs and both were diagnosed clinically as leucocytoclastic vasculitis by a dermatologist. The third patient presented with purpuric areas and blistering of the lower legs which was confirmed as leucocytoclastic vasculitis on biopsy.\nOverall, two patients had biopsy proven leucocytoclastic vasculitis, three were clinically diagnosed with vasculitis but did not have biopsy confirmation and two had biopsies, which revealed other pathologies (erythema nodosum and capillaritis), giving an overall prevalence of cutaneous vasculitis in patients with Burkholderia cepacia complex of 16.7%. Out of the five patients with vasculitis, three had a raised ESR/CRP ratio.\nThere was no evidence of renal involvement in any patient – all had a negative urine dipstick and normal serum creatinine. The antinuclear antibody and antineutrophil cytoplasmic antibody were negative in all patients apart from one with biopsy proven leucocytoclastic vasculitis who had a transiently positive antineutrophil cytoplasmic antibody. Antistreptolysin O titre was tested in only two out of the five patients and was negative.\nMean forced expiratory volume1 was 30% (range: 18–55) of the predicted value. In four patients (57%), the forced expiratory volume1 was lower at the time of presentation with rash compared to the baseline forced expiratory volume1 values for the previous two years.\nAll patients received antibiotics for a presumed pulmonary exacerbation at onset of the rash. Three patients received specific treatment for vasculitis (prednisolone ± additional immunosuppressive) after non-resolution of the rash.
A 32-year-old male with a history of B. cenocepacia and Burkholderia multivorans developed an erythematous rash on the lower legs associated with an infective exacerbation of his chest. The rash resolved leaving grey discolouration but would occasionally flare up in the summer months. The biopsy showed features of capillaritis, and he was managed with topical steroids and compression hosiery.
