Since the publication of this paper, the authors have noticed an error.

On page 4 of the article, under the heading ‘Hematologic and immune parameters’, the last sentence should read:

‘Moreover, the patients’ median posttreatment serum IgA level of 32 mg/100 ml (±26, s.d.) was significantly less than the median pretreatment serum IgA level of 47 mg/100 ml (±44, s.d.; P<0.05, Student's t-test).’

The authors would like to apologize for any inconvenience caused.
