Expression of concern: Ahlin E et al.,"Anti-citrullinated peptide antibodies and rheumatoid factor in Sudanese patients with Leishmania donovani infection", Rev Bras Reumatol 2011; 51(6):572-86
In December 2011, the Brazilian Journal of Rheumatology (BJR) published the article "Anti-citrullinated peptide antibodies and rheumatoid factor in Sudanese patients with Leishmania donovani infection" by Ahlin E, Elshafei A, Nur M, El Safi SH, Johan R, and Elghazali G. [Rev Bras Reumatol 2011; 51(6):572-86]. On January 2012, the BJR received a claim from one of the authors questioning the authorship of the corresponding author and informing that the article was under submission to another journal, by Ahlin E, Elshafie AI, Nur MAM, and Rönnelid J. This submission is on hold, and the authors were all informed of the claim. The case was submitted to the Committee on Publication Ethics (COPE), which suggested some recommendations. The investigation has not yet reached a conclusion. Pending the results of the investigations, BJR is publishing this Expression of concern editorial to alert our readers to the fact that serious questions have been raised about the authorship in the Ahlin E et al. paper.
