Editorial expression of concern

In the December 2011 issue, the Brazilian Journal of Rheumatology published the article: "Anticitrullinated peptide antibodies and rheumatoid factor in Sudanese patients with Leishmania donovani infection" by E. Ahlin, A. Elshafei, M. Nur, S.H. El Safi, R. Johan, and G. Elghazali. [Revista Brasileira de Reumatologia 51, 6 (2011)]. On January 2012, the BJR received a claim from one of the authors, questioning the authorship of the corresponding author, and informed that the article was under submission to another journal, by E. Ahlin, A.I. Elshafie, M.A.M. Nur, and J. Ronnelid. This submission is on hold, the authors were all informed of the claim and the case was submitted to the Committee on Publication Ethics (COPE), which gave some recommendations. The investigation has not yet reached a conclusion. Pending the results of the investigations, BJR is publishing this Editorial Expression of Concern to alert our readers to the fact that serious questions have been raised about the authorship in the Ahlin et al. paper.
