In the present issue of NDT, Chan et al. [1] report that the messenger (m) RNA expression of T-bet (a central Th1 transcription factor), interleukin (IL)-10, transforming growth factor (TGF)-ß and MCP-1 in the urinary sediment of patients with active lupus nephritis decrease with successful immunosuppressive therapy. Importantly, various other cytokine mRNAs, including those of IL-2, -4, -12 and -18 did not change during the 6 month follow-up period. These observations extend to a number of prior studies by the same group [2,3] and add to a growing list of molecules (pro-inflammatory cytokines, fibrosis markers, etc.) that have been assessed in the urinary sediment of patients with various renal diseases (Table 1).
