Mycobacterium tuberculosis monoarthritis in a child

A child with isolated Mycobacterium tuberculosis monoarthritis, with features initially suggesting oligoarthritis subtype of juvenile idiopathic arthritis, is presented. This patient illustrates the need to consider the possibility of tuberculosis as the cause of oligoarthritis in high-risk pediatric populations even in the absence of a tuberculosis contact history and without evidence of overt pulmonary disease

Elevated serum interleukin 1 receptors and interleukin 1B in patients with Behçet's disease: correlations with disease activity and severity

Soluble interleukin 2 receptor (SIL-2R) and interleukin 1-B (IL-1B) levels in peripheral blood were assayed by enzyme-linked immunoabsorbent method in 25 patients with Behçet's disease and in 20 healthy controls. Eighteen patients suffered from active Behçet's disease and 6 patients had severe disease manifestations. SIL-2R levels were followed for a period of 16 months and were correlated with disease activity. In all the patients with Behçet's disease the levels of SIL-2R and IL-1B were significantly higher than their control, 958 +/- 712 vs. 404 +/- 119 u/ml (P < 0.001) for SIL-2R and 639 +/- 741 vs. 59 +/- 53 pg/ml (P < 0.001) for IL-1B. No correlation was found between disease activity and severity and the levels of SIL-2R and IL-1B. It is suggested that levels of SIL-2R and IL-1B are elevated in patients with Behçet's disease but do not serve as disease activity markers
