Prognostic value of cytokine levels in SERO TL+.

The prognostic value of cytokine levels measured at inclusion was evaluated by stepwise multivariate logistic regression analysis. For this, SERO TL+ individuals were spited into three categories according to follow-up results: those who were confirmed as HAT patients (SERO TL+/HAT; n = 12; G1), those who presented decreasing CATT responses (SERO TL+/CATTneg; n = 15; G2) and those who maintained high CATT responses and remained negative in parasitology (SERO TL+/CATT≥1/8; n = 13; G3). Three models were then constructed independently by a stepwise procedure comparing SERO TL+/HAT (model I), SERO TL+/CATTneg (model II) and SERO TL+/CATT≥1/8 (model III) to the two other groups.
