Anxiety as a possible predictor of acute GVHD

Abstract

In order to determine the influence of anxiety on the development of BMT complications and survival, we analysed data on 35 consecutive patients undergoing BMT in our Centre between June 1992 and December 1994. All patients received bone marrow from HLA-identical MLC non-responsive siblings. For GVHD prophylaxis, all patients received cyclosporin (CsA) and short methotrexate (MTX). The diagnosis and severity of acute GVHD were defined according to the Seattle Transplant Team criteria. The patients were tested with the Spielberger STAI test as a measure of anxiety as a state (STAI-S) and as a trait (STAI-T). The STAI-S/1 and STAI-T/1 were performed during the first week of isolation (day -5 to day -3 prior BMT) and STAI-S/2 and STAI-T/2 at the end of the discharge from laminar air flow units (day +35 to day +40 post-transplant). During isolation all patients had daily psychiatric support. Out of 35 patients, 31 (89%) fulfilled the STAI-S and STAI-T during the first week and at discharge from laminar air flow isolation. The level of anxiety at the beginning of isolation as measured by STAI-S/1 and STAI-T/1 tests had been significantly higher in patients who subsequently developed acute grade II-IV GVHD as compared to patients with GVHD grade 0-I (P < 0.001), irrespective of age, sex or stage of the disease prior to BMT. In those patients who died, the STAI-S/1, STAI-T/1 and STAI-T/2 tests had been almost identical to those of surviving patients, while STAI-S/2 had been significantly higher (P = 0.034). These data clearly indicate an association between the level of anxiety and the risk for BMT complications, but this should be confirmed in further controlled clinical trials.
