Abstract
Growing evidence reveals the important role of clinical psychological factors in chronic-immune diseases. The aim of this study was to investigate Health-Related Quality of Life (HR-QoL), depression, anxiety, and alexithymia in patients with severe hypersensitivity reactions such as Severe Allergic Asthma (SAA) and Hymenoptera Venom Anaphylaxis (HVA). The Short-Form Health Survey-36 (SF-36), the Beck Depression Inventory Questionnaire (BDI-II), the Hamilton Anxiety Rating Scale (HAM-A) and the Toronto Alexithymia Scale (TAS-20) were used to assess HR-QoL and clinical psychological features of patients with SAA and HVA. Overall, 78 patients were recruited. Patients with SAA (n = 35) reported lower scores for physical functioning [65 (58-75) vs. 90 (85-95); p = <0.001], role limitations due to physical health [25 (0-50) vs. 62 (50-75); p = 0.004], bodily pain [47.5 (41.1-61.3) vs. 55.5 (55-96); p = 0.001], general health [40 (30-60) vs. 70 (50-80); p = 0.0003] and social functioning [50 (37.5-62.5) vs. 62.5 (54.9-75); p = 0.007] while higher scores for depressive symptoms [14 (11-15.4) vs. (9.5 (6-15.4); p = 0.05)] compared to HVA patients (n = 43). All the dimensions of SF-36 were negatively correlated with anxiety (r from -0.26 to -0.66; p all < 0.01) and depressive symptoms (r from -0.44 to -0.73; p all < 0.001). Alexithymia was negatively correlated with vitality (r = -0.28; p = 0.02) and mental health (r = -027; p = 0.03). Additionally, patients with alexithymia (38% of participants) showed higher levels of depressive symptoms [9.5 (10-19) vs. 14 (6-13.9); p = 0.005] and anxiety levels [31 (27.9-35) vs. 24 (16-33.9); p = 0.02]; they also showed less vitality [40 (39.9-50) vs. 55 (50-60) p = 0.01], social functioning [50 (37.5-62.5) vs. 62.5 (50 vs. 75); p = 0.01] and mental health [48 (44-60) vs. 68 (56-76); p = 0.004]. Clinical psychological features due to severe hypersensitive reactions may contribute to the patient's perceived HR-QoL. Focused clinical psychological interventions should be promoted to improve the clinical management of such conditions.
