Assessment of health-related quality of life in individuals with depressive symptoms: validity and responsiveness of the EQ-5D-3L and the SF-6D

Background The EQ-5D and the SF-6D are examples of commonly used generic preference-based instruments for assessing health-related quality of life (HRQoL). However, their suitability for mental disorders has been repeatedly questioned. Objective To assess the responsiveness and convergent validity of the EQ-5D-3L and SF-6D in patients with depressive symptoms. Methods The data analyzed were from cardiac patients with depressive symptoms and were collected as part of the SPIRR-CAD (Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease) trial. The EQ-5D-3L and SF-6D were compared with the HADS (Hospital Anxiety and Depression Scale) and PHQ-9 (Patient Health Questionnaire) as disease-specific instruments. Convergent validity was assessed using Spearman's rank correlation. Effect sizes were calculated and ROC analysis was performed to determine responsiveness. Results Data from 566 patients were analysed. The SF-6D correlated considerably better with the disease-specific instruments (|r(s)|= 0.63-0.68) than the EQ-5D-3L (|r(s)|= 0.51-0.56). The internal responsiveness of the SF-6D was in the upper range of a small effect (ES: - 0.44 and - 0.47), while no effect could be determined for the EQ-5D-3L. Neither the SF-6D nor the EQ-5D-3L showed acceptable external responsiveness for classifying patients' depressive symptoms as improved or not improved. The ability to detect patients whose condition has deteriorated was only acceptable for the EQ-5D-3L. Conclusion Overall, both the convergent validity and responsiveness of the SF-6D are better than those of the EQ-5D-3L in patients with depressive symptoms. The SF-6D appears, therefore, more recommendable for use in studies to evaluate interventions for this population

Chronic myeloid leukemia patients who develop grade I/II pleural effusion under second-line dasatinib have better responses and outcomes than patients without pleural effusion

Dasatinib is a potent second generation TKI, and it is widely used in patients with CML, both in the up-front setting and failure after imatinib. Lymphocytosis in cases receiving dasatinib therapy has been shown to be associated with pleural effusion (PE) and better outcome. Although patients who gather lymphocytosis during dasatinib have superior responses, there is only little data about the correlation between PE, response rates, and survival. In order to answer this question, the aim of our study was to determine the frequency of PE and lymphocytosis among our CML patients receiving second-line dasatinib, and to compare the responses and outcomes between patients with or without PE. There were 18 patients (44%) who developed PE, in a total of 41 patients, with a median time of 15 months. Lymphocytosis was observed in nine patients (9/41, 22%) with a median duration of 6.5 months of dasatinib treatment. There were fourteen patients with at least one comorbidity that may play a role in the generation of PE. The cumulative MMR and CCyR rates were greater in PE+ patients (p < 0.05). The PFS was significantly higher in PE+ group than PE-patients (p = 0.013), also the OS was higher among PE+ patients than PE- group (p = 0.042). In patients with a grade I/II PE, and durable responses under dasatinib, performing the management strategies for the recovery of effusion, together with continuing dasatinib can be a reasonable choice mainly in countries where third generation TKIs are not available. But alternative treatment strategies such as nilotinib or third generation TKIs can be chosen in patients with grade III/IV PE especially if the quality of life is severely affected.

Longitudinal relationship between B-type natriuretic peptide and anxiety in coronary heart disease patients with depression

Objective: Patients with coronary heart disease (CHD) suffer from physical limitations, but also from psychological distress. Natriuretic peptides may be involved in the neurobiological processes that modulate psychological adaptation, as they are increased in heart disease and seem to have an anxiolytic-like function. Longitudinal data on this association are scarce. Methods: To assess the relationship between NT-proBNP and anxiety (Hospital Anxiety and Depression Scale (HADS)), we used secondary data from a multicenter trial from baseline to 24 months. Patients (N = 308, 80.8% male, mean age 60.1 years) had stable CHD and moderate levels of depression (HADS >= 8). Results: Multiple linear regression adjusted for age, sex, BMI, and physical functioning revealed NT-proBNP as a significant predictor for anxiety at baseline, 1, 6, 12, 18, and 24 months (all p < .05). Linear mixed model analysis with the six anxiety measures as level-1 variable and NT-proBNP as fixed factor revealed a significant time*NT-proBNP interaction (t(1535.99) = -2.669, p = .01) as well as a significant time*NT-proBNP*sex-interaction (1(1535.99) = 3.277, p = .001), when NT-proBNP was dichotomized into lowest vs. the three highest quartiles. Conclusion: Our results indicate a stable negative association of baseline NT-proBNP with anxiety over two years. In men and women, different pathways modulating this relationship appear to be in effect. Female patients with very low NT-proBNP levels, despite their cardiac disease, show persistently higher levels of anxiety compared to women with higher levels of NT-proBNP and compared to men
