Performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care.

OBJECTIVE: To assess the performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care. METHODS: Participants in both phases completed the J-PHQ-9, while patients in the second phase also completed the SF-8 (the short form for the health-related QOL scale SF-36). Subjects (n = 284; male = 107, female = 177) had to return the questionnaires to their health care professional within 48 hours and undergo a diagnostic evaluation interview based on the Japanese version of M.I.N.I-Plus. RESULTS: 93 patients were diagnosed as having major depressive disorder (MDD). In the J-PHQ-9, the optimal cutpoint ≥ 10 had sensitivity of 90.5% and specificity of 76.6%. As for the categorical algorithms, the sensitivity was 80.6%; specificity was 89.5%, and a positive likelihood ratio of 7.7. The Stratum-specific likelihood ratios (SSLRs) of the J-PHQ-9 scores of 0-9, 10-14, 15-19, and 20-27 for major depression were 0.10 (95% CI: 0.05-0.20), 1.67 (95% CI: 1.02-2.76), 5.41 (95% CI: 2.87-10.22), and 11.98 (95% CI: 5.39-26.63), respectively. The relationship between the severity of J-PHQ-9 and the MCS of SF-8 was significant (χ 2 ＝ 85.72, df = 4, P ≤ 0.0001). CONCLUSIONS: This study has validated the J-PHQ-9 as a useful tool for the assessment of MDD in primary care in Japan.

Comparative Study of Infliximab Therapy and Methotrexate Monotherapy to Improve the Clinical Effect in Rheumatoid Arthritis Patients.

Objective We examined whether infliximab (IFX) therapy was more effective than methotrexate (MTX) monotherapy to achieve an improvement in depressive states in Rheumatoid Arthritis (RA) patients. Methods We examined 152 RA patients (72 IFX patients and 80 MTX patients). We conducted an open-label cohort study to evaluate the disease activity of RA (Simplified Disease Activity Index; SDAI), depressive states (Hamilton Rating Scale for Depression; HAM-D), Activity of Daily Living (ADL) (modified Health Assessment Questionnaire; mHAQ) and Quality of Life (QOL) [Short Form (SF)-36] in patients before and 6 months after receiving therapy. The HAM-D, SDAI, mHAQ and SF-36 scores after 6 months of therapy were measured as the outcomes. Results We analyzed 60 IFX patients and 53 MTX patients. The HAM-D scores significantly improved in both groups (p<0.001), but there was no significant difference in the effectiveness between the IFX and MTX therapies (p=0.792). The SDAI scores significantly improved in both groups after therapy (p<0.001), and IFX therapy was more effective than MTX therapy (p=0.004). The mHAQ and HAM-D scores also improved significantly in both groups after therapy (p<0.001), but no significant difference in the effectiveness between the IFX and MTX therapies was observed (p=0.272, 0.792). The scores of all 8 items of the SF-36 improved in both groups after therapy, but IFX therapy was more effective than MTX therapy in only 4 of the 8 items (p<0.05). Conclusion Both IFX and MTX therapy improved the clinical efficacy, ADL, QOL and depressive states. However, no significant differences regarding an improvement in the depressive states and ADL were observed between IFX therapy and MTX monotherapy.

Combined infliximab and methotrexate treatment improves the depressive state in rheumatoid arthritis patients more effectively than methotrexate alone.

OBJECTIVE: Rheumatoid arthritis (RA) patients have a greater depressive tendency than normal subjects, and infliximab is known to provide quick therapeutic effects and to have high bioavailability for RA. We therefore investigated whether the depressive state of RA patients would be improved by infliximab. MATERIAL AND METHODS: The Self-Rating Depression Scale (SDS) was used to evaluate 34 RA patients before and 14 or 30 weeks after inflixi mab treatment using the SDS and Disease Activity Score (DAS) 28. The SDS and DAS28 results before and after treatment were compared. RESULTS: We also included 42 cases treated with methotrexate as the control group. The SDS decreased in both groups, and the intraindividual vari ability was p<0.001, indicating that the drugs had significantly different effects on the SDS. The DAS tended to decrease in both groups, but the intraindividual variability was p=0.199, indicating no difference between the two drugs. CONCLUSION: This study is a preliminary study, but the data suggest that infliximab may reduce RA disease activity and improve the depressive state.

Depression is improved when low-dose tacrolimus is given to rheumatoid arthritis patients showing an inadequate response to biologic agents.

PURPOSE: Depression in rheumatoid arthritis (RA) patients is more severe than in healthy people. Herein, we report improved depression in RA patients using biologic agents. We examined whether depression was improved by tacrolimus combination therapy when biologic agents were ineffective. METHOD: The study included 13 RA patients who used biologic agents. The following methods were used before the initiation of tacrolimus combination therapy and at 14 and 30 weeks after treatment initiation: the Zung self-rating depression scale (SDS) to evaluate depression state, disease activity score 28/erythrocyte sedimentation rate (DAS28), tender joint counts, swollen joint counts, a patient global assessment to evaluate RA disease activity, and the modified health assessment questionnaire (mHAQ) to evaluate quality of life. RESULTS: The SDS scores before the initiation of tacrolimus combination therapy and at 14 and 30 weeks after treatment initiation were 45.2 ± 10.6, 44.8 ± 12.8, and 41.6 ± 11.2 (p = 0.047), respectively, indicating significant improvement. The DAS28 was 5.0 ± 1.3 prior to treatment, 3.8 ± 1.3 at 14 weeks, and 3.5 ± 0.9 at 30 weeks, demonstrating significant improvement at both 14 and 30 weeks (p < 0.001). The mHAQ score changed from 0.60 ± 0.45 at baseline to 0.54 ± 0.52 and 0.38 ± 0.43 at 14 and 30 weeks, respectively. The mHAQ score was significantly lower at 30 weeks when compared to baseline (p = 0.013). CONCLUSION: Tacrolimus combination therapy does not directly improve depression in RA patients, but it is possible that the observed improvement in depression accompanies the improvement in the secondary failure of RA.

Three-year clinical outcome in type 2 diabetic patients with drug-eluting stents versus bare-metal stents with pioglitazone.

AIMS: The aim of this study was to examine outcome subsequent to implantation of bare-metal stents (BMS) with pioglitazone, which are novel insulin-sensitizing agents, and drug-eluting stents (DES) in patients with diabetes. METHODS AND RESULTS: A total of 139 consecutive Type 2 diabetic patients treated with stent were followed up for 3 years. Data on death, myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis were ascertained from January 2003 to January 2006. Eighty-nine patients were treated with a BMS with pioglitazone, and 50 patients were treated with a DES. The incidence of MI was 1.1% in the BMS with pioglitazone group, 4.0% in the DES group [relative risk RR):0.52; 95% CI: 0.10-2.56]. The incidence of TLR was 22.5% in the BMS with pioglitazone group, 28.0% in the DES group (RR 0.89; 95% CI: 0.65-1.22). The incidence of stent thrombosis was 1.0% in the BMS with pioglitazone group, 4.0% in the DES group (RR 0.52; 95% CI: 0.10-2.56). Overall 3-year mortality was similar in the two groups (RR 0.77; 95% CI: 0.34-1.74). CONCLUSIONS: During 3 years of follow-up, patients treated with BMS with pioglitazone had similar risks of death, TLR, MI, and stent thrombosis compared with patients treated with DES.
