RESUMO
OBJECTIVE: To validate standard self-report questionnaires for depression screening in patients with rheumatoid arthritis (RA) and compare these measures to one another and to the Montgomery-Åsberg Depression Rating Scale (MADRS), a standardized structured interview. METHODS: In 9 clinical centers across Germany, depressive symptomatology was assessed in 262 adult RA patients at baseline (T0) and at 12 ± 2 weeks followup (T1) using the World Health Organization 5-Item Well-Being Index (WHO-5), the Patient Health Questionnaire (PHQ-9), and the Beck Depression Inventory II (BDI-II). The construct validity of these depression questionnaires (using convergent and discriminant validity) was evaluated using Spearman's correlations at both time points. The test-retest reliability of the questionnaires was evaluated in RA patients who had not undergone a psychotherapeutic intervention or received antidepressants between T0 and T1. The sensitivity and the specificity of the questionnaires were calculated using the results of the MADRS, a structured interview, as the gold standard. RESULTS: According to Spearman's correlation coefficients, all questionnaires met convergent validity criteria (ρ > |0.50|), with the BDI-II performing best, while correlations with age and disease activity for all questionnaires met the criteria for discriminant validity (ρ < |0.50|). The only questionnaire to meet the predefined retest reliability criterion (ρ ≥ 0.70) was the BDI-II (rs = 0.77), which also achieved the best results for both sensitivity and specificity (>80%) when using the MADRS as the gold standard. CONCLUSION: The BDI-II best met the predefined criteria, and the PHQ-9 met most of the validity criteria, with lower sensitivity and specificity.

Tocilizumab (TCZ) and tumour necrosis factor inhibitors (TNFi) are recommended for the treatment of rheumatoid arthritis (RA) in patients with inadequate response (IR) to prior disease-modifying antirheumatic drugs (DMARDs). This retrospective analysis assessed the efficacy of TCZ and TNFi, alone or in combination with DMARDs, in 1603 patients with IR to previous treatment with either DMARDs (DMARD-IR) and/or TNFi (TNFi-IR), initiating treatment with TCZ or a TNFi, managed in routine clinical practice. Patients were grouped according to treatment history and treatment initiated: DMARD-IR patients initiating treatment with TCZ + DMARD (DMARD-IR TCZ) or TNFi + DMARD (DMARD-IR TNFi), DMARD-IR and/or TNFi-IR patients initiating treatment with TCZ monotherapy (TCZ mono) or TNFi monotherapy (TNFi mono), and TNFi-IR patients initiating treatment with TCZ + DMARD (TNFi-IR TCZ) or TNFi + DMARD (TNFi-IR TNFi). Patients initiating treatment with TCZ generally had more severe disease and longer disease duration compared with the corresponding TNFi group. Significantly more patients achieved remission (DAS28 ESR <2.6) in the TCZ groups compared with corresponding TNFi groups (DMARD-IR, TCZ 44.0 % vs. TNFi 29.6 %; monotherapy, TCZ 37.2 % vs. TNFi 30.2 %; TNF-IR, TCZ 41.3 % vs. TNFi 19.2 %; p < 0.001 for all comparisons). More patients achieved moderate-good responses (EULAR criteria) in the TCZ treatment groups (79-85 %) compared with TNFi treatment groups (65-81 %). Patient-reported outcomes showed greater improvements in TCZ compared with TNFi groups. In patients with inadequate response to DMARDs and/or TNFi treated in routine clinical practice, TCZ in combination with DMARDs or as monotherapy resulted in significantly more patients achieving remission and more marked improvements in patient-reported outcomes compared with TNF inhibitors.

This study aims to investigate the use of biological disease-modifying antirheumatic drugs (bDMARDs) as monotherapy in patients with rheumatoid arthritis (RA) in "real world" clinical settings and to compare tumor necrosis factor (TNF) inhibitors and tocilizumab monotherapy in terms of efficacy and patient and clinician satisfaction with treatment. This study made use of a retrospective, cohort-19 based study including included data from 254 patients (TNF inhibitors n = 128; tocilizumab n = 126) managed in 30 centers throughout Germany. Efficacy of monotherapy and patient and physician overall satisfaction with treatment were assessed at baseline, 3, and 6 months of monotherapy using a range of measures including Disease Activity Score 28 joint (DAS28), swollen joint count (SJC) and tender joint count (TJC), and visual analogue scales (VAS). Between 18 and 41 % of patients treated with bDMARDs received the agent as monotherapy. Intolerance to DMARDs, contraindications for combination therapy, and comorbidities were the most common reasons for introduction of bDMARD monotherapy. Mean DAS28 (erythrocyte sedimentation rate, ESR) was significantly lower at 3 and 6 months following tocilizumab vs. TNF inhibitors (p ≤ 0.001). Joint counts improved from baseline to month 6 in both groups (SJC -5.1 vs. -3.7 and TJC -5.6 vs. -5.1, for tocilizumab and TNF inhibitors, respectively). Patient as well as physician satisfaction (VAS 100 mm scale) was significantly higher for tocilizumab vs. TNF inhibitors (75.3 vs. 66.8; p = 0.001 and 74.9 vs. 67.1, p = 0.003, respectively). Significantly more patients remained on tocilizumab monotherapy vs. TNF-inhibitor monotherapy (89.7 vs. 75.8 %; p < 0.01). Monotherapy with bDMARDs is common in routine clinical practice. Tocilizumab monotherapy appeared to be superior over TNF-inhibitor monotherapy with respect to DAS28 and drug adherence.

OBJECTIVE: Obesity in transplant recipients is a frequent phenomenon but data from body composition analyses in long-term survivors are limited. Body composition and energy metabolism were studied in patients after liver (LTX) and kidney (KTX) transplantation and patients with liver cirrhosis (LCI) or on chronic hemodialysis (HD) and compared to healthy controls. METHODS: In 42 patients 50.0 mo (median; range 17.1-100.6) after LTX and 30 patients 93.0 mo (31.2-180.1) after KTX as wells as in LCI (n = 39) or HD (n = 10) patients mid-arm muscle and fat area, body cell mass, and phase angle (bioimpedance analysis), and resting energy expenditure (indirect calorimetry, REE(CALO)) were measured. RESULTS: Obesity was more prevalent in LTX (17%) than LCI (3%) and in KTX (27%) than in HD (10%). In LTX and KTX, phase angle was higher than in end-stage disease (LTX 5.6° [4.1-7.2] versus LCI 4.4° [2.9-7.3], P < 0.001; KTX 5.9° [4.4-8.7] versus HD 4.3° [2.9-6.8]) but was lower in all patient groups than in controls (7.1°; 4.6-8.9; P < 0.001). In LCI and HD REE(CALO) was higher than predicted, while in LTX and KTX REE(CALO) was not different from predicted REE. CONCLUSIONS: Despite excellent graft function, many long-term LTX or KTX survivors exhibit a phenotype of sarcopenic obesity with increased fat but low muscle mass. This abnormal body composition is observed despite normalization of the hypermetabolism found in chronic disease and cannot be explained by overeating. The role of appropriate nutrition and physiotherapy after transplantation merits further investigation.
