The improvement of health-related quality of life (HRQoL) is one of the treatment goals of a patient-centred medical therapy. HRQoL in patients with Crohn's disease (CD) can be measured by the EQ-5D questionnaire (EQ-5D). It comprises a descriptive system (EQ-5D d.s.) covering health-related impairment in five dimensions and a visual analogue scale (EQ-VAS). The aim of the study was to investigate HRQoL in CD patients treated with different immunosuppressive therapies during 9 months of follow-up in clinical routine.
In this ongoing prospective observational study patients with moderate to severe CD receiving conventional immunosuppressive therapy (i.e. systemic corticosteroids [CS] and/or immunosuppressants [IMM]) in clinical routine, but naïve to anti-TNF therapy are followed for 9 months. HRQoL status using the EQ-5D, disease severity according to investigator, and current medical treatment is recorded at baseline, month 3, 6, and 9. During the study patients are permitted to switch to anti-TNF or other immunosuppressive therapy. The mean change of EQ-5D scores from baseline to month 9 of the study were compared between different immunosuppressive treatments using the Mann–Whitney U test.
In total, 161 IBD centres across Germany participate in the study. As of February 2012, complete documentation was available for 350 patients for preliminary analysis. At baseline 64.9% of patients received CS of any dose (mono or combination therapy with IMM), and 35.1% an IMM monotherapy, respectively. At baseline EQ-5D d.s. and EQ-VAS scores were higher in patients on IMM monotherapy compared with patients on CS mono or combination therapy (e.g. mean EQ-VAS: 76.3 vs 70.5, p < 0.005). 38% of patients with CS use at baseline discontinued CS treatment during the study, while an anti-TNF therapy was started in 19% of all patients and in 24% of patients with baseline CS use. Significant EQ-5D d.s. and EQ-VAS improvements were seen in anti-TNF patients compared with patients under non-biological therapy at month 9 (e.g. mean EQ-VAS change at month 9 from baseline: 12.51 vs 2.42; p < 0.001). Patients on combined IMM with anti-TNF agents showed significant improvements in EQ-5D d.s. and EQ-VAS scores compared with patients on IMM alone within 9 months.
Anti-TNF therapy (alone or in combination with IMM) was associated with significantly HRQoL improvements in German CD patients compared with patients treated with IMM monotherapy.
