[Epidemiological data and medical care situation of patients with chronic inflammatory diseases in Germany : Real-world evidence on prevalence, disease combinations, care]. / Epidemiologische Daten und medizinische Versorgungssituation von Patienten mit chronischen Entzündungserkrankungen in Deutschland : Real-World-Evidenz zu Prävalenz, Erkrankungskombinationen, Versorgung.

BACKGROUND: Chronic inflammatory diseases (immune-mediated inflammatory diseases, IMID) can overlap or occur simultaneously due to clinical similarities. The resulting utilization of heathcare structures has not yet been investigated across disciplines but is of potential importance for optimizing the treatment of patients with IMID. AIM OF THE WORK: Analysis of epidemiological data including utilization of care services in patients with selected IMIDs: psoriasis, psoriatic arthritis (PsA), rheumatoid arthritis (RA), ankylosing spondylitis, ulcerative colitis, Crohn's disease and connective tissue disease. MATERIAL AND METHODS: In a retrospective cross-sectional analysis based on health insurances accounting data with a sample of approximately 4 million insured persons, the prevalence of the abovementioned IMID and the frequency of IMID combinations were analyzed based on documented diagnoses (ICD-10 GM). The frequency of hospitalizations and utilization of outpatient physician contacts was recorded in predefined specialist disciplines (general medicine, dermatology, gastroenterology, rheumatology) and compared with an age-adjusted and gender-adjusted reference population. RESULTS: A total of 188,440 patients had at least 1 of the IMID diagnoses analyzed (4.7%), with an age peak of 61-70 years. The highest prevalence was observed for psoriasis (1.85%), followed by rheumatoid arthritis (1.38%). Combinations with at least one other IMID were relatively common (29%), with this being most common in patients with psoriatic arthritis (82.9%, of which 68.2% had psoriasis), followed by ankylosing spondylitis (27.5%) and Crohn's disease (21.6%). Compared to the reference population, patients with IMID were hospitalized more often and more frequently utilized the outpatient disciplines. DISCUSSION: The study results describe that IMIDs occur in combination and that the patients make comparatively more use of care structures of different disciplines. A multidisciplinary approach could increase the efficiency of care; an evaluation is still pending.

Ustekinumab Is Rapid-Acting and Is an Effective Long-Term Treatment for Patients with Active Psoriatic Arthritis: Real-World Evidence from the Non-interventional SUSTAIN Study.

INTRODUCTION: Psoriatic arthritis (PsA) is a chronic, progressive disease that places a significant burden on patients and healthcare systems. The SUSTAIN study collected real-world evidence on long-term effectiveness, impact on quality of life, and safety of ustekinumab treatment for PsA. METHODS: SUSTAIN was a prospective, non-interventional study conducted in Germany. Patients with active PsA received ustekinumab for 160 weeks in routine clinical care, with assessments at baseline, week 4, and every 12 weeks thereafter. This analysis focuses on patients who remained in SUSTAIN until week 160. RESULTS: Of 337 patients enrolled, 129 were documented at week 160, of which 123 (95.3%) had received previous PsA medication, including biologics. Decreases from baseline to week 4 were observed for tender joint count (TJC, 8.0 to 5.8) and swollen joint count (SJC, 4.5 to 3.1); these decreases continued to week 28 and were maintained to week 160 (1.0 and 0.4, respectively). Similarly, skin assessments in patients with PsA and psoriasis revealed improvement at week 4, which continued to week 28, with a sustained effect until week 160. Similar patterns of response were observed for patient-assessed pain, sleep quality, and health scores. Improvements in TJC, SJC, Psoriasis Area and Severity Index, and affected body surface area were observed irrespective of the number of prior biologic therapies used. Minimal disease activity was achieved by 36 (31.9%) patients at week 28, and by 38 (33.6%) at week 52. Ustekinumab-related adverse events (AEs) and serious AEs were reported in 61 (47.3%) and 4 (3.1%) patients, respectively. At week 160, 100% of patients assessed ustekinumab tolerability as good or very good. CONCLUSIONS: In a real-world setting, patients with active PsA who received ustekinumab until 160 weeks (3 years), including those who received prior biologic therapies, had a rapid onset of effect and sustained response to treatment, with high tolerability.
