Vitiligo Treatment Impact score (VITs): development and validation of a vitiligo burden of treatment questionnaire using the ComPaRe Vitiligo e-cohort

BACKGROUND

Vitiligo management is challenging and requires long-term adherence of patients who often complain of the burden associated with treatment.

OBJECTIVE

To develop and validate a patient reported measurement of the burden of treatment in vitiligo.

METHODS

The study was nested within the ComPaRe Vitiligo e-cohort, an online e-cohort of vitiligo patients in France. Items were derived from a literature review and from the qualitative analysis of a survey using open-ended questions of 204 patients with Vitiligo. Construct validity of the resulting instrument was assessed by comparing the instrument's score to the Dermatology Life Quality Index (DLQI), Vitiligo Impact Patient score (VIPs) and Treatment Burden Questionnaire (TBQ) scores. Reliability was assessed by test-retest with 15 ± 10 days of interval between both assessments.

RESULTS

In total, 343 adult participants participated in the validation of the Vitiligo Treatment Impact score (VITs). The VITs is a 19-item questionnaire assessing the burden of treatment in patients with vitiligo with results suggesting four domains ('Finding a doctor', 'Phototherapy', 'Topical treatment' and 'Impact on outdoor activities and photoprotection'). The VITs total score was well correlated with the DLQI, VIP and TBQ scores. Agreement between test and retest was good (ICC 0.705, 95% CI 0.491-0.818).

CONCLUSIONS

We developed a patient reported measurement of the burden of treatment in vitiligo with good psychometric properties.

P–327 Patients’ perspectives on how to improve the management of endometriosis in France: The ComPaRe-Endometriosis cohort

Study question

How should endometriosis management be improved from the patient’s point of view?

Summary answer

One thousand endometriosis patients proposed 2,587 ideas to improve the management of endometriosis that reflect three main themes: diagnosis, care, and information on the disease.

What is known already

Endometriosis is a gynecologic condition affecting 10% of reproductive-age women. The disease causes severe pelvic pain and has a dramatic impact on women’s quality of life. A mean delay of 7 years was described between onset of symptoms and diagnosis. There is an urgent need to reduce this delay and to rethink endometriosis care in order to adopt a more comprehensive and patient-centered approach, as women are often dissatisfied with the care they receive.

Study design, size, duration

This study was carried out in a random sample of endometriosis patients participating in ComPaRe (Community of Patients for Research), a prospective e-cohort of adult chronic disease patients who will be followed-up for 10 years. Participants complete monthly online questionnaires about their life with their disease(s). Recruitment began in January 2017 and is still ongoing, with currently 44,000 participants, including 10,000 endometriosis patients in the ComPaRe-Endometriosis sub-cohort.

Participants/materials, setting, methods

We selected a random sample of 1,000 participants in ComPaRe-Endometriosis, forming 3 equal groups of age (<25, 25–45, >45 years old) and education (<12, 12–14, >14 years). We conducted a qualitative study to gather their ideas for improving the management of their disease. Participants were asked: “If you had a magic wand, what would you change in your health care?”. One interviewer and two patients independently extracted ideas from the open-ended responses using thematic analysis.

Main results and the role of chance

Patients proposed a total of 2,587 ideas to improve the management of endometriosis, which we classified in three main themes: diagnosis, care, and information on the disease. To improve diagnosis, women proposed 724 ideas classified into 11 areas of improvement, including training of health professionals, taking symptoms seriously, improving the diagnosis process, and recognition of the disease by clinicians. To improve care, patients gave 1,677 ideas classified into 71 areas of improvement. For example, they asked for a better pain management, more listening from caregivers, the reimbursement of care or medical treatments, help in accessing clinicians that are expert in endometriosis, and reduced waiting times for medical appointments and exams. Finally, to improve information on the disease, participants suggested 186 ideas classified into 5 areas of improvement, covering more explanation about the disease, public recognition of endometriosis and general awareness, and more research and more explanation of research results.

Limitations, reasons for caution

The results were reviewed by three people in order to reduce the margin of interpretation in the analysis of this open-ended question, but some subjectivity remains. Generalizability may be difficult because the results are linked to the specificities of the French model of care.

Wider implications of the findings: Through the many ideas proposed by patients, we identified a total of 87 areas for improvement in endometriosis diagnosis, care, and information. These results reflect patients’ expectations in terms of management of their disease and will be useful to design a better global care for endometriosis from the patients’ perspective.

Late-onset neutropenia after treatment with rituximab for rheumatoid arthritis and other autoimmune diseases: data from the AutoImmunity and Rituximab registry

Objectives

To evaluate the prevalence of late-onset neutropenia and its complications in patients treated with rituximab (RTX) for rheumatoid arthritis (RA) and other autoimmune diseases (AIDs) in a prospective registry.

Methods

The AutoImmunity and Rituximab registry is an independent 7-year prospective registry promoted by the French Society of Rheumatology. For each episode of neutropenia, data were validated by the clinician in charge of the patient.

Results

Among 2624 patients treated with RTX for refractory AIDs, and at least 1 follow-up visit (a total follow-up of 4179 patient-years in RA and 987 patient-years in AIDs), late-onset neutropenia was observed in 40 patients (25 RA (1.3% of patients with RA, 0.6/100 patient-years), and AIDs in 15 (2.3% of patients with AIDs, 1.5/100 patient-years)). 6 patients (15%) had neutrophils <500/mm³, 8 (20%) had neutrophils between 500 and 1000/mm³, and 26 (65%) had neutrophils between 1000 and 1500/mm³. Neutropenia occurred after a median period of 4.5 (3–6.5) months after the last RTX infusion in patients with RA, and 5 (3–6.5) months in patients with AIDs. 5 patients (12.5%), 4 of them with neutrophils lower than 500/mm³, developed a non-opportunistic serious infection and required antibiotics and granulocyte colony-stimulating factor injections, with a favourable outcome. After resolution of their RTX-related neutropenia, 19 patients (47.5%) were re-treated, and neutropenia reoccurred in 3 of them.

Conclusions

Late-onset neutropenia might occur after RTX and may result in serious infections. Thus, monitoring of white cell count should be performed after RTX. However, in this large registry of patients with AIDs, the frequency of RTX-induced neutropenia was much lower than that previously reported in patients treated for blood malignancies or AIDs.

Predictive risk factors of serious infections in patients with rheumatoid arthritis treated with abatacept in common practice: results from the Orencia and Rheumatoid Arthritis (ORA) registry

OBJECTIVES

Little data are available regarding the rate and predicting factors of serious infections in patients with rheumatoid arthritis (RA) treated with abatacept (ABA) in daily practice. We therefore addressed this issue using real-life data from the Orencia and Rheumatoid Arthritis (ORA) registry.

METHODS

ORA is an independent 5-year prospective registry promoted by the French Society of Rheumatology that includes patients with RA treated with ABA. At baseline, 3 months, 6 months and every 6 months or at disease relapse, during 5 years, standardised information is prospectively collected by trained clinical nurses. A serious infection was defined as an infection occurring during treatment with ABA or during the 3 months following withdrawal of ABA without any initiation of a new biologic and requiring hospitalisation and/or intravenous antibiotics and/or resulting in death.

RESULTS

Baseline characteristics and comorbidities: among the 976 patients included with a follow-up of at least 3 months (total follow-up of 1903 patient-years), 78 serious infections occurred in 69 patients (4.1/100 patient-years). Predicting factors of serious infections: on univariate analysis, an older age, history of previous serious or recurrent infections, diabetes and a lower number of previous anti-tumour necrosis factor were associated with a higher risk of serious infections. On multivariate analysis, only age (HR per 10-year increase 1.44, 95% CI 1.17 to 1.76, p=0.001) and history of previous serious or recurrent infections (HR 1.94, 95% CI 1.18 to 3.20, p=0.009) were significantly associated with a higher risk of serious infections.

CONCLUSIONS

In common practice, patients treated with ABA had more comorbidities than in clinical trials and serious infections were slightly more frequently observed. In the ORA registry, predictive risk factors of serious infections include age and history of serious infections.

Safety of surgery after rituximab therapy in 133 patients with rheumatoid arthritis: data from the autoimmunity and rituximab registry

OBJECTIVE

We used data from the AutoImmunity and Rituximab (AIR) registry to investigate the safety of surgery for patients with rheumatoid arthritis receiving rituximab (RTX) in routine care.

METHODS

Data for patients included in the AIR registry and undergoing surgery during the year following an infusion of RTX were reviewed to describe the frequency of postsurgical complications, compare patients with and without complications, and identify factors associated with complications.

RESULTS

We examined data for 133 patients with a known date of surgery and at least 1 followup visit, corresponding to 140 procedures, including 94 orthopedic surgeries (67%) and 23 abdominal surgeries (16.5%). The median delay between surgery and the last RTX infusion was 6.4 months (interquartile range 4.3– 8.7 months), without any difference between patients with and without complications. Nine patients (6.7%) experienced 12 complications (8.5%), including 8 surgical site infections (5.7%) and 1 death due to septic shock. Postoperative complications occurred after 4.3% of abdominal surgeries (1 of 23) and 7.4% of orthopedic surgeries (7 of 95). On univariate analysis, spine surgery was associated with postoperative complications (P = 0.048).

CONCLUSION

In common practice, the risk of complications may be more important in case of spine surgery, but does not seem to be linked to the time between the last RTX infusion and surgery.

Positivity for anti-cyclic citrullinated peptide is associated with a better response to abatacept: data from the 'Orencia and Rheumatoid Arthritis' registry

OBJECTIVES

Very limited data are available regarding the efficacy of abatacept (ABA) in real life. The aims of this study were to determine the efficacy of ABA in rheumatoid arthritis and predicting factors of efficacy in common practice.

METHODS

The Orencia and Rheumatoid Arthritis" (ORA) prospective registry, promoted by the French Society of Rheumatology, has included 1003 patients with RA.

RESULTS

773 patients had already fulfilled the 6-month follow-up visit. Only 21.3% of patients would have fulfilled inclusion criteria used in pivotal controlled trials. The European League Against Rheumatism (EULAR) response, was observed in 330 (59.1%) of the 558 assessed patients (good response: 20.4%, moderate response: 38.7%) and was similar in patients who did and in patients who did not fulfill inclusion criteria of controlled trials. Among EULAR responders, initial 28-joint disease activity score (5.4 (4.7-6.5) in responders vs 4.9 (4.0-6.0) in non responders, p< 0.0001), the proportion of rheumatoid factor (75.6% vs 66.7%, p= 0.03) and the proportion of anti-cyclic citrullinated peptide antibody (anti-CCP)-positivity (75.9% vs 62.2%, p= 0.001) were significantly higher. In multivariate analysis adjusted on initial 28-joint disease activity score and CRP, anti-CCP positivity was associated with EULAR response (OR=1.9;95% CI=1.2 to 2.9, p=0.007), but not rheumatoid factor (OR=1.0;95% CI=0.6 to 1.6, p=0.9). Anti-CCP positivity was also significantly associated with a higher ABA retention rate at 6 months.

CONCLUSIONS

Real life efficacy of ABA in the ORA registry was similar as that reported in clinical trials. Anti-CCP positivity was associated with a better response to ABA, independently from disease activity.
