Conventional immunosuppressive therapies have radically transformed patient survivalin systemic lupus erythematosus SLE , but their use is associated with considerabletoxicity and a substantial proportion of patients remain refractory to treatment. Amore comprehensive understanding of the complexity of SLE immunopathogenesis hasevolved over the past decade and has led to the testing of several biologic agents inclinical trials. There is a clear need for new therapeutic agents that overcome theseissues, and biologic agents offer exciting prospects as future SLE therapies. Systemic lupus erythematosus SLE is a complex autoimmune rheumatic disease,characterized by unpredictable exacerbations and remissions. Theprevalence of SLE varies significantly in different ethnic groups. The overall prevalence of SLE in theUK is approximately 28 per , head of population, rising to approximately per, in Afro-Caribbean females [ 3 ].

About this book Often considered the prototypic autoimmune disease, Lupus is characterized by protean manifestations and affects a wide range of organ systems. Show all. From the reviews: Pages The Treatment of Lupus: To enable worldwide use of the PROs, translators assessed whether the questionnaires could be readily translated into three etymologically distinct languages German, Japanese, and Portuguese.

Based on the CD interviews, clinician input, and the translatability assessment, both PROs were revised. All interviews were recorded and transcribed for analysis; patient identifiable information was not included in any transcripts or analyses to ensure patient confidentiality.

All data were held in strict confidence in accordance with local, state, and federal law. A coding dictionary was developed and used in the thematic analysis. Each transcript was coded by one coder, then reviewed, summarized, and analyzed by a second coder. In addition to analyzing the data from the code book, representative quotes were reviewed. In this way, the rich patient narratives were converted into the final list of symptoms included in the SSD and the impacts described in the SIQ.

Safety was not assessed in the study; however, if patients reported an adverse event during the interview, they were instructed to report it to their healthcare provider; if relevant this was also reported to the study sponsor. SF a [ 11 ]. General population surveys and clinical trials to estimate disease burden and compare disease-specific benchmarks with general population norms.

Includes 19 items with generic and disease-specific components including symptoms and interference, cognitive and confidence and planning. Existing measures were also found to be insufficient as their development lacked substantial, documented input from patients with SLE e.

It was, therefore, concluded that the development of novel measures to evaluate symptoms and impacts would be of value for both clinical research and clinical practice. CD interviews to assess the content and clarity of the draft questionnaires were completed by a second group of 18 patients with SLE: At the final round of CD interviews there was little new information gained.

The majority of instructions and questions were found to be clear and concise and could be paraphrased correctly by most patients. As the majority of patients thought the 0—10 response scale was appropriate, and no patients indicated they would prefer a different set of response options, the point NRS was retained.

As a result of the translatability assessment, minor revisions were made to some questions and the instructions. People with lupus may experience a variety of symptoms.

Please indicate how severe the following lupus symptoms were at their worst in the past 24 hours by selecting one number. Sample questions from the SIQ: Seventeen patients completed CD interviews of the SIQ; due to the length of the questionnaire, it was not feasible to cognitively debrief all items, therefore, items with words or terms that were more complex or could potentially have more than one interpretation were focused upon.

For example, patients were debriefed on whether they considered the terms joint pain and joint stiffness to be the same, whether questions referring to both symptoms should be included, whether they should be kept as separate items and if they answered questions referring to them differently. Most revisions to the SIQ involved combining similar items or making minor wording changes to enhance translatability.

As such, a numeric rating of this impact would not necessarily be familiar or meaningful to patients. In addition, unlike the SSD, which is administered daily, the SIQ is administered weekly, as symptom impacts are less likely to change on a daily basis.

A Likert-type scale is appropriate for detecting these changes in impacts, as it is easy for respondents to understand and still sensitive enough to detect subtle changes [ 26 ]. Sample items are provided in Table 4. Existing PROs were either designed for different purposes e. Although the LupusPRO and LIT may have been developed in alignment with best measurement science, with content validity in the target population of interest and adequate measurement properties as required by the FDA, to the best of our knowledge, at the time of this study there was not comprehensive, publicly available, documented evidence that demonstrated this.

Patients reported that the PROs were clear, comprehensive, and relevant. Minor modifications to the draft PROs were made based on patient feedback, further clinician input, and an assessment of translatability.

Best scientific practices, as described in the FDA PRO Guidance [ 4 ], were followed throughout the development of both PROs, including an iterative development methodology and substantial patient input. Sample sizes were sufficient to support their development. We are confident that the CD sample size was sufficient and all items were evaluated satisfactorily; by the final round of reviewing there was little new information gained from the interviews.

Both Caucasian and African American patients were interviewed, and patients with a wide range of disease duration were included.

There were some instances where patients with mild SLE did not believe an item was relevant because they had not experienced it; therefore, it is important that future evaluation of the PROs includes patients with severe SLE. It may have been possible to obtain a more representative sample if a larger number of patients had been recruited instead of purposely selecting patients to generate a diverse sample for characteristics including age, race, disease severity and time since diagnosis.

Background demographic and clinical information was not collected from patients not eligible to participate or who declined to participate in the study, so it is unclear whether our patient population is representative of the total population approached. Another potential limitation of this study is that not all questions were asked of all patients during the cognitive debriefing of the instruments, therefore in some cases the sample size was smaller. Despite some limitations, primarily related to the characteristics of the study participants, using patient input to inform the content of the PROs enabled the inclusion of concepts that are most important and relevant to patients.

Importantly they were developed in accordance with the FDA PRO Guidance [ 4 ] and may be appropriate in a specified context to support claims in approved medical product labelling. Also, both PROs have been developed for electronic administration to enable patients to complete them regularly and with ease, and ensure more accurate reporting while minimizing missing data.

Previously, ePROs have been demonstrated to be a feasible and convenient tool for patients with chronic inflammatory disease [ 31 ].

Prior to use, it will be necessary to perform exploratory factor analysis for both PROs, in order to confirm the structure of each scale and develop scoring algorithms. Without this information, only item level data can be presented descriptively. In addition, the measurement properties of the questionnaires, including internal consistency reliability, test-retest reliability, construct validity, known groups validity, responsiveness to change over time, and an estimation of what change is clinically meaningful should be evaluated.

Development of a responder definition will support the interpretation of scale scores. We assessed the translatability of the PROs into three distinct languages; if it becomes necessary to translate the PROs in to other languages, further modifications may be required to ensure conceptual equivalence.

Following psychometric testing and adequate demonstration of the required measurement properties, these tools can be used in clinical research and clinical practice to assess the symptoms and impacts experienced by patients with SLE.
