there is a need for quantitative composite measures that have an acceptable validation&#46; Designing these composite measures is a challenge&#44; given the multisystem involvement in SLE and its extensive variability&#46; At present&#44; there are multiple tools with varying degrees of validation&#44; although none has been accepted as the only measure recommended internationally&#46; Choosing the most appropriate measure in each case mainly depends on the context in which it will be used and the question one wants to answer in terms of disease assessment&#46;</p><p id="par0275" class="elsevierStylePara elsevierViewall">Broadly speaking&#44; there are 2 types of activity indices&#44; those which function as global measures &#40;such as ECLAM&#44; SLAM&#44; SLEDAI and LAI&#41; and those that give a specific score for each organ system &#40;BILAG&#41;&#46;</p><p id="par0280" class="elsevierStylePara elsevierViewall">The global indices are considered useful to compare cohorts of patients with SLE&#44; as they are simpler to implement and therefore more useful in population studies&#46; They can also be used to define inclusion criteria for RCTs or response criteria for treatment&#46; But these indices do not give information on the degree of activity in a specific organ&#44; for which indices of organ&#47;system would be most useful&#46;</p><p id="par0285" class="elsevierStylePara elsevierViewall">In terms of implementation&#44; most of these indices are complex and require information from the clinical history and physical examination&#46; The index takes that takes longer to implement is the BILAG&#44; and the LAI and SLAQ are the simplest to apply&#46; Internal consistency was assessed only in the BILAG and SLAQ&#44; being higher in the latter&#46; Regarding the interobserver reliability&#44; the index showed a higher ICC was the SLEDAI &#40;ICC<span class="elsevierStyleHsp" style=""></span>&#61;<span class="elsevierStyleHsp" style=""></span>0&#46;79&#41;&#46; The interobserver reliability was assessed in a very heterogeneous way across studies&#44; making it difficult to compare the indices&#46; This aspect of validation is not required in the indexes answered by the patient&#46;</p><p id="par0290" class="elsevierStylePara elsevierViewall">Construct validity was the most studied part of the validation for most indices&#44; with similar results&#46; It is difficult to establish a gold standard as a reference to assess disease activity&#46; To assess criterion validity&#44; in some studies the gold standard was change of treatment and&#44; in others&#44; the PGA&#46; Use of the PGA as a gold standard has certain problems&#44; since several studies have shown that there is a very low degree of agreement between doctors when assessing the disease activity in patients with SLE&#46;<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1&#44;27</span></a> Other studies used as gold standard another index already described in the literature&#44; with which the new index was compared and evaluated&#46; Most indices correlate acceptably with each other&#46;<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">22</span></a></p><p id="par0295" class="elsevierStylePara elsevierViewall">Finally&#44; the index that shows a greater sensitivity to change is the ECLAM&#46;</p><p id="par0300" class="elsevierStylePara elsevierViewall">Some important aspects to consider is that the activity indexes should only rate aspects that are directly related to the disease&#46; The SLAM and BILAG collected manifestations that appear in the last month&#44; while others collected manifestations in the last 10 days&#46; Some indexes include laboratory variables and it is important to note that there are patients with active SLE who have no laboratory abnormalities&#46; For example&#44; only 60&#37; of patients have positive anti-dsDNA antibodies during the course of the illness&#46;<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">50</span></a></p><p id="par0305" class="elsevierStylePara elsevierViewall">A critique of these indices could be that most of them have been validated in the context of long-term cohorts instead of RCT&#46;<a class="elsevierStyleCrossRef" href="#bib0255"><span class="elsevierStyleSup">51</span></a> Even so&#44; in 1998&#44; one of the OMERACT objectives was to preliminarily define minimum variables to be included in the evaluation of patients with SLE&#44; both for RCTs and longitudinal cohort of long-term activity&#44; and these were illness&#44; injury&#44; quality of life and toxicity&#47;adverse effects&#46;<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">52</span></a></p><p id="par0310" class="elsevierStylePara elsevierViewall">The concept of damage in SLE has become an important outcome measure&#44; as it not only predicts mortality also functional capacity and health resource utilization&#46;<a class="elsevierStyleCrossRefs" href="#bib0265"><span class="elsevierStyleSup">53&#8211;55</span></a> In this review&#44; three measures of injury have been identified&#44; one that is completed by the doctor&#44; the SDI&#44; and 2 to be completed by the patient LDIQ and BILD&#46; The 2 self-administered measures of damage showed a good correlation with the extent to which the physician measured was considered the gold standard&#46;</p><p id="par0315" class="elsevierStylePara elsevierViewall">In conclusion&#44; most composite indices to assess disease activity in SLE patients have been validated and are comparable&#46; Although complex&#44; when applied in clinical practice&#44; these indices facilitate the collection of relevant clinical information quantitatively and EULAR recommends their use to monitor patients&#46;<a class="elsevierStyleCrossRef" href="#bib0280"><span class="elsevierStyleSup">56</span></a> The use of composite indices to assess both the activity and structural damage would assist in clinical practice to guide therapeutic decisions as objectively as possible&#46;<a class="elsevierStyleCrossRef" href="#bib0255"><span class="elsevierStyleSup">51</span></a> Furthermore&#44; the PGA exhibits great variability&#44; even among physicians with extensive experience treating patients with SLE&#44; not making it an ideal tool to assess activity&#46;</p><p id="par0320" class="elsevierStylePara elsevierViewall">Both the BILAG and SLEDAI are the indexes that have a more complete validation and are most commonly used in RCTs and cohort studies&#46; The ECLAM has the advantage of being the easiest to calculate and SLAM is the most sensitive to change&#44; since it is the only one that can gives a greater score to high severity&#46; The SLAQ is a patient answered index that exhibits good correlation with SLAM&#44; from which it derives&#44; so it may be a good alternative for patient visit in which there is less time to spend per patient or in population studies&#46;</p></span><span id="sec0115" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0155">Ethical Responsibilities</span><span id="sec0120" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0160">Protection of people and animals</span><p id="par0350" class="elsevierStylePara elsevierViewall">The authors declare that no experiments were performed on humans or animals for this investigation&#46;</p></span><span id="sec0125" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0165">Data confidentiality</span><p id="par0355" class="elsevierStylePara elsevierViewall">The authors declare that no patient data appears in this article&#46;</p></span><span id="sec0130" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0170">Right to privacy and informed consent</span><p id="par0360" class="elsevierStylePara elsevierViewall">The authors have obtained the informed consent of the patients and&#47;or subjects mentioned in the article&#46;
