Impact of glucocorticoids on the incidence of lupus-related major organ damage: a systematic literature review and meta-regression analysis of longitudinal observational studies

OBJECTIVE: In systemic lupus erythematosus (SLE), disease activity and glucocorticoid (GC) exposure are known to contribute to irreversible organ damage. We aimed to examine the association between GC exposure and organ damage occurrence. METHODS: We conducted a literature search (PubMed (Medline), Embase and Cochrane January 1966–October 2021). We identified original longitudinal observational studies reporting GC exposure as the proportion of users and/or GC use with dose information as well as the occurrence of new major organ damage as defined in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. Meta-regression analyses were performed. Reviews, case-reports and studies with <5 years of follow-up, <50 patients, different outcomes and special populations were excluded. RESULTS: We selected 49 articles including 16 224 patients, 14 755 (90.9%) female with a mean age and disease duration of 35.1 years and of 37.1 months. The mean follow-up time was 104.9 months. For individual damage items, the average daily GC dose was associated with the occurrence of overall cardiovascular events and with osteoporosis with fractures. A higher average cumulative dose adjusted (or not)/number of follow-up years and a higher proportion of patients on GC were associated with the occurrence of osteonecrosis. CONCLUSIONS: We confirm associations of GC use with three specific damage items. In treating patients with SLE, our aim should be to maximise the efficacy of GC and to minimise their harms

Susac Syndrome: Description of a Single-Centre Case Series

This study describes the clinical characteristics, diagnostic results, treatment regimens, and clinical course of a cohort of patients with Susac syndrome (SS). It is a retrospective observational study of all patients with the diagnosis of SS evaluated at the Hospital Clinic (Barcelona, Spain) between March 2006 and November 2020. Nine patients were diagnosed with SS. The median time from the onset of the symptoms to diagnosis was five months (IQR 9.0), and the median follow-up time was 44 months (IQR 63.5). There was no clear predominance of sex, and mean age of symptoms onset was 36 years (range 19-59). Six patients (67%) presented with incomplete classical clinical triad, but this eventually developed in six patients during the disease course. Encephalopathy, focal neurological signs, visual disturbances, and hearing loss were the most frequent manifestations. Brain magnetic resonance imaging showed callosal lesions in all patients. Most were in remission within two years. Only four patients met the proposed criteria for definite SS. When SS is suspected, a detailed diagnostic workup should be performed and repeated over time to identify the clinical manifestations that will lead to a definite diagnosis

Reliability of Visual Analog Scale and Numeric Rating Scale for the Assessment of Disease Activity in Systemic Lupus Erythematosus

OBJECTIVE: To determine the reliability of SLE patients\u27 disease activity measurements. METHODS: This was a cross-sectional study conducted (August 2016-December 2017) at 2 main public Peruvian hospitals, 1 with a comprehensive lupus care program. Patients assessed their disease activity with a visual analog scale (VAS) (0-100 mm) or a numerical rating scale (NRS) (0-4) before and after their physician\u27s (MD\u27s) assessment. Demographic and disease-related characteristics were recorded. Reliability of patients\u27 disease activity before and after MD\u27s assessment was determined using Spearman rank correlation. Factors possibly associated with this variability were examined with Spearman rank correlation and Mann-Whitney U test. RESULTS: Two hundred forty, mostly Mestizo, SLE patients were included; mean (SD) age and disease duration (diagnosis) were 34.9 (12.9) years and 10.1 (7.0) years, respectively. The Mexican version of the Systemic Lupus Erythematosus Disease Activity Index was 1.9 (2.7), and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index was 1.2 (1.5). The correlations between NRS and VAS before and after the MD\u27s assessment were ρ = 0.839; p \u3c 0.001; and ρ = 0.872; p \u3c 0.001, respectively. Visual analog scale and NRS were higher before than after the MD\u27s assessment (VAS 29.3 [26.5] and 26.5 [24.9], p = 0.052; and NRS (1.5 [1.2] and 1.3 [1.1], p = 0.003); only the comprehensive program explained this variability (p = 0.043). The reliability of VAS and NRS was ρ = 0.917 and ρ = 0.861, p \u3c 0.001, before and after for the comprehensive program and ρ = 0.710 and ρ = 0.785, p \u3c 0.001, for before and after for the regular program. CONCLUSIONS: Both VAS an NRS are highly reliable. Patients scored higher before than after their physicians\u27 assessment but that these differences were smaller for the patients in the comprehensive care program than in the regular one

Discrepant Perception of Lupus Disease Activity: A Comparison Between Patients\u27 and Physicians\u27 Disease Activity Scores

OBJECTIVE: The aim of this study was to compare patient and physician (MD) assessment of disease activity in systemic lupus erythematosus patients. METHODS: This cross-sectional study was conducted between August 2016 and December 2017 at 2 Peruvian hospitals. One group assessed disease activity using a visual analog scale (VAS, 0-100 mm) and the other one using a numerical rating scale (NRS, 0-4), before and after their MD\u27s visit. MDs assessed it with the Mexican Systemic Lupus Erythematosus Disease Activity (Mex-SLEDAI) (0-32) and with the SLICC/ACR Damage Index (SDI) for damage. Health-related quality of life was ascertained with the LupusQoL. Visual analog scale and NRS were compared using the Wilcoxon signed-rank test and the correlation between disease activity as assessed by the patient and the Mex-SLEDAI, SDI, and LupusQoL with the Spearman rank correlation. RESULTS: Two hundred forty patients were included; mean (SD) age at diagnosis was 34.9 (12.9) years; most patients were Mestizo. Disease duration was 10.1 (7.0) years. The Mex-SLEDAI was 1.9 (2.7) and the SDI 1.2 (1.5). Disease activity as assessed by the patient, either by VAS or NRS, did not correlate with the Mex-SLEDAI or the SDI. In contrast, patient assessment of disease activity, by VAS or NRS, significantly correlated with several components of the LupusQoL (physical health, pain, planning, emotional health, and fatigue). CONCLUSIONS: Physician\u27s and patient\u27s assessments of disease activity are discrepant; overall, patients score higher than their MDs. Patients score how they perceive the disease is affecting them, rather than disease activity per se. The VAS could be more useful than the NRS as a measurement of disease activity
