Objective: The aim of the present study was to detect preclinical changes in SLE patients in retinal microvascularization or retinal and optical nerve structure by optical coherence tomography. Methods: This cross-sectional, single-centre study aimed to describe structural changes [macular and retinal nerve fibre layer (RNFL) thickness] by structural spectral-domain optical coherence tomography (SD-OCT) and perifoveal vascular [vessel density (VD) and vascular perfusion (VP) and foveal avascular zone (FAZ) structural parameters] findings by OCT angiography (OCTA) in 78 SLE patients and 80 healthy volunteers. In addition, we analysed their association with clinical and laboratory parameters, medications received, disease duration, and SLE activity and damage. Results: Structural parameters by SD-OCT and perifoveal vascular parameters by OCTA were decreased in SLE patients compared with controls. OCTA parameters (VD, VP and FAZ circularity) and macular thickness were also decreased in patients with longer disease duration (>10 years). The presence of aPLs was associated with a decreased RNFL thickness, mainly in the inferior quadrants. Patients developing APS also showed decreased RNFL thickness and OCTA flow changes. SD-OCT and OCTA results were not associated with disease activity. Foveal structural parameters were lower in patients with higher damage score. Conclusion: SD-OCT and OCTA can detect preclinical structural and microcirculatory changes in SLE patients. Structural and perifoveal vascular macular changes in SLE patients are related to disease duration. Macular structural parameters were impaired in patients with higher disease damage. APS seems to be associated with preclinical damage to the optic nerve and impairment of the perifoveal microvasculature.

Background: Because of the efficacy and good safety profile of antimalarials in systemic lupus erythematosus (SLE), hydroxychloroquine (HCQ) is currently recommended in all SLE patients. However, patients’ compliance was reported as suboptimal. This study aims to elucidate the reasons for discontinuing antimalarials in a large series of SLE patients followed in a single centre during the last 50 years. Material and methods: Among all patients diagnosed between 1968 and 2017 at our reference centre, retrospective data were obtained from electronic medical records of SLE patients consecutively visited during 2015–2017 and controlled for at least 1 year. Demographic, clinical, laboratory and therapeutic data at disease onset and during the follow-up in the whole cohort and differences between SLE patients discontinuing and continuing on antimalarials were analysed. Results: Five-hundred thirty-nine patients followed during a median of 19 years were analysed. Median age at disease diagnosis was 29 years and 91.8% were women. Antimalarials were initiated by 521 (96.7%) patients and 18 (3.3%) cases did not start them mainly because of a quiescent or life-threatening SLE disease. In the 129 (24.7%) patients starting antimalarials with subsequent discontinuation, median treatment duration was 8.4 years. The main reason leading to treatment cessation was drug toxicity in 97 (18.6%) patients, of which macular toxicity was the most frequent adverse effect (n = 80; 15.3%). Treatment was stopped because of patient’s preference in 13 (2.5%) cases. The factors independently associated with antimalarial discontinuation were age at the end of follow-up (OR 1.130, 95% CI 1.005–1.269, p = 0.040), duration on antimalarials (OR 0.872, 95% CI 0.841–0.903, p < 0.001), presence of hepatitis C virus infection (HCV) (OR 13.948, 95% CI 1.321–147.324, p = 0.028) and anti-β2-glycoprotein 1 antibodies (OR 2.275, 95% CI 1.146–4.517, p = 0.019). Conclusions: In our 50 years-experience, almost all SLE patients underwent antimalarials. These drugs are usually stopped because of adverse effects, particularly macular toxicity. After a long-term follow-up, patients’ compliance to antimalarials was considerably high in our SLE patients.

Objective: To compare multimodal structural and functional diagnostic methods in patients with systemic lupus erythematosus (SLE) treated with hydroxychloroquine, to identify the best complementary approach for detecting subclinical retinal toxicity. Methods: A cross-sectional, unicentric study was conducted on patients with SLE treated with hydroxychloroquine. Each patient underwent a comprehensive ophthalmic evaluation, comprising structural tests (spectral-domain optical coherence tomography (SD-OCT), en face OCT, en face OCT angiography (OCTA), fundus autofluorescence (FAF)) and functional tests (automated perimetry for visual field (VF) testing, multifocal electroretinography (mfERG)). A diagnosis of macular toxicity required the presence of abnormalities in at least one structural and functional test. The Kappa Concordance Index was used to assess the concordance among the different tests in detecting potential macular toxicity-associated alterations. Results: Sixty-six patients with SLE (132 eyes) were consecutively enrolled. Four (6.1%) patients developed subclinical hydroxychloroquine-induced retinal toxicity without visual acuity impairment. The proportion of abnormal results was 24% for both en face OCT and en face OCTA. Regarding functional analysis, VF was less specific than mfERG in detecting subclinical retinal toxicity (VF specificity 47.5%). En face OCT and en face OCTA structural findings showed better concordance, with a kappa index >0.8, and both identified the same cases of toxicity as FAF. Conclusion: Although structural OCT and VF are frequently used to screen for hydroxychloroquine-induced retinal toxicity, our findings suggest that a combination of mfERG, en face OCT and en face OCTA could improve the diagnostic accuracy for subclinical retinal damage. This study emphasises the importance of a multimodal imaging strategy to promptly detect signs of hydroxychloroquine-induced retinal toxicity.

Background Unprotected and fragile elderly people in nursing homes experienced the highest mortality rates during the initial coronavirus disease 2019 (COVID-19) pandemic. Objective Our aim was to study the role of two oral anti-inflammatory drugs, colchicine and prednisone, in elderly patients with COVID-19 in geriatric centers. Methods A phase II/III, randomized, controlled, multicenter clinical trial was performed in a geriatric population comparing the efficacy and safety of an oral combination of prednisone (60 mg/day for 3 days) and colchicine (at loading doses of 1–1.5 mg/day for 3 days, followed by 0.5 mg/day for 11 days) with the standard treatment, based on intravenous dexamethasone. Primary endpoints assessed the efficacy in reducing death or the modified endpoint death/therapeutic failure to the study drugs over a 28-day period, while secondary endpoints included safety, laboratory changes, and additional therapies used. Results Fifty-four patients (35 female/19 male) were enrolled, 25 (46.3%) of whom were allocated to the experimental arm and 29 (53.7%) to the control arm. At day 28, no differences in deaths were observed. The combination of mortality or therapeutic failure occurred in 12 (45.13%) patients receiving dexamethasone and 6 (28.13%) patients receiving colchicine/prednisone, resulting in a reduction of risk difference (RD) of − 17% (p = 0.17), with an average reduction of 39% (risk ratio [RR] 0.61) in patients receiving colchicine/prednisone (p = 0.25). Control patients received higher amounts of additional glucocorticoids (p = 0.0095) over a longer time frame (p = 0.0003). Colchicine/prednisone significantly reduced ferritin levels at day 14, as well as d-dimer and lactate dehydrogenase (LDH) levels at day 28. Adverse events were similar in both groups. Conclusions The combination colchicine/prednisone compared with intravenous dexamethasone has shown a remarkable trend to increase disease survival over a 28-day period in elderly patients requiring oxygen therapy in geriatric centers, without safety issues.
