Abstract
OBJECTIVES Infection by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19) presents occasionally with an aberrant autoinflammatory response, including the presence of elevated circulating autoantibodies in some individuals. Whether the development of autoantibodies against self-antigens affects COVID-19 outcomes remains unclear. To better understand the prognostic role of autoantibodies in COVID-19, we quantified autoantibodies against 23 markers that are used for diagnosis of autoimmune disease. To this end, we used serum samples from patients with severe [intensive care unit (ICU)] and moderate (ward) COVID-19, across two to six consecutive time points, and compared autoantibody levels to uninfected healthy and ICU controls. METHODS Acute and post-acute serum (from 1 to 26 ICU days) was collected from 18 ICU COVID-19-positive patients at three to six time points; 18 ICU COVID-19-negative patients (sampled on ICU day 1 and 3); 21 ward COVID-19-positive patients (sampled on hospital day 1 and 3); and from 59 healthy uninfected controls deriving from two cohorts. Levels of IgG autoantibodies against 23 autoantigens, commonly used for autoimmune disease diagnosis, were measured in serum samples using MSD® U-PLEX electrochemiluminescence technology (MSD division Meso Scale Discovery®), and results were compared between groups. RESULTS There were no significant elevations of autoantibodies for any of the markers tested in patients with severe COVID-19. CONCLUSIONS Sample collections at longer time points should be considered in future studies, for assessing the possible development of autoantibody responses following infection with SARS-CoV-2.

Abstract
BACKGROUND AND PURPOSE The therapeutic scenario of X-linked adrenoleukodystrophy (X-ALD) is rapidly changing. Whereas the disease is well characterized in men, the condition remains to be fully clarified in women carrying ATP binding cassette subfamily D member 1 (ABCD1) variants. Specifically, data on clinical progression are needed, in order to recommend any appropriate management. The objective of this study was to outline the natural history of a cohort of untreated ABCD1 heterozygous female carriers. METHODS Longitudinal data from a single-center population of 60 carriers were retrospectively reviewed. Demographics, anthropometrics, serum very long chain fatty acid (VLCFA) levels, clinical parameters and the Adult ALD Clinical Score (AACS) were collected from every recorded visit in a 7-year period and analyzed to define the phenotype modifications, to determine factors associated with clinical features, and to estimate the annual progression rate and the subsequent sample size for interventional trials. RESULTS Thirty-two patients were eligible for the study, and 59.4% were symptomatic at baseline. Clinical severity worsens with age which increases risk of symptom onset, the cut-off of 41 years being crucial for phenoconversion. VLCFA levels were not predictive and did not change over time. Symptomatic carriers were followed up for 3.45 ± 2.1 years. The AACS increased at an annual rate of 0.24 points. The estimated sample size for 30% reduction in annual progression at 80% power was 272. CONCLUSIONS This study provides data on the natural disease progression of untreated ABCD1 heterozygous female carriers, demonstrating the relevance of aging. The estimated annual increase of the AACS will be useful for future interventional studies.

Abstract
Graves' orbitopathy (GO) is the most common and important extrathyroidal manifestation of Flajani-Basedow-Graves' disease, with autoimmune etiology. In most cases they are mild forms, in 3-5% they are severe and progressive. For therapeutic purposes, it is classified according to the severity (mild, moderate-severe or sight threatening), to the activity (active if clinical activity score is >=3), and to the impact on quality of life. The choice of medical or surgical therapy depends on the activity of the disease. Therapy for mild GO consists of abolition of risk factors, local treatments, oral administration of selenium. Therapy for moderate-severe and active GO consists of administration of intravenous, oral, topic and local (retrobulbar, peribulbar and subconjunctival) glucocorticoids (GC). The therapy of choice, after careful selection of patients, is pulse therapy with intravenous GC, with 79% of response. Orbital radiotherapy is effective in 60% of cases; diabetes mellitus and hypertension are absolute contraindications. Contemporary administration of oral GC and orbital radiotherapy are more effective than single therapies. Marginal and not validated therapies are cyclosporine, somatostatin analogues, TNF-a inhibitors and rituximab. The treatment for dysthyroid optic neuropathy (DON) consists of combination of steroids, orbital radiotherapy and, if necessary, orbital decompression surgery. The surgical therapies are orbital decompression and rehabilitative surgery.
