Acute respiratory distress syndrome (ARDS) related to SARS-CoV-2 is likely due to a cytokine storm characterised by a major release of pro-inflammatory cytokines, including interleukin-6 (IL-6). Blocking excessive IL-6 production might be the key to the COVID-19-ARDS treatment. Beneficial effects of IL-6 blockade using a humanised anti-IL-6 receptor antibody, tocilizumab (TCZ) were previously reported in patients with COVID-19 related ARDS. The aim of the study was to study the variation over time of several biomarkers, demonstrated to be predictors of poor prognostic, in subjects successfully treated with TCZ for severe COVID-19. ⋯ In patients with COVID-19 acute respiratory distress syndrome, treatment with TCZ resulted in favourable evolution in 75% of the cases. Biomarkers of inflammation (CRP, ferritin, fibrinogen) decreased dramatically as early as the 4th day after TCZ injection. Lymphopenia, a predictor of poor prognostic, was reversed 6 days after TCZ injection.

Interstitial lung disease (ILD) is a leading cause of mortality in patients with connective tissue diseases (CTD). Lung transplantation has become a viable option for patients with end-stage CTD-ILD. However, patients with CTD are often considered suboptimal candidates for lung transplantation because of concerns of worse outcomes. We assessed post-transplant survival of patients with CTD-ILD compared to patients with idiopathic pulmonary fibrosis (IPF). ⋯ Long-term post-transplant survival in Northern Spanish patients with CTD-ILD is reduced compared with IPF.

Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is a group of systemic vasculitides that predominantly affect small vessels, including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). Pulmonary involvement is frequently observed in AAV patients, with various possible phenotypes in the different diseases. In the last years, among the possible types of lung involvement, a growing interest has been addressed to the interstitial lung disease (ILD). ⋯ Currently, immunosuppressive therapy is considered also as a possible treatment of ILD. However, a careful evaluation of progression and severity of lung involvement, should guide the treatment decision in the single patient. In this review, we discuss the available evidence on clinical features, diagnostic work-up, prognosis and management of AAV-ILD.

Autonomic dysfunction (AD) has been described in various chronic inflammatory diseases. Studies of AD in patients with familial Mediterranean fever (FMF) are inconclusive. We aimed to assess AD in a cohort of FMF patients. ⋯ FMF patients have AD in terms of symptoms and parasympathetic pupillomotor function. Dynamic pupillometry can provide additional information on autonomic regulation in patients with FMF.
