[Renal manifestations of syphilis]. / Manifestations rénales de la syphilis.

Syphilis is an acquired or congenital systemic pathology, currently on the rise in Europe. The clinical manifestations of syphilis are not very specific and variable over time. In this case report, we describe two renal presentations of syphilis in patients followed in a Pre-Exposure Prophylaxis (PrEP) program for the prevention of HIV infection. The specificity of the renal involvement of syphilis, the diagnostic and the therapeutic management will be discussed in this article.

La syphilis est une pathologie systémique acquise ou congénitale, actuellement en recrudescence en Europe. Les manifestations cliniques de la syphilis sont souvent peu spécifiques et variables au cours du temps. Nous décrivons ici deux présentations rénales de la syphilis survenues chez des patients suivis dans un programme de Pre-Exposure Prophylaxis (PrEP) de prévention contre l'infection VIH. La spécificité de l'atteinte rénale de la syphilis, la mise au point diagnostique et la prise en charge thérapeutique seront discutées dans cet article.

Long-term clinical follow-up of patients suffering from moderate-to-severe COVID-19 infection: a monocentric prospective observational cohort study.

OBJECTIVES: Various symptoms and considerable organ dysfunction persist following infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Uncertainty remains about the potential mid- and long-term health sequelae. This prospective study of patients hospitalized with coronavirus disease 2019 (COVID-19) in Liège University Hospital, Belgium aimed to determine the persistent consequences of COVID-19. METHODS: Patients admitted to the University Hospital of Liège with moderate-to-severe confirmed COVID-19, discharged between 2 March and 1 October 2020, were recruited prospectively. Follow-up at 3 and 6 months after hospital discharge included demographic and clinical data, biological data, pulmonary function tests (PFTs) and high-resolution computed tomography (CT) scans of the chest. RESULTS: In total, 199 individuals were included in the analysis. Most patients received oxygen supplementation (80.4%). Six months after discharge, 47% and 32% of patients still had exertional dyspnoea and fatigue. PFTs at 3-month follow-up revealed a reduced diffusion capacity of carbon monoxide (mean 71.6 ± 18.6%), and this increased significantly at 6-month follow-up (P<0.0001). Chest CT scans showed a high prevalence (68.9% of the cohort) of persistent abnormalities, mainly ground glass opacities. Duration of hospitalization, intensive care unit admission and mechanical ventilation were not associated with the persistence of symptoms 3 months after discharge. CONCLUSION: The prevalence of persistent symptoms following hospitalization with COVID-19 is high and stable for up to 6 months after discharge. However, biological, functional and iconographic abnormalities improved significantly over time.
