RESUMEN

OBJECTIVES: This study aimed to evaluate older people's experience of a COVID-19 partial lockdown (16 March-11 May 2020) in Lausanne, Switzerland. SETTING AND PARTICIPANTS: Community-dwelling participants of the Lausanne cohort (Lc65+) in 2020, aged 71-86 years (n=2642). DESIGN AND OUTCOME: This cross-sectional study was nested within the Lc65+ longitudinal study. A specific COVID-19 questionnaire was sent on 17 April 2020 to evaluate participants' experience of the lockdown (outcome). Multinomial logistic regression models were used to determine the sociodemographic, living environment, health and social factors associated. RESULTS: Out of 2642 participants, 67.8% described the lockdown as 'somewhat' difficult (reference group), 21.5% as 'not at all' difficult (positive) and 10.7% as 'very or extremely' difficult (negative). The relative risk of a positive experience was higher in participants living alone (relative risk ratio, RRR=1.93, 95% CI 1.52 to 2.46) or in a house (RRR=1.49, 1.03 to 2.16); lower in those who reported fear of falling (RRR=0.68, 0.54 to 0.86), functional difficulties (RRR=0.78, 0.61 to 0.99), feeling of loneliness (RRR=0.67, 0.49 to 0.91), unfamiliarity with communication technologies (RRR=0.69, 0.52 to 0.91), usual social support (RRR=0.71, 0.50 to 0.93), previous participation in group activities (RRR=0.74, 0.59 to 0.92) and among women (RRR=0.75, 0.59 to 0.95). The relative risk of a negative experience was higher in participants with fear of falling (RRR=1.52, 1.07 to 2.15), and lower in those who had a terrace/garden (RRR=0.66, 0.44 to 0.99) and owned a dog (RRR=0.32, 0.11 to 0.90). CONCLUSIONS: Only one in 10 participants experienced the lockdown as very or extremely difficult. Specific interventions targeting vulnerability factors, such as fear of falling, could lessen the impact of any future similar situation.

RESUMEN

In these times of COVID-19 pandemic, concern has been raised about the potential effects of SARS-CoV-2 infection on immunocompromised patients, particularly on those receiving B-cell depleting agents and having therefore a severely depressed humoral response. Convalescent plasma can be a therapeutic option for these patients. Understanding the underlying mechanisms of convalescent plasma is crucial to optimize such therapeutic approach. Here, we describe a COVID-19 patient who was deeply immunosuppressed following rituximab (anti-CD20 monoclonal antibody) and concomitant chemotherapy for chronic lymphoid leukemia. His long-term severe T and B cell lymphopenia allowed to evaluate the treatment effects of convalescent plasma. Therapeutic outcome was monitored at the clinical, biological and radiological level. Moreover, anti-SARS-CoV-2 antibody titers (IgM, IgG and IgA) and neutralizing activity were assessed over time before and after plasma transfusions, alongside to SARS-CoV-2 RNA quantification and virus isolation from the upper respiratory tract. Already after the first cycle of plasma transfusion, the patient experienced rapid improvement of pneumonia, inflammation and blood cell counts, which may be related to the immunomodulatory properties of plasma. Subsequently, the cumulative increase in anti-SARS-CoV-2 neutralizing antibodies due to the three additional plasma transfusions was associated with progressive and finally complete viral clearance, resulting in full clinical recovery. In this case-report, administration of convalescent plasma revealed a stepwise effect with an initial and rapid anti-inflammatory activity followed by the progressive SARS-CoV-2 clearance. These data have potential implications for a more extended use of convalescent plasma and future monoclonal antibodies in the treatment of immunosuppressed COVID-19 patients.

RESUMEN

Several studies published in 2020 showed new data supporting the prescription of statins in some old and very old patients. Despite the enthusiasm about SGLT-2 inhibitors, caution must remain in frail and dependent older diabetic patients who are not well represented in most studies. Antihypertensive treatment appears more beneficial when taken at night rather than in the morning but beware of the prescribing cascade of a diuretic when a new prescription of a calcium channel blocker. Biomarkers, including plasmatic biomarkers, are becoming increasingly important in the diagnostic strategy of neurocognitive disorders. Finally, fall prevention studies showed heterogeneous results but multimodal interventions remain mainstream.


Plusieurs études publiées en 2020 ont relancé le débat concernant la prescription de statines chez certaines personnes âgées et très âgées. Malgré l'enthousiasme concernant les inhibiteurs du SGLT2, la prudence reste de mise chez les patients diabétiques âgés vulnérables et, surtout dépendants, peu ou pas représentés dans les études. La prise nocturne d'un traitement antihypertenseur semble plus efficace que diurne, mais attention à la prescription en cascade d'un diurétique de l'anse lorsqu'un traitement anticalcique est initié. La place des biomarqueurs, y compris plasmatiques, dans la stratégie diagnostique se renforce. Si les études de prévention des chutes ont montré des résultats variables, l'approche interventionnelle multimodale reste la référence.

RESUMEN

BACKGROUND: Little information is available regarding the association between vulvar intraepithelial neoplasia grade 3 (VIN3) and Behçet's disease (BD). We report here concomitant VIN3 and genital ulcers in a patient with BD. CASE: A 44-year-old Caucasian woman with a history of BD, which had been evolving for 6 years, presented with ulcerated and papillomatous lesions on the vulva. Biopsies revealed a multifocal VIN3 positive for high-risk human papillomavirus (HPV) 33. Multiple biopsies were performed to exclude invasive cancer and VIN3 was treated with laser vaporization. CONCLUSION: We report clinical and anatomopathological features of a rare case of multifocal, high-risk, HPV-related VIN3. We also discuss the possible pathogenesis in the context of BD, featuring chronic ulceration and intrinsic or treatment-induced immunosuppression.
