Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)
Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters.
Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs).
Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001).
Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio
Quelles sont les causes de la mortalité périnatale et infantile élevée en Seine-Saint-Denis ? Consultation des professionnels du département par un processus Delphi
International audienceObjective: In Seine-Saint-Denis, stillbirth and infant mortality rates are markedly higher than in other French departments. Before implementing an audit on stillbirths and neonatal deaths in 2014, we carried out a Delphi consensus process with healthcare providers to generate research hypotheses.Materials and Methods: A Delphi process in 3 questionnaires was conducted in 2013 with 32 healthcare providers (pediatricians, obstetricians, general practitioners, midwives, social workers, psychologists, pediatric nurses) and user representatives. The first questionnaire asked open questions about why mortality rates were higher and possible solutions to remedy the situation. In subsequent questionnaires, the panel ranked factors identified in the first questionnaires by importance.Results: One hundred and thirty factors were identified from 42 pages of text responses in the first round. From these, the 75 most highly ranked were grouped into 14 main topics organized around three themes: 1) more underlying health problems in the population, 2) access and organization of care, 3) the health consequences of poor socioeconomic conditions. Coordination of care, provider and patient communication, and access to care were highlighted.Conclusion: The Delphi consensus process identified a wide range of hypotheses for the higher mortality in Seine-Saint-Denis which are adapted to the local context and based on the concerns of health practitioners.But: En Seine-Saint-Denis (SSD), les taux de mortinatalité et de mortalité infantile sont très élevés par rapport aux autres départements français. En amont d’un audit en 2014 sur tous les cas de mort-nés et de décès néonatals dans ce département, nous avions mené un processus Delphi auprès des professionnels y exerçant pour étayer les hypothèses de recherche.Matériel et méthodes: Un processus de consensus Delphi en 3 questionnaires a été mené en 2013 auprès de 32 professionnels et 3 représentants des usagers. Le premier questionnaire interrogeait les processus qui peuvent expliquer ces taux élevés et les solutions à proposer pour y remédier. Les 2 questionnaires suivants ont permis de classer les facteurs identifiés au 1er tour.Résultats: Cent trente facteurs ont été identifiés grâce aux 42 pages de réponses au 1er tour. Les 75 retenus par le panel ont ensuite été regroupés en 14 thèmes principaux organisés autour de trois axes : 1) l’état de santé maternelle et infantile en SSD ; 2) l’offre de soins dans le département et ses dysfonctionnements organisationnels ; 3) les conséquences sur sa santé des mauvaises conditions socioéconomiques d’une partie de la population. La coordination des soins, la communication entre les professionnels et les usagers et l’accès aux soins ont été particulièrement soulignés.Conclusion: L’enquête d’opinions par processus de consensus Delphi a permis d’identifier un large éventail d’hypothèses quant à la mortalité infantile et périnatale élevée en SSSD, adaptées aux préoccupations des praticiens
Ocular Histopathologic Features of Congenital Zika Syndrome
Congenital Zika syndrome (CZS) is known to be associated with severe malformations in newborns. Although microcephaly is the hallmark of this disease, the ocular findings are important given the severe visual impairment that has been observed in these patients. Regardless of the increased number of CZS cases reported, to date, no studies have described the ocular histopathologic findings of this entity.
To evaluate the presence of Zika virus (ZIKV) antigens and describe the associated ocular histopathologic features of 4 cases of CZS.
In this observational case series performed from June 19, 2015, through April 30, 2017, ocular tissue samples from 4 deceased fetuses with a diagnosis of CZS from the National Institute of Health in Colombia were sent to the Florida Lions Ocular Pathology Laboratory for evaluation.
The microscopic features of each specimen were described, and immunostaining was performed using a ZIKV NS2B protein antibody.
Ocular tissue samples from the 4 deceased fetuses (2 female, 2 male) ranging from 21.5 to 29 weeks' gestation with a diagnosis of CZS were studied. The 4 eyes manifested with pupillary membranes, immature anterior chamber angles, loss of pigment and thinning of the retinal pigment epithelium, choroidal thinning, undifferentiated nuclear layers of the retina, and a perivascular inflammatory infiltrate within the choroid. The optic nerve, present in 2 of the eyes, demonstrated atrophy. Expression of ZIKV antigen was present in the iris in cases 1, 3, and 4; the neural retina and choroid in case 1; and in the optic nerve in case 4.
Loss of retinal pigment epithelium, the presence of a thin choroid, a perivascular choroidal inflammatory infiltrate, and atrophic changes within the optic nerve were consistently present. These findings may be attributed to ZIKV infection and warrant further study
Human immunodeficiency virus continuum of care in 11 european union countries at the end of 2016 overall and by key population: Have we made progress?
Background. High uptake of antiretroviral treatment (ART) is essential to reduce human immunodeficiency virus (HIV) transmission and related mortality; however, gaps in care exist. We aimed to construct the continuum of HIV care (CoC) in 2016 in 11 European Union (EU) countries, overall and by key population and sex. To estimate progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 target, we compared 2016 to 2013 estimates for the same countries, representing 73% of the population in the region. Methods. A CoC with the following 4 stages was constructed: number of people living with HIV (PLHIV); proportion of PLHIV diagnosed; proportion of those diagnosed who ever initiated ART; and proportion of those ever treated who achieved viral suppression at their last visit. Results. We estimated that 87% of PLHIV were diagnosed; 92% of those diagnosed had ever initiated ART; and 91% of those ever on ART, or 73% of all PLHIV, were virally suppressed. Corresponding figures for men having sex with men were: 86%, 93%, 93%, 74%; for people who inject drugs: 94%, 88%, 85%, 70%; and for heterosexuals: 86%, 92%, 91%, 72%. The proportion suppressed of all PLHIV ranged from 59% to 86% across countries. Conclusions. The EU is close to the 90-90-90 target and achieved the UNAIDS target of 73% of all PLHIV virally suppressed, significant progress since 2013 when 60% of all PLHIV were virally suppressed. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control
