RESUMO
Introduction: Coronavirus disease 2019 (COVID-19) poses an important risk of morbidity and of mortality, in patients after solid organ transplantation. Recommendations have been issued by various transplantation societies at the national and European level to manage the immunosuppressive (IS) regimen upon admission to intensive care unit (ICU). Method: The aim of this study was to evaluate the adequacy of IS regimen minimization strategy in kidney transplant recipients hospitalized in an ICU for severe COVID-19, in relation to the issued recommendations. Results: The immunosuppressive therapy was minimized in all patients, with respectively 63% and 59% of the patients meeting the local and european recommendations upon admission. During ICU stay, IS was further tapered leading to 85% (local) and 78% (european) adequacy, relative to the guidelines. The most frequent deviation was the lack of complete withdrawal of mycophenolic acid (22%). Nevertheless, the adequacy/inadequacy status was not associated to the ICU- or one-year-mortality. Discussion: In this single-center cohort, the only variable associated with a reduction in mortality was vaccination, emphasizing that the key issue is immunization prior to infection, not restoration of immunity during ICU stay.
RESUMO
BACKGROUND: Systematic treatment with intravenous acyclovir is usually given when varicella zoster virus (VZV) DNA is isolated in cerebrospinal fluid (CSF), indicating central nervous system (CNS) involvement. Our study aimed to describe therapeutic management and acute kidney injury (AKI) occurrence during acyclovir treatment of VZV infection with CNS involvement. METHODS: Multicentre, retrospective study including all patients from 2010 to 2022 with VZV DNA in CSF. Patient management and outcomes were compared according to clinical presentation and indications for intravenous acyclovir: i) definite (encephalitis, myelitis or stroke, peripheral nervous system (PNS) with ≥ 2 roots, herpes zoster ≥ 3 dermatomes, immunosuppression), ii) questionable (1 or 2 dermatomes) or iii) no indication (other situations). RESULTS: 154 patients were included (median age 66 (interquartile range 43-77), 87 (56%) males); 60 (39%) had encephalitis, myelitis or stroke, 35 (23%) had PNS involvement, 37 (24%) had isolated meningitis, 14 (9%) had isolated cutaneous presentation, and 8 (5%) had other presentations. Overall, 128 (83%) received intravenous acyclovir for more than 72 h. AKI occurred in 57 (37%) patients. Finally, 42 (27%) and 25 (16%) patients had respectively no or a questionable indication for intravenous acyclovir, while 29 (69%) and 23 (92%) of them received it for more than 72 h, with AKI in 13 (35%) and 13 (52%) patients, respectively. In-hospital mortality was 12% (n = 18), and no deaths were reported in isolated meningitis. CONCLUSIONS: Intravenous acyclovir is widely prescribed when VZV DNA is isolated in CSF, regardless of the clinical presentation, with a high rate of AKI. Further studies are needed to better define the value of intravenous acyclovir in isolated VZV meningitis.
RESUMO
A less than one-month-old infant with symptoms of rhinitis died unexpectedly in his sleep. He was not born prematurely and had no known underlying disease. Cerebrospinal fluid, nasopharyngeal and lung samples, and rectal swab were found to be positive for subgroup A rhinovirus, while the blood was negative. This case highlights the important finding that the rhinovirus, a common pathogen associated with upper respiratory tract infections, can sometimes, as the only pathogen, lead to complications such as a cerebrospinal infection and be involved in the sudden infant death syndrome (SIDS). Vigilance is necessary in case of viral infections in the infant's environment, and measures of hygiene and protection must be encouraged in order to reduce the risk of the SIDS.

Enterovirus D68 (EV-D68) infections are associated with severe respiratory disease and acute flaccid myelitis (AFM). The European Non-Polio Enterovirus Network (ENPEN) aimed to investigate the epidemiological and genetic characteristics of EV-D68 and its clinical impact during the fall-winter season of 2021/22. From 19 European countries, 58 institutes reported 10,481 (6.8%) EV-positive samples of which 1,004 (9.6%) were identified as EV-D68 (852 respiratory samples). Clinical data was reported for 969 cases. 78.9% of infections were reported in children (0-5 years); 37.9% of cases were hospitalised. Acute respiratory distress was commonly noted (93.1%) followed by fever (49.4%). Neurological problems were observed in 6.4% of cases with six reported with AFM. Phylodynamic/Nextstrain and phylogenetic analyses based on 694 sequences showed the emergence of two novel B3-derived lineages, with no regional clustering. In conclusion, we describe a large-scale EV-D68 European upsurge with severe clinical impact and the emergence of B3-derived lineages.
RESUMO
Our study aimed to compare children under 5 years hospitalized with respiratory syncytial virus in prepandemic and late-pandemic periods. We included 209 children at the Dijon University Hospital (France). We observed a nearly 3-fold increase in the number of cases in the late period, with older children, but less frequently requiring intensive care. These observations could help prepare a new pandemic.
