A steadily increasing number of cases with neurological manifestations that are potentially related to COVID-19 are being reported in the literature. These most often include sudden anosmia, headache, encephalopathy, and stroke. The pathophysiological mechanisms underlying "Neuro-COVID" remain largely unknown, while the viral genome is very rarely detected in the cerebrospinal fluid. A study currently ongoing at the Cliniques universitaires Saint-Luc is aimed at investigating COVID-19 associated cerebrospinal fluid changes as well as immunohistochemical evidences of olfactory neuroepithelial cells direct viral infection and evidencing a direct infection of olfactory neuroepithelial cells.

Johann Morelle, Arnaud Devresse, Nathalie Demoulin, Valentine Gillion, Eric Goffin, Nada Kanaan, Laura Labriola, Michel Jadoul Published in the journal : May 2020 Category : Nephrology

This short contribution first focuses on the growing evidence showing that the kidney is a target for the coronavirus, with signs of kidney disease being a marker of COVID-19 severity. It next discusses the reasons not to withdraw angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in high-risk groups, as well as the potential risk of virus transmission inside the hemodialysis unit or via peritoneal dialysis. Finally, the article summarizes the data available regarding COVID-19 in kidney transplant recipients and concludes with some considerations concerning the major challenges faced when it comes to ensuring high-quality medical care during this pandemic.

COVID-19 in neonatology: a synthesis of the current situation

Julien Toulmonde, Olivier Danhaive, Nancy Laval, Fiammetta Piersigilli Published in the journal : May 2020 Category : Neonatology

The beginning of 2020 was marked by the spread of SARS-CoV-2 virus, a new virus from the beta-coronavirus family, from Hubei, China. This virus is responsible for a global pandemia of pneumonia with acute respiratory distress syndrome. Although the infection appears to be less acute in the pediatric population, neonates tend to be more frequently affected. Several cases of neonatal SARS-CoV-2 infections have been reported to date, including one in an extremely premature neonate. Nevertheless, the clinical picture seems to be less critical and neonatal mortality associated with COVID-19 has not been reported to date. The transmission mode from mother to infant has not been clearly demonstrated so far. Breastfeeding is allowed in most countries. The aim of this article is to summarize the epidemiological context and current knowledge on COVID-19 in infants and neonates.

The world is facing a serious pandemic. The disease called COVID-19 is caused by a new coronavirus, SARS-CoV-2, which started to spread in China in December 2019. COVID-19 is a condition that may be particularly serious and even fatal in elderly people, as well as in patients with comorbidities such as high blood pressure, cardiovascular diseases, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, and cancer. The clinical presentation is mild in approximately 80% of cases, moderate to severe in 15% of cases, and critical in 5% of cases. The most common symptoms of COVID-19 are fever, fatigue, muscle aches, and dry cough. Some patients may exhibit nasal congestion, chills, sore throat, or diarrhea. Severely ill patients can develop an acute respiratory distress syndrome (ARDS), shock, thrombosis, and multiple organ failure, and they are at risk of death. COVID-19 patients with ARDS have a poor prognosis, with an estimated mortality rate of more than 10%. SARS-CoV-2 is primarily transmitted through respiratory droplets. Airway and hand hygiene is therefore essential. The diagnosis is made by reverse transcription-polymerase chain reaction on a nasopharyngeal or oropharyngeal swab and, in suggestive cases, by chest computed tomography, which has a high sensitivity. There is currently no effective specific treatment for COVID-19. Many molecules have been tried or are under investigation. The treatment currently remains supportive.

COVID-19: A thrombotic disease?

Cédric Hermans, Catherine Lambert Published in the journal : May 2020 Category : Hémostase

COVID-19, especially in its severe form, is associated with a coagulopathy responsible for an increased incidence of venous and arterial thrombosis, pulmonary embolism, and pulmonary microthrombosis. Biologically, it results in increased D-dimer levels, which is of diagnostic and prognostic relevance. Depending on its severity, the COVID-19 infection requires a treatment with low-molecular-weight heparin (LMWH) at preventive or semi-therapeutic doses. In case of proven or strongly suspected thrombosis, anticoagulation with LMWH at therapeutic doses is recommended.

The SARS-CoV-2 pandemic poses an unprecedented challenge to the medical community. COVID-19 is potentially devastating for elderly patients, those who have comorbidities, as well as those with chronic hematological conditions.

Exceptional measures have been implemented by hospitals to prevent the spread of the virus and ensure optimal access to care for everyone, without jeopardizing the chances of recovery for patients with curable diseases. The hematological societies have issued guidelines that we summarize in this article for the diseases most commonly treated in our center, in the light of our experience.

COVID-19 in primary care medicine

Cassian Minguet Published in the journal : May 2020 Category : Médecine Générale

The COVID-19 pandemic has had and still has a remarkable impact on general medicine in Belgium. From the day the first Belgian case was diagnosed on February 4, 2020 until the beginning of de-containment- three full months have passed during which general medicine needed to re- structure itself more effectively to be able to speak up with one voice, adapted itself by switching to telemedicine during the population’s confinement period, and constantly developed updated management procedures. In the first month, general practitioners (GPs) did not expect a pandemic of this magnitude to occur. In the second month, things accelerated and GPs’ offices closed their doors, with GPs applying themselves the procedures they helped convey to their patients over the phone. By the third month, while suspicious cases sharply dropped, procedures needed to be strengthened. The situation is more difficult in nursing homes. Within 3 months, relations with patients, colleagues, paramedics, and institutions were, there, entirely altered. In other countries as well, there has been a profound change that is likely to profoundly impact medical practices in the long term. On the eve of a new phase consisting of progressive de-containment, general medicine is now properly prepared to assume its role of an essential player in the fight against coronavirus in the wider community.

A geriatric care unit dedicated to COVID-19 elderly patients

Isabelle Gilard, Isabelle De Brauwer, Pascale Cornette Published in the journal : May 2020 Category : Geriatry

This article describes the transformation of a geriatric care unit into a COVID-19 geriatric care unit. Besides ensuring proper treatment, the multidisciplinary team adapted its care practice and procedures with the objective of preserving the patients’ functional capacities. Each dimension of health is taken into account and the adaptations are described in the light of this challenge. Along with the severity of our patients' medical and functional situations, infectious isolation is the parameter that most influences the adaptations and generates the most complexity.

Ethical issues relevant to a pandemic crisis: A local planning strategy to manage the intensive care unit admissions to hospitals

Olivier Descamps, Pierre Henin, Pierre Hanotier, Francois-Xavier Lens, Jean-Paul Meurant, Michèle Pieterbourg, Sébastien Loix, Vanessa Wauters, Isabelle Reusen . Published in the journal : May 2020 Category : Ethics

The region of Mons-Borinage and Center in the Province of Hainaut was one of the most affected by the COVID-19 epidemic in both the Walloon region and Belgium. While facing the constant flow of patients and threat of intensive care unit saturation in this part of the Hainaut Province, the various medical teams that were particularly involved in the care of these patients (intensive care, emergency care, department of general internal medicine and geriatrics) had to implement admission management strategies in collaboration with general practitioners, medical directors, and the ethics committees.

COVID-19 and diabetes

Laura Orioli, Michel P. Hermans, Vanessa Preumont, Audrey Loumaye, Jean-Paul Thissen, Orsalia Alexopoulou, Raluca Furnica, Maria-Cristina Burlacu, Dominique Maiter, Jean-Cyr Yombi, Bernard Vandeleene Published in the journal : May 2020 Category : Diabétologie

Diabetes is one of the most commonly reported comorbidities in COVID-19-infected patients. According to current data, diabetic patients do not appear to be at increased risk of contracting SARS-CoV-2 compared to the general population. However, diabetes is a risk factor for developing severe and critical COVID-19 forms, which often require intensive care unit admission and, eventually, invasive mechanical ventilation, which are associated with high mortality rates. The characteristics of COVID-19 diabetic patients and prognostic impact of diabetes on SARS-CoV-2 infection are currently under investigation. Obesity, the main risk factor for incident Type 2 diabetes, appears to be more common in patients with critical COVID-19 forms that require mechanical invasive ventilation. In diabetic patients, COVID-19 is associated with poor glycemic control and acute metabolic complications like ketoacidosis. At present, there are no recommendations in favor of discontinuing antihypertensive medications that interact with the renin-angiotensin-aldosterone system. Owing to the risks of lactic acidosis and ketoacidosis, metformin and SGLT2 inhibitors should be discontinued in patients with severe COVID-19 forms. Finally, we advise a systematic screening for (pre)diabetes in patients with proven SARS-CoV-2 infection.
