[Pseudohyperkalemia and thrombocytosis]. / Pseudo-hyperkaliémie et thrombocytose.

INTRODUCTION: Hyperkalemia is common in medicine and requires rapid management. Besides the easily evoked causes such as renal failure, adrenal insufficiency, cell lysis or iatrogenic causes, false or pseudo-hyperkalemia should not be forgotten. OBSERVATIONS: Three patients (1 man, 2 women, aged 78, 84, 88) were managed for thrombocytosis (between 1306 and 2404 G/L) and non-symptomatic hyperkalemia (between 6.1 and 7.7mmol/L) are reported. Kalemia on blood collected in heparin tube was normal (4.4-4.6mmol/L). Therefore, no specific treatment for this pseudohyperkalemia was required. CONCLUSION: The combination of thrombocytosis and non-symptomatic hyperkalemia should suggest the diagnosis of pseudohyperkalemia and should prompt for a control of kalemia on blood collected in heparin tube. The recognition of this diagnosis is important in order to avoid unnecessary and potentially deleterious treatment of hyperkalemia.

[Cerebral infarction and tuberculosis: case report and literature review]. / Infarctus cérébral et tuberculose : rapport d'un cas et analyse de la littérature.

INTRODUCTION: Although tuberculous meningitis is an uncommon presentation of tuberculosis, it still remains one of the deadliest forms of this disease. In this context, the occurrence of a cerebral infarct is an aggravating factor. OBSERVATION: A 48-year-old Asian man presented himself in the emergency room for dysarthria and dysphagia of progressive onset. Cerebral CT showed a recent ischemic defect of the right internal capsule. Lumbar puncture showed meningitis with low sugar levels. Pulmonary micronodules on the thoracic CT suggested tuberculosis, which was confirmed by a broncho-alveolar lavage. Anti-tuberculosis treatment and early corticosteroid resulted in an improvement of the patient's state. CONCLUSION: Cerebral infarctions in patients with tuberculous meningitis are events that cannot be underestimated in terms of frequency or severity. Their poor prognosis is partly the result of insufficiently defined management, which combines anti-tuberculosis treatment and early corticosteroid therapy.

[Nasopharyngeal carriage of SARS-CoV-2 among health personnel with symptoms suggestive of COVID-19 in a University Hospital in the Paris suburbs]. / Évaluation par RT-PCR du portage nasopharyngé du SARS-Cov-2 chez les personnels de santé symptomatiques suspects de COVID-19 dans un CHU de la banlieue parisienne.

INTRODUCTION: A consultation dedicated to symptomatic health professionals was opened at the beginning of the COVID-19 epidemic in order to meet the specific needs of this population. The objective of this work was to estimate the frequency of SARS-Cov-2 nasopharyngeal carriage in symptomatic healthcare workers suspected of having COVID-19 and to determine the factors associated with this carriage. METHODS: Of the 522 consultants, 308 worked in the Hospital and 214 outside. They had mild forms of COVID-19 and non-specific clinical signs with the exception of agueusia/anosmia, which was significantly more common in those with positive RT-PCR. The rate of RT-PCR positivity was 38% overall, without significant difference according to profession. It was higher among external consultants (47% versus 31%). In the hospital, this rate was significantly lower for symptomatic staff in the care sectors, compared to staff in the technical platforms and laboratories (24%, versus 45%, p = 0.006 and 54%, respectively, p < 0.001), but did not differ between staff in COVID units and other care sectors (30% versus 28%). Among the external consultants, the positivity rates of nursing home and private practices staff (53% and 55% respectively) were more than double that of acute care hospital staff (24%, p < 0.001). CONCLUSIONS: These data confirm the strong impact of COVID-19 on health professionals. The higher positivity rates among symptomatic professionals working outside the hospital compared to those working in hospital may be explained in part by a shortage of protective equipment and by difficulties in accessing virological diagnosis, which were greater outside the hospital when the epidemic began.

Prolonged suppressive antibiotic therapy for prosthetic joint infection in the elderly: a national multicentre cohort study.

During prosthetic joint infection (PJI), optimal surgical management with exchange of the device is sometimes impossible, especially in the elderly population. Thus, prolonged suppressive antibiotic therapy (PSAT) is the only option to prevent acute sepsis, but little is known about this strategy. We aimed to describe the characteristics, outcome and tolerance of PSAT in elderly patients with PJI. We performed a national cross-sectional cohort study of patients >75 years old and treated with PSAT for PJI. We evaluated the occurrence of events, which were defined as: (i) local or systemic progression of the infection (failure), (ii) death and (iii) discontinuation or switch of PSAT. A total of 136 patients were included, with a median age of 83 years [interquartile range (IQR) 81-88]. The predominant pathogen involved was Staphylococcus (62.1%) (Staphylococcus aureus in 41.7%). A single antimicrobial drug was prescribed in 96 cases (70.6%). There were 46 (33.8%) patients with an event: 25 (18%) with an adverse drug reaction leading to definitive discontinuation or switch of PSAT, 8 (5.9%) with progression of sepsis and 13 died (9.6%). Among patients under follow-up, the survival rate without an event at 2 years was 61% [95% confidence interval (CI): 51;74]. In the multivariate Cox analysis, patients with higher World Health Organization (WHO) score had an increased risk of an event [hazard ratio (HR) = 1.5, p = 0.014], whereas patients treated with beta-lactams are associated with less risk of events occurring (HR = 0.5, p = 0.048). In our cohort, PSAT could be an effective and safe option for PJI in the elderly.

HSV-2 meningoencephalitis in an immunocompetent young man: what is the pathogenesis and what is the treatment?

Herpes simplex encephalitis is rarely caused by herpes simplex virus type 2 (HSV-2) after the neonatal period. The pathogenesis of HSV-2 encephalitis is not known and its treatment has not been discussed. We report a case of mild meningoencephalitis secondary to HSV-2 primary infection after sexual risk behaviour in a healthy young man. The diagnosis was established upon clinical, biological and electroencephalographic criteria. Aciclovir treatment led to rapid clinical improvement. This case highlights HSV-2 as a rare cause of meningoencephalitis, and questions the management of this rare manifestation of HSV-2 infection.

The features of infectious diseases departments and anti-infective practices in France and Turkey: a cross-sectional study.

The aim of this study was to assess the infectious diseases (ID) wards of tertiary hospitals in France and Turkey for technical capacity, infection control, characteristics of patients, infections, infecting organisms, and therapeutic approaches. This cross-sectional study was carried out on a single day on one of the weekdays of June 17-21, 2013. Overall, 36 ID departments from Turkey (n = 21) and France (n = 15) were involved. On the study day, 273 patients were hospitalized in Turkish and 324 patients were followed in French ID departments. The numbers of patients and beds in the hospitals, and presence of an intensive care unit (ICU) room in the ID ward was not different in both France and Turkey. Bed occupancy in the ID ward, single rooms, and negative pressure rooms were significantly higher in France. The presence of a laboratory inside the ID ward was more common in Turkish ID wards. The configuration of infection control committees, and their qualifications and surveillance types were quite similar in both countries. Although differences existed based on epidemiology, the distribution of infections were uniform on both sides. In Turkey, anti-Gram-positive agents, carbapenems, and tigecycline, and in France, cephalosporins, penicillins, aminoglycosides, and metronidazole were more frequently preferred. Enteric Gram-negatives and hepatitis B and C were more frequent in Turkey, while human immunodeficiency virus (HIV) and streptococci were more common in France (p < 0.05 for all significances). Various differences and similarities existed in France and Turkey in the ID wards. However, the current scene is that ID are managed with high standards in both countries.

[Low vaccination coverage against influenza in elderly hospitalized in France]. / Faible taux de couverture vaccinale contre la grippe des sujets âgés hospitalisés en France.

PURPOSE: Annual influenza epidemics is still a major cause of illness and mortality especially in the elderly. Annual vaccination is the most effective way to prevent disease and reduce hospitalizations and deaths related to influenza in the elderly population. In France, there are few data available about vaccination coverage of elderly at risk for influenza. The aim of the study was to measure the influenza vaccination coverage and assess traceability in the elderly (≥ 75 years old) admitted to hospital. METHODS: In participating French hospitals, each patient aged 75 years or more, hospitalized in acute units of internal medicine, geriatric and infectious disease, was included in a multicentric point prevalence survey. RESULTS: Between April and May 2011, 63 departments of 28 hospitals participated and 903 patients were included (mean age of included patients: 85 years): 82% were previously living at home and 13% were institutionalized. Most of them had multiple diseases (77%) and 21% were admitted for a respiratory disease: 58% were vaccinated against influenza. A back-up for traceability was identified in 53% of cases. Patient refusal may be a common determinant of non-vaccination, as well as non-proposal by the attending physician. The vaccination rate did not differ according to usual living place including accommodation facilities in geriatric. CONCLUSION: Coverage for influenza vaccination is low in hospitalized elderly patients and traceability is insufficient. This vaccine, noncompliance mostly linked to the refusal of patients, is a worrisome public health problem, on which physicians and hospital staff in charge, as well as institutions, should turn attention toward a multi-professional preventive strategy against the morbidity risk of this infectious disease.

[Multidrug-resistant tuberculosis management in three French hospitals]. / Prise en charge de la tuberculose multirésistante dans trois hôpitaux français.

INTRODUCTION: Multidrug-resistant tuberculosis (MDR-TB) management is based on specific WHO guidelines. OBJECTIVES: The authors report MDR-TB management, in three French hospitals. METHOD: The authors retrospectively included patients with positive sample for multidrug-resistant Mycobacterium tuberculosis (isoniazid+rifampicin) from January 1, 2000 to December 31, 2005. The management was compared to the French and international prevalent guidelines. RESULTS: Sixteen patients were initially managed for MDR-TB by eight different medical teams over 6 successive years: 12 (75%) presented with primary MDR-TB. Management advice from the national referee center (NRC) for tuberculosis was reported in seven out of 14 treated cases. The median length of the intensive treatment was 2 months (IQR: 1-3). Eight patients (58%) had an overall treatment length of 18 months. The median number of effective drugs prescribed was 4 (IQR: 4-5). Nine patients (64%) were also managed in a sanatorium. Only eight patients (57%) completed the prescribed treatment. Nine patients were clinically cured and still followed-up, six of whom were bacteriologically cured. CONCLUSION: TB-MDR management was not conform to WHO guidelines in our study. Management in a sanatorium, NRC involvement, ambulatory DOT were highly beneficial.

[Cushing's syndrome induced by combined treatment with inhaled fluticasone and oral ritonavir]. / Syndrome de Cushing induit par la prise concomitante de fluticasone et de ritonavir.

INTRODUCTION: Fluticasone is a corticosteroid drug which is used in inhaled and nasal formulations for the treatment of asthma and allergic rhinitis. It is metabolized in the liver by the cytochrome P450. Ritonavir, an inhibitor of the HIV protease, also acts as an inhibitor of several isoenzymes of the P450 cytochrome. This property explains the many drug interactions observed with this agent. CASE REPORT: We report two cases of Cushing's syndrome with adrenal insufficiency associated with the combined administration of oral low dose ritonavir and moderate to high dose inhaled fluticasone. CONCLUSION: These observations highlight the fact that the combined administration of fluticasone and ritonavir must be avoided as well as the combined administration of fluticasone and other inhibitors of the cytochrome P450.
