Successful high flow nasal cannula therapy for severe COVID-19 pneumonia is associated with tocilizumab use.

INTRODUCTION: Our aim was to determine the rate of success of HFNO and its relationship with current treatments for severe COVID-19. METHOD: This was a cohort study including patients admitted for HFNO because of respiratory failure despite oxygen therapy through a facial mask. Care was standardized, with systematic use of steroids and prevention or treatment of thromboembolic complications, and tocilizumab when deemed useful. HFNO failure was defined by the requirement for mechanical ventilation and/or death. RESULTS: In August 2021, among 1397 patients with COVID-19 admitted in the emergency department, 110 (7.8%) received HFNO (mean age 55 years, sex-ratio M/F 1.4). Thirteen patients (12%) had received a steroid treatment before hospital admission. At least one comorbid condition was observed in 57% of the patients. Mean duration of the disease at admission was 8.8 days and mean respiratory rate was 34/min. A CT scan was performed for 101 patients (92%), among whom 13 had a pulmonary embolism. All patients received a steroid treatment, and tocilizumab was prescribed in 79 cases (72%). Failure of HFNO was observed in 54 cases (49%); the only risk factor was the absence of tocilizumab administration: AOR [IC95%] 3.50 [1.40-8.69]. We observed a trend toward failure with steroid use before hospital admission: AOR 3.83 [0.96-16.66]. CONCLUSION: Success of HFNO, when all therapeutic means of treatment for severe COVID-19 pneumonia were applied, was associated with tocilizumab administration. Our data suggest the interest of a randomized study to determine whether HFNO is the right signal for prescription of anti-IL6 drugs.

Cotrimoxazole for community-acquired urinary tract infections leads to more adverse effects than fluoroquinolones.

BACKGROUND: For several years, we applied an internal guideline for community-acquired urinary tract infections (cUTI), targeting the reduction of fluoroquinolone use (FQ) and thereby favouring cotrimoxazole (CTM) prescription. Our aim was to report adverse effects (AE) and outcome for patients presenting with cUTI and treated with these compounds. METHODS: This cohort study was based on the dashboard of our department, bringing together 28 parameters for all patients, including diagnosis, microbiological data, antibiotic therapy, AE, length of hospital stay (LHS) and outcome. We included all patients with cUTI due to Enterobacteriaeae treated with CTM or FQ, and compared these 2 groups on in-hospital AE, LHS, and unfavourable outcome defined as intensive care requirement or death. RESULTS: From June 2008 to June 2019, 640 cUTI due to Enterobacteriaeae were observed, among which 295 (46%) treated with CTM and 345 (54%) with a FQ. There were 25 AE (3.9%): 17 (5.7%) in the CTM group, and 8 (2.3%) in the FQ group (P=0.025). Adverse effects were associated with increased LHS compared to patients without AE: 11±6 vs. 7±4 days respectively, P<0.001, 11.4±6.2 days in the CTM group vs. 9.2±5.8 in the FQ group (relative LHS increase of 73.5% and 29.5%, respectively). Unfavorable outcome occurred for 1 patient (0.3%) in the CTM group, and 5 (1.4%) in the FQ group, P=0.297. CONCLUSION: Favouring cotrimoxazole for cUTI due to Enterobacteriaceae was associated compared to FQ with more AE and prolonged LHS. A cost-effectiveness analysis to validate such therapeutic strategy is warranted.

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.

[Anti-TNF-α in the treatment of uveitis in the Besançon Hospital]. / Utilisation des anti-TNF-α dans les uvéites au CHU de Besançon.

BACKGROUND: Noninfectious chronic uveitis is a difficult-to-treat situation in which corticosteroids, immunosuppressive agents, and more recently, anti-tumor necrosis factor (TNF)-α are used to prevent and/or reverse severe visual impairment. This single-center retrospective study was designed to assess the use (indications, efficacy, and side effects) of anti-TNF-α agents in noninfectious uveitis. PATIENTS AND METHODS: Eight patients were analyzed: three children (age, 7-15 years) and five adults (age, 27-44 years). Anti-TNF-α agents were etanercept (three patients), adalimumab (four patients), and infliximab (four patients). Diagnoses were Behçet's diseases (n=3), sarcoidosis (n=1), juvenile chronic arthritis (n=2), spondyloarthropathy (n=2), one of the latter two combined with Crohn disease. In all cases, anti-TNF-α therapies were prescribed because uveitis and/or associated disease were not under control. RESULTS: Adalimumab and infliximab were effective for all patients. One patient with infliximab needed to add corticosteroids and immunosuppressive agents because of relapse. Etanercept was stopped in all cases due to a lack of effectiveness or a change in indication. In all patients, anti-TNF-α agents improved uveitis and the underlying systemic disease. In children, their use improved quality of life by corticosteroid weaning. Prescriptions did not comply with regulations for three children, because of age limits (etanercept, one; adalimumab, two). No adverse event was recorded. CONCLUSION: In this short case series, anti-TNF-α agents were effective both on uveitis and the underlying systemic disease and were well tolerated in patients with noninfectious chronic uveitis.

[Prostatic granulomas revealing a peripheral T-cell lymphoma]. / Granulomatose prostatique révélatrice d'un lymphome T périphérique.

INTRODUCTION: The presence of granulomas on tissue biopsie has been reported in a wide range of disorders. The clinical presentation and the diagnostic work-up of granulomatosis can be difficult as it is illustrated in the following report. CASE REPORT: A 59-year-old patient was referred in 2002 for a granulomatous prostatitis. Physical examination was normal. Except for the increase of prostate-specific antigen (which motivated a biopsy), the laboratory results were normal. Thoracic CT-scan disclosed mediastinal lymph nodes. A minor salivary gland biopsy was consistent with the diagnosis of sarcoidosis. In 2004, the patient presented an epidermal necrolysis, and in 2005 the deterioration of general status raised suspicion of a lymphoproliferative disorder. Liver and bone marrow biopsies revealed a granulomatous process. Despite steroid therapy, the patient died. Autopsy discloses a anaplasic T cell lymphoma. CONCLUSION: This report illustrates the relationship between sarcoidosis and lymphoma as a mode of presentation, a complication, or an accidental but misleading association? The association between anaplastic lymphoma and sarcoidosis is exceptional.

[Stiff person syndrome associated with thymoma. Efficacy of thymectomy]. / Syndrome de la personne raide associé à un thymome: efficacité de la thymectomie.

INTRODUCTION: Stiff person syndrome is a rare autoimmune neurologic disorder characterized by axial muscular rigidity and intermittent painful spasms. Three distinct forms are described: auto-immune, paraneoplastic and idiopathic. EXEGESIS: We report the case of a 51-year-old man with an history of Stiff Person Syndrome with typical clinical, electrophysiological and immunological findings. Anti-glutamic acid decarboxylase antibodies were present, as well as anti-amphiphysin antibodies, commonly reported in the paraneoplastic syndrome. CT scan revealed a thymoma. Surgical resection was followed by reduction of the neurologic symptoms, without lowering the auto antibodies titer. CONCLUSIONS: The association between Stiff Person Syndrome and thymoma is exceptional. Thymectomy is an effective treatment and may act without change of the autoantibodies titer. Patients with Stiff Person Syndrome should be systematically tested for thymoma.

[Pseudo-myasthenic myopathy in a woman with anorexia nervosa]. / Pseudomyasthénie grave chez une anorexique.

Skeletal myopathy, although foreseeable in severe malnutrition, has been rarely reported in patients with anorexia nervosa. We report a case of oculo-oropharyngeal myopathy mimicking myasthenia in a 42-year-old woman with an history of anorexia nervosa, completely reversible after refeeding with carbohydrate diet, mainly chocolate. Nutritional myopathies are not well known and therefore rarely looked for in patients with anorexia nervosa. Classical presentation is a myogenic syndrome with severe type 2 fibre atrophy and biochemical characteristics similar to Mac Ardle's disease. A clinical form mimicking myasthenia gravis has never been reported. Refeeding programme leads to total recovery within a few days.
