Clinical characteristics and outcomes of Respiratory Syncytial Virus-associated ARF in immunocompetent patients: a seven-year experience at a tertiary hospital in France

BACKGROUND

Respiratory syncytial virus (RSV) is widely recognized as a cause of acute respiratory failure in infants and immunocompromised patients. However, RSV can also contribute to acute respiratory failure in adults, particularly among the elderly population. The objective of this study was to analyze the clinical characteristics and outcomes of immunocompetent adults hospitalized for RSV infection.

METHODS

This retrospective study included all immunocompetent adult patients consecutively admitted to a tertiary care hospital with RSV-related acute respiratory failure over a seven-year period (2016 - 2023). Diagnosis of RSV infection was made through nasal swabs or pulmonary samples, with multiplex reverse transcription polymerase chain reaction (RT-PCR). Patients were eligible for inclusion if they required supplemental oxygen therapy for at least 48hours.

RESULTS

One hundred and four patients met the inclusion criteria. Median age [IQR] was 77 years [67 - 85]. Ninety-seven patients had at least one comorbidity (97/104, 93%). At the time of RSV diagnosis, 67 patients (67/104, 64%) experienced acute decompensation of a pre-existing chronic comorbidity. Antibiotics were started in 80% (77/104) of patients; however, only 16 patients had a confirmed diagnosis of bacterial superinfection. Twenty-six patients needed ventilatory support (26/104, 25%) and 21 were admitted to the intensive care unit (21/104, 20%). The median duration of oxygen therapy [IQR] was 6 days [3 - 9], while the median hospital length of stay [IQR] was 11 days [6 - 15]. The overall mortality rate within one month of hospital admission was 13% (14/104). The sole variables associated with one-month mortality were age and maximum oxygen flow during hospitalisation.

CONCLUSION

RSV-associated acute respiratory failure affected elderly individuals with multiple comorbidities and was associated with prolonged hospitalization and a high mortality rate.

Exclusive Oral Antibiotic Treatment for Hospitalized Community-Acquired Pneumonia: A Post-Hoc Analysis of a Randomized Clinical Trial

OBJECTIVES

In this study, we aimed to assess the efficacy of different ways of administration and types of beta-lactams for hospitalized community-acquired pneumonia (CAP).

METHODS

In this post-hoc analysis of a RCT on patients hospitalized for CAP (PTC trial) comparing 3-day versus 8-day durations of beta-lactams, which concluded to non-inferiority, we included patients who received either amoxicillin-clavulanate (AMC) or third-generation cephalosporin (3GC) regimens, and exclusively either intravenous or oral treatment for the first 3 days (followed by either 5 days of oral placebo or AMC according to randomization). Choice of route and molecule was left to the physician in charge. The main outcome was failure at 15 days after first antibiotic intake, defined as temperature>37.9°C, and/or absence of resolution/improvement of respiratory symptoms, and/or additional antibiotic treatment for any cause. The primary outcome according to route of administration was evaluated through logistic regression. Inverse probability treatment weighting (IPTW) with a propensity score model was used to adjust for non-randomization of treatment route and potential confounders. The difference in failure rates was also evaluated among several sub-populations (AMC versus 3GC treatments, or intravenous versus oral AMC, patients with multi-lobar infection, patients aged ≥ 65 years old, and patients with CURB65 scores of 3-4).

RESULTS

We included 200 patients from the original trial, with 93/200 (46.5%) patients only treated with intravenous treatment and 107/200 (53.5%) patients only treated with oral therapy. Failure rate at Day 15 was not significantly different among patients treated with initial intravenous versus oral treatment (25/93 (26.9%) versus 28/107 (26.2%), aOR 0.973 (95%CI 0.519-1.823), p=0.932). Failure rates at Day 15 were not significantly different among the subgroup populations.

CONCLUSIONS

Among hospitalized patients with CAP, there was no significant difference in efficacy between initial intravenous and exclusive oral treatment.

Long-term Oral Suppressive Antimicrobial Therapy in Infective Endocarditis (SATIE Study): An Observational Study

Background

The role of suppressive antimicrobial therapy (SAT) in infective endocarditis (IE) management has yet to be defined. The objective of this study was to describe the use of SAT in an IE referral center and the patients' outcomes.

Methods

We conducted a retrospective observational study in a French IE referral center (Paris). All patients with IE who received SAT between 2016 and 2022 were included.

Results

Forty-two patients were included (36 male [86%]; median age [interquartile range {IQR}], 73 [61-82] years). The median Charlson Comorbidity Index score (IQR) was 3 (1-4). Forty patients (95%) had an intracardiac device. The most frequent microorganisms were Enterococcus faecalis (15/42, 36%) and Staphylococcus aureus (12/42, 29%). SAT indications were absence of surgery despite clinical indication (28/42, 67%), incomplete removal of prosthetic material (6/42, 14%), uncontrolled infection source (4/42, 10%), persistent abnormal uptake on nuclear imaging (1/42, 2%), or a combination of the previous indications (3/42, 7%). Antimicrobials were mainly doxycycline (19/42, 45%) and amoxicillin (19/42, 45%). The median follow-up time (IQR) was 398 (194-663) days. Five patients (12%) experienced drug adverse events. Five patients (12%) presented with a second IE episode during follow-up, including 2 reinfections (different bacterial species) and 3 possible relapses (same bacterial species). Fourteen patients (33%) in our cohort died during follow-up. Overall, the 1-year survival rate was 84.3% (73.5%-96.7%), and the 1-year survival rate without recurrence was 74.1% (61.4%-89.4%).

Conclusions

SAT was mainly prescribed to patients with cardiac devices because of the absence of surgery despite clinical indication. Five (12%) breakthrough second IE episodes were reported. Prospective comparative studies are required to guide this empirical practice.

Enterococcal endocarditis management and relapses

Introduction

Enterococcus faecalis is the third micro-organism causing endocarditis and is associated with a significant relapse rate. The objective of this study was to describe the management of patients with Enterococcus faecalis endocarditis (EE) and its implication for relapses.

Methods

We conducted a monocentric, retrospective analysis of all patients hospitalized for EE including endocarditis or infection of cardiac implantable electronic device defined by the modified ESC 2015 Duke criteria in a referral centre in Paris, France.

Results

Between October 2016, and September 2022, 54 patients with EE were included, mostly men (n = 40, 74%) with a median age of 75 [68-80] years. A high risk for infective endocarditis (IE) was found in 42 patients (78%), including 14 (26%) previous histories of IE, and 32 (59%) histories of valvular cardiac surgery. The aortic valve was the most frequently affected (n = 36, 67%). Combination therapy was mainly amoxicillin-ceftriaxone during all the curative antibiotic therapy duration (n = 31, 57%). Surgery was indicated for 40 patients (74%), but only 27 (50%) were operated on, mainly due to their frailty. Among the 17 deaths (32%), six (11%) happened during the first hospitalization for EE. A suppressive antibiotic treatment was initiated in 15 (29%) patients, mostly because of not performing surgery. During the 6-year study period an EE relapse occurred in three (6%) patients.

Conclusions

EE is a worrying disease associated with a high risk of relapse and significant mortality. Suppressive antibiotic therapy could be a key treatment to limit the occurrence of relapses.

Predictive performance of surgical mortality risk scores in infective endocarditis

OBJECTIVES

This observational study aimed to evaluate Association pour l'Etude et la Prévention de l'Endocardite Infectieuse (AEPEI) surgery score predictive performance in comparison to general (EuroSCORE I, II) and specific (De Feo, PALSUSE) surgical risk scores for infective endocarditis (IE).

METHODS

The study included patients who underwent surgery for IE during the acute phase at Bichat University Hospital (Paris, France) between 1 January 2006 and 31 December 2016 and at Nancy University Hospital (Nancy, France) between 1 January 2009 and 31 December 2019. Patients with IE complicating percutaneous aortic valve implantations or implantable intra-cardiac devices were excluded. Discrimination and calibration were assessed using receiver operating characteristic curve analysis, calibration curves and the Hosmer-Lemeshow test.

RESULTS

In-hospital mortality rates were 18% at Bichat and 16% at Nancy. Discrimination was high for all risk scores at Bichat (area under the receiver operating characteristic curve = 0.77 for EuroSCORE I, 0.78 for EuroSCORE II, 0.76 for De Feo score, 0.72 for PALSUSE and 0.73 for AEPEI with 95% confidence interval ranging from 0.67 to 0.83), but lower at Nancy (0.56 for EuroSCORE I, 0.65 for EuroSCORE II, 0.63 for De Feo score, 0.67 for PALSUSE and 0.66 for AEPEI score with 95% confidence interval ranging from 0.47 to 0.75). With Brier score, all scores were adequately calibrated in both populations between 0.129 (De Feo) and 0.135 (PALSUSE) for Bichat and between 0.128 (De Feo) and 0.135 (EuroSCORE I) for Nancy. With the Hosmer-Lemeshow test, the AEPEI score exhibited the best calibration (observed/predicted ratio 1.058 in Bichat, 1.087 in Nancy).

CONCLUSIONS

This surgical score external validation in 2 large independent populations demonstrated that the AEPEI surgical score had the best predictive performance compared to other prognosis scores. It could be helpful in clinical practice to assist the endocarditis team in decision-making.

Absence of infective endocarditis relapse when end-of-treatment fluorodeoxyglucose positron emission tomography/computed tomography is negative

AIMS

In non-operated infective endocarditis (IE), relapse may impair the outcome of the disease. The aim of the study was to evaluate the relationship between end-of-treatment (EOT) fluorodeoxyglucose positron emission tomography/computed tomography FDG-PET/CT results and relapse in non-operated IE either on native or prosthetic valve.

METHODS AND RESULTS

We included 62 patients who underwent an EOT FDG-PET/CT for non-operated IE performed between 30 and 180 days of antibiotic therapy initiation. Qualitative valve assessment categorized initial and EOT FDG-PET/CT as negative or positive. Quantitative analyses were also conducted. Clinical data from medical charts were collected, including endocarditis team decision for IE diagnosis and relapse. Forty-one (66%) patients were male with a median age of 68 years (57; 80) and 42 (68%) had prosthetic valve IE. End-of-treatment FDG-PET/CT was negative in 29 and positive in 33 patients. The proportion of positive scans decreased significantly compared with initial FDG-PET/CT (53% vs. 77%, respectively, P < 0.0001). All relapses (n = 7, 11%) occurred in patients with a positive EOT FDG-PET/CT with a median delay after EOT FDG-PET/CT of 10 days (0; 45). The relapse rate was significantly lower in negative (0/29) than in positive (7/33) EOT FDG-PET/CT (P = 0.01).

CONCLUSION

In this series of 62 patients with non-operated IE who underwent EOT FDG-PET/CT, those with a negative scan (almost half of the study population) did not develop IE relapse after a median follow-up of 10 months. These findings need to be confirmed by prospective and larger studies.

Complicated scarring following mpox infection

We describe two patterns of complicated scarring following mpox lesions. The first was hypertrophic scarring of facial lesions in two patients and the second was a scarring folliculitis on peri-buccal lesions in two patients. The combination of deep dermic inflammation, local super-infection, and scratching may have led to these aesthetic complications.

Clinical characteristics of ambulatory and hospitalized patients with monkeypox virus infection: an observational cohort study

OBJECTIVES

A global outbreak of monkeypox virus infections in human beings has been described since April 2022. The objectives of this study were to describe the clinical characteristics and complications of patients with a monkeypox infection.

METHODS

All consecutive patients with a polymerase chain reaction (PCR)-confirmed monkeypox infection seen in a French referral centre were included.

RESULTS

Between 21 May and 5 July 2022, 264 patients had a PCR-confirmed monkeypox infection. Among them, 262 (262/264, 99%) were men, 245 (245/259, 95%) were men who have sex with men, and 90 (90/216, 42%) practiced chemsex in the last 3 months. Seventy-three (73/256, 29%) patients were living with human immunodeficiency virus infection, and 120 (120/169, 71%) patients were taking pre-exposure prophylaxis against human immunodeficiency virus infection. Overall, 112 (112/236, 47%) patients had contact with a confirmed monkeypox case; it was of sexual nature for 95% of the contacts (86/91). Monkeypox virus PCR was positive on the skin in 252 patients, on the oropharyngeal sample in 150 patients, and on blood in eight patients. The majority of patients presented with fever (171/253, 68%) and adenopathy (174/251, 69%). Skin lesions mostly affected the genital (135/252, 54%) and perianal (100/251, 40%) areas. Overall, 17 (17/264, 6%) patients were hospitalized; none of them were immunocompromised. Complications requiring hospitalization included cellulitis (n = 4), paronychia (n = 3), severe anal and digestive involvement (n = 4), non-cardia angina with dysphagia (n = 4), blepharitis (n = 1), and keratitis (n = 1). Surgical management was required in four patients.

CONCLUSION

The current outbreak of monkeypox infections has specific characteristics: it occurs in the men who have sex with men community; known contact is mostly sexual; perineal and anal areas are frequently affected; and severe complications include superinfected skin lesions, paronychia, cellulitis, anal and digestive involvement, angina with dysphagia, and ocular involvement.

Real-life temocillin use in Greater Paris area, effectiveness and risk factors for failure in infections caused by ESBL-producing Enterobacterales: a multicentre retrospective study

Background

Temocillin is a β-lactam that is not hydrolysed by ESBLs.

Objectives

To describe the real-life use of temocillin, to assess its effectiveness in infections caused by ESBL-producing Enterobacterales, and to identify risk factors for treatment failure.

Methods

Retrospective multicentric study in eight tertiary care hospitals in the Greater Paris area, including patients who received at least one dose of temocillin for ESBL infections from 1 January to 31 December 2018. Failure was a composite criterion defined within 28 day follow-up by persistence or reappearance of signs of infection, and/or switch to suppressive antibiotic treatment and/or death from infection. A logistic regression with univariable and multivariable analysis was performed to identify risks associated with failure.

Results

Data on 130 infection episodes were collected; 113 were due to ESBL-producing Enterobacterales. Mean age was 65.2 ± 15.7 years and 68.1% patients were male. Indications were mostly urinary tract infections (UTIs) (85.8%), bloodstream infections (11.5%), respiratory tract infections (RTIs) (3.5%) and intra-abdominal infections (3.5%). Bacteria involved were Escherichia coli (49.6%), Klebsiella pneumoniae (44.2%) and Enterobacter cloacae (8.8%). Polymicrobial infections occurred in 23.0% of cases. Temocillin was mostly used in monotherapy (102/113, 90.3%). Failure was found in 13.3% of cases. Risk factors for failure in multivariable analysis were: RTI (aOR 23.3, 95% CI 1.5-358.2) and neurological disease (aOR 5.3, 95% CI 1.5-18.6).

Conclusions

The main use of temocillin was UTI due to ESBL-producing E. coli and K. pneumoniae, with a favourable clinical outcome. The main risk factor for failure was neurological disease.

Réactivation de tuberculose après traitement immunomodulateur pour une infection sévère à SARS-CoV-2

Nous rapportons deux cas de réactivation tuberculeuse après COVID-19 sous corticostéroïdes et tocilizumab. Ils ont présenté une lymphopénie, des signes cliniques limités, des signes radiologiques inhabituels mais des prélèvements microbiologiques positifs. Le dépistage de l'infection tuberculeuse latente (ITL) étant inapproprié dans ce contexte, il faudrait discuter de la traiter systématiquement chez des patients les plus à risque en cas de traitement immunomodulateur.

Contribution of Clinical Metagenomics to the Diagnosis of Bone and Joint Infections

Bone and joint infections (BJIs) are complex infections that require precise microbiological documentation to optimize antibiotic therapy. Currently, diagnosis is based on microbiological culture, sometimes complemented by amplification and sequencing of the 16S rDNA gene. Clinical metagenomics (CMg), that is, the sequencing of the entire nucleic acids in a sample, was previously shown to identify bacteria not detected by conventional methods, but its actual contribution to the diagnosis remains to be assessed, especially with regard to 16S rDNA sequencing. In the present study, we tested the performance of CMg in 34 patients (94 samples) with suspected BJIs, as compared to culture and 16S rDNA sequencing. A total of 94 samples from 34 patients with suspicion of BJIs, recruited from two sites, were analyzed by (i) conventional culture, (ii) 16S rDNA sequencing (Sanger method), and (iii) CMg (Illumina Technology). Two negative controls were also sequenced by CMg for contamination assessment. Based on the sequencing results of negative controls, 414 out of 539 (76.7%) bacterial species detected by CMg were considered as contaminants and 125 (23.2%) as truly present. For monomicrobial infections (13 patients), the sensitivity of CMg was 83.3% as compared to culture, and 100% as compared to 16S rDNA. For polymicrobial infections (13 patients), the sensitivity of CMg was 50% compared to culture, and 100% compared to 16S rDNA. For samples negative in culture (8 patients, 21 samples), CMg detected 11 bacteria in 10 samples from 5 different patients. In 5/34 patients, CMg brought a microbiological diagnosis where conventional methods failed, and in 16/34 patients, CMg provided additional information. Finally, 99 antibiotic resistance genes were detected in 24 patients (56 samples). Provided sufficient genome coverage (87.5%), a correct inference of antibiotic susceptibility was achieved in 8/8 bacteria (100%). In conclusion, our study demonstrated that the CMg provides complementary and potentially valuable data to conventional methods of BJIs diagnosis.

Pulmonary bacterial infections in adult patients hospitalized for COVID-19 in standard wards

OBJECTIVES

During the COVID-19 pandemic, antibiotic use was very common. However, bacterial co-/secondary infections with coronaviruses remain largely unknown in standard wards. We aimed to investigate the characteristics of pulmonary bacterial infections associated with COVID-19 in hospitalized patients.

METHODS

A retrospective monocentric observational study was conducted in Bichat hospital, France, between February 26 and April 22, 2020. All patients hospitalized in standard wards with COVID-19 (positive nasopharyngeal PCR and/or typical aspect on CT scan) and diagnosed with pulmonary bacterial infection (positive bacteriological samples) were included. Bacteriological and clinical data were collected from the microbiology laboratories and patient's medical records.

RESULTS

Twenty-three bacteriological samples from 22 patients were positive out of 2,075 screened samples (1.1%) from 784 patients (2.8%). Bacterial infection occurred within a median of 10 days after COVID-19 onset. Diagnosis of pulmonary bacterial infection was suspected on increase of oxygen requirements (20/22), productive cough or modification of sputum aspect (17/22), or fever (10/22). Positive samples included 13 sputum cultures, one FilmArray® assay on sputum samples, one bronchoalveolar lavage, six blood cultures, and two pneumococcal urinary antigen tests. The most frequent bacteria were Pseudomonas aeruginosa (6/23), Staphylococcus aureus (5/23), Streptococcus pneumoniae (4/23), Enterococcus faecalis (3/23), and Klebsiella aerogenes (3/23). No Legionella urinary antigen test was positive. Four out of 496 nasopharyngeal PCR tests (0.8%) were positive for intracellular bacteria (two Bordetella pertussis and two Mycoplasma pneumonia).

CONCLUSIONS

Pulmonary bacterial secondary infections and co-infections with SARS-CoV-2 are uncommon. Antibiotic use should remain limited in the management of COVID-19.

Factors Associated With Treatment Failure in Moderately Severe Community-Acquired Pneumonia: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

Failure of treatment is the most serious complication in community-acquired pneumonia (CAP).

OBJECTIVE

To assess the potential risk factors for treatment failure in clinically stable patients with CAP.

DESIGN, SETTING, AND PARTICIPANTS

This secondary analysis assesses data from a randomized clinical trial on CAP (Pneumonia Short Treatment [PTC] trial) conducted from December 19, 2013, to February 1, 2018. Data analysis was performed from July 18, 2019, to February 15, 2020. Patients hospitalized at 1 of 16 centers in France for moderately severe CAP who were clinically stable at day 3 of antibiotic treatment were included in the PTC trial and analyzed in the per-protocol trial population.

INTERVENTIONS

Patients were randomly assigned (1:1) on day 3 of antibiotic treatment to receive β-lactam (amoxicillin-clavulanate [1 g/125 mg] 3 times daily) or placebo for 5 extra days.

MAIN OUTCOMES AND MEASURES

The main outcome was failure at 15 days after first antibiotic intake, defined as a temperature greater than 37.9 °C and/or absence of resolution or improvement of respiratory symptoms and/or additional antibiotic treatment for any cause. The association among demographic characteristics, baseline clinical and biological variables available (ie, at the first day of β-lactam treatment), and treatment failure at day 15 among the per-protocol trial population was assessed by univariate and multivariable logistic regressions.

RESULTS

Overall, 310 patients were included in the study; this secondary analysis comprised 291 patients (174 [59.8%] male; mean [SD] age, 69.6 [18.5] years). The failure rate was 26.8%. Male sex (odds ratio [OR], 1.74; 95% CI, 1.01-3.07), age per year (OR, 1.03; 95% CI, 1.01-1.05), Pneumonia Severe Index score (OR, 1.01; 95% CI, 1.00-1.02), the presence of chronic lung disease (OR, 1.85; 95% CI, 1.03-3.30), and creatinine clearance (OR, 0.99; 95% CI, 0.98-1.00) were significantly associated with failure in the univariate analysis. When the Pneumonia Severe Index score was excluded to avoid collinearity with age and sex in the regression model, only male sex (OR, 1.92; 95% CI, 1.08-3.49) and age (OR, 1.02; 95% CI, 1.00-1.05) were associated with failure in the multivariable analysis.

CONCLUSIONS AND RELEVANCE

In this secondary analysis of a randomized clinical trial, among patients with CAP who reached clinical stability after 3 days of antibiotic treatment, only male sex and age were associated with higher risk of failure, independent of antibiotic treatment duration and biomarker levels. Another randomized clinical trial is needed to evaluate the impact of treatment duration in populations at higher risk for treatment failure.

Sociodemographic characteristics and transmission risk factors in patients hospitalized for COVID-19 before and during the lockdown in France

Background

The efficacy of lockdown in containing the COVID-19 pandemic has been reported in different studies. However, the impact on sociodemographic characteristics of individuals infected with SARS-CoV-2 has not been evaluated. The aim of this study was to describe the changes in sociodemographic characteristics of patients hospitalized for COVID-19 and to compare the transmission risk factors of COVID-19 before and during lockdown in France.

Methods

An observational retrospective study was conducted in a University Hospital in Paris, France. Data from patients hospitalized for COVID-19 in the Infectious Diseases Department between February 26 and May 11, 2020 were collected. The study population was divided into 2 groups: group A of patients infected before lockdown, and group B of patients infected during lockdown, considering a maximum incubation period of 14 days. Sociodemographic characteristics and transmission risk factors were compared between the 2 groups using Student’s t-test for continuous variables and Chi-2 test or Fisher exact test for categorical variables.

Results

Three hundred eighty-three patients were included in the study, 305 (79.6%) in group A and 78 (20.4%) in group B. Patients in group A were significantly younger (60.0 versus (vs) 66.5 years (p = 0.03)). The professionally active population was larger in group A (44.3% vs 24.4%). There were significantly more non-French-speaking people in group B (16.7% vs 6.6%, p <  0.01). Most patients from group A had individual accommodation (92.8% vs 74.4%, p <  0.01). Contact with a relative was the main transmission risk factor in both groups (24.6% vs 33.3%, p = 0.16). Recent travel and large gathering were found only in group A. The proportion of people living in disadvantaged conditions, such as homeless people or people living in social housing, was significantly higher in group B (11.5% vs 4.3%, p = 0.03) as was the proportion of institutionalized individuals (14.1% vs 3.0%, p <  0.01).

Conclusions

In this study conducted in patients hospitalized for COVID-19 in Paris, France, the likelihood of being infected despite the lockdown was higher for people who do not speak French, live in social housing, are homeless or institutionalized. Targeted measures have to be implemented to protect these populations.

Impact of a medication reconciliation care bundle at hospital discharge on continuity of care: A randomised controlled trial

OBJECTIVE

To compare the impact of a care bundle including medication reconciliation at discharge by a pharmacist versus standard of care, on continuity of therapeutic changes between hospital and primary care and outcome of patients, within 1 month after discharge.

METHODS

Randomised controlled trial in 120 adult patients with at least one chronic disease and three current medications before admission, hospitalised in an infectious disease department of a tertiary hospital and discharged home. Patients were randomly assigned (1:1) to receive a discharge care bundle including medication reconciliation, counselling session and documentation transfer to primary care physician (PCP) (intervention group) or standard of care (control group). Primary outcome was the proportion of in-hospital prescription changes, not maintained by the PCP, 1 month after discharge. Secondary outcome measures included the proportion of patients experiencing early PCP's consultation, hospital readmissions or adverse reactions within 1-month postdischarge and cost of discharge prescriptions.

RESULTS

Baseline characteristics were comparable between the two groups. One month after discharge, the proportion of in-hospital prescription changes, not maintained by the PCP, was 11% in the intervention group versus 24% in the control group (P = .007). The median delay before PCP's consultation was longer in the intervention group (30.5 vs 19.5 days, P = .013), there were fewer patients readmitted to hospital (3.4% vs 20.7%, P = .009, odds ratio (OR) = 0.13 [0.02-0.53]) and fewer patients who suffered from adverse drug reaction (7.0% vs 22.8%, P = .04, OR = 0.26 [0.07-0.78]).

CONCLUSION

This care bundle resulted in the reduction of treatment changes between hospital discharge and primary care.

Endocarditis caused by Thalassospira sp

We report a case of an infective endocarditis caused by a Thalassospira sp. in a 53-year-old man with pre-existing valvular lesions and living in French Polynesia as a fisherman. The strain was identified with DNA-sequecing methods while it was not by mass spectrometry.

Chronic use of renin-angiotensin-aldosterone system blockers and mortality in COVID-19: A multicenter prospective cohort and literature review

Aims

The role of renin‐angiotensin‐aldosterone system (RAAS) blockers on the course of coronavirus disease 2019 (COVID‐19) is debated. We assessed the association between chronic use of RAAS blockers and mortality among inpatients with COVID‐19 and explored reasons for discrepancies in the literature.

Methods and results

We included adult hypertensive patients from a prospective nationwide cohort of 3512 inpatients with COVID‐19 up to June 30, 2020. Cox proportional hazard models with various adjustment or propensity weighting methods were used to estimate the hazard ratios (HR) of 30‐day mortality for chronic users versus non‐users of RAAS blockers. We analyzed data of 1160 hypertensive patients: 719 (62%) were male and 777 (67%) were older than 65 years. The main comorbidities were diabetes (n = 416, 36%), chronic cardiac disease (n = 401, 35%), and obesity (n = 340, 29%); 705 (61%) received oxygen therapy. We recorded 135 (11.6%) deaths within 30 days of diagnosis. We found no association between chronic use of RAAS blockers and mortality (unadjusted HR = 1.13, 95% CI [0.8–1.6]; propensity inverse probability treatment weighted HR = 1.09 [0.86‐1.39]; propensity standardized mortality ratio weighted HR = 1.08 [0.79–1.47]). Our comprehensive review of previous studies highlighted that significant associations were mostly found in unrestricted populations with inappropriate adjustment, or with biased in‐hospital exposure measurement.

Conclusion

Our results do not support previous concerns regarding these drugs, nor a potential protective effect as reported in previous poorly designed studies and meta‐analyses. RAAS blockers should not be discontinued during the pandemic, while in‐hospital management of these drugs will be clarified by randomized trials. NCT04262921.

Cytomegalovirus proctitis as a complication of COVID-19 with immunosuppressive treatments

We report a case of reactivated biopsy-proven cytomegalovirus proctitis complicating the course of severe COVID-19 pneumonia treated with dexamethasone, anakinra and lopinavir/ritonavir. No other contributing factor was found than iatrogenic immunosuppression and COVID-19 immune dysregulation. We draw attention to the immunosuppressive risk when treating severe COVID-19 pneumonia with immunomodulators.

Discontinuing β-lactam treatment after 3 days for patients with community-acquired pneumonia in non-critical care wards (PTC): a double-blind, randomised, placebo-controlled, non-inferiority trial

BACKGROUND

Shortening the duration of antibiotic therapy for patients admitted to hospital with community-acquired pneumonia should help reduce antibiotic consumption and thus bacterial resistance, adverse events, and related costs. We aimed to assess the need for an additional 5-day course of β-lactam therapy among patients with community-acquired pneumonia who were stable after 3 days of treatment.

METHODS

We did this double-blind, randomised, placebo-controlled, non-inferiority trial (the Pneumonia Short Treatment [PTC]) in 16 centres in France. Adult patients (aged ≥18 years) admitted to hospital with moderately severe community-acquired pneumonia (defined as patients admitted to a non-critical care unit) and who met prespecified clinical stability criteria after 3 days of treatment with β-lactam therapy were randomly assigned (1:1) to receive β-lactam therapy (oral amoxicillin 1 g plus clavulanate 125 mg three times a day) or matched placebo for 5 extra days. Randomisation was done using a web-based system with permuted blocks with random sizes and stratified by randomisation site and Pneumonia Severity Index score. Participants, clinicians, and study staff were masked to treatment allocation. The primary outcome was cure 15 days after first antibiotic intake, defined by apyrexia (temperature ≤37·8°C), resolution or improvement of respiratory symptoms, and no additional antibiotic treatment for any cause. A non-inferiority margin of 10 percentage points was chosen. The primary outcome was assessed in all patients who were randomly assigned and received any treatment (intention-to-treat [ITT] population) and in all patients who received their assigned treatment (per-protocol population). Safety was assessed in the ITT population. This study is registered with ClinicalTrials.gov, NCT01963442, and is now complete.

FINDINGS

Between Dec 19, 2013, and Feb 1, 2018, 706 patients were assessed for eligibility, and after 3 days of β-lactam treatment, 310 eligible patients were randomly assigned to receive either placebo (n=157) or β-lactam treatment (n=153). Seven patients withdrew consent before taking any study drug, five in the placebo group and two in the β-lactam group. In the ITT population, median age was 73·0 years (IQR 57·0-84·0) and 123 (41%) of 303 participants were female. In the ITT analysis, cure at day 15 occurred in 117 (77%) of 152 participants in the placebo group and 102 (68%) of 151 participants in the β-lactam group (between-group difference of 9·42%, 95% CI -0·38 to 20·04), indicating non-inferiority. In the per-protocol analysis, 113 (78%) of 145 participants in the placebo treatment group and 100 (68%) of 146 participants in the β-lactam treatment group were cured at day 15 (difference of 9·44% [95% CI -0·15 to 20·34]), indicating non-inferiority. Incidence of adverse events was similar between the treatment groups (22 [14%] of 152 in the placebo group and 29 [19%] of 151 in the β-lactam group). The most common adverse events were digestive disorders, reported in 17 (11%) of 152 patients in the placebo group and 28 (19%) of 151 patients in the β-lactam group. By day 30, three (2%) patients had died in the placebo group (one due to bacteraemia due to Staphylococcus aureus, one due to cardiogenic shock after acute pulmonary oedema, and one due to heart failure associated with acute renal failure) and two (1%) in the β-lactam group (due to pneumonia recurrence and possible acute pulmonary oedema).

INTERPRETATION

Among patients admitted to hospital with community-acquired pneumonia who met clinical stability criteria, discontinuing β-lactam treatment after 3 days was non-inferior to 8 days of treatment. These findings could allow substantial reduction of antibiotic consumption.

Co-infection et surinfection bactérienne chez les patients hospitalisés pour COVID-19: une étude rétrospective monocentrique

Introduction

Durant la pandémie de COVID-19, la prescription d’antibiotique a été importante. Cependant, les surinfections et co-infections bactériennes associées aux coronavirus sont peu décrites, et concernent principalement les patients de soins intensifs.

Matériels et méthodes

Une étude observationnelle rétrospective monocentrique a été menée dans notre CHU du 26/02/2020 au 22/04/2020. Ont été inclus tous les patients hospitalisés pour une COVID-19 (PCR respiratoire positive à SARS-CoV-2 ou atteinte scannographique compatible) hors service de réanimation et présentant une infection bactérienne documentée par un prélèvement bactériologique positif parmi: prélèvement respiratoire (ECBC, aspiration bronchique, LBA), hémoculture, antigénurie légionnelle ou pneumocoque, ou PCR nasopharyngée (Bordetella pertussis, Mycoplasma pneumoniae et légionnelle). Les données bactériologiques ont été obtenues par les laboratoires de bactériologie et virologie et les données cliniques recueillies à partir du dossier médical des patients.

Résultats

Au total, 2710 prélèvements ont été réalisés chez 778 patients hospitalisés: 957 hémocultures, 169 ECBC, 3 aspirations bronchiques, 2 LBA, 537 PCR nasopharyngées, 517 antigénuries légionnelle et 525 antigénuries pneumocoque. Quarante et un prélèvements étaient positifs (1,5 %) dont quatorze ont été considérés comme une colonisation par les cliniciens. Vingt neuf prélèvements positifs (1,1 %) ont été considérés comme pathogènes chez 27 patients (3,5 %): 15 ECBC, 2 aspirations bronchiques, 1 LBA, 7 hémocultures, 2 antigénuries et 4 PCR nasopharyngées. Parmi les 27 patients, 18 (66,7 %) avaient des comorbidités dont 10 (37 %) une pathologie respiratoire chronique. Huit patients (29,6 %) étaient sous traitement immunosuppresseur au long cours et 15 (55,6 %) ont reçu des corticoïdes ou autres traitements immunomodulateurs pour la COVID-19. Le delais entre l’apparition des symptômes de COVID-19 et la survenue de la surinfection bactérienne était en moyenne de 11 jours. Les arguments en faveur d’une surinfection étaient l’augmentation des besoins en oxygène (n = 22, 81,5 %), la toux expectorante (n= 20, 74,0 %) ou la modification de la toux (n = 5, 18,5 %) et la présence de fièvre (n= 5, 18,5 %). Un patient avait un tableau de sepsis. Les pathogènes les plus fréquemment retrouvés nétaient: Pseudomonas aeruginosa (n = 8, 29,6 %), Staphylococcus aureus (n = 5, 18,5 %), Streptococcus pneumoniae (n = 4, 14,8 %) et Enterococcus faecalis (n = 3, 11,1 %). Quatre patients (0,5 %) avaient une co-infection à bactérie intracellulaire: 2 à Bordetella pertussis et 2 à Mycoplasma pneumoniae. Aucune antigénurie légionnelle n’est revenue positive.

Conclusion

Le taux de surinfections et de co-infections bactériennes dans la COVID-19 semble faible. Ce faible taux est en faveur d’une utilisation limitée des antibiotiques dans la prise en charge de la COVID-19.

Quelles sont les conséquences de l’épidémie COVID-19 sur l’organisation des soins ?

Introduction

Le 30/01/2020, l’OMS déclare une urgence de Santé Publique de portée internationale suite à l’épidémie de COVID-19. Les conséquences des épidémies sont nombreuses, aussi bien pour les patients que pour l’ensemble du système de santé. Cette étude a pour but d’évaluer les conséquences de l’épidémie COVID-19 sur l’organisation des soins à l’échelle hospitalière.

Matériels et méthodes

Nous avons récolté des données sur la réponse épidémique dans un hôpital prenant en charge des patients infectés par le SARS-CoV-2 à l’aide de plusieurs sources : entretiens individuels semi-structurés, périodes d’observation ethnographique in situ et analyse documentaire. Les entretiens ont été réalisés auprès des différents professionnels de l’hôpital. Les différents points de vue et niveaux organisationnels ont été envisagés lors des entretiens à l’aide d’une approche adaptative et itérative. Les entretiens étaient enregistrés, transcrits et codés à l’aide du logiciel NVivo 12. Les données qualitatives ont été analysées par une analyse thématique inductive.

Résultats

Nous avons réalisé 37 entretiens avec des personnels de santé (infirmier/e/s, médecins, aides-soignant/e/s, manipulateurs radiologiques, cadres de santé) dans plusieurs services (urgences, maladies infectieuses, réanimation, chirurgie cardiaque, équipe d’hygiène) et avec des personnels administratifs (personnel de sécurité, de logistique, de communication et de direction). Nous avons également collecté plus de 100 heures d’observation ethnographique. Concernant la réponse à l’épidémie, nous avons identifié des éléments facilitateurs comme la gestion de cas suspects pour les épidémies antérieures (MERS-CoV et Ebola), la réalisation d’exercices réguliers par l’équipe d’hygiène, et l’existence préalable de protocoles mais aussi des problèmes non anticipés comme la gestion des déchets à risques biologiques, des difficultés à recruter des infirmiers intérimaires ou la pression médiatique et les rumeurs. Les conséquences de l’épidémie ont été directes ; réorganisation du service de maladies infectieuses, de réanimation médicale et de virologie mais également indirectes ; diminution de l’activité de l’équipe mobile d’infectiologie et des activités d’enseignement, inquiétude des patients non concernés et annulation de rendez-vous. Ont été soulignés par les participants l’importance de maintenir la cohésion des équipes entre personnels travaillant auprès de patients infectés par le SARS-CoV-2 et personnels non impliqués, d’intégrer de façon harmonieuse la recherche clinique dans la prise en charge médicale et de réaliser un travail de veille bibliographique en temps réel afin d’actualiser la prise en charge des cas possibles et confirmés.

Conclusion

L’épidémie COVID-19 a eu de nombreuses conséquences sur l’organisation aussi bien des services médicaux concernés que des services non directement impliqués et des services administratifs. Cette étude permet d’identifier des pistes d’amélioration pour la réponse épidémique.

COVIDOM : une expérience de télémédecine unique pour la gestion du COVID-19

Introduction

Afin d’éviter l’engorgement du système de soin et de soulager les praticiens ainsi que d’éviter les contaminations hospitalières, le dispositif de télésuivi COVIDOM a été mis en place en urgence à l’échelle de l’Ile de France. Il permet le suivi des patients à domicile atteint du COVID-19. Il s’agit d’une initiative réalisée en partenariat entre l’AP-HP (Assistance des Hôpitaux de Paris), l’ARS (Agence régionale de Santé) et l’URPS (Union régionale des professionnels de santé) Ile-de-France. Nous présentons ce dispositif.

Matériels et méthodes

Description et évaluation du dispositif COVIDOM déployé en Ile-de-France.

Résultats

COVIDOM est un dispositif de télésuivi reposant sur des questionnaires renseignés par le patient, atteint de COVID, 1 ou 2 fois par jour ; 7 items étaient renseignés (fréquence cardiaque, dyspnée, fréquence respiratoire, température, malaise, frissons, difficulté au confinement) et généraient des alertes vertes, oranges ou rouges en fonction des seuils définis. Les alertes étaient traitées par un plateau de télésurveillance supervisé par des médecins représentant au total plus de 2 000 personnes sur l’ensemble de la période. Les patients pouvaient être inclus en consultation (de ville ou hospitalière), en sortie d’hospitalisation ou par la régulation du SAMU et étaient suivi 30j au total. Finalement du 9 mars au 8 juin 2020, 70 914 patients ont été inclus par 10 000 médecins, l’âge médian des patients était de 43 ans avec un sexe ratio de 0,71. Au total 266 619 alertes ont été générés dont 22 958 alertes rouges et 243 661 oranges. Au pic de l’épidémie, jusqu’à 10.000 alertes/jour ont été prises en charge par 40 « cellules » de télésurveillance, soit 200 postes de travail 7j/7 de 8 h à 20 h. La capacité de suivi était d’environ 1.200 patients par cellule. Sur le plateau 1.100 intervenants de télésurveillance (ITS) ont été formés : externes médecine/dentaires, professionnels de santé (kiné, pharmaciens, IDE, dentistes, cadres de santé), plus de 990 médecins référents (salariés AP-HP, libéraux, retraités) et enfin plus de 500 bénévoles, ces derniers étaient chargé s de rappeler les patients « non répondants ». Au total, le délai moyen avant prise en charge d’une alerte rouge était de 4,24 minutes et 427 appels SAMU ont été déclenchés par la plateforme, 858 patients ont été hospitalisés et 73 sont décédés.

Conclusion

COVIDOM est un dispositif efficace et sécurisé, simple aisément transposable et reproductible. Il s’agit de la première expérience de télémédecine de cette envergure deployée dans le cadre d’une pathologie infectieuse aiguë. Il a participé à éviter l’engorgement des structures de soin qui ont pu se consacrer à la prise en charge des patients sévères.

Case report study of the first five COVID-19 patients treated with remdesivir in France

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been identified as the virus responsible for the coronavirus disease 2019 (COVID-19) outbreak worldwide. Data on treatment are scare and parallels have been made between SARS-CoV-2 and other coronaviruses. Remdesivir is a broad-spectrum antiviral with efficient in vitro activity against SARS-CoV-2. Evidence of clinical improvement in patients with severe COVID-19 treated with remdesivir is controversial. The aim of this study was to describe the clinical outcomes and virological monitoring of the first five COVID-19 patients admitted to the intensive care unit of Bichat-Claude Bernard University Hospital, Paris, France, for severe pneumonia related to SARS-CoV-2 and treated with remdesivir. Quantitative reverse transcription PCR was used to monitor SARS-CoV-2 in blood plasma and the lower and upper respiratory tract. Among the five patients treated, two needed mechanical ventilation and one needed high-flow cannula oxygen. A significant decrease in SARS-CoV-2 viral load in the upper respiratory tract was observed in most cases, but two patients died with active SARS-CoV-2 replication in the lower respiratory tract. Plasma samples were positive for SARS-CoV-2 in only one patient. Remdesivir was interrupted before the initialy planned duration in four patients, two because of alanine aminotransferase elevations (3 to 5 normal range) and two because of renal failure requiring renal replacement. This case series of five COVID-19 patients requiring intensive care unit treatment for respiratory distress and treated with remdesivir, highlights the complexity of remdesivir use in such critically ill patients.

Evaluation of the QIAstat-Dx Respiratory SARS-CoV-2 Panel, the First Rapid Multiplex PCR Commercial Assay for SARS-CoV-2 Detection

In the race to contain severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), efficient detection and triage of infected patients must rely on rapid and reliable testing. In this work, we performed the first evaluation of the QIAstat-Dx respiratory SARS-CoV-2 panel (QIAstat-SARS) for SARS-CoV-2 detection. This assay is the first rapid multiplex PCR (mPCR) assay, including SARS-CoV-2 detection, and is fully compatible with a non-PCR-trained laboratory or point-of-care (PoC) testing. This evaluation was performed using 69 primary clinical samples (66 nasopharyngeal swabs [NPS], 1 bronchoalveolar lavage fluid sample [BAL], 1 tracheal aspirate sample, and 1 bronchial aspirate sample) comparing SARS-CoV-2 detection with the currently WHO-recommended reverse transcription-PCR (RT-PCR) (WHO-RT-PCR) workflow. Additionally, a comparative limit of detection (LoD) assessment was performed for QIAstat-SARS and WHO-RT-PCR using a quantified clinical sample. Compatibility of sample pretreatment for viral neutralization or viscous samples with the QIAstat-SARS system were also tested. The QIAstat-Dx respiratory SARS-CoV-2 panel demonstrated a sensitivity comparable to that of the WHO-recommended assay with a limit of detection at 1,000 copies/ml. The overall percent agreement between QIAstat-Dx SARS and WHO-RT-PCR on 69 clinical samples was 97% with a sensitivity of 100% (40/40) and specificity at 93% (27/29). No cross-reaction was encountered for any other respiratory viruses or bacteria included in the panel. The QIAstat-SARS rapid multiplex PCR panel provides a highly sensitive, robust, and accurate assay for rapid detection of SARS-CoV-2. This assay allows rapid decisions even in non-PCR-trained laboratory or point-of-care testing, allowing innovative organization.

Clinical impact of tropism testing in a real-life cohort of HIV infected patients: a retrospective observational study

BACKGROUND

The circumstances of prescription of tropism tests clinically relevant in treatment-experienced patients are unclear.

METHODS

We performed a monocentric retrospective analysis of all tropism tests performed between 2006 and 2015 in HIV-infected patients on antiretroviral therapy (ART) without MVC. The motivation of tropism determination was collected. Factors associated with MVC prescription were determined using logistic regression analysis.

RESULTS

Five hundred sixty-three tests were performed in experienced patients not receiving MVC. Reasons for tropism performance were: virological failure (44%), side effects or drug-interactions (37%), simplification or sparing strategies (11%), immunological failure (5%), and improvement of neurological diffusion (3%). MVC was prescribed in 110 cases (20%), though 366 tests (65%) revealed a tropism CCR5. MVC was more often prescribed before 2011 (OR 3.65, 95% CI 2.17-6.13) and in patients with multiple previous ART regimens (less than 4 ART regimens compare to more than 10 ART regimens (OR 0.34, 95% CI 0.15-0.74)).

CONCLUSIONS

In experienced patients not receiving MVC, tropism test prescription should be restricted to patients with virological failure and limited therapeutic options such as patients already treated with a wide range of ART regimens.

Impact of an antimicrobial stewardship programme to optimize antimicrobial use for outpatients at an emergency department

BACKGROUND

Antimicrobial stewardship programmes (ASPs) have been effective in optimizing antibiotic use for inpatients. However, an emergency department's fast-paced clinical setting can be challenging for a successful ASP.

AIM

In April 2015, an ASP was implemented in our emergency department and we aimed to determine its impact on antimicrobial use for outpatients.

METHODS

This was a single-centre study comparing the quality of antibiotic prescriptions between a one-year period before ASP implementation (November 2012 to October 2013) and a one-year period after its implementation (June 2015 to May 2016). For each period, antimicrobial prescriptions for all adult outpatients (hospitalized for <24h) were evaluated by an infectious disease specialist and an emergency department physician to assess compliance with local prescribing guidelines. Inappropriate prescriptions were then classified.

FINDINGS

Before and after ASP, 34,671 and 35,925 consultations were registered at our emergency department, of which 25,470 and 26,208 were outpatients. Antimicrobials were prescribed in 769 (3.0%) and 580 (2.2%) consultations, respectively (P < 0.0001). There were 484 (62.9%) and 271 (46.7%) (P < 0.0001) instances of non-compliance with guidelines before and after ASP implementation. Non-compliance included unnecessary antimicrobial prescriptions, 197 (25.6%) vs 101 (17.4%) (P<0.0005); inappropriate spectrum, 108 (14.0%) vs 54 (9.3%) (P=0.008); excessive treatment duration, 87 (11.3%) vs 53 (9.1%) (P>0.05); and inappropriate choices, 11 (1.4%) vs 15 (2.6%) (P>0.05).

CONCLUSION

The implementation of an ASP markedly decreased the number of unnecessary antimicrobial prescriptions, but had little impact on most other aspects of inappropriate prescribing.

Community acquired fungemia caused by Candida pulcherrima: diagnostic contribution of MALDI-TOF mass spectrometry

BACKGROUND

Community-onset candidemia constitute a distinct clinical entity the incidence of which is increasing. Contribution of non-albicans Candida species is rising.

CASE PRESENTATION

We describe here the first reported case of community acquired fungemia due to Candida pulcherrima. Identification to the species level was performed by MALDI-TOF mass spectrometry. Treatment with fluconazole was successful.

CONCLUSION

This case confirms the pathogenic role of C. pulcherrima and the contribution of MALDI-TOF mass spectrometry for identification of rare Candida species.

Time to initiation of antiretroviral therapy in HIV-infected patients diagnosed with an opportunistic disease: a cohort study

OBJECTIVES

The aim of the study was to identify factors associated with the time between opportunistic disease (OD) diagnosis and antiretroviral therapy (ART) initiation in HIV-infected patients presenting for care with an OD, and to evaluate the outcomes associated with any delay.

METHODS

A multicentre cohort study was undertaken in London, Paris and Lille/Tourcoing. The medical records of patients diagnosed from 2002 to 2012 were reviewed.

RESULTS

A total of 437 patients were enrolled in the study: 70% were male, the median age was 40 years, 42% were from sub-Saharan Africa, 68% were heterosexual, the median CD4 count was 40 cells/μL, and the most common ODs were Pneumocystis pneumonia (37%), tuberculosis (24%), toxoplasmosis (12%) and Kaposi's sarcoma (11%). Of these patients, 400 (92%) started ART within 24 weeks after HIV diagnosis, with a median time from OD diagnosis to ART initiation of 30 [interquartile range (IQR) 16-58] days. Patients diagnosed between 2009 and 2012 had a shorter time to ART initiation than those diagnosed in earlier years [hazard ratio (HR) 2.07; 95% confidence interval (CI) 1.58-2.72]. Factors associated with a longer time to ART initiation were a CD4 count ≥ 200 cells/μL (HR 0.30; 95% CI 0.20-0.44), tuberculosis (HR 0.40; 95% CI 0.30-0.55) and diagnosis in London (HR 0.62; 95% CI 0.48-0.80). Patients initiating 'deferred' ART (by ≥ 30 days) exhibited no difference in disease progression or immunovirological response compared with patients who had shorter times to ART initiation. Patients in the 'deferred' group were less likely to have ART modifications (HR 0.69; 95% CI 0.48-1.00) and had shorter in-patient stays (mean 14.2 days shorter; 95% CI 8.9-19.5 days) than patients in the group whose ART was not deferred.

CONCLUSIONS

The time between OD diagnosis and ART initiation remains heterogeneous and relatively long, particularly in individuals with a high CD4 count or tuberculosis or those diagnosed in London. Deferring ART was associated with fewer ART modifications and shorter in-patient stays.

Correlation between postmortem ethanol levels in the blood and the testicle. A computerized study of 633 determinations

This study emphasizes the value of the presence of ethanol in the testicle. It proves particularly useful in cases where blood and urine are no more present in the body. In 633 cases where blood or urine were still available, a highly positive correlation between the blood, alcohol and the amount of alcohol present in the testicle could be demonstrated, thus confirming the research carried out in the Department of Legal Medicine as far back as 1943. An attempt is further made to assess the possible influence of such factors as putrefaction, submersion or post-traumatic anemia on this correlation.
