RESUMEN

Clindamycin has high bioavailability together with good diffusion in bone tissue and could represent an alternative antibiotic compound for the treatment of bone and joint infections (BJIs). However, data regarding the efficacy and safety of clindamycin for BJIs are limited. A monocentric cohort study based on our medical dashboard, which prospectively recorded 28 characteristics for all hospitalized patients since July 2005, was performed. BJIs were selected, and then, all mono-microbial BJI managed with clindamycin-based therapy were included. Remission was defined as the absence of clinical and/or microbiological relapse after treatment. The duration of follow-up without relapse was determined retrospectively using computerized medical records. For 10 years, 196 BJIs, of which 80 (41%) were device-associated infections, were treated with clindamycin-based therapy. The bacterial causative agent was Staphylococcus aureus in 130 cases (66%), coagulase-negative staphylococci in 29 cases (15%), streptococci in 31 cases (16%) and other bacteria in 6 cases (3%). When used in combination therapy, clindamycin was mainly paired with fluoroquinolones (31%) or rifampin (27%). The mean duration of clindamycin treatment was 7.4 ± 3.2 weeks (range, 1-24). An AE was recorded for 9 (4.5%) patients. Remission was recorded for 111 (57%) patients, with a mean duration of clinical follow-up of 28 ± 24 months. Treatment failure occurred in 22 (11%) patients, 50 patients (25%) were lost to follow-up, and 8 (4%) required long-term suppressive therapy. Among the assessable patients, clindamycin-based therapy was efficient in 111/133 cases (83%) and thus represents a reliable and safe alternative treatment option.

RESUMEN

Daily practice suggests that respiratory signs may be observed in bacteraemic urinary infections (BUI). Our objective was to search for an association between the presence of respiratory symptoms and the bacteraemic nature of urinary tract infections (UTI). A nested case-control study was carried out based on our computerised dashboard from January 2011 to June 2015. Cases were defined as patients with a BUI due to Enterobacteriaceae species, identified in blood and urine cultures. Controls had fever and a positive urinary sample but sterile blood cultures (NBUI) and a final diagnosis of urinary infection. Patients from the BUI group were 1:1 matched to the NBUI group according to four parameters: age, gender, cardiovascular and pulmonary comorbid conditions. Subjects with cognitive impairment limiting clinical accuracy and those with healthcare-associated infections were excluded. We compared systematically recorded respiratory and urinary symptoms between groups: signs on auscultation, dyspnoea, chest pain, cough and sputum, dysuria with burning, pollakiuria, flank or costovertebral angle tenderness and ischuria. One hundred BUI were compared to 100 NBUI, both groups exhibiting a similar rate for all considered comorbid conditions. In the BUI group, 58 % showed at least one respiratory sign vs. 20 % in the NBUI group, p < 0.001, while urinary signs were less frequent: 54 % vs. 71 %, p = 0.013. In the multivariate analysis, BUI was associated with the presence of abnormal pulmonary auscultation [adjusted odds ratio (AOR), 5.91; p < 0.001] and a trend towards less urinary symptoms (AOR, 1.58; p = 0.058). Patients with BUI presented with significantly more respiratory signs, which overshadowed urinary symptoms, compared to those with non-bacteraemic UTI. Such observations impact clinical decision-making.

RESUMEN

Recent data indicate that both the overall numbers of antibiotic prescription and the frequency of multidrug-resistant bacteria are increasing significantly. These threatening features are observed, despite national antimicrobial stewardship (AMS) policies aimed at decreasing antibiotic use. AMS should also focus on the initial steps leading to antibiotic prescription. Physicians and their patients should benefit from the structured clinical pathways, the latter being adapted to regional epidemiological data and resources. Continuous evaluation of these predefined clinical paths through a computerized medical dashboard will allow a critical review and finally the optimization of medical practices. These innovative behavioural approaches for clinicians will supply precise information on the relationship among the diagnosis, therapeutics and outcome. This changing environment will carry out the adapted therapeutic procedures, and appropriate antibiotic use will inherently improve.

RESUMEN

Guidelines for inpatients with community-acquired pneumonia (CAP) propose to use respiratory fluoroquinolone (RFQ) and/or third-generation cephalosporins (Ceph-3). However, broad-spectrum antibiotic therapy is associated with the emergence of drug-resistant bacteria. We established a guideline in which RFQ and Ceph-3 were excluded as a first course. Our aim was to evaluate the impact of our therapeutic choices for CAP on the length of hospital stay (LOS) and patient outcome. This was a cohort study of patients with CAP from July 2005 to June 2014. We compared patients benefiting from our guideline established in 2008 to those receiving non-consensual antibiotics. Disease severity was evaluated through the Pneumonia Severity Index (PSI). The empirical treatment for PSI III to V was a combination therapy of amoxicillin-clavulanic acid (AMX-C) + roxithromycin (RX) or AMX + ofloxacin. Adherence to guidelines was defined by the prescription of one of these antibiotic agents. Requirement for intensive care or death defined unfavorable outcome. Among 1,370 patients, 847 were treated according to our guideline (61.8 %, group 1) and 523 without concordant therapy (38.2 %, group 2). The mean PSI was similar: 82 vs. 83, p > 0.5. The mean LOS was lower in group 1: 7.6 days vs. 9.1 days, p < 0.001. An unfavorable outcome was less frequent in group 1: 5.4 % vs. 9.9 %, p = 0.001. In logistic regression models, concordant therapy was associated with a favorable outcome: adjusted odds ratio (AOR) [95 % confidence interval (CI)] 1.85 [1.20-2.88], p = 0.005. CAP therapy without RFQ and Ceph-3 use was associated with a shorter LOS and fewer unfavorable outcomes.

RESUMEN

Acute respiratory distress syndrome (ARDS) in humans is characterized by the infiltration of polymorphonuclears in the alveolar spaces. However, the role of T-cells in ARDS is unknown. Our aim was to characterize the T-cell phenotype in bronchoalveolar lavage (BAL) during the early phase of acute lung infection(ALI)/ARDS-infected patients in comparison to a control group (CG). BAL lymphocyte phenotypes of two ALI, 16 ARDS, and eight CG were examined by flow cytometry. ALI/ARDS showed a significant increase in CD4 and CD8 T-cell activation as compared to CG. Moreover, a significant level of proliferation was observed using the Ki67 marker in ARDS patients as compared to controls (median): 37 versus 6 % for CD4 T-cells (p = 0.022) and 34 versus 2 % for CD8 T-cells (p = 0.009). In contrast, the percentage of T-regulatory cells and apoptotic T-cells were similar in both groups. Among costimulatory molecules, we observed an overexpression of CTLA-4/CD152 on CD4 T-cells in ALI/ARDS as compared to CG: 30 versus 7 %, respectively (p = 0.063). In further characterizing T-cell subsets expressing high levels of CD152, we found the presence of IL-17 secreting CD4 T-cells in ALI/ARDS. In humans, ALI/ARDS due to infection is associated with a high level of T-cell activation and proliferation, along with the presence of Th17 cells, which are known to attract polymorphonuclears.

RESUMEN

Positive urinary antigen tests (UAT) for pneumococcal infection in community-acquired pneumonia (CAP) may lead to targeted antibiotic therapy. We report an audit aimed at defining the link between mortality and targeted therapy. We conducted a retrospective multicentre audit of patients with severe CAP for whom a UAT was positive for S. pneumoniae. Patients admitted from January 2010 to December 2013 to 8 medical centres (from A to H) were included. Co-morbidities were defined by the specific treatment administered before hospital care, or if the diagnosis was newly established during the hospital stay. We used the Pneumonia Severity Index (PSI) to assess disease severity. Only patients with PSI > 90 were included. Antibiotic treatments and the PSI were extracted from patients' charts. Amoxicillin had to be prescribed as a targeted antibiotic treatment or at the time of antibiotic reassessment. A total of 389 patients were included. The mean (±STD) PSI score was 128 ± 29; 38.9% of the patients had a class 5 PSI score. Intensive care was required for 36.6% of the patients. Amoxicillin was initially prescribed in 47 cases (12.1%) and in 34 cases after reassessment (8.7%). In logistic regression analysis, we found three parameters associated with mortality: being hospitalised in institution D, class 5 PSI score, and metastatic cancer. In contrast, three antibiotic regimens were protective factors, including targeted therapy: OR = 0.09, p < 0.001. In the context of severe CAP with positive UAT for S. pneumoniae, targeted therapy was associated with a reduction in mortality.

RESUMEN

Chronic bone infection is associated with bone resorption. From animal studies, CD3/CD28-activated T cells are known to enhance osteoclastogenesis and bone resorption. Because CD28 is expressed constitutively on T cells and its expression is down-regulated by chronic exposure to the inflammatory environment, we characterized co-stimulatory molecule expression on T cells from chronically infected patients. We used cytofluorometric techniques to phenotypically characterize T cells, its co-stimulatory molecules and perforin secretion from infected and non-infected human bones. Chronic bone infection was defined as infection lasting for more than a month. We show a higher T cell activation [human leucocyte antigen D-related (HLA-DR⁺)] in infected compared to non-infected bones: median being 16 versus 7%, P = 0·009 for CD4 T cells, and 33 versus 15%, P = 0·038 for CD8 T cells, respectively. However, T cell proliferation (Ki67⁺) was lower for CD8 T cells in infected bones: 26 versus 34%, P = 0·045. In contrast, we detected no difference in apoptosis and regulatory T cells. In infected bone, we found higher CD28-negative CD4⁺ T cells compared to non-infected bone: 20 versus 8%, respectively (P = 0·005); this T cell subset had higher CD11b expression and perforin secretion. Chronically infected human bones are characterized by an increase of CD28-negative CD4⁺ T cells, indicating long-term activated cells with cytotoxic ability. Therefore, this alteration of co-stimulatory molecules may modify interactions with osteoclasts and impact bone resorption.

RESUMEN

Antibiotics are a significant cause of adverse events (AE), but few studies have focused on prescriptions in hospitalized patients. In infectious diseases departments, the high frequency and diversity of antibiotics prescribed makes AE post-marketing monitoring easier. The aim of our study was to assess the incidence and type of AE in the infectious diseases department of a French teaching tertiary-care hospital. The main characteristics of each hospitalization, including all antibiotics prescribed and any significant AE were recorded prospectively in the medical dashboard of the department. We included all patients having suffered an AE due to systemic antibiotics between January 2008 and March 2011. Among the 3963 hospitalized patients, 2682 (68%) received an antibiotic and 151/2682 (5.6%) suffered an AE. Fifty-two (34%) AE were gastrointestinal disorders, 32 (21%) dermatological, 20 (13%) hepatobiliary, 16 (11%) renal and urinary disorders, 13 (9%) neurological and 11 (7%) blood disorders. Rifampin, fosfomycin, cotrimoxazole and linezolid were the leading causes of AE. Sixty-two percent of the antibiotics causing an AE were stopped and 38% were continued (including 11% with a dose modification). Patients suffering from AE had an increased length of stay (18 vs 10 days, P < 0.001). Our data could help choosing the safest antibiotic when several options are possible.

RESUMEN

INTRODUCTION: Teleconsultation is an emerging tool whose utilization dramatically increased during the Covid-19 pandemic. Our aim was to determine its clinical accuracy. METHODS: This prospective study was carried out during the first wave of Covid-19. Patients were teleconsulted by either general practitioners or emergency doctors reporting clinical exam results to the ID physicians by phone. Five signs were specifically checked: dyspnea, fever, cough, anosmia and flu-like illness. Data collected by remote consultation were compared to face-to-face examination in an ID Department. RESULTS: From March to April 2020, 149 patients were seen by remote medical care. Dyspnea was found in 14.1% of the teleconsultation patients vs 3.4% in face-to-face consultation; fever in 47.0 vs. 15.4%; cough in 69.1 vs. 16.1%; anosmia in 3.4 vs. 1.3%; flu-like illness in 53.0 vs. 7.4% (all differences significant: P<0.001). CONCLUSION: We observed incongruency between remote and face-to-face consultation for the main clinical signs of Covid-19.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: We reported the impact of internal guidelines coupled with selective reporting of antibiotic susceptibility tests (srAST) on antibiotic adequacy in healthcare facilities. METHODS: This prospective study involved clinicians from three clinics with medical and surgical activities employing a full-time infectious disease (ID) specialist. Internal guidelines were updated in 2016. The clinics were working with the same laboratory, which delivered the srAST introduced in March 2017. Two weeks per month over a 6-month period, all isolated bacterial specimens, empirical antibiotic therapies (EAT) and the documented ones were analyzed. An EAT listed in the guidelines and a documented therapy mentioned in the srAST defined their adequacy. RESULTS: A total of 257 positive bacterial samples were analyzed in 199 patients, for which 106 infections were studied. Of these, 32% were urinary tract infections, 15% were primary bloodstream infections, 11% were bone infections, and 42% were other types of infection. The three main bacteria were Escherichia coli (27%), Staphylococcus aureus (24%), and Enterococcus faecalis (14%). The total number of antibiotic prescriptions was 168, with 75 (45%) EATs and 93 (55%) documented therapies. There were 35/75 (47%) adequate EATs and 86/93 (92%) adequate documented therapies. The ID specialist was not involved in 90/168 (53.5%) prescriptions, of which 43/90 (48%) were adequate, with 21/35 (60%) EATs and 22/86 (25%) documented therapies. There was a statistical correlation between compliance of the EATs with guidelines and of the documented therapy with srAST (p=0.02). CONCLUSION: Combining internal guidelines and srAST led to a high rate of antibiotic adequacy.

RESUMEN

There is no consensus on the antibiotic therapy for bone infection due to the heterogeneous spectrum of diseases. Most authors suggest different durations of treatment based on pathophysiological considerations. However, adverse effects are related, at least in part, to the duration of treatment. We, therefore, investigated a 6 weeks antibiotic combination therapy for all cases of bone infection. Herewith, we report the results of this therapeutic approach. This is a cohort study including all patients presenting with bone infection, regardless of the mechanism involved. The diagnosis was based on bone biopsy obtained through invasive procedures. Chronic bone infection was defined as a history of disease of over 1 month duration. The duration of clinical follow-up following treatment discontinuation was at least 6 months. Cured bone infection was defined as the absence of relapse after antibiotic discontinuation. One hundred and eighteen patients were included between July 2005 and March 2009; 61 presented with bone infection following prosthetic implant (52%) and the 57 remaining patients had bone infection without foreign material (48%). Surgery was required for 80 patients (68%). Microbial agents were identified in 116/118 patients, with 24 patients presenting with polymicrobial sepsis (20%). The mean duration of antibiotic treatment was 42 +/- 0.2 days and the mean clinical follow-up was 27 +/- 14 months. The treatment success rate was 91.5% (108/118). Six weeks of antimicrobial therapy appears to be effective for nearly all bone infections, regardless of the pathophysiology. These results encourage us to pursue attempts to simplify the management of bone infection without obvious prejudice to the patient.

RESUMEN

OBJECTIVE: To evaluate the therapeutic utility of the viral load (VL) measurement after one month (M1) of antiretroviral (ARV) treatment. PATIENTS AND METHOD: A retrospective study of HIV patients included in the NADIS database from 1998 to 2006 and followed at Nice University Hospital. We included ARV-naive patients who received ARV (3-drug combination) for at least 3 months and ARV-experienced patients beginning a new ARV after virologic failure. RESULTS: The NADIS database included 1065 patients from 1998 to 2006. We included 262. In all, 234 of them had VL measured at M1 and are considered in this analysis. Their mean age was 44 years, and 174 were men, for a sex ratio of 9.1. ARV-naïve patients accounted for 35% of the sample (n = 81) and previously treated patients 65% (n = 153). All the naive patients had a VL decrease at M1 > 1 log, as did all but 14 of the previously treated patients (9%). This virological result was followed by a medical action 21 times for the naive patients and 97 times for the previously treated patients (p < 0.004). CONCLUSION: The VL measurement at M1 indicates a virological objective that was reached for all the naive patients and 91% of the previously treated patients. Moreover, the medical actions taken at M1 for a new ARV treatment appear to be associated with the patient's treatment history and not the virological results.

T-cell apoptosis during septic shock (SS) has been associated with deleterious outcome, but the mechanisms of apoptosis are not well understood. As T-cells are not infected in bacterial infection, our hypothesis was that deleterious interactions between lymphocytes and monocytes could be involved. This is a cross-sectional study of 27 patients presenting with community-acquired SS, 23 infected patients without SS and 18 controls. Cytofluorometric techniques were used to study apoptosis, the costimulatory pathway and cytokine synthesis. Apoptosis was increased in SS compared to infected patients without SS and controls: the median values were 18, 2 and 3%, respectively, for CD4(+) T-cells (P < 0.001), and 12, 5 and 2%, respectively, for CD8(+) T-cells (P < 0.001). Patients with SS exhibited significant CD152 over-expression on T-cells, while CD86 expression was decreased on monocytes (P = 0.004). The synthesis of interleukin-2 was decreased in patients with SS compared to the other groups, while secretions of interferon-gamma and TNF-alpha were not altered. Ten surviving patients with SS showed a trend towards the normalisation of these parameters on day 7. In SS, T-cell apoptosis is related, at least in part, to the alteration of the costimulatory pathway, which, in turn, leads to significant modification of the cytokine network.

RESUMEN

UNLABELLED: Monitoring of body temperature, but also of C-reactive protein (CRP) level is performed in infected patients treated with antibiotics. These two parameters having low specificity for any diagnosis, our aim was to evaluate the usefulness of CRP in this context. PATIENTS AND METHOD: A representative sample of patients was randomly extracted from our medical computerized tables. All patients presented community-acquired infections and had at least two CRP level assessments. Kinetics of body temperature and CRP allowed to quantify clinical and biological discrepancy while the patient's chart was studied to determine the etiologies. RESULTS: Three hundred and ninety-two patients over 942 (42%) were admitted in our department over 2 years, including 147 cases of respiratory infections (37%), 91 of urinary infections (23%), 65 of cellulitis (17%), 70 of primary bacteremia (18%), 19 of digestive infections (5%). Ninety-four percent of the patients had been prescribed antibiotic therapy. We observed a correlation between temperature and CRP in 83% of the patients. Forty-seven percent of patients presented with normalized body temperature and persistently high levels of CRP, which was most of the time related to comorbid conditions. Twenty patients (5%) presented with unexplained persistent fever despite CRP normalization. Therapeutic modifications were mostly observed in the presence of clinicobiological discrepancy: 21% versus 6%, p<0.001. DISCUSSION: Body temperature and CRP are two parameters leading to comparable information in more than 80% of infected patients receiving specific antibiotic therapy. These clinical and biological discrepancies are associated to a modified antibiotherapy with inconclusive results.

RESUMEN

Responsible pathogens of chronic bone infections (CBI) are frequently resistant, requiring parenteral antimicrobial therapy. Therefore, adverse effects may be observed. We have determined the rate of adverse effects of antimicrobial therapy for CBI in a retrospective study of all patients receiving parenteral drugs via an implantable port. Patients from one medical ward (n = 89) and from one surgical ward (n = 40) between January 1995 and December 2005 were included in this study. The CBI included were 85 osteomyelitis (66%) and 44 prosthetic joint infections (34%). The main group of pathogens was gram positive cocci (n = 144; 65%). The total duration of antibiotic treatment was 205 +/- 200 days, including 133 +/- 100 days for parenteral therapy. Thirty-three catheter-related complications were observed in 27 patients (21%). All complications led to hospitalization but none led to death. Twenty-one antibiotic-related complications occurred in 18 patients (16%), and one allergic reaction led to death. The mean duration of follow-up was 290 days. Remission was observed in 84 patients (65%). In multivariate analysis, adverse effects were mostly observed in the medical department. Adverse effects affect at least one third of the patients treated for CBI with parenteral antimicrobial therapy and are related to both the implantable port and the antibiotic compounds.

RESUMEN

The current French hospital reform is based on the disease-related group (DRG) approach and the constitution of bigger units pooling several departments of different specialties. This reform needed an efficient assessment of various medical activities. We report our experience of a medical table of our hospital activities used for 27 months. This medical table was made with a basic software integrating 24 parameters. The original concept was the translation of the specific final diagnosis for DRG defined by the site of infection. To create this medical table, we first simplified the conclusions of the patient's chart using a consensual and systematic plan. The number of patients per DRG and their evolution were therefore specifically determined. The medical table helped us in the daily management of our department, to identify the area of recruitment, the potential for heterogeneous care, allowing the implementation of protocols and their applications. Moreover, the table quantified morbidity and mortality, indicating our need for cooperation with other departments. All this data used medical-lexical terms, allowing other than economic analyses, even if this table identifies hospitalization-related costs, namely duration of hospital-stay, nosocomial infections and iatrogenic events. Finally, our table supports medical research and evaluation of practice. Our future goals are to introduce this table in several infectious-diseases units, and create specific tables for the main RDG, including economic parameters.
