Abstract
PURPOSE Few data have been published on the efficacy of linezolid in enterococcal urinary tract infection (e-UTI). The aims of this study were to describe the characteristics of patients with enterococci UTI treated with linezolid, and to evaluate the efficacy and the tolerance of linezolid treatment. METHODS An observational multicentre retrospective study was conducted in 5 hospitals in France. Patients were included if they met the following criteria: ≥18 years, clinical and microbiological criteria for enterococcal UTI and linezolid treatment > 48 h. Primary outcome was clinical failure. RESULTS Eighty-one patients were included between January 2015 and December 2021. The median age was 73.0 [64; 83] years and 47 (58%) were men. The median Charlson comorbidity index was 3.00 [2; 6]. E. faecium was reported in 65 (80%) cases and E. faecalis in 26 cases (32%). Polymicrobial infections occurred in 41 (51%) cases. No enterococci was resistant to vancomycin. Before linezolid prescription an empiric antimicrobial treatment was started in 48 (59%) cases and was effective against enterococci in 19/48 (39.5%) patients for a median of 3.5 days [2.0; 4.0]. The median duration of linezolid antibiotic treatment was 13 days [10; 14]. Three adverse events were reported, none were serious but one led to discontinuation of treatment. Treatment failure was reported in 2 cases (2.5%). CONCLUSION This study provides evidence for efficacy and safety of linezolid in enterococcal UTI.

Factors associated with urinary diversion and fatality of hospitalised acute pyelonephritis patients in France: a national cross-sectional study (FUrTIHF-2). Epidemiol Infect 2023; 151:e161. [PMID: 37721009 PMCID: PMC10600899 DOI: 10.1017/s0950268823001504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 09/04/2023] [Accepted: 09/05/2023] [Indexed: 09/19/2023] Open
Abstract
Acute pyelonephritis (AP) epidemiology has been sparsely described. This study aimed to describe the evolution of AP patients hospitalised in France and identify the factors associated with urinary diversion and fatality, in a cross-sectional study over the 2014-2019 period. Adult patients hospitalised for AP were selected by algorithms of ICD-10 codes (PPV 90.1%) and urinary diversion procedure codes (PPV 100%). 527,671 AP patients were included (76.5% female: mean age 66.1, 48.0% Escherichia coli), with 5.9% of hospital deaths. In 2019, the AP incidence was 19.2/10,000, slightly increasing over the period (17.3/10,000 in 2014). 69,313 urinary diversions (13.1%) were performed (fatality rate 6.7%), mainly in males, increasing over the period (11.7% to 14.9%). Urolithiasis (OR [95% CI] =33.1 [32.3-34.0]), sepsis (1.73 [1.69-1.77]) and a Charlson index ≥3 (1.32 [1.29-1.35]) were significantly associated with urinary diversion, whereas E. coli (0.75 [0.74-0.77]) was less likely associated. The same factors were significantly associated with fatality, plus old age and cancer (2.38 [2.32-2.45]). This nationwide study showed an increase in urolithiasis and identified, for the first time, factors associated with urinary diversion in AP along with death risk factors, which may aid urologists in clinical decision-making.

Front Public Health 2023; 11:1161550.

Abstract
The development of medico-administrative databases over the last few decades has led to an evolution and to a significant production of epidemiological studies on infectious diseases based on retrospective medical data and consumption of care. This new form of epidemiological research faces numerous methodological challenges, among which the assessment of the validity of targeting algorithm. We conducted a scoping review of studies that undertook an estimation of the completeness and validity of French medico-administrative databases for infectious disease epidemiological research. Nineteen validation studies and nine capture-recapture studies were identified. These studies covered 20 infectious diseases and were mostly based on the evaluation of hospital claimed data. The evaluation of their methodological qualities highlighted the difficulties associated with these types of research, particularly those linked to the assessment of their underlying hypotheses. We recall several recommendations relating to the problems addressed, which should contribute to the quality of future evaluation studies based on medico-administrative data and consequently to the quality of the epidemiological indicators produced from these information systems.

Predictors of ultrasound abnormalities among women treated for community-onset acute pyelonephritis: a prospective study. World J Urol 2022; 40:2499-2504. [PMID: 36053308 DOI: 10.1007/s00345-022-04112-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Accepted: 07/14/2022] [Indexed: 10/14/2022] Open
Abstract
OBJECTIVES Acute pyelonephritis (AP) is a common but potentially severe infection. It may be complicated by pyelocaliceal dilatation which requires emergency urine drainage. In outpatient care, ultrasound (US) appears to be the easier way to diagnose pyelocaliceal dilatation, though most APs will not be complicated and do not require immediate ultrasound. We aimed to identify predictors of ultrasound abnormalities in an outpatient AP cohort. METHODS A prospective study was conducted from April 2006 to September 2019 in an outpatient care network. Patients aged 15 and over treated for AP were included. Men, pregnant women, patients with solitary kidney, and patients without data on their management were excluded. A common algorithm ensured the same approach from diagnosis to treatment. Data were collected prospectively in an anonymized database. We described the characteristics of the patients. Univariate and then multivariate analyses were performed to identify predictors of ultrasound abnormalities. RESULTS 2054 women were treated for AP. Among them, 32.5% (n = 667) had a history of urinary tract infections and 5.8% (n = 120) of uropathy. The most frequent uropathogen was E. coli (n = 1,432; 69.7%); Extended-Spectrum Beta-Lactamases (ESBLs) were found in 39 (1.9%) urine cultures. Ultrasound was abnormal in 7.3% (n = 149). Age over 55 years (OR = 2.23; 95% CI 1.58‒3.15; p < 0.0001) and uropathy (OR = 3.69; 95% CI 2.26‒6.01; p < 0.0001) were independently identified as predictors of ultrasound abnormalities. The risk increased by 1.8% (95% CI 1.0‒2.6) with each additional year of age. CONCLUSIONS This study identified age and uropathy as independent predictors of abnormal ultrasound in women treated with community-onset AP.
