Antibiotic Resistance in Paediatric Febrile Urinary Tract Infections

: Febrile urinary tract infection (UTI) is currently considered the most frequent cause of serious bacterial illness in children in the first 2 years of life. UTI in paediatrics can irreversibly damage the renal parenchyma and lead to chronic renal insufficiency and related problems. To avoid this risk, an early effective antibiotic treatment is essential. Moreover, prompt treatment is mandatory to improve the clinical condition of the patient, prevent bacteraemia, and avoid the risk of bacterial localization in other body sites. However, antibiotic resistance for UTI-related bacterial pathogens continuously increases, making recommendations rapidly outdated and the definition of the best empiric antibiotic therapy more difficult. Variation in pathogen susceptibility to antibiotics is essential for the choice of an effective therapy. Moreover, proper identification of cases at increased risk of difficult-to-treat UTIs can reduce the risk of ineffective therapy. In this review, the problem of emerging antibiotic resistance among pathogens associated with the development of paediatric febrile UTIs and the best potential solutions to ensure the most effective therapy are discussed. Literature analysis showed that the emergence of antibiotic resistance is an unavoidable phenomenon closely correlated with the use of antibiotics themselves. To limit the emergence of resistance, every effort to reduce and rationalise antibiotic consumption must be made. An increased use of antibiotic stewardship can be greatly effective in this regard

Grisel’s Syndrome in Children: Two Case Reports and Systematic Review of the Literature

Background and Objective. Grisel’s syndrome is a rare syndrome characterized by nontraumatic rotatory subluxation of the atlantoaxial joint. It usually affects children and typically presents with torticollis after ear, nose, and throat (ENT) surgery or head and neck infections. In the pediatric literature, there is only a small amount of available data; moreover, no systematic review has been previously done with focus on the pediatric population. We report our experience of two cases, and we provide a systematic review on Grisel’s syndrome in children in order to offer a deeper insight about its clinical presentation, its current diagnosis, and principles of treatment. Case Reports and Review. We describe two boys of 9 and 8 years old, who developed atlantoaxial subluxation after adenoidectomy. Considering the early diagnosis, a conservative treatment was chosen, with no recurrence and no sequelae at follow-up. We identified 114 case reports, of which 90 describe children, for a total of 171 pediatric patients. Of the 154 cases in which cause was reported, 59.7% presented a head and neck infection and 35.7% had previous head and neck surgery. There is no sex prevalence (49.7% males versus 50.2% females). Mean delay in diagnosis is 33 days. Eight % of the patients had neurological impairment of the 165 cases which mentioned treatment, 96% underwent a conservative treatment, of whom the 8.8% recurred with the need of surgery. As a whole, 12% underwent surgery as a first- or second-line treatment. 3 6% of the patients whose follow-up was reported developed a sequela, minor limitation of neck movement being the most frequent. Conclusion. Grisel’s syndrome should be suspected in children with painful unresponsive torticollis following ENT procedures or head and neck inflammation. CT scan with 3D reconstruction is the gold standard for diagnosis, allowing the identification of the subluxation and the classification according to the Fielding–Hawkins grading system. Surgical treatment is indicated in case of high-grade instability or failure of conservative treatment. Review of the literature shows how early diagnosis based on clinical and radiological evaluation is crucial in order to avoid surgical treatment and neurologic sequelae

Clinical Outcome of Discordant Empirical Therapy and Risk Factors Associated to Treatment Failure in Children Hospitalized for Urinary Tract Infections

With the spread of antibiotic resistance in pediatric urinary tract infections (UTIs), more patients are likely to be started empirically on antibiotics to which pathogens are later found to be resistant (discordant therapy). However, in-vivo effectiveness may be different from in-vitro susceptibility. Aims of this study were to describe clinical outcomes of discordant empirical treatments in pediatric UTIs and to investigate risk factors associated to treatment failure. This observational, retrospective study was conducted on children hospitalized for febrile UTIs with positive urine culture and started on discordant empirical therapy. Failure rates of discordant treatments and associated risk factors were investigated. A total of 142/1600 (8.9%) patients were treated with inadequate empirical antibiotics. Clinical failure was observed in 67/142 (47.2%) patients, with no fatal events. Higher failure rates were observed for combinations of penicillin and beta-lactamase inhibitors (57.1%). Significant risk factors for failure of discordant treatment were history of recurrent UTIs (95% CI: 1.13–9.98, OR: 3.23, p < 0.05), recent use of antibiotics (95% CI: 1.46–21.82, OR: 5.02, p < 0.01), infections caused by Pseudomonas aeruginosa (95% CI: 1.85–62.10, OR: 7.30, p < 0.05), and empirical treatment with combinations of penicillin and beta-lactamase inhibitors (95% CI: 0.94–4.03, OR: 1.94, p = 0.05). This study showed that discordant empirical treatments may still be effective in more than half of pediatric UTIs. Clinical effectiveness varies between different discordant antibiotics in pediatric UTIs, and patients presenting risk factors for treatment failure may need a differentiated empirical approach

Retrospective 8-Year Study on the Antibiotic Resistance of Uropathogens in Children Hospitalised for Urinary Tract Infection in the Emilia-Romagna Region, Italy

The development and spread of antibiotic resistance is an increasingly important global public health problem, even in paediatric urinary tract infection (UTI). In light of the variability in the data, it is necessary to conduct surveillance studies to determine the prevalence of antibiotic resistance in specific geographical areas to optimize therapeutic management. In this observational, retrospective, multicentre study, the medical records of 1801 paediatric patients who were hospitalised for UTI between 1 January 2012, and 30 June 2020, in Emilia-Romagna, Italy, were analysed. Escherichia coli was the most frequently detected pathogen (75.6%), followed by Klebsiella pneumoniae (6.9%) and Pseudomonas aeruginosa (2.5%). Overall, 840 cases (46.7%) were due to antimicrobial-resistant uropathogens: 83 (4.7%) extended spectrum beta-lactamase (ESBL)-producing, 119 (6.7%) multidrug resistant (MDR) and 4 (0.2%) extensively drug resistant (XDR) bacteria. Empirical antibiotic therapy failed in 172 cases (9.6%). Having ESBL or MDR/XDR uropathogens, a history of recurrent UTI, antibiotic therapy in the preceding 30 days, and empirical treatment with amoxicillin or amoxicillin/clavulanate were significantly associated with treatment failure, whereas first-line therapy with third-generation cephalosporins was associated with protection against negative outcomes. In conclusion, the increase in the resistance of uropathogens to commonly used antibiotics requires continuous monitoring, and recommendations for antibiotic choice need updating. In our epidemiological context, amoxicillin/clavulanate no longer seems to be the appropriate first-line therapy for children hospitalised for UTI, whereas third-generation cephalosporins continue to be useful. To further limit the emergence of resistance, every effort to reduce and rationalise antibiotic consumption must be implemented
