Background: Nitrofurantoin is the first-choice antibiotic treatment for uncomplicated urinary tract infections (UTIs) in males according to the Dutch primary care UTI guideline. However, prostate involvement may be undetected and renders this treatment less suitable.
Aim: To compare the nitrofurantoin failure fraction with that found with use of other antibiotics in adult males diagnosed by their GP with an uncomplicated UTI, as well as GP adherence to the Dutch primary care UTI guideline.
Design And Setting: Retrospective observational cohort study using routine healthcare data for males seeking care at GP practices participating in the Julius GP Network from 2014 to 2020.
Method: Medical records were screened for signs and symptoms of complicated UTIs, antibiotic prescriptions, and referrals. Treatment failure was defined as prescription of a different antibiotic within 30 days after initiation of antibiotic therapy and/or acute hospital referral. The effects of age and comorbidities on failure were assessed using multivariable logistic regression.
Results: Most UTI episodes in males were uncomplicated ( = 6805/10 055 episodes, 68%). Nitrofurantoin was prescribed in 3788 (56%) of uncomplicated UTIs, followed by ciprofloxacin ( = 1887, 28%), amoxicillin/clavulanic acid ( = 470, 7%), and trimethoprim/sulfamethoxazole ( = 285, 4%). Antibiotic failure occurred in 25% (95% confidence interval [CI] = 23 to 26), 10% (95% CI = 9 to 12), 20% (95% CI = 16 to 24), and 14% (95% CI = 10 to 19) of episodes, respectively. The nitrofurantoin failure fraction increased with age. Comorbidities, adjusted for age, were not associated with nitrofurantoin failure.
Conclusion: Nitrofurantoin failure was common in males with uncomplicated UTI and increased with age.

Reassessing the management of uncomplicated urinary tract infection: A retrospective analysis using machine learning causal inference.

Background: Uncomplicated urinary tract infection (UTI) is a common indication for outpatient antimicrobial therapy. National guidelines for the management of uncomplicated UTI were published by the Infectious Diseases Society of America in 2011, however it is not fully known the extent to which they align with current practices, patient diversity, and pathogen biology, all of which have evolved significantly in the time since their publication.
Objective: We aimed to re-evaluate efficacy and adverse events for first-line antibiotics (nitrofurantoin, and trimethoprim-sulfamethoxazole), versus second-line antibiotics (fluoroquinolones) and versus alternative agents (oral β-lactams) for uncomplicated UTI in contemporary clinical practice by applying machine learning algorithms to a large claims database formatted into the Observational Medical Outcomes Partnership (OMOP) common data model.

Urinary tract infections (UTIs) caused by represent a significant public health concern due to the high virulence and antimicrobial resistance exhibited by these pathogens. This study aimed to analyze the phylogenetic diversity and antibiotic resistance profiles of Uropathogenic (UPEC) strains isolated from UTI patients in Algeria, focusing on virulence factors such as extended β-lactamase (ESBL) production, biofilm formation, and hemolytic activity. Phylogenetic grouping of 86 clinical imipenem resistant isolates showed the prevalence of group B2 (48.

Background: In low- and middle-income countries, symptomatic urinary tract infection (UTI) patients are often prescribed antibiotics without microbiological confirmation. UTIs caused by antibiotic-resistant bacteria are increasingly common, and this heightens the risk of empirical treatment failure. This study evaluates the appropriateness of empirical antibiotic therapy to UTI patients in Nairobi County, Kenya.

Nitrofurantoin is the antibiotic of choice for treatment and prophylaxis of recurrent episodes of lower urinary tract infections. Although adverse effects such as anorexia, vomiting, and pulmonary hypersensitivity are commonly reported with nitrofurantoin use, studies have demonstrated that rarely nitrofurantoin can also induce diverse forms of liver injury, spanning from mild hepatitis to severe and potentially fatal fulminant liver failure. These occur especially in elderly females with preexisting liver or renal impairment.

Article Synopsis
- A comprehensive study analyzed 468 cases of idiosyncratic drug-induced liver injury (DILI) in Latin America over a decade, revealing key demographic details such as a predominance of women (62%) and a mean age of 49 years.
- The analysis found that hepatocellular injury was the most common (62%), with significant occurrences of jaundice (60%) and hospitalization (42%), while 4.1% of cases resulted in fatal outcomes.
- The study highlights a rising incidence of liver injuries linked to herbal and dietary supplements, as well as specific drugs like nimesulide and nitrofurantoin, suggesting the need for public health initiatives to educate on the risks associated with these medications.
