Background: Pelvic inflammatory disease (PID) is a common and potentially severe infection of the upper genital tract. Complications such as tubo-ovarian abscess (TOA), sepsis, and diffuse peritonitis contribute significantly to reproductive morbidity, particularly when diagnosis or treatment is delayed. Aim: The aim of this review is to present an updated, clinically relevant synthesis of the current evidence on the epidemiology, microbiology, diagnostic approach, imaging modalities, and management of PID, with a focus on severe forms including TOA, sepsis, and peritonitis. Content: PID is most frequently initiated by sexually transmitted pathogens—primarily Chlamydia trachomatis and Neisseria gonorrhoeae—which rapidly progresses to a polymicrobial infection involving anaerobic and enteric organisms. Diagnosis is predominantly clinical, supported by nucleic acid amplification tests, inflammatory markers, and imaging. Transvaginal ultrasonography remains the first-line diagnostic approach for suspected TOA, while CT or MRI is reserved for unclear cases or to assess rupture. Mild to moderate disease is managed with broad-spectrum combination antibiotics, whereas severe PID or TOA requires hospitalization, parenteral therapy, and timely source control through image-guided drainage or surgery. Ruptured abscesses and PID-associated sepsis demand urgent surgical intervention and multidisciplinary supportive care. Tailored approaches are necessary in pregnancy, adolescence, and immunosuppressed and postmenopausal patients. Conclusions: Prompt recognition, a low threshold for empiric antimicrobial therapy, the appropriate use of imaging, and decisive escalation to drainage or surgery are essential to limit morbidity and preserve reproductive health. Integrating guideline-based practice with structured clinical pathways may improve outcomes and reduce long-term sequelae of PID. Full article

Background: The inappropriate and empirical use of antibiotics in early childhood remains a major global public health concern, contributing significantly to the rise of antimicrobial resistance (AMR). In Kosovo, the COVID-19 pandemic further influenced prescribing behaviors in primary care, increasing the reliance on symptom-based treatment in the absence of laboratory confirmation and age-appropriate formulations. Aim: This study aimed to assess the prevalence and patterns of antibiotic prescribing among children aged 1–7 years in primary health care centers in Prishtina and Ferizaj from January 2022 to December 2025, and to compare regional differences in prescribing practices and guideline adherence. Methods: A retrospective observational study was conducted using data from the national electronic health record system and protocol books. All pediatric visits for children aged 1–7 years with infectious diagnoses were included. Descriptive statistics, Chi-square tests, and multivariable logistic regression were used to evaluate prescribing prevalence, demographic and seasonal variations, and independent predictors of antibiotic use, including assessment of appropriateness based on international pediatric guidelines. Results: Of 4320 pediatric visits, 1328 (30.7%) resulted in an antibiotic prescription. Prescribing prevalence was higher in Ferizaj (34.2%) than in Prishtina (28.5%, p < 0.01). Amoxicillin–clavulanic acid (42.9%) and amoxicillin (21.5%) were the most frequently prescribed agents, while macrolides (11.7% vs. 6.2%) and cephalosporins (7.9% vs. 3.4%) were more common in Ferizaj. Only 61.4% of prescriptions were fully guideline-concordant. Younger age (1–3 years), winter season, and residence in Ferizaj were independently associated with higher odds of receiving an antibiotic. Conclusions: Pediatric antibiotic prescribing in Kosovo remains high and predominantly empirical, reflecting real-world limitations in diagnostic capacity and formulation availability. Significant proportions of partially appropriate and inappropriate prescriptions highlight the need for standardized pediatric guidelines, improved diagnostic support, and strengthened stewardship initiatives within primary care.

Patients with multiple traumas, particularly those with traumatic brain injury (TBI), are among the most challenging cases in intensive care medicine. Although early orotracheal intubation and invasive mechanical ventilation (IMV) are essential for airway protection and neurological treatment, they significantly increase the risk of lower respiratory tract infection (LRTI), including ventilator-associated pneumonia (VAP) and ventilator-associated tracheobronchitis (VAT). These complications are particularly prevalent among neurocritical patients due to the distinctive interaction between the brain, lungs and immune system. This narrative review examines the current evidence on the mechanisms underlying the brain–lung–immune axis; the diagnostic challenges in identifying respiratory infections in mechanically ventilated TBI patients; and optimal approaches to empirical or quasi-targeted antimicrobial therapy based on diagnostic algorithms and rapid molecular techniques. Severe TBI induces neurogenic inflammation, autonomic dysregulation, and immunosuppression, thereby increasing susceptibility to pulmonary infections. The ‘triple hit hypothesis’ best explains this cascade: sympathetic hyperactivity (first hit), iatrogenic ventilatory injury (second hit), and intestinal dysbiosis with systemic immune dysregulation (third hit). VAP diagnosis remains challenging due to the lack of universal criteria, the overlap with systemic inflammatory response syndrome, and the low specificity of radiological and clinical signs. VAT may represent an intermediate stage within a continuum of ventilator-associated infection. Recent evidence supports the selective use of nebulized antibiotics for VAT, advocating an individualized, locally adapted empirical approach to VAP treatment. Syndromic molecular panels can accelerate the identification of pathogens, enabling the earlier and more appropriate selection of antimicrobials and improving outcomes while preserving stewardship. Understanding the brain–lung–immune axis and improving diagnostic accuracy are essential to enhancing the treatment of respiratory infections in neurocritical care. Integrating clinical assessment, biomarkers and rapid microbiological testing enables timely, targeted therapy and reduces the misuse of antimicrobials. Full article

Background/Objectives: Ceftriaxone is widely used as empirical antimicrobial therapy (EAT) for urinary tract infections (UTIs). However, healthcare-associated urinary tract infections (HCA-UTIs) are often associated with inadequate EAT (IEAT). This study aims to evaluate the clinical impact of ceftriaxone as EAT in patients admitted to the hospital with community-onset HCA-UTIs in a setting with relatively high rates of antimicrobial resistance. Methods: A prospective observational study was conducted, comparing patients who received empirical treatment with ceftriaxone to those treated with other antibiotics. Results: A total of 235 cases were analyzed, 50.2% received ceftriaxone as EAT. The median age was 79 years, and 47.2% of patients were female. IEAT was significantly more frequent in the ceftriaxone group (36.4% vs. 17.1%, p = 0.001). Thirty-day mortality was 11.1%, with no significant difference between the ceftriaxone and non-ceftriaxone groups (11.9% vs. 10.3%, p = 0.752) but the use of antibiotics other than ceftriaxone was associated with a longer hospital stay (6 [4–8] vs. 5 [3–7] days, p = 0.037). The use of ceftriaxone as EAT was not associated with an increased risk of recurrence (16.1% vs. 15.4%, p = 0.709). Conclusions: In summary, empirical ceftriaxone use in patients with community-onset HCA-UTI was associated with a higher rate of inappropriate empirical therapy; however, it did not increase mortality or recurrence and was associated with a shorter hospital stay. These findings support the use of ceftriaxone as a potential option in selected patients without septic shock, while highlighting the importance of considering local resistance patterns and individual patient risk factors.

Background: Community-acquired pneumonia (CAP) remains one of the leading causes of infectious mortality worldwide. Variability in diagnosis and management can significantly influence outcomes. Objective: To assess the association between the implementation of a standardized hospital protocol and clinical outcomes in patients hospitalized for bacterial CAP and to identify factors associated with in-hospital and 30-day mortality. Methods: An ambispective before–after study was conducted at Hospital San Juan de Dios del Aljarafe (Seville, Spain), including a retrospective phase (2019) and a prospective intervention period (2022–2023). The intervention consisted of a standardized clinical protocol supported by training sessions and a 9-item checklist. Adults (≥18 years) with clinically and radiologically confirmed bacterial CAP were included. Mortality, length of stay, and empirical and targeted antibiotic adequacy were compared between periods. In the prospective cohort (n = 169), mortality-associated factors were analyzed using multivariate logistic regression. Results: A total of 1610 patients were analyzed: 634 in the pre-intervention period and 976 during the intervention period. Hospital mortality was lower during the intervention (11.3% [95% CI 9.3–13.2] vs. 16.6%; [95% CI 13.7–19.5] p = 0.002) with an absolute risk difference of 5.3%, corresponding to an approximate number needed to treat (NNT) of 19. Median length of stay decreased slightly (8.1 vs. 7.9 days; p < 0.001). In the prospective cohort, in-hospital mortality was 7.7% and 30-day mortality 16.6%. The therapeutic effort limitation (aOR 9.10, 95% CI 1.36–121.57; p = 0.021) and lower SaO2/FiO2 (aOR per unit 0.98, 95% CI 0.97–0.99; p < 0.001) were independently associated with in-hospital mortality. The ARDS (aOR 4.29, 95% CI 1.05–19.93; p = 0.043), lower SaO2/FiO2 (aOR 0.99 per unit, 95% CI 0.98–1.00; p = 0.005), older age (aOR 1.06 per year, 95% CI 1.02–1.12; p = 0.005), and lower Barthel Index (aOR 0.97 per point, 95% CI 0.94–0.99; p < 0.001) were associated with higher 30-day mortality. Conclusions: Implementation of a standardized CAP protocol was associated with lower mortality and high antibiotic adequacy in the intervention cohort. While causal inference is limited by the non-contemporaneous before–after design, these findings support the integration of structured, multidisciplinary, protocol-driven strategies—together with periodic audit and feedback cycles—to strengthen CAP management in community hospital settings.

Background and Objectives: Odontogenic sinusitis (ODS) is a particular type of sinus infection induced by dental infections or iatrogenic causes. Although not rare, it is often underrated and sometimes confused with other forms of chronic rhinosinusitis. The aim of this review was to summarize the main diagnostic aspects, microbiological profile, and current options in the therapeutic management of ODS. Materials and Methods: Recent studies and consensus statements from both dental and ENT fields were reviewed. The focus was on the ODS diagnostic criteria, the types and the timing of dental and endoscopic treatment approaches, and treatment combinations inducing the best outcomes in ODS. Results: ODS usually involves anaerobic bacteria such as Fusobacterium and Peptostreptococcus. Empirical antibiotics like amoxicillin or amoxicillin–clavulanate are most often used, but antibiotic therapy alone rarely cures the disease. Dental treatment is essential in ODS cases with oroantral fistulas, infected maxillary sinus bone grafts, or implants. However, in these clinical situations, concurrent one-stage dental and endoscopic sinus surgery (ESS) treatment seems to offer the highest success rate, close to 97%. Combined surgery significantly improved ODS treatment outcomes in terms of reduced reintervention rates and recurrence. There is still debate on how wide ESS should be in uncomplicated ODS, but many reports show that maxillary antrostomy alone can be sufficient. In apical periodontitis-related ODS, recurrence after primary ESS is uncommon in the short term. Conclusions: ODS management needs cooperation between ENT and dental specialists. Treating the dental underlying infection remains critical to prevent oral or systemic complications. Future research should better define diagnostic criteria, antibiotic use guidelines, and the best timing for combined surgery. New studies on microbiology, immunity, and artificial intelligence could help improve diagnosis and medical care of ODS patients. Full article

Background: Sepsis remains a major cause of morbidity and mortality in intensive care units (ICUs). Although various scoring systems and biomarkers have been studied, the prognostic significance of early dynamic changes in laboratory parameters remains unclear. This study aimed to investigate the prognostic value of 48 h changes in routinely monitored biomarkers for in-hospital mortality in septic patients. Methods: This retrospective, single-center study was conducted in the Anesthesiology and Reanimation ICU of a tertiary teaching hospital. A total of 174 adult patients (≥18 years) diagnosed with sepsis according to SEPSIS-3 criteria between January 2017 and December 2022 were included. Laboratory data were recorded at ICU admission and after 48 h. Patients who died within 48 h or had missing follow-up data were excluded. Receiver operating characteristic (ROC) analysis and logistic regression models were used to assess the prognostic performance of clinical and laboratory parameters. Results: The median age was 71 years, and 58% of patients were male. Comorbidities were present in 76% patients, and malignancy was associated with higher mortality (p = 0.012). The overall in-hospital mortality rate was 58.6%. Inappropriate empirical antibiotic therapy significantly increased mortality risk (p = 0.001). Non-survivors had higher baseline SOFA and APACHE II scores. At 48 h, mortality was associated with increased procalcitonin, lactate, and CRP/albumin ratio and greater albumin decline. ROC analysis identified procalcitonin ≤ 28% decrease, lactate > 23% increase, albumin > 7% decrease, and CRP/albumin ratio > 31% increase as optimal cutoffs. Multivariate analysis revealed SOFA score > 6, inappropriate antibiotic therapy, procalcitonin ≤ 28% decrease, lactate > 23% increase, and platelet > 37% decrease as independent mortality predictors. The change in albumin level was included in the model but was not statistically significant. Conclusions: Forty-eight–hour biomarker changes, particularly in lactate and platelet count, may provide complementary prognostic information to baseline SOFA scores and may support early risk stratification in sepsis. These findings should be considered exploratory and require confirmation in prospective multicenter studies before clinical implementation. Full article

Background: Biliary peritonitis is a severe intra-abdominal emergency with high mortality. Effective management requires source control and appropriate antimicrobial therapy. Methods: This review synthesizes recent literature (2016–2025), as well as established guidelines recommendations on the evolving microbiology and antimicrobial resistance patterns in biliary tract infections, as data on biliary peritonitis is scarce and relatively heterogeneous. Results: The microbiological landscape is stratified by patient history. Community-acquired infections are typically caused by Escherichia coli, Klebsiella pneumoniae, and Enterococcus spp. In contrast, healthcare-associated infections show a shift, with highly resistant pathogens such as Pseudomonas aeruginosa, and a tendency towards polymicrobial infections. The rise of multidrug-resistant (MDR) organisms, including extended-spectrum β-lactamase (ESBL)-producing Enterobacterales, Carbapenem-Resistant Enterobacterales (CRE), and Vancomycin-Resistant Enterococci (VRE), is a critical challenge limiting therapeutic options. Resistance patterns vary geographically, necessitating the use of local data. Conclusions: This review argues for a paradigm shift from severity-based guidelines to a dual-axis model incorporating resistance risk factors (prior healthcare exposure, previous biliary interventions, a history of MDR infections). We propose a risk-stratified approach to empiric antibiotic selection, emphasizing microbiological diagnostics for therapy de-escalation. Future research should focus on prospective studies, novel antibiotics, and rapid diagnostics. Full article

Background and Objectives: Helicobacter pylori (H. pylori) infection remains one of the most common chronic bacterial infections worldwide and is associated with a wide range of gastrointestinal disorders, including gastritis, peptic ulcer disease, and gastric cancer. Increasing rates of antibiotic resistance, particularly to clarithromycin and fluoroquinolones, represent a major therapeutic challenge. The objective of this study was to determine the prevalence of resistance-associated mutations in H. pylori-positive gastric biopsy samples from western Romania. Materials and Methods: We conducted a prospective study from January to December 2024, enrolling 138 patients undergoing gastroscopy. Biopsies were collected from the gastric antrum, and H. pylori infection was confirmed using the rapid urease test (RUT). Positive samples were further analyzed with the GenoType HelicoDR assay to detect mutations in the 23S rRNA gene (clarithromycin resistance) and gyrA gene (fluoroquinolone resistance). Clinical, demographic, and endoscopic data were also collected. Results:H. pylori infection was confirmed in 41.3% of the patients (57), of whom 63.2% (36) were treatment-naïve and 36.8% (21) had prior eradication therapy. Among treatment-naïve patients, clarithromycin resistance was identified in 19.4%, whereas previously treated patients showed a markedly higher resistance rate of 47.6% (p = 0.018). All clarithromycin-resistant cases carried the A2147G (23S MUT3) mutation. Fluoroquinolone resistance was present in 13.9% of naïve patients and increased to 23.8% in those with prior eradication therapy, with resistance linked to gyrA mutations at codons 87 (N87K) and 91 (D91 variants). Combined resistance to both antibiotics was observed only in a subset of previously treated patients. Conclusions: Primary resistance to clarithromycin in western Romania exceeds the 15% threshold defined by international guidelines, making clarithromycin-based triple therapy unsuitable as an empirical first-line option. The findings support the use of bismuth quadruple therapy as the preferred empirical regimen in this region. Also, molecular testing proved effective for rapid identification of resistance-associated mutations. Full article

Objective: This study aimed to evaluate the efficacy of empirical antibiotic therapy in treating chronic endometritis (CE) associated with abnormal uterine bleeding (AUB), infertility, or intrauterine lesions. Methods: The prospective cohort study involved 102 women undergoing outpatient hysteroscopy (OH), with immunohistochemical diagnosis of CE based on plasma cell density (PCD). Seventy-six of these women received empirical antibiotic therapy (ofloxacin and metronidazole), while 26 did not. A follow-up OH was conducted in the third cycle following the initial procedure. Results: Hysteroscopic polypectomy significantly reduced PCD regardless of antibiotic use (p = 0.009). In cases without focal lesions but exhibiting CE features, antibiotic therapy notably decreased PCD (p = 0.018). The incidence of certain histopathological features of CE, such as stromal edema and stromal cell compaction, was significantly lower in women treated with antibiotics (p = 0.014). Among intrauterine pathologies, endometrial polyps (p = 0.009) and cesarean scar defects (p = 0.011) significantly increased the risk of CE. Only spindled transformation of stromal cells with edema correlated significantly with elevated PCD (p = 0.022). Antibiotic therapy did not improve obstetric outcomes. Conclusions: Polypectomy alone reduced PCD without antibiotics, while antibiotic treatment significantly decreased PCD and resolved CE features in cases without focal lesions. Therefore, antibiotics may be prioritized for cases without focal lesions, whereas surgical intervention may be sufficient for CE associated with eligible pathologies. Full article

Background/Objectives: The incidence of late-onset sepsis (LOS) has increased with improved survival rates in premature infants. Blood culture, the diagnostic “gold standard”, requires at least 36–72 h for results, leading to empiric antibiotic use and potential resistance. MicroRNAs (miRNAs) have emerged as promising biomarkers for sepsis in adults, but their role in neonatal LOS remains unclear. The aim of this scoping review is to identify the miRNA expression profiles of bacterial LOS in neonates. Methods: A scoping review of the literature was performed between 1 November 2023 and 31 December 2024. Results: Twelve studies fulfilled our criteria and were included in the review. Despite the considerable heterogeneity among the studies, most focused on detecting and quantifying serum microRNAs using real-time PCR, while some examined correlations with other biomarkers, such as CRP. The few microRNAs identified as common across multiple studies showed similar patterns of regulation in LOS cases. Compared to controls (no LOS), neonates with LOS exhibited significant alterations in miRNA expression. More precisely, in LOS, miRNA-181a, miRNA-23b, miRNA-181b5p, miRNA-21-5p, miRNA-34a5p, miRNA-199a3p, miRNA-1184 and miRNA-1295p were downregulated, while miRNA-16, miRNA-146a, miRNA-101, miRNA-187, miRNA-21, miRNA-15a/16 and miRNA-455-5p were upregulated. Conclusions: Currently, there is limited data regarding miRNA expression in LOS. Many studies showed altered expression of specific miRNAs in septic neonates; however, these observations need further validation in larger cohorts and/or randomized controlled trials to confirm their diagnostic potential.

Acute chest syndrome (ACS) is a life-threatening complication of sickle cell disease (SCD) with complex infectious and non-infectious etiologies. Bacterial pathogens, including Streptococcus pneumoniae, Haemophilus influenzae, and atypical organisms such as Mycoplasma pneumoniae, play crucial roles in ACS pathogenesis, particularly in immunocompromised SCD patients with functional asplenia. Despite the importance of infectious triggers, regional data on pathogen identification rates and antimicrobial management strategies in ACS remain limited, especially from high-prevalence SCD regions. This study aimed to investigate the infectious etiologies, pathogen identification patterns, and antimicrobial management outcomes of ACS in adult SCD patients in Eastern Saudi Arabia. A five-year retrospective analysis was conducted on patients aged ≥14 years with SCD who were admitted with ACS to Dammam Medical Complex between 2018 and 2022. Comprehensive microbiological evaluation included blood cultures, sputum cultures, and atypical pathogen testing (Mycoplasma pneumoniae, Chlamydia pneumoniae). Data on antimicrobial regimens, pathogen identification rates, vaccination status against encapsulated bacteria, and clinical outcomes were systematically analyzed. Empirical antibiotic strategies and their effectiveness in this immunocompromised population were evaluated. A total of 60 adult SCD patients experiencing 80 episodes of ACS were included. Despite comprehensive microbiological workup, specific infectious pathogens were identified in only 8 (10.0%) episodes, highlighting the complex multifactorial etiology of ACS. Blood cultures yielded pathogens in 5 (6.3%) cases, sputum cultures in 4 (5.0%) cases, and Mycoplasma pneumoniae was identified in 3 (3.8%) episodes. All patients received empirical broad-spectrum antimicrobial therapy, with ceftriaxone and azithromycin combination being the most frequent regimen (76 cases, 95.0%), providing coverage for both typical and atypical bacterial pathogens. Antibiotic escalation was required in 16 (20.0%) episodes. Vaccination rates against Streptococcus pneumoniae were suboptimal at 30 (50.0%), representing a significant risk factor for invasive bacterial infections in this functionally asplenic population. The intensive care unit (ICU) admission rate was 15 (18.8%), and in-hospital mortality was 3 (3.8%), with infectious complications contributing to severe outcomes. In this cohort of SCD patients, ACS demonstrated low rates of specific pathogen identification despite systematic microbiological investigation, supporting the multifactorial infectious and non-infectious etiology of this syndrome. The predominant use of broad-spectrum antimicrobial therapy targeting both typical and atypical bacterial pathogens proved effective in this immunocompromised population. However, suboptimal vaccination rates against encapsulated bacteria represent a critical gap in infection prevention strategies. These findings emphasize the importance of empirical antimicrobial coverage for suspected bacterial pathogens in ACS management and highlight the urgent need for enhanced vaccination programs to prevent infectious complications in functionally asplenic SCD patients.

Background: Toxic shock syndrome (TSS) is a rare but potentially fatal condition most often caused by Staphylococcus aureus or Streptococcus pyogenes. However, other streptococcal species, including Streptococcus agalactiae (group B Streptococcus (GBS)), can also cause TSS, sometimes leading to severe complications, such as multiorgan failure. Case Description: We report the case of a 45-year-old woman who developed TSS associated with tampon use. She presented with fever, chills, hypotension, and leg pain, progressing rapidly to septic shock and multiorgan failure. Blood and urine cultures revealed S. agalactiae group B, while a gynecological examination identified Ureaplasma urealyticum and S. agalactiae. Imaging demonstrated bilateral pneumonic infiltrates and pleural effusion. The patient required intensive care, vasopressor support, and broad-spectrum antibiotic therapy, leading to full clinical recovery. Discussion: Despite advances in tampon design, menstrual TSS remains a significant clinical concern. Early symptoms may be nonspecific, but rapid progression highlights the need for timely recognition and intervention. Although S. agalactiae is an uncommon cause of TSS, it should be considered in relevant clinical scenarios. Prompt empirical antibiotic therapy, followed by targeted treatment based on culture results, along with supportive intensive care, is essential to improve outcomes. Conclusions: Menstrual TSS continues to pose a serious health risk. Physicians should maintain a high index of suspicion in tampon users presenting with fever, rash, and shock. Early diagnosis and rapid initiation of appropriate therapy are crucial to reducing morbidity and mortality. Full article

Background: The escalating burden of antimicrobial resistance (AMR) poses a critical threat to public health in Pakistan, with rates of high antibiotic consumption and limited standardized surveillance on AMR rates. Our study aimed to carry out a multicentric surveillance of AMR to generate regional antibiograms for Northern Punjab, Pakistan, to guide empirical antimicrobial therapy and stewardship efforts. Methods: A laboratory-based, retrospective cross-sectional study was conducted over a six-month period across three tertiary care hospitals. Socio-demographic, clinical, and microbiological data (including specimen type and antibiotic prescription rates) were collected from N = 485 patients with confirmed bacterial infections. Antimicrobial susceptibility testing was performed based on Clinical Laboratory Standards Institute (CLSI) recommendations. Statistical analyses were carried out using SPSS v.22.0. Results: In our study setting, Gram-positive bacteria were common causes (60.0%) of infections, with Staphylococcus aureus (12.2%) and Streptococcus pneumoniae (10.3%) being the most relevant. Among Gram-negative bacteria (40.0%), Escherichia coli (14.0%) and Pseudomonas aeruginosa (5.8%) were shown to be important pathogens. Overall, 25.0% of S. aureus isolates were methicillin-resistant (MRSA), while ~30% of E. coli showed resistance to third-generation cephalosporins (3GCs). Enterobacterales species had highly variable susceptibility rates (40–70%) for fluoroquinolones. Meropenem and vancomycin/linezolid retained high efficacy (>90%) against most Gram-negative and Gram-positive isolates, respectively. In all healthcare settings studied, ceftriaxone was the most frequently prescribed antibiotic. Conclusions: High levels of resistance against first-line antibiotics were noted in our setting of Northern Punjab, Pakistan, underscoring the critical need for robust antimicrobial stewardship programs, tailored to local institutional contexts, capabilities, and needs. The regional antibiogram developed based on our data may provide vital evidence for informing local empirical treatment guidelines, which need to be continuously updated. Full article

Urinary tract infections (UTIs) are a global health concern, with over 150 million cases annually, primarily caused by Escherichia coli. Due to anatomical differences, females, especially children and postmenopausal women, are four times more susceptible. Crucially, E. coli has developed widespread antimicrobial resistance (AMR), including resistance to broad-spectrum agents and the emergence of Extended-Spectrum Beta-Lactamase (ESBL)-producing strains. This retrospective study analyzed hospital records from 95 female patients with positive urine cultures at Siblin Governmental Hospital in 2024. Patients were stratified into three age categories: children (≤18 years), adults (18–64 years) and elderly patients (>64 years). Statistical analysis using SPSS focused on descriptive resistance patterns and differences across age groups. Overall, cephalothin (85.7%) and cefaclor (78.49%) exhibited the highest resistance rates. Conversely, tigecycline (97.22%) and ertapenem (91.67%) showed the highest susceptibility. Resistance patterns varied significantly by age. For instance, elderly patients showed high resistance to agents like Augmentin (52.5%) and cefixime (66.1%), while the pediatric group (≤18 years) displayed exceptionally high resistance to cefixime (90.0%). E. coli isolates show high resistance to conventionally used antibiotics, complicating UTI treatment. These findings highlight the need for continuous local surveillance, particularly focusing on third-generation cephalosporins and beta-lactamase production. Ultimately, age is a critical factor that must be considered when determining empirical antibiotic therapy for UTIs. Full article
