Ceftriaxone resistance among patients at GAMBY teaching general hospital

A Four-Year Trend of Ceftriaxone Resistance and Associated Risk Factors Among Different Clinical Samples in Wad Medani, Sudan: A Cross-Sectional Retrospective Study

Introduction In sub-Saharan Africa, including Sudan, there is commonly no local data on the bacterial profile or antibiotic resistance pattern. Therefore, to bridge these gaps, this study aimed to evaluate ceftriaxone resistance patterns and associated risk factors among different clinical samples. Methods This study was a laboratory-based, retrospective, cross-sectional study. All clinical specimens were obtained from patients at Wad Medani and examined at the Pathology Center for Diagnosis and Research, Faculty of Medicine, University of Gezira, Sudan, from January 2020 to October 2023. Results Overall, 1784 specimens exhibited bacterial growth over four years. Of these, 1260 (70.6%) were females. Approximately one-third of the 588 (33%) studied patients were aged 30 to 44 years. Of the studied samples, 1108 (62.1%) were urine, and 465 (26.1%) were wound swabs. Staphylococcus aureus (697, 39.1%) and Escherichia coli (656, 36.8%) were the most frequently encountered bacteria. Generally, ceftriaxone resistance has been evaluated in 150 positive culture samples. The overall ceftriaxone resistance rate was 106 (70.7%). The greatest proportion of ceftriaxone resistance was observed in 4/4 (100%) of Klebsiella spp. and 66/82 (80.5%) of E. coli strains. The type of isolate (95% Cl, p-value; 0.006) and type of bacterial stain (95% Cl, p-value 0.013) have been significantly associated with ceftriaxone resistance, in which Gram-negative bacteria had a greater resistance rate of 98/132 (74.2%) than Gram-positive bacteria 8/18 (44.4%). Conclusions This study revealed a high rate of ceftriaxone resistance. The most resistant bacteria were Klebsiella spp. and E. coli. The type of isolate and bacterial stain were significantly associated with ceftriaxone resistance. Therefore, hospitals should immediately and significantly modify their antibiotic prescription policy to give doctors a consistent strategy for the rational, safe, and effective administration of antibiotics.

Developing Systems of Emergency and Inpatient Neurologic Care in Resource-Limited Settings

Neurologic diseases represent a significant global health challenge, leading to disability and mortality worldwide. Healthcare systems in low- and middle-income countries are disproportionally affected. In these resource-limited settings, numerous barriers hinder the effective delivery of emergency and inpatient neurologic care, including shortages of trained personnel, limited access to diagnostics and essential medications, inadequate facilities, and absence of rehabilitation services. Disparities in the neurology workforce, limited access to neuroimaging, and availability of acute interventions further exacerbate the problem. This article explores strategies to enhance global capacity for inpatient neurologic care, emphasizing the importance of workforce development, context-specific protocols, telehealth solutions, advocacy efforts, and collaborations.

Antimicrobial Resistance Patterns and Risk Factors Associated with ESBL-Producing and MDR Escherichia coli in Hospital and Environmental Settings in Lusaka, Zambia: Implications for One Health, Antimicrobial Stewardship and Surveillance Systems

Antimicrobial resistance (AMR) is a public health problem threatening human, animal, and environmental safety. This study assessed the AMR profiles and risk factors associated with Escherichia coli in hospital and environmental settings in Lusaka, Zambia. This cross-sectional study was conducted from April 2022 to August 2022 using 980 samples collected from clinical and environmental settings. Antimicrobial susceptibility testing was conducted using BD PhoenixTM 100. The data were analysed using SPSS version 26.0. Of the 980 samples, 51% were from environmental sources. Overall, 64.5% of the samples tested positive for E. coli, of which 52.5% were from clinical sources. Additionally, 31.8% were ESBL, of which 70.1% were clinical isolates. Of the 632 isolates, 48.3% were MDR. Most clinical isolates were resistant to ampicillin (83.4%), sulfamethoxazole/trimethoprim (73.8%), and ciprofloxacin (65.7%) while all environmental isolates were resistant to sulfamethoxazole/trimethoprim (100%) and some were resistant to levofloxacin (30.6%). The drivers of MDR in the tested isolates included pus (AOR = 4.6, CI: 1.9-11.3), male sex (AOR = 2.1, CI: 1.2-3.9), and water (AOR = 2.6, CI: 1.2-5.8). This study found that E. coli isolates were resistant to common antibiotics used in humans. The presence of MDR isolates is a public health concern and calls for vigorous infection prevention measures and surveillance to reduce AMR and its burdens.

Rational Use of Ceftriaxone in Necrotizing Fasciitis and Mortality Associated with Bloodstream Infection and Hemorrhagic Bullous Lesions

Necrotizing fasciitis (NF) is an uncommon life-threatening necrotizing skin and soft tissue infection. The formation of hemorrhagic bullae is a special skin sign of NF. The purposes of this study were to investigate the incidence of hemorrhagic bullae formation and bacteremia associated with different organisms, to appraise the appropriate use of ceftriaxone, and to compare the clinical and laboratory risk indicators of NF patients with Gram-positive and Gram-negative infections on the initial examination. Methods: From March 2018 to December 2020, there were seventy-four NF patients with positive monomicrobial bacterial cultures enrolled based on surgical confirmation, and were categorized into two groups: the Gram-positive group and the Gram-negative group. Ceftriaxone susceptibility tests were carried out using the standard disk diffusion technique. Data, such as demographics, clinical outcomes, microbiological results, presentations of hemorrhagic bullae, and laboratory findings, were compared among these two groups. Results: The Gram-negative group included 52 patients, of whom 6 patients died, resulting in a mortality rate of 11.5%. The Gram-positive group included 22 patients and none died. Patients with bacteremia, hemorrhagic bullae, shock, fever, higher segmented forms and banded forms, and lower platelet counts constituted higher proportions in the Gram-negative group than in the Gram-positive group. The multivariate analysis identified six variables for the differentiation of Gram-negative and Gram-positive NF: the presentation of bacteremia, hemorrhagic bullae, shock at first consultation, fever with body temperature > 38.5 °C, band forms > 0%, and segmented forms ≦ 74%. A total of 66 isolates (89.2%) was susceptible to ceftriaxone. Conclusions: Gram-negative NF patients were significantly associated with hemorrhagic bullae presentation, blood stream infection, and mortality. Physicians should be alert to NF patients with the appearance of bacteremia, shock, fever, higher WBC banded and segmented forms, and lower platelet counts at the emergency department, with patients revealed to more likely have Gram-negative infections. Ceftriaxone with/without other appropriate antibiotics under the supervision of infectious doctors appeared to be clinically effective for the treatment of NF and blood stream infections.
