Correlation Between the Suitability of Empirical and Definitive Therapies According to Culture Results with the Clinical Outcomes of Patients with Bacteremia Due to Carbapenem- Resistant Acinetobacter baumannii (CRAB) at Dr. Soetomo Tertiary Referral Hospital

Carbapenem administration is an important therapy for nosocomial infections due to MDRO, especially Acinetobacter baumannii. The global increase in carbapenem-resistant A. baumannii (CRAB) that causes this pathogen has significantly threatened public health due to the lack of adequate treatment options due to the very few currently available antimicrobial agents that actively fight CRAB. Antimicrobial resistance is a major negative impact of inappropriate antimicrobial prescribing. Ineffective empiric treatment (initial antibiotic regimen not sensitive to identified pathogens based on in vitro sensitivity test results) is associated with a higher rate of deaths compared to effective empiric treatment. In this study, we analyzed the correlation between the suitability of empiric and definitive antibiotics and the clinical outcomes of patients with bacteremia due to CRAB treated in the inpatient ward of Dr. Soetomo Tertiary Referral Hospital, Surabaya. There were 227 isolates of bacteremia due to CRAB, consisting of 156 carbapenem-resistant A. baumanni and 71 carbapenem-sensitive A. baumannii. There were 88 isolates that met the inclusion and exclusion criteria, and all of them were resistant to ceftriaxone, cefepime, and ciprofloxacin. A total of 29.5% of the isolates were sensitive to cotrimoxazole, 3.4% of the isolates were sensitive to tigecycline, and 2.3% of the isolates were sensitive to amikacin, levofloxacin, and cefoperazone sulbactam. Adequate empirical antibiotics and definitive antibiotics (sensitive based on culture sensitivity test) amounted to 12.5% and 27.3%, respectively. There is no significant correlation between the suitability of empiric and definitive therapies with the patients' clinical outcomes (death and length of stay).Copyright © 2022 Phcogj.Com.

Sars cov-2 infection in a neonate in ghana: A case report

Backgrounds: The clinical and socioeconomic effects of COVID-19 are still being felt through-out the world. The disease affects people of all age groups, but it is known to have a milder clinical course in children including neonates. There is paucity of data from Sub-Saharan Africa on neonatal COVID-19 infection, and no such case has been reported in the literature in Ghana. Case presentation: This study presented a case report of a neonate who was found to be positive for COVID-19 infection after presenting symptoms such as respiratory distress, rhinorrhoea, and cough. This neonate was managed with in-hospital standard protocol for sepsis with a focus on pneumonia. Conclusion(s): The national guidelines on COVID-19 management were used for the neonate who was recovered and discharged.Copyright © 2021, TMU Press.

Basophil activation test in clinical and laboratory investigation of patients with beta-lactam allergy

Background: Drug hypersensitivity reactions (DHRs) of the immediate type are diagnosed in approximately 1-2% per 100 thousand people. During the COVID-19 pandemic, the use of antibiotics increased, and cases of immediate reactions to these drugs became more frequent. However, due to the lack of medical centers which have the necessary conditions for carrying out provocation tests, the use of in vitro diagnostic methods for hypersensitivity reactions to antibiotics is becoming even more relevant during the pandemic. Flow CAST Basophil Activation Test (BAT) Flow Cytometry can be used for the in vitro detection of immediate type allergic reactions and hypersensitivities to suspected allergens in patients at risk for DHRs. The purpose is to study the possibility of diagnosing hypersensitivity reactions to antibiotics using BAT to antibiotics. Method(s): The Patient Questionnaire Card and the Patient Review Card were used to survey 32 (8.7%) individuals (f -56.3%, m -43.7%) who met the inclusion criteria (the presence of hypersensitivity reactions to beta-lactam antibiotics during the last 3 years). We used Flow CAST to identify the DHRs to beta-lactam antibiotics (Ceftriaxone (conc. 4 mg/ml);Cefuroxime (conc. 2.5 mg/ml);Amoxicillinum (conc. 2.5 mg/ml) from CAST Allergens for CASTFlow CAST) BUHLMANN LABORATORIES AG, Switzerland) in whole blood. Flow cytometric acquisition was performed on a flow cytometer BD FacsCalibur (USA), and 300 basophilic cells were analyzed. Result(s): The most common clinical manifestations included acute urticaria + angioedema (40.6%), generalized urticaria (28.1%), anaphylactic shock (21.9%), bronchospasm (9.4%). The percentage of patients diagnosed with an immediate reaction based on the time of its occurrence was 62.5%, whereas the percentage of patients diagnosed with an immediate reaction based on the clinical manifestations was 81.25%, which was confirmed by positive BAT results (p > 0.05). 68.75% of people with clinical manifestations of reactions to one antibiotic (ceftriaxone or amoxicillin) showed increased values on the BAT test to other beta antibiotics, which may indicate the presence of cross-reactivity between these groups of drugs. Conclusion(s): Diagnostics of immediate hypersensitivity reactions to antibiotics based on in vitro BAT is a highly accurate method. However, in cases of possible cross-reactivity between antibiotics and in cases of delayed reactions, in-depth studies are required.

Study of Prescription Pattern of Covid-19 Intensive Care Unit Patients in a Tertiary Care Hospital

COVID- 19 was the most challenging public health problem worldwide for better part of 2 years (2019 - 2021). Although several of the medication have not demonstrated promising benefits in the majority of research, they are nonetheless utilized. The purpose of this study was to compare and contrast the hospital pharmaceutical care of COVID-19 patients by sex, age group, and with regards to oxygen consumption classifying and grouping them with comorbidities seen and auxiliary medication given . Hospital based retrospective observational study was conducted among 123 patients with antigen positive Reverse Transcriptase Polymerase Chain Reaction confirmed COVID- 19 infection admitted in the ICU for 24 hours prior. As the age increased the chance for ICU admission also increased. The most affected age group was above 50 years of age. The total number of patients requiring oxygen was 100% in COVID- 19 ICU patients. Some of the most common comorbidities were heart disease (18%) followed by Diabetes Mellitus (15%) and Hypertension (15 %). Only 48 % of patients received antivirals. Remdesivir which was the mainstay antiviral was given (41%). Amoxicillin and clavulanate combination (Augmentin 625 mg) was the most commonly prescribed antibiotic (27%).The antipyretic of choice was paracetamol which was given to 100% of patients. Almost all patients (78%) were given enoxaparin sodium as the anticoagulant of choice. Regardless of equivocal results, multivitamins and supplements were recommended to all patients. All prescription guidelines as given by ICMR for COVID- 19 ICU patients were followed with the exception of the extensive antimicrobial use.Copyright © 2022 Wolters Kluwer Medknow Publications.

Adjunctive azithromycin prophylaxis protects women from uterine cesarean scar defect: A randomized controlled trial.

INTRODUCTION: Cesarean scar defect (CSD) is a long-term outcome of cesarean section (CS) and associated with numerous gynecological and obstetric problems. Previous studies indicate that infection may be a risk factor for CSD. Adjunctive azithromycin was shown to reduce the risk of postoperative infection in patients undergoing non-elective primary cesarean delivery in labor or after the rupture of membranes compared with standard antibiotic prophylaxis. This study investigated the protective effect of adjunctive azithromycin in combination with single-dose cephalosporin against CSD in women undergoing non-elective cesarean delivery. MATERIAL AND METHODS: A randomized, double-blind, controlled clinical trial was conducted in a University hospital in Shanghai, China. A total of 242 women who underwent their first non-elective CS were randomly assigned to receive 1500 mg cefuroxime sodium plus 500 mg intravenous azithromycin (n = 121; experimental group) or 1500 mg cefuroxime sodium plus a placebo (n = 121; placebo group). The primary outcome was CSD prevalence, as determined by transvaginal ultrasound and saline infusion sonohysterography within 6 months of delivery. Secondary outcomes were changes in infectious indicators (eg hypersensitive C-reactive protein and procalcitonin), postoperative morbidity, and use of postoperative antibiotics. We also examined the operative procedure, pathogenic microorganism cultures, and fetal outcomes. Outcomes were compared between groups with the chi-squared test, Fisher's exact test, or Student's t test. RESULTS: Between May 2018 and May 2021, 121 women were randomized to each arm. Because the sonographic follow up was disrupted by the coronavirus disease 2019 pandemic and strict management policies, we merged the follow-up time points (6 weeks and 6 months) into a single time period (6 weeks to 6 months); 104 and 108 women in the experimental and placebo groups, respectively, completed the first sonographic follow up. CSD was diagnosed by sonography in 34/104 (32.7%) and 50/108 (46.3%) patients in the experimental and placebo groups, respectively (relative risk 0.71, 95% confidence interval 0.50-0.99; p = 0.043). Characteristics of CSD and short-term infection outcomes did not differ between groups. CONCLUSIONS: A single dose of intravenous 500 mg azithromycin adjunctive to single-dose cefuroxime prophylaxis significantly reduced the incidence of CSD in women undergoing non-elective CS.

Effectiveness of beta-lactam allergy label withdrawal

Background: In our setting,it is common for patients to be “labelled” as allergic in the presence of doubtful clinical signs of intolerance or allergic reaction. Moreover,it is not uncommon that patients who have been ruled out allergy to beta-lactam antibiotics (BL-ATB) continue to be mislabelled allergologically in the electronic medical records.Unfortunately,this mistake means that they are sometimes deprived of the first therapeutic option. Objective: The main objective of the study was to assess the correct labelling of patients(p) from an allergological point of view in Primary Care,in the Emergency Department and in visits to other specialists. The secondary objectives were:to determine the percentage of patients who received BL-ATB, the reason for the prescription and the drugs used. Method: Prospective review of the medical records of 92 patients who have been ruled out allergy to BL-ATB in our department during the months of August 1st,2019, to March 31st,2020.All patients have been followed for at least 12 months.Data were collected by reviewing the electronic medical records. Results: Of the 92 patients, only 64%(54p) were well identified in primary care. Only 36%(33p) had attended the Emergency Department,of which 76%(25p) were correctly identified and the remaining 24%(8p) were not. 38%(35p) were visited by an specialist, in a total of 42 visits(v). In 74% of the visits (31v) the patients were correctly identified and in the remaining 26% they were not.Table 1 summarises the number of visits to each specialist and the correct or incorrect allergological identification. Only 17%(16p) received BL-ATB, on a total of 20 occasions.Urinary tract infections were the most frequent reason for prescribing BL-ATB (4p), followed by H.Pilory infection(3p),skin infections(3p),respiratory infections(3p),sepsis (2p),acute otitis media(1p),pharyngitis(1p),sinusit is(1p),oral infections(1p) and bone fractures(1p). Amoxicillin was the most commonly used drug(8p),followed by Amoxicillin/Clavulanic acid(5p),Cefuroxime(2p),Meropenem(2p),Cef triaxone (1p) and Piperacillin/Tazobactam(1p). Conclusion: Despite the efforts being made by Allergology services to correctly label patients with HS to BL, a high percentage remain misidentified. In relation to the consumption of BL-ATB, we believe that the data are underestimated,given that during the months of follow-up of the study (year 2020) the use of masks and hand washing recommended by the COVID-19 pandemic have reduced both infections and access to health care.

Repurposing cefuroxime for treatment of COVID-19: a scoping review of in silico studies.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of Coronavirus disease 19 (COVID-19), is a novel human Coronavirus that is responsible for about 300,000 deaths worldwide. To date, there is no confirmed treatment or vaccine prevention strategy against COVID-19. Due to the urgent need for effective treatment, drug repurposing is regarded as the immediate option. Potential drugs can often be identified via in silico drug screening experiments. Consequently, there has been an explosion of in silico experiments to find drug candidates or investigate anecdotal claims. One drug with several anecdotal accounts of benefit is Cefuroxime. The aim of this study was to identify and summarize in silico evidence for possible activity of Cefuroxime against SARS-CoV-2.To this end, we performed a scoping review of literature of in silico drug repurposing experiments for SARS-CoV-2 using PRISMA-ScR. We searched Medline, Embase, Scopus, Web of Knowledge, and Google Scholar for original studies published between 1st Feb, 2020 and 15th May, 2020 that screened drug libraries, and identified Cefuroxime as a top-ranked potential inhibitor drug against SARS-CoV-2 proteins. Six studies were identified. These studies reported Cefuroxime as a potential inhibitor of 3 key SARS-CoV-2 proteins; main protease, RNA dependent RNA polymerase, and ACE2-Spike complex. We provided a summary of the methodology and findings of the identified studies. Our scoping review identified significant in silico evidence that Cefuroxime may be a potential multi-target inhibitor of SARS-CoV-2. Further in vitro and in vivo studies are required to evaluate the potential of Cefuroxime for COVID-19.Communicated by Ramaswamy H. Sarma.

Isoflavonoid-Antibiotic Thin Films Fabricated by MAPLE with Improved Resistance to Microbial Colonization.

Staphylococcus aureus (Gram-positive) and Pseudomonas aeruginosa (Gram-negative) bacteria represent major infectious threats in the hospital environment due to their wide distribution, opportunistic behavior, and increasing antibiotic resistance. This study reports on the deposition of polyvinylpyrrolidone/antibiotic/isoflavonoid thin films by the matrix-assisted pulsed laser evaporation (MAPLE) method as anti-adhesion barrier coatings, on biomedical surfaces for improved resistance to microbial colonization. The thin films were characterized by Fourier transform infrared spectroscopy, infrared microscopy, and scanning electron microscopy. In vitro biological assay tests were performed to evaluate the influence of the thin films on the development of biofilms formed by Gram-positive and Gram-negative bacterial strains. In vitro biocompatibility tests were assessed on human endothelial cells examined for up to five days of incubation, via qualitative and quantitative methods. The results of this study revealed that the laser-fabricated coatings are biocompatible and resistant to microbial colonization and biofilm formation, making them successful candidates for biomedical devices and contact surfaces that would otherwise be amenable to contact transmission.
