ABSTRACT
Background: Since patients admitted to the intensive care unit have a compromised im-mune system and are more prone to infection than other patients, timely diagnosis and treatment of corneal ulcers among this group of patients can prevent vision loss. Therefore, it is necessary to treat eye infections and corneal ulcers promptly and economize prohibitive costs. Objective(s): Appropriate treatment with the most effective antibiotic before the answer is available to prevent corneal ulcer complications and blindness. Method(s): This study was conducted from November 2019 to November 2020 and after approval by the ethics committee of Hamedan University of Medical Sciences with the code of ethics: IR.UMSHA.REC.1398.716. First, the corneal secretions of 121 patients admitted to the intensive care unit of Sina Hospital are prepared by an ophthalmologist (after anesthetizing the cornea with tetra-caine drops and sterile swabs) and culture in four growth mediums (blood agar, chocolate agar, thio-glycolate, and EMB). Microbial cultures are examined after 48 hours and a fungal culture is examined one week later. Disc diffusions are placed in positive microbial cultures. Antibiotic susceptibility or resistance of the antibiogram was recorded. Other demographic data, including patients' age and sex, are extracted from ICU files. Also, test results and patient identifications are recorded in a checklist designed for this purpose. Result(s): Of all the antibiotics used against common bacteria, vancomycin (84%), colistin (80.43%), cefazolin (80%), and levofloxacin (60%) had the highest sensitivity and gentamicin (93.75%), ceftazidime (86.42%) Erythromycin (85%) had the highest resistance against isolated bacteria. Conclusion(s): The data obtained from this study showed that the most common microorganisms in the age group under the age of 30 years were Acinetobacter Baumannii, in the group of 30-60 years old was Klebsiella pneumonia, and age group over 61 years old was Staphylococcus aureus, and the most sensitive antibiotics in the age group under 30 years were vancomycin and levofloxacin and the age group30-60 were colistin and vancomycin and in the age group over 61 years were vancomycin and cefazolin.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
Burkholderia pseudomallei is soil saprophytic Gram-negative bacilli that cause a fatal disease called melioidosis. Melioidosis is capable of causing cutaneous infection and systemic infections in the respiratory tract, cardiovascular, gastrointestinal, urinary, skin and soft tissue, and musculoskeletal and central nervous systems. Here, we report rare forms of pulmonary, cerebral, and splenic abscess case series of melioidosis caused by B. pseudomallei. Imported cases have been reported among tourists, immigrants, and soldiers who returned from endemic areas. The acquisition of infection is through percutaneous, inhalation, and ingestion of contaminated water;person-to-person transmission is very rare. Melioidosis cases are primarily found in the rainfall season and are usually associated with risk factors such as diabetes, alcoholism, and chronic renal diseases. However, 20-26% of cases were not associated with predisposing conditions. The identification is based on colony morphology, Gram stain, antibiotic susceptibility testing, and other supportive automated and molecular assays when we suspect B. pseudomallei. There are two phases, the intensive and eradication phases, in managing melioidosis. In the intensive phase, ceftazidime for 2 weeks showed efficacy in almost 50% of cases, and the eradication phase treatment with co-trimoxazole and doxycycline or amoxicillin/clavulanic acid for 3-6 months showed an excellent response. The improper clinical diagnosis and management of B. pseudomallei can lead to complications. Hence, early diagnosis with microbiological approaches such as culture, biochemical reactions, or automated systems available and antimicrobial sensitivity testing will cure the patient quickly without mortality.Copyright © 2023 The Authors.
ABSTRACT
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.
ABSTRACT
Objectives: A 14-year-old female patient presents with marked haemorrhagic, adherent crusting of the upper and lower lip and enoral vesicles and erosions. Two weeks before, she had suffered from a respiratory tract infection. She did not take antibiotics but ibuprofen. One week later, she described a swelling and crusting of the upper and lower lips. Urogenital mucosa was also erosive. There was no ocular involvement. Another week later, cocard-like single lesions with partly central blister formation developed. A flaccid blister of 15 mm in diameter was detected in the left ear helix. In total, there was a limited cutaneous involvement of <10% BSA. The girl was admitted to the paediatric clinic. Method(s): Due to mucocutaneous eruptions, bullous lesions and multimucosal involvement, we assumed a Steven-Johnson syndrome or reactive infectious mucocutaneous eruption (RIME). Intravenous rehydration and prophylactic administration of cefotaxime and aciclovir were given. She was balanced and given analgesia with novalgin. The recent increased intake of ibuprofen was discontinued. Local therapy included mometasone cream and serasept dressings. During the inpatient stay, the general condition stabilised and the skin efflorescence's showed a clear regression. Result(s): The microbiological smears for COVID-19, HSV, VZV, mycoplasma, and chlamydia were negative. Discussion(s): As adult classifications for blistering severe cutaneous adverse reactions are limited applicable in children, Ramien et al. proposed revised paediatric-focused clinical criteria 2021. They leave traditional definitions of EEM, SJS and TEN. But they distinguish erythema multiforme (EM) for classic targets with/without mucosal involvement, RIME for cases with mucosal predominance and a respiratory infection trigger, and drug-induced epidermal necrolysis (DEN) for cases caused by medications. (Ramien BJD 2021) There are no current guidelines for RIME therapy. A reasonable management approach includes symptomatic therapy, treatment of identifiable infectious triggers (if possible), consulting urologists, ophthalmologists and gynaecologists (if necessary), immunosuppression, and psychological support. (Ramien ClinExpDermatol 2021).
ABSTRACT
Antibiotics play an essential role in antimicrobial therapy. Among all the medications in children, the most commonly prescribed therapy is antibiotics and is currently the indispensable means to cure transmissible diseases. Several categories of antibiotics have been introduced into clinical practice to treat microbial infections. Reducing the unnecessary use of antibiotics is a global need and priority. This article aims to provide better knowledge and understanding of the impact of the early use of antibiotics. This article highlights the proper use of antibiotics in chil-dren, detailing how early and inappropriate use of antibiotics affect the gut microbiome during normal body development and consequently affect the metabolism due to diabetes mellitus, obe-sity, and recurrence of infections, such as UTI. Several new antibiotics in their development stage, newly marketed antibiotics, and some recalled and withdrawn from the market are also briefly discussed in this article. This study will help future researchers in exploring the latest information about antibiotics used in paediatrics.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
Objectives: The COVID-19 pandemic has had a major impact on the healthcare system, which has been forced to manage large num-bers of patients, including those with respiratory insufficiency and in need of oxygen therapy. Due to concerns about bacterial co-in-fection, antibiotic therapy was administered to many patients. The aim of the present study was to compare antimicrobial resistance in intensive care patients in the pre-pandemic and pandemic periods. Material(s) and Method(s): Patients hospitalized at the Department of Anesthesiology, Resuscitation and Intensive Care Medicine of the University Hospital Olomouc in the pre-COVID-19 period (2018-2019) and during the pandemic (2020-2021) were enrolled in the stu-dy. Clinical samples from the lower respiratory tract were routinely collected twice a week, with one strain of a given species first isolated from each patient being included in the study. Result(s): While several bacterial species (Escherichia coli, Proteus mirabilis and Haemophilus influenzae) were found to occur less fre-quently, an increased occurrence was documented for Enterococcus faecium, Serratia marcescens and Klebsiella variicola. Overall, ho-wever, it can be concluded that there was no major change in the frequency of bacterial pathogens isolated from the lower respiratory tract during the COVID-19 period. Similarly, with only a few exceptions, antimicrobial resistance did not change significantly. More significant increases in resistance to piperacillin/tazobactam, cefotaxime, ciprofloxacin and gentamicin have been demonstrated for Serratia marcescens. However, a decrease in the resistance of Pseudomonas aeruginosa and Burkholderia cepacia complex to mero-penem was also observed. Conclusion(s): There was no significant change in the frequency of bacterial pathogens and their resistance to antibiotics during the COVID-19 pandemic. However, there was an increase or decrease in the percentage of some species and in their resistance.Copyright © 2022, Trios spol. s.r.o.. All rights reserved.
ABSTRACT
Plasmid-mediated quinolone resistance (PMQR) genes confer low resistance to Fluoroquinolones (FQs). This study aims to detect five PMQR genes among FQs-resistant Klebsiella pneumoniae isolated from various clinical specimens. Out of 120 K. pneumoniae isolates, 68 FQs-resistance K. pneumoniae were included in a molecular study. Standard microbiological tests were used for identification and antimicrobial susceptibility. For the detection of PMQR genes, conventional polymerase chain reaction was used. A molecular study revealed that (73.5%) of samples harbored PMQR genes, and among them, 58% were co-carriages of PMQR gene variants. Aac (6')-Ib-cr gene was predominant (47.1%) among samples, and qepA had the lowest percentage (11.8%), qnr genes were (32.4%) (29.4%) (20.6%) qnrS, qnrB, and qnrA respectively. Overall, high percentages of PMQR genes were detected, and almost all of samples were phenotypically resistant to ciprofloxacin. As well, there was a significant statistical relationship between phenotypically ESBL-producers and qnrB and qepA genes.Copyright © Abdulkareem MM et al.

ABSTRACT
Case report Background: Neurological adverse effects (NAE) as headache and dizziness are commonly reported with COVID-19 vaccines but are transient and self-limited. However, few serious NAE have been recently described which can be fatal. Here we report two rare cases of encephalitis related to COVID-19vaccination BNT162b2 (Pfizer) and mRNA-1273 (Moderna) and the inherent challenges in their diagnosis. Method(s): We report two cases of acute encephalitis notified to the department of pharmacovigilance in the University Hospital of Monastir Results: Case n'1: Three weeks after receiving her first dose of mRNA-1273, a 35-year- old female, with a medical history of hypothyroidism and eczema was admitted to the intensive care unit as she had confusion and a febrile tonic-clonic seizure complicated with a status epilepticus and dysautonomia. CSF investigations were nonspecific, and the MRI head did not detect any abnormality. Common causes were excluded by an extensive workup (neoplastic, neuro-vascular, autoimmune and infectious causes). She received cefotaxime and acyclovir without any recovery. However, a spectacular recovery was noticed when receiving methylprednisolone. Case n'2: Three days after receiving her first dose of BNT162b2, a-40- year- old female, with a medical history of rheumatoid arthritis was admitted to the medical care unit as she had experienced a three-day history of headache, memory disturbance, severe cognitive disorders and 4 febrile tonic-clonic seizures. MRI head showed signs of bitemporal encephalitis and CSF investigations was with no findings. Extensive laboratory studies ran out alternative causes as neoplastic, autoimmune and infectious diseases. A twenty-one- day acyclovir regimen was administrated with no recovery. As the cognitive deficit is getting more severe, she got intravenous immunoglobulin therapy with a spectacular improvement. Conclusion(s): Based on the Naranjo Algorithm, this adverse NAR can be possibly (score = 6) induced by COVID-19 vaccines. The dramatic improvement after receiving either corticoids or immunoglobulin therapy supports an immune-mediated mechanism behind this acute presentation. Cases of acute encephalitis secondary to H1N1 influenza and poliomyelitis vaccines have been previously reported but those related to COVID-19 vaccines are still not yet elucidated due to the unproven causality. Further prospective studies are needed to evaluate the causal association between vaccine and NAE occurring vaccination.
ABSTRACT
Antibody deficiencies constitute the majority of primary immunodeficiencies in adults. These patients have a well-established increased risk of bacterial infections but there is a lack of knowledge regarding the relative risks upon contracting COVID-19. In this monocentric study the disease course of COVID-19 in 1 patient with Good's syndrome and in 13 patients with common variable immunodeficiency (CVID) is described. The severity of disease ranged from very mild to severe. Several patients required hospitalization and immunomodulatory treatment but all survived. Although viral infections are not a typical feature of humoral immunodeficiencies we recommend that vigilance is increased in the management of patients with Good's syndrome and CVID during the COVID-19 pandemic.Copyright © 2021
ABSTRACT
Objective: The impact of COVID-19 on the number and antibiogram profile of Salmonella was studied between January 2018 and December 2021. The present time period included years before the COVID-19 pandemic, which are 2018 and 2019, and during the pandemic, which are 2020 and 2021. Material(s) and Method(s): Salmonella infections were classified into eight distinct serogroups using slide agglutination with specific antisera (A, B, C, D, E, F, G, and I). The susceptibility to antimicrobial agents were evaluated by the standard disk diffusion method. Result(s): Four hundred fifty-one isolates were detected (139 in 2018, 119 in 2019, 102 in 2021, and 91 in 2021). Salmonella infection decreased by 25.2% from 258 isolates in 2018 and 2019 to 193 in 2020 and 2021. When comparing Salmonella infections in different age groups (0 to 10, 11 to 20, 21 to 30, 31 to 40, 41 to 50, 51 to 60, 61 to 70, and older than 70 years), before and during COVID-19, statistical significance was noted only in patients aged 11 to 20 (p=0.016). For clinical specimens (stool, blood, urine, pus, etc.), statistical significance was found only in blood specimens (p=0.036). The four most predominant Salmonella serogroups were B (31.1%), C (30.6%), E (15.7%), and D (11.4%). S. Typhi was present in 2.1% (4/193) of Salmonella isolates during COVID-19. The findings of a susceptibility test using the disk diffusion method for four commonly used drugs in treatment of severe salmonellosis as ampicillin, cefotaxime, ciprofloxacin, trimethoprim/sulfamethoxazole, before and during COVID-19 demonstrated statistical significance only in Salmonella serogroup D (p=0.028). Overall, drug susceptibility of Salmonella serogroup B, C, D, and E was ampicillin (range 15.1% to 55.9%), cefotaxime (range 66.7% to 100%), ciprofloxacin (range 18.8% to 59.1%), and trimethoprim/sulfamethoxazole (range 70.0% to 93.8%). Conclusion(s): The present study results suggested the importance of monitoring the prevalence of Salmonella at a hospital in Bangkok. The antibiogram of susceptibility helps provide guidelines for clinician to consider empirical treatment.Copyright © 2023 JOURNAL OF THE MEDICAL ASSOCIATION OF THAILAND.
ABSTRACT
Objective The havoc caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic could not have been predicted, with children being affected worldwide. Testing for SARS-CoV-2 infection helped to define the interventions against the spread of the disease. A polymerase chain reaction (PCR) test has been the mainstay of diagnostic testing. Cycle threshold (Ct) is a semiquantitative value that indicates approximately how much viral genetic material was in the sample. The aim of this study was to evaluate the impact of Ct values among children with SARS-CoV-2 infection. Methods Between May 3, 2020 and August 3, 2020, clinical laboratory input and the data of patients with positive SARS-CoV-2 PCR tests were retrospectively studied. Results There was no statistical significance between Ct values and the patient's status, symptoms other than fever, or other laboratory findings. However, the Ct value of patients who had symptoms at the time of admission to the hospital was significantly lower. Conclusion In this study, symptomatic patients had lower Ct than asymptomatic patients that reflected higher viral loads. In evidence-based medicine applications, it might be useful to correlate the clinical history with laboratory test results. Even symptomatic patients with high Ct value coinfections, or an alternative acute infection, should be considered. © 2022. Thieme. All rights reserved.
ABSTRACT
(1) Background: During the COVID-19 outbreak, several studies showed an increased prevalence of extended-spectrum ß-lactamase producing Enterobacterales (ESBL-PE) carriage in intensive care units (ICUs). Our objective was to assess the impact of antibiotic prescriptions on the acquisition of ESBL-PE in ICUs during the COVID-19 crisis. (2) Methods: We conducted an observational study between 1 April 2020, and 31 December 2021, in the medical-surgical ICU of the Cayenne General Hospital. We defined two periods: Period 1 with routine, empirical antibiotic use, and Period 2 with no systematic empiric antibiotic prescription. (3) Results: ICU-acquired ESBL-PE carriage was 22.8% during Period 1 and 9.4% during Period 2 (p = 0.005). The main isolated ESBL-PE was Klebsiella pneumoniae (84.6% in Period 1 and 58.3% in Period 2). When using a generalized linear model with a Poisson family, exposure to cefotaxime was the only factor independently associated with ESBL-PE acquisition in ICU (p = 0.002, IRR 2.59 (95% IC 1.42-4.75)). The propensity scores matching estimated the increased risk for cefotaxime use to acquire ESBL-PE carriage at 0.096 (95% CI = 0.02-0.17), p = 0.01. (4) Conclusions: Exposure to cefotaxime in patients with severe COVID-19 is strongly associated with the emergence of ESBL-PE in the context of maximal infection control measures.
ABSTRACT
Aims Introduction WHO designated the variant B.1.1.529, also known as Omicron, as a variant of concern in November 2021. Preliminary evidence suggests this particular variant to be highly infectious although the disease severity is relatively less as compared to Delta variant. We collated data for infants under 3 months of age who were admitted in Paediatric Assessment Unit (PAU) and tested positive for Omicron. We debate if there is a rationale of carrying out lumber puncture in such neonates especially considering this variant has been observed to be associated with milder disease. Aim The primary aim of our study was to study the clinical characteristics of < 3-month old babies admitted in PAU. The secondary aim of our retrospective review was to assess the need (and timing) of lumber puncture in this cohort. Methods We retrospectively collected data on infants under 3- months of age who were admitted in PAU from November 2021 to January 2022 and had confirmed RT-PCR test for Omicron variant of SARS CoV2. Two independent observers went through the discharge summaries to note down clinical characteristics (signs and symptoms of presentation, investigations carried out, management plan and final outcome) of these infants. We used our hospital test reporting system to confirm biochemical investigation results. Results Table 1 sums up the clinical characteristics of the 7 infants (up to 3-month of age) who were admitted to PAU (November 2021 to January 2022) and tested positive for Omicron variant: 1308 Table 1 Clinical characteristics of Omicron positive neonates Abbreviation: cef- Cefotaxime, Amx: Amoxicillin, Neg, Negative Conclusion Summary Clinical characteristics of neonates admitted to PAU who tested positive for Omicron variant were variable and included high temperature (4 out of 7), reduced feeds (3 out of 7), mottled appearance (2 out of 7) and jaundice. Majority of these neonates received broad spectrum antibiotics for first 48-hours and they remained well since admission. The CRP in majority (5 out of 7) of these neonates was within normal range. All 7 neonates were discharged home with none requiring escalation of care. Conclusion Our retrospective observational study data suggests Omicron variant being associated with milder disease severity although it is a small single centre study with limited sample size.

ABSTRACT
[Background] The epidemic of novel coronavirus disease 2019 (COVID-19) at the end of 2019 brought challenges to food safety. 【Objective】To evaluate the contamination of Listeria monocytogenes in fresh pork sold in the post-epidemic era. [Methods] During the epidemic period from 2020 to 2021, fresh pork from different locations, different packaging methods and different seasons were selected to analyze the contamination rate and contamination level of Listeria monocytogenes, and the epidemiological characteristics of the isolated strains were analyzed. [Results] The contamination rate of Listeria monocytogenes in fresh pork was 15.28% (77/504), and the contamination rate in pork direct-sale stores and farmers' markets was higher than that in supermarkets. Among different packaging methods, the contamination rates of pre-packaging and simple packaging were higher than those of bulk samples, and there were significant differences in the contamination rates in different quarters, with the highest contamination rate in the third quarter, which was 27.78%. Quantitative results found that 40.26% exceeded 10 MPN/g (MPN: most probable number), and 3 samples had contamination levels over 100 MPN/g. The results of serotype analysis showed that 1/2a-3a (48.05%) and 1/2c-3c (44.16%) were the main serotypes. The results of drug resistance test showed that 19.50% of the isolates were multi-drug resistant, 2 (2.60%) were sensitive to all antibiotics, 68 (88.30%) were resistant to oxacillin, and 46 (59.70%) were resistant to oxacillin. Ampicillin-resistant, 45 strains (58.40%) were resistant to cefotaxime. 【Conclusion】In the post-epidemic era, there are different degrees of Listeria monocytogenes contamination in the marketed fresh pork in different locations, different packaging methods and different seasons. The contamination level of individual products is high, and the serum distribution and drug resistance characteristics are diverse. It is necessary to strengthen food safety supervision to reduce the occurrence of foodborne diseases.
ABSTRACT
Minmin, a 1-year-old male local cat weighing 4.3 kg has decreased appetite and an enlarged abdominal cavity. Based on physical examination, there was abdominal distension. Routine hematology and blood biochemical examinations were performed which showed chronic inflammation and abnormal liver and kidney function. Radiographic examination and abdominocentesis showed fluid accumulation in the abdominal cavity (ascites) with pale yellow fluid and thickened liquid consistency. The results of the rivalta test showed a positive accumulation of exudate which was characterized by a jellyfish-like formation. The cat was diagnosed with effusive feline infectious peritonitis. The therapies given are diuretic furosemide 5 mg/kg BW (twice a day) intravenously, antibiotic cefotaxime sodium 30 mg/kg BW (twice a day) intravenously, anti-inflammatory dexamethasone 0,5 mg/kg BW (twice a day) subcutaneously, hepato-protector betaine 2.5 mg/kg BW (every two days) subcutaneously, and keto acid 11 mg/kg BW orally (every two days). The results of treatment for one week only provide temporary results in reducing the degree of abdominal distension. The cat died in the sixth month after therapy.
ABSTRACT
Klebsiella pneumoniae is a common bacterial pathogen causes wide range of infections all over the world. The antimicrobial resistance of K. pneumoniae is a global concern and expresses several virulence factors contributing to the pathogenesis. The incidences of bacterial co-infection in viral pneumonia are common. Increased risk of K. pneumoniae co-infection in viral respiratory tract infection should be alerted in COVID-19 pandemic period. The study aims to detect the association between antimicrobial resistance and factors causing pathogenicity of K. pneumoniae. For the current study, 108 K. pneumoniae clinical isolates were included. Antimicrobial susceptibility test was done by Kirby-Bauer disc diffusion method according to CLSI guidelines. Virulence factors such as biofilm formation, haemagglutination, haemolysins, hypermucoviscocity, siderophore, amylase, and gelatinase production were determined by phenotypic method. In this study K. pneumoniae showed high level of antimicrobial resistance towards ampicillin (92.59%) followed by amoxicillin-clavulanic acid (67.59%) and cotrimoxazole (47,22%). An important association between biofilm formation and antimicrobial resistance was found to be statistically significant for cotrimoxazole (P-value 0.036) and amoxicillin-clavulanic acid (P-value 0.037). Other virulence factors like hypermucoviscocity, haemagglutination, amylase, and siderophore production were also showed a statistically significant relation (P-value <0.05) with antimicrobial resistance. Further molecular studies are necessary for the identification of virulence and antimicrobial resistance genes, for the effective control of drug-resistant bacteria.
ABSTRACT
Background. Listeria monocytogenes is a gram-positive, facultative anaerobic bacillus common in the intestinal flora of many animals and humans. We describe an unusual case of meningitis by Listeria monocytogenes (LM) complicated by hydrocephalus in a child with dermatomyositis. Methods. A 15-year-old girl presented to an outside hospital (OH) after a threeday history of headache, fever and was hospitalized with a diagnosis of meningitis and lumbar puncture performed. CSF sample could not be evaluated clearly due to its hemorrhagic nature. Her past medical history was significant for dermatomyositis for five years. She had received induction of IVIG five days prior. She was also taking cyclosporin A and hydroxychloroquine. She was empirically treated with intravenous cefotaxime, vancomycin, and acyclovir. She was urgently transferred to the theatre for an external shunt placement in the right lateral ventricle. The interval between the first symptoms and the diagnosis of hydrocephalus was around 4 days. CSF from this catheter showed growth of LM with sensitivity to meropenem and resistance to erythromycin, ampicillin, and sulfamethoxazole-trimethoprim. Gram staining of CSF resulted negative for bacteria. Cefotaxime was switched to intravenous meropenem. Immunological screening of cellular and humoral immunity, complement, and blood iron levels were normal. SARS-Cov2 PCR and HIV tests were negative. Herpes virus, mycobacterium tuberculosis real-time PCR, respiratory viral panel studied in the CSF sample were negative. MRI and Angio of the brain showed no abnormality. She is being followed in the pediatric intensive care unit as intubated. Results. In patients who received immunosuppressive medication, L. monocytogenes should be evaluated in the differential diagnosis of central nervous system infections. Even if effective antibiotic therapy has been initiated, this case highlights the need of recognizing early hydrocephalus as a consequence of Listeria meningitis in children with neurological deterioration a few days after initial presentation. Conclusion. The literature on the management and outcome of Listeria meningitis-related hydrocephalus in children is limited.
ABSTRACT
The WHO has set Defined Daily Dose which represent the average daily dose of an antibiotic in a standard patient. The DDD mai nly focuses on population-based parameters & assumes that patients as well as hospitals are homogenous entities. DOTs are very useful in order to classify antibiotic days based on patient-level exposure. DOTs merely mean the number of days that a patient is on an antibiotic, irrespective of dose. DOTs signifies that the underlying assumptions about antibiotic dosing was appropriate. Additionally, when patients receive more than one antibiotic, supplementary DOT may be counted. The 300-bed tertiary care medical center serves adults and paediatrics. An all-time Microbiology Consultant and a Clinical Pharmacology trainee used to go for round daily and used to collect data for ASP for the period of 3 months that is April to June,2021. In this study we have compared DOT of some important antibiotics for a specific period of time for both COVID and NON COVID patient. ASP-focused antibiotics were antibiotics routinely evaluated by the ASP team for appropriateness during therapy and the potential to optimize their appropriate use through policies, protocols, formulary restrictions, or clinician education. ASP-focused antibiotics included meropenem, linezolid, pip-taz, poly b, colistin, teicoplanin. In this study we have compared the DDD for 2 specific period of time for better understanding the consumption of those antibiotics. In conclusion, following the initiation of an ASP, significant decreases in utilization, increases in cost savings occurred. In our study we have reduced the consumption and DDD of linezolid which is clinically significant. When it comes to DOTs;We have reduced the DOTs of piptaz and teicoplanin for covid patient And Reduced the DOTs of meropenem and teicoplanin for non-covid patient which is clinically and statistically significant.
ABSTRACT
Bacterial meningitis is a serious infection that requires immediate treatment. Recommended empiric antimicrobial therapy is based upon the most likely pathogen, according to a patient’s age and immune status. Antimicrobial therapy should be modified after identification of the causative microorganism and results of susceptibility tests. Preventive measures include the use of vaccines that target Neisseria meningitidis, Haemophilus influenzae, and Streptococcus pneumoniae, as well as the use of chemoprophylaxis in selected situations. Pharmacists are in a key position to recommend appropriate antimicrobial therapy for the treatment and prophylaxis of bacterial meningitis and to ensure that patients are receiving recommended vaccinations.
