ABSTRACT
Background Prior studies indicated increased antimicrobial resistance in Ethiopia, with related health, economic, and environmental costs. Knowing an institutions and population microbiologic profile allows for proper antibi-otic treatment, which substantially impact patients' outcomes such as healthcare related costs, morbidity, and mortality. The current study assessed the bacteriologic profile, resistance pattern, and treatment outcome in Lancet General Hospital. Method A retrospective cohort study on the bacteriologic profile, antibiotics resistance pattern, and outcome of patients was done on 128 eligible patients who were admitted to Lancet General Hospital from June 2022 to June 2023. Data from all hospitalized patients with culture-confirmed infection were analyzed. SPSS version 26.0 was used to analyze the data. Association between independent and dependent variables was analyzed using binary logistic regression model. Results Gram-negative bacteria were recovered in 77% of the cases. Extended-spectrum beta-lactamase producing Enterobacteriaceae was found in 37.5% (54) isolates and carbapenem resistant bacteria were identified in 27.8% of patients. In-hospital mortality from multidrug resistant bacterial infection was 14.8%. Age ≥ 65 years, presence of septic shock, and presence of carbapenem-resistant bacteria were independently associated with in-creased in-hospital mortality. Conclusion High number of resistant microorganisms was isolated, and increased mortality was documented from infections caused by carbapenem-resistant bacteria. Multi-center studies should be done to determine the extent of resistant organisms in health facilities throughout the country. epidemiology, and the findings should be factored into clinical decision making and program design for disease prevention, screening, and treatment. It also calls for further prospective research to learn more about the conditions in the context of additional relevant personal and clinical characteristics

Background: The inappropriate use of antibiotics results in the emergence of antimicrobial resistance and adverse clinical and economic outcomes in hospital in-patients. A lack of institutional and national antibiotic guidelines promotes inappropriate antibiotic use. The objectives of this study are to evaluate the appropriateness of antibiotic prescribing, and the quality of antibiotic use in medical wards of the Lagos University Teaching Hospital, Lagos, Nigeria. Methodology: This was a descriptive cross-sectional study of patients admitted and placed on antibiotics in the medical wards of Lagos University Teaching Hospital between July 2013 and August 2014. The appropriateness of antibiotic therapy was determined by compliance with the guidelines of the Infectious Diseases Society of America (IDSA). Results: A total of 350 hospitalized patients on antibiotic therapy during the period of the study were reviewed, including 197 (56.3%) males and 153 females (43.7%). The mean age of the patients was 48.7±17.6 years and a total of 539 initial antibiotics were empirically prescribed. Antibiotic therapy was considered inappropriate in 290 (82.9%) patients, of which 131 (37.4%) patients had no evidence of infection. Pneumonia (23.1%) was the most common indication for antibiotic use, out of which 59.3% had inappropriate antibiotic therapy. Overall, the most frequently prescribed initial empirical antibiotic classes were imidazole derivatives (32.4%) and cephalosporins (22.0%), while the most frequently prescribed inappropriate antibiotic classes were carbapenems (100.0%) and quinolones (89.3%). Conclusion: The study revealed a high rate of inappropriate antibiotic therapy. There is an imperative need to establish antimicrobial stewardship programmes to curb the inappropriate use of antibiotics in the hospital.

COVID-19 pandemic changed the face of global health and brought about new issues in global health security and economy. The World Health Organization published guidelines for clinical management of COVID-19 four months after declaration of COVID-19 as a pandemic. Scholarly reviews and studies from member states within WHO AFRO reveals significant deviation from the WHO published protocols on COVID-19. Assessment of national treatment protocols of 30 of 47 WHO AFRO member states showed widespread inappropriate use of antimicrobial agents for patients, which may worsen the global and concerning threat of antimicrobial resistance. There is need for adopting interventions that optimize antimicrobial use in the context of pre- and post-pandemic preparedness to ensure long-term effectiveness and sustainability for antimicrobials. Treatment guidelines are to be adopted or adapted depending on best clinical evidence available. Non-compliance with guidelines might lead to mismanagement of infectious diseases with attendant negative consequences including antimicrobial resistance and misdirection of critical resources and supplies amongst others.
La pandémie de COVID-19 a changé le visage de la santé mondiale et a soulevé de nouveaux problèmes en matière de sécurité sanitaire et d'économie mondiale. L'Organisation mondiale de la santé a publié des lignes directrices pour la gestion clinique du COVID-19 quatre mois après la déclaration du COVID-19 comme pandémie. Les revues scientifiques et les études des États membres de l'OMS AFRO révèlent un écart significatif par rapport aux protocoles publiés par l'OMS sur le COVID-19. L'évaluation des protocoles nationaux de traitement de 30 des 47 États membres de l'OMS AFRO a révélé une utilisation inappropriée et généralisée d'agents antimicrobiens chez les patients, ce qui pourrait aggraver la menace mondiale et préoccupante de résistance aux antimicrobiens. Il est nécessaire d'adopter des interventions qui optimisent l'utilisation des antimicrobiens dans le contexte de la préparation pré et post-pandémique afin de garantir l'efficacité et la durabilité à long terme des antimicrobiens. Les directives thérapeutiques doivent être adoptées ou adaptées en fonction des meilleures preuves cliniques disponibles. Le non-respect des directives pourrait conduire à une mauvaise gestion des maladies infectieuses avec des conséquences négatives qui en découlent, notamment la résistance aux antimicrobiens et une mauvaise orientation des ressources et fournitures essentielles, entre autres.

Background: Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus (DM) which is associated with high morbidity and mortality. There is high rate of bacteria colonization especially in those with tendencies for poor wound dressing. This is accompanied by high rate of inappropriate antibiotic usage. The aim of this study is to characterize microbial pathogens colonizing foot ulcers of diabetic patients in Enugu, Nigeria, and to determine the antibiotic susceptibility of these isolates. Methodology: This was a descriptive cross-sectional study of consecutively enrolled diabetic patients with foot ulcers in two tertiary healthcare facilities in Enugu, Nigeria, between May 2021 and February 2022. A structured questionnaire was used to obtain socio-demographic and clinical data of the patients. Pus samples and/or tissues were collected from the ulcer lesion of each patient for aerobic and anaerobic microbial cultures and biochemical identification using standard conventional techniques. Results: A total of 310 diabetic patients with foot ulcers were recruited into the study, with 62.3% (193/310) males and 37.7% (117/310) females, and mean age of 56.0±13.9 years. Bacteria and yeast were isolated from samples of 280 (90.3%) patients while samples of 30 (9.7%) patients had no microbial growth. Males had higher frequency of microbial isolates (90.7%, 175/193) than females (89.7%, 105/117), while the age group ≤ 40 years had higher frequency of microbial isolates (100%, 43/43) compared to other age groups, although the differences are not statistically significant (p>0.05). The distribution of the isolates showed that 15.7% (44/280) were monomicrobial while 84.3% (236/280) were polymicrobial. The highest single isolate was Bacteroides fragilis with 5.0% (14/280), followed by Staphylococcus aureus with 3.2% (9/280). Bacteroides fragilis and S. aureus occurred as the highest combined bacteria isolates with 5.7% (16/280). Most of the patients were colonized by combination of bacterial isolates. The susceptibility indicates that most of the anaerobic bacteria were sensitive to metronidazole while S. aureus isolates were resistant to ofloxacin at a rate of 65.0%. Conclusion: The findings in this study showed that there is high bacteria and fungi colonization of foot ulcers of diabetic patients in Enugu, Nigeria. Routine care of wounds especially frequent changes of dressing materials and the use of potent antiseptics, are recommended.

Background: Hepatitis C virus (HCV) infection is a global health problem and continues to be a major disease burden in the world, associated with serious health challenges including liver cirrhosis, cancer, lymphomas and death. This study was carried out to determine the prevalence of HCV infection among students of the University of Calabar. Methodology: In a cross-sectional study, 200 students were tested for the presence of anti-HCV antibodies using a rapid immunochromatographic (ICT) assay (CTK Biotech, Inc. USA). Seropositive samples were confirmed using reverse transcriptase-polymerase chain reaction (RT-PCR) assay for detection of HCV RNA. Structured questionnaires were used to collect subjects' socio-demographic data and risk factors of infection. Data were analyzed using SPSS version 16.0, with the level of significance set at p<0.05. Results: Of the 200 students screened, the seroprevalence of HCV was 15.0% (n=30) and 9.5% (n=19) was positive for HCV RNA by RT-PCR assay. The prevalence of anti-HCV antibody was significantly higher in females (18.8%, 12/64) than males (13.2%, 18/136) (x2=3.84, p=0.036). Alcohol consumption (OR=4.67, 95% CI=2.04-10.67, p=0.002), skin piercing (OR=32.99, 95% CI=5.95-72.37, p<0.0001), multiple sexual partners (OR=4.03, 95% CI=1.7-9.6, p=0.0018), and history of blood transfusion (OR=8.00, 95% CI=2.97-21.58, p<0.001) were risk factors significantly associated with HCV infection in the study participants. Conclusion: The findings of 15.0% and 9.5% prevalence of HCV infection by anti-HCV antibody and HCV RNA, respectively in this study, showed that there is relatively high prevalence of HCV infection among the students' population in University of Calabar, Nigeria. Hence, routine medical screening of students for HCV infection using rapid ICT and RT-PCR techniques is hereby recommended.
Contexte: L'infection par le virus de l'hépatite C (VHC) est un problème de santé mondial et continue de représenter un fardeau de morbidité majeur dans le monde, associé à de graves problèmes de santé, notamment la cirrhose du foie, le cancer, les lymphomes et la mort. Cette étude a été réalisée pour déterminer la prévalence de l'infection par le VHC parmi les étudiants de l'Université de Calabar. Méthodologie: Dans une étude transversale, 200 étudiants ont été testés pour la présence d'anticorps anti-VHC à l'aide d'un test immunochromatographique rapide (ICT) (CTK Biotech, Inc., USA). Les échantillons séropositifs ont été confirmés à l'aide d'un test de réaction en chaîne par transcriptase inverse-polymérase (RT-PCR) pour la détection de l'ARN du VHC. Des questionnaires structurés ont été utilisés pour collecter les données sociodémographiques des sujets et les facteurs de risque d'infection. Les données ont été analysées à l'aide de SPSS version 16.0, avec le niveau de signification fixé à p <0,05 Résultats: Parmi les 200 étudiants dépistés, la séroprévalence du VHC était de 15,0% (n=30) et 9,5% (n=19) étaient positifs à l'ARN du VHC par test RT-PCR. La prévalence des anticorps anti-VHC était significativement plus élevée chez les femmes (18,8%, 12/64) que chez les hommes (13,2%, 18/136) (x 2=3,84, p=0,036). Consommation d'alcool (OR=4,67, IC 95%=2,04-10,67, p=0,002), perçage cutané (OR=32,99, IC 95%=5,95- 72,37, p <0,001) Conclusion: Les résultats de 15,0 % et 9,5 % de prévalence de l'infection par le VHC par les anticorps anti-VHC et l'ARN du VHC, respectivement dans cette étude, ont montré qu'il existe une prévalence relativement élevée de l'infection par le VHC parmi la population étudiante de l'Université de Calabar, au Nigéria. Par conséquent, un dépistage médical de routine des étudiants pour l'infection par le VHC à l'aide de techniques rapides de TIC et de RT-PCR est recommandé.

Background@#Based on the 2017-2020 annual report of the Department of Health-Antimicrobial Resistance Surveillance Program, significant resistance patterns have been observed for common disease-causing pathogens. In the hospital setting, antimicrobial stewardship programs have been implemented to optimize the use of antimicrobials. Drug utilization review studies provide essential feedback to improve prescribing and use of medications.@*Objectives@#This study aimed to review drug utilization of monitored parenteral antimicrobials among patients admitted from January to December 2019.@*Methods@#The study employed a retrospective, cross-sectional, descriptive research design. A retrospective chart review of drugs administered to patients was conducted.@*@#Results. A total of 821 patients charts met the inclusion criteria. The patients’ ages ranged from 18 to 98 years old and 52% were females. General Internal Medicine practitioners (28%) were the top prescribers of monitored parenteral antimicrobials primarily for the management of moderate-risk community-acquired pneumonia (39%). They were mostly indicated for empirical treatment of infections (94%) and were given for an average of 5.73 days. Only 58% of the total cases had orders for culture and sensitivity testing. Of which, principally 47% had colony cultures. Blood (29%) and sputum (27%) were the most common specimens taken for culture and sensitivity testing. The microorganisms often isolated were Escherichia coli (19%), Klebsiella pneumoniae (18%), and Staphylococcus aureus (9%). In addition, extended-spectrum beta lactamase-producing gram-negative pathogens (4%) and methicillin-resistant S. aureus (1%) were also isolated. All the microorganisms isolated showed most resistance to ampicillin (81%) and most susceptibility to colistin (100%). There were drug therapy-related problems encountered. There was one case of an adverse drug reaction (0.1%) and two cases of contraindications (0.2%). Therapeutic duplication was also observed in 5% of the cases. Moreover, 39% had instances of drug-drug interactions.Piperacillin-tazobactam had the highest consumption (79.50 defined daily doses/1,000-patient days) among the monitored parenteral antimicrobials. Some prescriptions were deemed inappropriate upon evaluation. 12% of cases were inappropriate based on the justification indicator. As for the critical indicators, duration of therapy (78%) was the main reason. Only four components of the DUE criteria indicators have met or exceeded the established threshold level.The cost analysis indicated that the total actual cost of therapy with the monitored parenteral antimicrobials amounted to ₱17,645,601.73. Considering Department of Health National Antibiotic Guidelines recommenda-tions, ideal total cost of treatment was ₱14,917,214.29. Potential cumulative cost savings of ₱2,728,387.44 could have been achieved for patients admitted last 2019.@*Conclusion@#Consumption of piperacillin-tazobactam was relatively high as compared to the other monitored parenteral antimicrobials covered in this study. Physicians at the study site seldom prescribe monitored parenteral antimicrobials as recommended by the National Antibiotic Guidelines. This is evidenced in the incidence of inappropriate therapy regimens, with inapt duration of therapy as the leading explanation.From the patient’s perspective, the main economic implication was on the direct medical costs, particularly the increased cost of the actual antimicrobial therapy prescribed to manage various infections. Adherence of physicians to the established guidelines and selection of the most cost-effective therapy could have resulted in considerable cost savings.

Abstract Background The COVID-19 pandemic has triggered crises in the public health sector that have complex and multifaceted interrelationships with antimicrobial resistance. It is important to evaluate the impact of COVID-19 on microbiological profile, antibiotic and alcohol gel consumption in Intensive Care Units (ICU). Methods This is a retrospective study undertaken in an infectious disease hospital located in Bahia/Brazil during three periods: from March 2019 to February 2020; from March 2020 to February 2021; and from March 2021 to February 2022. It was evaluated the incidence density of Candida spp and of multidrug-resistant Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE group) in blood, urine and tracheal secretion isolated 48 h after the patient's admission to the ICU, as well as the use of alcohol gel (in milliliters) and consumption of antibiotics in Defined Daily Dose (DDD) per 1,000 ICU patient-days in the previous year and in the first two years of COVID-19 pandemic. Results There was an increase in Candida spp. (5.81, p < 0.001, IRR = 10.47, 95 % CI 2.57‒42.62) and in carbapenem-resistant A. baumannii in clinical cultures (4.71, p < 0.001, IRR = 8.46, 95 % CI 2.07‒34.60), the latter mainly in tracheal secretions (3.18, p =0.02, IRR = 11.47, 95 % CI 1.58‒83.39). A rise in the consumption of ceftriaxone and piperacillin-tazobactam, along with an increase in the utilization of alcohol gel were observed. Conclusion The shifting microbiological profile can be attributed to both the unique characteristics of patients with COVID-19 and the adjustments made to healthcare facilities' structural and work routines. Understanding these changes is essential in addressing the accelerated impact of antimicrobial resistance during the pandemic. Therefore, conducting thorough reviews of institutional practices and routines becomes critical in mitigating the consequences of antimicrobial resistance and its implications for patient care.
ABSTRACT
Las resistencias bacterianas a antimicrobianos representan uno de los principales problemas en la actualidad, encontrándose dentro de las principales causas de muerte en todo el mundo. Latinoamérica y Argentina, lejos de ser una excepción,presentan incidencias crecientes de infecciones por gérmenes resistentes. Cada día, se conocen mejor los mecanismos de resistencia que presentan los bacilos gram negativos y algunos cocos positivos. El problema no surge sólo por el sobreuso de antimicrobianos en la medicina clínica. Su sobreutilización para maximizar los beneficios productivos en la pesca, la ganadería y la agricultura contribuyen a esta situación. Desde la perspectiva de la atención primaria de la salud,consideramos fundamental conocer todos los aspectos que forman parte de esta problemática para intentar mitigar el daño que las resistencias bacterianas generan a nivel global. Argentina se transformó en el primer país de la región y del continente en contar con una ley para prevenir y controlar la resistencia a los Antimicrobianos. Consideramos de vital importancia que se fomenten más y mejores políticas sanitarias de orden público para enfrentar este creciente desafío. (AU)
Nowadays, bacterial resistance to antimicrobials is one of the main problems, being one of the leading causes of death worldwide. Latin America and Argentina, far from being an exception, have an increasing incidence of infections by resistant germs. Every day, the resistance mechanisms of gram-negative bacilli and some positive cocci are better known. The problem does not arise only because of the overuse of antimicrobials in clinical medicine. Its overuse to maximize productive benefits in fishing, livestock, and agriculture also contributes to this issue. From the perspective of primary health care,it is essential to know all the aspects of this problem to mitigate the damage that bacterial resistance generates at a global level. Argentina became the first country in the region and the continent to have a law to prevent and control antimicrobial resistance. We consider it vitally important that more and better public health policies are promoted to face this growing challenge. (AU)

O Complexo K. pneumoniae (C-Kp) é o principal grupo de bacilos Gram-negativos responsáveis por infecções nosocomiais graves em todo o mundo e o tratamento empírico dessas infecções usualmente inclui os carbapenêmicos. O principal mecanismo de resistência a essa classe de antimicrobianos é a expressão de carbapenemases, e no Brasil, mais frequentemente as do tipo KPC. Em março de 2019 a ceftazidima-avibactam foi disponibilizada para uso clínico no Brasil, sendo amplamente utilizada no tratamento infecções causadas por bacilos gram-negativos produtores de KPC. Diversos países já relataram a presença de K. pneumoniae produtores de KPC resistentes à ceftazidima-avibactam. No entanto, há poucos relatos dessa ocorrência no Brasil. O objetivo deste trabalho foi caracterizar genotipicamente e fenotipicamente isolados do C-Kp produtores de KPC, resistentes à ceftazidima-avibactam. No período de julho/2019 a julho/2021, 46 isolados do C-Kp, um por paciente, foram detectados em diferentes sítios de infecção ou culturas de vigilância de pacientes internados em hospitais privados de seis estados brasileiros. Os isolados tiveram seu genoma completo sequenciado nas plataformas MiSeq e MinION para determinação da variante alélica de blaKPC e avaliação do seu contexto genético. As taxas de resistência ao ertapenem e à ceftazidima-avibactam foram calculadas a partir de banco de dados. A clonalidade dos isolados foi avaliada por PFGE e MLST. A localização plasmidial do gene blaKPC foi confirmada por conjugação e/ou transformação. A concentração inibitória mínima (CIM) para betalactâmicos foi determinada por microdiluição em caldo segundo o BrCAST. Ensaios imunocromatográficos, NG-Test CARBA-5 e O.K.N.V.I. RESIST-5, foram avaliados quanto à sua performance na detecção de variantes KPC. A taxa de resistência ao ertapenem entre isolados do C-Kp aumentou 15,6% em 2019 para 27,3% em 2021. A taxa de resistência à ceftazidima-avibactam entre isolados do C-Kp resistentes ao ertapenem aumentou de 4,2% em 2019 para 17,2% em 2021. Onze isolados apresentaram novas variantes de KPC designadas KPC-103 a KPC-108 e KPC-139 a KPC-143. Os demais isolados apresentavam variantes de KPC já descritas, sendo a KPC-33 a variante mais frequente (36%). Quinze grupos clonais foram identificados, sendo que a maioria dos isolados pertencia ao ST11. O grupo clonal A foi o mais numeroso e pertencia ao ST258. A principal variante detectada nesse grupo foi a KPC-33. Diferentes grupos de incompatibilidade foram identificados em plasmídeos alberguando blaKPC, sendo os grupos IncN (n=12) e IncF, com replicons FII(K)-FIB (n=11), os grupos mais frequentes, seguido de InX3-IncU (n=9) e IncQ1 (n=1). Dos 46 isolados resistentes à ceftazidima-avibactam, 36 foram capazes de transferir o gene blaKPC para cepas receptoras. A maioria dos isolados foi sensível dose padrão ou sensível aumentabdo exposição ao meropenem e apresentaram redução significativa da CIM quando o avibactam foi adicionado ao aztreonam. O NG-Test CARBA-5 detectou 12 das 24 variantes testadas enquanto que o O.K.N.V.I. RESIST-5 detectou apenas nove variantes. A grande diversidade de variantes KPC, e a predominância do grupo clonal ST11, e da KPC- 33 retratam um cenário preocupante no Brasil
The K. pneumoniae Complex (C-Kp) is the main group of gram-negative bacilli responsible for serious nosocomial infections worldwide and the empirical treatment of these infections usually includes carbapenems. The main mechanism of resistance to this class of antimicrobials is the expression of carbapenemases, and in Brazil, more frequently the KPC type. In March 2019, ceftazidime-avibactam was available for clinical use in Brazil, being widely used to treat infections caused by KPC-producing gram-negative bacilli. Several countries have already reported the presence of KPC-producing K. pneumoniae resistant to ceftazidime-avibactam; however, there are few reports of this occurrence in Brazil. This work aimed to genotypically and phenotypically characterize KPC-producing C-Kp isolates resistant to ceftazidimeavibactam. From July 2019 to July 2021, 46 C-Kp isolates, one per patient, were detected in different sites of infection or surveillance cultures from patients admitted to private hospitals in six Brazilian states. The isolates had their complete genome sequenced on the MiSeq and MinION platforms to determine the allelic variant of blaKPC and evaluate its genetic context. Resistance rates to ertapenem and ceftazidime-avibactam were calculated from a database. The clonality of the isolates was evaluated by PFGE and MLST. The plasmid location of the blaKPC gene was confirmed by conjugation and/or transformation. The minimal inhibitory concentrations for beta-lactams were determined by broth microdilution according to BrCAST. Immunochromatographic assays, NG-Test CARBA-5 and O.K.N.V.I. RESIST-5, were evaluated for its performance in detecting KPC variants. The resistance rate to ertapenem among C-Kp isolates increased from 15.6% in 2019 to 27.3% in 2021. The resistance rate to ceftazidime-avibactam among ertapenem-resistant C-Kp isolates increased from 4.2% in 2019 to 17.2% in 2021. Eleven isolates showed new KPC variants designated KPC-103 to KPC-108 and KPC-139 to KPC-143. The remaining isolates presented previously described KPC variants, with KPC-33 being the most common variant (36%). Fifteen clonal groups were identified, with most isolates belonging to ST11. Different incompatibility groups were identified in plasmids harboring blaKPC, with the IncN (n=12) and IncF groups, with FII(K)-FIB(n=11) replicons, being the most frequent groups, followed by InX3-IncU (n= 9) and IncQ1 (n=1). All IncX3-IncU plasmids were approximately 46 kb in size and were identified among isolates belonging to the largest identified clonal group (A) and ST258. The main variant detected in this group was KPC-33. Of the 46 ceftazidime-avibactam-resistant isolates, 36 were able to transfer the blaKPC gene to recipient strains. Most isolates were susceptible standard dose or susceptible increased exposure to meropenem and showed a significant decrease in MIC when avibactam was added to aztreonam. The NG-Test CARBA-5 was able to detect 12 of the 24 variants evaluated while the O.K.N.V.I. RESIST-5 detected only nine variants. The great diversity of KPC variants, the predominance of the ST11 clonal group, and KPC-33 portray a worrying scenario in Brazil

@#The increasing number of drug-resistant pathogens is a global issue and becoming worse because it has reduced the effectiveness of current antibiotics in the management of infectious diseases. Therefore, this situation highlights the urgency of an action plan to identify and develop novel and potent antimicrobials derived from natural resources. Therapeutic compounds from natural resources can offer novel, straightforward approaches against pathogenic bacteria with the least toxic manifestations and a low risk of acquiring resistance. Marine organisms and coastal plants receive much interest among researchers nowadays for developing new pharmaceuticals because they are rich in secondary metabolites that have various pharmacological effects, such as antibacterial, anti-cancer, antiviral, anti-inflammatory and others. This review's goal is to highlight the phytochemical components of marine organisms and coastal plants that might be accountable for their antibacterial properties that have been scientifically confirmed and can be potential aids in treating infectious diseases caused by multidrug resistant (MDR) bacteria in humans.
ABSTRACT
Objective To analyze the clinical characteristics and the antimicrobial resistance of respiratory tract infection in children in Baoshan City,guide clinicians to rationally apply antibiotics,and improve the success rate of treatment.Methods Retrospective analysis of the distribution characteristics and drug sensitivity results of 1039 strains of pathogens detected in pediatric inpatients of hospitals from 2019 to 2022 was conducted.Results The main pathogens causing the respiratory infections in children in Baoshan area were Streptococcus pneumoniae,Escherichia coli,Staphylococcus aureus,Haemophilus influenzae,Klebsiella pneumoniae and Pseudomonas aeruginosa.Analysis of the drug sensitivity results of pathogenic bacteria with a detected quantity greater than 80 revealed that Streptococcus pneumoniae had a high resistance rate to erythromycin,clindamycin,and compound sulfamethoxazole.The resistance rates of penicillin,ceftriaxone,cefotaxime,and meropenem were P<0.05,and the difference was statistically significan.Methicillin-resistant Staphylococcus aureus(MRSA)was11.1%;CTX/CRO-R-ECO,CTX/CRO-R-KPN,CR-ECO and CR-KPN were lower than the 2021 ISPED level;The P.aeruginosa drug resistance rate and H.influenzae's ampicillin and ampicillin/sulbactam were higher than the 2021 ISPED level.Conclusion The treatment of respiratory tract infections in pediatric patients faces great challenges.The non-standard use of empirical medication has led to the emergence of multidrug-resistant bacteria,and the selection of anti infection treatment drugs is limited.Therefore,it is imperative to grasp the epidemic characteristics and drug resistance of pathogenic bacteria in the local area.

OBJETIVO: Caracterizar y evaluar las prescripciones de tigeciclina en pacientes internados en un hospital universitario, durante los años 2017 y 2018. METODOLOGÍA: Estudio observacional retrospectivo, donde se caracterizaron los pacientes, las terapias, la microbiología asociada, los desenlaces clínicos y las reacciones adversas asociadas a los tratamientos con tigeciclina. Se determinó la proporción de prescripciones apropiadas por un comité de expertos y el consumo de tigeciclina medido en DDD/100 camas-día. RESULTADOS: Se caracterizaron 89 pacientes, de los cuales 67 (75,3%) cumplieron los criterios de selección. El 53,7% de los pacientes eran hombres, con una edad promedio de 60 ± 15 años. El principal motivo de hospitalización fue quirúrgico (65,7%). El 67,1% de los tratamientos con tigeciclina se inició en una Unidad de Paciente Critico y el foco de infección predominante fue abdominal (64,3%). El 50% de las terapias con tigeciclina fueron dirigidas según la microbiología identificada. En 65,7% de los casos se usó tigeciclina como monoterapia en la dosis habitual (62,9%). Náuseas (8,6%), diarrea (7,1%) y vómitos (4,3%) fueron los efectos adversos más reportados. El 84,3% de los tratamientos se consideraron apropiados. El año 2017 se consumió 0,4 DDD/100 camas-día y 0,6 DDD/100 camas/día el 2018, siendo la UCI el servicio que presentó el mayor uso en ambos años. DISCUSIÓN: Tigeciclina fue utilizada principalmente en monoterapia para el tratamiento de infecciones intraabdominales en pacientes hospitalizados, por motivos quirúrgicos, en una unidad de paciente crítico, en las dosis habituales recomendadas de 100 mg como dosis de carga seguida de 50 mg cada 12 hs IV. En 50% de los casos, la terapia fue dirigida según microbiología. Los eventos adversos más habituales fueron los gastrointestinales. CONCLUSIÓN: La mayoría de las terapias prescritas fueron consideradas apropiadas por el comité de expertos.
BACKGROUND: The use of tigecycline has been increasing in recent years, due to increase in bacterial resistance and the scarcity of therapeutics alternatives. AIM: To characterize and evaluate the tigecycline prescriptions of patients hospitalized in a university hospital, during the years 2017 and 2018. METHODS: A retrospective observational study was carried out, where the patients, the therapies, the associated microbiology, the clinical outcomes and the adverse reactions associated with tigecycline were characterized. The proportion of appropriate prescriptions was determined by committee of experts and the consumption of tigecycline measure in DDD/100 bed-days. RESULTS: 89 patients who used tigecycline were characterized, of which 67 (75.3%) met the selection criteria. 53.7% of the patients were male, with a mean age of 60 +/- 15 years The main reason for hospitalization was surgical (65.7%). 67.1% of the treatments with tigecycline were started in a critical patient unit and the predominant focus of the infection was the abdomen (64.3%). 50% of the therapies with tigecycline were ordered according to the identified microbiology. In 65.7% of the cases, tigecyclin was used as monotherapy at the usual dose (62.9%). Nausea (8.6%), diarrhea (7.1%) and vomiting (4.3%) were the most reported adverse events. 84.3% of the treatments were considered appropriate. In 2017, 0.4 DDD/100 bed/days were consumed and 0.6 DDD/100 bed/days in 2018, with de ICU being the service that presented the highest use in both years. DISCUSSION: Tigecycline was mainly used as monotherapy for the treatment of intra-abdominal infections in patients hospitalized for surgical reasons in a critical patient unit at the usual doses of 100 mg loading followed by 50 mg every 12 hours IV. In 50% of the case the therapy was directed according to microbiology. The most common adverse events were gastrointestinal. CONCLUSION: Most of the prescribed therapies were considered appropriate by the expert committee.

The alarming increase in bacterial resistance to antibiotics globally has diluted sources other than the hospital and community, where water has taken on great importance. The aquatic environment is the source and natural habitat of a large number of microorganisms, including antibiotic-resistant bacteria, as well as being considered one of the main receptors for antimicrobials, resistant bacteria and antibiotic resistance genes from human activities. Contamination of water with these emerging contaminants has serious implications for human health related to the spread of bacterial resistance and the emergence of new resistance mechanisms. This review provides a global description of the role of aquatic environments in the problem of bacterial resistance, the main sources of contamination, as well as the impact on Public Health. In this context, the need arises to address the problem of bacterial resistance from the perspective of "one health", where traditional surveillance, focused at the human and veterinary level, is articulated with environmental epidemiological surveillance, mainly in wastewater.

RESUMEN: El aumento de la resistencia y la escasez de nuevos antibacterianos ha requerido la reintroducción de antiguos antimicrobianos entre ellos colistín. OBJETIVO: Caracterizar la utilización de colistín durante el año 2017 en un hospital universitario, mediante la descripción de los pacientes, los tratamientos, la microbiología asociada y efectos adversos. PACIENTES Y MÉTODOS: Trabajo observacional retrospectivo. Se revisaron los datos de todos los pacientes que recibieron colistín intravenoso (IV) por al menos 48 horas, durante el año 2017. RESULTADOS: Se incluyeron 53 pacientes, equivalentes a 91 tratamientos. El foco respiratorio fue el principal (46,2%). El 68,1% de los tratamientos fue iniciado en la UCI. La mayoría de los pacientes tenía una hospitalización reciente (83,5%), y presentaban uso previo de antibacterianos (89%). Los dos patógenos mayoritariamente identificados fueron Pseudomonas aeruginosa y Klebsiella spp. El consumo promedio de colistín fue de 2,4 DDD/100 camas/día. El servicio que más consumió colistín fue la UCI, con 45,5 DDD/100 camas/día, usando generalmente la dosis de 3 MUI cada 8 horas IV y con una baja utilización de dosis de carga. CONCLUSIÓN: Colistín corresponde a un antimicrobiano de uso restringido a infecciones sospechadas o confirmadas por agentes bacterianos multi resistentes. En esta serie, su uso inicial fue principalmente empírico, en pacientes con factores de riesgo para resistencia antibacteriana; se usó en forma asociada a otros antimicrobianos, siendo el foco principal el respiratorio.
BACKGROUND: The increase in resistance and the shortage of new antibiotics has led to the reintroduction of old antimicrobials such as colistin. AIM: To evaluate the use of colistin during 2017 in a university hospital, through the characterization of patients and treatment, associated microbiology, response to treatment and adverse effects. METHODS: Retrospective observational design. The data of all patients who received colistin for at least 48 hours during the year 2017 were reviewed. RESULTS: 55 patients were included, equivalent to 144 treatments. The respiratory focus was the main one (57.9%). 64% of the treatments began in the ICU, while 7% in the ward. Most of the patients has a recent hospitalization (86.8%) and has previous use of antibiotics (90.4%). The two main pathogens identified were Pseudomonas aeruginosa and Klebsiella spp. In 87.1% of the cases with microbiological justifications for the use of colistin, a favorable response was obtained. The average consumption of colistin was 2.4 DDD/100 beds/day. The department that consumed the most colistin was the ICU, with 45,5 DDD/100 beds/day, generally using a dose of 3 MIU every 8 hours IV and with low use of loading doses. CONCLUSION: Colistin corresponds to an antibiotic whose use is restricted to infections suspected or confirmed by multi-resistant bacterial agents. Its initial use in this serie was mainly empirical, in patients with risk factors for antibiotics resistance, it was used in association with other antimicrobials, being the respiratory the main infectious focus.

Purpose: To report on the microbiological profile and antibiotic sensitivity patterns of infectious keratitis at a tertiary center in central India. Methods: The suspected case of severe keratitis underwent microbiological culture and identification using the VITEK 2 technique. Antibiotic susceptibility for different sensitivity and resistance patterns was analyzed. Demographics, clinical profile, and socioeconomic history was also documented. Results: Culture was positive in 233/455 (51.2%) patients. Pure bacterial growth was present in 83 (35.62%) patients and pure fungus was present in 146 (62.66%) patients. The most common bacterial cause of infectious keratitis was Pseudomonas followed by Staphylococcus and Bacillus. Pseudomonas showed 65%–75% resistance against levofloxacin, ceftazidime, imipenem, gentamycin, ciprofloxacin, and amikacin. Staphylococcus showed 65%–70% resistance against levofloxacin, erythromycin, and ciprofloxacin, with Streptococcus being 100% resistant to erythromycin. Conclusion: This study highlights the current trend of microbiological profiles of infectious keratitis and their antibiotic susceptibility at a rural setup in central India. Fungal predominance and increased resistance against the commonly used antibiotics were noted.
ABSTRACT
Aims: Our proposal aimed to evaluate Acyl Homoserine Lactones (AHL) as a functional marker for Multi drug resistant (MDR) potential in clinical isolates of Acinetobacter baumannii. We investigated the AHL production potential of clinical isolates using a biosensor assay directly on a commonly used agar media. Place and Duration of Study: Department of Molecular Diagnostics and Biomarkers, Gleneagles Global Hospitals, Lakdikapul, Hyderabad-500004. Methodology: Antimicrobial drug sensitivity testing (AST) was performed on 72 clinical isolates of A. baumannii against two front-line antibiotics, Imipenem (10µg) and Meropenem (10µg), by Kirby-Bauer disk diffusion method. Production of long chain Acyl Homoserine lactone (AHLs) in the clinical isolates of A. baumannii was tested by cross streaking with the biosensor Chromobacterium violaceum mutant strain CV026 and Agrobacterium tumefaciens (NTL4pZLR4) by agar plate diffusion assay. Screening and identification of the quorum sensing mediator gene abaI was done by PCR to confirm its presence in all the 72 clinical isolates. Results: Out of the 72 clinical isolates, 58 were Carbapenem resistant Acinetobacter baumannii (CRAB) and 14 were Carbapenem sensitive Acinetobacter baumannii (CSAB) for AST by agar disc diffusion method. None of our isolates produced short chain AHLs whereas all the isolates could produce varying amounts of long chain AHLs. Genotypic confirmation of AHL gene was obtained by abaI gene PCR. Conclusion: Carbapenems are the front-line antibiotics used to treat gram negative bacterial infections in emergencies and in the critical care units of hospitals. Clinical isolates A. baumannii has innate resistance to several antibiotics due to various mechanisms, biofilms forming the first line of defense against antibiotics for the bacterium. Our study used AST to carbapenem as the leading marker for MDR, assuming the innate resistance of A. baumannii to other beta lactam antibiotics. Our study brought out certain important observations namely: a) All clinical isolates of A. baumannii produced Quorum Sensing signal molecules, the AHLs b) the clinical isolates of A. baumannii did not produce any short chain AHLs b) All the clinical isolates of A. baumannii produced long chain AHLs c) AHL production is not specific to carbapenem drug resistance because even CSAB isolates produced AHL d) AHL production is inherent to all clinical isolates of A. baumannii and it apparently indicates an underlying biofilm potential and MDR trait in these A. baumannii isolates. e) AHLs could be a universal marker for revealing MDR trait and biofilm potential in clinical microbiology AST profiling protocols.
ABSTRACT
Background & objectives: Sepsis, including neonatal sepsis, remains a prevalent cause of morbidity and mortality in low- and middle-income countries such as India, representing 85 per cent of all sepsis-related deaths globally. Early diagnosis and timely initiation of treatment is challenging due to non-specific clinical manifestations and non-availability of rapid diagnostic tests. There is an urgent need for affordable diagnostics with fast turnaround time catering to the needs of end-users. Target product profiles (TPPs) have been found instrumental in developing ‘fit-for-use’ diagnostics, thus reducing the time taken to facilitate development and improving diagnosis. Hitherto, no such guidance or criteria has been defined for rapid diagnostics for sepsis/neonatal sepsis. We propose an innovative approach for developing the diagnostics for sepsis screening and diagnosis which can be utilized by diagnostic developers in the country. Methods: Three-round Delphi method, including two online surveys and one virtual consultation, was adopted to define criteria for minimum and optimum attributes of TPPs and build consensus on characteristics. Expert panel (n=23) included infectious disease physicians, public health specialists, clinical microbiologists, virologists, researchers/scientists and technology experts/innovators. Results: We present a three-component product profile for sepsis diagnosis, (i) screening with high sensitivity, (ii) detection of aetiological agent, and (iii) profiling of antimicrobial susceptibility/resistance, in adults and neonates with an option of testing different considerations. An agreement of >75 per cent was achieved for all TPP characteristics by Delphi. These TPPs are tailored to the Indian healthcare settings and can also be extrapolated to other resource-constraint and high-disease burden settings.
ABSTRACT
La cirugía de terceros molares es uno de los procedimientos más realizados dentro de la práctica odontológica, generalmente conlleva la prescripción de fármacos, incluidos antibióticos indicados para prevenir la aparición de procesos infecciosos. La resistencia antimicrobiana es considerada como un problema de salud pública a nivel mundial, por lo que el uso de antibióticos debe ser cauteloso. La solución electrolizada de súperoxidación ha demostrado tener efectos bactericidas, virucidas y ha sido utilizada para la prevención y el tratamiento de procesos infecciosos. El objetivo del presente estudio fue demostrar la efectividad de dicha solución en la prevención de infecciones posteriores a la cirugía de terceros molares. Se realizó un estudio aleatorizado, ciego, prospectivo en 20 pacientes utilizando un diseño split mouth, en donde cada paciente fue sujeto control y experimental, en el grupo control se irrigó durante el procedimiento con solución de súperoxidación y no se prescribió antibiótico posterior, mientras que en el grupo control se irrigó con solución fisiológica y se prescribió antibiótico posterior. Se realizaron 40 cirugías en 20 pacientes utilizando en cada paciente ambas terapéuticas. Se analizó el dolor postoperatorio, inflamación y presencia de infección. El dolor y la inflamación fueron ligeramente superiores en el grupo experimental al tercer día; sin embargo, al séptimo día los resultados fueron similares. No se presentó ningún caso de infección postoperatoria. El uso de solución de súperoxidación transoperatoria puede ser una herramienta muy útil en la prevención de infecciones postoperatorias posterior a cirugía de terceros molares en pacientes sanos en cirugías con dificultad leve a moderada (AU)
Third molar surgery is one of the most performed procedures in dental practice, generally involving the prescription of drugs including antibiotics indicated to prevent the onset of infectious processes. Antimicrobial resistance is considered a public health problem worldwide, so the use of antibiotics should be cautious. The electrolyzed super oxidation solution has been shown to have bactericidal and virucidal effects and has been used for the prevention and treatment of infectious processes. The objective of the present study was to demonstrate the effectiveness of said solution in the prevention of infections after third molar surgery. A randomized, blind, prospective study was conducted in 20 patients using a split mouth design where each patient was a control and experimental subject, in the control group they were irrigated during the procedure with super oxidation solution and no subsequent antibiotic was prescribed. while the control group was irrigated with physiological solution and a subsequent antibiotic was prescribed. Forty surgeries were performed on 20 patients using both therapies in each patient. Postoperative pain, inflammation and presence of infection were analyzed. Pain and inflammation were slightly higher in the experimental group on third day, however on seventh day the results were similar. There were no cases of postoperative infection. The use of trans operative super oxidation solution can be a very useful tool in the prevention of postoperative infections after third molar surgery in healthy patients undergoing surgeries with mild to moderate difficulty.(AU)

Background : Measuring antimicrobial consumption is necessary to understand the volume and patterns of use, to design appropriate interventions to reduce and rationalize its use. Materials and Methods : The antimicrobial consumption in Neurology ICU and IPD were measured over a 5-year period using WHO Defined Daily Dose (DDD) methodology. Results : There was an increasing trend in Antimicrobial Consumption (AMC) from 125.7 to 155.5 DDDs/100 days over 5 years with highest consumption in 2017-2018 (190.7 DDDs). The consumption of Watch group of antibiotics was higher than access group antibiotics both in ICU and IPD and constituted more than 75% of total antibiotic consumption. Conclusions : The initiation of empiric therapy though may be necessary depending on the patients condition, however, duration of antibiotic therapy and reducing usage of prophylactic antibiotics for aspiration pneumonia and reducing consumption of Watch group of antibiotics were identified as stewardship opportunities. Feedback on AMC data and persuasive educational interventions to rationalize and reduce antimicrobial use are required.
