Assessment of bacterial profile, antimicrobial susceptibility status, and associated factors of isolates among hospitalized patients at Dessie Comprehensive Specialized Hospital, Northeast Ethiopia.

BACKGROUND: Antimicrobial resistant bacteria among hospitalized patients are becoming a major public health threat worldwide, mainly in developing countries. Infections by these multidrug resistant pathogens cause high rate of mortality, prolong hospital stays, and affect individual and country economies in greater amounts. Thus, this study aimed to assess the bacterial profile, antimicrobial susceptibility status, and associated factors of isolates from hospitalized patients at the Dessie Comprehensive Specialized Hospital. METHODOLOGY: This hospital-based cross-sectional study was conducted between February and April 2021. Consecutive sampling was used to select the study participants. All bacterial isolates were identified using standard bacteriological techniques. Antibiotic susceptibility testing was performed using disk diffusion technique. The data was analyzed using SPSS version 25. Descriptive statistics and logistic regression were used. A P-value of less than 0.05 was considered statistically significant. RESULTS: Of 384 clinical samples (blood, urine, stool, wound, vaginal discharge, and ear discharge) processed 180 (46.9%) were culture positive. Overall, Escherichia coli was the predominant isolate (41; 22.8%), followed by Staphylococcus aureus (36; 20%). Most of the isolates were from blood (70; 38.9%). The level of overall drug resistance of the gram-negative bacteria isolates for ampicillin, tetracycline, and cotrimoxazole was (104; 88.1%), (79; 75.9%), and (78; 75.0%), respectively. The overall multidrug rate of isolates was 143 (79.4%). Variables such as history of invasive procedures, chronic underlying diseases, history of hospitalization, and habit of eating raw animal products were statistically significant for the acquisition of bacterial infection. CONCLUSIONS AND RECOMMENDATION: E. Coli and S. aureus were the most common isolates. Most of the isolates were resistant to commonly prescribed antibiotics. And also, consumption of raw animal products, chronic underlying disease, previous hospitalization, history of invasive procedures, and educational status were associated with the acquisition of bacterial infections. Therefore, routine antimicrobial susceptibility testing, proper patient management, wise use of antibiotics in clinical settings and health education are recommended.

Therapeutic efficacy and safety of artemether-lumefantrine combination therapy for the treatment of uncomplicated Plasmodium falciparum malaria at Teda Health Centre, Northwest Ethiopia, 2022/23.

BACKGROUND: The emergence of Plasmodium falciparum drug resistance against artemisinin-based combination therapy has threatened malaria control efforts. Since malaria control and elimination plans are dependent on these drugs, they must remain efficacious. However, resistance to these drugs was detected in low-transmission settings and is predicted to emerge in high-transmission settings, including in unspecified areas of Ethiopia. Therefore, this study aimed to assess the therapeutic efficacy and safety of artemether-lumefantrine for the treatment of uncomplicated P. falciparum malaria. METHODS: A single-arm prospective observational study was conducted at Teda Health Centre, Northwest Ethiopia, by following the 2009 World Health Organization efficacy study guidelines from September 2022 to February 2023. Patients with uncomplicated falciparum malaria were conveniently selected and treated with a standard dose of artemether-lumefantrine, along with a single low dose of primaquine. Then clinical and parasitological responses and haemoglobin levels were assessed during the 28-day scheduled follow-up. Blood films were examined and asexual parasites were quantified; axillary temperature was measured; and drug adverse events were assessed throughout the follow-up. Finally, the drug efficacy (adequate clinical and parasitological response) was determined by Kaplan-Meier and per-protocol analyses. The data were analysed using the WHO Excel spreadsheet and SPSS version 25 software. RESULTS: The success rates of PCR uncorrected and corrected Kaplan-Meier analysis on day 28 were 95.8% (95% CI 87.5-98.6) and 97.3% (95% CI 89.4-99.3), respectively. The per-protocol PCR uncorrected and corrected adequate clinical and parasitological responses were 95.5% (95% CI 87.5-99.1) and 97% (95% CI 89.5-99.6), respectively. On day-3, 97% of study participants were free of asexual parasitaemia, and all of them were fever-free on day-2. All of the gametocyte-positive patients at baseline were found to be negative for gametocytes on day-2. Moreover, the baseline mean hemoglobin of 13.10 g/dl increased slightly on day-14 to 13.27 g/dl but significantly on day-28 to 13.69 g/dl in a paired sample t test. All adverse events reported were mild. CONCLUSION: Artemether-lumefantrine continued to be an efficacious and safe drug for the treatment of uncomplicated Plasmodium falciparum malaria at the Teda Health Centre.

Prevalence of carbapenem-resistant gram-negative bacteria among neonates suspected for sepsis in Africa: a systematic review and meta-analysis.

BACKGROUND: The emergence and rapid spread of gram-negative bacteria resistant to carbapenems among newborns is concerning on a global scale. Nonetheless, the pooled estimate of gram-negative bacteria resistant to carbapenem that cause neonatal sepsis in developing nations remains unknown. Thus, this study aimed to determine the combined prevalence of gram-negative bacteria resistant to carbapenem in African newborns who were suspected of having sepsis. METHODS: All studies published from January 1, 2010, up to December 30, 2023, from PubMed, Science Direct, Scopus electronic databases, and the Google Scholar search engine were researched. Isolates tested for carbapenem from neonates with sepsis, English language papers conducted in Africa, and cross-sectional and cohort studies papers were included. Using PRISMA guidelines, we systematically reviewed and meta-analyzed studies that assessed the prevalence of carbapenem-resistant gram-negative bacteria. The "Joanna Briggs Institute" was used critically to evaluate the quality of the included studies. The data analysis was carried out using STATA™ version 17. Heterogeneity across the studies was evaluated using Q and I 2 tests. The subgroup analysis was done and, funnel plot and Egger's regression test were used to detect publication bias. A sensitivity analysis was conducted. RESULTS: All 36 studies were included in the meta-analysis and systematic review. The pooled prevalence of carbapenem resistance in Africa was 30.34% (95% CI 22.03-38.64%). The pooled estimate of gram-negative bacteria resistant to imipenem, and meropenem was 35.57% (95% CI 0.67-70.54%) and 34.35% (95% CI 20.04% - 48.67%), respectively. A. baumannii and Pseudomonas spp. had pooled prevalence of 45.9% (95% CI 33.1-58.7%) and 43.0% (95% CI 23.0-62.4%), respectively. Similarly, Pseudomonas spp. and A. baumannii also exhibited strong meropenem resistance, with a pooled prevalence of 29.2% (95% CI 4.8-53.5%) and 36.7% (95% CI 20.1-53.3%), respectively. E. coli and K. pneumoniae were the two most common isolates. CONCLUSION: There should be urgent antimicrobial stewardship practices, strengthened surveillance systems and effective treatment for neonates with sepsis. There was remarkable variation in resistance across the continent.

Antimicrobial resistance and ESBL production in uropathogenic Escherichia coli: a systematic review and meta-analysis in Ethiopia.

Background: Antimicrobial resistance (AMR) is a serious threat to global health systems. Escherichia coli is a major cause of urinary tract infections (UTIs). Understanding the AMR patterns of uropathogenic E. coli (UPEC) is crucial for effective public health interventions worldwide. Objectives: This systematic review and meta-analysis aimed to consolidate existing research and provide a comprehensive information on AMR UPEC in Ethiopia. Methods: We systematically searched databases such as PubMed, Web of Science, and Science Direct, along with including articles from Google Scholar. Data were extracted into Microsoft Excel and analysed using STATA 17.0. Cohen's kappa was computed to assess reviewer agreement, while the I2 statistic evaluated heterogeneity. Egger's tests were conducted to detect publication bias, and random-effects models were utilized to estimate the pooled resistance, with AMR rates for each antibiotic pooled separately. Results: UPEC showed resistance rates, ranging from 3.64% (95% CI: -4.38% to 11.67%) for amikacin to 85.32% (95% CI: 78.6%-92.04%) for ampicillin. Highest resistance was to ampicillin (85.32%), followed by amoxicillin at 82.52% (95% CI: 74.3%-90.74%), tetracycline at 60.67% (95% CI: 51.53%-69.81%) and trimethoprim/sulfamethoxazole at 57.17% (95% CI: 49.93%-64.42%). Conversely, resistance rates were lower for amikacin at 3.64% and meropenem at 5.26% (95% CI: 2.64%-7.88%). UPEC demonstrated a pooled MDR rate of 79.17% (95% CI: 70.32%-88.01%) and a pooled ESBL production rate of 29.16% (95% CI: 22.36%-38.55%). Conclusions: High levels of AMR were observed in UPEC strains, highlighting a critical public health issue requiring urgent action through robust antimicrobial stewardship and surveillance to preserve effective UTI treatment options.

Effect of Malaria and Schistosoma mansoni Coinfection on Selected Biochemical Profiles among Patients Attending Selected Health Institutions at Dembiya, Northwest Ethiopia.

Background: Malaria and schistosomiasis are infectious diseases that cause biochemical abnormalities. Malaria and Schistosoma mansoni coinfection causes exacerbations of health consequences and comorbidities. The study area is found in Ethiopia, where coinfection of malaria and S. mansoni is common. However, there is limited data on the biochemical profiles of patients coinfected with malaria and S. mansoni schistosomiasis in the study area. Hence, this study aimed to assess the effect of malaria and S. mansoni schistosomiasis coinfection on selected biochemical profiles. Methods: An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. Using a convenient sampling technique, 70 participants (35 cases and 35 controls) were enrolled in the study. Schistosoma mansoni was detected in stool samples using the wet mount and the Kato Katz method. To detect Plasmodium, both thick and thin blood films were prepared and stained with Giemsa. The blood sample was processed for the analysis of biochemical profiles. All data were analyzed using SPSS version 25. A p value of less than 0.05 was considered statistically significant. Results: The mean values of alanine aminotransferase and aspartate aminotransferase (37.1 U/L and 41.9 U/L, respectively) in coinfected participants were significantly higher than in the healthy control participants (17.4 U/L and 22.0 U/L, respectively) (p < 0.05). Also, the median values of creatinine, total bilirubin, and direct bilirubin (1.51 mg/dL, 2.35 mg/dL, and 0.91 mg/dL, respectively) in coinfected participants were significantly higher than in the healthy control participants (0.85 mg/dL, 0.42 mg/dL, and 0.12 mg/dL, respectively) (p < 0.05). However, median values of total protein (4.82 g/dL) and mean values of glucose (66.6 mg/dL) in coinfected participants were significantly lower than in the healthy control participants (total protein (7.64 g/dL) and glucose (91.9 mg/dL)) (p < 0.05). The results of biochemical profiles in healthy participants were significantly different from those with light, moderate, and heavy S. mansoni infection intensity in malaria and S. mansoni coinfection (p < 0.05). Schistosoma mansoni infection intensity had a positive correlation with biochemical profiles except for total protein and glucose, which correlated negatively in coinfected participants (p > 0.05). Conclusion: Biochemical profiles in coinfection were significantly changed as compared to healthy individuals. As a result, biochemical profile tests should be utilized to monitor and manage coinfection-related problems, as well as to reduce coinfection-related morbidity and death.

Assessment of the selected hematological profiles among malaria and Schistosoma mansoni co-infected patients, Northwest Ethiopia.

Malaria and schistosomiasis are infectious diseases that cause hematological profiles abnormalities. Malaria and Schistosoma mansoni co-infection causes exacerbation of health consequences and co-morbidities. The aim of this study was to assess the selected hematological profiles among malaria and S. mansoni co-infected patients at Dembiya Selected Health Institutions. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 140 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz technique were conducted to detect S. mansoni in Stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. A P-value of less than 0.05 was considered statistically significant. Mean of WBC, neutrophil, lymphocyte, eosinophil, RBC, hemoglobin, and hematocrit [4.IU/L,2.2 IU/L, 1.4 IU/L, 0.1 IU/L, 3.13 IU/L, 9.5 g/dL, and 28.7%, resepectively] in co-infected were significantly lower than [7.5 IU/L, 4.6 IU/L, 2.1 IU/L, 0.38 IU/L, 4.8 IU/L, 14.6 g/dL, and 43.7%, resepectively] in the healthy control participants. Mean of RBC, hemoglobin, and hematocrit [3.13 IU/L, 9.5 g/dL, 28.7%, resepectively] in co-infected were significantly lower compared to [3.8 IU/L, 11.5 g/dL, 33.9%, resepectively] in the malaria monoinfected participants and [3.7 IU/L,11.5 g/dL, 33.6%, resepectively] in the S. mansoni monoinfected participants. The result of hematological profiles in healthy participants had no significant difference compared to light,moderate and heavy S. mansoni infection intensity in coinfection. The number of S. mansoni eggs per gram of stool had been negatively correlated with hematological profiles of co-infected participants except lymphocyte and monocyte which correlated positively. Hematological profiles status in coinfection were significantly altered compared to malaria monoinfection, S. mansoni monoinfection, and healthy participants.Therefore, hematological tests should be used to monitor and manage coinfection related complications, and to reduce coinfection associated morbidity and mortality.

Prevalence and Association of Malaria With the Blood Group on Febrile Patients at Woldia Comprehensive Specialized Hospital, Northeast Ethiopia.

Background: Malaria is a disease transmitted by vectors and caused by unicellular Plasmodium parasites. Malaria pathogenesis is associated with the ABO phenotype. However, there is little information on the frequency of malaria disease and its relationship with the ABO blood group in the study area. Therefore, the purpose of this study was to determine the prevalence of malaria infection and its association with the ABO blood group at Woldia Comprehensive Specialized Hospital. Method: An institutional-based cross-sectional study was conducted from December 3, 2022, to February 30, 2023. Convenient sampling was used for selecting the study participants. To identify malaria parasites, thick and thin blood films were made. Additionally, blood was drawn to identify the ABO blood group type. Before being analyzed with SPSS software Version 27, the data was coded and entered into EpiData Version 3.1. To ascertain the variable's association, a logistic regression was done. Results: Out of 192 patients that attended Woldia Comprehensive Specialized Hospital, 16 (8.3%) were found to be infected with Plasmodium parasites using microscopy. Among them, 9 (4.7%), 5 (2.6%), and 2 (1.0%) had Plasmodium falciparum, Plasmodium vivax, or mixed infections, respectively. As a result, 30.7%, 25.5%, 24.5%, and 19.3% of the participants had blood types A, B, AB, and O, respectively (AOR = 2.359, 95% CI: 1.03-12.289, p = 0.03). Conclusion and Recommendation: The total number of microscopically confirmed malaria parasites was 8.3%. P. falciparum was dominant over P. vivax. Individuals with blood group O were less likely to get severe malaria than those with other blood groups. Based on the findings of this study, we recommend that additional studies investigate the probable relationship between the ABO blood group phenotype and malaria infection.

Catheter-associated urinary tract infections in Africa: Systematic review and meta-analysis.

BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) account for the majority of device-associated healthcare-acquired infections with significant morbidity and mortality worldwide. In developing countries with limited resources, the burden of CAUTI have substantial burden owing to the lack of well-organized infection prevention and control. Although there are studies in African countries, the magnitude of CAUTI is inconsistent. Therefore this systematic review and meta-analysis aimed to determine the pooled prevalence of CAUTI in Africa and identify the pathogens involved. METHODS: Systematic review of articles from different databases and search engines such as Medline/PubMed, Google Scholar, Science Direct, and African Journal online were systematically searched to identify potential studies. Data were extracted on Microsoft Excel spreadsheet and analyzed using STATA 17.0. The pooled prevalence of CAUTI was estimated using a random effects model, inverse of variance was used to assess statistical heterogeneity across studies. Egger's tests was performed to identify possible publication bias. RESULTS: This systematic review and meta-analysis incorporated twenty studies, revealing a pooled prevalence of CAUTI at 43.28%. Gram-negative bacteria were the leading cause of CAUTI accounts for 82.9%. Escherichia coli (45.06%) was the most frequent gram-negative bacterial isolate involved in CAUTI followed by Klebsiella spp (24.17%). Staphylococcus aureus was the predominant gram-positive bacterial isolate, accounting for 53.24% of gram-positive associated cases in CAUTI. CONCLUSION AND RECOMMENDATIONS: In conclusion, the high prevalence of CAUTI in Africa underlines a pressing healthcare challenge. Addressing this issue requires a concerted effort, encompassing health education, infection prevention measures, resource allocation, and collaborative initiatives to enhance patient safety and mitigate the impact of CAUTI on healthcare systems in the region. As prolonged catheterization increases the risk of infection, catheters should only be used for proper indications and removed promptly when no longer needed.

Status of selected biochemical and coagulation profiles and platelet count in malaria and malaria-Schistosoma mansoni co-infection among patients attending at Dembiya selected Health Institutions, Northwest Ethiopia.

Malaria and schistosomiasis are infectious diseases that cause coagulation disorders, biochemical abnormalities, and thrombocytopenia. Malaria and Schistosoma mansoni co-infection cause exacerbations of health consequences and co-morbidities.This study aimed to compare the effect of malaria and Schistosoma mansoni co-infection and malaria infection on selected biochemical and coagulation profiles, and platelet count. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 70 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz techniques were conducted to detect Schistosoma mansoni in a stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. An independent t test was used during data analysis. A P-value of less than 0.05 was considered statistically significant. The mean [SD] of alanine aminotransferase, aspartate aminotransferase, creatinine, total bilirubin, and direct bilirubin in the co-infected was higher than in malaria infected participants. However, the mean of total protein and glucose in co-infected was lower than in the malaria infected participants. The mean of prothrombin time, international normalization ratio, and activated partial thromboplastin time in co-infected was significantly higher, while the platelet count was lower compared to malaria infected participants. Biochemical and coagulation profiles, and platelet count status in co-infection were changed compared to malaria infected participants. Therefore, biochemical and coagulation profiles and platelet count tests should be used to monitor and manage co-infection related complications and to reduce co-infection associated morbidity and mortality.

Malaria Prevalence and Risk Factors in Outpatients at Teda Health Center, Northwest Ethiopia: A Cross-Sectional Study.

Background: Despite extensive efforts and achievements made in prevention and control, malaria is still a public health problem in Ethiopia. Currently, the case number has been climbing, even changing the epidemiology to the previously low-burden reporting locations. Therefore, our study is aimed at assessing malaria prevalence and associated risk factors in outpatients, Northwest Ethiopia. Methods: A facility-based cross-sectional study was conducted among 318 malaria-suspected outpatients from October 22 to December 15, 2022, at Teda Health Center, Northwest Ethiopia. Sociodemographic characteristics and malaria risk factors were assessed by a face-to-face interview using a pretested questionnaire. Plasmodium parasites were detected by using microscopy on a blood film stained with 10% and 3% Giemsa stain. The data were analyzed using Statistical Package for Social Sciences software version 25, and statistical significance was reported at a p value < 0.05. Results: Of the 318 study participants, 124 (39.0%; 95%CI = 33.6% - 44.6%) tested positive for Plasmodium infection. Plasmodium vivax, P. falciparum, and mixed infections were identified in 71 (57.3%), 47 (37.9%), and 6 (4.8%), respectively, among positive study participants. Individuals above the age of 15 (AOR = 2.704, 95% CI 1.370-5.336) were more likely to be infected with Plasmodium than under-five-year-old individuals. Rural residents (AOR = 2.56, 95% CI 1.281-5.098), those who sleep or work outside at night (AOR = 1.99, 95% CI 1.020-3.875), and individuals who did not use long-lasting insecticide-treated net (AOR = 3.26, 95% CI 1.633-6.499) and had a family member with a history of malaria (AOR = 2.902, 95%CI = 1.671 - 5.041) had higher odds of acquiring Plasmodium infection than their counterparts. Conclusion: In our study area, malaria was a major health problem, with P. vivax being the dominant species. Multiple environmental and behavioural factors were associated with the infection acquisition. Therefore, urgent holistic intervention is required.

Assessment of abnormal liver function tests and associated factors among COVID-19-infected patients in Addis Ababa, Ethiopia, 2022: a facility-based comparative cross-sectional study.

OBJECTIVE: Liver function test (LFT) abnormalities are higher in patients with severe COVID-19. Most of the studies on this theme were conducted in foreign nations, and the association with LFT abnormalities was not sufficiently addressed in the study areas. Therefore, the current study aimed to investigate the effects of COVID-19 infection on liver function of patients. SETTING: A facility-based comparative cross-sectional study was carried out from 10 April to 15 June 2022, among COVID-19 infected individuals admitted in Eka Kotebe General Hospital and Saint Petrous Specialized Hospitals, Addis Ababa, 2022. PARTICIPANTS: A total of 284 confirmed COVID-19-positive and COVID-19-negative controls matched by gender and age were included in the present study. RESULTS: Among SARS-COV-2 positive groups, 63 (44.4%) had one or more LFT abnormalities. The most common elevated level of the LFTs among patients with COVID-19 were gamma-glutamyl transferase (GGT) 50 (35.2%), while the most common lowered level was albumin 58 (40.8%). The mean values of aspartate aminotransferase (AST) (35.4±26.9 vs 22.9±12.6, p<0.001) were significantly different between patients with COVID-19 and the COVID-19-free groups. Being COVID-19-positive was significantly associated with an elevated level of AST (AOR=3.0, 95% CI 1.2 to 7.4) and GGT (AOR=4.55, 95% CI 2.02 to 10.3). Being male was significantly associated with an elevated level of total bilirubin (BILT, AOR=2.41, 95% CI 1.2 to 4.9) and direct bilirubin (BILD, AOR=3.7, 95% CI 1.72 to 8.2), and also severe stage of COVID-19 was associated with hypoalbuminaemia (AOR=3.3, 95% CI 1.4 to 7.9). SARS-COV-2 infection was independently associated with LFT abnormality. CONCLUSION: Patients with COVID-19 had decreased albumin levels, and elevated AST, GGT, BILT and BILD levels.

Prevalence of pulmonary tuberculosis among key and vulnerable populations in hotspot settings of Ethiopia. A systematic review and meta-analysis.

BACKGROUND: Despite the decline in tuberculosis (TB) incidence across many regions worldwide, including Ethiopia, the disease remains highly concentrated among vulnerable or socially marginalized populations and in high-risk settings. This systematic review and meta-analysis aims to estimate the pooled prevalence of pulmonary tuberculosis (PTB) among key and vulnerable populations (KVPs) residing in hotspot settings in Ethiopia. METHODS: Potential papers were searched systematically in PubMed, Scopus, ScienceDirect databases, Google Scholar search engine, and institutional electronic repositories/registrars. A total of 34 potential articles that provide necessary information on the prevalence of PTB were reviewed and data were analyzed to determine the pooled prevalence of PTB among KVPs. The relevant data were recorded and analyzed using STATA 17.0. Cohen's kappa was computed to determine the agreement between reviewers, the Inverse of variance (I2) to evaluate heterogeneity across studies, and Egger's test to identify publication bias. A random effect model was used to determine the pooled prevalence of PTB, subgroup analysis was computed by types of hotspot settings and year of publication. RESULTS: This meta-analysis demonstrates that the pooled prevalence of PTB among populations residing in hotspot settings in Ethiopia was 11.7% (95% confidence interval (95CI): 7.97-15.43) with an I2 of 99.91% and a p< 0.001. Furthermore, the subgroup analysis unveiled the pooled prevalence of PTB among KVPs residing in different hotspot settings as follows: Prison inmates 8.8% (95CI: 5.00-12.55%), University students 23.1% (95CI: 15.81-30.37%), Refugees 28.4% (95CI: -1.27-58.15%), Homeless peoples 5.8% (95CI: -0.67-12.35%), Healthcare settings 11.1% (95CI: 0.58-21.63%), Spiritual holy water sites attendees 12.3% (95CI: -6.26-30.80%), and other high-risk settings 4.3% (95CI: 0.47-8.09%). Besides, the subgroup analysis revealed that the pooled prevalence of PTB post-2015 was 10.79% (95CI: 5.94-15.64%), whereas it stood at 14.04% (95CI: 10.27-17.82%) before 2015. CONCLUSION: The prevalence of PTB among KVPs residing in the hotspot settings in Ethiopia remains significant, with a weighted pooled prevalence of 11.7%. Thus, the national TB control programs should give due attention and appropriate control measures should be instituted that include regular systematic TB screening, compulsory TB testing for presumptive TB cases among KVPs, and tightened infection control at hotspot settings.

Antimicrobial resistance profile of Pseudomonas aeruginosa clinical isolates from healthcare-associated infections in Ethiopia: A systematic review and meta-analysis.

BACKGROUND: Antimicrobial-resistant (AMR) bacterial infection is a significant global threat to the healthcare systems. Pseudomonas aeruginosa, the leading infectious agent in the healthcare setting is now one of the major threats due to AMR. A comprehensive understanding of the magnitude of AMR, particularly highly public health important pathogens such as P. aeruginosa, is necessary for the management of infections based on local information. OBJECTIVE: This systematic review and meta-analysis aimed to determine the country-wide AMR of P. aeruginosa. METHODS: Systematic searches were performed to retrieve articles from PubMed, Scopus, Web of Science, ScienceDirect electronic databases, Google Scholar search engine, and repository registrars from 2015 to 31st December 2023. Twenty-three studies that provided important data on AMR in P. aeruginosa were systematically reviewed and analyzed to determine the country-wide magnitude of P. aeruginosa AMR profile from healthcare-associated infections. AMR of P. aeruginosa to 10 different antibiotics were extracted separately into Microsoft Excel and analyzed using STATA 17.0. Cohen's kappa was computed to determine the agreement between reviewers, the Inverse of variance (I2) was used to evaluate heterogeneity across studies, and Egger's test to identify publication bias. A random effect model was used to determine the pooled resistance to each antibiotic. Subgroup analysis was performed by infection type and year of publication. RESULTS: This systematic review and meta-analysis revealed that the pooled prevalence of P. aeruginosa in clinical specimens associated with HAI was 4.38%(95%CI: 3.00-5.76). The pooled prevalence of AMR in P. aeruginosa for different antibiotics varies, ranging from 20.9% (95%CI: 6.2-35.8) for amikacin to 98.72% (95%CI: 96.39-101.4) for ceftriaxone. The pooled resistance was higher for ceftriaxone (98.72%), Trimethoprim-sulfamethoxazole (75.41), and amoxicillin-clavulanic acid (91.2). In contrast relatively lower AMR were observed for amikacin (20.9%) and meropenem (28.64%). The pooled multi-drug resistance (MDR) in P. aeruginosa was 80.5% (95%CI: 66.25-93.84). Upon subgroup analysis by infection types and year of publication, P. aeruginosa isolated from healthcare-associated infections exhibited higher resistance to ceftazidime (94.72%) compared to isolates from mixed types of healthcare-associated infections (70.84%) and surgical site infections (57.84%). Antimicrobial resistance in gentamicin was higher during the periods of 2018-2020 (73.96%), while comparatively lower during 2021-2023 (42.69%) and 2015-2017 (29.82%). CONCLUSIONS: Significantly high AMR and MDR were observed from this systematic review and meta-analysis. AMR obtained from this systematic review and meta-analysis urges the need for improved infection control, antimicrobial stewardship practices, and strengthened surveillance systems to control the spread of AMR and ensure effective treatment of P. aeruginosa infections. PROTOCOL REGISTRATION: This systematic review and meta-analysis was registered on PROSPERO (Registration ID: CRD42024518145).
