Bacterial profile, drug resistance pattern, clinical and laboratory predictors of ascites infection in cirrhosis patients.

Ascites is a pathological collection of free fluid in the peritoneal cavity, which is a common complication in patients with cirrhosis, an advanced liver disease. Bacterial infection increases the mortality rate of hospitalized patients with cirrhosis, irrespective of the severity of the liver disease. Around 60% of patients with compensated cirrhosis developed ascites within 10 years during the course of their disease. The in-hospital mortality rate due to spontaneous bacterial peritonitis (SBP) could exceed 90%, but with early diagnosis and prompt antibiotic therapy, this rate has been shown to decrease to 20%. Here, we enrolled adult (age ≥ 18) patients with liver disease with evidence of cirrhosis who developed ascites and assessed the presence of spontaneous ascites fluid infection (SAFI) in these patients. Of the total 218 patients, 22.9% (50/218) develop ascites infection. The liver organ function tests like alanine aminotransferase, aspartate aminotransferase, total bilirubin, and direct bilirubin were found to be significantly (P < 0.05) higher in patients with ascites fluid infection compared to patients with non-ascites fluid infection. Of the gram-negative bacteria, K. pneumonia and E. coli were isolated and found to be 100% resistant to amoxicillin and clavulanate. From the gram-positive bacterial isolates, S. aureus was only resistant to penicillin, whereas Str. viridans was resistant to ceftriaxone, cefotaxime, cefepime, and penicillin. On the other hand, clinical features such as a history of jaundice, low arterial blood pressure, and ultrasound results such as a shrunken liver and enlarged spleen were also independent predictors of spontaneous bacterial peritonitis. In conclusion, given the high probability of death following SAFI, early detection, and treatment, as well as knowledge of the microbial agent, resistance profile, and predictive markers in various contexts, are essential for the timely diagnosis and management of SAFI in these patients.

Phenotypic Drug Resistance Pattern and Mutation Characteristics of Mycobacterium tuberculosis from Different Body Fluids Among Extra Pulmonary Patients Presented in Selected Hospitals in Addis Ababa, Ethiopia.

Background: Drug resistance in tuberculosis poses challenges to both the control and prevention of the disease. The extent of resistance is not well known in developing countries, including Ethiopia. This study was conducted to determine the drug resistance patterns and mutation characteristics of Mycobacterium tuberculosis among extra pulmonary tuberculosis patients in selected health facilities in Addis Ababa. Material and Methods: A cross-sectional study was conducted from February 2022 to August 2022 in selected hospitals in Addis Ababa. Socio-demographic and clinical data were collected using structured questionnaire. Mycobacterium tuberculosis complex (MTBC) isolates were tested for phenotypic drug susceptibility patterns using the Mycobacterium growth indicator tube (MGIT) method for first-line drugs and mutation characteristics using the Line Probe Assay (LPA) method. The data were analyzed using: SPSS version 23, and a P-value ≤ 0.05 was considered statistically significant. Results: From a total of 308 patient samples from presumptive extra pulmonary patients, 44 (14.3%) were positive for MTBC. Any drug resistance was discovered in 25% of 44 MTBC isolates evaluated for five first-line drugs phenotypically, with isoniazid (INH) and pyrazinamide (PZA) resistance accounting for a greater proportion with 13.6% and 11.4% of the isolates, respectively. Two (4.5%) of the isolates were MDR-TB. Out of 44 isolates tested using the Geno Type MTBDRplus assay, 5 (11.4%) showed mutations at katG and 2 (4.5%) showed mutations in the rpoB genes. Conclusion: Both the phenotypic and genotypic drug susceptibility test results showed a high proportion of INH resistance. All INH resistance-conferring mutations were identified from katG gene. The overall prevalence of MDR-TB was also high. For early case detection and treatment, expanding diagnostic capacity for first-line DST is a vital step to limit further spread of drug resistant TB strains in the study area.

Neisseria Gonorrhoae and their antimicrobial susceptibility patterns among symptomatic patients from Gondar town, north West Ethiopia.

Background: Neisseria gonorrhoeae, the causative agent of gonorrhoea, is a Gram negative, coffee-bean shaped facultative intracellular diplococcus bacterium, the classical sexually transmitted bacteria. Nowadays, N. gonorrhoeae has developed high-level resistance to all traditional antimicrobials used for the treatment of gonorrhoea and makes the treatment complicated. So, the aim of this study was to determine magnitude and antimicrobial resistance patterns of N. gonorrhoeae. Methods: A cross sectional study was conducted between April and August 2016 among STI clinic clients in Gondar town hospitals and health centers. Urethral swab and cervical swab specimens were inoculated to Thayer Martin media (OXOID, UK) plates. Observation of Gram-negative intracellular diplococcic was a presumptive diagnosis of gonococcal infection. Finally, antimicrobial susceptibility was assessed by using a modified Kirby-Bauer disk diffusion test, with results indicating susceptible, intermediate or resistant. Data were entered and analyzed using SPSS version 20. Results: The overall prevalence of laboratory confirmed N. gonorrhoeae was 25(20.8%). The isolated N. gonorrhoeae was resistant 100% to tetracycline, penicillin and 80% percent was multidrug resistant. Conclusion: Prevalence and drug resistance of N. gonorrhoeae were high in the study area. A large study is needed in order to know the magnitude in the community as well as to increase awareness of both regional health bureaus and the Ministry of Health about the treatment guide-lines.

Prevalence of Selected Sexually Transmitted Infection (STI) and Associated Factors among Symptomatic Patients Attending Gondar Town Hospitals and Health Centers.

BACKGROUND: Sexually transmitted infection (STI) is a major global cause of acute illness, infertility, long-term disability and death, with serious medical and psychological consequences to millions of men, women and infants. Moreover, in Ethiopia, epidemiological studies on STI among STI clinic clients are limited. Therefore, the aim of this study was to determine the prevalence and associated risk factors of sexually transmitted infection (STI). METHODS: A cross sectional study was conducted between April and August 2014 among STI clinic clients in Gondar Town hospitals and health centers. One hundred twenty study participants who fulfill the criteria were included. Different laboratory methods and techniques were applied to identify the possible microorganisms. Data were entered and analyzed using SPSS version 20. Logistic regression was used to determine risk factors for STI and P values < 0.05 was considered statistically significant. RESULTS: The overall laboratory test confirmed that STIs prevalence was 74.1% with 32.5% being Candida spp., 30% T. palladium, 20.8% N. gonorrhoeae and 14.2% T. vaginalis. Two or more organisms were isolated in 20% of the study subjects. Risk factors for STI had knowledge about STI and alcohol consumption. CONCLUSION: The prevalence of N. gonorrhoeae, T. pallidum, T. vaginalis, and Candida spp. in the study area was high. It needs health education programs, promotes condom utilization and more comprehensive community based STI studies.
