Bacterial colonization on the tip of non-tunneled temporary hemodialysis catheters (NTHCs) and associated catheterrelated infections (CRI) is a common complication in hemodialysis (HD) patients. In this study, we aimed to investigate the pattern of bacterial colonization formed on the tip of non-tunneled temporary hemodialysis catheters and their antibiotic sensitivity. Methods: This retrospective analysis was performed in the HD unit of an Education and Research Hospital that follows up a universe of approximately 300 patients, primarily from Mogadishu, Somalia. From September 2020 to September 2021, a total of 137 temporary HD catheters were removed and their tips were sent for culture after there was a suspicion of CRI and other sources of infection were excluded. HD Catheter tips were cultured semi-quantitatively, and the antibiogram of the positive cultures was studied. Results: Gram-positive cocci were found to be the most predominant bacterial organisms in positive cultures with 27 (31.0%) for Staphylococcus aureus, 9 (10.3%) for Staphylococcus haemolyticus and 5 (5.7%) for Staphylococcus epidermidis. We found Enterococci to be 5.7% of the isolated microorganisms. Gram-negative pathogens isolated included Escherichia coli 13 (14.9%) as the most common, followed by Klebsiella pneumoniae 10 (11.5%) and Acinetobacter baumannii (4.6%). Methicillin-resistant Staphylococcus aureus (MRSA) was found to be 9.4%. Gram-positive isolates showed high sensitivity (100%) to Linezolid, Daptomycin, Vancomycin, and Tigecycline, but a low sensitivity rate to Oxacillin (41.2%). Gram-negative isolates had the highest sensitivity to Tigecycline (100%), Imipenem (88.9%), and Amikacin (87%) but low sensitivity to Ampicillin (4.8%), Trimethoprim/ Sulfamethoxazole (TMP-SMX) (23.1%), and Ceftazidime (7.1%). Conclusion:We conclude that each institution should have its own antibiogram in the management of HD CRIs. According to our findings in this study, we recommend intravenous Vancomycin and Imipenem as empirical therapy in patients with suspected HD CRIs.

Background Tuberculosis (TB) is an infectious disease that is the second most common cause of death from a single infectious agent. TB infection affects anyone, regardless of age, gender, and ethnicity. Drug-resistant TB is a serious public health problem, which needs treatment with a second-line anti-TB drug and it includes poly-drug resistance (PDR), multi-drug resistance (MDR), and extensive drug resistance (XDR). The goal of this research is to find out the prevalence of MDR TB among pulmonary TB patients in Banadir, Somalia. Methods This was a multicenter retrospective review of data involving 1732 smear-positive pulmonary TB patients visiting Banadir TB centers between July 1, 2019 and June 30, 2020. Demographic, clinical, and drug susceptibility data were retrieved from TB treatment cards. The data were analyzed using Statistical Package for Social Sciences (SPSS) software (IBM SPSS Statistics version 26). Results All 1732 pulmonary TB cases were previously diagnosed by the Gene Xpert MTB/RIF test. Among them, 70.4% (1219/1732) were males. The mean age was 31.77 years. Overall, the prevalence of drug resistance TB was 10.56% (183/1732). The MDR TB was 1.96%, poly-drug resistance (PDR) was 0.12%, and extensive drug resistance was 0.06%. Conclusion This study showed a prevalence of MDR-TB among pulmonary TB patients, which is similar to some of the eastern African countries.
