RESUMO
Objectives To compare the differences in intestinal phylum firmicutes between elderly patients with type 2 diabetes (T2DM)and the healthy elder people.Methods 37 elderly patients with T2DM and 69 healthy controls in Shaoxin city were recruited.DNA of phylum firmicutes from fecal samples was extracted.The real-time quantitative PCR was used with special primers for bacterial genus including Faecalibacterium prausnitzii,Eubacterium rectale,Clostridium leptum,and Peptostrepyococc.The differences in content of different bacteria between two groups were analyzed and compared.Results In healthy elderly group versus the elder patient with T2DM,the contents of intestinal phylum firmicutes were[(6.22±1.41) × 107 versus(5.41± 1.40) × 107,t=2.83,P=0.006] in Eubacterium rectale,[(7.46 ± 0.98) × 107 versus (6.96 ± 1.40) × 107),t =2.13,P =0.036] in Faecali bacterium prausnitzii,[(7.89±0.89) × 107 versus(7.46±1.11) × 107,t=2.15,P=0.034]in Clostridium leptum,and[(4.86 ± 1.33) × 107 versus (4.21 ± 1.24) × 107,t=2.45,P =0.016] in Peptostrepyococc,which showed that the contents of intestinal phylum firmicutes were less in T2DM group than in healthy elderly group.Conclusions There are some differences in intestinal flora between the elderly patients with T2DM and healthy people.These intestinal flora may play an important role in the development of T2DM.This study may provide new evidences for probiotic treatment of T2DM.
RESUMO
Introducción. La resistencia bacteriana es un problema de salud pública a nivel mundial que compromete seriamente la capacidad de tratar las infecciones. Objetivo. Describir el perfil de resistencia a los antimicrobianos marcadores en enterobacterias identificadas en hospitales colombianos. Materiales y métodos. Se hizo una revisión bibliográfica sistemática de las publicaciones indexadas en Medline, Embase y Lilacs, además de la búsqueda manual de todos los números de revistas colombianas reconocidas en el campo de la infectología y otros afines para identificar referencias no disponibles electrónicamente. Resultados. Se identificaron 43 estudios y reportes de vigilancia epidemiológica con información sobre la resistencia de las enterobacterias en hospitales, principalmente de Bogotá, Cali y Medellín. La tasa de resistencia en Escherchia coli oscila entre 3 y 11 %, 5 y 20 % y 0,2 a 0,8 % para piperacilina-tazobactam, cefalosporinas de tercera generación y carbapenémicos, respectivamente. En aislamientos de Klebsiella pneumoniae , la resistencia oscila entre 21,8 y 48,1 % frente a piperacilina-tazobactam, 20 y 35 % frente a cefalosporinas de amplio espectro y 3 y 8 % frente a carbapenémicos, con variaciones importantes por ciudades, niveles de atención y circunstancias clínicas. Conclusiones. La diseminación de la resistencia bacteriana en enterobacterias aisladas en hospitales colombianos es un problema creciente que requiere medidas prontas para cortar las cadenas de transmisión.
Introduction: Bacterial resistance is a public health problem worldwide that seriously compromises the possibility to treat infections. Objective: To identify levels of resistance to antibiotic markers in Enterobacteriaceae isolates from Colombian hospitals. Materials and methods: A systematic literature survey was done including articles indexed in Medline, Embase and LILACS. A manual search was made of Colombian scientific journals and other publications on infectious disease that were not available electronically. Results: In total, 43 observational studies and epidemiological reports were identified with information about resistance among Enterobacteriaceae isolates in Colombian hospitals, mainly from Bogotá, Cali and Medellín. The resistance rate of Escherichia coli ranges from 3 to 11%, 5 to 20% and from 0.2 to 0.8% for piperacillin-tazobactam, third generation cephalosporins and carbapenems, respectively. For Klebsiella pneumoniae resistance rates ranges from 21.8 to 48.1% to piperacillin-tazobactam, 20 to 35% to broad-spectrum cephalosporins and 3 to 8% to carbapenems, with significant variations by cities, levels of care and clinical settings. Conclusions: The spread of bacterial resistance in Enterobacteriaceae isolated in Colombian hospitals is a growing problem that calls for priority action to cut the chains of transmission.
