RESUMO
Background & objectives: Infections caused by vancomycin-resistant Enterococci are difficult to treat given the limited therapeutic alternatives. Different gene clusters are known to confer vancomycin resistance. vanA and vanB genes are transferable and are clinically relevant. This cross-sectional study aimed to identify the vancomycin-resistant genotypes in the strains causing urinary tract infection and also to test the in vitro efficacy of linezolid and pristinamycin against the vancomycin-resistant isolates. Methods: Antimicrobial resistance profile of 118 enterococcal isolates was evaluated. Minimum inhibitory concentration of vancomycin, teicoplanin and high-level gentamicin (HLG) was determined by micro broth dilution. The vancomycin-resistant isolates were tested against linezolid and pristinamycin by micro-broth dilution and E strip method. The presence of vancomycin-resistant genes was detected by multiplex polymerase chain reaction and was sequenced and analyzed. Results: Most commonly isolated species were Enterococcus faecalis (76.9%) and Enterococcus faecium (16.9%). It was found that 43 per cent of the isolates were resistant to HLG and 16.9 per cent to vancomycin. Higher resistance was seen against fluoroquinolones, erythromycin, tetracycline and ?-lactam drugs. However, 5.08 per cent strains were resistant to tigecycline. All vancomycin-resistant strains were sensitive to pristinamycin and one was resistant to linezolid. vanA and vanB gene were found in 15 and five isolates, respectively. The gene sequences were submitted to NCBI gene bank and accession numbers were obtained. Interpretation & conclusions: The present study showed prevalence of vanA and vanB genes carrying Enterococcus in a tertiary care centre in north India. The emergence of resistance against drugs such as tigecycline and linezolid is a topic of concern as it will be a therapeutic challenge for physicians.
RESUMO
ABSTRACT Background: Co-morbid diabetes and depression are prevalent chronic conditions negatively affecting quality of life (QoL). Inflammation has been considered as an integral mechanism in patients with both diabetes and depression. Objective: The aim of the present study was to investigate depression and its association with interleukins (IL)-1β and IL-9 in type 2 diabetic patients (T2DM) and controls. The QoL in diabetic patient was also assessed. Methods: Eighty subjects were included, distributed among three groups: Group 1 - Healthy controls; Group 2 - T2DM patients without depression; Group 3 - T2DM patients with depression. Depression and QoL were assessed using Patient Health Questionnaire (PHQ-9) and The Audit of Diabetes-Dependent QoL (ADDQoL), respectively. IL-1β and IL-9 were measured in serum samples of all the patients using ELISA kit. Results: The PHQ score in the Group 3 was significantly higher as compared to Group 1. The ADDQoL scores in the Group 3 were significantly higher as compared to Group 2. Levels of IL-9 and IL-1β were elevated in Group 3, as compared to the other groups. Conclusion: This study showed positive association between depression and IL-1β, IL-9 in T2DM patients. Additionally, the diabetic patients have poorer quality of life, which is further worsened by the presence of depression. Thus, routine assessment for the presence of depression is suggested in T2DM patients.
RESUMO Introdução: O diabetes e a depressão comórbidas são condições crônicas prevalentes que afetam negativamente a qualidade de vida (QdV). A inflamação tem sido considerada como um mecanismo integral em pacientes com diabetes e depressão. Objetivo: Investigar a depressão e sua associação com interleucinas (IL)-1β e IL-9 em pacientes diabéticos tipo 2 (DM2) e controles. A QdV em diabéticos também foi avaliada. Métodos: Foram incluídos 80 indivíduos, divididos em três grupos: Grupo 1 - controles saudáveis; Grupo 2 - pacientes com DM2 sem depressão; Grupo 3 - pacientes com DM2 com depressão. A depressão e a QdV foram avaliadas usando o Questionário de Saúde do Paciente (Patient Health Questionnaire - PHQ-9) e a auditoria de QdV dependente de diabetes (Audit of Diabetes-Dependent Quality of Life - ADDQoL), respectivamente. IL-1β e IL-9 foram medidas em amostras de soro de todos os pacientes utilizando kit de ELISA. Resultados: O escore do PHQ no grupo 3 foi significativamente maior em comparação ao grupo 1. Os escores de ADDQoL no grupo 3 foram significativamente maiores em comparação ao grupo 2. Os níveis de IL-9 e IL-1β foram elevados no grupo 3, como em comparação com os outros grupos. Conclusão: Este estudo mostrou associação positiva entre depressão e IL-1β, IL-9 em pacientes com DM2. Além disso, os pacientes diabéticos têm pior QdV, o que é ainda piorado pela presença de depressão. Assim, a avaliação rotineira da presença de depressão é sugerida em pacientes com DM2.
