The degree of inflammation and endothelial dysfunction in treatment of chronic heart failure in patients with coronary artery disease

The purpose of the study was to evaluate the clinico-diagnostic importance of the degree of inflammation and endothelial dysfunction in patients with chronic heart failure (CHF) receiving either standard therapy including ACE inhibitors or the same therapy plus aspirin. One hundred twenty CHF patients aged 45 to 74 were examined. The patients were studied clinically; laboratory tests included measurement of the cerum levels of cytokines with solid-phase immune enzyme assay and serum C-reactive protein (CRP) levels with photometric turbidimetric technique; the vasoregulating function and antithrombogenic activity of vascular wall were evaluated. Improvement in the clinical condition of II to III functional class patients receiving standard therapy was associated with a decrease in pro-inflammatory cytokine and CRP serum levels, as well as a tendency towards improvement in the vasoregulating function and a decrease in the antithrombogenic endothelial activity, mostly due to vascular wall fibrinolytic activity. Standard therapy combined with aspirin led to less prominent changes in the patients' conditions; a simultaneous decrease in the levels of all the cytokines under study was not noted; the vasoregulating activity of the vascular endothelium decreased. The data obtained may be used as additional criteria to objectively evaluate the severity of the condition of CHF patients and to control the effectiveness of the therapy.     

Nosocomial and community acquired uropathogenic isolates of Proteus mirabilis and antimicrobial susceptibility profiles at a university hospital in Sub–Saharan Africa

ObjectiveTo ascertain antimicrobial susceptibility profile of Proteus mirabilis (P. mirabilis) from clinical urine specimens at a university hospital in the spate of its recorded increasing resistance patterns.MethodsThe study was retrospective in nature. Data generated from urine cultures of patients at University of Calabar Teaching Hospital for a period of five years (2004–2009) were compiled. Relevant information obtained were age and gender of patients, organisms recovered and their antibiotic susceptibility patterns. P. mirabilis was identified using standard laboratory procedures.ResultsP. mirabilis showed the highest resistance against ampicillin, cloxacillin, amoxicillin, tetracycline, co-trimoxazole, erythromycin and chloramphenicol (100%–37.2%) while colistin, ofloxacin, ciprofloxacin, ceftriaxone, nalidixic acid and nitrofurantoin recorded the highest activity (59.1%–96.9%) with no drug recording 100% activity. The resistance of the nosocomial isolates of the organism were significantly higher than the community acquired isolates against that of the common antibiotics in use (P<0.05).ConclusionsExtreme caution should be exercised in antibiotic administration in hospital setting and the potential benefits adequately assessed while control of nosocomial infections be given a priority so as to limit the spread of resistant bacteria.     

TLIF术式在布氏杆菌性脊柱炎病人中的临床疗效及安全性分析

目的 对比分析单纯后路内固定+一期经腰椎间孔病椎间病灶清除(TLIF)与经典的前后联合手术在布氏杆菌性脊柱炎患者中的临床疗效及安全性。 方法 对我院2015年1月至2017年12月收治的93例布病性脊柱炎患者的临床资料进行分析。按手术方式分为观察组(45例)和对照组(48例)。对两组患者的基础数据、临床指标、术前术后各项指标水平以及术后并发症、植骨治愈情况。 结果 观察组与对照组基础数据比较,差异无统计学意义(P>0.05)。观察组患者的手术时间、住院天数、术中出血量及术后下床时间均明显低于对照组(P<0.01)。两组患者术后3个月的ODI、VAS、CRP、ESR及Cobb角均明显低于术前(P<0.05);术后3个月,观察组患者的ODI、VAS、CRP、ESR及Cobb角均明显低于对照组(P<0.05)。观察组术后并发症发生率(4.4%)明显低于对照组(25.0%)(Χ²=7.674,P<0.01)。 结论 TLIF治疗布氏杆菌性脊柱炎患者的临床疗效突出,安全性较好,更有利于患者术后身体的恢复。
