类鼻疽三例临床特点分析

Objective To investigate the clinical features of 3 cases of Burkholderia pseudomallei septicemia in Guangxi Province.and therefore to improve its diagnosis and treatment. Method The clinical features.treatment and prognosis of 3 cases of acute septicemic melioidosis admitted to this hospital from October 2006 to December 2008 were retrospectively analyzed. Results The 3 male patients were local farmers,with an average age of (42 ±2)years.Two of them had a history of frequent trauma and contact with polluted water.and another had a history of exposure to the dust and soil.All patients had an acute onset,manifested as septicemia with chills,high-grade fever,anemia and weight loss.At the same time,the disease was often complicated with multiple organ abscesses.The pus wag characterized by smelling like mud.One case wag manifestated with lung abscess.with right calf skin pyogenic infection,and the another case was with liver,spleen,pancreas and mediastinal abscess,and the third presented with right facial and ankle soft tissue abscess.The leukocyte counts[(11.6 ±0.5)×10~9/L]and neutrophils[(8.3±0.4)×10~9/L] in 2 patients were slightly increased,but decreased in the other patient.There were significant increase of erythrocyte sedimentation rate(63.5±2.7)mm/1 h and c-reactive protein (155 ±4)mg/L,and liver dysfunotion and elevated blood glucose occurred in 3 patients.Chest radiology and CT showed a number of patchy infiltrates,consolidation,and nodules with varying sizes in the upper lung lobes.Abscess in other organs mainly occurred in liver,spleen.and skin.The final diagnosis was confirmed as infection with Burkholderia pseudomallei by repeated blood or pus culture.The isolated Burkholderia pseudonmallei wag sensitive to carbapenem,and β-lactam+β-lactamage inhibitors.One patient was treated effectively with Imipenem,and other 2 patients with β-lactam+β-lactamage inhibitors.After 3-4 days of treatment with antibiotics,the body temperature of these patients gradually decreased,and the intravenous drug wag used as long as 4 to 8 weeks.and a total course of antibiotic therapy would continue for 4 to 6 months. Conclusions Human melioidosis exists in the south and southwest of Guangxi.Repeated blood or pus culture can confirm the diagnosis.A relatively long course of antibiotic treatment with β-lactam/β-lactamage inibitors or carbapenem is recommended.
