Objective: To compare the efficacy and safety of intravenous and oral levofloxacin versus ceftriaxone and cefixime in treatment of lower respiratory tract infections(LRTI) and urinary tract infections(UTI). Methods:A prospective, randomized, multicenter, comparative study was carried out in LRTI and UTI patients. Patients received either levofloxacin 300 mg twice daily intravenously followed by the same dosage orally or ceftriaxone 2.0 g once daily intravenously followed by oral cefixime 200 mg three times daily for 10-14 days. Results:Two hundred and fourteen patients were enrolled this study, 192 patients were evaluable, 92 in levofloxacin group with 54 cases of LRTI and 38 UTI; 100 patients in ceftriaxone followed by cefixime group with 59 cases of LRTI and 41 UTI. Clinical cure rates and total effective rates were 77.2%(71/92) and 93.5%(86/92) in levofloxacin group, 82.0%(82/100) and 95.0%(95/100) in control group; the bacterial eradication rates being 93.0%(53/57) and 97.1%(66/68) respectively. The clinical adverse effect rates were 16.0%(17/106) and 4.6%(5/108), while abnormal laboratory tests being 12.3%(13/106) and 13.0%(14/108) in the two groups respectively. No significant difference of the above figures between the two groups were found, however, the adverse effect rates in levofloxacin group was higher than that of control group (P=0.012). Conclusions:Levofloxacin sequential therapy is as effective as parenteral ceftriaxone followed by oral cefixime in the treatment of lower respiratory tract infections and urinary tract infections, adverse effects are mild and transient in both groups but more frequent in levofloxacin group than in control group.
To study the clinical features,anfimicrobial resistance,prevention and treatment of pulmonary infection caused by extended spectrum β-lactamase(ESBL)producing Klebsiella pneumoniae and Escherichia coli in elderly pa- tients.Methods 98 elderly patients with pulmonary infection caused by ESBL producing Klebsiella pneumoniae and Es- cheichia coli treated in the Sixth People’s Hospital of Shanghai were enrolled in this study.The clinical features,chest X -ray findings,treatment and outcome of these patients were analyzed so as to understand the charateristics of the infec- tion.Antimicrobial drug susceptability tests for these organisms were carried out and presence of ESBL also tested.Results Fever,cough and expectoration were the main clinical symtoms of the 98 patients and decrease of consciousness found in a portion of them.The main chest X-ray findings of the pulmonary infection due to these two bacteriae were lobar consoli- dation with air containing segmental bronchi,(25% and 3.3%),lobular infiltration(61.8% and 83.3%)and formation of lung abscess or empyema(13.2 % and 3.3 %)Among the patients with Klebsiella infection,9 cases(13.2%)showed the characteristic X-ray finding of interlobar fissure depression.21(30.9%)and 8(26.7%)strains were found to be ESBL producing in each of the groups with the infection.The isolated bacteriae were resistant to many antibiotics,but sus- ceptible to imipenem and compound antibiotics containing β-lactamase inhibitors.Conclusions Elderly patients with pulmonary infection caused by ESBL producing bacteriae may present with loss of appetite,diarrhea,somnolence and de- creased consciousncess.Diagnosis of these infection depends mainly on the isolation of etiologic bacteriae as well as chini- cal and X-ray findings,Imipenem and compound antibiotics containing β-lactamase inhibitors may be used.Measures for preventing nosicimial infection of these bacteriae should be taken.
Objective To evaluate the safety and effectiveness of etimicin sulfate and amikacin sulfate on bacterial infection in lower respiratory tract infection.Methods Using the random,contrast and ope test method,in etimicin sulfate group (n=60) 100 mg in 100 ml NS was intravenously given,twice a day;in amikacin sulfate group (n=60) 400 mg in 500 ml NS was intravenouly given,once a day,with a treatment course of 5~10 days for both groups.Results 30 cases in each group were evaluated for its effectiveness,the effective rates in etimicin sulfate group and in amikacin sulfate group were 90.0% and 86.7% respectively,the clearing bacteria rates were 88.5% and 88.0% respectively.The other 30 cases in each group were evaluated for its safety,the incidences of dys response of deafness were 3.3% and 3.3%,and the incidences of dys response of kidney were 3.3% and 3.3%.There was no significant difference between two group (P0.05).Conclusion Etimicin sulfate is safe and effective in treating bacterial infection in lower respiratory tract.
Objective To learn about the clinical characteristics and the drug resistance of Klebsiella pneumonie induced extensive spectrum β-lactam(ESBL). Methods Analysis of Klebsiella pneumonie lung infection,clinical symptomatology,chest X-ray,treatment and outcomes of 61 elderly patients were made in our department during 2001 to 2002.Drug sensitivity in vitro ESBL detected in 12 antibiotics including amikacin were observed in their activities to the bacterial resistance by in vitro test sensitivity drug with paper testing method for ESBL.Results 94.9% of those patients had underlying diseases and most of them presented fever, productive cough with sputum, X-ray of lobar consolidation (26.2%), lobular infiltration (59.9%) and lung abscess(14.8%) . In ten patients(16.4%) there were the specific X-ray sign,curling down of lobular fissure in Klebsiella pneumonie lung infection.Among the 61 patients, ESBL-positive Klebsiella pneumonie was 31.1%,being cross-resistant to many antibiotics, but were sensitive to imipenem and inhibitor of ESBL compounding antibiotics.Conclusion The elderly patients having Klebsiella pneumonie lung infection usually have underlying diseases with nonspecific clinical features.The diagnosis is mainly made by sputum culture in combination with clinical and radiological examination.In the treatment,one should rely on the drug sensitivity test and choose the the sensitive antibiotics. For ESBL's Klebsiella infection of lung, one should use imipenem or compound antibiotics of ESBL-inhibitor or other sensitive drugs shown by sensitivity test.
Objective:To evaluate the efficacy and safety of dom estic levofloxacin injection and tablet in treating moderate bacterial infectio n.Methods:106 patients with moderate bacterial infection were randomly divided into 2 groups:group A received domestic levofloxacin,iv,drip 200mg bid for (10~)14 days,and group B(sequential therapy group)received levofloxacin,iv, drip 200mg bid for 4 days then followed by levofloxacin tablets 200mg bid orally for 7~10 days.Results:The clinical efficacy rate was 86.79% in group A and 84.91% in group B,while bacterial clearance was 77.78% and 76.00% respectively,without si gnificant difference (P0.05).The adverse reaction incidences were mild and low in both groups.But the cost/efficacy ratio in group B was higher than group A,because of the shorter hospitalization and lower medical expenditure (P0. 01).Conclusion:The domestic levofloxacin was effective and safe in treating moderate bacterial infection.And sequential antibiotic therapy of levofloxacin was more economic in clinical use.
Objective To learn about the clinical characteristics and the drug resistance of Klebsiella Pneumoniae inducing extensive spectrum β lactam(ESBL). Methods 60 patients infected by Klebsiella Pneumoniae in lung were studied depending on clinical data, inculding age, basic diseases, drug usage before infection, the deficiency of immune system, clinical symptoms and signs, the treatment and the prognosis. 34 of 60 (56.7%) were under the test of drug sensitiveness in vitro for ESBL; 26 patients without the test. 16 antibiotics inculding amikacin and ceftazidime were observed their activity to the germ resistance in vitro. Results 95.9% of 60 patients, had basic diseases, mostly chronic obstructive pulmonary disease. These patients presented simptoms of fever, sputum produced cough, X-ray of lobular consolidation in air inflated sign (26.7%); infiltration in lung lobar (58.3%) and lung abscess. 11 (18.3%) patients presented classical X-ray sign of lobular fissure curving down of Klebsiella Pneumoniae lung infection. White blood cell was elevated in 68.3%. of 60 patients. And neutrophil was higher than 81%(61.7%), perhaps due to the rapid development of the infection. 34 of 60 patients tested for ESBL and 11 of them were positive. ESBL negative Klebsiella Pneumoniae and the germ without testing of ESBL were sensitive to amikacin and tobramycin, with sersitivity of 91.3%, 96.2% and 95.7%,96.2%, respectively. Also, the sensitivity to these Klebsiella Pneumoniae was higher than 80% to cefuroxime and cefoxitin, even higher than 90% to ceftazidine, ceftriaxone, and cefoperazone. But resistance of cefuroxime and ceftazidine to ESBL Klebsiella Pneumoniae were 72.7% and 63.6% ; the cross resistance of ESBL Klebsiella Pneumoniae to amikacin and tobramycin was 63.6% and 54.5%; and the resistance to ciprofloxacin and compound sulfamethoxazde as high as 54.5% and 90.9%. All the tested Klebsiella Pneumoniae were sensitive to imipenem or inhibitor of ESBL compounding antibiotics. Conclusion Being diagnose by the culture of Klebsiella Pneumonia and combination of clinical date and X-ray s,lung infection of Klebsiella Pneumoniaepresents unclassical symptoms and basic disease. It can be treated depending on drug sensitive testing and chosing the sensitive antibiotics, especially in combination. But imipenem and compound antibiotics of ESBL-inhibitor or drugs demonstrated by cultrue sensitive to these germs were introduced to treat the lung infection of ESBL Klebsiella Pneumoniae.

Objectives To investigate the effectiveness of PHV combined with low PEEP for severe asthma.Methods 12 severe asthma patients were treated with PHV combined with low PEEP ventilation. Ventilation modewas set as volume control or assistant/control with PHV (PaCO2<10.6 kPa,pH>7.15). 2 of them were treated withSIMV and PEEP. The tidal volume was set as 6 8 mi/kg. PEEP was set at 5~10 cm H2O. Breath frequency wasset at 14 - 16 per minute. FiO2,PIP,ABG,HR, and BP were all recorded. Results Before treatment, 12 patientswere all in the state of respiratory failure and mental confusion, including lethargy and coma with PaO2. 6.18 ± 0.64kPa, pH7.14 ± 0.07 kPa, and PaCO2 10.6 1.53 kPa. After 2 - 8 hours, 24 hours, 48 hours, and 72 hours of PHVcombined with PEEP treatment, pH and PaO2 were all raised remarkbly (P<0.01). However, PaCO2 was loweredstep by step above the normal level in 72 hours. All 12 patients were alive without any complications. ConclusionWith sufficient oxygen support, PHV combined with PEEP may gradually decrease PaCO2 and raise pH to normal lev-el. It has been proved to be an effcctive mechanical ventilation therapy of severe asthma. (Shanghai Med J, 2000,23:491-492)
