Background: Empirical antibiotics among outpatients with Lower Respiratory Tract Infections (LRTIs) are scarcely allocated in Indonesia. The study aims to evaluate the pathogens causing LRTIs, drug sensitivity test and the minimum inhibitory concentrations of 90% (MIC90) of Cefditoren, Azithromycin, Amoxicillin-Clavulanic Acid, and Cefixime Methods: The study was performed in adult outpatients with LRTI that can be expectorated. Patients with diabetes mellitus, HIV, lung tuberculosis, renal or hepatic failure, and hemoptysis were excluded. We performed bacterial culture, antibiotic sensitivity, and MIC measurement of four antibiotics. Results: There were 126 patients with LRTIs, and 61 patients were eligible for the study. We identified 69 bacteria. We found Klebsiella pneumonia (n=16; 26.23%), Staphylococcus aureus (n=11; 18%), Pseudomonas aeruginosa (n=8; 13.11%), Acinetobacter baumanii complex (n= 4; 6.55%), Streptococcus pneumonia (n=3; 4.9%) and others bacteria as causa of LRTI. Testing MIC90 of Cefditoren and three empiric antibiotics on LRTI found that Cefditoren has a lower MIC of 90 for K. pneumonia (0.97(2.04) µg.mL-1) and S. pneumonia (0.06(0.00)µg.mL-1) than other antibiotics, but almost the same as Cefixime ((0.05(0.16)µg.mL-1) and (0.38(0.17)µg.mL-1). MIC90 Cefditoren for S.aureus (3.18(3.54)µg.mL-1) and P.aeruginosa (9.2(3.53)µg.mL-1) is lower than Cefixime but higher than Azithromycin and Amoxicillin-Clavulanic acid. Reference data MIC90 of Cefditoren for LRTI bacteria is lower than the other three oral empirical antibiotics. Conclusions: In vitro studies of an outpatient LRTI in Surabaya found gram-negative bacteria dominant. Cefditoren can inhibit K.pneumonia and S.pneumonia has lower MIC90 compared to other antibiotics. Cefditoren can inhibit gram-negative and positive bacteria causing LRTI.

BACKGROUND The term tracheostomy refers to forming an opening in the trachea.1,2 Its advantages include easy and direct access to lower respiratory tract, reduced risk of aspiration, faster weaning from ventilation support and improved physical and psychological comfort. But a common problem in tracheostomised patients is increased risk of colonisation of lower respiratory tract by exogenous bacteria because of direct exposure.1,3 This study was done to recognise pathogens in tracheal secretions collected from tracheostomised patients and their antibiotic sensitivity to treat them with appropriate antibiotics. METHODS This prospective study was done in 138 tracheostomised patients from October 2020 to March 2021 in intensive care unit (ICU) of Chettinad Hospital and Research Institute. Under sterile aseptic precautions, Day 0 and Day 7 cultures posttracheostomy was obtained and their antibiotic sensitivity was studied. Data was analysed using Statistical Package for Social Sciences (SPSS version 19) and presented in proportion, mean and standard deviation (Descriptive statistics). RESULTS In this study, of the 56 cases who had growth in their culture and sensitivity reports on day 0, the most common organism was Pseudomonas aeruginosa (33.9 %) sensitive to imipenem (94.7 %) followed by klebsiella (25 %) sensitive to teicoplanin, vancomycin, amikacin, cefoperazone/tazobactam, linezolid and piperacillin/tazobactam. On day 7, the growth of organisms isolated in tracheal culture got reduced from 56 cases to 16 cases. The prevalence of Pseudomonas reduced to 18.8 % in day 7 whereas Klebsiella pneumonia and Acinetobacter remained almost same from day 0 to day 7. CONCLUSIONS This study concludes the predominant pathogen as Pseudomonas aeruginosa with sensitivity to imipenem followed by Klebsiella with sensitivity to teicoplanin, vancomycin, amikacin, cefoperazone/tazobactam, linezolid and piperacillin/tazobactam on day 0 with reduction in the number of organisms on day 7 due to the fact that all our patients were admitted in ICU several days prior to tracheostomy and were started on antibiotics soon after admission as per choice of the treating physician. Hence, a clear understanding of bacterial colonisation post tracheostomy and its change in course is essential for timely intervention with empirical antibiotics for reducing the incidence of lower respiratory tract infections after tracheostomy in future.

This randomized, multicentre, comparative study evaluated the efficacy and safety of treatment with cefuroxime–sulbactam compared with amoxicillin–clavulanic acid (co-amoxiclav) in patients with lower respiratory tract infections (LRTIs). The study enrolled 75 adult inpatients with moderate to severe LRTIs. Patients were treated intravenously for 7 − 10 days. The treatment groups were comparable at baseline with respect to demographic and disease characteristics. Efficacy was evaluated in 72 patients. The clinical success rate was statistically superior in patients treated with cefuroxime–sulbactam (100%) compared with patients treated with amoxicillin–clavulanic acid (88%). The bacteriological success rate was 95% and 100% for cefuroxime–sulbactam and amoxicillin–clavulanic acid, respectively, with no significant difference between treatments. Both treatments were safe and well tolerated. One patient in the cefuroxime–sulbactam group reported convulsions, which the investigator considered were probably not related to the study medication. Cefuroxime–sulbactam can be an effective alternative empirical treatment for LRTIs.

Amoxicillin/clavulanic acid (ACA) is one of the drugs of choice for treatment of lower respiratory tract infections (LRTI) in adults. One of the serious disadvantages of ACA is relatively high rate of gastrointestinal adverse events (AE). A new form of ACA, which is dispersable tablets Solutab, could potentially reduce the rate of AE because of more rapid and predictable absorption of clavulanic acid from intestine and improve clinical outcomes due to higher adherence to treatment. This trial was aimed to compare AE rate and clinical efficacy of the new dispersable ACA form Solutab with those of traditional ACA tabs in adult patients with non-severe LRTI. The treatment regimen comprised 500/125 mg t.i.d. during 5 to12 days. This was an open, prospective randomized trial performed at 4 clinical centres. Adults with clinically and radiologically detected non-severe community-acquired pneumonia or I or II types COPD exacerbations with purulent sputum received dispersable ACA tablets (the 1st group) or traditional coated tabs of ACA (the 2nd group) in a random proportion of 1 : 1. Clinical efficacy was evaluated with clinical signs, physical symptoms, additional laboratory and instrumental testing. The safety was assessed based on the patient's complaints and results of physical and laboratory examination in visits 2 (Day 3 or 4), 3 (Day 5 to 12), and 4 (Day 30 to 40 after taking the first dose of the drug). The trial involved 200 patients, the mean age, 32.7 ± 18.7 and 33.3 ± 18.6 yrs in the 1st and the 2nd groups, respectively. The groups were similar for history, severity, and clinical course of the disease. Clinical efficacy was 96.9 % in both groups in visit 3, 95.9 % and 96.9 % in the 1st and the 2nd group, respectively, in visit 4. The mean duration of antibacterial therapy was 7.1 ± 1.5 days in the 1st group and 7.2 ± 1.4 days in the 2nd group. AE were reported in 15 % and 31 % of the patients, respectively (p = 0.01). Gastrointestinal AE predominated in both the groups but the rate of diarrhea was lower in patients receiving dispersable ACA: 6 % vs. 17 % in the 2nd group (p = 0.027). Therefore, the new dispersable drug form of ACA has better safety profile in adult patients with non-severe LRTI compared to traditional ACA that was demonstrated by reduction in the AE, mainly diarrhea, rate. Both drug forms showed equally high clinical efficacy.

Patients with lower respiratory tract infections [pneumonia ( n = 16), bronchiectasis ( n = 5) and acute exacerbations of chronic bronchitis ( n = 44)] were treated daily with amoxycillin/clavulanic acid given either 1.2 g intravenously three times daily or 625 mg orally three times daily for 7–15 days. Symptoms, signs and sputum volume and colour were monitored daily. Chest X-ray, sputum culture and Gram-stain examinations were also carried out on days 1 and 5, and immediately after the end of the treatment. There was a clinical improvement, as indicated by the incidence of cough, dyspnoea and rales, and by sputum volume and colour in 90.8% of the patients. Microbiological improvement, as indicated by the complete elimination of sputum pathogens and pus cells, was achieved in the same proportion of patients (90.8%). In one patient, an adverse side-effect, diffuse exanthema, was noted. Amoxycillin/clavulanic acid possesses a high clinical and microbiological efficacy for lower respiratory tract infections.

Abstract: Introduction: Glucose non-fermenting Gram-negative bacteria are ubiquitous environmental organisms. Most of them are identified as opportunistic, nosocomial pathogens in patients. Uncommon species are identified accurately, mainly due to the introduction of matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF MS) in clinical microbiology practice. Most of these uncommon non-fermenting rods are isolated from lower respiratory tract samples. Their significance in lower respiratory tract infections, such as rules of their testing are not clarified yet. Aim: The aim of this study was to review the clinical microbiological features of these bacteria, especially their roles in lower respiratory tract infections and antibiotic treatment options. Method: Lower respiratory tract samples of 3589 patients collected in a four-year period (2013–2016) were analyzed retrospectively at Semmelweis University (Budapest, Hungary). Identification of bacteria was performed by MALDI-TOF MS, the antibiotic susceptibility was tested by disk diffusion method. Results: Stenotrophomonas maltophilia was revealed to be the second, whereas Acinetobacter baumannii the third most common non-fermenting rod in lower respiratory tract samples, behind the most common Pseudomonas aeruginosa. The total number of uncommon non-fermenting Gram-negative isolates was 742. Twenty-three percent of isolates were Achromobacter xylosoxidans. Beside Chryseobacterium, Rhizobium, Delftia, Elizabethkingia, Ralstonia and Ochrobactrum species, and few other uncommon species were identified among our isolates. The accurate identification of this species is obligatory, while most of them show intrinsic resistance to aminoglycosides. Resistance to ceftazidime, cefepime, piperacillin-tazobactam and carbapenems was frequently observed also. Conclusions: Ciprofloxacin, levofloxacin and trimethoprim-sulfamethoxazole were found to be the most effective antibiotic agents. Orv Hetil. 2018; 159(1): 23–30.
