Background:  Lower respiratory tract infection is a common cause of morbidity and mortality worldwide. A crosssectional study was carried out with an objective to study the antibiogram of Gram-negative isolates of patients with lower respiratory tract infection visiting Kathmandu Model Hospital.Methods: A total of 274 specimens including sputum, endotracheal aspirates, suction tips were cultured as per standard microbiological technique. Antibiotic susceptibility and detection of Extended-spectrum beta- lactamases (ESBLs) were performed following Clinical Laboratory Standard Institute (CLSI 2014) guidelines.Results: Respiratory pathogens were recovered from 24.6% (n=65) cases. Klebsiella pneumoniae (40%) was the commonest isolates. The highest prevalence of multidrug-resistance (69.23%) was observed in Acinetobacter calcoaceticus baumannii complex. Extended-spectrum beta- lactamases were detected in Escherichia coli (n=4), Klebsiella pneumoniae (n=4) and Acinetobacter calcoaceticus baumannii complex (n=1).Conclusions: High prevalence of multidrug-resistance and extended- spectrum beta- lactamase producers were observed in respiratory isolates. For effective management of lower respiratory tract infections, an ultimate and detailed microbiological diagnosis and susceptibility testing is required.

OBJECTIVES This study was designed with the objectives of describing the distribution pattern of microorganisms responsible for causing LRTI in the workers of garment industries.MATERIALS AND METHODS A total of 198 cases of suspected person of Lower Respiratory Tract infection (LRTI) LRTI were included in this study. This study was conducted between November 2009 to April 2010. Specimen for the study was expectorated sputum. Gram-stain, Ziehl-Neelsen stains and culture were performed.RESULTS On direct microscopic examination, 20.51% were Gram positive bacteria, 79.48% were Gram negative bacteria and 4% were smear positive AFB. On culture sensitivity examination, 22% percent showed growth of different bacteria in different culture media. The bacteria isolated from the samples included Klebsiella pneumoniae (15.38%), Proteus mirabilis (15.38%) and Citrobacterfruendii (15.38%). Gram Negative bacteria were found most susceptible to Ciprofloxacin (92.30%, 24/26) and Amikacin (92.30%, 24/26). Similarly, Gram Positive bacteria were found most susceptible to Ciprofloxacin (100%, 8/8) followed by Cloxacillin and Cephalexin (87.5%, 7/8). Smear positive AFB was significantly associated with not using the protective measures (mask) by workers and presence of symptoms (cough for more than two weeks, night sweat, hemoptysis and anorexia) (p=0.031). Culture positivity was significantly associated with symptoms like production of purulent sputum (p=0.045).CONCLUSION There was insignificant association between LRTI and risk factors present in working room of garment industries. Most of the isolates were sensitive to Ciprofloxacin and resistance to Ampicillin and Cephalexin.Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 14-22

<strong>Objective: </strong>To study drug resistance of pathogenic bacteria in lower respiratory tract infection in patients in Respiratory Department of Internal Medicine. <strong>Method: </strong>On October 2011 to October 2013, there were 112 patients with lower respiratory tract infection in the hospital respiratory medicine ward were reviewed for analysis by collected patient’s infected blood, urine and sputum for laboratory analysis and investigation of drug resistance. <strong>Results: </strong>In a total of 112 strains of pathogenic bacteria, gram negative bacteria, the number of strains was 68, accounting for 60.7% of all strains. The analysis of gram positive bacteria had the lowest drug resistance to vancomycin, but the resistance to erythromycin and penicillin was the highest, while gram negative bacteria were the lowest, but the drug resistance was high. <strong>Conclusion: </strong>In Respiratory Department Of Internal Medicine, patients with lower respiratory tract infection, the pathogenic bacteria which is gram negative bacterial infection is more common, to clarify the distribution of the infection of pathogenic bacteria, and the drug resistance to do a good grasp of the lower respiratory tract infection in patients with lower respiratory tract infection in patients with the role of a thing.

Bronchoalveolar lavage (BAL) is the saline wash of the bronchial tree, which aids in diagnosing various pulmonary pathologies. The present study was contemplated with an aim to know the clinical, microbiological profile of BAL samples along with its sensitivity pattern and to assess its utility as a diagnostic tool. This was a prospective observational study, carried over 90 patients presenting with lower respiratory tract infections. The total microbial recovery rate from BAL was 39 (43.3%). The sensitivity, specificity and positive predictive value of BAL were found to be 76.4%, 89.7% and 90.6% respectively. Maximum isolates were bacteria (25.5%) followed by Mycobacterium tuberculosis (MTB) (16.6%) and fungi (1.1%). Predominant bacterial isolates were Gram-negative (81.5%) compared to Gram-positive (18.5%). Multidrug resistance (MDR) in bacteria was seen in 59.2% of isolates. BAL is a valuable diagnostic tool to find not only bacterial but mycobacterial and fungal infections in patients with lower respiratory tract infection (LRTI). A trend towards LRTI with Gram-negative infections is on the rise and they tend to be multidrug-resistant. Hence checking susceptibility patterns is crucial to start evidence-based treatment.

BackgroundWe developed the chronic obstructive pulmonary disease (COPD)-Lower Respiratory Tract Infection-Visual Analogue Score (c-LRTI-VAS) in order to easily quantify symptoms during exacerbations in patients with COPD. This study aimed to validate this score.MethodsIn our study, patients with stable COPD as well as those with an acute exacerbations of COPD (AECOPD) were included. The results of c-LRTI-VAS were compared with other markers of disease activity (lung function parameters, oxygen saturation and two health related quality of life questionnaires (St Georges Respiratory Questionnaire (SGRQ) and Clinical COPD Questionnaire (CCQ)) and validity, reliability and responsiveness were assessed.ResultsEighty-eight patients with clinically stable COPD and 102 patients who had an AECOPD completed the c-LRTI-VAS questionnaire. When testing on two separate occasions for repeatability, no statistically significant difference between total scores was found 0.143 (SD 5.42) (p=0.826). Internal consistency was high across items (Cronbach’s apha 0.755). Correlation with SGRQ and CCQ total scores was moderate to high. After treatment for hospitalised AECOPD, the mean c-LRTI-VAS total score improved 8.14 points (SD 9.13; p≤0.001).Conclusionsc-LRTI-VAS showed proper validity, responsiveness to change and moderate to high correlation with other questionnaires. It, therefore, appears a reliable tool for symptom measurement during AECOPD.Trial registration numberNCT01232140.

Abstract We sought to examine the influence of clinically severe lower respiratory tract infection on pulmonary artery pressure in children having CHD with post-tricuspid left-to-right shunt, as it may have physiological and clinical implications. In a prospective single-centre observational study, 45 children with post-tricuspid left-to-right shunt and clinically severe lower respiratory tract infection were evaluated during the illness and 2 weeks after its resolution. Pulmonary artery systolic pressure was estimated non-invasively using shunt gradient by echocardiography and systolic blood pressure measured non-invasively. Median pulmonary artery systolic pressure during lower respiratory tract infection was only mildly (although statistically significantly) elevated during lower respiratory tract infection [60 (42–74) versus 53 (40–73) mmHg, (p < 0.0001)]. However, clinically significant change in pulmonary artery systolic pressure defined as the increase of >10 mmHg was present in only 9 (20%) patients. In the absence of hypoxia or acidosis, only a small minority (9%, n = 4) showed significant pulmonary artery systolic pressure rise >10 mmHg. In the absence of hypoxia or acidosis, severe lower respiratory tract infection in patients with acyanotic CHD results in only mild elevation of pulmonary artery systolic pressure in most of the patients.
