BackgroundThe impact of antimicrobial resistance on clinical outcomes in patients with lower respiratory tract infection in primary care is largely unknown.AimTo determine the illness course of infections with resistant bacteria in adults presenting to primary care with acute cough.Design and settingSecondary analysis of a multicentre European trial in primary care.MethodA total of 2061 adults with acute cough (lasting ≤28 days) were recruited from primary care and randomised to amoxicillin or placebo. To reflect the natural course of disease, only patients in the placebo group (n = 1021) were eligible. Nasopharyngeal flocked swabs and/or sputa (when available) were analysed at baseline and Streptococcus pneumoniae and Haemophilus influenzae isolates underwent susceptibility testing. Patients recorded their symptoms in a diary every day for 4 weeks. Patients with and without resistant bacterial infection were compared with regards to symptom severity, duration of symptoms, worsening of illness, and duration of interference with normal activities or work.ResultsOf the 834 patients with diary records, 104 showed S. pneumoniae and/or H. influenzae infection. Of this number, 54 (52%) were resistant to antibiotics, while seven (7%) were resistant to penicillin. For the duration of symptoms rated ‘moderately bad or worse’ (hazard ratio 1.27, 95% confidence interval [CI] = 0.67 to 2.44), mean symptom severity (difference −0.48, 95% CI = −1.17 to 0.21), and worsening of illness (odds ratio 0.31, 95% CI = 0.07 to 1.41), there was no statistically significant difference between the antibiotic-resistant and antibiotic-sensitive groups.ConclusionThe illness course of antibiotic-resistant lower respiratory tract infection does not differ from that caused by antibiotic-sensitive bacteria.

Lower Respiratory Tract Infection (LRTI) is associated with mortality and prolonged antibiotics use among HIV/AIDS patients. Sputum samples were collected from 134 HIV/AIDS patients with LRTI and productive cough, visiting University of Abuja Teaching Hospital, Nigeria, to determine the bacterial aetiologies and antibiotic resistance profile. Adequate for culture sputum samples were observed in only 119 subjects (75 females and 44 males) and cultured using standard procedure. Isolates were identified by biochemical method and 16SrRNA gene amplification, purification, sequencing and database nucleotide blast. Antibiotic susceptibility tests were performed and interpreted according to Clinical and Laboratory Standard Institute (CLSI) procedures. Bacteria associated LRTI was found in 20.2% of the patients and Klebsiella pneumonia (29.7%); Enterobacter cloacae (16.7%); Enterobacter hormaechei subsp. xiangfangensis (12.5%); Pseudomonas parafulva; Pseudomonas aeruginosa; Pseudomonas alcaliphila; Klebsiella aerogenes (8.3%); Comamonas testosteroni; Escherichia coli; Acinetobacter junii; Acinetobacter soli and Acinetobacter baumannii were implicated. Isolates show high resistance to amoxicillin-clavulanic acid at 94.1%, trimethoprim-sulfamethoxazole at 75.0% and cefotaxime at 70.0%. The Multiple Antibiotic Resistance (MAR) index of most isolates (62.5%) is within 0.3-0.8 in a range of 0.0 to 0.8. Isolates of the same species were found to have different MAR index in different patients. However, E. cloacae, E. hormaechei subsp. xiangfangensis, A. baumanni and 71.4% of K. pneumonia were Multi-drug Resistant (MDR). Interestingly, Gentamycin, Ciprofloxacin and Imipenem were effective against MDR isolates and showed significant negative correlation with MAR index. We propose that antibiotics with efficacy against MDR isolates could be used to down regulate the selective pressure of other antibiotics, and these MDR pathogens, including those rarely associated with human infection poses potential threat, similar to Methicillin Resistant Staphylococcus aureus (MRSA). Particularly, among the immunocompromised. Furthermore, HIV/AIDS patients present good metrics for profiling the burden and spread of antibiotic resistant bacteria in poor countries.

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.
