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.

Introduction: Lower respiratory tract infection is a major cause of death in children in a developing country and anemia is found to be one of the commonest associated cofactors. This study was aimed to determine association of anemia in children with lower respiratory tract infections.Materials and Methods: The retrospective study was done over a one-year period for children under 5 years of age, admitted in Pediatric Ward of a tertiary Hospital in Lalitpur. The study included 100 diagnosed cases of lower respiratory tract infections as per WHO criteria and 100 age and sex matched patients who did not have respiratory complaints as controls, excluding prematurity, chronic diseases, malnutrition and severe systemic illness. Appropriate clinical history, examination routine investigations like hemoglobin, peripheral smear, and Chest X-ray were included.Results: The age distribution maximum children were in the age group of 3 months to 23 months with significant association with prevalence of both pneumonia (p value 0.005) and anemia (p value 0.002). Anemia was found to be a significant risk factor for LRTI (p value < 0.001) with odds ratio of 2.68 and 95% CI (1.51 – 4.75).Conclusions: Anemia was significantly found to be associated with lower respiratory tract infections and these children were found to be 2.68 times more susceptible to lower respiratory tract infections. Early diagnosis and prevention of anemia is thus important to reduce the incidence of lower respiratory tract infections in children.Nepalese Medical Journal. vol.1, No. 1, 2018, page: 5-8

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

ABSTRACT To study the involvement of cytokines and their corresponding autoantibodies (Aabs) in inflammatory mechanisms in patients with lower respiratory tract infections, blood samples were taken from patients at the time of admission to the hospital and before treatment. Cell-released capturing enzyme-linked immunosorbent assay was used to measure the levels of gamma interferon (IFN-γ) and interleukin-4 (IL-4) produced spontaneously by peripheral mononuclear cells (PMNC). ELISA was used to measure Aabs to these cytokines in sera. The levels of both cytokines were inversely related to the levels of their corresponding Aabs. While a high level of IFN-γ was observed together with a low level of anti-IFN-γ Aab, decreased IL-4 levels were observed with increased levels of Aabs to IL-4. Immunoglobulins were purified, digested to obtain Fab fragments, and tested for specificity and cross-reactivity. The Aabs and their Fab fragments were tested in cytokine biological assays and showed neutralizing effects. Our data demonstrated increased levels of the proinflammatory cytokine IFN-γ and decreased release of the anti-inflammatory cytokine IL-4 during early presentation of lower respiratory tract infection. The levels of these cytokines were inversely related to the levels of their corresponding Aabs that exhibited regulatory effects on the cytokine biological function in vitro.

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.

Background: Decrease in serum sodium concentration is frequent observation among hospitalised elderly patients. The common causes for hyponatremia are degenerative physiology, dehydration, medications and infections. Hence the present study was undertaken to know the extent of hyponatremia among elderly with Lower Respiratory Tract Infections. Objectives: The present study was undertaken to assess the prevalence of hyponatremia in lower respiratory tract infection among geriatric age group and to determine the association between severity of hyponatraemia and LRTI. Methods: This was hospital based cross sectional study carried out in the Department of General Medicine of a tertiary care teaching hospital situated in north Karnataka, India during November 2016 to May 2018. 100 elderly patients (age e” 60 years) with history of cough for more than four to five days, clinical findings and X-ray findings suggestive of LRTI, were selected for the study. Results: In the present study 59% comprised of male whereas females constituted 41%. The prevalence of hyponatraemia among elderly patients with LRTI was 45%. The most common cause of hyponatraemia was GI loss (vomiting) 53.33%, Euvolemic hyponatramia 51.11%. The mean age was 69.99±8.44 years. Most of the patients were aged between 61 to 70 years. .Hyponatraemia was not associated with sex, age and type of LRTI. Duration of hospital stay was significantly longer in patients with hyponatraemia compared to those who did not develop hyponatraemia. Conclusion: Hyponatraemia among elderly individuals with LRTI is higher as compared to other age group hence leading to prolonged duration of hospitalisation.

Abstract Background Influenza is associated with excess morbidity and mortality of individuals each year. Few therapies exist for treatment of influenza infection, and each require initiation as early as possible in the course of infection, making efficacy difficult to estimate in the hospitalized patient with lower respiratory tract infection. Using causal machine learning methods, we re-analyze data from a randomized trial of oseltamivir versus standard of care aimed at reducing clinical failure in hospitalized patients with lower respiratory tract infection during the influenza season. Methods This was a secondary analysis of the Rapid Empiric Treatment with Oseltamivir Study (RETOS). Conditional average treatment effects (CATE) and 95% confidence intervals were computed from causal forest including 85 clinical and demographic variables. RETOS was a multicenter, randomized, unblinded, trial of adult patients hospitalized with lower respiratory tract infections in Kentucky from 2009 through 2012. Adult hospitalized patients with lower respiratory tract infection were randomized to standard of care or standard of care plus oseltamivir as early as possible after hospital admission but within 24 h of enrollment. After randomization, oseltamivir was initiated in the treatment arm per package insert. The primary outcome was clinical failure, a composite measure including failure to reach clinical improvement within 7 days, transfer to intensive care 24 h after admission, or rehospitalization or death within 30 days. Results A total of 691 hospitalized patients with lower respiratory tract infections were included in the study. The only subgroup of patients with a statistically significant CATE was those with laboratory-confirmed influenza infection with a 26% lower risk of clinical failure when treated with oseltamivir (95% CI 3.2–48.0%). Conclusions This study suggests that addition of oseltamivir to standard of care may decrease clinical failure in hospitalized patients with influenza-associated lower respiratory tract infection versus standard of care alone. These results are supportive of current recommendations to initiate antiviral treatment in hospitalized patients with confirmed or suspected influenza as soon as possible after admission.

Background: Frequency of nutritional rickets, its clinicobiochemical profile and its relationship to the lower respiratory tract infections in indoor patients from 2 to 60 months of age.Methods: Children aged 2 to 60 months admitted for the first time were included in the study and divided into two groups i.e. with and without clinical signs of rickets. Disease profile was studied in both groups. Incidence of lower respiratory tract infection was compared between two groups.  Children with clinicoradiological signs of rickets were also investigated for biochemical abnormalities.Results: During the one year study period a total of 393 children were admitted, 65 were found to have rickets constituted as study group and 328 were without rickets were included the controls. Rickets incidence was 16.5% of which majority (74.6%) were males and most rachitic children (64.6%) were below six months of age. Acute lower respiratory tract infection (64.6%) was commonest in study group and acute gastroenteritis (24.4%) in the controls. The rate of ALRTI was nearly three times in study group.  Frontal bossing (67.7%) was most common sign of rickets and increased alkaline phosphatase (93.8%) was the commonest biochemical abnormality.Conclusions: Nutritional rickets, a multifactorial disease, is easily preventable. The present study has revealed the high incidence of rickets i. e., 16.5% and also show the strong statistically significant association of nutritional rickets with acute lower respiratory tract infections.
