Pneumonia is a worldwide, serious threat to health and an enormous socio-economic burden for health care system. Community-acquired pneumonia (CAP) is associated with a significant mortality and morbidity. Knowledge of predominant microbial patterns in CAP constitutes the basis for initial decisions about empirical antimicrobial treatment. The aim of this study was to identify the bacterial etiology of CAP in adult hospitalized patients and to see their antibiotic sensitivity pattern. It was a hospital based cross sectional observational study on 87 hospitalized patients diagnosed with CAP admitted in Medicine department of Chittagong Medical College Hospital (CMCH). Sputum for Gram staining, Z N staining, culture sensitivity, blood culture and sensitivity and PCR for Legionella pneumophila, Mycoplasma pneumoniae, Chlamydophila pneumonia and Streptococcus pneumonia were done. Patients were followed up for in-hospital outcome and 30-day mortality. The mean (±SD) age was 49.59±16.97 years and male female ratio was 1.56:1. Sputum culture, blood culture and PCR were positive in 60.9%, 1.1% and 4.6% of the samples respectively. Klebsiella pneumoniae was identified in the sputum culture of the majority of the patients (39.1%), followed by Pseudomonas aeruginosa (10.3%), Staphylococcus aureus and Escherichia coli (5.7%). The only one sample which was positive in blood culture and it was Staphylococcus aureus. Streptococcus pneumoniae was identified in all the 4 PCR positive cases. The highly sensitive drugs were meropenem, levofloxacin and amikacin. In hospital mortality and 30-day mortality was 6.9% and 16.1% respectively. Gram-negative bacteria pre-dominate in the bacteriologic profile of CAP using conventional sputum and blood culture. There is need for further conventional serologic tests for atypical and viral pathogens in all patients admitted with CAP.

Abstract Pneumonia is a worldwide, serious threat to health and an enormous socio-economic burden for health care system. Community-acquired pneumonia (CAP) is associated with a significant mortality and morbidity. Knowledge of predominant microbial patterns in CAP constitutes the basis for initial decisions about empirical antimicrobial treatment. The aim of this study was to identify the bacterial etiology of CAP in adult hospitalized patients and to see their antibiotic sensitivity pattern as well as to observe their clinical profile and short term outcome. It was a hospital based prospective observational study. A total of 87 hospitalized patients diagnosed with CAP were enrolled consecutively from the medicine ward of Chittagong Medical College Hospital (CMCH). Sputum for Gram staining, Z N staining, culture sensitivity, blood culture and sensitivity and PCR for Legionella pneumophila, Mycoplasma pneumoniae, Chlamydophila pneumonia and Streptococcus pneumonia were done. Patients were followed up for in-hospital outcome and 30-day mortality. The mean (±SD) age was 49.59±16.97 years and male female ratio was 1.56:1. Fever, chest pain and cough were the most common clinical features. Sputum culture, blood culture and PCR were positive in 60.9%, 1.1% and 4.6% of the samples respectively. Klebsiella pneumoniae was identified in the sputum culture of the majority of the patients (39.1%), followed by Pseudomonas aeruginosa (10.3%), Staphylococcus aureus and Escherichia coli (5.7%). The only one sample which was positive in blood culture and it was Staphylococcus aureus. Streptococcus pneumoniae was identified in all the 4 PCR positive cases. The highly sensitive drugs were meropenem, levofloxacin and amikacin. The mean (±SD) duration of hospital stay was 6.34±2.37. In hospital mortality and 30-day mortality was 6.9% and 16.1% respectively. Gram-negative bacteria pre-dominate in the bacteriologic profile of CAP using conventional sputum and blood culture. There is need for further conventional serologic tests for atypical and viral pathogens in all patients admitted with CAP.

Background: Diabetes mellitus (DM) is an immunosuppressive condition and uncontrolled diabetes is associated with increased susceptibility to various infections like pneumonia. Community acquired pneumonia (CAP) in diabetic patients is often caused by more virulent or atypical organisms and associated with increased resistance to conventional antibiotics. The aims of this study were to identify the bacterial etiology of CAP in patients with DM and to see their antibiotic sensitivity pattern.Methods: This was a cross-sectional, observational study conducted in the Department of Internal Medicine & Pulmonology of BIRDEM General Hospital, Dhaka, Bangladesh, from January 2013 to December 2015. A total of 120 hospitalized diabetic patients diagnosed with CAP and with a positive sputum culture growth of any bacteria were included in the study.Results: Majority (67%) of the patients were male. Mean age of the patients was - 55.69 ±10.5 years. Mean duration of diabetes was - 7.35 ±1.3 years. Mean HbA1c was - 8.6 ±1.89%. Sputum for culture showed that out of 120 (100%) patients, Klebsiella pneumoniae was detected in 53 (44.2%) patients, Staphylococcus aureus in 18 (15.0%), Pseudomonas species in 16 (13.3%) patients, Acinetobacter in 10 (8.3%), Escherichia coli in 9 (7.5%) patients and 14 (11.7%) patients had growth of other organisms. Sensitivity pattern of different bacterial growth in sputum to commonly used antibiotics like ceftriaxone, ciprofloxacin, amikacin and imipenem were as follows – Klebsiella (19%, 47%, 74%, 96% respectively), Staph aureus (11%, 33%, 78%, 67% respectively), Pseudomonas (19%, 75%, 81%, 88% respectively), Acinetobacter (0%, 0%, 20%, 50% respectively), E. coli (22%, 22%, 100%, 100% respectively). All (100%) of the Pseudomonas and Acinetobacter were sensitive to colistin. Most of the growth of all the bacteria (Klebsiella 94%, Staphylococcus 78%, Pseudomonas 81%, Acinetobacter 100%, E. coli 100%) occurred in patients with poor glycemic control (HbA1c ? 7.0%).Conclusion: This study results suggest that CAP in diabetic patients are more frequently due to Klebsiella pneumoniae, Staphylococcus aureus and Pseudomonas species and mostly they are less sensitive to commonly used antibiotics like ceftriaxone and ciprofloxacin. So, whenever possible, treatment of CAP should be guided by sputum culture and sensitivity test and for empirical treatment of CAP in diabetic patients, alternative antibiotics like imipenem and amikacin should be considered.Birdem Med J 2017; 7(2): 101-105

Urosepsis usually develops from a community or nosocomial acquired urinary tract infection (UTI) or during the procedure of various urinary disease such ureterorenoscopy (URS) and percutaneous nephrolithotomy (PCNL). Urosepsis is associated with bacteriuria, Urosepsis due to manipulation during or after percuteneous nephrolithotomy (PCNL) or ureterorenoscopy (URS) or push bang stenting can be catastrophic despite prophylactie antibiotic coverage. This cross sectional study was carried out in Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2011 to June 2013. Sampling technique was purposive and sample size was 70. Among them 23 patients for PCNL and 47 patients for URS were selected by selection criteria. Data were collected by interview of the patients, clinical examinations and laboratory investigations using the research instrument. Data were processed and analyzed using software SPSS (Statistical Package for Social Sciences) version 11.5. Incidence of bacteriuria and urosepsis were measured according to urine and blood culture report. Sensitivity pattern was also observed. According to this study, the incidence of bacteriuria and urosepsis were 17.1% and 5.7% respectively, Of the 70 patients, 12(17.1%) exhibited bacterial growth on urine culture, These 12 patients were then subjected to blood culture and 4(33.3%) of them were found positive. Most (83.4%) of the urine and blood infections (75%) were caused by E. coli. Some widely used antibiotics like moxicillin, Cephalexin and Ciprofloxacin were found 100% resistant in urine culture. Few sensitive antibiotics were Tobramycin (100 %), Amikacin and Ceftazidime (75%). Almost same sensitivity pattern was found in blood culture. In urosepsis, as in other types of sepsis. Urosepsis after PCNL and URS is an important and potentially catastrophic complication. Percuteneous nephrolithotomy (PCNL), Ureterorenoscopy (URS) occurs frequently in this institution. Although the incidence of urosepsis and bacteriuria with resistant organism is low, but it is a burning issue in management in urology practice. The apparent increase in ciprofloxacin resistant organisms appears to be associated with the increased rate of ciprofloxacin resistant organisms are observed in the general population.

A cross sectional descriptive study was done to find out the causative organisms and their antibiotic sensitivities in the Department of Microbiology in collaboration with the Department of Paediatrics, Rajshahi Medical College Hospital (RMCH), Rajshahi during the period of July 2014 to June 2015. A total of 116 blood samples were taken aseptically from patients who were suspected of neonatal septicemia. Blood was then inoculated in Brain heart infusion broth. Bacterial isolation, identification and antimicrobial susceptibility testing were done by standard microbiological methods. Among 116 cases, 33(28.4%) were found to be culture positive. The most commonly isolated causative agents of neonatal septicemia were Staphylococcus aureus 17(51.5%) followed by Escherichia coli 10(30.3%), Streptococcus pneumoniae 03(9.09%), Klebsiella pneumoniae 02(6.06%) and Pseudomonas aeruginosa 01(3.03%). In general, all the Gram positive and Gram negative isolates were highly sensitive to meropenem, amikacin, gentamicin and ciprofloxacin. Gram positive bacteria were found to be particularly sensitive to vancomycin. They were moderately sensitive to ceftazidime followed in amoxicillin but were totally resistant to ampicillin. This study revealed that Staphylococcus aureus and E.coli are predominant causative organisms in neonatal septicemia and these are highly sensitive to meropenem, amikacin, gentamicin and ciprofloxacin.Faridpur Med.

Background: The moment most common cause of in-hospital infection is pneumonia. Pneumonia is prevalent within the ICU (Intensive Care Unit) setting and can be deadly. The Incidence of pneumonia is approximately 17% in the therapeutic ICU2 but can be 6 to 20 times increased in mechanically ventilated patients. The duration of hospital stay and expenditure are both expanded in patients who develop ventilator-associated pneumonia. This study aims to identify the causative microorganism responsible for CAP (Community-Acquired Pneumonia) and VAP (Ventilator-Associated Pneumonia) and their antibiotic sensitivity pattern. Methods: This was a comparative cross-sectional study that was carried out at two ICU in Sylhet city. The data was collected from the patient's medical information, the patient's file, and the hospital information system. Culture and sensitivity (C/S) were collected from the electronic medical information system (MIS). All data from January 2019 to December 2020, including patient's information, course of the disease (in terms of death or recovery-if available), clinical features, and investigation reports, was transferred to an electronic data collection sheet (Microsoft Excel). After completion of all data collection, analysis was conducted through a spreadsheet. Comparison between two disease groups was made by independent t-test. Within the group, the analysis was done by the Chi-Square test. Results: In this thesis study, it was found that the most common organism responsible for CAP was Streptococcus spp. (34.70%) and is sensitive to Meropenem (92.21%), Imipenem (88.16%), Amikacin (70.67%), Piperacillin (70.91%), Moxifloxacin (70.96%), Levofloxacin (67.95%), Amoxiclav (67.92%), and Ceftriaxone(63.95%). The most common causative organism responsible for VAP was Staphylococcus spp. (36.51%) and it was sensitive to Imipenem (100%), Moxifloxacin (100%), Meropenem (94.73%), Amikacin (85.71%), Ceftriaxone (60%), Amoxiclav (66.66%), Levofloxacin (57.14%), and Cefuroxime (50%). Conclusion: Pneumonia is still one of the most common reasons for hospitalization, particularly for those admitted to ICU. It has been observed in several studies that the majority of the cases are communityacquired pneumonia. Many mechanically ventilated patients often develop VAP, which is fatal if timely diagnosis and appropriate antibiotics administration are not made. Streptococcus spp. was the most common organism responsible for CAP, and Staphylococcus spp. mainly was responsible for VAP.

Introduction: Pneumonia is a worldwide, serious threat to health and an enormous socio-economic burden for health care system. According to recent WHO data, each year 3-4 million patients die from pneumonia. The clinical presentations and bacterial agents responsible for community acquired pneumonia (CAP) varies according to geography and culture.Methods: A cross sectional observational study conducted among the 53 consecutive patients with a clinical diagnosis of CAP in admitted patient in the department of Medicine, DMCH, during January 2010 to December 2010. Hematological measurements (TC of WBC, Hb%, ESR, platelet count), blood culture, chest X-ray P/A view, sputum for Gram staining and culture sensitivity, sputum for AFB, blood urea and random blood sugar were done in all cases. ELISA for IgM antibody of Mycoplasma pneumoniae and Chlamydia pneumoniae were done in sputum culture negative cases.Results: The mean (±SD) age was 38.9±17.3 years and Male female ratio was 3:1. Fever, chest pain and productive cough were the most common clinical features. The mean (±SD) respiratory rate was 23.0±2.8 /minute . COPD and DM were found in 17.0% and 5.7% of patients respectively . Blood culture was found positive in only 1.9% of the study patients. Gram positive Cocci 62.26%, Gram negative Bacilli 9.43%, mixed Gram positive cocci and Gram negative bacilli 11.32% and Gram negative Cocco Bacilli 1.9% were observed and in 15.03 % cases, no bacteria could be seen. Sputum culture revealed 53.8% streptococcus pneumoniae, 26.9% Klebsiella pneumonia as predominant organism. Mycoplasma pneumoniae and Chlamydia pneumoniae were found in 7.4% and 3.7% respectively by serological test. For Streptococcus pneumoniae, sensitive antibiotics were Amoxyclav and Levofloxacin. For Gram negative bacilli and coccobacilli, more sensitive antibiotics were Meropenem, Ceftriaxone, and Clarithromycin. The best sensitive drug were found meropenem. The mean (±SD) duration of hospital stay was 5.0±1.7 days with ranging from 3 to 10 days.Conclusion: Region based bacteroiological diagnosis of Cap is important for selecting the best and sensitive drugs for complete cure.J Bangladesh Coll Phys Surg 2016; 34(3): 128-134

Introduction: Neonatal sepsis is one of the major causes of neonatal morbidity and mortality especially in developing countries. The clinical signs and symptoms of neonatal sepsis are non specific and blood culture report is considered gold standard for confirmation of neonatal sepsis. Organisms and their sensitivity pattern vary from place to place. The confirmation of diagnosis and management of neonatal sepsis is challenging and time consuming.Objective: The aim of this study was to find incidence of blood culture proven sepsis in suspected early onset neonatal sepsis, find out sensitivity pattern of isolated organism and to find association of risk factors and clinical signs and symptoms with blood culture proven sepsis.Methodology: Prospective study was conducted in Nobel Medical College, Biratnagar from November 2016 to November 2017. Sample size was calculated to be 300 and blood culture was sent of each neonates admitted with suspected early onset neonatal sepsis before giving neonates with first dose of antibiotics and report of 72 hours was taken into consideration.Results: Out of 300 cases of suspected early onset neonatal sepsis 70.3% presented with lethargy, followed by other symptoms like poor feeding, respiratory distress, fever, hypothermia, feeding intolerance, abnormal body movement and abdominal distension. Low birth weight neonates, preterm neonates, prolonged duration of per vaginal leaking and low platelets count were significantly associated with blood culture proven sepsis in this study. Incidence of blood culture positive sepsis in suspected early onset neonatal sepsis was 27%. Coagulase negative Staphylococcus aureus(21%) was predominant organism isolated followed by Klebsiella Pneumonia, Pseudomonas, Escherichia coli. All of the isolated Klebsiella and Pseudomonas and 86% of Escherichia coli were found to be resistant to ampicillin. All isolated Coagulase negative Staphylococcus aureus were sensitive to vancomycin.Conclusion: Coagulase negative Staphyloccus aureus was predominant organism detected but majority of organisms were gram negative organisms. High resistance to ampicillin was found and cefotaxime was also less sensitive to isolated organism. Vancomycin was found to be sensitive to all isolated Staphylococcus aureus and coagulase negative Staphylococcus aureus. Amikacin was highly sensitive among causative organisms isolated. BJHS 2018;3(1)5 : 370-376

Typhoid and paratyphoid fevers, collectively known as enteric fever, is caused by Salmonella enterica subspecies serovars Typhi and Paratyphi A, B and C. Despite this declining global trend, enteric fever is still considered to be a major public health hazard in Bangladesh and other developing countries due to poor sanitation, inadequate food safety measures and poor personal hygiene. In Bangladesh, the incidence of typhoid fever was reported to be 200 episodes per 100,000 person-years during 2003–2004. Multidrug-resistant (resistance to the first-line antimicrobials ampicillin, cotrimoxazole, and chloramphenicol) strains of S. Typhi and S. Paratyphi are on the rise globally and even cases of extensively drug-resistant (XDR) typhoid cases resistant to chloramphenicol, ampicillin, trimethoprim-sulfamethoxazole, third generation cephalosporins and fluoroquinolones are being reported from many corners of the world. This descriptive, observational study was carried out in Rajshahi Medical College Hospital Hospital, Rajshahi, Bangladesh from July 2017 to June 2019. Antibiotic sensitivity pattern of total 76 cases of enteric fever due to Salmonella Typhi were studied. Blood culture was carried out by BACT ALERT-3D, Automated blood culture analyzer from BioMeriuex SA, France Patented FAN Plus method. Based on the minimum inhibitory concentration (MIC), the organism was categorized as sensitive, intermediate, and resistant against the respective antibiotics as per Clinical and Laboratory Standards Institute (CLSI) criteria. We are reporting antibiotic sensitivity and resistant patterns of S. Typhi documented in Rajshahi Medical College Hospital, a large tertiary care hospital in Northern Bangladesh.

Background: Acute Kidney Injury (AKI) is a common complication in patients admitted to the intensive care unit (ICU) and numerous causes are responsible for its development. The aim of the present study is to assess the incidence, risk factors, and outcome of patients who develop AKI in our ICU.Methodology: This study was conducted by the Department of Nephrology, Anwer Khan Modern Medical College Hospital (AKMMCH), a tertiary level center of Dhaka, during the period of January 2015 to December 2015. This is a Cross Sectional Descriptive type of Observational study on patients of Acute Kidney Injury (AKI) admitted to Intensive Care Unit (ICU) of AKMMCH.Result: A total number of 271 patients were admitted. Out of 271 patients, 59 (21.77%) patients with AKI who met our study requirements were included in the study and were evaluated. Among 59 patients 32 (54.23%) were males and 27 (45.77%) were females, with a male to female ratio of 1.19:1. The cause of admission were Diabetes mellitus with complication 11 (18.64%), Hepato-renal syndrome 10 (16.94%), Malignancy 7 (11.86%), Septicaemia 6 (10.18% ), Pneumonia 6 (10.18%), Intra-uterine death (IUD) 5 (8.48%) and others (Acute Myocardial Infarction, Non ST segment Elevated MI, Cerebro Vascular Disease, Gullain Burre Syndrome, Laparatomy, Type I and Type II Respiratory failure) 14 (23.72%). According to RIFLE's criteria most of the patients were from Injury group 32 (54.23%). Next to this, was Risk group 17 (28.83%) and in Failure, Loss and ESRD group were 7 (11.86%), 1(1.69%) and 2 (3.39%) accordingly. Regarding biochemical abnormality, mean Serum creatinine was 3.68 ± 2.15 and that of Urine output, HbA1C and HCO3 level ( in ABG ) were 4.57 ± 8.89, 6.91±1.4 and 17.14 ± 3.8 respectively. Out of 59 patients 10 (16.95%) needed Haemodialysis. According to RIFLE's criteria 7 (70%) were from Failure group, 1 patient from Loss group and 2 from ESRD group who received haemodialysis. 72.88% (43) patients improved, out of which 57.62% (34) got discharged from ICU after full recovery. 6.48% (4) patients expired and 3.38% (2) turned into ESRD and advised for regular haemodialysis.Conclusion: The incidence of AKI is high in patients admitted to ICU, and the development of AKI is associated with poor outcome and reduced survival. AKI significantly increases the duration of ICU stay, and this is likely to add to the healthcare burden. Age, gender or the presence of comorbidities do not appear to influence the incidence of AKI in our ICU patients.Anwer Khan Modern Medical College Journal Vol. 8, No. 1: Jan 2017, P 38-44
