RESUMO

Burn injury is still a life-threatening event, associated with high mortality and morbidity inspite of recent advances and infection control practices. This cross sectional study was conducted at Microbiology department of Rajshahi Medical College (RMC), Bangladesh with the objective to provide an insight into the current trend of aerobic bacteria with their antibiogram in burn wound infected patients admitted in Burn and Plastic Surgery Unit of RMCH from 1st January 2016 to 31st December 2016. A total of 212 wound swabs were collected and processed as per standard protocol. The isolates were identified by standard microbiological techniques and antimicrobial susceptibility was performed by Modified Kirby-Bauer disk diffusion method. Burn injurywas highest (44.81%) in age group 21-30 years in fire related burn patients (41.98%) and female were predominant (59.91%). Among 212 samples 89.62% yielded growth and 196 bacterial species were isolated in which P. aeruginosa were the predominant organism (34.18%) followed by Proteus spp. (23.47%), Klebsiella spp. (14.80%), E. coli (11.73%), S. aureus (10.71%), Acinetobacter spp. & CoNS (2.04%) and Enterobacter spp. (1.03%). In this study meropenem, amikacin and vancomycin were highly sensitive drugs but 3rd generation cephalosporin and ciprofloxacin showed resistance. Therefore continuous microbiological surveillance and careful in vitro testing prior to antibiotic treatment is required to reduce the emergence of multidrug resistant pathogens.

RESUMO

The microbiota of the nasopharyngeal tract (NT) play a role in host immunity against respiratory infectious diseases. However, scant information is available on interactions of SARS-CoV-2 with the nasopharyngeal microbiome. This study characterizes the effects of SARS-CoV-2 infection on human nasopharyngeal microbiomes and their relevant metabolic functions. Twenty-two (n = 22) nasopharyngeal swab samples (including COVID-19 patients = 8, recovered humans = 7, and healthy people = 7) were collected, and underwent to RNAseq-based metagenomic investigation. Our RNAseq data mapped to 2281 bacterial species (including 1477, 919 and 676 in healthy, COVID-19 and recovered metagenomes, respectively) indicating a distinct microbiome dysbiosis. The COVID-19 and recovered samples included 67% and 77% opportunistic bacterial species, respectively compared to healthy controls. Notably, 79% commensal bacterial species found in healthy controls were not detected in COVID-19 and recovered people. Similar dysbiosis was also found in viral and archaeal fraction of the nasopharyngeal microbiomes. We also detected several altered metabolic pathways and functional genes in the progression and pathophysiology of COVID-19. The nasopharyngeal microbiome dysbiosis and their genomic features determined by our RNAseq analyses shed light on early interactions of SARS-CoV-2 with the nasopharyngeal resident microbiota that might be helpful for developing microbiome-based diagnostics and therapeutics for this novel pandemic disease.

RESUMO

BACKGROUND: As evidence is mounting regarding irrational and often unnecessary use of antibiotics during the COVID-19 pandemic a cross-sectional Point Prevalence Survey (PPS) (in accordance with WHO guideline) was conducted across COVID-19 dedicated wards in Dhaka Medical College and Hospital (DMCH). METHODOLOGY: Antibiotic usage data were collected from 193 patients at different COVID-19 dedicated wards at DMCH on 11 June 2020. Comparisons in antibiotic usage were made between different groups using Pearson chi-square and Fisher's exact test. RESULT: Findings reveal all surveyed patients (100%) were receiving at least one antibiotic with 133 patients (68.91%) receiving multiple antibiotics. Overall, patients presenting with the severe disease received more antibiotics. Third-generation cephalosporins (i.e. ceftriaxone) (53.8%), meropenem (40.9%), moxifloxacin (29.5%), and doxycycline (25.4%) were the four most prescribed antibiotics among surveyed patients. Diabetes mellitus (DM) was independently associated with multiple antibiotic prescribing. Abnormal C-reactive protein (CRP) and serum d-dimer were linked with higher odds of multiple antibiotic prescribing among study patients. CONCLUSION: Prevalence of multiple antibiotic prescriptions was high among severely ill patients and those with abnormal CRP and d-dimer levels. Data regarding the quality of antibiotic prescribing were lacking.

RESUMO

We report the sequencing of three severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes from Bangladesh. We have identified a unique mutation (NSP2_V480I) in one of the sequenced genomes (isolate hCoV-19/Bangladesh/BCSIR-NILMRC-006/2020) compared to the sequences available in the Global Initiative on Sharing All Influenza Data (GISAID) database. The data from this analysis will contribute to advancing our understanding of the epidemiology of SARS-CoV-2 in Bangladesh as well as worldwide at the molecular level and will identify potential new targets for interventions.

RESUMO

BACKGROUND: Adverse effects of antileishmanial drugs can affect patients' quality of life and adherence to therapy for visceral leishmaniasis (VL) and post-kala-azar dermal leishmaniasis (PKDL). In Bangladesh, there are 26 treatment centers that manage leishmaniasis cases coming from 100 endemic upazilas (subdistricts) of 26 districts (these include VL, PKDL, treatment failure, and relapse VL and cutaneous leishmaniasis cases). This study aimed to investigate the feasibility of using focused pharmacovigilance for VL (VLPV) in Bangladesh's National Kala-azar Elimination Programme for the early detection and prevention of expected and unexpected adverse drug reactions (ADRs). METHODS: This activity has been going on since December 2014. Activity area includes secondary public hospital or Upazila health complex (UHC) in hundred sub districts and Surya Kanta Kala-azar Research Center (SKKRC) in Mymensingh District, a specialized center for management of complicated VL and PKDL cases. Communicable Disease Control (CDC) of the Directorate General of Health Services (DGHS) assigned twenty five of hundred UHCs and SKKRC (total 26) as treatment centers depending on their suitable geographical location. This was implemented for better management of VL cases with Liposomal Amphotericin B (AmBisome®) to ensure patient convenience and proper utilization of this expensive donated drug. A VLPV expert committee and a UHC VLPV team were established, an operational manual and pharmacovigilance report forms were developed, training and refresher training of health personnel took place at UHCs and at the central level, collected information such as patient data including demographics, treatment history and response, adverse events were analyzed. This report includes information for the period from December 2014 to December 2016. RESULTS: From December 2014 to December 2016, 1327 leishmaniasis patients were treated and 1066 (80%) were available for VLPV. Out of these, 57, 33, 9, and 1% were new VL, PKDL, VL relapse, and other cases, respectively. Liposomal amphotericin B was mostly used (82%) for case management, followed by miltefosine (20%) and paromomycin (3%). Out of the 1066 patients, 26% experienced ADRs. The most frequent ADR was fever (17%, 176/1066), followed by vomiting (5%, 51/1066). Thirteen serious adverse events (SAEs) (eight deaths and five unexpected SAEs) were observed. The expert committee assessed that three of the deaths and all unexpected SAEs were possibly related to treatment. Out of the five unexpected SAEs, four were miltefosine-induced ophthalmic complications and the other was an AmBisome®-induced avascular necrosis of the nasal alae. The Directorate General of the Drug Administration entered the ADRs into the World Health Organization Uppsala Monitoring Centre (WHO-UMC) VigiFlow database. CONCLUSIONS: This study found that VLPV through NKEP is feasible and should be continued as a routine activity into the public health system of Bangladesh to ensure patient safety against anti-leishmanial drugs.

RESUMO

BACKGROUND: Careful monitoring for recrudescence of Wuchereria bancrofti infection is necessary in communities where mass drug administration (MDA) for the elimination of lymphatic filariasis (LF) as a public health problem has been stopped. During the post-MDA period, transmission assessment surveys (TAS) are recommended by the World Health Organization to monitor the presence of the parasite in humans. Molecular xenomonitoring (MX), a method by which parasite infection in the mosquito population is monitored, has also been proposed as a sensitive method to determine whether the parasite is still present in the human population. The aim of this study was to conduct an MX evaluation in two areas of Bangladesh, one previously endemic district that had stopped MDA (Panchagarh), and part of a non-endemic district (Gaibandha) that borders the district where transmission was most recently recorded. METHODOLOGY/PRINCIPAL FINDINGS: Mosquitoes were systematically collected from 180 trap sites per district and mosquito pools were tested for W. bancrofti using real-time PCR. A total of 23,436 intact mosquitoes, representing 31 species, were collected from the two districts, of which 10,344 (41%) were Culex quinquefasciatus, the vector of W. bancrofti in Bangladesh. All of the 594 pools of Cx. quinquefasciatus tested by real-time PCR were negative for the presence of W. bancrofti DNA. CONCLUSIONS/SIGNIFICANCE: This study suggested the absence of W. bancrofti in these districts. MX could be a sensitive tool to confirm interruption of LF transmission in areas considered at higher risk of recrudescence, particularly in countries like Bangladesh where entomological and laboratory capacity to perform MX is available.

RESUMO

BACKGROUND: Bangladesh had one of the highest burdens of lymphatic filariasis (LF) at the start of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) with an estimated 70 million people at risk of infection across 34 districts. In total 19 districts required mass drug administration (MDA) to interrupt transmission, and 15 districts were considered low endemic. Since 2001, the National LF Programme has implemented MDA, reduced prevalence, and been able to scale up the WHO standard Transmission Assessment Survey (TAS) across all endemic districts as part of its endgame surveillance strategy. This paper presents TAS results, highlighting the momentous geographical reduction in risk of LF and its contribution to the global elimination target of 2020. METHODOLOGY/PRINCIPAL FINDINGS: The TAS assessed primary school children for the presence of LF antigenaemia in each district (known as an evaluation unit-EU), using a defined critical cut-off threshold (or 'pass') that indicates interruption of transmission. Since 2011, a total of 59 TAS have been conducted in 26 EUs across the 19 endemic MDA districts (99,148 students tested from 1,801 schools), and 22 TAS in the 15 low endemic non-MDA districts (36,932 students tested from 663 schools). All endemic MDA districts passed TAS, except in Rangpur which required two further rounds of MDA. In total 112 students (male n = 59; female n = 53), predominately from the northern region of the country were found to be antigenaemia positive, indicating a recent or current infection. However, the distribution was geographically sparse, with only two small focal areas showing potential evidence of persistent transmission. CONCLUSIONS/SIGNIFICANCE: This is the largest scale up of TAS surveillance activities reported in any of the 73 LF endemic countries in the world. Bangladesh is now considered to have very low or no risk of LF infection after 15 years of programmatic activities, and is on track to meet elimination targets. However, it will be essential that the LF Programme continues to develop and maintain a comprehensive surveillance strategy that is integrated into the health infrastructure and ongoing programmes to ensure cost-effectiveness and sustainability.

RESUMO

BACKGROUND: Malaria is endemic in 13 districts of Bangladesh. A baseline malaria prevalence survey across the endemic districts of Bangladesh was conducted in 2007, when the prevalence was reported around 39.7 per 1000 population. After two rounds of Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM)-funded intervention by the National Malaria Control Programme (NMCP) and a BRAC-led NGO consortium, a follow-up survey was conducted across the malaria-endemic districts of Bangladesh to measure the change in prevalence rate and in people's knowledge of malaria. METHODS: The survey was carried out from August to November 2013 in 70 upazilas (sub-districts) of 13 malaria-endemic districts of Bangladesh, following the same multi-stage cluster sampling design and the same number of households enrolled during the baseline prevalence survey in 2007, to collect 9750 randomly selected blood samples. For on-the-spot diagnosis of malaria, a rapid diagnostic test was used. The household head or eldest person available was interviewed using a pre-coded structured questionnaire to collect data on the knowledge and awareness of malaria in the household. RESULTS: Based on a weighted calculation, the overall malaria prevalence was found to be 1.41 per 1000 population. The proportion of Plasmodium falciparum mono-infection was 77.78% while both Plasmodium vivax mono-infection and mixed infection of the two species were found to be 11.11%. Bandarban had the highest prevalence (6.67 per 1000 population). Knowledge of malaria signs, symptoms and mode of transmission were higher in the follow-up survey (97.26%) than the baseline survey. Use of bed nets for prevention of malaria was found to be high (90.15%) at respondent level. People's knowledge of selected parameters increased significantly during the follow-up survey compared to the baseline survey conducted in 2007. CONCLUSIONS: A reduced prevalence rate of malaria and increased level of knowledge were observed in the present malaria prevalence survey in Bangladesh.

RESUMO

BACKGROUND: Because access to care is limited in settings with high mortality, exclusive reliance on the current recommendation of 7-10 days of parenteral antibiotic treatment is a barrier to provision of adequate treatment of newborn infections. METHODS: We are conducting a trial to determine if simplified antibiotic regimens with fewer injections are as efficacious as the standard course of parenteral antibiotics for empiric treatment of young infants with clinical signs suggestive of severe infection in 4 urban hospitals and in a rural surveillance site in Bangladesh. The reference regimen of intramuscular procaine-benzyl penicillin and gentamicin given once daily for 7 days is being compared with (1) intramuscular gentamicin once daily and oral amoxicillin twice daily for 7 days and (2) intramuscular penicillin and gentamicin once daily for 2 days followed by oral amoxicillin twice daily for additional 5 days. All regimens are provided in the infant's home. The primary outcome is treatment failure (death or lack of clinical improvement) within 7 days of enrolment. The sample size is 750 evaluable infants enrolled per treatment group, and results will be reported at the end of 2013. DISCUSSION: The trial builds upon previous studies of community case management of clinical severe infections in young infants conducted by our research team in Bangladesh. The approach although effective was not widely accepted in part because of feasibility concerns about the large number of injections. The proposed research that includes fewer doses of parenteral antibiotics if shown efficacious will address this concern.

RESUMO

Puerperal sepsis is an important cause of maternal morbidity and mortality in developing countries. This study was undertaken to isolate and identify the anaerobic bacterial agents of puerperal sepsis among the patients admitted in Mymensingh Medical College Hospital (MMCH) during the period from July 2006 to June 2007. Endocervical swabs/secretions were collected from 50 cases of puerperal sepsis and were cultured anaerobically. Anaerobiasis was done by using gas pack (BD GAS PAK TM EZ) in anaerobic jar. Out of 50 samples, 42(84%) yielded growth in cultures. Among 42 culture positive cases, 20(40%) were Aerobic organisms and 22(44%) were mixed, i.e., Aerobic and Anaerobic bacteria. The isolated Anaerobic organisms were Peptostreptococcus 14(63.63%), Bacteroides fragilis 3(13.64%), Prevotella melaninogenica 3(13.64%) and Clostridium perfringens 2(9.09%). As a preliminary study, it was observed that anaerobic culture could be carried out with available logistic arrangement. So, it was recommended to design further study on anaerobic bacterial isolation with particular emphasis on their antimicrobial susceptibility.

RESUMO

The study was conducted to compare among the different diagnostic procedures for malaria in the department of Microbiology, Mymensingh Medical College, Mymensingh during the period from July 2005 to June 2006. In this study a total of 98 malaria patients were included as cases. Another 30 age and sex matched healthy people were included as controls. Blood sample from each of the case and control was collected and examined for malarial parasite by microscopic examination of peripheral blood film. Subsequently antigen and antibody were detected by immuno-chromatographic test (ICT). Out of 98 clinically suspected cases 59(60.20%) were positive for malarial parasite by microscopic examination of peripheral blood film, 57(58.16%) were positive by ICT for antigen and 58(59.19%) were positive by ICT for antibody. Sensitivity and specificity of ICT for antigen were 93.22% and 94.87% respectively. For antibody, sensitivity and specificity were 89.83% and 87.17% respectively. From this study, sensitivity and specificity of ICT for malaria was found quite satisfactory, so it is suggested that ICT for malaria could be an alternative to peripheral blood film for the diagnosis of malaria where parasite could not be detected in peripheral blood film.

RESUMO

A recently developed DOT enzyme immunoassay known as "Typhidot" for detecting IgM antibody against 50 KDa OMP antigen of Salmonella typhi, was evaluated on 100 clinically suspected typhoid fever cases and 40 age-sex matched controls, in the Department of Microbiology, Mymensingh Medical College during, the period from June 2006 to July 2007. Blood culture, Widal test, and DOT EIA for IgM test were performed in all patients. Among 100 clinically suspected typhoid fever cases, 35 were subsequently confirmed on the basis of positive blood culture for S. typhi and/or significant rising titre of Widal test. The DOT EIA IgM test could produce results within 1 hour. The result of the DOT EIA IgM test showed a good diagnostic value for typhoid fever. The sensitivity, specificity, positive and negative predictive value of the test was found as 91.42%, 90.00%, 88.88% and 92.30% respectively. On the other hand corresponding values for Widal test were of 42.85%, 85.00%, 71.42% and 62.96% respectively. Thus, The DOT EIA IgM seems to be a practical alternative to Widal test for early diagnosis of typhoid fever.

RESUMO

The study was under taken to detect mecA gene of methicillin resistant Staphylococcus aureus (MRSA) by PCR. It was carried out in the department of Microbiology, Mymensingh Medical College in collaboration with the Department of Medicine under the Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh between the periods from July 2006 to June 2007. A total of 40 S. aureus strains were used in this study. Isolates of S. aureus were identified by standard microbiology technique and their antimicrobial susceptibility test was done by disk diffusion method according to NCCLS. Minimum inhibitory concentration (MIC) of oxacillin was determined for all isolates by standard agar plate dilution method. All strains were tested for mecA gene by PCR. Out of 40 S. aureus strains 15(37.5%) were detected as MRSA by disk diffusion and agar dilution method but 10(25%) yielded mecA gene by PCR. Detection rate of MRSA by disk diffusion and agar dilution test showed significant difference to that by PCR (p<0.001).

RESUMO

To assess the spread and genetic characteristics of Panton-Valentine leukocidin (PVL) gene-carrying Staphylococcus aureus in Bangladesh, we investigated 59 strains (49 isolates from clinical specimens and 10 isolates colonized in the nasal cavities of medical staff), including 26 methicillin-resistant S. aureus (MRSA) strains. The PVL gene was detected only in methicillin-susceptible S. aureus (MSSA) strains (7 clinical strains and 2 colonizing strains). PVL gene-positive MSSA strains were found to belong to coagulase serotypes III or VI and were classified into sequence types ST88 (CC88), ST772, and ST573 (CC1) by multilocus sequence typing, and agr types 2 or 3. These types were different from those determined for MRSA (coagulase serotypes I and IV, ST240 and ST361, and agr type 1). PVL gene-positive MSSA possessed a larger number of virulence factor genes than MRSA, although they were susceptible to more antimicrobials. These findings suggest that the PVL gene is distributed to limited populations of S. aureus clones with specific genetic traits that are distinct from MRSA in Bangladesh, but genetically close to CA-MRSA clones in the CC1 lineage reported in the United States and European countries.

RESUMO

This prospective study was done to compare the efficacy of Tamsulosin and Finasteride for the medical treatment of symptomatic Benign Prostatic Hyperplasia (BPH) at the surgery and urology outpatient department of Mymensingh Medical College Hospital during the period from January 2003 to December 2004. Closely matched 70 patients in the age range of 50-80 years presented with lower urinary tract symptoms and clinically diagnosed as BPH were selected in the present study. Among them, 36 patients (Group I) and 34 patients (Group II) were treated with Tamsulosin (0.4 mg once daily) and Finasteride (5 mg once daily) for a duration of 06 months respectively. The efficacy of two drugs was compared on the basis of IPSS and Qmax. The base-line parameters of both groups were statistically insignificant. A significant improvement of IPSS and Qmax was found after 06 months of treatment in both groups (P<0.001). A significant improvement of IPSS Qmax was found in both groups (p<0.001) during follow-up at 1st, 2nd, 4th and 6th month. It was also observed that Tamsulosin improved the IPSS and Qmax more quickly than Finasteride.

RESUMO

A total of 345 stool specimens of hospitalized children below 5 years of age with acute gastroenteritis were tested for the presence of rotavirus by Polyacrylamide gel electrophoresis (PAGE), a monoclonal antibody based enzyme immunoassay (EIA) and a latex agglutination test (LAT). Detection rate for PAGE and EIA were 24.9% (345/86) and 20.9% (345/70) respectively. Using PAGE as the standard, the sensitivity and specificity of EIA were 75.6% and 98.1% respectively. The sensitivity of LAT was 70.9% with 100% specificity (LAT was done in only PAGE positive specimens). LAT appeared as the simplest and economic for both bed side and field use.

RESUMO

The aim of this study was to find out the pattern of extracranial complications of CSOM cases who attended to the department of ENTD, Mymensingh Medical College Hospital during the period from July'1999 to June' 2001. Different types of extracranial complications of CSOM were presented here. A total of 100 cases, diagnosed clinically and radiologically were included in the study of which 66 were male and 34 were female giving a male to female ratio of 1.94 : 1 (p < 0.05). Majority cases (53) were in the age group of 11- 20 years followed by the age group of below 10 years where there were 30 cases. Majority (64) cases came from low socio-economic class. The number of different types of extracranial complications of CSOM were as follows: mastoid abscess 57, discharging sinuses 28, purulent labyrinthitis 07, Bezold's abscess 04, fascial nerve paralysis 03 and zygomatic abscess 01. In all cases of CSOM Cholesteatoma were detected. In 14 cases, Cholesteatoma were associated with granulation tissue/polyp. Modified radical mastoidectomy were performed in all cases. On analyzing the findings of the present study it was observed that mastoid abscess were the predominant extracranial complications of CSOM, affecting mostly the male population of 11 - 20 years age group coming from low socio-economic class.

RESUMO

This prospective case-control study included 78 women between 15 to 45 years of age from rural area to see changes in serum copper level as a consequence of oral contraceptive use. Among the subjects, 34 women were included as controls because of not taking any form of hormonal contraceptives neither during the time of selection nor during one-year period prior to the study. Women in the control group were motivated to consume oral pill (Sukhi) for 3 consecutive cycles. At the 3(rd) month, 25 such women became available and henceforth included as cases on longitudinal basis. Another 44 women were randomly selected as cases on the basis of using combined oral contraceptives (Sukhi) for a duration of 4 months onwards. Considering different duration of oral contraceptive (OC) use, subjects were grouped as follows: Group I (n=34)--> controls, Group II (n=25)--> 3 months, Group III (n=17)--> 4 months - 2 years and Group IV (n=27)--> >2 years. Finally, 103 samples of blood (34 from controls and 69 from oral contraceptives users) were collected for estimation of Serum Copper (mgm/dl) by Atomic Absorption Spectrometry using UNICAM-AA Spectrometer. Mean+/-SD of Serum Copper significantly increased in all 3 contraceptive groups in comparison to controls (p<0.001). Further study including larger population from rural area was recommended to see correlation among serum copper and other trace elements with side effects of hormonal contraceptives. This preliminary study tried to explore the possibility of establishing biochemical monitoring of serum trace elements in OC users.
