Prevalence of COVID-19 vaccine reactogenicity among Bangladeshi physicians.

Increased COVID-19 vaccine hesitancy presents a major hurdle in global efforts to contain the COVID-19 pandemic. This study was designed to estimate the prevalence of adverse events after the first dose of the Covishield (AstraZeneca) vaccine among physicians in Bangladesh. A cross-sectional study was conducted using an online questionnaire for physicians (n = 916) in Bangladesh. Physicians who received at least one dose of the COVID-19 vaccine were included. The study was carried out from April 12 to May 31, 2021. More than 58% of respondents (n = 533) reported one or more adverse events. Soreness of the injected arm (71.9%), tiredness (56.1%), fever (54.4%), soreness of muscles (48.4%), headache (41.5%) and sleeping more than usual (26.8%) were the most commonly reported adverse events. Most vaccine-related reactogenicities were reported by the younger cohorts (<45 years). The majority of respondents reported severity of reactogenicity as "mild," experienced on the day of vaccination, and lasting for 1-3 days. The most common reactogenicity was pain at the injection site; the second most common was tiredness. Almost half (49.2%) of the physicians took acetaminophen (paracetamol) to minimize the effects of vaccine reactogenicity. Multivariate logistic regression analyses showed that physicians with diabetes and hypertension (OR = 2.729 95% CI: 1.282-5.089) and asthma with other comorbidities (OR = 1.885 95% CI: 1.001-3.551) had a significantly higher risk of vaccine-related reactogenicities than physicians without comorbidities. Further safety studies with larger cohorts are required to monitor vaccine safety and provide assurance to potential vaccine recipients.

Management of Children Admitted to Hospitals across Bangladesh with Suspected or Confirmed COVID-19 and the Implications for the Future: A Nationwide Cross-Sectional Study.

There is an increasing focus on researching children admitted to hospital with new variants of COVID-19, combined with concerns with hyperinflammatory syndromes and the overuse of antimicrobials. Paediatric guidelines have been produced in Bangladesh to improve their care. Consequently, the objective is to document the management of children with COVID-19 among 24 hospitals in Bangladesh. Key outcome measures included the percentage prescribed different antimicrobials, adherence to paediatric guidelines and mortality rates using purposely developed report forms. The majority of 146 admitted children were aged 5 years or under (62.3%) and were boys (58.9%). Reasons for admission included fever, respiratory distress and coughing; 86.3% were prescribed antibiotics, typically parenterally, on the WHO 'Watch' list, and empirically (98.4%). There were no differences in antibiotic use whether hospitals followed paediatric guidance or not. There was no prescribing of antimalarials and limited prescribing of antivirals (5.5% of children) and antiparasitic medicines (0.7%). The majority of children (92.5%) made a full recovery. It was encouraging to see the low hospitalisation rates and limited use of antimalarials, antivirals and antiparasitic medicines. However, the high empiric use of antibiotics, alongside limited switching to oral formulations, is a concern that can be addressed by instigating the appropriate programmes.

Nocardia infection causing non-healing surgical wounds: A case series from Bangladesh.

OBJECTIVE: Nocardia can be introduced accidentally causing non-healing surgical wounds. METHOD: From February 2017 to January 2021 samples from wounds were collected. Nocardia identification and susceptibility testing were carried out by standard procedure. RESULTS: Seventeen (35.4 %) Nocardia spp. and 20 other pathogens (41.7%) were recovered by culture. Drug susceptibility among Nocardia was >70% to amikacin, amoxicillin-clavulanic acid, levofloxacin, linezolid, and imipenem, 47% to cephalosporins and 41% to trimethoprim/sulfamethoxazole. CONCLUSIONS: Infections with Nocardia spp. should be considered in non-healing surgical wounds.

Genetic characterization of Staphylococcus aureus isolates carrying Panton-Valentine leukocidin genes in Bangladesh.

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.

Pulmonary tuberculosis and drug resistance in Dhaka central jail, the largest prison in Bangladesh.

BACKGROUND: There are limited data on TB among prison inmates in Bangladesh. The aim of the study was to determine the prevalence of pulmonary tuberculosis (TB), its drug resistance and risk factors in Dhaka Central Jail, the largest prison in Bangladesh. METHODS: Cross sectional survey with, active screening of a total number of 11,001 inmates over a period of 2 years. Sputum samples from TB suspects were taken for acid- fast bacilli (AFB) microscopy, culture and drug susceptibility testing. RESULTS: Among 1,781 TB suspects 245 (13.8%) were positive for AFB on microscopy and/or culture. The prevalence rate of sputum- positive pulmonary TB was 2,227/100,000. Fifty three cases (21.6% of 245 cases) were AFB- negative on microscopy but were found positive on culture. Resistance to isoniazid, rifampicin, streptomycin and ethambutol was 11.4%, 0.8%, 22.4% and 6.5% respectively. No multidrug resistance was observed. The main risk factors of TB in prison were exposure to TB patients (adjusted odds ratio 3.16, 95% CI 2.36-4.21), previous imprisonment (1.86, 1.38-2.50), longer duration of stay in prison (17.5 months for TB cases; 1.004, 1.001-1.006) and low body mass index which is less than 18.5 kg/m(2) (5.37, 4.02-7.16). CONCLUSIONS: The study results revealed a very high prevalence of TB in the prison population in Dhaka Central Jail. Entry examinations and active symptom screening among inmates are important to control TB transmission inside the prison. Identifying undiagnosed smear-negative TB cases remains a challenge to combat this deadly disease in this difficult setting.
