Background: Novel corona virus (SARS-Coronavirus-2 SARS-CoV-2) which emerged in China has spread to multiple countries rapidly. Little information is known about delayed viral clearance in mild to moderate COVID-19 pa-tients. As it is highly contagious, health care workers including physicians are high risk of being infected in hospital care. Case Report: A 37 years old Bangladeshi physician working in a paediatric unit of a medical college hos-pital with multiple co-morbidities, hypertension, diagnosed axial spondy-loarthropathy (ankylosing spondylitis) taking disease modifying anti rheu-matic drugs— DMARDs (Salfasalazine) from 2016 till now, chronic persis-tent bronchial asthma on medication developed sore throat, increasing breathlessness and cough admitted to his own hospital on 22 April, 2020. He had a history of contact with a relapse nephrotic syndrome (glomerulone-phritis) patient admitted with severe respiratory distress later confirmed as COVID-19 following RT PCR test on 14 April, 2020. After 3 days of contact with the patient, the physician also developed the symptoms mentioned above. The RT PCR test result of the physician came positive on 18 April, 2020. The physician primarily taken only azithromycin 500 mg once daily along with other regular drugs. On 5, 12 and 18 May, 2020, his sample was taken for re-test and came positive subsequently. After that he started Iver-mectin (0.15 mg/kg) once daily for 3 days and doxycycline 100 mg BD for 7 days. He gave samples again on 27 and 29 May, 2020 which were came nega-tive after 39 days. On full recovery he was discharged from hospital on day 40. We choose the patient because presence of co-morbidities may be asso-ciated with delayed viral clearance and physicians with co-morbidities working in a hospital have high risk of being infected.

Background: Since 2019, the pandemic of Coronavirus disease 2019 (COVID-19) has spread very rapidly in China and Worldwide. COVID-19 is a highly contagious, infectious and rapidly spreading viral disease with an alarming case fatality rate up to 5%. Case Report: In this article, we report a case of 60 years old non diabetic, hypertensive woman infected with COVID-19 who has end stage renal disease (ESRD) on hemodialysis for last 18 months. COVID-19 patients with ESRD need isolation dialysis but most of them cannot be handled properly due to limited hemodialysis machine. With these unavailability and risk, we continue the treatment along with hemodialysis for controlling uraemia and fluid balance. With all effort this patient ended with an uneventful course with clinical improvement, improvement of all laboratory parameters and resolution of radiological findings but follow up RT-PCR cannot done due to changing guideline of discharge criteria of COVID-19 patient in Bangladesh.

A Review on D 614G Mutation with Bangladesh Scenario

Advances in Infectious Diseases 2020年第3期10卷 249-255页

作者： Arifa Akram Mohammad Jahidur Rahman Khan md. Bayzid Bin Monir md. reaz uddin chowdhury Mahmuda Yeasmin md.

With the COVID-19 pandemic, disparities between the infection rate and death rate in different countries become a major concern. In some countries, lower mortality rate compared to others can be explained by better testing capacity and intensive care facilities. Complete SARS-CoV-2 genome sequences from different countries of the world are continually submitted to Global Initiative for Sharing All Influenza Data using Next Generation Sequencing method. A SARS-CoV-2 variant with a D 614G Mutation in the spike (S) protein has become the most dominant form in the global pandemic. There are a number of ongoing studies trying to relate this mutation with the infectivity, mortality, transmissibility of the virus and its impact on vaccine development. This review aims to accumulate the major findings from some of these studies and focus its future implication. Some studies suggested D 614G strain has increased binding capacity, it affects more cells at a faster rate, so has a high transmissibility. Patients infected with this strain were found with high viral load. But still now there is no such evidence that this strain produces more severe disease as well as increased mortality. The structural change of spike protein produced by D 614G mutation was minor and did not hamper the vaccine efficacy. Some studies showed antibodies produced against D614 strain can neutralize G614 strain and vice versa. Whenever a mutation occurs in spike protein there are always chances of affecting the infectivity, transmissibility, vaccine efficacy. Therefore, more studies are required to find out the overall effect of D 614G mutation.

Background: By the dawn of this modern era of science, the prime challenge of physician is cardiovascular disease (CVD). The most important modifiable risk factors of CVDs are unhealthy diet, physical inactivity and tobacco use. The effects of unhealthy diet and physical inactivity include abnormal blood lipid, obesity and hypertension. We tried to evaluate and correlate the pattern of lipid profile in obese and non-obese hypertensive patients. Objectives: This study was conducted at medicine department of Cumilla Medical College Hospital. The principal aim was to evaluate the lipid profile in obese and non-obese adult hypertensive patients. Methodology: During this cross sectional analytical study, a total of 100 adult hypertensive patients were taken by purposive sampling. Among them 50 (group 1) patients were taken those were obese and 50 (group 2) patients taken those were non-obese according to BMI measurement on operational definition. Diagnosis of hypertension would be established with the help of ambulatory BP measurements two occasions few minutes apart. The staging of hypertension was done according to JNC7 Criteria. Morning blood samples were taken after 8 - 12 hours of fasting and lipid profiles were done on authentic laboratories. The laboratory values were interpreted according to the operational definition of dyslipidaemia. The ethical research and review committee approved the study protocol and signed informed consent was obtained from the participants. The statistics was analyzed using the IBM SPSS software of version 19.0. Statistical significance was set at p Results: Among the two groups, there were 56 (56%) males and 44 (44%) females. The mean age of group 1 (46.10 ± 11.09) was compared to that of group 2 (

Nipah virus (NiV) is a highly infectious zoonotic pathogen that poses a significant threat to human and animal health. First identified in Malaysia in 1998, NiV has since caused several outbreaks in Southeast Asia, with sporadic cases reported in Bangladesh and India. The virus is primarily transmitted to humans through direct contact with infected animals, primarily fruit bats, or through the consumption of contaminated fruits and their juices. NiV infection presents a wide spectrum of clinical features, ranging from mild respiratory illness to severe encephalitis, with a high case fatality rate. The incubation period typically ranges from 4 to 14 days, during which patients develop fever, headache, myalgia, and respiratory symptoms such as cough and sore throat. As the disease progresses, neurological signs become prominent, including altered consciousness, seizures, and focal deficits. Severe cases may exhibit acute respiratory distress syndrome and multi organ failure. Laboratory findings often include lymphocytopenia, thrombocytopenia, and elevated liver enzymes. Diagnosis of NiV infection requires specialized laboratory testing, including reverse transcription-polymerase chain reaction (RT-PCR) and serological assays. Currently, no specific antiviral treatment exists for NiV infection, and management primarily focuses on supportive care. Prevention and control strategies encompass public health interventions, surveillance, and raising awareness among healthcare providers and the general population. The emergence and re-emergence of NiV highlight the urgent need for continued research, improved diagnostic capabilities, and the development of effective vaccines and therapeutics to mitigate the impact of this deadly virus.
