Detection of SARS-CoV-2 RNA by Reverse Transcription-Polymerase Chain Reaction (RT-PCR) on Self-Collected Nasal Swab Compared With Professionally Collected Nasopharyngeal Swab.

BACKGROUND: Self-collection of nasal swabs for the detection of SARS-CoV-2 RNA by reverse transcription-polymerase chain reaction (RT-PCR) would considerably increase the testing capability and decrease the risk of transmission among healthcare workers (HCW) and the use of personal protective equipment (PPE). OBJECTIVES: This study aimed to evaluate the performance of self-collected nasal swabs compared with professionally collected nasopharyngeal (NP) swabs for detection of SARS-CoV-2 RNA by RT-PCR. MATERIALS AND METHODS: We performed a cross-sectional study where the suspected cases of coronavirus disease 2019 (COVID-19) were instructed about the self-collection of nasal swabs from their mid-turbinate. The results were compared to a nasopharyngeal swab collected by a trained healthcare worker in the same patient at the same sitting. RESULTS: We enrolled 100 participants, of which, 69 (69%) were male and 31 (31%) were female. The median age of the study participant was 36 years. Of the participants, 58 (58%) were symptomatic, and the commonest clinical presentation was cough, which was present in 42 (42%) participants. Out of 100 samples, 31 (31%) professionally collected nasopharyngeal swabs and 28 (28%) self-collected nasal swabs were positive for SARS-CoV-2 by RT-PCR. Out of 31 professionally collected positive samples, three samples were negative in self-collection. Out of 28 self-collected positive samples, no sample was negative in the professional collection. The sensitivity and specificity of self-collected nasal swabs compared to professionally collected nasopharyngeal swabs were 90.32% and 100.00%, respectively. The sensitivity of self-collected nasal was 100% when the cycle threshold (Ct) value of the professionally collected NP swab was less than 30. CONCLUSION: Our study showed that self-collected nasal swabs' sensitivities were similar to professionally collected NP swabs with a high viral load (low Ct value). Hence, this method could be used when the patient is symptomatic and come to the health providers in the early stage of COVID-19 illness.

Therapy Targeting Stem Cell in Patients with Decompensated Cirrhosis of Liver in a Tertiary Treatment Care Center of Bangladesh.

INTRODUCTION: Decompensated cirrhosis is associated with significantly high mortality resulting from hepatic failure, and liver transplantation seems to be the only viable indication for its management. The objective of this study is to assess if granulocyte colony-stimulating factor (G-CSF), a stimulatory of stem cell in vivo, may be of any benefit for patients with decompensated cirrhosis of liver. MATERIALS AND METHODS: Seventeen consecutive patients with decompensated cirrhosis of liver were recruited in this prospective study. They received injection of G-CSF (30 IU) over a period of 6 weeks (12 injections) in addition to standard of care. RESULTS: Patients were followed up at the end of treatment and at 12 weeks of treatment. Treatment was well tolerated, and no significant adverse event was recorded in any patient. Fifteen out of 17 (88%) patients were alive at last follow-up. Although serum bilirubin, albumin, and prothrombin time improved in some patients, statistically significant improvement of Child-Pugh score could not be documented. CONCLUSION: The study establishes the safety of G-CSF therapy in patients with decompensated cirrhosis of liver. Besides, such therapy may also have survival benefit, although long-term follow-up is needed to assess its real utility in clinical perspectives.How to cite this article: Al Mahtab M, Alam SMN, Moben AL, Raihan R, Alam MA, Rahim MA, Uddin MH, Akbar SMF.

A Case of Antimitochondrial Antibody Negative Primary Biliary Cirrhosis from Bangladesh and Review of Literature.

Primary biliary cirrhosis (PBC) is very closely associated with the presence of antimitochondrial antibodies (AMA). Nevertheless, 5 to 10% of patients with typical features of primary biliary cirrhosis do not have detectable AMA. They are referred to as AMA negative PBC. We report a case of PBC who was AMA-negative. The patient was a middle-aged woman seeking help of dermatologist for her complaint of itching. The diagnosis was confirmed by histopathology, whereas other possible causes of cirrhosis were excluded.

Designing immune therapy for chronic hepatitis B.

Presently-available antiviral drugs may not be a satisfactory option for treatment of patients with chronic hepatitis B (CHB). In spite of presence of several antiviral drugs, sustained off-treatment clinical responses are not common in CHB patients treated with antiviral drugs. In addition, antiviral drug treatment may have limited effects on blocking the progression of HBV-related complications. However, substantial long-term risk of viral resistance and drug toxicity are related with maintenance antiviral therapy in CHB patients with presently-available antiviral agents. The infinite treatments with antiviral drugs for CHB patients are also costly and may be unbearable by most patients of developing and resource-constrained countries. In this situation, there is pressing need to develop new and innovative therapeutic approaches for patients with chronic hepatitis B virus (HBV) infection. Immune therapy has emerged as an alternate therapeutic approach for CHB patients because studies have shown that host immunity is either impaired or derailed or distorted or diminished in CHB patients compared to patients with acute resolved hepatitis B who contain the HBV replication and control liver damages. Both non antigen-specific immune modulators and HBV antigen-specific agents have been used in CHB patients during last three decades. However, similar to antiviral therapy, the ongoing regimens of immune therapeutic approaches have also been unable to show real promises for treating CHB patients. The concept of immune therapy for treating CHB patients seems to be rationale and scientific, however, concerns remain about suitable designs of immune therapy for CHB patients.

Epidemiology of Hepatitis E Virus in an Urban Community in Dhaka City.

INTRODUCTION: Hepatitis E virus (HEV) is endemic in Bangladesh and sporadic and epidemic outbreaks of acute hepatitis E occur in this country almost regularly. Although the real magnitude of HEV prevalence has not been documented in Bangladesh, HEV infections and HEV-related acute hepatitis of Bangladeshi origin have been reported from different parts of the world. METHODS: The study was conducted in Mirpur area of Dhaka city, which is a major residential area of the capital of Bangladesh. Three hundred adults were randomly included in the study. None had any history of jaundice or complains of liver diseases. RESULTS: The study revealed 30% prevalence of HEV in this population. The prevalence increased with age, but there was no gender difference. CONCLUSION: HEV is a highly prevalent disease in Bangladesh as elsewhere in the developing world. Since there is no specific treatment for HEV, improvement of personal hygiene and ensuring supply of safe food and drinking water remain most important approach to sustain the virus.How to cite this article: Rahman S, Mahtab MA, Jahan M, Tabassum S, Akbar SMF.

Three cases of acute or fulminant hepatitis E caused by ingestion of pork meat and entrails in Hokkaido, Japan: Zoonotic food-borne transmission of hepatitis E virus and public health concerns.

AIM: In developed countries including Japan, the transmission route of indigenous hepatitis E virus (HEV) infection is obscure. Accordingly, public health implications of indigenous HEV infection have not been well addressed. The aim of this study was to clarify the route of transmission of a small outbreak of acute hepatitis E and assess the public health implications of indigenous zoonotic HEV transmission. METHODS: Three patients with non-A, B and C acute hepatitis, two of whom presented in a critical condition, were assessed for HEV infection using polymerase chain reaction and their route of infection; the genome sequences of the infecting HEV were also analyzed. A phylogenetic tree based on the full, or near full, HEV RNA sequences were constructed by neighbor-joining method. RESULTS: All three patients ingested grilled pork meat and entrails at the same barbecue restaurant in Abashiri, Hokkaido, Japan. When comparing partial to entire, or nearly entire, nucleotide sequences of HEV detected in these patients, they were 99.9-100% identical to each other. These genotype 4 isolates had great resemblance to the genome sequences of the isolates from the mini-outbreak in 2004 in Kitami, a city adjacent to Abashiri. These Kitami/Abashiri strains were segregated into a single cluster on the phylogenetic tree of HEV genotype 4 indigenous to Japan. CONCLUSION: Indigenous HEV transmission via a zoonotic food-borne route has been demonstrated in Kitami and Abashiri via pork meat and entrails contaminated with virulent HEV strains. Because a similar outbreak can recur in the future, infection sources and distribution routes should be clarified rapidly for public health.
