Effect of obligatory Hepatitis B vaccination program on the prevalence of occult hepatitis B among pregnant women in Egypt: A cross sectional study.

Hepatitis B virus (HBV) infection is a global health problem. HBV is of intermediate endemicity in Egypt. "Occult" HBV (OBI) indicates replication of HBV-DNA in the liver of individuals with negative serum HBsAg.

Evaluation of diagnostic performance of a rapid antigen test in diagnosing COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic is our time's major global health crisis and the greatest health challenge. Reverse transcription-polymerase chain reaction (RT-PCR) test for severe acute respiratory syndrome coronavirus (SARS-CoV-2) is the gold standard technique for diagnosis of symptomatic cases and asymptomatic carriers. By 2020, antigen rapid tests have been approved for use in Covid-19 testing by regulatory bodies all over the world owing to their benefits as they are rapid and cost effective.

Pooled-Testing for SARS-CoV-2 Reverse Transcription Polymerase Chain Reaction (RT-PCR) in asymptomatic healthcare workers in EL-Raghy isolation COVID-19 hospital, Assiut University.

COVID-19 pandemic is a substantial challenge for healthcare systems. Severe acute respiratory syndrome coronavirus (SARS-CoV-2) reverse transcription-polymerase chain reaction (RT-PCR) tests are considered the gold standard technique for diagnosis of symptomatic and asymptomatic infectious viral carriers and for screening special or at-risk populations. The pooled testing procedure is commonly used to reduce the cost of screening a large number of individuals for infectious diseases.

Chlamydia trachomatis Infection: its relation to semen parameters and sperm DNA integrity.

The present study was conducted to determine the effect of Chlamydia trachomatis (CT) infection on semen quality and sperm DNA integrity. The study included 60 infertile male patients with CT infection and 25 age matched controls. Diagnosis of patients was based on detection of CT IgA by ELISA in seminal plasma and CT plasmid DNA in the semen sediment.

Toll Like Receptor 3 Polymorphisms in Hepatitis B Virus Infection.

Hepatitis B virus (HBV) is the one of the major causes of chronic liver disease. Individuals exposed to HBV show wide spectrum outcomes including immunized persons, asymptomatic carrier, chronic active hepatitis, cirrhosis and HCC. The outcome of HBV infection and the severity of associated liver diseases are determined by the nature and strength of host immune responses against the virus.

Chlamydia trachomatis: methods of identification and impact on semen quality.

Chlamydia trachomatis infection is considered to be one of the most common sexually transmitted diseases. It is currently unclear whether chlamydial infection causes pathological conditions of the male accessory glands has consequences for male infertility. To determine the frequency of C.

Alterations of the CD4(+), CD8 (+) T cell subsets, interleukins-1beta, IL-10, IL-17, tumor necrosis factor-alpha and soluble intercellular adhesion molecule-1 in rheumatoid arthritis and osteoarthritis: preliminary observations.

Rheumatoid arthritis is a multisystem disease with underlying immune mechanisms. Osteoarthritis is a debilitating, progressive disease of diarthrodial joints associated with the aging process. Although much is known about the pathogenesis of rheumatoid arthritis and osteoarthritis, our understanding of some immunologic changes remains incomplete.
