BACKGROUND The occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the sera or in the liver biopsy and the absence of hepatitis B surface antigen (HBsAg) by serological test. OBJECTIVES The current study aimed to evaluate the occult HBV infection by polymerase chain reaction (PCR) and determine HBV genotyping among the patients with abnormal alanine...
BACKGROUND Tinea pedis is a commonly encountered dermatophytic infection with a clinical prevalence of 15-25%. Limited studies have evaluated the prevalence of occult tinea pedis. OBJECTIVES The aims of this study were to evaluate the prevalence of occult tinea pedis in asymptomatic subjects with feet that appeared healthy and to identify possible related risk factors. METHODS A prospective...
Data about co-infection of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), HIV, and hepatitis C virus (HCV) are still scarce. We describe a patient hospitalized for sore throat, fatigue, myalgia with personal history HIV occult HBV infection. His antiretroviral therapy included bictegravir/emtricitabine/tenofovir alafenamide. The nasopharyngeal swab was positive SARS-CoV-2...

METHODS Between 2001 and 2010, 759 true occult bacteremia cases were identified, including 65 patients with S. aureus bacteremia. Sixty-two patien...
OBJECTIVE To determine markers of HBV infection and detect the presence of its occult infection in serum of a cohort of adult Nigerians. METHODOLOGY The study involved 28 adult Nigerians with viral hepatitis (Group 1) and 28 apparently healthy adult Nigerians as controls (Group 2). Their sera were assayed for HBsAg, HBeAg, anti-HBe, anti-HBc, anti-HBs, and anti-HCV, while HBV DNA was determin...
CONTEXT Occult HCV infection (OCI) is defined as the presence of HCV-RNA in hepatocytes and the absence of HCV in the serum according to usual tests. We aimed to define OCI and provide information about the currently available diagnostic methods. Then we focus on specific groups that are at high risk of OCI and finally investigate immune responses to OCI and the available treatment approaches. ...
