Background/Aims: Patients with preexisting morbidities(e.g., malignancy, posttransplant, and heart failure) are recognized to be at increased risk of severe acute respiratory syndrome coronavirus‑2 (SARS‑CoV‑2) infection, as well as increased risk of mortality after infection. However, there are conflicting data on the susceptibility and prevalence of infection among people living with HIV (PLWH), with higher, lower, and equal prevalence to the general population were reported. The aim of this study was to assess the prevalence of SARS‑CoV‑2 antibodies among PLWH who are attending clinical care at the Department of Infectious Diseases of Tripoli University Hospital. Materials and Methods: A cross‑sectional study conducted during the period from October 01, 2021 to December 01, 2021 at the (Department of Infectious Diseases) outpatient clinic of Tripoli University Hospital. The OnSite Coronavirus Disease 2019 IgG/IgM Rapid Test (CTK Biotech, San Diego County, California, USA) was used to determine the presence of antibodies against the spike protein of SARS‑CoV‑2 in the collected serum samples. The test results were reported as “Negative” or “Positive” as per the manufacturer’s instructions. Results: A total of 108 PLWH were included in the study. Sixty‑nine (64%) were male, and the mean age for participants was 44 years. Specific IgG/IgM antibodies for SARS‑CoV‑2 were detected in 31 individuals, representing a seroprevalence of 28.7%. Conclusions: High seroprevalence of SARS‑CoV‑2 antibodies among nonvaccinated PLWH attending clinical care at Tripoli University Hospital. They require pritorization on vaccination and boosting

Takayasu’s arteritis (TA) is a large‑vessel vasculitis that involves the aorta and its major branches. Renal arteries are frequently involved, usually with renovascular hypertension. The prevalence of TA in Arabs is low. A study of the epidemiological and clinical features of TA in Arabs included 197 identified patients between 1995 and 2012 and none of them was Libyan. We report a 61‑year‑old Libyan woman in whom TA manifested with hypokalemia and arterial hypertension. Previous ultrasound showed renal size asymmetry raised the possibility of renal artery stenosis. The diagnosis of TA was confirmed by magnetic resonance angiography, which showed a thickened abdominal aortic wall, occlusions of the left renal artery and left common iliac artery, stenosis of the right common iliac artery, and stenosis of both subclavian arteries. TA is rarely encountered in Arabs. However, the disease must be considered in patients who present with renovascular hypertension, in a context of other autoimmune disorders. arabic 6 English 33

OBJECTIVE: The increasing prevalence of suspected cases of coronavirus disease 2019 (COVID-19) presenting to emergency departments (EDs) requires a rapid and reliable triaging tool. The diagnostic performance of chest computed tomography (CT) has yet to be validated for triaging cases in the ED. We aimed to assess the diagnostic performance of chest CT compared to GeneXpert Xpress Xpert severe acute respiratory syndrome coronavirus 2 test in rapidly diagnosing COVID-19 among patients with respiratory symptoms presenting to the ED. MATERIALS AND METHODS: This was a retrospective, single-center study at Tripoli University Hospital including cases with respiratory symptoms who underwent chest CT as well as polymerase chain reaction (PCR) testing for suspected COVID-19 between May 18 and August 18, 2020. RESULTS: A total of 1240 cases were included, among whom 570 had radiologically evident COVID-19 on chest CT (46%). Five hundred and sixty-five cases had positive PCR results (45.6%), of whom 557 had radiologically evident COVID-19 on chest CT (97.7%). The calculated accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were 98%, 98.5%, 98%, 97.7%, and 98.8%, respectively, in relation to the PCR results. CONCLUSION: During the current pandemic, chest CT is a quick and reliable diagnostic tool for COVID-19 in the ED.
