Role of Serum Amyloid A as a Biomarker for Predicting the Severity and Prognosis of COVID-19.

Objective: To detect biomarkers that can be used to predict COVID-19 severity to identify patients with high probability of disease progression and poor prognosis.

Methods: Of the 102 patients with confirmed COVID-19 who were admitted to King Fahd General Hospital, Jeddah City, Saudi Arabia, from July 1, 2021 to August 5, 2021, 50 were included in this cross-sectional study to investigate the influence of serum amyloid A (SAA) on disease severity and survival outcomes of COVID-19 patients. Dynamic shifts in SAA, C-reactive protein (CRP), white blood cell (WBC), lymphocytes, neutrophils, biochemical markers, and disease progression were examined.

The Interplay between Zinc, Vitamin D and, IL-17 in Patients with Chronic Hepatitis C Liver Disease.

Objectives: To assess zinc (Zn) and vitamin D (Vit. D) status in chronic Hepatitis C virus- (HCV) infected patients and their relationship to interleukin- (IL-) 17 and disease severity and then investigate whether Zn and Vit. D3 modulate IL-17 expression in chronic HCV patients.

Sexual Transmission of HCV in Heterologous Monogamous Spouses.

We screened for evidence of HCV infection in healthy heterologous monogamous spouses of chronic HCV patients and studied the relation with various risk factors. A cross-sectional study of fifty healthy monogamous heterosexual spouses of HCV-positive index cases was carried out. All participants were HBV and HIV negative.

Serum dickkopf-1 level in postmenopausal females: correlation with bone mineral density and serum biochemical markers.

Objective. To assess serum level of Dickkopf-1 in postmenopausal females and its correlation with bone mineral density and serum biochemical markers. Methods.

TH1 cytokine response to HCV peptides in Egyptian health care workers: a pilot study.

Our objective was to elucidate the effects of different HCV peptides on TH1 cytokine synthesis (interleukin 2(IL2), gamma interferon (INFγ) and tumor necrosis factor α (TNF α)), in a proliferative response in a high risk population of HCV seronegative aviremic Egyptian healthcare workers (HCW). We studied the TH1 cytokine response to different HCV peptides among 47 HCW with and without evidence of HCV infection. Participants were classified according to the proliferation index (PI) in a CFSE proliferation assay as an indicator of previous exposure to HCV.

Fibroblast growth factor 23 contributes to diminished bone mineral density in childhood inflammatory bowel disease.

Background: Diminished bone mineral density (BMD) is of significant concern in pediatric inflammatory bowel disease (IBD). Exact etiology is debatable. The recognition of fibroblast growth factor 23 (FGF23), a phosphaturic hormone related to tumor necrosis factor alpha (TNF-α) makes it plausible to hypothesize its possible relation to this pathology.

HLA-DRB1 as a risk factor in children with autoimmune hepatitis and its relation to hepatitis A infection.

Background: The human leukocyte antigens (HLAs) are proteins found in the membranes of nearly all nucleated cells. People with certain HLA antigens are more likely to develop certain autoimmune diseases. The aim of this study was to determine the frequency of HLA-DRB1 in children with autoimmune hepatitis (AIH) as a risk factor for occurrence, its relation to preceding hepatitis A infection and treatment outcome.

Subclinical autoimmune thyroid disorders in Egyptian patients with untreated chronic hepatitis C virus infection.

The frequency of anti-thyroid antibodies and subclinical thyroid disorders in Egyptian patients with untreated chronic hepatitis type C was estimated. In addition, it determines the correlation between the seropositivity of anti-thyroid antibodies and serum thyroid stimulating hormone level in chronic HCV positive patients. Also, the impact of hepatic decompensation in inducing thyroid autoimmunity in such patients was evaluated.
