Reporting the Undiagnosed Cases of Hepatitis B and Hepatitis C Viruses among Patients Undergoing Elective Eye Surgery in a Specialized Eye Hospital in Egypt

Gender differences in prevalence of hepatitis C virus infection in Egypt: a systematic review and meta-analysis

Egypt is the country with the highest known hepatitis C virus (HCV) prevalence worldwide. The origin of gender differences in HCV prevalence is not usually well understood. This systematic review and meta-analysis aimed to review and evaluate the gender differences in HCV infection rates amongst Egyptians. Such data would be important to support prevention and control programs aiming to minimize HCV-related morbidity and mortality. PubMed, Scopus, and Web of Science (WOS) were searched for relevant articles published from 1st January 2011 to 13th December 2021, using the search terms (HCV OR "hepatitis C" OR hepacivirus) AND (prevalence OR seroprevalence OR epidemiology OR incidence OR magnitude). At first, retrieved articles were screened, and then relevant data were extracted and analyzed. Descriptive statistics were used for data analysis. Out of 616 studies from databases, only 30 were included after the full-text screening, with 193,621 included participants: 97,597 male and 96,024 female. The overall seroprevalence of HCV antibodies in all included studies was 0.02 (CI - 0.23 to 0.28), with no significant difference between males and females. However, HCV RNA positivity was significantly more prevalent in males than females in adults and the general population (after excluding high-risk groups). In children, no statistically significant differences between males and females were found in the seroprevalence of HCV antibodies nor in the prevalence of PCR positivity. HCV RNA positivity is significantly higher in males than females in adults, while there are no gender differences in children.

Assessment of Hepatitis B, Hepatitis C and Human Immunodeficiency Virus Screening Results Performed Before Elective Eye Surgery

Objective: Although preoperative screening for Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections in patients is a controversial issue in terms of cost-effectiveness and patient privacy, this practice is commonly carried on by surgical branches. The goals of this study were to evaluate the prevalence of preoperative HBV surface antigen (HBsAg), anti-HCV and anti-HIV antibodies, as well as whether seropositive patients were referred to the infectious diseases outpatient clinic. Methods: In this study, blood samples from 884 patients who underwent elective eye surgery at Tokat Gaziosmanpasa University Medical Faculty Hospital between August 2019 and April 2021 were researched for HBsAg, anti-HCV and anti-HIV positivity and seroprevalences were determined. It was also determined whether patients with seropositivity from the hospital automation system had previously been diagnosed and if newly diagnosed patients applied to the infectious diseases outpatient clinic in the subsequent period. Results: The study comprised a total of 884 patients. Males comprised 457 (51.7%) of all patients, with a mean age of 63.21± 16.05. In 29/839 (3.3%) of the patients, HBsAg was positive. Anti-HCV positivity was found in 21/872 (2.4%) people. Anti-HIV positivity was not detected in any of the patients. Conclusion: It would be a more accurate and effective approach to increase compliance with standard hygiene and protection measures rather than requesting routine pre-operative testing for HBV, HCV and HIV. If these tests reveal seropositivity, the patient should be informed of the disease and referred to an infectious disease specialist.

Hepatitis C virus infection and risk factors among patients and health-care workers of Ain Shams University hospitals, Cairo, Egypt

BACKGROUND

Hospitals are suspected of playing a key role in HCV epidemic dynamics in Egypt. This work aimed at assessing HCV prevalence and associated risk factors in patients and health-care workers (HCWs) of Ain Shams University (ASU) hospitals in Cairo.

METHODS

We included 500 patients admitted to the internal medicine or surgery hospital from February to July, 2017, as well as 50 HCWs working in these same hospitals. Participants were screened for anti-HCV antibodies and HCV RNA. A questionnaire was administered to collect data on demographic characteristics and medical/surgical history. For HCWs, questions on occupational exposures and infection control practices were also included.

RESULTS

The overall prevalence of anti-HCV antibodies was 19.80% (95% CI: 16.54-23.52) among participating patients, and 8.00% (95% CI: 0.48-15.52) among participating HCWs. In HCWs, the only risk factors significantly associated with anti-HCV antibodies were age and profession, with higher prevalence in older HCWs and those working as cleaners or porters. In patients, in a multivariate logistic regression, age over 50 (aOR: 3.4 [1.9-5.8]), living outside Cairo (aOR: 2.1 [1.2-3.4]), admission for liver or gastro-intestinal complaints (aOR: 4.2 [1.8-9.9]), and history of receiving parenteral anti-schistosomiasis treatment (aOR: 2.7 [1.2-5.9]) were found associated with anti-HCV antibodies.

CONCLUSIONS

While HCV prevalence among patients has decreased since the last survey performed within ASU hospitals in 2008, it is still significantly higher than in the general population. These results may help better control further HCV spread within healthcare settings in Egypt by identifying at-risk patient profiles upon admission.
