Epidemiology of Hepatitis C Virus in the Arabian Gulf Countries: Systematic Review & Meta-Analysis of Prevalence

HIGHLIGHTS
  • HCV prevalence is at around 1% in the Arabian Gulf region.
  • Higher prevalence in expatriate populations reflects prevalence in origin countries.
  • Evidence of ongoing HCV transmission through exposures linked to medical settings.
  • Injecting drug use does not appear to be the dominant contributor to HCV incidence.
OBJECTIVE:
To systematically review and synthesize epidemiological data on hepatitis C virus (HCV) in the Arabian Gulf countries, and assess the country-specific prevalence among nationals and expatriate populations.

METHODS:
We conducted a systematic review of HCV antibody prevalence and incidence in the Arabian Gulf countries based on the items outlined in the PRISMA statement. Meta-analyses were conducted incorporating inverse variance weighting and using a random-effects model to pool summary estimates of HCV prevalence among general population groups, for nationals and the entire resident population.

RESULTS:
We identified 557 prevalence measures and one incidence measure in the Arabian Gulf countries. 
HCV prevalence among nationals was 0.24% in the United Arab Emirates (UAE), 0.44% in Kuwait, 0.51% in Qatar, and 1.65% in Saudi Arabia. No data was available for Bahrain and Oman. Among the entire resident populations, HCV prevalence was 0.30% in Bahrain, 0.41% in Oman, 1.06% in Qatar, 1.45% in Kuwait, 1.63% in Saudi Arabia, and 1.64% in UAE. Higher prevalence was observed among expatriate populations such as Egyptians. Among high risk populations, HCV prevalence was as high as 78.6% in the multi-transfused and 74.6% in people who inject drugs.

CONCLUSIONS:
National-level HCV prevalence in the Arabian Gulf region is comparable to global levels. Higher prevalence is found in specific expatriate populations reflecting the prevalence in their countries of origin. Most exposures appear to occur in high risk groups and are often linked to medical care.

Attitude of Saudi Arabian Adults Towards Consanguineous Marriage

Background: 
Research on the attitudes of Saudi adults towards consanguinity is scarce. The study aimed to explore the attitudes towards consanguinity and its associations with socio-demographic characteristics in a sample of Saudi adults.

Methods: 
A cross-sectional study was conducted using a self-administered questionnaire. A total of 386 outpatient waiting-area attendees at King Abdul-Aziz Medical City-Riyadh were included. Participants were asked about their socio-demographic characteristics, attitude towards consanguinity and the reasons behind this.

Results: 
The positive attitude towards consanguinity among the study respondents was 48.1% with 95% confidence interval (42.91–53.33%). Social and traditional culture (59.9%) were found to be the predominant reasons for favoring consanguinity in Saudi Arabia. Evidence against a positive attitude towards consanguinity was noted in respondents who received medical information about consanguinity versus those who had not received medical information (42.3% vs. 57%, p-value = 0.008). According to the multivariate logistic model, the odds of a positive attitude towards consanguinity were 2 times higher for males (adjusted odds ratio [aOR]: 2.2; 95% CI: 1.147, 4.290) and 4.1 times higher in respondents in consanguineous marriages (aOR: 4.1; 95% CI: 2.350, 7.156). The odds of a positive attitude towards consanguinity were 50% less in respondents who received health information on consanguinity compared to those who had not received health information about consanguinity (aOR: 0.50; 95% CI: 0.253, 0.863).

Conclusion: 
One in every two Saudi adults favors consanguinity however, Saudi men and women differ in their attitudes towards consanguinity. Receiving health information on consanguinity was associated with a negative attitude towards this practice.

...Consanguinity is a worldwide issue, but particularly so in the Middle East. Saudi Arabia was ranked as the second highest Arab country to have a high frequency of consanguineous marriage, with the prevalence varying in different studies from 22–55%. Exploring the attitude towards consanguineous marriages and its health-related issues among Saudis is an attempt to clarify such a problem and suggest some solutions. In this study, the positive attitude towards consanguinity among the respondents was high, with approximately half of the respondents having a positive attitude towards consanguinity...

Hepatitis C Virus and HIV Infections among People Who Inject Drugs in the Middle East and North Africa: A Neglected Public Health Burden?

People who inject drugs (PWID) are a key population at risk of hepatitis C virus (HCV) and HIV infections. Globally, 63% of PWID are HCV infected [, ] and 19% are HIV infected [], leading to an estimated 10 million and 3 million HCV- and HIV-infected PWID, respectively [–]. The Middle East and North Africa (MENA), a region comprising 23 countries from Morocco in the West to Pakistan in the East, is at the centre of major drug production and trade, creating a context of vulnerability to injecting drug use []. PWID in MENA are a large, mostly young and stigmatized population experiencing a substantial HCV and HIV burden, with potential for even further HIV epidemic growth. Yet, they lack access to comprehensive and confidential HCV and HIV testing, prevention and treatment services.

Below:  Median HCV prevalence among people who inject drugs in the Middle East and North Africa as per available studies []. Error bars represent the lower and upper bounds of the interquartile range if more than one data point was available per country.

Prevalence of Seven Sexually Transmitted Organisms by Multiplex Real-Time PCR in Fallopian Tube Specimens Collected from Saudi Women With & Without Ectopic Pregnancy

BACKGROUND:
Ectopic pregnancy (EP) is associated with maternal morbidity and occasionally mortality during the first trimester. A history of sexually transmitted infection (STI) and pelvic inflammatory disease have been implicated as major risk factors for EP. Our aim was to measure the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae, Mycoplasma genitalium (MG), Ureaplasma parvum/urealyticum, Gardnerella vaginalis, Trichomonas vaginalis and herpes simplex virus (HSV)-1&2 in Fallopian tubes collected from EP and the results were compared with those obtained from total abdominal hysterectomy (TAH) and tubal ligation.

METHODS:
This was a prospective case-control study and tubal samples were collected from 135 Saudi women recruited from 3 centres in the Western region as follow: 84 EPs, 20 TAH and 31 tubal ligations. Multiplex TaqMan PCR was performed using an IVD CE kit for the simultaneous detection of candidate pathogens following DNA extraction.

RESULTS:
Infections were detected in 31.8 % of the 135 participants either as single (11.1 %) or co-infections (20.7 %) and the frequencies were significantly higher in EP (42.85 %) compared with control (13.72 %). The rates of CT (27.4 %; P = 0.001); MG (20.2 %; P = 0.009) and HSV-1/2 (21.4 %; P = 0.01) were significantly higher in EP. No significant difference between the study groups was observed for the other pathogens (P > 0.05). Binary logistic regression also showed that infection with ≥ 2 pathogens (OR 4.9; 95 % CI: 2.2 - 11.6; P = 0.006), CT (OR 3.07; 95 % CI: 1.3 - 12.3; P = 0.002), MG (OR 2.3; 95 % CI: 1.1 - 8.6; P = 0.03) and HSV-1/2 (OR 1.7; 95 % CI: 0.75 - 5.7; P = 0.004) were associated with a significantly higher risk of developing EP.

CONCLUSIONS:
STIs are frequent in the upper genital tract of Saudi women during the reproductive age and, CT, MG and HSV-1/2 were more prevalent in EP. The observed high rates of co-infection advocate the necessity of establishing national guidelines and/or screening program utilising multiplex PCR approach for the detection of common STIs among high risk groups in the kingdom. Further studies are needed to measure the adverse reproductive outcomes associated with STIs in Saudi Arabia.

Violence Against Wives: A Silent Suffering in Northern Saudi Community

Violence against women is a worldwide epidemic. It may take different forms depending on history, culture, background, and experiences, but it causes great suffering for women, their families, and the communities in which they live. Despite its high prevalence, no previous studies that have been conducted in Arar, northern area of Kingdom of Saudi Arabia (KSA), addressing this issue could be traced.

The aim of this study was to measure the prevalence and determinants of violence experienced by ever-married women attending primary health centers in Arar city, Northern Border, KSA.

This study is a cross-sectional study conducted during the period from January to June 2014 in Arar city in the Northern Province of the KSA. Data were collected through an interviewer-administered questionnaire. A total of 208 wives (184 currently married, 16 divorced, and eight widowed) attending five randomly selected primary healthcare centers in Arar, KSA, were interviewed. Collected data provided information on both physical and emotional violence.

The study revealed that the overall prevalence of domestic violence in the studied group was 80.7 and 100.0% for physical and psychological violence, respectively. On studying the reasons for physical violence, half (50%) of the participants reported no clear cause, 19.2% reported failure to adequately care for children (such as cleaning, feeding, and dressing), and 7.8% reported causes related to poor scholastic achievement and couple conflict about appropriate approaches of upbringing of children. Suspicion on wife's fidelity was the most common form of psychological violence (21%). The perpetrator was the husband in 76.9% of cases and the husband's family was the perpetrator in 3.8% of cases. Physical violence was significantly higher during the first 10 years of marriage compared with other durations. University-educated husbands showed significantly lower percentage of physical violence against women compared with those of other educational levels.

Violence against women was highly prevalent in Arar city. Inadequate care of children and poor scholastic achievement were the most common reasons of physical violence, whereas financial conflicts and suspicion of wife's fidelity were the most common reasons for psychological violence. We recommend awareness programs aiming at educating current and future couples, and proper training of healthcare providers for assisting cases experiencing violence against women.

Human Immunodeficiency Virus & Viral Hepatitis among High-Risk Groups: Understanding the Knowledge Gap in the Middle East & North Africa Region

To identify gaps in the existing knowledge on single, dual and triple infections of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) in the Middle East and North Africa (MENA) region among men who have sex with men (MSMs), female sex workers (FSWs), injecting drug users (IDUs) and prisoners.

We performed an extensive literature search on articles published on the topic in the 25 countries of the MENA region. PubMed database was used as the main search engine. Case reports, case series, qualitative studies, editorials, commentaries, authors’ replies and animal studies were excluded. Original articles and reviews dealing with the prevalence of HIV, HBV and HCV and their co-infection were included. Data on population type, sample size, age and markers of infections were extracted from the relevant studies.

HIV, HBV and HCV are blood-borne viruses with similar modes of transmission. The categories of people at high risk of acquiring HIV-1, HBV and HCV commonly include: MSMs, FSW and IDUs. It is well established that HIV-positive individuals co-infected with HBV or HCV suffer from liver pathology associated with morbidity and mortality. Moreover, HIV-infected individuals do not respond well to treatment for HBV or HCV and hence are at increased risk of hepatic toxicity. Consequently, co-infection of HIV-positive individuals with HBV and/or HCV is a global health problem of significant magnitude. Our review reveals the paucity of epidemiological data for key populations in many countries of the region. Limited number of studies exists in the MENA region on the status of HIV, HBV and HCV and their co-infections among prisoners, MSMs and FSWs. Evidence support the continued increase of the HIV epidemic among MSMs. In addition to the lack of studies on MSMs and FSWs in the MENA region, our review highlights the lack of data on the practices, characteristics, or the status of HIV infection and viral hepatitis among male sex workers selling or exchanging sex for money.

The MENA countries are in urgent need of advanced research and strengthening of the data collection systems and reporting practices of these infections among key populations.
