Incidence of hepatitis c virus seroconversion among hemodialysis patients in the Nile Delta of Egypt: A single-center study.

Egypt has the highest worldwide prevalence of hepatitis C virus (HCV) infection, caused in part by nosocomial transmission. Patients on hemodialysis (HD) are at especially high risk of infection. We aimed to estimate the incidence of seroconversion among HCV-negative patients undergoing regular HD at a unit in a large public hospital in the Nile Delta of Egypt, which implements the Egyptian Ministry of Health guidelines for infection control, and an isolation policy for hepatitis-positive patients.

Excess mortality rate associated with hepatitis C virus infection: A community-based cohort study in rural Egypt.

Background & Aims: >80% of people chronically infected with hepatitis C virus (HCV) live in resource-limited countries, yet the excess mortality associated with HCV infection in these settings is poorly documented.

Methods: Individuals were recruited from three villages in rural Egypt in 1997-2003 and their vital status was determined in 2008-2009. Mortality rates across the cohorts were compared according to HCV status: chronic HCV infection (anti-HCV antibody positive and HCV RNA positive), cleared HCV infection (anti-HCV antibody positive and HCV RNA negative) and never infected (anti-HCV antibody negative).

Skin Prick Test Reactivity to Aeroallergens among Egyptian Patients with Isolated Allergic Conjunctival Disease.

Allergic conjunctival disease (ACD) is a type of ocular allergy, which includes seasonal allergic conjunctivitis (SAC), perennial allergic conjunctivitis (PAC), and vernal keratoconjunctivitis (VKC). Little is known about the pattern of sensitization or prevalent aeroallergens among patients with isolated ACD in Egypt We aimed to evaluate the prevalence of skin prick test positivity to common aeroallergens among Egyptian patients with isolated allergic conjunctival disease. The study included 75 patients with isolated ACD recruited from a tertiary Egyptian outpatient clinic.

Effect of preventive and curative interventions on hepatitis C virus transmission in Egypt (ANRS 1211): a modelling study.

Background: Most hepatitis C virus (HCV) transmission in Egypt is related to medical injections and procedures. To control the spread of HCV, the Egyptian Ministry of Health initiated awareness and education campaigns, strengthened infection control in health-care facilities, and subsidised anti-HCV treatment. We aimed to investigate the effect of these interventions on the spread of HCV by mathematical modelling.

A novel method to identify routes of hepatitis C virus transmission.

Background: We propose a new approach based on genetic distances among viral strains to infer about risk exposures and location of transmission at population level.

Methods: We re-analysed 133 viral sequences obtained during a cross-sectional survey of 4020 subjects living in a hepatitis C virus (HCV) endemic area in 2002. A permutation test was used to analyze the correlation between matrices of genetic distances in the NS5b region of all pairwise combinations of the 133 viral strains and exposure status (jointly exposed or not) to several potential HCV risk factors.

Prolactin and dehydroepiandrosterone sulfate: are they related to the severity of chronic urticaria?

Background And Aims: Elevated prolactin and reduced dehydroepiandrosterone sulfate (DHEA-S) levels are associated with autoimmune diseases. A limited number of studies have investigated these hormones in chronic urticaria (CU). The autologous serum skin test (ASST) reaction has also been linked to autoimmune diseases, and a positive reaction is usually associated with a more severe disease.

Women in Cairo, Egypt and their risk factors for unmet contraceptive need: a community-based study.

Background And Methodology: Although modern family planning methods are readily available in Egypt at low cost, a considerable proportion of women still have an unmet contraceptive need. The aim of this study was to detect the risk factors of unmet contraceptive need among married women in the childbearing period in an underprivileged area in Cairo with high population density. A survey of 2340 women in the Marg district of Eastern Cairo was conducted by means of home interviews.

Is the hepatitis C virus epidemic over in Egypt? Incidence and risk factors of new hepatitis C virus infections.

Objectives: To estimate hepatitis C virus (HCV) incidence rates and identify risk factors for current HCV transmission with emphasis on the role of living with infected household family members in rural Egypt.

Methods: A 4-year population-based, cohort study of seronegative villagers was conducted to identify incident HCV seroconversion cases. A risk factor questionnaire and blood samples for anti-HCV EIA-3 and HCV RNA polymerase chain reaction testing were collected at two rounds of follow-up.

Assessment of the role of interleukin-6 in diagnosis of hepatocellular carcinoma.

Interleukin-6 (IL-6) is a promising tumor marker for hepatocellular carcinoma; HCC. IL-6 may help to identify a subset of HCC patients with low alpha-fetoprotein (AFP) level, and may serve as complementary tumor marker, however, this has to be clarified. This study assesses the value of measuring serum level of interleukin-6 in patients with chronic liver disease and HCC, and evaluates its sensitivity and specificity in comparison to AFP in early diagnosis of HCC.

Evidence for a dominant major gene conferring predisposition to hepatitis C virus infection in endemic conditions.

Hepatitis C virus (HCV), infecting 170 million people worldwide, is a major public health problem. In developing countries, unsafe injections and blood transfusions are thought to be the major routes of transmission. However, our previous work in a population from Egypt, endemic for HCV, revealed highly significant familial correlations, strongly suggesting the existence of both familial transmission of the virus and genetic predisposition to HCV infection.

Prevalence of intestinal parasitosis in a rural population in Egypt, and its relation to socio-demographic characteristics.

A cross-sectional study was conducted in a village in Menoufia Governorate, Egypt where the majority of people had individual trenches in the houses for sewage disposal with absence of public sewage system. Out of 2292 stool samples 47.8% had at least a single infection.

HCV-related morbidity in a rural community of Egypt.

The origin of the hepatitis C virus (HCV) epidemic in Egypt has been attributed to intravenous schistosomiasis treatment in rural areas in the 1960s to 70s. The objective of this study was to estimate the HCV-related morbidity in a rural area where mass schistosomiasis treatment campaigns took place 20-40 years before. The study sample included 2,425 village residents aged 18-65 years recruited through home-based visits.

Changing pattern of hepatitis C virus spread in rural areas of Egypt.

Background/aims: To identify patterns of HCV spread in the Nile Delta of Egypt.

Methods: Residents in a Nile Delta village were invited to participate in a cohort study of HCV infection. Risk factors for past or current infection were identified at cohort intake using generalized estimated equations models.
