Risk Factors and Genotypes of Hepatitis C Virus Infection in Libyan Patients

Background: The prevalence and incidence of HCV infection varies geographically due to exposure to different risk factors. Identification of HCV genotype is important to defining the epidemiology of the disease. The objective of this study was to describe genotype distribution and its relation to risk factors among HCV infected patients attending virology clinic of the Department of Infectious Diseases at the Tripoli Medical Centre. Methods: The medical records of 891 Libyan chronic HCV infected patients registered and followed up from January 2003 to January 2007 were reviewed. Data gathered includes patient\'s age, gender, risk factors and family history of HCV infection. Statistical analysis was performed using t, x2 and contingency coefficient tests. Results: The mean age was 40.22±13.09 years. Two thirds of patients were males. Normal alanine aminotransferase (ALT) at diagnosis was found in 62% of the patients. HCV RNA < 2 million copies at diagnosis was found among 54% of patients. HCV genotype 1 (G1) was the most frequent (30.9%), followed by G4 (29.2%). Genotype 2 affected 19.3% and G3 13.6%. No classification of HCV genotype was available for 2% of the patients. Many subtypes of HCV were detected with different frequencies (G1a and b, G2a, b, c and a/c, G3a and G4a and c/d). All genotypes of HCV were more common among males (

Reasons for Unwillingness of Libyans to Donate Organs after Death

Introduction: Organ transplantation in Libya depends exclusively on donations from live relatives. This limitation increases mortality and prolongs the patients’ suffering and waiting time. Objectives:The aims of this study were to explore willingness to donate organs after death and to identify the reasons for refusal. Methods: A population-based cross-sectional study was conducted from April to July 2008 on a cluster sample of 1652 persons (58% males and 42% females). The questionnaire included demographic information and mainly enquired about willingness to donate organs after death and the reasons for refusal when applicable. Results: About one-third (29.7%) of participants were in favor of donating their organs after death, 60.1% refused and 10.2% were undecided. Willingness was significantly associated with being male, younger age, having a college or graduate degree, and being single (P <0.05 for all). Lack of adequate knowledge about the importance of deceased organ donation and uncertainty about its religious implications were the most predominant reasons for refusal (43.8% and 39.5%, respectively). Other reasons included ethical concerns about retrieving organs from dead bodies (37.9%), preference for being buried intact (28%), and uneasiness about the idea of cadaver manipulation (33%). Conclusion: There were a considerable resistance to deceased organ donation, especially among females, those of older age, married people, and those with a low education level. The barriers to cadaveric donations were lack of adequate knowledge, unease about body manipulation, and concerns about religious implications. Public educational campaigns should be coordinated with religious leadership

Hepatitis B and C infection in haemodialysis patients in Libya: prevalence, incidence and risk factors

Background: Patients receiving maintenance haemodialysis (HD) are at higher risk for acquiring Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infections than the general population. Strict infection control measures are essential to prevent nosocomial transmission. We aimed to investigate the incidence and prevalence of HBV and HCV infection in the HD population of Libya as well as risk factors for infection. Methods: All adult patients receiving maintenance HD (n=2382) in Libyan dialysis centres (n=39) were studied between May 2009 and October 2010. Testing for Hepatitis B surface antigen (HBsAg) and anti-HCV antibodies was performed at initiation of dialysis and every 3–6 months thereafter. Patients who were sero-negative for HBV and HCV (n=1160) were followed up for 1 year to detect sero-conversions. Results: Participant median age was 49 years and 58% were male. 831 patients (34.9%) were sero-positive for HBV and/or HCV (anti-HCV positive 31.1%; HBsAg positive 2.6%; both positive 1.2%). Of the sero-positive patients 4.7% were known to be infected before the initiation of HD. The prevalence of HBV±HCV infection varied widely between HD centres from 0% to 75.9%. Sero-positive patients were younger, had longer time on dialysis and more previous blood transfusions. Prospective follow-up revealed an incidence of sero-conversion of 7.7% during 1 year (7.1% HCV; 0.6% HBV). Wide variation in rates of newly acquired infections was observed between dialysis centres. All new HBV cases were referred from centres already treating HBV infected patients. New HCV infections were reported in most centres but the rate of HCV sero-conversion varied widely from 1.5% to 31%. Duration of dialysis, history of previous renal transplant and history of receiving HD in another centre in Libya were significantly associated with sero-conversion. Conclusion: Patients on maintenance HD in Libya have a high incidence and prevalence of HCV infection and lower rates of HBV infection. The factors associated with HBV and HCV infection are highly suggestive of nosocomial transmission within HD units. Urgent action is required to improve infection control measures in HD centres and to reduce dependence on blood transfusions for the treatment of anaemia.
