| 1 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory. | Iman I Salama Samia M Sami Zeinab Nabil Ahmed Said Manal H El-Sayed Lobna A El Etreby Thanaa M Rabah Dalia M Elmosalami Amany T Abdel Hamid Somaia I Salama Aida M Abdel Mohsen Hanaa M Emam Safaa M Elserougy Amal I Hassanain Naglaa F Abd Alhalim Fatma A Shaaban Samia A Hemeda Nihad A Ibrahim Ammal M Metwally | 2015 | World Journal of Hepatology2015，7，22： | 2 |

| 8 | Impact of the socioeconomic status on the severity and outcome of community-acquired pneumonia among Egyptian children: a cohort study显示文摘Background:Community-acquired pneumonia(CAP)is one of the five leading causes of death among children in developing countries,accounting for approximately three million deaths per year.Identification of the modifiable risk factors of CAP may help to reduce the burden of this disease.In this study,the impact of the socioeconomic status(SES)on the severity and outcome of CAP among Egyptian children was studied.Methods:This was a prospective longitudinal cohort study which included 1,470 children diagnosed with CAP,aged two to 15 years(median age 5.4 years).The diagnosis of CAP was based on clinical and radiological findings.A structured questionnaire and the patients’medical records were used for the data collection.The subjects were divided into two groups:mild and severe CAP.Social and demographic variables were compared,and a multivariate logistic regression analysis was performed.Results:The multivariate analysis showed that a low maternal education level(OR:3.8;95%CI:2.12-6.70;P=.0001),unavailability of adequate medical care(OR:3.1;95%CI:1.99-4.88;P=.0001),a low family income(OR:2.2;95%CI:0.99-4.78;P=.047),and parents’smoking habits(OR:2.0;95%CI:1.15-3.55;P=.014)were significant independent predictive risk factors for severe CAP among Egyptian children.Conclusion:Public health measures against these socio-demographic risk factors should be identified as priorities in order to help reduce the disease burden of deaths from severe CAP among Egyptian children. | Seham Fathy Abdel Hameed Azab Laila M Sherief Safaa H Saleh Wafaa F Elsaeed Mona A Elshafie Sanaa M Abdelsalam | 2014 | Infectious Diseases of Poverty2014，3，1： | 1 |
