Hepatitis A, B, and C infection in a community of sub-Saharan immigrants living in Verona (Italy).

Background: In Italy, about 5% of the population is represented by immigrants. The epidemiology of hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection in Africa is very different from Europe; the present study aimed to assess the seroprevalence of viral hepatitis infections in sub-Saharan African immigrants living in Verona.

Methods: A total of 182 illegal immigrants were interviewed concerning sociodemographic characteristics and epidemiological information.

HPLC analysis of HbA1c in dried blood spot samples (DBS): a reliable future for diabetes monitoring.

To simplify collection and transport of blood for HbA1c measuring, we have studied the use of a special paper that absorbs a defined volume of capillary blood and quickly dries it (dried blood-spot, DBS). The DBS can be sent to a central laboratory using regular postal service and without temperature control. This system differs greatly from other proposed DBS methods for HbA1c because it overcomes the haemoglobin alterations during the drying and storing processes, that otherwise make this analysis unreliable.
