Proportion of AIDS cases whose HIV infection was previously unknown at the moment of diagnosis (1996-2009)

Diagnosis of HIV is later in immigrants

Potential causes of late diagnosis:

• Infection acquired in the native

country(Akinsete OO et al, AIDS Patient Care STDs, 2007)

• Culture and language(Sobrino-vegas P et al. Current

HIV Research, 2009)

• No targeted information campaign

• Low perception of risk and of the

importance of diagnosis

• Other priorities (job, home, permesso di

soggiorno...)

• Stigmatization

• Institutional barriers

• Political and legal issues

Trends in HIV-1 subtype in new HIV-1 diagnosis in Brescia, Italy and prevalence of HIV-2 in immigrants

Prevalence of HIV-2 in HIV infected immigrants in Brescia : 01/ 2006- 01/ 2007 :

N of immigrants observed during the study period: 220/2941 = 7.5%

N of immigrants screened for HIV-2 = 141

Prevalence of HIV-2= 14/141 = 9.9%

Implication of high prevalence of non B HIV-1 subtype and HIV-2 in immigrants

•Need for HIV subtyping:●Correct meausurement of HIV RNA [1,2];● Identification of more aggressive subtypes ( ie subtype D)

need for closer monitoring off and on therapy] [3-4];●HIV-2: NNRTI uneffective fosamprenavir, enfuvirtide null or

partial efficacy [2, 5-7];●Correct interpretation of resistance testing [8-9].

Ethnicity and hepatitis: association with co-factors of liver disease progression and treatment efficacy or toxicity

Association Pathogenesis Interactions with Hepatitis viruses coinfection

African ethnicity– Renal Disease

Genetic susceptibility(HIVAN, hOAT1 …), predisposing conditions (diabetes and hypertension)

Higher rates of TDF renal toxicity

African ethnicity - metabolic syndrome

Greater BMI, lower lipid alteration and lipodystrophy , higher insulin resistance and hypertension

More rapid evolution of liver diseases ( HCV > HBV) lower IFN responsiveness

Asian ethnicity - diabetes More rapid evolution of HCV

African ethnicity and bone Higher BMD with lower bone reabsorption; lower vitamin D

Controversial effect on Tenofovir bone toxicity

African ethnicity – IFN responsiveness

Lower responsiveness to IFN and higher prevalence of IL28b SNP <> C/C

Lower efficacy of anti HCV therapy

Asian ethnicity - IFN responsiveness

Higher prevalence of IL28b SNP C/C

Higher efficacy of anti HCV therapy26
