    ABSTRACT: The aim of this population-based study was to assess the incidence rates of infectious diseases in native- (Italian) and foreign-born (immigrants) populations in a North Italy area, in 2006-2010. Crude, age-specific incidence rates (IRs) and age-standardised rate ratios (SRRs) between foreign- and native-born subjects and their 95 % confidence intervals (95 % CI) were estimated. A total of 32,554 cases of infectious diseases were found (9.9 % in foreign-born subjects). The highest SRRs between foreign- and nativeborn subjects were found for tuberculosis (SRR = 27.1; 95 % CI 21.3-34.3), malaria (SRR = 21.1; 14.6-30.4), scabies (SRR = 8.5; 7.6-9.4), AIDS (SRR = 2.5; 1.8-3.4) and viral hepatitis B (SRR = 3.3; 2.1-5.2). The highest IR was found for AIDS in people from the Americas (IR = 4.57; 95 % CI 2.2-8.4), for malaria and tuberculosis in people from Africa (IR = 13.89; 11.6-16.5 and IR = 11.87; 9.8-14.3 respectively). Therefore immigrants are at a higher risk of acquiring some common infectious diseases compared to the native population in Western European countries.

    ABSTRACT: OBJECTIVES: The aim of the study was to investigate the incidence of AIDS-defining cancers (ADCs) and virus-related and non-virus-related non-AIDS-defining cancers (NADCs) in HIV-infected patients compared with the general population, and to assess the risk factors associated with these malignancies. METHODS: We performed a retrospective cohort study for the period from 1999 to 2009 of HIV-infected patients residing in the Local Health Authority of Brescia (northern Italy). Observed cancers in patients with HIV infection were compared with expected cancers in the population living in the same area using standardized incidence ratios (SIRs). Risk factors were assessed using Poisson regression analysis. RESULTS: A total of 5090 HIV-infected patients were included in the study, with 32 390 person-years of follow-up. We recorded 416 tumours in 390 HIV-infected patients. Two hundred of these (48.1%) were ADCs, 138 (33.2%) were non-virus-related NADCs and 78 (18.7%) were virus-related NADCs. An increased risk (SIR = 4.2) of cancers overall was found in HIV-infected patients. A large excess of ADCs (SIR = 31.0) and virus-related NADCs (SIR = 12.3) was observed in HIV-infected patients, while the excess risk for non-virus-related NADCs was small (SIR = 1.6). The highest SIRs were observed for Kaposi sarcoma among ADCs and for Hodgkin lymphoma among virus-related NADCs. Conversely, among non-virus-related NADCs, SIRs for a broad range of malignancies were close to unity. In multivariate analysis, increasing age and CD4 cell count < 50 cells/μL were the only factors independently associated with all cancers. CONCLUSIONS: Among HIV-infected people there was an excess of ADCs and also of NADCs, particularly those related to viral infections. Ageing and severe immunodeficiency were the strongest predictors.

    ABSTRACT: The aim of the study was to estimate the burden and direct costs of diseases in HIV-infected patients (either opportunistic illnesses or other chronic diseases) with respect to the HIV-uninfected population. These estimates will be useful for the projection of future direct costs of HIV care. A population-based study was conducted in the Brescia Local Health Agency in northern Italy. An administrative database recorded diagnoses, deaths, drug prescriptions and health resource utilization for all medical and surgical patients in the region from 2003 to 2007. The study estimated the prevalence of HIV infection as well as HIV-related mortality and annual cost per patient, and compared mortality and costs related to HIV infection with those for a set of 15 other chronic diseases. The standardized hazard ratio (SHR) and standardized mortality ratio (SMR) were obtained using an indirect standardization method. The prevalence of HIV infection increased from 218 per 100,000 inhabitants in 2003 to 263 per 100,000 in 2007. Although mortality rates decreased markedly (from 24 per 1000 HIV-infected patients in 2003 to 16 per 1000 in 2007), the data show that mortality was still higher in HIV-infected patients compared with the general population in the most recent years (SMR 8.8 in 2007). In each year included in the study, HIV-infected patients had higher rates of care-seeking for chronic diseases, including liver diseases (SHR>8), neuropathy, oesophagus-gastro-duodenum diseases, serious psychiatric disorders and renal failure (SHR approximately 3 for each). Also, the rate of medical attendance for neoplasias, chronic pulmonary disease, diabetes, and cardiovascular disease increased over time in HIV-infected patients compared with the general population. Ranking diseases in order of their total cost to the health system, HIV infection ranked 12th, with total costs of €28.6 million in 2007. Ranking in order of cost per patient, HIV infection ranked third, with a cost per patient of €9894 in 2007. HIV-infected patients with concomitant chronic diseases had higher average costs. The cost per patient in 2007 was €8104 for HIV-infected patients without other chronic diseases, €9908 for HIV infection plus cardiovascular disease, €11,370 for HIV infection plus chronic liver disease and €12,013 for HIV infection plus neoplasias. The prevalence and population cost of people living with HIV are likely to increase as a result of prolonged survival, aging of HIV-infected patients and increased risk of other chronic diseases. In the near future, HIV infection will rank as one of the most costly chronic diseases. Prevention strategies need to be more widely adopted to control the growing burden of the HIV epidemic and other chronic diseases affecting HIV-infected patients.

    ABSTRACT: Polychlorinated biphenyls (PCBs) have been hypothesized to increase the risk of non-Hodgkin lymphoma (NHL), although conclusive evidence is still lacking. High levels of PCBs were found in soil in some areas close to a PCB-producing factory in Brescia, North Italy. We conducted a population-based case-control study among residents of the town to investigate the possible association between PCB pollution and NHL in this area. We included both incident and deceased NHL cases, and a random sample of the town residents as controls, frequency matched to cases as regards age and gender. Exposure to PCBs was estimated on the basis of the lifetime residential history of cases and controls in four different areas of the town-A, B and C (polluted areas) and D (control area). A total of 495 cases (287 incident cases) and 1467 controls were enrolled. Positive associations were found between NHL and having resided for at least 10 years in the area A, the most polluted area (odds ratio, OR=1.8; p=0.02) and for having resided in any of the polluted areas considered together (A+B+C) (OR=1.4; p=0.08). However, no associations were evident for having resided 20 years or longer in the polluted areas or when analyzing the association with each subject's main residence in his/her lifetime. This study provides some evidence for an association between PCB exposure and NHL, though results should be considered with caution in the absence of individual biological measures of exposure.

    ABSTRACT: IntroductionPostinfectious irritable bowel syndrome (PI-IBS) may develop in 4–30% of patients following bacterial gastroenteritis (GE), but limited information is available on outcome of viral GE. On summer 2009 a massive community outbreak of Norovirus and Enterovirus GE occurred in San Felice (Lake Garda, Italy) due to contamination of municipal drinking water.1 In order to investigate the natural history of a community outbreak of viral gastroenteritis and to assess the incidence of functional gastrointestinal disorders and PI-IBS, we carried out a prospective population-based cohort study with control group.Methods Baseline questionnaires were administered to residents within 1 month of the outbreak. Follow-up questionnaires of the Italian version of Gastrointestinal Symptom Rating Scale (GSRS, a 15 item survey scored according to a 7-point Likert scale) were mailed to patients responding to baseline questionnaire at 3 and 6 months and to a cohort of unaffected controls, living in the same area, at 6 months after the outbreak. GSRS item were grouped into five dimensions: abdominal pain, reflux, indigestion, diarrhoea and constipation. At month 12 all patients and controls were interviewed by an health assistant in order to verify Rome III criteria of IBS. T test and χ2 or fisher's exact test were used as appropriate.ResultsBaseline questionnaires were returned by 348 patients: mean age ± SD 45 ± 22 years, 53% female. At outbreak nausea (score ≥4), vomiting and diarrhoea lasting 2–3 days or more were reported by 66%, 60% and 77% of patients, respectively. Fifty per cent reported fever and 19% referred weight loss (mean 3 kg). Follow-up surveys were returned at month 6 by 185 patients and 168 controls: mean of GSRS score for each dimension is reported in the figure. At month 12 we identified 40 patients with a new diagnosis of IBS (Rome III criteria), in comparison with 3 subjects in the control cohort (p

    ABSTRACT: Little information is available on the effect of a follow-up strategy in celiac disease patients during gluten-free diet. To assess 5 year time course of t-transglutaminase antibodies (t-TG) in celiac disease patients enrolled in a community based follow-up program. Annual t-TG testing and periodical clinic visit in 2245 patients. Proportion of patients with negative t-TG progressively increased from 83% to 93% during the 5-year follow-up: poor adherence to gluten-free diet (HR 4.764), long duration of gluten-free diet (HR 0.929) and female gender (HR 1.472) were independently associated with serological outcome. In individual patients, 69% tested t-TG "persistently negative", 1% "persistently positive" and 30% "intermittently negative or positive". By applying mathematical modelling to t-TG conversion rates observed in this latter group at beginning and end of the follow-up program, the predicted proportion of t-TG negative population increased from 90% to 95% over 5 years. Time-course of t-TG serology in the community fluctuates in 1/3 of celiac disease patients suggesting inconstant adherence to gluten-free diet and need of follow-up strategy. Periodical serological and clinical follow-up is a viable and efficacious strategy to promote adherence to gluten-free diet as inferred from time-course of t-TG serology.

    ABSTRACT: A random sample of 1,495 high school student of 9th and 13th grade in Brescia, North Italy, were interviewed about their alcohol consumption, knowledge and attitudes using an anonymous self-administered questionnaire. The percentages of students who usually consumed alcoholic beverage, were 39.7% and 30.3% in males and females, respectively, in 9th grade students and were 51.4% and 23.8% in males and females, respectively, in 13th grade students. The frequency of drunkenness during the month previous the interview was, among 9th graders: 6.9% males and 8.7% females; among 13th graders: 20.7% males and 13.3% females. The following variables were positively associated with alcohol consumption: 1) regular smoking; 2) peer alcohol drinking (best friend and partner); 3) parents' alcohol consumption. When comparing the present survey with a previously carried out in 1989, similar results were found as regards alcohol consumption; on the contrary higher prevalence of drunkenness was found in the 2008 survey, that in the 1989 one.

    ABSTRACT: In Brescia a PCB production plant polluted soil and forage of the surrounding fields and caused a significant contamination of meat and milk of the cattle fed with local forage. This in turn induced elevated blood levels of PCDDs, PCDFs and PCBs in the consumers. The contamination levels and profiles measured in the perirenal fat, in the liver and in the milk of the overall 28 contaminated bovines are reported. TEQ levels varied from 30 to 81 pg WHO(2005)-TEQ g(-1) (38-103 pg WHO(1997)-TEQ) for perirenal fat, from 107 to 138 pg WHO(2005)-TEQ g(-1) fat (128-168 pg WHO(1997)-TEQ) for liver and from 45 to 50 pg WHO(2005)-TEQg(-1) fat (56-65pg WHO(1997)-TEQ) for milk; all these values are roughly tenfold higher than the European limits. Non-ortho dioxin-like (dl)PCBs are by far the largest contributors to TEQ and PCDF contribution also largely prevail over PCDD's; both these features are also present in both the contaminated forages and in the serum of consumers of contaminated food. The indicator PCB levels are in the following ranges: 226-664 ng g(-1) for perirenal fat; 929-1822 ng g(-1) fat for liver; 183-477 ng g(-1) fat for milk; their level is about 100 times higher than the regional background. The liver samples displayed an overall TEQ several times higher than the perirenal fat from either the same animal or the same pool of animals; the increase in liver concentration was significantly higher for PCDD and PCDF congeners than for dlPCBs, and it was maximum for OCCD.

    ABSTRACT: The diagnostic attitude of western physicians toward migrants' complaints is often an unstable balance between the obstinate search for exotic tropical diseases and the overappreciation of the cultural dimensions of symptoms. Such attitude may divert attention from organic diseases. The careful assessment of all levels of possible misunderstandings (prelinguistic, linguistic, metalinguistic, cultural, and metacultural) may help the physician to discriminate between illness and disease. The long and difficult itinerary leading to the correct diagnosis of congenital myopathy in a migrant from Senegal is described, together with the barriers encountered by the caring staff.

    ABSTRACT: Polychlorinated biphenyls (PCBs) may interact with several thyroid functions. Severe environmental pollution by PCBs has been observed in Brescia, Italy, due to the presence of a factory that produced these compounds until 1984. We aimed to investigate the correlation between serum levels of total PCBs and PCB 153 and thyroid hormone serum levels in adults in a cross-sectional population-based study. A total of 527 subjects were enrolled; they were face-to-face interviewed about their history of thyroid disease and provided a blood sample under fasting conditions. The serum levels of free and total triiodothyronine (FT3 and TT3), thyroxine (FT4 and TT4) and thyroid-stimulating hormone (TSH), anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin (anti-TGA), and lipid-adjusted total PCBs and PCB 153 were determined. There was no statistically significant difference in total PCB and PCB 153 concentrations in subjects with and without thyroid disease. Inverse, weak, statistically significant correlations were found between total PCBs and FT3 (Spearman's r=-0.09) and between total PCBs and PCB 153 and TSH (Spearman's r=-0.16 and -0.12, respectively). However, multiple regression analysis with FT3 and TSH serum levels as dependent variables and total PCBs and PCB 153 serum levels as predictors, including age, gender and BMI, showed a positive, rather than negative, association of PCBs and PCB 153 with FT3 and no association with TSH. This study does not support the hypothesis that relatively high PCB environmental exposure can determine substantial alterations in thyroid function among adult people.

    ABSTRACT: A chemical plant located in Brescia, an industrial city in North-Western Italy, produced polychlorobiphenyls (PCBs) during a 30-50 year period, causing widespread pollution of the surrounding agricultural area. This area contains several small farms, which principally produce veal meat for private consumption of the farmers' families. The pollution went undiscovered for many years, during which period contaminated food was regularly consumed. This paper reports the polychlorodibenzodioxin (PCDD), polychlorodibenzofuran (PCDF) and PCB levels of a serum sample pooled from the consumers of contaminated food, compared to six population groups of the city of Brescia. Four of these groups were selected in order to represent, respectively, the local general population and the residents of three zones of the polluted area, while the last two groups represented, respectively, the present and the former workers of the plant. One human milk sample from one of the consumers of contaminated food was also analyzed. Results show that the consumers of the contaminated food and the former workers of the plant display considerably higher levels than all other groups. The levels of general population and of all other groups were generally similar both to each other and to the range of literature values for unexposed populations. The respective contribution of PCDDs, PCDFs, mono-ortho and non-ortho PCBs (dioxin-like PCBs) to (Toxicity Equivalents) TEQ of the population groups of this study were also compared to literature data: the two groups with a high contamination level, together with the human milk sample, displayed a higher incidence of mono-ortho PCBs and a lower contribution of PCDD, possibly correlated with the source of contamination.

    ABSTRACT: The Local Health Autority (ASL) of Brescia has activated an innovative method of surveillance, based on the integration ofcurrent databases in a single database, Population Database (BDA), for monitoring the prevalence of chronic diseases in the area. The BDA has been set up using automatic record-linkages of databases regarding disease exemptions, drug treatments, hospital admissions and outpatient specialist visits. This enabled us to calculate the prevalence of various chronic diseases (single or grouped) and the gross average expenditure per person for each disease group. Out of the 1,092,201 people in the Brescia ASL, 275,601 had at least one chronic disease (prevalence 252.3/1,000). Diseases ofthe circulatory system were the most frequent (169.1/1,000), followed by diabetes mellitus (36 6/1,000). Having had an organ transplant was the condition with the highest per-person expenditure (Euro 16,170/year). The highest total expenditure was associated with circulatory diseases, because of the high prevalence (Euro 470,377,413). A single computerised data base is capable of achieving epidemiological aims (assessing population health status) as well as managerial and health care aims (resources management, control of the appropriateness of services, adaptation of diagnostic-therapeutic methods to international guidelines and standards).

    ABSTRACT: The identification and treatment of latent tuberculosis infection (LTBI) among immigrants are an effective strategy for TB control in developed countries. A new test for LTBI identification that uses more specific antigens of Mycobacterium tuberculosis is now commercially available under the brand name of QuantiFERON-TB Gold test. To compare QuantiFERON-TB Gold test to tuberculin skin testing (TST) for the detection of LTBI among immigrants from high endemic TB areas. Undocumented immigrants attending a district medical center were enrolled if they originated from high endemic TB areas, the time of arrival in Italy was < or = 5 years, had neither active TB disease nor known immunodeficiency status. The TST was applied according to standards and QuantiFERON-TB Gold test was performed following the manufacturer's instructions. Hundred subjects were included in the comparative analysis. TST was positive in 44% of subjects; 15% had a positive QuantiFERON-TB Gold test result. The total agreement between TST and QuantiFERON-TB Gold test was 71%, for a kappa statistics of 0.37; agreement was 100% for TST negative results, but only 34% for TST positive ones. In the multivariate logistic regression analysis, previous BCG vaccination was independently associated with a lower chance of disagreement between the tests. The prevalence of LTBI among immigrants was lower when determined by QuantiFERON-TB Gold; this may be a consequence of more specific MTB antigens used. Our results suggest that QuantiFERON-TB Gold may be used as confirmatory test for TST positive immigrants candidate to preventive therapy.
