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: We report an outbreak of viral gastroenteritis linked to municipal drinking water in a town in northern Italy in June 2009. Over one month we identified 299 probable cases of whom 30 were confirmed for at least one of the following viruses: norovirus, rotavirus, enterovirus or astrovirus. Water samples and filters from the water system also tested positive for norovirus and enterovirus. Control measures included treating the water system with chlorine dioxide and filters with peracetic acid, while providing temporary alternative sources of drinking water to the population.

ABSTRACT: The objective of our study was to evaluate the sociodemographic factors associated with completion of screening for latent tuberculosis infection (LTBI) among undocumented immigrants in Brescia, Italy. Screening for LTBI was offered to 649 immigrants; 213 (33%) immigrants completed the first step of screening; only 44% (55/124) of individuals with a positive tuberculin skin test result started treatment for LTBI. The univariate analysis showed that being unmarried, of Senegalese nationality and being interviewed by a health-care worker with the same native language as the immigrant were significantly associated with completion of screening for LTBI. In the multiple logistic regression, being interviewed in the native language of the health-care worker (OR 2.5, 95% CI 1.3-4.8, P = 0.004) and being of Senegalese origin (OR 2.3, 95% CI 1.4-3.6, P = 0.0005) were independently associated with adherence to LTBI screening. Our results suggest that knowledge of the sociodemographic characteristics of immigrants, and the participation of health-care workers of the same cultural origin as the immigrant during the visits, can be an important tool to improve completion of screening for LTBI.

ABSTRACT: Water samples were collected at three therapeutic thermal spas in the area of Brescia, between February and October 2000: 34.8% of the samples contained Legionella pneumophila; the predominant isolates (30%) belonged to Legionella pneumophila serogroup 1. The microorganism was present in the spa water at high concentrations, generally higher than 10000 cfu/l. The large number of positive Legionella pneumophila samples indicates a potential risk of infection to patients, especially those undergoing inhalation treatment with thermal water, or those using a whirlpool or taking a shower even if, during the study, no clinical cases of Legionnaires' disease were observed. In some inhalators in use we detected Legionella pneumophila: after a treatment to eradicate the microorganism, no sanitary fittings currently show contamination. Thus, in our opinion, they are not sources of infection when they are mantained and serviced properly. Thermal disinfection and service checks at regular intervals are suggested for contaminated systems.

ABSTRACT: Practical or cost-effective strategies to identify undocumented immigrants with latent tuberculosis infection and to deliver treatment for latent TB infection are still unavailable.
To compare completion rates of screening procedures for TB infection and disease among undocumented immigrants at specialised (TB) and unspecialised health services in Italy.
A TB unit (TBU) and an unspecialised health service unit for migrants (MHCU) served as recruitment sites for recent undocumented immigrants from TB endemic areas. The screening included a symptom questionnaire, a tuberculin skin test and a chest X-ray.
Of 1318 eligible subjects, 1232 (93.4%) accepted the screening. Screening was completed by 993 (80.6%) individuals overall, 86.5% and 71.4% at the TBU and MHCU services, respectively. In a multivariate analysis model, the only variable associated with an increased probability of completing screening was being enrolled at the TBU site (OR 2.5, 95%CI 1.8-3.5; P < 0.001). Three hundred and ninety-two subjects (39.4%) had a TST test of > or = 10 mm. Eight cases of active tuberculosis were detected, with a calculated prevalence of disease of 650/100,000.
Undocumented immigrants to Italy can be screened for TB at an unspecialised health service unit, although not as efficiently as at a specialised TB unit.

ABSTRACT: In a multicenter, prospective, randomized, open-label study of isoniazid-preventive therapy (IPT) for latent tuberculosis infection, illegal immigrants from countries where tuberculosis is highly endemic were enrolled at two clinical sites in Northern Italy. Of 208 eligible subjects, 82 received supervised IPT at a dose of 900 mg twice weekly for 6 mo (Regimen A), 73 received unsupervised IPT 900 mg twice weekly for 6 mo (Regimen B), and 53 received unsupervised IPT 300 mg daily for 6 mo (Regimen C). Supervised IPT was delivered at either one tuberculosis clinic or one migrant clinic. The probability of completing a 26-wk regimen was 7, 26, and 41% in Regimens A, B, and C, respectively (p < 0.005, Log- rank test calculated using Kaplan-Meier plots). The mean time to dropout was 3. 8, 6, and 6.2 wk in Regimens A, B, and C, respectively (p = 0.003 for regimen A versus either Regimens B or C). Treatment was stopped in five subjects (2.4%) because of adverse events. The rate of completion of preventive therapy for latent tuberculosis infection among illegal immigrants was low. Supervised, clinic-based administration of IPT significantly reduced adherence. Alternative strategies to implement preventive therapy in illegal immigrants are clearly required.

ABSTRACT: The aim of this study was to compare the occurrence of L. pneumophila in hot water samples from hot water tanks and instantaneous devices. Tanks and devices were all operated by heat exchangers employed in the town's district heating system. Thirty-six out of 171 (21%) hot water samples tested positive for L. pneumophila isolation, with 14.6% belonging to serogroup 1 and 6.4% to serogroups 2-14. The proportion of L. pneumophila detected in hot water reservoirs (30%) was higher than that observed in hot water instantaneous devices (6.2%). Differences in L. pneumophila isolation reflected different temperatures registered at the faucet: </=50 degrees C for hot water from reservoir devices, and >60 degrees C for hot water from instantaneous devices. These data emphasize the need to control temperature in hot water distribution devices, thus inhibiting the formation of biofilm and L. pneumophila colonization.

ABSTRACT: Cancer Registries are an essential part of any rational programme of cancer control, for assessing the impact of cancer in the community, for health care planning and monitoring screening programmes, according to local enviromental problems. The Brescia Cancer Registry started in 1994 producing prevalence, incidence and mortality data using only manual procedures of colletting and processing data from clinical and pathological sources in Brescia in 1993--1995. Data quality indicators such as the percentages of istologically or cytologically verified cases and that of cases registered on the basis of Death Certificate Only (DCO) are similar to those from the other Northern Italian Registries. Incidence rates for all causes and for various common sites are higher in Brescia than in other areas covered by Cancer Registries in North of Italy.

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: According to available studies, migrant workers represent a vulnerable workers' category. For this reason, the Italian law on safety and health at work (art. 11, D.Lgs 81/08) points out the need for Public Administration initiatives devoted to migrant workers' health and safety at work. Local Public Health Department of Brescia for years now had a significant commitment in migrants' health. Thanks to the collaboration of occupational physicians and expert physicians on migration health, it was developed a multidimensional method to assess working risks taking into account also the fragile conditions of migrant workers, considering both personal and social characteristics and professional experience, in order to support companies in the planning of necessary actions to improve health and safety at work. The method was shared by both local industrial association and trade unions and then tested in some manufactures.
