Abstract
OBJECTIVE To evaluate the changes in Bone Mineral Density (BMD) and bone remodelling markers in a group of HIV patients treated with HAART and controlled in a long follow-up and to identify possible risk factors for accelerated bone mass loss. PATIENTS AND METHODS In a series of 172 HIV patients treated with HAART a total of 67 patients (44 males and 33 females) underwent repeated bone mineral density measurement by DEXA in lumbar spine and in femur; the patients were classified according to T-score WHO criteria. Serum bone alkaline phosphatase (BAP), by IRMA, and urine pyridinoline/deoxypyridinoline (PYD&DPD), by EIA, were also assayed in all cases. RESULTS At baseline, 62/67 patients were on HAART, while 5 were naïve; 44.8% were previous intravenous drug users (IVDU), 46.3% heterosexual and 8.9% homosexual, mean age being 40.2 ± 6.5 years, and 23.9% had previous AIDS diagnosis. Fifteen/67 (22.4%) of treated patients had osteoporosis and 25/67 (37.3%) osteopenia in spine and/or femur including 3 naïve, 27/67 (40.3%), including 2 naïve, had normal BMD in both sites. Fifty-one/67 patients were monitored during follow-up (56.8 ± 5.3 months); 27 (52.9%) of these (Group 1), received protease inhibitors (PI) and 24 (47.1%), including naïve, (Group 2) received not nucleoside reverse transcriptase inhibitors (NNRTI) for > 50% of follow-up period. In Group 1 patients, BMD reduction was observed after follow-up in respect of basal condition in both spine and femur, but significantly (p = 0.011) only for the latter. However, mean BMD values remained stable in both sites in Group 2 patients. Basal BAP and PYD&DPD levels were higher in Group 1 than Group 2, but not significantly. Moreover, only PYD&DPD levels at the follow-up evaluation were significantly (p = 0.031) higher in Group 1 than Group 2. Of the remaining 16/67 patients with osteoporosis/osteopenia, 10 received PI and 6 NNRTI and were treated with therapies that could increase bone density, in particular, 9 with Alendronate/Vitamin D/Calcium and 7 with only vitamin D/calcium; these patients were excluded from statistical analysis of 51 Group 1/Group 2 cases. In the 16 patients, after these specific treatments, mean spine and femur BMD increased over time, but significantly only in those cases including alendronate in their protocol. CONCLUSIONS The study showed that in HIV patients on HAART BMD decrease, even osteoporosis, can be present persisting over time, particularly in PI in respect of NNRTI treated patients. The pathogenesis is probably multifactorial, the different antiviral drugs seeming to differently affect bone metabolism. Alendronate/Vitamin D/Calcium therapy can be useful to slow down bone mass loss and also improve osteoporosis/osteopenia conditions, thus, reducing fracture risk also continuing HAART.

Abstract
PURPOSE To evaluate the effects of alendronate, vitamin D, and calcium supplementation on bone metabolism and bone mineral density (BMD) in both HIV-infected men and women treated with highly active antiretroviral therapy (HAART). METHOD We performed a 52-week prospective, multicenter, randomized, open-label clinical trial. Eligible participants were on stable HAART and had BMD values at the femoral neck or lumbar spine that corresponded to a t score less than -1. Patients were randomized to receive alendronate 70 mg weekly or no alendronate; calcium 1000 mg daily and vitamin D 500 IU daily were provided to all study recipients. Primary endpoint of the study was the change in bone metabolism evaluated by N-telopeptide of type 1 collagen and bone-specific alkaline phosphatase; the secondary endpoint was BMD variation. RESULTS 18 patients were randomized to the alendronate and 23 to the no-alendronate group (controls). The alendronate-treatment group compared to controls had a significant decrease in serum N-telopeptides, 1914 +/- 1433.4 vs. 3967 +/- 1650.5 pM/L (p = .005) after 1 year. Lumbar spine BMD increased by 4% in the alendronate group (p = .004) vs. 3.7% (p = .062) in controls, compared to baseline values. Femoral neck BMD decreased by 0.5% in the alendronate group (p = .05) and by 3.5% in the control group (p = .04). No between-groups differences for BMD were found (Delta lumbar-BMD 0.0351 +/- 0.0406 in cases and 0.0356 +/- 0.073 in controls [p = .977], Delta femoral-BMD -0.085 +/- 0.160 in cases and -0.100 +/- 0.165 in controls [p = .795]). CONCLUSION Alendronate plus vitamin D and calcium was effective in reducing bone resorption. Alendronate improved lumbar BMD and minimized femoral BMD decrease after 52 weeks compared to treatment with vitamin D and calcium alone in patients on HAART with osteopenia/osteoporosis.

Abstract
PURPOSE To identify the presence of Human Papilloma Virus (HPV) infection and evaluate the role of Highly Active Antiretroviral Treatment (HAART) in patients with HIV-HPV co-infection. We also compared cytological screening results with HPV-DNA detection to implement screening programs and prevention of invasive cervical cancer (ICC) in HIV-infected females. PATIENTS AND METHODS We enrolled HIV-infected females presenting for routine clinical evaluation. HPV-DNA of high/intermediate and low-risk types was detected from cervical specimens by nucleic acid hybridization assay with signal-amplification. Patients were divided into two groups according to the presence of HPV co-infection (HPV+) or not (HPV-). RESULTS We enrolled 57 HIV-infected females. Median age was 40 (IQR 35-44) years, mean CD4 count was 547 ± 227 cells/mm(3), 45 (78.9%) had undetectable HIV-RNA and 52 (91.2%) received HAART. Globally, 19/57 (33.3%) patients were HPV-infected, 16/57 (28.1%) with high/intermediate and 3/57 (5.3%) with low-risk types. Five of the 19 (26.3%) HPV+ patients carried both types. Correlating high-risk genotype HPV-DNA detection with cytology, 17.5% of women with negative cytology, 36.4% with ASCUS (Atypical Squamous Cells of Uncertain Significance) and 83.4% of women with positive cytology (50% of LSIL: low-grade squamous intraepithelial lesion and 100% of HSIL: high grade SIL) were HPV positive. No statistical difference when comparing HPV+ and HPV-patients in age, CD4 cell count, in the proportion of previous intravenous-drug use, previous AIDS and of those receiving HAART with undetectable HIV-RNA was observed. CONCLUSIONS Cervical cancer screening including HPV-DNA detection should be implemented in HIV infected females across Europe, also when receiving successful HAART, to early identify the HIV patients at risk for ICC to be submitted to more frequent follow up and proper treatment.

Abstract
The etiology of multiple sclerosis (MS) is still unclear. The immuno-pathogenic phenomena leading to neurodegeneration are thought to be triggered by environmental (viral?) factors operating on predisposing genetic backgrounds. Among the proposed co-factors are the Epstein Barr virus (EBV), and the potentially neuropathogenic HERV-W/MSRV/Syncytin-1 endogenous retroviruses. The ascertained links between EBV and MS are history of late primary infection, possibly leading to infectious mononucleosis (IM), and high titers of pre-onset IgG against EBV nuclear antigens (anti-EBNA IgG). During MS, there is no evidence of MS-specific EBV expression, while a continuous expression of HERV-Ws occurs, paralleling disease behaviour. We found repeatedly extracellular HERV-W/MSRV and MSRV-specific mRNA sequences in MS patients (in blood, spinal fluid, and brain samples), and MRSV presence/load strikingly paralleled MS stages and active/remission phases. Aim of the study was to verify whether HERV-W might be activated in vivo, in hospitalized young adults with IM symptoms, that were analyzed with respect to expression of HERV-W/MSRV transcripts and proteins. Healthy controls were either EBV-negative or latently EBV-infected with/without high titers of anti-EBNA-1 IgG. The results show that activation of HERV-W/MSRV occurs in blood mononuclear cells of IM patients (2Log10 increase of MSRV-type env mRNA accumulation with respect to EBV-negative controls). When healthy controls are stratified for previous EBV infection (high and low, or no anti-EBNA-1 IgG titers), a direct correlation occurs with MSRV mRNA accumulation. Flow cytometry data show increased percentages of cells exposing surface HERV-Wenv protein, that occur differently in specific cell subsets, and in acute disease and past infection. Thus, the data indicate that the two main links between EBV and MS (IM and high anti-EBNA-1-IgG titers) are paralleled by activation of the potentially neuropathogenic HERV-W/MSRV. These novel findings suggest HERV-W/MSRV activation as the missing link between EBV and MS, and may open new avenues of intervention.

Abstract
Central nervous system (CNS) symptoms have been reported in clinical trials and case reports in patients receiving raltegravir. We investigated CNS symptoms in 453 HIV-infected patients. Of these 47 (10.4%) developed at least one drug-related CNS symptom. Predictors of CNS symptoms were concomitant therapy with tenofovir or with proton pump inhibitors that can increase raltegravir concentration. Thus, our data suggest a possible correlation between high raltegravir plasma concentrations and CNS symptoms, and therefore their monitoring in clinical practice.

Abstract
The clinical severity of human infection with the novel influenza virus A/H1N1v has not been completely defined, especially in HIV/hepatitis C virus (HCV) infected patients. Although most patients develop mild to moderate symptoms, severe disease may occur in a limited proportion of cases. We report the case of a 44-year-old man infected with HIV and HCV with a high CD4 cell count who developed acute respiratory distress syndrome associated with influenza virus A/H1N1v infection. The patient recovered completely after oseltamivir therapy and mechanical ventilation.

Abstract
The present study aimed to use QuantiFERON TB Gold in tube (Cellestis Limited, Carnegie, Victoria, Australia) as a tool for the screening for tubercular infection in HIV-positive patients. Seventy-three HIV-positive subjects were tested. For each individual, QuantiFERON TB in tube was performed. The immunoassay was negative in 53 subjects, positive in eight and indeterminate in 12. The data obtained indicate that factors such as the CD4 cell count and their percentage, as well as the stage of the disease, could affect the performance of the interferon-γ release assay in populations at risk such as HIV-positive subjects.

Abstract
AIM The role of leptin in bone metabolism has not yet been fully elucidated and results remain controversial. We investigated whether changes in serum leptin correlated to bone mineral density (BMD) occur in human immunodeficiency virus (HIV) patients on highly active antiretroviral therapy (HAART). METHODS The study population was 117 HIV patients (67 men, 50 women) on HAART and 50 healthy controls, all with normal body mass index (BMI). Based on whole body BMD as measured by dual energy x-ray absorptiometry (DEXA), patients were classified as having a low (< -1) T-score (L) or a normal (> -1) T-score (N); DEXA scans were also used to determine total body fat (TFM) and percent fat (F%); radioimmunologic assays were used to measure leptin, osteocalcin (OC), bone alkaline phosphatase (BAP), 1,25 (OH)2 D in serum, and pyridinium cross-links (PYD & DPD) in urine. RESULTS Of the 117 HIV patients, 54 (46.1%) were classified as L and 63 (53.9%) as N; BMD in both sexes was lower (P <0.01) among the L patients than among either the N patients or the controls; 25/32 L men and 19/22 women were osteopenic, the remaining were osteoporotic. The mean TFM, F%, OC, BAP and PYD & DPD values were higher and the mean 1,25 (OH)2 D values were lower in the L than in the N patients; leptin was higher among the L men (P <0.002) and the L women (P <0.03) than in the N patients. In both sexes. leptin positively correlated with TFM, F%, BAP and PYD & DPD; however, leptin, TFM and F% correlated negatively with BMD. A negative correlation was found between 1,25 (OH)2 D and PYD & DPD in women. At follow-up assessment of 56 HIV patients continuing HAART, leptin and BAP increased and 1,25 (OH)2 D decreased, but not significantly; BMD significantly decreased in women and PYD & DPD increased in men (P <0.02). CONCLUSIONS An inverse relationship was found between leptin and BMD in HIV patients with osteopenia/osteoporosis treated with HAART. While the role of leptin in bone metabolism in a setting of HIV is still unclear, an inhibitory effect of leptin associated with a negative action by HAART may be hypothesized.

Abstract
BACKGROUND Combination antiretroviral therapy has reduced both HIV/AIDS related morbidity and mortality. However, while the number of new AIDS diagnosis progressively declined in Europe from 1997 to 2004, new HIV infection diagnoses showed an increase since 1998. Unfortunately, there is no national HIV reporting system in Italy, and no information is available from the South and the islands. METHODS Data on new HIV infections diagnosed in northern Sardinia between 1997 and 2004 were retrospectively collected. Thus, two four years periods (1997-2000 vs 2001-2004) were compared in order to assess changes in the characteristics of newly diagnosed individuals. RESULTS Overall, 156 new HIV infection diagnoses occurred during the study period, 87 (55.8%) in males and 69 (44.2%) in females. The incidence rate per 100,000 inhabitants showed a progressive decline from 1997 (5.9) to 2001 (3.3), followed by a rapid increase in 2002 (5.0) and a new decline in 2004 (3.5). Median age progressively increased over the study period, from 33 years in 1997 to 38 in 2004. Males (55.8%) were more frequently affected than females (44.2%), who showed a trend toward a slight but progressive proportional increase. With regard to the exposure category, 95 (60.9%) individuals were heterosexual contacts, 38 (24.4%) injection drug users (IDU), 17 (10.9%) homosexual men, and 6 (3.8%) not determined (ND). There was a proportional increase for homosexual men (+7.5%) and heterosexual contacts (-7.9%), while IDU showed a slight decrease ( 2.7%). Heterosexual intercourse was the main exposure category both for women (78%) and men (47.1%), but man-to-man sex increased in the last study period. IDU still accounted for 20.3% and 27.5% of the cases among women and men, respectively. An increase in the proportion of new diagnoses in pregnant women, from 8.6% to 20.6%, was also observed. All pregnant women diagnosed in the first four years period were Italian, whereas 4 of the 7 (57.1%) women diagnosed thereafter were foreigner. Finally, the proportion of new HIV diagnoses in foreigners showed a marked increase, from 2.4% to 17.6%; of them 71.4% originated from sub-Saharan Africa. CONCLUSIONS Our results suggest that the HIV epidemic is far from being controlled in our Region. Prevention campaigns targeted to homosexual men, women and migrants are needed. Non-HIV specialists, such as gynaecologists and obstetricians, as well as general practitioners, should routinely offer HIV testing to pregnant women.

Abstract
In this work we report the first two cases of human granulocytic ehrlichiosis (HGE) in Sardinia. In early September 2004, a 69-year-old woman (patient 1) was admitted to the Infectious Diseases Institute of Sassari for rickettsiosis like-syndrome: high fever (39.5-40 degrees C), dyspnea, reduced consciousness, vomiting, and cutaneous rash. In late September 2004, a 30-year-old man (patient 2) with high fever was admitted for an evident palmar and oral erythema, edema of the labium, very intense arthralgia, myalgia, and dyspnea. In these two hospitalized patients, the diagnosis was made through indirect IgM and IgG immunofluorescent technique and confirmed by the presence of the specific DNA in the leukocytes. The two patients were A. phagocytophilum-PCR positive.

Abstract
Hepatitis C virus (HCV) variability is mainly attributed to the ability of the virus to respond to host immune pressure, acting as a driving force for the evolution of quasispecies. This study was aimed at studying the changes in HVR-1 heterogeneity and the evolution of HCV quasispecies in HIV/HCV-coinfected patients according to the pattern of response to highly active antiretroviral therapy (HAART). Sixteen HIV/HCV-coinfected patients harbouring HCV genotype 1 and who had been on HAART for at least 1 year, 8 showing increasing CD4+T-cell counts (immunological responders) and 8 showing a stable or decreasing CD4+ T-cell counts (immunological non-responders), were selected from a prospective cohort study. After 1 year of HAART, 11 patients showed HIV viral load <2.6 log10 cp/ml (virological responders), and 5 showed HIV viral load above this value (virological non-responders). Plasma samples, collected before starting therapy and after 1 year of HAART, underwent clonal sequence analysis for HVR-1 region of HCV. Non-synonymous/synonymous substitutions ratio (Ka/Ks), aminoacidic complexity (normalized Shannon entropy) and diversity (p-distance), were considered as parameters of quasispecies heterogeneity. After 1 year of HAART, heterogeneity of HVR-1 quasispecies significantly decreased in virological non-responders, whereas the heterogeneity tended to increase in virological responders. The differences in the evolution were less stringent, when considering immunological response. On the other hand, profound qualitative modifications of HVR-1 quasispecies were observed only in patients with both immunological and virological HAART response. On the whole, these findings suggest that, in patients undergoing HAART, the extent of HCV variability and the evolution of HVR-1 quasispecies is influenced by the pattern of response to antiretroviral therapy.

Abstract
A cross-sectional study was undertaken on the correlates of infection for the human immunodeficiency virus (HIV) and hepatitis viruses B and C (HBV and HCV) in a sample of inmates from eight Italian prisons. A total of 973 inmates were enrolled [87.0% males, median age of 36 years, 30.4% intravenous drug users (IDUs), 0.6% men who have sex with men (MSWM)]. In this sample, high seroprevalence rates were found (HIV: 7.5%; HCV: 38.0%; anti-HBc: 52.7%; HBsAg: 6.7%). HIV and HCV seropositivity were associated strongly with intravenous drug use (OR: 5.9 for HIV; 10.5 for HCV); after excluding IDUs and male homosexuals, the HIV prevalence remained nonetheless relatively high (2.6%). HIV prevalence was higher for persons from Northern Italy and Sardinia. The age effect was U-shaped for HIV and HCV infections; HBV prevalence increased with age. Tattoos were associated with HCV positivity (OR: 2.9). The number of imprisonments was associated with HIV infection, whereas the duration of imprisonment was only associated with anti-HBc. The probability of being HIV-seropositive was higher for HCV-seropositive individuals, especially if IDUs. In conclusion, a high prevalence of HIV, HCV, and HBV infections among inmates was observed: these high rates are in part attributable to the high proportion of IDUs. Frequency of imprisonment and tattoos were associated, respectively, with HIV and HCV positivity. Although it is possible that the study population is not representative of Italy's prison inmate population, the results stress the need to improve infection control measures users was prisons.

Abstract
The prognostic role of GB virus type C (GBV-C) viraemia in HIV-infected subjects treated with highly active antiretroviral therapy (HAART) is still undefined, The aim of this analysis is to assess the relationship between GBV-C infection and response to antiretroviral therapy among HIV-infected subjects initiating HAART when antiretroviral-naive. A prospective, observational study of 400 HIV-infected patients with measurements of GBV-C RNA, hepatitis C virus (HCV) antibodies and HCV RNA determined from plasma stored prior to HAART initiation, Time to virological (achieving HIV RNA ≤500 copies/ml) and immunological success (a CD4+ count increase of ≥200cells/μl), and the time to virological relapse (confirmed HIV RNA >500 copies/ml) were assessed by Kaplan-Meier methods and Cox proportional hazard regression model. Of the subjects, 117 (29.3%) were GBV-C positive and, overall, 351 (87.8%) patients achieved virological success, After controlling for a number of confounders including HCV RNA, GBV-C viraemic patients experienced a significantly lower risk of HIV rebound than those who were GBV-C negative [relative hazard (RH)=0.56, 95% CI: 0.34–0.93, P=0.03], Conversely, the probability of achieving initial virological success or CD4+ count response after HAART did not differ between GBV-C-negative and -positive subjects, These results suggest that GBV-C coinfection may play a role in determining the rate of HIV rebound possibly by competing with HIV replication after HIV load has been successfully suppressed by HAART.

Abstract
High level HIV-1 drug resistance in recently infected treatment-naive individuals correlates with sub-optimal virological responses to highly active antiretroviral therapy (HAART). To determine whether genotypic HIV-1 drug resistance in chronic naive patients, as interpreted by various systems, could predict the virological outcomes of HAART, isolates from patients enrolled in a prospective observational cohort (ICoNA) prior to treatment start were genotyped. Genotypic susceptibility scores (GSS) assigned to the initial HAART regimens using the interpretations of pre-therapy resistance mutations by 13 systems were related to virological outcomes. Of 415 patients, 42 (10%) had at least one major resistance mutation. According to the different interpretations, 1.9–20.5% of patients had some level of resistance to at least one drug in the initial regimen. In multivariable analysis, GSS from two systems significantly predicted the time to virological success: Rega 5.5, for each unit increase in GSS adjusted relative hazard (RH) 1.86 [95% confidence intervals (95% CI): 1.15–3.02] and hivresistanceWeb v3, RH 1.87 (95% CI: 1.00–3.48). With three other systems, GSS showed a trend towards a significant prediction of success: Retrogram 1.6, RH 2.33 (95% CI: 0.98–5.53), Menéndez 2002, RH 2.36 (95% CI: 0.97–5.72) and Stanford hivdb, RH 2.06 (95% CI: 0.94–4.49). Genotypic resistance testing coupled with adequate interpretation in chronic naive patients can usefully identify those at risk of sub-optimal virological response to HAART.

Lamivudine-treated patients (accounting for 73% of the study population) showed a significantly lower level of alanine aminotransferase over follow-up [–81.1 mU/ml mean difference; 95% confidence intervals (95% CI): –30.3; –131.7, P=0.003] and a significantly reduced risk of liver-related morbidity/mortality [Relative hazard (RH)=0.07; 95% CI: 0.01–0.38, P=0.002] than those starting a lamivudine sparing-regimen.

Abstract
AIM Given the few controversial data about the effect of highly active antiretroviral therapy (HAART) on bone mass in HIV patients, we investigated whether a relationship between osteopenia/osteoporosis risk and HAART exists. METHODS In 172 HIV patients, 152 on HAART, 92 including and 60 not including protease inhibitors (PI), 20 naïve and 64 controls, we measured spine/femur bone mineral density (BMD) by DEXA, and assayed serum osteocalcin (O), bone alkaline phosphatase (BAP), 1,25(OH)2 D, parathormone (PTH), calcium (Ca) and urinary pyridinium cross-links (PYD & DPD). RESULTS Following WHO BMD t-score criteria, osteopenia was ascertained in >35% of all HAART groups and in 30% of naive. Only HAART patients had osteoporosis, PI patients more frequently, significantly (p<0.03) in spine (21.7% vs 8.3%). Males, intravenous drug users and B-C stage patients have a higher risk for low bone mass. Mean t-score was significantly lower in both spine and femur and O and PYD & DPD higher in PI than non PI patients and controls; 1,25(OH)2 D was significantly lower in all HIV groups than controls, PI patients having the lowest values positively correlating with BMD and negatively with OC and PYD & DPD, and it decreased further in 27 non selected monitored patients continuing on HAART. PTH was higher and Ca lower in HAART patients than controls but not significantly, PTH negatively correlating with BMD. CONCLUSION HAART could be associated with osteopenia, even osteoporosis, and it could aggravate the loss in bone mass due to HIV infection itself. We hypothesize that HAART may directly affect bone remodelling and/or may indirectly affect vitamin D metabolism.

Abstract
We investigated <sup>99m</sup>Tc-tetrofosmin scintigraphy in 27 patients with Kaposi’s sarcoma: 20 had classic (CK), 5 AIDS-associated (AK) and 2 transplantation-associated (TK) variants. Twenty-three patients had clinically evident cutaneous and/or mucosal lesions, 9 of them with associated sarcomatous lymphadenopathy; 2 TK patients had only lymph nodes or other extracutaneous Kaposi sites. Both planar and SPECT <sup>99m</sup>Tc-tetrofosmin scintigraphies were performed in all cases and neck pinhole (P)-SPECT in selected patients. <sup>99m</sup>Tc-tetrofosmin uptake was observed in 88% of patients with clinically evident cutaneous and/or extracutaneous Kaposi lesions. Scintigraphy gave additional information on cutaneous lesion extent, particularly SPECT regarding deep invasion and subclinical sites in some cases. However, scintigraphy was less sensitive in the detection of small, isolated and scattered lesions. SPECT/P-SPECT were positive in 8/8 patients with sarcomatous lymph nodes, planar imaging in 5/8, ultrasonography in 7/8, while all procedures were negative in 6 other patients with reactive or HIV infection lymph nodes. SPECT demonstrated lymphadenopathy remission in 1 TK patient after immunosuppressive therapy modification and, like planar imaging, ascertained an associated lymphoma with <sup>67</sup>Ga-citrate combined. <sup>99m</sup>Tc-tetrofosmin scintigraphy, especially SPECT, can be useful both in the detection and staging of Kaposi sarcoma lesions as a complementary tool to clinical and other conventional diagnostic methods.

Abstract
BACKGROUND Despite the increased dissemination of tuberculosis among HIV infected patients, the diagnosis is difficult to establish. Traditional microbiological methods lack satisfactory sensitivity. We have developed a highly sensitive and specific nested polymerase chain reaction (PCR) capable of detecting Mycobacterium tuberculosis DNA in urine specimens and have used this test to examine urine specimens from HIV patients with active pulmonary tuberculosis. METHODS Urine specimens from 13 HIV infected patients with microbiologically proven active pulmonary tuberculosis, 10 AIDS patients with non-tuberculous mycobacterial infection (documented by blood culture), 53 AIDS patients with no evidence of mycobacterial disease, and 80 healthy subjects (25 with positive skin test to purified protein derivative) were tested for M tuberculosis using PCR, acid fast staining (AFS), and culture. RESULTS Of the urine specimens from patients with active tuberculosis, all tested positive by PCR, two by culture, and none by AFS. No reactivity was observed in urine specimens from patients with non-tuberculous mycobacterial infection. Of the 53 AIDS patients without mycobacterial infection, one had a positive urine PCR. Normal subjects were all negative. CONCLUSIONS Urine based nested PCR for M tuberculosis may be a useful test for identifying HIV patients with pulmonary tuberculosis.

Abstract
The Authors have found both IgM and antibodies for the TORCH complex in the umbilical blood of 1500 newborns. In 119 (7.9%) there was an increase of IgM. In 23% of these newborns there were present antibodies for rubella, in 21% antibodies for toxoplasma, in 15.9% antibodies for cytomegalovirus, and in 19.2% antibodies for herpes simplex. However there was no statistical correlation between the antibodies for the TORCH complex and the increase of IgM.

Abstract
The Authors investigated HBsAg in an institution for the mentally retarded. The high incidence (8.7%) in the patients and in some categories of the hospital attendants, was related with the poor hygienic conditions of the institution. Moreover it was found an endemic spread of hepatitis between the patients.

Abstract
The epidemiology of Salmonella infections in Sassari in the last four years was reported. The remarkable increase of gastroenteritis caused by uncommon Salmonella and by S. wien in 1975 and 1976 was point out: about all cases were related with 3 epidemic episodes in hospitalized patients that were notified as paratyphoid cases in 91% and as infancy's gastroenteritis in 9%. The 201 strains of Salmonella isolated from June 1975 to May 1976 belong for 91% to group B (for 80,5% to S. wien), for 2% to group C1, for 1,5% to group C2, for 5% to group D1 and for 0,5% to group E4. The hypothesis on introduction of S. wien in Sardinia were examined; the rules for limitation of Salmonella diffusion and for prevention of the endemicity of new imported strains, were examined.

Abstract
In 3828 subjects (1489 males and 2339 females) apparently healthy was investigated the presence in the serum of Australia antigen and of corrispondent antibody with electrosyneresis, the activity of the G6PD eritrocytic and the eventual condition of carrier of microcytemic tare. An incidence of HBs Ag of 1.83% (2.75% in males and 1.24% in females) without any statistically important differences in the age groups and habitual residence and also the grade of G6PD eritrocytary activity was detected. A more elevated statistical incidence was observed among the carriers of thalassemic caracter never transfused. The anti HBs Ag antibodes were observed in 0.26% of the examined subjects.
