HIV treatment and care among Italian inmates: a one-month point survey.

BACKGROUND: HIV infection, with an estimated prevalence be between 2 and 50 times those of the general adult population is a major health challenge for prison authorities worldwide. Since no nationwide surveillance system is present in Italy, data on HIV prevalence and treatment in prisons are limited to only a few and small observational studies. We aimed to estimate HIV prevalence and obtain an overview on diagnostic and therapeutic activities concerning HIV infection in the Italian penitentiary system. METHODS: We piloted a multi-centre cross-sectional study investigating the prevalence of HIV infection and assessing HIV-related medical activities in Italian correctional institutions. RESULTS: A total of 15,675 prisoners from 25 institutions, accounting for approximately one-fourth of the prison inmates in Italy, were included in the study, of whom, 97.7 % were males, 37.1 % foreigners and 27 % had a history of intravenous drug addiction. HIV-tests were available in 42.3 % of the total population, with a known HIV Infection proportion of 5.1 %. In the month prior to the study, 604 of the 1,764 subjects who entered prison were tested for HIV, with a HIV-positive prevalence of 3.3 %. Among the 338 HIV-positive prisoners, 81.4 % were under antiretroviral treatment and 73.5 % showed undetectable HIV-RNA. In 23/338 (6.8 %) a coinfection with HBV and in 189/338 (55.9 %) with HCV was also present. Among the 67 (19.8 %) inmates with HIV who did not receive HIV treatment, 13 (19.5 %) had T-CD4+ count <350 cells/mm(3) and 9 (69.2 %) of these had refused the treatment. The majority of the inmates with HIV-infection were on a PI-based (62.5 %) or on NNRTIs-based (24.4 %) regimen. Only a minority of patients received once daily regimens (17.2 %). CONCLUSIONS: Although clinical and therapeutic management of HIV infection remains difficult in Italian prisons, diagnostics, treatment and care were offered to the majority of HIV-infected inmates. Specific programs should be directed towards the prison population and strict cooperation between prison and health institutions is needed to increase HIV treatment.

Hepatitis E virus and hepatitis A virus exposures in an apparently healthy high-risk population in Italy.

PURPOSE: The prevalence of anti-hepatitis E virus (HEV) and anti-hepatitis A virus (HAV), as well as the possible links with socio-demographic and other viral risks factors, were evaluated in an inmates population. METHODS: The study population consisted of 973 consecutively recruited inmates of eight Italian prisons. RESULTS: The anti-HEV prevalence was 11.6 % (113/973). It increased significantly by age (χ(2) for linear trend: p = 0.001) and was significantly higher among non-Italian compared to Italian inmates (15.3 vs. 10.7 %, respectively). Age >40 years [odds ratio (OR) 2.1; 95 % confidence interval (CI) 1.4-3.1], non-Italian citizenship (OR 1.8; 95 % CI 1.1-2.9) and anti-HIV seropositivity (OR 2.2; 95 % CI 1.2-4.2) were the only factors independently associated to anti-HEV positivity by logistic regression analysis. The overall anti-HAV prevalence was 86.4 %, and was significantly higher in non-Italian compared to Italian prisoners (92.6 vs. 84.9 %, respectively; p = 0.02). Age older than 40 years (OR 3.6; 95 % CI 2.2-5.9), <5 years formal education (OR 2.1; 95 % CI 1.3-3.2) and non-Italian nationality (OR 2.7; 95 % CI 1.5-4.8) were factors independently associated to anti-HAV positivity by the logistic regression analysis. CONCLUSIONS: Compared to the general population, significantly higher anti-HEV and anti-HAV prevalences were observed in an inmates population in Italy. Old age and non-Italian nationality were factors independently related to both HEV and HAV exposures. This data suggest the important role of low socio-economic factors in the transmission of both infections in high-risk populations. The possible epidemiological and/or pathogenetic links between HEV and HIV exposures need to be studied further.

Blood born viral infections, sexually transmitted diseases and latent tuberculosis in italian prisons: a preliminary report of a large multicenter study.

BACKGROUND: Recent screenings of inmates for Hepatitis C virus (HCV), Hepatitis B virus (HBV), human immunodeficiency virus (HIV), Syphilis and Latent Tuberculosis (LTB) did not provide sufficient information to improve healthcare strategies. AIM: To obtain valuable information on the endemicity of the above mentioned Infections in prisons of Italy. MATERIALS AND METHODS: A screening based on a peer-to-peer communication, followed by a month of blood sampling on a voluntary basis was performed to detect antibody to 4 of the 5 above mentioned infections and detect LTB by PPD (purified protein derivative) Skin Test. The present analysis regards data obtained in 9 of the 20 prisons. RESULTS: The percentage of patients who accepted the screening varied between jails (37.3-95.2%, median 62.2), but it was higher than 10.0-20.5% obtained in the same 9 prisons using traditional methods before our intervention. The participation to the screening reached 65.3% for HBV, 64.6% for HCV, 67.4%for HIV, 55.7% for TPHA (Treponema Pallidum Hemagglutination Assay) and 42.8% for LTB. HBsAg was detected in 4.4% of 2265 subjects, anti-HCV in 22.8% of 2241, anti-HIV in 3.8% of 2339 and TPHA in 2.1% of 1932; PPD Skin Test was positive in 17.2% of 1486 subjects. The screening identified 183 subjects with an unknown infection, 56 italian and 127 foreigners to be evaluated for clinical decisions: 35 with HBV chronic infection, 34 with HCV chronic infection, 3 anti-HIV positive, 14 with syphilis and 97 with LTB. CONCLUSIONS: The new approach to the screening, based on a peer-to-peer communication followed by blood sampling on a voluntary basis provided valuable information to improve the healthcare system in each single prison.

Peculiar clinical presentation of COVID-19 and predictors of mortality in the elderly: A multicentre retrospective cohort study.

BACKGROUND: The spectrum of COVID-19 clinical manifestations is not yet known. In the elderly, mortality and extrapulmonary involvement appears more frequent than expected. METHODS: A multicentre-retrospective-case-series study of COVID-19 patients, aged ≥65 years, hospitalised between March 1 and June 15, 2020. Patients were classified at admission into 3 groups based on their Clinical Frailty Scale (CFS) score: 1-3 (group A), 4-6 (group B) and 7-9 (group C). RESULTS: Of the 206 patients in the study, 60 (29%) were assigned to group A, 60 (29%) to B and 86 (42%) to C. Significantly more frequent in group C than in B or A were: mental confusion (respectively 65%, 33%, 7%; P < 0.001), kidney failure (39%, 22%, 20%; P = 0.019), dehydration syndrome (55%, 27%, 13%; P < 0.001), electrolyte imbalance (54%, 32%, 25%; P = 0.001), and diabetic decompensation (22%, 12%, 7%; P = 0.026). Crude mortality was 27%. By multivariate logistic regression model independent predictors of death were male sex (adjusted odds ratio (aOR) = 2.87,95%CI = 1.15-7.18), CFS 7-9 (aOR = 9.97,95%CI = 1.82-52.99), dehydration at admission (aOR = 4.27,95%CI = 1.72-10.57) and non-invasive/invasive ventilation (aOR = 4.88,95%CI = 1.94-12.26). CONCLUSIONS: Elderly patients with a high CFS showed frequent extrapulmonary signs at admission, even in the absence of lung involvement. These findings, along with a high CFS, predicted a significant risk of mortality.

Drug-resistant tuberculosis in human immunodeficiency virus infected persons in Italy. The Italian Drug-Resistant Tuberculosis Study Group.

OBJECTIVE: To describe the prevalence and epidemiological-clinical characteristics of tuberculosis (TB) resistance to first-line drugs in Italian human immunodeficiency virus (HIV)-infected subjects. DESIGN: Prospective, observational multicenter (25 Centers of Infectious Diseases) study. Mycobacterium tuberculosis strains from 167 HIV co-infected subjects with TB (149 new cases, 18 relapses) were tested at a central laboratory for susceptibility to rifampin (R), isoniazid (H), pyrazinamide (Z), ethambutol (E) and streptomycin (S) and for DNA fingerprint type. Drug susceptibility results were related to patients' epidemiological, clinical and laboratory features. RESULTS: Drug resistance patterns among new TB cases were as follows: R = 1%, Z = 6%, S = 8%, H + S = 3%, S + Z = 4%. TB resistant to at least R + H (MDR-TB) was detected in 36% of new cases due to an MDR-TB outbreak which was the largest thus far in Europe, involving 7/25 participating institutions, and was demonstrated by conventional and molecular epidemiology evidence. With multivariate analysis, MDR-TB was associated with hospital exposure to MDR-TB (OR = 39.3, P < 0.001) and previous use of anti-TB drugs (OR = 9.8, P = 0.008). CONCLUSION: As drug-resistant tuberculosis in Italy is thus far relatively scarce, detection of a large MDR-TB epidemic among HIV-infected subjects was alarming. Aggressive control measures are urgently needed to prevent the spread of MDR-TB throughout the country and among the general population.

Response of severe HIV-associated thrombocytopenia to highly active antiretroviral therapy including protease inhibitors.

OBJECTIVE: To investigate the response of HIV-associated severe thrombocytopenia (STP) to highly active antiretroviral therapy (HAART) including protease-inhibitors. METHODS: In this retrospective study, 15 patients with HIV-associated STP (platelet count < 50 x 10(9)/l mostly antiretroviral experienced (13/15), underwent HAART for at least 6 months (median 21; range 6-41 months) during which the platelet (PLT) count and plasmatic HIV-RNA were monitored. The PLT response was compared to that observed in 19 patients previously treated with zidovudine (AZT) monotherapy. RESULTS: HAART induced a significant increase in the PLT count (chi(2)=10.53, P=0.01) within the third month which was sustained up to the sixth month of therapy. No STP relapse was observed among eight PLT responders followed for longer than 6 months (median 27; range 7-41 months). The PLT increase after HAART was similar to that observed with AZT monotherapy, but a greater number of HAART patients were antiretroviral-experienced. HAART determined a PLT response in 10/13 subjects whose thrombocytopenia had not improved after previous AZT monotherapy. After 6 months of HAART, a complete platelet response occurred more frequently in patients with undetectable plasma HIV-RNA levels (P=0.01). CONCLUSIONS: HAART induces a sustained PLT response in HIV-associated STP, even in antiretroviral-experienced subjects and in those with AZT-resistant thrombocytopenia. An undetectable plasma HIV viraemia induced by HAART is necessary for STP recovery.

Chlamydia trachomatis and Mycobacterium tuberculosis lung infection in an HIV-positive homosexual man.

A 31-year-old homosexual man, who was human immunodeficiency virus (HIV)-positive was admitted for fever and cough. Chest computed tomography (CT) revealed the presence of diffuse interstitial reticular nodulation, and brain nuclear magnetic resonance imaging showed the presence of nodular frontal lesions. Microscopic examination of sputum and other body fluids showed the presence of acid-fast bacilli and culture-only growth Mycobacterium tuberculosis. Serology for respiratory tract pathogens was negative except for Chlamydia. An antibody titer in the immunoglobulin G (IgG) class of 1:64 for Chlamydia pneumoniae and, unexpectedly, an antibody titer of 1:1024 for C. trachomatis were found. The patient was successfully treated with antituberculosis agents, and clarithromycin, for presumptive chlamydial infection.

A simple method to detect HIV-1 protein specificity of IgG intrathecal synthesis in HIV-1 infection.

There is currently no simple method to detect the antigen specificity of anti-HIV-1 IgG intrathecal synthesis (IS). Fifty-seven pairs of serum and corresponding CSF from 29 HIV-1 seropositive patients were adjusted to an identical concentration of total IgG and tested by a commercial HIV-1 Western Blot (WB) assay. IgG IS to a given HIV-1 protein was demonstrated when the corresponding band was present in CSF but absent or significantly less represented in serum. A total anti-HIV-1 IS was defined as the presence of an IS to one or more HIV-1 antigens. Our WB analysis of CSF and serum, compared with conventional mathematical formulas, showed a higher sensitivity in demonstrating anti-HIV-1 IgG IS. Moreover, the method disclosed which HIV-1 proteins represent the target of IgG IS. This procedure is easy to perform and therefore may represent a valuable tool to study central nervous system (CNS) involvement by HIV-1 during different stages of infection.

[Management of infections from cardiac implantable electronic devices: recommendations from a study panel]. / Diagnosi e terapia delle infezioni dei dispositivielettronici cardiaci impiantabili(CIED): raccomandazioni di un gruppo di studio.

Cardiac Implantable Electronic Device (CIED) infections are an emerging clinical issue. There are no national recommendations on the management of these infections, also due to the limited number of dedicated and high quality clinical studies. Therefore, researchers from southern Italian centres have decided to share the clinical experience gathered so far in this field and report practical recommendations for the diagnosis and treatment of adult patients with CIED infection or endocarditis. Here we review the risk factors, diagnostic issues (microbiological and echocardiographic) and aetiology, and describe extensively the best therapeutic approach. We also address the management of complications, follow-up after discharge and the prevention of CIED infections. In this regard, a multidisciplinary approach is fundamental to appropriately manage the initial diagnostic process and the comorbidities, to plan proper antimicrobial treatment and complete percutaneous hardware removal, with the key support of microbiology and echocardiography.

Correlates of hepatitis C virus seropositivity in prison inmates: a meta-analysis.

BACKGROUND: The prevalence of infection with hepatitis C virus (HCV) is higher among prison inmates compared with the general population because of the high proportion of injecting drug users (IDU). METHODS: A meta-analysis of studies on HCV infection in the correctional system was performed. The main objective was to analyse risk factors for HCV infection and to assess HCV seroprevalence and incidence in prison. RESULTS: Thirty studies were included in the meta-analysis on HCV prevalence. IDU were approximately 24 times more likely than non-IDU to be HCV positive. The odds ratio of being HCV positive was three times higher for inmates exposed to tattooing than those not exposed. The odds ratio among women was 1.44 compared with men. CONCLUSIONS: The differences in HCV seroprevalence among studies can largely be explained by differences in the proportion of inmates who are IDU and partly by differences in seroprevalence among IDU in the community. Tattooing and female gender were also associated with HCV positivity. These findings should be taken into account when planning prevention activities in prisons.

Human herpesvirus 8 and human herpesvirus 2 infections in prison population.

Incarcerated persons have high rates of infectious diseases. Few data on the prevalence of sexually transmitted diseases in prisoners are available. This multi-center cross-sectional study enrolled 973 inmates from eight Italian prisons. Demographic and behavioral data were collected using an anonymous standardized questionnaire and antibodies to HIV, HCV, HBV, HSV-2, and HHV-8 were detected in a blood sample obtained from each person at the time of the enrollment in the study. Two hundred and two out of the 973 subjects (20.7%) had antibodies against HHV-8. HHV-8-seropositive subjects were more likely to be older than 30 years with a higher educational level. HHV-8 infection was associated significantly with HBV (P < 0.001) and HSV-2 (P = 0.004) seropositivity and with previous imprisonments. Multivariate analysis showed that HHV-8 infection in Italian inmates was associated with HBV (P < 0.001) and HSV-2 (P = 0.002) seropositivity otherwise among foreigners inmates HHV-8 was significantly associated with HBV infection (P = 0.05). One hundred and eighty-six (21.2%) prisoners had anti-HSV-2 antibodies. At multivariate analysis HSV-2-positivity was significantly associated with HIV (P < 0.001) and HHV-8 infections (P = 0.003), whereas it was inversely associated with HCV infection (0.004). A relatively high seroprevalence of HHV-8 and HSV-2 among Italian prison inmates was found. The association of HHV-8 and HSV-2 infections suggest sexual transmission of these viruses among Italian prison inmates.

Correlates of Mycobacterium tuberculosis infection in a prison population.

Prisons represent a crucial setting for tuberculosis control. Currently, there is scarce information concerning Mycobacterium tuberculosis (MT) infection in European prisons, and no data are available for Italy. This study aims to describe the prevalence and correlates of MT infection in an Italian prison population. In this multicentre cross-sectional study, 1,247 inmates from nine prisons were recruited and asked to undergo questioning regarding socio-economic and demographic variables, tuberculin skin testing (TST), chest radiographs and testing for HIV, hepatitis B and hepatitis C virus infection. TST was positive in 17.9% of the 448 evaluable subjects. With multivariate logistic regression (performed among male inmates), MT infection was correlated with age (adjusted odds ratio (OR) 4.12 for inmates aged 31-40 yrs; 3.78 for those aged >40 yrs), being foreign-born (OR = 4.9), education < or =5 yrs (OR = 1.88) and length of detention (increased risk per yr: 11%). As with elsewhere in the world, the prison system in Italy features a population with an increased rate of Mycobacterium tuberculosis infection and at-risk rate for Mycobacterium tuberculosis transmission. Improved tuberculosis surveillance and control measures are deemed necessary in correctional facilities nationwide, especially for subjects with the above risk factors and those who are HIV infected, in whom the tuberculin skin testing can be misleading. The screening of entrants is particularly important to avoid undiagnosed smear-positive tuberculosis cases.

Correlates of HIV, HBV, and HCV infections in a prison inmate population: results from a multicentre study in Italy.

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.

Chronic cryptococcal meningitis in an intravenous drug addict without evidence of infection by HIV-1,2 in southern Italy.

Before the emergence of AIDS, extrapulmonary cryptococcosis was very rare. By contrast, meningeal cryptococcosis is a very common opportunistic infection in AIDS patients. We report an intravenous drug addict with cryptococcal meningitis, who was not infected with HIV and had no apparent predisposing conditions. This case, as those elsewhere described, supports the potential existence of viral agents, other than HIV-1,2 capable of encouraging the occurrence of unusual infections as have emerged during the AIDS pandemic.

Epidemiological, clinical and therapeutic evaluation of the Italian cholera epidemic in 1994.

In the period between 18 October and 4 December 1994, 12 indigenous cases of cholera were registered in the southern Italian region of Puglia, 10 of them were diagnosed in our Departments of Infectious Diseases. All patients were infected by consumption of raw fish or mussels. The patients had an elevated mean age and most were affected with systemic pathologies. The clinical course was mild and rarely complicated, although frequently the characteristic riziform diarrhoea was absent. In all patients V. cholerae serotype Ogawa biotype El Tor, was isolated; one patient was co-infected by Salmonella typhi. All strains showed resistance to cotrimoxazole and tetracycline. Nine of ten patients were treated with oral ciprofloxacin at 1 g/day for 10 days resulting in disappearance of the symptoms within a median of 36 hours and negative fecal cultures within a median of 24 hours. Our data suggest that Italy is at high risk of infection imported from nearby nations. The resistance to commonly used antibiotics for treatment of cholera and the good response to ciprofloxacin suggest including fluoroquinolones among the drugs of first choice geographical areas involved in the circulation of resistant strains of V. cholerae O1.

[Isolation of the human immunodeficiency virus (HIV) from the cerebro-spinal fluid]. / L'isolamento del virus della immunodeficienza umana (HIV) dal liquido cerebro-spinale.

The authors describe a simple and available technique for HIV isolation from cerebrospinal fluid and report preliminary results obtained. Exposed data indicate that neurological involvement occurs early in the natural history of HIV infection and that the virus may be recovered in CSF at all stages of the disease, regardless of immunological conditions of patients. Virological evaluation of CSF may be important in understanding pathogenetic aspects of HIV infection and in clinical management of infected patients.

[Technical note on the isolation of HIV from peripheral lymphomonocytes: use of PHA]. / Note tecniche sull'isolamento dell'HIV da linfomonociti periferici: impiego della PHA.

As a part of ongoing study about the role that different technical factors may play in influencing the sensibility of HIV isolation procedures, the authors have evaluated the effects of PHA stimulation of infected cells on HIV replication in cell cultures. Data presented demonstrate that the use of PHA in cell cultures for HIV isolation causes a slower viral replication and, in some cases, inhibits HIV growth.

[A case of human brucellosis caused by accidental injection of animal vaccine]. / Su un caso di brucellosi umana da puntura accidentale con vaccino animale.

The Authors describe the case of an acute brucellosis in a young veterinarian due to accidental injection of animal vaccine. The past history of the patient and the serological follow-up of the animals contacted by the professional did not evidence other risk contacts. The case evidence the real possibility that attenuated Brucella melitensis strains used in animal's vaccination can represent a source of occupational risk for this infection. In addition, it is important to notify similar cases to monitor the real extent of this phenomenon.

[Acquired immunodeficiency syndrome and pulmonary Mycobacterium xenopi infection. Role of computerized tomography]. / Sindrome da immunodeficienza acquisita e malattie polmonari da Mycobacterium xenopi. Ruolo della Tomografia Computerizzata.

INTRODUCTION: Mycobacterium xenopi is one of the most common agents responsible for nontubercular mycobacterial pulmonary disease on AIDS patients. These lesions have been studied with conventional radiography, while CT has been used in patients with aspecific mycobacterioses or non-AIDS pulmonary conditions from Mycobacterium xenopi. PURPOSE: We investigated the yield of CT in the study of lung lesions from Mycobacterium xenopi in AIDS patients. MATERIAL AND METHODS: We examined 12 AIDS patients with pulmonary lesions from Mycobacterium xenopi, patients age ranged 30 to 46 years. All patients had CD4 blood levels lower than 250 cells/mL and Mycobacterium xenopi in the sputum. All patients underwent a standard chest radiograph and a CT examination. CT images were evaluated by three radiologists independently and the definitive diagnosis was made in the presence of a fourth radiologist. RESULTS: Chest CT showed parenchymal consolidation in 66% of cases, associated with bilateral basal bands in 16% of cases. Consolidation was unilateral in 41% of cases and most frequently involved the right lower lobe. Bilateral reticular interstitial involvement was seen in the patients (41%). Micronodules in 1 patient (8%) and mediastinal adenopathy in 33% of cases. Two patients had pre-xisting emphysema and 1 had bronchiectasis. DISCUSSION AND CONCLUSIONS: The frequency of lung disease from Mycobacoerium xenopi has increased because of the spreading of the HIV infection. Such lung lesions in AIDS patients are aspecific in appearance and localization, which the clinical radiologist needs to consider to address treatment planning. The frequent finding of parenchymal consolidation and the absence of cavitary lesions may be referred to the poor capability of AIDS to produce an adequate inflammatory response. The lung lesions tend to distribute in the lower lobes unilaterally. Adenopathy was also a frequent finding. CT plays a fundamental role in studying the chest of these patients because it permits to locate lung lesions with higher accuracy than conventional radiography and to detect adenopathies, micronodules reticular interstitial involvement and bronchiectases.
