Gender medicine is now an approach that can no longer be neglected and must be considered in scientific research. We investigated the systemic and mucosal immune response in a population of women living with HIV (WLWH) who were receiving successful ART and the sexual and psychological repercussions of HIV infection on the women's health. As control group, healthy women (HW) matched for age and sex distribution, without any therapy, were included. In summary, our study highlighted the persistence of immune-inflammatory activation in our population, despite virological suppression and a normal CD4 cell count. We found a hyperactivation of the systemic monocyte and an increase in inflammatory cytokine concentrations at the systemic level. The analysis carried out showed a significantly higher risk of HPV coinfection in WLWH compared to HW. Furthermore, our data revealed that WLWH have a profile compatible with sexual dysfunction and generalized anxiety disorders. Our study underlines that patients living with HIV should be evaluated by multidisciplinary teams. These findings also support the idea that more and different immunological markers, in addition to those already used in clinical practice, are needed. Further studies should be carried out to clarify which of these could represent future therapy targets.

Objective: To design a Health-related Quality of Life (HRQoL) instrument for HIV-infected people in the era of highly active antiretroviral therapy (HAART)., Methods: The self-administered questionnaire was developed by an Italian network including researchers, physicians, people living with HIV, national institutions and community-based organizations (CBO) through several steps: (1) review of existing HRQoL literature and questionnaires for HIV-infected people; (2) selection of relevant domains measuring HRQoL in HIV-infected people, and identification of new domains related to new aspects of HRQoL concerning HAART-treated individuals; (3) conduction of two pre-test analyses in independent groups of Italian HIV-positive people (n approximately =100) distributed throughout the country. The objectives of the first pre-test were to verify the usefulness of the questionnaire, to construct a form easily understandable by everyone, to define the domains and their significance; the second pre-test aimed at evaluating and reshaping the questionnaire based on a statistical analysis of the outcomes of first pre-test; (4) validation analysis. A large cohort of people with HIV infection was recruited for the last step., Results: The internal consistence reliability (Cronbach's alpha) was >or=0.70 for all domains. Most domains had Cronbach's coefficient >0.80. All domains demonstrated convergent and discriminant validity. The final version of ISSQoL includes two sections: HRQoL Core Evaluation Form (9 domains) and Additional Important Areas for HRQoL (6 domains). The ISSQoL was administered together with two additional forms: a Daily Impact of Symptoms Form and a Demographic Information Form. The Additional Important Areas for HRQoL include social support, interaction with medical staff, treatment impact, body changes, life planning, and motherhood/fatherhood., Conclusion: The data reported in the present paper provide preliminary evidence of the reliability and validity of the ISSQoL questionnaire for the measurement of HRQoL in HIV-infected people. The direct involvement of HIV-positive people in all the phases of the project was a key aspect of our work.

Two cases of community-acquired septicemia caused by serotype-O1 Yersinia pseudotuberculosis were diagnosed in middle-aged, HIV-positive, immunodeficient patients during an 8-month period. Bacterial isolates were genetically indistinguishable, but no epidemiologic link between the 2 patients was established. HIV-related immunosuppression should be regarded as a risk factor for Y. pseudotuberculosis septicemia.

In the era of new antiretroviral treatments that have dramatically reduced both morbidity and mortality, a primary goal is to maximize function and wellbeing in the everyday life of HIV-infected patients. To be able to do so, it would be important for clinicians and policy makers to identify factors that influence health-related quality of life (HRQoL). The objective of this multicentre prospective cohort study was to identify determinants of HRQoL in a cohort of Italian HIV-infected patients, the majority of whom were taking highly active antiretroviral therapy (HAART). A total of 809 patients were enrolled. The MOS-HIV Health Survey (summarized using two scores, physical health (PHS) and mental health (MHS)), and an HIV-related symptom scale were administered at enrolment and six months later. At baseline, low CD4+ cell count, hospitalization during the three months before the enrollment and symptoms were independently related to poor PHS; hospitalization during the three months before the enrollment, symptoms and poor satisfaction with information from providers were independently related to MHS. Predictors of PHS at six months included the stage of HIV infection, baseline CD4+ cells count, PHS and symptom score; while age, baseline MHS, symptom score and education predicted six-month MHS. Among these factors, symptoms, recent hospitalization and satisfaction with information are most amenable to clinical intervention.

A number of metabolic disorders, including hypercholesterolemia, hypertriglyceridemia, insulin resistance, elevated fasting glucose and diabetes mellitus, were reported in a high proportion of HIV-infected patients receiving highly active antiretroviral therapy (HAART). Less frequently, coagulative disorders were described in patients receiving HAART. Since all these metabolic disorders may predispose to coronary heart disease, an early evaluation and treatment is advisable. Existing guidelines for uninfected patients may be applied, taking into account, however, the potential for drug interactions and accumulated toxicity. It may be helpful to stratify all patients in three risk groups to plan regular diagnostic screening. Treatment of dyslipidemia and diabetes mellitus should include a first-line approach with non-pharmacological interventions. Statins and fibrates are proposed for HIV-infected patients with HAART-related hyperlipidemia, but concern has been raised on their potential for interaction with antiretrovirals and hepatic and muscle toxicity. Metformin and thiazolidenediones (or glitazones), hypoglycemic agents that increase insulin sensitivity, are presently under evaluation in diabetic and glucose-intolerant HIV-infected patients treated with HAART. Glitazones also have a potential for ameliorating the lipodystrophic syndrome. The routine evaluation of coagulative parameters is probably not advisable until a benefit of widespread screening is assessed in prospective studies. A heightened awareness of the possiblity of coagulative disorders, together with controlled trials and basic research, is needed.

The clinical management of HIV-infected individuals is based on highly active antiretroviral combination therapy, which provides significant clinical benefit in most patients, but causes in a high proportion of them a metabolic syndrome that includes body fat redistribution, hypercholesterolemia, hypertriglyceridemia, and insulin resistance. These effects are particularly evident in patients treated with protease inhibitors. It is likely that the metabolic disorders related to anti-HIV treatment will eventually translate into an increased cardiovascular risk in patients submitted to such regimens.

The advent of potent antiretroviral drugs in recent years has had an impressive impact on mortality and disease progression in HIV-infected patients, so that issues related to long-term effects of drugs are of growing importance. Hyperlipidemia, hyperglycemia, and lipodystrophy are increasingly described adverse effects of highly active antiretroviral therapy (HAART), in particular when protease inhibitors are used. Hyperlipidemia is strikingly associated with the use of most available protease inhibitors, with an estimated prevalence of up to 50%. Because of the short observation period and the small number of cardiovascular events, epidemiological evidence for an increased risk of coronary heart disease in HIV-infected patients treated with HAART is not adequate at present; however, it is likely that shortly more data will accumulate to quantify this risk. Before starting HAART and during treatment it is reasonable to evaluate all patients for traditional coronary risk factors, including lipid profile. Among the drugs that are currently used in HIV+ patients, antibacterials, antifungals, psychotropic drugs and anti-histamines have been associated with QT prolongation or torsade de pointe, a life-threatening ventricular arrhythmia. Among the risk factors that may precipitate an asymptomatic electrocardiographic abnormality into a dangerous arrhythmia is the concomitant use of drugs that share the CYP3A metabolic pathway. Since most protease inhibitors are potent inhibitors of CYP3A, clinicians should be aware of this potentially dangerous effect of HAART. Anthracyclines are potent cytotoxic antibiotics that have been widely used for the treatment of HIV-related neoplasms. Their cardiotoxicity is well known, ranging from benign and reversible arrhythmias to progressive severe cardiomyopathy. The increased survival and quality of life of HIV+ patients emphasize the importance of a high awareness of adverse drug-related cardiac effects.

Objective: To evaluate short-term toxicity from and discontinuation of antiretroviral combination prophylaxis in HIV-exposed individuals in Italy., Design: Longitudinal, open study conducted by prospective collection of data in the National Registry of PEP., Setting: All the Italian centres dedicated to HIV related care and licensed by the Ministry of Health to dispense antiretroviral drugs., Study Population: Health care workers and other persons consenting to be treated with post exposure prophylaxis (PEP) after exposures to HIV., Results: Until October, 2000, 207 individuals receiving two nucleoside reverse transcriptase inhibitors (NRTIs), and 354 receiving two NRTIs plus a protease inhibitor (PI) were enrolled. More individuals experienced side-effects in the 3-drug group (53% and 62%, respectively; OR 0.68, (95% CI 0.48-0.98), p < 0.03). However, the proportion of individuals discontinuing prophylaxis because of side-effects did not differ significantly between the 2 groups (21% and 25% respectively; OR 0.82 (95% CI 0.53-1.26); p=0.4). The 43 individuals in the 2 NRTI group discontinued PEP after a mean of 10.4 days of treatment (median 8, range 1-27), similarly to the 88 discontinuations observed in the 3-drug group (mean duration 10.5 days, median 7.5, range 1-26). Type and incidence of specific adverse effects were similar to those reported in the literature., Conclusion: Our study indicates that the difference in the proportion of individuals developing side effects and discontinuing PEP is not significant. The rate of discontinuation because of protease inhibitor side-effects does not justify per se the initial use of a less potent PEP regimen. We suggest initiating PEP with a three-drug regimen and discontinuing the protease inhibitor in the case of adverse effects.

To study the prevalence, intensity, and quality of pain in patients with human immunodeficiency virus (HIV) infection and to evaluate factors influencing the different components of pain, a self-administered multidimensional pain questionnaire (Italian Pain Questionnaire [IPQ]) was administered to 153 HIV patients admitted to the Department of Infectious Diseases of a teaching hospital over a 7-month period. Ninety-three (60.8%) patients experienced pain for a total of 131 pain sites. The intensity and the nonsensorial components of pain were greater in ward patients compared to outpatients. In 70% of pain syndromes it was not possible to define the etiology at the time of the visit. Pain was observed more frequently in intravenous drug users (IDUs) (72.9%) compared to patients with other HIV modalities of transmission (50.6%) (p = 0.008). The mean value of sensory class was greater in patients who were not IDUs. Within IDUs group there was a predominance of descriptors of the affective class over the sensory class. The prevalence of pain is high in HIV-infected individuals. The different components of pain are influenced by the modality of transmission and the setting of care. The assessment of scores of different components of pain could help to select and monitor appropriate interventions in pain control.

Objective: To assess rates of prescriptions of protease inhibitors (PI) and determinants of not being prescribed PIs in a cohort of HIV-infected people eligible (according to published guidelines) for highly active antiretroviral therapy (HAART)., Design: Cross-sectional survey., Methods: A total of 684 patients with CD4+ counts <500 cells/microl were enrolled from seven Italian HIV treatment centers from October 1997 to April 1998. A questionnaire on health-related quality of life (MOS-HIV) and patient ratings of the quality of care was administered. Sociodemographic variables, HIV disease-related factors, and prescribed antiretroviral therapy were also recorded., Results: 61% of those enrolled were prescribed PI (median, 7.5 months). In addition, 75% of patients had previously received antiretroviral therapy. Fewer than 1% were prescribed nonnucleoside reverse transcriptase inhibitors (NNRTIs). Using multivariable logistic regression considering those with CD4+ counts <500 cells/microl, patients reporting the least information received (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.23-2.58), injecting drug users (IDUs; OR, 1.73; 95% CI, 1.18-2.54), people with CD4+ counts >200 cells/microl (OR, 1.76; 95% CI, 1.19-2.61), and patients with early stage disease (OR, 2.24; 95% CI, 1.73-2.90) were less likely to have be prescribed PIs., Conclusions: Of patients eligible for HAART, only 61% were prescribed PIs. People who wanted more information, IDUs, and patients in earlier disease stages are significantly less likely to be prescribed PIs. Access to HAART remains a critical issue in the management of HIV disease.

The Karnofsky Scale of Performance Status (KPS) is a measure of health status that is widely used for HIV-infected persons, although few studies have documented its reliability and validity for HIV. We developed a modified KPS in an attempt to make it more appropriate for use in HIV-infected persons and evaluated its inter-rater reliability in a multicenter study. Patients (N = 657) were recruited from five hospitals in three Italian cities; responses were scored using the modified scale by three different raters in each hospital: one experienced physician, one young physician, and one nurse. Kendall's correlation test showed a strong inter-rater agreement for the total of observations: 0.82 between the two physicians, 0.77 between the experienced physician and the nurse, and 0.76 between the young physician and the nurse. The analysis of variance showed a strong effect of the stage of the disease on the KPS score. The specific hospital had little effect, whereas the effect of the type of rater disappeared when the nurse was excluded from the analysis. This modified scale demonstrated a good reliability, although training of raters could help to eliminate differences among raters and among hospitals.

We investigated the prevalence and intensity of symptoms and the use of drugs for symptom control among all HIV-infected patients reporting to the outpatient clinics or wards of 15 clinical centres in central Italy, recording clinical and epidemiological data on three consecutive days. A total of 1128 patients were observed and tabulated. Their most frequent symptoms were asthenia (65%), anorexia (34%), cough (32%), pain (29%), and fever (29%). Opioid analgesics were used in 3% of these patients and non-opioid analgesics in 13%. A large majority of HIV-infected patients presented with symptoms regardless of the stage of their disease. Pain was present in fewer than one third of patients but nonetheless seemed to be undertreated. Pain was more frequent and more intense among intravenous drug users. Based on our study, a greater effort to control symptoms in HIV patients seems to be warranted.

The purpose of this study is to retrospectively review the clinical, radiographic and laboratory characteristics, the therapy and evolution of sinusitis in HIV-infected patients hospitalized between January 1, 1985 and July 31, 1994. We have observed 65 cases of sinusitis in 58 HIV-infected patients (77.6% classified as group C). Forty-five of 65 cases (69.2%) showed radiographic evidence of acute sinusitis; the remaining 20 cases (30.8%) showed chronic sinusitis. In 61 cases (93.8%) there were symptoms related to sinusitis. In 61 sinusitis cases antibiotics were administered. Although the majority of patients responded at least partially to antibiotic therapy, a complete resolution of clinical and radiographic signs was observed in only 47.4% of acute sinusitis cases. No resolution was observed in chronic sinusitis after treatment stop. Sinusitis appears to occur quite frequently in HIV-infected patients, is often related to non-specific symptoms, may be recurrent and is commonly refractory to treatment.
