Men who have sex with men often do not reveal their sexual practices or sexual orientation to their physician. Lack of disclosure from the patient, discomfort or inadequate training of the physician, perceived or real hostility from medical staff, and insufficient screening guidelines limit preventive care. Because of greater societal stresses, lack of emotional support, and practice of unsafe sex, men who have sex with men are at increased risk for sexually transmitted diseases (including human immunodeficiency virus infection), anal cancer, psychologic and behavioral disorders, drug abuse, and eating disorders. Recent trends indicate an increasing rate of sexual risk-taking among these men, particularly if they are young. Periodic screening should include a yearly health risk and physical assessment as well as a thorough sexual and psychologic history. The physician should ask questions about sexual orientation in a nonjudgmental manner; furthermore, confidentiality should be addressed and maintained. Office practices and staff should be similarly nonjudgmental, with confidentiality maintained. Targeted screening for sexually transmitted diseases, depression, substance abuse, and other disorders should be performed routinely. Screening guidelines, while inconsistent and subject to change, offer some useful suggestions for the care of men who have sex with men.

The American Academy of Pediatrics strongly encourages the disclosure of HIV status to school-age children and further recommends that adolescents know their HIV status. Limited information exists on the impact of disclosure. We designed and implemented a disclosure model hypothesized to be associated with healthy psychological adjustment and improved medication adherence. We report the model's design and implementation and results of a quasi-experimental study of the disclosure's effects on health care professionals (n = 16), caregivers (n = 39), and HIV-infected youth (n = 40) in Puerto Rico. Information was collected from youth, caregivers, and professionals by semistructured interviews and questionnaires. Most youth (70%) had feelings of normalcy 6 months post-disclosure, and most also improved their adherence to therapy after disclosure as reported by both patients (58%) and caregivers (59%). Eighty-five percent of youth and 97% of caregivers considered disclosure a positive event for themselves and their families. Fewer health care professionals reported feelings of fear, discomfort, and insecurity after protocol participation.

A double scenario characterizes the epidemiology of HIV infection in children. In countries where highly active antiretroviral therapy (HAART) is available, the pattern of HIV infection is evolving into that of a chronic disease, for which control strictly depends on patients' adherence to treatment. In developing countries with no or limited access to HAART, AIDS is rapidly expanding and is loaded with a high fatality ratio, due to the combined effects of malnutrition and opportunistic infections. The digestive tract is a target of the disease in both settings. Opportunistic infections play a major role in children with severe immune impairment, with Cryptosporidium parvum being the leading agent of severe diarrhea. Several therapeutic approaches are effective in reducing fecal output, but the eradication of the parasite is rarely obtained. Other opportunistic infections may induce severe and protracted diarrhea, including atypical mycobacteria and cytomegalovirus. Diagnosis of diarrhea should be individually tailored based on presenting symptoms and risk factors. A stepwise approach is effective in limiting patient discomfort and minimizing the costs of investigations, starting with microbiologic investigation and proceeding with endoscopy and histology. Aggressive treatment of infectious diarrhea is required in severely immunocompromised children. However, antiretroviral therapy prevents the development of severe cryptosporidiosis. The liver and pancreas are also target organs in HIV infection, although functional failure is rare. The digestive-absorptive functions are impaired, with steatorrhea, nutrient malabsorption, and increased permeability occurring in 20-70% of children. Intestinal dysfunction contributes to growth failure and further immune derangement, leading to wasting, the terminal stage of AIDS. Nutritional management is crucial in HIV-infected children and is based on aggressive nutritional rehabilitation through enteral or parenteral routes and micronutrient supplementation.HIV may play a direct enteropathogenic role and is implicated in both diarrhea and intestinal dysfunction. This explains the efficacy of antiretroviral therapy in inducing remission of diarrhea and restoring intestinal function. Gastrointestinal side effects of antiretroviral drugs are increasingly observed; they are often mild and transient. Severe reactions are rare but require the withdrawal of drugs. In conclusion, severe enteric infections and intestinal dysfunction characterize the intestinal involvement of HIV infection. This is more common in, but not limited to, children who do not receive effective antiretroviral therapy. Diagnostic approaches include microbiologic and morphologic examinations and assessment of digestive processes, but immunologic and virologic data should be also carefully considered. Treatment is based upon specific anti-infectious drugs, antiretroviral therapy, and nutritional rehabilitation.

The TORO 1 and TORO 2 clinical trials compared the efficacy and safety of enfuvirtide in combination with an optimized background antiretroviral regimen and optimized background regimen alone in HIV-1 infected patients. The patients had had previous treatment with each of the three classes of antiretroviral drugs and had a plasma level of HIV-1 RNA above 5000 copies/ml at baseline. They were randomly assigned in a 2:1 ratio to receive either enfuvirtide (90 mg subcutaneously twice daily) plus a background regimen optimized with the aid of resistance testing, or an optimized antiretroviral regimen alone (control group). Six hundred and sixty-one patients were enrolled in the enfuvirtide arm and 334 in the control group. The median baseline plasma HIV-1 RNA level was 5.2 log10 copies/ml in the enfuvirtide group and 5.1 log10 copies/ml in the control group. Patients had a median of 7 years of previous antiretroviral treatment. The optimized background regimen comprised a mean of 4 antiretroviral drugs in both groups. At week 48, the mean reduction in viral load was -1.48 log10 copies/ml in the enfuvirtide group, and -0.63 log10 copies/ml in the control group (difference = 0.846 log10 copies/ml, IC95%: -1.066; -0.626. p < 0.0001). The mean increase in the CD4+ cell count was significantly greater in the enfuvirtide group (91 cells/mm3) than in the control group (45 cells/mm3). Injection site reactions were the main reported adverse event which occurred in 98% of the enfuvirtide patients. Most had mild to moderate pain or discomfort not requiring analgesic or limiting usual activities.

HIV infection among racial and ethnic minorities is an ongoing health crisis. The disproportionate impact of HIV infection on racial and ethnic minorities has affected communities already struggling with many social and economic challenges, such as poverty, substance abuse, homelessness,unequal access to health care, and unequal treatment once in the health care system. Superimposed on these challenges is HIV infection, the transmission of which is facilitated by many of these factors. Although the epidemic is disproportionately affecting all racial and ethnic minorities, within these minority populations women are particularly affected. The care and management of racial and ethnic minorities who have HIV infection has been complicated by the unequal access to health care and the unequal treatment once enrolled in health care. Health insurance status, lack of concordance between the race of the patient and the provider, and satisfaction with the quality of their care all impact on treatment outcomes in this population. In addition, the provider must be aware of the many comorbid conditions that may affect the delivery of care to minority patients living with HIV infection: depression, substance and alcohol abuse, and posttraumatic stress disorders. The impact of these comorbid conditions on the therapeutic relationship, including treatment and adherence, warrants screening for these disorders and treating them when identified. Because the patient provider relationship has been repeatedly identified as a predictor of higher adherence, developing and maintaining a strong therapeutic alliance is critical. Participation of racial and ethnic minorities in HIV clinical trials, as in other disease states, has been very poor. Racial and ethnic minorities have been chronically underrepresented in HIV clinical trials, despite their overrepresentation in the HIV epidemiology. This underrepresentation seems to be the result of a combination of factors including (1) provider bias in referring to clinical trials, (2) mistrust of clinical research, (3) past poor experience with the health care system, and (4) the conspiracy theories of HIV disease. The paucity of minority health care professionals and minority investigators in HIV research further affects minority participation in clinical research. To improve racial and ethnic minority participation in clinical trials a sustained effort is necessary at multiple levels. Increased recruitment and retention is an ongoing need, and one that will not be satisfactorily addressed until there are better community-academic and research partner-ships, and the research questions posed also address issues of concern and significance to the affected community. Reduction in barriers to participation in clinical trials, especially given the many competing needs of racial and ethnic minority patients, is also needed. Multidisciplinary HIV care teams and research staff with training in cultural competency and cultural sensitivity may also be helpful. Prevention of HIV infection remains essential, especially among those seeking care for HIV infection. Despite several published recommendations for the inclusion of HIV prevention in the clinical care setting, studies have documented how few providers actually achieve this goal, especially those who care for disadvantaged patients. Although there are many barriers to discussing HIV risk behaviors and prevention strategies in an office visit,including time constraints and potential provider discomfort in discussing these matters, clinical visits represent an important opportunity to reinforce HIV prevention and possibly decrease further HIV transmission.

This study assessed the programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in 75 countries in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean. Multiple databases and expert recommendations were used to identify one major HIV-prevention NGO in the capital or a large city in each country, and in-depth interviews were conducted with each NGO Director. Most NGOs are carrying out their programmes with minimal funding and few regularly employed personnel. Most are highly dependent on international donors, but reliance on small grants with short funding periods limits programme development capacity. HIV-prevention activities varied by region, with African NGOs most likely to use peer education and community awareness events; Eastern European NGOs most likely to offer needle exchange; Latin American NGOs to have resource centres and offer risk reduction programmes; and Caribbean organizations to use mass education approaches. Across regions, NGOs most often targeted the general public and youth, although specialized at-risk groups were the additional focus of attention in some regions. Limited funding, governmental indifference or opposition, AIDS stigma, and social discomfort discussing sex were often cited as barriers to new HIV-prevention programmes. NGOs are critical service providers. However, their funding, programmes, and resource capacities must be strengthened if NGOs are to realize their full potential in HIV prevention.

This paper reports on the breaking of agreements between regular partners among HIV-negative gay men in Sydney. Data were from the 1333 men completing face-to-face interviews through December 2003 for the Health in Men (HIM) open cohort of HIV-negative gay men in Sydney.822 men had a primary regular partner during the six month period before their 2003 interview. Most of these men had entered into agreements with their partners about sex either with each other or with other partners (87.2%). They most commonly agreed not to use condoms with each other (50.6%). Regarding casual sex, they most commonly agreed to always use condoms (34.2%) or to have no sex with men outside their relationships (28.6%). 48.8% reported some discomfort discussing with their partner their sex outside the relationship. Among those with agreements with their partners, 27.7% reported ever breaking those agreements. Those who found it more difficult to discuss issues of HIV serostatus and sexuality were more likely to report having broken their agreements (p<.001; p=.021 at one-year follow-up) and were more likely to have engaged in unprotected anal intercourse with casual partners (p<.001). A third of those men who broke their agreements did not inform their partner. A substantial proportion of gay men with agreements with their regular partners report some discomfort discussing sexuality and HIV serostatus with their partners. Difficulty discussing these issues may place these men at increased risk of breaking their agreements and may place both themselves and their partners at increased risk of infection.

Lipodystrophy (LD) includes morphologic changes that are distressing to patients with HIV. We tested the validity of an Italian version of the Assessment of Body Change and Distress (ABCD) questionnaire and analysed its relationship to physical and mental aspects of Health-Related Quality of Life. Two hundred and fifty-two patients completed the questionnaires. Construct validity of the ABCD was tested against the MOS-HIV Health Survey, body mass-index (BMI) and CD4+ T-lymphocyte counts. Cronbach's alpha for the ABCD total score was 0.94. The ABCD showed the hypothesized moderate correlations to MOS-HIV scales and clinical variables. Preliminary evidence supports the reliability and validity of the Italian version of the ABCD in people with HIV and LD. This questionnaire may be useful to identify people experiencing greater impact of LD, or to evaluate the impact of interventions to treat LD such as plastic surgery.

Misconceptions about HIV/AIDS among Latino adults (N = 454) in California were examined using data from a population-based telephone survey conducted in 2000. Common misconceptions concerning modes of HIV transmission included transmission via mosquito or animal bite (64.1%), public facilities (48.3%), or kissing someone on the cheek (24.8%). A composite misconceptions score was constructed. Correlations between the composite measure and other HIV/AIDS-related beliefs were examined. Latinos with a higher level of misconceptions were more likely to report higher self-perceived risk of HIV infection, and discomfort with infected individuals in a school and in a food setting. Results from multiple linear regression analysis indicated that individuals 45 years and older, those who were interviewed in Spanish, and those with lower education or income levels had a higher degree of misconceptions. The results suggest the need for targeted education efforts to reduce HIV/AIDS misconceptions among Latino adults in California.

Based on limited evidence, use of intrauterine devices (IUDs) is not contraindicated for women with HIV/AIDS (strength of recommendation [SOR]: C), multiple sexual partners (SOR: C), previous actinomyces colonization (SOR: C), most types of fibroids (SOR: C), or previous ectopic pregnancy (SOR: C). The risk to IUD users of pelvic inflammatory disease (PID) is similar to women using no contraception (SOR: B). Nulliparous women may experience increased insertion discomfort and higher rates of expulsion (SOR: B). IUD use of <3.5 years is not associated with decreased fertility (SOR: B).
