Prevention and treatment of opportunistic infections in HIV-infected adults and adolescents: Updated Guidelines from the Centers for Disease Control and Prevention, National Institutes of Health, and HIV Medicine Association of the Infectious Diseases Society of America.

In May 2013, a revised and updated version of the Centers for Disease Control and Prevention/National Institutes of Health/HIV Medicine Association Guidelines for Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents was released online. These guidelines, since their inception in 1989, have been widely accessed in the United States and abroad. These guidelines have focused on the management of HIV/AIDS-related opportunistic infections that occur in the United States. In other parts of the world, the spectrum of complications may be different and the resources available for diagnosis and management may not be identical to those in the United States. The sections that have been most extensively updated are those on immune reconstitution inflammatory syndrome, tuberculosis, hepatitis B, hepatitis C, human papillomavirus, and immunizations. The guidelines will not be published in hard copy form. This document will be revised as needed throughout each year as new data become available.

Topical penile microbicide use by men to prevent recurrent bacterial vaginosis in sex partners: a randomized clinical trial.

BACKGROUND: Bacterial vaginosis (BV) recurs frequently after metronidazole treatment. This randomized, single-masked clinical trial evaluated the efficacy of topical application of 62% ethyl alcohol in emollient gel (gel) to the penis by male partners of women diagnosed with BV for preventing post-treatment BV recurrence. METHODS: Among 587 Kenyan women presenting with vulvovaginal symptoms, 236 had BV (vaginal Gram stain Nugent score >=7), of whom 223 (94.3%) agreed, along with their partners, to be randomized: 115 to the intervention and 108 to the control arm. In the intervention arm, male partners agreed to apply gel each morning, and before and after sexual intercourse. All couples received counseling, condoms, and syndromic treatment of sexually transmitted infection symptoms. Follow-up visits were scheduled 1 week, 1 month, and 2 months postenrollment, with vaginal Gram stains at every visit and culture for H2O2-producing lactobacilli at the 2-month visit. The primary outcome was time to diagnosis of BV during follow-up. RESULTS: In the primary intent-to-treat analysis, diagnosis of BV was significantly more frequent in the intervention arm (hazard ratio: 1.44, 95% confidence interval: 1.01­2.04). After adjustment for baseline covariates, the hazard ratio was 1.39 (95% confidence interval: 0.98­1.99). At the 2-month visit, prevalences of any vaginal lactobacilli or of H2O2-producing lactobacilli did not differ appreciably in the 2 study arms (P = 0.81 and 0.32, respectively). CONCLUSION: Daily use of the 62% ethyl alcohol gel by men before and after sex significantly increased persistence or early recurrence of BV in their partners through 2 months after metronidazole treatment. However, no difference was observed in prevalences of vaginal lactobacilli within this same period.

Guidelines for prevention and treatment of opportunistic infections in HIV-infected adults and adolescents: recommendations from CDC, the National Institutes of Health, and the HIV Medicine Association of the Infectious Diseases Society of America.

This report updates and combines earlier versions of guidelines for the prevention and treatment of opportunistic infections (OIs) in HIV-infected adults (i.e., persons aged >/=18 years) and adolescents (i.e., persons aged 13--17 years), last published in 2002 and 2004, respectively. It has been prepared by the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH), and the HIV Medicine Association (HIVMA) of the Infectious Diseases Society of America (IDSA). The guidelines are intended for use by clinicians and other health-care providers, HIV-infected patients, and policy makers in the United States. These guidelines address several OIs that occur in the United States and five OIs that might be acquired during international travel. Topic areas covered for each OI include epidemiology, clinical manifestations, diagnosis, prevention of exposure; prevention of disease by chemoprophylaxis and vaccination; discontinuation of primary prophylaxis after immune reconstitution; treatment of disease; monitoring for adverse effects during treatment; management of treatment failure; prevention of disease recurrence; discontinuation of secondary prophylaxis after immune reconstitution; and special considerations during pregnancy. These guidelines were developed by a panel of specialists from the United States government and academic institutions. For each OI, a small group of specialists with content-matter expertise reviewed the literature for new information since the guidelines were last published; they then proposed revised recommendations at a meeting held at NIH in June 2007. After these presentations and discussion, the revised guidelines were further reviewed by the co-editors; by the Office of AIDS Research, NIH; by specialists at CDC; and by HIVMA of IDSA before final approval and publication. The recommendations are rated by a letter that indicates the strength of the recommendation and a Roman numeral that indicates the quality of evidence supporting the recommendation, so that readers can ascertain how best to apply the recommendations in their practice environments. Major changes in the guidelines include 1) greater emphasis on the importance of antiretroviral therapy for the prevention and treatment of OIs, especially those OIs for which no specific therapy exists; 2) information regarding the diagnosis and management of immune reconstitution inflammatory syndromes; 3) information regarding the use of interferon-gamma release assays for the diagnosis of latent Mycobacterium tuberculosis (TB) infection; 4) updated information concerning drug interactions that affect the use of rifamycin drugs for prevention and treatment of TB; 5) the addition of a section on hepatitis B virus infection; and 6) the addition of malaria to the list of OIs that might be acquired during international travel. This report includes eleven tables pertinent to the prevention and treatment of OIs, a figure that pertains to the diagnois of tuberculosis, a figure that describes immunization recommendations, and an appendix that summarizes recommendations for prevention of exposure to opportunistic pathogens.

Global health in medical education: a call for more training and opportunities.

Worldwide increases in global migration and trade have been making communicable diseases a concern throughout the world and have highlighted the connections in health and medicine among and between continents. Physicians in developed countries are now expected to have a broader knowledge of tropical disease and newly emerging infections, while being culturally sensitive to the increasing number of international travelers and ethnic minority populations. Exposing medical students to these global health issues encourages students to enter primary care medicine, obtain public health degrees, and practice medicine among the poor and ethnic minorities. In addition, medical students who have completed an international clinical rotation often report a greater ability to recognize disease presentations, more comprehensive physical exam skills with less reliance on expensive imaging, and greater cultural sensitivity. American medical students have become increasingly more interested and active in global health, but medical schools have been slow to respond. The authors review the evidence supporting the benefits of promoting more global health teaching and opportunities among medical students. Finally, the authors suggest several steps that medical schools can take to meet the growing global health interest of medical students, which will make them better physicians and strengthen our medical system.

Treating opportunistic infections among HIV-infected adults and adolescents: recommendations from CDC, the National Institutes of Health, and the HIV Medicine Association/Infectious Diseases Society of America.

The National Institutes of Health, the HIV Medicine Association of the Infectious Diseases Society of America, and CDC have developed guidelines for treatment of opportunistic infections (OIs) among adults and adolescents infected with human immunodeficiency virus (HIV). These guidelines are intended for clinicians and other health-care providers who care for HIV-infected adults and adolescents, including pregnant women; they complement companion guidelines for treatment of OIs among HIV-infected children and previously published guidelines for prevention of OIs in these populations. They include evidence-based guidelines for treatment of 28 OIs caused by protozoa, bacteria, fungi, and viruses, including certain OIs endemic in other parts of the world but that might be observed in patients in the United States. Each OI section includes information on epidemiology, clinical manifestations, diagnosis, treatment recommendations, monitoring and adverse events, management of treatment failure, prevention of recurrence, and special considerations in pregnancy. Tables address drugs and doses, drug toxicities, drug interactions, adjustment of drug doses in persons with reduced renal function, and data about use of drugs in pregnant women.

Effect of text messaging to deter early resumption of sexual activity after male circumcision for HIV prevention: a randomized controlled trial.

BACKGROUND: Resumption of sex before complete wound healing after male circumcision may increase risk of postoperative surgical complications, and HIV acquisition and transmission. We aimed to determine the effect of text messaging to deter resumption of sex before 42 days postcircumcision. METHODS: We conducted a randomized trial where men older than18 years who owned mobile phones and had just undergone circumcision were randomized to receive a series of text messages (n = 600) or usual care (n = 600). The primary outcome was self-reported resumption of sex before 42 days. RESULTS: Sex before 42 days was reported by 139 of 491 (28.3%) men in the intervention group and 124 of 493 (25.2%) men in the control group [relative risk = 1.13, 95% confidence interval (CI): 0.91 to 1.38, P = 0.3]. Men were more likely to resume early if they were married or had a live-in sexual partner [adjusted relative risk (aRR) 1.57, 95% CI: 1.18 to 2.08, P < 0.01]; in the month before circumcision had 1 (aRR: 1.50, 95% CI: 1.07 to 2.12, P = 0.02) or more than 1 (aRR: 1.81, 95% CI: 1.24 to 2.66, P < 0.01) sexual partner(s); had primary school or lower education (aRR: 1.62, 95% CI: 1.33 to 1.97, P< 0.001); were employed (aRR: 1.35, 95% CI: 1.05 to 1.72, P = 0.02); or were 21-30 years old (aRR: 1.58, 95% CI: 1.01 to 2.47, P = 0.05), 31-40 years old (aRR: 1.91, 95% CI: 1.18 to 3.09, P < 0.01), or older than 40 years (aRR: 1.76, 95% CI: 1.04 to 2.97, P = 0.03) compared with younger than 21 years. CONCLUSIONS: Text messaging as used in this trial did not reduce early resumption of sex after circumcision. We identified key risk factors for early resumption that need to be considered in circumcision programs.

Ten years of international collaboration in biomedical informatics and beyond: the AMAUTA program in Peru.

Well-trained people are urgently needed to tackle global health challenges through information and communication technologies. In this report, AMAUTA, a joint international collaborative training program between the Universidad Peruana Cayetano Heredia and the University of Washington, which has been training Peruvian health professionals in biomedical and health informatics since 1999, is described. Four short-term courses have been organized in Lima, offering training to more than 200 graduate-level students. Long-term training to masters or doctorate level has been undertaken by eight students at the University of Washington. A combination of short-term and long-term strategies was found to be effective for enhancing institutional research and training enterprise. The AMAUTA program promoted the development and institution of informatics research and training capacity in Peru, and has resulted in a group of trained people playing important roles at universities, non-government offices, and the Ministry of Health in Peru. At present, the hub is being extended into Latin American countries, promoting South-to-South collaborations.

Independent association of hygiene, socioeconomic status, and circumcision with reduced risk of HIV infection among Kenyan men.

Among Kenyan men recruited as sex partners of women with genital symptoms, 22 of 150 were HIV seropositive. Because male HIV infection and male hygiene were unexpectedly found to be associated with each other, we examined the relationship of 5 hygiene variables with HIV infection in the men in a principal components analysis, controlling for socioeconomic status and other potential confounders. By multivariate analyses, HIV infection in men was not only independently associated with previous illness (odds ratio [OR], 5.1; 95% confidence interval [CI], 1.4-19.1) and inversely associated with being circumcised (OR, 0.12; 95% CI, 0.02-0.91), but also independently associated with a combined measure of hygiene (OR, 0.41; 95% CI, 0.19-0.90).

Do people really know their sex partners? Concurrency, knowledge of partner behavior, and sexually transmitted infections within partnerships.

BACKGROUND AND OBJECTIVE: An individual's risk of sexually transmitted infections (STIs) has been associated empirically with the individual having concurrent sexual partners (individual's concurrency) and, theoretically, with the individual's partner having concurrent partners (partner's concurrency). GOALS: The goals of this study were to assess the relationship of STI to individual's concurrency, the partner's concurrency, and awareness of the partner's concurrency. STUDY DESIGN: We recruited 192 individuals aged 18 to 30 from sexually transmitted disease and family planning clinics in 96 partner dyads that reported first sexual contact during the previous 3 months. All individuals underwent computer interviews and testing for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Individuals' self-reports of concurrency and perceptions of partners' concurrency were compared within dyads by kappa statistic; associations of STI with individual's concurrency, partner's concurrency, and knowledge of partner's concurrency were examined using chi-squared analysis, t tests, and multivariate logistic regression. RESULTS: Only 26% of individuals whose partners had other partners were aware of this (kappa = 0.17 for agreement of perceptions vs. partners' reports of concurrency). In multivariate models, STI in individuals was independently associated with partners' concurrency (odds ratio [OR], 3.6), lack of awareness of partner's concurrency (OR, 4.5), perceiving a partner to have concurrent partners when the partner did not (OR, 4.7), living in south San Diego, and sexual contact within 1 week of acquaintance, but not with individuals' concurrency. CONCLUSION: This study demonstrates that STI is associated with partner's concurrency and with not knowing one's partner's behavior.
