Dolan Looby SE, Collins M, Lee H, Grinspoon S. Effects of long-term testosterone administration in HIV-infected women: a randomized, placebo-controlled trial. AIDS. 2009 Mar 12. [Epub ahead of print]

Androgen deficiency is common in HIV-infected women. Dolan Looby and colleagues investigated the long-term effects of transdermal testosterone on body composition, bone mineral density, quality of life, and safety. Twenty-five HIV-infected women with free testosterone below the median (</=3 pg/ml) of the female normal range were randomized to receive transdermal testosterone (300 mug twice weekly) or identical placebo over 18 months. Women demonstrated low androgen levels (1.3 +/- 0.1 pg/ml) with relatively low weight (22.8 +/- 0.6 kg/m) and low bone mineral density (-0.61 +/- 0.17 SD hip T score) at baseline. No statistically significant differences were seen between the groups at baseline. The discontinuation rate was 16% and did not differ between treatment groups (P = 0.24). Free testosterone by equilibrium dialysis increased over 18 months (7.9 +/- 1.8 vs. 0.3 +/- 0.4 pg/ml; P = 0.002, testosterone vs. placebo). Testosterone was well tolerated and did not affect lipids, liver, or safety indices. Lean mass (1.8 +/- 0.5 vs. 0.8 +/- 0.9 kg; P = 0.04) and BMI (1.6 +/- 0.4 vs. 0.8 +/- 0.6 kg/m; P = 0.03, testosterone vs. placebo) increased in response to testosterone, whereas fat mass remained unchanged. Testosterone increased bone mineral density at the hip (0.01 +/- 0.01 vs. -0.01 +/- 0.01 g/cm; P = 0.02) and trochanter (0.01 +/- 0.01 vs. -0.02 +/- 0.01 g/cm; P = 0.01, testosterone vs. placebo). Testosterone significantly improved depression indices (-6.8 +/- 2.2 vs. -1.9 +/-3.1; P = 0.02) and problems affecting sexual function (-1.8 +/- 0.8 vs. 0.5 +/-0.5; P = 0.01, testosterone vs. placebo). Long-term testosterone administration was well tolerated in HIV-infected women and resulted in significant improvements in body composition, bone mineral density, and quality of life indices. Further evaluation of the safety and efficacy of testosterone use among HIV-infected women is warranted.

Editors’ note: Androgen deficiency is highly prevalent among women living with HIV and is associated with reduced lean body mass, bone mineral density, and quality of life. Whereas treatment is routine in HIV-positive men with low testosterone levels, no treatment strategies exist for women with similar problems. This is the first long-term (18 months) randomised controlled trial in HIV-positive women of the effects of testosterone administered via a transdermal patch versus a control patch. Because it reveals very encouraging effects on bone mineral density, body composition, and quality of life without signs of virilisation, further studies of long-term treatment with testosterone for women living with HIV should proceed to see if these encouraging findings are confirmed.

In the current era of globalization and ease of air travel combined with the increased survival attained since the advent of potent antiretroviral therapy, HIV-infected individuals are travelling to remote and resource-limited areas of the world. Travel-related health risks in a patient with HIV depend on the patient’s immune status, destination, travel itinerary, and type of travel. HIV-infected patients with a CD4+ count of 200 cells/mm3 or lower, particularly those who are treatment-naive and newly diagnosed, are at increased risk of complications when travelling to resource-poor settings. These increased risks include those of acquiring gastrointestinal, respiratory, and endemic tropical infectious diseases. Individuals with a CD4+ count higher than 200 cells/mm3 (whether receiving antiretroviral treatment or not) are considered to have limited immune deficiency for the purpose of travel-related recommendations; in general, they may safely receive most recommended and required vaccines. Pretravel consultation before departure is crucial to address strategies to protect against vaccine-preventable diseases (routine, recommended, and required vaccinations); vector-borne diseases, particularly malaria; gastrointestinal infections; and sexually transmitted diseases. HIV-infected travellers who are ill, particularly those with fever, should undergo an immediate medical evaluation to rule out the possibility of a life-threatening infectious disease such as malaria.

Editors’ note: This excellent review should be required reading for all UN staff living with HIV who travel internationally or who live in resource-constrained settings. It compiles current knowledge on the use of live attenuated and inactivated vaccines by CD4+ count and provides practical advice. This includes delaying travel until 3 months after starting antiretroviral treatment to avoid immune reconstitution syndromes during travel, keeping medication with its official documentation in hand luggage with a back-up supply in checked luggage, hand hygiene with water and soap or alcohol-based solutions, knowing about potential protease inhibitor drug interactions with malaria treatment, careful attention to water and food safety to avoid enteric infections, adherence to safer sex strategies, and the importance of prompt evaluation of fever while travelling or on return .
