Absolute, relative changes and P values are comparing treatment group s vs placebo group. All studies were randomized, placebo-controlled trials. HDL, ratio of total cholesterol to high-density lipoproteins, bid, twice daily; qd, once daily.

Safety and efficacy of tesamorelinin HIV-associated lipodystrophy Two randomized controlled trials were then conducted to evaluate the safety and efficacy of tesamorelin in HIV-infected patients with abdominal obesity. Patients were excluded if they were receiving estrogen, GH or related products, or had a diagnosis of pituitary disease.

Patients were randomly assigned in a ratio of 2: The studies consisted of two phases: It was followed by a week extension phase to evaluate long-term safety. In this phase, patients who received tesamorelin in the first phase were again randomized to receive either tesamorelin or placebo in a ratio of 3: The primary end point was the percentage change from baseline in VAT, defined as the number of square centimeters of visceral adipose tissue and as assessed by CT scanning using an analysis of covariance ANCOVA.

Secondary end points included the ratio of subcutaneous to visceral adipose tissue VAT: Both studies showed concordant findings in the primary endpoint: There were also concordant declines in VAT: It is however important to note the somewhat different magnitude of effect observed in both trials.

A subgroup analysis by gender presented in an FDA briefing on the drug NDA reported that the percent change from baseline in VAT was similar for females across studies but different for males with larger reductions in the first study.

Introduction Before effective anti-HIV drugs became available, the outlook for people with HIV or AIDS who developed cancer usually was not nearly as good as it was for people with similar cancers who were not infected.

Palliative therapy may be more appropriate in patients with advanced disease. Since that time, the HIV epidemic has spread to other populations, and infected people are living longer.

Nonetheless, tesamorelin improved patient and physician ratings of abdominal profile in both studies. VAT decreased by 24 cm2 in patients receiving tesamorelin compared with an increase of 2 cm2 in patients receiving placebo.

Also, all improvements in lipid parameters were statistically significant in the tesamorelin group compared with placebo: During the continuation phase of the studies, the improvement in VAT was not sustained among patients who were re-randomized to placebo after 26 weeks of therapy with tesamorelin T-P.

However, those randomized to continue tesamorelin for an additional 26 weeks T-T experienced a sustained reduction in VAT. No significant changes in glucose parameters or immunological function were observed. The rapid reversal of the tesamorelin effects on body fat and lipid levels upon discontinuation of therapy is probably explained by the reversal of IGF-1 increases.

Among patients maintained on tesamorelin for 52 weeks, the IGF-1 levels remained at the levels achieved at week 26, but they returned to baseline for patients switched to placebo at week There were no significant changes in glucose and insulin levels over 52 weeks. None of the serious adverse events were deemed to be related to the study drug.

However, an FDA briefing document on the drug NDA reported a statistically significant difference in the proportion of patients who developed diabetes mellitus in the tesamorelin group. Implications of clinical efficacy studies of tesamorelin In summary, tesamorelin has been shown to reduce VAT significantly, but this effect is transient and is reversed upon discontinuation of the medication.

The beneficial impact of tesamorelin on triglyceride levels has not been consistently shown across studies.

Two main cautionary points should then be raised concerning the use of tesamorelin in HIV-infected patients with abdominal obesity: The effect of tesamorelin on VAT is not sustained with discontinuation of therapy. Patients in the Phase III trials who were switched from tesamorelin to placebo after 26 weeks demonstrated a re-accumulation of VAT to near baseline levels.

Chronic therapy therefore appears to be necessary to maintain the reductions in VAT, with potential exposure to long-term side effects of GH and IGF-1 stimulation.

Despite the fact that GHRH administration is expected to preserve more physiologic GH secretory pulsatility and IGF-1 feedback inhibition, results from the clinical trials presented above show that patients are not free from IGF-1 related adverse events: Because waist circumference and VAT have been shown to be independent predictors of cardiovascular morbidity and mortality, 1987 the investigators have suggested that reduction in VAT by tesamorelin might also reduce cardiovascular risk.

However, this has not yet been investigated. It is not known if VAT reduction with therapies that target the GH axis is associated with any improvements in clinical endpoints such as reduction in number or severity of cardiovascular events or cardiovascular death.

Indeed, the statistically significant increase in the proportion of patients with treatment-emergent diabetes in the tesamorelin group vs placebo could adversely impact their cardiovascular risk.

The use of tesamorelin in HIV-infected patients should therefore be the result of a careful risk-to-benefit ratio analysis. One needs to make a determination whether the improvements in VAT — associated with inconsistent improvement in lipid profiles and unknown cardiovascular benefit — are worth the potential risk of chronic stimulation of the GH axis.

These risks are feared to include pituitary hyperplasia or benign pituitary adenoma in an era of increased concerns over non-AIDS malignancies. Chronic exposure to these drugs can result in differential effects on body fat. Changes in body habitus are disfiguring, stigmatizing, and can cause psychological distress and negatively affect the quality of life.Infection with the human immunodeficiency virus (HIV) results in progressive depletion of the CD4 subset T-lymphocytes and the development of opportunistic infections and certain malignancies.

The two intramural divisions of NCI, the Center for Cancer Research (CCR) and the Division of Cancer Epidemiology and Genetics (DCEG), conduct research on both HIV and HIV/AIDS-associated cancer. For example, DCEG is conducting the HIV/AIDS Cancer Match Study, which uses data previously collected by public health agencies to examine cancer risk in people with HIV.

After entering into the HAART era, more HIV-infected patients with malignancies have accepted chemotherapy which is contradicted to immunocompromised patients. Benefiting from efficient HAART and the advancement of anticancer therapy, the outcome for HIV-infected patients with cancers has been improved significantly.

HIV-infected women are at increased risk for certain malignancies and premalignant HPV-related changes.

Screening recommendations and treatment of HIV-related cancers in women are reviewed. Until recently, several studies have shown that abdominal operations for HIV-infected patients have higher postoperative septic complications and mortality rate[].

However, to our knowledge, no detailed reports focusing on HIV-infected patients with malignancies undergoing abdominal operations have been published.

HIV-infected patients on highly active antiretroviral therapy (HAART) develop a complex of body composition changes known, including peripheral fat loss (lipoatrophy) and central fat accumulation (lipohypertrophy).

These changes may cause significant patient distress, which could in turn interfere.
