Lipodystrophy: some comments from Nelson Vergel
Nelson Vergel, long-time AIDS treatment activist and community expert on lipodystrophy, recently posted a good set of guides to understanding this topic:
–D4T and AZT linked to lipoatrophy; some protease inhibitors linked to insulin resistance, which can be related to higher triglycerides and fat cell size in some patients
–exercise helpful for maintaining lean body mass; anabolic steroids for help in regaining normal weight
–supplements like omega-3/fish oil and niacin to help statins and fibrates to lower bad cholesterol (LDL), triglycerides and increasing good cholesterol (HDL)
Also included in the post are reviews of some regimen-switching strategies to counter lipodystrophy.
“Unfortunately,” Nelson concludes, more research is still needed on “lower glycemic index diets, good comparison data of what happens to visceral fat when different protease inhibitors or non-nucleosides are used with Truvada in naives with low and higher CD4 at baseline, diet/exercise combinations, and other supplements like carnitine and others.”

Curcumin and diabetes-related kidney disease
Curcumin, a component of the Indian spice turmeric, is known to have antioxidant, anti-inflammatory and antiviral properties, and has recently been studied for its potential effectiveness against a wide range of diseases, including cancer, diabetes, arthritis, and Alzheimer’s disease.
Here’s just one study from the National Center for Complementary and Alternative Medicine’s list of newly fund research: “Efficacy/mechanism of curcumin in diabetic nephropathy.” This study seeks to understand mechanisms and efficacy of curcumin against diabetes-related kidney disease.

Vitamin C
Vitamin C in a sustained release form (to maintain useful levels over time) is highly recommended for daily use by NYBC. Here’s an excerpt from the website description:
Vitamin C Overview: Vitamin C is another critical nutrient, an antioxidant and highly efficient free radical scavenger, antiviral, antibacterial and antifungal which should be in any HIV protocol. Vitamin C is responsible for the reactivation of key antioxidants, particularly vitamin E, beta-carotene, and glutathione, after they have been oxidized by donating electrons to neutralize a free radical (known as the redox process). Vitamin C and certain sulfur amino acids are the only water-soluble nutrients which can be taken in sufficiently large, yet safe, quantities to effectively conduct this redox process.

“Prevention of Diabetes with Nutritional Supplements”
“Prevention of Diabetes with Nutritional Supplements” is the title of a research project funded in 2007 by the National Center for Complementary and Alternative Medicine (an NIH Center). The researchers at University of California – Davis are investigating alpha lipoic acid and a combination of alpha lipoic acid and the omega-3 fatty acid EPA as means to prevent or delay onset of Type 2 diabetes. The researchers are hypothesizing that the combination of ALA and the omega-3 fatty acid (also known as eicosapentaenoic acid, a component of fish oil supplements) may have effect against insulin resistance associated with adult-onset diabetes, and against impairment of pancreatic function.

Maintaining bone health – recommendations for Calcium and Vitamin D3 supplementation
Calcium and Vitamin D are both important for keeping bones healthy. Calcium is needed by the body every day, and if not enough is taken in, then calcium is lost from the bones. Meanwhile, in order to absorb calcium effectively, the body needs Vitamin D3. So these two nutrients are both necessary, on a very regular basis, for the long-term maintenance of bone health and the prevention of such conditions as osteopenia and osteoporosis.
Recently, there has also been a lot of research and discussion about the optimum intake of Vitamin D3 to maintain bone health. Many investigators now believe that a minimum of 700 to 800 IU of vitamin D3 per day is needed by adults. This is approximately double the daily intake of 400mg that was commonly recommended in the past.
Other lines of recent research have pointed to supplementation with calcium and Vitamin D3 as having benefits in reducing risk of cancer in some populations; and there is also much study now being devoted to Vitamin D3’s role in the health of the immune system. So the old “sunshine vitamin” is definitely one to watch!

Hepatitis C and HIV Co-infection: A Treatment Update from CATIE
The Canadian AIDS Treatment Information Exchange (CATIE) has devoted the June/July Issue 2008 of its Treatment Update to a review of recent research on Hepatitis C and HIV. Here are some of the main points:
1. Although commonly viewed as simply a liver disease, Hepatitis C in recent research is strongly linked to diabetes, pre-diabetes and insulin resistance. In fact, about one-third of people with Hep C show insulin resistance, a complication that reduces chances of recovery and may lead to additional problems. Thus, researchers “need to find ways to reverse IR [insulin resistance]. Such methods could include clinical trials of diet, exercise programs and insulin-sensitizing drugs or supplements such as chromium.”
2. The HIV medication ddI (didanosine, Videx or Videx EC) has been associated with liver disease in some cases. Researchers have speculated that ddI decreases levels of a protective compound called glutathione (GSH), which is used in the body to make enzymes that help detoxification. NAC, or N-acetyl-cysteine, has been shown to raise GSH levels in people with HIV, and so could be helpful in countering ddI-related liver problems. (However, no clinical trials have yet been conducted to assess NAC’s impact on the liver health of people with HIV taking ddI.)

Melatonin for high blood pressure (hypertension)
There’s a long history of studies of melatonin as a sleep aid, but more recently there has also been research with human participants suggesting that this hormone may be helpful not only in regulating sleep patterns but also in lowering blood pressure.
High blood pressure or hypertension poses a risk over the long term to the cardiovascular system, and it’s now widely agreed that controlling hypertension is one of the most significant steps people can take to prevent adverse events such as heart attack.
Using melatonin as an aid to lowering blood pressure presents some advantages over prescription medications used for this purpose, since the prescription drugs often have unwanted side effects such as decreased sexual performance and fatigue.
Note that when low-dose melatonin was used at bedtime to reduce blood pressure in a Harvard Univ. study, the decrease in blood pressure was not dramatic, but still significant enough to help those with borderline blood pressure problems.
Of course anyone interested in the potential of melatonin supplementation for control of blood pressure should consult with a doctor before using.

The Leading Cause of Acute Liver Disease in the USA?
It’s not alcohol or hepatitis, but rather acetaminophen poisoning. Acetaminophen, the active ingredient in Tylenol and many other over the counter drugs, can damage the liver when taken in excess. And it’s easy to over-dose on acetaminophen, if you don’t carefully read labels of all the products you’re taking.
But here’s the good news (and it’s a shame it’s not more widely known in the USA): there is a readily available, simple antidote to acetaminophen poisoning. It’s actually added to acetaminophen in many European formulations of the drug, as a preventive measure. It’s
called N-acetyl-cysteine, or NAC. Using NAC along with acetaminophen-containing drugs could prevent many cases of liver disease or liver damage in the USA every year.

CATIE Treatment Update: Chromium supplements for metabolic problems in people with HIV
The Canadian AIDS Treatment Information Exchange (CATIE) website has posted news about a new study of chromium supplements for metabolic abnormalities in people with HIV. Here’s the introduction:
Can chromium supplementation help body shape?
A research team at Toronto General Hospital found a statistical link between low chromium levels in the blood and HIV infection, particularly in HAART users. The Toronto team also noted that some of the symptoms of chromium deficiency are similar to the metabolic problems—higher-than-normal levels of blood sugar and insulin and the weakened effects of insulin—in some HIV positive people. So the team later conducted a double-blind study with a modest dose of chromium vs. placebo in people with HIV infection. Their findings suggest that chromium supplementation may confer some benefit(s) in people with HIV/AIDS (PHAs) in the short-term.
Read the entire article on the CATIE website.
This April/May 2008 post from CATIE follows after news of several other studies regarding chromium supplementation and metabolic complications in people with HIV. In February 2008, for example, the 15th Conference on Retroviruses and Opportunistic Infections in Boston included a report
entitled “Chromium supplementation decreases insulin resistance and trunk fat.”

Creatine supplementation to improve cognitive function (memory, reaction time), mood, balance, and cerebral oxygenation
We were interested to see that the National Center for Complementary and Alternative Medicine (one of the research Centers at the federal government’s National Institutes of Health) lists a couple of new studies it is funding as of 2007 on the topic of creatine and cognitive function (“brain health”).
The dietary supplement creatine has long been studied as a means to increase muscle mass, strength and endurance, but this new line of research suggests that it may also have a beneficial effect on brain function.
The two NCCAM/NIH studies are “Central Adaptations to Creatine Supplementation in Older Men and Women” (which looks especially at how creatine might improve cognitive function, mood, and memory in older adults); and “Metabolic Neuroprotection: Creatine Supplementation in the Human Brain” (which will study the possibility that creatine supplementation can prevent the kind of progressive metabolic dysfunction that impairs brain function).
For more information on this supplement, see the NYBC entry on CREATINE, which includes dosage recommendations and information on how best to use.
