Native Hawaiians have higher risk for gout, UH study finds

May 31, 2022, 12:30 PM HST Maui News

An analysis of nearly two decades of data of 92,000 people revealed Native Hawaiians had more than twice the risk of Whites participants of developing gout as older adults.

The new study by University of Mānoa researchers — and one of the largest multiethnic gout studies to date — was published in The Journal of Rheumatology.

Gout, a common and painful form of arthritis, is becoming more prevalent in the United States. But the differences in risk between populations remains largely understudied, especially for Native Hawaiians. This study helped shed some light on these differences. It also revealed black participants had the second highest risk, followed by Japanese participants.

Uric Acid & Gout News: Hereditary Fructose Intolerance

Hereditary fructose intolerance is a disorder in which a person lacks the protein needed to break down fructose. Fructose is a fruit sugar that naturally occurs in the body. Man-made fructose is used as a sweetener in many foods, including baby food and drinks.

Causes

This condition occurs when the body is missing an enzyme called aldolase B. This substance is needed to break down fructose.

If a person without this substance eats fructose or sucrose (cane or beet sugar, table sugar), complicated chemical changes occur in the body. The body cannot change its stored form of sugar (glycogen) into glucose. As a result, blood sugar falls and dangerous substances build up in the liver.

Hereditary fructose intolerance is inherited, which means it can be passed down through families. If both parents carry a nonworking copy of the aldolase B gene, each of their children has a 25% (1 in 4) chance of being affected.

Gout: The Other Gene That Affects Urate Levels and Gout Development

The ABCG2 gene belongs to a group of genes called the ATP-binding cassette family; genes in this family provide instructions for making proteins that transport molecules across cell membranes. In the intestines, the ABCG2 protein helps release (secrete) a substance called urate into the urine. Urate is a byproduct of certain normal biochemical reactions in the body. In the bloodstream it acts as an antioxidant, protecting cells from the damaging effects of unstable molecules called free radicals. Urate levels are regulated by the kidneys and, to a lesser extent, by the intestines.

The ABCG2 protein also transports certain drugs out of cells. For example, this protein clears some chemotherapy drugs from organs and tissues. Transport of these drugs allows them to have their intended effects and be eliminated from the body.

Gout: Genes that Affect Urate Levels and Gout Development

The SLC2A9 gene provides instructions for making a protein called glucose transporter 9 (GLUT9). This protein is found mainly in the kidneys, specifically in structures called proximal tubules. These structures help to reabsorb needed nutrients, water, and other materials into the blood and excrete unneeded substances into the urine. Within the proximal tubules, the GLUT9 protein helps reabsorb or excrete a substance called urate. Urate is a byproduct of certain normal biochemical reactions in the body. In the bloodstream it acts as an antioxidant, protecting cells from the damaging effects of unstable molecules called free radicals. When more urate is needed in the body, the GLUT9 protein helps reabsorb it into the bloodstream. Most urate that is filtered through the kidneys is reabsorbed into the bloodstream; about 10 percent is released into urine.

The GLUT9 protein also plays a role in reabsorbing and excreting the simple sugar glucose.

Gout: Genetics or Lifestyle Driven?

Genetic and genetic mutations can certainly play a role in disease, however, poor nutrition and a sedentary lifestyle can greatly increase the risk. Gout is a common condition, but it occurs more frequently in some populations than others. For example, gout occurs in 1 percent of people with Asian ancestry, 3 to 4 percent of people with European ancestry, and 6 to 8 percent of Indigenous (native) Taiwanese peoples and Māori from New Zealand.

In about 15 percent of people with gout, urate accumulates in the kidneys
and forms kidney stones . As the condition worsens, urate crystals can also be deposited under the skin or in other soft tissue, forming a nodule called a tophus (plural: tophi). These tophi often form in the hands, elbows, or feet. Tophi do not typically cause pain, but they can become inflamed, infected, or ooze fluid. Depending on their location, tophi can interfere with movements such as walking or gripping objects.

Does Gout Increase The Cardiovascular Disease Risk Factor?

Cardiovascular Disease and Gout

The prevalence of cardiovascular disease continues to rise and is among the leading cause of mortality in the world. Inflammatory conditions such as Rheumatoid Arthritis and Gout are often associated with a higher risk and earlier onset of this disease. Research links gout to an increased risk of several types of cardiovascular disease, including heart attack, heart failure, and atrial fibrillation, or an irregular heartbeat. Epidemiological, experimental, and clinical data show that patients with hyperuricemia SUA are at increased risk of cardiac, renal, and vascular damage and CV events.

Is it OK to walk with gout?

Medical News Today: It is safe for people to walk with gout. In fact, doing joint friendly activities such as walking can help improve gout-related pain.

Gout is a form of arthritis that usually affects the big toe joint, but it can also affect the lesser toes, ankles, and knees. It normally affects one joint at a time.

People with gout may find it difficult to carry out physical activity, or they may be worried that physical activity will make their gout worse.

This article will examine whether or not it is safe to walk with gout. It will also cover how to manage, treat, and prevent this condition.

Gout ‘more than doubles’ risk of kidney failure

Largest ever study on subject uses data from more than 620,000 patients in UK health system

Date: August 28, 2019

Summary: Patients with gout are at increased risk of chronic kidney disease and kidney failure, according to new research.

Patients with gout are at increased risk of chronic kidney disease and kidney failure, according to new University of Limerick (UL), Ireland led research.

In one of the largest and most detailed studies ever conducted, patients recruited in general practice with a diagnosis of gout were more than twice as likely to develop kidney failure than those without, according to the study led by researchers at University of Limerick’s (UL) Graduate Entry Medical School (GEMS).

Wearable sweat sensor detects gout-causing compounds

There are numerous things to dislike about going to the doctor: Paying a copay, sitting in the waiting room, out-of-date magazines, sick people coughing without covering their mouths. For many, though, the worst thing about a doctor’s visit is getting stuck with a needle. Blood tests are a tried-and-true way of evaluating what is going on with your body, but the discomfort is unavoidable. Or maybe not, say Caltech scientists.

Gout Questions and Answers

Let us better help you better understand this condition – despite the tons of misinformation that circulates on the internet.

Why are blood test results misleading when it comes to a Gout diagnosis?

Blood tests can reveal the concentration of uric acid in your system. However, while you are under an attack your blood could potentially read quite normal. Over 60% of patients presenting with acute gouty arthritis symptoms have uric acid levels of <8mg/dl. Measuring serum uric acid levels while under an attack may not be too helpful in a diagnostic sense. Why? The crystals relentlessly jabbing at your joints are NOT in a soluble form at that time.
