How Does Hyperuricemia Cause Kidney Failure
Do you know that kidney failure is the worst complication of hyperuricemia? After you read this article, you will be enlightened about kidney failure in a more detail information. This article will explain how Hyperuricemia causes kidney failure. And in addition, you will know what makes the kidney failure the worst of all the complications of hyperuricemia.
Although gout is also a painful torture, gout is not the worst complications of hyperuricemia. Gout can only be worse than kidney failure when the patient has both gout and kidney failure.
How Do I Know If I Have Gout
Gout can only be diagnosed during a flare. Your doctor can diagnose with an x-ray and lab tests. They will look for uric acid crystals in the inflamed joint.
Only a doctor can diagnose you with gout. You can look for a rheumatologist, which is a doctor that specializes in musculoskeletal disease and systemic autoimmune conditions.
Treating Gout And Tophi With Surgery
Uric-acid-lowering drugs can reduce the size of tophi over time. Some people may opt to have tophi surgically removed for cosmetic reasons.
Your doctor may recommend surgical removal for tophi if they are causing mechanical problems with your joints.
Surgery for gout can help to reduce joint problems caused by tophi, including difficulty walking or nerve damage from tophi pressing against a nerve.
Tophi can erode through the skin, causing chronic ulcers that can become infected. These may require surgical removal.
Tophi removal is a relatively simple procedure. Your doctor will make a small incision on the skin over the tophi, remove the mass, and then suture the wound.
People with severe joint damage or bone loss around the joint may need additional joint replacement surgery.

For some people, gout can be chronic, which means multiple, severe gout attacks several times a year.
Chronic gout, sometimes called gouty arthritis, can lead to a number of serious complications if left untreated.
Complications of gout include:
- Loss of mobility or range of motion
- Bone loss
- Chronic kidney disease
Effects Of Uric Acid On Innate Immune Cells
The typical example of the proinflammatory effect of uric acid is gout, an inflammatory arthritis caused by the intra-articular deposition of MSU crystals. The inflammatory nature of gout is clearly demonstrated by an increased level of white blood cells in the synovial fluid from patients who experience an acute attack of gout. How MSU crystals actually induce the inflammatory reaction was unknown until 2006, when Martinon et al. discovered that uric acid crystals cause gout by activating the NOD-, LRR-, and pyrin domain-containing 3 inflammasome. NLRP3 acts as a cytosolic sensor in innate immune cells. Upon its activation by specific danger stimuli, NLRP3 begins to oligomerize and recruit apoptosis-associated speck-like protein containing a CARD and procaspase-1 . The assembly of NLRP3 , ASC , and procaspase-1 forms the NLRP3 inflammasome. In this cytoplasmic multiprotein complex, procaspase-1 is cleaved into its active form, caspase-1, which then converts pro-IL-1 and pro-IL-18 into the biologically active cytokines IL-1 and IL-18, respectively . An vitro study has shown that MSU crystals activate intracellular NLRP3 inflammasomes in cultured monocytes and mouse peritoneal macrophages and then induce IL-1 and IL-18 production .

Pathogenesis Of Acute Gouty Arthritis
Deposition of UA crystals in the joint cavity is the triggering cause of gout. These crystals initiate the inflammatory process by being engulfed by synovial phagocytic cells leading to release of lysosomal enzymes and production of inflammatory chemokines. Another mechanism is that UA crystals change the stability of cell membrane of phagocytic cells by direct crosslinkage with membrane lipids and glycoproteins. This involves the triggering of G protein, phospholipase A2, C and D, tyrosine kinase and other kinases such as mitogen-activated kinases and c-Jun N-terminal kinase. This interaction leads to increased IL-8 in phagocytes resulting in activation of neutrophils , .
The pathogenesis of gouty arthritis involves initial activation of monocytes and mast cells followed by neutrophils. Before the first attack of gout and in the inter-critical period, macrophages engulf UA crystals. Well-differentiated macrophages have the capability to contain these crystals without inducing an inflammatory response. While less-differentiated monocytes produce abundant amounts of TNF, IL-1, IL-6 and IL-8 along with endothelial activation following phagocytosis of urate crystals. Also, mast cells are key players in inducing the acute gouty attack by producing histamine and IL-1. This results in increasing vascular permeability and vasodilatation. Interestingly, it is thought that may even end the inflammatory phase by engulfing the crystals and the inflammatory debris , .
Gout Symptoms And Complications
Gout is not gout until symptoms occur. When they do, they usually come on suddenly and, at least initially, affect a single joint. Within hours, that joint becomes red, swollen, hot, and painful they’re called gout attacks for a reason. It’s easy to mistake a gout attack for a localized infection of a joint. The metatarsophalangeal joint at the base of the big toe is often the site of the first attack, but the knees, ankles, and joints between the many small bones that form the foot are also common sites. People who already have osteoarthritis the most common form of arthritis often experience their gout attacks in the joints of the finger

Why Do Gout Attacks Happen More At Night
Gout attacks happen more at night and in the early morning rather than during the day. You may have an attack start during your sleep. The reasons this happens are not entirely known, but some of the leading ideas are dehydration, lower body temperature, and changes in hormone levels during sleep. Talk to your doctor about ways to prevent gout attacks during your sleep.
The Consequences Of Suffering From Kidney Failure
Do you know that kidney failure can cause death? Although gout can also be severe, it cannot kill the patient directly. But, it can cause serious health conditions that can kill the patient eventually.
Kidney failure confuses people. They say that kidney failure is a complication of gout, but it is a hyperuricemia complication. And they also say that gout is also hyperuricemia complication. It can really confuse people, right?
But, the fact is uric acid is the cause of these. These entwine conditions are assured to show symptoms one condition after the other one. Too high level of uric acid causes hyperuricemia, and hyperuricemia causes kidney failure and gout. Although gout cannot kill the patient, kidney failure can kill. That is why it is important to reverse the symptoms of hyperuricemia.
Too high level of uric acid can add to the symptoms of kidney failure. High level of uric acid is harmful to the kidney. It adds to the toxins that the kidney has to discharge.
There are many risk factors that are related to uric acid. But before that, we also need to understand the functions and mechanisms of the kidney.
Nephrons are the units of the kidneys that are responsible for filtering wastes. And the process of filtering happens inside the glomerulus, on the wall layers of the glomerulus.

How Common Are Gout
Gout affects nearly 10 million U.S. adults, according to a 2019 study in the journal Arthritis & Rheumatology. Kidney stones affect roughly 10 percent of U.S. adults, according to a 2018 review published in the Journal of Clinical Urology. But there is limited research on the prevalence of having both gout and kidney stones.
Dr. Toprover cites two main studies that examine the occurrence of the two conditions. The first, a 2015 review of 17 studies that found, overall, 14 percent of patients with gout had kidney stones. A 2019 observational study in Brazil found 35 percent of gout patients had kidney stones.
A 2017 study in Sweden found that the risk of nephrolithiasis was 60 percent higher in people with gout compared to those without. The researchers also found that being male, obese, and having diabetes increased the risk of those with gout developing kidney stones.
How Can You Overcome It
When the kidney is damaged, the patient has to rely on a dialysis machine. When the kidney can no longer function properly, Dialysis can artificially remove the waste from the blood. But, it will be very expensive. The patient can also undergo a kidney transplant. It will involve a surgery to replace your damaged kidney with a healthy kidney. And the patient has to take medications for the rest of his life.
That is why, as soon as possible, we have to take care of our health. We should also do what we can to reverse the symptoms of hyperuricemia before it gets worse. Do not wait for the symptoms to get worse before you take action.

If you are otherwise healthy, you should not stop taking your gout medications. And, like always, treat gout flares quickly, says Dr. Fields. Its like a book of matches if the whole book is lit, its hard to put it out. One match is easier to put out, so start treatment early.
Kidney Disease And Gout
People who have kidney disease are generally more susceptible to abnormally high amounts of uric acid in their blood, or hyperuricemia. Because their kidneys are unable to remove adequate amounts of uric acid from the body, gout occurs. If a person has had a kidney transplant, they become more susceptible to gout as a result of medications taken to aid the assimilation of the kidney into the body. These medications tend to increase the amount of uric acid in the individual’s body and the person may develop gout, tophi and persistent arthritis as a result of medication.

How Can Uric Acid Stones Be Prevented
You can help to prevent uric acid stones if you do the following:
- Drink at least three quarts of fluids daily water is best.
- Limit the amount of alcohol you drink.
- Achieve or maintain a healthy weight.
- Avoid crash dieting, which increases uric acid levels in the blood.
- Follow the Dietary Approaches to Stop Hypertension diet, which has been shown to reduce not only high blood pressure but also the risk of kidney stones.
Many patients may also need to take prescribed medications to prevent uric acid stones and keep them from coming back.

Who Should Diagnose And Treat Gout
The disease should be diagnosed and treated by a doctor or a team of doctors who specialize in care of gout patients. This is important because the signs and symptoms of gout are not specific and can look like signs and symptoms of other inflammatory diseases. Doctors who specialize in gout and other forms of arthritis are called rheumatologists. To find a provider near you, visit the database of rheumatologistsexternal icon on the American College of Rheumatology website. Once a rheumatologist has diagnosed and effectively treated your gout, a primary care provider can usually track your condition and help you manage your gout.

Is There A Relationship Between Gout And Kidney Stones
Uric acid stones are the second-most commonly formed kidney stones, behind calcium oxalate stones. As gout is also related to excessive uric acid in the body, the connection between both of these health issues is uric acid.
One study early in 2020 showed that in researching the prevalence of stones, 13.9% were caused by high uric acid levels. In the study, the ages of those with these stones were in their 30s up to the 60s.
Another study found that in a group of gout patients, 31% had developed kidney stones. Of the kidney stone developers, more than half of them had no history of kidney stone formation before their gout diagnosis.
A condition known as uric acid nephrolithiasis is when there is a low urine pH, low urine volume, that lead to uric acid stone formation.
Patient Selection And Characteristics
A total of 220,763 patients were initially identified from the health plan database, based on the presence of at least 1 medical claim for gout or 1 fill for gout medication between 1/1/02 and 12/31/05 . After application of age criteria, continuous enrollment criteria, and criteria requiring no cancer during baseline, 41,290 patients remained. Of these 41,290 patients, 19,828 met the study criteria for having gout. The sample was further reduced to only include patients with available serum creatinine results during the first 12 months of follow-up. After application of all inclusion and exclusion criteria, a final sample of 3,929 patients was selected for the study.

Most Common Kidney Problems
Acute gout attacks can be extremely painful, but the symptoms are often brought under control with medication, and theres a chance you wont experience another painful episode. However, when uric acid is allowed to build up in the blood over a long period of time, gout can lead to widespread problems in multiple systems. In some cases, the damage can be permanent.
Your kidneys are responsible for removing excess uric acid from the bloodstream, so when theres too much of it to dispose of, the kidneys can be overworked. In turn, you could develop:
Kidney Stones
When uric acid crystals lodge in the joints, you get a gout attack when they settle in the kidneys or urinary tract, you get kidney stones. These small stones are hard and insoluble, and the larger they are, the more pain they will cause.
The sharp edges of kidney stones can physically scar your kidneys, or obstruct pathways and interfere with waste removal. If they go untreated for long enough, infections can develop.
Kidney Disease
Damaged kidneys are at a much higher risk for kidney disease, which is diagnosed when kidney function is severely reduced for three months or more. In many cases, symptoms of kidney disease are vague or mild, especially in the early stages.
Instead of relying on physical symptoms, your doctor can conduct an estimated glomerular filtration rate test or a urine albumin test to get a better idea of your kidney function.

Are Your Kidney Stones Due To Gout Or Something Else
According to the American Urological Foundation, kidney stones can cause severe and sharp pain, specifically in the back and abdomen, as well as while urinating. They could also cause nausea, vomiting, blood in urine, or frequent urination.
These symptoms could point to any of the four types of kidney stones, which are classified based on what they are made of:

What Causes Tophaceous Gout And Tophi Deposits
People with this kind of gout get tophi. Tophi are hard uric acid deposits that form beneath the skin. Tophi look like chalky lumps under the skin.
They can be found on or near the elbow, finger, or toe joints. Tophi can also appear on the outer part of the ear.
Tophi can destroy bone and cartilage, leading to joint damage and deformity, according to the Cochrane Database of Systematic Reviews.
They can swell during a gout attack and pop through the skin and become infected.
With treatment, tophi can dissolve and eventually disappear.
Not everyone with gout develops tophi.
Certain groups share a higher risk for tophaceous gout, according to the physician-run website UpToDate. Those at risk for tophaceous gout include:
- Organ transplant recipients who receive certain types of medication to prevent transplant rejection
- People who cant take uric-acid-lowering medicines
- Postmenopausal women, especially those taking a diuretic.
