Why Gout Does Not Always Hurt

Urate crystallizes as a monosodium salt in oversaturated tissue ?uids. Its crystallization depends on the concentrations of both urate and cation levels. Several other factors contribute to the decreased solubility of sodium urate and crystallization. Alteration in the extracellular matrix leading to an increase in nonaggregated proteoglycans, chondroitin sulfate, insoluble collagen ?brils, and other molecules in the affected joint may serve as nucleating agents. Furthermore, monosodium urate (MSU) crystals can undergo spontaneous dissolution depending on their physiochemical environments. Chronic cumulative urate crystal formation in tissue ?uids leads to MSU crystal deposition (tophus) in the synovium and cell surface layer of cartilage. Synovial tophi are usually walled off, but changes in the size and packing of the crystal from microtrauma or from changes in uric acid levels may loosen them from the organic matrix. This activity leads to "crystal shedding" and facilitates crystal interaction with synovial cell lining and residential in?ammatory cells, leading to an acute gouty ?are.

Overview of high uric acid leading to urate crystal deposits. Many factors can enhance or inhibit the formation of crystals, which is why high uric acid may not manifest itself as gout immediately.

Uric Acid Levels & Gout

Annual incidence of gout was less than 0.1% for men with serum uric acid levels less than 416 ?mol/L, 0.4% for men with levels of 416 to 475 ?mol/L, 0.8% for men with levels of 476 to 534 ?mol/L, 4.3% for men with levels of 535 to 594 ?mol/L, and 7.0% for men with levels greater than 595 ?mol/L, according to the Normative Aging Study (13). The solid line denotes these data points; the dotted line shows an exponential projection of the data points.

This chart emphasizes how the risk of gout rises with higher uric acid levels. The data comes from “Asymptomatic hyperuricemia. Risks and consequences in the Normative Aging Study.” report, from which, the abstract states:

To quantify the consequences of asymptomatic hyperuricemia, this study examined rates for a first episode of gouty arthritis based on 30,147 human-years of prospective observation. A cohort of 2,046 initially healthy men in the Normative Aging Study was followed for 14.9 years with serial examinations and measurement of urate levels. With prior serum urate levels of 9 mg/dl or more, the annual incidence rate of gouty arthritis was 4.9 percent, compared with 0.5 percent for urate levels of 7.0 to 8.9 mg/dl and 0.1 percent for urate levels below 7.0 mg/dl. With urate levels of 9 mg/dl or higher, cumulative incidence of gouty arthritis reached 22 percent after five years. Incidence rates were three times higher for hypertensive patients than for normotensive patients (p less than 0.01). The strongest predictors of gout in a proportional hazards model were age, body mass index, hypertension, and cholesterol level, and alcohol intake. When the serum urate level became a factor in the model, none of these variables retained independent predictive power. At the final examination, only 0.7 percent of participants had a serum creatinine level of 2.0 mg/dl or more, with no evidence of renal deterioration attributable to hyperuricemia. These data support conservative management of asymptomatic hyperuricemia.

Development Of Gout Overview

Gout is mediated by the supersaturation and crystallization of uric acid within the joints. The amount of urate in the body depends on the balance between dietary intake, synthesis, and excretion. Hyperuricemia results from the overproduction of urate (10%), from underexcretion of urate (90%), or often a combination of the two. Approximately one third of urate elimination in humans occurs in the gastrointestinal tract, with the remainder excreted in the urine.

Diagram showing that, if excretion of gout through kidneys and the gut is less than food intake and natural metabolism, then uric acid becomes too concentrated, and crystallization may lead to gout

Diet Gout Management Plan

Diet In A Gout Management Plan

Gout diet is crucial, but only as part of a gout management plan. This image illustrates clearly how top rheumatologists see that diet is important, but only in the context of a proper diagnosis followed by a proper treatment plan. The full chart, in Gout: Diagnosis and Management of Gouty Arthritis and Hyperuricemia, is clearly aimed at doctors, but you must also see gout diet as part of a gout treatment plan that monitors and manages your uric acid levels and all other aspects of gout.

Diet And Gout

Diet And Gout Table (click image for full size)

Table of dietary recommendations for gout management. Taken from Gout: Diagnosis and Management of Gouty Arthritis and Hyperuricemia, this diet and gout list shows how overall gout diet is much more important than individual food items.

I have included other principles in my Gout Diet Section, as their are other important food factors. Also, beverages, exercise, and other lifestyle issues must be considered. The best approach is to assess your current diet, then slowly adjust that diet, decreasing bad influences, and increasing good ones. That way, you are more likely to stick to gout diet improvements.

Milk For Gout Diet

Uric Acid Percent Change After Milk

A chart comparing the 10% increase in uric acid after drinking soy milk, with the 10% decrease after drinking skim milk.

Please remember that no single individual food is important. You (or your nutritionist) should check the Gout Diet Section to fully understand the part that food and drink play in the treatment of gout)

High Protein Foods

High Protein Foods: How Do They Affect Gout?

All these delicious high protein foods are often banned for gouties. But who is doing the banning? And do they know what they are talking about?

I’ve used this image in a number of gout diet articles where I’ve discussed the relationship of protein to gout.

Have a browse, and you’ll see that the low protein brigade are rarely right.
