Dna moczanowa
Etiologia i przyczyny
Dna moczanowa (arthritis urica) jest przewlekłą chorobą zapalną stawów, wynikającą z odkładania się kryształów moczanu sodu (MSU) w tkankach, spowodowaną hiperurykemią, definiowaną jako stężenie kwasu moczowego we krwi przekraczające 6,8 mg/dl (około 405 µmol/l). Etiologia dny moczanowej jest złożona i obejmuje przede wszystkim upośledzone wydalanie kwasu moczowego przez nerki (90% przypadków) oraz nadmierną produkcję kwasu moczowego (10%). Czynniki genetyczne, zwłaszcza mutacje w genach SLC2A9 i ABCG2, mają istotny wpływ na metabolizm i wydalanie kwasu moczowego, co potwierdza wysoka dziedziczność (około 73%). Dodatkowo, dieta bogata w puryny (podroby, czerwone mięso, owoce morza), nadmierne spożycie alkoholu i fruktozy, a także współistniejące choroby takie jak otyłość, zespół metaboliczny, nadciśnienie tętnicze i przewlekła choroba nerek, znacząco zwiększają ryzyko rozwoju dny moczanowej. Leki takie jak diuretyki, niskodawkowa aspiryna czy immunosupresanty również mogą podnosić stężenie kwasu moczowego.
Etiologia dny moczanowej
Dna moczanowa (łac. arthritis urica) jest przewlekłą chorobą zapalną stawów, spowodowaną odkładaniem się kryształów moczanu sodu (monosodium urate, MSU) w stawach i tkankach miękkich. Główną przyczyną powstawania tych kryształów jest hiperurykemia, czyli podwyższone stężenie kwasu moczowego we krwi, przekraczające 6,8 mg/dl (około 405 µmol/l), co stanowi granicę rozpuszczalności kwasu moczowego w osoczu.12
Chociaż hiperurykemia jest koniecznym warunkiem wstępnym do rozwoju dny moczanowej, sama w sobie nie jest wystarczająca – tylko u mniejszości osób z podwyższonym poziomem kwasu moczowego we krwi rozwinie się dna moczanowa. Szacuje się, że około 10% osób z hiperurykemią ostatecznie zachoruje na dnę moczanową.34
Przyczyny hiperurykemii
Kwas moczowy jest końcowym produktem metabolizmu puryn, związków występujących naturalnie w organizmie oraz w wielu pokarmach. W normalnych warunkach kwas moczowy jest rozpuszczany we krwi i wydalany głównie przez nerki z moczem. Hiperurykemia może powstać w wyniku jednego z trzech mechanizmów:567
- Zwiększona produkcja kwasu moczowego przez organizm
- Zmniejszone wydalanie kwasu moczowego przez nerki
- Połączenie obu powyższych mechanizmów
W około 90% przypadków przyczyną dny moczanowej jest upośledzone wydalanie kwasu moczowego przez nerki, a tylko w około 10% przypadków nadmierna produkcja kwasu moczowego.8910
Czynniki zmniejszające wydalanie kwasu moczowego
Zmniejszone wydalanie kwasu moczowego można przypisać różnym przyczynom:1112
- Defekty genetyczne w transporterach anionów organicznych w nerkach, prowadzące do nadmiernej reabsorpcji kwasu moczowego
- Choroby nerek i zaburzenia czynności nerek
- Przyjmowanie niektórych leków, takich jak diuretyki (leki moczopędne), niskodawkowa aspiryna, leki immunosupresyjne, cyklosporyna
- Zwiększone spożycie alkoholu, szczególnie piwa i mocnych trunków, które hamują wydalanie kwasu moczowego przez nerki
- Odwodnienie lub niedożywienie
- Zatrucie ołowiem (tzw. dna saturnińska)
- Kwasica ketonowa w przebiegu cukrzycy
Czynniki zwiększające produkcję kwasu moczowego
Nadmierna produkcja kwasu moczowego może być spowodowana przez:1415
- Zwiększoną syntezę puryn z powodu defektów enzymatycznych, np. zespół Lesha-Nyhana, zespół Kelleya-Seegmillera
- Choroby powodujące zwiększony rozpad komórek, np. choroby nowotworowe (szczególnie białaczki), niedokrwistość hemolityczna, łuszczyca
- Chemioterapię nowotworów
- Dietę bogatą w puryny (czerwone mięso, podroby, owoce morza)
- Nadmierne spożycie fruktozy (syrop glukozowo-fruktozowy) i pokarmów słodzonych
Czynniki genetyczne w etiologii dny moczanowej
Dna moczanowa ma silny komponent genetyczny, dziedziczność hiperurykemii i dny moczanowej szacuje się na około 73%. Około 40-50% pacjentów z dną moczanową ma dodatni wywiad rodzinny.1920
Badania genetyczne wykazały obecność genów związanych z transportem kwasu moczowego w nerkach i jelitach. Szczególnie ważne są geny SLC2A9 i ABCG2, które wpływają na funkcję nerek i jelit w usuwaniu kwasu moczowego.2122
Czynniki genetyczne wpływają głównie na metabolizm kwasu moczowego poprzez:23
- Modyfikację wydajności wydalania kwasu moczowego przez nerki
- Wpływ na produkcję kwasu moczowego
- Wpływ na metabolizm puryn
U niektórych grup etnicznych, szczególnie u Maorysów i osób pochodzenia polinezyjskiego, występuje genetycznie uwarunkowana mniejsza zdolność nerek do wydalania kwasu moczowego, co zwiększa ryzyko rozwoju dny moczanowej.2425
Czynniki dietetyczne i stylu życia
Dieta i styl życia odgrywają istotną rolę w rozwoju hiperurykemii i dny moczanowej, chociaż ich wpływ jest często przeceniany. Szacuje się, że czynniki dietetyczne odpowiadają za około 12% przypadków dny moczanowej.2627
Pokarmy bogate w puryny
Spożywanie produktów bogatych w puryny może prowadzić do zwiększenia stężenia kwasu moczowego we krwi:2829
- Podroby (wątroba, nerki, grasica, mózg)
- Czerwone mięso
- Owoce morza i niektóre ryby (sardynki, anchois, szprotki, łosoś, pstrąg, tuńczyk, małże, skorupiaki)
- Ekstrakty mięsne i buliony
Alkohol
Alkohol zwiększa ryzyko dny moczanowej na kilka sposobów:3334
- Hamuje wydalanie kwasu moczowego przez nerki
- Powoduje odwodnienie, co sprzyja krystalizacji kwasu moczowego
- Niektóre napoje alkoholowe, szczególnie piwo, zawierają duże ilości puryn
- Powoduje zwiększoną produkcję kwasu moczowego
Napoje i pokarmy słodzone
Spożywanie napojów słodzonych, szczególnie zawierających syrop glukozowo-fruktozowy, zwiększa ryzyko dny moczanowej. Fruktoza zwiększa produkcję kwasu moczowego w wątrobie.3839
Fruktoza jest metabolizowana w wątrobie z wytworzeniem ATP, które następnie ulega degradacji do AMP i ostatecznie do kwasu moczowego, co prowadzi do zwiększenia stężenia kwasu moczowego we krwi.4041
Choroby współistniejące i czynniki ryzyka
Dna moczanowa często występuje w połączeniu z innymi schorzeniami, które mogą wpływać na metabolizm kwasu moczowego lub zwiększać ryzyko rozwoju dny.42
Otyłość i zespół metaboliczny
Otyłość zwiększa ryzyko dny moczanowej poprzez:4344
- Zwiększoną produkcję kwasu moczowego przez komórki tłuszczowe
- Zmniejszenie wydalania kwasu moczowego przez nerki
- Zwiększenie poziomu insuliny, co podnosi stężenie kwasu moczowego
Zespół metaboliczny, charakteryzujący się otyłością brzuszną, nadciśnieniem tętniczym, insulinoopornością i zaburzeniami lipidowymi, występuje u około 75% pacjentów z dną moczanową.4546
Choroby układu krążenia i metaboliczne
Z dną moczanową często współistnieją:4748
- Nadciśnienie tętnicze – osoby z wysokim ciśnieniem krwi mają nawet dwukrotnie wyższe ryzyko rozwoju dny moczanowej
- Choroba niedokrwienna serca
- Niewydolność serca
- Cukrzyca typu 2
- Hiperlipidemia (podwyższone stężenie cholesterolu i/lub triglicerydów)
Choroby nerek
Przewlekła choroba nerek jest jednym z głównych czynników ryzyka dny moczanowej, ponieważ upośledza wydalanie kwasu moczowego. Jednocześnie dna moczanowa może przyczyniać się do uszkodzenia nerek.5253
U osób z przewlekłą chorobą nerek (PChN):54
- Jedna na 10 osób ma dnę moczanową
- Około 1 na 4 osoby z dną moczanową ma PChN
Kryształy moczanu mogą tworzyć się w nerkach podczas filtracji krwi, co może prowadzić do kamicy nerkowej i dalszego uszkodzenia nerek.55
Czynniki farmakologiczne
Niektóre leki mogą zwiększać stężenie kwasu moczowego we krwi i przyczyniać się do rozwoju dny moczanowej:5657
Leki o największym wpływie na rozwój dny moczanowej
- Diuretyki (leki moczopędne) – zmniejszają wydalanie kwasu moczowego przez nerki
- Tiazydy (np. hydrochlorotiazyd, bendroflumetiazyd)
- Diuretyki pętlowe (np. furosemid)
- Niskodawkowa aspiryna (kwas acetylosalicylowy) – blokuje wydalanie kwasu moczowego przez nerki
- Leki immunosupresyjne (np. cyklosporyna, takrolimus)
- Inhibitory konwertazy angiotensyny (ACE) i antagoniści receptora angiotensyny II (sartany)
- Beta-blokery
- Niacyna (witamina B3) w dużych dawkach
- Niektóre leki przeciwnowotworowe
- Pirazynamid (lek przeciwgruźliczy)
Inhibitory pompy protonowej (IPP) również mogą zwiększać ryzyko dny moczanowej (skorygowany iloraz szans 1,3; 95% CI 1,0-1,6).61
Czynniki wyzwalające napady dny
Napady dny moczanowej mogą być wywoływane przez różne czynniki, które powodują gwałtowne zmiany stężenia kwasu moczowego we krwi:6263
- Ostre spożycie dużej ilości alkoholu
- Przejedzenie, szczególnie pokarmami bogatymi w puryny
- Gwałtowna utrata masy ciała lub głodzenie
- Odwodnienie
- Uraz stawu lub operacja
- Choroby przebiegające z wysoką gorączką
- Stres fizyczny lub psychiczny
- Gwałtowne wprowadzenie lub zmiana dawki leków obniżających stężenie kwasu moczowego
Mechanizm powstawania napadów dny
Rozwój napadu dny moczanowej przebiega w następujący sposób:6768
- Hiperurykemia prowadzi do tworzenia się kryształów moczanu sodu
- Kryształy te przedostają się do płynu stawowego i tkanek okołostawowych
- Organizm reaguje na obecność kryształów aktywacją układu immunologicznego
- Neutrofile (białe krwinki) pochłaniają kryształy moczanu
- Prowadzi to do uwolnienia mediatorów zapalnych (cytokin)
- Mediatory te powodują wszystkie objawy zapalenia: ból, zaczerwienienie, obrzęk i podwyższenie temperatury
Ten mechanizm wyjaśnia, dlaczego napad dny moczanowej może wystąpić nagle i powodować intensywny ból oraz zapalenie stawu.6970
Epidemiologia dny moczanowej
Częstość występowania dny moczanowej na świecie wzrasta, co wiąże się ze zmianami stylu życia, zwiększoną konsumpcją pokarmów bogatych w puryny oraz starzeniem się populacji.7172
Czynniki demograficzne
- Dna moczanowa jest około 3-4 razy częstsza u mężczyzn niż u kobiet
- U kobiet najczęściej występuje po menopauzie, gdy spada poziom estrogenów, które mają działanie urykozuryczne (zwiększające wydalanie kwasu moczowego)
- Ryzyko dny moczanowej wzrasta z wiekiem, szczególnie po 30. roku życia u mężczyzn i po 50. roku życia u kobiet
- Szczyt zachorowań u mężczyzn przypada na wiek 30-50 lat
Różnice etniczne
Występują znaczące różnice w częstości występowania dny moczanowej w różnych grupach etnicznych, co wiąże się głównie z czynnikami genetycznymi:7778
- Wyższą częstość występowania dny moczanowej obserwuje się wśród:
- Maorysów i mieszkańców wysp Pacyfiku
- Afroamerykanów (prawie dwukrotnie częściej niż u osób rasy kaukaskiej)
- Różnice etniczne wynikają głównie z genetycznych wariantów wpływających na metabolizm i wydalanie kwasu moczowego
Podsumowanie etiologii dny moczanowej
Dna moczanowa jest chorobą o złożonej etiologii, wynikającą z interakcji pomiędzy czynnikami genetycznymi, środowiskowymi, dietetycznymi, współistniejącymi chorobami i przyjmowanymi lekami. Głównym czynnikiem patogenetycznym jest hiperurykemia, która prowadzi do tworzenia się i odkładania kryształów moczanu sodu w stawach i tkankach.
Najważniejsze elementy etiologii dny moczanowej to:8182
- Upośledzone wydalanie kwasu moczowego przez nerki (90% przypadków)
- Nadmierna produkcja kwasu moczowego (10% przypadków)
- Predyspozycje genetyczne wpływające na metabolizm i wydalanie kwasu moczowego
- Dieta bogata w puryny i fruktoza
- Nadmierne spożycie alkoholu
- Choroby współistniejące, szczególnie otyłość, zespół metaboliczny, nadciśnienie tętnicze i przewlekła choroba nerek
- Przyjmowanie leków zwiększających stężenie kwasu moczowego
Zrozumienie złożonej etiologii dny moczanowej jest kluczowe dla właściwego podejścia terapeutycznego, które powinno uwzględniać nie tylko leczenie objawowe napadów, ale także długoterminowe obniżanie stężenia kwasu moczowego i modyfikację czynników ryzyka.8384

- #1 Gout: Clinical manifestations and diagnosis – UpToDatehttps://www.uptodate.com/contents/clinical-manifestations-and-diagnosis-of-gout
Gout is caused by tissue deposition of monosodium urate (MSU) crystals and can cause a variety of clinical manifestations, including the following: […] Providers typically diagnose gout based on a combination of clinical features, laboratory testing (eg, serum urate, synovial fluid MSU crystals), and, in some cases, imaging. […] Biochemically, gout is typically characterized by hyperuricemia with serum or plasma urate concentrations exceeding 6.8 mg/dL (approximately 405 micromol/L); this level of urate is the approximate limit of urate solubility. […] However, urate levels may be misleadingly normal during gout flares. […] Moreover, while hyperuricemia is a necessary precondition for the development of gout in almost all cases, it is not sufficient; most hyperuricemic individuals never develop gout. […] Risk factors for hyperuricemia and gout (may not be causal) […] Causes of hyperuricemia due to increased purine biosynthesis and/or urate production […] Causes of hyperuricemia due to decreased uric acid clearance […] Provoking factors for gout flares.
- #2 Gout – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK546606/
Gout is one of the most common causes of chronic inflammatory arthritis in the United States, characterized by monosodium urate (MSU) monohydrate crystals deposition in the tissues. […] The etiology of gout is usually multifactorial, including genetic predisposition, medical comorbidities, and dietary factors. In rare cases, a single genetic defect may be responsible for causing gout, usually associated with other medical complications. Irrespective of the underlying trigger, the result involves elevated serum uric acid, which can manifest as clinical gout in certain individuals. […] Hyperuricemia is the leading cause of gout, a condition where uric acid crystals accumulate in joints, causing inflammation and pain. […] Hyperuricemia, while a significant risk factor, does not singularly account for the development of gout; only a minority of individuals with elevated uric acid levels actually develop the condition.

- #4 Gout – Wikipediahttps://en.wikipedia.org/wiki/Gout
About 10% of people with hyperuricemia develop gout at some point in their lifetimes. […] The risk, however, varies depending on the degree of hyperuricemia. […] Dietary causes account for about 12% of gout, and include a strong association with the consumption of alcohol, sugar-sweetened beverages, meat, and seafood. […] Other triggers include physical trauma and surgery. […] Gout frequently occurs in combination with other medical problems. […] Metabolic syndrome, a combination of abdominal obesity, hypertension, insulin resistance, and abnormal lipid levels, occurs in nearly 75% of cases. […] Chronic lead exposure and lead-contaminated alcohol are risk factors for gout due to the harmful effect of lead on kidney function. […] Diuretics have been associated with attacks of gout, but a low dose of hydrochlorothiazide does not seem to increase risk. […] Other medications that increase the risk include niacin, aspirin (acetylsalicylic acid), ACE inhibitors, angiotensin receptor blockers, beta blockers, ritonavir, and pyrazinamide.
- #5 Causes of Gout – Harvard Healthhttps://www.health.harvard.edu/diseases-and-conditions/causes-of-gout
Gout is a chronic form of arthritis caused by too much uric acid in the body. This excess uric acid can settle in tissues, particularly the joints. From time to time, the uric acid can form needle-shaped crystals in the joint space. The body reacts to these crystals by launching an attack that causes inflammation, redness, and pain. This is a gout attack. […] While high uric acid is necessary to cause gout, it is not sufficient on its own to cause gout. In fact, not everyone with high uric acid levels develops gout. The reasons for this are not well understood. […] There are three main causes of high levels of uric acid that can lead to gout: A diet high in foods that contain high levels of chemicals called purines can increase the risk of developing gout, but they don’t cause the disease on their own.
- #6 Causes of Gout – Harvard Healthhttps://www.health.harvard.edu/diseases-and-conditions/causes-of-gout
A high production of uric acid by the body. This can happen for unknown reasons, or as a result of inherited genetic metabolic disorders or leukemia, or during chemotherapy for cancer. […] The kidneys are not excreting enough uric acid. This can be caused by kidney disease, starvation, excessive alcohol use, or medications called diuretics. […] Uric acid is a chemical that is naturally produced by the body as it breaks down purines. […] But for some people the kidneys don’t get rid of enough uric acid. This can lead to a buildup of uric acid in the bloodstream, a condition called hyperuricemia, which can lead to gout. […] Certain factors can raise your risk of gout and increase your chances of gout attacks. While these factors can make gout more likely (largely because they lead to higher uric acid levels), they don’t cause gout.
- #7 Gout Symptoms, Causes & Diet Recommendations | NIAMShttps://www.niams.nih.gov/health-topics/gout
Gout happens when high levels of urate build up in your body over a long period of time, which can then form needle-shaped crystals in and around the joint. This leads to inflammation and arthritis of the joint. […] Gout happens when urate, a substance in your body, builds up and forms needle-shaped crystals in your joints. This leads to pain, swelling, redness, and changes in the movement and use of the affected joint. However, not everyone with high urate levels develops gout. […] Urate comes from purines, which are found in your body’s tissues and many foods. When purines break down, they become urate. Normally, urate passes out of your body in urine. However, when too much is made or too little is removed, urate builds up in your blood and needle-shaped crystals form in your joints, causing inflammation that is experienced as gout flares that cause pain and swelling.
- #8 Gout/Gouty Arthritis In Depth: Risk Factors, Treatment | HSShttps://www.hss.edu/conditions_gout-risk-factors-diagnosis-treatment.asp
Gout is clearly associated with a buildup of uric acid. Uric acid is a produced as part of the body’s metabolism of purines, which are produced as the body breaks down any of the many purine-containing substances, including nucleic acids from our diet or from the breakdown of our own cells. […] The most common cause of gout (about 90% of cases) is the inability to excrete enough uric acid in the urine. This inability may occur for a number of reasons. The most common is a genetic defect in substances referred to as organic anion transporters in the kidney, which leads to an excessive reabsorption of uric acid from the kidney and thus too much uric acid in the blood. […] About 10% of cases of gout are due to overproduction of uric acid. When uric acid is overproduced, it is high not only in the blood but in the urine, raising the risk of both gout and kidney stone.
- #9 Gout and Pseudogout: Background, Pathophysiology, Etiologyhttps://emedicine.medscape.com/article/329958-overview
Gout develops in the setting of excessive stores of uric acid in the form of monosodium urate. Uric acid is an end-stage by-product of purine metabolism. Humans remove uric acid primarily by renal excretion. When excretion is insufficient to maintain serum urate levels below the saturation level of 6.8 mg/dL, hyperuricemia may develop, and urate can crystallize and deposit in soft tissues. […] About 90% of patients with gout develop excess urate stores because of an inability to excrete sufficient amounts of uric acid in the urine (underexcretion). Most of the remaining patients either overconsume purines or produce excessive amounts of uric acid endogenously (overproduction). A few have impaired intestinal elimination of uric acid. […] Causes of secondary gout due to underexcretion of uric acid include kidney insufficiency, lead nephropathy (saturnine gout), starvation or dehydration, certain drugs, and chronic abuse of ethanol (especially beer and hard liquor). These disorders should be identified and corrected, if possible.
- #10 What is gout? Causes, symptoms, diagnosis and treatment of gout.https://www.orthogyan.com/uric-acid-gout/
An inability to adequately process and excrete uric acid accounts for an estimated 80 to 90% of gout cases. […] Drinking alcohol decreases the body’s ability to flush out uric acid. Additionally, beer is made with brewers yeast, which is high in purines. […] The risk factor increases due to the frequent consumption of foods that are high in purines like meats, seafood, some vegetables and beans. Also, foods that contain fructose lead to gout. […] Genetics plays a role, making some people’s bodies more prone to accumulating uric acid and developing the uric acid crystals that lead to gout. […] Certain medications can increase the risk of gout. Some of these medications include diuretics, aspirin, and cyclosporine. […] Gout occurs when the kidney is unable to properly flush out uric acid. […] Trigger events like injury, surgery or medical therapy can cause gout. […] The precursor of gout that is hyperuricemia has to be addressed to prevent the damage from both in the long term.
- #11 Gout: Symptoms, Treatments, and Causeshttps://resources.healthgrades.com/right-care/gout/gout
There are various causes of hyperuricemia resulting from an overproduction of uric acid. These include genetic disorders with enzyme defects, drugs such as chemotherapy, diet-related disorders such as vitamin B12 deficiency, alcohol use, and medical conditions such as blood disorders and certain cancers. […] There are also disorders and factors that are associated with decreased uric acid clearance, including underlying kidney disease, medical conditions such as endocrine disorders, and medications such as laxatives or diuretics.
- #12 What is Gout? Symptoms, Causes & Diagnosis – WWMG Bloghttp://www.wwmedgroup.com/what-is-gout-symptoms-causes-diagnosis/
Gout is a systemic, chronic disease that affects the joints and organs by depositing sodium urate crystals, said Peterson. When the body produces sodium urate at a higher level than normal, or the kidneys fail to process it quickly enough, crystals build up, deposit in the joints and organs, and cause damage. […] Although flare-ups are painful, they are usually what leads to a diagnosis. Asymptomatic cases that go undiagnosed can have serious long-term impacts. […] Even when they dont cause pain, the crystals are still inflammatory. They can still nibble away at the bone and tendons. They can still invade tissues and cause them to not function properly, said Peterson. Gout can inflame tissues in the eye, kidneys, prostate or liver, causing those organs to malfunction. […] Further, this long-term inflammation leads to increased production of cortisol, also know as the stress hormone. Cortisol is like a steroid that helps to control inflammation. But it also leads to weight gain, high blood pressure, diabetes and high cholesterol, Peterson said, and can predispose people to metabolic syndrome, which can increase a persons risk of having heart disease or a stroke.

- #13 Gout Causes and Symptoms | Ausmedhttps://www.ausmed.com/learn/articles/gout
Gout is caused by an excess of uric acid – a byproduct that is normally excreted through urine. When there is excess uric acid in the blood, either because the kidneys can not excrete it quickly enough or because too much has been produced, it forms crystals (urate) in the joints. These crystals cause painful inflammations (Harvard Health Publishing 2023; Healthdirect 2024). […] Hyperuricaemia is the term used to describe high levels of uric acid in the blood. This condition alone is not necessarily a prerequisite to gout and can be present without symptoms, suggesting that gout is instead the result of a combination of factors (Better Health Channel 2024). […] Diets high in purines can be a risk factor for gout.

Gout is a kind of arthritis caused by a buildup of uric acid crystals in the joints. Uric acid is a breakdown product of purines that are part of many foods we eat. An abnormality in handling uric acid and crystallization of these compounds in joints can cause attacks of painful arthritis, kidney stones, and blockage of the kidney filtering tubules with uric acid crystals, leading to kidney failure. […] Obesity, excessive weight gain, especially in youth, moderate to heavy alcohol intake, high blood pressure, diabetes, and abnormal kidney function are among the risk factors for developing gout. Certain drugs and diseases can also cause elevated levels of uric acid. Also, there is an increased prevalence of abnormally low thyroid hormone levels (hypothyroidism) in patients with gout. […] Alcohol is known to have diuretic effects that can contribute to dehydration and precipitate acute gout attacks. Alcohol can also affect uric acid metabolism and cause hyperuricemia. It causes gout by slowing down the excretion of uric acid from the kidneys as well as by causing dehydration, which precipitates the crystals in the joints.

Gout can happen when there is a build-up of a chemical called urate (uric acid) in your body. Urate is a normal waste product that comes from the breakdown of cells and the food and drinks you have. […] Uric acid builds up either because: your kidneys do not excrete (remove) it quickly enough or too much urate is being made in your body. […] Gout occurs when these crystals cause sudden and severe inflammation, which is triggered by your immune system.

Additional factors linked to gout and hyperuricemia include older age, male sex, obesity, a purine-rich diet, alcohol, certain medications, comorbid diseases, and genetic predisposition. […] The final step of purine metabolism is the conversion of hypoxanthine to xanthine and then uric acid by xanthine oxidase, which then transforms allantoin by uricase. […] Dietary sources that can contribute to hyperuricemia and gout include the consumption of animal food such as seafood, organs, and red meat. Additionally, beverages like alcohol, sweetened beverages, sodas, and those containing high-fructose corn syrup may also contribute to the onset of this disease. […] The heritability of hyperuricemia and gout is about 73% and about 40% to 50% of patients have a family history of gout. […] Epidemiological studies have reported a rising burden of gout, primarily attributed to lifestyle changes like increased protein consumption and a sedentary lifestyle.

Although experts do not fully understand why some people get gout and others do not, many causes and risk factors of gout are well established. […] Some foods are high in purines, which turn into uric acid that can crystalize in joints, causing gout. […] Experts estimate men are 4 to 10 times more likely to have gout than women. […] Womens risk of developing gout goes up during menopause (estrogen seems to have protective effects). […] Many people have their first episode of gout between the ages of 30 and 50, and the risk of gout continues to increase with age. […] African American men are nearly twice as likely to report having had gout as Caucasian men. […] Research suggests that certain genes that influence kidney function (SLC2A9 and ABCG2) and gut function (ABCG2) increase the risk of developing gout.
- #22 What is Gout? Causes, Symptoms, and How It’s Diagnosed – CreakyJointshttps://creakyjoints.org.au/education/gout/
Gout is caused when an excessive amount of urate builds up in your blood. Urate (also called uric acid) is a natural substance or chemical. Urate is produced by your own body as it metabolizes, or breaks down, a substance in the foods and drinks you consume called purines. […] Excessive consumption of purine-rich foods can increase your risk of getting gout, since the purines are broken down in your body to make urate. […] Genetics are a key part of how we get gout. About 10% of people with gout make too much urate due to genetic factors. About 90% of people with gout reabsorb too much urate in their kidneys because of genetic factors. […] People who either make too much or excrete too little urate are especially sensitive to foods, drinks or medications that increase urate levels. […] High-fructose corn syrup, which is found in many sweetened soft drinks and other beverages, can raise urate levels too.

Gout is the second most common form of arthritis in New Zealand and more prevalent here than anywhere else in the world. Mori and Pasifika people are particularly affected, mainly due to genetic factors. […] Gout causes sudden attacks of severe pain and swelling in the joints, usually starting in the big toe. If left untreated, more attacks may occur and spread to other joints such as knees, elbows, wrists and fingers. Gout can damage joints and kidneys. […] Gout attacks happen when there is too much uric acid in your blood. Uric acid is produced when proteins called purines are metabolised from food, and most of it usually passes out of the body in your urine. […] Uric acid can build up in your blood if you are overweight, take certain medicines, eat foods containing purines, or have kidney problems. The uric acid turns to sharp, needle-shaped crystals that cause pain and swelling in the joints and can damage cartilage.
- #25 Gout – how to manage it – Arthritis New Zealandhttps://www.arthritis.org.nz/gout-arthritis/
The main reason for high uric acid levels in your blood is because your body cannot get rid of it properly. This could be because of your genes, weight or existing kidney problems. […] Some of the factors that contribute to gout arthritis are: Family history: Some Mori and Pasifika people have genes that make it harder for their bodies to get rid of uric acid. […] Being overweight or obese slows down the removal of uric acid by your kidneys. […] High levels of cholesterol and blood sugar, high blood pressure, and kidney disease can all increase the risk of gout arthritis. […] Gout arthritis can also be diagnosed by testing a sample of fluid around the joint for urate crystals. […] If you are overweight, losing a few kilograms gradually is the most effective treatment for gout arthritis. Avoiding some foods will help lower the level of uric acid in your blood and prevent gout attacks. […] Eat less chicken, meat and seafood these foods contain high levels of purines. […] Drink less alcohol beer is most likely to cause gout attacks as it contains more purines than other forms of alcohol.

Gout, a type of arthritis caused by having too much uric acid in your blood, causes crystals to form in the joints, leading to swelling and pain. Kidney disease is one of the leading causes of gout, especially when the kidneys cannot remove uric acid from the blood. […] Gout is caused by having too much uric acid in your blood. When uric acid builds up in the fluid around your joints, it can form tiny crystals called urate crystals. […] If you have kidney disease, your body may have trouble removing uric acid. This leads to uric acid buildup and crystals, which can cause gout. Gout may also damage the kidneys over time if left untreated. […] One in 10 people with chronic kidney disease (CKD) have gout, and about 1 in 4 people with gout have CKD. When you have CKD, your kidneys do not work as well as they should to filter waste, such as uric acid, out of your body. Uric acid can build up and form urate crystals as your blood is filtered through your kidneys. […] NSAIDs, some of the most common pain-relieving medicines for gout, can also lead to kidney disease over time. Talk to your doctor about how to manage your use of NSAIDs. […] Having certain health conditions can also increase your risk of gout, including chronic kidney disease.

Gout is much more common in people who are overweight. The more overweight you are, the more urate your body produces. […] Gout is about four times more common in men than women. […] Several different conditions are linked to raised urate levels. […] Drinking too much alcohol, especially beer and spirits, can increase your urate levels and your chances of triggering a gout attack. […] Research has shown that vitamin C may slightly reduce uric acid levels in people with gout. […] Research has shown that cherries may reduce the risk of having an acute attack of gout, particularly when taken with allopurinol. […] Allopurinol is the most commonly used ULT. It’s a very effective treatment for most people with gout. […] Febuxostat is a newer drug that reduces the amount of urate made in the body in the same way that allopurinol does. […] Uricosuric drugs, which include sulfinpyrazone, benzbromarone and probenecid, work by flushing out more urate than normal through your kidneys. […] If gout has caused damage to your joints, then treatment will be similar to that for osteoarthritis.

Gout is a condition characterized by the deposition of monosodium urate crystals in the joints or soft tissue. […] Gout progresses through four clinical phases: asymptomatic hyperuricemia, acute gouty arthritis, intercritical gout (intervals between acute attacks) and chronic tophaceous gout. […] Asymptomatic hyperuricemia is common and should not ordinarily be treated. […] Hyperuricemia predisposes patients to both gout and nephrolithiasis, but therapy is generally not warranted in the asymptomatic patient. […] The peak incidence of acute gout occurs between 30 and 50 years of age. […] Gout in women occurs exclusively after menopause. […] The frequency of subsequent acute attacks of gout usually increases over time. […] Tophaceous disease is more likely to occur in patients with the following: a poly-articular presentation, a serum urate level higher than 9.0 mg per dL (535 mol per L) and a younger age at disease onset (i.e., 40.5 years or younger).

Gout is a chronic disorder caused by high levels of uric acid, which can form during the breakdown of molecules called purines that are found in red meat and beer, for example. […] But in a new study reported in Nature Genetics, scientists have analyzed the genetic and health data from millions of people to show that genetic factors are a cause of gout in some patients. […] The researchers are hopeful that since this study has shown that lifestyle is not necessarily the cause of gout, some of the stigma surrounding the disease will lessen. […] Senior study author Professor Tony Merriman of the University of Otago stressed that gout is not the patient’s fault, and it is a chronic disease that has a genetic basis. […] „The myth that gout is caused by lifestyle or diet needs to be busted,” said Merriman. […] And genetic factors play a crucial part in all of those processes, added Merriman.

Gout is caused by high levels of uric acid in the blood. Uric acid is a waste product that usually washes out of the body when you urinate, but if there is too much of it, it can form crystals with sharp edges that inflame joints and cause intense pain. […] Research has shown that gout has a genetic component involving genes that regulate uric acid levels in the body. […] If you eat more purine than the body can handle, or if you don’t excrete enough uric acid when you urinate, gout can result. […] Certain physical and mental health conditions can lead to higher uric acid levels, including stress, fatigue, dehydration, surgery, joint injury, and extreme hot or cold temperatures. […] Foods that contain high purines or raise uric acid levels include certain meats, fish, alcoholic beverages, and foods containing high fructose corn syrup. […] People can develop high uric acid levels due to genetic predisposition and eating foods high in purines.

If gout isnt treated, it can become a long-term problem and affect many joints at once, in both the lower and upper body. At this stage, joints can be damaged, and pain is constant. Tophi can also form in many other parts of the body. […] Uric acid crystals can form kidney stones in some people. These stones are very painful and can hurt the kidneys by: blocking the kidneys from removing wastes, which can cause infection, and scarring the kidneys with their sharp edges. Both problems can lead to CKD, and even kidney failure. […] Refractory gout may not go away with standard treatments. Other medicines may be needed. People with either gout or refractory gout can also have problems with their kidneys. […] Treat kidney disease, obesity, high blood pressure, high blood sugar, and heart disease, because they may increase uric acid and the risk for gout. Review all medicines and supplements with your healthcare professional, as some can increase uric acid.

Gout is also strongly linked to obesity, hypertension (high blood pressure), hyperlipidemia (high cholesterol and triglycerides) and diabetes. […] A high level of uric acid (above 6.8 mg/dL) is one of the essential gout causes. The higher the serum uric acid level, the more likely it is that you’ll develop gout. […] Gout usually begins in men during their 40s through 60s and in women from their 60s through 70s. […] Untreated or undertreated gout, where the uric acid is not decreased to less than 6.0 mg/dL, can lead to permanent bone and joint damage and can cause more frequent and severe gout attacks over time.
