• #1 Etiology, Pathogenesis, and Diagnosis of Interstitial Cystitis

  https://pmc.ncbi.nlm.nih.gov/articles/PMC1476007/

  Interstitial cystitis (IC) is a bladder syndrome of unknown etiology. The cause of IC is most likely multifactorial and includes genetic and environmental factors. […] The pathogenesis and etiology of interstitial cystitis remain incompletely defined. However, there is an emerging consensus as to the central role of epithelial dysfunction, bladder sensory nerve up-regulation, and mast cell activation in the genesis of IC. […] IC has many features of an autoimmune diseasechronicity, exacerbations and remissions, clinical response to steroids/immunosuppressives, the high prevalence of antinuclear antibodies, and association with other autoimmune syndromes. Current evidence suggests that autoimmune phenomena (bladder antibodies, etc) are epi-phenomena that occur as a result of local bladder cellular damage. […] The multifactorial etiology of IC and its complex, interrelated pathogenesis involving the bladder urothelium, sensory nerves, and mast cells are being increasingly defined.

  The exact cause of interstitial cystitis isn’t known, but it’s likely that many factors contribute. For instance, people with interstitial cystitis may also have a defect in the protective lining (epithelium) of the bladder. A leak in the epithelium may allow toxic substances in urine to irritate your bladder wall. […] Other possible but unproven contributing factors include an autoimmune reaction, heredity, infection or allergy.

• #1 Interstitial Cystitis – familydoctor.org

  https://familydoctor.org/condition/interstitial-cystitis/

  Interstitial cystitis is chronic inflammation of the bladder. People who have the condition have a bladder wall that is irritated and inflamed (sore and red). This inflammation can scar the bladder or make it stiff. A stiff bladder can’t expand as urine fills it. In some cases, the walls of the bladder may bleed slightly. Some people get sores in the bladder lining. More than 3 million American women and 1 million men have interstitial cystitis. […] Doctors don’t know exactly what causes interstitial cystitis. However, they do know that it isn’t caused by bacterial or viral infections that can be tracked through standard tests. […] A defect in the lining of the bladder might cause the condition. Normally, the lining protects the bladder wall from the toxic effects of urine. In about 70% of the people who have interstitial cystitis, the protective layer of the bladder is “leaky.” This may let urine irritate the bladder wall, causing interstitial cystitis. If the urine contains an abnormal substance, it can be even more irritating. […] Other possible causes may be an increase of histamine-producing cells in the bladder wall (allergy). Or it could be caused by an autoimmune response. This is when your body mistakenly fights something healthy elsewhere in your body.

• #1 What Is Interstitial Cystitis?

  https://www.icliniq.com/articles/kidney-and-urologic-diseases/interstitial-cystitis

  The exact cause of interstitial cystitis has yet to be discovered correctly. It is usually multifactorial. It may also be due to an autoimmune reaction, genetics, infection, or allergic response. […] People with interstitial cystitis may also have a defect in the bladder’s protective lining. Any leakage or damage in the epithelium may allow the toxic substances in urine to irritate the bladder. This defect in the bladder may allow the irritating substances in the urine to enter by penetrating the bladder directly. […] A specific type of inflammatory cell known as a mast cell tends to release histamine and other chemicals. These chemicals can cause interstitial cystitis. […] Alterations in the nerves that carry bladder sensations. These alterations might cause pain. […] The body’s immune system begins to attack the bladder. This might be similar to other autoimmune conditions.

  https://www.aafp.org/pubs/afp/issues/2001/1001/p1199.html

  Interstitial cystitis is a chronic, severely debilitating disease of the urinary bladder. […] While the exact cause of interstitial cystitis is not known, it is probably related to many factors, including autoimmune, allergic and infectious etiologies. […] According to one widely held theory, the symptoms of interstitial cystitis originate from a defect in the glycosaminoglycan component of the mucin layer that covers and protects the bladder urothelium. […] A deficiency of this layer is thought to cause interstitial cystitis. […] Low rates of urinary glycosaminoglycan excretion have been found in patients with interstitial cystitis. […] Another working theory of interstitial cystitis etiology includes mast cell abnormalities. […] To date, no convincing evidence confirming a viral, bacterial or fungal cause of interstitial cystitis has been found.

• #1 Interstitial cystitis – Wikipedia

  https://en.wikipedia.org/wiki/Interstitial_cystitis

  The cause of interstitial cystitis is unknown. […] The cause of IC/BPS is not known. However, several explanations have been proposed and include the following: autoimmune theory, nerve theory, mast cell theory, leaky lining theory, infection theory, and a theory of production of a toxic substance in the urine. […] Other suggested etiological causes are neurologic, allergic, genetic, and stress-psychological including exposure to abuse in childhood or adulthood. […] An infection may then predispose those people to develop IC. […] Evidence from clinical and laboratory studies confirms that mast cells play a central role in IC/BPS possibly due to their ability to release histamine and cause pain, swelling, scarring, and interfere with healing. […] Research has shown a proliferation of nerve fibers is present in the bladders of people with IC which is absent in the bladders of people who have not been diagnosed with IC.

  https://www.uofmhealth.org/conditions-treatments/adult-urology/interstitial-cystitisic-bladder-pain-syndrome

  Experts do not know exactly what causes IC/BPS, but there are many theories, such as: […] A defect in the bladder tissue, which may allow irritating substances in the urine to penetrate the bladder. […] A specific type of inflammatory cell, called a mast cell. This cell releases histamine and other chemicals that lead to IC/BPS symptoms. […] Something in the urine that damages the bladder. […] Changes in the nerves that carry bladder sensations so pain is caused by events that are not normally painful (such as bladder filling). […] The body’s immune system attacks the bladder. This is similar to other autoimmune conditions. […] No specific behaviors (such as smoking) are known to increase your risk of IC. Having a family member with IC/BPS may increase your risk of getting IC/BPS. Patients with IC/BPS may have a substance in the urine that inhibits the growth of cells in the bladder tissue. So, some people may be more likely to get IC/BPS after an injury to the bladder, such as an infection.

  Researchers do not know the exact cause of interstitial cystitis. However, some possible causes include chronic inflammation and stress, fibrosis, and problems with the immune system. […] A 2024 review of research notes that scientists do not fully understand the exact causes of interstitial cystitis. […] However, some causes of interstitial cystitis may include: problems with the immune system, such as autoimmunity, in which the immune system mistakenly attacks healthy tissues in the body; chronic inflammation; bladder fibrosis, or the formation of permanent scar tissue in the bladder; chronic stress; neurogenic inflammation, which refers to inflammation resulting from neuron activity in the peripheral nervous system rather than immune system activity; problems with the pelvic floor; heightened pain sensitivity due to an increase in gray matter volume in the outer layer of the brain; problems with the specialized cells that line the urinary tract; mast cell overactivity or other problems with mast cells, which are a type of immune cell; abnormal development of blood vessels, which may appear as bladder hemorrhages during cystoscopy; increase in sensitivity or rapid increase in the amount of sensory afferent fibers, which are a type of nerve fiber that help carry sensory information to the brain.

[…] In addition, interstitial cystitis is associated with the following chronic illnesses: […] Inflammatory bowel disease […] Systemic lupus erythematosus […] Irritable bowel syndrome […] Fibromyalgia […] Atopic allergy. […] Other autoimmune conditions have also been shown to bear resemblance or be associated with IC/BPS. […] Psychiatric conditions associated with interstitial cystitis include anxiety disorder, depression, and adjustment reactions.

• #1 Bladder Pain Syndrome and Interstitial Cystitis: Definition and Etiology

  https://www.urology-textbook.com/interstitial-cystitis.html

  Increased stimulation of pain fibers may cause a neurogenic inflammation. Increased concentrations of mediators of neurogenic inflammation, such as substance P, neurokinin A, and calcitonin gene-related protein, could be detected in interstitial cystitis. The inflammatory cascade of neurogenic inflammation is indistinguishable from a bacterial or allergic inflammation cascade. The threshold at which the bladder filling is perceived as painful is significantly reduced in patients with interstitial cystitis. Recurring pain stimuli could trigger the neurogenic inflammatory cascade, and maladaptive mechanisms may lead to chronic pain syndrome. […] The relationship between interstitial cystitis and autoimmunity is contradictory. It was possible to detect autoantibodies against the urinary bladder, but the laboratory findings’ specificity is controversial. Secondary autoimmune phenomena in response to inflammation are also possible. Although the non-specific inhibition of the inflammatory cascade is part of the effective therapy, the exact role of autoimmunity remains unclear. […] Psychological stress and derived symptoms are interpreted as a response to the disease (voiding almost hourly and suffering from chronic pain).

  It is thought that this damage to the bladder wall then allows particles in the urine, such as potassium, to leak into the bladder lining. […] Researchers speculate that one reason for this continued damage to the bladder is that normal repair of the lining of the bladder does not occur in patients who develop IC. […] Research indicates that this might be due to a protein called antiproliferative factor (APF). […] Studies have shown that APF is produced by the cells of patients with IC, but not by the cells of healthy people. […] APF prevents the growth of bladder cells and the bladder may be unable to repair itself when APF is present.

• #1 Bladder Pain Syndrome and Interstitial Cystitis: Definition and Etiology

  https://www.urology-textbook.com/interstitial-cystitis.html

  Many attempts to prove an infectious etiology for interstitial cystitis have failed. Antibiotic treatment did not prove to be effective. It is still possible that harmless organisms trigger an autoimmune reaction against components of the bladder wall. This hypothesis is supported by increased mast cells and increased concentrations of their mediators in the urothelium and bladder wall. The central role of mast cells in the inflammatory cascade of interstitial cystitis is undisputed in IC research. Overall, the infectious theory is seen at best as a trigger for interstitial cystitis. […] Studies have found an antiproliferative activity in the urine of patients with interstitial cystitis. The putative factor is called antiproliferative factor (APF), which is most probable produced in the bladder and belongs the frizzled protein family. Any injury of the bladder (infection, trauma or overdistension) may lead in susceptible patients (with APF) to bladder pain syndrome or interstitial cystitis. Further studies are needed to assess the clinical significance of APF.
