Why is IBS considered a last ditch diagnosis?
IBS has a reputation for being a “last-ditch” diagnosis, given to patients suffering from gut problems who do not fit the bill for any specific gastrointestinal disease. Due to a lack of validated diagnostic biomarkers, an IBS diagnosis has historically been given only when other gastrointestinal conditions have been ruled out. This process costs patients thousands of dollars in medical expenses while at the same time failing to provide any useful direction regarding treatment.
What is the role of anti-CDT antibodies in the gut?
Anti-Cdt antibodies cross-react with vinculin that is present in the gut, leading to the production of anti-vinculin antibodies. ( 4) Anti-vinculin antibodies destroy vinculin, disrupting epithelial tight junction proteins and damaging nerve cells. This causes leaky gut and dysmotility.
What is the name of the doctor who studies IBS?
Dr. Pimentel, an associate professor of medicine at Cedars-Sinai Medical Center, has made it his life’s work to better understand IBS and small intestinal bacterial overgrowth (SIBO). He and I previously discussed SIBO on my podcast, Revolution Health Radio. Recently, I had the honor of hosting Dr. Pimentel again on the show. This time, we discussed his groundbreaking research indicating that diarrhea-predominant IBS (IBS-D) and IBS that is predominantly characterized neither by diarrhea nor constipation, or mixed IBS (IBS-M), are triggered by food poisoning, resulting in the production of antibodies that damage the enteric nervous system and trigger IBS.

What is metastatic Crohn's disease?
Metastatic Crohn’s disease is a cutaneous granulomatous non-caseating lesion that occurs in patients with CD. The clinical presentation and microscopic findings are necessary for accurate diagnosis. Two cases of metastatic CD with involvement of the retro-auricular area have been described [9, 10]. In one case, a patient with perianal CD received oral steroids and infliximab and the therapy resulted in rapid remission of the cutaneous auricular lesion and Crohn’s disease [9]. In the other case, a 10-year-old boy presented with bilateral chronic granulomatous external otitis and obliteration of the external auditory canal. Histopathologic findings suggested cutaneous CD and a subsequent gastroenterologic workup confirmed the diagnosis of CD [11].
Can IBD cause ear disease?
IBD can be associated with ear disease in all components of the ear: external, middle and inner ear (Table 1). While external and middle ear disease can be due to associated conditions, the most common ear manifestation of IBD is in the inner ear, largely as a result of AIED, and especially in UC. This can be managed effectively through immunosuppression, initially through corticosteroids and stepping up to anti-TNF therapy, and if that fails, cochlear implantation. There are also other associated conditions that may affect the inner ear in IBD patients, such as Cogan’s syndrome and Melkersson-Rosenthal syndrome, but these are very rare. In addition, while there is still no evidence to suggest that IBD treatment is associated with ear disease, this requires further investigation as the treatments are recognized to be ototoxic.
Is Cogan's syndrome autoimmune?
Cogan’s syndrome is a rare chronic autoimmune inflammatory disease, characterized by bilateral sensorineural hearing loss, vestibular symptoms, non-syphilitic interstitial keratitis and aortitis. In many patients, Cogan’s syndrome is related with other autoimmune disease such as rheumatoid arthritis, Sjogren’s syndrome and IBD. A retrospective observational study was done with 22 concomitant Cogan’s syndrome-IBD cases, with six patients with underlying UC and 16 with CD. IBD was diagnosed before the onset of Cogan’s syndrome in all of these patients, with a mean duration of IBD of 8.7 years. Also, IBD activity did not seem to trigger Cogan’s syndrome, as 11 of 22 patients had inactive disease at the time of Cogan’s syndrome diagnosis. Immunosuppressive treatment does not seem to prevent the onset of disease, as sixteen patients received immunosuppressive agents, of whom six received anti TNF-a therapy [42]. Corticosteroids are often effective in controlling the disease. If the patient does not improve, immunosuppressive drugs, such as methotrexate and azathioprine, are used. Infliximab is a promising treatment option, enabling steroid tapering and leading to improvement in auditory/ocular disease, with better outcomes if administered in the early stages of the disease [43]. Therefore, Cogan’s syndrome could be another indication for use of anti-TNF-a agents in patients with IBD.
Is ear inflammation a autoimmune disease?
The ear has been associated with a wide variety of other systemic autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis, Behcet’s disease and Sjogren’s syndrome. Three possible mechanisms for autoimmune related otologic disorders have been suggested: 1) autoantibody binding to type II collagen or other otologic components (type II immunologic injury); 2) immune complex formation leading to vasculitis (type III); 3) T cell-mediated auto reactivity to inner ear membranous elements (type IV) [1]. There is evidence to support external, middle and inner ear involvement in IBD. In this systematic review, we present the various types of otologic disorders that are correlated with IBD, and the therapy and management of these diseases.
Is immunosuppressive therapy necessary for remission and maintenance of IBD?
While immunosuppressive therapy is necessary for the remission and maintenance of IBD, this increases the risk of infectious complications. Duque et al described a 27-year-old female with CD treated with azathioprine and infliximab. She complained of left otalgia, otorrhea and fever with no gastrointestinal complaints. She suffered from necrotizing external otitis and she was successfully treated with ciprofloxacin (500 mg IV for 3 weeks and then oral for another 3 weeks), ceftazidime (1,000 mg IV for 6 weeks), as well as topical therapy with alcohol and aspiration of secretions. Necrotizing external otitis is a rare but acknowledged complication of external otitis and affects predominantly immunocompromised patients and diabetics [18].
Is SNHL an IBD?
In a retrospective observational study with 32 IBD patients with otologic problems, SNHL was found in 22 of 32 patients. Nineteen of 22 patients had no identifiable causes for SNHL. Only one patient responded to medical treatment [21]. Also, it seems that subclinical SNHL is common in IBD patients. The presence of subclinical SNHL was investigated in 39 patients with IBD (18/UC, 21/CD) and 25 healthy controls and the findings between two groups were compared. A significant difference was found at high frequencies in UC patients, at frequencies of 2, 4 and 8 kHz and in CD patients at the frequency of 4 kHz [22]. However, there was no difference when Kalyoncu et al performed otoscopy, tympanometry and pure tone tympanometry in 24 pediatic patients with IBD and 20 healthy children and compared the findings between these groups [23].
