Сибо

Nursing should monitor treatment effectiveness and progress during initial treatment and verify patient compliance. The patient’s calorie intake and weight assessments should be frequently monitored during and after treatment to ensure adequate recovery from their illness. Nursing should follow all these areas and report any concerns to the treating clinician. The pharmacist can assist with agent selection, verifying dosing parameters, and performing medication reconciliation. The pharmacist should also work directly with the clinician and nurse regarding potential drug-condition interactions (eg, opioids, PPIs). SIBO management requires an interprofessional team approach, including physicians, specialists, specialty-trained nurses, and pharmacists collaborating across disciplines to achieve optimal patient results. [Level 5] The overall outcome depends on the underlying condition’s management. If the etiology is not well managed, the overall prognosis is grave.[3] [Level 2]

Pathophysiology

In patients without specific risk factors for SIBO, upper and lower endoscopies are generally performed to rule out other causes like atrophic gastritis and Crohn disease. If endoscopies are normal, imaging studies are done to rule out partial obstruction, diverticula, fistula, or other inflammatory findings. Magnetic enterography increases the sensitivity of diagnosing small intestinal bowel strictures but is costly.

Epidemiology

A bacterial concentration of less than 10 is diagnostic of SIBO, but it is invasive, time-consuming, and expensive, as it is obtained during an upper endoscopy. The results are also poorly reproducible and can lead to false results from patchy bacterial overgrowth or contamination with oropharyngeal flora.[25] Other laboratory findings that support a diagnosis of SIBO may include vitamin levels and markers of malnutrition.[18] Once there is a suspicion of SIBO, additional testing to identify the etiology merits consideration. Anatomic and mucosal abnormalities can be investigated with abdominal imaging and endoscopies. Testing for disorders of abnormal gastrointestinal motility, pancreatic insufficiency, and immunodeficiencies can be considered case-by-case.[3] Rarely, endoscopy with small bowel biopsy is used.

Histopathology

There is no validated gold standard diagnostic test for SIBO.[2] When a patient presents with signs and symptoms concerning SIBO, the diagnosis garners further support with a positive carbohydrate breath test or a bacterial concentration of more than 1000 colony-forming units/mL in a jejunal aspirate culture.[21] A carbohydrate breath test is a noninvasive, fast, and inexpensive test.[22] The test uses the principle that the metabolism of either lactulose or glucose as its carbohydrate substrate by bacteria will produce either hydrogen or methane. This product will then be absorbed and excreted in the patient’s breath.[21] A rise of more than 20 parts per million from baseline in hydrogen within 90 minutes or a methane level of more than ten parts per million are positive results.[21] Results may be falsely positive in patients with short bowel syndrome. Low anaerobic organism counts may result in false negative results. In a review by Romagnuolo J et al., the sensitivity of the glucose breath test is 20-93%, and specificity is 45-86%.[23] The lactose breath test has 17-68% sensitivity and 44-86 % specificity.[24] In an appropriate clinical setting with no risk factors, breath tests can be used for SIBO diagnosis.

Добрата новина е, че според изследователите, билковите лекарства и добавки са също толкова ефективни, колкото и три курса на антибиотична терапия при пациенти, които не реагират добре на рифаксимин.

Etiology

D-lactic acidosis is a rare neurological syndrome that can present with altered mental status, slurred speech, seizures, and ataxia. This syndrome results from bacterial fermentation of unabsorbed carbohydrates. Patients with SIBO associated with short bowel syndrome or a jejunoileal bypass can develop this syndrome.[19] SIBO has been implicated in developing nonalcoholic fatty liver disease and hepatic encephalopathy.[20] Unless severe malnutrition is evident, physical examination in these patients is generally nonrevealing. Rarely succussion splash from fluid-filled lops can be identified.

Антибиотичната терапия със сигурност не е добър избор, защото тя още повече може да влоши състоянието и симптоматиката. Още повече, ако не се приема пробиотик след лечение с антибиотици, рискът за неовладяване на SIBO е голям.

Здравословната и разнообразна чревна микрофлора е изключително важна за здравето и това го доказват все повече съвременни изследвания. Въпреки това, бактериален свръхрастеж в тънките черва – известен под наименованието SIBO, може да причини сериозни здравословни проблеми.

Approximately 45 percent of patients will have recurrent SIBO following antibiotic therapy completion, with higher recurrence rates in older adults, post-appendectomy, and chronic use of proton pump inhibitors.[28] In patients with early recurrence, i.e., within three months, the second course of antibiotics is given. In patients with late recurrence beyond three months, antibiotics are provided only with positive carbohydrate breath testing. Recurrent SIBO is treatable either with the same initial or alternating antibiotic.

Първо пациентът участва в специална диета два дни преди теста. След това пациентът пие разтвор, съдържащ една от захарите, изброени по-горе, която захранва бактериите. Дихателният тест измерва количеството водород и метан, получени от бактериите в резултат на действието им. Тези резултати позволяват на медицински специалист да определи дали има бактериален свръхрастеж.

Ако трябва да ги разграничим, при бактериален свръхрастеж в тънките черва обикновено се появяват умора, гадене и повръщане, подуване на корема и диария, лошо усвояване на хранителни вещества и загуба на тегло.

Diagnoses that produce chronic diarrhea should be in the differential and investigated while evaluating small intestinal bacterial overgrowth. Irritable bowel syndrome (IBS), celiac disease (CD), and inflammatory bowel disease (IBD) all have considerable overlap with SIBO. Irritable bowel syndrome has recurrent abdominal pain related to bowel movements and is associated with a change in stool frequency or appearance.[31] Celiac disease and SIBO have similar clinical symptoms; however, celiac disease will have positive celiac serologies and a negative carbohydrate breath test.[32] Both Crohn disease and SIBO have patchy mucosal inflammation. However, Crohn disease additionally could demonstrate transmural inflammation and granulomas on biopsy and perianal involvement with anal fissures and fistulas.[33]

В тази статия ще се опитаме да направим подробен преглед на диагнозата SIBO и какво може да помогне за облекчаване на състоянието до пълното му излекуване.

An elemental diet can be used in cases where patients cannot tolerate antibiotics or fail to respond to antibiotic treatment (after two times). Limited observational studies suggest remission induction of SIBO symptoms, but poor palatability and high cost limit their use. In an observational study, 80% of patients attained remission (normalization of breath tests and resolution of symptoms) within two weeks.[29]

The etiology of small intestinal bacterial overgrowth is complex. It can be from motility, anatomic, immune, gastric hypochlorhydria, and metabolic and other systemic disorders.

Review the appropriate steps to evaluate a patient with suspected small intestinal bacterial overgrowth (SIBO).

Last Update: April 17, 2023 .

Тънкото черво е най-дългата част от храносмилателния тракт. Това е мястото, където храната се смесва с храносмилателни сокове и хранителните вещества се абсорбират в кръвния поток. Ако се предполага, че има SIBO, малабсорбцията на хранителни вещества, особено на мастноразтворимите витамини и желязо, може лесно да се превърне в проблем.

Important host defense mechanisms against bacterial overgrowth in the small intestine are gastric acid and bile, peristalsis, proteolytic digestive enzymes, intact ileocecal valve, and secretory IgA. When these protective barriers fail, SIBO occurs. Gastric acids and bile destroy and prevent bacteria from passing through the intestines after ingesting food. So, SIBO is associated with achlorhydria.[3] Also, proteolytic enzymes digest and degrade bacteria in the intestines. So, chronic pancreatic insufficiency is associated with SIBO.[3] Migrating motor complexes are responsible for peristalsis and cleansing of the small intestine and prevent retrograde translocation of bacteria.[4] SIBO is associated with disorders of abnormal gastrointestinal motility, such as irritable bowel syndrome, narcotic use, post-radiation enteropathy, hypothyroidism, diabetes mellitus, and scleroderma.[3]

Small intestinal bacterial overgrowth (SIBO) is the presence of excess colonic bacteria in the small intestine. In contrast to the large intestine, the concentration of the bacteria in the small intestine rarely exceeds 1000 organisms/mL. Gastric acid secretion and intestinal motility limit the overgrowth of bacteria in the small intestine. When these protective mechanisms against excessive bacterial growth fail, small intestinal bacterial overgrowth (SIBO) can manifest. This activity reviews the evaluation and management of SIBO and explains the role of the interprofessional team in improving care for patients with this condition.

An intact ileocecal valve and antegrade motility of the ileum prevent retrograde translocation of colonic bacteria.[5] Anatomic abnormalities lead to stasis of the bowels, which may predispose them to SIBO. Such anatomic disorders may include small intestinal diverticulosis, bowel strictures, post-operative adhesions, gastric bypasses with blind intestinal loops, and ileocecal resection.[3] Lastly, the gastrointestinal tract’s secretory immunoglobulin Ig A abundance prevents bacterial proliferation and maintains intestinal immunity. [6] Immunodeficiency disorders, such as acquired immune deficiency syndrome, combined variable immunodeficiency, and IgA deficiency, are associated with an increased risk of SIBO.[7]
