In most cases, this finding rules out the existence of coeliac disease (CD)<a class="elsevierStyleCrossRef" href="#bib0195"><span class="elsevierStyleSup">1</span></a>. CD is an autoimmune disease that mostly develops in genetically predisposed subjects carrying HLA-DQ2/DQ8<a class="elsevierStyleCrossRef" href="#bib0200"><span class="elsevierStyleSup">2</span></a>. To obtain a definitive diagnosis of CD, it is necessary not just to have compatible clinical data, but also to assess other findings, among them: the presence of positive serology, mainly through the detection of IgA or IgG anti-transglutaminase antibodies, or, in cases with negative serology or border levels, the presence of antiendomysial IgA antibodies; a compatible histology, standardised by means of the MARSH Classification<a class="elsevierStyleCrossRef" href="#bib0205"><span class="elsevierStyleSup">3</span></a>; and a clinical response to a gluten-free diet<a class="elsevierStyleCrossRef" href="#bib0200"><span class="elsevierStyleSup">2</span></a>. The new immunohistochemistry and flow cytometry techniques that make it possible to characterise the predominant lymphocyte subpopulations located in the intestinal lamina propria have not been available for that long. Thanks to these techniques, we have been able to establish how the increase of TCR gamma-delta lymphocytes and the decrease of NK CD3+/CD7- lymphocytes are findings specifically associated with CD<a class="elsevierStyleCrossRef" href="#bib0210"><span class="elsevierStyleSup">4</span></a>, thus facilitating the differential diagnosis of other diseases. These techniques are not available for every medical centre. In spite of the aforesaid, CD diagnosis is not always easy to obtain, since there is a small group of patients who have IVA and are responsive to a gluten-free diet but whose antibodies are negative, resulting in the creation of the increasingly widespread seronegative CD concept.</p><p id="par0010" class="elsevierStylePara elsevierViewall">Even though CD is the most frequent cause of IVA<a class="elsevierStyleCrossRef" href="#bib0195"><span class="elsevierStyleSup">1</span></a>, there are other less frequent processes that may trigger it (<a class="elsevierStyleCrossRef" href="#tbl0005">table 1</a>), widening a range of diagnostic possibilities before this histological finding in the context of chronic diarrhoea. To date, there are no studies with a sufficient number of patients to allow us to establish which disorders most frequently trigger these symptoms<a class="elsevierStyleCrossRefs" href="#bib0215"><span class="elsevierStyleSup">5,6</span></a>. In many of these entities, IVA is a constant finding and is part of its diagnostic criteria. However, in others, IVA may be one of multiple histological expressions.

We have excluded from the review some of the most frequent ones such as intestinal lymphoma, bacterial overgrowth or giardiasis, so as to focus on the less frequent conditions that, consequently, spark more controversy in terms of diagnosis and treatment.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Autoimmune enteropathy</span><p id="par0025" class="elsevierStylePara elsevierViewall">Autoimmune enteropathy (AE) consists of severe and prolonged diarrhoea, with clinical and analytical criteria of malabsorption and substantial weight loss due to immunologically-mediated intestinal injury. AE is typically seen in children and young adults<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">7</span></a>. The description of this condition is relatively new, since the first documented case described in children was in 1982<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">8</span></a>, in adults in 1997<a class="elsevierStyleCrossRef" href="#bib0235"><span class="elsevierStyleSup">9</span></a>, and it was not until 2007 when the diagnostic criteria proposed by experts from the Mayo Clinic, which we use nowadays, were established<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">10</span></a>. Cases documented in medical literature are few, which makes it more difficult to set forth an epidemiogical approach, although some authors indicate that it might account for 25% to 30% of the cases with unexplained chronic diarrhoea<a class="elsevierStyleCrossRef" href="#bib0245"><span class="elsevierStyleSup">11</span></a>. AE is most frequent among children between one month and 5 years old, and, unlike other autoimmune diseases, its incidence seems to be higher among males.</p><p id="par0030" class="elsevierStylePara elsevierViewall">In terms of its physiopathology, the most widely approved theory indicates that an enterocyte antigenic interaction with a probable genetic susceptibility prompts them to express, on their surface, HLA type ii molecules, which naturally appear only in antigenic cells, thus activating CD4 and CD8 T cells. They would generate direct damage on the intestinal mucosa, eliminating goblet cells and enterocytes. It is within this context that both IgG anti-enterocyte and anti-goblet cell autoantibodies appear, and they can be identified in plasma by means of immunofluorescence methods. Although it might be appealing to identify them in a diagnosis, they are estimated to be present in just 50% of AE cases. Moreover, these autoantibodies have also been identified in other enteropathies such as allergy to cow-milk proteins or inflammatory bowel disease, which reduces its specificity. It is currently not altogether clear what the true role played by autoantibodies in AE is, despite the fact that they might be more of an immune reaction to enteric damage than its causative agent<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">12</span></a>.</p><p id="par0035" class="elsevierStylePara elsevierViewall">The extra intestinal condition in AE might affect organs such as the kidneys, the liver or the lungs, as well as systems such as the haematopoietic, musculoskeletal and endocrine.

The other important element in this treatment is glucocorticosteroids, with the possibility of administering methylprednisolone in 1 mg/kg/day or similar doses. Due to their systemic side effects, it has been suggested that budesonide 9 mg/day might be used, in 3 doses of 3 mg by mouth, mainly with an ileocolic effect; considering that the condition tends to affect the digestive tract in its entirety, some authors suggest that in order for the drug to have an effect on the entire small intestine, the first 3 mg dose of the day should be administered in the morning with food and chewed before swallowing, the second 3 mg dose should be administered at noon also with food but without the need to chew, and finally, the last 3 mg dose should be administered at night, with the entire capsule<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">10</span></a>. In patients refractory to reducing or discontinuing the glucocorticosteroid treatment, immunosuppressant drugs can be used, but due to the lack of experience in their use for treating this disease, it is not possible to recommend which drug and dose to use, since each clinician should make that decision on a case-by-case basis, based on the side-effect pattern of these drugs, and on his or her own experience with each one of them.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Collagenous sprue</span><p id="par0060" class="elsevierStylePara elsevierViewall">Collagenous sprue (CS) is a chronic-type diarrhoea caused by food malabsorption in patients with IVA, and a subepithelial collagen band detected by means of the duodenum biopsy.

However, and despite the extended use of the term, we did not find more than 120 reported cases in medical literature after reviewing it extensively. This might be due to the debate, persisting to date, as to whether CS is an entity in itself, or whether it is part of the CD spectrum. Those defending the first option state that they are 2 conditions where treatment, evolution and histology are different; however, in the face of an absence of commonly accepted diagnosed criteria and considering that up to 30% of CD cases present a small collagen band (less than 5 μm), it might lead us to believe that it is part of the refractory CD range. Although it has been suggested that it might be a paraneoplastic manifestation of tumours from other levels<a class="elsevierStyleCrossRefs" href="#bib0275"><span class="elsevierStyleSup">17,18</span></a>, the immunomediated hypothesis seems to be the most probable one, since up to 70% of CS cases present associated autoimmune diseases and response to glucocorticosteroids in these patients has been demonstrated.

Besides the infection by <span class="elsevierStyleItalic">Giardia lamblia</span>, it is not unusual, however, to find other parasite infections such as those caused by <span class="elsevierStyleItalic">Cryptosporidium</span> and <span class="elsevierStyleItalic">Strongyloides</span>, which also lead to a similar clinical condition.</p><p id="par0090" class="elsevierStylePara elsevierViewall">From a histological viewpoint, CVID is characterised by presenting an IVA pattern in the duodenum, with absence of plasma cells in the lamina propria, which confirms the diagnosis and makes it possible to establish differences with CD (<a class="elsevierStyleCrossRef" href="#tbl0010">table 2</a>). Another characteristic anatomopathological finding is nodular lymphoid hyperplasia, which will also be present both in the stomach and colon, and that is not pathognomonic of this disease, since it can be frequently found in healthy adults. Cases of colitis histologically similar to Crohn's disease or ulcerative colitis have been described, along with others that are even indistinguishable regarding findings described for graft-versus-host disease, with marked apoptosis and lymphocytosis in the intestinal crypts. The main difference between these entities is the absence of plasma cells that are characteristic of CVID.</p><p id="par0095" class="elsevierStylePara elsevierViewall">It is important to know that, besides the intestinal condition that characterises CVID, these patients have a higher propensity to suffer oncological diseases such as intestinal lymphoma or gastric and colic adenocarcinoma<a class="elsevierStyleCrossRef" href="#bib0305"><span class="elsevierStyleSup">23</span></a>.</p><p id="par0100" class="elsevierStylePara elsevierViewall">The treatment of choice should be intravenous infusion of gamma globulins. Nonetheless, when it comes to establishing a definitive diagnosis and treatment, it should be borne in mind that CD can also be associated with CVID, since the villous atrophy present in these patients may, at times, be due to the presence of CD and, thus, should respond to a gluten-free diet<a class="elsevierStyleCrossRef" href="#bib0310"><span class="elsevierStyleSup">24</span></a>.</p></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0020">Drug-induced enteropathy</span><p id="par0105" class="elsevierStylePara elsevierViewall">Villous atrophy enteropathy secondary to drugs was a very atypical problem until recent years, having been described only with immunosuppressant medications such as mycophenolate mofetil and azathioprine in patients who are receivers of solid organ transplants<a class="elsevierStyleCrossRef" href="#bib0315"><span class="elsevierStyleSup">25</span></a>. However, since Rubio-Tapia et al. published their work in 2012 describing a series of 22 patients with severe villous atrophy enteropathy treated with olmesartan <a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">26</span></a>, the interest attracted by this clinical condition has increased and, therefore, more cases have been increasingly included in medical literature. To date, a total of 45 patients have been reported to have it<a class="elsevierStyleCrossRefs" href="#bib0325"><span class="elsevierStyleSup">27–30</span></a>. Enteropathy caused by olmesartan is characterised by severe diarrhoea and significant weight loss, and it takes place in patients undergoing chronic treatment with this drug, usually months or even years before the symptoms appear.</p><p id="par0110" class="elsevierStylePara elsevierViewall">Although the physiological mechanism accounting for this phenomenon has not been clearly established, it seems that the drug interaction with immune system elements, such as the synthesis of proinflammatory molecules like transforming growth factor-β (TGF-β) might account for the histological findings that appear. It is not known either whether there is a genetic predisposition for it<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">26</span></a>.</p><p id="par0115" class="elsevierStylePara elsevierViewall">From a histological viewpoint, it might be indistinguishable from CD, although it typically starts with an substantial clinical and laboratory impact, presenting total or subtotal villus atrophy and an increase of intraepithelial lymphocytes in duodenum biopsies. Other findings, however, such as those overlapping with CS, or an isolated increase of intraepithelial lymphocytes might be the only anatomopathological findings for this entity.</p><p id="par0120" class="elsevierStylePara elsevierViewall">Clinically, it is characterised by severe diarrhoea, with intestinal malabsorption that does not respond to a gluten-free diet and that disappears between 1-2 weeks after the drug was suspended.</p><p id="par0125" class="elsevierStylePara elsevierViewall">To establish its diagnosis, it is not necessary to obtain a histological confirmation of healing, which is achieved after many months, and it could be enough just to demonstrate a clinical response, obtaining symptom resolution once the drug has been suspended (<a class="elsevierStyleCrossRef" href="#fig0005">fig. 1</a>).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0025">Eosinophilic gastroenteritis</span><p id="par0130" class="elsevierStylePara elsevierViewall">Eosinophilic gastroenteritis (EG) is a rare disease that can affect the entire digestive tract, from the oesophagus to the rectum, though the organ that is most frequently involved is the stomach, followed by the proximal tracts of the small intestine. It is characterised by the presence of a large number of eosinophils in the gastric or intestinal mucosa and the peripheral blood, with no other disease accounting for it<a class="elsevierStyleCrossRef" href="#bib0345"><span class="elsevierStyleSup">31</span></a>. It is generally diagnosed during the third and fourth decades of life, with a slight preference for the male gender<a class="elsevierStyleCrossRef" href="#bib0350"><span class="elsevierStyleSup">32</span></a>. However, its epidemiological approach is very complex due to the scarce casuistry published to date, with less than 300 cases, and its longest series consisting of 31 patients<a class="elsevierStyleCrossRef" href="#bib0355"><span class="elsevierStyleSup">33</span></a>.</p><p id="par0135" class="elsevierStylePara elsevierViewall">The most-widely accepted physiopathological theory is the one stating that EG could be the result of a hypersensitivity reaction. The presence of eosinophilia and elevated IgE levels in many patients supports this theory. Besides, it has also been proved that up to 50% of EG patients had a history of asthma, eczema, or another clinical allergy<a class="elsevierStyleCrossRef" href="#bib0360"><span class="elsevierStyleSup">34</span></a>. Many inflammatory molecules have been described, among them, interleukin 3, interleukin 5, and eotaxin, which may perpetuate the eosinophilic inflammatory infiltration that these patients have in their digestive tract<a class="elsevierStyleCrossRef" href="#bib0365"><span class="elsevierStyleSup">35</span></a>.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Symptoms are quite varied and they differ regarding condition stage and its predominant location. In most patients, symptoms are present for years and are quite varied, ranging from dysphagia, if the condition is predominantly oesophagus, diarrhoea, with loss of fat (steatorrhea) and proteins, and symptoms of severe intestinal pseudo-obstruction in those patients with a mostly enteric condition. This disease may also present chronic abdominal pain, growth retardation or amenorrhea in adolescent patients. Cases with subserosa damage may start by presenting ascites with elevated eosinophils in peritoneal fluid<a class="elsevierStyleCrossRef" href="#bib0370"><span class="elsevierStyleSup">36</span></a>.</p><p id="par0145" class="elsevierStylePara elsevierViewall">To establish a diagnosis, patients must have gastrointestinal symptoms and an eosinophil infiltration in the digestive tract, but other causes of eosinophilia, such as parasitic infections or hypereosinophilic syndrome, should be discounted. It is important to know that eosinophilia is present in 20%-80% of patients; therefore, its absence does not exclude the diagnosis and, hence, it is not part of the necessary criteria. An increase of eosinophils in the duodenum lamina propria will be histologically demonstrated (more than 50 per field), with crypts hyperplasia and atrophy of intestinal villus. Other typical findings will be the presence of fibrosis and an eosinophil cationic protein deposit<a class="elsevierStyleCrossRef" href="#bib0345"><span class="elsevierStyleSup">31</span></a>.</p><p id="par0150" class="elsevierStylePara elsevierViewall">Glucocorticosteroids are the initial treatment of choice for these patients, with an approximate response rate of 90%<a class="elsevierStyleCrossRef" href="#bib0345"><span class="elsevierStyleSup">31</span></a>. However, the absence of clinical trials and long-term controlled studies prevents making recommendations on treatment duration and maintenance dose. The use of other drugs, such as cromolyn sodium<a class="elsevierStyleCrossRef" href="#bib0375"><span class="elsevierStyleSup">37</span></a> or montelukast (stabilizer of mast cells membrane)<a class="elsevierStyleCrossRef" href="#bib0380"><span class="elsevierStyleSup">38</span></a>, has been suggested, with no clear usage indications established to date. Since EG has always been associated with the presence of food allergies, it seems reasonable to do skin tests using common allergens and, in case of positive results, remove them from the patient's diet.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Summing up, IVA is frequently seen in patients with chronic diarrhoea, and is not always associated with CD, particularly in those patients with negative antibodies who do not respond to a gluten-free diet. Obtaining a complete medical history must be insisted upon, listing all of the drugs that the patient is taking, even those he has been taking for years. The presence of autoimmune diseases may be indicative of enteropathies, such as CS or AE. A medical history indicating allergic reactions, asthma or eczema might orient the diagnosis towards EG. In most entities with IVA, the physiological mechanisms are related to immune system deregulation and, so, the treatment of choice is glucocorticosteroids. For this reason, once CD, infectious diseases and intestinal lymphoma or a drug-induced enteropathy are all reasonably ruled out, systemic treatment with corticosteroids, along with an adequate nutritional support, should be the first therapeutic step.</p></span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0030">Conflict of interest</span><p id="par0160" class="elsevierStylePara elsevierViewall">The authors declare that there are no conflicts of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:7 [ 0 => array:2 [ "identificador" => "sec0005" "titulo" => "Autoimmune enteropathy" ] 1 => array:2 [ "identificador" => "sec0010" "titulo" => "Collagenous sprue" ] 2 => array:2 [ "identificador" => "sec0015" "titulo" => "Common variable immunodeficiency" ] 3 => array:2 [ "identificador" => "sec0020" "titulo" => "Drug-induced enteropathy" ] 4 => array:2 [ "identificador" => "sec0025" "titulo" => "Eosinophilic gastroenteritis" ] 5 => array:2 [ "identificador" => "sec0030" "titulo" => "Conflict of interest" ] 6 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2014-04-09" "fechaAceptado" => "2014-05-08" "NotaPie" => array:1 [ 0 => array:2 [ "etiqueta" => "☆" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">Please cite this article as: Téllez Villajos L, Crespo Pérez L, Cano Ruiz A.
