Seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered. Recently, a new clinical entity responsible for seronegative villous atrophy was described olmesartan-induced sprue-like enteropathy.

Objectives: patients with villous atrophy (va) and negative celiac disease (cd) serologies pose a diagnostic and therapeutic dilemma. When a definitive etiology for va is not determined, patients are characterized as having unclassified sprue (us), the optimal management of which is unknown.
Villous atrophy is the destruction of your intestinal villi, the tiny fingers of cells that absorb nutrients from food.
3 4 however, there was no relevant drug history in this case. A recent large prospective study in the uk evaluated 200 new patients with seronegative villous atrophy over a 15-year period. Seronegative coeliac disease was diagnosed in 31% of cases with the remaining 69% due to seronegative non-coe-liac.
To define the prevalence and features of seronegative compared to seropositive celiac disease, and to establish whether celiac disease is a common cause of seronegative villous atrophy. Methods starting from 810 celiac disease diagnoses, seronegative patients were retrospectively characterized for clinical, histological and laboratory findings.

Results: normal villous morphology was noted in 17 children who were ema positive, and villous atrophy was noted in 42 children who were ema positive. These children were comparable in all measured variables regardless of the degree of enteropathy, but differed significantly from the seronegative control subjects.
The diagnostic workup of seronegative villous atrophy (snva) must ensure exclusion of other enteropathies before starting patients on a lifelong gluten-free diet. This is crucial in order to ensure that patients are not given the wrong diagnosis, which in turn can have implications for their inappropriate treatment and long-term morbidity.
Seronegative intestinal villous atrophy, including those that are nonresponsive to a gluten-free diet, is a diagnostic challenge. In these cases, before establishing the diagnosis of seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered.
Seronegative villous atrophy (snva) is a diagnostic and therapeutic dilemma. The causes of snva are vast but can be broadly grouped into seronegative coeliac disease (sncd) and seronegative non-coeliac disease (sn-non-cd). To date no study has systematically evaluated all newcomers with snva.
Dec 4, 2020 “previous work detailing the prevalence of seronegative celiac disease [ced], diagnosis of seronegative villous atrophy, and management.
Background seronegative villous atrophy (snva) is commonly attributed to coeliac disease (cd). More recently angiotensin-2-receptor-blockers (a2rbs) have been reported as an association but data on snva have been limited to centres evaluating complex case referrals and not snva in general.

Seronegative ced is defined as patients with or without gastrointestinal signs and symptoms of ced in the presence of villous atrophy and compatible genetics and without iga ttg, iga dgp, and iga ema, who show clinical and histologic responses to the gfd and for whom other etiologies have been examined.
Although rare, seronegative celiac disease is the most common cause of seronegative villous atrophy with a high median age at diagnosis; a close association with malabsorption and flat mucosa; and a high prevalence of autoimmune disorders. Physicians treating seronegative villous atrophy should consider seronegative celiac disease as a possibility.
Grade a/type 1: increased intraepithelial lymphocytes but no villous atrophy seen in patients on gluten free diet (suggesting minimal amounts of gluten or gliadin are being ingested); patients with dermatitis herpetiformis; family members of celiac disease patients, not specific, may be seen in infections.
Background: seronegative villous atrophy (snva) is commonly attributed to coeliac disease (cd).

Villous atrophy: decrease in villous height, alteration of normal crypt/villous ratio (3:1) until total disappearance of villi; this assessment requires proper orientation of the biopsies diagnostic categories are based on these elementary lesions: modified marsh-oberhuber classification of histologic findings in celiac disease.
The clinical and phenotypic assessment of seronegative villous atrophy; a prospective uk centre experience evaluating 200 adult cases over a 15 year period (2000-2015) abstract background: seronegative villous atrophy (snva) is commonly attributed to coeliac disease.
[8][9][10][11][12][13][14][15] this clinical entity is termed seronegative villous atrophy (snva), of which the causes can be broadly grouped into cd or non-cd related.
Degaetani et al 6 studied 72 patients with “seronegative villous atrophy” at a tertiary care center; the condition was defined by villous blunting on duodenal biopsy and negative celiac serology results. Interestingly, the two most common diagnoses in these patients were seronegative celiac disease (28%) and medication-related villous.
Celiac disease is the most important cause of intestinal villous atrophy. Seronegative intestinal villous atrophy, including those that are nonresponsive to a gluten-free diet, is a diagnostic challenge. In these cases, before establishing the diagnosis of seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered.
A study of nonceliac villous atrophy cases published before the description of olmesartan-associated enteropathy described unclassifiable immune mediated enteropathy as the etiology of 10 (33%) of 30 patients with nonceliac.
Patients with suspected celiac disease who are seronegative but have villous atrophy and genetic risk factors for celiac disease must undergo endoscopic evaluation after 1–3 years on a gluten-free diet to evaluate improvements in villous atrophy. A diagnosis of seronegative celiac disease can then be confirmed based on clinical and histologic.
Introduction villous atrophy (va) in the presence of positive coeliac serology (ema and ttg) is highly predictive of coeliac disease (cd). However, diagnostic challenges may arise in those where va is associated with a negative serology. Methods patients presenting with seronegative va (both ema negative and ttg 30) were prospectively recruited.
And is characterized by seronegative villous atrophy and severe ileojejunitis in endoscopic evaluation. Small bowel mucosal lesions are widely documented in our case, which was rarely done in previous works. As far as we know, this is the first case reporting olmesartan‐induced macroscopic colitis.
Patients with villous atrophy (va) and negative celiac disease (cd) serologies pose a diagnostic and therapeutic dilemma. Sa1330 seronegative villous atrophy: a single center experience.
Sixty‐seven consecutive patients with seronegative villous atrophy were included. Duodenal biopsies to assess tcrγδ + and cd3 − by flow cytometry were performed at the index endoscopy. Coeliac lymphogram was defined as an increase in tcrγδ + plus a decrease in cd3 − intraepithelial lymphocytes.
Background duodenal villous atrophy (dva) is a key diagnostic finding in coeliac disease (cd). However, the differential diagnosis for this finding is broad. Aim to identify conditions causing noncoeliac enteropathy (nce) with villous atrophy and methods to differentiate between cd and nce in clinical practice.
Abstract leucopenia and diarrhoea are the main side effects observed after the use of mycophenolate mofetil (mmf) in renal‐transplant patients.
Refractory coeliac disease (rcd) is characterized by the persistence or recurrence of symptoms and signs of malabsorption associated with villous atrophy in patients with coeliac disease who have adhered to a strict gluten-free diet (gfd) for more than 12 months. 1–3 serology is usually negative or, in a small percentage of cases, positive at a low titre.
