Evolutionary Developments in Interpreting the Gluten-Induced Mucosal Celiac Lesion: An Archimedian Heuristic. Nutrients 2017; 9:nu9030213.

Abstract
The evolving history of the small intestinal biopsy and its interpretation—and misinterpretations—are described in this paper. Certain interpretative errors in the technical approaches to histological assessment are highlighted—even though we may never be rid of them. For example, mucosal “flattening” does not reduce individual villi to their cores, as still seems to be widely believed. Neither is the mucosa undergoing an atrophic process—since it can recover structurally. Rather, the intestinal mucosa manifests a vast hypertrophic response resulting in the formation of large plateaus formed from partially reduced villi and their amalgamation with the now increased height and width of the inter-villous ridges: this is associated with considerable increases in crypt volumes. Sections through mosaic plateaus gives an erroneous impression of the presence of stunted, flat-topped villi which continues to encourage both the continued use of irrelevant “atrophy” terminologies and a marked failure to perceive what random sections through mosaic plateaus actually look like. While reviewing the extensive 40+ year literature on mucosal analysis, we extracted data on intraepithelial lymphocytes (IEL) counts from 607 biopsies, and applied receiver-operating characteristic (ROC)-curve analysis. From that perspective, it appears that counting IEL/100 enterocyte nuclei in routine haematoxylin and eosin (H&E) sections provides the most useful discriminator of celiac mucosae at histological level, with an effective cut-off of 27 IEL, and offering a very high sensitivity with few false negatives. ROC-curve analysis also revealed the somewhat lesser accuracies of either CD3+ or γδ+ IEL counts. Current official guidelines seem to be somewhat inadequate in clearly defining the spectrum of gluten-induced mucosal pathologies and how they could be optimally interpreted, as well as in promoting the ideal manner for physicians and pathologists to interact in interpreting intestinal mucosae submitted for analysis. Future trends should incorporate 3-D printing and computerised modelling in order to exemplify the subtle micro-anatomical features associated with the crypt-villus interzone. The latter needs precise delineation with use of mRNA in-section assays for brush border enzymes such as alkaline phosphate and esterase. Other additional approaches are needed to facilitate recognition and interpretation of the features of this important inter-zone, such as wells, basins and hypertrophic alterations in the size of inter-villous ridges. The 3-D computerised models could considerably expand our understandings of the microvasculature and its changes—in relation both to crypt hypertrophy, in addition to the partial attrition and subsequent regrowth of villi from the inter-villous ridges during the flattening and recovery processes, respectively.

Abstract
The association of epilepsy, occipital calcifications, and celiac disease has been recognized as a distinct syndrome. The objective of this study was to present the clinical, electrophysiologic, and neuroradiologic features in a series of patients with this syndrome. Thirty-two patients with the constellation of epilepsy, occipital calcifications, and celiac disease were identified in our epilepsy clinic. The mean age was 11 years and the mean length of follow-up was 7.4 years. The 1990 criteria of the European Society of Pediatric Gastroenterology and Nutrition were used to diagnose celiac disease. The Kruskal-Wallis statistics test was employed with a signficance of P < .05. Thirty-one patients had partial seizures, 21 of them with symptoms related to the occipital lobe. In most patients, the epilepsy was controlled or the seizures were sporadic. Three developed severe epilepsy. Occipital calcifications were present in all cases. Computed tomography in 7 patients showed hypodense areas in the white matter around calcifications, which decreased or disappeared after a period of gluten-free diet in 3 patients. A favorable outcome of epilepsy was detected in patients with the earliest dietary therapy. This study presents the largest series of children with this syndrome outside Italy. White-matter hypodensities surrounding calcifications are rarely reported. A prompt diagnosis of celiac disease might improve the evolution of the epilepsy and may improve cognitive status.

Abstract
To further define intraepithelial lymphocytes (IELs) in celiac disease (CD) and giardiasis, IELs were probed for the presence of cytolytic granules containing granzyme B (GrB) and T-cell-restricted intracellular antigen (TIA)-1. The expression of TIA-1, GrB, CD3 (T-cell-receptor-associated complex), and Leu-7 (subset of natural killer cells) was studied by a sensitive three-step immunoperoxidase technique. Stained IELs were determined quantitatively, and results were expressed as number of stained IELs per 100 epithelial cells (ECs). The relative content in labeled lamina propria lymphocytes was determined and expressed as the percentage of all lamina propria cells counted. When compared with controls, CD3+ and GrB+ IELs were significantly increased (P < 0.0004) in CD paralleled by an increase in TIA-1+ IELs (P < 0.0004). In CD, the highest numbers of IELs containing GrB were found in subjects with a flat mucosa (median, 38 IELs/100 ECs, P < 0.0004), followed by cases with shortened and blunted villi (median, 8 IELs/100 ECs, P < 0.0004) and, finally, CD patients with an intact villous architecture (median, 0.5 IELs/100 ECs, P < 0.02). Except for cases with giardiasis, Leu-7+ IELs were virtually absent in all groups as were GrB+ IELs in the controls and in subjects with giardiasis. In the lamina propria of CD subjects, GrB+ lymphocytes were also significantly increased (P < 0.001), whereas controls and cases with giardiasis were essentially free of GrB+ cytotoxic T lymphocytes. The percentage of CD3+ lamina propria lymphocytes was nearly equal in all groups. In humans and mice, extensive studies revealed a GrB expression to be absolutely restricted to activated cytotoxic T lymphocytes and natural killer cells. TIA-1, on the other hand, is considered a marker of resting T lymphocytes possessing cytolytic potential. We therefore conclude that IELs are cytotoxic T cells that are in a resting state in the normal small bowel and in giardiasis. In CD, they become activated as suggested by the GrB positivity of their granules.

Abstract
Gluten sensitivity is associated with a spectrum of mucosal lesions, arbitrarily termed pre-infiltrative, infiltrative-hyperplastic, flat-destructive and atrophic-hypoplastic. Histologically and immunohistologically these lesions are all compatible with T-cell-driven events operative at a local mucosal level. They are classifiable either in terms of antibody titres (pre-infiltrative) (see Chapter 10) or by the characteristic disposition of IELs throughout the surface and crypt epithelium. From in-vivo challenges, it has been demonstrated: (i) that all these lesions comprise a dynamically interrelated series of events, culminating in the severe flat-destructive lesion; and (ii) that gluten evokes a dose-responsive infiltration of IELs (CD3+ CD8+ and TCR alpha beta + or gamma delta +) into the epithelium. Apart from that, little is known of the functions of IELs; it is possible they may have little to do with the evolving mucosal pathology of gluten sensitivity. Increasing work seems to support a view, proposed from this laboratory over 10 years ago, that the immune-mediated responses in jejunal tissue in gluten sensitivity arise in the lamina propria, in association with DR+ macrophages and an abundance of CD4(+)-activated lymphocytes. Many other inflammatory consequences flow from these interactions, involving activation of mast cells, eosinophils and neutrophils, elaboration of cytokines and other products of inflammation, and increased hyperpermeability of the microvasculature with upregulation of adhesion molecules. The result is a doubling of lamina propria volumes in the severe flat lesion. Evidence is also given to show that measurable changes in lamina propria inflammation occur with the infiltrative-hyperplastic lesion. Symptomatology is not related to the degree of proximal mucosal pathology, but to the extent of the mucosal lesion. Data, although scanty, suggests that lesional pathology involves only 30-50% of the entire small bowel mucosa. Thus, most patients, irrespective of proximal mucosal damage, have latent (or asymptomatic) gluten sensitivity. Symptom development requires additional environmental triggers, of which infection is a major contributor. It should also be noted that, while these various environmental triggers may precipitate symptomatology, they do not advance the severity of the mucosal lesion.

Abstract
The intestine is largely colonized by bacteria and further exposed to an immense array of ingested and shed immunogenic material. Therefore, the gut associated lymphoid tissue plays a major role in the human immune system. It may even constitute a unique immune system of its own, since it has been demonstrated to differ anatomically, phenotypically, functionally and on a molecular basis from its systemic counterpart and other peripheral lymphoid tissue. This is ultimately reflected by the observation in (transgenic) mice that intraepithelial T cells can develop independently of the thymus. Along the same lines, a rapidly growing body of evidences suggests that human bone marrow precursors can home to the gut epithelium, rearrange their T cell receptor genes and further differentiate in the mucosal micro environment. This, and other features that characterize the 'diffuse' mucosal T cell infiltrate will be discussed.

Abstract
OBJECTIVES To study the different forms of malignant lymphoma complicating coeliac disease in a low-prevalence area, according to extranodal-nodal and extraintestinal-intestinal manifestations. SUBJECTS AND SETTING Patients recruited from two University Hospitals (Amsterdam, Leiden) and from PALGA (National Dutch data-bank) over a 16-year period. DESIGN Review of hospital charts with respect to clinical presentation and treatment of both coeliac disease and malignant lymphoma. Re-evaluation of morphology and staging by immunoperoxidase, enzyme- and immunohistochemical stainings on unstained and frozen materials. MAIN OUTCOME MEASURES Clinical behaviour and T- or B-cell morphology of extranodal intestinal, extranodal extraintestinal and nodal intestinal disease. RESULTS Fourteen cases of enteropathy-associated lymphoma could be traced, 10 with a history of coeliac disease, four primarily presenting with malignant lymphoma. The usual extranodal intestinal lymphoma (eight cases) presented with abdominal pain, weight loss, and malabsorption. Six had atypical disease: four presented with extranodal extraintestinal disease, located in the skin or the respiratory tract; two patients had intractable malabsorption and oedema caused by a nodal intestinal lymphoma. Re-evaluation with additional immunohistochemical stainings in 11 patients showed a pleomorphic malignant infiltrate of histiocyte-like cells of T-cell origin, with a pattern of CD3+; CD4-; CD5 +/-; CD7+ and CD8-. It also established a more appropriate diagnosis in four, an 0.6-year earlier diagnosis in six, and an upgraded stage of disease in two patients. A more extensive spread and poorer outcome appeared to become more probable in the ranking order of extranodal intestinal, extranodal extraintestinal and nodal intestinal lymphoma. CONCLUSIONS A proper and timely diagnosis of enteropathy-associated lymphoma requires clinical vigilance and unrelentless perseverance to obtain adequate fresh and frozen tissue for histochemical staining. Further research in a larger number of patients is warranted to investigate the relation between the primary site of the lymphoma, i.e. extranodal intestinal, extranodal extraintestinal, or nodal intestinal, and (its impact on) clinical presentation and prognosis.

Abstract
Gamma/delta T cells are increased in the gut epithelium of patients with coeliac disease compared with normal controls. The aim of this study was to determine whether the increase in gamma delta intraepithelial lymphocytes (IEL) is specific for coeliac disease, in which case it could be of diagnostic importance. Biopsies were obtained from children with no intestinal disease, coeliac disease, cow-milk-sensitive enteropathy/post-enteritis syndrome (CMSE PES) and miscellaneous other enteropathies (n = 67). Intraepithelial CD3+ and gamma delta T cells were identified in frozen sections using peroxidase immunohistochemistry. In normal biopsies there were 0-7 gamma delta IEL/100 cells in the epithelium. In untreated coeliac patients this increased to 9-22 gamma delta IEL/100 cells in the epithelium (P = 0.000004). Of 27 patients with morphologic intestinal damage which was not due to coeliac disease, four with CMSE/PES had gamma delta IEL/100 cells in the epithelium in the same range as the patients with coeliac disease. Of these, two had high densities of CD3+ IEL in the epithelium and were indistinguishable from patients with untreated coeliac disease. The other two could be excluded as possible coeliacs because their CD3+ IEL/100 epithelial cells were in the normal range. Thus an increase in gamma delta IEL is not specific for coeliac disease. However, enumeration of both of gamma delta IEL and CD3+ IEL densities will be useful in the exclusion of coeliac disease as a diagnosis in some children.

Abstract
Fifty two first degree relatives of patients with coeliac disease were investigated for HLA status, small intestinal permeability, and mucosal morphology together with the size of the intraepithelial lymphocyte pool and indices of lymphocyte activation, in an attempt to identify genetically determined markers of the disease. Thirty eight per cent of these subjects had increased intraepithelial lymphocyte populations and a highly significant association with HLA-DR3 compared with controls. Their intestinal permeability to 51chromium-labelled ethylenediamine tetraacetate was invariably normal and there was no evidence of abnormal mucosal architecture, increased crypt cell mitotic activity or lymphocyte 'activation'. Although increased intraepithelial lymphocyte counts clearly do not cause alterations in intestinal structure or function, it is likely that this parameter together with the HLA-DR3 status identifies a genetically determined predisposition to the disease which may only become clinically evident with larger doses of ingested gluten.

Abstract
The immunopathologic, structural, and functional changes within rectal mucosa of known celiac sprue subjects were quantitated during local challenge with a peptic-tryptic digest of gluten. In the celiac sprue patients challenged with 2 g of digest, major effects occurred in lamina propria, submucosa, and local microvasculature. The lamina propria swelling was biphasic, starting 1-2 h after challenge with widespread extravascular deposition of fibrinogen, indicative of increased microvascular permeability, receding by 24 h postchallenge. A rapid fall in mast cells together with granule discharge suggested their involvement in this response. The late-phase swelling (48-72 h) was preceded by a rapid influx of neutrophils and basophils, the latter showing evidence of degranulation beyond 72 h. Reestablishment of vessel lumina, a rise in mast cells, and loss of neutrophils indicated tapering of the inflammatory cellular cascade by 96 h. Lymphocytes, first seen to enter the lamina by 2 h postchallenge, increased progressively, thereby resulting in substantial infiltration between 36 and 96 h. A marked rise in epithelial lymphocytes, maximal at 6-8 h, waned by 24 h. Volumes of surface and crypt epithelium remained constant throughout. In another challenge series with 4 g of gluten digest, electrical potential difference across rectal mucosa decreased significantly 12 h postchallenge, but the associated decreases in net sodium and chloride absorptive fluxes were insignificant. It is concluded that rectal mucosa is sensitized to gluten in celiac sprue disease and thus offers a promising and convenient in vivo substrate for investigative and diagnostic purposes.

Abstract
Peroral jejunal mucosae from 32 patients with untreated DH were quantitated by computerized image-analysis in terms of surface (villous) and crypt epithelial volumes and their corresponding lymphoid infiltrates, together with lamina propria volumes, neutrophils, mast cells and basophils. Three distinctive patterns of mucosal abnormality were identified: (a) the "infiltrative" lesion in which normal villus epithelium was infiltrated by small, non-mitotic lymphocytes: (b) the "hyperplastic" type, in which crypt hyperplasia and hypertrophy together with lymphoid infiltration of crypt epithelium was additional to the "infiltrative" lesion, and in which lamina propria was swollen and contained modest neutrophilic and basophilic infiltration: and (c) the "destructive" lesion, identical to the classic celiac sprue appearances with effacement of villi, crypt hypertrophy and more intensive polymorph infiltration of lamina propria. These progressive lesions parallel those seen in experimental graft-versus-host reactions, so that the entire spectrum of changes described here in DH appear consistent with a cell-mediated mucosal response to gluten. The extent of mucosal abnormality was unrelated to individual HLA status.

Abstract
Computerised image-analysis was used to define the spectrum of immunopathological changes in small intestinal mucosa in established celiac sprue disease; dermatitis herpetiformis; 1 degree relatives of celiac sprue patients, and treated celiac sprue patients challenged with varying doses of a peptic-tryptic digest of gluten. Typically, in flat ('Type 2') lesion there was a reduced number of large, mitotically active lymphocytes in surface epithelium, but an increased lymphocyte population in crypts. In approximately 50% untreated DH patients and in 20% 1 degree celiac sprue relatives, mucosal architecture was well-preserved although surface (villous) epithelium contained an expanded population of small, non-mitotic lymphocytes ('Type 1' lesion), with or without crypt hyperplasia. Similar changes were also induced by small dose gluten challenge. Larger dose challenges caused a progression from a Type 1 to a Type 2 lesion during a 5 day period of observation. In addition, observations on a few patients over 2-4 years showed a similar sequence of mucosal changes. A major feature of this sequence was the early appearance of crypt hypertrophy, before significant villous flattening had occurred. These changes parallel T lymphocyte-mediated graft- versus-host reactions in animals, suggesting that the specific immunopathologic features seen in gluten sensitivity are fundamentally cell-mediated in type, the degree of change probably dependent on host genetic factors. Finally, these data show that in becoming flat the mucosa must initially pass through the earlier Type 1 lesion in which crypt hypertrophy is a prominent response.

Abstract
A proportion of epithelial lymphocytes in various mammalian species is characterised by cells containing cytoplasmic granules. We have studied the total number of granular lymphocytes within surface and crypt epithelium of jejunal mucosae (per 10(4) micron2 muscularis mucosae) from six groups of subjects, comprising (i) young healthy volunteers (ii) family relatives of known coeliac patients, patients with gastrointestinal disorders associated with either (iii) normal or (iv) "flat" mucosae, and groups of (v) untreated and (vi) treated patients with coeliac disease. There was no difference in the absolute number of gEL between the three control groups with normal mucosal architecture, the proportion of granular to total EL per unit of tissue varying between 30-40%. In untreated coeliac mucosae, there was a significantly increased population of gEL, compared with the same control groups (p less than 0.001): the ratio of granular to total EL approximated 65%, and did not differ from flat-control mucosae in which the proportion of gEL was 55%. On withdrawal of gluten, the absolute number of gEL fell significantly in comparison with the untreated coeliac group (p less than 0.05). To further evaluate the effect of gluten challenge, granular lymphocytes were monitored during a five-day period in groups of treated coeliac patients orally challenged with increasing doses (500-3000 mg) of a peptic-tryptic digest of gluten. A significant rise in the absolute number of granular lymphocytes occurred at 12 h, but without any deterioration in mucosal architecture.

Abstract
Abnormalities of gut endocrine responses, as well as changes in the number of different endocrine cell types, have been reported convincingly in coeliac patients. Nevertheless, no estimation of total numbers of gut endocrine cells has yet been made in well defined groups of coeliacs. In this study, we have visualised all endocrine cell types in jejunal biopsies from coeliac patients with active and quiescent disease as well as in controls, using a monoclonal antibody to chromogranin. This protein was purified originally from bovine adrenal medulla and is known to be a reliable marker for all endocrine cells of the gut. The following groups were considered: (a) nine coeliacs with active illness, (b) 10 coeliacs under gluten-free diet, (c) eight coeliacs receiving gluten challenge, (d) five non-coeliacs (controls). Histological (haematoxylin and eosin) and immunocytochemical (peroxidase anti-peroxidase) stains were applied to 3 micron paraffin sections. Quantitative estimation of endocrine cell density was made using four different methods in order to evaluate the results fully (number of cells/mm2, number of cells/visual field, number of cells/8 crypts-villi, number of cells/unit of length of muscularis mucosae). In patient groups (a) and (c), coeliacs with active disease and coeliacs on gluten challenge diet respectively, a significantly higher number of endocrine cells was observed in comparison with normal controls (group d). In group (b) patients, coeliacs on gluten-free diet, no significant changes in the number of endocrine cells were observed in comparison with controls. Our results show that a significant increase in endocrine cell density exists in coeliacs with active illness (groups a and c), in comparison with controls. This condition is resolved in coeliacs receiving a gluten-free diet (group b).

Abstract
When there is villus atrophy in a jejunal biopsy, intraepithelial lymphocyte (IEL) mitosis correlates with a diagnosis of coeliac disease. We have examined the significance of IEL mitosis in jejunal biopsies with normal villi. Counts of IEL per 100 villus enterocytes, and IEL mitosis per 1000 IEL, were carried out in 81 jejunal biopsies. Thirty one were from patients with coeliac disease or dermatitis herpetiformis, and many of these, from treated patients, were histologically normal; 40 were from patients with other diagnoses, selected to include biopsies with a high IEL count (greater than 40 IEL per 100 enterocytes) but normal villi. Three coeliacs and 10 dermatitis herpetiformis patients had an IEL count of less than 40, and no IEL mitoses were found in these biopsies. Two dermatitis herpetiformis patients had IEL counts of 43.7% and 43.9%, with no IEL mitoses, but in all other coeliac and dermatitis herpetiformis biopsies high IEL counts were associated with IEL mitotic indices between 0.05% and 1.77%. In the non-coeliac, non-dermatitis herpetiformis group, no IEL mitoses were found in the 22 biopsies with IEL count less than 43%. In the others, IEL counts ranged from 44.8% to 127.0%, and IEL mitoses were present, with mitotic indices ranging from 0.06% to 0.49%. This work shows that IEL mitosis in a jejunal biopsy is not specific for coeliac disease, but occurs whenever there is an increased density of IEL within the villus epithelium.

Abstract
With the aid of computerised image-analysis, morphometric techniques were used to measure the volumes of crypt epithelium, with reference to a constant test area (10(4) microns2) of muscularis mucosae, in untreated and treated celiac sprue mucosae in comparison with four other groups of control jejunal specimens. Crypt epithelial lymphocyte populations were also analyzed in terms of absolute numbers (N), mean nuclear (DN) and cytoplasmic (DCYT) diameters, and mean nuclear (VN) and cell (VCELL) volumes. Untreated celiac sprue crypts, despite a 3-5 fold increase in volume over control mucosae, contained a markedly expanded population of lymphocytes which was localised predominantly to the upper crypt regions and comprised approximately 6% large lymphocytes (DN greater than 6 microns: DCYT greater than 9 micron). These changes were entirely reversed by dietary treatment and hence were considered to be gluten-driven. The infiltrate might reflect the expression of gluten receptors on maturing upper crypt enterocytes: but why these lymphocytes do not cause any apparent injury to crypt epithelium (unlike surface epithelium) or influence its well-known compensatory response, remains unclear.

Abstract
Jejunal biopsy specimens from coeliac patients who had received small, oral doses (100-1500 mg) of a peptic-tryptic gluten digest were analysed by morphometric methods. An increase in the total number of surface epithelial lymphocytes, maximal at 12 h after challenge, was dose-dependent, the mean percentage rise at this time being 53% (p less than 0.005), 44% (p = 0.01), and 25% (p greater than 0.05) with 1500, 1000, and 500 mg of gluten digest, respectively. This effect was not accompanied by any increased mitotic activity or blast transformation among the infiltrating lymphocytes, nor was there any demonstrable alteration in mucosal structure-that is, reduction in surface or increase in crypt epithelial volumes. The results of this controlled morphometric analysis indicate that oral gluten challenge causes an increase in the lymphocyte population of surface epithelium in coeliac disease but that this effect does not necessarily result in mucosal damage.

Abstract
To study mast cell, basophil, and eosinophil populations within celiac sprue mucosae in comparison with various disease-control specimens, toluidine blue-stained 1-micron plastic sections were analyzed morphometrically by light microscopy. Within lamina propria of celiac sprue mucosae each population of cells was markedly expanded and fell to control levels during gluten restriction. Changes within surface and crypt epithelium, however, were not significantly different from those in the severer, "flat" disease-control lesions, and were not affected by gluten restriction. Basophils were not identified within surface or crypt epithelium of any specimen analyzed. The influx of eosinophils and basophils into lamina propria occurred by emigration via pericryptal venules. Mature mast cells were not seen within the microvasculature, neither were these cells undergoing mitosis: thus their origin was from unidentified precursors. The gluten-dependent alterations in each of these cell populations in celiac sprue mucosae are consistent with secondary effector mechanisms, probably resulting from cell-mediated reactions that occur primarily within the lamina propria, rather than the epithelium.

Abstract
Epithelial lymphocytes comprise a compartmentalised and specialised population of presumed effector cells which, in general, express the surface phenotypes (Lyt-2+; OX2+; OKT8+) of suppressor/cytolytic (Ts/c) cells. Granular cells within this population (gEL) morphologically resemble the circulating large granular lymphocytes (LGL) which subserve spontaneous (NK) cytolytic activity. Recent in vitro results indicate that gEL can develop this function after prolonged in vitro culture; the relevance of this, in vivo, remains to be decided. EL also appear to be able to mediate ADCC with sIgA against enteric micro-organisms. This is the kind of integrated activity that might be anticipated from local immunocytes within the intestinal mucosa. Other recent work suggests that gEL are not precursors of mucosal mast cells. EL also appear to be capable of inducing Ia-like expression in surface and crypt enterocytes, a property enjoyed both by highly purified Th, but also Ts/c, cells as well. This raises the interesting prospect that enterocytes may display antigen in macrophage-like fashion to other adjacent cells within the inter-epithelial cell spaces. These latter observations might be more consistent with the presence of 'activated' and 'blast-transformed' lymphocytes in such conditions as coeliac disease and tropical sprue. Another emergent view that demands appropriate attention is that the infiltrate of Ts/c cells into surface, and crypt, epithelium of coeliac mucosa does not necessarily cause injury or damage to the jejunal tissues. Nevertheless the role, either primary or secondary, that EL play either in coeliac disease or tropical sprue still remains obscure.

Abstract
Morphometric techniques were employed to measure (i) lamina propria volumes and (ii) the absolute numbers of neutrophils and plasma cells, of A, M and G isotype, within the lamina propria of jejunal mucosa. Mucosal specimens were obtained with a Watson capsule (a) from 5 patients with untreated coeliac disease, and again at least 3 months after starting on a gluten-free diet, and (b) from 9 control individuals. Lamina propria volume of untreated coeliac mucosa (2.5 +/- 0.17 X 10(6) micron3 ) was increased 2.3-fold (p less than 0.01) above that of control mucosae (1.35 +/- 0.08 X 10(6) micron3 ). Compared with control mucosae, there was a 20-fold increase of neutrophils in untreated coeliac mucosae (p less than 0.005). The total complement of all plasma cells in untreated coeliac mucosae (309) was twice that (149) of control mucosae. The populations of each isotype were also significantly increased over controls by factors of 1.6 (IgA; p less than 0.05), 3.0 (IgM; p less than 0.01) and 3.5 (IgG; p less than 0.01). Their percentage distributions in untreated coeliac mucosae (A:M:G--52:43:5) differed from those in control mucosae (A:M:G--69:28:3) but were restored after treatment with a gluten-free diet. However, when each isotype was expressed per unit volume of lamina propria, there was an apparent fall (X 1.4) in IgA cells, while the increase in IgM and IgG cells was less marked i.e. X 1.4 and X 1.5 respectively. These precise measurements explain why many previous investigators found a paradoxical fall in IgA cells because the (increased) volume of distribution of these cells was not taken into account. The importance of morphometric techniques in achieving valid cell 'counts' within the intestinal mucosa is thus illustrated by this study.

Abstract
Morphometric techniques were used in the evaluation of lymphocyte morphology and activity in tropical sprue. jejunal biopsies from control subjects (8), patients with epidemic disease (7), patients with endemic disease (11), and subjects who had recovered from sprue (4) were analyzed blindly. In patients with sprue, lymphocytes were increased significantly within crypt (but not surface) epithelium. Immunoblasts (greater than 6 mu in diameter) were increased by 5% over control subjects. Group means for lymphocytic mitotic indexes were also significantly raised, while flux ratios only differed significantly between endemic sprue patients and control subjects. The lymphocytic infiltration was distributed focally in the upper crypt and crypt-villus interzones. Analysis of epidemic cases (presenting within 4-28 days) revealed detectable changes in lymphocyte behavior only after 3 weeks' illness, whereas mucosal lesions and malabsorption were already established during the first week. These data indicate that lymphocyte activation, suggestive of a local cell-mediated immune reaction, does occur in tropical sprue but is secondary to damage already inflicted on enterocytes and their function.

Abstract
Several diseases of the small intestine, including gluten-sensitivity, present with malabsorption and a "flat" mucosa. Determination of the mitotic index of epithelial lymphocytes provides a simple, objective method of assessing, and thus of predicting, whether a flat mucosa is due to gluten-sensitivity (index greater than 0.2%), or not (index less than 0.2%). The use of this index in circumstances especially likely to cause diagnostic confusion--for example, intestinal lymphoma; Crohn's jejunitis of immunodeficiency--is illustrated in this paper. Of seven cases, five (two primary lymphoma, three immunodeficiency) had been treated with a gluten-free diet without benefit; a mitotic index performed on the initial biopsy in each of these patients could have predicted from the outset that none was gluten-sensitive. Of the remaining two cases, determination of the mitotic index on the biopsy initially obtained from a man with severe hypogammaglobulinaemia would have indicated that he was also gluten-sensitive. Empirical use of a gluten-free diet was avoided in the other patient (with flat small intestinal mucosa and low mitotic index) in whom the diagnosis was ultimately shown to be due to Crohn's disease of jejunum.

Abstract
We present a case of a 33 year old male with a history of early childhood diarrhoea and more recently diagnosed gluten sensitive enteropathy, who died with active disease, ulcerative proctosigmoiditis and desquamative erythrodermia associated with toxin induced shock. Autopsy revealed a tumour restricted to lymph nodes of the mesentery and the retroperitoneum. This is considered to be malignant histiocytosis of the intestine (MIH). Immunohistological examination of the diagnostic jejunal biopsy showed a pathological binding pattern for peanut lectin (PNL) within the enterocytes. This may be an expression of disturbed production or secretion of a product rich in non-reducing terminal D-galactosyl residues.
