Enterocolic lymphocytic phlebitis with lymphocytic colitis, lymphocytic appendicitis, and lymphocytic enteritis.

We describe a 53-year-old man with a history of diarrhea temporally related to the use of flutamide. He developed an acute abdomen, and presented with an ileocecal intussusception due to an edematous ischemic cecum. The ischemia was due to enterocolic lymphocytic phlebitis (ELP), with numerous associated thrombi. The phlebitis involved not only the ischemic area but also the grossly unaffected areas, including the entire right colon, terminal ileum, and appendix. All layers of the bowel wall were involved. Mesenteric veins were also prominently affected, but the arteries were spared. This rare form of vasculitis was associated with a marked lymphocytic infiltrate involving the epithelium of the entire right colon, ileum, and appendix. This is the first reported case of ELP occurring in conjunction with lymphocytic colitis, lymphocytic enteritis, and lymphocytic appendicitis. The temporal association of the patient's symptoms with flutamide use suggests that this peculiar form of lymphocytic inflammation of the veins and mucosa likely represents a drug reaction. We suggest that some cases of lymphocytic colitis may also be associated with ELP but are unlikely to be recognized unless affected submucosal vessels happen to be included in the biopsy.

Collagenous colitis and lymphocytic colitis: patient characteristics and clinical presentation.

OBJECTIVE: Collagenous colitis and lymphocytic colitis (collectively known as microscopic colitis) are characterized by chronic diarrhea, normal endoscopic and radiologic findings, and typical findings on histologic examination of colonic tissue. The purpose of this study was to define the background characteristics of patients with microscopic colitis, as well as to present symptoms, coexistent autoimmune diseases, and a possible association with the use of non-steroidal anti-inflammatory drugs (NSAIDs) and ticlopidine. MATERIAL AND METHODS: A retrospective chart review was carried out on all cases of collagenous colitis and lymphocytic colitis diagnosed at a single center from July 1992 to July 2002. RESULTS: Of the 104 patients identified, 66 had collagenous colitis, 35 had lymphocytic colitis, and 3 were diagnosed with both disorders at different times. The mean age of patients was 64 years (26-88 years), with a female:male ratio of 4.8:1. The most common presenting symptoms were diarrhea (95%), weight loss (41%), abdominal pain (40%), fecal urgency (29%), and nocturnal stools (22%). Autoimmune disease was diagnosed in 29% of patients, 35% were using an NSAID, and 2% were using ticlopidine. CONCLUSIONS: Collagenous colitis and lymphocytic colitis occur more often in females than in males, at a wide age range, with a mean in the seventh decade. Certain symptoms are characteristic, but are not specific to these disorders. There may be an association with the presence of a coexistent autoimmune disorder and the use of drugs such as NSAIDs.

[Simultaneous occurrence of lymphocytic gastritis and lymphocytic colitis with transition to collagenous colitis].

Lymphocytic gastritis and lymphocytic colitis are two rare disorders of unknown etiology, only diagnosable by histology. Simultaneous occurrence of lymphocytic colitis and lymphocytic gastritis has not been described up to now. A 69-year-old female patient was examined because of crampy abdominal pain and watery diarrhea. Laboratory tests did not reveal an etiology and in colonoscopy the colon and terminal ileum were normal. Histology disclosed lymphocytic colitis. Esophagogastroduodenoscopy showed erosive bulbitis. Biopsies of the stomach revealed lymphocytic gastritis. A second colonoscopy one year later showed the development of collagenous colitis.

Increased HLA A1 and diminished HLA A3 in lymphocytic colitis compared to controls and patients with collagenous colitis.

Lymphocytic colitis is a newly described chronic diarrheal disorder. Although its etiology is unknown, the possibility has been raised that autoimmunity may play a role in both lymphocytic and collagenous colitis, a similar clinicopathologic illness. The frequencies of HLA class I and class II antigens were examined in 24 white patients with lymphocytic colitis and in 47 white patients with collagenous colitis. Frequencies in these two disorders were compared to control white populations and to each other. An increased frequency of HLA-A1 was noted in 16 of 24 lymphocytic colitis patients (66.6%) compared with 1089 of 3942 controls (27.6%) (P less than 0.005; relative risk 5.2). Furthermore, HLA-A3 was found in decreased frequency in lymphocytic colitis patients: 0 of 24 (0%) compared with 1017 of 3942 controls (25.8%) (P less than 0.05; relative risk 0.0). Collagenous colitis patients had no significant deviation from control frequencies of HLA antigens. In lymphocytic colitis, there was no significant increase in B8 or DR3 antigens, which are found in linkage disequilibrium with A1 and associated with many autoimmune diseases. Moreover, the frequency of autoimmune-associated class I HLA antigens was not increased in lymphocytic colitis. Statistically significant differences existed between lymphocytic and collagenous colitis in HLA-A1, A3, Bw6, and B7 antigen frequencies. The HLA patterns noted previously in other gastrointestinal disorders, including ulcerative colitis and Crohn's disease, were not apparent in lymphocytic or collagenous colitis. HLA typing provides further evidence that lymphocytic colitis is a distinct form of chronic intestinal inflammatory disease associated with HLA class I phenotypes.

[Ticlopidine-induced lymphocytic colitis].

Lymphocytic colitis is a clinico-pathological syndrome characterized by chronic diarrhea, normal endoscopy, diffuse colonic mucosal inflammatory changes. Collagenous colitis is defined by a thickening of the collagen plate. The etiology is unknown but immune disorders have been frequently associated with it and it has been linked with the taking of certain drugs such as nonsteroïd anti-inflammatory drugs or veinotonics. We are reporting a case of microscopic colitis associating both lymphocytic and collagenous colitis, wich induced chronic diarrhea in a 65-year-old man. It appeared after he had taken ticlopidine. Diarrhea stopped after he had discontinuated ticlopidine, and recurred after he resumed taking the drug. Histological damages from lymphocytic colitis improved six month after he had stopped taking ticlopidine. Chronic diarrhea induced by ticlopidine might be caused by lymphocytic colitis.

Failure of added dietary gluten to induce small intestinal histopathological changes in patients with watery diarrhea and lymphocytic colitis.

Lymphocytic colitis is a form of microscopic colitis usually characterized by watery diarrhea and often associated with biopsy-defined celiac disease. Two patients with lymphocytic colitis and normal small intestinal biopsies who were administered 40 g of added dietary gluten for four consecutive weeks are presented. Small intestinal biopsies from multiple sites in the proximal small bowel were done after three and four weeks to determine whether pathological changes in latent celiac disease could be induced in these patients with a high gluten-containing diet. In addition, colorectal biopsies were done to determine whether the colitis was sensitive to oral gluten. No alterations in the small intestinal biopsies were detected in either patient and no changes occurred in colitis severity. Although microscopic forms of colitis have been linked to celiac disease, this study indicates that lymphocytic colitis is a heterogeneous clinicopathological disorder that, in some patients, is independent of any gluten-induced intestinal pathological changes.

Oral budesonide for lymphocytic colitis.

Lymphocytic colitis is a rare inflammatory colonic disease of unknown etiology accompanied by watery diarrhea. Diagnosis is based upon pathological examination of colonic biopsies. Treatment essentially involves antiinflammatory agents such as sulfasalazine/5-ASA or corticosteroids if necessary. We report the case of a female patient suffering from severe lymphocytic colitis who remained unresponsive after 5-ASA therapy but who improved dramatically after oral budesonide administration.

[Chronic diarrhea: a difficult diagnosis. A rare cause: lymphocytic colitis].

Lymphocytic colitis is a clinicopathological entity, characterized by chronic watery diarrhea, not bloody. Previously termed microscopic, it is now named lymphocytic for histological features, the most important seems to be the diffuse infiltration of intraepithelial lymphocytes, that must be investigated in multiple biopsies during colonoscopy. This review evidences that during endoscopy the mucosa is normal, but this does not exclude a biopsy, only way for take a diagnosis. Ethiologies are unknown too although a correlation with autoimmune diseases as possible. Lymphocytic colitis is a definition histological entity, while the term ''microscopic'' includes different histological entities under the same ''umbrella'', in relation to the concept of no macroscopic changes and multiple different histological specimens. The treatment is based for the first time on mesalazine or sulphasalazine and then in case of non responders, on corticosteroids.

Newly recognized forms of colitis: collagenous colitis, microscopic (lymphocytic) colitis, and lymphoid follicular proctitis.

Based on pertinent data from the literature and on their personal experience, the authors present a clinicopathological review of collagenous colitis, microscopic (lymphocytic) colitis, and lymphoid follicular proctitis. The following aspects of these three newly recognized forms of colitis are emphasized: clinical features, light microscopy, histological diagnostic problems, immunological aspects, coexisting diseases, treatment, etiology, and pathogenesis. Special attention is paid to possible overlap between collagenous colitis and microscopic (lymphocytic) colitis.

Collagenous colitis and lymphocytic colitis.

The most recently recognized and least understood forms of inflammatory bowel disease are two types of idiopathic microscopic colitis-collagenous colitis and lymphocytic colitis. These disorders share many clinical and histologic features, but they have a few notable differences. Whether these are two distinct entities or different presentations of the same disease remains controversial. Bismuth subsalicylate is effective in some patients and treatment is symptomatic and empirical in others. Unlike ulcerative colitis and Crohn's disease, these forms of inflammatory bowel disease rarely require surgery. Ileostomy with or without colectomy is curative for the rare patient with severe symptoms that are refractory to medical measures. Collagenous and lymphocytic colitis are not associated with an increased risk of malignancy.

Are collagenous colitis and lymphocytic colitis distinct syndromes?

The term microscopic colitis has largely evolved to be an umbrella term which includes the histopathological entities of lymphocytic colitis and collagenous colitis. The purpose of this review is to compare these two syndromes. Lymphocytic colitis and collagenous colitis are characterized by chronic watery diarrhea, normal radiographic and endoscopic findings, and abnormal colonic mucosa on biopsy with lymphocytic infiltration of the lamina propria but minimal crypt distortion. Collagenous colitis is further characterized by a thickened subepithelial collagen band. Lymphocytic colitis has an equal sex distribution, while collagenous colitis has a marked female predominance. Histocompatibility phenotypes are also dissimilar. These findings suggest that lymphocytic colitis and collagenous colitis may be related but distinct syndromes.

Collagenous colitis and lymphocytic colitis.

Collagenous and lymphocytic colitis are newly recognized causes of chronic watery diarrhea that typically affect middle-aged patients. Although endoscopic studies are normal, inflammatory changes and (in the case of collagenous colitis) collagen deposition occur histologically in the colonic mucosa. The pathogenesis of these disorders remains a mystery, but the possible causes are intriguing. Patients may experience spontaneous remissions and relapses, but treatment with sulfasalazine or prednisone is usually effective for patients with distressing symptoms.

Collagenous colitis and lymphocytic colitis: clinical and endoscopic findings.

OBJECTIVE: collagenous colitis (CC) and lymphocytic colitis (LC) are two entities of unknown cause, characterized by chronic watery diarrhea, grossly normal-appearing colonic mucosa and abnormal histopathological findings in colonic biopsies. The clinical features of the disease are based mainly on case reports or small uncontrolled series. Although normal colonoscopic findings are, as a rule, part of the diagnosis of CC, several cases of macroscopic colitis associated with CC have been reported, and the spectrum of endoscopic mucosal changes has not been described in large series. METHODS: we present a retrospective study of all patients who underwent total colonoscopy and mucosal biopsy in our Endoscopy Unit between 1991 and 1997. Clinical and endoscopic findings in patients diagnosed as having CC or LC were recorded. RESULTS: of 676 patients studied, 398 suffered from chronic diarrhea. Collagenous colitis was diagnosed in 22 patients and LC in 10. Eleven per cent of the patients with CC and 20% of those with LC did not have diarrhea. Macroscopic colitis was observed in 6 out of 22 patients with CC (27%) and in 4 out of 10 with LC (40%). Macroscopic lesions included edema, erythema, abnormal vascular pattern, superficial erosions or ulcerations and hemorrhagic lacerations. In this series 7.03% of the patients with chronic diarrhea were diagnosed as having CC or LC. CONCLUSIONS: collagenous colitis and LC are two entities that should be considered in the differential diagnosis of chronic diarrhea. Total colonoscopy with multiple biopsies that include the right colon are mandatory. The presence of macroscopic lesions on endoscopy does not rule out a diagnosis of either entity. We identified patients who fulfilled the histopathological criteria for CC or LC but who did not have diarrhea.

Microscopic colitis syndrome: lymphocytic colitis and collagenous colitis.

Microscopic colitis is a syndrome consisting of chronic watery diarrhea, a normal or near-normal gross appearance of the colonic lining, and a specific histological picture described as either lymphocytic colitis or collagenous colitis. Since its initial descriptions a quarter of a century ago, microscopic colitis has become a frequent diagnosis in patients with chronic diarrhea. Understanding of the cause and pathogenesis of microscopic colitis remain incomplete, but potentially important clues have been discovered that shed light on predisposing factors. In particular, specific HLA-DQ genotypes may be permissive for the development of microscopic colitis, and suggest a linkage to the pathogenesis of celiac sprue. Although the differential diagnosis of chronic watery diarrhea is broad, the diagnosis of microscopic colitis is straightforward, involving endoscopic inspection of the colonic mucosa and proper pathologic interpretation of biopsy specimens. As the limitations of drugs ordinarily used for other forms of inflammatory bowel disease are being recognized, new approaches, such as the use of bismuth subsalicylate, are being evaluated. The prognosis of patients with microscopic colitis syndrome remains good, and symptomatic improvement can be expected in most patients.

Paucicellular and asymptomatic lymphocytic colitis: expanding the clinicopathologic spectrum of lymphocytic colitis.

We examined clinicopathologic associations and biopsy changes that suggested classic lymphocytic colitis (C-LC) but were less well developed in intensity or distribution in 19 cases, which we termed paucicellular LC (P-LC). We also studied clinicopathologic associations and prevalence of LC in 100 asymptomatic, non-gluten-sensitive adults who underwent screening surveillance colonoscopy for previous adenoma. The control group was 38 randomly selected morphologically C-LC cases. The features of P-LC were foci of mildly increased lamina propria lymphoplasmacytic inflammation and increased surface intraepithelial lymphocytes separated by foci or tissue fragments of normal mucosa. Mean age and rates of female sex, endoscopically normal appearing colon, abdominal pain, watery stools, weight loss, connective tissue diseases, and consistent ingestion of nonsteroidal anti-inflammatory drugs (NSAIDs) were similar for P-LC and C-LC patients. Of 100 asymptomatic patients, 26 (26%) had LC and 43 (43%) used NSAIDs daily. Of these 43 patients, 14 (33%) had P-LC or C-LC. Daily NSAID ingestion was associated significantly with LC (P = .024). P-LC patients had clinicopathologic relationships similar to those of C-LC patients, suggesting they should be considered part of the morphologic spectrum of LC. LC in asymptomatic adults might be more common than previously thought and might not be associated with watery diarrhea syndrome.
