Ulcerative colitis is a chronic idiopathic inflammatory bowel disease with a relapsing nature. It is a very challenging disease affecting a patient during the most active period of his life i.e. 20 to 40 years of age. The main features are ano-rectal bleeding with increased frequency of bowel evacuation, general debility and with abnormal structural pathology in the descending colon, particularly sigmoid colon. In modern medical science, there is no permanent curative and safe treatment for this disease. This study can be helpful for reducing the need of steroids and surgical processes in the patients of ulcerative colitis. A clinical study of 43 patients of ulcerative colitis has been conducted at the O.P.D. (outdoor patient department) and I.P.D. (indoor patient department) of the P D Patel Ayurveda Hospital, Nadiad. They were given Udumbara kvatha basti with oral Ayurveda medicaments including Kutaj ghan vati, Udumbara kvatha, and combination of Musta, Nagakesara, Lodhra, Mukta panchamrut rasa for a one-month period. Results were analyzed statistically by using the ‘t’ test. In this study, it was observed that the symptoms and signs, daily dose of steroids and other anti-inflammatory drugs were reduced by more than 75% with a highly significant result. The hemoglobin level was also increased.

Background. The thrombosis risk is increased in active ulcerative colitis. The limited number of reported complications have predominantly been cerebrovascular but other vessel territories may also be affected. Patient. During a severe attack of ulcerative colitis a 37-year-old woman suffered occlusion of all left coronary artery branches. Serial angiographies showed progressive recanalisation of the coronary arteries during anticoagulation, but no atherosclerotic stenosis. The cause of infarction was thus considered to be an extensive coronary thrombosis. However, a large battery of blood tests failed to identify any procoagulant abnormality. Conclusion. Evidence is now accumulating that the increased thrombosis risk also may involve the coronary arteries, even in young patients. To the best of our knowledge this is the third reported case of myocardial infarction despite angiographically normal coronary arteries in a patient with active ulcerative colitis. The extent of affected myocardium was in this case exceptionally large.

Recently introduced in the treatment algorithms and guidelines for the treatment of ulcerative colitis, biological therapy is an effective treatment option for patients with an acute severe flare not responsive to conventional treatments and for patients with steroid dependent disease. The reduction in hospitalization and surgical intervention for patients affected by ulcerative colitis after the introduction of biologic treatment remains to be proven. Furthermore, these agents seem to be associated with increase in cost of treatment and risk for serious postoperative complications. Restorative proctocolectomy with ileal pouch-anal anastomosis is the surgical treatment of choice in ulcerative colitis patients. Surgery is traditionally recommended as salvage therapy when medical management fails, and, despite advances in medical therapy, colectomy rates remain unchanged between 20% and 30%. To overcome the reported increase in postoperative complications in patients on biologic therapies, several surgical strategies have been developed to maintain long-term pouch failure rate around 10%, as previously reported. Surgical staging along with the development of minimally invasive surgery are among the most promising advances in this field.

Aim. This study aimed at assessing Doppler ultrasonographic findings of gut wall vessels and thickness in active and quiescent ulcerative colitis. Methods. Fifty patients with ulcerative colitis were studied using transabdominal grayscale and Doppler sonography of sigmoid, distal and middle parts of descending colon in different stages of the disease. Thickness of colon wall in the most involved site, number of color signals in each box, resistive index (RI), and pulsatility index (PI) were evaluated. Results. The median thickness of the colon wall in the most involved sites was 4.3 mm in acute phase and 4.4 mm in the inactive phase (P = 0.47). The median number of the color signals in the active phase at the most involved site, distal part of descending colon and sigmoid was higher than that of the color signals in the inactive phase (P = 0.0001). In the most involved site, the PI and RI were undetectable in the inactive phase. The median PI was 1.4 in the mild phase, 1.3 in the moderate phase, and 1.1 in the severe phase (P = 0.002). Conclusion. In contrast to the colon wall thickness, increased intramural blood flow reflected the clinical severity in ulcerative colitis patients.

Ulcerative colitis is a chronic disease that specifically affects the mucosa of the rectum and colon. Although the etiology of this recurring inflammatory disorder remains essentially unknown, there have been significant advances in identifying the likely genetic and environmental factors that contribute to its pathogenesis. The clinical course of the disease typically manifests with remissions and exacerbations characterized by rectal bleeding and diarrhea. Since ulcerative colitis most commonly affects patients in their youth or early middle age, the disease can have serious long-term local and systemic consequences. There is no specific medical therapy that is curative. Although medical therapy can ameliorate the inflammatory process and control most symptomatic flares, it provides no definitive treatment for the disease. Proctocolectomy or total removal of the colon and rectum provides the only complete cure; however, innovative surgical alternatives have eliminated the need for a permanent ileostomy. The aim of this review is to provide a detailed account of the surgical management of ulcerative colitis.

5-Aminosalicylate agents are the main therapeutic agents for ulcerative colitis. Balsalazide is a prodrug of 5-aminosalicylate and has fewer side effects than the other 5-aminosalicylate agents. Pulmonary complications resembling granulomatosis with polyangiitis in ulcerative colitis are extremely rare. Here, we report a patient with ulcerative colitis on balsalazide presenting respiratory symptoms and multiple pulmonary nodules from a chest radiography that was pathologically diagnosed with a limited form of granulomatosis with polyangiitis with bronchiolitis obliterans organizing pneumonia-like variant. To our knowledge, this is the first report of a balsalazide-induced limited form of granulomatosis with polyangiitis with bronchiolitis obliterans organizing pneumonia-like variant.

ST25 is a key acupoint used in the treatment of ulcerative colitis by moxibustion stimulation, but the biophysical mechanism underlying its effects is still unknown. The aim of the present study was to explore the biophysical properties of ST25 acupoint stimulated by moxibustion in a rat model of ulcerative colitis. The infrared radiation intensity of fourteen wavelengths of ST25 showed significant differences between the normal and model control groups. The intensity of infrared radiation of forty wavelengths showed significant differences compared with the corresponding control points in normal rats. The intensity of infrared radiation of twenty-eight wavelengths showed significant differences compared with the corresponding control points in model rats. The intensity of infrared radiation of nine wavelengths in the herb-partition moxibustion group, eighteen wavelengths in the ginger-partition moxibustion group, seventeen wavelengths in the garlic-partition moxibustion group, and fourteen wavelengths in the warming moxibustion group of the left ST25 showed significant differences compared with that of the model control group. For the right-hand-side ST25, these values were 33, 33, 2, and 8 wavelengths, respectively. This indicated that one possible biophysical mechanism of moxibustion on ST25 in ulcerative colitis model rats might involve changes in the intensity of infrared radiation of ST25 at different wavelengths.

Crohn’s disease and ulcerative colitis are chronic, relapsing inflammatory disorders of the GI tract. In both Crohn’s disease and ulcerative colitis, leukocytic infiltration of the mucosa is associated with epithelial damage. Recently, monoclonal antibodies directed against cell adhesion molecules (CAMs) involved in leukocyte extravasation have been developed. Natalizumab, the first drug brought to market targeting CAMs, is clinically effective but is associated with serious adverse effects including the uncommon, but often fatal, neurological disease progressive multifocal leukoencephalopathy. Vedolizumab targets a subset of the CAMs blocked by natalizumab and is currently in Phase III trials to study its efficacy and safety in patients with inflammatory bowel disease. Here, we discuss the current treatment options available for patients with Crohn’s disease or ulcerative colitis, the history of CAM inhibitors, the current state of development of vedolizumab and its future role in inflammatory bowel disease, if approved by regulatory agencies.

Linear IgA dermatosis has been increasingly associated with inflammatory bowel diseases, particularly ulcerative colitis. A 13-year-old male patient with an 11-month history of ulcerative colitis developed vesicles, pustules and erosions on the skin of the face, trunk and buttocks and in the oral mucosa. The work-up revealed a neutrophil-rich sub-epidermal bullous disease and linear deposition of IgA along the dermoepidermal junction, establishing the diagnosis of linear IgA dermatosis. The patient experienced unsatisfactory partial control of skin and intestinal symptoms despite the use of adalimumab, mesalazine, prednisone and dapsone for some months. After total colectomy, he presented complete remission of skin lesions, with no need of medications during two years of follow-up. A review of previously reported cases of the association is provided here and the role of ulcerative colitis in triggering linear IgA dermatosis is discussed.

Ulcerative colitis is a chronic inflammatory bowel disease of unknown etiopathogenesis and increasing incidence in recent years. Perianal complications of ulcerative colitis are rare and seem to be associated with higher extent of inflammation and a more severe course of the disease. The cases of two male patients with severe corticoid-dependent ulcerative colitis of protracted clinical course who developed perianal fistulas and abscesses successfully treated with infliximab are reported. Treatment with infliximab was followed by perianal fistula closure with marked improvement in the quality of life over 2-year follow-up period.

This case report describes a case of ulcerative colitis the onset of which occurred after the use of isotretinoin for acne treatment. Our patient, a healthy male young adult, after several months of isotretinoin use, developed gastrointestinal disorders and after thorough medical workup was diagnosed with ulcerative colitis. The literature regarding a possible correlation between isotretinoin use and ulcerative colitis is scarce. Nevertheless, recent epidemiological studies have shed more light on this possible association.

To alert clinicians to a potential novel adverse drug effect of interferonβ 1a, we herein report a patient with relapsing-remitting multiple sclerosis who developed ulcerative colitis following treatment with interferonβ 1a. Ulcerative colitis persisted despite discontinuation of interferonβ 1a treatment and switching the patient to glatiramer acetate. Tacrolimus (FK506), 6-mercaptopurine, and prednisolone were required to induce remission. Both ulcerative colitis and multiple sclerosis were eventually well controlled using this regimen. Our report underscores that caution should be exercised when prescribing immunostimulatory agents in patients with inflammatory bowel disease (IBD) and challenges current efforts to stimulate innate immunity as a novel therapeutic concept for IBD.

Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by exacerbations and remissions. The degree of inflammation as assessed by conventional colonoscopy is a reliable parameter of disease activity. However, even when conventional colonoscopy suggests remission and normal mucosal findings, microscopic abnormalities may persist, and relapse may occur later. Patients with long-standing, extensive ulcerative colitis have an increased risk of developing colorectal cancer. Ulcerative colitis-associated colorectal cancer is characterized by an early age at onset, poorly differentiated tumor cells, mucinous carcinoma, and multiple lesions. Early detection of dysplasia and colitic cancer is thus a prerequisite for survival. A relatively new method, magnifying chromoscopy, is thought to be useful for the early detection and diagnosis of dysplasia and colitic cancer, as well as the prediction of relapse.

Expression of matrix metalloproteinase 9 (MMP9) is elevated in a variety of inflammatory and oncology indications, including ulcerative colitis and colorectal cancer. MMP9 is a downstream effector and an upstream mediator of pathways involved in growth and inflammation, and has long been viewed as a promising therapeutic target. However, previous efforts to target matrix metalloproteinases (MMPs), including MMP9, have utilized broad-spectrum or semi-selective inhibitors. While some of these drugs showed signs of efficacy in patients, all MMP-targeted inhibitors have been hampered by dose-limiting toxicity or insufficient clinical benefit, likely due to their lack of specificity. Here, we show that selective inhibition of MMP9 did not induce musculoskeletal syndrome (a characteristic toxicity of pan-MMP inhibitors) in a rat model, but did reduce disease severity in a dextran sodium sulfate-induced mouse model of ulcerative colitis. We also found that MMP9 inhibition decreased tumor growth and metastases incidence in a surgical orthotopic xenograft model of colorectal carcinoma, and that inhibition of either tumor- or stroma-derived MMP9 was sufficient to reduce primary tumor growth. Collectively, these data suggest that selective MMP9 inhibition is a promising therapeutic strategy for treatment of inflammatory and oncology indications in which MMP9 is upregulated and is associated with disease pathology...

Genome-wide association studies of the related chronic inflammatory bowel diseases (IBD) known as Crohn’s disease and ulcerative colitis have shown strong evidence of association to the major histocompatibility complex (MHC). This region encodes a large number of immunological candidates, including the antigen-presenting classical HLA molecules1. Studies in IBD have indicated that multiple independent associations exist at HLA and non-HLA genes, but lacked the statistical power to define the architecture of association and causal alleles2,3. To address this, we performed high-density SNP typing of the MHC in >32,000 patients with IBD, implicating multiple HLA alleles, with a primary role for HLA-DRB1*01:03 in both Crohn’s disease and ulcerative colitis. Significant differences were observed between these diseases, including a predominant role of class II HLA variants and heterozygous advantage observed in ulcerative colitis, suggesting an important role of the adaptive immune response to the colonic environment in the pathogenesis of IBD.

We evaluated the effect of medically induced symptomatic disease improvement on in vitro tests of cell-mediated immune responses in 33 patients with Crohn's disease. When results obtained in 17 patients with ulcerative colitis were compared with those of 10 patients with ulcerative colitis who had undergone a colectomy, no significant correlation was detected between individual clinical and laboratory variables or the Crohn's disease activity index and in vitro tests of cell-mediated immunity. A different pattern emerged from the longitudinal tests of cell-mediated immunity: when these test results were initially abnormal in patients with Crohn's disease, clinical improvement as assessed by the Crohn's disease activity index was associated with normalizing cell-mediated immunity. In contrast, when the test results were initially normal, clinical improvement was not associated with any change in the immune response. Following colectomy in patients with ulcerative colitis, some abnormalities of suppressed immune responses remained, although patients were cured of their disease. Factors other than clinical disease activity may be responsible for the suppressed immunoresponsiveness in some patients with inflammatory bowel disease, and variable changes in cell-mediated immunity occur after both surgical and medical treatment.

Corticosteroid or 5-aminosalicylic acid enemas are the treatment of choice for distal ulcerative colitis but up to one third of patients may be unresponsive. As an alternative therapy might be advantageous, the efficacy of six weeks' treatment with 2 g 4-aminosalicylic acid (4-ASA) (n = 24) and 20 mg prednisolone enemas (n = 21) were compared in a double blind, randomised trial in patients with acute distal (less than 30 cm from the anus) ulcerative colitis. Baseline demography and clinical severity were similar in both groups. Five of 24 patients receiving 4-ASA and 4 of 21 receiving prednisolone did not complete the trial because of deteriorating symptoms, failure to improve, or side effects. At the time of leaving the trial, 24 hour stool frequency, the presence of blood in the stools, and histological and sigmoidoscopic appearances were similar in both groups. Symptomatic improvement occurred in 17 of 24 patients receiving 4-ASA compared with 11 of 21 receiving prednisolone (chi 2 = 1.62, NS). Complete symptomatic improvement occurred in 9 of 24 patients receiving 4-ASA compared with 5 of 21 receiving prednisolone (chi 2 = 0.98, NS). Histological improvement was seen in 9 of 24 patients on 4-ASA compared with 7 of 21 on prednisolone (chi 2 = 0.08...

The cellular infiltrate of the proximal jejunum has been compared between 20 subjects without gastrointestinal disease, 20 subjects with ulcerative colitis, and 26 subjects with Crohn's disease. A significant increase (P smaller than 0.001) in the plasma cell infiltrate was noted in subjects with ulcerative colitis and a more marked increase in subjects with Crohn's disease (P smaller than 0.001). Such increases may be relevant to raised serum IgA levels following panproctocolectomy for ulcerative colitis or recurrence in the small intestine in Crohn's disease.

The detection of a nuclear anti-neutrophil antibody in patients with primary sclerosing cholangitis (PSC), using an immunoperoxidase technique, was recently reported by us. Subsequently, detection of a cytoplasmic anti-neutrophil antibody was reported by others, using a two stage procedure of enzyme linked immunosorbent assay followed by an immunofluorescent method. Detection of cytoplasmic anti-neutrophil antibody in PSC, which, in contrast to that two stage procedure, uses a simple one step immuno-alkaline phosphatase method is now reported. Normal human neutrophils were cytocentrifuged, ethanol fixed, and then incubated with coded patients' sera. Rabbit anti-human immunoglobulin conjugated with alkaline phosphatase was used to detect the bound antibody. Fast red was used to visualise the reaction. Twenty three of 30 (77%) PSC patients showed positive granular cytoplasmic staining (with some perinuclear accentuation) with a network of cytoplasmic filaments. Fifteen of 45 (33%) ulcerative colitis patients and 1 of 3 chronic active hepatitis patients showed similar staining. Thirty five of 152 patients with ulcerative colitis, chronic active hepatitis, and a variety of other liver diseases showed a different pattern of cytoplasmic labelling...

Colonic mucus production was measured in vitro by means of incorporation of tritiated glucosamine using biopsy material from patients with ulcerative colitis and compared with data from patients with Crohn's disease, colonic carcinoma, colonic polyps and patients with apparently normal colonic mucosae. Mucus production was significantly decreased (p less than 0.03) in all patients with ulcerative colitis, and in particular in patients with inactive disease when compared with normal subjects. In patients with active disease mucus production was not significantly different from normal subjects. The radiolabelled material was characterised by gel filtration and ion exchange liquid chromatography as mainly high molecular weight glycoproteins. These results indicate that the quantitative character of colonic mucus is abnormal in inactive ulcerative colitis.
