Idiopathic ulcerative proctitis may be the initial manifestation of Crohn's disease.

Of 213 patients with proctitis of all etiologies seen between 1977 and 1987, we studied an original cohort of 96 patients with idiopathic ulcerative proctitis (mean follow-up of 62 months). The diagnosis was made according to strict inclusion criteria, and all cases with any initial feature suggestive of Crohn's disease were excluded. Follow-up showed that 13 patients (13.6%) eventually progressed to Crohn's disease, usually within the first 3 years of the initial diagnosis of idiopathic ulcerative proctitis. Their clinical, endoscopic and histological features at initial presentation were indistinguishable from those in whom the diagnosis remained that of idiopathic ulcerative proctitis. In nine of 13 of these patients (70.0%), the clinical course was characterized by a more protracted course and a poorer response to standard treatment. Such features were not found in those in whom the diagnosis of idiopathic ulcerative proctitis was maintained. Clinicians should be aware that Crohn's disease may present initially as apparent idiopathic ulcerative proctitis.

Low incidence of ulcerative colitis and proctitis in Bangladeshi migrants in Britain.

To assess the incidence of ulcerative colitis and proctitis in a defined migrant population, a retrospective, epidemiological community study was performed in the London Borough of Tower Hamlets from 1972 to 1989. The population of 164,000 includes 28,000 Bangladeshis. Potential cases were identified from hospital departments of pathology and medical records. There were 107 cases of ulcerative colitis in Europeans and 5 in Bangladeshis. There were 74 and 2 cases of proctitis in these communities, respectively. The mean standardised incidence of ulcerative colitis in Bangladeshis (1.8 cases/10(5)/year) was marginally lower than in Europeans (6.2 cases/10(5)/year, Z = 0.7, n.s.). The mean standardised incidence of proctitis in Bangladeshis was 0.6 cases/10(5)/year and in Europeans 3.2 cases/10(5)/year (Z = 0.6 n.s.). Anatomical extent of colitis was similar in all ethnic communities, although complications were less likely in minority groups. These findings suggest that the incidence of ulcerative colitis and proctitis in Bangladeshis, in Britain, is amongst the lowest in the world.

Acute ischemic proctitis. Report of six cases.

Acute ischemic proctitis is a rare clinical entity caused by vascular insufficiency of the major or collateral circulation to the rectum. It usually occurs following aortic or aortoiliac operations. Six patients with acute ischemic proctitis are presented; four cases occurred after direct arterial interruption, one after accidental embolization of the blood supply to the rectum, and one from tumor edema. Bloody diarrhea was the most common symptom. Loss of anal sphincter tone was also an early sign in three patients. The diagnosis of ischemia was made by mucosal appearance on proctosigmoidoscopy and is differentiated from infectious proctitis by stool culture. Superficial mucosal ischemia was treated without surgery, but deeper levels of necrosis required laparotomy and Hartmann's resection. Rectal excision was not necessary. Four patients survived the ischemic event.

The pathogenesis rectal stricture. II. Experimental salmonellosis and ischemic proctitis.

Experimentally induced oral Salmonella typhimurium infection in pigs resulted in a severe, prolonged enterocolitis with ulcerative proctitis a constant feature. Healed lesions were annular cicatricial ulcers in the part of the rectum affected with rectal strictures. Strictures indistinguishable from the naturally occurring lesion were produced by injecting chlorpromazine into the cranial hemorrhoidal artery of three pigs. Dye injected into the cranial hemorrhoidal artery perfused the entire rectum in normal pigs, but in pigs with either rectal stricture or salmonella proctitis the dye halted at the cranial margin of the transverse mucosal defect. The predilection of rectal stricture and its proposed precursor, salmonella ulcerative proctitis, for the middle third of the rectum was attributed to a normally precarious arterial supply which renders the rectum unusually susceptible to ischemic injury and decreases its reparative capacity.

Maintenance oral sulfasalazine prolongs remission in ulcerative proctitis and proctosigmoiditis.

We have retrospectively compared the effectiveness of five different regimens for inducing and maintaining clinical remission in 206 patients with idiopathic proctitis (n = 115) and proctosigmoiditis (n = 91). The five therapeutic regimens were: corticosteroid enemas, 5-aminosalicylic acid (5-ASA) enemas, oral 5-ASA (sulfasalazine or mesalamine), corticosteroid enemas plus oral 5-ASA, or 5-ASA enemas plus oral 5-ASA. Clinical remission was achieved within 28 days of therapy in 47%, and eventually in 94% of these patients. No significant differences in efficacy were found among the five regimens. Most patients ultimately experienced a recurrence of symptoms, but the duration of remission was significantly longer with maintenance oral sulfasalazine or mesalamine (17.2 months) than with no therapy (11.8 months), P less than 0.01. We conclude that several regimens are equally effective in inducing remission of proctitis and proctosigmoiditis, although prolonged therapy may be needed to accomplish this goal. Maintenance oral 5-ASA significantly prolongs symptomatic remission in proctitis and proctosigmoiditis.

Persistence of proctitis in 2 cases of clindamycin-associated colitis.

Two cases of persisting proctitis after an episode of clindamycin-associated colitis are reported. Both patients had fulminant colitis and required emergency operation. Severe proctitis persisted in the rectal stumps until their removal 8 months after the initial diagnosis of colitis was made. Persisting proctitis has not previously been described in clindamycin-associated colitis.

Immunoglobulin E in rectal mucosa of patients with proctitis.

Rectal-biopsy specimens were obtained from a group of patients with proctitis in different stages of activity. Large numbers of brightly fluorescent IgE-producing cells were demonstrated in rectal-biopsy specimens taken from these patients during disease activity and clinical remission. An immediate hypersensitivity reaction is suggested as one of the mechanisms involved in the pathogenesis of proctitis.

Herpesvirus hominis (type 1) proctitis.

Herpes proctitis from Herpesvirus hominis type 1 is probably an underrecognized cause of rectal pain and inflammation. Extreme anal pain and a purulent rectal discharge in a heterosexual man led to the appropriate diagnosis. Clinicians should be more aware of herpes as a cause of proctitis.

Superimposed traumatic and gonococcal proctitis: report of two cases.

Two men sought treatment at an emergency room with apparent gonococcal proctitis. Further evaluation after failure of antibiotic therapy in both patients revealed that rectal damage resulting from the patients' sexual habits had resulted in a severe traumatic proctitis. The discovery of several organisms, including Neisseria gonorrhoeae and two nonpathogenic amebas, was probably only incidental. Two points are emphasized: the importance of obtaining a complete sexual history for every patient treated for venereal disease, and the inherent complications associated with anorectal manipulation.

Disodium cromoglycate in the treatment of chronic proctitis.

The effect of topical disodium cromoglycate (DSCG) has been examined in 30 patients with chronic active proctitis using a double-blind crossover trial. Each treatment period was four weeks and patients were given DSCG 200 mg by enema twice daily and 100 mg orally three times each day. Twenty-six patients completed the trial successfully, 14 responded to DSCG treatment, two improved with placebo, and 10 responded to neither. Patients who responded to DSCG had significantly more eosinophils in their rectal biopsies than those who failed to respond and in some instances the counts were very high. The findings support the hypothesis than an allergic reaction is important in the pathogenesis of proctitis.

Immunohistochemical changes in morphologically involved and uninvolved colonic mucosa of patients with idiopathic proctitis.

Alterations in secretory component, IgA, IgG, and IgM were studied by immunofluorescent techniques in mucosal biopsy specimens obtained at colonoscopy from inflamed and grossly uninvolved colonic mucosa from 12 patients with idiopathic proctitis. Parotid-salivary secretory component and IgA and serum immunoglobulins were also investigated. Decreased secretory IgA was observed in the epithelium of all grossly involved rectal mucosa and in 40% of proximal normal mucosa. Salivary secretory IgA was not diminished. These observations suggest that a local immune defect may be pathogenetically related to idiopathic proctitis.

[5-aminosalicylic acid enema (Pentasa) versus hydrocortisone acetate foam (Proctocort) for the treatment of outbreaks of proctitis and cryptogenetic proctosigmoiditis. A comparative randomized multicenter trial].

The therapeutic efficacy of 1 g 5-aminosalicylic acid enema was compared with that of 90 mg hydrocortisone acetate foam following daily rectal administration to patients with idiopathic proctitis or proctosigmoiditis during two weeks. A total of 199 patients (103 5-aminosalicylic acid, 96 hydrocortisone acetate) were included in a randomized, multicenter trial. Endoscopic and clinical remission was seen in 67 and 69 percent of the 5-aminosalicylic acid-treated and in 50 and 45 percent of the hydrocortisone acetate-treated patients (P less than 0.05), respectively. Mild side effects were seen in 10.7 percent of the 5-aminosalicylic acid-treated patients and in 3.1 percent of the hydrocortisone acetate-treated patients (P = 0.05). After 2 weeks, 5-aminosalicylic acid enemas are more effective than hydrocortisone foam for topical treatment of patients with idiopathic proctitis or proctosigmoiditis.

Aminophylline suppository-induced acute proctitis.

A 9-yr-old boy revealed anal hemorrhage after administration of an aminophylline suppository. Proctosigmoidoscopy demonstrated edema of the rectal mucosa with hyperemia and petechiae. We performed a provocation test and obtained the diagnosis of aminophylline suppository-induced acute hemorrhagic proctitis. One should recognize that acute hemorrhagic proctitis is a rare but important side effect of aminophylline suppositories, because they are commonly used for asthmatic children.

Comparative analysis of systemic immunological parameters in ulcerative colitis and idiopathic proctitis: effects of sulfasalazine in vivo and in vitro.

Comparative analysis of the systemic immunity revealed similarities between ulcerative colitis and idiopathic proctitis. In the active stage of both diseases, circulating complement receptor positive cells were increased whereas T-cell percentages and lymphocyte functions were decreased. In severe forms of ulcerative colitis and idiopathic proctitis circulating EAC-phagocytosing esterase positive cells, indicative of activated monocytes, were demonstrated. Successful treatment with salicylazosulfapyridine (SASP) reversed these immunological changes. Incubation of SASP and its metabolites with leucocytes from patients and control subjects, in concentrations similar to those demonstrated in sera from patients treated with SASP, did not alter the immunological changes.

Methylene blue dye spraying method in patients with ulcerative proctitis: a comparative study with morphological findings and functional capacity of the rectal epithelium.

Methylene Blue dye spraying method is currently used in the endoscopic assessment of the colonic mucosa of patients with chronic ulcerative proctocolitis. We have assessed the validity of this method in the evaluation of the functional capacity of the rectal mucosa in 17 patients with ulcerative proctitis and in 5 normal subjects. The ionic transmucosal fluxes of Na+ and K+ and the potential difference were used as parameters of the mucosal function. Our results indicate that methylene blue dye spraying method can be useful in the functional assessment of the rectal epithelium, especially for differentiating normal subjects and patients with mild ulcerative proctitis.

[Efficacy of a daily application of mesalazine (Pentasa) suppository with progressive release, in the treatment of ulcerative proctitis. A double-blind versus placebo randomized trial].

Therapeutic efficacy of mesalazine controlled-release suppository 1 g once daily was compared with that of a placebo during 2 weeks in 50 patients (26 in the mesalazine group, 24 in the placebo group) with ulcerative proctitis, in a double-blind randomized trial. Endoscopic and clinical remission was seen in 69 and 65% of mesalazine-treated patients and in 33 and 25% of placebo-treated patients respectively (P < or = 0.01). No side effects were seen. It is concluded that a once-a-day administration of 1 g mesalazine controlled-release suppository is effective for topical treatment of patients with ulcerative proctitis.

Idiopathic proctitis. I. The morphology of proximal colonic mucosa and its clinical significance.

A group of 31 patients with idiopathic proctitis were colonoscoped while they were symptomatic. Multiple mucosal biopsies were taken from the transverse, descending, and sigmoid colon and from the rectum. While visualization by colonoscopy revealed abnormalities limited to the most distal 18-20 cm of the colon, microscopic abnormalities were frequently seen in more proximal locations. Analysis of clinicopathological data indicates that there is good correlation between the extent of microscopic mucosal abnormalities and the clinical course. Patients with abnormalities limited to the rectum generally responded well to conventional treatment while patients with more proximal involvement were refractory to such therapy.

Syphilitic proctitis.

Two adult male homosexuals with syphilitic proctitis and without any detectable anal lesions are reported. There was no history or evidence of an external primary chancre in either patient. Of note, one had extensive rectal involvement of the first 20 cm and the other had multiple sites involved. One patient developed severe rectal bleeding following biopsy and a Jarisch-Herxheimer reaction after the first penicillin injection. Salient features of the literature are reviewed and discussed.
