Inflammatory bowel disease in Iceland, 1980-89. A retrospective nationwide epidemiologic study.

BACKGROUND: A previous nationwide epidemiologic study of inflammatory bowel disease (IBD) in Iceland in 1950-79 showed a low but steadily rising incidence. The incidence of IBD in Iceland in 1980-89 was investigated and compared with reports from neighboring countries. METHODS: Cases were retrieved by a review of all small- and large-intestinal tissue specimens with any type of inflammation submitted to the only two departments of pathology in Iceland. All small-intestinal X-ray records suggestive of Crohn's disease (CD) in the three major hospitals were also screened. All hospital and outpatient records of cases suggestive of IBD were then reviewed using accepted criteria for confirmation or exclusion. RESULTS: The mean annual incidence of ulcerative colitis (UC) was 11.7/100,000, and that of CD 3.1/100,000. The highest age-specific incidence of UC was in the group 30-39 years old and for CD in the group 60-69 years old. The most frequent involvement at diagnosis of UC was proctitis only, in 54%, and in CD colon only, in 54.7% of the patients. CONCLUSIONS: This study shows a continuing increase in the incidence of both diseases. Compared with the period 1970-79, there has been an almost twofold increase in the mean annual incidence of UC and more than a threefold increase of CD, a statistically significant increase in both instances.

Long-term outcome of total colectomy and ileostomy for Crohn disease.

BACKGROUND: This study was undertaken to review long-term results of total colectomy and end ileostomy for Crohn disease. METHODS: Sixty-nine patients who underwent total colectomy and end ileostomy with an oversewn rectal stump for Crohn disease between 1962 and 1997 were reviewed. Postoperative complications, fate of the rectum or small-bowel recurrence, factors affecting complications and recurrence rates, and risk of rectal carcinoma are discussed. RESULTS: Fourteen patients had an emergency colectomy. There were no operative or postoperative deaths. In all except five patients symptoms were rapidly relieved. The commonest postoperative complication was an intra-abdominal sepsis (12%). Only five patients (7%) underwent ileorectal anastomosis, of whom two required proctectomy later. Overall, 37 patients (54%) required proctectomy, with a median duration of 2 years. Sixteen patients (23%) developed small-bowel recurrence requiring surgery, with a median duration of 6.8 years. None of the following factors affected the proctectomy rate: sex, age at operation, duration of symptoms, smoking, perforating disease, coexisting small-bowel disease, preoperative proctitis, perianal disease, emergency operation, postoperative complications, or medical treatment. Youth was the only factor associated with a significantly higher reoperation rate for small-bowel recurrence. One patient developed an adenocarcinoma in a rectovaginal fistula, which was curatively resected at proctectomy. CONCLUSIONS: Total colectomy and end ileostomy is a safe and effective procedure. However, a few patients underwent ileorectal anastomosis, and half of the patients required proctectomy. The small-bowel recurrence rate is low. Regular surveillance of the retained rectum is advised because of a small cancer risk.

Proctocolectomy is associated with a higher complication rate but carries a lower recurrence rate than total colectomy and ileorectal anastomosis in Crohn colitis.

BACKGROUND: Most patients with extensive colonic Crohn disease are treated with total colectomy and ileorectal anastomosis or, when there is severe anorectal disease, with proctocolectomy. This study was undertaken to compare postoperative complications and recurrence rates for these two operations. METHODS: Eighty-six patients who underwent a single-stage proctocolectomy and 65 who underwent total colectomy and ileorectal anastomosis for colonic Crohn disease were retrospectively reviewed. RESULTS: Anorectal disease (severe proctitis, perianal sepsis, complex fistula) was seen in 77 patients (90%) at proctocolectomy, compared with 7 patients (11%) at colectomy and ileorectal anastomosis (P < 0.0001). After proctocolectomy the commonest complication was perineal wound sepsis (36%). After colectomy and ileorectal anastomosis only three patients (5%) developed anastomotic leak. The overall complication rate was 53% after proctocolectomy compared with 32% after colectomy and ileorectal anastomosis (P = 0.02). Twenty-four patients (29%) after proctocolectomy and 43 patients (68%) after colectomy and ileorectal anastomosis developed symptomatic recurrence (P < 0.0001). After proctocolectomy the 5-, 10-, and 15-year cumulative reoperation rate for recurrence were 13%, 16%, and 26%, which were significantly lower than the 29%, 46%, and 48% after colectomy and ileorectal anastomosis (P = 0.002). CONCLUSIONS: The overall complication rate was lower after colectomy and ileorectal anastomosis than after proctocolectomy. However, proctocolectomy was associated with a lower incidence of reoperation for recurrence than colectomy and ileorectal anastomosis.

Diagnostic and clinical implications of anorectal lymphogranuloma venereum in men who have sex with men: a retrospective case-control study.

BACKGROUND: Recently, outbreaks of anorectal lymphogranuloma venereum (LGV) have occurred among men who have sex with men (MSM). This study identifies risk factors and clinical predictors of LGV to determine the implications for clinical practice. METHODS: The Chlamydia trachomatis serovars for all MSM who had anorectal chlamydia diagnosed at a sexually transmitted infection clinic in Amsterdam, The Netherlands, in 2002 and 2003 were retrospectively typed; 87 persons were infected with C. trachomatis serovar L2b and received a diagnosis of LGV. MSM infected with C. trachomatis serovars A-K and who thus had non-LGV anorectal chlamydia (n = 377) and MSM who reported having receptive anorectal intercourse but who did not have anorectal chlamydia (n = 2677) served as 2 separate control groups. Risk factors and clinical predictors were analyzed by multivariate logistic regression. Receiver operating characteristic curves were used to determine clinical relevance. RESULTS: HIV seropositivity was the strongest risk factor for LGV (odds ratio for patients with LGV vs. those with non-LGV chlamydia, 5.7 [95% confidence interval, 2.6-12.8]; odds ratio for patients with LGV vs. control subjects without chlamydia, 9.3 [95% confidence interval, 4.4-20.0]). Proctoscopic findings and elevated white blood cell counts in anorectal smear specimens were the only clinically relevant predictors for LGV infection (area under the curve of the receiver operating characteristic curve, > 0.71). Use of these 2 parameters and HIV infection status provided the highest diagnostic accuracy (for MSM with anorectal chlamydia, the area under the curve was > 0.82; sensitivity and specificity were 89% and 50%, respectively). CONCLUSIONS: LGV testing is recommended for MSM with anorectal chlamydia. If routine LGV serovar typing is unavailable, we propose administration of syndromic LGV treatment for MSM with anorectal chlamydia and either proctitis detected by proctoscopic examination, > 10 white blood cells/high-power field detected on an anorectal smear specimen, or HIV seropositivity.

Lymphogranuloma venereum in the United kingdom.

BACKGROUND: Over the past 2 years, lymphogranuloma venereum (LGV), caused by L serovars of Chlamydia trachomatis, has emerged as a significant problem among men who have sex with men (MSM). We report on, to our knowledge, the largest case series of LGV to date, with detailed epidemiological and clinical characteristics of the epidemic in the United Kingdom. METHODS: A national diagnostic service and surveillance system was established in October 2004. Cases were confirmed by the presence of C. trachomatis and an LGV serovar (L1, L2, or L3) from genotyping. For confirmed cases, an enhanced surveillance questionnaire was sent to the clinician. RESULTS: Through February 2006, a total of 327 cases of LGV were confirmed. Cases were diagnosed across the United Kingdom, with the majority from London (71%) and Brighton (13%). Case reports were received for 282 MSM. The majority (96%) had proctitis, many with severe local and systemic symptoms. There was a high level of coinfection with human immunodeficiency virus (76%), hepatitis C (19%), and other sexually transmitted infections (39%). Nine cases of human immunodeficiency virus infection were diagnosed around the same time as LGV. Most cases were acquired within the United Kingdom, although patients with early cases were more likely to report contacts in The Netherlands. CONCLUSIONS: We found a significant burden of this once-rare sexually transmitted infection among MSM in the United Kingdom. LGV may be contributing to the epidemic of human immunodeficiency virus infection by facilitating transmission. Further control efforts are required, including awareness campaigns, continued detailed surveillance, and expanded chlamydia testing among MSM.

Capecitabine in combination with preoperative radiation therapy in locally advanced, resectable, rectal cancer: a multicentric phase II study.

BACKGROUND: The aim of the study was to evaluate tolerance and efficacy of preoperative treatment with capecitabine in combination with radiation therapy (RT) in patients with locally advanced, resectable, rectal cancer. PATIENTS AND METHODS: Fifty-three patients with potentially resectable T3, N0-2 (87%) and T4, N0-2 (13%) rectal cancer were treated with capecitabine (825 mg/m2, twice daily for 7 days/week) and concomitant RT (50.4 Gy/28 fractions). Patients underwent surgery after 6-8 weeks followed, upon physician's indications, by 4-months adjuvant capecitabine. The primary end point was to determine the rate of pathologic complete response. Secondary end points were to assess the rate of clinical response and the safety profile. RESULTS: All patients but two completed the RT programme and 47 (89%) received 81%-100% of the capecitabine dose (100% of dose in 72% patients, 81%-95% in 17% patients and 48%-74% in 11% of patients). No patient had grade 4 toxicity. Grade 3 toxicity occurred in six patients (11%) and consisted mainly of leucopenia (4%) and hand-foot syndrome (4%). Mild or moderate toxicity was common and included leucopenia (72%), diarrhea (40%), proctitis (34%) and skin toxicity (20%). The overall clinical response rate was 58% and the downstaging rate was 57%, with a pathologic complete response rate of 24%. Among 34 patients with low-lying tumors (<or=5 cm from anal verge), 20 (59%) had a sphincter-saving operation. CONCLUSIONS: Preoperative chemoradiation with capecitabine and RT appeared to be effective in locally advanced resectable, rectal cancer. The favorable safety profile of the combination might warrant the use of capecitabine and RT with other effective new drugs.

Chlamydia trachomatis: impact on human reproduction.

Chlamydia trachomatis infections are the most prevalent bacterial sexually transmitted infections (STI) recognized throughout the world. Worldwide, the magnitude of morbidity associated with sexually transmitted chlamydial infections is enormous. C.trachomatis is a common cause of urethritis and cervicitis, and sequelae include pelvic inflammatory disease (PID), ectopic pregnancy, tubal factor infertility, epididymitis, proctitis and reactive arthritis. The sharp worldwide increase in the incidence of PID during the past two decades has led to the secondary epidemics of tubal factor infertility and ectopic pregnancy. Chlamydial PID is the most important preventable cause of infertility and adverse pregnancy outcome. Chlamydial infections, like STI in general, are primarily a woman's health care issue since the manifestations and consequences are more damaging to the reproductive health in women than in men. Based on the available evidence, approximately 20% of women with chlamydial lower genital tract infection will develop PID, approximately 4% develop chronic pelvic pain, 3% infertility, and 2% adverse pregnancy outcome. However, these estimates are based on relatively weak evidence. Research on the link between C.trachomatis and male aspects of infertility has been much more limited. Currently recommended treatment regimens include azithromycin in a single dose or doxycycline for 7 days. These therapies are highly efficacious. Timely management of sex partners is essential for decreasing the risk for re-infection. Immunopathogenesis of C.trachomatis infection is one of the main focal points of current research into Chlamydia. Chlamydial infection fills the general prerequisites for disease prevention by screening, i.e. chlamydial infections are highly prevalent, usually asymptomatic, are associated with significant morbidity, can be reliably diagnosed, and are treatable. Screening programmes for C.trachomatis will be of paramount importance in the prevention of long-term sequelae. The cost of screening is only a fraction of the health care costs incurred due to complications resulting from undiagnosed and untreated chlamydial infections. Current strategies to control C.trachomatis still largely depend on clinic-based screening of symptomatic patients, and have not been successful. The development of highly sensitive and specific nucleic acid amplification tests for the diagnosis of chlamydial infections has been an important advance in the ability to conduct population-based screening programmes to prevent complications. Thus, the case for screening is clearly made, but much detail remains to be worked out.

Campylobacter cinaedi (sp. nov.) and Campylobacter fennelliae (sp. nov.): two new Campylobacter species associated with enteric disease in homosexual men.

In a recent study in Seattle, we isolated Campylobacter-like organisms (CLOs) significantly more often from homosexual men with intestinal symptoms than from asymptomatic heterosexual and homosexual control subjects. Biochemical tests, morphology, and guanine-plus-cytosine content of whole-cell DNA showed that these organisms were similar to, but distinguishable from, other species in the genus Campylobacter. DNA homology tests showed that the Campylobacter-like organisms belong to four unique genetic groups, two of which were phenotypically identical. We developed a rapid screening test to genetically group these organisms and to assess the correlation of each genotype with enteric disease in homosexual men. Three of the four CLO groups were isolated only from men with proctitis, proctocolitis, and/or enteritis. The remaining group, isolated from both symptomatic and asymptomatic homosexual men, was significantly correlated with the presence of polymorphonuclear leukocytes in the rectal secretions of asymptomatic men, a finding that suggests subclinical disease. We have tentatively classified two of the CLO groups into species, Campylobacter cinaedi sp. nov. and Campylobacter fennelliae sp. nov.

Toxicity and health-related quality of life during and after high dose rate brachytherapy followed by external beam radiotherapy for prostate cancer.

BACKGROUND: The optimal protocol for combining high dose rate brachytherapy and external beam irradiation as treatment for localized prostate cancer is unknown. Toxicity rates and clinical and biochemical outcomes should be evaluated to validate the current treatment protocol. METHODS: Fifty-eight patients were treated for prostate cancer with high dose rate brachytherapy followed by 30 Gy of external beam radiation therapy. Toxicity during treatment and for 12-18 months thereafter, and treatment-related morbidity, were evaluated. Physician-assessed treatment-related toxicity was graded at the time of occurrence using the Radiation Therapy Oncology Group morbidity criteria. Four separate self-administered questionnaires were used to collect longitudinally demographic data and general and prostate disease-related measures of quality of life. RESULTS: Various degrees of rectal bleeding due to radiation proctitis were experienced by 13 patients (22%) at a median time of 11 months. Two of these patients needed hospitalization to undergo laser coagulation of the rectal mucosa. Study patients had statistically significant decreases in five SF-36 domains during the first month of treatment. All measures recovered by 12 months. Sexual function was not affected by irradiation. Lower urinary tract symptoms assessed by IPSS/QOL scores worsened significantly during the first month of treatment but later recovered to baseline levels. Physician-assessed RTOG scores failed to detect these changes. CONCLUSIONS: Morbidity associated with combined radiation therapy was greatest during the first month of treatment and affected quality of life significantly. Most measures recovered to baseline levels by 12 months following radiation therapy. Although the current protocol appears acceptable, measures should be taken to decrease treatment-related morbidity further.

Long-term outcomes of 60 Gy conventional radiotherapy combined with androgen deprivation for localized or locally advanced prostate cancer.

BACKGROUND: Until 1998 in Japan, very few institutions were treating prostate cancer solely with radiotherapy (RT) >70 Gy and most were using < or =65 Gy in combination with hormone therapy. The present study reports the long-term results of RT combined with hormone therapy for localized and locally advanced prostate cancer. METHODS: We investigated 57 patients who were treated by external beam RT plus hormone therapy (median age 79 years, median prostate-specific antigen concentration 15.0 ng/ml) between 1992 and 1998. Patients received 40 Gy of radiation to the pelvis and an additional 20 Gy as a prostatic boost. Hormone therapy was begun on the first day of irradiation and continued thereafter. RESULTS: The median follow-up was 93.3 months and the 5 and 10 year actual overall survival rates were 67.8 and 32.6%, respectively, with 5 and 10 year cause-specific survival rates of 97.9 and 95.0%, respectively. The expected survival rate was 66.2% at 5 years, and overall survival was above expected survival. Only one patient developed severe proctitis (Grade 3). The 5 year occurrence of Grade 1/2 genitourinary toxicity was 23.2%. CONCLUSIONS: Combined RT and hormone therapy has a good long-term outcome without severe adverse events. The overall survival rate compares well with the expected survival rate.

Risk factors for ileoanal J pouch-related septic complications in ulcerative colitis and familial adenomatous polyposis.

OBJECTIVE: To analyze the association between pre- and perioperative factors and pouch-related septic complications (PRSC) in ulcerative colitis (UC) and in familial adenomatous polyposis (FAP) after ileal pouch-anal anastomosis (IPAA). SUMMARY BACKGROUND DATA: For patients with UC and FAP, IPAA is the surgical therapy of choice, but in some patients the outcome is compromised by PRSC. METHODS: A total of 706 consecutive patients (494 UC, 212 FAP) were assessed in a study aimed at identifying subgroups of patients who were at high risk for PRSC. The rate of PRSC was analyzed as a time-dependent function (Kaplan-Meier estimation). Patients with UC and FAP were stratified separately according to associated factors (age, sex, surgeon's experience, temporary ileostomy, colectomy before IPAA, anastomotic tension, and several factors specific for UC). RESULTS: In all, 131 (19.2%) patients had PRSC (23.4% UC, 9.4% FAP). In patients with UC, the estimated 1-year PRSC rate was 15.6% and the estimated 3-year PRSC rate was 24.2%. In patients with FAP, the estimated 1-year and 3-year PRSC rates were 9.2%. The difference between the estimated rates of PRSC was significant (P <.001). In the univariate analysis, patients with UC younger than 50 years, with severe proctitis, with preoperative hemoglobin levels less than 10 g/L, or receiving corticoid medication had a significantly higher risk for PRSC (P =.039, P =.037, P =.047, P =.003, respectively). Multivariate analysis showed that patients with UC receiving a systemic prednisolone-equivalent corticoid medication of more than 40 mg/day had a significantly greater risk of developing pouch-related complications than patients with UC receiving 1 to 40 mg/day and patients with UC who were not receiving corticoid medication (RR: 3.78, 2.25, 1, respectively, P <.001). Patients with FAP proved to have a significantly higher risk for PRSC in the univariate and multivariate analyses if anastomotic tension had occurred (RR 3.60, P =.0086). CONCLUSIONS: Pouch-related septic complications occur as late complications and should therefore be considered in regular, specific long-term follow-up examinations. The authors identified significant risk factors for PRSC specific to patients with UC and FAP; these must be considered for each individual surgical strategy.

Chemoradiation with gemcitabine for cervical cancer in patients with renal failure.

The prognosis of cervical cancer patients with renal failure secondary to obstructive uropathy is poor. Our objective was to analyze our experience in the management with chemoradiation of untreated cervical cancer patients complicated by obstructive nephropathy and kidney dysfunction. Untreated patients with cervical cancer and renal failure as manifested by raised serum creatinine were treated with pelvic radiotherapy concurrently with weekly gemcitabine at 300 mg/m2. Response, toxicity and renal function pre- and post-therapy were evaluated. Eight FIGO stage IIIB and one IVB patients were treated. Pre-treatment serum creatinine ranged from 1.6 to 18.5 mg/100 ml (median 3.3, mean 6.8) and creatinine clearance varied from 4 to 57 mg/ml/min (median 17, mean 22.1). Four patients had a percutaneous nephrostomy placed and four patients had symptoms from kidney failure. All patient completed chemoradiation. Most patients had grade 3 leukopenia and neutropenia. Dermatitis, colitis and proctitis were common. All patients had improvement in creatinine clearance (pre-therapy 22.78, post-therapy 54.3 mg/ml/min) (p=0.0058) and all but one normalized serum creatinine. Eight (89%) of nine patients achieved complete response and one patient had persistence. At a median follow-up of 11 months (range 6-14), all patients are alive, one with pelvic and another with systemic disease. Ureteral obstruction causing any degree of renal insufficiency should not be a contraindication to receive chemoradiation to attempt cure. In this setting where cisplatin-based therapy is contraindicated, the use of gemcitabine may be considered.

5-Aminosalicylic acid as enemas or suppositories in distal ulcerative colitis?

Thirty-nine patients with documented active distal proctitis (less than 20 cm) received either 5-aminosalicylic acid (5-ASA) enemas (2 g in 100 ml) or suppositories 1 g b.i.d., in a controlled study. Twenty patients received enemas, while 19 patients received suppositories, for 30 days. No difference could be observed in terms of efficacy; however, it was the patients' opinion that treatment with suppositories was easier than that with enemas (p less than 0.01).

Prevalence of ulcerative colitis in the Israeli kibbutz population.

We carried out an epidemiological study of ulcerative colitis in 279 Israeli kibbutzim (121,403 population). The prevalence on December 31, 1987 was 121.08 per 100,000 population. When the data were stratified according to ethnic groups, the highest point prevalence was found in Israeli-born Jews (220.56 per 100,000 population), more than in Asian-African-born, or European-American-born kibbutz members (139.20 and 78.73 cases per 100,000 population, respectively). There were 68 men and 78 women (ratio of 0.87). The average age of the patients in the year of this survey was 46 years; it was 35 years at the time of diagnosis. Proctitis was found in 57%, left-sided colitis in 12%, and substantial or total colitis in 31%. Relapse at pregnancy was demonstrated in seven patients, and remission in one. Family history of a first-degree relative with inflammatory bowel disease was documented in three patients (2%). Probable complications of ulcerative colitis were observed in 38 (26%), anemia in 13 (9%). One patient (0.7%) with rectal cancer, also had breast cancer. We suggest that the impressive increase in ulcerative colitis prevalence among Israeli and Asian-African-born, in comparison with European-American-born kibbutz members, points toward a role of environmental factors in the etiology of this disease.

Fatal Clostridium difficile enteritis after total abdominal colectomy.

A 71-year-old man who had undergone an ileorectal anastomosis some years earlier, developed fulminant fatal Clostridium difficile pseudomembranous enteritis and proctitis after a prostatectomy. This case and three reports of C. difficile involvement of the small bowel in adults emphasize that the small intestine can be affected. No case like ours, of enteritis after colectomy from C. difficile, has hitherto been reported.

Ulcerative colitis in children 10 years old or younger.

The onset and course of ulcerative colitis diagnosed in 38 children at or before 10 years of age were reviewed. The mean age at onset was 5.9 years. A family history of inflammatory bowel disease was present in 24% of patients, and 13% had a history of cow milk allergy in infancy. Initially, by radiologic or colonoscopic studies, 71% had total colonic disease, 13% had left-sided colitis, and 6% had proctitis; extensive examination was not performed in 4 patients. Four patients (11%) presented with severe colitis, 14 (37%) with moderate colitis, and 20 (53%) with mild colitis. The most frequent symptoms were abdominal pain (94%), diarrhea (84%), and rectal bleeding (84%). Between 2 and 10 years after diagnosis, 89% of children had total colonic disease and 11% had left-sided disease. All four patients with severe disease at onset responded to medical therapy with one having a colectomy 15 years later with pathology consistent with Crohn's disease. Of those with moderate disease, half had infrequent moderate recurrences and half had intermittent mild disease. One patient had colectomy at 21 years for intractable disease. Of the 20 with mild disease, 16 continued to have intermittent mild recurrences, 1 had chronic mild disease, 2 had moderate recurrent disease, and 1 has remained asymptomatic for 5 years. Psychiatric disturbances requiring therapy were identified in 5 (13%) children. Results are encouraging: after the first 2 years of illness, two thirds of the children have had subsequent mild colitis with infrequent relapses and three quarters consider their life to be of good quality.

Fecal calprotectin levels in healthy children studied with an improved assay.

BACKGROUND: Calprotectin is a protein abundant in neutrophils. Fecal calprotectin can be used as a marker of gastrointestinal inflammation, and an improved assay has recently been developed. The aim of this study was to establish reference values for fecal calprotectin in healthy children aged between 4 and 17 years. METHODS: Fecal samples were obtained from 117 healthy children classified into four age groups: 4 to 6 years, 7 to 10 years, 11 to 14 years, and 15 to 17 years. A health questionnaire was used to ensure that these children fulfilled the inclusion criterion and did not have intercurrent disease, nasal or menstrual bleeding, or nonsteroidal anti-inflammatory drug medication before the sampling period. Calprotectin was analyzed using a quantitative enzyme-linked immunosorbent assay (Calprest, Eurospital SpA, Trieste, Italy). Children with fecal calprotectin values >50 microg/g were asked to deliver an additional sample. RESULTS: The overall median fecal calprotectin concentration was 13.6 microg/g (95% confidence interval, 9.9-19.5 microg/g) in the 117 children. In the different age groups, 4 to 6 years, 7 to 10 years, 11 to 14 years, and 15 to 17 years, the median calprotectin concentrations were 28.2, 13.5, 9.9, and 14.6 microg/g, respectively. Of these children, 104 (89%) had a concentration <50 microg/g. The remaining 13 children with a calprotectin concentration >50 microg/g delivered one additional fecal sample. All showed a lower concentration in the second sample except for one teenager who later proved to have proctitis. CONCLUSIONS: The suggested cutoff level for adults (<50 microg/g) can be used for children aged from 4 to 17 years regardless of sex. A fecal calprotectin concentration >50 microg/g warrants follow-up.

Autoimmune pancreatitis associated with immune-mediated inflammation of the papilla of Vater: report on two cases.

Autoimmune pancreatitis (AIP) is defined histologically by periductal and interacinar lymphocytic infiltration. Immunohistochemically, the majority of these lymphocytes are identified as T cells. Epithelial HLA-DR antigen expression was also described as a marker of autoimmunity in this type of chronic pancreatitis. We report 2 cases, a 56-year-old man and a 29-year-old woman, with AIP associated with immune-mediated inflammation of the main duodenal papilla (MDP). Serologically, antinuclear antibody positivity was detected in the male patient. The female patient, treated medically for ulcerative proctitis, had no serological evidence of autoimmune disease. Macroscopic papillitis was present only in the male patient, and endoscopic biopsy samples were taken from this swollen MDP. Since we could not exclude malignancy, a pancreatic head resection was performed in both patients. The histologic and immunohistochemical studies of the resected specimens showed periductal T-lymphocytic infiltration in the pancreatic and papillary tissues. Furthermore, HLA-DR-antigen expression was also demonstrated in epithelial cells of the pancreas and MDP. The immunohistological features of endoscopic biopsy samples from the swollen MDP were identical as in the surgically resected specimens. Immune-mediated inflammation of the MDP may be associated with AIP.
