Predictors of health care utilization in patients with inflammatory bowel disease: a longitudinal study

OBJECTIVE: To study the changes in normal sexual behavior that accompany the vulvar vestibulitis syndrome and to gauge an appropriate classification for the resulting sexual dysfunction. STUDY DESIGN: Following full medical screening, questionnaires were administered to assess sexual history, illness behavior and vulvar discomfort. Forty patients who met the criteria of vestibulitis syndrome composed the study cohort. RESULTS: The average duration of reported vulvar pain was 33 months (range, 3-240). The cohort showed no significant differences when compared with normative data on the sexual history form in their level of sexual desire, duration of intercourse or chance of female orgasm with intercourse or masturbation. Patients were: (1) highly likely to experience vulvar pain with intercourse (P < .001), (2) highly likely to have significantly reduced arousal potential (P < .001), (3) highly likely to complain of vulvar symptoms preventing intercourse from occurring (P < .001), (4) highly likely to have a reduced interest in intercourse and to have negative feelings toward it (P < .001); and (5) highly likely to refuse a partner's sexual advances (P < .001). CONCLUSION: In the case of vulvar vestibulitis, the most appropriate Diagnostic and Statistical Manual of Mental Disorders, fourth edition, classification appears to be sexual dysfunction due to a general medical condition.     

Posttraumatic stress disorder among U.S. Army Reserve Vietnam and Vietnam-era veterans.

Analysis of questionnaire data collected in the spring of 1982 from 935 randomly selected Vietnam and Vietnam-era veterans (mean age 36.7 yrs) assigned to US Army Reserve troops units nationwide revealed a posttraumatic stress disorder (PTSD) rate for Vietnam veteran reservists of 10.9%, which is midrange between estimates for civilian (18–54%) and active duty Army (5.1%) Vietnam veterans. Results suggest that the quality of social support received during Vietnam duty and the 1st yr back may serve to either moderate or exacerbate PTSD symptomatology associated with combat experience.

Gastrointestinal pH profiles in patients with inflammatory bowel disease

BACKGROUND: 5-Amino salicylic acid preparations are used in therapy for patients with inflammatory bowel diseases. The bioavailability of these drugs depends on their coating. AIM: To determine whether intraluminal pH is decreased by the presence of inflammation, thereby altering the release of 5-amino salicylic acid in the intestinal lumen. METHODS: Intraluminal gastrointestinal pH was measured by means of a radiotelemetry capsule in 12 healthy controls, in 12 patients with Crohn's disease (five with active disease), and in 11 patients with ulcerative colitis (seven with active disease). RESULTS: The median gastric pH values in the patient groups (Crohn's disease 2.4, range 1.5-4.1; ulcerative colitis 1.95, range 1.55-4.4) were significantly higher than those observed in the controls (1.55, range 0.95-2.6). In the small bowel and colonic segments, all the pH values of Crohn's disease patients were comparable to those of the controls, as were the pH values in the proximal small intestine and in the left colon in patients with ulcerative colitis. However, the latter group had higher pH values in the terminal ileum, the caecum and the right colon. Patients with active disease had comparable median gastrointestinal pH values to patients in remission. CONCLUSIONS: The luminal release of 5-amino salicylic acid might not be inhibited by low pH in patients with active inflammatory bowel diseases. This supports a safe disintegration of the slow release mesalazine preparations even in the presence of severe disease.     

Femoral neck osteopenia in patients with inflammatory bowel disease

Bone morphogenetic proteins (BMPs) are considered to have important regulatory roles in skeletal embryogenesis and bone healing. Recombinant human BMPs (rhBMPs) have been shown to heal critical size defects and promote spinal fusion. We studied the effects of rhBMP-2 in an absorbable collagen sponge (ACS) on bone healing in a large animal tibial fracture model. Bilateral closed tibial fractures were created in 16 skeletally mature goats and reduced and stabilized using external fixation. In each animal, one tibia received the study device (0.86 mg of rhBMP-2/ACS or buffer/ACS), and the contralateral fracture served as control. The device was implanted as a folded onlay or wrapped circumferentially around the fracture. Six weeks following fracture, the animals were sacrificed and the tibiae harvested for torsional testing and histomorphologic evaluation. Radiographs indicated increased callus at 3 weeks in the rhBMP-2/ACS treated tibiae. At 6 weeks, the rhBMP-2/ACS wrapped fractures had superior radiographic healing scores compared with buffer groups and controls. The rhBMP-2/ACS produced a significant increase in torsional toughness (p = 0.02), and trends of increased torsional strength and stiffness (p = 0.09) compared with fracture controls. The device placed in a wrapped fashion around the fracture produced significantly tougher callus (p = 0.02) compared with the onlay application. Total callus new bone volume was significantly increased (p = 0.02) in the rhBMP-2/ACS fractures compared with buffer groups and controls regardless of the method of device application. The rhBMP-2/ACS did not alter the timing of onset of periosteal/endosteal callus formation compared with controls. Neither the mineral apposition rates nor bone formation rates were affected by rhBMP-2/ACS treatment. The increased callus volume associated with rhBMP-2 treatment produced only moderate increases in strength and stiffness.     

Complementary medicine use by patients with inflammatory bowel disease

Three weak, recumbent neonatal foals with skin lesions, including a thin wooly coat, were born to mares being treated for equine protozoal myeloencephalitis. Mares received sulfadiazine or sulfamethoxazole-trimethoprim, pyrimethamine, folic acid, and vitamin E orally. Foals were anemic, leukopenic, azotemic, hyponatremic, and hyperkalemic. Serum folate concentrations in the 3 foals and 2 mares were lower than those reported in the literature for clinically normal brood mares. Treatment was unsuccessful. For each foal, necropsy revealed lobulated kidneys with thin cortices and a pale medulla, and the spleen and thymus were small. Histologic examination revealed marked epidermal necrosis without inflammatory cells, thin renal cortices, renal tubular nephrosis, lymphoid aplasia, and bone marrow aplasia and hypoplasia. These observations indicate that oral administration of sulfonamides, 2,4-diaminopyrimidines (pyrimethamine with or without trimethoprim), and folic acid to mares during pregnancy is related to congenital defects in newborn foals.     

Suicide in patients with Parkinson''s disease. An epidemiological study

The purpose of this study was to estimate the risk of suicide for patients with Parkinson's disease (PD) in Denmark compared with that in the background population. The study involved 458 patients with a PD diagnosis, 226 men and 232 women. The follow-up period to either death or end of follow-up on December 31, 1990 was 0 to 17 years, mean 5.7 years. Deaths in the follow-up period amounted to 254, 135 men and 119 women. Two women committed suicide. The number of expected suicides was 1.06 for men and 0.55 for women, a total of 1.62. Neither for men nor for women was the difference between expected and observed suicides statistically significant.     

Cellular immunity in patients with non-specific inflammatory bowel disease for an extended period after surgery

The study was aimed at investigating the expression of HLA-DR, CD4, CD8, CD56 surface antigens on peripheral blood lymphocytes in patients with non-specific inflammatory bowel diseases in the period of 1-5 years after the surgical procedure. The percentage of rosette forming T-cells in the theophylline test and skin reaction to mycotic and bacterial antigens were assessed simultaneously. The experiment included group of 12 patients (aged 5-55), treated surgically because of Crohn's disease or ulcerative colitis. The lymphocytes' surface antigens were examined by means of monoclonal antibodies and the APAAP procedure. Significantly increased (p < 0.001) percentage of lymphocytes with HLA-DR surface antigens and significantly decreased (p < 0.002) percentage of lymphocytes with CD8 surface antigens were observed in patients with non-specific inflammatory bowel diseases. In 6 of 12 patients the skin test results were negative. The clinical symptoms, which may suggest the maintaining inflammation of the intestinal mucosa were found in 50% of patients examined after surgical procedure because of Crohn's disease. The results suggest there are significant disturbances of cellular immunoreactivity parameters in patients with non-specific inflammatory bowel diseases. It may be one of the causes, which maintain the chronic inflammation of the intestinal mucosa and favour disease recurrence. The cellular immunoreactivity disturbances demonstrated in this study may be the result of the still persisting intestinal mucosa. Inflammation, in spite of deficiency of synonymous clinical symptoms indicating the disease recurrence.     

Antineutrophil cytoplasmic antibodies in Estonian patients with inflammatory bowel disease. Prevalence and diagnostic role

BACKGROUND/AIMS: In Estonia, the incidence of ulcerative colitis and especially Crohn's disease appears to be rare. Antineutrophil cytoplasmic antibodies (ANCA) are frequently found in ulcerative colitis but less frequently in Crohn's disease, their pathophysiological significance is still unclear. METHODOLOGY: Fifty-nine serum samples from patients with ulcerative colitis, 17 with Crohn's disease, 25 with irritable bowel syndrome, and 86 healthy persons were studied. Sera were analyzed for the presence of ANCA by indirect immunofluorescence, and enzyme-linked immunosorbent assay for specific ANCA using different antigens was performed. RESULTS: ANCA were detected in 29 of 59 (49%) patients with ulcerative colitis, 4 of 17 (24%) patients with Crohn's disease, and in 4 of 111 (4%) controls. The immunofluorescence staining was mostly perinuclear (pANCA). There was no correlation between ANCA and the duration or extent of the inflammatory bowel disease. In specific enzyme-linked immunosorbent assays, only 14 sera elicited binding above the normal range. CONCLUSIONS: Although the prevalence of ulcerative colitis and Crohn's disease in Estonia is much lower than in European countries, there seem to be no differences in the presence of ANCA.     

Bone assessment in patients with ileal pouch-anal anastomosis for inflammatory bowel disease

BACKGROUND: Patients with ulcerative colitis are at risk of low bone mineral density (BMD). Proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis diminishes the risk of bone disease. The aims of this study were to assess the mechanism of low BMD and to measure bone density changes after IPAA. METHODS: Twenty patients with IPAA for ulcerative colitis, of mean(s.d.) age 38(9) (range 21-58) years, had measurements of lumbar spine and femoral neck BMD by dual energy X-ray absorptiometry, a mean(s.d.) 28(23) (range 3-84) months after proctocolectomy. Serum levels of calcium, phosphate, parathyroid hormone, osteocalcin and 25-hydroxy vitamin D were determined. Fifteen patients were followed for 28(12) (range 8-50) months. RESULTS: At baseline, six patients had spine BMD more than two standard deviations below the normal value, and three had vertebral crush fractures. Mean vitamin D values were normal and no patient had osteomalacia. BMD increased with time elapsed since IPAA (spine: r = 0.71, P = 0.005). During follow-up, mean(s.d.) changes in bone density were +2.3(3.8) and +2.1(5.6) per cent per year at the spine and femoral neck respectively. CONCLUSION: These results suggest that in patients with IPAA for ulcerative colitis, low BMD is not associated with vitamin D malabsorption and may be reversible after surgery.     

Growth of prepubertal children with inflammatory bowel disease

BACKGROUND: Growth retardation has been reported in children with chronic inflammatory bowel disease, especially in those with Crohn's disease. Most of these studies concern adolescent patients. METHODS: The growth of 47 prepubertal children (20 boys and 27 girls, mean age at diagnosis 7 years) with inflammatory bowel disease was studied at Tampere University Hospital, Department of Paediatrics. The mean height and height velocity standard deviation scores were calculated at diagnosis and, after that, yearly. The cumulative doses of oral and rectal prednisone per year were calculated. The severity of the disease was scored. The statistical analysis was carried out using the analysis of variance for repeated measurements. RESULTS: During the year preceding the diagnosis, children with inflammatory bowel disease had grown more slowly than their healthy peers. At diagnosis, they were slightly shorter as a group than are healthy children. During treatment and follow-up the mean height velocity of children with inflammatory bowel disease increased (change in the mean height velocity standard deviation scores from -0.84 to +1.08), normalizing the mean heights of these children compared with those of their healthy peers (change in the mean height standard deviation scores from -0.32 to +0.05). In the analysis of covariance, the poorest growth was seen in children with Crohn's disease, scored as severe, and the best growth in children with mild ulcerative colitis. No difference was seen in groups with or without prednisone treatment. CONCLUSIONS: Growth retardation is an important sign of chronic inflammatory bowel disease in prepubertal as well as adolescent children. During treatment, increasing growth velocity brings these children as a group to normal heights for age and sex.     

Antibodies in patients with inflammatory bowel disease and the apparent influence of medications

Patients with inflammatory bowel disease (IBD) are known to have increased antibodies to several food and bacterial antigens. To assess selected isotype contributions in greater detail, we examined the concentrations of IgA, IgG, IgE, and IgG4 antibodies to five selected antigens, two of bacterial and three of food origin. Thirty patients with IBD and thirty matched healthy controls were studied. Most antibodies were increased in IBD patients compared to controls. Statistically significant increases were more frequent in Crohn's disease (CD) than in ulcerative colitis (UC). An unexpected finding was that IBD patients treated with sulfasalazine had statistically higher levels of most IgA antibodies than healthy controls, while steroid treated patients had lower levels. These findings suggest differing effects on the immune systems of IBD patients by each of these commonly used drugs.     

Safety of azathioprine and 6-mercaptopurine in pediatric patients with inflammatory bowel disease

BACKGROUND & AIMS: Azathioprine (AZA) and 6-mercaptopurine (6-MP) are used in pediatric patients with ulcerative colitis and Crohn's disease to reduce disease activity, maintain remission, prevent relapse, and lower corticosteroid dosage, but their long-term side effects remain to be studied. The aim of this study was to analyze the safety of AZA and 6-MP and steroid reduction in this age group. METHODS: The investigators' database identified 118 patients who received either drug; 23 were excluded (single visit, noncompliance, or therapy < 1 week), leaving 95 patients, with a mean (+/-SD) age of 14.2 +/- 4.4 years. Medical files were reviewed for adverse side effects: fever, pancreatitis, infections, gastrointestinal intolerance, aminotransferase level increase, leukopenia, and thrombocytopenia. Prednisone doses before and after immunomodulatory therapy were compared. RESULTS: AZA or 6-MP was tolerated in 51 of 95 patients (54%) without adverse reaction; 27 of 95 (28%) experienced side effects that responded to dose reduction (23 patients) or spontaneously (4 patients), most commonly increased aminotransferase level (13.7%). Cessation of therapy was needed in 17 of 95 patients (18%), including recurrent fever (4), pancreatitis (4), gastrointestinal intolerance (4), and recurrent infections (3). Mean prednisone dose decreased from 24.3 to 8.6 mg/day. CONCLUSIONS: AZA and 6-MP were well tolerated in 82% of patients; of these, prednisone reduction occurred in 87%. However, 18% required discontinuation because of hypersensitivity or infectious side effects.     

Combat exposure and adult psychosocial adjustment among U.S. Army veterans serving in Vietnam, 1965–1971.

This study investigated the relationship between combat exposure and adult antisocial behavior in a sample of 2,490 male Army veterans of the Vietnam War who completed questionnaires about their psychological functioning. After adjustment for history of childhood behavior problems, posttraumatic stress disorder diagnosis, and demographic and military characteristics, it was found that veterans who experienced high and very high levels of combat were twice as likely to report adult antisocial behavior as veterans with no or low levels of combat and were also more likely to meet criteria for antisocial personality disorder. The results indicate that exposure to traumatic events during late adolescence or early adulthood is associated with multiple adult adjustment problems in vocational, interpersonal, and societal functioning. Treatment focusing on the effects of the trauma is likely to be necessary but not sufficient for improving affected veterans' behavior.

Carcinoid tumour complicating inflammatory bowel disease. A study of two cases with review of the literature

Two cases of carcinoid tumour complicating inflammatory bowel disease (IBD) are presented. Both tumours were located in the appendiceal tip. The first case occurred in a man with Crohn's disease (CD), and the second one in a woman suffering from ulcerative colitis (UC). Histochemical and immunohistochemical studies were not allowed on case 1 because the tumour was not still present on serial sections of the appendix. On case 2, tumour cells were not reactive with Grimelius and Masson-Fontana stainings, but were strongly stained with anti-keratin and anti-chromogranin monoclonal antibodies (MAb), and faintly expressed neuron specific enolase (NSE), and Leu-7. Both cases occurred in inflammatory or damaged mucosa which exhibited Paneth cell metaplasia and hyperplasia and areas indefinite for dysplasia. Along with these lesions, hyperplasia of enteroendocrine cells was pointed out in the neighbouring appendiceal and colonic mucosa by means of anti-chromogranin MAb. These data suggest that the association of carcinoid tumour with IBD, albeit rare, is not coincidental and is the result of hyperplastic and dysplastic troubles that may involve enteroendocrine cells as well as such other derivatives of digestive stem cells as columnar cells, goblet cells and Paneth cells.     

Anti-cardiolipin and anti-beta2-glycoprotein I antibodies in patients with inflammatory bowel disease

Patients with inflammatory bowel disease (IBD) frequently suffer from thromboembolic events. Anti-cardiolipin (aCL) antibodies have been shown to be associated with thrombosis. Recently, the antibodies against the anti-cardiolipin cofactor beta2-glycoprotein I (a(beta2)GPI) have been found with higher specificity for thrombosis. The presence of these antibodies was assessed in 128 patients with IBD [83 with ulcerative colitis (UC) and 45 with Crohn's disease (CD)] and 100 healthy controls (blood donors). Patients with UC and CD had a significantly higher prevalence of aCL (18.1% and 15.6%, respectively) than healthy controls (HC) (3%). Eleven IBD patients (8.6%) but no HC had a(beta2)GPI. None of the IBD patients with a history of thrombosis had aCL and only one of them (a UC patient with deep vein thrombosis of the right leg) had a high titer of IgG a(beta2)GPI. In conclusion, these data show that both aCL and a(beta2)GPI are significantly associated with IBD but further studies are needed to determine the significance of our findings.     

Laparoscopic-assisted bowel resections in inflammatory bowel disease: state of the art

The objectives of this paper are to review the rational, the present results and future of laparoscopic-assisted bowel surgery in patients with inflammatory bowel disease (IBD). Only a few centres in the world report on laparoscopic bowel resection in IBD that include stoma surgery, ileocolic resection, left, right and (sub)total colectomy for Crohn's disease, and subtotal or restorative total proctocolectomy (ileal pouch anal procedures). The combined series report conversion rates between 2.5% and 22.2%. Ileocolic resection, stoma creation, stricturoplasty and segmental small bowel resection are associated with an acceptable length of surgery, but laparoscopic(-assisted) total colectomy or restorative proctocolectomy still demand up to 4-6 hours of operative time. The few randomised studies addressing laparoscopic-assisted (segmental) bowel surgery versus conventional surgery demonstrated significantly less pain, a quicker return to self-care and a shorter hospital stay. The results of the series reporting on laparoscopic-assisted (ileo)colectomy in IBD are similar to those from these randomised studies. Laparoscopic-assisted subtotal colectomy and restorative proctocolectomy have no benefit compared with conventional surgery other than superior cosmesis. Morbidity of laparoscopic (ileo)colectomy in IBD is low, that of laparoscopic-assisted subtotal colectomy and restorative proctocolectomy remains to be seen. The various laparoscopic bowel resections done in IBD are all feasible. The first series describing laparoscopic surgery for IBD indicate that laparoscopic-assisted segmental (ileo)colectomy is safe and is the preferred approach provided it is done in a centre specialised in the treatment of IBD and by skilled laparoscopic surgeons beyond the learning curve. Until now, laparoscopic-assisted subtotal colectomy and restorative proctocolectomy do not have the same short-term benefits as seen in other laparoscopic colorectal procedures. Patients with inflammatory bowel disease (IBD) have a high life-time risk of having abdominal surgery and reoperations. The proposed advantages of laparoscopic surgery in this group of young patients might be higher than in patients with other colorectal diseases. Minimal physiologic insult in patients who already are under significant physiologic stress, less adhesion formation and superior cosmesis are important benefits over time. In a time where patient's demands will increase, the future of laparoscopic colonic surgery in IBD looks assured.     

Detection of pro- and anti-inflammatory cytokines in stools of patients with inflammatory bowel disease

Astroglial cells protect neurons against oxidative damage. The antioxidant glutathione plays a pivotal role in the neuroprotective action of astroglial cells which is impaired following loss of glutathione. Anethole dithiolethione (ADT), a sulfur-containing compound which is used in humans as a secretagogue, increases glutathione levels in cultured astroglial cells under "physiological" conditions and is thought thereby to protect against oxidative damage. Presently, we report the effect of ADT (3-100 microM) on glutathione content of and efflux from rat primary astroglia-rich cultures under "pathological" conditions, i.e., extended deprivation of glucose and amino acids. Although cellular viability was not affected significantly, starvation of these cultures for 24 h in a bicarbonate buffer lacking glucose and amino acids led to a decrease in glutathione and protein content of approximately 43% and 40%, respectively. Although no effect on the protein loss occurred, the presence of ADT during starvation counteracted the starvation-induced loss of intracellular glutathione in a concentration-dependent way. At a concentration of 100 microM ADT even a significant increase in astroglial glutathione content was noted after 24 h of starvation. Alike intracellular glutathione levels, the amount of glutathione found in the buffer was elevated substantially if ADT was present during starvation. This ADT-mediated, apparent increase in glutathione efflux was additive to the stimulatory effect on extracellular glutathione levels of acivicin (100 microM), an inhibitor of extracellular enzymatic glutathione breakdown. However, the ADT-induced elevation of both intra- and extracellular glutathione content during starvation was prevented completely by coincubation with buthionine sulfoximine (10 microM), an inhibitor of glutathione synthesis. These results demonstrate that, most likely through stimulation of glutathione synthesis, ADT enables astroglial cells to maintain higher intra- and extracellular levels of glutathione under adverse conditions. Considering the lowered glutathione levels in neurodegenerative syndromes, we conclude that further evaluation of the therapeutic potential of the compound is warranted.     

The role of complementary medicine in European and Asian patients with inflammatory bowel disease

A 20-year-old Japanese woman (Case 1) and a 70-year-old Japanese man (Case 2) consulted us with slight fever and disseminated erythematous papules. Examinations revealed that the first case was a skin eruption due to trimethoprim itself and the second was due to both trimethoprim and sulphamethoxazole. To our knowledge, our Case 1 is the first reported case with an erythematous papular type skin eruption caused by trimethoprim itself, and our Case 2 is the first case of a skin eruption in reaction to both trimethoprim and sulphamethoxazole.
