5-Aminosalicylic acid suppositories in the management of ulcerative colitis.

5-aminosalicylic acid (5-ASA) suppositories have been used in the author's out-patient clinic in Bologna for the treatment of distal ulcerative colitis (UC). One hundred fifty-six patients with mild or moderate attacks of UC were treated using different protocols for controlling active disease. Improvement was observed in 88.5 percent of the therapeutic cycles after one month. A small preliminary maintenance study using only 400-mg suppositories of 5-ASA twice a day for 6 or 12 months showed a remission percentage similar to salicylazosulfapyridine (SASP).

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).

Oesophageal function before, during, and after healing of erosive oesophagitis.

In order to investigate the relationship between oesophageal motor abnormalities and oesophagitis, we carried out four hour studies of oesophageal motility and 24 hour pH measurements in fasting and fed conditions in eight patients before, during (pH only), and after medical healing of erosive oesophagitis. Gastrooesophageal acid reflux decreased (ns) during the treatment, but tended to return to basal values at the end. Oesophageal body motility was unchanged after healing, while the lower oesophageal sphincter basal tone was significantly increased at the end of the study in the postcibal period. The results suggest that the impairment of the sphincter tone in reflux oesophagitis is secondary to the presence of the oesophageal lesions. Macroscopic healing is not paralleled by improved major pathogenic factors of the disease, however--that is, acid reflux and oesophageal body motility.

Evaluation of oral administration of folic and folinic acid to prevent folate deficiency in patients with inflammatory bowel disease treated with salicylazosulfapyridine.

In order to evaluate the efficacy of oral administration of a pharmacological dose of folic or of folinic acid to prevent the folate deficiency in patients with inflammatory bowel disease (IBD) treated with salicylazosulfapyridine (SASP) (1g twice daily at meal times), two groups of 15 patients with IBD received 15 mg/day of folic or folinic acid for one month. In both the groups there were ten patients affected by Crohn's disease and five patients affected by ulcerative colitis. Before starting the treatment, the plasma folate and the red blood cell (RBC) folate concentrations did not statistically differ between the two groups. After one month the mean increase in RBC folate concentration was significantly greater after folinic therapy then after folic acid therapy (910 +/- 383 versus 570 +/- 212 ng/ml; p less than 0.01), while no difference was observed in the mean increase of plasma folate level (19.8 +/- 6.6 versus 18.5 +/- 5.0 ng/ml). It was concluded that: a) both folic and folinic acid could restore and enlarge the body stores of folate in patients with IBD treated with SASP, when administered at the dose of 15 mg daily for one month; b) folinic acid seems to be more efficient in enlarging the body stores of the vitamin than folic acid.

Efficacy of addition of exogenous lactase to milk in adult lactase deficiency.

The efficacy of lactase by Kluyveromyces lactis in hydrolyzing milk lactose and reducing milk intolerance symptoms was tested in 52 proved lactose malabsorbers. The enzyme was added to milk administered to the patients, and H2 breath excretion (as an index of carbohydrate malabsorption), was determined by gas chromatograph technique, and milk intolerance symptoms were recorded. H2 mean excretion was 78.3 +/- 5.49 ppm after administration of intact whole milk 500 ml (test A), 43.5 +/- 4.99 ppm when lactase 2000 U was added to milk 500 ml immediately before administration (test B); 36.7 +/- 5.01 ppm when milk 500 ml was incubated for 12 h with lactase 1000 U (test C), and 29.7 +/- 4.35 ppm when the incubation was prolonged for 24 h (test D). Symptoms score was: test A = 5.85 +/- 0.56, test B = 3.71 +/- 0.45, test C = 2.77 +/- 0.63, test D = 1.7 +/- 0.68. A correlation index of r = 0.44 (p less than 0.01) was obtained between reduction in H2 mean excretion and reduction in symptoms score of a single individual. The addition of this lactase to milk seems to be effective in correcting lactose malabsorption, thus representing a convenient approach in milk intolerance.

Lactose malabsorption in adult patients with Crohn's disease.

In order to evaluate, in adult patients with Crohn's disease (CD), the prevalence of lactose malabsorption and intolerance, and the percentage who can tolerate a physiologic amount of milk in their diet, we tested 37 patients with CD (19 with intestinal resection, and 18 without) and 67 healthy controls (C) with the H2-breath test after they had ingested increasing loads of lactose as 10% solution (12.5 g, 25 g, and 50 g). Patients with malabsorption after the 12.5-g dose were tested further with 250 ml of milk. In the total group of patients and in the subgroup of those with resection, the prevalence of malabsorption was higher than in controls at all lactose loads; in patients who had not undergone resection, no significant difference was observed with the 12.5-g dose. Eleven of 18 patients who were malabsorbers with the 12.5-g dose had malabsorption also with 250 ml milk; however, only three of them (8% of the total group) experienced symptoms of intolerance. We conclude that, in adult patients with CD, 1) the prevalence of lactose malabsorption is increased, 2) in patients who have undergone intestinal resection, malabsorption occurs at a lower dose of the sugar than in patients who did not, and 3) since only 8% of patients experienced symptoms of intolerance after the ingestion of milk 250 ml, this amount can be empirically inserted in the daily diet of an adult with CD.

Urinary zinc excretion in Crohn's disease.

In order to study the reliability of urinary zinc levels as an index of zinc metabolism and status in Crohn's disease, we evaluated plasma and urinary zinc concentrations, urinary 3-methylhistidine excretion, and Crohn's disease activity index (CDAI) in 42 patients affected by Crohn's disease. Plasma zinc correlated directly with albuminemia (P = 0.01) and inversely with CDAI (P = 0.001). Urinary zinc excretion correlated with urinary 3-methylhistidine (P = 0.001) and plasma zinc levels (P = 0.01), and inversely with CDAI (P = 0.05). However, from multiple regression analysis, it was found that zincemia is influenced by CDAI and not by albumin, whereas zincuria is related to urinary 3-methylhistidine and plasma zinc, and not to CDAI. Our conclusion is that, in Crohn's disease, zincuria can be an index of zinc status when used together with measurements of lean body mass and turnover and factors influencing plasma ultrafiltrable zinc fraction.

Efficacy of 5-aminosalicylic acid enemas versus hydrocortisone enemas in ulcerative colitis.

A controlled trial has been carried out in order to compare the efficacy of enemas containing a high dosage of 5-ASA (4 g) versus enemas containing hydrocortisone 100 mg. The trial was conducted on 86 patients, 44 of whom received 5-ASA and 42 received hydrocortisone. The results were favorable in terms of clinical, sigmoidoscopic, and histologic criteria for 5-ASA treatment. Other aspects have been investigated, such as retrograde spread of enemas which have been shown to reach the left colon. No nephrotoxicity was detected. The long term experience confirmed the preliminary positive results.

Candida albicans infection of gastric ulcer frequency and correlation with medical treatment. Results of a multicenter study.

This paper reports the results of a multicenter prospective study of 188 consecutive patients affected by gastric ulcer, verified by endoscopy, in whom the frequency of a mycotic infection of the lesion was evaluated as well as the eventual influence of such pathology on the efficiency of medical treatment, the healing rate, and the healing time. A mycotic infection, defined as penetration of the periulcerous mucosa by the fungi, was found in only 13 patients (6.9%). No significant differences were found in the healing rate and healing time among these patients treated with H2-receptor antagonists and a control group of 43 matched gastric ulcer patients treated in the same period with the same therapy. It would appear from the data that mycotic infections of the gastric ulcer do not modify the efficiency of medical treatment.

Oesophageal motor events at the occurrence of acid reflux and during endogenous acid exposure in healthy subjects and in patients with oesophagitis.

In order to assess the oesophageal motor events associated with the occurrence of gastro-oesophageal acid reflux and those during endogenous acid exposure, we studied six healthy subjects and nine patients with symptoms and lesions of reflux oesophagitis. In the case of each subject simultaneous pressure and pH measurements of the distal oesophagus were taken both in fasting conditions and after a standardised balanced meal. Reflux episodes occurred in the absence of a lower oesophageal sphincter relaxation (34.3%, 17.7%) or in the presence of a relaxation associated (34.2%, 30.8%) or unassociated (31.5%, 51.5%) with a peristaltic sequence, in the controls and patients respectively. No significant differences were found between the two groups. During endogenous acid perfusion the distal oesophagus showed mainly a peristaltic motor activity, but the mean hourly number of peristaltic sequences was significantly lower in the patients than in the controls (33.5 +/- 27.2 vs 81.5 +/- 3.2, p less than 0.01). Our results show that the mechanisms of reflux are similar in controls and in patients, while the peristaltic frequency is reduced in the latter. This motor failure may be responsible for the increased reflux duration observed in patients with oesophagitis.

Depression and gastrointestinal illness: the joint use of biological and clinical criteria.

Occurrence and characteristics of depression were investigated in 37 consecutive patients suffering from gastrointestinal illness. More than 40% of patients with an organic digestive disease and about a quarter of those with functional gastroenterological complaints were found to suffer from a major depressive disorder according to DSM-III criteria. The dexamethasone suppression test--a laboratory marker of the endogenous depressive state--supported clinical diagnosis in several cases, yet its routine use to screen depression is not warranted because of its poor specificity. The results should alert the physician to include clinical and biological criteria for depression in the diagnostic work-up for gastrointestinal illness.

Colonic involvement in adult patients with Henoch-Schoenlein purpura.

Henoch-Schoenlein purpura is a haemorrhagic syndrome, rare in the adult but well known in paediatric pathology. The clinical manifestations are usually: arthralgia, skin rash, renal and gastrointestinal involvement. Although the small bowel is more frequently involved, cases of oesophageal, gastroduodenal and colo-rectal localization have been rarely reported. We describe endoscopic features of two cases of Henoch-Schoenlein syndrome with extensive colonic involvement. No previous endoscopic documentation of this localization has been reported in our available literature.
