Nonsteroidal antiinflammatory drugs for cancer pain: comparison between misoprostol and ranitidine in prevention of upper gastrointestinal damage.

PURPOSE: The prophylactic strategy of nonsteroidal antiinflammatory drug (NSAID)-induced upper gastrointestinal (UGI) damage has largely been studied in arthritic patients, but not in cancer patients. The efficacy of misoprostol and ranitidine in the prevention of gastroduodenal damage in patients taking diclofenac for their cancer pain has been compared in this study. PATIENTS AND METHODS: Patients who needed high-dose (200 to 300 mg/d) diclofenac for cancer pain and without mucosal lesions at baseline gastroduodenal endoscopy were randomized to receive misoprostol (200 micrograms twice daily; M group) or ranitidine (150 mg twice daily; R group). UGI endoscopy was repeated after 4 weeks. RESULTS: Twenty-three patients treated with misoprostol and 26 treated with ranitidine concluded the study. The M group showed a significantly (P < .02) lower incidence of gastroduodenal lesions (two patients; 8.7%) than the R group (10 patients; 38.5%). Gastric ulcers occurred in one (4%) misoprostol-treated patient and in six (23%) ranitidine-treated patients. Six of seven patients with ulcers were asymptomatic. Seventy-one percent and 86% of ulcers occurred in patients older than 60 years and in those who received greater than 3.1 mg/kg of diclofenac, respectively. CONCLUSION: Misoprostol was significantly more effective than ranitidine in the prevention of gastroduodenal lesions in cancer patients receiving diclofenac.

Multicenter study of the safety/efficacy of misoprostol in the prevention and treatment of NSAID-induced gastroduodenal lesions.

Gastrointestinal symptoms and lesions are often associated with the clinical use of non-steroidal antiinflammatory drugs (NSAIDs). An open-label, single arm multicenter Italian study evaluated if misoprostol, a prostaglandin E1 analogue with gastroduodenal mucosal protective activity, was effective in the prevention and treatment of NSAID-induced gastroduodenal lesions. Patients affected by rheumatoid arthritis (RA) or osteoarthritis (OA), in treatment with NSAIDs and suffering from gastric symptoms or gastroduodenal lesions related to NSAID use, were admitted to the study. Gastrointestinal and arthritic symptoms were assessed before and after 4 weeks co-administration of an NSAID (the most frequent was diclofenac, used in 35% of the RA and in 22% of the OA patients, followed by piroxicam and tenoxicam respectively) + misoprostol (200 mcg two times daily in 58% of the cases, 200 mcg three times daily in 39%, 200 mcg four times daily in 3%). On admission and after 4 weeks of therapy a gastrointestinal endoscopy was performed to evaluate the condition of the gastroduodenal mucosa. Final results showed that: (i) NSAID-related gastric lesions were more frequent than duodenal lesions; (ii) when patients were given misoprostol and NSAIDs, 96% of them did not develop gastric lesions and 97% did not develop duodenal lesions; (iii) even when NSAID therapy was continued, gastric or duodenal lesions induced by NSAIDs healed or in any case did not worsen in 92% and 91% respectively of the cases; (iv) during the period of coadministration of NSAIDs+misoprostol, NSAID-related UGI symptoms disappeared or improved in 77% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparison of two enteric coated microsphere preparations in the treatment of pancreatic exocrine insufficiency caused by cystic fibrosis.

BACKGROUND: Pancreatic exocrine insufficiency is a common condition in patients with cystic fibrosis. Large amounts of pancreatic enzyme supplements are required to reduce malabsorption but patient compliance is not always optimal. AIMS: To compare patients' preference and the efficacy of two enteric coated microsphere preparations in patients with cystic fibrosis. PATIENTS: Patients with pancreatic exocrine insufficiency due to cystic fibrosis. METHODS: Patients were assigned to the crossover treatment with Creon or Pancrease for 1 week and then to the alternative treatment. Patients had to follow a fixed diet (at least 2 g fat/kg) and had to assume 1000 units lipase/g fat. The evaluation parameters were: patients' preference, acceptance of therapy, stool fat excretion, stool weight, gastrointestinal symptoms, and tolerance. RESULTS AND CONCLUSIONS: Of the 33/60 patients who expressed a preference for one of the two treatments, 30 preferred Creon while only 3 patients preferred Pancrease (p<0.001). No difference between the two treatments was observed regarding stool characteristics, gastrointestinal symptoms and tolerance. The mean number of capsules taken daily was reduced by 35% with Creon. The results of this study showed a preference in favour of Creon probably due to the reduction of daily capsule intake of 35%, supporting digestion as well as Pancrease.

Evaluation of the efficacy of oral cromolyn sodium or an oligoantigenic diet in children with atopic dermatitis: a multicenter study of 1085 patients.

One thousand eighty-five children with atopic dermatitis were enrolled in a multicenter study to evaluate the efficacy of 4 weeks of oral sodium cromoglycate or 4 weeks of a restricted diet. One thousand-eleven children (93%) concluded the study. At the end of the trial there was a significant improvement in skin lesions in the two groups: 61% of the patients in the sodium cromoglycate group and 69% in the restricted diet showed a significant improvement in atopic dermatitis. We concluded that, at least in our experimental design, both sodium cromoglycate and a restricted diet are equally effective in atopic dermatitis.

Efficacy of dosing and re-dosing of two oral fixed combinations of indomethacin, prochlorperazine and caffeine compared with oral sumatriptan in the acute treatment of multiple migraine attacks: a double-blind, double-dummy, randomised, parallel group, multicentre study.

AIMS AND METHODS: In this double-blind, double-dummy, randomised, parallel group, multicentre study, the efficacy of dosing and re-dosing of a fixed combination of indomethacin, prochlorperazine and caffeine (Indoprocaf) was compared with encapsulated sumatriptan in the acute treatment of two migraine attacks. Additionally, in the group taking Indoprocaf, two different oral formulations were tested: effervescent tablets and encapsulated coated tablets. RESULTS: Of 297 patients randomised (150 assigned to Indoprocaf and 147 to sumatriptan), 281 were included in the intention-to-treat efficacy analysis. The initial dosing of Indoprocaf and sumatriptan was similarly effective with pain-free rates higher than 30% (95% CI of odds-ratio: 0.57-1.28) and headache relief rates of about 60% (95% CI of odds-ratio: 0.82-1.84) with both the drugs. The efficacy of re-dosing of Indoprocaf as rescue medication was more effective than that of sumatriptan with pain-free values of 47% vs. 27% in the total attacks with a statistically significant difference in the first migraine attack in favour of Indoprocaf. The efficacy of re-dosing to treat a recurrence/relapse was very high without differences between the drugs (pain-free: 60% with Indoprocaf and 50% with sumatriptan in the total attacks). Indoprocaf and sumatriptan were well-tolerated. CONCLUSION: The study demonstrated that the efficacy of the initial dosing of Indoprocaf was not higher than that of sumatriptan, but that the strategy to use the lowest effective dose as soon as the headache occurred, followed by a second dose if the headache has not relieved or to treat a relapse, was very effective, especially with Indoprocaf.

Efficacy of a fixed combination of indomethacin, prochlorperazine, and caffeine in the treatment of episodic tension-type headache: a double-blind, randomized, nimesulide-controlled, parallel group, multicentre trial.

In this double-blind, randomized, parallel group, multicentre study the efficacy of a fixed combination of indomethacin, prochlorperazine, and caffeine (IndoProCaf) and nimesulide were compared over an 8-h period in the treatment of two consecutive episodes of tension-type headache (TTH). Both drugs were administered orally. Of 54 randomized patients, 40 were compliant to the protocol. More patients on IndoProCaf than on nimesulide were pain-free at 2 h post-dose (45% vs. 10%; P<0.05), reached a pain reduction of at least 50% at 2 (75% vs. 30%; P<0.05) and 4 h post-dose (90% vs. 58%; P<0.05), and had a statistically significant lower mean time to a 50 and 100% pain reduction in the second TTH episode. A higher percentage of patients reached a 50 or 100% pain reduction at 2 h post-dose with IndoProCaf compared with nimesulide, in two of two treated TTH episodes. A clinically and statistically significant change within each treatment group over time was found for the severity of pain, the headache intensity difference (HID), the sum of headache intensity difference (SHID), the maximum headache intensity difference (MAXHID), the headache relief (HER), the sum of total headache relief (TOTHER) and the maximum headache relief (MAXHER). In conclusion, IndoProCaf showed to be superior, but globally not statistically different from nimesulide in the treatment of episodic TTH. Both drugs were very effective and well tolerated.

[Food intolerance and irritable bowel syndrome of childhood: clinical efficacy of oral sodium cromoglycate and elimination diet]. / Intolleranza alimentare e sindrome dell'intestino irritabile del bambino: efficacia terapeutica del sodiocromoglicato orale e della dieta di esclusione.

Irritable bowel syndrome (IBS) is recognized to be a common cause of chronic diarrhea without failure to thrive in childhood. Several studies stressed the role of food intolerance as a major factor in the pathogenesis of IBS. The aim of this multicenter study was to investigate the offending role of food in IBS and to compare the therapeutic role of oral sodium cromoglycate versus elimination diet. 153 patients (mean age 4 years) with diarrhea (> 3 stools per day for four days in a week) and abdominal pain for about 10 months were enrolled in this trial. About half of the patients had a family history positive for atopy and 70% of the cases complained of intestinal symptoms after food ingestion. In 17% of the patients Skin Prick test (SPT) resulted positive to at least one food allergen and 87% of positive reactions to SPT was provoked by common foodstuffs. 87% of patients treated with elimination diet (rice, lamb, turkey, lettuce, carrots, sweet potatoes, pears, oil, tea, salt, mineral water, brown sugar) and 97% of patients treated with SCG (mean 63 mg/kg/day) for one month showed a significant improvement of intestinal symptoms. An elimination diet for several weeks can produce, beside a bad compliance (23% of patients admitted to our study didn't strictly follow diet regimen) also a nutritional deprivation. The results of this trial suggest that it's correct to investigate the role of food in children with diarrhea not due to organic diseases and diagnosed such as IBS and to use oral SCG to obtain the improvement of these symptoms.
