    Notes: Lansoprazole and omeprazole are widely used proton pump inhibitors for the management of gastro-oesophageal reflux. Normalization of oesophageal acid exposure is an important goal in the management of complicated and atypical gastro-oesophageal reflux disease.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To compare the efficacy of lansoprazole and omeprazole in the abolition of abnormal reflux as assessed by oesophageal pH monitoring.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Seventy patients with complicated or atypical gastro-oesophageal reflux disease were randomly assigned to receive 30 mg lansoprazole or 20 mg omeprazole once daily. Three to four weeks after the start of treatment, patients underwent oesophageal pH monitoring while on therapy. If the results were still abnormal, the proton pump inhibitor dosage was doubled and 24-h pH-metry was repeated after 20–30 days.〈section xml:id="abs1-4"〉〈title type="main"〉Results:Thirty-six patients were randomized to receive lansoprazole and 34 patients to receive omeprazole. Ten of the 36 (29%) patients treated with 30 mg lansoprazole once daily and 23 of the 34 (68%) patients treated with 20 mg omeprazole once daily had persistently abnormal reflux at oesophageal pH monitoring (P 〈 0.001). In all such cases, repeat pH monitoring after doubling the proton pump inhibitor dosage gave normal results.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:At the currently marketed dosages of lansoprazole and omeprazole, normalization of oesophageal acid exposure in patients is accomplished more easily with lansoprazole.

    Notes: Background : Effective intra-oesophageal acid suppression is an important therapeutic goal in complicated and atypical gastro-oesophageal reflux disease.Aim : To compare the efficacy of lansoprazole and pantoprazole in normalizing oesophageal acid exposure.Methods : Fifty patients with complicated or atypical gastro-oesophageal reflux disease were randomly assigned to receive 30 mg lansoprazole (n = 26) or 40 mg pantoprazole (n = 24) once daily. Three to four weeks after the start of treatment, patients underwent 24-h oesophageal pH monitoring whilst on therapy. If the results were improved but still abnormal, the dosage was doubled and pH monitoring was repeated. If oesophageal acid exposure was not improved, the patient was shifted to the alternative drug regimen.Results : Oesophageal acid exposure was normalized in all 26 patients treated with lansoprazole (in 35% of cases with a double daily dosage), whereas in six of the 24 (25%) patients treated with pantoprazole it was neither normalized nor lowered (P = 0.008). Accordingly, the mean percentage acid reflux time was significantly lower for the lansoprazole group (2.1) than for the pantoprazole group (5.8) (P = 0.032).Conclusions : Effective intra-oesophageal acid suppression can be accomplished more reliably with lansoprazole than with pantoprazole in patients with complicated and atypical gastro-oesophageal reflux disease.

    Notes: Effective intra-oesophageal acid suppression can be achieved with lansoprazole. The daily dosage could be influenced by the presence of hiatal hernia.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To assess the lansoprazole daily dosage required to normalize oesophageal acid exposure in patients with and without hiatal hernia.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Fifty patients with complications or atypical manifestations of gastro-oesophageal reflux disease were given lansoprazole, 30 mg once daily. Three to four weeks after the start of treatment, patients underwent oesophageal pH monitoring while on therapy. If the results were still abnormal, the lansoprazole dosage was doubled and 24-h pH-metry was repeated 20–30 days thereafter.〈section xml:id="abs1-4"〉〈title type="main"〉Results:A 30-mg daily dosage of lansoprazole normalized oesophageal acid exposure in 70% of cases, whilst a 60-mg daily dosage was necessary in the remainder: the two groups differed only in the presence of hiatal hernia (28% vs. 100%, respectively; P=0.000). Effective intra-oesophageal acid suppression was obtained in all 25 patients without hiatal hernia with the 30-mg daily dosage of lansoprazole.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Hiatal hernia is the key factor determining the lansoprazole dosage required for effective intra-oesophageal acid suppression in complicated and atypical gastro-oesophageal reflux disease. High efficacy of a 30-mg daily dosage of lansoprazole can be predicted in the absence of hiatal hernia.

    Notes: Abstract Urinary recovery and serum determination of Paba were carried out in 48 control children (C) and 53 paediatric patients with cystic fibrosis (CF) divided into three classes by age. Ninety and 120 min after the ingestion of 15 mg/kg of BT-Paba and of a standard meal, serum Paba was determined. In the same subjects the percentage Paba recovery was measured in the urine collected during an 8 h period after the same administration of BT-Paba. Correlation between urinary and serum Paba values was higher in the older children in respect to the 0–2-year-old infants. A urinary Paba test was less sensitive and specific than a serum Paba test in the evaluation of exocrine pancreatic function. The best discrimination between C and children with CF, using the maximal value of serum Paba at 90 or 120 min (peak), was obtained in the younger infants (0–2 years old). BT-Paba test with serum Paba peak determination is recommended as a substitute for the classical urinary Paba test in the evaluation of exocrine pancreatic function in paediatric patients, especially in the younger infants.
