T. Poynard et al., RELAPSE RATE OF PATIENTS AFTER HEALING OF ESOPHAGITIS - A PROSPECTIVE-STUDY OF ALGINATE AS SELF-CARE TREATMENT FOR 6 MONTHS, Alimentary pharmacology & therapeutics, 7(4), 1993, pp. 385-392
In order to estimate the rate of symptomatic relapse and to identify f
actors associated with this relapse, 1030 patients were included in a
multicentre study. All patients included had clinically and endoscopic
ally healed oesophagitis (grade I (erosion, 57%), grade II (confluent
erosion, 33%) or grade III (circular erosion, 9%)) after treatment wit
h an H-2-blocker or omeprazole. Patients were given conservative advic
e and were told to take sodium alginate only in response to pain. Rela
pse was defined as pain justifying more than eight sodium alginate sac
hets over 48 hours or treatment with another drug, or the need for a n
ew endoscopy. Forty risk factors were recorded initially and patients
were seen every 2 months; they filled out diary-cards describing sympt
oms and drug consumption. Data were available for 883 patients during
follow up. The cumulative percentage of patients without relapse at 6
months estimated by Kaplan Meier method was 76 +/- 2 % (mean +/- S.E.M
.). Among these patients without relapse, 95% took less than two sache
ts per day. Only two factors were identified as associated with relaps
e-the grade of oesophagitis (P < 0.007), and the occurrence of stress
during follow-up (P < 0.05). The percentage of patients free from rela
pse at six months was 85 +/- 2% in patients with grade I oesophagitis,
69 +/- 3% in patients with grade II, and 56 +/- 6% in patients with g
rade III oesophagitis (P < 0.0001).
