Clinical practice guidelines on the diagnosis and treatment of gastroesophageal reflux disease (GERD)

In the last two decades gastroesophageal reflux disease (GERD), initially thought to be a disease only common  in the West, is described  increasingly in Asia, including the Philippines. A recent local report indicated that the prevalence of erosive esophagitis (EE), a common complication of GERD, has more than doubled, i.e., 2.9% to  6.3%,  between the two time periods of 1994-1997 and 2000-2003, respectively. GERD causes recurrent annoying symptoms which are common  reasons  for  clinic  visits  and consultations thus, it is the objective of these guidelines to provide both primary care physicians  (PCPs) and specialists a current, evidence-based, country-specific recommendations for the optimal management  of  GERD.  These  guidelines  are  intended   to   empower   PCPs   to   make   a   clinic-based diagnosis of GERD, to start an empiric acid-suppressive therapy in the appropriate patient,and direct them to select which GERD patient may need to undergo investigations to ascertain further the diagnosis of GERD or to assess outcomes of therapy. We acknowledge that studies published in the future may influence the impact on our confidence on the recommendations enumerated in  these guidelines thus, we commit to update this document when it is deemed appropriate.

Erosive esophagitis in the Philippines: a comparison between two time periods.

BACKGROUND: In Asia, the incidence of gastroesophageal reflux disease diagnosed through endoscopy has increased from 3-9% to 14-16% in the last decade. The aim of this study was to determine the prevalence of erosive esophagitis (EE) over a span of 10 years in a tertiary care facility in the Philippines. METHODS: All patients diagnosed with EE from 1994 to 1997 (period A) and from 2000 to 2003 (period B) were included in the study. The modified Savary-Miller and Los Angeles classifications were used to grade EE for periods A and B, respectively. RESULTS: A total of 15 981 upper endoscopies were evaluated for this study. There was no significant difference in the male: female ratio (period A 1.43:1 vs period B 1.25:1, P = 0.459) and in the mean age of patients with EE (period A 46.4 vs period B 47.5, P = 0.395). The prevalence of EE was significantly higher (P < 0.0001) in period B (6.3%) as compared to period A (2.9%). However, despite a higher prevalence, more patients had mild esophagitis in period B as compared to period A. Conversely, there were more patients with esophageal ulcers (18.6%vs 5.9%, P < 0.001), esophageal strictures (2.3%vs 0%, P = 0.003), and hiatal hernia (15.8%vs 7.5%, P = 0.001) in period A. The presence of concomitant Barrett's esophagus was not significantly different between the two time periods (period A 3.2%vs period B 5%, P = 0.367). CONCLUSIONS: The prevalence of EE was higher in 2000-2003 than in 1994-1997, although the complications associated with the disease diminished. The prevalence of concomitant Barrett's esophagus remained stable.

Changing trends in peptic ulcer prevalence in a tertiary care setting in the Philippines: a seven-year study.

BACKGROUND AND AIMS: The declining global prevalence of peptic ulcer disease (PUD) might be because of the decreasing prevalence of Helicobacter pylori (Hp) infection. The aims of the present study were to determine the prevalence of PUD during a 7-year period and to investigate its relationship with the prevalence of Hp infection during the same period. METHODS: All upper gastrointestinal endoscopies carried out at Santo Tomas Hospital in Manila from January 1996 to December 2002 were evaluated. Endoscopies reporting gastric ulcers (GU) and duodenal ulcers (DU) with Hp status were analyzed. RESULTS: A total of 15 341 endoscopies were evaluated. Overall, 2600 (16.95%) GU and 1575 (10.27%) DU were identified. There was a decreasing trend in the prevalence of GU (P < 0.0001) and DU (P < 0.0001) during the study period. Overall PUD prevalence declined from 35.87% in 1996 to 18.80% in 2002. This decline was seen for both GU and DU (20.05 vs 14.34%, and 15.83 vs 7.02%, respectively). The prevalence of Hp infection decreased significantly from 1996 to 2002 for both GU and DU (68.13 vs 33.48%, P < 0.0001; and 76.67 vs 36.50%, P < 0.0001, respectively). The decrease in Hp prevalence was significantly related to the decrease in ulcer prevalence (r = 0.97, P = 0.0004 for GU; r = 0.89, P = 0.0079 for DU; and r = 0.92, P = 0.0035 for all PUD). The prevalence of bleeding secondary to PUD remained stable during the 7-year period (P = 0.87). CONCLUSIONS: During the 7-year period, there was a significant decline in the prevalence of PUD. This decline in PUD prevalence was associated with a corresponding decrease in Hp prevalence.
