rome_iv_reflux_hypersensitivity: Rome IV Diagnostic Criteria for Reflux Hypersensitivity

Description

Evaluates the **Rome IV criteria** for diagnosing **Reflux Hypersensitivity**. This disorder is characterized by retrosternal symptoms (heartburn or chest pain) caused by physiological amounts of reflux (non-acid or acid) in patients who are refractory to proton pump inhibitor (PPI) therapy and lack endoscopic evidence of erosive esophagitis.

Usage

                                 reflux_excluded, symptoms_refractory_to_ppis,
                                 symptoms_triggered_by_reflux,
                                 symptoms_not_associated_with_major_motility,

                                 symptoms_active_last_3_months)

Value

A list containing:

Diagnosis

"Criteria Met for Reflux Hypersensitivity" or "Criteria Not Met".

Arguments

retrosternal_symptoms_bothersome

Numeric (0 or 1). Presence of bothersome retrosternal symptoms (heartburn or chest pain). (1 = Yes).

normal_egd

Numeric (0 or 1). Normal Esophagogastroduodenoscopy (EGD) (i.e., no erosive esophagitis). (1 = Yes).

reflux_excluded

Numeric (0 or 1). Absence of pathological reflux (negative symptom association probability or acid exposure time). (1 = Yes).

symptoms_refractory_to_ppis

Numeric (0 or 1). Refractory to optimized antisecretory therapy (e.g., maximal PPIs). (1 = Yes).

symptoms_triggered_by_reflux

Numeric (0 or 1). Symptoms are triggered by reflux events (positive symptom association probability or symptom index on reflux monitoring). (1 = Yes).

symptoms_not_associated_with_major_motility

Numeric (0 or 1). Absence of major esophageal motor disorders (e.g., achalasia, spasm). (1 = Yes).

symptom_onset_ge_6_months

Numeric (0 or 1). Did symptom onset occur at least **6 months ago**? (1 = Yes).

symptoms_active_last_3_months

Numeric (0 or 1). Have symptoms been active for the last **3 months**? (1 = Yes).

Examples

# Example 1: Diagnosis Met
# All criteria met (bothersome symptoms, normal EGD, triggered by normal reflux,
#PPI refractory, no motility issues, chronic duration)

# Example 2: Not Met (Pathological Reflux Present)
# Reflux monitoring shows excessive acid exposure time (0 for reflux_excluded)
