Intended Use

HP-ONE detects the urease enzyme for the presumptive identification of Helicobacter pylori in gastric mucosal biopsies. It is intended for in-vitro diagnostic use only.

Device Story

HP-ONE is an in-vitro diagnostic test for detecting Helicobacter pylori urease enzyme in gastric mucosal biopsies. The device consists of a tray well containing a reagent with urea, hydrogen peroxide, a pH dye indicator, and an acidic buffer. During an endoscopic procedure, a biopsy specimen is placed in the tray; if H. pylori is present, the urease enzyme converts urea to ammonia, raising the pH and causing a color change in the reagent. Hydrogen peroxide acts as a preservative and accelerates the reaction via catalase activity. The test is performed by clinicians in a clinical setting. Results are interpreted visually by the healthcare provider based on color change within one hour. The test aids in the presumptive diagnosis of H. pylori gastritis, facilitating clinical decisions regarding antibiotic treatment for peptic ulcer disease and associated conditions.

Clinical Evidence

Clinical study of 117 patients with suspected peptic ulcer disease. Comparison against histological criteria (presence of H. pylori organisms). Results: 60 true positives, 5 false negatives, 52 true negatives, 0 false positives. Sensitivity: 92.3%; Specificity: 100%; Positive Predictive Value: 100%; Negative Predictive Value: 91.23%.

Technological Characteristics

In-vitro diagnostic test; liquid reagent containing urea, hydrogen peroxide, pH dye indicator, and acidic buffer. Principle: urease-catalyzed hydrolysis of urea to ammonia. Storage: 2-8°C (12-month shelf life) or 18-24°C (3-month shelf life).

Indications for Use

Indicated for the presumptive diagnosis of Helicobacter pylori gastritis in patients undergoing gastric mucosal biopsy.

Regulatory Classification

Identification

Campylobacter fetus serological reagents are devices that consist of antisera conjugated with a fluorescent dye used to identify Campylobacter fetus from clinical specimens or cultured isolates derived from clinical specimens. The identification aids in the diagnosis of diseases caused by this bacterium and provides epidemiological information on these diseases. Campylobacter fetus is a frequent cause of abortion in sheep and cattle and is sometimes responsible for endocarditis (inflammation of certain membranes of the heart) and enteritis (inflammation of the intestines) in humans.

Contact Name: Frank Carter | Address: | 200 Grandview Ave. Camp Hill, PA 17011 | |----------|----------------------------------------| | Phone #: | 717-761-1170 | | Fax #: | 717-761-0216 | #### PRODUCT NAME: HP-ONE™ 1. CLASSIFICATION NAME: Campylobacter pylori test - CODE 83LYR 2. - INTENDED USE: 3. HP-ONE detects the urease enzyme for the presumptive identification of Helicobacter pylori in gastric mucosal biopsies. It is intended for in-vitro diagnostic use only. #### SUMMARY: 3. Helicobacter pylori has now been shown to be the causative agent in most instances of acute type B gastritis (1). And, it is now known that, in the absence of aspirin, nonsteroidal anti-inflammatory drugs or hyper-secretory states, the bacteria is directly related to peptic ulcer disease such as duodenal and benign gastric ulcers (2). There is epidemiological data linking the presence of the H. pylori with gastric cancer and the lowgrade mucosal associated lymphoid tissue (MALT) lymphoma (3,4). The eradication of H. pylor gastritis by antibiotics has been shown to cure peptic ulcers and prevent recurrence (4,5). #### PRINCIPLE: 4. A gastric mucosal endoscopic biopsy is placed in the HP-ONE tray well and a reagent containing urea, hydrogen peroxide, a pH dye indicator, and an acidic buffer is placed over the biopsy specimen. A bubbling reaction occurs as catalase breaks down the peroxide. If H. pylori is present, the urease in H. pylori converts the urea to ammonia which raises the pH and changes the color of the reagent, indicating a positive test. urease (NH2)CO + H2O ------------>NH3 + HCO2 ammonia urea ## 5. STORAGE/STABILITY: The HP-ONE reagent is stable and provides accurate results for up to 12 months if refrigerated at 2-8°C. Alternatively, the reagent can be stored at room temperature (18-24°C) but the shelf life will be shortened to 3 months. If stored at room temperature, mark the date of receipt on the label and do not use beyond 3 months. Do not expose to heat or bright light. Do not use the test if the color is not a yellow or yellow-orange color or if the test is past the expiration date. Each HP-ONE reagent bottle contains an expiration date and lot number to permit tracking. HP-1 SSE rev. 7/01 p.1 {1}------------------------------------------------ - SUBSTANTIAL EQUIVALENCE AND DIFFERENCES TO PREDICATE DEVICE: The principle of HP-ONE is substantially equivalent to HP-Fast another product marketed by GI-Supply. They share the same operating principal, but HP-ONE has technical differences from HP-Fast. HP-ONE is a liquid rather than an agar gel and also has a lower pH than HP-Fast. HP-One also contains hydrogen peroxide that acts as a preservative and helps to expedite the urease reaction when H. pylori is present. #### SUMMARY OF HP-ONE PERFORMANCE CHARACTERISTICS: 7. In the clinical study of 117 patients with possible peptic ulcer disease, 65 demonstrated positive histological criteria (presence of H. pylori organisms upon staining) for Helicobacter pylori and 52 did not demonstrate the criteria. HP-ONE agreed with the positive histological diagnosis in 60 cases (92.3%) and agreed with the negative diagnosis in all 52 (100%) of the cases. This data provides a relative sensitivity of 92.3% and a relative specificity of 100%. | | True + | False + | |------------------|--------------|--------------| | HP-One Positives | 60 | 0 | | HP-One Negatives | False -<br>5 | True -<br>52 | HP-One Negatives Histology Positives = 65 Histology Negatives = 52 HP-One Sensitivity = 92.3% HP-One Specificity = 100% Positive Predictive Value = 100% Negative Predictive Value = 91.23% HP-One correctly diagnosed 66.67% of the positives within 5 minutes and 83.3% of the positives by 15 minutes. There were no false positives when diagnosed within the one-hour final reading of the test. - MEDICAL DEVICE REPORTS / ADVERSE REACTIONS ENCOUNTERED: 8. To date, no MDR's have been filed and no patient adverse reactions have been encountered.
