Helicobacter pylori infection: protective against increased interdialytic weight gain in asymptomatic hemodialysis...

Infection with Helicobacter pylori, which induces persistent and uncontrolled gastric inflammation leading to decreased appetite, might be protective against obesity. There is a close relationship between interdialytic weight gain (IDWG) and nutritional parameters, confirming the role of IDWG as a marker of calorie and protein intake in hemodialysis (HD) patients. Hypothesis of the present study was that infection with H pylori in subjects with uremia might cause inflammation, diminished appetite, anorexia, and decreased IDWG.

A cross-sectional study was conducted.

This trial involved HD patients from a state hospital.

Demographic, laboratory, and clinical parameters were collected. All patients were clinically stable and euvolemic and their average IDWG percent was calculated. Malnutrition inflammation score, spKt/V, and normalized protein equivalent of total nitrogen appearance were determined. Patients were asked to rate their appetite status from 1 to 5 on a Likert scale (very good, good, fair, poor, and very poor appetite, respectively). An H pylori infection was detected by the H pylori stool antigen (HpSA) in all the patients.

HpSA was positive in 18 (30%) patients. None of the demographic and laboratory parameters differed between patients infected with HpSA and the noninfected patients. Stepwise linear regression analysis of independent factors related with IDWG% revealed that daily urine output (β = -0.432, P < .0001), serum phosphorus (β = +0.343, P = .004), and hemoglobin (β = +0.358, P = .003) were related with IDWG%.

Infection with H pylori is not related with IDWG% and nutritional parameters in HD patients.
