Dataset Information

Severity of non-alcoholic fatty liver disease is a risk factor for developing hypertension from prehypertension.

ABSTRACT:

Background

There is little published evidence about the role of non-alcoholic fatty liver disease (NAFLD) in the progression from prehypertension to hypertension. This study was conducted to investigate the association of NAFLD and its severity with the risk of hypertension developing from prehypertension.

Methods

The study cohort comprised 25,433 participants from the Kailuan study with prehypertension at baseline; those with excessive alcohol consumption and other liver diseases were excluded. NAFLD was diagnosed by ultrasonography and stratified as mild, moderate, or severe. Univariable and multivariable Cox proportional hazard regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) of incident hypertension according to the presence and 3 categories of severity of NAFLD.

Results

During a median of 12.6 years of follow-up, 10,638 participants progressed to hypertension from prehypertension. After adjusting for multiple risk factors, patients with prehypertension and NAFLD had a 15% higher risk of incident hypertension than those without NAFLD (HR = 1.15, 95% CI 1.10-1.21). Moreover, the severity of NAFLD was associated with the incidence of hypertension, which was higher in patients with more severe NAFLD (HR = 1.15 [95% CI 1.10-1.21] in the mild NAFLD group; HR = 1.15 [95% CI 1.07-1.24] in the moderate NAFLD group; and HR = 1.20 [95% CI 1.03-1.41] in the severe NAFLD group). Subgroup analysis indicated that age and baseline systolic blood pressure may modify this association.

Conclusions

NAFLD is an independent risk factor for hypertension in patients with prehypertension. The risk of incident hypertension increases with the severity of NAFLD.

Project description:Helicobacter pylori infection has been investigated as a potential risk factor for non-alcoholic fatty liver disease (NAFLD). Some studies suggest a possible link between the two conditions. The purpose of this study is to study the relationship between H. pylori infection and NAFLD in pediatrics and its relation to NAFLD grades. A case-control study to identify predictors of NAFLD and a comparative cross-sectional approach to determine factors affecting NAFLD grades were adopted. One hundred NAFLD children (ultrasound-based) and a control group of 100 non-NAFLD children were recruited. Both groups were evaluated by detecting H. pylori stool antigen. Immunoglobulin G antibodies to Cag A (cytotoxin-associated gene A), Vac A (vacuolating cytotoxin A), Gro EL (chaperonin Gro EL), HCPC (Helicobacter cysteine-rich protein C), and Ure A (Urease subunit A) were assessed in the serum of those with positive stool antigen. H. pylori infection was significantly higher in NAFLD children compared to the control group (64% versus 25%, p-value < .001). (NAFLD children showed higher Cag A and Vac A positivity (34, 10%) versus (2%, 0%) in the control group, respectively, p-value < .001). The regression model showed that H. pylori positivity (OR (odds ratio) = 5.021, 95% CI (confidence interval): 1.105-22.815), homeostatic model assessment of insulin resistance (Homa IR) (OR = 18.840, 95% CI: 3.998-88.789), waist percentile (OR = 1.184, 95% CI: 1.044-1.344), and triglycerides (OR = 1.029, 95% CI: 1.012-1.047) were predictors for NAFLD. Cag A positivity (OR = 2.740, 95% CI: 1.013-7.411) was associated with higher NAFLD grade (grade 2 fatty liver).ConclusionsH. pylori infection could increase the risk of NAFLD in children. Triglycerides, waist circumference, and Homa IR are significant independent predictors of NAFLD.What is known• NAFLD has become one of the most common liver diseases among children because of the increased prevalence of pediatric obesity. • Dyslipidemia and insulin resistance play a central role in NAFLD pathogenesis. • NAFLD could be explained by the multiple-hit hypothesis. The gut microbiota is an important factor in this hypothesis (gut liver axis).What is new• Helicobacter pylori infection could increase the risk of NAFLD in children. • H. pylori Cytotoxin-associated gene A (Cag A) positivity is associated with higher NAFLD grade.
