Increased risk of osteoporosis in patients with peptic ulcer: a follow-up study using a national sample cohort

Peptic Ulcer Disease Associated with Central Obesity

This retrospective cross-sectional study aimed to evaluate associations between peptic ulcer disease (PUD), bone mineral density, and metabolic syndrome (MetS) and its components in healthy populations. Data were collected from the health examination database of a tertiary medical center in southern Taiwan from January 2015 to December 2016. Subjects who had undergone metabolic factors assessment, upper gastrointestinal endoscopy, and dual energy X-ray absorptiometry scans were enrolled. In total, 5102 subjects were included, with mean age 52.4 ± 12.0 years. Among them, 1332 (26.1%) had PUD. Multivariate logistic regression analysis showed that age (OR 1.03, p < 0.001), male (OR 1.89, p < 0.001), diabetes (OR 1.23, p = 0.004), BMI (OR 1.03, p = 0.001), and GOT (OR 1, p = 0.003) are risk factors for PUD. Regarding MetS parameters, larger waist circumference (OR 1.26, p = 0.001) is associated with PUD, and high triglycerides (OR 1.20, 95% CI 1.01−1.43) is associated with gastric ulcer, while low HDL (OR 1.31, 95% CI 1.07−1.59) and osteoporosis (OR 1.44, 95% CI 1.08−1.91) are associated with duodenal ulcer. In conclusion, central obesity is associated with PUD in a middle-aged healthy population. Subjects with high triglycerides are prone to gastric ulcers, and those with osteoporosis and low HDL are prone to duodenal ulcers.

Establishing the Association Between Osteoporosis and Peptic Ulcer Disease: A Systematic Review

Osteoporosis is one of the most common metabolic bone diseases. Many studies were conducted to find the association between peptic ulcer disease (PUD), Helicobacter pylori infection, proton-pump inhibitor (PPI) use, and increased risk for fracture, but results remain ambiguous. We performed this systematic review to understand the association between PUD and osteoporosis. We comprehensively searched relevant articles on April 19, 2022, by exploring different databases including PubMed, PubMed Central (PMC), and Medline using relevant keywords. After applying inclusion and exclusion criteria and undergoing quality assessment, we retained 25 studies published in and after 2015. For our systematic review, we included a total of 5,600,636 participants. The studies included in our review demonstrated a significant association between PUD, H. pylori infection, and the risk of osteoporosis. Long-term PPI use was also found to be a risk factor for osteoporosis. Malabsorption of nutrients, increase in inflammatory cytokines, and alterations in hormone status were found to be the notable factors behind the association. Early management of H. pylori infection and cautious use of long-term PPIs may protect against osteoporosis. Further randomized controlled trials (RCTs) are necessary to establish a causal relationship.

Bone Fragility in Gastrointestinal Disorders

Osteoporosis is a common systemic disease of the skeleton, characterized by compromised bone mass and strength, consequently leading to an increased risk of fragility fractures. In women, the disease mainly occurs due to the menopausal fall in estrogen levels, leading to an imbalance between bone resorption and bone formation and, consequently, to bone loss and bone fragility. Moreover, osteoporosis may affect men and may occur as a sequela to different diseases or even to their treatments. Despite their wide prevalence in the general population, the skeletal implications of many gastrointestinal diseases have been poorly investigated and their potential contribution to bone fragility is often underestimated in clinical practice. However, proper functioning of the gastrointestinal system appears essential for the skeleton, allowing correct absorption of calcium, vitamins, or other nutrients relevant to bone, preserving the gastrointestinal barrier function, and maintaining an optimal endocrine-metabolic balance, so that it is very likely that most chronic diseases of the gastrointestinal tract, and even gastrointestinal dysbiosis, may have profound implications for bone health. In this manuscript, we provide an updated and critical revision of the role of major gastrointestinal disorders in the pathogenesis of osteoporosis and fragility fractures.

Is there an association between peptic ulcer disease and osteoporosis: a systematic review and cumulative analysis

BACKGROUND

Mounting studies have emerged indicating that patients with peptic ulcer disease (PUD) are at a high risk of developing osteoporosis, but the evidence has not been previously synthesized. The present study aims to examine whether patients with PUD have a significantly higher prevalence of osteoporosis than the healthy normal subjects.

METHODS

Four electronic databases were systematically searched for eligible studies up to February 2020. The association between PUD and osteoporosis was evaluated by calculating the relative risk (RR) with a 95% confidence interval (CI).

RESULTS

Six observational studies were finally included, enrolling a total of 216 122 individuals. Synthetic results from the six included studies providing the number of cases for both sexes demonstrated that PUD was significantly associated with an increased risk of osteoporosis (95% CI, 1.37-1.89; P < 0.001). In line with this finding, the combined effect from the three studies independently reporting the male subjects also yielded to a positive relationship between PUD and osteoporosis (RR = 2.08; 95% CI,1.10-3.93; P = 0.023). However, when restricted to female participants, pooled results indicated that women patients with PUD would not suffer significantly more risk of osteoporosis than the general women population (RR = 1.36; 95% CI, 0.84-2.21, P = 0.212).

CONCLUSIONS

This is the first study for quantifying the positive association between PUD and the risk of osteoporosis by conducting a meta-analysis. In clinical practice, assessment of the bone mineral density and antiosteoporosis treatments are recommended for those potential patients with PUD.

Helicobacter pylori Related Diseases and Osteoporotic Fractures (Narrative Review)

Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.
