No Increased Risk for Primary Osteoarthritis in Liver Cirrhosis - A Danish Nationwide Cohort Study

Genetic evidence of the causal relationship between chronic liver diseases and musculoskeletal disorders

BACKGROUND

Chronic liver diseases constitute a major global public health burden, posing a substantial threat to patients' daily lives and even survival due to the potential development of musculoskeletal disorders. Although the relationship between chronic liver diseases and musculoskeletal disorders has received extensive attention, their causal relationship has not been comprehensively and systematically investigated.

METHODS

This study aimed to assess the causal relationships between viral hepatitis, primary biliary cholangitis, primary sclerosing cholangitis (PSC), liver cirrhosis, and hepatocellular carcinoma (HCC) with osteoporosis, osteoarthritis, and sarcopenia through bidirectional Mendelian randomization (MR) research. The traits related to osteoporosis and osteoarthritis included both overall and site-specific phenotypes, and the traits linked to sarcopenia involved indicators of muscle mass and function. Random-effect inverse-variance weighted (IVW), weighted median, MR-Egger, and Causal Analysis Using the Summary Effect Estimates were used to evaluate causal effects, with IVW being the main analysis method. To enhance robustness, sensitivity analyses were performed using Cochran's Q test, MR-Egger intercept, MR-PRESSO global test, funnel plots, leave-one-out analyses, and latent causal variable model.

RESULTS

The forward MR analysis indicated that PSC can reduce forearm bone mineral density (beta = - 0.0454, 95% CI - 0.0798 to - 0.0110; P = 0.0098) and increase the risk of overall osteoarthritis (OR = 1.012, 95% CI 1.002-1.022; P = 0.0247), while HCC can decrease grip strength (beta = - 0.0053, 95% CI - 0.008 to - 0.0025; P = 0.0002). The reverse MR analysis did not find significant causal effects of musculoskeletal disorders on chronic liver diseases. Additionally, no heterogeneity or pleiotropy was detected.

CONCLUSIONS

These findings corroborate the causal effects of PSC on osteoporosis and osteoarthritis, as well as the causal impact of HCC on sarcopenia. Thus, the implementation of comprehensive preventive measures is imperative for PSC and HCC patients to mitigate the risk of musculoskeletal disorders, ultimately improving their quality of life.

Assessing the Awareness Regarding Osteoarthritis and Its Related Risk Factors Among Women in Aseer Central Hospital

Background Osteoarthritis (OA) is the most common form of arthritis worldwide and is characterized by the gradual loss of joint cartilage, leading to stiffness, discomfort, and restricted movement. This research aims to assess the knowledge of obese women in the Aseer region regarding OA and its associated risk factors. OA predominantly affects the knees, hands, and hips, with knee OA being particularly significant due to its high incidence rate and early onset in obese women. In Saudi Arabia, there are varying levels of awareness among the population, but no study has focused on obese females. This study seeks to address this gap and enhance the understanding of OA in this demographic. Methodology A cross-sectional research design was employed using a self-administrated questionnaire collected by a group of trained data collectors who distributed the questionnaires throughout the clinics of Aseer central hospital. The questionnaire was divided into two sections. The first section collected demographic data about the participants, and the second section was a 20-item questionnaire about OA and its related risk factors. The study was conducted in the Aseer region. A total of 278 subjects (female) were included in the study. Statistical analysis was performed using SPSS version 27.0.1.0 (IBM Corp., Armonk, NY, USA). Results This study analyzed the sociodemographic characteristics of 278 participants. All participants were female, were young to middle-aged adults, and had a collegiate education. On average, participants were overweight, with varying knowledge levels about OA. While some correctly identified symptoms and risk factors. Many participants responded with "I Don't Know" regarding joint stiffness as a symptom (37.7%). Comparing knowledge among different body mass index groups revealed no significant differences, except for misconceptions about the cause of OA among overweight individuals (39.06%). Conclusions This study's findings underscore the practical implications for patient education and healthcare strategies. The varying levels of awareness among obese women in the Aseer region regarding OA emphasize the need for increased education and targeted health promotion interventions. Addressing misconceptions and improving knowledge can enhance treatment plans and contribute to better patient outcomes. Understanding these knowledge gaps is crucial for improving patient education, healthcare strategies, and OA management.

Knowledge of knee osteoarthritis among general population in Aseer region

Background

Osteoarthritis (OA) is the most common articular disease of the developed country and cause of chronic disability, and may cause joint failure. OA is one of the most prevalent situation that gives rise to disability, especially in elderly population.

Aim

To assess the knowledge of knee OA among general population in Aseer region.

Materials and Methods

A cross-sectional survey was conducted in Aseer region including 1052 participants. The participants were included by visiting the public areas in different cities in Aseer region where many people of different social and economic level were available, and because of the the nature of Saudi community regarding home-to-home interviews.

Results

The research included 1052 participants from different areas in Aseer region. The ages of participants ranged from 17 to 80 years old, with a mean age of 38 ± 12 years old. Approximately 89.0% of the sampled population had good awareness regarding preventive measures of knee OA. The second highest awareness level was recorded for relieving the measures of knee OA as 84.1% of the sampled population recorded good level of knowledge. In general, 82.6% of the population had good awareness level regarding OA in total.

Conclusions and Recommendations

The current research revealed that the awareness of the general population in Aseer region regarding knee OA was more than satisfactory, especially for preventive measures, relieving measures, and its risk factors.
