Correlation between low bone density and disease activity in patients with ulcerative colitis.

Area of Science:

• Gastroenterology
• Endocrinology
• Radiology

Background:

• Inflammatory bowel diseases, including ulcerative colitis, are associated with an increased prevalence of low bone mineral density.
• Dual-energy X-ray absorptiometry (DXA) is a key diagnostic tool for assessing bone health.

Purpose of the Study:

• To investigate the correlation between bone mineral density and disease activity in patients diagnosed with ulcerative colitis.
• To evaluate bone density at the spine, femur neck, and hip in this patient cohort.

Main Methods:

• A cross-sectional study involving 52 ulcerative colitis patients with disease duration under 5 years.
• Data collection included demographic information, Simple Clinical Colitis Activity Index, serum calcium, phosphorus, vitamin D levels, and DXA scans.
• Statistical analysis employed SPSS software, including Kolmogorov-Smirnov, T-tests, ANOVA, Mann-Whitney U, Kruskal-Wallis, and Chi-square tests.

Main Results:

• The mean age of patients was 37.72 years, with a mean disease activity score of 4.78.
• Low bone density was observed in 30.8% (spine), 11.5% (femur neck), and 15.4% (hip).
• No statistically significant correlation was found between bone density (Z-score) at the total hip, spine, or femur neck and disease activity, age, or disease duration (p>0.05).

Conclusions:

• A notable proportion of ulcerative colitis patients exhibit low bone density.
• Disease activity, age, and disease duration do not appear to be directly correlated with bone density in this patient group.
• Further research is warranted to explore other contributing factors to low bone density in ulcerative colitis.
