Sarcopenia and anemia are common complications in patients with Crohn's Disease (CD). However, few studies have shown the association between sarcopenia and hemoglobin levels in CD patients. This retrospective study aimed to explore such association in Chinese patients with CD. Two hundred and twelve adult CD inpatients who underwent computed tomography (CT) or magnetic resonance imaging (MRI) examinations from July 2019 to December 2021 were included in the study. Sarcopenia was defined according to the cutoff value of skeletal muscle index of lumbar spine 3 (SMI-L3) (< 44.77cm2/m2 for males and < 32.5cm2/m2 for females). The CD patients were divided into two groups based on the presence or absence of sarcopenia. Clinical data, hemoglobin levels, and other laboratory data were retrospectively collected. The association between hemoglobin levels and sarcopenia was analyzed by univariable and multivariable logistic regression analysis. Sarcopenia occurred in 114 CD patients (53.8%). Compared to patients without sarcopenia, patients with sarcopenia had a lower proportion of L1 (30.7% vs. 45.8%, p = 0.032) and B1 classification (58.8% vs. 72.4%, p = 0.037). Patients with sarcopenia had significantly lower levels of hemoglobin (Hb) (116.5 ± 22.8 vs. 128.1 ± 21.0, p < 0.001). The prevalence of sarcopenia increased with the decrease in hemoglobin level (p for trend < 0.05). Linear regression analysis showed that hemoglobin levels were associated with SMI-L3 (β = 0.091, p = 0.001). Multivariable logistic regression analysis found that higher hemoglobin levels (OR:0.944; 95% CI: 0.947,0.998; p = 0.036) were independent protective factors for sarcopenia. Lower hemoglobin levels are independently associated factors of sarcopenia in adult Chinese patients with CD. [ABSTRACT FROM AUTHOR]

Others A recent study reported that the risk of malignancy in SAPHO patients was higher than that in patients with psoriatic arthritis (hazard ratio 6.70; 95% confidence interval 2.227-20.13).[30] The etiology is not completely understood, but the chronic inflammation caused by SAPHO syndrome may play a critical role.[30] CONCLUSION AND PERSPECTIVE In conclusion, a wide range of manifestations are associated with SAPHO syndrome besides synovitis, acne, pustulosis, hyperostosis, and osteitis. Moreover, other pulmonary manifestations, such as patchy shadows (32.8%), ground-glass opacity (16.4%), and pleural thickening (13.4%), were not uncommon in SAPHO patients.[29] The etiology of brain and pulmonary manifestation within SAPHO syndrome is not understood. SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome is a rare clinical entity. A recent case-control study compared the bone mass and prevalence of osteoporosis between healthy persons and SAPHO patients.[14] Twenty-seven SAPHO patients and 70 healthy persons were included.

Background Sarcopenia and bone loss are both common in older individuals. However, the association between sarcopenia and bone fractures has not been evaluated longitudinally. In this study, we evaluated the association between computed tomography (CT)-based erector spinae muscle area and attenuation and vertebral compression fracture (VCF) in elderly individuals in a longitudinal study. Methods This study recruited individuals 50 years of age and older, who did not have VCF and underwent CT imaging for lung cancer screening during January 2016 to December 2019. Participants were followed up annually until January 2021. Muscle CT value and muscle area of the erector spinae were determined for muscle assessment. Genant score was used to define new-onset VCF. Cox proportional hazards models were used to assess the association between muscle area/attenuation and VCF. Results Of the 7 906 included participants, 72 developed new VCF over a median follow-up of 2 years. Large area of the erector spinae (adjusted hazard ratio [HR] = 0.2, 95% confidence interval [CI]: 0.1–0.7) and high bone attenuation (adjusted HR = 0.2, 95% CI: 0.1–0.5) were independently associated with VCF. High muscle attenuation was associated with severe VCF (adjusted HR = 0.46, 95% CI: 0.24–0.86). The addition of muscle area improved the area under the curve of bone attenuation from 0.79 (95% CI: 0.74–0.86) to 0.86 (95% CI: 0.82–0.91; p  = .001). Conclusions CT-based muscle area/attenuation of the erector spinae was associated with VCF in elderly individuals, independently of bone attenuation. The addition of muscle area improved the performance of bone attenuation in predicting VCF. [ABSTRACT FROM AUTHOR]
