The lower calcaneal QUS parameter stiffness in the Charcot foot in comparison with the control group, with the non-Charcot foot and with BMD in the lumbar spine and femoral neck, and its association with increased bone resorption indicate that calcaneal ultrasonometry may be useful in diagnosing the acute stage of CO and in assessing the risk of foot fracture.

Background/Aims: Small attention is paid to other types of bone diseases then chronic kidney disease-mineral and bone disorder in dialysis patients. The aim of our study was to assess the occurrence of osteoporosis and bone microarchitecture by trabecular bone score in this population. Methods: 59 patients (67.6 ± 13.1 years, 43 males) treated with hemodiafIltration underwent densitometry (Lunar Prodigy, TBS software 2.1.2) and laboratory assessment. Results: Osteoporosis was observed in 34% patients, high bone turnover was found in 80% of them, with SHPT (PTH > 300 ng/l) present in 69%. TBS was significantly decreased in 47.5% of the patients. TBS correlated with T- and Z-scores of the lumbar spine and proximal femur in the total population (P < 0.0001) and in men (P < 0.00001) and there were significant differences between TBS in groups with normal densitometry, osteopenia, and osteoporosis, both in total population (P < 0.0001; P < 0.01) and in men (P < 0.001; P < 0.001). Conclusions: Osteoporosis was found in about 1/3 of patients treated with hemodiafiltration. Normal TBS was found in only 1/4 of the dialysis population. TBS correlated with densitometric parameters and was significantly different relative to T-scores.

In a group of hemodialysis patients from one centre, T-score in proximal femur, low vitamin D, low BMI, and high FRAX for major osteoporotic fracture were associated with low-trauma fractures, however, in multi-variate analysis only low BMI remained a significant predictor of fracture risk.

Background: Acute anterior uveitis (AAU) is a relatively common extra-musculoskeletal manifestation of axial spondyloarthritis (axSpA); however, data on the prevalence of active sacroiliitis in patients with AAU are limited. Methods: 102 patients with AAU and 39 healthy subjects (HS) underwent clinical assessment and sacroiliac joint MRI. Patients with absence of active sacroiliitis were reassessed after two years. International Spondyloarthritis Society (ASAS) classification criteria for axSpA (regardless of patient’s age) and expert opinion for definitive diagnosis of axSpA were applied. Results: Although chronic back pain was equally present in both groups, bone marrow edema (BME) in SIJ and BME highly suggestive of axSpA was found in 52 (51%) and in 33 (32%) patients with AAU compared with 11 (28%) and none in HS, respectively. Out of all AAU patients, 41 (40%) patients fulfilled the ASAS classification criteria for axSpA, and 29 (28%) patients were considered highly suggestive of axSpA based on clinical features. Two out of the 55 sacroiliitis-negative patients developed active sacroiliitis at the two-year follow-up. Conclusions: One-third of patients with AAU had active inflammation on SIJ MRI and clinical diagnosis of axSpA. Therefore, patients with AAU, especially those with chronic back pain, should be referred to a rheumatologist, and the examination should be repeated if a new feature of SpA appears.
