Most previous research investigating osteoporosis in rheumatoid arthritis (RA) has focused on female patients and there is a lack of data regarding clinical characteristics of osteoporosis in male patients with RA.The aim of this study was to compare the frequency of osteoporosis between male patients with RA and healthy patients, and to identify the risk factors for osteoporosis and low bone mineral density (BMD) in male patients with RA.We conducted a retrospective, cross-sectional study including 76 South Korean male patients with RA aged over 50 years and 76 age-matched male healthy individuals. BMD was measured at the lumbar spine (L1-4) and left hip (femoral neck and total hip) using dual energy X-ray absorptiometry. Osteoporosis was defined as a T-score of ≤ −2.5 according to the World Health Organization (WHO) classification.The frequency of osteoporosis at either the spine or the hip among male patients with RA was significantly higher than that among controls (22.4% vs 10.5%, P = .049) and RA patients had a significantly lower total hip BMD than healthy individuals (0.92 ± 0.14 vs 0.96 ± 0.1 g/cm2, P = .027). For male RA patients, the mean 28-joint Disease Activity Scores using erythrocyte sedimentation rate (DAS28-ESR) and body mass index (BMI) were 3.28 and 22 kg/m2, respectively. In multivariable logistic regression models, BMI ≤ 22 kg/m2 (odds ratio = 3.43, P = .043) and DAS28-ESR > 3.2 (odds ratio = 3.85, P = .032) were independent risk factors for osteoporosis at either site in male patients with RA.Our data demonstrate that male patients with RA had a 2.1 times higher risk for osteoporosis compared with healthy individuals. This suggests that appropriate management of osteoporosis in patients with RA is crucial not only for postmenopausal women but also for men aged over 50 years, especially those with low BMI and higher disease activity.

The objective of this study was to investigate the association of vitamin D deficiency with digital ulcers (DUs) that result from microvasculopathy, carotid intima-media thickness (CIMT) as surrogate markers of atherosclerosis, and brachial-ankle pulse wave velocity (baPWV) representing arterial stiffness in patients with systemic sclerosis (SSc). In this cross-sectional study, 40 female SSc patients and 80 healthy controls matched for sex, age, and blood sampling season were recruited. Vitamin D deficiency was defined as serum 25-OHD levels <30 ng/mL. "DUs ever" included active and healed DUs. CIMT and carotid plaque were examined using high-resolution ultrasonography, and baPWV was measured using an automatic waveform analyzer. Vitamin D deficiency was more prevalent in SSc patients than in controls (30 vs. 11.3%). Regarding SSc patients, 9 (22.5%) had DUs ever, and the mean CIMT and baPWV were 0.68 mm and 1561.1 cm/s, respectively; carotid plaque was detected in 13 (34.2%) patients. The frequency of DUs ever was significantly higher for SSc patients with vitamin D deficiency than those without this feature (50 vs. 10.7%, p = 0.012), but the median CIMT and baPWV and the frequency of carotid plaque did not differ according to the presence of vitamin D deficiency. Multivariable logistic regression analysis showed that vitamin D deficiency was an independent risk factor for DUs ever (OR = 7.72, p = 0.024). Vitamin D deficiency was associated with DUs, but not with atherosclerosis or arterial stiffness, potentially indicating that vitamin D may have different effects on the microvascular and macrovascular involvement in SSc pathophysiology.

Introduction:Amyloidosis accompanied by Sjögren's syndrome (SS) has been reported to occur primarily in the skin, lungs, tongue, and mammary gland. However, SS in association with secondary amyloidosis is rarely reported, and knowledge of its relevance is inadequate. Here we report a case of primary SS diagnosed simultaneously with localized amyloidosis of the lacrimal gland.Case presentation:A 45-year-old woman complaining of a left eyelid mass was referred to the hospital and was diagnosed with localized amyloidosis after excisional biopsy. She was then referred to the rheumatology department for additional evaluation for amyloidosis. Subsequently, her diagnosis was primary SS based on the presented symptoms and results of the Schirmer test, serologic testing, and minor salivary gland biopsy. Pilocarpine (10 mg/d) and hydroxychloroquine (200 mg/d) were initiated for the treatment of SS. Six months after the initial diagnosis, the dry eyes and mouth did not worsen and no masses suggestive of localized amyloidosis were reported.Conclusion:This is a rare case of amyloidosis, localized to the lacrimal gland, with SS. Therefore, despite its rarity, physicians should be aware of the potential coexistence of secondary amyloidosis, even in the localized form, in patients with SS.

Central serous chorioretinopathy may induce poor eyesight and serous retinal detachment. However, its exact cause has not been well established thus far. It can be associated with systemic high-dose corticosteroid treatment mainly for young and middle-aged men and may spontaneously regress or recur after withdrawal from corticosteroid. After corticosteroid administration for Behcet's disease, it is necessary to identify any ocular symptoms. Behcet's disease can lead to the development of ocular complications, such as uveitis, hypopyon, retinal vasculitis, optic neuritis, angiogenesis, secondary cataract, and glaucoma. It is possible to diagnose any of these complications via optical coherence tomography and digital indocyanine green angiography. It is easy to neglect an ocular symptom that may appear after a low-dose corticosteroid treatment as an ocular complication in patients with Behcet's disease. Thus, we report on a case concerning high-dose corticosteroid treatment with a literature review.

Raynaud syndrome is a medical condition that causes pain, numbness, and changes in skin color at the distal extremities. Raynaud syndrome can be subdivided into primary Raynaud's and secondary Raynaud's. The former is diagnosed when the cause is unknown and the latter is caused by an underlying condition, such as connective tissue diseases, injury, smoking, or certain medications. Both cancer chemotherapy and β-blockers are relatively common causes of Raynaud syndrome but there are no reports of its association with methimazole administration. The authors encountered a 43-year old woman with hyperthyroidism who developed digital ulcers associated with Raynaud syndrome after a methimazole treatment. Her digital ulcers and Raynaud syndrome were improved after methimazole was replaced with propylthiouracil and conventional therapy. This paper reports this case along with a review of the relevant literature. (J Rheum Dis 2018;25:203-206)
