Raynaud's phenomenon (RP) is frequent in autoimmune connective tissue diseases (AICTD) and its approach includes nailfold capillaroscopy (NFC), as it is a non-invasive technique that permits direct visualization of the microcirculation. The aim of this study is to analyze and establish clinical correlations between NFC findings and particular aspects of autoimmune disorders. This is a retrospective study. ⋯ In MCTD, scleroderma pattern relates to myositis. SLE and APS reveal significant hemorrhages, but not related to APS antibodies. This study highlights the possible role of NFC as biomarker of AICTD, particularly in SSc and IIM.

Review Case Reports
Adult-onset Still's disease with macrophage activation syndrome diagnosed and treated based on cytokine profiling: a case-based review.
Adult-onset Still's disease (AOSD) is a relatively rare systemic inflammatory disorder and is diagnosed using various sets of classification criteria, with the Yamaguchi criteria as the most widely used criteria. Herein, we present the case of a 21-year-old woman admitted with a high fever, lasting for over 1 month, who did not fulfill the Yamaguchi criteria. ⋯ In addition, we predicted the occurrence of macrophage activation syndrome by a characteristic increase in the soluble tumor necrosis factor receptor II level, which allowed a timely intervention for this malicious complication. Therefore, we suggest that cytokine profiling will be useful for the diagnosis and management of AOSD.

Review Case Reports
Isotretinoin-induced sacroiliitis in patients with hidradenitis suppurativa: a case-based review.
Hidradenitis suppurativa (HS) is a chronic, suppurative skin disease characterized by painful nodules, particularly in the axillae and groin. Isotretinoin can be used in the treatment of HS; however, it may paradoxically lead to skin lesions or worsen the existing lesions. Isotretinoin, which is commonly used in the treatment of severe acne, is associated with several side effects, including rheumatic side effects and rarely sacroiliitis. ⋯ After the treatment, both low back pain and HS lesions regressed. Patients with isotretinoin therapy should be alerted for inflammatory low back pain and HS lesions that may develop. We should note that biologic agents should be considered in the treatment of resistant cases.

Anti-neutrophil cytoplasmic antibody (ANCA) may target proteinase 3 (PR3) or myeloperoxidase (MPO). Although a few patients with vasculitis have both MPO- and PR3-ANCA, the details of their clinical characteristics are not known. The objective of this study was to analyze the characteristics of patients with dual MPO- and PR3-ANCA-positive vasculitis. ⋯ Age at diagnosis, kidney involvement, and upper airway involvement were associated with ANCA type. Patients with dual-ANCA-positive vasculitis had considerably more kidney dysfunction than patients with MPO- PR3+ AAV. They also had more upper airway involvement than patients with MPO+ PR3- AAV.

Observational Study
LAUDES Study: impact of digital ulcers on hand functional limitation, work productivity and daily activities, in systemic sclerosis patients.
The objective of this study was to evaluate the impact of digital ulcers (DUs) in daily life of systemic sclerosis (SSc) Spanish patients. We developed a multicenter observational study to compare functional disability in SSc patients with active DUs vs. those without DUs. An additional correlation between perception of patients and physicians on disability due to DUs was performed. ⋯ Impact on daily activities was significantly higher in patients with DUs (p = 0.002), with a non-significant trend to experience higher impact on work productivity (p = 0.07). A high correlation was found between DUs patients and physicians opinion on the impact of DUs (daily life: Pearson R = 0.86; work productivity: Pearson R = 0.87). Study findings show an impaired hand function and increased disability for daily life activities and work productivity in SSc patients with DUs compared with patients without DUs in Spanish population.
