A 66-year-old woman with rheumatoid arthritis presented with unilateral leg edema attributable to an enlarged iliopsoas bursa with presumed impedance of lymphatic drainage. The adjacent hip joint was not severely involved by arthritis. Ultrasonography and computed tomography were used to delineate the bursal mass and demonstrate communication with the joint space.

We report an autopsy case of elderly-onset anticentromere antibody-positive pulmonary-renal syndrome. An 84-year-old woman was admitted to our hospital with complaints of leg edema and general malaise. Neither skin rush nor arthritis was seen. Because of hematuria, proteinuria with various casts, renal dysfunction and anemia, a clinically diagnosis of rapidly progressive glomerulonephritis was made. Slight pulmonary hypertension was observed in ultrasonic cardiography. Hypocomplementemia was not seen. Tests for MPO- and PR 3-anti-neutrophil cytoplasmic antibodies and anti-glomerular basement membrane antibody were negative, but a high titer of antinuclear antibody with a discrete speckled pattern on immunofluorescent staining was disclosed. Results for anticentromere antibody and anti-Ki antibody were positive, but for anti-Sm antibody and anti-double stranded DNA antibody were both negative. She did not present any clinical features of systemic sclerosis or CREST syndrome. Subsequently, prednisolone was administered, but pulmonary alveolar hemorrhage occurred and the patient died of acute respiratory failure caused by massive pulmonary hemorrhage. Autopsy revealed crescentic glomerulonephritis including glomerular capillaritis and pulmonary capillaritis with positive granular deposits of immunoglobulins and compliment on the glomerular and pulmonary capillary walls. Immunologically mediated crescentic glomerulonephritis and pulmonary capillaritis was then diagnosed histopathologically. The main pathological feature of the case was small-vessel vasculitis with immune-complex deposition. Although this case did not fulfill the clinical criteria for systemic lupus erythematosus (SLE), its histological features resembled those of lupus nephritis and acute lupus pneumonitis. We speculated that anticentromere antibody-positive pulmonary-renal syndrome without any other symptoms or signs of connective tissue disease, such as our case, is a clinical entity distinct from typical SLE or CREST syndrome.

Cutaneous arteritis (cutaneous polyarteritis nodosa, CA) is a necrotizing vasculitis of arteries within the skin. CA is a new classification under single-organ vasculitis, as adopted by the 2012 Chapel Hill consensus conference (CHCC 2012). Some patients originally diagnosed as having CA could develop additional disease manifestations that warrant reclassifying as systemic polyarteritis nodosa (PAN) according to the CHCC 2012. We retrospectively investigated 101 patients with CA seen at our department between 2003 and 2012. There was a significantly higher frequency of inflammatory plaques and leg edema in CA patients with elevated C-reactive protein (CRP) compared to CA patients with normal CRP. Similarly, there were significant differences in the incidence of arthralgia and mononeuritis multiplex between the two patient groups. We found significantly positive correlations between CRP and creatinine titers in serum in all 101 CA patients. Prednisolone was administrated in a significantly greater percentage of patients with elevated CRP compared to patients with normal CRP. Repeated i.v. cyclophosphamide pulse therapy (IV-CY) with prednisolone therapy at an early stage resulted in complete resolution without adverse effects or severe complications. We regard inflammatory plaques and leg edema with elevated serum CRP as an indication of a more severe condition, and treated them effectively with prednisolone. Assuming mononeuritis multiplex and/or arthritis exist with elevated CRP, we propose that earlier treatment by IV-CY with prednisolone should be indicated for CA patients who demonstrate these more severe manifestations to prevent progression to PAN.

Blau syndrome is a rare disorder that is classically characterised by granulomatous arthritis, skin eruptions and uveitis, which occur in the absence of lung involvement. Blau syndrome has been linked to encoding mutations in the NOD-2 gene and is inherited in an autosomal dominant form. The most commonly observed mutations are missense substitutions affecting the arginine residue at position 334. The rare E600A mutation has been described as causing uveitis without skin involvement. Our patient is a 54-year-old man with an unusual heterozygous c.1799A>C(E600A) mutation, who was seen for bilateral lower extremity swelling and pain. On physical examination, he was found to have lower leg oedema with decreased hair growth on the affected area. Biopsy showed non-caseating micro-granulomas consistent with a diagnosis of Blau syndrome. The patient had excellent response to colchicine, but this was stopped because he developed elevated transaminases. Thus, we present an unusual genetic form of a rare condition and we demonstrate skin involvement in a subtype where cutaneous involvement has not hitherto been reported. In addition, the type and presentation of the skin involvement is different from that normally found in classic Blau syndrome. Finally, we report his response to colchicine, although it was ultimately not tolerated by this patient.

The symptomatology of lupus nephritis (LN) consists of foamy urine and lower leg edema, as well as such systemic manifestations as oral ulcers, arthralgia/arthritis, and lymphadenopathy. However, these symptoms may appear mild and non-specific. If these symptoms are unrecognized, thus delaying treatment, approximately 10% of LN patients will develop permanent kidney damage and end-stage kidney disease. Therefore, the purpose of this study is to identify a surrogate biomarker for the early detection of LN. In this study, we first adopted next generation sequencing (NGS) in order to screen differential expression levels of microRNA between SLE patients with and without LN. The results of both the NGS and the literature review confirmed the potential of 15 microRNAs through real-time qPCR. We further considered clinical laboratory data for additional analysis. In total, 41 microRNAs demonstrated significant differences through NGS screening. We then verified eight microRNAs from NGS and seven microRNAs from the literature review using the real-time qPCR method in peripheral mononuclear cells. Ultimately, mir-125a-5p, miR-146a-5p, and mir-221-3p were found to be statistically significant not only in the screening study but also in the real-time qPCR verification studies. miR-146a-5p was observed to have a significant correlation with clinical biochemistry markers, as well as to be a surrogate biomarker for the early detection of lupus nephritis. This study is the first to show that the intracellular biomarker miR-146a-5p may serve as a useful specific biomarker for the detection of lupus nephritis among lupus patients in the future, regardless of serum albumin levels and spot urine protein/creatinine ratio.
