1.Management of the arthritis related osteoporosis.
Korean Journal of Medicine 2006;70(1):119-125
The osteoporosis is frequently observed in the patients with the inflammatory arthritis and painful rheumatism. The treatment of the osteoporosis for them is different from that for the patients without the arthritis or rheumatism. The recently developed biologic agents blocking tumor necrosis factor, interleukin(IL)-1, IL-6, or receptor activator of nuclear factor-kappaB ligand (RANKL) which are designed to treat the inflammatory arthritis are also expected to heal the osteoporosis in the inflammatory arthritis. The early use of the bisphosphonate is useful to prevent the glucocorticoid induced bone loss and to treat the spondyloarthropathy including the SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome. The clacitonin is useful for the painful rheumatism and osteoporotic fracture. The estrogen replacement is disputed because the stroke is known to occur more commonly in chronic inflammatory rheumatism than in general population. Moreover the pathogenesis of the most rheumatism may be partly related to the hormone. The parathyroid hormone therapy needs caution in the patients with calcium deposition disease and the hyperuricemia. We are reviewing the recent trend and development in the management of the primary, secondary and inflammatory osteoporosis in the patients with arthritis.

2.Animal Models of Spondyloarthritis.
Journal of Rheumatic Diseases 2012;19(5):248-253
The clinical spectrum of spondyloarthritis is included various diagnostic entities that share clinical, genetic and pathological characteristics. As human tissue specimens of the sacroiliac joints are very difficult to obtain, most of the new concepts have emerged from different animal models of disease. Animal models are available for the study of several different aspects of spondyloarthritis. The models include human leukocyte antigen (HLA) B-27 based on transgenic rat and mouse models, inflammation-driven models, and models of ankylosing enthesitis. Areas of investigation to which these models contribute include the role of HLA B-27, process of spinal and peripheral joint inflammation and calcification, immune responses to candidate antigens and the role of tumor necrosis factor.

Kawasaki disease or mucocutaneous lymph node syndrome is an acute inflammatory illness of childhood characterized by systemic panvasculitis. It presents with high fever, dramatic changes of the skin and mucous membranes, and lymphadenopathy. Adult-onset Kawasaki disease is rare and reports on coronary involvement in adult are even rarer. Herein, we report a case of adult-onset Kawasaki disease complicated by splenic infarction and development of coronary aneurysm even despite of treatment with intravenous gamma globulin. A 20-year-old man presented with fever, erytheatous rash, induration and desquamation of hands and feet, pulmonary edema and shock due to cardiomyopathy, splenic infarction, bilateral conjunctivitis, jaundice, and cervical lymphadenopathy. After Kawasaki disease was suspected, intravenous gamma globulin (2 g/kg once) and aspirin (6 g/day) were administered. On the 30th hospital day, transesophageal echocardiography showed one coronary aneurysm and coronary angiography showed three aneurysms. Eight months after the first admission, follow-up coronary angiography showed normalization of the previous coronary abnormalities.

The object of this study was to evaluate the effect of uric acid lowering therapy in reducing the new development of comorbidities and the frequency of acute attacks in gout patients. We retrospectively reviewed patients who were diagnosed to have gout with at least 3 yr of follow up. They were divided into 2 groups; 53 patients with mean serum uric acid level (sUA)<6 mg/dL and 147 patients with mean sUA> or =6 mg/dL. Comorbidities of gout such as hypertension (HTN), type II diabetes mellitus (DM), chronic kidney disease, cardiovascular disease (CVD) and urolithiasis were compared in each group at baseline and at last follow-up visit. Frequency of acute gout attacks were also compared between the groups. During the mean follow up period of 7.6 yr, the yearly rate of acute attack and the new development of HTN, DM, CVD and urolithiasis was lower in the adequately treated group compared to the inadequately treated group. Tight control of uric acid decreases the incidence of acute gout attacks and comorbidities of gout such as HTN, DM, CVD and urolithiasis.

A 41-year-old woman was admitted because of dyspnea on exertion for one month. She was diagnosed to have systemic lupus erythematosus 4 years ago and has taken prednisolone and azathioprine. One month prior to admission she visited dental clinic for painful gingival swelling and gingival biopsy was performed. Physical examination showed multiple round elevated purpuric rashes in thoracic wall. Gingiva and skin biopsy showed Kaposi's sarcoma. Computed tomography of abdomen and chest revealed ill-defined nodules in both lung fields and multiple small para-aortic lymphadenopathies. Chemotherapy with paclitaxel was given for Kaposi's sarcoma. Prednisolone was tapered. After the 7th course of chemotherapy, the lesions show marked improvement in size and number.

PURPOSE: The aim of the study was to investigate the change in usage and clinical outcomes of using a humidified high flow nasal cannula (HHFNC) in preterm infants. METHODS: A retrospective review of patients with gestational age <32 weeks born at our neonatal intensive care unit from January 2008 to March 2011 was performed. First, data were compared between Era 1 (January 2008 to February 2009) and Era 2 (March 2009 to March 2011) to describe the increased usage of HHFNC. Second, the patients (gestational age 25-30 weeks) were divided into two groups to compare clinical outcomes. nasal continuous positive airway pressure (NCPAP) and HHFNC groups who received either NCPAP or HHFNC as a respiratory support within 14 days of birth. RESULTS: Compared to Era 1, HHFNC usage increased from 10 to 55% in Era 2, whereas NCPAP usage decreased from 40 to 5%. No difference in pulmonary or adverse outcomes including the incidence of reintubation and bronchopulmonary dysplasia (BPD), days on oxygen and a ventilator, and other outcomes was observed between the HHFNC and NCPAP groups. Days to reach full feed (32.2+/-16.7 vs. 24.7+/-10.2, P=0.05) and regain birth weight (20.9+/-16.9 vs. 17.2+/-4.3, P=0.04) decreased in the HHFNC group. CONCLUSION: HHFNC was feasible and did not differ in respiratory and other outcomes, but days to reach full feed and regain birth weight decreased in the HHFNC, when compared with the NCPAP. An additional prospective multicenter designed study is needed to better define safety and efficacy of HHFNC.

OBJECTIVE: To compare the safety and efficacy associated with the addition of etanercept (ETN) with that of leflunomide (LEF) in Korean rheumatoid arthritis (RA) patients, who inadequately respond to methotrexate (MTX) in a randomized, open-label study. METHODS: Twenty-nine subjects suffering moderate to severe RA, despite MTX treatment were randomly assigned to a combination therapy with either ETN or LEF. The primary end-point was the proportion of subjects achieving American College of Rheumatology (ACR20) criteria at week 16. RESULTS: Ninety percent (n=18) of the ETN+MTX group (n=20) and 22.2% (n=2) of the LEF+MTX group (n=9) achieved an ACR20 response (p=0.001). All patients (n=20) in the ETN+MTX group showed moderate or good EULAR response as compared with 55.6% (n=5) in the LEF+MTX group (p=0.012). All of the ETN+MTX subjects completed the study without adverse events. Adverse events occurred in 77.8% (n=7) of cases in the LEF+MTX group; significantly elevated serum AST/ALT levels in 6 subjects and mild neutropenia (ANC < 1,500/microL) in 1 subject. CONCLUSION: The ETN+MTX combination therapy was effective and safe, whereas the LEF+MTX combination therapy resulted in moderate efficacy in only half of the cases, and was accompanied by a high rate of adverse events. Elevated AST/ALT was the most common adverse event causing dose adjustment or discontinuation of therapeutic agent in the LEF+MTX group.

We investigated acute effects of intermittent large dose bisphophonate therapy in osteoporotic patients. Peripheral blood mononuclear cells were incubated with alendronate (100 micrometer) for 18 hr, in vitro and cytokine expressions were measured by real-time RT-PCR. Pamidronate 30 mg was administered on 26 osteoporotic patients; and acute phase reactants, inflammatory cytokines and bone biomarkers were measured. The in vitro study showed significant increase in mRNA expression of IL-6, TNF-alpha and IFN-gamma. A notable rise in serum C-reactive protein (CRP) was observed over 3 days after pamidronate infusion (P=0.026). Serum levels of TNF-alpha, IL-6 and IFN-gamma were also significantly increased (P=0.009, 0.014, 0.035, respectively) and the increase in IL-6 levels were strongly correlated with CRP levels (P=0.04). Serum calcium and c-telopeptide levels rapidly decreased after the treatment (P=0.02, <0.001, respectively). This study showed that mRNA expression of inflammatory cytokines at peripheral blood mononuclear cells (PBMC) level were observed within 18 hr and marked elevation of inflammatory cytokines and acute phase reactants were demonstrated after pamidronate infusion at the dose for osteoporosis. Our studies confirmed that intermittent large dose aminobisphosphonate causes acute inflammation.
