A primary adenosquamous carcinoma of the liver is a rare subtype of a cholangiocarcinoma. Adenosquamous carcinoma is known to have an aggressive biologic behavior and is associated with a poor prognosis. Recently, we experienced a case of a primary adenosquamous carcinoma of the liver. A 69-year-old man was subjected to a right hemicolectomy five months ago due to an ascending colon cancer. At a periodic check-up, abdominal ultrasonography and magnetic resonance imaging showed a ~1.1 cm-sized hepatic mass which was highly suspicious of being a hepatic metastasis from the ascending colon cancer. A hepatic segmentectomy was performed. The tumor was microscopically composed of an adenocarcinoma and a squamous cell carcinoma, and it was different from the previous colon cancer as determined by immunohistochemistry. Three months after the hepatic segmentectomy, multiple hepatic metastasis was found and the patient has been treated as an outpatient with capecitabine.

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.

BACKGROUND/AIMS: Our aim was to assess whether short-term treatment with soluble tumor necrosis factor (TNF) receptor affects circulating markers of bone metabolism in rheumatoid arthritis (RA) patients. METHODS: Thirty-three active RA patients, treated with oral disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids for > 6 months, were administered etanercept for 12 weeks. Serum levels of bone metabolism markers were compared among patients treated with DMARDs at baseline and after etanercept treatment, normal controls and naive RA patients not previously treated with DMARDs (both age- and gender-matched). RESULTS: Bone-specific alkaline phosphatase (BSALP) and serum c-telopeptide (CTX)-1 levels were lower in RA patients treated with DMARDs than in DMARD-naive RA patients. After 12 weeks of etanercept treatment, serum CTX-1 and sclerostin levels increased. In patients whose DAS28 improved, the sclerostin level increased from 1.67 +/- 2.12 pg/mL at baseline to 2.51 +/- 3.03 pg/mL, which was statistically significant (p = 0.021). Increases in sclerostin levels after etanercept treatment were positively correlated with those of serum CTX-1 (r = 0.775), as were those of BSALP (r = 0.755). CONCLUSIONS: RA patients treated with DMARDs showed depressed bone metabolism compared to naive RA patients. Increases in serum CTX-1 and sclerostin levels after short-term etanercept treatment suggest reconstitution of bone metabolism homeostasis.

OBJECTIVE: This study examines the effects of tumor necrosis factor (TNF) blockade on markers of bone metabolism in peripheral blood from active rheumatoid arthritis (RA) patients. METHODS: Eighteen patients (16 women, 2 men) aged 50 years (range 37-63 years), with persistently active RA (mean disease duration 7 years) were studied. Most took methotrexate (mean dose 12.5 mg) and all except one received corticosteroid (mean dose 5.7 mg). Four were treated with etanercept, eight received adalimumab and six received infliximab. Before and six months after taking TNF blockers, blood was sampled to obtain peripheral blood mononuclear cells (PBMCs), and serum bone turnover markers and acute phase reactants were measured. PBMCs were seeded and cultured to produce osteoblastic lineage cells and osteoclasts. RESULTS: The formation of calcified nodules by osteoblastic lineage cells from PBMC increased from 205.7±196.3 µmol/well at the baseline to 752.5±671.9 µmol/well after TNF blockade (p<0.024). The serum levels of bone formation markers, including bone specific alkaline phosphatase and osteocalcin also increased. The number of circulating osteoclasts and area of bone resorption pits made by osteoclasts were reduced after TNF blockade. CONCLUSION: The activity of circulating osteoblastic lineage cells increased after TNF blockade, whereas peripheral osteoclastogenesis tended to be suppressed. This is the first study of cultured human peripheral osteoblastic lineage cells in RA patients. Given that peripheral bone formation is difficult to study using radiologic methods, culture of these cells may provide a new modality for studying bone metabolism in RA.

BACKGROUND/AIMS: This study sought to evaluate the diagnostic value of salivary gland ultrasonography in primary Sjogren's syndrome with anti-Ro/SS-A antibody. The secondary goal was to assess the relationship between the grade of parenchymal inhomogeneity and the anti-Ro/SS-A antibody titer or clinical manifestations. METHODS: The parotid and submandibular glands were examined ultrasonographically in 30 patients having primary Sjogren's syndrome with anti-Ro/SS-A antibody and 30 control subjects with no evidence of Sjogren's syndrome. The ultrasonographic definition of parenchymal inhomogeneity of the salivary glands was blurred glandular borders, multiple hyperechoic bands, and hypoechoic areas. The parenchymal inhomogeneity of the glands was categorized into four grades. RESULTS: Parenchymal inhomogeneity of the parotid gland was seen in 25 (83.3%) patients with primary Sjogren's syndrome and 2 (6.7%) control subjects. Of these cases, the submandibular gland showed parenchymal inhomogeneity in 24 (80%) patients with primary Sjogren's syndrome and 2 (6.7%) control subjects. The sensitivity and specificity of parenchymal inhomogeneity of the parotid gland were 83.3% and 93.3%, respectively, and 80% and 93.3% for the submandibular gland. The grade of ultrasonographic parenchymal inhomogeneity was related to a diagnosis of Sjogren's syndrome (p<0.001) and the time of dissolution of the wafer, but had no relationship with the anti-Ro/SS-A antibody titer. A high degree of interobserver agreement was found in the assessment of parenchymal abnormalities of the salivary gland (parotid gland: kappa=0.859; submandibular gland: kappa=0.837). CONCLUSIONS: Salivary gland ultrasonography is a useful method for visualizing glandular structural changes and making a diagnosis of primary Sjogren's syndrome.

Early differentiation between bacterial infections and disease flares in autoimmune disease patients is important due to different treatments. Seventy-nine autoimmune disease patients with symptoms suggestive of infections or disease flares were collected by retrospective chart review. The patients were later classified into two groups, disease flare and infection. C-reactive protein (CRP) and serum procalcitonin (PCT) levels were measured. The CRP and PCT levels were higher in the infection group than the disease flare group (CRP,11.96 mg/dL +/- 9.60 vs 6.42 mg/dL +/- 7.01, P = 0.003; PCT, 2.44 ng/mL +/- 6.55 vs 0.09 ng/mL +/- 0.09, P < 0.001). The area under the ROC curve (AUC; 95% confidence interval) for CRP and PCT was 0.70 (0.58-0.82) and 0.84 (0.75-0.93), which showed a significant difference (P < 0.05). The predicted AUC for the CRP and PCT levels combined was 0.83, which was not significantly different compared to the PCT level alone (P = 0.80). The best cut-off value for CRP was 7.18 mg/dL, with a sensitivity of 71.9% and a specificity of 68.1%. The best cut-off value for PCT was 0.09 ng/mL, with a sensitivity of 81.3% and a specificity of 78.7%. The PCT level had better sensitivity and specificity compared to the CRP level in distinguishing between bacterial infections and disease flares in autoimmune disease patients. The CRP level has no additive value when combined with the PCT level when differentiating bacterial infections from disease flares.
