Abstract
Introduction The proportion of older patients diagnosed with advanced-stage non-small cell lung cancer (NSCLC) has been increasing. Immune checkpoint inhibitor (ICI) monotherapy (MONO) and combination therapy of ICI and chemotherapy (COMBO) are standard treatments for patients with NSCLC and programmed cell death ligand-1 (PD-L1) tumor proportion scores (TPS) ≥ 50%. However, evidence from the clinical trials specifically for older patients is limited. Thus, it is unclear which older patients benefit more from COMBO than MONO. Methods We retrospectively analyzed 199 older NSCLC patients of Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1 and PD-L1 TPS ≥ 50% who were treated with MONO or COMBO. We analyzed the association between treatment outcomes and baseline patient characteristics in each group, using propensity score matching. Results Of the 199 patients, 131 received MONO, and 68 received COMBO. The median overall survival (OS; MONO: 25.2 vs. COMBO: 42.2 months, P = 0.116) and median progression-free survival (PFS; 10.9 vs. 11.8 months, P = 0.231) did not significantly differ between MONO and COMBO group. In the MONO group, OS was significantly shorter in patients without smoking history compared to those with smoking history [HR for smoking history against non-smoking history: 0.36 (95% CI: 0.16-0.78), P = 0.010]. In the COMBO group, OS was significantly shorter in patients with PS 1 than those with PS 0 [HR for PS 0 against PS 1: 3.84 (95% CI: 1.44-10.20), P = 0.007] and for patients with squamous cell carcinoma (SQ) compared to non-squamous cell carcinoma (non-SQ) [HR for SQ against non-SQ: 0.17 (95% CI: 0.06-0.44), P < 0.001]. For patients with ECOG PS 0 (OS: 26.1 months vs. not reached, P = 0.0031, PFS: 6.5 vs. 21.7 months, P = 0.0436) or non-SQ (OS: 23.8 months vs. not reached, P = 0.0038, PFS: 10.9 vs. 17.3 months, P = 0.0383), PFS and OS were significantly longer in the COMBO group. Conclusions ECOG PS and histological type should be considered when choosing MONO or COMBO treatment in older patients with NSCLC and PD-L1 TPS ≥ 50%.

Abstract
BACKGROUND The long overall survival (OS) observed among patients with non-small cell lung cancer (NSCLC) with high programmed death-ligand 1 (PD-L1) expression in chemoimmunotherapy (CIT) groups in previous phase III trials suggests the limited efficacy of CIT among the subgroup with ≤49% PD-L1 expression on tumor cells. Hence, sequential treatment with first-line platinum-based chemotherapy followed by second-line immune checkpoint inhibitor treatment (SEQ) is an option. This study examined whether first-line CIT would provide better outcomes than SEQ in patients with advanced NSCLC with ≤49% PD-L1 expression. METHODS This retrospective study evaluated patients with untreated NSCLC who received first-line CIT or SEQ at nine hospitals in Japan. OS, progression-free survival (PFS), PFS-2 (the time from first-line treatment to progression to second-line treatment or death), and other related outcomes were evaluated between the CIT and SEQ groups. RESULTS Among the 305 enrolled patients, 234 eligible patients were analyzed: 165 in the CIT group and 69 in the SEQ group. The COX proportional hazards model suggested a significant interaction between PD-L1 expression and OS (p = 0.006). OS in the CIT group was significantly longer than that in the SEQ group in the 1-49% PD-L1 expression subgroup but not in the <1% PD-L1 expression subgroup. Among the subgroup with 1-49% PD-L1 expression, the CIT group exhibited longer median PFS than the SEQ group (CIT: 9.3 months (95% CI: 6.7-14.8) vs. SEQ:5.5 months (95% CI: 4.5-6.1); p < 0.001), while the median PFS in the CIT group was not statistically longer than the median PFS-2 in the SEQ group (p = 0.586). There was no significant difference between the median PFS in the CIT and SEQ groups among the <1% PD-L1 expression subgroup (p = 0.883); the median PFS-2 in the SEQ group was significantly longer than the median PFS in the CIT group (10.5 months (95% CI: 5.9-15.3) vs. 6.4 months (95% CI: 4.9-7.5); p = 0.024). CONCLUSIONS CIT is recommended for patients with NSCLC with 1-49% PD-L1 expression because it significantly improved OS and PFS compared to SEQ. CIT had limited benefits in patients with <1% PD-L1 expression, and the median PFS-2 in the SEQ group was significantly longer than the median PFS in the CIT group. These findings will help physicians select the most suitable treatment option for patients with NSCLC, considering PD-L1 expressions.

Abstract
Endobronchial metastasis (EBM) of hepatocellular carcinoma (HCC) is rare though HCC often metastasizes to the lungs. In this case report, a 74-year-old man with a history of HCC with chronic hepatitis C experienced hemoptysis and a dry cough. During immunotherapy for postoperative recurrent HCC, chest computed tomography (CT) revealed soft tissue shadows in the right upper and lower lobe bronchi, and we pathologically diagnosed as EBM of HCC using bronchoscopy. Although the prognosis of HCC with EBM is poor, lenvatinib, a tyrosine kinase inhibitor, was administered and resulted in improved symptoms, decreased tumour markers, and reduced EBM shadows on chest CT scans. To the best of our knowledge, this is the first case of lenvatinib monotherapy for EBM of HCC. It is important to perform a bronchoscopy for early diagnosis of EBM, followed by lenvatinib treatment.

Abstract
BACKGROUND Durvalumab consolidation after chemoradiotherapy (CRT) is a standard treatment for locally advanced non-small cell lung cancer (NSCLC). However, studies on immunological and nutritional markers to predict progression-free survival (PFS) and overall survival (OS) are inadequate. Systemic inflammation causes cancer cachexia and negatively affects immunotherapy efficacy, which also reflects survival outcomes. PATIENTS AND METHODS We retrospectively investigated 126 patients from seven institutes in Japan. RESULTS The modified Glasgow Prognostic Score (mGPS) values, before and after CRT, were the essential predictors among the evaluated indices. A systemic inflammation-based prognostic risk classification was created by combining mGPS values before CRT, and C-reactive protein (CRP) levels after CRT, to distinguish tumor-derived inflammation from CRT-induced inflammation. Patients were classified into high-risk (n = 31) and low-risk (n = 95) groups, and the high-risk group had a significantly shorter median PFS of 7.2 months and an OS of 19.6 months compared with the low-risk group. The hazard ratios for PFS and OS were 2.47 (95% confidence interval [CI]: 1.46-4.19, p < 0.001) and 3.62 (95% CI: 1.79-7.33, p < 0.001), respectively. This association was also observed in the subgroup with programmed cell death ligand 1 expression of ≥50%, but not in the <50% subgroup. Furthermore, durvalumab discontinuation was observed more frequently in the high-risk group than in the low-risk group. CONCLUSION Combining pre-CRT mGPS values with post-CRT CRP levels in patients with locally advanced NSCLC helps to predict the PFS and OS of durvalumab consolidation after CRT.

Abstract
Background:Belimumab (BEL) is a human monoclonal antibody that specifically inhibits B-cell activating factor (BAFF). PLUTO is an ongoing trial evaluating efficacy and safety of intravenous (IV) BEL in children ≥5 years of age with cSLE. Efficacy, and safety endpoints of PLUTO have been reported;1briefly, numerically more BEL vs PBO pts met the primary and major secondary efficacy endpoints. We present patient (pt) response to BEL over time.Objectives:To evaluate changes in SLE Responder Index (SRI) 4 and SRI6 responses, and disease activity over 52 weeks, in paediatric pts receiving BEL, or placebo (PBO), plus standard SLE therapy (SST).Methods:PLUTO (GSK Study BEL114055,NCT01649765) is a Phase 2, randomised, double-blind, placebo-controlled study. Pts 5–17 years of age with active cSLE were randomised to monthly BEL 10 mg/kg IV, or PBO, plus SST. Endpoints assessed: SRI4 and SRI6 response rate, mean percentage and absolute change from baseline in Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLE Disease Activity Index (SLEDAI) and Physicians’ Global Assessment (PGA) scores, and percentage of pts with no new British Isles Lupus Assessment Group (BILAG) 1A/2B organ domain scores compared with baseline, all by study visit. The last-observation-carried-forward (LOCF) principle (missing values imputed using the last available non-missing value) was applied to pts who withdrew or received protocol-prohibited medication or a dose of allowable medication that resulted in treatment failure prior to the Week (Wk) 52 visit. Descriptive statistics were used.Results:A total of 93 pts (94.6% female, mean [SD] age 14.0 [2.49] years) were randomised for the intention-to-treat (ITT) population: 53 to BEL and 40 to PBO. Mean (SD) BEL and PBO baseline scores were 10.3 (3.34) and 10.4 (3.63) for SELENA-SLEDAI and 1.3 (0.43) and 1.4 (0.42) for PGA, respectively. Pt number with at least BILAG 1A/2B organ domain involvement at baseline was 37 (69.8%) for BEL and 29 (72.5%) for PBO. SRI4 and SRI6 responses over 52 weeks were mostly numerically higher with BEL than PBO; more BEL than PBO pts were SRI4 and SRI6 responders at Wk 52 (Figure 1). Unadjusted mean (SE) percentage changes from baseline over time in SELENA-SLEDAI and PGA scores generally favoured BEL over PBO, as did unadjusted mean (SE) absolute changes (Figure 2). Wk 52 adjusted mean (95% CI) percentage treatment difference vs PBO was -4.0% (-21.8, 13.9) for SELENA-SLEDAI and -6.1% (-23.9, 11.7) for PGA, while Wk 52 adjusted mean (95% CI) treatment difference vs PBO was -0.7 (-2.4, 1.1) for SELENA-SLEDAI and -0.1 (-0.3, 0.1) for PGA. Over the study duration, numerically more BEL than PBO pts had no new BILAG 1A/2B organ domain scores (Figure 2).Figure 1.SRI4 and SRI6 response by study visitFigure 2.SELENA-SLEDAI and PGA score mean percentage and absolute change from baseline, and no new BILAG 1A/2B organ domain scores compared with baseline, all by study visitConclusion:In line with the main analyses performed at Wk 52,1further analyses of responses over time in SRI4, SRI6 and disease activity generally favoured BEL over PBO. Combined, these results continue to support the efficacy profile of IV BEL in the treatment of children with cSLE.References:[1]Brunner HI,et al.Arthritis Rheumatol.2018;70(59): 3224–5, Abst. 2867Acknowledgments:We acknowledge all PLUTO investigators (PRINTO, PRCSG and otherwise affiliated).

Abstract
AIMS Multiple system atrophy (MSA) is pathologically characterized by the formation of α-synuclein-containing glial cytoplasmic inclusions (GCIs) in oligodendrocytes. However, the mechanisms of GCI formation are not fully understood. Cellular machinery for the formation of aggresomes has been linked to the biogenesis of the Lewy body, a characteristic α-synuclein-containing inclusion of Parkinson's disease and dementia with Lewy bodies. Here, we examined whether GCIs contain the components of aggresomes by immunohistochemistry. METHODS Sections from five patients with MSA were stained immunohistochemically with antibodies against aggresome-related proteins and analysed in comparison with sections from five patients with no neurological disease. We evaluated the presence or absence of aggresome-related proteins in GCIs by double immunofluorescence and immunoelectron microscopy. RESULTS GCIs were clearly immunolabelled with antibodies against aggresome-related proteins, such as γ-tubulin, histone deacetylase 6 (HDAC6) and 20S proteasome subunits. Neuronal cytoplasmic inclusions (NCIs) were also immunopositive for these aggresome-related proteins. Double immunofluorescence staining and quantitative analysis demonstrated that the majority of GCIs contained these proteins, as well as other aggresome-related proteins, such as Hsp70, Hsp90 and 62-kDa protein/sequestosome 1 (p62/SQSTM1). Immunoelectron microscopy demonstrated immunoreactivities for γ-tubulin and HDAC6 along the fibrils comprising GCIs. CONCLUSIONS Our results indicate that GCIs, and probably NCIs, share at least some characteristics with aggresomes in terms of their protein components. Therefore, GCIs and NCIs may be another manifestation of aggresome-related inclusion bodies observed in neurodegenerative diseases.

Abstract
Prostaglandin (PG) F(2α) is one of the major prostanoids biosynthesized by cyclooxygenases (COXs) from arachidonic acid. Although it has been reported that there is a selective surge in PGF(2α) production in the hippocampus during kainic acid (KA)-induced seizure activity, the precise intra-hippocampal distribution of PGF(2α) has not been elucidated due to the paucity of effective histological techniques for detecting PGs in tissues. We investigated the tissue distribution of PGF(2α) in the rat hippocampus 30 min after KA injection by developing fixation and immunohistological-staining methods. To detect PGF(2α) directly on histological sections, we used systemic perfusion fixation with water-soluble carbodiimide fixative, followed by immersion of the brains in Zamboni's fixative. We then performed immunofluorescence staining with anti-PGF(2α) antibody, with negative control experiments used to confirm the staining specificity. Definitive immunolabeling for PGF(2α) was evident most markedly in pyramidal cells of the hippocampal cornu Ammonis (CA) 3 sector and neurons of the hilus in KA-treated rats. Immunolabeling for PGF(2α) was also evident in granule cells of the dentate gyrus. Double immunfluorescence staining revealed that PGF(2α)-immunopositive neurons expressed cytosolic phospholipases A(2), COX-2, and FP receptor. These results suggest that the major source of PGF(2α) production immediately after KA injection was neurons of the hippocampal CA3 sector, hilus and dentate gyrus. These neurons exert PGF(2α)-mediated functions via FP receptors in an autocrine/paracrine manner and may play pathophysiological roles in the acute phase (30 min) of excitotoxicity.

Abstract
Objectives:Systemic juvenile idiopathic arthritis (sJIA) is a rheumatic disease in childhood characterised by systemic symptoms and a relatively poor prognosis. Peripheral leukocytes are thought to play a pathological role in sJIA although the exact cause of the disease is still obscure. In this study, we aimed to clarify cellular functional abnormalities in sJIA.Methods:We analysed the gene expression profile in peripheral leukocytes from 51 patients with sJIA, 6 patients with polyarticular type JIA (polyJIA) and 8 healthy children utilising DNA microarrays. Gene ontology analysis and network analysis were performed on the genes differentially expressed in sJIA to clarify the cellular functional abnormalities.Result:A total of 3491 genes were differentially expressed in patients with sJIA compared to healthy individuals. They were functionally categorised mainly into a defence response group and a metabolism group according to gene ontology, suggesting the possible abnormalities in these functions. In the defence response group, molecules predominantly constituting interferon (IFN)γ and tumour necrosis factor (TNF) network cascades were upregulated. In the metabolism group, oxidative phosphorylation-related genes were downregulated, suggesting a mitochondrial disorder. Expression of mitochondrial DNA-encoded genes including cytochrome c oxidase subunit 1(MT-CO1) and MT-CO2 were suppressed in patients with sJIA but not in patients with polyJIA or healthy children. However, nuclear DNA-encoded cytochrome c oxidases were intact.Conclusion:Our findings suggest that sJIA is not only an immunological disease but also a metabolic disease involving mitochondria disorder.

Abstract
Interleukin (IL)-18 production and pulmonary function were evaluated in patients with chronic obstructive pulmonary disease (COPD) in order to determine the role of IL-18 in COPD. Immunohistochemical techniques were used to examine IL-18 production in the lungs of patients with very severe COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage IV, n = 16), smokers (n = 27) and nonsmokers (n = 23). Serum cytokine levels and pulmonary function were analysed in patients with GOLD stage I-IV COPD (n = 62), smokers (n = 34) and nonsmokers (n = 47). Persistent and severe small airway inflammation was observed in the lungs of ex-smokers with very severe COPD. IL-18 proteins were strongly expressed in alveolar macrophages, CD8+ T-cells, and both the bronchiolar and alveolar epithelia in the lungs of COPD patients. Serum levels of IL-18 in COPD patients and smokers were significantly higher than those in nonsmokers. Moreover, serum levels of IL-18 in patients with GOLD stage III and IV COPD were significantly higher than in smokers and nonsmokers. There was a significant negative correlation between serum IL-18 level and the predicted forced expiratory volume in one second in patients with COPD. In contrast, serum levels of IL-4, IL-13 and interferon-gamma were not significantly increased in any of the three groups. In conclusion, overproduction of interleukin-18 in the lungs may be involved in the pathogenesis of chronic obstructive pulmonary disease.

Abstract
OBJECTIVE To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD). METHODS Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centre. Secondly, international consensus was reached on the content of the website. Finally, the website was developed and the texts translated. RESULTS The web page contains three main sections: (a) description for families of the characteristics of 15 PRD; (b) list of paediatric rheumatology centres; (c) contact information for family self help associations. A version for 45 countries in 52 languages (with another three in progress) is now available on the web. 291 surveys from 171 centres and 102 family associations were received from 42 countries. The median proportion of time spent in paediatric practice in the centres examined was 100%, with 70% of this time dedicated to paediatric rheumatology. 90% of the centres were willing to perform clinical trials in the future. CONCLUSIONS The PRINTO/PRES website provides a well defined and competent set of information about PRD, with appropriate multiple translated versions and easy web navigational direction.

Abstract
OBJECTIVE To evaluate the safety and efficacy of L-asparaginase as an immunosuppressive agent in a mouse model of rheumatoid arthritis. METHODS Male DBA/1 mice with collagen-induced arthritis (CIA) were treated at different intervals with various doses of native and pegylated L-asparaginase from E. coli. The mice were observed for 4 weeks during which time arthritis was scored. Outcome parameters included effect on severity and progression of established arthritis as well as prevention of disease. In addition, X-rays from the affected joints were obtained for comparison. RESULTS Both native L-asparaginase at a dose of 50 IU/injection intraperitoneally three days a week and pegylated asparaginase (PEG-L-asparaginase) at a dose of 25 IU/injection twice a week, significantly reduced the mean arthritic score (MAS) in mice with established arthritis (p < 0.001 for PEG-L-asparaginase). When native L-asparaginase was administered before the onset of arthritis (days 14-post immunization) the number of mice developing arthritis as well as the number of arthritic paws and the severity of arthritis in the treatment group were significantly decreased (p < 0.0001). Significant differences were found in the X-ray evaluation between treated and control mice. None of the animals died due to drug related events or showed signs of asparaginase induced toxicity. CONCLUSION Our data provide the first direct evidence that L-asparaginase is a potent antiarthritic agent and may represent an effective second line agent for future treatment studies in juvenile and adult rheumatoid arthritis.

Abstract
In Sjögren syndrome, purpura is one of its various well known eruptions. Although this disease state is assumed to be based on hypergammaglobulinemia, the details of its mechanism are unknown. We experienced a case involving a female patient with primary Sjögren syndrome showing repeated purpura on the legs, and examined her blood viscosity and histopathology. This girl developed Sjögren syndrome and was admitted to our hospital at 12-years-old. She underwent steroid treatment because of aggravation of the xerosis state and prominent purpura on the legs. Hypergammaglobulinemia was improved during the course; however, purpura appeared repeatedly. Although her blood viscosity was slightly higher than normal, this had no relation to purpura and serum gamma globulin values. Skin biopsy revealed necrotizing angiitis. These results suggest that the purpura of this case was caused not only by hyperviscosity from the hypergammaglobulinemia but also involvement of vasculitis by the primary disease.

Abstract
[structure: see text]. Michael addition of various enolates toward gamma-CH(3-n)F(n)-alpha,beta-unsaturated ketones (n = 1-3) was proven to smoothly furnish the 1,4-adducts with high si face selectivities which monotonously decreased by reduction in the number of fluorines. Although the Felkin-Anh model correctly anticipates the present stereochemical outcome only with E-acceptors, the hyperconjugative stabilization of transition states by electron donation from the allylic substituents (the Cieplak rule) successfully explains the pi-facial preference of both acceptors at least in a qualitative level.

Abstract
OBJECTIVE To evaluate safety and efficacy of high dose etanercept (> 0.8 mg/kg, maximum 25 mg subcutaneously twice weekly) (Enbrel) in children with juvenile rheumatoid arthritis (JRA) and inadequate prior response to standard dose etanercept. METHODS Retrospective chart review of 8 children (6 girls, 2 boys, mean age 8.4 yrs, range 5-16 yrs). Five children had systemic onset, polyarticular course JRA; 2 had polyarticular onset; and one had pauciarticular onset, polyarticular course JRA. All children had failed at least 3 mo (mean 9 mo) treatment with standard dose etanercept (0.4 mg/kg SC twice a week). All 8 children had increase in the etanercept dose to at least 0.8 mg/kg (mean 1.1 mg/kg, maximum 25 mg SC twice weekly) for a mean of 7 mo (range 3-10 mo). Efficacy of high dose etanercept was evaluated by changes in joint count, laboratory data, and ability to decrease concomitant medication. RESULTS Improvements in the joint count and laboratory findings (erythrocyte sedimentation rate, hemoglobin and platelet count) were observed in 2 of 8 (25%) children. In these 2, concomitant prednisone was reduced or discontinued. In contrast, no changes in disease activity or laboratory findings were observed in the other 6 children. Overall, high dose etanercept was well tolerated. No laboratory abnormalities were detected and no child withdrew because of adverse events. CONCLUSION High dose etanercept is safe and well tolerated in children, but efficacy seems limited. In children with unsatisfactory response to standard dose etanercept, an increased dose or treatment prolongation may not offer any additional benefit.

Abstract
OBJECTIVE To evaluate the safety and efficacy of the tumor necrosis factor fusion protein etanercept in children with treatment-resistant uveitis. METHODS Ten children with chronic active uveitis (7 girls and 3 boys, mean age 7.5 years [range 3-12 years]) were enrolled in this prospective study. In 7 children, uveitis was associated with pauciarticular juvenile rheumatoid arthritis. Five children were antinuclear antibody positive. All patients had failed previous therapy with topical steroids and methotrexate and/or cyclosporine. All were treated with etanercept at a dosage of 0.4 mg/kg twice weekly for the first 3 months, and then, if eyes did not improve, with 25 mg twice weekly (mean 1.1 mg/kg) for at least 3 additional months. RESULTS At the beginning of the trial, uveitis affected 18 eyes in the 10 children. Within 3 months, 10 of 16 affected eyes (63%; P = 0.017) showed a rapid decrease in anterior chamber cell density, including remission of uveitis in 4 eyes. In children with visual acuity of less than 20/25, 4 of 10 eyes (40%) improved. An exacerbation of uveitis during etanercept therapy occurred in only 1 child (1 of 14 eyes [7%]). Other ocular outcome parameters, such as intraocular pressure, synechia formation, and lens clarity, remained unchanged. Following a dosage increase to an average of 1.1 mg/kg after 3 months in 7 children, no further improvement was noted. CONCLUSION Our data suggest that etanercept injected subcutaneously twice a week has a beneficial effect on treatment-resistant chronic uveitis in children. Further controlled studies with etanercept in systemic or topical form are necessary to confirm its efficacy and optimal mode of administration.

Abstract
Results of reflection microscopy and local reflection spectroscopy of J-aggregates of two pseudoisocyanine dyes in a thin film polymer matrix are reported. The individual J-aggregates assemble into fibre-like shapes of large structural heterogeneity. Reflectance spectra obtained at different samples, different locations on one sample and even at different positions of the same aggregate fibre reveal a wide distribution of optical properties. The shapes and absolute reflectivities of the spectra are suggested to originate from varying strengths of exciton-photon interaction and from the effect of finite thickness of the aggregate fibres. Polarization dependence measurements of local reflectivities provide orientations of the exciton transition dipole moments at 572 nm and 540 nm with respect to the orientation of the aggregate fibres. Furthermore, modified synthesis of capped semiconductor nanocrystals of CdSe is presented. The method yields high quality quantum dots suitable for microscopic imaging and spectroscopy.

Abstract
OBJECTIVE To investigate the prevalence of anti-alpha-fodrin antibody specific for adult Sjögren's syndrome (SS) in patients with juvenile onset SS. METHODS Serum anti-alpha-fodrin antibody was examined in 15 patients with juvenile SS (11 cases of primary SS and 4 secondary SS) and in 16 children with systemic lupus erythematosus (SLE) by Western blot analysis using a recombinant 120 kDa alpha-fodrin fusion protein. RESULTS All the 15 serum samples from patients with SS reacted with a recombinant alpha-fodrin fusion protein in Western blot analysis. In contrast, reactivity was found in only 2 of the 16 patients with SLE. The clinical features of the 15 patients with juvenile onset SS were very specific; only 4 patients complained of dryness, while 6 had abnormal excretion ability. Salivary gland enlargement was the most common clinical manifestation. Characteristic laboratory findings in juvenile onset SS included a higher prevalence of antinuclear antibodies, anti-SSA/Ro antibodies, and rheumatoid factor, as well as increased erythrocyte sedimentation rate and hypergammaglobulinemia. CONCLUSION The pathogenesis of juvenile SS seems to be the same as that of adult SS, although subjective symptoms of dryness are less frequent in juvenile cases. This discrepancy may indicate that SS is a slowly progressive disease with a long time span. The anti-alpha-fodrin antibody is likely to be a reliable diagnostic marker for juvenile SS.

Abstract
From September 1995 through May 1999, percutaneous endoscopic gastrostomy (PEG) was performed in 47 elderly patients, aged 65 to 93 (average 78.9). Several treatments were additionally performed to prevent serious complications in these cases, and their usefulness and problems were investigated. Gastropexy was performed to prevent peritonitis in cases of self-removal of tubes in the acute stage. Intraoperative fluoroscopy was used prevent perforation of the intestines. However, re-insertion of the endoscopic, which was necessary with the push method, was omitted to reduce the burden on the patients. In patients with tube troubles in the chronic stage such as the buried bumper syndrome or self-removal, the existing fistula was preserved and the gastrostomy was reconstructed using a narrow polyvinyl chloride tube and a flexible guide wire to prevent peritonitis by erroneous insertion of the tube. In terms of results, gastropexy was useful to prevent peritonitis in one patient with early self-removal of the tube. Data to evaluate the usefulness of fluoroscopy in preventing perforation of the intestine were insufficient, so more patients need to be studied in the future. Even when confirmation of the location of the internal bumper by endoscopy was omitted, there was no case of poor traction of the bumper, so this procedure seems unnecessary. Review of tube troubles, in the chronic stage revealed no case of peritonitis caused by erroneous insertion of tubes or erroneous injection of nutrients with our reconstruction methods, and complete reconstruction of the gastrostomy with preservation of the existing fistula appeared to be possible. However, those additional treatments require extension of the operation time and rise in cost with increased use of medical instruments, so the indications should be carefully considered.

Abstract
The effect of a male steroid hormone, 5DHT, on the expression of TNF-alpha was examined using a human leukemia T cell line, Jurkat. Cells were treated with 5DHT in the presence or absence of PHA, and RNA was isolated followed by a reverse transcriptase - mediated PCR (RT-PCR) to measure the steady state levels of TNF-alpha mRNA. The treatment of cells with 5DHT resulted in a 50% of decrease in the level of TNF-alpha mRNA compared to that in untreated conditions (basal level). A similar level of reduction of the message by 5DHT was also observed in PHA-stimulated cells. The reduction of the steady state levels of TNF-alpha mRNA in Jurkat cells was a result of destabilization of the gene as demonstrated by actinomycin D treatment; a half-life of TNF-alpha message in 5DHT treated cells and non-treated cells was 1 hr and 2.5 hr, respectively, whereas that in 5DHT/PHA and PHA-treated cells was 3hr and 6hr, respectively.

Abstract
OBJECTIVE The aim of this study is to describe the long-term outcome of preserved hearing after vestibular schwannoma surgery. METHODS Subjects are 20 unilateral vestibular schwannoma patients whose class A hearing of the AAO-HNS classification was preserved successfully after tumor removal. Hearing preservation surgery was attempted via the middle cranial fossa (MCF) or the extended MCF approach. The follow-up periods ranged from 2 to 16 years. The outcome measures included the pure tone average (PTA) and speech discrimination score (SDS). RESULTS PTA was maintained in less than 30 dB in 11 out of 20 patients within 2 years follow-up, six out of 13 patients within 4 years follow-up, and two out of five patients within 6 years follow-up, respectively. SDS was maintained in more than 70% in 17 out of 20 patients within 2 years follow-up, ten out of 13 patients within 4 years follow-up, and three out of five patients within 6 years follow-up, respectively. CONCLUSIONS The preserved hearing maintained about more than 40% of the patients with the class A hearing in every 2 years follow-up. From this result, we can conclude that the hearing preservation surgery could be one of the best treatments for vestibular schwannoma patients with class A hearing. However, further study will be needed to clarify the mechanism of the deterioration in hearing after hearing preservation surgery.

Abstract
OBJECTIVE To investigate the relevance of vascular endothelial growth factor (VEGF) in the pathogenesis of juvenile rheumatoid arthritis (JRA). METHODS Serum VEGF levels in 58 patients with JRA (systemic in 17, polyarticular in 29, pauciarticular in 12) were measured by ELISA and compared with those of 21 patients with infectious diseases and 50 healthy children. Correlations of VEGF levels with number of joints with active arthritis, erythrocyte sedimentation rate (ESR), and hyaluronic acid (HA) were examined. RESULTS Serum levels of VEGF in patients with JRA were significantly higher than in healthy controls. Patients with systemic and polyarticular JRA showed statistically higher levels of VEGF than those with infectious diseases. VEGF levels correlated statistically with C-reactive protein (CRP) in patients with both infectious diseases and polyarticular JRA, but the regression slope (VEGF/CRP) was much steeper in polyarticular JRA than in infectious diseases. Serum VEGF levels correlated with disease activity variables such as the number of joints with active arthritis, ESR, and serum HA levels in polyarticular JRA. CONCLUSION The correlation of serum VEGF levels and disease activity in polyarticular JRA suggests that VEGF may take an active part in joint inflammation.

Abstract
An eleven-year-old boy with systemic lupus erythematosus (SLE) developed severe bilateral lupus retinopathy when he was in active stage of SLE. The patient, who had suffered from SLE for 3 years, was admitted to our hospital because of high grade fever, systemic lymphadenopathy, leukopenia, elevation of erythrocyte sedimentation rate and hypocomplementemia. The dose of prednisolone was increased considering he was exacerbated of SLE, however, the convulsion as CNS lupus occurred to him. After the event he noted loss of vision in his bilateral eyes. The ophthalmologic examination revealed the lesions of cotton-wool spots, retinal vessel dilatations and diffuse occlusions of the retinal arterioles and venules which were compatible with lupus retinopathy. Although the coagulation time was normal, antiphospholipid antibodies were positive at the time of ocular involvement. Careful attention should be paid to the occurrence of lupus retinopathy when the patients with SLE developed in the active stage or CNS lupus, especially they have antiphospholipid antibodies.

Abstract
Vascular endothelial growth factor (VEGF) is an angiogenic mitogen that specifically targets vascular endothelial cells. The objective of this study was to evaluate the role of VEGF in Kawasaki disease (KD), the most common cause of systemic vasculitis in childhood. Serum VEGF levels were measured by ELISA in 22 patients with KD, 22 febrile children with infection, and 19 healthy children. Samples from KD patients were divided into three groups: acute stage (n = 20), subacute stage (n = 13), and convalescent stage (n = 15). The results showed that KD patients in the acute and subacute stages had significantly higher levels of VEGF than did patients with infectious diseases and the healthy control subjects. When compared with the VEGF levels of patients with and without coronary artery lesions (CAL), significantly higher levels of VEGF were observed in the subacute stage in patients with CAL and in patients without CAL in the acute stage. Serial examination revealed that the serum VEGF levels in KD patients with CAL increased from a relatively low level in the acute stage to an extremely high level in the subacute stage. In contrast, patients without CAL were found to have extremely high levels of VEGF only in the acute stage of KD. In KD patients, the serum VEGF levels did not correlate with the inflammatory markers and clinical symptoms. Our results raise the possibility that VEGF is involved in the pathogenesis of KD, especially in the development of CAL. Further study is needed to clarify the biologic effect of VEGF on coronary arteries in KD.

Abstract
Superantigens (SAs) are known to induce transient anergy followed by T cell activation. Recent reports have suggested that SAs are involved in the pathogenesis of Kawasaki disease (KD). In the present study, we investigated the peripheral T cell response to SAs by measuring proliferation and IL-2 production to determine whether the T cell anergy is induced by SAs in patients with KD. T cells were obtained from 45 Japanese patients with KD in different stages of the disease and were stimulated by streptococcal pyrogenic exotoxin (SPE)-A, SPE-C, and toxic shock syndrome toxin-1 (TSST-1). T cells from patients with KD in the acute or convalescent stage up to 2 mo showed significantly lower proliferation and IL-2 production than did T cells from healthy control subjects stimulated by SPE-C, but not SPE-A or TSST-1. The T cell response to SPE-C normalized within 1 y. The low T cell response to SPE-C in the acute stage correlated with a peak platelet count and the C-reactive protein-positive period. These findings suggest that the transient low T cell response to SPE-C in patients with KD may have been related to SA-induced anergy or disappearance of SPE-C-responding cells from the circulation. The present results suggested that SPE-C may be involved in the pathogenesis of KD.

Abstract
BACKGROUND It is well known that many diseases may be associated with obesity resulting from an energy-rich diet, and that a westernized diet may increase the incidence of urinary stone formation. To evaluate degree of obesity, we investigated body mass index (BMI) in patients with calcium containing upper urinary stones and examined their blood with regard to lipid metabolism. METHODS Between July 1994 and December 1995, we analyzed 332 fresh renal-stone formers (253 males and 79 females) who visited 7 hospitals located in Ehime prefecture. As a control, 949 residents older than 20 years (387 males and 562 females) of the same prefecture were also examined by the annual Ehime prefecture office report of 1994. Body mass index as degree of obesity, stone-recurrence, blood test and other complicated diseases were examined. RESULTS In male stone formers the rate of obesity was significantly higher than that of control males (p < 0.001). The differences were seen only in their twenties and fifties. Furthermore, among male stone formers the rate of obesity was significantly higher in recurrent stone formers than in single stone formers (p < 0.05). On the other hand, in female, there was no significant difference in the rate of obesity between stone formers and controls. No difference was seen between recurrent stone formers and single stone formers. In the blood test, there was no differences in the level of calcium, phosphate and uric acid between stone formers and controls. The level of cholesterol and triglyceride in male were significantly higher in controls (p < 0.01) and there was no difference in the level of high density lipoprotein (HDL) between stone formers and controls. Among the stone formers, 48 males (20.0%) and 17 females (21.5%) had other diseases. The rate of complicated diseases was similar to that of controls and no specific diseases in the stone formers were identified. CONCLUSION Our report suggested that obesity in male should be considered as a risk factor for calcium containing stone formation.

Abstract
Although the shortest (class I) minisatellite (i.e., variable number of tandem repeats [VNTR]) alleles in the 5' region of the insulin gene are positively associated with IDDM in Caucasians, the majority of Japanese are homozygous for class I alleles. Here, we determined the exact length, in number of repeat units (RUs), of class I alleles in Japanese subjects. The distribution of class I alleles in Japanese was trimodal, with peaks located at 32/33, 41, and 44 RUs. The shortest component (i.e., 1S [25-38 RUs]) alleles were significantly increased in the IDDM group compared with the control group (54 vs. 46%; P = 0.040). The 1S/1S genotype was significantly increased in the IDDM patients (34 vs. 20%; P = 0.005; relative risk 2.1). Furthermore, the transmission disequilibrium test of Japanese families with 1S/1M or 1S/1L heterozygous parents confirmed the association of 1S alleles; 17 alleles of 1S and 6 alleles of 1M (39-41 RUs) or 1L (42-44 RUs) were transmitted to affected offspring (P = 0.022). In addition, we found tight linkage of 1S with allele 9 of the tyrosine hydroxylase gene microsatellite and allele (-) of the IGF-II gene Apa I polymorphism, but neither 9 nor (-) alleles were significantly associated with IDDM. The present study suggests that a class I subset may have a role in IDDM susceptibility in Japan. It was revealed that the difference between 1S alleles and 1M or 1L alleles is almost consistently characterized by a sequence variation generated by deletion of two copies of an ACAGGGGTCC CGGGG repeat element, implying that sequence variation of class I alleles may influence disease susceptibility.

In order to discuss the diversity of clinical features and the difficulty in diagnosis of children with juvenile rheumatoid arthritis (JRA), we present two cases who have documented the development of systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) after a long period of disease characterized only by arthritis that was initially diagnosed as JRA. The first case was a girl diagnosed for her arthritic joints as polyarticular JRA at 15 years of age. At onset, she had Raynaud phenomenon but autoantibodies such as anti-nuclear antibody (ANA), anti-DNA antibody, and rheumatoid factor were negative. Five years after onset, she became ANA positive and 3 years later she became pregnant. During her pregnancy, she became positive for anti-DNA antibody without any signs of nephritis. One month after the delivery, however, she developed butterfly rash, carditis, nephritis, and was diagnosed as SLE. No destructive changes were observed in her joints though arthritis continued for 8 years form onset to pregnancy. The second case was a 3 years old girl who was diagnosed as polyarticular JRA. Treatment by aspirin induced complate remission after one year from the onset. However, 10 years after that remission, she developed Raynaud phenomenon and arthralgia in her knees and hip joints. Her laboratory findings showed hypergammaglobulinemia, positive ANA, positive anti-DNA antibody, positive anti-RNP antibody. She was eventually diagnosed as MCTD when she was found to have polymyositis by EMG and serum CK. In the present paper, two cases imply the difficulty in diagnosing JRA and diversity of rheumatic diseases such as JRA, SLE and MCTD. Closer and longer period of observation is essential for the JRA patients with nondestructive arthritis.

Abstract
BACKGROUND Histamine has a particular role in the pathogenesis of bronchial asthma, and many antiallergic drugs have been developed with antihistaminic action in mind. Recently, a sensitive and specific assay for measuring histamine and its metabolites has been developed. There are, however, no reports of the effect of antiallergic drugs on histamine levels in asthmatic patients. OBJECTIVES To determine the relationship between clinical symptoms and histamine levels in asthmatic patients receiving an antiallergic agent. METHODS A prospective study was designed in asthmatic children treated with azelastine hydrochloride. The evaluation of clinical symptoms was based on scores of the severity of exacerbations, activities of daily living, quality of sleep, and required therapy. Urinary excretion of N-methylhistamine, a major metabolite of histamine, was measured by double antibody radioimmunoassay. RESULTS In the patients treated with azelastine, the improvement in clinical symptoms of bronchial asthma correlated significantly with a decrease in urinary N-methylhistamine excretion (r2 = 0.434, P < .001), while no such relationship was noted in patients receiving no antiallergic agent. Urinary N-methylhistamine excretion showed no diurnal change or influence of meals. CONCLUSIONS Decreased urinary N-methylhistamine excretion may be a direct reflection of the antihistaminic action of azelastine in vivo. Measurement of urinary N-methylhistamine excretion can be used to evaluate the efficacy of agents with antihistaminic action in the treatment of bronchial asthma.
