Background: The purpose of this study was to clarify disease control and medication use among Japanese adult asthmatic patients. Method: We studied the reality of adult outpatients and inpatients with asthma at 26 national hospitals across Japan who visited the clinic between September and October 2006. Anti-asthma medication use and asthma control were assessed. Disease severity was determined according to the 2006 Japanese Guideline, The results of this study were compared with those obtained in 1995 after standardization by age and gender. Results: Of 2524 patients, the prevalence of inhaled corticosteroid use in 2006 was 89%, which was higher than that in 1995 (62%). Although the prevalence of patients who experienced asthma hospitalization once or more in their lifetime in 1995 was 73%, that in 2006 decreased to 49%. The prevalences of hospitalization and unscheduled doctor visit in the last 12 months in 2006 were 8% and 25% respectively. The percentage of patients in 2006 who did not reach an acceptable level of control despite treatment at step 4 of the 2006 Japanese guideline was 15%. Conclusions: A favorable change in asthma medication use and asthma control was observed from 1995 to 2006; that is, increased prevalence of inhaled corticosteroid use and decreased prevalence of patients who experienced hospitalization for asthma once or more in their lifetime. However, some patients remained symptomatic despite high-dose inhaled corticosteroid treatment © 2010 Japanese Society of Allergology.

A prospective study was made to seek for a convenient biomarker to predict progression of bone destruction (PBD) in early stages of rheumatoid arthritis (ERA). All participated patients had definite RA and their radiographic stages were mild less than stage II of the Steinbrocker classification, naïve for treatment of any DMARDs or corticosteroids. After the entry, they were treated according to the 2002 ACR management guideline for RA. The candidate biomarkers (RF-IgM, RF-IgG, CARF, ACPA, CRP, ESR, NTx, MMP-3, IL-6 and osteopontin) were measured at the entry. PBD was assessed radiographically by interval changes in the modified Sharp scores (ΔSHS) for 24 months. The associations between ΔSHS and baseline biomarkers were assessed statistically by multivariate regression analyses. Both the baseline ACPA and IL-6 levels correlated with PBD, suggesting that they could predict PBD in ERA. © 2012 Springer-Verlag.

Background Though various clinical conditions of aspergillosis can occur, depending essentially on the host's immunological status, the focus of research in North American and European countries has mainly been on invasive pulmonary aspergillosis in immunocompromised patients. There are, however, also many problems to overcome in chronic forms of aspergillosis. One of those problems is that there are no codified treatment guidelines for chronic pulmonary aspergillosis (CPA). Especially in Japan, this issue is more serious, because there are more cases with CPA due to the many aged people with past history of tuberculosis. Several clinical cases and case series have reported the usefulness of the various antifungal agents that are available. The new triazole, voriconazole, in particular, seems to be effective in the treatment of CPA. The aim of the present study is to evaluate the efficacy and safety of voriconazole in the treatment of CPA in non-immunocompromised patients. Patients and methods We conducted a prospective, openlabel, non-comparative, multicenter study over a 2-year period. For inclusion in the study, patients with confirmed or probable CPA were recruited in 11 hospitals of the National Hospital Organization in Japan. Clinical, radiological, serological, and mycological data were collected at baseline and 12 weeks after treatment or at the end of treatment. Results Among 77 patients enrolled in the study, 71 patients (mean age 65.9 years, 56 males and 15 females) were eligible for the study. All of the eligible patients presented with underlying lung diseases, including sequelae of tuberculosis (n = 35), non-tuberculous mycobacterial lung disease (n = 8), chronic obstructive pulmonary disease (COPD) (n = 8), interstitial pneumonia (n = 7), cystic lung disease (n = 4), pneumothorax (n = 3), bronchial cancer (n = 1), and others (n = 5). Voriconazole was indicated in 48 cases (68 %) as the first-line treatment for CPA and 23 patients previously received other antifungal therapies. Based on a composite of clinical, radiologic, serological, and mycologic criteria, good response was seen in 43 patients (60.6 %), no response was observed in 19 patients (26.8 %), and 4 cases (5.6 %) got worse. Five patients (7.0 %) were unassessable for efficacy. The common adverse events were visual disturbances (17 patients 23.9 %), abnormal liver function test results (12 patients, 16.9 %), adverse psychological effects (3 patients, 4.2 %), and others (10 patients, 14.0 %). Treatment with voriconazole had to be stopped in 2 cases (2.8 %) because of serious adverse events (abnormal liver function test results). There was no association between adverse effects and trough voriconazole levels in serum. Conclusions In Japan, voriconazole provides effective therapy of CPA in non-immunocompromised patients with an acceptable level of toxicity. © Springer-Verlag 2012.

Background: Although cisplatin-based chemotherapy combined with thoracic irradiation (TRT) is a standard treatment for unresectable, locally advanced non-small cell lung cancer (NSCLC), this treatment outcome has remained unsatisfactory. We had previously conducted a phase I trial of cisplatin plus S-1, an oral 5-fluorouracil derivative, and TRT, which were safe and effective. Methods: In this phase II trial, 48 patients with stage III NSCLC received cisplatin (40mg/m2 on days 1, 8, 29 and 36) and S-1 (80mg/m2 on days 1-14 and 29-42) and TRT (60Gy). The primary endpoint was the response rate. Results: A partial response was observed in 37 patients (77%; 95% confidence interval: 63-88%). At a median follow up of 54 months, the median progression-free survival and median survival time were 9.3 and 31.3 months, respectively. No difference in efficacy was observed when the patients were stratified by histology. Toxicities were generally mild except for grade 3 or worse febrile neutropenia and pneumonitis of 8% and 4%, respectively. No patient developed severe esophagitis. At the time of this analysis, 35 (73%) of the 48 patients recurred; 15 (31%) showed distant metastasis, 17 (35%) had loco-regional disease, and 2 (4%) showed both loco-regional disease and distant metastasis. Conclusions: This chemoradiotherapy regimen yielded a relatively favorable efficacy with mild toxicities in patients with locally advanced NSCLC. © 2014 Elsevier Ireland Ltd.

Background. Chemoradiation improves survival for patients with locally advanced non-small cell lung cancer (NSCLC), but clinical outcomes beyond five years are rarely reported. The aim of the present study was to identify the long-term results of a phase II study of docetaxel and cisplatin with concurrent thoracic radiation. Methods. We previously reported short-term outcomes from the phase II study, which enrolled 42 patients (aged ≤ 75 years) with unresectable stage III NSCLC. We continued to follow these patients for long-term clinical outcomes. Results. At a median follow-up for all patients of 6.3 years (range: 5.27.1 years), the median survival time was 2.1 years and the actual five-year survival rate was 31%. Among 14 patients who were progression-free longer than two years, three patients died due to bacterial or fungal pneumonia and one died due to gall bladder cancer. Conclusions. Thirty-one percent of locally advanced patients having NSCLC treated with docetaxel and cisplatin and concurrent thoracic radiation survived beyond five years. Progression-free patients might be cautiously followed up taking precautions against emerging pneumonia. © 2012 Informa Healthcare.

Background. The survival advantage achieved by existing anti-cancer agents as second-line therapy for relapsed non-small cell lung cancer (NSCLC) is modest and further improvement of treatment outcome is desired. Combination chemotherapy with irinotecan and amrubicin for advanced NSCLC has not been fully evaluated. Methods. The primary endpoint of this phase II clinical trial was objective response. Patients with NSCLC who had been treated previously with one or two chemotherapy agents were enrolled. Irinotecan and amrubicin were both administered on Days 1 and 8 of a 21-day cycle, at doses of 100 mg/m2 and 40 mg/m2, respectively. Results. Between 2004 and 2006, 31 patients received a total of 101 courses; the median number of courses administered was three (range, one to six). Objective response was obtained in nine of the 31 patients (29.0% response rate; 95% confidence interval (CI), 12.1-46.0%). With a median follow-up time of 43.9 months, median survival time and the median progression-free survival time were 14.2 and 4.0 months, respectively. Myelosuppression was the most frequently observed adverse event, with grade 3/4 neutropenia in 51% of patients. Febrile neutropenia developed after nine courses (9%) and resulted in one treatment-related death. Cardiac toxicity and diarrhea, possibly specific for both agents, were infrequent and manageable. Conclusion. Combination chemotherapy with irinotecan and amrubicin is effective in patients with NSCLC but showed moderate toxicities in second- or third-line settings. © 2012 Informa Healthcare.

Backgrounds: Chemotherapy is a mainstay in the treatment of extensive-disease small-cell lung cancer (ED-SCLC), although the survival benefit remains modest. We conducted a phase II trial of amrubicin (a topoisomerase II inhibitor) and topotecan (a topoisomerase I inhibitor) in chemotherapy-naïve and relapsed SCLC patients. Methods: Amrubicin (35mg/m 2) and topotecan (0.75mg/m 2) were administered on days 3-5 and 1-5, respectively. The objective response rate (ORR) was set as the primary endpoint, which was assessed separately in chemotherapy-naïve and relapsed cases. Results: Fifty-nine patients were enrolled (chemotherapy-naïve 31, relapsed 28). The ORRs were 74% and 43% in the chemotherapy-naïve and relapsed cases, respectively. Survival data were also promising, with a median progression-free survival time and median survival time of 5.3 and 14.9 months and 4.7 and 10.2 months in the chemotherapy-naïve and relapsed cases, respectively. Even refractory-relapsed cases responded to the treatment favorably (27% ORR). The primary toxicity was myelosuppression with grades 3 or 4 neutropenia in 97% of the patients, which led to grades 3 or 4 febrile neutropenia in 41% of the patients and two toxic deaths. Conclusion: This phase II study showed the favorable efficacy and moderate safety profiles of a topotecan and amrubicin two-drug combination especially in relapsed patients with ED-SCLC. © 2011 Elsevier Ireland Ltd.

Objective: We examined the prognosis of patients with leptomeningeal metastasis (LM) from non-small cell lung cancer (NSCLC) and that stratified by epidermal growth factor receptor (EGFR) mutation status in LM patients receiving EGFR-tyrosine kinase inhibitors (TKIs). Methods: We retrospectively analyzed a series of 91 consecutive NSCLC patients with LM between 2001 and 2010. Results: Most of the LM patients had adenocarcinoma histology and a poor performance status (PS). The median survival time (MST) for all patients was 3.6 months. Adenocarcinoma and TKI treatment were associated with a better prognosis. Among the patients, 51 received EGFR-TKIs. Of these, the EGFR mutation status was assessed in 30 patients; 7 (23%) showed no mutation (group 1), 10 (33%) had a mutation in exon 21 (group 2), and 13 (43%) had deletions in exon 19 (group 3). Interestingly, PS was significantly improved in groups 2 and 3 but not in group 1. The MST in these subgroups was 1.4, 7.1, and 11.0 months in groups 1, 2, and 3, respectively (p< 0.001). The median time to progression or symptom deterioration was 0.9, 2.0, and 7.8 months for groups 1, 2, and 3, respectively (p< 0.001). A multivariate analysis showed that EGFR-mutant tumors were associated with a better prognosis in patients receiving EGFR-TKIs. Conclusions: The prognosis for patients with LM from NSCLC was still poor. Survival after the initiation of EGFR-TKI treatment differed according to the type of EGFR mutation, suggesting the potential benefit of TKIs for patients with EGFR mutations, even though they suffered from LM. © 2012 Elsevier Ireland Ltd.

Iron overload syndromes include a wide spectrum of genetic and acquired conditions. Recent studies suggest suppressed hepcidin synthesis in the liver to be the molecular basis of hemochromatosis. However, a liver with acquired iron overload synthesizes an adequate amount of hepcidin. Thus, hepcidin could function as a biochemical marker for differential diagnosis of iron overload syndromes. Methods We measured serum iron parameters and hepcidin- 25 levels followed by sequencing HFE, HJV, HAMP, TFR2, and SLC40A1 genes in 13 Japanese patients with iron overload syndromes. In addition, we performed direct measurement of serum hepcidin-25 levels using liquid chromatography-tandem mass spectrometry in 3 Japanese patients with aceruloplasminemia and 4 Italians with HFE hemochromatosis. Results One patient with HJV hemochromatosis, 2 with TFR2 hemochromatosis, and 3 with ferroportin disease were found among the 13 Japanese patients. The remaining 7 Japanese patients showed no evidence for genetic basis of iron overload syndrome. As far as the serum hepcidin-25 was concerned, seven patients with hemochromatosis and 3 with aceruloplasminemia showed markedly decreased serum hepcidin-25 levels. In contrast, 3 patients with ferroportin disease and 7 with secondary iron overload syndromes showed serum hepcidin levels parallel to their hyperferritinemia. Patients with iron overload syndromes were divided into 2 phenotypes presenting as low and high hepcidinemia. These were then associated with their genotypes. Conclusion Determining serum hepcidin-25 levels may aid differential diagnosis of iron overload syndromes prior to genetic analysis. © Springer 2010.
