RESUMEN

The present study investigated the prevalence of Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, M. hominis, and Ureaplasma spp. (biovars 1 and 2) in Japanese HIV-positive men who have sex with men (MSM). One-hundred-and-six Japanese HIV-infected MSM patients were enrolled. Anal and urine samples were collected and DNA testing for each microorganism was performed. Questionnaires regarding lifestyle habits and sexual behavior were administered. The prevalence of N. gonorrhoeae, C. trachomatis, M. genitalium, M. hominis, and Ureaplasma spp. in the anus was 5.6%, 8.9%, 4.4%, 5.6%, and 8.9%, respectively. A history of genital warts was an independent risk factor for detection of Mycoplasma spp. and Ureaplasma spp. The prevalence of these microorganisms in the anus of asymptomatic Japanese HIV-positive MSM was relatively high in agreement with previous reports from other countries.

RESUMEN

LESSONS LEARNED: In terms of efficacy and safety, good results were obtained with S-1 and paclitaxel (PTX) combination therapy.The findings suggest that S-1 and PTX combination therapy is a feasible treatment option in patients with previously treated non-small cell lung cancer. BACKGROUND: Although monotherapy with cytotoxic agents, including docetaxel and pemetrexed, is recommended for patients with previously treated advanced non-small cell lung cancer (NSCLC), its outcomes are unsatisfactory. S-1 is an oral fluoropyrimidine agent that consists of tegafur, 5- chloro-2, 4-dihydroxypyridine, and potassium oxonate. S-1 is approved for patients with gastric cancer in 7 Asian countries and 15 European countries. It is also approved for patients with eight type of cancers, including NSCLC, in Japan. We evaluated the efficacy and toxicity of S-1 and paclitaxel (PTX) combination therapy in patients with previously treated NSCLC. METHODS: Oral S-1 was administered thrice weekly on days 1-14 at 80, 100, and 120 mg/day in patients with body surface areas of <1.25, 1.25-1.5, and >1.5 m2, respectively. PTX was administered at 80 mg/m2 on days 1 and 8. Primary endpoint was response rate, and secondary endpoints were progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Forty patients were enrolled, with response and disease control rates of 27.5% and 75.0%, respectively (Fig. 1). Median PFS and OS were 6.5 and 20.7 months, respectively. Grade 3/4 anemia and thrombocytopenia were seen in five (12%) and one (2%) patients, respectively. Febrile neutropenia occurred in three patients (7%). Common grade 3/4 nonhematological toxicities were stomatitis (5% of patients), diarrhea (7% of patients), and interstitial lung disease (one patient). No treatment-related deaths were observed. CONCLUSION: This S-1 and PTX cotherapy dose and schedule showed satisfactory efficacy, with mild toxicities, in patients with previously treated advanced NSCLC.

RESUMEN

LESSONS LEARNED: Coadministration of S-1 and paclitaxel in elderly patients with advanced non-small cell lung cancer showed favorable efficacy.Coadministration of S-1 and paclitaxel in elderly patients with advanced non-small lung cancer showed tolerable toxicity. BACKGROUND: Although monotherapy with cytotoxic agents including docetaxel or vinorelbine are recommended for elderly patients with advanced non-small cell lung cancer (NSCLC), the outcome is not satisfactory. We evaluated the efficacy and safety of S-1 and paclitaxel (PTX) as a first-line cotreatment in elderly patients with advanced NSCLC. METHODS: Oral S-1 was administered on days 1-14 every 3 weeks at 80, 100, and 120 mg per day for patients with body surface area < 1.25 m2, 1.25-1.5 m2, and > 1.5 m2, respectively. PTX was administered at 80 mg/m2 on days 1 and 8. The primary endpoint was response rate, and secondary endpoints were progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Seventeen patients were enrolled with response and disease control rates of 47.1% and 88.2%, respectively. Median PFS and OS were 5.6 and 35.0 months, respectively. Hematological grade 3 or 4 toxicities included leukopenia (55.8%), neutropenia (52.9%), febrile neutropenia (11.8%), and anemia (11.8%). Nonhematological grade 3 toxicities included stomatitis (23.5%), diarrhea (5.9%), and interstitial lung disease (5.9%), and grade 5 toxicities included interstitial lung disease (5.9%). CONCLUSION: This S-1 and PTX cotherapy dose and schedule showed satisfactory efficacy with mild toxicities in elderly patients with advanced NSCLC.

RESUMEN

This phase I study was aimed at determining the maximum tolerated dose (MTD) and recommended dose (RD) for oral S-1 plus paclitaxel combination therapy in elderly patients with non-small cell lung cancer (NSCLC). Chemotherapy-naïve patients (age, >70 years) with stage III/IV NSCLC were treated with paclitaxel intravenously at four dose levels (DLs), 60, 70, 80, and 90 mg/m2, on day 1 and 8, and with S-1 (80 mg/m2) orally on days 1-14 every 3 weeks. MTD was defined as the dose at which two of the initial three patients experienced dose-limiting toxicities (DLTs). Three patients were added when the initial three patients experienced DLTs. The dose administered in three of the six patients with DLTs met the definition of MTD. The RD was defined as a dose 1 DL below the MTD. Fifteen patients including six on DL 1 and three each on DLs 2, 3, and 4 were enrolled. One patient experienced a DLT (febrile neutropenia) at DL 1. The remaining DLTs were noted at DL 4 (in one patient each): febrile neutropenia, grade (G) 3 skin rash, G3 diarrhea, G3 stomatitis, and G3 international normalized ratio (INR) elevation. The MTD of paclitaxel was 90 mg/m2. The RD for both S-1 and paclitaxel was 80 mg/m2 (DL 3). The response rate was 45.5% (8 of 15 patients achieved a partial response). In conclusion, the RD of both S-1 and paclitaxel was 80 mg/m2 in the combination therapy for chemotherapy-naïve patients with advanced NSCLC.

RESUMEN

BACKGROUND: The present study investigated human papillomavirus (HPV) prevalence in anal and urine samples, and evaluated cytological findings among human immunodeficiency virus (HIV)-infected Japanese men who have sex with men (MSM). METHODS: A total of 148 patients were enrolled. Anal and urine samples were collected from each participant, and a HPV-DNA test and genotyping were performed using flow-through hybridization. In addition, anal cytology was evaluated based on Papanicolaou staining. Questionnaires regarding lifestyle habits and sexual behavior were obtained. RESULTS: The ß-globin gene was positive in 131 (88.5%) anal samples and 139 (94.0%) urine samples. Among the ß-globin-positive samples, the HPV prevalence in anal and urine samples was 80.9% and 30.9%, respectively. High-risk HPV (HR-HPV) was detected in 57.3% of anal samples and 20.9% of urine samples. Among 122 adequate cytological samples, anal cytological abnormalities were observed in 99 cases (81.1%). Anal cytological tests revealed that atypical squamous cells of an undetermined significance (ASCUS) were detected in 57 (46.7%) patients, followed by low-grade squamous intraepithelial lesions (SIL) in 35 (28.7%), high-grade SIL in five (4.1%), and atypical squamous cells cannot exclude high-grade SIL (ASC-H) in two (1.6%), respectively. The nadir counts of CD4-positive T-lymphocyte less than 200 µL and anal HR-HPV infection were independent risk factors for anal cytological atypia over ASC-H. CONCLUSIONS: The present study demonstrated high HPV prevalence in the anus and urine, and showed a high incidence of anal cytological atypia associated with HR-HPV infections among HIV-infected MSM patients.

RESUMEN

BACKGROUND/AIM: Carfilzomib, lenalidomide, and dexamethasone (KRD) therapy is widely used for patients with relapse/refractory multiple myeloma (RRMM). However, the response in patients who underwent assessment for measurable residual disease (MRD) has not been elucidated in a prospective study. We aimed to clarify the response rate and outcome of KRD therapy in patients in RRMM, including those with MRD. PATIENTS AND METHODS: Twenty-one consecutive RRMM patients treated with KRD at 4 Japanese Centers between September 2016 and October 2018 were enrolled and assessed for MRD in the bone marrow (cut-off: 1×10-5) using the EuroFlow-next-generation flow (NGF) method. RESULTS: The median number of therapy lines before KRD was 3 (range=1-6), and the median number of KRD cycles was 4 (range=1-22). As the best overall response post-KRD therapy, 52% (11/21) of patients achieved a MRD negative complete response, 71% (15/21) achieved stringent complete response/complete response, and 14% (3/21) achieved a very good partial response. MRD negativity was achieved in 12 of 16 (75%) and 14 of 21 (67%) patients during and after KRD treatment, respectively. The 2-year progression-free survival and overall survival from the start of KRD therapy were 100% and 100%, respectively, in MRD-positive cases and 88% and 100%, respectively, in MRD-negative cases (median follow-up=1.8 years). Grade 3/4 toxicities were reported in 15 patients (71%), with thrombocytopenia being the most frequent toxicity (6 patients, 29%). CONCLUSION: This is the first study that prospectively assessed MRD of patients with RRMM after KRD therapy. KRD treatment achieved a high MRD negativity rate and good outcomes with manageable toxicities.

RESUMEN

This study was conducted as a prospective, multicenter trial to evaluate the efficacy and safety of micafungin as an empirical therapy for suspected invasive fungal infections (IFIs), including febrile neutropenia (FN), and to evaluate the usefulness of ß-D: -glucan (BG) and Aspergillus galactomannan (GM) antigen in patients with hematologic diseases. A total of 121 patients were enrolled and assessed for safety, and 119 were examined for clinical efficacy. The main underlying diseases were acute myeloid leukemia (38.0%), acute lymphoblastic leukemia (18.2%), and malignant lymphoma (18.2%). The median initial daily dose and duration of micafungin treatment were 150 mg/day and 13 days, respectively. The overall response rate for suspected IFIs (n = 119), based on four composite endpoints, including baseline IFI, breakthrough IFIs (proven and probable), survival, and premature discontinuation, was 79.0%. In addition, the response rate for FN (n = 81), based on these four endpoints as well as defervescence during neutropenia, was 39.5%. Breakthrough IFIs (proven, probable, and possible) occurred in five patients during micafungin treatment. All of these patients were positive for either BG or GM before the breakthrough IFIs. The incidence of adverse events (AEs) associated with micafungin was 10.7% and most were mild. The majority of AEs were liver dysfunction. These results indicate the effectiveness and safety of micafungin as an empirical therapy for suspected IFIs, including FN, and the usefulness of monitoring both BG and GM to detect breakthrough IFIs.

RESUMEN

A 76-year-old man was admitted to our hospital because of increasing size of lung nodules, while he was under observation for silicosis at another hospital. As the result of bronchoscopic biopsy, it was confirmed that they were silicotic nodules. However, he was hospitalized again about one month later due to left spontaneous pneumothorax. The pneumothorax improved immediately by persistent drainage of the thoracic cavity, but he developed a fever on day 9, and ground-glass opacities in both lungs also became exacerbated in spite of our administration of antibiotics. In addition, the level of MPO-ANCA increased markedly and multiple 3-10mm sized purpurae was seen on the right thigh on day 29. Skin biopsy specimens revealed infiltration of histiocytes and lymphocytes around medium-sized vessels in lower dermis. We diagnosed microscopic polyangiitis, then treated with steroid and immunosuppressive therapy. Fever and radiological findings improved significantly from the day after initiation of steroid administration. The patient was discharged on day 92 because of the improvement of his respiratory condition. We report a case of microscopic polyangiitis with silicosis, which markedly improved by steroid and immunosuppressive therapy.

RESUMEN

OBJECTIVE: Cisplatin is widely used for the treatment of non-small-cell lung cancer. However, it can cause unpleasant side effects and also requires prolonged hydration. We conducted a Phase II study of weekly gemcitabine and split-dose cisplatin in patients with advanced non-small-cell lung cancer (NSCLC) in order to reduce toxicity and shorten the time taken by administration. Our aims were to determine the response rate, toxicity and survival time with this regimen in patients with Stage IIIB/IV disease. METHODS: Previously untreated patients with Stage IIIB/IV NSCLC were given gemcitabine (1000 mg/m(2)) and split-dose cisplatin (40 mg/m(2)) on days 1 and 8 at 3-week intervals for four cycles. Gemcitabine was administered over the course of 30 min, and cisplatin was over the course of 60 min on the same days on an outpatient basis. RESULTS: Forty-five patients were enrolled, and all of them were assessable for response and toxicity. None had a complete response and 17 had a partial response (37.8%), for an overall response rate of 37.8% (95% confidence interval, 25.1-52.4%). The survival rate was 56.5% at 1 year and 38.9% at 2 years, with a median survival time of 15.7 months. Leukopenia, neutropenia, anemia and thrombocytopenia were the most common toxic reactions, with Grade > or = 3 reactions occurring at rates of 35%, 51%, 31% and 13%, respectively. CONCLUSIONS: Weekly gemcitabine and split-dose cisplatin is active and well tolerated in patients with Stage IIIB/IV NSCLC, administered on an outpatient basis without requiring prolonged hydration or hospitalization.

RESUMEN

A 69 year-old man was admitted to our hospital with bloody sputum and abnormal shadows in his chest X-ray film and CT. According to the bronchoscopic examination, he was diagnosed as suffering from small cell lung cancer (SCLC). Aside from SCLC, erythroderma, lymphoadenopathy and abnormal lymphoid cells in his peripheral blood were recognized on admission. Considering possible disorder blood complications, we conducted examinations including a biopsy of the skin and superficial lymph nodes, which revealed the characteristics of Sézary syndrome. We provided local treatment for Sézary syndrome and did systemic chemotherapy with carboplatin and etoposide for SCLC. After four cycles of chemotherapy, the patient showed a partial response. We report a very rare case of SCLC with Sézary syndrome in which we were able to provide chemotherapy effectively and safely.

RESUMEN

Continuous positive airway pressure (CPAP) therapy of obstructive sleep apnea syndrome (OSAS) is widely accepted. Recently it is reported that central type apnea increases in some patients with OSAS with the application of CPAP, and this type of sleep-disordered breathing is called complex sleep apnea syndrome (comp. SAS). However, until now its concept, mechanism and therapy have not been fully established. We treated 2 cases of comp. SAS with CPAP therapy. When we performed a polysomnography (PSG) examination in case 1 one year later, the symptoms had diminished and the central apnea had decreased, indicating the effectiveness CPAP therapy in case 1. In case 2, the symptoms had not diminished one year later. We therefore performed Adaptive Servo-Ventilation (ASV) therapy, resulting in improvement of symptoms and decrease of the central apnea. CPAP is not always effective in comp. SAS, and ASV can be suitable in such cases.

RESUMEN

The Revised International Staging System (R-ISS) was developed for a more accurate risk stratification of patients with symptomatic multiple myeloma (MM). However, original and subsequent validation studies of the R-ISS included relatively younger patients, many of whom were treated without bortezomib. Hence, we investigated the real-world prognostic performance of the R-ISS in 400 patients with MM treated with novel agents in Japan, an aging society. The patients had a median age of 72 years, and 96.0% were treated with bortezomib. Patients in R-ISS stage II were significantly older and failed to show significantly longer overall survival (OS) compared to patients in R-ISS stages III (median age; 74 and 70 years, respectively; P = 0.001, and median OS; 63.4 vs. 54.7 months, respectively; P = 0.32). However, OS differed significantly among patients with all conventional ISS stages. ISS stage III patients recategorized to R-ISS stage III were significantly younger than those recategorized to R-ISS stage II and had a relatively longer OS. As a reason for these findings, patients with the high-risk cytogenetic abnormality t(4;14) were significantly younger and had an improved OS compared to others, which can be attributed to a young age and bortezomib therapy, as previously suggested. In conclusion, the R-ISS was less successful than the ISS in discriminating between stages II and III among bortezomib-treated patients with MM in an aging society, which might be attributable to the inclusion of t(4;14) in the R-ISS categorization strategy.

RESUMEN

We sought to determine the efficacy of a new, inexpensive, single-tube 8-color multiparameter flow cytometry (MFC) method (SRL-Flow), which is based on the EuroFlow next-generation flow (NGF) (tube 2 only), to assess minimal residual disease (MRD)-negative status. MRD-negative status is considered a treatment milestone in multiple myeloma (MM). We used 45 bone marrow samples from patients with MM, including 11 cases treated with anti-CD38 monoclonal antibody. The SRL-Flow sample preparation protocol was identical to that of EuroFlow-NGF. The antibody panel for SRL-Flow was as follows: CD138V450/CD27V500/CD38ME (multiepitope)FITC/CD56PE/CD45PerCP-Cy5.5/CD19PE-Cy7/cytoplasmic (Cy) immunoglobulin (Ig) κAPC/CyIgλAPC-H7. To identify abnormal plasma cells (aPCs) of patients with MM who received anti-CD38 monoclonal antibody, we used a panel of anti-CD45 and anti-CD138 antibodies (Abs) rather than a panel of anti-CD45 and anti-CD38 Abs. We comparatively analyzed the total nucleated cell numbers, total PC levels, and MRD levels between the SRL-Flow and EuroFlow-NGF. High correlations (r > 0.9) in total PC and MRD levels were noted among SRL-Flow, original EuroFlow-NGF (2 tubes), and EuroFlow-NGF (tube 2 only), suggesting that SRL-Flow is an inexpensive (< $200 USD/sample as of January of 2019) alternative to EuroFlow-NGF (< $350 USD/sample) for assessing MRD in MM.

RESUMEN

BACKGROUND/AIM: The purpose of this trial was to evaluate the feasibility and efficacy of alternating platinum-based doublet chemotherapy with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR-mutant non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy-naive patients with advanced NSCLC harboring an EGFR mutation were enrolled. All patients underwent induction chemotherapy by sequentially alternating pemetrexed/cisplatin/bevacizumab and EGFR-TKIs followed by maintenance therapy with pemetrexed/bevacizumab and EGFR-TKIs. The primary outcome was the completion rate of the induction therapy. RESULTS: Eighteen eligible patients were enrolled between May 2011 and March 2016. The completion rate of induction therapy was 72.2% (13/18). Unfortunately, one patient developed grade 4 acute renal injury, but no other serious complications concerning this protocol were observed. Furthermore, diarrhea, rashes, and hematological adverse effects were mild. CONCLUSION: The completion rate of induction therapy was promising. Alternating chemotherapy and EGFR-TKIs should be further investigated regarding feasibility and efficacy.

RESUMEN

BACKGROUND: Efavirenz (EFV) is metabolized primarily by cytochrome P450 2B6 (CYP2B6), and high plasma concentrations of the drug are associated with a G-->T polymorphism at position 516 (516G-->T) of CYP2B6 and frequent central nervous system (CNS)-related side effects. Here, we tested the feasibility of genotype-based dose reduction of EFV. METHODS: CYP2B6 genotypes were determined in 456 human immunodeficiency virus type 1 (HIV-1)-infected patients who were receiving EFV treatment or were scheduled to receive EFV-containing treatment. EFV dose was reduced in CYP2B6 516G-->T carriers who had high plasma EFV concentrations while receiving the standard dosage (600 mg). EFV-naive homozygous CYP2B6 516G-->T carriers were treated with low-dose EFV. In both groups, the dose was further reduced when plasma EFV concentration remained high. RESULTS: CYP2B6 516G-->T was identified in the *6 allele (found in 17.9% of our subjects) and a novel allele, *26 (found in 1.3% of our patients). All EFV-treated CYP2B6 *6/*6 and *6/*26 carriers had extremely high plasma EFV concentrations (>6000 ng/mL) while receiving the standard dosage. EFV dose was reduced to 400 mg for 11 patients and to 200 mg for 7 patients with persistently suppressed HIV-1 loads. EFV-containing treatment was initiated at 400 mg in 4 CYP2B6 *6/*6 carriers and one *6/*26 carrier. Two of them still had a high plasma EFV concentration while receiving that dose, and the dose was further reduced to 200 mg, with successful HIV-1 suppression. CNS-related symptoms improved with dose reduction in 10 of the 14 patients, although some had not been aware of the symptoms at initial dosage. CONCLUSIONS: Genotype-based EFV dose reduction is feasible in CYP2B6 *6/*6 and *6/*26 carriers, which can reduce EFV-associated CNS symptoms.

RESUMEN

The increasing prevalence of drug-resistant HIV transmission has become a critical epidemic in the world today. Studies in developed countries reported 8-27% of newly diagnosed HIV/AIDS patients are infected by drug-resistant strains. To determine the prevalence of drug-resistant HIV-1 among newly diagnosed cases in Japan, eight HIV/AIDS clinical centers, three public health laboratories and the National Institute of Infectious Diseases conducted a nationwide survey. Between January 2003 and December 2004, 575 newly diagnosed HIV/AIDS patients with both acute and chronic infections were enrolled in the study. Twenty-three cases, including three recently infected patients, were infected with HIV-1 having major drug-resistance mutations, including M41L, D67N, L100I, K103N, V106A, M184I, M184V, L210W, and revertant mutations at the 215 codon in reverse transcriptase and M46I in protease encoding regions. In this newly diagnosed population, we also clarified the prevalence of hepatitis virus coinfection, which was 8.8% for HBV and 4.3% for HCV. In conclusion, the drug-resistant transmission rate was 4.0% in Japan. Although this rate is significantly lower than that of other developed countries, this rate almost reaches the threshold at which baseline genotypic resistance testing would be cost-effective for all infected persons before initiating therapy.

RESUMEN

Highly active antiretroviral therapy (HAART) can suppress human immunodeficiency virus type 1 (HIV-1) replication and plasma HIV-1 to below detectable levels. However, HAART becomes ineffective when drug-resistant viruses emerge during HAART. Monitoring drug-resistance mutations in viruses is necessary for selecting new drugs or therapies effective at inhibiting such HIV-1 variants. Most laboratories in Japan perform the tests using in-house protocols. However, the quality of these tests has never been assessed. Our study assessing the accuracy and reliability of HIV-1 genotypic drug-resistance testing in 15 laboratories in Japan revealed that the quality was very high (97.3% accurate). The errors, though rare, were caused by human errors, poor electropherograms, and the use of inadequate primers. Here, we propose troubleshooting procedures to improve testing accuracy and reliability in Japan.

RESUMEN

We report a case of refractory peripheral T-cell lymphoma (PTCL) successfully treated with a combination of fludarabine and cyclophosphamide (FLU/CY). A 68-year-old man with concurrent PTCL and diffuse large B-cell lymphoma was treated effectively with 3-course CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) therapy, but PTCL relapse occurred and was resistant to ESHAP (etoposide, methylprednisolone, cytarabine, and cisplatin) therapy. FLU/CY therapy led to complete remission, which was maintained for almost 14 months after a single course. We concluded that a FLU/CY regimen may be useful for attaining long-term remission in patients with refractory relapsed PTCL and should therefore be considered a valuable treatment choice.

RESUMEN

OBJECTIVES: We conducted phase I and II studies of biweekly docetaxel and cisplatin with concurrent radiotherapy, followed by consolidation chemotherapy with the same drugs in patients with locally advanced, unresectable non-small-cell lung cancer (NSCLC). Our objectives were to define the maximum-tolerated dose and dose-limiting toxicity (DLT) in the phase I study, and to determine the response rate, toxicity, and survival rate at the recommended dose (RD) in the phase II study. METHODS: Patients with unresectable stage IIIA and IIIB NSCLC were studied. Six to eight cycles of docetaxel and cisplatin were administered at 2-week intervals. In the phase I study, patients received four dose levels: level 1, docetaxel/cisplatin=30/40 mg/m2; level 2, 35/40; level 3, 40/40; and level 4, 45/40. Radiotherapy was delivered at a rate of 2 Gy per fraction/day up to a total dose of 60 Gy over the course of 6 weeks, during the first three cycles of chemotherapy. RESULTS: DLT comprised neutropenia at level 4 in the phase I study (n=15), and level 3 was considered the RD. In the phase II study (n=46), two patients had a complete response (4.3%) and 34 had a partial response (73.9%), for an overall response rate of 78.2% [95% CI (66.3-90.2%)]. The survival rate was 69.1% at 1 year and 39.6% at 2 years, with a median survival time of 19.1 months. Leukopenia, neutropenia, anemia, and radiation esophagitis were the most common toxic reactions, with Grade > or = 3 reactions occurring at rates of 77, 70, 17, and 8%, respectively. CONCLUSION: Biweekly docetaxel and cisplatin with concurrent RT was active and well tolerated in patients with unresectable stage III NSCLC.
