Fingolimod (FTY720) is known to have a significant therapeutic effect in various autoimmune disease models. Here, we examined FTY720 in a model of rheumatoid arthritis, induced by immunizing DBA/1 mice with a peptide consisting of residues 325 through 339 of glucose-6-phosphate isomerase (GPI 325-339). The efficacy was evaluated in terms of macroscopic findings, inflammatory cell infiltration and autoantibody level. Prophylactic administration of FTY720 from the day of immunization significantly suppressed the development of paw swelling, but therapeutic administration of FTY720 from onset of symptoms on day 8-9 was less effective. Interestingly, however, combination treatment with FTY720 plus GPI325-339 for 5 d after onset of symptoms significantly reduced the severity of symptoms in all mice, and no relapse occurred after booster immunization. Taking into account the reported mechanism of action of FTY720, these results indicate that combination treatment with FTY720 plus pathogenic autoantigen might efficiently induce immune tolerance by sequestering circulating autoantigen-specific lymphocytes from blood and peripheral tissues to the secondary lymphoid tissues. Combination treatment with FTY720 plus pathogenic autoantigen may become a breakthrough treatment for remission-induction in patients with autoimmune diseases including rheumatoid arthritis. © 2013 The Pharmaceutical Society of Japan.

OBJECTIVE - We have already reported that A1C is elevated because of iron deficiency in late pregnancy among nondiabetic pregnant women. This report examined whether the same phenomenon is observed in pregnant women with diabetes. RESEARCH DESIGN AND METHODS - This longitudinal study was conducted in 17 pregnant women with diabetes (20-35 weeks of pregnancy). A1C, serum glycated albumin, erythrocyte indexes, and iron metabolism indexes were measured. RESULTS - A1C levels were significantly increased in late pregnancy, whereas serum glycated albumin showed no significant changes. Glycated albumin/A1C ratio, mean corpuscular hemoglobin, serum transferrin saturation, and serum ferritin were significantly decreased in late pregnancy. Serum transferrin saturation showed a significant positive correlation with glycated albumin/A1C ratio. CONCLUSIONS - A1C levels, but not serum glycated albumin levels, are elevated in late pregnancy because of iron deficiency in diabetic women. Serum glycated albumin may offer an adequate marker for glycemic control during pregnancy. © 2010 by the American Diabetes Association.

The identification of human CD34-negative (CD34 ) hematopoietic stem cells (HSCs) provides a new concept for the hierarchy in the human HSC compartment. This study investigated the long-term repopulating capacity and redistribution kinetics of human cord blood-derived CD34 severe combined immunodeficiency (SCID)-repopulating cells (SRCs) and compared them with those of CD34 CD38 and CD34 CD38 SRCs using the intra-bone marrow injection (IBMI) to clarify the characteristics of CD34 SRCs. On the basis of the limiting dilution analyses data, estimated numbers of CD34 CD38, CD34 CD38, and CD34 SRCs were transplanted to NOD/SCID mice by IBMI. The human cell repopulation at the site of injection and the other bones were serially investigated. Interestingly, CD34 CD38, CD34 CD38, and CD34 SRCs began to migrate to other bones 2 and 5 weeks after the transplantation, respectively. Accordingly, the initiation of migration seemed to differ between the CD34 and CD34 SRCs. In addition, CD34 CD38 SRCs only sustained a short-term repopulation. However, both CD34 CD38 and CD34 SRCs had longer-term repopulation capacity. Taken together, these findings showed that CD34 SRCs show different in vivo kinetics, thus suggesting that the identified CD34 SRCs are a distinct class of primitive HSCs in comparison to the CD34 CD38 and CD34 CD38 SRCs. © 2010 Macmillan Publishers Limited All rights reserved.

Background: In patients with hemolytic anemia (HA), glycated hemoglobin (HbA 1C) presents lower values in relation to glycemia because the lifespan of erythrocytes is shortened, whereas glycated albumin (GA) is not affected. In the present study, we examined the usefulness of GA as an indicator of glycemic control status in patients with HA. Methods: We enrolled 21 patients with HA. A total of 202 patients with type 2 diabetes mellitus (T2DM) without complications were used as controls. Results: We identified a significant correlation between GA and HbA 1C in the patients with HA. However, in a comparison between the patients with HA and those with T2DM, the regression line showed a leftward shift in the former group. There was a significant positive correlation between hemoglobin (Hb) and HbA 1C in the patients with HA (R=0.541, p=0.025), although there was no significant correlation between Hb and GA. There was an inverse correlation between Hb levels and GA/HbA 1C ratio (R=-0.710, p=0.001). The measured HbA 1C levels were lower than the HbA 1C levels estimated from mean plasma glucose levels, whereas the GA/3 levels were close to the estimated HbA 1C levels. Conclusions: GA is a useful indicator of glycemic control status in patients with HA. © 2010 Elsevier B.V.

Once a day of arbekacin (ABK) administrations based on a new object of peak concentration setting on 9-20 microg/mL were performed to 14 neonates. The gestational ages were 27.3 +/- 4.2 weeks. As to the preparing initial dosage, Therapeutic Drug Monitoring Program soft was used. Mean daily dose of 6.2 +/- 0.4 mg/kg bodyweight was administered every 24 to 48 h by 30 min intravenous infusion. Mean serum peak concentrations of ABK and those of trough concentrations were 15.2 +/- 4.3 microg/mL and 2.0 +/- 1.4 microg/mL respectively. The relationship between the measured values (y) and predicted values (x) showed the regression equation y = 0.969 + 0.931x (R2 = 0.769, n = 35), which suggested the usefulness of the dosage design. Overall clinical effectiveness was 78.9% (11/14). There were no obvious adverse effects including abnormal auto auditory brainstem responses and serum creatinine increase. Effectiveness rate and no adverse effects suggested that once a day of ABK therapy in neonate including extremely preterm infant was preferable regimen.

Purpose of review: We intend to update the data of various clinical features and management of sarcoidosis in the aged. Recent findings: Subclinical or inapparent systemic involvement of sarcoidosis was found at autopsy in elderly patients who died from sarcoidosis, complication of malignancy, or cerebrovascular accidents. Sarcoidosis in the aged presents with unusual intrathoracic and extrapulmonary clinical features. Occasionally, these features may masquerade as malignancy. Sarcoidosis may appear or reactivate in patients receiving treatment with tumor necrosis factor antagonists or antiviral treatment. In elderly patients, antitumour necrosis factor treatment is effective for refractory sarcoidosis, methylphenidate hydrochloride for fatigue, and bosentan for sarcoidosis-associated pulmonary hypertension. Inhaled prostacyclin has been found to be effective in some patients with pulmonary hypertension. Sarcoidosis and malignancy can coexist. Summary: Autopsy studies revealed that both apparent and subclinical or inapparent systemic involvement of sarcoidosis might exist in aged patients with sarcoidosis. Aged sarcoidosis patients often present with unusual clinical features of sarcoidosis. Occasionally, these features resemble malignancy. New treatment with tumor necrosis factor antagonists for intractable sarcoidosis, methylphenidate hydrochloride for fatigue, and bosentan for sarcoidosis-associated pulmonary hypertension may be effective in sarcoidosis in the aged. Sarcoidosis and malignancy may coexist. © 2010 Wolters Kluwer Health | Lippincott Williams and Wilkins.

The aim of this study was to assess the incidence and risk factors for recurrent spontaneous preterm birth (PTB) in Japan.A retrospective cohort study was conducted at five tertiary perinatal centers in Osaka, Japan from 2008 through 2012. Perinatal data were collected from medical records of women with a singleton gestation and a previous spontaneous PTB. Exclusion criteria were first-trimester spontaneous abortion, first antenatal visit beyond 14weeks of gestation, and previous PTB with medical indications, placenta previa, abruptio placenta, multiple pregnancy, fetal anomaly, and antepartum fetal demise. The associations between recurrent spontaneous PTB and perinatal factors were evaluated by logistic regression analysis.Of 547 women with a previous spontaneous PTB, 89 (16.3%) suffered a recurrent spontaneous PTB. The risk factors for recurrence included multiple previous spontaneous PTB (adjusted odds ratio [aOR]: 2.26; 95% confidence interval [CI]: 1.19-4.30; P=0.013), no previous term birth (aOR: 2.08; 95%CI: 1.24-3.49; P=0.005), and interpregnancy interval<12months (aOR: 2.13; 95%CI: 1.17-3.85; P=0.013).Approximately one in six women with a previous spontaneous PTB suffered a recurrent spontaneous PTB. Multiple previous spontaneous PTB, no previous term birth, and short interpregnancy interval were independent risk factors for recurrence.

To evaluate the effect of antenatal corticosteroids (ANS) on short- and long-term outcomes in small-for-gestational age (SGA) infants.A retrospective database analysis was performed. A total of 1,931 single infants (birth weight <1,500 g) born at a gestational age between 22 weeks and 33 weeks 6 days who were determined to be SGA registered in the Neonatal Research Network Database in Japan between 2003 and 2007 were evaluated for short-term outcome and long-term outcome.ANS was administered to a total of 719 infants (37%) in the short-term outcome evaluation group and 344 infants (36%) in the long-term outcome evaluation group. There were no significant differences between the ANS group and the no-ANS group for primary short-term outcome (adjusted odds ratio (OR) 0.73; 95% confidence interval (CI) 0.45-1.20; P-value 0.22) or primary long-term outcome (adjusted OR 0.69; 95% CI 0.40-1.17; P-value 0.17).Our results show that ANS does not affect short- or long-term outcome in SGA infants when the birth weight is less than 1500 g. This study strongly suggests that administration of ANS resulted in few benefits for preterm FGR fetuses.

To evaluate the effect of antenatal corticosteroids (AC) therapy on short- and long-term outcomes among very low birth weight preterm infants after histologic chorioamnionitis (HCA).We performed a retrospective analysis of 5240 single very low birth weight (VLBW) infants born at 22 + 0 and 33 + 6 weeks of gestation between 2003 and 2007, who registered to the Neonatal Research Network Japan. The effects of AC therapy on mortality, neurodevelopmental outcomes at 3 years of age and neonatal morbidities were analyzed in the groups with or without HCA using logistic regression analysis.In the study subjects, 840 were with HCA, 2734 were without HCA, and 1666 were excluded without data for HCA. AC therapy was significantly associated with decreasing mortality before 3 years of age; [0.52 (0.32-0.86)], [odds ratio (95 % confidence intervals]. There were no differences between the two groups regarding neurodevelopmental outcomes, including cerebral palsy [0.90 (0.41-1.99)], development quotient <70 [0.93 (0.48-1.81)], visual impairment [0.46 (0.04-5.18)], and severe hearing impairment [4.00 (0.30-53.4)] in the group with HCA as well as without HCA. Regarding neonatal morbidities, AC therapy was associated with a lower incidence of respiratory distress syndrome [0.67 (0.50-0.91)], sepsis [0.62 (0.41-0.94)], late-onset adrenal insufficiency [0.62 (0.39-0.98)] and an increased incidence of chronic lung disease [1.62 (1.18-2.24)] in the group with HCA. In the group without HCA, AC therapy was associated with decreasing respiratory distress syndrome [0.60 (0.43-0.84)] and increasing chronic lung disease [1.34 (1.11-1.62)].AC therapy is significantly associated with reduced mortality before 3 years of age in VLBW infants with HCA, but not with neurodevelopmental outcomes, which was same as the results found in infants without HCA. AC therapy is recommended for women with suspected chorioamnionitis, as well as those without chorioamnionitis.

Ureaplasma spp. cause several disorders, such as nongonococcal urethritis, miscarriage, and preterm delivery with lung infections in neonates, characterized by pathological chorioamnionitis in the placenta. Although reports on antibiotic resistance in Ureaplasma are on the rise, reports on quinolone-resistant Ureaplasma infections in Japan are limited. The purpose of this study was to determine susceptibilities to five quinolones of Ureaplasma urealyticum and Ureaplasma parvum isolated from perinatal samples in Japan and to characterize the quinolone resistance-determining regions in the gyrA, gyrB, parC, and parE genes. Out of 28 clinical Ureaplasma strains, we isolated 9 with high MICs of quinolones and found a single parC gene mutation, resulting in the change S83L. Among 158 samples, the ParC S83L mutation was found in 37 samples (23.4%), including 1 sample harboring a ParC S83L-GyrB P462S double mutant. Novel mutations of ureaplasmal ParC (S83W and S84P) were independently found in one of the samples. Homology modeling of the ParC S83W mutant suggested steric hindrance of the quinolone-binding pocket (QBP), and de novo prediction of peptide structures revealed that the ParC S84P may break/kink the formation of the 4 helix in the QBP. Further investigations are required to unravel the extent and mechanism of antibiotic resistance of Ureaplasma spp. in Japan.
