| 1 | Endoscopic ultrasound-guided gallbladder drainage for acute cholecystitis: Long-term outcomes after removal of a self-expandable metal stent显示文摘AIM To assess the long-term outcomes of this procedure after removal of self-expandable metal stent(SEMS). The efficacy and safety of endoscopic ultrasoundguided gallbladder drainage(EUS-GBD) with SEMS were also assessed.METHODS Between January 2010 and April 2015, 12 patients with acute calculous cholecystitis, who were deemed unsuitable for cholecystectomy, underwent EUSGBD with a SEMS. EUS-GBD was performed under the guidance of EUS and fluoroscopy, by puncturing the gallbladder with a needle, inserting a guidewire, dilating the puncture hole, and placing a SEMS. TheSEMS was removed and/or replaced with a 7-Fr plastic pigtail stent after cholecystitis improved. The technical and clinical success rates, adverse event rate, and recurrence rate were all measured.RESULTS The rates of technical success, clinical success, and adverse events were 100%, 100%, and 0%, respectively. After cholecystitis improved, the SEMS was removed without replacement in eight patients, whereas it was replaced with a 7-Fr pigtail stent in four patients. Recurrence was seen in one patient(8.3%) who did not receive a replacement pigtail stent. The median follow-up period after EUS-GBD was 304 d(78-1492).CONCLUSION EUS-GBD with a SEMS is a possible alternative treatment for acute cholecystitis. Long-term outcomes after removal of the SEMS were excellent. Removal of the SEMS at 4-wk after SEMS placement and improvement of symptoms might avoid migration of the stent and recurrence of cholecystitis due to food impaction. | Ken Kamata Mamoru Takenaka Masayuki Kitano Shunsuke Omoto Takeshi Miyata Kosuke Minaga Kentaro Yamao Hajime Imai Toshiharu Sakurai Tomohiro Watanabe Naoshi Nishida Masatoshi Kudo | 2017 | World Journal of Gastroenterology2017,23,4: | 15 |
| 2 | Dietary polyphenols and colorectal cancer risk:The Fukuoka colorectal cancer study显示文摘AIM:To investigate the associations between dietary intake of polyphenols and colorectal cancer. METHODS:The study subjects were derived from the Fukuoka colorectal cancer study, a community-based case-control study. The study subjects were 816 cases of colorectal cancer and 815 community-based controls. The consumption of 148 food items was assessed by a computer-assisted interview. We used the consumption of 97 food items to estimate dietary intakes of total, tea and coffee polyphenols. The Phenol-Explorer database was used for 92 food items. Of the 5 foods which were not listed in the Phenol-Explorer Database, polyphenol contents of 3 foods (sweet potatoes, satoimo and daikon) were based on a Japanese study and 2 foods (soybeans and fried potatoes) were estimated by ORAC-based polyphenol contents in the United States Department of Agriculture Database. Odds ratios (OR) and 95%CI of colorectal cancer risk according to quintile categories of intake were obtained by using logistic regression models with adjustment for age, sex, residential area, parental history of colorectal cancer, smoking, alcohol consumption, body mass index 10 years before, type of job, leisure-time physical activity and dietary intakes of calcium and n-3 polyunsaturated fatty acids.RESULTS:There was no measurable difference in total or tea polyphenol intake between cases and controls, but intake of coffee polyphenols was lower in cases than in controls. The multivariate-adjusted OR of colorectal cancer according to quintile categories of coffee polyphenols (from the first to top quintile) were 1.00 (referent), 0.81 (95%CI:0.60-1.10), 0.65 (95%CI:0.47-0.89), 0.65 (95%CI:0.46-0.89) and 0.82 (95%CI:0.60-1.10), respectively (P trend = 0.07). Similar, but less pronounced, decreases in the OR were also noted for the third and fourth quintiles of total polyphenol intake. Tea polyphenols and non-coffee polyphenols showed no association with colorectal cancer risk. The sitespecific analysis, based on 463 colon cancer cases and 340 rectal cancer cases, showed an inverse association between coffee polyphenols and colon cancer. The multivariate-adjusted OR of colon cancer for the first to top quintiles of coffee polyphenols were 1.00 (referent), 0.92 (95%CI:0.64-1.31), 0.75 (95%CI:0.52-1.08), 0.69 (95%CI:0.47-1.01), and 0.68 (95%CI:0.46-1.00), respectively (P trend = 0.02). Distal colon cancer showed a more evident inverse association with coffee polyphenols than proximal colon cancer. The association between coffee polyphenols and rectal cancer risk was U -shaped, with significant decreases in the OR at the second to fourth quintile categories. There was also a tendency that the OR of colon and rectal cancer decreased in the intermediate categories of total polyphenols. The decrease in the OR in the intermediate categories of total polyphenols was most pronounced for distal colon cancer. Intake of tea polyphenols was not associated with either colon or rectal cancer. The associations of coffee consumption with colorectal, colon and rectal cancers were almost the same as observed for coffee polyphenols. The trend of the association between coffee consumption and colorectal cancer was statistically significant. CONCLUSION:The present findings suggest a decreased risk of colorectal cancer associated with coffee consumption. | Zhen-Jie Wang Keizo Ohnaka Makiko Morita Kengo Toyomura Suminori Kono Takashi Ueki Masao Tanaka Yoshihiro Kakeji Yoshihiko Maehara Takeshi Okamura Koji Ikejiri Kitaroh Futami Takafumi Maekawa Yohichi Yasunami Kenji Takenaka Hitoshi Ichimiya Reiji Terasaka | 2013 | World Journal of Gastroenterology2013,19,17: | 12 |
| 3 | Chromoendoscopy of gastric adenoma using an acetic acid indigocarmine mixture显示文摘AIM:To investigate the usefulness of chromoendoscopy,using an acetic acid indigocarmine mixture(AIM),for gastric adenoma diagnosed by forceps biopsy.METHODS:A total of 54 lesions in 45 patients diagnosed as gastric adenoma by forceps biopsy were prospectively enrolled in this study and treated by endoscopic submucosal dissection(ESD)between January 2011 and January 2012.AIM-chromoendoscopy(AIMCE)was performed followed by ESD.AIM solution was sprinkled and images were recorded every 30 s for 3min.Clinical characteristics such as tumor size(<2cm,≥2 cm),surface color in white light endoscopy(WLE)(whitish,normochromic or reddish),macroscopic appearance(flat or elevated,depressed),and reddish change in AIM-CE were selected as valuables.RESULTS:En bloc resection was achieved in all 54 cases,with curative resection of fifty two lesions(96.3%).Twenty three lesions(42.6%)were diagnosed as welldifferentiated adenocarcinoma and the remaining 31lesions(57.4%)were gastric adenoma.All adenocarcinoma lesions were well-differentiated tubular adenocarcinomas and were restricted within the mucosal layer.The sensitivity of reddish color change in AIM-CE is significantly higher than that in WLE(vs tumor size≥2 cm,P=0.016,vs normochromic or reddish surface color,P=0.046,vs depressed macroscopic type,P=0.0030).On the other hand,no significant differences were found in the specificity and accuracy.In univariate analysis,normochromic or reddish surface color in WLE(OR=3.7,95%CI:1.2-12,P=0.022)and reddish change in AIM-CE(OR=14,95%CI:3.8-70,P<0.001)were significantly related to diagnosis of early gastric cancer(EGC).In multivariate analysis,only reddish change in AIM-CE(OR=11,95%CI:2.3-66,P=0.0022)was a significant factor associated with diagnosis of EGC.CONCLUSION:AIM-CE may have potential for screening EGC in patients initially diagnosed as gastric adenoma by forceps biopsy. | Yoshiyasu Kono Ryuta Takenaka Yoshiro Kawahara Hiroyuki Okada Keisuke Hori Seiji Kawano Yasushi Yamasaki Koji Takemoto Takayoshi Miyake Shigeatsu Fujiki Kazuhide Yamamoto | 2014 | World Journal of Gastroenterology2014,20,17: | 12 |

| 5 | SH-wavefield simulation for a laterally heterogeneous whole-Earth model using the pseudospectral method显示文摘We present a scheme to simulate SH-wave propagation in a whole-Earth model with arbitrary lateral heterogeneities employing the Fourier pseudospectral method. Wave equations are defined in two-dimensional cylindrical coordinates and the model is taken through a great circle of the Earth. Spatial derivatives in the wave equations are calculated in the wavenumber domain by multiplication, and the transformation between spatial and wavenumber domains is performed via fast Fourier transformation. Because of the high accuracy and high speed of the Fourier pseudospectral method, the scheme enables us to calculate a short-wavelength global SH-wavefield with accurate waveforms and arrival times for models with heterogeneities that can be approximated as azimuthally symmetric. Comparing with two-dimensional simulation methods based on an axisymmetric model, implementing the seismic source in the present scheme is more convenient. We calculated the global SH-wavefield for the preliminary reference Earth model to identify the generation, reflection and refraction of various seismic phases propagating in the Earth. Applications to a heterogeneous global model with low-velocity perturbation above the core-mantle boundary were conducted to analyze the effect of lateral heterogeneity on global SH-wave propagation. | WANG YanBin TAKENAKA Hiroshi | 2011 | Science China Earth Sciences2011,54,12: | 7 |
| 6 | Prevention of aspiration of gastric contents during attempt in tracheal intubation in the semi-lateral and lateral positions显示文摘BACKGROUND:Pulmonary aspiration of gastric contents during tracheal intubation is a lifethreatening complication in emergency patients.Rapid sequence intubation is commonly performed to prevent aspiration but is not associated with low risk of intubation related complications.Although it has been considered that aspiration can be prevented in the lateral position,few studies have evaluated the ability to prevent aspiration.Moreover,this position is not always a favorable position for tracheal intubation.If aspiration can be prevented in a clinically relevant semi-lateral position,it may be advantageous.We assessed the ability to prevent aspiration in the lateral position and various degrees of the semi-lateral position using a vomiting-regurgitation manikin model.METHODS:A manikin's head was placed in the neutral,simple extension,or sniffing position.The amount of aspirated saline into the bronchi during simulated vomiting was measured at semilateral position angles of 0°to 90° in 10° increments.The difference in the vertical height between the mouth corner and the inferior border of the vocal cord was measured radiologically at each semilateral position in the three head-neck positions.RESULTS:Pulmonary aspiration was prevented at the ≥70°,≥80°,and 90° semi-lateral positions in the neutral,simple extension,and sniffing positions,respectively.The mouth was lower than the vocal cord in the semi-lateral position in which aspiration was prevented.CONCLUSION:The lateral or excessive semi-lateral position was necessary to protect the lung from aspiration in the head-neck positions commonly used for tracheal intubation.Prevention of aspiration was difficult within clinically relevant semi-lateral positions. | Ichiro Takenaka Kazuyoshi Aoyama | 2016 | World Journal of Emergency Medicine2016,7,4: | 7 |
| 7 | Tolerability of magnifying narrow band imaging endoscopy for esophageal cancer screening显示文摘AIM:To compare the tolerability of magnifying narrow band imaging endoscopy for esophageal cancer screening with that of lugol chromoendoscopy.METHODS:We prospectively enrolled and analyzed 51 patients who were at high risk for esophageal cancer.All patients were divided into two groups:a magnifying narrow band imaging group,and a lugol chromoendoscopy group,for comparison of adverse symptoms.Esophageal cancer screening was performed on withdrawal of the endoscope.The primary endpoint was a score on a visual analogue scale for heartburn after the examination.The secondary endpoints were scale scores for retrosternal pain and dyspnea after the examinations,change in vital signs,total procedure time,and esophageal observation time.RESULTS:The scores for heartburn and retrosternal pain in the magnifying narrow band imaging group were significantly better than those in the lugol chromoendoscopy group(P =0.004,0.024,respectively,ANOVA for repeated measures).The increase in heart rate after the procedure was significantly greater in the lugol chromoendoscopy group.There was no significant difference between the two groups with respect to othervital sign.The total procedure time and esophageal observation time in the magnifying narrow band imaging group were significantly shorter than those in the lugol chromoendoscopy group(450 ± 116 vs 565 ± 174,P =0.004,44 ± 26 vs 151 ± 72,P < 0.001,respectively).CONCLUSION:Magnifying narrow band imaging endoscopy reduced the adverse symptoms compared with lugol chromoendoscopy.Narrow band imaging endoscopy is useful and suitable for esophageal cancer screening periodically. | Yasushi Yamasaki Ryuta Takenaka Keisuke Hori Koji Takemoto Seiji Kawano Yoshiro Kawahara Hiroyuki Okada Shigeatsu Fujiki Kazuhide Yamamoto | 2015 | World Journal of Gastroenterology2015,21,9: | 5 |
| 8 | Effects of estradiol and progesterone on the proinflammatory cytokine production by mononuclear cells from patients with chronic hepatitis C显示文摘AIM:To investigate the effects of estradiol (E2) and progesterone on the unstimulated and oxidative stressstimulated production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-8, and macrophage chemotactic protein (MCP)-1 by peripheral blood mononuclear cells (PBMCs) from patients with chronic hepatitis C and healthy controls. METHODS:The PBMCs were separated from agematched 72 males and 71 females with and without chronic hepatitis C, who were divided into two groups based on a mean menopausal age of 50 years. Oxidative stress was induced by hydrogen peroxide in the cells incubated in serum-free media. Cytokines in the culture supernatant were measured by an enzyme-linked immunosorbent assay. RESULTS:The highest levels of the spontaneous production of TNF-α, IL-1β, IL-8, and MCP-1 by the unstimulated PBMCs were in the older male patients with chronic hepatitis C and the lowest levels were in the premenopausal female healthy controls. E2 inhibited the cytokine production by the unstimulated PBMCs from the older male and post-menopausal female patients, which was further stimulated by progesterone. The exposure to hydrogen peroxide in the PBMCs from the younger male and pre-menopausal female healthy subjects induced the production of cytokines. The change rates of the hydrogen peroxide-stimulated cytokine production were suppressed by E2 and enhanced by progesterone. CONCLUSION:These findings suggest that E2 may play a favorable role in the course of persistent liver injury by preventing the accumulation of monocytes-macrophages and by inhibiting proinflammatory cytokine production, whereas progesterone may counteract the favorable E2 effects. | Ying Yuan Ichiro Shimizu Mi Shen Eriko Aoyagi Hidetaka Takenaka Tatuzo Itagaki Mari Urata Katsutaka Sannomiya Nao Kohno Katsuyoshi Tamaki Masayuki Shono Tetsuji Takayama | 2008 | World Journal of Gastroenterology2008,14,14: | 5 |
| 9 | Risk factors for local recurrence and appropriate surveillance interval after endoscopic resection显示文摘BACKGROUND Risk factors for local recurrence after polypectomy, endoscopic mucosal resection(EMR), and endoscopic submucosal dissection(ESD) have not been identified.Additionally, the appropriate interval for endoscopic surveillance of colorectal tumors at high-risk of local recurrence has not been established.AIM To clarify the clinicopathological characteristics of recurrent lesions after endoscopic colorectal tumor resection and determine the appropriate interval.METHODS Three hundred and sixty patients(1412 colorectal tumors) who underwent polypectomy, EMR, or ESD and received endoscopic surveillance subsequently for more than one year to detect local recurrence were enrolled in this study. The clinicopathological factors associated with local recurrence were determined via univariate and multivariate analyses.RESULTS Local recurrence was observed in 31 of 360(8.6%) patients [31 of 1412(2.2%)lesions] after colorectal tumor resection. Piecemeal resection, tumor size of more than 2 cm, and the presence of villous components were associated with colorectal tumor recurrence after endoscopic resection. Of these three factors, the piecemeal resection procedure was identified as an independent risk factor for recurrence. Colorectal tumors resected into more than five pieces were associated with a high risk of recurrence since the average period from resection torecurrence in these cases was approximately 3 mo. The period to recurrence in cases resected into more than 5 pieces was much shorter than that in those resected into less than 4 pieces(3.8 ± 1.9 mo vs 7.9 ± 5.0 mo, P < 0.05).CONCLUSION Local recurrence of endoscopically treated colorectal tumors depends upon the outcome of first endoscopic procedure. Piecemeal resection was the only significant risk factor associated with local recurrence after endoscopic resection. | Yoriaki Komeda Tomohiro Watanabe Toshiharu Sakurai Masashi Kono Kazuki Okamoto Tomoyuki Nagai Mamoru Takenaka Satoru Hagiwara Shigenaga Matsui Naoshi Nishida Naoko Tsuji Hiroshi Kashida Masatoshi Kudo | 2019 | World Journal of Gastroenterology2019,25,12: | 4 |
| 10 | Radiation exposure during image-guided endoscopic procedures: The next quality indicator for endoscopic retrograde cholangiopancreatography显示文摘Endoscopic retrograde cholangiopancreatography(ERCP) is one of the most frequently used image-guided procedures in gastrointestinal endoscopy. Post-ERCP pancreatitis is an important concern, and prophylaxis, cannulation and other related technical procedures have been well documented by endoscopists. In addition, medical radiation exposure is of great concern in the general population because of its rapidly increasing frequency and its potential carcinogenic effects. International organizations and radiological societies have established diagnostic reference levels, which guide proper radiation use and serve as global standards for all procedures that use ionizing radiation. However, data on gastrointestinal fluoroscopic procedures are still lacking because the demand for these procedures has recently increased. In this review, we present the current status of quality indicators for ERCP and the methods for measuring radiation exposure in the clinical setting as the next quality indicator for ERCP. To reduce radiation exposure, knowledge of its adverse effects and the procedures for proper measurement and protection are essential. Additionally, further studies on the factors that affect radiation exposure, exposure management and diagnostic reference levels are necessary. Then, we can discuss how to manage medical radiation use inthese complex fluoroscopic procedures. This knowledge will help us to protect not only patients but also endoscopists and medical staff in the fluoroscopy unit. | Shiro Hayashi Mamoru Takenaka Makoto Hosono Tsutomu Nishida | 2018 | World Journal of Clinical Cases2018,6,16: | 4 |

| 12 | Central blood pressure and chronic kidney disease显示文摘In this review, we focused on the relationship between central blood pressure and chronic kidney diseases(CKD). Wave reflection is a major mechanism that determines central blood pressure in patients with CKD. Recent medical technology advances have enabled non-invasive central blood pressure measurements. Clinical trials have demonstrated that compared with brachial blood pressure, central blood pressure is a stronger risk factor for cardiovascular(CV) and renal diseases. CKD is characterized by a diminished renal autoregulatory ability, an augmented direct transmission of systemic blood pressure to glomeruli, and an increase in proteinuria. Any elevation in central blood pressure accelerates CKD progression. In the kidney, interstitial inflammation induces oxidative stress to handle proteinuria. Oxidative stress facilitates atherogenesis, increases arterial stiffness and central blood pressure, and worsens the CV prognosis in patients with CKD. A vicious cycle exists between CKD and central blood pressure. To stop this cycle, vasodilator antihypertensive drugs and statins can reduce central blood pressure and oxidative stress. Even in early-stage CKD, mineral and bone disorders(MBD) may develop. MBD promotes oxidative stress, arteriosclerosis, and elevated central blood pressure in patients with CKD. Early intervention or prevention seems necessary to maintain vascular health in patients with CKD. | Yoichi Ohno Yoshihiko Kanno Tsuneo Takenaka | 2016 | World Journal of Nephrology2016,5,1: | 3 |
| 13 | How the kidney hyperfiltrates in diabetes:From molecules to hemodynamics显示文摘In this review,we focused on two molecules,connexin and sodium-glucose cotransporter,which can link to diabetic hyperfiltration.In diabetic kidney,the activation of renin-angiotensin system occurs simultaneously with glomerular hyperfiltration.The latter largely dependson pathophysiological afferent arteriolar dilation in the presence of high angiotensin Ⅱ.As a mechanistic basis for the above,tubular hypothesis has been proposed for type 1 diabetic patients as well as experimental models.Although tubular hypothesis has not been well evaluated in type 2 diabetes,clinical observations support that tubular hypothesis is true also in type 2 diabetes.Recent results on tubular hypothesis along with connexin abnormality in type 2 diabetes were revisited.In addition,the importance of sodium-glucose cotransporter in diabetic hyperfiltration is discussed.The link between salt paradox and the activation of reninangiotensin system will be also reviewed. | Tsuneo Takenaka Tsutomu Inoue Yusuke Watanabe | 2015 | World Journal of Diabetes2015,6,4: | 3 |
| 14 | Global SH-wave propagation in a 2D whole Moon model using the parallel hybrid PSM/FDM method显示文摘We present numerical modeling of SH-wave propagation for the recently proposed whole Moon model and try to improve our understanding of lunar seismic wave propagation. We use a hybrid PSM/FDM method on staggered grids to solve the wave equations and implement the calculation on a parallel PC cluster to improve the computing efficiency. Features of global SH-wave propagation are firstly discussed for a 100-km shallow and900-km deep moonquakes, respectively. Effects of frequency range and lateral variation of crust thickness are then investigated with various models. Our synthetic waveforms are finally compared with observed Apollo data to show the features of wave propagation that were produced by our model and those not reproduced by our models. Our numerical modeling show that the low-velocity upper crust plays significant role in the development of reverberating wave trains. Increasing frequency enhances the strength and duration of the reverberations.Surface multiples dominate wavefields for shallow event.Core–mantle reflections can be clearly identified for deep event at low frequency. The layered whole Moon model and the low-velocity upper crust produce the reverberating wave trains following each phases consistent with observation. However, more realistic Moon model should be considered in order to explain the strong and slow decay scattering between various phases shown on observation data. | Xianghua Jiang Yanbin Wang Yanfang Qin Hiroshi Takenaka | 2015 | Earthquake Science2015,28,3: | 3 |
| 15 | Production and Accumulation of Xylooligosaccharides with Long Chains by Growing Culture and Xylanase of a Mutant Strain of Bacillus pumilus X-6-19显示文摘Bacillus pumilus X-6-9 isolated from soil and subsequently identified, produced xylooligosaccharides with long chains from xylan and accumulated them in the culture. By improving the culture conditions and mutating the bacterium, a 3.2-fold increase in the production of the xylooligosaccharides was established, when compared to the original culture conditions of B. pumilus X-6-19. The addition of D-glucose to the culture of the mutant strain U-3 of B. pumilus X-6-9 repressed the synthesis of β-xylosidase, but not xylanase. Thus, it was revealed that strain U-3 was a good organism for the production and accumulation of xylooligosaccharides with long chains from xylan by a microbial culture. Xylanase produced by strain U-3 was purified to homogeneity and characterized. The hydrolyzates generated by the purified xylanase contained xylobiose, xylotriose, xylotetraose, and xylopentaose, but not xylose. | Qingzhu Yuan Tsuyoshi Adachi Shinji Takenaka Shuichiro Murakami Machiko Tanaka Kenji Aoki | 2008 | 生物工程学报2008,24,7: | 3 |
| 16 | Management of gastric mucosa-associated lymphoid tissue lymphoma in patients with extra copies of the MALT1 gene显示文摘AIM To identify the clinical features of gastric mucosaassociated lymphoid tissue(MALT) lymphoma with extra copies of MALT1.METHODS This is a multi-centered,retrospective study. We reviewed 146 patients with MALT lymphoma in the stomach who underwent fluorescence in situ hybridization analysis for t(11;18) translocation. Patients were subdivided into patients without t(11;18) translocation or extra copies of MALT1(Group A,n = 88),patients with t(11;18) translocation(Group B,n = 27),and patients with extra copies of MALT1(Group C,n = 31). The clinical background,treatment,and outcomes of each group were investigated.RESULTS Groups A and C showed slight female predominance,whereas Group B showed slight male predominance. Mean ages and clinical stages at lymphoma diagnosis were not different between groups. Complete response was obtained in 61 patients in Group A(69.3%),22 in Group B(81.5%),and 21 in Group C(67.7%). Helicobacter pylori(H. pylori) eradication alone resulted in complete remission in 44 patients in Group A and 13 in Group C. In Group B,14 patients underwent radiotherapy alone,which resulted in lymphoma disappearance. Although the difference was not statistically significant,event-free survival in Group C tended to be inferior to that in Group A(P = 0.10).CONCLUSION Patients with t(11;18) translocation should be treated differently from others. Patients with extra copies of MALT1 could be initially treated with H. pylori eradication,similar to patients without t(11;18) translocation or extra copies of MALT1. | Masaya Iwamuro Ryuta Takenaka Masahiro Nakagawa Yuki Moritou Shunsuke Saito Shinichiro Hori Tomoki Inaba Yoshinari Kawai Tatsuya Toyokawa Takehiro Tanaka Tadashi Yoshino Hiroyuki Okada | 2017 | World Journal of Gastroenterology2017,23,33: | 3 |

| 18 | Randomized study of lafutidine vs lansoprazole in patients with mild gastroesophageal reflux disease显示文摘AIM: To compare the clinical efficacy of the secondgeneration H2 RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease(GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis(according to the Los Angeles classification) were randomized to receive lafutidine(10 mg, twice daily) or lansoprazole(30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale(GSRS), and the satisfaction score.RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment(P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group(P = 0.0068 and P = 0.0048, respectively).CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. | Ryuta Takenaka Hiroyuki Okada Seiji Kawano Yoshinori Komazawa Fumiya Yoshinaga Shinji Nagata Masafumi Inoue Hirohisa Komatsu Seiji Onogawa Yoshinori Kushiyama Shinichi Mukai Hiroko Todo Hideharu Okanobu Noriaki Manabe Shinji Tanaka Ken Haruma Yoshikazu Kinoshita | 2016 | World Journal of Gastroenterology2016,22,23: | 2 |
