RESUMO
Detailed evaluations of body mass index (BMI) and stool form based on the Bristol Stool Form Scale (BSFS) in individuals with constipation, gastroesophageal reflux disease (GERD), and concomitant constipation and GERD have not been performed in Japan. This study was an internet survey conducted to examine the relationships between BMI and constipation, GERD, stool forms based on the BSFS, and education level. This internet-based survey recruited participants from general public survey panels. 10,000 individuals meeting the eligibility criteria were enrolled. Questions included demographics, medical data, and assessments based on validated measures for constipation and GERD. BMI was significantly lower in males with versus without constipation. BMI was significantly higher with GERD both males and females. Mean BMI increased from the BSFS-1/2 group through the BSFS-3/4/5 to the BSFS-6/7 groups in both sexes. BMI was highest in individuals with a maximum education level of junior high school and second highest in individuals completing high school. This is the first real-world survey that closely examines the relationship between BMI and stool forms of individuals in Japan. When the BMI increased, stool forms varied from hard to watery in Japanese people. BMI was related with education level in Japan. (Trial registration: UMIN000039688).
RESUMO
INTRODUCTION: Constipation is a common symptom that impairs the quality of life (QOL). This study aimed to investigate the relationship between bowel movement and gut microbiota and dietary intake. METHODS: To investigate correlations among bowel movement, food intake, and gut environment, 60 healthy Japanese participants were recruited. Bowel movement was assessed using the Bristol stool form scale (BSFS) and constipation scoring system (CSS). Dietary habit was assessed with a self-administered questionnaire wherein the food intake frequency was classified into 8 categories for 72 food/food groups. Gut microbiota was analyzed using terminal restriction fragment length polymorphism analysis. RESULTS: The constipation rate was significantly higher in females than in males. The QOL was significantly impaired in the constipated group. The fecal count of Bacteroides was decreased and that of Clostridium cluster IV was increased in participants with constipation. The BSFS score was negatively associated with the fecal count of Clostridium cluster XI and positively associated with the fecal count of Clostridium cluster XVIII and consumption of green tea. The total CSS score was positively associated with the fecal Prevotella count and negatively associated with fecal acetate levels and consumption of vegetables. Discriminant analysis estimated that constipation could be predicted correctly in 83% (p < 0.001) of the participants based on fecal microbiota and fecal short-chain fatty acids. DISCUSSION/CONCLUSION: Bowel movement was strongly affected by gut environment and food intake in Japanese participants. Improvement in dietary habits could promote bowel movement through the improvement of the environment in the gut, resulting in ameliorated QOL issues in healthy adults.

The role of enterobacterial flora in the onset and progression of inflammatory bowel diseases is a topic of considerable interest. Here, we assessed the association among enterobacterial flora, dietary factors, and ulcerative colitis (UC) progression. Forty-six patients with UC who were diagnosed as being in remission were enrolled. We collected each patient's stool sample one or two days before diagnostic colonoscopy. After colonoscopy, we observed the patients for one year and then retrospectively divided them into two groups: remission (n = 39) and relapse (n = 7) groups, depending on whether the relapse occurred during the follow-up period, and analyzed the relationship among patient characteristics, dietary factors, enterobacterial flora, and UC relapse. Overall, there were no significant differences in bacterial community populations between the remission and relapse groups, except that the order Lactobacillales was detected at a significantly higher rate in the relapse than in the remission group (100% vs 71.4%, p<0.05). Vitamin C intake was significantly higher in the remission than in the relapse group (p<0.05). Although there were no obvious differences in enterobacterial flora between the remission and relapse groups, there was a relationship among enterobacterial flora, diet, and UC progression. Given that the enterobacterial flora was only analyzed at the initiation of the study, we conclude that in future analyses, enterobacterial flora should be sampled at numerous time points to examine its role in UC progression. Further long-term longitudinal studies examining enterobacterial flora, dietary factors, and UC progression are also required.
RESUMO
OBJECTIVE: The purpose of this study was to compare intended and actual yearly genetic gains for milk production and conformation traits and to investigate the simple selection criterion practiced among milk production and conformation traits during the last two decades in Japan. Learning how to utilize the information on intended and actual genetic gains during the last two decades into the genomic era is vital. METHODS: Genetic superiority for each trait for four paths of selection (sires to breed bulls [SB], sires to breed cows [SC], dams to breed bulls [DB], and dams to breed cows [DC]) was estimated. Actual practiced simple selection criteria were investigated among milk production and conformation traits and relative emphasis on milk production and conformation traits was compared. RESULTS: Selection differentials in milk production traits were greater than those of conformation traits in all four paths of selection. Realized yearly genetic gain was less than that intended for milk production traits. Actual annual genetic gain for conformation traits was equivalent to or greater than intended. Retrospective selection weights of milk production and conformation traits were 0.73:0.27 and 0.56:0.44 for intended and realized genetic gains, respectively. CONCLUSION: Selection was aimed more toward increasing genetic gain in milk production than toward conformation traits over the past two decades in Japan. In contrast, actual annual genetic gain for conformation traits was equivalent to or greater than intended. Balanced selection between milk production and conformation traits tended to be favored during actual selection. Each of four paths of selection (SB, SC, DB, and DC) has played an individual and important role. With shortening generation interval in the genomic era, a young sire arises before the completion of sire's daughters' milk production records. How to integrate these four paths of selection in the genomic era is vital.
RESUMO
OBJECTIVE: Models for genomic selection assume that the reference population is an unselected population. However, in practice, genotyped individuals, such as progeny-tested bulls, are highly selected, and the reference population is created after preselection. In dairy cattle, the intensity of selection is higher in males than in females, suggesting that cows can be added to the reference population with less bias and loss of accuracy. The objective is to develop formulas applied to any genomic prediction studies or practice with preselected animals as reference population. METHODS: We developed formulas for calculating the reliability and bias of genomically enhanced breeding values (GEBV) in the reference population where individuals are preselected on estimated breeding values. Based on the formulas presented, deterministic simulation was conducted by varying heritability, preselection percentage, and the reference population size. RESULTS: The number of bulls equal to a cow regarding the reliability of GEBV was expressed through a simple formula for the reference population consisting of preselected animals. The bull population was vastly superior to the cow population regarding the reliability of GEBV for low-heritability traits. However, the superiority of reliability from the bull reference population over the cow population decreased as heritability increased. Bias was greater for bulls than cows. Bias and reduction in reliability of GEBV due to preselection was alleviated by expanding reference population. CONCLUSION: Cows are easier in expanding reference population size compared with bulls and alleviate bias and reduction in reliability of GEBV of bulls which are highly preselected than cows by expanding the cow reference population.
RESUMO
Few studies have investigated the host-microbe metabolic axis in people with type 2 diabetes mellitus (T2DM). This study aimed to determine and compare the nutrient intakes and metabolic markers and to elucidate the relationships among these factors in Japanese T2DM patients and control individuals. Fifty-nine Japanese T2DM patients and 59 matched healthy control individuals participated in this study. We examined the differences regarding the participants' dietary habits, microbiota, and fecal short-chain fatty acids, and analyzed the relationships between the gut microbiota and blood metabolic markers in the T2DM patients and the control subjects. The T2DM patients consumed more carbohydrates, and had lower fecal propionate and butyrate concentrations, larger fecal populations of Bifidobacterium spp. and bacteria of the order Lactobacillales, and smaller fecal Bacteroides spp. populations than the control individuals. In the T2DM patients, the level of Bifidobacterium spp. correlated negatively with the carbohydrate intake and the level of bacteria of the order Lactobacillales correlated negatively with the protein intake. T2DM patients have gut dysbiosis that may contribute to disease onset and influence its prognosis. Furthermore, homeostatic disturbances in the gut-related metabolism may underlie the pathogenesis of T2DM.
RESUMO
An 82-year-old man with abdominal pain was admitted to our hospital. Laboratory tests revealed the following:white blood cells, 14300/µl;serum hemoglobin level, 12.9g/dl;serum C-reactive protein level, 0.38mg/dl;and negative anti-Helicobacter pylori immunoglobulin G test. Abdominal computed tomography revealed a tumor in the appendix along with multiple swollen lymph nodes. Colonoscopy revealed a submucosal tumor (SMT) of approximately 30mm in diameter with central ulceration. However, a tumor tissue specimen could not be obtained for biopsy;thus, the tumor could not be diagnosed. In esophagogastroduodenoscopy, abnormalities or gastric mucosal atrophy was not observed. A rapid urease test yielded negative results. Hence, endoscopic ultrasound-guided fine needle aspiration for the SMT was recommended;however, the patient preferred to undergo a definitive surgery to establish exact diagnosis. Therefore, right hemicolectomy and lymph node dissection (D3) were performed. Histopathologically, the resected tumor specimen showed atypical lymphocytes. Additionally, immunohistochemical evaluation demonstrated positive staining of the tumor cells for CD20 and BCL2 and negative staining for CD34, CD4, CD10, and BCL6. The tumor was finally diagnosed as a stage II2 mucosa-associated lymphoid tissue lymphoma (Lugano classification). Postoperatively, the patient received chemotherapy with four cycles of rituximab based on his age and activities of daily living.

Although chronic constipation is highly prevalent, its definition remains unclear. Therefore, the prevalence varies depending on reports, and the understanding of actual situations is unclear. Hence, we performed an internet survey on constipation among the Japanese general population to study the background factors and actual situations. Preliminary study on the awareness of constipation was conducted among 10000 people in which 9523 of them was asked if they had constipation at the time of the survey. In this population, 51.5% realized that they had constipation. Multivariate analysis showed the significant association of constipation to age, sex, and past histories or complications of diabetes, hemorrhoids, and cerebrovascular diseases. In a main research composed of 3000 general Japanese population, approximately 30.9% of the subjects reported the use of laxatives to treat constipation, and 43.8% of them were found to use irritant laxatives. Moreover, 67.5% of the subjects purchased laxatives at a pharmacy. The frequency of bowel movement less than 3 times per week was manifested in 36.3% of the subjects, and more than once per week in 21.4%. The percentage of hard (Bristol Stool Form Scale [BSFS] Type 1-2), normal (BSFS Type 3-5), and diarrhea stools (BSFS Type 6-7) was 33.1%, 60.0%, and 6.9%, respectively. The quality of life (QOL) of the subjects with hard and diarrhea stools evaluated by SF-8 was significantly lower than that of those with normal stools. Furthermore, the actual monthly cost for the therapeutic drugs used for treating constipation was less than 1000 yen in 75% of the subjects. Analysis of the IBS-QOL-J indicated that the ≥5000 yen payable group had the lowest satisfaction of defecation among the study groups. At present, many Japanese patients with constipation have not been receiving enough treatment for constipation. Therefore, appropriate medication by physicians as well as instruction to patients is required.

OBJECTIVE: In practical breeding, selection is often performed by ignoring the accuracy of evaluations and applying economic weights directly to the selection index coefficients of genetically standardized traits. The denominator of the standardized component trait of estimated genetic evaluations in practical selection varies with its reliability. Whereas theoretical methods for calculating the selection index coefficients of genetically standardized traits account for this variation, practical selection ignores reliability and assumes that it is equal to unity for each trait. The purpose of this study was to clarify the effects of ignoring the accuracy of the standardized component trait in selection criteria on selection responses and economic weights in retrospect. METHODS: Theoretical methods were presented accounting for reliability of estimated genetic evaluations for the selection index composed of genetically standardized traits. RESULTS: Selection responses and economic weights in retrospect resulting from practical selection were greater than those resulting from theoretical selection accounting for reliability when the accuracy of the estimated breeding value (EBV) or genomically enhanced breeding value (GEBV) was lower than those of the other traits in the index, but the opposite occurred when the accuracy of the EBV or GEBV was greater than those of the other traits. This trend was more conspicuous for traits with low economic weights than for those with high weights. CONCLUSION: Failure of the practical index to account for reliability yielded economic weights in retrospect that differed from those obtained with the theoretical index. Our results indicated that practical indices that ignore reliability delay genetic improvement. Therefore, selection practices need to account for reliability, especially when the reliabilities of the traits included in the index vary widely.
RESUMO
The impairment of orofacial motor function during orthodontic treatment needs to be addressed, because most orthodontic patients experience pain and motor excitability would be affected by pain. In the present study, the temporal alteration of the jaw-opening reflex excitability was investigated to determine if orthodontic treatment affects orofacial motor function. The excitability of jaw-opening reflex evoked by electrical stimulation on the gingiva and recorded bilaterally in the anterior digastric muscles was evaluated at 1 (D1), 3 (D3), and 7 days (D7) after orthodontic force application to the teeth of right side; morphological features (e.g., osteoclast genesis and tooth movement) were also evaluated. To clarify the underlying mechanism of orthodontic treatment-induced alteration of orofacial motor excitability, analgesics were administrated for 1 day. At D1 and D3, orthodontic treatment significantly decreased the threshold for inducing the jaw-opening reflex but significantly increased the threshold at D7. Other parameters of the jaw-opening reflex were also evaluated (e.g., latency, duration and area under the curve of anterior digastric muscles activity), and only the latency of the D1 group was significantly different from that of the other groups. Temporal alteration of the jaw-opening reflex excitability was significantly correlated with changes in morphological features. Aspirin (300 mg·kg-1·day-1) significantly increased the threshold for inducing the jaw-opening reflex, whereas a lower dose (75-150 mg·kg-1·day-1) of aspirin or acetaminophen (300 mg·kg-1·day-1) failed to alter the jaw-opening reflex excitability. These results suggest that an increase of the jaw-opening reflex excitability can be induced acutely by orthodontic treatment, possibly through the cyclooxygenase activation.NEW & NOTEWORTHY It is well known that motor function is affected by pain, but the effect of orthodontic treatment-related pain on the trigeminal motor excitability has not been fully understood. We found that, during orthodontic treatment, trigeminal motor excitability is acutely increased and then decreased in a week. Because alteration of trigeminal motor function can be evaluated quantitatively by jaw-opening reflex excitability, the present animal model may be useful to search for alternative approaches to attenuate orthodontic pain.

BACKGROUND/AIMS: We evaluated the role of serum-derived hyaluronan-associated protein (SHAP) in inflammatory bowel disease (IBD) pathogenesis and its potential as a novel IBD biomarker. METHODS: We studied the SHAP expression in a mouse model of colitis and in human intestinal samples of IBD and compared serum concentrations with normal controls. RESULTS: SHAP was expressed in the connective tissue derived from inflamed regions of the intestine. In mice, serum levels of SHAP-hyaluronic acid (SHAP-HA) were positively correlated with the histological damage of the colon (r = 0.566, p < 0.001). Serum concentration of SHAP-HA complex was significantly higher in patients with active ulcerative colitis than in those in remission, and this value was positively correlated with the erythrocyte sedimentation rate, serum level of tumor necrosis factor (TNF)-α, and endoscopic damage (r = 0.568, p < 0.001; r = 0.521, p < 0.001, and r = 0.641, p < 0.001). In patients with Crohn's disease, the serum SHAP-HA level correlated only with TNF-α (r = 0.630, p = 0.002). CONCLUSION: SHAP is a novel IBD biomarker that is related to disease activity in certain types of colitis, and it may affect disease pathogenesis. Future studies are needed to evaluate the therapeutic potential of this complex.

BACKGROUND/AIMS: Evidence suggests that intestinal microbiota, along with factors such as diet and host genetics, contributes to obesity, metabolic dysfunction and diabetes. Therefore, we examined the relationship between gut microbiota, blood metabolic markers, dietary habits and fecal short-chain fatty acids (SCFAs) in patients with type 2 diabetes mellitus (T2DM). METHODS: Dietary habits, blood and fecal samples from 59 T2DM patients were recruited, and the association of intestinal microbiota with metabolic markers and dietary habits was analyzed. RESULTS: Total energy intake was 1,692 ± 380 kcal/day. Carbohydrate, fat and protein intakes were 57.5 ± 5.2, 23.2 ± 5.3 and 13.2 ± 2.2%, respectively. Dietary habits - high carbohydrate, fat, and protein intake - were associated with increased counts of Clostridium clusters IV and XI and decreased counts of Bifidobacterium spp., order Lactobacillales and Clostridium cluster IV. Protein intake was negatively correlated with fecal acetate and total SCFAs. Total SCFAs, propionate and acetate were negatively correlated with blood insulin levels and the homeostasis model of insulin resistance. CONCLUSION: Diets low in protein and carbohydrates favor a healthy gut microbiome and improve glucose tolerance in T2DM patients, although further elucidation of the role of the gut microbiome could lead to better therapies and prophylaxes.

Current concepts of basal ganglia function have evolved from the essentially motoric, to include a range of extramotoric functions that involve not only dopaminergic but also cholinergic, γ-aminobutyric acid (GABA)ergic and glutamatergic mechanisms. We consider these mechanisms and their efferent systems, including spiralling, feed-forward striato-nigro-striatal circuitry, involving the dorsal and ventral striatum and the nucleus accumbens (NAc) core and shell. These processes are illustrated using three behavioural models: turning-pivoting, orofacial movements in rats and orofacial movements in genetically modified mice. Turning-pivoting indicates that dopamine-dependent behaviour elicited from the NAc shell is funnelled through the NAc-nigro-striato-nigro-pedunculopontine pathway, whereas acetylcholine-dependent behaviour elicited from the NAc shell is funnelled through the NAc-ventral pallidum-mediodorsal thalamus pathway. Cooperative/synergistic interactions between striatal D1-like and D2-like dopamine receptors regulate individual topographies of orofacial movements that are funnelled through striatal projection pathways and involve interactions with GABAergic and glutamatergic receptor subtypes. This application of concerted behavioural, neurochemical and neurophysiological techniques implicates a network that is yet broader and interacts with other neurotransmitters and neuropeptides within subcortical, cortical and brainstem regions to 'sculpt' aspects of behaviour into its topographical collective.

AIM: We aimed to elucidate the relationship between the contrast enhancement effect of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) on magnetic resonance imaging (MRI) of hepatocellular carcinomas (HCC) and the expressions of hepatocyte transporters (i.e. organic anion-transporting polypeptide [OATP]1B3, multidrug-resistant protein [MRP]2 and MRP3) and to clarify the characteristics of HCC with an MRI high-contrast enhancement effect. METHODS: We retrospectively examined the relationship between the relative enhancement ratio (RER) of HCC, absolute and relative immunohistochemical staining scores of hepatocyte transporters, and histological differentiation of 22 HCC from 21 patients who had undergone preoperative Gd-EOB-DTPA-enhanced MRI. RESULTS: RER had a significant correlation with OATP1B3 expression according to the absolute and relative scores (P = 0.016 vs 0.0006). The RER of HCC with high OATP1B3 and MRP2 expression levels was higher than that of HCC with low OATP1B3 or MRP2 expression levels (P = 0.0003). The RER of HCC with higher OATP1B3 rates was greater than that of HCC with lower OATP1B3 rates (P = 0.0005). HCC histological differentiation showed a significant correlation with OATP1B3 expression and RER (P = 0.023 vs 0.0095). CONCLUSION: We found that coexpression of OATP1B3 and MRP2 influenced the high contrast enhancement of HCC on MRI.
RESUMO
This in vivo mouse model study was conducted to investigate the temporal alteration of the function of CD36 in salivary secretion. CD36 was highly expressed in the parotid gland of BALB/c mice. No significant variations were shown in the CD36 levels in the 8-, 48-, and 72-week-old animals. However, pilocarpine-induced salivary secretion was reduced in an age-dependent manner, showing a significantly low level at the age of 72 weeks. Pilocarpine-induced salivary secretion was significantly reduced by pretreatment with a CD36 inhibitor at 8 and 48 weeks, but not at 72 weeks. In senescence-accelerated mice (SAM), the pilocarpine-induced salivary secretion was significantly reduced at the age of 56 weeks, and a significantly lower amount of CD36 was demonstrated in the parotid gland, compared with the control. These results suggest that the involvement of parotid CD36 in mouse salivary secretion is altered with age.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms, and it is associated with several prodromal non-motor symptoms, including an impaired sense of smell, taste and touch. We previously reported that bitter taste impairments occur independently of olfactory impairments in an early-stage PD animal model using short-term intranasal rotenone-treated mice. Cool temperatures also affect bitter taste perception, but it remains unclear whether or not bitter taste impairments result from an altered sensitivity for intraoral cool stimuli. We examined disturbances in the intraoral menthol sensitivity, such as coolness at low concentrations of menthol, using a brief-access test. Once a day, one solution from the 7-concentration series of (-)-menthol (0-2.3 mM) or the bitter taste quinine-HCl (0.3 mM) was randomly presented 20 times for 10 s to water-deprived mice before and 1 week after rotenone treatment. The total number of licks within 20 times was significantly decreased with the presentation of 2.3 mM menthol and quinine-HCl, compared to distilled water in untreated mice, but not in rotenone-treated mice. The correlation between the licks for quinine-HCl and that for menthol was increased after rotenone treatment. In contrast, the 2-bottle choice test for 48 h clarified that menthol sensitivity was increased after rotenone treatment. Furthermore, a thermal place preference test revealed that seeking behavior toward a cold-floored room was increased in the rotenone-treated mice despite the unchanged plantar cutaneous cold sensitivity. These results suggest that taste impairments in this model mice are at least partly due to intraoral somatosensory impairments, accompanied by peripheral/central malfunction.
RESUMO
BACKGROUND AND AIMS: Acute lower gastrointestinal bleeding (ALGIB) increase with age and the administration of antiplatelet drugs. Colonic diverticular bleeding (CDB) is the most common cause of ALGIB, and endoscopic hemostasis is an effective treatment for massive CDB. But in patients without extravasation on contrast-enhanced computed tomography (CECT), the efficacy of urgent colonoscopy (UCS) is controversial from the point of the clinical course, including rebleeding rate. We aimed to establish a potential strategy including UCS for CDB patients without extravasation on CECT. PATIENTS AND METHODS: Patients from two centers treated for CDB without extravasation on CECT between July 2014 and July 2019 were retrospectively identified (n = 282). Seventy-four underwent UCS, and 208 received conservative management. We conducted two analyses. The first analysis investigates the risk factors of rebleeding rate within 5 days after administration (very early rebleeding), and no UCS (NUCS) was not the independent factor of the very early rebleeding. The second analysis is whether UCS positively influenced the clinical course after hospitalization. RESULTS: The prevalence of very early rebleeding and early rebleeding (6-30 days from admission), patients requiring blood transfusion within 0-5 days and 6-30 days post-admission, and duration of hospitalization were examined as clinical course factors between UCS and NUCS group. There was no significant difference between the UCS and non-UCS groups in the clinical course factors. UCS for the CDB patients without extravasation was not improved rebleeding rate and clinical course. CONCLUSIONS: UCS is not necessary in case ofCDB patient without extravasation on CECT.

A 46-year-old man, receiving continuous steroid therapy for refractory ulcerative colitis with an insufficient response to anti-tumor necrosis factor-α therapy, presented with left buttock pain. He was diagnosed with steroidal left femoral head necrosis, and total proctocolectomy with permanent ileostomy was performed. At 6 months postoperatively, the patient developed general fatigue, abdominal pain, and severe ileostomy diarrhea. Computed tomography revealed continuous intestinal edema from the descending duodenal leg to the upper jejunum. Gastrointestinal endoscopy revealed deep ulcers, coarse mucosa, and duodenal erosion. Based on clinical progress, findings, and pathology, the patient was diagnosed with ulcerative colitis-related postoperative enteritis. Although 5-aminosalicylic acid treatment was initiated, his symptoms persisted, bloody diarrhea from colostomy was observed. Subsequently, granulocyte and monocyte apheresis treatment was added. Symptoms and endoscopic findings improved with granulocyte and monocyte apheresis. Azathioprine was introduced as maintenance therapy, and no sign of recurrence was observed. Although ulcerative colitis-related postoperative enteritis has no definitive treatment, granulocyte and monocyte apheresis may be considered for initial treatment.

A 54-year-old man was referred to our hospital because of a suspected esophageal submucosal tumor on upper gastrointestinal radiography. Contrast-enhanced computed tomography showed a 52 mm homogeneous mass attached to the lower thoracic esophagus. Esophagogastroduodenoscopy revealed a 50 mm submucosal tumor in the lower esophagus, and endoscopic ultrasonography (EUS) showed a continuous hypoechoic lesion in the esophageal muscularis propria. Contrast-enhanced harmonic EUS revealed a non-echogenic area. T1 and T2 magnetic resonance imaging revealed a high-signal lesion. Based on imaging studies, an esophageal duplication cyst was diagnosed. Although asymptomatic, the patient underwent video-assisted thoracic surgery because of the possibility of rupture and the appearance of symptoms due to a future infection or enlargement, although this was not noted before. In our case, the esophageal duplication cyst appeared as a hypoechoic mass, requiring differentiation from submucosal tumor other than the cyst. Histologically, the cyst was covered by two layers of muscle covered by the chorioepithelial columnar epithelium. EUS fine-needle aspiration is effective in diagnosing submucosal tumor but also carries the risk of infection. Contrast-enhanced ultrasonography was used in this case to observe the interior and reach a preoperative diagnosis. Contrast-enhanced harmonic EUS appears to be effective in examining the interior of submucosal tumor lesions noninvasively.
RESUMO
Objective Vonoprazan (VPZ), clarithromycin (CAM), metronidazole (MNZ) and VPZ, MNZ, and sitafloxacin (STFX) regimen are all established Helicobacter pylori eradication therapies for patients with penicillin allergy in Japan. However, no study has assessed the efficacy of a VPZ, CAM, and MNZ (VCM) regimen in patients with clarithromycin resistance (CAM-R). We therefore assessed the efficacy of a VCM regimen for treating H. pylori infection in patients with CAM-R and penicillin allergy. Methods Fifty-three patients with penicillin allergy who received H. pylori eradication therapy were retrospectively analyzed. Eight patients received a 7-day proton-pump inhibitor, CAM, and MNZ (PCM) regimen; 35 patients [11 CAM-R, and 10 with clarithromycin sensitivity (CAM-S)] received 7-day VCM regimens; and 10 patients received 7-day VPZ, MNZ, and STFX (VMS) regimens. A 13C-urea breath test was used to determine eradication. The efficacy of eradication was evaluated via both intention-to-treat (ITT) and per-protocol (PP) analyses. Results According to ITT and PP analyses, eradication rates (ERs) with PCM, VCM, and VMS therapies were 50.0% and 50.0%, 94.3% and 100%, and 90% and 90%, respectively. Treatment was successful in all patients with CAM-S. For patients with CAM-R, treatment was successful in 10 patients, and 1 patient discontinued treatment owing to an adverse event. According to ITT and PP analyses, ERs were 90.9% and 100% in CAM-R, and were 100% and 100% in CAM-S, respectively. Conclusion The VCM regimen for H. pylori eradication may be a viable candidate therapy for patients with penicillin allergy, regardless of CAM-R.
