INTRODUCTION: Epidural steroid injections are an integral part of nonsurgical management of radicular pain from lumbar spine disorders. We studied the effect of dexamethasone 8 mg epidural injections on the hypothalamic-pituitary-adrenal axis and serum glucose control of Asian patients. METHODS: 18 patients were recruited: six diabetics and 12 non-diabetics. Each patient received a total of dexamethasone 8 mg mixed with a local anaesthetic solution of lignocaine or bupivacaine, delivered into the epidural space. Levels of plasma cortisol, adrenocorticotropic hormone (ACTH), serum glucose after an overnight fast and two-hour postprandial glucose, as well as weight, body mass index, blood pressure and heart rate were measured within one week prior to the procedure (baseline) and at one, seven and 21 days after the procedure. RESULTS: Median fasting blood glucose levels were significantly higher on post-procedure Day 1 than at baseline. However, there was no significant change in median two-hour postprandial blood glucose from baseline levels. At seven and 21 days, there was no significant difference in fasting or two-hour postprandial glucose levels. Both ACTH and serum cortisol were significantly reduced on Day 1 compared to baseline in all patients. There was no significant difference in ACTH and serum cortisol levels from baseline at Days 7 and 21. CONCLUSION Our study shows that epidural steroid injections with dexamethasone have a real, albeit limited, side effect on glucose and cortisol homeostasis in an Asian population presenting with lower back pain or sciatica.

BACKGROUND/AIMS: The prevalence and severity of irritable bowel syndrome (IBS) declines with age, but the cause of this is unknown. This study tested 2 hypotheses: (1) autonomic nervous system responses to eating and bowel distention, measured by heart rate variability (HRV), differs by age in IBS patients and (2) HRV is correlated with colonic motility and IBS symptoms. METHODS: One hundred and fifty-six Rome III positive IBS patients and 31 healthy controls underwent colonic manometry with bag distention in the descending colon, followed by ingestion of an 810-kcal meal. HRV, evaluated by low frequency (%LF; 0.04–0.15 Hz) component, high frequency (%HF; 0.15–0.40 Hz) component, and the LF/HF ratio, was measured during colonic distention and after the meal. Motility index and subjective symptom scores were simultaneously quantified. RESULTS: Both colonic distention and eating decreased %HF and increased the LF/HF ratio, and both indices of autonomic nervous system correlated with age. In IBS patients, %HF negatively correlated with the postprandial motility index after adjusting for age. The %HF and LF/HF ratios also correlated with psychological symptoms but not bowel symptoms in IBS patients. CONCLUSION: Decreased vagal activity is associated with increase in age and greater postprandial colonic motility in patients with IBS, which may contribute to postprandial symptoms.

BACKGROUND/AIMS: DA-9701 is a novel prokinetic agent. In the present study, we investigated the effect of DA-9701 on the motility of the gastric antrum in the normal and clonidine-induced hypomotility in an in vivo animal model. METHODS: A strain gauge force transducer was sutured on the gastric antrum to measure the contractile activity in rats. A total of 28 rats were subclassified into the 4 groups: (1) the placebo group, (2) the DA-9701 group, (3) the placebo group in the clonidine-pretreated rats, and (4) the DA-9701 group in the clonidine-pretreated rats. After the basal recording, either placebo (3% [w/v] hydroxypropylmethyl cellulose) or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. In the clonidine-pretreated rats, either placebo or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. RESULTS: Oral administration of DA-9701 did not significantly alter the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the placebo group. The administration of clonidine decreased the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the administration of placebo. This reduction of the antral motility by the administration of clonidine was not observed in the clonidine-pretreated DA-9701 group. The percentage of the motility index in the postprandial period was significantly greater in the clonidine-pretreated DA-9701 group, compared with the clonidine-pretreated placebo group. CONCLUSIONS: DA-9701 improves the hypomotility of the gastric antrum induced by clonidine, suggesting its gastroprokinetic effect in the pathologic condition.

Diabetes mellitus is a progressive metabolic disease and if left untreated, it is associated with failure of various organs. The search of safer antidiabetic agents leads to research of traditional medicinal plants.
OBJECTIVE: This study aimed to determine the effect of Abelmoschus esculentus water on the postprandial blood sugar among healthy normal human subjects.
METHOD: Randomized Open-Label Study. Normal healthy volunteers 20-60 years of age were recruited at Ospital ng Maynila Medical Center. After an overnight fast, FBS measurements were recorded. The were then randomized to Okra water and placebo. Both groups were also fed a standard meal in addition to the water of their respective groups. Capillary blood glucose was measured. after 2 hours and 4 hours. The difference in in the blood glucose of both groups was compared.
RESULTS: The mean random blood sugar of the subjects after intake of standard meal 2 hour postprandial in okra water group (109.92 ± 9.45 mg/dl) is greater than in the placebo group (108.35 ± 9.93 mg/dl), but not statistically significant (p>0.05). Also, the mean RBS 4 hours postprandial is less in okra water group than in placebo group (95.23 ± 6.99 versus 96.40 ± 9.13 mg/dl) but is also not statistically significant (p>0.05). Overall, the mean blood sugar of the okra water group from baseline to postprandial has no significant difference as compared to placebo.
CONCLUSION: Contrary to the previous animal studies, this present study, which used human subjects, showed no significant difference n the postprandial blood sugar level on subjects given with A. esculentus water as compared to placebo.

BACKGROUNDThe conventional approaches to diabetes screening are potentially limited by poor compliance and laboratory demand. This study aimed to evaluate the performance of fasting plasma glucose (FPG) and postprandial urine glucose (PUG) in screening for diabetes in Chinese high-risk population.

METHODSNine hundred and nine subjects with high-risk factors of diabetes underwent oral glucose tolerance test after an overnight fast. FPG, hemoglobin A1c, 2-h plasma glucose (2 h-PG), and 2 h-PUG were evaluated. Diabetes and prediabetes were defined by the American Diabetes Association criteria. The area under the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic accuracy of 2 h-PUG, and the optimal cut-off determined to provide the largest Youden index. Spearman correlation was used for relationship analysis.

RESULTSAmong 909 subjects, 33.4% (304/909) of subjects had prediabetes, and 17.2% (156/909) had diabetes. The 2 h-PUG was positively related to FPG and 2 h-PG (r = 0.428 and 0.551, respectively, both P < 0.001). For estimation of 2 h-PG ≥ 7.8 mmol/L and 2 h-PG ≥ 11.1 mmol/L using 2 h-PUG, the area under the ROC curve were 0.772 (95% confidence interval [CI ]: 0.738-0.806) and 0.885 (95% CI: 0.850-0.921), respectively. The corresponding optimal cut-offs for 2 h-PUG were 5.6 mmol/L and 7.5 mmol/L, respectively. Compared with FPG alone, FPG combined with 2 h-PUG had a higher sensitivity for detecting glucose abnormalities (84.1% vs. 73.7%, P < 0.001) and diabetes (82.7% vs. 48.1%, P < 0.001).

CONCLUSIONFPG combined with 2 h-PUG substantially improves the sensitivity in detecting prediabetes and diabetes relative to FPG alone, and may represent an efficient layperson-oriented diabetes screening method.

BACKGROUND/AIMS: Postprandial symptoms of fullness and abdominal discomfort are common after fatty meals. Gastric lipases hydrolyze 10% to 20% of dietary triglycerides during the stomach trituration period of digestion. The aim of this study was to evaluate the effects of acid-resistant lipase on upper gastrointestinal symptoms, including fullness and bloating, as well as on gastric myoelectrical activity after healthy subjects ingested a high-fat, liquid meal. METHODS: This study utilized a double-blind, placebo-controlled, crossover design with 16 healthy volunteers who ingested either a capsule containing 280 mg of acid-resistant lipase or a placebo immediately before a fatty meal (355 calories, 55% fat). Participants rated their stomach fullness, bloating, and nausea before and at timed intervals for 60 minutes after the meal. Electrogastrograms were obtained to assess the gastric myoelectrical activity. RESULTS: Stomach fullness, bloating, and nausea increased significantly 10 minutes after ingestion of the fatty meal (p<0.01), whereas normal gastric myoelectrical activity decreased and tachygastria increased (p<0.05). With lipase, reports of stomach fullness were significantly lower compared with placebo (p<0.05), but no effect on gastric myoelectrical activity or other upper gastrointestinal symptoms was observed. CONCLUSIONS: The high-fat meal induced transient fullness, bloating, nausea, and tachygastria in healthy individuals, consistent with post-prandial distress syndrome. Acid-resistant lipase supplementation significantly decreased stomach fullness.

PURPOSE: The aim of this study was to evaluate bolus transit during esophageal swallow (ES) and gastroesophageal reflux (GER) events and to investigate the relationship between the characteristics of ES and GER events in a population of term and preterm newborns with symptoms of gastroesophageal reflux disease (GERD). METHODS: The study population consisted of term and preterm newborns referred to combined multichannel intraluminal impedance (MII) and pH monitoring for GERD symptoms. The frequency and characteristics of ES and GER events were assessed by two independent investigators. Statistical significance was set at p<0.05. RESULTS: Fifty-four newborns (23 preterm) were included in the analyses. Median bolus head advancing time corrected for esophageal length (BHATc) was shorter during mealtime than during the postprandial period (median, interquartile range): 0.20 (0.15-0.29) s/cm vs. 0.47 (0.39-0.64) s/cm, p<0.001. Median bolus presence time (BPT) was prolonged during mealtime: 4.71(3.49-6.27) s vs. 2.66 (1.82-3.73) s, p<0.001. Higher BHATc (p=0.03) and prolonged BPT (p<0.001) were observed in preterm newborns during the postprandial period. A significant positive correlation between BHATc and bolus clearance time was also observed (rho=0.33, p=0.016). CONCLUSION: The analysis of ES and GER events at the same time by MII provides useful information to better understand the physiopathology of GERD. In particular, the analysis of BHATc during the postprandial period could help clinicians identify newborns with prolonged esophageal clearance time due to impaired esophageal motility, which could allow for more accurate recommendations regarding further tests and treatment.

BACKGROUND/AIMS: Functional dyspepsia (FD) is a gastrointestinal disorder in which the patient suffers from chronic abdominal symptoms despite the absence of organic disease. Benachio Q solution (soln.)(R) is a new prokinetic herbal medicine. The aim of the present study is to determine the efficacy and safety of Benachio Q soln.(R) in patients with postprandial distress syndrome (PDS) subtype in FD. METHODS: A single-center, randomized, double-blind, placebo-controlled pilot study was performed in 20 patients with PDS. Patients were assigned to receive either Benachio Q soln.(R) or placebo three times a day. After 4 weeks of treatment, the data on response rates, symptoms severity of PDS and gastric emptying time were analyzed to evaluate its efficacy. Adverse events, laboratory tests and vital sign were analyzed to assess its safety. RESULTS: Nine patients were assigned to Benachio group and 10 patients to placebo group. The response rate after 4 weeks was 44.4% and 20.0% in Benachio and placebo group, respectively (p=0.350). The response rate during the first week in Benachio group was better compared to that of placebo group with marginal difference (33.3% vs. 0.0%, p=0.087). Changes of severity score in early satiety on second and third week were -1.8+/-0.6, -1.9+/-0.4 and -1.3+/-0.5, -1.4+/-0.6 in Benachio and placebo group, respectively (p=0.059 vs. p=0.033). No adverse event was observed. CONCLUSIONS: The new herbal drug, Benachio Q soln.(R) seems to improve the symptoms of PDS subtype in FD and could be used safely. Further larger trial is needed in the future.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduce glycosylated hemoglobin (HbA1c, 0.5% to 1.0%), and are associated with moderate weight loss and a relatively low risk of hypoglycemia. There are differences between Asian and non-Asian populations. We reviewed available data on GLP-1RAs, focusing on Korean patients, to better understand their risk/benefit profile and help inform local clinical practice. Control of postprandial hyperglycemia is important in Asians in whom the prevalence of post-challenge hyperglycemia is higher (vs. non-Asians). The weight lowering effects of GLP-1RAs are becoming more salient as the prevalence of overweight and obesity among Korean patients increases. The higher rate of gastrointestinal adverse events amongst Asian patients in clinical trials may be caused by higher drug exposure due to the lower body mass index of the participants (vs. non-Asian studies). Data on the durability of weight loss, clinically important health outcomes, safety and optimal dosing in Korean patients are lacking. Use of GLP-1RAs is appropriate in several patient groups, including patients whose HbA1c is uncontrolled, especially if this is due to postprandial glucose excursions and patients who are overweight or obese due to dietary problems (e.g., appetite control). The potential for gastrointestinal adverse events should be explained to patients at treatment initiation to facilitate the promotion of better compliance.

OBJECTIVETo evaluate the efficacy and safety of "Three-Typed Syndrome Differentiation" (TTSD) in treating type 2 diabetes mellitus patients.

METHODSA systematic review and meta-analysis was done based on the clinical diabetes treatment literature of the "TTSD". Overseas databases like the PubMed/MEDLINE, EMBASE, Cochrane Library and Cochrane Central Register of Controlled Clinical Trials, and China databases like China Biology Medicine Disc (CBM), Chinese national Knowledge Infrastructure (CNKI), Wanfang database, and VIP database, without limitation on language, were included with the time limitation from Jan 1982 to Dec 2012 by retrieval of relative original clinical research articles.

RESULTSNineteen articles where contains 1,840 diabetes patients were obtained, in which no adverse reactions were reported. Of these, 14 literatures involved the effect of fasting blood glucose (FBG), 10 involved that of postprandial 2-h blood glucose (P2hBG), and 19 involved the overall efficacy based on the national Chinese medicine (CM) diagnosis and treatment standard of diabetes. All the meta-analysis results prefer to the "TTSD" groups (CM+Western medicine Based on TTSD). The results show that, beside the efficacy of Western medicine, the concentrations of FBG and P2hBG in "TTSD" groups continue to drop with statistical significance. For "TTSD" groups, the FBG subsequently dropped 1.03 mmol/L, 95%CI [1.24,0.82] P <0.00001), the P2hBG subsequently dropped 1.09 mmol/L, 95% CI [1.61, 0.57] (P <0.0001), and the overall efficacies benefit 3.46 times those of Western medicine alone, 95% CI [2.67,4.48] (P <0.00001).

CONCLUSIONSThe CM by the diagnosis and treatment of type 2 diabetes based on TTSD might be safe and effective, and could better improve both blood glucose and the overall status of patients, including symptoms.
