RESUMEN
In this short communication, we discuss the recently described syndrome of retrograde cricopharyngeal dysfunction (R-CPD) with its first description in 2019 by the laryngologist Dr. Bastian. Diagnosis is generally based on typical clinical symptoms, e.g., the inability to belch, a bloated abdomen and retrosternal gurgling noises. We also describe high-resolution esophageal manometry as a new tool to further secure the diagnosis of RCPD, as well as therapeutic options such as botulinum toxin injections in the cricopharyngeal muscle or cricopharyngeal myotomy and the published data thereon.

Belching is the act of expelling air from the stomach or esophagus into the pharynx. Although the process is regarded as physiological, excessive belching might be associated with a significant burden for affected patients in the sense of a belching disorder. Diagnosis of a belching disorder is often challenging, and its differentiation from other conditions such as rumination syndrome, singultus, or aerophagia can be difficult. Treatment of these disorders also represents a challenge for otorhinolaryngologists. Hence, the aim of this review is to provide an interdisciplinary overview of these clinical syndromes and provide practical guidance for their diagnosis and treatment.

OBJECTIVE: Endoscopic pyloromyotomy (G-POEM) is a minimally invasive treatment option with promising uncontrolled outcome results in patients with gastroparesis. DESIGN: In this prospective randomised trial, we compared G-POEM with a sham procedure in patients with severe gastroparesis. The primary outcome was the proportion of patients with treatment success (defined as a decrease in the Gastroparesis Cardinal Symptom Index (GCSI) by at least 50%) at 6 months. Patients randomised to the sham group with persistent symptoms were offered cross-over G-POEM. RESULTS: The enrolment was stopped after the interim analysis by the Data and Safety Monitoring Board prior to reaching the planned sample of 86 patients. A total of 41 patients (17 diabetic, 13 postsurgical, 11 idiopathic; 46% male) were randomised (21 G-POEM, 20-sham). Treatment success rate was 71% (95% CI 50 to 86) after G-POEM versus 22% (8-47) after sham (p=0.005). Treatment success in patients with diabetic, postsurgical and idiopathic gastroparesis was 89% (95% CI 56 to 98), 50% (18-82) and 67% (30-90) after G-POEM; the corresponding rates in the sham group were 17% (3-57), 29% (7-67) and 20% (3-67).Median gastric retention at 4 hours decreased from 22% (95% CI 17 to 31) to 12% (5-22) after G-POEM and did not change after sham: 26% (18-39) versus 24% (11-35). Twelve patients crossed over to G-POEM with 9 of them (75%) achieving treatment success. CONCLUSION: In severe gastroparesis, G-POEM is superior to a sham procedure for improving both symptoms and gastric emptying 6 months after the procedure. These results are not entirely conclusive in patients with idiopathic and postsurgical aetiologies. TRIAL REGISTRATION NUMBER: NCT03356067; ClinicalTrials.gov.

Constipation is a common problem, affects 15% of the population, and is often self-diagnosed and self-managed. Over the past 3 decades, there have been significant advances in our understanding and management of chronic constipation, with the emerging recognition that occasional constipation (OC) is another subtype that falls outside current classifications. The purpose of this review was to describe the process of developing and proposing a new definition for OC based on expert consensus and taking into consideration the multifactorial nature of the problem such as alterations in bowel habit that include stool frequency and difficulty with stool passage, perception of the sufferer, duration of symptoms, and potential responsiveness to treatment. Leading gastroenterologists from 5 countries met virtually on multiple occasions through an online digital platform to discuss the problem of OC and recommended a practical, user-friendly definition: "OC can be defined as intermittent or occasional symptomatic alteration(s) in bowel habit. This includes a bothersome reduction in the frequency of bowel movements and/or difficulty with passage of stools but without alarming features. Bowel symptoms may last for a few days or a few weeks, and episodes may require modification of lifestyle, dietary habits and/or use of over-the-counter laxatives or bulking agents to restore a satisfactory bowel habit." Prospective studies are required to validate this definition and determine OC prevalence in the community. This review highlights current knowledge gaps and could provide impetus for future research to facilitate an improved understanding of OC and development of evidence-based management guidelines.

Single water swallow (SWS) high-resolution manometry (HRM) may miss relevant esophageal motility disorders. Solid test meal (STM) during HRM and lately the functional lumen imaging probe (FLIP) have been shown to be of diagnostic value in the assessment of motility disorders. We aimed to assess the diagnostic yield of STM and FLIP in non-obstructive dysphagia (NOD). Patients assessed for dysphagia with both HRM and FLIP between April 2016 and August 2019 were analyzed for signs of non-obstructive EGJ outflow obstruction (EGJOO) according to Chicago Classification 3.0 (CCv3) and CC adapted for the use with solid swallows (CC-S), followed by an individual group-specific analysis. Five subjects without dysphagia served as control group. Standard HRM- and FLIP-values as well as esophagograms and Eckardt Scores were analyzed. Forty-two patients were identified (male/female, 14/36, median age 62). Twenty-five (59.5%) were diagnosed with EGJOO during STM only (= SWS-negative patients; CC-S). The EGJ distensibility index (EGJ-DI) of symptomatic patients was significantly lower compared to the control group (p = 0.006). EGJ-DI was < 3mm2/mmHg in 67% and 88% of patients diagnosed according to CC-S and CCv3, respectively. The IRP during STM showed a significant association to the corresponding EGJ-DI values (p < 0.001). Seventy-six percent of patients received treatment because of additional STM evaluation with a favorable clinical response rate of 89%. STM and FLIP identify EGJOO in symptomatic patients with normal SWS during HRM. STM resembles an inexpensive and clinically meaningful option to diagnose motility disorders and helps to select patients for interventional treatment.

BACKGROUND AND AIMS: The role of decreased pyloric distensibility in gastroparesis as measured by the endolumenal functional luminal imaging probe (EndoFLIP) has been receiving increasing attention. In this study, we present clinical outcomes to pyloric dilation with the esophageal FLIP (EsoFLIP) in regard to gastric emptying, symptom evolution, and FLIP metrics. METHODS: Patients evaluated for gastroparesis (gastric emptying studies of t1/2 ≥180 minutes during 13C-octanoic acid breath test and/or gastric remnants during gastroscopy after a sufficient fasting period) were scheduled for EsoFLIP controlled pyloric dilation. Pre- and postprocedural gastric emptying studies, questionnaires (Patient Assessment of Upper GI Symptoms Severity Index [PAGI-SYM; including the Gastroparesis Cardinal Symptom Index] and Patient Assessment of Quality of Life Index [PAGI-QOL]), and FLIP metrics were documented. Dilation was conducted according to a self-developed algorithm. RESULTS: Forty-six patients were analyzed (72% women; median age, 39 years [range, 18-88]). Etiologies of gastroparesis were diabetic in 10 patients (22%), idiopathic in 33 (72%), and postoperative in 3 (6%). Postprocedural gastric emptying time decreased from a median of 211 minutes to 179 minutes (P = .001). In accordance, pyloric distensibility, PAGI-SYM, PAGI-QOL, and Gastroparesis Cardinal Symptom Index values improved significantly. After a median follow-up of 3.9 months, 57% of all treated patients with returned questionnaires reported improved symptoms. CONCLUSIONS: Pyloric EsoFLIP controlled dilation shows value in the treatment of gastroparesis, both subjectively and objectively. Long-term follow-up to assess efficacy and comparative trials are warranted.

BACKGROUND: Aeromonas hydrophila is a gram-negative facultative anaerobic coccobacillus, which is an environmental opportunistic pathogen. A. hydrophila are involved in several infectious diseases such as gastroenteritis, septicemia and wound infections. However, gastroenteritis caused by Aeromonas spp. are rare and the clinical relevance of Aeromonas species in stool specimens is still under debate. CASE PRESENTATION: Our case concerns a 32-year-old woman who presented at hospital with a worsening watery diarrhea and fever requiring intensive care. A cholera-like illness was diagnosed. The patient had a past history of an anti-Hu syndrome with a myenteric ganglionitis. A molecular multiplex RT-PCR (QIAstat-Dx Gastrointestinal Panel, QIAGEN) covering a broad spectrum of diverse gastrointestinal pathogens performed directly from the stool was negative but the stool culture revealed growth of A. hydrophila. Further investigations of the A. hydrophila strain in cell cultures revealed the presence of a cytotoxic enterotoxin. CONCLUSIONS: Although A. hydrophila rarely causes gastroenteritis, Aeromonas spp. should be considered as a causative agent of severe gastroenteritis with a cholera-like presentation. This case highlights the need to perform culture methods from stool samples when PCR-based methods are negative and gastrointestinal infection is suspected.

PURPOSE: Faecal incontinence (FI) is estimated to affect around 7.7% of people. There is a lack of uniformity in outcome definitions, measurement and reporting in FI studies. Until now, there is no general consensus on which outcomes should be assessed and reported in FI research. This complicates comparison between studies and evidence synthesis, potentially leading to recommendations not evidence-based enough to guide physicians in selecting an FI therapy. A solution for this lack of uniformity in reporting of outcomes is the development of a Core Outcome Set (COS) for FI. This paper describes the protocol for the development of a European COS for FI. METHODS: Patient interviews and a systematic review of the literature will be performed to identify patient-, physician- and researcher-oriented outcomes. The outcomes will be categorised using the COMET taxonomy and put forward to a group of patients, physicians (i.e. colorectal surgeons, gastroenterologists and general practitioners) and researchers in a Delphi consensus exercise. This exercise will consist of up to three web-based rounds in which participants will prioritise and condense the list of outcomes, which is expected to result in consensus. A consensus meeting with participants from all stakeholder groups will take place to reach a final agreement on the COS. DISCUSSION: This study protocol describes the development of a European COS to improve reliability and consistency of outcome reporting in FI studies, thereby improving evidence synthesis and patient care. TRIAL REGISTRATION: This project has been registered in the COMET database on the 1st of April 2020, available at http://www.comet-initiative.org/Studies/Details/1554 . The systematic review has been registered on the PROSPERO database on the 31st of August 2020, available at https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=202020&VersionID=1381336 .

BACKGROUND AND AIM: Previous studies have shown a reduction of gastrointestinal symptoms in irritable bowel syndrome (IBS) patients following a low FODMAP diet (LFD). It remains unknown which disorders of gut-brain interaction (DGBI) patients would benefit most from LFD. We aimed to analyze LFD response regarding a preceding nutrient challenge test (NCT). METHODS: Data of 110 consecutive DGBI patients undergoing NCT and LFD between August 2015 and August 2018 were analyzed retrospectively. LFD response was assessed by changes in IBS Symptom Severity Score (IBS-SSS). In mixed-effects linear regression models, the impact of hydrogen values and abdominal symptoms during NCT, performed with 30-g lactulose and 400-mL liquid test meal, on IBS-SSS changes were analyzed. RESULTS: Low FODMAP diet induced a significant IBS-SSS reduction of 78 points (95% confidence interval [CI] 50-96; P < 0.001). Patients with higher NCT-induced hydrogen increase during proximal intestinal transit had a significantly better LFD response (-66 IBS-SSS reduction per 10-ppm hydrogen increase, 95% CI -129 to -4, P = 0.045). Additionally, the higher the NCT-induced maximum hydrogen increase during mid-distal and distal intestinal transit, the better are the responses to LFD (-6 IBS-SSS per 10-ppm maximum delta hydrogen, 95% CI -11 to -1, P = 0.040). There was no association of LFD response with abdominal symptom generation during NCT. CONCLUSIONS: Our study is the first one analyzing and demonstrating significant associations between NCT results and LFD response. These findings are of high clinical importance, as they identify a subgroup of DGBI patients that may profit most from a restrictive LFD as first-line therapy.

The functional lumen imaging probe (FLIP) measures luminal dimensions using impedance planimetry, performed most often during sedated upper endoscopy. Mechanical properties of the esophageal wall and opening dynamics of the esophagogastric junction (EGJ) can be objectively evaluated in esophageal motor disorders, eosinophilic esophagitis, esophageal strictures, during esophageal surgery and in postsurgical symptomatic states. Distensibility index, the ratio of EGJ cross sectional area to intraballoon pressure, is the most useful FLIP metric. Secondary peristalsis from balloon distension can be displayed topographically as repetitive anterograde or retrograde contractile activity in the esophageal body, similar to high-resolution manometry. Real-time interpretation and postprocessing of FLIP metadata can complement the identification of esophageal outflow obstruction and achalasia, especially when findings are inconclusive from alternate esophageal tests in symptomatic patients. FLIP can complement the diagnosis of achalasia when manometry and barium studies are inconclusive or negative in patients with typical symptoms. FLIP can direct adequacy of disruption of the EGJ in achalasia when used during and immediately after myotomy and pneumatic dilation. Lumen diameter measured using FLIP in eosinophilic esophagitis and in complex strictures can potentially guide management. An abbreviated modification of the Grading of Recommendations Assessment, Development, and Evaluation was used to determine the quality of available evidence and recommendations regarding FLIP utilization. FLIP metrics that are diagnostic or suggestive of an abnormal motor pattern and metrics that define normal esophageal physiology were developed by consensus and are described in this review.

ESGE recommends the use of a graded pneumatic dilation protocol in achalasia, starting with a 30-mm dilation and followed by a 35-mm dilation at a planned interval of 2â-â4 weeks, with a subsequent 40-mm dilation when there is insufficient relief, over both a single balloon dilation procedure or the use of a larger balloon from the outset.Strong recommendation, high quality of evidence, level of agreement 100â%.ESGE recommends being cautious in treating spastic motility disorders other than achalasia with peroral endoscopic myotomy (POEM).Strong recommendation, very low quality of evidence, level of agreement 87.5â%.ESGE recommends against the routine use of botulinum toxin injections to treat patients with non-achalasia hypercontractile esophageal motility disorders (Jackhammer esophagus, distal esophageal spasm). However, if, in individual patients, endoscopic injection of botulinum toxin is chosen, ESGE recommends performing injections into four quadrants of the lower esophageal sphincter and in the lower third of the esophagus.Strong recommendation, low quality of evidence, level of agreement 78.6â%.ESGE recommends that endoscopic pylorus-directed therapy should be considered only in patients with symptoms suggestive of gastroparesis in combination with objective proof of delayed gastric emptying using a validated test, and only when medical therapy has failed.Strong recommendation, very low quality of evidence, level of agreement 100â%.ESGE recommends against the use of botulinum toxin injection in the treatment of unselected patients with gastroparesis. Strong recommendation, high quality of evidence, level of agreement 92.9â%.ESGE recommends consideration of gastric peroral endoscopic myotomy (G-POEM) in carefully selected patients only, because it is an emerging procedure with limited data on effectiveness, safety, and durability. G-POEM should be performed in expert centers only, preferably in the context of a clinical trial.Strong recommendation, low quality of evidence, level of agreement 100â%.

ESGE suggests flexible endoscopic treatment over open surgical treatment as first-line therapy for patients with a symptomatic Zenker's diverticulum of any size.Weak recommendation, low quality of evidence, level of agreement 100â%.ESGE recommends that emerging treatments for Zenker's diverticulum, such as Zenker's peroral endoscopic myotomy (Z-POEM) and tunneling, be considered as experimental; these treatments should be offered in a research setting only.Strong recommendation, low quality of evidence, level of agreement 100â%.ESGE recommends against the widespread clinical use of transoral incisionless fundoplication (TIF) as an alternative to proton pump inhibitor (PPI) therapy or antireflux surgery in the treatment of gastroesophageal reflux disease (GERD), because of the lack of data on the long-term outcomes, the inferiority of TIF to fundoplication, and its modest efficacy in only highly selected patients. TIF may have a role for patients with mild GERD who are not willing to take PPIs or undergo antireflux surgery.Strong recommendation, moderate quality of evidence, level of agreement 92.8â%.ESGE recommends against the use of the Medigus ultrasonic surgical endostapler (MUSE) in clinical practice because of insufficient data showing its effectiveness and safety in patients with GERD. MUSE should be used in clinical trials only.Strong recommendation, low quality evidence, level of agreement 100â%.ESGE recommends against the use of antireflux mucosectomy (ARMS) in routine clinical practice in the treatment of GERD because of the lack of data and its potential complications.Strong recommendation, low quality evidence, level of agreement 100â%.ESGE recommends endoscopic cecostomy only after conservative management with medical therapies or retrograde lavage has failed.Strong recommendation, low quality evidence, level of agreement 93.3â%.ESGE recommends fixing the cecum to the abdominal wall at three points (using T-anchors, a double-needle suturing device, or laparoscopic fixation) to prevent leaks and infectious adverse events, whatever percutaneous endoscopic cecostomy method is used.Strong recommendation, very low quality evidence, level of agreement 86.7â%.ESGE recommends considering endoscopic decompression of the colon in patients with Ogilvie's syndrome that is not improving with conservative treatment.Strong recommendation, low quality evidence, level of agreement 93.8â%.ESGE recommends prompt endoscopic decompression if the cecal diameter is >â12âcm and if the Ogilvie's syndrome exists for a duration of longer than 4â-â6 days.Strong recommendation, low quality evidence, level of agreement 87.5â%.

BACKGROUND AND AIM: Functional dyspepsia (FD) is a common disorder of gut-brain interaction with incompletely understood pathophysiology. Consequently, heterogeneous expert opinions on diagnostic tests and assessment of treatment efficacies exist. So far, no consensus about the most relevant diagnostic and outcome tool has been reached. In this study, we aimed to analyze the significance of a combined lactulose hydrogen breath test (LHBT) and liquid meal, yet representing a standardized test in irritable bowel syndrome (IBS), in FD. METHODS: We analyzed data of 146 FD, 204 IBS patients, and 50 healthy volunteers (HV). All patients underwent LHBT with a meal-drink consisting of 30-g Lactulose and 400-mL Ensure®. Effect of abdominal symptom generation in FD/IBS compared with HV was assessed on a patient-reported Likert-scale. RESULTS: There was a significant difference between FD/IBS patients and HV in LHBT-induced abdominal pain (odds ratio [OR] 246.9, 95% confidence interval [CI] 26.6-2290.7; OR 161.2, 95% CI 16.9-1534.8), abdominal bloating (OR 384.8, 95% CI 92.9-2135.4; OR 524.1, 95% CI 114.7-3432.3), borborygmi (OR 9.9, 95% CI 2.2-46.9; OR 17.7, 95% CI 4.7-67.4), nausea only in FD (OR 174.4, 95% CI 15.5-5375.5), and diarrhea in IBS only (OR 25.8, 95% CI 2.0-7012.6). Hydrogen production was not significantly different in FD/IBS and HV. CONCLUSIONS: In this study, we demonstrated significant differences in postprandial symptom generation in FD and IBS compared with HV after LHBT. This does not only allow us to discriminate FD/IBS from HV but may also represent a diagnostic and monitoring tool for FD/IBS in the future, including monitoring of treatment effects.

BACKGROUND & AIMS: Patients with irritable bowel syndrome (IBS) have an increased response of postprandial symptoms to a combined lactulose nutrient challenge test, compared with healthy volunteers. We investigated the associations among comorbid functional dyspepsia (FD), severity of psychologic symptoms, and breath test results in response to this test. METHODS: We performed a prospective study of 205 patients with IBS (Rome III criteria), 94 of whom also had FD (IBS-FD), and 83 healthy volunteers in Sweden from 2008 through 2015. All participants completed a breath hydrogen test after a 400-mL liquid meal with 25 g lactulose. Gastrointestinal (GI) symptom severity was assessed using a graded scale and digestive comfort was recorded before the meal and every 15 minutes until 240 minutes after the meal. GI symptom scores over time were compared between groups using linear mixed models with anxiety, depression, and somatization as covariates. RESULTS: Average levels of all GI symptoms varied over time among all groups (P < .0001). Patients with IBS-FD had higher levels of bloating (P = .004), abdominal pain (P = .005), and lower levels of digestive comfort (P < .01) than patients with only IBS. We observed a difference in increase in abdominal pain from baseline between IBS-FD and IBS groups (P = .013). Anxiety levels were associated with levels of all symptoms (all P < .025) except abdominal pain, which was associated with somatization severity (P < .0001). Furthermore, anxiety levels associated with level of exhaled hydrogen (P = .0042). CONCLUSIONS: In a prospective study of patients with IBS, we found those with FD to have increased GI symptoms before and after a liquid meal with lactulose. Anxiety and somatization have an independent additional effect. The presence of comorbid FD and levels of psychologic symptoms affect reports of food-related symptoms in patients with IBS.

BACKGROUND: Although the diagnostic process in celiac disease (CeD) has been addressed in several international guidelines, little is known about the actual proceeding in current clinical practice. This study investigated the initial presentation, the diagnostic process, follow-up evaluations, and adherence to a gluten-free diet in CeD patients in a real-life setting in Switzerland from a patient's perspective. METHODS: We performed a large patient survey among unselected CeD patients in Switzerland. RESULTS: A total of 1689 patients were analyzed. The vast majority complained of both gastrointestinal and nonspecific symptoms (71.5%), whereas 1.8% reported an asymptomatic disease course. A total of 35.8% CeD patients were diagnosed by a nongastroenterologist. The diagnostic process differed between nongastroenterologists and gastroenterologists, with the latter more often using duodenal biopsy alone or in combination with serology (94.7% vs. 63.0%) and nongastroenterologists more frequently establishing the diagnosis without endoscopy (37.0% vs. 5.3%, P<0.001). Follow-up serology after 6 months was performed only in half of all patients (49.4%), whereas 69.9% had at least 1 follow-up serology within the first year after diet initiation. About 39.7% had a follow-up endoscopy with duodenal biopsies (after a median of 12 mo; range, 1 to 600 mo). The likelihood of receiving any follow-up examination was higher in patients initially diagnosed by a gastroenterologist. CONCLUSIONS: A significant proportion of CeD patients are diagnosed by nongastroenterologists. Under the diagnostic lead of the latter, more than a third of the patients receive their diagnosis on the basis of a positive serology and/or genetics only, in evident violation of current diagnostic guidelines, which may lead to an overdiagnosis of this entity.

BACKGROUND: Obesity and gastroesophageal reflux disease (GERD) are commonly associated diseases. Bariatric surgery has been shown to have various impacts on esophageal function and GERD. Our aim was to evaluate changes in symptoms, endoscopic findings, bolus passage and esophageal function in patients after primary gastric bypass surgery as compared to patients converted from gastric banding to gastric bypass. METHODS: Obese patients scheduled for laparoscopic Roux-en-Y gastric bypass (naïve-to-bypass) and patients who previously underwent gastric banding and were considered for conversion from gastric banding to gastric bypass (band-to-bypass) were included. Patients rated esophageal and epigastric symptoms (100 point VAS) and underwent upper endoscopy, impedance-manometry, and modified "timed barium swallow" before/after surgery. RESULTS: Data from 66 naïve-to-bypass patients (51/66, 77 % females, mean age 41.2 ± 11.1 years) and 68 band-to-bypass patients (53/68, 78 % females, mean age 43.8 ± 10.0 years) were available for analysis. Esophageal symptoms, esophagitis, esophageal motility abnormalities and impaired esophageal bolus transit were more common in patients that underwent gastric banding compared to those that underwent gastric bypass. The majority of symptoms, lesions and abnormalities induced by gastric banding were decreased by conversion to gastric bypass. Esophagitis was present in 28/68 (41 %) and 13/47 (28 %) patients in the band-to-bypass group, pre- versus postoperatively, respectively, (p < 0.05). The percentage of swallows with normal bolus transit increased following transformation from gastric band to gastric bypass (57.9 ± 4.1 and 83.6 ± 3.4 %, respectively, p < 0.01). CONCLUSIONS: From an esophageal perspective, gastric bypass surgery induces less motility disorders and esophageal symptoms and should be therefore favored over gastric banding in difficult to treat obese patients at risk of repeated bariatric surgery.

BACKGROUND: Reverse sequence screening for syphilis, in which an automatable treponemal assay (enzyme immunoassay [EIA]/chemiluminescence assay [CIA]) is performed first and followed by a nontreponemal test for reactive specimens, has been used increasingly in the United States. The EIA is objective, efficient, and believed to be more sensitive than the rapid plasma reagin (RPR) because treponemal antibodies appear before nontreponemal antibodies. We sought to compare the sensitivity of a commonly used EIA, the Trep-Sure EIA (TS-EIA), to the RPR in cases of suspected primary syphilis infection in our clinic. METHODS: A retrospective medical record review of patients with sexually transmitted infection clinic visits from January 2009 to December 2011 was conducted, and 52 patients met the following inclusion criteria: suspected primary syphilis symptoms, at least 1 positive syphilis test result at visit, and no history of syphilis. Sensitivity analyses compared the TS-EIA and RPR, using the reference standard of concordantly positive/reactive TS-EIA/RPR or positive fluorescent treponemal antibody absorption test (FTA-ABS) result. We considered equivocal TS-EIA results to be positive for sensitivity calculations because such results typically reflex to additional testing and therefore may still result in identifying new infections. RESULTS: Twenty-eight (53.8%) of the 52 patients had a positive or equivocal TS-EIA. Twenty-five (89.3%) of those were RPR reactive; the remaining 3 (10.7%) were RPR nonreactive, FTA-ABS positive. Forty patients (76.9%) had a positive RPR, including 15 patients (37.5%) with negative TS-EIA results; all 15 were FTA-ABS positive. Nine additional patients were TS-EIA negative and RPR nonreactive but had a positive FTA-ABS result. The RPR was significantly more sensitive than the EIA (76.9% vs. 53.8%, P = 0.005). Trep-Sure EIA positivity was also significantly associated with higher median RPR titer (P = 0.011). CONCLUSIONS: Use of the TS-EIA may result in underdetection of primary syphilis compared with the RPR. Further evaluation of the sensitivity of the TS-EIA in high-morbidity settings is warranted before the adoption of reverse sequence screening algorithms.
