The clinical significance of antichlamydial antibodies (Chlam Ab) was determined in a total of 1303 subfertile couples consulting for infertility investigation and treatment. Median age of the women was 30 (range 22-44) years and of the men 33 (range 21-53) years. The median duration of infertility was 4 (range 1-21) years. All patients were asymptomatic for genital tract infection. A comprehensive infertility investigation included examination of the endocrine, cervical, and tubal factor, and semen analysis, antisperm antibody (ASA) testing, sperm-mucus interaction testing in vitro using a standardized protocol, and post-coital testing (PCT). Screening for Chlam IgG Ab was performed in serum of both partners, obtained at the same time. Simultaneous microbial cultures in genital secretions of both partners included a broad spectrum of potentially pathogenic bacteria. Elevated titres of Chlam IgG Ab as seromarker for previous infection were found in 20.8% of all women, and in 12.6% of men. Chlam Ab were significantly more frequent in partners of seropositive patients (in 51.8% of women with a Chlam Ab positive partner, compared to 15.8% of the other women). Microbial screening outcome was not significantly related to results of chlamydial serology in both partners. In women, elevated titres of Chlam Ab were significantly associated with a tubal factor, but were not related to reduced quality of the endocervical mucus (CM), including the in-vitro penetrability of the CM (using partners' or donors' spermatozoa). In males, Chlam Ab were not significantly related to the outcome of semen analysis, including screening for ASA (IgG and/or IgA) in semen, and several parameters of sperm functional capacity. After exclusion of couples with tubal disease, subsequent male fertility did not significantly differ in males with or without Chlam Ab. The results suggest that during basic infertility investigation, positive chlamydial serology as an easy screening procedure indicates a higher risk for a tubal infertility factor. However, in asymptomatic patients, Chlam IgG Ab in serum are not associated with a cervical factor or with the male factor, using several determinants for evaluation of semen quality including subsequent fertilizing capacity.

The cervical inlet patch is an island of heterotopic gastric mucosa, most commonly found in the proximal oesophagus. Its importance as a cause of throat symptoms has been recognised, particularly chronic globus sensation. This has led to a change in the Rome IV criteria for globus management, with emphasis on ruling out the condition. Proton pump inhibitors are often ineffective in resolving symptoms. Endoscopic studies on the use of ablative techniques, most recently radiofrequency ablation (RFA), have shown promise in reversing the CIP to mormal squamous mucosa, with subsequent symtpomatic resolution. The aim of this review is to update on the investigation and management of the CIP.

Background and AimAcute gastrointestinal bleeding carries poor outcomes unless prompt endoscopic hemostasis is achieved. Mortality in these patients remains significant. Hemospray is a novel intervention that creates a mechanical barrier over bleeding sites. We report the largest dataset of patient outcomes after treatment with Hemospray from an international multicenter registry.Patients and MethodsProspective data (Jan 2016–May 2018) from 12 centers across Europe were collected. Immediate hemostasis was defined as endoscopic cessation of bleeding within 5 min after application of Hemospray. Rebleeding was defined as subsequent drop in hemoglobin, hematemesis, persistent melena with hemodynamic compromise post‐therapy.ResultsThree hundred and fourteen cases were recruited worldwide (231 males, 83 females). Median pretreatment Blatchford score was 11 (IQR: 8–14) and median complete Rockall score (RS) was 7 (IQR: 6–8) for all patients. Peptic ulcer disease (PUD) was the most common pathology (167/314 = 53%) and Forrest Ib the most common bleed type in PUD (100/167 = 60%). 281 patients (89.5%) achieved immediate hemostasis after successful endoscopic therapy with Hemospray. Rebleeding occurred in 29 (10.3%) of the 281 patients who achieved immediate hemostasis. Seven‐day and 30‐day all‐cause mortality were 11.5% (36/314) and 20.1% (63/314), respectively (lower than the predicted rates as per the RS). Similar hemostasis rates were noted in the Hemospray monotherapy (92.4%), combination therapy (88.7%) and rescue therapy (85.5%) groups.ConclusionsThese data show high rates of immediate hemostasis overall and in all subgroups. Rebleeding and mortality rates were in keeping/lower than predicted rates.

ObjectiveAcid exposure time (AET) from ambulatory pH studies and reflux oesophagitis are independent measurements used by the Lyon classification to diagnose GORD. This study aimed to validate AET reference ranges and diagnostic thresholds by analysis of 96-hour wireless pH studies from healthy, asymptomatic controls (HCs) and patients with and without oesophagitis.DesignHC and consecutive patients referred for wireless pH studies (off acid suppressants for >7 days) underwent 96-hour pH studies at two tertiary referral centres. Erosive oesophagitis was categorised by the Los Angeles (LA) classification. Linear regression and receiver operating curve (ROC) analysis were performed to define optimal diagnostic cut-offs.ResultsProlonged, 96-hour pH studies were completed in 39 HCs (age 28 (18–53) years, 72% female) and 944 patients (age 46 (16–85) years, 65% female), of whom 136 (14.5%) had reflux oesophagitis. Median AET in HC was 1.3% (upper 95th percentile 4.6%) for any study day and 2.6% (upper 95th percentile 6.9%) for the worst day (24-hour period) during the study. ROC analysis for average AET differentiated HC from patients with moderate-to-severe oesophagitis (LA BCD; sensitivity 87%, specificity 95%, positive predictive value (PPV) 59%, negative predictive value 99% for a cut-off AET of 4.3%; area under the receiver operating curve 0.95). Specificity was higher, but PPV was substantially lower for severe oesophagitis (LA CD). ‘Worst-day’ analysis provided similar results; however, day-to-day variability was high.ConclusionDiagnostic thresholds for average AET were identified that accurately discriminate between HCs and patients with erosive oesophagitis. The findings provide conditional support for diagnostic criteria for GORD proposed by the Lyon Consensus.

In asymptomatic infertility patients, no significant relationship was found between the presence of antisperm antibodies (ASA) in ' serum and in semen samples (IgG and/or IgA ASA), differentiated with the mixed antiglobulin reaction (MAR), and the microbial colonization of ejaculates covering a broad spectrum of microorganisms. Likewise, there was no significant association of ASA with microbial findings in patients' female partners, who also presented without symptoms of genital tract infection and were screened at the same time. Furthermore, ASA in semen (IgG and IgA) were not significantly related to several potential markers of subclinical male sexual gland infection or inflammation (leukocytes, PMN elastase, albumin, CSc) evaluated in aliquots of the same ejaculates used for immunological testing.

Summary Background Although nighttime reflux symptoms are common, the presence of nocturnal reflux is seldom confirmed with a standard 24 hours pH study. Aim To study patients with supine nighttime reflux symptoms using prolonged wireless pH monitoring. Methods In this retrospective study, patients with typical acid reflux symptoms were studied using 96‐h pH monitoring. Patients with nighttime reflux symptoms were compared to those without. Night‐to‐night variability and diagnostic accuracy of 24‐, 48‐ and 72‐hours pH studies compared to the 96‐hours “gold standard” were evaluated. Results Of the 105 included patients (61.9% females; mean age 46.8 ± 14.4 years), 86 (81.9%) reported nighttime reflux symptoms, of which 67.4% had pathological supine nocturnal acid exposure in at least one night. There was high variance in night‐to‐night acid exposure (94% [IQR0‐144]), which was larger than the variance in upright acid exposure (58% [IQR32‐88]; P < 0.001). When analysing the first 24 hours of the pH study, 32% of patients were diagnosed with pathological supine nighttime acid exposure versus 51% of patients based upon the 96‐hours pH‐test. The diagnostic accuracy and yield improved with study duration (P < 0.001). Reflux episodes with a lower nadir pH or longer acid clearance time were more prone to provoke nightly symptoms. Conclusions The majority of patients with nocturnal reflux symptoms had pathological acid exposure in at least one night of the prolonged pH recording. A high night‐to‐night variability in acid exposure reduces the clinical value and diagnostic yield of pH monitoring limited to 24 hours. Prolonged testing is a more appropriate diagnostic tool for patients with nocturnal reflux symptoms.
