Introduction: Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) presents a therapeutic challenge with no currently definitive treatment, including therapeutic plasma exchange (TPE) and insulin. TPE aims to quickly reduce serum triglyceride (TG); however, its efficacy lacks convincing evidence. Intravenous insulin is a promising and convenient alternative, while comparative data is limited.

Methods: This retrospective, single-center study compared TPE and insulin treatment in HTG-AP patients. The primary outcome measured was the percentage of TG reduction within 48 hours of admission.

Results: The study included 33 TPE-treated and 56 insulin-treated patients. The TPE groups were more severe than those with medical therapy at baseline characteristics. A trend towards higher TG reduction within 24 hours was observed in the TPE group (62.5% [IQR 51.7-83.3] vs. 55.7% [IQR 34.2-74.7], p = 0.038). However, no significant difference in TG reduction at 48 hours was found between insulin and TPE groups (83.6% and 81.9%, respectively, p = 0.715). The TPE group exhibited extended hospital stays (10.0 [IQR 7.0-13.5] days vs. 6.0 [4.0-8.7] days, p = 0.001) without any difference in in-hospital mortality or time needed to lower TG below < 11.3 mmol/L.

Conclusion: In patients with HTG-AP, TPE decreased plasma triglyceride levels faster in the first 24 hours than insulin therapy. However, there was no significant advantage after 48 hours. Therefore, insulin may be a promising alternative and convenient treatment in carefully selected patients with HTG-AP.

Introduction: The beneficial effects of using antidepressants in improving functional dyspepsia (FD) symptoms have been reported in previous meta-analyses; however, the results have not been conclusive. The aim was to perform an updated meta-analysis coupled with trial sequential analysis (TSA) to assess the efficacy of the use of any antidepressants in the treatment of FD in adults.

Methods: Electronic databases were searched up to March 2024 for randomized controlled trials (RCTs) recruiting adults with FD. Data of overall symptoms improved between the antidepressants and placebo groups was pooled to obtain risk ratio (RR) employing the random-effects model. The effect of random errors was evaluated with TSA. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence. Analyses were performed using STATA version 16.0.

Results: Nine RCTs with 924 patients met the eligible criteria. The RRs of FD symptoms improving with any antidepressants, tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors were (n = 9, RR = 1.30 [95% CI, 1.02-1.67]), (n = 5, RR = 1.41 [95% CI, 1.07-1.85]) and (n = 2, RR = 0.97 [95% CI, 0.72-1.29]), respectively. TSA demonstrated conclusive evidence for the beneficial effect of TCAs. The number needed to treat (NNT) with any depressants and TCAs were 11 (95% CI, 7-36) and 6 (95% CI, 4-15), respectively. The certainty of the evidence for an effect of TCAs was that of moderate GRADE quality. The benefit, however, was limited to the western population (n = 3, RR = 1.43 [95% CI, 1.04-1.96]) and did not extend to the Asian population (n = 2, RR = 1.32 [95% CI, 0.75-2.32]). Conversely, antidepressant-using patients experienced adverse events more frequently. However, no statistically significant association was found between TCAs and any adverse events (n = 3; RR = 1.36 [95% CI, 0.91-2.04]).

Conclusion: Evidence was obtained suggesting TCAs can be an effective alternative in the treatment of FD, but more evidence from high-quality large trials is required to support their use, especially in the Asian population.

Background and aims: Gastroesophageal reflux disease (GERD) is classified into erosive reflux disease (ERD) and non-erosive reflux disease (NERD). NERD includes three phenotypes: true NERD, functional heartburn (FH) and reflux hypersensitivity (RH). The management of these NERD phenotypes differs. We aimed at studying the spectrum of high-resolution manometry (HRM) and 24-hour impedance-pH findings in Indian patients with NERD, classifying the phenotypes and assessing the response to phenotype-based treatment.

Methods: We prospectively studied the clinical characteristics, endoscopy, HRM, 24-hour impedance-pH findings, symptom association and response to phenotype-specific treatment in patients with NERD.

Results: Of 53 patients with NERD, the following phenotypes were diagnosed namely: 35 (66%) true NERD, 12 (22.7%) RH and six (11.3%) FH. The esophagogastric junction-contractile integral (EGJ-CI) was low in 60.4% and ineffective esophageal motility (IEM) was present in 53% of patients. The respective median values for true NERD, RH and FH groups were as follows: proximal mean nocturnal baseline impedance (P-MNBI) 2250Ω, 2241Ω, 2550Ω, (p = 0.592), distal (D-MNBI) 1431Ω, 2887.5Ω, 2516Ω (p < 0.001), post-reflux swallow-induced peristaltic wave index (PSPWI) 11.1%, 16%, 18.7% (p = 0.127). Receiver operating characteristic (ROC) curve analyses showed that D-MNBI and PSPWI discriminated FH and RH from true NERD, respectively, with a cut-off of 2376.5Ω (area under curve [AUC]:0.919, p < 0.001), 22.6% (AUC:0.671, p = 0.184) and 2318Ω (AUC:0.919, p =  < 0.001), 16.2% (AUC:0.671, p = 0.079). The median P-MNBI was lower in patients with GERD-associated cough than other symptoms 1325 (1250, -). Fifty (94.3%) patients showed significant improvement in symptom severity scores (p < 0.001) following phenotype-specific treatment.

Conclusions: In NERD patients, EGJ-CI and IEM were low. D-MNBI and PSPWI could effectively discriminate true NERD from FH and RH, whereas P-MNBI could help diagnose GERD-associated cough. The phenotype-specific treatment provides better symptom relief for patients.

Background and aim: Achalasia cardia, a primary motility disorder of the esophagus, poses significant malnutrition risks. This study aims at comprehensively assessing the nutritional status in untreated achalasia patients, contrasting it with functional gastrointestinal disorders (FGIDs) cases and impact of per-oral endoscopic myotomy (POEM) on nutrition at one-year.

Methods: We conducted a prospective study, including consecutive achalasia cases, from December 2021 to April 2022 at a tertiary care centre. Biochemical parameters, anthropometry, subjective global assessment (SGA) and malnutrition universal screening tool were used for nutritional assessment. Cases diagnosed with FGIDs served as controls.

Results: As many as 118 cases (41.2 ± 13.9 years, 61% males) with achalasia and 200 controls (43.4 ± 11.9 years, 69% males) were included in the study. Sub-types of achalasia included type I (16.9%), II (76.3%) and III (6.8%). Overall, 38.1% and 6.8% cases were moderately and severely malnourished, respectively. As compared to controls, cases with achalasia had lower pre-albumin (19.4 vs. 25.2; p = 0.001), serum calcium (p = 0.012), vitamin D (p = 0.001), serum iron (p = 0.001), triceps fold thickness (p = 0.002) and hand-grip strength (p = 0.001). On univariate analysis, type-I achalasia, body mass index, % weight loss, lower esophageal sphincter pressures and Eckardt scores were predictors of malnourishment (SGA). On multivariate analysis, type of achalasia, mid arm circumference and low body mass index were significant predictors of malnourishment in cases with achalasia. There was significant improvement in the nutritional status after POEM at one-year follow-up.

Conclusion: Achalasia patients demonstrate a notably higher risk of malnutrition compared to individuals with FGIDs. Nutritional status significantly improves after POEM. (NCT05161923).
