BACKGROUND/AIM
Amitriptyline is a major tricyclic antidepressant that is also used to relieve chronic orofacial pain. Recently, alterations in gut flora due to various antidepressants have been demonstrated. However, it remains unknown how antidepressants affect the oral environment, including microbiota and innate immunity. The aim of this study was to investigate the effects of amitriptyline on oral microflora and antimicrobial peptides.
MATERIALS AND METHODS
Sprague-Dawley rats were intraperitoneally injected with amitriptyline for 2 weeks. The DNA extracted from the oral swabs were used to perform 16SrRNA sequencing to evaluate the oral microbiome. Quantitative RT-PCR was performed to evaluate the mRNA levels of antimicrobial peptides in the buccal tissues.
RESULTS
No significant differences in salivary flow rates were observed between the amitriptyline and control groups. Taxonomic analysis showed significant alterations in bacteria such as Corynebacterium, Rothia, and Porphyromonas due to amitriptyline administration. The beta diversity showed significant differences between the amitriptyline and control groups. Additionally, the predicted metagenome functions were significantly different between the two groups. The mRNA expression levels of antimicrobial peptides in the amitriptyline group were significantly higher as compared to controls.
CONCLUSION
Systemic administration of amitriptyline may affect the oral environment, including oral microbes and innate immunity in the oral mucosa.

Alcoholic (ASH) and nonalcoholic. (NASH).steatohepatitis are advanced.stages.of.fatty.liver.disease.Methionine adenosyltransferase 1A (MAT1A) plays a key role in hepatic methionine metabolism and germline Mat1a deletion in mice promotes NASH. Acid sphingomyelinase (ASMase) triggers hepatocellular apoptosis and liver fibrosis and has been shown to downregulate MAT1A expression in the context of fulminant liver failure. Given the role of ASMase in steatohepatitis development, we investigated the status of ASMase in Mat1a mice and the regulation of ASMase by SAM/SAH. Consistent with its role in NASH, Mat1a mice fed a choline-deficient (CD) diet exhibited macrosteatosis, inflammation, fibrosis and liver injury as well as reduced total and mitochondrial GSH levels. Our data uncovered an increased basal expression and activity of ASMase but not neutral SMase in Mat1a mice, which further increased upon CD feeding. Interestingly, adenovirus-mediated shRNA expression targeting ASMase reduced ASMase activity and protected Mat1a mice against CD diet-induced NASH. Similar results were observed in CD fed Mat1a mice by pharmacological inhibition of ASMase with amitriptyline. Moreover, Mat1a/ASMase double knockout mice were resistant to CD-induced NASH. ASMase knockdown protected wild type mice against NASH induced by feeding a diet deficient in methionine and choline. Furthermore, Mat1a mice developed acute-on-chronic ASH and this outcome was ameliorated by amitriptyline treatment. In vitro data in primary mouse hepatocytes revealed that decreased SAM/SAH ratio increased ASMase mRNA level and activity. MAT1A and ASMase mRNA levels exhibited an inverse correlation in liver samples from patients with ASH and NASH. Thus, disruption of methionine metabolism sensitizes to steatohepatitis by ASMase activation via decreased SAM/SAH. These findings imply that MAT1A deletion and ASMase activation engage in a self-sustained loop of relevance for steatohepatitis.

Journal of Oral & Facial Pain and... 2022To evaluate the efficacy and safety of melatonin for migraine prophylaxis in adults. (Meta-Analysis)
Meta-Analysis
AIMS
To evaluate the efficacy and safety of melatonin for migraine prophylaxis in adults.
METHODS
After a comprehensive literature search in the MEDLINE, Cochrane Database, and International Clinical Trial Registry Platform databases, reviewers extracted data from three relevant articles. PRISMA guidelines were followed in the selection, analysis, and reporting of the findings. Quality assessment was performed using the Cochrane risk of bias assessment tool. A random-effects model was used to estimate the effect size, and meta-regression was performed for variables with a likely influence on effect size. Subgroup analysis was performed based on the comparison used in the included studies.
RESULTS
Melatonin therapy in migraine was associated with a significantly higher responder rate when compared to both placebo and standard therapy (OR = 1.84; 95% CI: 1.08 to 3.14; P = .03). The results of the meta-analyses indicated that melatonin can achieve a significant reduction in frequency of migraine attacks (MD = 1.00; 95% CI: 0.02 to 1.98; P = .04), migraine attack duration (MD = 5.02; 95% CI: 0. 91 to 9.13; P = .02), use of analgesics (MD = 1.43; 95% CI: 0.38 to 2.48; P = .008), and migraine severity (MD = 1.93; 95% CI: 1.23 to 2.63; P < .0001) over placebo, but had no significant effects in comparison to amitriptyline or valproate. There was no significant difference in the occurrence of common adverse drug reactions, such as drowsiness and fatigue, between the melatonin group and the comparison groups.
CONCLUSIONS
Melatonin showed a beneficial prophylactic role in migraine, with a better responder rate in comparison to placebo in reducing migraine severity, mean attack duration, mean attack frequency, and analgesic use, but did not show significant effects in comparison to amitriptyline or valproate.

Meta-Analysis
BACKGROUND
Functional Abdominal Pain Disorders (FAPDs) present a considerable burden to paediatric patients, impacting quality of life, school attendance and causing higher rates of anxiety and depression disorders. There are no international guidelines for the management of this condition. A previous Cochrane Review in 2011 found no evidence to support the use of antidepressants in this context.
OBJECTIVES
To evaluate the current evidence for the efficacy and safety of antidepressants for FAPDs in children and adolescents.
SEARCH METHODS
In this updated review, we searched the Cochrane Library, PubMed, MEDLINE, Embase, PsycINFO and two clinical trial registers from inception until 03 February 2020. We also updated our search of databases of ongoing research, reference lists and 'grey literature' from inception to 03 February 2020.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) comparing antidepressants to placebo, to no treatment or to any other intervention, in children aged 4 to 18 years with a FAPD diagnosis as per the Rome or any other defined criteria (as defined by the authors). The primary outcomes of interest included treatment success (as defined by the authors), pain severity, pain frequency and withdrawal due to adverse events.
DATA COLLECTION AND ANALYSIS
Two review authors checked all citations independently, resolving disagreement with a third-party arbiter. We reviewed all potential studies in full text, and once again made independent decisions, with disagreements resolved by consensus. We conducted data extraction and 'Risk of bias' assessments independently, following Cochrane methods. Where homogeneous data were available, we performed meta-analysis using a random-effects model. We conducted GRADE analysis.
MAIN RESULTS
We found one new study in this updated search, making a total of three trials (223 participants) eligible for inclusion: two using amitriptyline (AMI) and one using citalopram. For the primary outcome of treatment success, two studies used reports of success on a symptom-based Likert scale, with either a two-point reduction or the two lowest levels defined as success. The third study defined success as a 15% improvement in quality of life (QOL) ratings scales. Therefore, meta-analysis did not include this final study due to the heterogeneity of the outcome measure. There is low-certainty evidence that there may be no difference when antidepressants are compared with placebo (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.87 to 1.56; 2 studies, 205 participants; I = 0%). We downgraded the evidence for significant imprecision due to extremely sparse data (see Summary of findings table 1). The third study reported that participants receiving antidepressants were significantly more likely than those receiving placebo to experience at least a 15% improvement in overall QOL score at 10 and 13 weeks (P = 0.007 and P = 0.002, respectively (absolute figures were not given)). The analysis found no difference in withdrawals due to adverse events between antidepressants and placebo: RR 3.17 (95% CI 0.65 to 15.33), with very low certainty due to high risk of bias in studies and imprecision due to low event and participant numbers. Sensitivity analysis using a fixed-effect model and analysing just for AMI found no change in this result. Due to heterogeneous and limited reporting, no further meta-analysis was possible.
AUTHORS' CONCLUSIONS
There may be no difference between antidepressants and placebo for treatment success of FAPDs in childhood. There may be no difference in withdrawals due to adverse events, but this is also of low certainty. There is currently no evidence to support clinical decision making regarding the use of these medications. Further studies must consider sample size, homogenous and relevant outcome measures and longer follow up.

There is no approved drug for fibromyalgia syndrome (FMS) in Europe. In the German S3 guideline, amitriptyline, duloxetine, and pregabalin are recommended for temporary use. The aim of this study was to cross-sectionally investigate the current practice of medication in FMS patients in Germany. We systematically interviewed 156 patients with FMS, while they were participating in a larger study. The patients had been stratified into subgroups with and without a decrease in intraepidermal nerve fiber density. The drugs most commonly used to treat FMS pain were nonsteroidal anti-inflammatory drugs (NSAIDs) (41.0% of all patients), metamizole (22.4%), and amitriptyline (12.8%). The most frequent analgesic treatment regimen was "on demand" (53.9%), during pain attacks, while 35.1% of the drugs were administered daily and the remaining in other regimens. Median pain relief as self-rated by the patients on a numerical rating scale (0-10) was 2 points for NSAIDS, 2 for metamizole, and 1 for amitriptyline. Drugs that were discontinued due to lack of efficacy rather than side effects were acetaminophen, flupirtine, and selective serotonin reuptake inhibitors. Reduction in pain severity was best achieved by NSAIDs and metamizole. Our hypothesis that a decrease in intraepidermal nerve fiber density might represent a neuropathic subtype of FMS, which would be associated with better effectiveness of drugs targeting neuropathic pain, could not be confirmed in this cohort. Many FMS patients take "on-demand" medication that is not in line with current guidelines. More randomized clinical trials are needed to assess drug effects in FMS subgroups.

We reported previously that increased acid sphingomyelinase (ASMase)-catalyzed hydrolysis of sphingomyelin, which leads to increases in ceramide and sphingosine 1 phosphate (S1P), played a key role in the synergistic upregulation of proinflammatory cytokines by palmitic acid (PA), a major saturated fatty acid, and lipopolysaccharide (LPS) in macrophages. Since macrophages are vital players in nonalcoholic steatohepatitis (NASH) and atherosclerosis, we assessed the effect of ASMase inhibition on NASH and atherosclerosis cooperatively induced by high-PA-containing high-fat diet (HP-HFD) and LPS in LDL receptor-deficient (LDLR-/-) mice. LDLR-/- mice were fed HP-HFD, injected with low dose of LPS and treated with or without the ASMase inhibitor amitriptyline. The neutral sphingomyelinase inhibitor GW4869 was used as control. Metabolic study showed that both amitriptyline and GW4869 reduced glucose, lipids, and insulin resistance. Histological analysis and Oil Red O staining showed that amitriptyline robustly reduced hepatic steatosis while GW4869 had modest effects. Interestingly, immunohistochemical study showed that amitriptyline, but not GW4869, strongly reduced hepatic inflammation. Furthermore, results showed that both amitriptyline and GW4869 attenuated atherosclerosis. To elucidate the underlying mechanisms whereby amitriptyline inhibited both NASH and atherosclerosis, but GW4869 only inhibited atherosclerosis, we found that amitriptyline, but not GW4869, downregulated proinflammatory cytokines in macrophages. Finally, we found that inhibition of sphingosine 1 phosphate production is a potential mechanism whereby amitriptyline inhibited proinflammatory cytokines. Collectively, this study showed that amitriptyline inhibited NASH and atherosclerosis through modulation of sphingolipid metabolism in LDLR-/- mice, indicating that sphingolipid metabolism in macrophages plays a crucial role in the linkage of NASH and atherosclerosis.

Poisoning is a significant cause of injury-related death worldwide. Dialysis is usually ineffective in removing the toxin once it has been absorbed because of drug protein binding and high volumes of distribution. In this work, we explore whether the addition of liposomes to peritoneal dialysate could extract protein bound amitriptyline. Liposomes were prepared using the thin film hydration method. In the in vitro experiment, 3 mL of 20% albumin with a concentration of 6000 nmol/L amitriptyline in a proprietary dialysis cartridge was dialysed against 125 mL of phosphate-buffered saline with and without 80 mg 1,2-dioleoyl-sn-glycero-3-phosphoglycerol (DOPG) liposomes. In the in vivo arm, peritoneal dialysis was undertaken in 6 rats with pH gradient liposome augmented dialysate after intravenous amitriptyline injection. Peritoneal blood flow was estimated by CO extraction. Total amitriptyline extracted was compared to freely dissolved (non-protein bound) and total amitriptyline perfusing the membrane during the peritoneal dwell. Mean liposome size for DOPG and acidic centre pH gradient liposomes was 119 nm and 430 nm, respectively. In the in vitro experiment, more amitriptyline was extracted into the liposome containing dialysate than the control dialysate (40 +/- 2 nmol/L vs. 27 +/- 1 nmol/L). In the in vivo experiment, the total amitriptyline in dialysate was 5240 +/- 2750 nmol. Mean total free amitriptyline perfusing the peritoneal membrane was 93 +/- 46 nmol. Mean total blood amitriptyline perfusing the peritoneal membrane was 23,920 +/- 6920 nmol. Two of the six animals were excluded due to overestimation of peritoneal blood flow. This exploratory work suggests the addition of liposome nanoparticles to peritoneal dialysate extracted protein bound amitriptyline from blood.

Meta-Analysis Review
BACKGROUND
Antidepressants are widely used to treat chronic neuropathic pain (pain due to nerve damage), usually in doses below those at which they exert antidepressant effects. An earlier review that included all antidepressants for neuropathic pain is being replaced by new reviews of individual drugs examining individual neuropathic pain conditions.Desipramine is a tricyclic antidepressant that is occasionally used for treating neuropathic pain.
OBJECTIVES
To assess the analgesic efficacy of desipramine for chronic neuropathic pain in adults, and to assess the associated adverse events.
SEARCH METHODS
We searched CENTRAL, MEDLINE, and EMBASE from inception to 29 April 2014, and the reference lists of retrieved papers and other reviews. We also used our own hand searched database to identify older studies, and two clinical trials databases for ongoing or unpublished studies.
SELECTION CRITERIA
We included randomised, double-blind studies of at least two weeks duration comparing desipramine with placebo or another active treatment in chronic neuropathic pain. Participants were adults aged 18 years and over. We included only full journal publication articles.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted the efficacy and adverse event data, and examined issues of study quality. We performed analysis using three tiers of evidence. First tier evidence was derived from data meeting current best standards and subject to minimal risk of bias (outcome equivalent to substantial pain intensity reduction, intention-to-treat analysis without imputation for dropouts, at least 200 participants in the comparison, 8 to 12 weeks duration, parallel design); second tier from data that failed to meet one or more of these criteria and were considered at some risk of bias but with adequate numbers in the comparison; and third tier from data involving small numbers of participants and considered very likely to be biased or that used outcomes of limited clinical utility, or both.
MAIN RESULTS
Five studies treated 177 participants with painful diabetic neuropathy (104) or postherpetic neuralgia (73). The mean or median ages in the studies were 55 to 72 years. Four studies used a cross-over, and one a parallel group design; 145 participants were randomised to receive desipramine 12.5 mg to 250 mg daily, with most taking 100 mg to 150 mg daily following titration. Comparators were placebo in three studies (an 'active placebo' in two studies), fluoxetine, clomipramine (one study each), and amitriptyline (two studies), and treatment was for two to six weeks. All studies had one or more sources of potential major bias.No study provided first or second tier evidence for any outcome. No data were available on the proportion of people with at least 50% or 30% reduction in pain, but data were available from three studies for our other primary outcome of Patient Global Impression of Change, reported as patient evaluation of pain relief that was 'complete' or 'a lot'. No pooling of data was possible, but third tier evidence in individual studies indicated some improvement in pain relief with desipramine compared with placebo, although this was very low quality evidence, derived mainly from group mean data and completer analyses in small, short duration studies where major bias was possible. There were too few participants in comparisons of desipramine with another active treatment to draw any conclusions.All studies reported some information about adverse events, but reporting was inconsistent and fragmented. Participants taking desipramine experienced more adverse events, and a higher rate of withdrawal due to adverse events, than did participants taking placebo (very low quality evidence).
AUTHORS' CONCLUSIONS
This review found little evidence to support the use of desipramine to treat neuropathic pain. There was very low quality evidence of benefit and harm, but this came from studies that were methodologically flawed and potentially subject to major bias. Effective medicines with much greater supportive evidence are available. There may be a role for desipramine in patients who have not obtained pain relief from other treatments.

Meta-Analysis
BACKGROUND
Half the US population uses drugs with anticholinergic properties. Their potential harms may outweigh their benefits. Amitriptyline is among the most frequently prescribed anticholinergic medicinal products, is used for multiple indications, and rated as strongly anticholinergic. Our objective was to explore and quantify (anticholinergic) adverse drug reactions (ADRs) in patients taking amitriptyline vs. placebo in randomized controlled trials (RCTs) involving adults and healthy individuals.
METHODS
We searched electronic databases from their inception until 09/2022, and clinical trial registries from their inception until 09/2022. We also performed manual reference searches. Two independent reviewers selected RCTs with ≥100 participants of ≥18 years, that compared amitriptyline (taken orally) versus placebo for all indications. No language restrictions were applied. One reviewer extracted study data, ADRs, and assessed study quality, which two others verified. The primary outcome was frequency of anticholinergic ADRs as a binary outcome (absolute number of patients with/without anticholinergic ADRs) in amitriptyline vs. placebo groups.
RESULTS
Twenty-three RCTs (mean dosage 5mg to 300mg amitriptyline/day) and 4217 patients (mean age 40.3 years) were included. The most frequently reported anticholinergic ADRs were dry mouth, drowsiness, somnolence, sedation, fatigue, constitutional, and unspecific anticholinergic ADRs. Random-effects meta-analyses showed anticholinergic ADRs had a higher odd's ratio for amitriptyline versus placebo (OR = 7.41; [95% CI, 4.54 to 12.12]). Non-anticholinergic ADRs were as frequent for amitriptyline as placebo. Meta-regression analysis showed anticholinergic ADRs were not dose-dependent.
DISCUSSION
The large OR in our analysis shows that ADRs indicative of anticholinergic activities can be attributed to amitriptyline. The low average age of participants in our study may limit the generalizability of the frequency of anticholinergic ADRs in older patients. A lack of dose-dependency may reflect limited reporting of the daily dosage when the ADRs occurred. The exclusion of small studies (<100 participants) decreased heterogeneity between studies, but may also have reduced our ability to detect rare events. Future studies should focus on older people, as they are more susceptible to anticholinergic ADRs.

INTRODUCTION
CYP2D6 and CYP2C19 functional status as defined by genotype is modulated by phenoconversion (PC) due to pharmacokinetic interactions. As of today, there is no data on the effect size of PC for CYP2C19 functional status. The primary aim of this study was to investigate the impact of PC on CYP2C19 functional status.
METHODS
Two patient cohorts (total n=316; 44.2±15.4 years) were investigated for the functional enzyme status of CYP2C19 applying two different correction methods (PC, PC) as well as serum concentration and metabolite-to-parent ratio of venlafaxine, amitriptyline, mirtazapine, sertraline, escitalopram, risperidone, and quetiapine.
RESULTS
There was a decrease in the number of normal metabolizers of CYP2C19 and an increase in the number of poor metabolizers. When controlled for age, sex, and, in the case of amitriptyline, venlafaxine, and risperidone, CYP2D6 functional enzyme status, an association was observed between the CYP2C19 phenotype/functional enzyme status and serum concentration of amitriptyline, sertraline, and escitalopram.
DISCUSSION
PC of CYP2C19 changes phenotypes but does not improve correlations with serum concentrations. However, only a limited number of patients received perturbators of CYP2C19. Studies with large numbers of patients are still lacking, and thus, it cannot be decided if there are minor differences and which method of correction to use. For the time being, PC is relevant in individual patients treated with CYP2C19-affecting drugs, for example, esomeprazole. To ensure adequate serum concentrations in these patients, this study suggests the use of therapeutic drug monitoring.
