To offer a broad perspective on small bowel neuroendocrine tumors (NETs), this review details their clinical presentation, diagnostic pathways, and management considerations. We also display the newest information on management approaches, and propose potential fields for future investigation.
Compared to an Octreotide scan, a DOTATATE scan exhibits improved sensitivity in identifying neuroendocrine tumors. Small bowel endoscopy, a procedure providing a complementary perspective to imaging, allows for mucosal visualization and the precise definition of small lesions that would otherwise remain undetectable on imaging. The best management approach, even in cases of metastatic disease, remains surgical resection. Somatostatin analogues and Evarolimus, when used as a second-line treatment strategy, can favorably impact prognosis.
Lesions, either single or multiple, of a heterogeneous nature, frequently affect the distal small intestine, constituting NETs. Secretary behavior can lead to a variety of symptoms, including diarrhea and weight loss, as the most common Carcinoid syndrome and liver metastases are frequently found together.
Multiple or single lesions of NETs, a heterogeneous tumor type, often occur in the distal small bowel. The secretary's behavior is a potential trigger for conditions, most notably diarrhea and a reduction in weight. Carcinoid syndrome is frequently accompanied by the presence of liver metastases.
The diagnosis of celiac disease has, for the last seventy years, been significantly reliant on duodenal biopsies. Recent pediatric guidelines have diminished the significance of duodenal biopsies, introducing a non-biopsy approach into the diagnostic process. This review, focusing on adult coeliac disease, explores the no-biopsy method, specifically highlighting the advancements in non-biopsy diagnostic techniques.
Data indicates that a non-invasive approach to diagnosing adult celiac disease is accurate. Yet, a considerable number of circumstances remain that promote duodenal biopsy for a specific subset of patients. Furthermore, diverse factors need to be assessed should this trajectory be implemented into local gastroenterological care.
For an accurate diagnosis of adult coeliac disease, duodenal biopsies are still a vital procedure. An alternative approach, eliminating the requirement for biopsies, could be an option for specific adult cases. To ensure the proper implementation of this path within future guidelines, efforts should concentrate on promoting an effective dialogue between primary and secondary care systems.
Adult celiac disease diagnosis frequently includes duodenal biopsies as a crucial step. see more Nevertheless, a prospective approach, not demanding biopsies, could be an option for chosen adult patients. For the proper execution of this method, future guidelines including this pathway must focus on facilitating discussion between primary and secondary care facilities.
A looser stool consistency, coupled with increased stool frequency and urgency, are hallmarks of bile acid diarrhea, a prevalent yet under-recognized gastrointestinal disorder. see more This review summarizes recent progress in the pathophysiology, mechanisms, clinical presentation, diagnosis, and treatment of BAD.
A common feature of BAD in patients is accelerated colonic transit, amplified gut mucosal permeability, a changed stool microbiome, and a decreased quality of life. see more Stool tests for bile acids, either by themselves or alongside fasting serum 7-alpha-hydroxy-4-cholesten-3-one levels, exhibit strong diagnostic ability for BAD, demonstrating a good balance between sensitivity and specificity. Novel therapeutic approaches are augmented by the inclusion of farnesoid X receptor agonists and glucagon-like peptide 1 agonists.
Recent studies have provided greater clarity on the pathophysiology and mechanisms of BAD, opening up possibilities for more targeted treatment approaches for BAD. Diagnostic methods, newer, more affordable, and easier, enable the diagnosis of BAD.
Thanks to recent research, there's a growing appreciation for the pathophysiology and mechanisms of BAD, potentially opening doors for more targeted therapeutic interventions for BAD. Improved diagnostic methods, which are both more affordable and simpler to execute, enable the diagnosis of BAD more easily.
Artificial intelligence (AI) methodologies, applied to extensive data collections, have garnered significant interest in the recent past, enabling evaluation of disease prevalence, treatment protocols, and patient prognoses. To summarize the present utilization of AI in contemporary hepatology practice is the intent of this review.
AI demonstrated diagnostic value in evaluating liver fibrosis, detecting cirrhosis, differentiating compensated and decompensated cirrhosis, assessing portal hypertension, identifying and classifying liver masses, pre-operative evaluation of hepatocellular carcinoma, tracking treatment response, and estimating graft survival in liver transplant patients. AI presents a promising avenue for examining structured electronic health records, and equally for analyzing clinical text using various natural language processing techniques. AI's accomplishments notwithstanding, inherent limitations exist, stemming from the quality of the underlying data, small, potentially biased sample groups, and the absence of robust, readily replicable models.
The extensive applicability of AI and deep learning models is key to assessing liver disease. Still, multicenter randomized controlled trials are indispensable for confirming their practical value in various settings.
In the evaluation of liver disease, deep learning models, augmented by AI, show extensive applicability. The utility of these methods depends, however, on multicenter randomized controlled trials for validation.
Alpha-1 antitrypsin deficiency, a genetic disorder with a high prevalence, is a consequence of mutations in the alpha-1 antitrypsin gene, impacting predominantly the respiratory system and liver. The review covers the pathophysiological mechanisms and clinical outcomes of distinct AATD genotypes and explores the current therapeutic innovations. The uncommon, homozygous PiZZ, and the widely observed heterozygous PiMZ genotype represent the core of the current study.
The presence of the PiZZ gene variant is associated with a significantly elevated risk of liver fibrosis and cirrhosis, potentially up to 20 times higher than in individuals lacking this variant; liver transplantation presently constitutes the sole available treatment. The proteotoxic disorder AATD, stemming from excessive hepatic AAT accumulation, is currently being investigated with considerable promise, particularly through a phase 2, open-label trial utilizing the hepatocyte-targeted siRNA, fazirsiran. Subjects with the PiMZ genetic marker demonstrate an elevated risk of progressing to advanced liver disease, experiencing a more accelerated deterioration in later stages than those lacking the AAT mutation.
Although the fazirsiran data provides a ray of hope for AATD patients, a unified approach to defining the best study outcomes, a strategic approach to patient selection, and rigorous monitoring of long-term safety are critical for approval
The fazirsiran data, while promising for AATD patients, demand consensus on a suitable study endpoint, stringent patient selection procedures, and robust long-term safety monitoring protocols to merit approval.
Individuals with a normal body mass index (BMI) can also develop nonalcoholic fatty liver disease (NAFLD), experiencing the hepatic inflammation, fibrosis, and decompensated cirrhosis indicative of disease progression, similar to those with obesity. The clinical procedure of evaluating and treating NAFLD in this specific patient population presents difficulties for the gastroenterologist. The understanding of NAFLD's prevalence, progression, and results in individuals with a normal body mass index is progressing. Clinical characteristics of NAFLD in normal-weight subjects, in relation to metabolic dysfunction, are the focus of this review.
Notwithstanding a more favorable metabolic composition, patients with normal weight and NAFLD demonstrate metabolic dysfunction. In normal-weight individuals, the presence of visceral fat may be a key factor in developing NAFLD, while waist circumference might prove a superior indicator of metabolic risk compared to BMI. While NAFLD screening isn't currently part of standard practice, new guidelines offer support for clinicians in the assessment, categorization, and treatment of NAFLD in individuals with a normal BMI.
Individuals with a healthy BMI often acquire NAFLD due to a range of causative agents. A key factor in NAFLD for these patients might be subclinical metabolic dysfunction, and a more detailed understanding of this association within this patient group is necessary.
A normal BMI frequently precedes the acquisition of NAFLD, owing to diverse etiological factors. Within this patient population, subclinical metabolic dysfunction might be intrinsically related to NAFLD, thus highlighting the importance of further research to investigate this correlation.
In the United States, the most common cause of liver disease, nonalcoholic fatty liver disease (NAFLD), possesses a substantial hereditary component. A deeper comprehension of NAFLD's genetic foundations has yielded crucial insights into its disease progression, potential treatment avenues, and predictive indicators. This review aggregates data on both common and rare genetic variants linked to NAFLD, combining risk variants into polygenic scores to forecast NAFLD and cirrhosis, and scrutinizes the promising emerging evidence of gene silencing as a potential therapeutic target.
Variants in HSD17B13, MARC1, and CIDEB have been found to offer protection against cirrhosis, with a 10-50% lower risk observed. The convergence of NAFLD risk variants, such as those situated within the PNPLA3 and TM6SF2 genes, alongside these factors, permits the formulation of polygenic risk scores that correlate with liver fat deposition, cirrhosis progression, and the likelihood of hepatocellular carcinoma.
