Abstract
This analysis critically examines the profit-driven marketing of digestive enzymes as over-the-counter (OTC) supplements in the context of India, expressing ethical concerns regarding pharmaceutical companies prioritizing financial gain over genuine public health needs within the lucrative OTC supplement market. The review delves into various enzymes, their mechanisms of action, uses, adverse drug reactions, and provides evidence from various studies. The research method involves the exploration of profit-driven strategies employed by pharmaceutical companies, addressing regulatory challenges, investigating the gap between dietary supplements and pharmaceutical drugs, and emphasizing the impact of direct-to-consumer advertising on self-diagnosis and overuse. Additionally, the study reviews various e-pharmacy platforms in India, assessing formulations and pricing. Key findings highlight the diverse formulations on these platforms, exposing insights into cost variations and indicating a regulatory gap that necessitates a comprehensive re-evaluation by Indian and international authorities. The analysis emphasizes the influence of direct-to-consumer advertising on behavior and potential health risks, raising ethical concerns about oversimplified health claims that overlook the necessity for individualized treatment plans. In conclusion, the study underscores the ethical complexity of prioritizing profit over public health and advocates for regulatory re-evaluation, exploring broader implications such as cultural influences and alternative therapies. The evolving landscape, featuring plant-based and microbe-derived alternatives, is presented as transformative, particularly in conditions like celiac disease.

Functional variants in the sucrase-isomaltase gene associate with increased risk of irritable bowel syndrome. Gut 2018; 67:263-270. [PMID: 27872184 PMCID: PMC5563477 DOI: 10.1136/gutjnl-2016-312456] [Citation(s) in RCA: 109] [Impact Index Per Article: 18.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2016] [Revised: 10/29/2016] [Accepted: 10/31/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVE IBS is a common gut disorder of uncertain pathogenesis. Among other factors, genetics and certain foods are proposed to contribute. Congenital sucrase-isomaltase deficiency (CSID) is a rare genetic form of disaccharide malabsorption characterised by diarrhoea, abdominal pain and bloating, which are features common to IBS. We tested sucrase-isomaltase (SI) gene variants for their potential relevance in IBS. DESIGN We sequenced SI exons in seven familial cases, and screened four CSID mutations (p.Val557Gly, p.Gly1073Asp, p.Arg1124Ter and p.Phe1745Cys) and a common SI coding polymorphism (p.Val15Phe) in a multicentre cohort of 1887 cases and controls. We studied the effect of the 15Val to 15Phe substitution on SI function in vitro. We analysed p.Val15Phe genotype in relation to IBS status, stool frequency and faecal microbiota composition in 250 individuals from the general population. RESULTS CSID mutations were more common in patients than asymptomatic controls (p=0.074; OR=1.84) and Exome Aggregation Consortium reference sequenced individuals (p=0.020; OR=1.57). 15Phe was detected in 6/7 sequenced familial cases, and increased IBS risk in case-control and population-based cohorts, with best evidence for diarrhoea phenotypes (combined p=0.00012; OR=1.36). In the population-based sample, 15Phe allele dosage correlated with stool frequency (p=0.026) and Parabacteroides faecal microbiota abundance (p=0.0024). The SI protein with 15Phe exhibited 35% reduced enzymatic activity in vitro compared with 15Val (p<0.05). CONCLUSIONS SI gene variants coding for disaccharidases with defective or reduced enzymatic activity predispose to IBS. This may help the identification of individuals at risk, and contribute to personalising treatment options in a subset of patients.
