The disease map

Disease moduleLactose intolerance maps to a 2-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for lactose intolerance is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

What the evidence adds up to

A 2010 systematic review of 26 primary diagnostic studies found that the diagnostic performance of diarrhoea, abdominal pain, bloating, flatulence and self-reported milk intolerance was highly variable. Both people who malabsorb lactose and those who absorb it normally reported symptoms during the lactose hydrogen breath test. The review concluded that high-quality studies on diagnosis in primary care are urgently needed and that the concept of lactose intolerance itself requires a clear definition and a standardised assessment method.

Lactose intolerance cannot be cured. Management depends on the type of hypolactasia, the severity of symptoms, and the patient's age. The basic approach involves reducing the lactose content of food, using lactose-reduced milk and milk products, and taking over-the-counter lactase enzyme supplements or lactose-depleted products. Patients on a lactose-free diet should consult a nutrition counsellor to prevent deficiencies, particularly of calcium, which can lead to serious medical problems. Iatrogenic lactose intolerance can develop after certain drugs, gastric surgery, or ionising radiation.

A 2012 chapter notes that lactose intolerance is a real clinical syndrome but is not as prevalent as older literature suggested. Individuals with real or perceived intolerance may inappropriately restrict dairy foods, increasing their risk for preventable diseases. Recent data cited in that chapter show adverse health consequences associated with dairy avoidance and improvement in health outcome parameters with consistent consumption of a dairy-rich diet. The majority of the world's population with Asian or African origins is lactose intolerant.

What is still missing is a standardised definition of lactose intolerance and validated diagnostic tools for primary care, where most patients first present. No randomised controlled trials compare long-term outcomes of different management strategies, and no studies stratify patients by severity of lactase deficiency or by the specific symptoms that bother them most. Funding for such trials, rather than for further descriptive work, would be needed to move beyond dietary advice and enzyme supplements.

Lactose malabsorption and intolerance: a systematic review on the diagnostic value of gastrointestinal symptoms and self-reported milk intolerance

AbstractBACKGROUND: When lactose malabsorption gives rise to symptoms, the result is called 'lactose intolerance'. Although lactose intolerance is often bothersome for patients, once recognized it may be managed by simple dietary adjustments. However, diagnosing lactose intolerance is not straightforward, especially in primary care. AIM: To summarize available evidence on the diagnostic performance of gastrointestinal symptoms and self-reported milk (lactose) intolerance in primary care, and the relationship between lactose malabsorption and intolerance. DATA SOURCES: PubMed, EMBASE and reference screening. STUDY SELECTION: Studies were selected if the design was a primary diagnostic study; the patients were adults consulting because of non-acute abdominal symptoms; the diagnostic test included gastrointestinal symptoms and/or self-reported milk intolerance. A total of 26 primary diagnostic studies were included in the review. DATA EXTRACTION: Quality assessment and data extraction were performed by two reviewers independently. They adhered to the most recent guidelines for conducting a diagnostic review as described in the Cochrane Diagnostic Reviewers' Handbook. RESULTS: The diagnostic performance of diarrhea, abdominal pain, bloating, flatulence and self-reported milk intolerance was highly variable. A non-Caucasian ethnic origin was associated with the presence of lactose malabsorption. Both lactose malabsorbers and lactose absorbers reported symptoms during the lactose hydrogen breath test. CONCLUSION: Our review shows that high-quality studies on the diagnosis of lactose malabsorption and intolerance in primary care are urgently needed. An important prerequisite would be to clearly define the concept of lactose intolerance, as well as how it should be assessed.

Management of Lactose Intolerance

AbstractThe management of lactose intolerance comprises two parts: (1) the basic principles of treatment in persons intolerant to a dietary dose of lactose, and (2) main manoeuvres to reduce the lactose content in food, and/or consumption of special products of milk or exogenous lactase enzyme. The tactics of management depend on the type of hypolactasia, the severity of intolerance, and on the age of the patient. Special attention is paid to the development of lactose intolerance in some patients via iatrogenic mechanisms such as certain drugs, gastric surgery and ionizing radiation.

ADULT-TYPE LACTASE DEFICIENCY

AbstractLactose intolerance refers to gastrointestinal symptoms such as diarrhea and abdominal cramps after ingesting a known quantity of milk or milk-containing products. The nutrition counselor is in an ideal position to help patients understand how to control their gastrointestinal symptoms by selecting appropriate foods. Patients can minimize their gastrointestinal symptoms by reading food labels, identifying foods that contain lactose, and using moderation to avoid symptoms, preparing low-lactosecontaining foods, and using lactase preparations when necessary. Patients who are on a lactose-free diet should consult with a nutrition counselor to prevent nutritional deficiencies (eg, calcium) that can lead to serious medical problems.

Lactose Intolerance

AbstractIntolerance to lactose-containing foods is not so uncommon. Clinical symptoms of lactose intolerance in children include abdominal pain, flatulence, and diarrhea after ingesting milk or milk-containing products. These symptoms have been attributed to lactose malabsorption, which results from low levels of small intestinal lactase. Reduced lactase level may be due to mucosal injury or, much more commonly, reduced genetic expression of the enzyme lactase-phlorizin hydrolase. However, lactose intolerance cannot be cured. Still, it can be adequately managed by using lactose-reduced milk and milk products and over-the-counter supplements of lactase, lactose-depleted products, and other essential milk nutrients such as calcium. This article will review the clinical manifestations, diagnosis, and management of lactose intolerance in children.

Lactose Intolerance: What Consumers Need to Know

AbstractLactose intolerance is a condition that occurs when people cannot effectively digest lactose. Lactose intolerance is often related to our age and genetic origin and the majority of the world’s population with Asian or African origins is lactose intolerant.Managing lactose intolerance and malabsorption depends on the intensity and severity of symptoms. Treatments include reducing or eliminating lactose-containing foods (dairy), replacing lactose-containing foods with other foods containing similar nutrients, and using lactase supplements or similar products. This publication will provide information and guidance for consumers so that they may find the right information for their situation.

CHAPTER 48. Lactose Intolerance and the Consumption of Dairy Foods

AbstractLactose intolerance is a real clinical syndrome that occurs when there is symptomatic lactose maldigestion due to lactase non-persistence, but is not as prevalent as previously suggested by older literature. Individuals with real or perceived intolerance may inappropriately restrict dairy foods in the diet increasing their risk for preventable diseases. Recent data demonstrate that there are adverse health consequences associated with dairy avoidance and show improvement in health outcome parameters with consistent consumption of a dairy rich diet. This chapter will define the clinical syndrome of lactose intolerance, outline the health implications of dairy food avoidance, and describe specific strategies to manage lactose intolerance.
