Name:
Schema Version:AIM-2.0
Interactions
Target id:
/condition/active-cancer
Target name:
Active Cancer
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
The role of Klotho in cancer is complex and not fully understood; it may act as a tumor suppressor or promoter depending on the cancer type and context.
Actionable advice:
Avoid completely in patients with a current diagnosis of cancer due to unpredictable and potentially harmful effects.
Target id:
/class/chemotherapy-radiation
Target name:
Cytotoxic Cancer Therapies (Chemotherapy & Radiation)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Klotho's cellular protective and anti-apoptotic mechanisms could theoretically interfere with the efficacy of therapies designed to kill rapidly dividing cancer cells.
Actionable advice:
Avoid completely during active cancer treatment to prevent reducing therapeutic efficacy.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
The effects of administering exogenous Klotho protein or gene therapy on fetal development are unknown and could be harmful.
Actionable advice:
Avoid completely during pregnancy due to unknown risks to the developing fetus.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
It is unknown if exogenous Klotho is excreted in breast milk or what its effects on a nursing infant would be.
Actionable advice:
Avoid completely while breastfeeding due to unknown risks to the infant.
Target id:
/intervention/calcitriol
Target name:
Active Vitamin D (Calcitriol)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Klotho's primary function is to suppress active Vitamin D (1,25-dihydroxyvitamin D) synthesis to control phosphate levels; administering active Vitamin D directly opposes this core mechanism.
Actionable advice:
Avoid co-administration as it directly counteracts Klotho's physiological function and can lead to mineral imbalances.
Target id:
/biomarker/serum-phosphate
Target name:
Serum Phosphate
Severity:
major
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
Klotho is a master regulator of phosphate homeostasis, primarily by increasing its excretion in the urine. Therapy requires monitoring to prevent hypophosphatemia or other imbalances.
Actionable advice:
Regularly monitor serum phosphate levels before and during Klotho therapy.
Target id:
/biomarker/serum-calcium
Target name:
Serum Calcium
Severity:
major
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
Klotho increases calcium reabsorption in the kidneys. Therapy requires monitoring to prevent hypercalcemia, especially if combined with other agents affecting calcium.
Actionable advice:
Regularly monitor serum calcium levels before and during Klotho therapy.
Target id:
/class/thiazide-diuretics
Target name:
Thiazide Diuretics
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Both Klotho and thiazide diuretics increase calcium reabsorption in the kidneys, which can lead to an additive effect and an increased risk of hypercalcemia (abnormally high calcium levels).
Actionable advice:
Use with caution and monitor serum calcium levels very closely if used together.
Target id:
/class/antidiabetic-medications
Target name:
Diabetes Medications
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Klotho has been shown to improve insulin sensitivity and glucose metabolism, which may potentiate the effects of glucose-lowering drugs and increase the risk of hypoglycemia.
Actionable advice:
Monitor blood glucose closely, especially upon initiation of Klotho, and be prepared to adjust medication doses.
Target id:
/class/anticholinergic-medications
Target name:
Anticholinergic Medications
Severity:
moderate
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
Anticholinergic drugs are known to impair cognitive function, which would directly oppose the potential pro-cognitive and neuroprotective benefits observed with Klotho in preclinical studies.
Actionable advice:
Avoid concurrent use of strong anticholinergic medications if cognitive enhancement is a goal.
Target id:
/dietary/high-phosphate-foods
Target name:
High-Phosphate Foods (Processed Foods, Sodas)
Severity:
moderate
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
A high dietary phosphate load places stress on the FGF23-Klotho system, counteracting the intended benefit of maintaining healthy phosphate balance.
Actionable advice:
Avoid foods with high phosphate additives (e.g., colas, processed meats and cheeses) to support Klotho's function.
Target id:
/condition/renal-impairment
Target name:
Renal Impairment
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
Klotho levels are naturally deficient in chronic kidney disease (CKD), and this deficiency contributes to the disease's progression. Klotho replacement is a potential therapeutic strategy for CKD.
Actionable advice:
Klotho therapy may be beneficial for this condition, but requires careful dose selection and monitoring by a specialist.
Target id:
/intervention/vitamin-k2
Target name:
Vitamin K2
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
Both Klotho and Vitamin K2 are critical for preventing vascular calcification, but they act through different pathways. Their combined action may offer superior cardiovascular protection.
Actionable advice:
Consider co-supplementation with Vitamin K2 for potentially enhanced cardiovascular benefits.
Target id:
/class/ghrps-ghrhs
Target name:
Growth Hormone Secretagogues
Severity:
moderate
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
Klotho signaling is known to suppress the growth hormone/IGF-1 axis, which is a proposed mechanism for its longevity effects. This action may counteract therapies designed to boost GH levels.
Actionable advice:
Be aware that Klotho may reduce the effectiveness of growth hormone-releasing peptides and hormones.
Target id:
/biomarker/igf-1
Target name:
Insulin-like Growth Factor 1
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
Because Klotho can suppress the GH/IGF-1 axis, monitoring IGF-1 levels can serve as a biomarker to assess the systemic biological activity of the therapy.
Actionable advice:
Periodically monitor IGF-1 levels to help gauge the systemic impact of Klotho therapy.
Target id:
/class/immunosuppressants
Target name:
Calcineurin Inhibitors
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
Calcineurin inhibitors like tacrolimus are nephrotoxic and are known to suppress endogenous Klotho expression. Exogenous Klotho may help mitigate this kidney damage.
Actionable advice:
Klotho may be renoprotective when using these drugs, but requires close monitoring of kidney function.
Target id:
/class/antihypertensives
Target name:
Antihypertensive Medications
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Klotho may promote vasodilation and have modest blood pressure-lowering effects, potentially increasing the risk of hypotension when combined with other blood pressure medications.
Actionable advice:
Monitor blood pressure, especially when initiating Klotho therapy or adjusting antihypertensive doses.
Target id:
/intervention/vitamin_d3_systemic_healthspan
Target name:
Vitamin D (High Dose)
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
High-dose Vitamin D supplementation increases calcium and phosphate absorption, which can work against Klotho's primary goal of maintaining mineral balance, potentially increasing hypercalcemia risk.
Actionable advice:
Use standard doses of Vitamin D and monitor serum calcium and phosphate levels if higher doses are required.
