Indeed, an increased abundance of Akkermansia in PD individuals is correlated with an increased presence of co-occurring opportunistic pathogens (Wallen et al., 2020), thereby supporting the notion that higher levels of typically less common microbial species represent a risk factor in modifying PD pathophysiology (Wallen et al., 2020)
A scoping review in Cureus (2025) added important context: dual-acting agonists like tirzepatide which targets both GLP-1 and GIP receptors produced greater reductions in weight and insulin sensitivity than GLP-1-only agents
Other relevant interactions: Colchicine (used for gout) may affect B12 absorption with long-term use Chloramphenicol (rarely used antibiotic) may blunt the haematological response to B12 treatment Monitoring considerations: Patients taking loop or thiazide diuretics require careful monitoring when initiating B12 therapy in severe deficiency, due to the risk of hypokalaemia during rapid cell production
