Effects of sodium citrate, citric acid and lactic acid on human blood coagulation
Perfusion 2018 Oct;33(7):577-583.PMID:29783879DOI:10.1177/0267659118777441.
Introduction: Citric acid infusion in extracorporeal blood may allow concurrent regional anticoagulation and enhancement of extracorporeal CO2 removal. Effects of citric acid on human blood thromboelastography and aggregometry have never been tested before. Methods: In this in vitro study, citric acid, sodium citrate and lactic acid were added to venous blood from seven healthy donors, obtaining concentrations of 9 mEq/L, 12 mEq/L and 15 mEq/L. We measured gas analyses, ionized calcium (iCa++) concentration, activated clotting time (ACT), thromboelastography and multiplate aggregometry. Repeated measure analysis of variance was used to compare the acidifying and anticoagulant properties of the three compounds. Results: Sodium citrate did not affect the blood gas analysis. Increasing doses of citric and lactic acid progressively reduced pH and HCO3- and increased pCO2 (p<0.001). Sodium citrate and citric acid similarly reduced iCa++, from 0.39 (0.36-0.39) and 0.35 (0.33-0.36) mmol/L, respectively, at 9 mEq/L to 0.20 (0.20-0.21) and 0.21 (0.20-0.23) mmol/L at 15 mEq/L (p<0.001). Lactic acid did not affect iCa++ (p=0.07). Sodium citrate and citric acid similarly incremented the ACT, from 234 (208-296) and 202 (178-238) sec, respectively, at 9 mEq/L, to >600 sec at 15 mEq/L (p<0.001). Lactic acid did not affect the ACT values (p=0.486). Sodium citrate and citric acid similarly incremented R-time and reduced α-angle and maximum amplitude (MA) (p<0.001), leading to flat-line thromboelastograms at 15 mEq/L. Platelet aggregometry was not altered by any of the three compounds. Conclusions: Citric acid infusions determine acidification and anticoagulation of blood similar to lactic acid and sodium citrate, respectively.
Extracellular citrate and metabolic adaptations of cancer cells
Cancer Metastasis Rev 2021 Dec;40(4):1073-1091.PMID:34932167DOI:10.1007/s10555-021-10007-1.
It is well established that cancer cells acquire energy via the Warburg effect and oxidative phosphorylation. citrate is considered to play a crucial role in cancer metabolism by virtue of its production in the reverse Krebs cycle from glutamine. Here, we review the evidence that extracellular citrate is one of the key metabolites of the metabolic pathways present in cancer cells. We review the different mechanisms by which pathways involved in keeping redox balance respond to the need of intracellular citrate synthesis under different extracellular metabolic conditions. In this context, we further discuss the hypothesis that extracellular citrate plays a role in switching between oxidative phosphorylation and the Warburg effect while citrate uptake enhances metastatic activities and therapy resistance. We also present the possibility that organs rich in citrate such as the liver, brain and bones might form a perfect niche for the secondary tumour growth and improve survival of colonising cancer cells. Consistently, metabolic support provided by cancer-associated and senescent cells is also discussed. Finally, we highlight evidence on the role of citrate on immune cells and its potential to modulate the biological functions of pro- and anti-tumour immune cells in the tumour microenvironment. Collectively, we review intriguing evidence supporting the potential role of extracellular citrate in the regulation of the overall cancer metabolism and metastatic activity.
citrate chemistry and biology for biomaterials design
Biomaterials 2018 Sep;178:383-400.PMID:29759730DOI:10.1016/j.biomaterials.2018.05.003.
Leveraging the multifunctional nature of citrate in chemistry and inspired by its important role in biological tissues, a class of highly versatile and functional citrate-based materials (CBBs) has been developed via facile and cost-effective polycondensation. CBBs exhibiting tunable mechanical properties and degradation rates, together with excellent biocompatibility and processability, have been successfully applied in vitro and in vivo for applications ranging from soft to hard tissue regeneration, as well as for nanomedicine designs. We summarize in the review, chemistry considerations for CBBs design to tune polymer properties and to introduce functionality with a focus on the most recent advances, biological functions of citrate in native tissues with the new notion of degradation products as cell modulator highlighted, and the applications of CBBs in wound healing, nanomedicine, orthopedic, cardiovascular, nerve and bladder tissue engineering. Given the expansive evidence for citrate's potential in biology and biomaterial science outlined in this review, it is expected that citrate based materials will continue to play an important role in regenerative engineering.
citrate tolerance
Calif Med 1950 Dec;73(6):494-6.PMID:14792339doi
There is a wide variation among human beings in tolerance to sodium citrate. It is important to those concerned with blood transfusions that the incidence of reactions to citrate is quite low, except in the event of massive transfusing, when the amount of citrate with the blood being given to the patient must be carefully considered.
[Regional citrate anticoagulation for continuous renal replacement therapy]
Rev Med Suisse 2020 Oct 21;16(711):2002-2006.PMID:33085257doi
Regional citrate anticoagulation (RCA) is currently the recommended anticoagulation modality for continuous renal replacement therapy. Indeed, compared with systemic heparinization, RCA is associated with a lower risk of bleeding, a longer circuit lifespan and a decrease nursing workload. However, RCA requires a strict protocol to be followed, as it might be associated with potentially severe complications, such as citrate accumulation. citrate accumulation is rare and usually associated with specific situations : severe circulatory shock, liver failure and mitochondrial dysfunction. According to centers' expertise, these situations might represent contra-indications to RCA. This review presents RCA, its mode of action, associated risks and proposes an algorithm for patients' selection.
