AI Article Synopsis
- The study examines the relationship between folate and vitamin B12 deficiencies and hyperhomocysteinemia in young patients (ages 15-30) with psychotic disorders, suggesting these issues may be linked to schizophrenia.
- Out of 334 patients, 56% had relevant data available, and 32% showed abnormalities in one-carbon metabolism, with folate deficiency being the most common.
- The findings indicate that these metabolic issues are prevalent in first-episode psychosis and suggest that strategies like folate supplementation could be beneficial for personalized treatment.
Article Abstract
Introduction: Folates, the main actors in one-carbon (C1) metabolism, are involved in synthesising monoamines and maintaining genomic stability. Previous studies support the association between C1 metabolism and schizophrenia. The main purpose of this study was to assess the prevalence of plasma folate, and/or vitamin B12 deficiencies and hyperhomocysteinemia in young patients with psychotic disorders.
Methods: We included young inpatients (15-30 years old) with psychosis between 2014 and 2017 from Sainte-Anne Hospital in Paris. Plasma folate, vitamin B12 deficiency and homocysteinemia dosages were done at admission. Clinical data were extracted retrospectively, and patients diagnosed with a first-episode psychosis (FEP), schizophrenia, schizoaffective disorder, or persistent delusional disorder were retained for the analysis.
Results: Among the 334 inpatients, 188 (56%) had C1 dosages available (135 males; 53 females). From the 188 patients, 32% had a C1 abnormality. This abnormality reached 38% of FEP patients. The most frequent abnormality was folate deficiency: 21% of all patients and 27% of FEP. Lower levels of folates were found in males compared to females ( = 0.02) and were correlated with more severe disorder, as assessed by Clinical Global Impression - Severity (CGI-S; = 0.009). Antipsychotic dosage was positively associated with B12 levels ( = 0.013) and negatively with homocysteinemia ( = 0.034).
Conclusion: One-carbon metabolism anomalies in young patients with psychotic disorders are highly prevalent, reaching almost half of the patients with FEP. Potential protective effects from females and antipsychotics have emerged. These results spotlight the need for new therapeutic prospects, such as folate supplementation, to achieve personalised medical approaches to the early stages of psychotic disorders.

Folates comprise a crucial class of biologically active compounds related to folic acid, playing a vital role in numerous enzymatic reactions. One-carbon metabolism, facilitated by the folate cofactor, supports numerous physiological processes, including biosynthesis, amino acid homeostasis, epigenetic maintenance, and redox defense. Folates share a common pterin heterocyclic ring structure capable of undergoing redox reactions and existing in various protonation states.

Demands for animal products are projected to increase in the future, and animal production is key to agricultural sustainability and food security; consequently, enhancing ruminant livestock production efficiencies in sustainable ways is a major goal for the livestock industry. Developmental programming is the concept that various stressors, including compromised maternal nutrition during critical developmental windows will result in both short- and long-term changes in the offspring. Ruminant models of developmental programming indicate that compromised maternal nutrition, including global under and over-nutrition, macronutrients, and specific micronutrients, including amino acids (Met and Arg), vitamins (folate, B, and choline), and minerals (sulfur, cobalt, and selenium) can alter offspring outcomes.

The developmental integrity and wellbeing of offspring are influenced by events that occur in utero, particularly around the time of conception. While extraneous factors such as environmental temperature and exposure to environmental chemicals can each have a bearing on these events, the epigenetic mechanisms that direct cellular differentiation during early development in ruminants are best described for studies which have investigated the effects of parental nutrition or pregnancy outcomes following assisted reproduction. In this article the case is made that the genetic constitution of an individual directs epigenetic responses to environmental stimuli, and consideration in this regard is also given to the origins of sexual dimorphism and mechanisms of germline intergenerational inheritance.

Methane (CH) emission from livestock feces, led by ruminants, shows a profound impact on global warming. Despite this, we have almost no information on the syntrophy of the intact microbiome metabolisms, from carbohydrates to the one-carbon units, covering multiple stages of ruminant development. In this study, syntrophic effects of polysaccharide degradation and acetate-producing bacteria, and methanogenic archaea were revealed through metagenome-assembled genomes from water saturated dairy cattle feces.
