Latent toxoplasmosis and vitamin D concentration in humans: three observational studies

Numerous recent studies show that vitamin D deficiency potentiates various chronic physical and psychiatric disorders diseases. It has been shown a similar range of is also associated with latent infection Toxoplasma gondii (Nicolle et Manceaux, 1908). For instance, among cancer, diabetes schizophrenia patients, we find higher prevalence both toxoplasmosis deficiency. Theoretically, therefore, could be the missing link between these disorders. We tested this hypothesis by searching for decreased levels in serum subjects infected T. (furthermore called Toxoplasma-infected subjects) two cross-sectional one case-control study. Results first study (N = 72) suggest neurasthenic patients have non-significantly lower calcidiol than Toxoplasma-free (study A: P 0.26 women, 0.68 men). However, other B: N 400; C: 191) showed concentration men 0.70, 0.55) women 0.64, 0.12). Taken together, our preliminary results thus do not support decrease.
