Cystic fibrosis, hereditary hemochromatosis and palmar fibromatosis are often described as "Celtic", based on their contemporary prevalence. The former two are among genetically defined disorders that seem to provide survival advantages to heterozygote individuals, while severe health problems happen in homozygote mutation carriers. Although palmar fibromatosis has no defined mutations, its prevalence has been linked to the prevalence of Y-Chromosome Haplogroup I that expanded after the Last Ice Age, thus making th distribution of all three "Celtic" diseases dependent on the global climate from 40 to 8 Kya. During the Last Ice Age, the global climate was dry and dark due to dust-laden atmosphere (20-25 times more than today). It has been postulated that skin pigmentation was related to insolation, UV protection and skin synthesis of vitamin D, so when our ancestors moved to Eurasia, individuals with pale skin became advantageous. Deficiency of vitamin D has several health consequences and some of them have been proposed by other authors as important for the spreading of cystic fibrosis mutations: rickets/osteomalacia; susceptibility to diarrheal diseases and tuberculosis and salt induced arterial hypertension. The here proposed link is between vitamin D deficiency and the anaemia of chronic disease that might have facilitated spreading of the hemochromatosis mutation. It seems plausible that the risk of health problems in the offspring of close relatives might have resulted in social taboos of consanguinity in Eurasian protosocieties. Ancient steam bath rituals seem linked to lower incidences of cystic fibrosis in several European populations, thus suggesting health protection in an arid, dusty climate of the last glaciation, that made CFTR mutations in heterozygote carriers less advantageous.

Vitamin D deficiency is widespread worldwide and present in about 30-50% of population. In most cases, this problem is associated with musculoskeletal system pathology: rickets in children, and osteomalacia or osteoporosis in adults. However, in recent years, convincing data was obtained on the links between vitamin D deficiency and cardiovascular pathology. Low Vitamin D levels in humans are associated with the unfavorable cardiovascular risk factors, such as arterial hypertension (AH), diabetes mellitus, and dyslipidemia, which are the predictors of the severe cardiovascular diseases, including strokes and infarctions. It has been demonstrated that vitamin D has a strong vasoptotective effect via endothelial dysfunction improvement, prevents blood vessels and myocardium remodeling, improves blood pressure parameters, reduces the risk of development of left ventricular hypertrophy, slows down fibrosis, reduces the risk of atherosclerosis, reduces insulin resistance, and also affects inflammation and immunity. This article provides data of Russian and foreign studies demonstrating the effect of Vitamin D deficiency on the development of atherosclerosis, AH, heart rhythm disorder and progression of chronic heart failure.
