Homocystinuria, a rare inherited disturbance of amino acid metabolism is associated with severe atherosclerosis and thromboembolism already in childhood. The incidence of the homozygous disease of cystathionine beta synthase is estimated to be 1:200,000, that of the heterozygous form 1:300. There are, however, numerous other causes of a mild to moderate homocysteinemia, for example, a deficiency of the cofactors vitamin B6, B12 and folic acid. The question as to whether a mild to moderate elevation of homocysteine in the plasma is also associated with an increased risk of CAD has been investigated in a number of studies in recent years. In summary, however, the presently available data do not provide a basis of proof that a mild to moderate homocysteinemia is an independent risk factor for CAD. Our present knowledge suggests that only when the family history is clearly positive does it appear reasonable to undertake a diagnostic search for possible homocysteinemia.

The aim of this study was to study the relationship between plasma homocysteine (Hcy), folic acid, vitamin B12 and early coronary artery disease (early-CAD) and high coronary risk factors. The plasma Hcy levels of 58 cases with early-CAD and 31 subjects without CAD were measured using high-performance liquid chromatography (HPLC) with fluorescence detection. Plasma folic acid and Vitamin B12 levels were measured with radioassay method. The plasma Hcy level was significantly higher in the early-CAD patients than in the controls [(13.7 +/- 5.1) micromol/L vs (10.3 +/- 5.7) micromol/L]. The plasma folic acid and Vitamin B12 levels were significantly lower in the early-CAD patients than in the controls. The plasma Hcy level was higher in patients with more than 3 risk factors of CAD than in patients with 1 or 2 risk factors and in the controls [(17.3 +/- 5.1) micromol/ L vs (12.9 +/- 4.8) micromol/L, (7.8 +/- 2.5) micromol/L]. Other than gender, all classical coronary risk factors were related to the elevated Hcy level. Hcy levels were elevated in patients with early-CAD and with high risk factors. Hyperhomocysteinemia plays an important role in the pathogenesis of CAD.

Premature graying of hair (PGH) being a very common entity for which pharmacotherapy and reversibility are not properly addressed. Therefore, this systematic review was conducted to address these issues. For this relevant study were selected from various databases including PubMed, EMBASE, OVID, Web of science, Scopus, and Google Scholar till January 20, 2019. Studies which reported risk factors, co-morbid conditions associated with PGH, its pharmacotherapy and reversal were included in the study. Although many risk factors are reported in literature, smoking, vitamin deficiency (B12, folic acid, and B7), mineral deficiency (low serum calcium and serum ferritin) are found to be associated with PGH. Other important risk factors are family history of PGH, obesity, high B.P, lack of exercise, drugs, genetic syndromes, dyslipidemia, thyroid disorders, hyperuricemia, and alteration in liver function. PGH is found to be an important marker of CAD, more so in case of smoker. Among different pharmacotherapeutic management options, low grade recommendation (2A) is given to calcium pantothenate, PABA, calcium pantothenate + PABA combination. Anu-tailam is the only herbal agent evaluated in clinical research settings. Finally, treating the accompanying pathologies led to the reversal of the disease in many cases.
