The aim of this meta-analysis is to explore the relationship between plasma total homocysteine (tHcy) levels, serum folic acid, vitamin B12 and vitamin B6 levels, methylenetetrahydrofolate reductase (MTHFR) C677T genotype and risk of pseudoexfoliation glaucoma (PEXG).
A systematic search of EMBASE and PubMed of relevant articles was carried out for all published articles. Main outcome measures included the calculation of plasma tHcy levels, serum folic acid, vitamin B12, and vitamin B6 levels mean difference and odds ratios (OR) of MTHFR C677T genotype between cases and controls.
There were 14 studies for tHcy (485 cases and 456 controls), five studies for folic acid (188 cases and 189 controls), six studies for vitamin B12 (199 cases and 225 controls), three studies for vitamin B6 (128 cases and 130 controls) and eight studies for MTHFR (479 cases and 661 controls). Overall, the mean plasma tHcy levels in cases was 3.38 umol/l (95% confidence intervals (CI): 2.35-4.42) higher than in controls. Serum folic acids, but not vitamin B12 and vitamin B6 levels, was significantly lower in cases than in controls; the weighted mean differences with 95% CI were -1.50 umol/l (-2.53, -0.46), -36.29 umol/l (-81.27, 8.68) and -0.60 umol/l (-2.55, 1.35) respectively. There was no evidence of association between the MTHFR C677T genotype and PEXG (OR = 1.28, 95%
PEXG is associated with elevated plasma tHcy and low serum folic acid levels, but not serum vitamin B12, vitamin B6 levels, and MTHFR C677T genotype.

Elevated serum homocysteine has been shown to be a risk factor for hypertension, cardiovascular disease (CVD), and type-2 diabetes mellitus (T2DM).We characterized the relationships between the serum ...
Type-2 Diabetes Mellitus (T2DM) and metformin both can lower serum B12 (s.B12). Raised serum Homocysteine (s.Hcy) is considered as an early marker of B12 deficiency.
Both lower serum 25-hydroxyvitamin D [25(OH)D] and elevated homocysteine concentrations are potential risk factors for cardiovascular disease (CVD). A recent analysis of the National Health and Nutrit...

Immune complex disease caused by the administration of foreign serum or serum proteins and characterized by fever, lymphadenopathy, arthralgia, and urticaria. When they are complexed to protein carriers, some drugs can also cause serum sickness when they act as haptens inducing antibody responses.
All blood proteins except albumin ( = SERUM ALBUMIN, which is not a globulin) and FIBRINOGEN (which is not in the serum). The serum globulins are subdivided into ALPHA-GLOBULINS; BETA-GLOBULINS; and GAMMA-GLOBULINS on the basis of their electrophoretic mobilities. (From Dorland, 28th ed)
The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.
An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
