BACKGROUND: Individuals with Parkinson's disease (PD) have decreased glutathione levels and elevated homocysteine levels. These substances are considered markers of health, and an inverse relationship has been suggested through the transsulfuration pathway. This experiment tested the effects of exercise and B vitamin supplementation on homocysteine and glutathione levels, and if a relationship was present between these two markers in those with PD. Secondary aims included examining the impact of the interventions on aerobic efficiency and strength...

Hyperhomocysteinemia is associated with an increased risk of Alzheimer's disease (AD). Our previous work has demonstrated that combined folate and vitamin B12 (vit-B12) supplementation prevents tau hyperphosphorylation and memory deficits induced by acute administration of homocysteine in young rats. Here, we further investigated whether folate/vit-B12 supplementation is also effective in aged rats with a chronically high level of homocysteine. 18-month-old rats were injected with homocysteine via the vena caudalis with or without a concurrent folate/vit-B12 supplementation for 28 weeks...

Monitoring of adverse drug reactions of a drug is a continuous process and runs through-out the life of a drug. Many rare adverse effects of a drug are documented after years of use; when a single case (signal generation) is reported leading subsequently to reporting of more cases. Deficiency of Vitamin B12 (vit B(12)) is a known sequel of prolonged metformin therapy. It was recommended to have annual measurement of serum vit B(12) levels in patients on long term metformin therapy way back in 1970 itself. After more than 50 years of use of metformin, we have come to know that metformin induced vit B(12) deficiency can cause neuropathy; forcing to change the recommendation from annual screening of vit B(12) levels to annual supplementation of vit B(12)...

Various regimens of folic acid-based and vitamin B12 (Vit B12) supplementations have been tried for lowering plasma homocysteine (Hcy) levels in uremic patients. However, the therapeutic potency of low-dose folic acid and Vit B12 alone is not properly understood. In this study, seventy-five patients on chronic hemodialysis (HD) therapy were randomized into three groups. The FNA group received intravenous (IV) supplementation with folinic acid 3 mg weekly; the Vit B12 group received IV supplementation with vitamin B12 1 mg weekly; and the combination group received IV supplementation with both agents weekly...

Fifty (50) cases of Leishmaniasis were included in a prospective study after making the diagnosis based on the demonstration of L D Bodies on bone marrow aspirate. Hemoglobin (Hb) and total leucocyte count (TLC) were less than 10 gm/dl and 4000 per/ml respectively in 22 out of 50 cases. Among 50 cases, 30 showed macrocytic red cell and hypersegmented neutrophils on peripheral blood smear as features of megaloblastic anemia. Out of 30 cases of leishmaniasis with megaloblastic anemia, 10 cases showed decreased reticulocyte count...

The present study was carried out to obtain an experimental model of vitamin D (vit D) insufficiency and established osteopenia (experiment 1) to then investigate whether vit D status, i.e. normal or insufficient, interferes with bone mass recovery resulting from bisphosphonate therapy (experiment 2). Rats (n = 40) underwent OVX (n = 32) or a sham operation (n = 8). The first 15 days post-surgery, all groups were kept under fluorescent tube lighting and fed a diet containing 200 IU% vit D (+D). They were then assigned during an additional 45 days to receive either +D or a diet lacking vit D (-D) and kept under 12 h light/dark cycles using fluorescent or red lighting...

BACKGROUND: A high prevalence of hyperhomocysteinemia has been reported in type II diabetic patients with documented vascular disease; hence the hypothesis that hyperhomocysteinemia may contribute to overall mortality in diabetic patients. The link between insulin and homocysteine metabolism has not been completely clarified yet; in particular, only few data are available on the effects of insulin in vivo on homocysteine metabolism in the presence of abnormalities of sulphur amino acid metabolism (methionine intolerance)...

BACKGROUND: Elevated total plasma homocysteine (tHcy) levels have been associated with vascular disease and higher mortality in patients with coronary artery disease. Graft coronary disease is a major cause of mortality in long-term survivors of heart transplantation, and hyperhomocysteinemia may be one of its causes. The objectives of our study were to establish the effectiveness of a 3 stage homocysteine-lowering algorithm in a group of 84 heart transplant (HTx) patients and to evaluate the effect of renal function on the response to homocysteine-lowering therapy...

BACKGROUND: We have previously shown in several allergy models that allergic and tolerance status with respect to allergens is associated with a somewhat different dominant specificity of IgG antibodies. The objective was to test this hypothesis in the compelling model of ultrarush venom immunotherapy (VIT), which induces clinical tolerance after only a few hours of treatment. METHODS: Antibody titers and specificity were evaluated through solid-phase ELISA using streptavidin-biotin technology in 12 patients allergic to wasp venom before and during the ultrarush procedure (at 12 h, 24 h, and 15 days)...

Calcitriol modulates in vivoand in vitro cytokine production: A role for intracellular calcium. Background. Several immunomodulatory properties of calcitriol are currently known, however, only little information is available regarding the in vivo and in vitro effects of calcitriol on cytokine production in chronic renal failure. Methods. To study the in vitro effect of calcitriol on lipopolysaccharide (LPS)-induced cytokine production, peripheral blood mononuclear cells (PBMC, 2.5 ml/ml) from 12 chronic dialytic (HD), 15 undialyzed chronic renal failure (CRF) patients and 10 normal subjects (N) were incubated at 37 degrees for 12 hours with 100 ng of LPS (E...

The measurement of urinary deoxypyridinoline (DPD) constitutes a specific and sensitive marker of bone resorption. Total and free forms of DPD are determined by chromatographic method (HPLC) after or without hydrolysis of urine, respectively. Pyrilinks-D, a new immunoassay, allows to assess directly the free forms and needs an appropriate hydrolysis step for measuring the total form. We have compared the values of free (F), total (T) and conjugated (NF) forms of DPD determined by HPLC and Pyrilinks-D, in elderly women (n = 21, mean age: 83...

Chronic refractory anemia associated with congenital hypoplastic anemia (CHA, Blackfan-Diamond syndrome) and with the 5q-syndrome may require chronic transfusion therapy to sustain life. Hemosiderosis and death from chronic iron overload may result from such a program. The effect of subcutaneous (SC) deferoxamine (DF) and supplemental oral vitamin C (vit. C) on urinary iron excretion was studied in two patients with congenital hypoplastic anemia and one patient with 5q-syndrome. In the two patients with CHA, urinary iron excretion in response to DF given SC over 24 hours was comparable to the results following intravenous (I...
