What This Study Did, in Plain Language

What Was Tested

The paper reports a study of Cyanocobalamin (Vitamin B12) in the context of anemia, published as a controlled clinical trial.

Since several different proteins are adsorbed by LDL apheresis beside pro-atherogenic lipoproteins, the researchers examined the modification of the full blood count, plasma iron, vitamin B12, folic acid, and hemolysis by LDL apheresis.

The patients' full blood count, iron metabolism (plasma iron, ferritin, transferrin, transferrin saturation), vitamins involved in erythropoiesis (vitamin B12 and folic acid), and markers of hemolysis (haptoglobin and free hemoglobin) were analyzed directly before and after LDL apheresis.

Who Took Part

The study group was 19 patients.

By PubMed's age tags, the people studied were middle-aged adults, both men and women.

Nineteen patients (55 (50-59) years, 4 female, 15 male) undergoing chronic LDL apheresis due to mixed dyslipidemia (N = 17), homozygous familiar hypercholesterolemia (N = 1) or isolated elevated lipoprotein(a) (N = 1) were included in this study.

How the Study Was Run

They were treated with direct adsorption of lipoproteins (DALI; N = 6), heparin-induced LDL-precipitation (HELP; N = 7) or double filtration plasmapheresis (DFPP; N = 6).

What Was Measured

The subject headings attached to it are Anemia, Blood Component Removal, Dyslipidemias, Erythropoiesis, Ferritins, Filtration and Heparin.

What This Means in Plain Language

This is a controlled clinical trial of Cyanocobalamin (Vitamin B12) in 19 patients in people with anemia.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 2010 (Therapeutic apheresis and dialysis : official peer-reviewed journal of the International Society for Apheresis, the Japanese Society for Apheresis, the Japanese Society for Dialysis Therapy), a journal based in Australia.
