Association Between Vitamin D Status and Sepsis
Clinical Laboratory
|May 9, 2018
Summary
Lower vitamin D levels are linked to increased sepsis risk in various populations. However, vitamin D status does not appear to affect sepsis prognosis or related biomarkers.
Area of Science:
- Infectious Diseases
- Endocrinology
- Critical Care Medicine
Background:
- Vitamin D deficiency is linked to infection susceptibility.
- The relationship between vitamin D levels and sepsis risk requires further investigation.
- Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.
Purpose of the Study:
- To investigate the association between vitamin D status and sepsis risk.
- To analyze the correlation between vitamin D levels and sepsis-related factors and mortality.
Main Methods:
- A systematic literature search was conducted up to May 2017.
- Data from 24 studies were pooled to analyze vitamin D levels in sepsis cases versus non-sepsis cases.
- Associations with sepsis risk, mortality, and various biomarkers (e.g., IL-6, CRP, WBC) were examined.
Main Results:
- Sepsis patients exhibited significantly lower vitamin D levels compared to non-sepsis individuals across different ethnic groups.
- Vitamin D levels did not show a correlation with albumin, platelets, white blood cells, mortality, procalcitonin, BMI, or inflammatory markers (IL-6, CRP).
- Vitamin D deficiency was not associated with sepsis-related death.
Conclusions:
- Low vitamin D status may serve as a biomarker for sepsis risk in general populations, Caucasians, and Africans.
- Vitamin D levels do not appear to influence biochemical markers or the prognosis of sepsis.
- Further research is recommended to elucidate the role of vitamin D in sepsis.

01:30Vitamins
2.5K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

01:27Associative Learning
1.4K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

01:21Association Areas of the Cortex
9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

James Marcia's identity status model provides a framework for understanding how adolescents navigate identity formation through varying degrees of exploration and commitment. Marcia's model builds on Erik Erikson's theories of psychosocial development, focusing specifically on how adolescents reconcile individual aspirations with societal expectations. His model describes identity formation as a dynamic process where adolescents move between different states depending on their level...

01:23Role of Skin in Vitamin D Synthesis
8.0K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

1.6K
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...
