Summary
Vitamin D toxicity can occur from self-medicating with high doses, leading to acute kidney injury. Regular monitoring of vitamin D blood levels is crucial for safe supplementation and avoiding adverse effects.
Area of Science:
- Endocrinology
- Nephrology
- Nutritional Science
Background:
- Growing awareness of vitamin D benefits and deficiency fuels supplementation interest.
- Over-the-counter availability increases self-medication with vitamin D supplements.
Observation:
- A case of vitamin D toxicity (VDT) is presented following self-medication with excessive doses.
- The patient presented with acute kidney injury (AKI) and elevated serum 25(OH)-vitamin D levels.
Findings:
- Treatment with intravenous hydration, loop diuretics, and prednisone led to clinical and biochemical improvement.
- The patient's laboratory values reflected recovery from acute kidney injury.
Implications:
- Healthcare providers must be aware of vitamin D toxicity as a potential side-effect of supplementation.
- Regular monitoring of vitamin D blood levels is essential for appropriate dosage titration.
- Public education on the risks of self-medicating with high-dose vitamins is critical.

01:23Role of Skin in Vitamin D Synthesis
7.2K
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...

2.1K
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...

01:24Chronic Kidney Disease II: Clinical Manifestations
434
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

3.9K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

01:25Role of Vitamins in Maintaining Bone Health
4.7K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...
