Summary
COVID-19 infection may trigger telogen effluvium (TE), a type of hair shedding. This study found TE in patients recovering from COVID-19, suggesting a link between the virus and hair loss.
Area of Science:
- Dermatology
- Infectious Diseases
- Hair Biology
Background:
- Telogen effluvium (TE) is diffuse hair shedding occurring 2-3 months post-stressor.
- COVID-19 infection imposes significant physiological and psychosocial stress.
- The pandemic context may influence stress-related conditions like TE.
Purpose of the Study:
- To investigate the potential association between COVID-19 infection and telogen effluvium.
- To describe the clinical presentation of TE in patients with a history of COVID-19.
Main Methods:
- Retrospective review of electronic medical records of 552 COVID-19 patients.
- Identification and case series description of 10 patients diagnosed with TE attributed to COVID-19.
Main Results:
- Ten patients (mean age 48.5 years, 90% female) developed TE post-COVID-19.
- Hair shedding began approximately 50 days after initial COVID-19 symptoms.
- Most patients received various treatments for COVID-19, and 70% were hospitalized.
Conclusions:
- COVID-19 infection may be a significant trigger for telogen effluvium.
- Further research is needed to confirm the prevalence and long-term outcomes of COVID-19-associated TE.
- Other factors, including medications and pandemic-related stress, could also contribute to TE.

Accessory Structures of the Skin: Hair Growth and Types
2.1K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

COPD: Pathogenesis and Clinical Features
1.6K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Multipotency and Niche of Bulge Stem Cell
4.0K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Long-term Depression
2.8K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
