Erupción de luz polimórfica hereditaria en los indios americanos. Fotoprotección y prevención de la pioderma
JAMA
|September 26, 1980
Resumen
El tratamiento de erupción de luz polimórfica hereditaria (HPLE) en los indios americanos mostró que el betacaroteno oral proporcionó fotoprotección para muchos. Las terapias combinadas mejoraron aún más los resultados para esta condición sensible a los rayos UV.
Área de la Ciencia:
- Dermatología Dermatología dermatología.
- Fotobiología Fotobiología.
- Epidemiología La epidemiología.
Sus antecedentes:
- La erupción de luz polimórfica hereditaria (HPLE) afecta a los indios americanos, causando sensibilidad a la radiación ultravioleta de onda larga.
- Los protectores solares convencionales ofrecen un beneficio limitado debido a la sensibilidad específica a los rayos UV en pacientes con HPLE.
Objetivo del estudio:
- Para evaluar la eficacia de la dihidroxiacetona, la lewsona y el betacaroteno en el tratamiento de HPLE.
- Para explorar el vínculo potencial entre la HPLE y la pioderma estreptocócica y la glomerulonefritis en los indios americanos.
Principales métodos:
- Tratamiento de 46 pacientes con EPLP con dihidroxiacetona/lawsona tópica, betacaroteno oral o terapia combinada.
- Estudios epidemiológicos para investigar las asociaciones con las infecciones estreptocócicas.
Principales resultados:
- El betacaroteno oral proporcionó una fotoprotección adecuada para 33 pacientes.
- Cuatro pacientes adicionales lograron protección con agentes orales y tópicos combinados.
- Los datos epidemiológicos sugieren que HPLE puede ser un factor en la piodermia estreptocócica y la glomerulonefritis.
Conclusiones:
- El betacaroteno oral y la terapia combinada son prometedores para el manejo de HPLE.
- HPLE puede desempeñar un papel en la etiología de la pioderma estreptocócica y la glomerulonefritis en la población indígena americana.

Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

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...

Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
