Resumen
La terapia dirigida combinada para la artritis psoriásica (APS) es utilizada por aproximadamente el 1% de los pacientes. Este estudio no encontró un aumento significativo en las infecciones graves u oportunistas en comparación con la terapia estándar, lo que sugiere una opción de tratamiento potencialmente segura.
Área de la Ciencia:
- Reumatología
- Inmunología
- Farmacología
Sus antecedentes:
- El manejo de la artritis psoriásica (APS) es un desafío, con datos limitados sobre la seguridad de la terapia dirigida combinada.
- La combinación de terapias inmunomoduladoras sistémicas es prometedora en otras enfermedades inmunomediadas.
Objetivo del estudio:
- Evaluar la utilización y la seguridad de las terapias dirigidas combinadas en pacientes adultos con APS.
- Comparar los riesgos de infección asociados con la combinación de terapias dirigidas frente a los tratamientos estándar.
Principales métodos:
- Estudio de cohorte retrospectivo utilizando la base de datos de reclamaciones comerciales de IBM MarketScan (2015-2024).
- Adultos identificados con PsA utilizando un algoritmo de afirmaciones validado.
- Para el análisis de la seguridad, se emparejó a los pacientes que recibían terapia dirigida combinada con un grupo de control en terapia estándar (relación 2: 1).
Principales resultados:
- Aproximadamente el 1% de los pacientes con APS asegurados comercialmente recibieron terapia dirigida combinada.
- Las combinaciones comunes incluyen inhibidores del TNF o inhibidores de la IL-17 con apremilast.
- No se observó un aumento significativo de las infecciones bacterianas o oportunistas graves que requieran hospitalización en el grupo de tratamiento combinado en comparación con el tratamiento estándar.
Conclusiones:
- La terapia dirigida combinada es utilizada por un pequeño subconjunto de pacientes con APS.
- Los datos actuales sugieren que la terapia dirigida de combinación para la artritis psoriásica no aumenta significativamente el riesgo de infecciones graves.
- Se necesitan más estudios a gran escala para confirmar estos hallazgos de seguridad.

01:26Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:12Relative Risk
342
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
231
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

01:27Combined Effects of Drugs: Synergism
4.7K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
