Investigación en salud materno-perinatal

La salud materno-perinatal es un área de interés en la investigación en salud y un reto en la práctica médica. La reducción de la mortalidad y de la morbilidad materna y en la población pediátrica es un problema de salud pública en nuestro país, fue uno de los objetivos del desarrollo del milenio y, actualmente, es parte de los objetivos de desarrollo sostenible de las Naciones Unidas. Por esta razón, surge la necesidad de profundizar en el tema y comprender los factores que influyen en las complicaciones del embarazo, la salud del recién nacido y los posibles desenlaces adversos de la gestación. Colombia ha estado siempre comprometida en reducir las cifras de mortalidad Materna e infantil, implementando el desarrollo y la aplicación de guías de práctica clínica y protocolos de atención

Estado nutricional de los pacientes con diagnóstico de Niemann-Pick tipo C en Colombia

Niemann Pick type C disease is a neurovisceral disease of progressive and debilitating lysosomal deposit whose symptoms have a negative impact on the nutritional status of people who suffer from it. In addition to the above, severe gastrointestinal complications have been described with the use of Miglustat, the treatment of choice for this disease, which could increase the nutritional risk of these patients.La enfermedad de Niemann Pick tipo C, es una enfermedad neurovisceral de depósito lisosomal progresiva y debilitante cuyos síntomas tienen un impacto negativo en el estado nutricional de las personas que lo padecen. Sumado a lo anterior, se han descrito complicaciones gastrointestinales severas con el uso de Miglustat, tratamiento de elección para esta enfermedad, lo cual podría incrementar el riesgo nutricional de estos pacientes

Importância de uma proposta para a implementação de um programa de triagem neonatal ampliada na colômbia

Expanded neonatal screening allows early detection of various inborn errors of metabolism. In Colombia, the conditions to carry out a national program with a high impact on public health are in place. Through a review of the international literature on the subject, this reflection on the implementation of a national neonatal screening program brings forward a complete, concise, detailed proposal for tandem mass spectrometry-expanded neonatal screening in Colombia that conforms to the legislation and the needs and characteristics of the population. Implementing such a national program has a great impact on public health and must be led by the State, with the participation and support of health professionals, academia, patient associations, and the pharmaceutical industry.El tamizaje neonatal expandido permite la detección temprana de diversos errores innatos del metabolismo.

Analysis of the cost-effectiveness of liquid biopsy to determine treatment change in patients with her2-positive advanced breast cancer in Colombia

Background: Breast cancer is highly prevalent worldwide and leads to high health-care costs. HER2-positive subtype represents 30% of all breast cancers and is associated with a poor prognosis. Patients treated with anti-HER2 therapies frequently develop resistance and require pharmacological treatment change. Liquid biopsy is a minimally invasive and an easily accessible technique, with high sensitivity and specificity, to detect molecular treatment resistance even before the onset of clinical manifestations and can thus be used to reduce unnecessary anti-HER2 treatment costs. Objective: To evaluate the cost-effectiveness of using liquid biopsy (ctDNA detection) to determine treatment change in women with HER2-positive advanced breast cancer in Colombia. Methodology: We performed an economic evaluation using decision tree modeling and deterministic analyses based on literature search for first and second lines of treatment (trastuzumab, pertuzumab, docetaxel, and TDM1); resistance; outcomes; and sensitivity and specificity of tests detecting molecular resistance. The effectiveness was measured using quality-adjusted life year (QALY) score, and costs were obtained from databases with national validity, suppliers, the Colombian Drug Price Information System (SISMED), and local studies. Results: The use of liquid biopsy (ctDNA detection) with conventional treatment was more expensive and less effective than conventional treatment without liquid biopsy (US $177,985.35 and 0.533889206 QALY, respectively). The incremental cost with liquid biopsy was US$7,333.17 and the incremental effectiveness was 0.00042256 QALY relative to the conventional method. Conclusion: Including liquid biopsy in the treatment of HER2-positive advanced breast cancer was considered currently inapplicable in Colombia because it was not cost effective. Our results open a window of opportunity to improve the development and implementation of ctDNA testing in Colombia, potentially reducing current costs. More evidence is required on the utility of this test, depending on the financial capacity of Colombia and other countries. © 2020 Sánchez-Calderón et al

AR-V7 as a Biomarker for Resistance to Treatment with Abiraterone/Enzalutamide in Three Latin American Countries: A Hypothetical Cost-Saving Analysis.

Prostate cancer is the most incident and one of the deadliest male cancers in Latin America. Treatment for patients with metastatic castration-resistant prostate cancer (mCRPC) includes androgen receptor signaling inhibitors such as abiraterone and enzalutamide, for which androgen receptor splice variant 7 (AR-V7) has emerged as a biomarker for primary resistance. Our study sought to analyze the potential economic impact of the use of AR-V7 detection as a treatment indicator in patients with mCRPC in three Latin American countries. A hypothetical cost prediction model for the use of noninvasive circulating tumor cell-based AR-V7 testing as a treatment indicator for patients eligible for treatment with abiraterone/enzalutamide was conducted using available information on treatment and testing costs from Mexico, Argentina, and Colombia. At an estimated prevalence of AR-V7 positivity of 20%, the use of upfront AR-V7 genetic testing resulted in annual net savings of $9,801,669.97,$6,390,055.75, and $3,096,780.91 in Mexico, Argentina, and Colombia, respectively. A direct relationship between AR-V7 positivity prevalence and net savings was found. The use of a noninvasive AR-V7 detection assay as a treatment indicator tool in patients eligible for treatment with abiraterone or enzalutamide in Latin America could be a cost-effective approach for the management of these patients. Additional efforts are needed to accurately determine the incidence of castration-resistant prostate cancer cases and the prevalence of AR-V7 positivity in Latin America in order to predict the potential economic benefit of its clinical use. In Latin America, prostate cancer is the most frequently diagnosed cancer in men, and the burden of this disease is expected to double in this region by 2030. Noninvasive detection of androgen receptor splice variant 7 (AR-V7) is being currently validated as a predictive biomarker for benefit with androgen receptor signaling inhibitor therapy in patients with metastatic castration-resistant prostate cancer (mCRPC). This hypothetical cost-saving analysis shows that AR-V7 testing in peripheral blood of patients with CRPC eligible for treatment with abiraterone or enzalutamide might represent a cost-effective strategy to select patients who will benefit from AR-axis-directed treatment in three Latin American countries
