RESUMO
BACKGROUND: In recent years, the role of vitamin D (VD) as a protective factor in cardiovascular disease has been recognized. Thus, there is a need to study the effect of vitamin D supplementation in the control of different cardiovascular risk factors and metabolic syndrome, especially in young populations where few studies have been conducted. METHODS: Pilot study of a randomized, parallel two-arm, triple-blind clinical controlled trial in 150 adolescents and young adults in the city of Bucaramanga-Colombia. The intervention group will receive 1000 IU of VD and the control group 200 IU of VD daily for 15 weeks. The main outcomes are: serum calcifediol levels (25(OH) D), body mass index and lipid profile; secondary outcomes are complementary to the previous ones (skin folds, waist-hip ratio). Other variables will be analyzed such as assessment of dietary intake, physical activity, sun exposure, cigarette and tobacco consumption and compliance with VD supplementation. DISCUSSION: This study is innovative since there is little evidence from clinical trials in adolescents and young adults; similar studies are not known in our context. The results of this study may facilitate the recommendation of oral vitamin D supplementation in the population of interest. In addition, it is a low-cost and easy-to-apply intervention that could contribute to the formulation and implementation of health policies. TRIAL REGISTRATION: NCT04377386.

La leishmaniasis es un problema creciente de salud pública, que produce un gran impacto social. La leishmaniasis laríngea y sin puerta de entrada evidente es rara, en especial en pacientes inmunocompetentes. Describimos un caso de leishmaniasis laríngea con extensión traqueal y estenosis secundaria en un adolescente previamente sano y sin factores de riesgo ambiental o personal.
Leishmaniasis is a growing public health problem and it produces a great social impact. Laryngeal leishmaniasis without obvious gateway is rare; especially in immunocompetent patients. We report a case of laryngeal leishmaniasis with tracheal involvement and stenosis on a previously healthy teenager without environmental or personal risk factors.
