ABSTRACT

OBJECTIVE:

Curaçao (12 degrees 10N, 69 degrees 0W) is characterized by whole year abundant sunshine (8-10 hours/day). We challenged the automatic assumption that people living in tropical countries do not have a high risk of vitamin D deficiency, and investigated the vitamin D status in a tropical environment.

METHODS:

For this, we selected fiftytwo elderly people with little or no exposure to direct sunlight [median 84 (60-96) years; 34 females, 18 males] and who were cared for by community nurses or lived in retirement or nursing homes. Furthermore, six rehabilitating orthopaedic patients [median 72 (38-90) years; one female, five males] were included. Serum 25(OH)D, calcium, phosphate, parathyroid hormone (PTH) and creatinine were measured. Those exhibiting elevated creatinine, PTH or both had their 1,25dihydroxyvitamin D [1,25(OH)2D] examined.

RESULTS:

Serum levels of 25(OH)D below 25, 50 and 75 nmol/L were detected in, respectively, seven (12%), 22 (38%) and 48 (83%) of the fiftyeight persons. Four persons had combined high creatinine and PTH, and low 1,25(OH)2D, which was not known by their caregivers.

CONCLUSION:

Abundant sunshine outdoors is no guarantee for vitamin D sufficiency. More attention is needed for vitamin D deficiency in risk groups living in tropical areas and elderly persons with poor kidney function.
RESUMEN

OBJETIVO:

Curazao (12 grados 10N, 69 grados 0W) se caracteriza por su abundante luz solar durante todo el año (8-10 horas/día). Ponemos en duda la suposición automática de que los habitantes de países tropicales no poseen un alto riesgo de deficiencia de vitamina D, e investigamos los niveles de vitamina D en un ambiente tropical.

MÉTODOS:

Para ello, seleccionamos a cincuenta y dos personas de avanzada edad [mediana 84 (60-96) años; 34 mujeres, 18 hombres] con poca o ninguna exposición directa a la luz solar, cuidados por enfermeras comunitarias o que vivían en hogares de ancianos o casas de retiro. Además, se incluyeron seis pacientes bajo rehabilitación ortopédica [mediana 72 (38-90) años; una mujer, cinco hombres]. Se les realizaron las siguientes mediciones 25(OH)D en suero, calcio, fosfato, hormona paratiroidea (HPT), y creatinina. A todos aquellos que mostraron niveles elevados de creatinina, de HPT, o de ambas, se les realizó un examen de 1,25dihidroxivitamina D [1,25(OH)2D].

RESULTADOS:

Se detectaron niveles séricos de 25(OH)D por debajo de 25, 50 y 75 nmol/L en siete (12%), 22 (38%) y 48 (83%) de las cincuenta y ocho personas, respectivamente. Cuatro personas presentaron una combinación de elevada creatinina y HPT, y bajo 1,25(OH)2D, datos desconocidos para sus cuidadores.

CONCLUSIÓN:

La abundancia de luz solar exterior no es garantía de suficiencia de vitamina D. Se necesita prestar mayor atención a la deficiencia de vitamina D en los grupos de riesgo que viven en áreas tropicales, así como a las personas de edad avanzada con pobre función renal.
