En este estudio se analiza el papel en la profilaxis del asma por ácaros de los deshumidificadores. Se evalúa en los domicilios de 9 pacientes asmáticos con sensibilidad exclusiva frente a Dermatophagoides, la eficacia de los deshumidificadores con la reducción a los 3 meses de la humedad de los dormitorios, y su relación con la disminución en las concentraciones de alergeno mayor de ácaros D. pteronissinus I, y se comparan con 8 pacientes de iguales características que sirvieron de grupo control. En el grupo de los pacientes en los que se colocó el dispositivo deshumidificador se observó una importante reducción de la humedad relativa en el dormitorio (54,84±4,33% y 45,23±4,92%; p < 0,05), así como de las concentraciones del D. pteronissinus I (2,313±1,831 a 0,42±0,44 μg/g; p < 0,05), no ocurriendo así en los enfermos del grupo control (51,15±7,38% a 60,5±6,15%; p < 0,05 y 3,28 μg/g±4,46 a 4,24±5,10; p=NS).

This study analyzes the role of dehumidifiers in asthma prophylaxis. The efficacy of dehumidifiers in the reduction of Dermatophagoides in the bedrooms of 9 patients with specific allergies was evaluated, along with success in reducing in high concentrations of mite allergens (D. pteronissinus I). Results were compared with those for a control group of 8 patients with the same allergy. In the group in whose homes a dehumidifier was installed, there was a significant reduction in relative humidity in the bedroom (54.84±4.33% and 45.23±4.92%; p < 0.05) as well as a significant decreased in concentrations of D. pteronissinus I (2.313±1.831 to 0.42±0.44 μg/g; p < 0.05). This was not the case of patients in the control group (51.15±7.38% to 60.5±6.15%; p < 0.05 and 3.28 μg/g±4.46 to 4.24±5.10; p=NS).
