Acne Vulgaris Clinical Trial
Official title:
Effectiveness of Comedone Extraction and Oral Doxycycline In The First Line Treatment of Moderate Acne Vulgaris: Study on HIF-1 Alpha Expression
The objective of the study was to evaluate the effectiveness of comedone extraction compared to oral antibiotics as the main therapy of moderate acne vulgaris (MAV); and to determine the expression of HIF-1 alpha by examining the immunohistochemistry and ELISA as a sign of hypoxia/anoxia in MAV lesion. This was a randomized, placebo-controlled clinical trial that was performed in 2015 at three different dermatology clinics in Indonesia, Cipto Mangunkusumo Hospital Jakarta, Gatot Soebroto Army Hospital Jakarta, and PT. Mattel Indonesia, Cikarang. One hundred and twenty eight subjects with moderate acne vulgaris were recruited and randomized to receive either oral doxycycline or comedone extraction for six weeks. Subjects who had acne lesion and the back area were offered skin lesion biopsy to evaluate immunohistochemistry and ELISA before administration of medication. The main outcome was total reduction of inflammatory and non inflammatory lesions, evaluated every two weeks.
Acne vulgaris (AV) is a polymorphic disease, characterized by inflammatory and
noninflammatory lesions. Systemic antibiotics play a role as the first line therapy of
moderate acne vulgaris treatment. Since bacterial resistance tends to increase, alternative
therapy for moderate acne vulgaris is needed.
This study aims to evaluate the effectiveness of comedone extraction compared to oral
antibiotics as the main therapy of moderate acne vulgaris; and to etermine the expression of
HIF-1 alpha by examining the immunohistochemistry and ELISA as a sign of hypoxia/anoxia in
MAV lesion.
This was a randomized, placebo-controlled clinical trial that was performed in 2015 at three
different dermatology clinics in Indonesia, Cipto Mangunkusumo Hospital Jakarta, Gatot
Soebroto Army Hospital Jakarta, and PT. Mattel Indonesia, Cikarang.
One hundred and twenty eight subjects, aged between 15 and 50 years, with moderate acne
vulgaris were recruited and randomized to receive either oral doxycycline (100 mg) or
comedone extraction for six weeks. Subjects who had acne lesion and the back area were
offered skin lesion biopsy to evaluate immunohistochemistry and ELISA before administration
of medication.
At each follow-up visit, subjects were asked to grade the overall response and questioned
regarding adverse events. The objective or main outcome was total reduction of inflammatory
and noninflammatory lesions.
