2 METHODS
This is a descriptive retrospective research using
medical record data from patients that have been
diagnosed as an ACD and have been performed patch
test in Dermato-Venereology clinic dr. sardjito
central general hospital Yogyakarta from 2012-2016
using standard serial patch test and listed for five of
the most common founded allergen. The listed
allergen was analyzed for its activity pattern showed
on patch test interpretation from 48, 72, 96 hours.
Each allergen was compared for its activity from 48
to 72 hours, 48 to 96 hours, and 48-72-96 hours then
calculated for percentage.
3 RESULTS
Five of most common founded positive allergen listed
were Nickel sulphate, Potassium dichromate, Cobalt
chloride, Fragrance mix I, and Fragrance mix II.
Interpretation on patch test result for Nickel sulphate,
Potassium dichromate, Cobalt chloride at 48-72 hours
and 48-96 hours showed dominantly sensitizer
pattern (ascended). Interpretation for Fragrance mix
I, and Fragrance mix II showed sensitizer pattern on
interpretation at 48-72 hours, while for interpretation
at 48-96 hours showed dominantly irritant pattern. No
specific dominant pattern was showed on
interpretation at 48-72-96 hours, as minimal
limitation score as sensitizer and irritant showed on
table 2.
4 DISCUSSION
The prevalence of contact allergy is rising worldwide.
This results in high costs for health care systems and
the economy as well as in an impairment of the
quality of life for the patients.(Nguyen, 2008),(
Kohl,2002), (Lunder, 2000). Contact dermatitis is
often localized on the hands, a highly visible area of
the body, thus drawing attention and causing
difficulties in social interaction. Jowett and Ryan
found that, in general, 38% of patients with eczema
noticed interference with social life ( Jowett,1985). In
a follow-up study of 954 patients with contact
dermatitis, 61% reported that they had lost time from
work due to their skin disease ( Mälkönen, 2009).
About 6% of all patients had been off work for longer
than 12 months continuously.
Each allergen or chemical substance has been
studied and analyzed then listed on some literation,
but visible clinical manifestation caused by those
allergen or chemical substance could be varied, and
not always as a result of its main characteristic. (
Thyssen,2007) In Europe about 20% of the general
population suffers from contact allergy to at least one
contact allergen. Most common are allergies to
nickel, fragrances and preservatives. Allergic
reactions to chromate and p-phenylenediamine (PPD)
are generally less common but occur frequently in
occupationally exposed subgroups of the population.
Contact dermatitis occurs twice as frequently in
women as in men and often starts at a young age, with
a prevalence of 15% in 12–16 year olds. (
Nosbaum,2009). Literally said that all of those
allergen most common founded positive on patch test
for ACD patient at Dermato-venereology clinic
central general hospital Yogyakarta 2012-2016 which
are Nickel sulphate, Potassium dichromate, Cobalt
chloride, Fragrance mix I and Fragrance mix II were
mainly irritant and sensitizer secondarily (ASTM,
2005), (Sciencelab, 2013), (Sheet,2009). Dominant
activity pattern as sensitizer showed on interpretation
on patch test result for Nickel sulphate, Potassium
dichromate, Cobalt chloride at 48-72 and 48-96
hours. Dominant activity pattern as sensitizer showed
on interpretation on patch test result for Fragrance
mix I and Fragrance mix II at 48-72 hours while
dominant activity pattern as irritant showed on
interpretation at 48-96 hours. Interpretation at 48-72-
96 hours continuously showed no specific allergen
pattern. Contact dermatitis is a pattern of
inflammatory response of the skin that may occur as
a result of contact with external factors (allergens,
irritants). The clinical picture is a polymorphic
pattern of inflammation of the skin characterized by a
wide range of clinical features like itching, redness,
scaling, erythema, vesiculation, and clustered
papulovesicles. In chronic cases, assuring,
hyperkeratosis, and lichenification occur. The variety
of morphologies and natural histories makes it
difficult to define a widely accepted, standardized
definition of the disease, which is needed to compare
epidemiological studies. (Diepgen,1999)
The difference on clinical manifestation could be
caused by combination of endogenous factor (atopic)
and exogenous factor (allergen concentration), and
the balance of sensitize and irritant activity. Skin
contact with irritants and/or allergens is a necessary
condition of contact
