The many faces of Actinomycosis. Results from
a retrospective study in lceland, 1984-2007
Introduction: Actinomycosis is a rare infection caused by
Actinomyces spp. which are part of the oral, intestinal and
vaginal bacterial flora. It can invade tissue through mucosal
disruption and form abscesses which tend to be difficult to
treat and diagnose. This population-based study explores
the epidemiology and manifestations of actinomycosis in
lceland.
Methodology: All diagnosed cases of actinomycosis in
lceland 1984-2007 were identified by a computerised search
using ICD and SNOMED codes. Clinical information was
collected by chart review. The subjects were included in the
study if they fulfilled two out of five diagnostic criteria.
Results: 41 women and 25 men (mean age 45 years) met
the diagnostic criteria. The incidence rate during the first
half of the period was 0.86/year/100.000 and 1.17 during
the second half.The cervicofacial region (42%) was most
commonly affected, then the pelvis (32%), lacrimal duct
(14%), abdomen (11%) and thorax (2%). Diagnostic delay
was common. The longest delay from first symptoms to
diagnosis was 8-9 years (median 5 months) and it was
significantly shorter among patients with abdominal or
pelvic infections compared to infections of the lacrimal duct
(p=0.012). No significant difference was noted in diagnostic
delay between other groups and no patients died from the
infection.
Conclusion: This is the first population-based study of
actinomycosis. The incidence rate increases with age and
the time passing from first symptoms to diagnosis tends to
be long.
