Acute Human Trichinosis Diagnosis

Purpose: To evaluate a patient for trichinellosis using the algorithm of Gottstein et al (modfiied from Dupouy-Camet et al).

Description

Gottstein et al modified an algorithm by Dupouy-Camet et al for making the diagnosis of acute trichinellosis in humans.


Group

Number

Findings

A

3

fever, myalgia, facial or eyelid edema

B

6

conjunctivitis, subungual hemorrhages, cutaneous rash, cardiac signs, neurologic signs, diarrhea

C

2

increased CK or other muscle enzymes; absolute eosinophil count > 1,000 per µL OR elevated total serum IgE concentration

D

3

positive muscle biopsy, seroconversion, positive serology using a highly specific test

 

 

Pattern

Diagnosis

(3 findings from group A) AND (2 findings from group C) AND (>=1 finding from group D)

confirmed

(any findings from group A or B) AND (>=1 finding from Group C) AND (>=1 finding from Group D)

confirmed

(3 findings from group A) AND (2 findings from group C)

highly probable

(3 findings from group A) AND (1 finding from group C)

probable

(>=1 finding from group A OR >=2 findings from group B) AND (>=1 finding from group C)

suspected

(1 finding from group A) OR (1 finding from group B) OR (1 finding from group C)

very unlikely

no findings

absent

 

where:

• In the implementation the presence of >= 1 finding from group D that does not fit into one of the above categories will be classified as highly probable.
