Chlamydien-IgM-rELISA medac
Recombinant enzyme immunoassay for the detection of specific IgM antibodies to chlamydial LPS in human serum Chlamydiae are gram-negative bacterial pathogens. They have an obli-
gate intracellular life cycle in mucosal surfaces, endothelial cells,
smooth muscle cells, and according to recent findings in certain tis-
sue structures of the central nervous system. Chlamydiae depend on en-
ergy-rich phosphates of their host cells and are therefore energy
parasites.
The genus chlamydia comprises four species: C. pneumoniae, C. tracho-
matis, C. psittaci
,
and C. pecorum. C. pneumoniae and C. trachomatis
are obligate pathogens of humans. C. psittaci is pathogenic for humans
and a variety of animal species. To date, C. pecorum has been isolated
from animals only.
Chlamydia trachomatis is one of the most frequent sexually transmitted
pathogens worldwide. It causes infections of the urogenital tract and
the eye. In most cases C. trachomatis infections are asymptomatic.
This results in a variety of chronic diseases, which are sustained by
the ascended and persisting agents. The clinical pictures include in
women: Endometritis, adnexitis, periappendicitis, perihepatitis, and
reactive arthritis. As a consequence of repeated adnexitis the tubes
occlude which results in sterility.
In men the pathogens may ascend to the epididymis (Æ epididymitis) and
into the prostate gland (Æ prostatitis) after incomplete or unsuccess-
ful treatment of urethritis. A reduction of fertility has been discus-
sed in these cases. Furthermore, post-urethritic reactive arthritis is
known in men.
In newborns C. trachomatis can be transferred during delivery from the
infected birth channel to the infant and can cause neonatal conjuncti-
vitis and/or pneumonia.
Chlamydia pneumoniae infections occur worldwide. In addition to flu-
like illness, the clinical picture includes sinusitis, pharyngitis,
bronchitis, chronic obstructive pulmonary disease, atypical pneumonia,
and reactive arthritis. A causal involvement in infection-conditioned
asthma, sarcoidosis, atherosclerosis, acute myocardial infarction,
stroke, multiple sclerosis, and late-onset of Alzheimer’s disease has
been discussed.
Chlamydia psittaci infects birds and mammals, which may transmit the
pathogen to humans. The resultant frequently severe pneumonias may
lead to life-threatening conditions if no targetted antibiotic inter-
vention is started rapidly.
The usual laboratory methods for the detection of chlamydia infections
include antigen and antibody determinations. The antigen detection
(IFA, ELISA, PCR) is of value for the diagnosis of peripherally local-
ized infections. In ascended courses of disease the detection of the
pathogen is limited and has to be complemented by serology. Sero-
logical methods include complement fixation test, IFA, MIF, genus- and
species-specific ELISA systems.
Chlamydiae contain as common immunodominant antigen the lipopolysac-
charide (LPS), to which the first immune reaction is directed. The
corresponding antibodies are already detectable within a few days af-
ter infection and, thus, allow early diagnosis. The use of paired sera
enables the discrimination of current infections, reinfections, and
reactivations (defined titer increases) from chronic persistent ones
(constant antibody titers). Because of the limited persistence of the
LPS antibodies after successful eradication of the pathogens, the dia-
gnosis of current infections is obviously not influenced by past in-
fections.
The Chlamydien-IgG-, IgA-, and IgM-rELISA medac are based upon a
molecularly defined, genetechnologically produced antigen. It is an
exclusively chlamydia-specific fragment from the LPS which has not
been found in any other bacterial LPS. The comparison of sera from
blood donors with sera from patients with urogenital or respiratory
infections has shown, that antibodies to chlamydial LPS are detected
more frequently in patients than in blood donors.
As the reaction is genus-specific, the test result will not differen-
tiate betweeen the chlamydia species. However, as the clinical picture
already will hint to the suspected chlamydia species and additionally
all the chlamydiae show an equal sensitivity towards specific antibi-
otics, the genus-specific reactivity does not hamper the consequences.
TEST PRINCIPLE

The plate is coated with chlamy-dia-specific recombinant LPS frag-ment. The chlamydia-specific LPS antibo-dies from the specimen bind to the antigen. Peroxidase-conjugated anti-human IgM antibodies bind to the IgM an-tibodies (P = peroxidase). Incubation with TMB-substrate (*).
The reaction is stopped by the ad-
dition of sulfuric acid. The ab-
sorption is read photometrically.

Advantages of the test

Do not use the reagents after the expiry date. REAGENTS AND MATERIALS REQUIRED BUT NOT PROVIDED
2.1. Water for injection (H2O redist.). Use of deionised water can 2.2. Adjustable micropipettes. 2.3. Clean glass or plastic containers for dilution of wash buffer 2.4. Suitable device for microplate washing (e.g. multistepper or 2.5. Incubator for 37 °C. 2.6. Microplate reader with filters for 450 nm and 620 - 650 nm. PREPARATION OF THE REAGENTS

Before starting the test procedure all kit components must be equili-
brated to room temperature (RT).
Calculate the number of wells required.
3.1. Microplate
After each removal of wells the aluminium bag has to be tightly resealed together with the desiccant. Storage and stability of the wells are indicated under point 1. Mix one volume of wash buffer (10x) with nine volumes of water for injection (e.g. 50 ml wash buffer (10x) with 450 ml water). 10 ml of diluted wash buffer are needed for eight wells. Crystals in the wash buffer (10x) have to be dissolved by warm-
ing (max. 37 °C) and/or stirring at RT.


Do not mix test specific reagents (microplate, controls, conjugate)
from different kit lots. In contrast to that, sample diluent, wash
buffer, TMB-substrate, IgG/Rf-absorbent and stop solution are gener-
ally exchangeable in all Chlamydia and Mycoplasma-ELISA medac.

Reagents from other manufacturers must not be used in general.

Valid and reproducible results are only obtained if the test proce-
dure is precisely followed.

4. SPECIMEN

4.1. The test is suitable for serum samples, but not for plasma.
4.2. Pretreatment of sera, e.g. inactivation, is not necessary. How-
ever, they should neither be contaminated with microorganisms nor contain red blood cells. 4.3. The sera are employed at a final dilution of 1:50 after IgG/Rf PROCEDURE

5.A. IgG/RF ABSORPTION
Attention:

The controls are ready to use (no absorption necessary).
The volumes indicated in the following are for single determi-
nations only.


5.A.1. Serum: 10 µl serum are diluted with 240 µl sample diluent (di-
5.A.2. Absorption: 30 µl IgG/Rf-absorbent and 30 µl diluted serum are mixed (dilution 1:50) and incubated for 15 min at RT. Alternative: The absorption can be performed overnight at 2 - 8 °C.
5.B. TEST
PROCEDURE

5.B.1. Cut the aluminium bag above the zip fastener and take out the
required number of microplate wells (see 3.1.). Microplate wells are ready to use and do not have to be pre-
washed.

5.B.2. Pipette 50 µl of sample diluent into the well A1 as blank (see 6.A.), 50 µl of the negative control in duplicate, and each 50 µl of the positive control and the diluted patient samples for If necessary, the microplate wells can be kept in a humid
chamber up to 30 min at 2 - 8 °C before proceeding.


5.B.3. Incubate the microplate wells for 60 min (± 5 min) at 37 oC
(± 1 °C) in a humid chamber or sealed with incubation cover foil. 5.B.4. After incubation wash the microplate wells three times with each 200 µl wash buffer per well. Pay attention that all wells are filled. After washing tap microplate wells on filter pa-per. Do not allow the wells to dry out! Proceed immediately!

5.B.5. Add conjugate (coloured red) to each well.
50 µl of conjugate have to be pipetted into the wells if the
test is done manually.

Please note:
When working with automated instruments, 60 µl of conjugate
have to be pipetted into each well due to a higher evaporation
in the incubation chambers of the automates.
The principal suitability of the test for automation could be
shown during validation. Nevertheless we recommend to verify
the compatibility with the automate employed.

5.B.6. Incubate the microplate wells again for 60 min (± 5 min) at 37 oC (± 1 °C) in a humid chamber or sealed with incubation cover foil. 5.B.7. After incubation wash microplate wells again (see 5.B.4.). 5.B.8. Add 50 µl of TMB-substrate to each well and incubate the mi- croplate wells for 30 min (± 2 min) at 37 oC (± 1 °C) in a hu-mid chamber or sealed with incubation cover foil in the dark. Positive samples turn blue. 5.B.9. Stop the reaction by adding 100 µl of stop solution to each
Clean microplate wells from underneath before the photometric reading
and take care that there are no air bubbles in the wells.
The reading should be done within 15 min after adding the stop solu-
tion.

6.A. CALCULATION OF RESULTS (VALIDITY)


Read OD values at 450 nm (reference wavelength 620 - 650 nm). Subtract the OD value of the blank (well A1) from all other OD values. The OD value of the blank has to be < 0.100.
The mean OD value of the negative control has to be < 0.200.
The OD value of the positive control has to be > 0.800.

Cut-off = Mean OD value of the negative control + 0.370

Grey zone = Cut-off ± 15 %

Repeat the run if the results do not meet the specification.


6.B. EVALUATION OF RESULTS

6.B.1.QUALITATIVE


6.B.2.QUANTITATIVE
With the Chlamydien-IgM-rELISA medac the sera have to be titrated if
endtiter determination is desired.

6.C. INTERPRETATION OF THE RESULTS
6.C.1.CRITERIA FOR SIGNIFICANT TITER INCREASES
For the diagnosis of current, fresh infections, reinfections, reacti-
vations (significant titer increases) and discrimination from persis-
tent infections (constant antibody titers) we principally recommend
the use of paired sera. They should be obtained 10 - 14 days apart.
The following criteria have been described as a possibility for the
assessment of significant titer increases (Persson et al., Verkooyen
et al.):
specific IgG or IgA antibody titers
specific IgG and IgA antibody titers
SPECIFIC IgM INTERPRETATION

Possible
Interpretation
tion. Retest IgM after 10 - 14 days and test for IgA and IgG. dia IgM antibodies. In cases of jus-tified clinical suspicion test for IgA and IgG. The IgM results should always be interpreted in connection with IgG and/or IgA, the clinical picture and additional diagnostic parameters. Samples with OD values within the grey zone should be retested together with a fresh specimen taken 14 days later in order to determine a titer change. High concentrations of hemoglobin and of bilirubin in serum do not have an influence on the results. In rare cases, high lipid concentrations in serum may influence the test results. Cross-reactivities with antibodies to parvovirus B19 cannot be excluded in individual cases.
Comment:
In cases of fresh acute chlamydial infections the serological anti-
body results may be negative despite clinics and positive antigen de-
tection. If a serological confirmation of a positive antigen result
or if a follow-up is desired we recommend to test after 10 - 14 days
for seroconversion.
7. PERFORMANCE
CHARACTERISTICS

We determined the following performance characteristics during the
diagnostic evaluation.
7.A. PREVALENCE

Sera from various patients cohorts (culture-positive, -negative STD
patients, prostitutes, infertile females, infertile males, patients
with rheumatic diseases, patients with chronic obstructive respira-
tory diseases [COPD]), and controls (pregnant women, 2 blood donor
cohorts) were investigated for the determination of LPS antibody
prevalence.

Do not exchange the vials and their screw caps in order to avoid cross contamination. The reagents have to be sealed immediately after use in oder to avoid evaporation and microbial contamination. After use, the reagents have to be stored as indicated to guar-antee the shelf life. After use, all components of the testkit should be stored in the orginal package, in order to avoid mixing up the reagents of other test systems or lots (see also 3.).
HEALTH AND SAFETY INFORMATION


The local occupational safety and health regulations have to be regarded. Reagents of human origin have been tested and found to be nega-tive for HBsAg, for antibodies to HIV-1/2 and to HCV. Neverthe-less, it is strongly recommended that these materials as well as those of animal origin (see kit contents), should be handled as potentially infectious and used with all necessary precautions. DISPOSAL CONSIDERATIONS

Residues of chemicals and preparations are generally considered as hazardous waste. The disposal of this kind of waste is regulated through national and regional laws and regulations. Contact your lo-cal authorities or waste management companies which will give advice on how to dispose hazardous waste. Date of issue: 01.07.2008
