EBV and numerous associated diseases

G. Glady

European Bioimmun(g)en Medicine Association

(EBMA), France

EBV is probably the most spread virus within the human race,

because about 90% of the general adult population are carriers of it.

The biological diagnosis is at present codified very well and

allows to detect easily the “healthy carriers”, those which are nor-

mally immunized.

It turns out nevertheless, that those are not necessarily the most

numerous, and that there is a large number of patients disturbed

by the presence of the virus, and which are going to develop or a

persistent primary infection or a so-called reactivation.

In both cases aforesaid it is not any more question about some

process of infectious nature, but about various disturbances affect-

ing the immune system of some different way in continuation of

the interactions with the virus.

The purpose of this to-day presentation is going to show exactly

to what extent the EBV is capable, by using the immunitary

resources of the patient to favor the development of a large number

of diverse pathological disorders, which are involved in the genesis

of a set of diseases being responsible of often very different noso-

logical frames, and whose evolution will be favorably influenced by

EBV neutralization.

This last one can be realized by applying a therapy with an epi-

genetic modulation by means of micro-RNAs, those of the virus but

of the host-cell too, used within the framework of a sub-lingual

immunotherapy.

Background:

The aim of this retrospective study was investi-

gation of malignancy associated with EBV (Epstein-Barr Virus) and

viral load by real-time polymerase chain reaction (Real-Time PCR)

in paediatric patients with liver transplant.

Material and methods:

Thirty-two paediatric patients that

applied from Gazi University Faculty of Medicine, Department of

Paediatric Gastroenterology who were liver transplant between

March 2014 and January 2016. EBV VCA IgM, VCA IgG, EBNA IgM,

EBNA IgGve EA IgGantibodieswere investigatedby Enzyme-Linked

Immunosorbent Assay (ELISA) (DIA PRO Milano, Italy) method in

clinical samples of patients that required of serological analyses.

Serological profiles of patients were determined and EBV DNA was

investigated quantitatively by Real-Time PCR. DNAs were extracted

by “Spin-Column” method (High Pure Viral Nucleic Acid Kit, Roche,

Germany). Isolated DNAs were amplified by Real-Time PCRmethod

in LightCycler 2.0 (Roche, Germany) device and the results were

evaluated quantitatively.

Results:

In our study 18 females (%56.3), 14 males (%43.7) pae-

diatric patients ages between 1 and 18 years were investigated.

EBV DNAwas positive for %15.6 (5/32) of patients by Real-Time PCR

method. EBVDNA andVCA IgMpositivitywas not detected simulta-

neously. The patients that EBV DNA detected were diagnosed with

Biliary atresia, Progressive familial intrahepaticcholestasis (PFIC),

Wilson, Chronic liver failure and all patients had liver transplanta-

tion. There was no rejection in EBV-positive patients and Burkitt’s

lymphoma developed in one positive patient (1/5). ALT, AST, GGT

values were within normal limits in EBV DNA positive patients. EBV

DNApositive patientswere treatedwith acyclovir, ganciclovir or val

ganciclovir without changing immunosuppressive therapy. One of

the EBV positive five patients, have not participated in the treat-

ment process and have not applied again to hospital; one patient

died due to Burkitt’s lymphoma; for the remaining three patients,

it was observed that the process was continuing with therapy and

recurrent infections. It is revealed that the most common symp-

toms are fever, vomiting, diarrhea and tonsillitis in EBV positive

patients. EBV DNA was found

10

4

copies/ml for the 80% (4/5) of

the studied samples and 20% (1/5) had

10

5

copies/ml.

Conclusion:

EBV infection is a high risk factor in immuno-

suppressive patients especially transplantation patients, EBV was

important for these patients’ follow-up and prognosis. Monitor-

ing EBV DNA levels closely with Real-Time PCR methods is helpful

for evaluating the changes in the clinical course and early diagno-

sis. The patient, who was diagnosed with Burkitt’s lymphoma, had

high viral load (

10

5

copies/ml); therefore, in immunosuppress-

ive patients that were detected high levels of EBV DNA, Burkitt’s

lymphoma disease should be considered.
