Viral Hepatitis
Clinics, diagnostics,
treatment and prophylaxis
Asymptomatic form: the specific markers of
infectious agent and proper immunological
changes are exposed only
Sub-clinical form: immunologic, biochemical and
histological changes, however exposed clinical
signs of illness are absent
Non-jaundice form: appears different clinical
symptoms of illness except jaundice
Jaundice form: appears jaundice, which is the
main sign of hepatitis
Fulminant (malignant) form: extremely severe
Duration of hepatitis:
Acute – till 3 months;
Prolonged – from 3 to 6 months;
Chronic – more than 6 months.
Periods of viral hepatitis, with jaundice:
1. Pre jaundice (initial , prodromal);
2. Jaundice or climax of disease;
3. Period of recovery.
Pathologic syndromes of liver
affection
Cytolytic – ↑ ALT, LDG, Cu;
↓ albumins, protrombin
 Mesenchimal-inflammation – ↑ α-, γ globulins, tymol-test
 Cholestasis – ↑ bilirubin, bile acids,
cholesterine, GGTP, alkaline
phosphatase

Variants of initial period:

Asteno-vegetative: general weakness, fatigue,
headache, insomnia, and change in behavior;
Dyspeptic: anorexia, nausea, vomiting, abdominal
pain, diarrhea;
Catarrhal: influenza, feeling of scratching in
throat, hyperemia of conjunctiva and mucus of soft
palate, dry cough, increase of body temperature;
Artharalgic: characterized by pain in joints
without local inflammatory changes;
Mixed

– 6 and more or vice versa decreases);

Quick appearance of jaundice (within some days);
Improvement of self feelings with appearance of
jaundice;
Mild forms are predominant, severe forms occurs
rarely;
Jaundice period persist not more than 1-2 weeks.

Long incubation period (more than 45 days,
maximum – 6 months);
Progressive beginning of disease;
Often arthralgic syndrome in prodromal period (20 –
30 %);
Prurience of skin and urticaria in prodromal period;
Prodromal period often persist more than 2 weeks;
Progressive appearance of jaundice, sometimes 2
weeks and more;
Self feelings do not improve with appearance of
jaundice;
Prolonged and severe jaundice period, less than
during hepatitis A;
9. Often exacerbations, remissions and complications
(reason may be hepatitis D infection);
10. Presence of expressed asthenic syndrome during all
clinical periods of disease, prolonged post hepatic
asthenia, sometime years and more;
11. Possible transformation into chronic hepatitis (in 5 –
15% cases) and then into liver cirrhosis (in 15 – 30%
patients of chronic hepatitis);
12. Hepatitis B often run on background of concomitant
diseases.

or parenteral manipulations, which according to
time are similar to maximum incubation period);
Typical prodromal period;
Presence of hepatic splenomegaly syndrome;

Signs of cholestatic form of viral hepatitis:
Developed pruritis of skin;
Mild intoxication or absent;
Green or grey-green shade of jaundice;
Liver has normal sizes or little enlarged;
Activity of secretary enzymes is elevated in blood
(alkaline phosphates, gammaglutamiltranspeptidase),
quantity of β-lipoproteins, cholesterol and salts of
bile acids;
Don’t present urobilin in urine and stercobilin in
stools;
Little elevation or normal activity of liver cell’s
enzymes;
Prolonged duration – 3-5 months and more.

Liver smell from mouth;
Elevation in body temperature;
Tremors;
Appearance of hemorrhagic syndrome;
Tachycardia;
Decreasing of liver sizes;
Bilirubin-enzymes dissociation;
Elevation of nitrogen products concentration in blood;
Decreasing of prothrombin index <50%;
Appearance of tyrosine and lucien in urine;
Periods of acute hepatic encephalopathy:

Pre-coma 1, 2.
Initial period of precoma (period of precursors);
Finishing period of precoma (partial disorders of
consciousness);
Coma 1, 2.
Superficial coma (loss of verbal contact with kept
reactions on painful irritations);
Deep coma (disappear pain reaction).
Diagnostic
Preliminary diagnosis of viral hepatitis is
based on epidemiological anamnesis
 finding of the development of the disease,
clinical picture, duration of incubation period
 character of prejaundice period
 presence of typical subjective and objective
signs with account of the patients age

Diagnostic
Routine blood test – lymphocytosis,
anemia and leucopenia, ESR is slightly
decreased
 In urine - urobilin and bile pigments
 In blood serum - bilirubinemia (direct
fraction) increasing activity of ALT, ACT,
testifying about the presence of
cytolytic processes in the liver

Diagnostic
Revealing of specific antigens and
antibodies to antigens in the blood
 Discovery of antibodies of class IgM
testifies about acute disease
 Discovery antibodies of other classes
of immunoglobulins testifies about
chronic course of viral hepatitis

immunoglobuline, for others - amizon, mephenamine acid;
Current and final desinfection;
Sanitary control measures;
Active immunization – HAV-Vax;

Parenteral hepatitis (В, С, D)
Use of disposable medical instruments, thorough sterilisation of nonexpendable instruments
Clinical and laboratory examination of blood and organ donors;
Specific prophylaxis - vaccination against B hepatitis HB-Vax, Ingerix-B
