[Cholestatic viral hepatitis: is it an easy diagnosis?]

Area of Science:

• Hepatology
• Virology
• Clinical Diagnostics

Background:

• Acute cholestatic viral hepatitis presents diagnostic challenges, particularly differentiating viral causes.
• Distinguishing between Hepatitis A and non-A, non-B hepatitis requires careful clinical and laboratory evaluation.

Observation:

• Three cases of acute cholestatic viral hepatitis were analyzed: one confirmed Hepatitis A and two presumed non-A, non-B viral hepatitis.
• Laboratory findings included minimal transaminase level fluctuations or rapid declines, contrasting with elevated bilirubin and cholestatic markers.
• One case exhibited prolonged symptoms, raising questions about potential underlying systemic diseases, though Hodgkin's disease was considered unlikely due to atypical laboratory profiles.

Findings:

• Diagnostic difficulties in acute cholestatic viral hepatitis are discussed, emphasizing methods for accurate diagnosis.
• The study highlights unique laboratory patterns: slight or abrupt transaminase changes alongside increasing bilirubin and cholestatic parameters.
• A prolonged case suggests the need to consider occult systemic diseases, even when viral hepatitis is suspected.

Implications:

• Accurate diagnosis of acute cholestatic viral hepatitis is crucial for appropriate patient management.
• Understanding atypical laboratory findings aids in differentiating viral hepatitis from other conditions.
• Further investigation may be warranted in prolonged cases to rule out coexisting systemic diseases.
