Summary
Hepatitis A (HA) infections can present as prolonged or relapsing (polyphasic) illnesses in adults. These forms, while benign, require extended recovery periods, impacting patient management and healthcare resource utilization.
Area of Science:
- Hepatology
- Infectious Diseases
- Clinical Medicine
Background:
- Hepatitis A (HA) is a significant public health concern.
- Understanding diverse clinical presentations of HA is crucial for effective patient care.
- Protracted and polyphasic HA infections represent less common but important disease courses.
Purpose of the Study:
- To determine the incidence of polyphasic and protracted Hepatitis A (HA) infections in adults.
- To describe the clinical characteristics and outcomes of these specific HA infection forms.
Main Methods:
- Retrospective analysis of 297 adult HA patients.
- Evaluation of clinical course, including relapses and complications.
- Assessment of recovery time and readmission rates.
Main Results:
- 12.5% of patients exhibited a polyphasic (relapsing) HA course.
- 8.4% of patients had a protracted HA infection.
- Symptomatic relapse rates were 51% for polyphasic and 56% for protracted HA.
- Cholestatic pattern observed in 1% of patients; 3% required readmission.
- Complete recovery took up to six months in some cases.
Conclusions:
- Polyphasic and protracted HA infections occur in a notable percentage of adult patients.
- These forms are associated with frequent symptomatic relapses and prolonged recovery.
- While outcomes are benign, the clinical course necessitates awareness and potentially extended supportive care.
