Insights
Hepatitis C treatment with pegylated interferon and ribavirin caused significant side effects in most patients. Pegylated interferon alpha-2b was linked to more fever and weight loss than alpha-2a.
Area of Science:
- Hepatology
- Pharmacology
- Clinical Medicine
Background:
- Hepatitis C virus (HCV) infection is a major global health concern.
- Pegylated interferon and ribavirin are standard treatments for chronic hepatitis C.
- Understanding treatment-related side effects is crucial for patient management.
Purpose of the Study:
- To compare the side effect profiles of pegylated interferon and ribavirin in hepatitis C patients.
- To evaluate the prevalence and types of adverse events associated with this treatment regimen.
- To identify differences in side effects between pegylated interferon alpha-2b and alpha-2a.
Main Methods:
- A cross-sectional study was conducted at Hospital Mário Covas, Brazil.
- A questionnaire was administered to 340 patients receiving at least one dose of medication.
- Data on reported side effects were collected and analyzed.
Main Results:
- A high incidence of side effects was observed, with only 1.2% of patients reporting none.
- Common side effects included fatigue (82.9%), arthralgia/myalgia (76.8%), and weight loss (71.8%).
- Pegylated interferon alpha-2b was associated with a higher average number of symptoms (8.01) compared to alpha-2a (7.50), with statistically significant differences in fever and weight loss.
Conclusions:
- Hepatitis C treatment with pegylated interferon and ribavirin is associated with substantial morbidity.
- Pegylated interferon alpha-2b demonstrated a higher prevalence of fever and weight loss compared to alpha-2a.
- Close monitoring for adverse events is essential during hepatitis C treatment.
Objective:
To review and compare side effects of hepatitis C treatment with pegylated interferon and ribavirin at the CRIE of the Hospital Mário Covas (Santo André), São Paulo, Brazil, from February 23 to May 5, 2011.
Methods:
Cross-sectional study through questionnaire, with a non-probability sample comprised of 340 patients that had received at least one dose of the medication.
Results:
Side effects presented were fatigue (82.9%), arthralgia and/or myalgia (76.8%), weight loss (71.8%), headache (67.6%), listlessness (65.9%), depression and/or irritability (64.4%), itching (60.6%), fever (59.1%), alopecia (51.5%), dry cough (34.1%), nausea (11.7%), inappetence (11.7%), and dizziness (7.9%). Up to 19 symptoms were reported during treatment. Only four patients (1.2%) did not present side effects. When comparing the types of interferon, it was observed that alpha-2b caused an average of 8.01 symptoms per patient, while alpha-2a was responsible for an average of 7.50 symptoms. Patients using interferon alpha-2b showed more fever, weight loss, headache, arthralgia and/or myalgia, fatigue, listlessness, depression and/or irritability, and dry cough than patients using alpha-2a, who had more alopecia and itching.
Conclusion:
The study shows a high morbidity related to the treatment, as only 1.2% of the patients showed no side effects. In the sample, the pegylated interferon alpha-2b was responsible for higher prevalence of fever and weight loss when compared to alpha-2a, and this was a statistically significant relation (p < 0.05).
