The severity of Cytopenias inuences the
treatment advancements of HCV, leading to a high rate
of morbidity and antiviral therapy discontinuation.

The
need for area-based data on the frequency,
determinants, and risk factors of cytopenias in patients
receiving antiviral therapy for HCV is important for
mapping prevention strategies, improving patient
management, reducing morbidity, and enhancing
treatment outcomes. Routine hematologic tests will
assist health professionals in tracking and identifying
patients at risk, managing treatment regimens, and
allocating resources.

This study aims to assess the
frequency of cytopenias in patients on hepatitis C
therapy after a 12-week follow-up visit at Lady Reading
Hospital in Peshawar (LRH).
METHODOLOGY
This analytical cross-sectional study was conducted at
the Department of Medicine and Gastroenterology,
Lady Reading Hospital (LRH), Peshawar. Ethical
approval was obtained from the Institutional Review
Board of LRH (ERC#156/LRH/MTI). The study was
carried out over a period of six months from 20
th
May
2024 to November 2024. Written informed consent was
obtained from all participants, and the study adhered to
the Declaration of Helsinki. A total of 113 adult
patients diagnosed with chronic hepatitis C and
receiving antiviral therapy were included in the study.
A consecutive non-probability sampling technique was
used to recruit eligible participants who had attended
the medical or gastroenterology outpatient or inpatient
departments after completing 12 weeks of hepatitis C
treatment. Consecutive, non-probability sampling
technique was used. The sample size was calculated
using the WHO sample size formula for proportion
estimation: n = Z² × p × (1−p) / d²
where Z = 1.96 at a 95% condence level, p = 0.32
(expected prevalence of anemia among patients with
hepatitis C based on previous regional studies) and d =
0.08 (margin of error).
10
The calculated sample size was
approximately 113 participants, and all eligible patients
meeting the inclusion criteria during the study period
were included in the nal analysis. These included
patients aged 20-70 years who had conrmed hepatitis
C infection and were under antiviral therapy using
direct-acting antivirals (DAAs) or a conventional
regimen. The study excluded patients with an acute
case of hepatitis C infection, fulminant hepatitis,
cytopenias that had been previously diagnosed before
treatment, hematological malignancies,
myeloproliferative disorders, multiple myeloma,
decompensated chronic liver disease, liver transplant
patients, or hepatocellular carcinoma. Data were
collected using a pre-structured questionnaire
consisting of three sections. The rst section recorded
demographic characteristics, including age, gender,
residence, socioeconomic status, and occupation. The
second section included clinical variables such as
hepatitis C infection duration, treatment regimen, and
sustained virological response (SVR). The third section
included laboratory investigations, including complete
blood count (hemoglobin, white blood cell count, and
platelet count), liver function tests (ALT and AST), and
HCV RNA PCR results. Cytopenias were dened using
standardized laboratory criteria. Anemia was dened
according to World Health Organization thresholds as
hemoglobin <12 g/dL in females and <13 g/dL in
males, while leukopenia and Thrombocytopenia were
defined as white blood cell count <4.0 ×10⁹/L and
platelet count <150 ×10⁹/L respectively, based on
established hematological reference ranges.
Pancytopenia was dened as a simultaneous reduction
in all three cell lines.
11
The 12-week follow-up visit was
conducted to obtain blood samples from eligible
patients. This time point was selected as it corresponds
to the standard assessment of sustained virological
response (SVR12) and allows evaluation of early
hematological adverse eects of antiviral therapy.
Sustained virological response (SVR) was established
by demonstrating HCV RNA levels below the limit of
detection in qualitative and quantitative PCR analysis
following therapy. This study was conducted and
reported in accordance with the STROBE guidelines.
All collected data were entered and analyzed using
Statistical Package for Social Sciences (SPSS) version
25. The quantitative variables, including age, the period
of hepatitis C infection, the period of therapy, and the
laboratory measures, were reported as the mean ±
standard deviation. Categorical variables included
gender, residence, treatment regimen, and the presence
of cytopenias (anemia, leukopenia, Thrombocytopenia,
and pancytopenia), and were also expressed as
frequencies and percentages. Associations between
treatment regimens and study outcomes, including SVR
and cytopenias, were evaluated using the Chi-square
test. The strength of association was assessed using
Cramer’s V. A p-value ≤ 0.05 was considered
statistically signicant.
RESULTS
A total of 113 patients receiving hepatitis C antiviral
therapy were included in the nal analysis. The mean
age of participants was 40.1 ± 9.0 years (95% CI: 38.4-
41.8), indicating a predominantly middle-aged
population. There was a slight male predominance, with
63 (55.8%) males and 50 (44.2%) females. Most
participants resided in urban areas (69.0%), and over
