Introduction: Thrombocytopenia is a common condition seen in clinical practice. A wide range of
etiologies and variation in clinical presentation often pose a challenge in its diagnosis. Early recognition
of thrombocytopenia and its causes can avoid critical bleeding.
Aim: This study aimed to assess etiology and clinicopathological profile of thrombocytopenia in a
tertiary care center.
Materials and methods: Of all patients whose blood samples were received for complete blood count
analysis, 500 patients with thrombocytopenia were included. Blood samples were run in Sysmex XP-100
and PCi 20 fully automated, three-part differential hematology analyzers. Leishman-stained peripheral
blood smears were also studied.
Results: Mild thrombocytopenia (platelet count 60,000-1,50,000/μl) was seen in majority (84.8%) of the
patients followed by moderate thrombocytopenia (platelet count 20,000-60,000/μl) in 10.8% and severe
thrombocytopenia (platelet count <20,000/μl) in 4.4% of the patients The most common cause of
thrombocytopenia was found to be infections (50% patients) followed by chronic liver disease (14.8%
patients), macrothrombocytopenia (10.6% patients), hematological disorders (8.6% patients), gestational
thrombocytopenia (7.8% patients), drug intake (4.4% patients) and chronic kidney disease (1.8%
patients). Among infections, acute febrile illness (nonspecific) was the most (23.2%) common cause
followed by COVID 19 infection (19.4%) and bacterial sepsis (5.4% patients). Four distinct patterns of
platelet histogram in patients with thrombocytopenia were seen.
Conclusion: Similar to most previous studies, infections were the most common cause of
thrombocytopenia in the present study. The present study also highlights two novel entities- suspected
asymptomatic macrothrombocytopenia and Covid-19 infection.
