Study of haematological parameters in malaria

Background Malaria   causing   plasmodia   are   parasites   of   blood   and   hence   induce haematological alterations. The haematological changes that have been reported to accompany malaria include anemia, thrombocytopenia and leucocytosis, leukopenia, mild   to   moderate   atypical   lymphocytosis, monocytosis,   eosinophilia   and neutrophilia.

Methods Total hundred smear positive malaria cases were taken and various hematological parameters and biochemical parameters were studied.

Results Out of 100 smear positive cases, P. vivax was positive in 55 cases while P. falciparum was positive in 45 cases. It was seen in 86.67% of falciparum Malaria patients and in 72.72% of vivax Malaria patients. Severe anemia was seen in 9% of patients. Normocytic normochromic blood picture was the most common type in anaemic patients (51.89%). Thrombocytopenia was seen in 71% of the patients. Mild thrombocytopenia was more common and present in 52% of patients while Severe thrombocytopenia was seen in 19% of cases. In falciparum malaria thrombocytopenia was present in 66.66% of the patients while it was present in 74.54% of the patients in vivax malaria. Total Leucocyte Count was normal in 72% of the patients.

Conclusions Various haematological findings can help in early diagnosis of malaria which is essential for timely and appropriate treatment which can limit the morbidity and prevent further complications.
