The aim of my study is to
determine the significance
of thrombocytopenia in malaria.
Patients and Methods.
It was a prospective observational study on
all febrile patients with thrombocytopenia presenting to the allied hospital
Faisalabad during august to November 2017.
Of the total of 75 patients with fever and
thrombocytopenia, patients 41(55per) proved to be suffering from malaria.
Out Of them 29 patients (71per) had falciparum malaria while 12 patients (29per) had vivax
Of these 41 patients, platelet counts ranged between 25,000 and 150,000/dL with
a mean value of 101,000/dL (SD ± 47,500)
and a median of 75,000/dL. Of the 34 patients who were not suffering from malaria, the
counts ranged between 10,000 and 150,000/dL with a mean value of 58,000/dL (SD ± 54,000) and median of
presence of thrombocytopenia may be a predictor of malaria in adult population.
Malaria is usually associated with various degrees of hematological disorder like anemia and thrombocytopenia. Thrombocytopenia is
an early and consistent characteristic of plasmodium falaciparum
and plasmodium vivex malaria (K. Ghosh et al, 2007).
in addition to
their central role in haemostasis, platelets also play their important role in wide range
of immune modulating, inflammatory and
angiogenic factors (S. N. Wickramasinghe et al,
advance studies have suggested that platelets play their vital role in the innate host defense at the
start of a malaria infection. McMorran
and co-workers showed that purified human platelets were able to kill P. falciparum parasites
within erythrocytes in an in
system, an effect that was dependent on platelet activation by adenosine
5′-diphosphate (ADP) (V. D’Acremont et al,
they showed that platelet deficient however the pathogenesis of
thrombocytopenia stays incompletely understood. In falciparum
malaria there is accelerated platelet intake as
evidenced by using shortened survival of radiolabelled platelets (S.
S. Jamal et al., 2008).
The anemia is generally because of varied reasons ranging from hemolysis
to comorbidities like parasitic infections, folate, iron, and vitamin B12 deficiencies in endemic regions, anti malaria and similarly complicated by
way of the coexistence of thalassemia and
different haemoglobinopathies (T. S. Faseelaet al.,
thrombocytopenia are the maximum frequent malaria-related hematological
complications (Rasheed et al., 2008).
response is, in any case, additionally fantastically blunted, and there is
decreased platelet depend and every so often diminished WBC considers
appropriately. Thrombocytopenia is a totally not surprising association of
jungle fever. in the past it move toward becoming thought that intestinal
sickness isn’t regularly connected with clinical elements of thrombocytopenia like draining
issue and is normally an accidental situating on blood testing. Most recent
logical confirmations have negated this account. it’s far relevant that the
situating of thrombocytopenia in influenced individual can be a showing for a
concentrated post into the blood spread to preclude intestinal sickness in
light of the fact that the motive.This actuality is particularly essential
inside the work up for thrombocytopenia in febrile patients. Thrombocytopenia
might be identified with draining inclination that is one of the urgent extreme
indications of P. falciparum jungle fever. The nearness of thrombocytopenia in
intense febrile vacationers getting backfrom tropical zones has come to be an
extraordinarily tricky logical marker for intestinal sickness visualization(G.
E. Grau et al.,2003).
Some of observational research have showed the association of
thrombocytopenia to malaria but till date the reason of thrombocytopenia is poorly understood. The
speculated mechanisms main to
thrombocytopenia are coagulation disturbances, splenomegaly, bone marrow alterations, antibody-mediated platelet destruction,
oxidative pressure, and the function of platelets as cofactors in triggering
excessive malaria.In an animal version of
cerebral malaria, platelet’s function has
been implicated. In autopsy research of kids loss
of life of cerebral malaria, clumps of
platelets with or without infected RBC’s were determined in
the mind capillaries.The platelet counts generally are normalized fast in a matter of few weeks whilst malaria
is handled effectively (A. Pain et al.,
