Brief HPI: A middle-aged female with no known medical history is brought to the emergency department. Differential diagnosis and management of thrombocytopenia in childhood. The purpose of this article is to provide the reader with a firm knowledge of the major causes of thrombocytopenia and their treatments, and to form a broad differential diagnosis, so that it will be clearer when to consider a rare etiology Differential Diagnosis of Thrombocytopenia Joel S. Bennett Charles S. Abrams Thrombocytopenia is encountered frequently in clinical practice, engendering substantial and appropriate concern about its etiology and the consequent risk and prevention of bleeding The differential diagnosis of immune thrombocytopenia (ITP) has evolved in recent years, explains Howard A. Liebman, MD. Revised guidelines were recently released describing that the pathway of.

When evaluating the production of platelets in the bone marrow, IPF helps in the differentiation between thrombocytopenia caused by decreased production and thrombocytopenia caused by increased destruction / consumption, contributing to avoid an invasive bone marrow biopsy The differential diagnosis for a patient with new thrombocytopenia is broad and includes primary bone marrow disorders, chronic liver disease, infection, drug-related adverse effects, occult malignancy and autoimmune/rheumatologic conditions. Epidemiology. The causes of thrombocytopenia are diverse, making epidemiological generalisations difficult

The differential diagnosis for a patient with new thrombocytopenia is broad and includes primary bone marrow disorders, chronic liver disease, infection, drug-related adverse effects, occult malignancy and autoimmune/rheumatologic conditions Nevertheless, patients with severe thrombocytopenia can present to the emergency department with mucocutaneous bleeding or internal hemorrhage. Isolated thrombocytopenia has a limited differential diagnosis . The 2 most prevalent etiologies are ITP and drug-induced thrombocytopenia (DITP) Thrombocytopenia is defined as a platelet count of less than 150 × 10 3 per μL. It is often discovered incidentally when obtaining a complete blood count during an office visit. The etiology.. Following are differential diagnoses for patients presented with thrombocytopenia.*. Breed-associated inherited macrothrombocytopenia. Cavalier King Charles spaniels. Norfolk and cairn terriers. Identified sporadically in: Bichons frises. Boxers Thrombocytopenia should be diagnostically evaluated as early as possible in pregnancy, so that the obstetrical management can be accordingly planned to minimize harm to the mother and child.

Thrombocytopenia may be associated with a variety of conditions, with associated risks that may range from life-threatening bleeding or thrombosis (eg, in heparin-induced thrombocytopenia [HIT]) to no risk at all. At the time of initial presentation, the cause may be unclear and the direction of the platelet count trend may not be known The differential diagnosis of thrombocytopenia as an isolated abnormality (that is, unaccompanied by hemolytic anemia or bone marrow pathology affecting all 3 cell lines) includes: V iral infections. I mmune-mediated platelet destruction. C ongenital diseases. G estational thrombocytopenia. S.

For example, if you have heparin-induced thrombocytopenia, your doctor can prescribe a different blood-thinning drug. Other treatments might involve: Blood or platelet transfusions. If your platelet level becomes too low, your doctor can replace lost blood with transfusions of packed red blood cells or platelets. Medications The differential diagnosis of thrombocytopenia in pregnancy is based on the patient's personal and family history, drug history, and dietary habits, the physical findings (e.g., hematomas, petechiae), and the findings of basic laboratory tests The differential diagnosis of gestational thrombocytopenia. Gestational thrombocytopenia arises in 5-8% of all pregnancies and is the most common form of thrombocytopenia in pregnancy.

Main tools for the diagnosis of thrombocytopenia are complete blood count and peripheral blood smear when the amount, size and form of thrombocytes are thoroughly evaluated. For the differential diagnosis of thrombocytopenia it is important to assess the onset of it, blood clotting difficulties before the pregnancy and family history A diagnosis of ITP is mostly based upon excluding other causes of thrombocytopenia, but platelet-associated antibodies can also be determined to support an immune mechanism for thrombocytopenia. Therapy of thrombocytopenia is mostly dependent on the underlying cause and severity of clinical signs of bleeding rather than the actual platelet count Current diagnostic criteria for Immune ThrombocytoPenia (ITP) are mainly based on the presence of low numbers of platelets, excluding other multiple causes of thrombocytopenia, including immunodeficiencies, constitutional or acquired thrombocytopenia, hypersplenism and clonal hematological disorders such as MDS, disorders lymphoproliferative and acute myeloid leukemia (AML), among others Introduction. Among the studies that evaluate the usefulness of platelet-derived indices for the differential diagnosis of the causes of thrombocytopenia, some can be found that show how mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR) have a good diagnostic correlation when compared to findings from the study of bone marrow symptoms of localized infection, non-specific symptoms include fever or shivering, dizziness, nausea and vomiting, muscle pain, feeling confused or disoriented; may be history of risk factors e.g. immunosuppression, pregnancy or postpartum period, frailty, recent surgery or invasive procedures, intravenous drug use or breach of skin integrit

Autoimmune heparin-induced thrombocytopenia (HIT) is a rare sequelae of COVID-19 infection. Treatment for spontaneous HIT is argatroban, a highly selective direct thrombin inhibitor. Differential diagnosis of thrombocytopenia in the setting of COVID-19 includes ITP, TTP, DIVC and drug-induced thrombocytopenia Autonomous thrombocytosis (AT) Accounts for 15% of cases. A primary problem that results from myeloproliferative disorders or myelodysplastic syndromes, such as essential thrombocytopenia or polycythemia vera. Complications, such as bleeding and/or thrombosis, are more likely with AT than with RT so it is clinically important to differentiate. DIFFERENTIAL DIAGNOSIS. When a patient presents to a healthcare provider, the purpose of employing differential diagnosis is to narrow an indefinite number of possible diagnoses to a finite scope of diagnoses that can be either confirmed or ruled out through observation, measurement, and treatment outcomes bleeding disorders. In thrombocytopenia, the peripheral smear and platelet count are very important. Large platelets suggest peripheral destruction while small platelets are more indicative of a problem with platelet production.
