==Overview==
==Overview==
[[Thrombocytopenia]] has a broad range of potential causes. While a good [[History and Physical examination|history and physical examination]] can be helpful to diagnose some of these causes such as drug-induced thrombocytopenia, they usually don't suffice and further evaluation is often needed. There are also some useful points that may guide the [[physician]] to an appropriate [[diagnosis]]. For example, [[asymptomatic]], isolated [[thrombocytopenia]] most probably suggests [[Idiopathic thrombocytopenic purpura|ITP]], while [[thrombocytopenia]] in critically ill, hospitalized patients is usually suggestive of [[Iatrogenesis|iatrogenic]] causes (eg. [[dilution]]), [[platelet]] consumption, [[bone marrow suppression]] from [[infection]]/[[sepsis]], or even [[drug-induced thrombocytopenia]]. One should consider however, that a wide variety of other conditions such as [[autoimmune disorders]], [[nutrient]] deficiencies, [[thrombotic microangiopathies]] could all as well cause [[thrombocytopenia]].

'''''Criteria for Rejecting the Diagnosis'''''
* Firm alternate diagnosis to infective endocarditis
* Resolution of infective endocarditis syndrome in under 4 days on antibiotics
* '''''Does not meet the criteria below:'''''
 
'''''Criteria for Definitive Endocarditis'''''
 
The Duke Clinical Criteria for definitive infective endocarditis require either:
* Two major criteria

* One major and three minor criteria
: OR
* Five minor criteria
 
=== Major Criteria ===
'''1. Positive Blood Culture for Infective Endocarditis'''
: '''A. Typical microorganism consistent with infective endocarditis from 2 separate blood cultures, as noted below:'''
:: ☑ [[Viridans streptococci]], ''[[Streptococcus bovis]]'', '''or'''
:: ☑ [[HACEK]] group, '''or'''
:: ☑ Community-acquired ''[[Staphylococcus aureus]]'' or [[enterococci]], in the absence of a primary focus
: OR
: '''B. Microorganisms consistent with infective endocarditis from persistently positive blood cultures defined as:'''
:: ☑ 2 positive cultures of blood samples drawn >12 hours apart, '''or'''
:: ☑ All of 3 or a majority of 4 separate cultures of blood (with first and last sample drawn 1 hour apart)
'''2. Evidence of endocardial involvement'''
: '''Positive echocardiogram for infective endocarditis defined as:'''
:: ☑ Oscillating intracardiac mass on valve or supporting structures, in the path of regurgitant jets, '''or'''
:: ☑ On implanted material in the absence of an alternative anatomic explanation, '''or'''
:: ☑ Abscess, '''or'''
:: ☑ New partial dehiscence of prosthetic valve
: OR
:: ☑ New valvular regurgitation (worsening or changing of preexisting murmur not sufficient)
'''Minor criteria:'''
: ☑ Predisposition: predisposing heart condition or [[intravenous drug use]]
: ☑ [[Fever]]: temperature > 38.0° C (100.4° F)
: ☑ Vascular phenomena: major arterial emboli, septic pulmonary infarcts, [[mycotic aneurysm]], [[intracranial hemorrhage]], [[Conjunctival hemorrhage|conjunctival hemorrhages]], and [[Janeway lesions]]
: ☑ Immunologic phenomena: [[glomerulonephritis]], [[Osler's nodes]], [[Roth spot|Roth spots]], and [[rheumatoid factor]]
: ☑ Microbiological evidence: positive [[blood culture]] but does not meet a major criterion as noted above (see footnote) or serological evidence of active infection with organism consistent with infectious endocarditis
: ☑ Echocardiographic findings: consistent with infectious endocarditis but do not meet a major criterion as noted above
: '''Footnote:''' It should be noted that the criteria exclude single positive cultures for [[coagulase-negative staphylococci]], diphtheroids, and organisms that do not commonly cause endocarditis.

Overview

Thrombocytopenia has a broad range of potential causes. While a good history and physical examination can be helpful to diagnose some of these causes such as drug-induced thrombocytopenia, they usually don't suffice and further evaluation is often needed. There are also some useful points that may guide the physician to an appropriate diagnosis. For example, asymptomatic, isolated thrombocytopenia most probably suggests ITP, while thrombocytopenia in critically ill, hospitalized patients is usually suggestive of iatrogenic causes (eg. dilution), platelet consumption, bone marrow suppression from infection/sepsis, or even drug-induced thrombocytopenia. One should consider however, that a wide variety of other conditions such as autoimmune disorders, nutrient deficiencies, thrombotic microangiopathies could all as well cause thrombocytopenia.
