Morphology of acute inflammation Exudative inflammation is characterized by prevailing of exudation and development of exudates in tissue and body cavities. 14. Morphological types of exudative inflammation (according to character of exudates and prevailing location): • Serous, when the fluid exudate resembles serum or is watery. Pleural effusion. 1. A pleural effusion is an abnormal collection of fluid in the pleural space resulting from excess fluid production or decreased absorption or both. It is the most common manifestation of pleural disease. Hemothorax is blood in plueral space . Chylothorax is chyle (lymph+fat) in pleural spcae. Empyema is pus in plueral space

Transudate vs exudate Transudate. Transudative pleural effusions are defined as effusions that are caused by factors that alter hydrostatic pressure, pleural permeability, and oncotic pressure.. Conditions associated with transudative pleural effusions include:. Congestive heart failure; Liver cirrhosis; Severe hypoalbuminemi . This is the key difference between exudates and transudate
Determination of transudate versus exudate source of pleural effusion. Fluid is exudate if one or more of the following Light's criteria is present: Mnemonic: 5,6,7 PLR. (Like pleura): Effusion protein/serum protein ratio greater than 0.5.. The main difference between transudate and exudate pleural effusion is that the transudate pleural effusion results in a filtrate of clear fluid with a low protein and cell content. It is due to the increased capillary hydrostatic pressure and/or decreased capillary oncotic pressure. But, on the other hand, the exudate pleural effusion results in a cloudy fluid with a high protein and cell. Transudate • Exudates • Lab analysis: Gross exam, cell count, etc. • Differential: PMN, Lymph, Mono, etc. • Cells unique to the lungs: Mesothelial cells • RBCs and WBCs: are limited, if increased without traumatic tap ----- indicates infarction • Cytology exam: useful in identifying malignancy or abnormal morphological cells Effusions may be classified as a pure transudate, a modified transudate, an exudate, a hemorrhagic effusion, or a neoplastic effusion. Exudates may be subdivided into septic or non-septic exudates. The classification of these fluids is based on 3 parameters; total protein, cell counts, and cytologic appearance. A refractometer i
The first step in the evaluation of patients with pleural effusion is to determine whether the effusion is a transudate or an exudate. An exudative effusion is diagnosed if the patient meets Light. Transudate: Exudate: Main causes ↑ hydrostatic pressure, ↓ colloid osmotic pressure: Inflammation-Increased vascular permeability: Appearance: Clear: Cloudy: Specific gravity < 1.012 > 1.020 Protein content < 2.5 g/dL > 2.9 g/dL fluid protein considered as transudate, the difference of albu-min concentration between serum and effusion is greater than 1.2mg/dl, then the effusion is diag-nosed as transudate. The amount of LDH present in the pleural ﬂuid is a rough indicator of the extent of pleural inﬂammation and is useful in assessing treatment outcomes.

1. The most commonly ordered ascitic fluid tests are shown in Table 13.2.. 2. The serum-ascites albumin gradient (SAAG) is necessary to determine if a patient's ascites is due to portal hypertension. . Calculation of SAAG is performed by measuring the serum albumin and ascitic fluid albumin concentrations simultaneously and then subtracting the ascitic fluid albumin from the serum albumin Exudate effusions: Occur during inflammatory processes that result in damage to blood vessel walls, body cavity membrane damage, or decreased reabsorption by the lymphatic system. Examples include infections, inflammations, hemorrhages and malignancies.

Acidosis Pleural fluid acidosis is found in complicated pleural. . Transudate and exudate are two different types of fluids that are secreted in the body in reaction to different pathologies. Transudates result from an imbalance in oncotic and hydrostatic pressures. These are usually ultrafiltrates of plasma. Exudates are the result of inflammation Pleural fluid puncture (pleural tap) enables the differentiation of a transudate from an exudate, which remains, at present, the foundation of the further diagnostic work-up. When a pleural effusion arises in the setting of pneumonia, the potential devel- opment of an empyema must not be overlooked. Lung cancer is the most common cause of. an exudate, while a difference greater than 1.2 g/dL indicates a transudate.17 A low concen-tration of cholesterol in the pleural fluid may also be more accurate in classifying this fluid as a transudate. If a pleural effusion is likely to be a transu-date, initial laboratory tests can be limited to levels of protein, cholesterol, and lactate dehy
Causes of pleural fluid transudates and exudates. Pleural effusion: main causes and features Light's criteria for distinguishing pleural transudate from exudate Pleural fluid is an exudate if one or more of the following criteria are met: Pleural fluid protein:serum protein ratio > 0.5. Pleural fluid LDH:serum LDH ratio > 0. 1. General measures: bed rest,propped up position. ,oxygen inhalation, symptomatic support, • Pleurocentesis: removal of fluid from pleural space. • Chest tube drainage for empyema. 2.Specificic treatment:if TB- antituberculae drugs. if pneumonia: aspiration followed by antibiotics. If malignant effusion: intercoastal chesttube drainage Pleural Effusion. Pleural effusions are accumulations of fluid within the pleural space. They have multiple causes and usually are classified as transudates or exudates. Detection is by physical examination and chest x-ray; thoracentesis and pleural fluid analysis are often required to determine cause Thus, CHF-related exudates were identified in only 12 patients, and in 4 of these patients the exudates could be explained by RBC contamination of the pleural fluid. The clinical presentation of patients with CHF-associated exudates was similar to that of CHF patients with transudates A brief overview of ascitic fluid analysis, including how to interpret ascitic fluid results and how to differentiate between an exudate and a transudate.

exudates; transudates; pleural effusions; Pleural effusions develop in thoracic or systemic diseases and, based on their underlying pathophysiology, they are classified into transudates or exudates.1 2 They are termed exudates if the pleural fluid to serum ratio of total protein (TPR) is >0.5, the pleural fluid absolute lactic dehydrogenase (FLDH) level is >200 IU/l, or the pleural fluid to. . Transudate. Total protein, albumin and LDH level will be low. Value of SAAG above 1.1 g/dL is considered evidence of a transudate condition. Exudate.

Common causes can then be actively sought and treated; Use Light's criteria is moderately sensitive for differentiation, further tests are then required to further define the exudate; Pleural fluid from thoracocentesi Analysis of the pleural fluid should be done to figure out if the cause of the pleural effusion is an exudate or transudate. Light's criteria is a type of criteria that can diagnose if the effusion is an exudate or transudate. Exudate effusions are commonly caused by malignancies, autoimmune diseases, pancreatitis, and post- myocardial. Pleural effusions are a common medical problem with more than 50 recognised causes including disease local to the pleura or underlying lung, systemic conditions, organ dysfunction and drugs.1 Pleural effusions occur as a result of increased fluid formation and/or reduced fluid resorption. The precise pathophysiology of fluid accumulation varies according to underlying aetiologies
Transudate versus exudate. Transudates accumulate when vascular hydrostatic pressures increase, oncotic pressures decrease, or both occur simultaneously. Congestive heart failure is one of the most common causes of transudates. Transudates are also associated with hypoalbuminemia, nephritic syndrome, and peritoneal dialysis In this prospective study of 70 patients with pleural effusion, the underlying disease could be identified in 62 cases. By predefined criteria, 31 of these effusions were classified as transudates and 31 as exudates. Pleural fluid protein content, LDH activity and cholesterol level were measured to investigate their utility in differentiating the exudates from the transudates

Transudates vs exudates. There are many causes of pleural effusion that are broadly split into transudates and exudates. This categorisation relies upon the biochemical analysis of aspirated pleural fluid 5: transudate. protein concentration <30 g/L absolute; total protein fluid:serum ratio <0.5; lactate dehydrogenase (LDH) <20 IU/L; LDH fluid.
Pleural effusions are generally classified as transudates or exudates, based on the mechanism of fluid formation and pleural fluid chemistry. Transudates result from an imbalance of oncotic and hydrostatic pressures, whereas exudates are the result of inflammatory processes of the pleura and/or decreased lymphatic drainage Effusions were classified as transudate or exudate using Light's criteria, and serum-effusion albumin gradient criterion in some doubtful cases of exudates 9-11. Definitions The specific aetiology of transudative effusions (congestive heart failure, liver cirrhosis and nephrotic syndrome) was based on clinical and laboratory data, as well as.

It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to. • Straw: serous effusion (clear = transudate; cloudy = exudates) • Bloody: trauma, malignancy, haemorrhagic pancreatitis, perforated peptic ulcer • Turbid: SBP, perforated viscus • Chylous (milky): malignancy, lymphoma, tuberculosis, parasitic Serum-ascites albumin gradient (SAAG This is a descriptive study carried out in Khartoum state hospitals during the period from May 2012 to April 2014. The study aimed to evaluate the diagnostic role of the pleural effusion/serum (CHOL, LDH, and protein) ratios in the differentiation between exudate and transudate pleural effusion. As a part of the investigation, 135 serum and pleural effusion samples were collected from patients.
. Causes of pleural effusion Can be divided into [ In this case, the LDH is less than 2/3 the upper limit of normal for serum, the protein ratio is 0.33 and the LDH ratio is 0.4. Therefore, this effusion should be classified as a transudate. You should be aware that Light's criteria will misclassify transudates as exudates in 15-30% of cases Determining if the increased fluid is transudate or exudate is important because it helps narrow down the possible causes of pericardial fluid buildup. Healthcare practitioners and laboratorians use an initial set of tests, including cell count, protein or albumin level, and appearance of the fluid, to distinguish between transudates and exudates Inflammation and Tissue Repair PTAP-130.

The criteria of Light et al. correctly classified 41 exudates (95%) and 3 transudates (38%), whereas PZE correctly classified 43 exudates (100%) and 4 transudates (50%).The criteria of Light et al. failed to identify an exudate attributable to pneumonia.PZE clearly shows an α-2 band and a γ band. The patient had a pleural/serum total protein ratio of 0.33, a pleural fluid LDH of 99 U/L, and. Compared to other methods that classify the ascites fluid in transudate or exudate, the SAAG is considered more accurate. There are three pieces of information required by the SAAG calculator: Serum concentration of albumin - measured in g/dL or g/L. This represents around 50% of the protein in the blood and is produced by the liver Pleural effusions in animals were initially classified as transudates or exudates based on pleural effusion: specific gravity, total protein concentration (TPp) and total nucleated cell count (TNCCp). 11 As in these two groups these parameters were often overlapping, Perman introduced the modified transudate. 12 This was defined as having a similar TPp and TNCCp to an exudate but formed.

Physiotherapy For Pleural Effusion. The area between the layers of tissue that line the lungs and the chest cavity, known as the pleural space, can get filled with either transudate or exudate forms of fluid. Transudate is usually composed of ultra-filtrates of plasma due to an imbalance in vascular hydrostatic and oncotic forces in the chest. A transudate contains Less than 100/ mm3cells, whereas an exudate usually contains more than1000/ mm3 cells. If Cells count between 100 and 1000 / mm3 access other fluid parameters. III.

and intravenous infusions. In clinical practice the majority of effusions are exudates or transudates. The pleura is usually normal in the presence of a transudate but generally abnormal in the context of an exudative effusion. Traditionally, the distinction between a transudate and an exudate has been based on estimation of specific gravity. It is carried out with purulent-inflammatory processes to eliminate exudate, transudate, blood and air. Kits for pleural puncture. Pharmacies sell ready-made kits that contain everything you need to conduct a puncture. The base of the kit is represented by a syringe and needles. The volume of syringes and the diameter of the needles vary, so.

Analysis of cell count, protein concentra - tion, and specific gravity will determine if the fluid is a transudate, a modified transudate, or an exudate (see thetable Guidelines to Distinguishing Transudates and Exudates, Part IV).Cells should be enumerated manually or by elec (SAAG). Gradients of <11g/L indicate an exudate and diuretics are less likely to be helpful in these patients. Portal hypertension is most commonly associated with massive hepatic metastases or cirrhosis.

Pleural effusion may be classified according to composition of pleural fluid by Light's criteria into two subtypes: exudate and transudate. An increase in plasma osmotic pressure or elevated systemic or pulmonary hydrostatic pressure are alterations that lead to the formation of transudate. In contrast, an exudate results from inflammation and. Thoracentesis or pleural tap, is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall to remove excess fluid, known as a pleural effusion, from the pleural space to help you breathe easier. Normally the pleural cavity contains only a very small amount of fluid Categorization of the fluid as a transudate or exudate simplifies the differential diagnosis, because conditions associated with PF formation tend to cause effusions of one of these types. Light's three-criteria rule has been the traditional approach for identifying exudative effusions ( Table 76-1 ) The evidence-based guideline for the evaluation of unilateral pleural effusions published in 2010 by the British Thoracic Society is useful. 1 However, there is a paucity of data to guide decision-making in many areas. This article provides a pragmatic approach to the evaluation of a patient with pleural effusion, based on the evidence gathered.
Ascitic fluid can accumulate as a transudate or an exudate. Amounts of up to 25 liters are possible. Roughly, transudates are a result of increased pressure in the portal vein (>8 mmHg, usually around 20 mmHg ), e.g. due to cirrhosis, while exudates are actively secreted fluid due to inflammation or malignancy. As a result, exudates are high. Biochemically, effusions can be either an exudate or a transudate. Traditionally, a protein of > 30 g/l indicates an exudative effusion, whereas a protein of < 30 g/l indicates a transudate. However, this is never absolute and as a result, the use of Light's criteria for protein levels between 25 and 35 g/l is recommended ( 1 , 6 ) ( Table 3 ) Mixed inflammatory cells increase in number as a transudate becomes modified and are present in large numbers in an exudate. Mesothelial cells would be expected in this type of sample, and it can therefore be useful to look for a second population when checking for neoplasia Approach to the Patient with Ascites Differential Diagnosis Ascites refers to the pathologic accumulation of fluid within the peritoneal cavity. It is important to establish a cause for its development and to initiate a rational treatment regimen to avoid som
Introduction. Pleural fluid is classically classified as a transudate or an exudate, which helps in determining the cause of pleural effusions. The criteria of Light et al are used as a first step to differentiate transudates from exudates in the workup of patients with pleural effusion. 1 However, these criteria have some limitations, especially in patients with heart failure and taking. Transudate fluid indicates a systemic origin, one in which a part of the body, usually the heart, liver, or kidney, is creating an overall imbalance of the fluids of the body. Exudate fluid indicates there is a problem around or in the lungs such as a bacterial or viral infection, an embolism , or cancer, and further tests are done to get a. Transudate ¯ 7.
