Hyperproteinemia
Hyperproteinemia is the state of having overly high levels of protein in the blood. This can occur due to monoclonal gammopathies such as multiple myeloma and after intravenous immunoglobulin has been given. It can result in a falsely low appearing sodium level (hyponatremia). Causes Increases in certain proteins that are typically present in relatively low concentrations, such as acute phase reactants and polyclonal immunoglobulins caused by inflammation, late-stage liver disease, and infections, can result in mild hyperproteinemia. Normal total protein levels are not sufficient to rule out multiple myeloma or other malignant paraproteinemias, but they may also be the cause of moderate-to-marked hyperproteinemia. To determine the reason behind the elevated serum total protein, a serum protein electrophoresis should be carried out. The plasma protein level may increase due to dehydration from blood loss of fluids (severe vomiting and diarrhea). 1. Physiological causes: * Sta ...

Serum Protein Electrophoresis
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma, a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy between a low albumin and a relatively high total protein. Unexplained bone pain, anemia, proteinuria, chronic kidney disease, and hypercalcemia are also signs of multiple myeloma, and indications for SPE. Blood must first be collected, usually into an airtight vial or syringe. Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein components into five major fract ...

Paraproteinemias
Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia. The most common form of the disease is monoclonal gammopathy of undetermined significance. Causes Causes of paraproteinemia include the following: * Leukemias and lymphomas of various types, but usually B-cell non-Hodgkin lymphomas with a plasma cell component. ** Myeloma ** Plasmacytoma ** Lymphoplasmacytic lymphoma * Idiopathic (no discernible cause): some of these will be revealed as leukemias or lymphomas over the years. ** AL amyloidosis Diagnosis These are characterized by the presence of any abnormal protein that is involved in the immune system, which are most often immunoglobulins and are associated with the clonal proliferation of lympho ...

Hypoproteinemia
Hypoproteinemia is a condition where there is an abnormally low level of protein in the blood. There are several causes that all result in edema once serum protein levels fall below a certain threshold. Signs and symptoms The severity of symptoms can vary, but may include: # fatigue and weakness # recurrent infections # brittle nails and dry skin # thinning and breaking hair # mood changes and irritability Causes # Nutritional hypoproteinemia is due to severe limitation of protein intake in the diet. An example of nutritional hypoproteinemia is Kwashiorkor, a type of protein energy malnutrition affecting young children. # Malabsorption, often caused by celiac disease or inflammatory bowel disease # Liver disease can also cause hypoproteinemia by decreasing synthesis of plasma proteins like albumin. # Renal disease like nephrotic syndrome can also result in hypoproteinemia because plasma proteins are lost in the urine. # Sepsis (whole body infection) – macrophages activated i ...

Nephrotic Syndrome
Nephrotic syndrome is a collection of symptoms due to kidney damage. This includes proteinuria, protein in the urine, hypoalbuminemia, low blood albumin levels, hyperlipidemia, high blood lipids, and significant edema, swelling. Other symptoms may include weight gain, feeling tired, and foamy urine. Complications may include blood clots, infections, and high blood pressure. Causes include a number of kidney diseases such as focal segmental glomerulosclerosis, membranous nephropathy, and minimal change disease. It may also occur as a complication of diabetes, lupus, or amyloidosis. The underlying mechanism typically involves damage to the Glomerulus (kidney), glomeruli of the kidney. Diagnosis is typically based on urinalysis, urine testing and sometimes a kidney biopsy. It differs from nephritic syndrome in that there are no red blood cells in the urine. Treatment is directed at the underlying cause. Other efforts include managing high blood pressure, high blood cholesterol, ...

Urine Protein Electrophoresis
Protein electrophoresis is a method for analysing the proteins in a fluid or an extract. The electrophoresis may be performed with a small volume of sample in a number of alternative ways with or without a supporting medium, namely agarose or polyacrylamide. Variants of gel electrophoresis include SDS-PAGE, free-flow electrophoresis, electrofocusing, isotachophoresis, affinity electrophoresis, immunoelectrophoresis, counterelectrophoresis, and capillary electrophoresis. Each variant has many subtypes with individual advantages and limitations. Gel electrophoresis is often performed in combination with electroblotting or immunoblotting to give additional information about a specific protein. Denaturing gel methods SDS-PAGE SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, describes a collection of related techniques to separate proteins according to their electrophoretic mobility (a function of the molecular weight of a polypeptide chain) while in the denatur ...

Protein Losing Enteropathy
Protein losing enteropathy (PLE) is a syndrome in which Blood protein, blood proteins are lost excessively via the gastrointestinal tract, gastrointestinal (GI) tract. It may be caused by many different underlying diseases that damage the lining of the GI tract (Mucous membrane, mucosa) or cause blockage of its Lymphatic system, lymphatic drainage. Signs and symptoms The signs and symptoms of protein losing enteropathy include diarrhea, fever, and general abdominal discomfort. Swelling of the legs due to peripheral edema can also occur; however, if the PLE is related to a systemic disease such as congestive heart failure or constrictive pericarditis, then these symptoms could be due directly to the underlying illness. In severe cases, anasarca, a generalized form of edema, may develop. Causes The causes of protein-losing enteropathy can include GI conditions (among other causes), like the following: Mechanism The pathophysiology of protein losing enteropathy is a result of pla ...

Hypogammaglobulinemia
Hypogammaglobulinemia is an immune system disorder in which not enough gamma globulins are produced in the blood (thus '' hypo-'' + ''gamma'' + '' globulin'' + '' -emia''). This results in a lower antibody count, which impairs the immune system, increasing risk of infection. Hypogammaglobulinemia may result from a variety of primary genetic immune system defects, such as common variable immunodeficiency, or it may be caused by secondary effects such as medication, blood cancer, or poor nutrition, or loss of gamma globulins in urine, as in nonselective glomerular proteinuria. Patients with hypogammaglobulinemia have reduced immune function; important considerations include avoiding use of live vaccines, and take precautionary measures when traveling to regions with endemic disease or poor sanitation such as receiving immunizations, taking antibiotics abroad, drinking only safe or boiled water, arranging appropriate medical cover in advance of travel, and ensuring continuation of ...

Multiple Myeloma
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibody, antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, anemia, Kidney failure, renal insufficiency, and infections may occur. Complications may include hypercalcemia and amyloidosis. The cause of multiple myeloma is unknown. Risk factors include obesity, radiation exposure, family history, age and certain chemicals. There is an increased risk of multiple myeloma in certain occupations. This is due to the occupational exposure to aromatic hydrocarbon solvents having a role in causation of multiple myeloma. Multiple myeloma is the result of a multi-step malignant transformation, and almost universally originates from the pre-malignant stage monoclonal gammopathy of undetermined significance (MGUS). As MGUS evolves into MM, another pre-stage of the disease is reached, known as Smouldering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Infection
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasi ...

Hematology
Hematology (American and British English spelling differences#ae and oe, spelled haematology in British English) is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, sickle cell anemia, blood clots (thrombus), other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist. Specialization Physicians specialized in hematology are known as hematologists or haematologists. Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hema ...
