Number of platelets

While taking gold compounds the patient is monitored closely for thrombocytopenia (abnormally low numbers of platelets in the blood). The primary health care provider orders frequent blood studies (usually once a month or more frequently). 

A number of laboratory tests are available to measure the phases of hemostasis described above. The tests include platelet count, bleeding time, activated partial thromboplastin time (aPTT or PTT), prothrombin time (PT), thrombin time (TT), concentration of fibrinogen, fibrin clot stabifity, and measurement of fibrin degradation products. The platelet count quantitates the number of platelets, and the bleeding time is an overall test of platelet function. aPTT is a measure of the intrinsic pathway and PT of the extrinsic pathway. PT is used to measure the effectiveness of oral anticoagulants such as warfarin, and aPTT is used to monitor heparin therapy. The reader is referred to a textbook of hematology for a discussion of these tests. 

For a short description of the aims of experimental concentration cycling with respect to citraconic acid formation, see [13]. It is also demonstrated there that the response to rectangular concentration pulses for a given reactor configuration of a multi-channel-stack micro reactor can be improved by increasing the number of platelets and channels (while reducing their diameter). Such behavior was shovm for an incompressible fluid, i.e. is not solely related to the above-mentioned reaction.

Differential Diagnosis Thrombocytopenia (a condition in which there is an abnormally small number of platelets in the circulating blood) and an elevated aspartate aminotransferase (AST) may provide a clue to suggest CCHF is the culprit in the febrile (denoting or relating to fever) patient seen early in the course of infection. Other viral hemorrhagic fevers, meningococcemia, rickettsial diseases, and similar conditions may resemble full-... 

Therapy, to be effective, depends upon administration of an adequate number of platelets, generally 5 X 10 in a 70 kg man or a 60 kg woman given over 15 minutes - with suitable adjustment for body surface area in children. It is mandatory that the increment is calculated and the duration of response be documented at 24 hours. The optimum practice is to relate the number infused to changes achieved in the patient by means of the corrected count index. This step anticipates the emergence of resistance that limits the value of repeated transfusions. Occasional allergic reactions have to be blocked by premedication with an intravenous injection 100 mg of hydrocortisone, 12.5 mg of phenergan and 1 g of paracetamol...

Large doses of glucocorticoids have been associated with the development of peptic ulcer, possibly by suppressing the local immune response against Helicobacter pylori. They also promote fat redistribution in the body, with increase of visceral, facial, nuchal, and supraclavicular fat, and they appear to antagonize the effect of vitamin D on calcium absorption. The glucocorticoids also have important effects on the hematopoietic system. In addition to their effects on leukocytes, they increase the number of platelets and red blood cells.

Interleukin-11 is the first growth factor to gain FDA approval for treatment of thrombocytopenia. It is approved for the secondary prevention of thrombocytopenia in patients receiving cytotoxic chemotherapy for treatment of nonmyeloid cancers. Clinical trials show that it reduces the number of platelet transfusions required by patients who experienced severe thrombocytopenia after a previous cycle of chemotherapy. Although IL-11 has broad stimulatory effects on hematopoietic cell lineages in vitro, it does not appear to have significant effects on the leukopenia or neutropenia caused by myelosuppressive chemotherapy. Interleukin-11 is given by subcutaneous injection at a dose of 50 g/kg/d. It is started 6-24 hours after completion of chemotherapy and continued for 14-21 days or until the platelet count passes the nadir and rises to > 50,000 cells/ L.

Suboptimal platelet response to clopidogrel may be due to an increased number of platelet P2Y 2 receptors or polymorphism of platelet receptors. Genetic polymorphisms of platelet GPIIb/llla, GPIa/lla, or P2Y 2 receptors have been reported to affect platelet function and may influence dopidogrel response variability (103-105). Recently, it was reported that an increased percentage of patients with peripheral arterial disease have the P2Y 2 receptor H2 haplotype (104). However, in another study, the relation of this haplotype to clopidogrel responsiveness could not be demonstrated (105). Since the relation... 

Investigation of coagulation is more easily carried out in vitro. Although the two processes are similar, it is necessary to be cautious in comparing in vivo and in vitro mechanisms. The clot formed in a test tube is different from that formed in the vascular system. Coagulation in vitro consists of a fibrin net in which there exist white and red cells and a small number of platelets. In vivo, the clots consist of large amorphous masses of platelets surrounded by white cells and very few red cells. 

Approx. 50-100 xl blood are collected into potassium-EDTA-coated tubes at times -1, 1 and 2 min (guinea pigs and mice) or 5, 10 and 15 min (rabbits) following the injection of the inducer. The number of platelets and leukocytes is determined within 1 h after withdrawal in 10 xl samples of whole blood using a microcellcounter suitable for blood of various animal species.
