Repurposing of known drugs with proven safety records is a faster and more efficient way of developing drugs in an outbreak situation, when time is of the essence. Ribavirin and interferon were the most widely used combination in observational studies, and may warrant further investigation (Momattin, H. The optimum dose was determined to be 1-3 mg/kg (or 160-240 mg/day) for a total accumulated dose of 1000-2000 mg. Based on this experience, routine use of corticosteroids is not recommended in patients with 2019-nCoV (Huang, C. Broad-Spectrum Antiviral Agents Ribavirin is a ribonucleoside analogue that is active against some coronaviruses, as well as respiratory syncytial virus and metapneumoviruses. Adverse events, including dose-dependent anemia, arrhythmia, chest pain and dizziness, are a significant concern with ribavirin (Cleri, D. With the possible exception of ribavirin, there is a lack of broad-spectrum antiviral agents. Unlike other infections agents (bacteria, fungi and parasites), viruses share extremely few common features that could be targeted by broad-spectrum agents. The development of broad-range agents requires a better understanding of pivotal virus-host interactions and the identification of targetable host cell proteins involved. Viral Enzyme Inhibitors the process of coronavirus replication is well understood. Several unique steps have been identified as potential targets for antiviral drugs. Nucleoside inhibitors might specifically inhibit viral replication without causing damage to the host cell. Targeted inhibitors of the serine proteases, which are required to activate the viral infectivity of some coronaviruses, may block the later stages of the viral life cycle (Kilianski, A. Following successful preclinical evaluation of lopinavir/ritonavir plus interferon-beta1b, in which significant reductions in mortality were obtained in a marmoset model, clinical evaluation of the combination was recommended (Chan, J. Since the combination of lopinavir and ritonavir was already available in the Wuhan, China hospital where early 2019-nCoV-infected patients were treated, a randomized controlled trial was quickly initiated to assess the efficacy and safety of the combination to treat this emerging coronavirus infection (Huang, C. Elements of the viral replication process have also been identified as potential therapeutic targets, including viral helicase, features of which are highly conserved among different coronaviruses (Adedeji, A. Other potential antiviral drug targets include virus assembly and exocytosis, which enables the release of virus from host cells. Despite a good understanding of viral targets and the identification of potential antiviral agents in vitro and in animal models, however, these findings have not translated into efficacy in humans (Zumla, A. Nine patients were given the combination therapy, while 13 patients were treated with corticosteroids alone.

Platelet Dysfunction In some disorders, the platelets may be normal in number, yet hemostatic plugs do not form normally and the bleeding time will be long. Platelet dysfunction may stem from an intrinsic platelet defect or from an extrinsic factor that alters the function of otherwise normal platelets. Hereditary disorders of platelet function the most common hereditary intrinsic platelet disorders are a group of mild bleeding disorders that may be considered disorders of amplification of platelet activation. Thrombasthenia is a rare hereditary platelet defect that affects platelet surface membrane glycoproteins. Thrombasthenia patients may have severe mucosal bleeding (eg, nosebleeds that stop only after nasal packing and transfusions of platelet concentrates). Bernard-Soulier syndrome is another rare autosomal recessive disorder that affects surface membrane glycoproteins. Serious bleeding in a patient with an intrinsic platelet disorder may require platelet transfusion. Acquired platelet dysfunction Acquired abnormalities of platelet function are very common because use of aspirin, which predictably affects platelet function, is ubiquitous. Aspirin, which modestly prolongs the bleeding time in many healthy persons, may markedly increase the bleeding time in patients with an underlying platelet dysfunction or who have a severe coagulation disturbance (eg, patients who have been given therapeutic heparin or those with severe hemophilia). Platelets may become dysfunctional, prolonging the bleeding time, as blood circulates through a pump oxygenator during cardiopulmonary bypass surgery. Thus, regardless of platelet numbers, patients who bleed excessively after cardiac surgery and who have a long bleeding time should be given platelet concentrates. During bypass surgery, giving aprotinin (a protease inhibitor that neutralizes plasmin activity) reportedly prevents prolongation of the bleeding time and reduces the need for blood replacement. The bleeding time may shorten transiently after vigorous dialysis, administration of cryoprecipitate, or desmopressin infusion. Coagulation disorders Decreased or defective synthesis of one or more of the coagulation factors can cause bleeding. In contrast, several coagulation factors are deficient in most acquired disorders. Hemophilia may result from gene mutations: point mutations involving a single nucleotide, deletions of all or parts of the gene, and mutations affecting gene regulation. About 50% of cases of severe hemophilia A result from a major inversion of a section of the tip of the long arm of the X chromosome. Each son of a carrier has a 50% chance of being a hemophiliac, and each daughter has a 50% chance of being a carrier. Minor trauma can result in extensive tissue hemorrhages and hemarthroses, which, if improperly managed, can result in crippling musculoskeletal deformities. Bleeding into the base of the tongue, causing airway compression, 389 Hematology may be life threatening and requires prompt, vigorous replacement therapy. Even a trivial blow to the head requires replacement therapy to prevent intracranial bleeding. They rarely have spontaneous hemorrhages; however, they will bleed severely (even fatally) after surgery if not managed correctly.

Reduced levels of iron in the liver trigger increases in the synthesis of the iron carrier transferrin (referred to as apotransferrin when not bound to iron), further decreasing levels of iron-bound transferrin, the ligand of the transferrin receptor. Consequently, the uptake of iron from transferrin receptors by all cells and organs.

Cells suspended in an eclectically conductive diluent such as saline are pulled through an aperture (orifice) in a glass tube. In the counting chamber, or transducer assembly, low-frequency electrical current is applied between an external electrode (suspended in the cell dilution) and an internal electrode (housed inside the aperture tube). Electrical resistance between the two electrodes, or impedance in the current, occurs as the cells pass through the sensing aperture, causing voltage pulses that are measurable. Oscilloscope screens on some instruments display the pulses that are generated by the cells as they interrupt the current. The size of the voltage pulse is directly proportional to the size (volume) of the cell, thus allowing discrimination and counting of specific-sized cells through the use of threshold circuits. Pulses are collected and sorted (channelized) according to their amplitude by pulse height analyzers. The data are plotted on a frequency distribution graph, or size distribution histogram, with relative number on the y-axis and size (channel number 455 Hematology equivalent to specific size) on the x-axis. Size thresholds separate the cell populations on the histogram, with the count being the cells enumerated between the lower and upper set thresholds for each population. Size distribution histograms may be used for the evaluation of one cell population or subgroups within a population. Optical scatter Optical scatter may be used as the primary methodology or in combination with other methods. In optical scatter systems (flow cytometers), a hydro-dynamically focused sample stream is directed through a quartz flow cell past a focused light source. The light source is generally a tungsten-halogen lamp or a helium-neon laser (Light Amplification by Stimulated Emission of Radiation). Laser light, termed monochromatic light since it is 456 Hematology emitted as a single wavelength, differs from bright field light in its intensity, its coherence. These characteristics allow for the detection interference in the laser beam and enable enumeration and differentiation of cell types. As the cells pass through the sensing zone and interrupt the beam, light is scattered in all directions. Light scatter results form the interaction between the processes of absorption, (diffraction bending around corners or surface of cell), refraction (bending because of a change in speed), and reflection (backward rays caused by obstruction). Lenses fitted with blocker bars to prevent nonscattered light from entering the detector are used to collect the scattered light. A series of filters and mirrors separate the varying wavelengths and present them to the photo detectors. Photodiodes convert light photons to electronic signals proportional in magnitude to the amount of light collected. Analog-to digital converters change the electronic pulses to digital signals for computer analysis.
