Overview: cladribine when available ; pharmacology and use : cladribine is a synthetic antineoplastic agent indicated for the treatment of active hairy cell leukemia as defined by clinically significant anemia, neutropenia, thrombocytopenia or disease-related symptoms.
Although there is no evidence of teratogenicity in humans due to cladribine, other drugs which inhibit DNA synthesis e.g., methotrexate and aminopterin ; have been reported to be teratogenic in humans. Cladribine has been shown to be embryotoxic in mice when given at doses equivalent to the recommended dose. There are no adequate and well controlled studies in pregnant women. If cladribine is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing age should be advised to avoid becoming pregnant.

Introduction It is proposed that mantle-cell lymphoma MCL ; , previously described as centrocytic lymphoma in the Kiel Classification, be defined as a new entity by the Revised European-American Classification of Lymphoid Neoplasms R.E.A.L. ; [1]. MCL patients are resistant to current therapeutic strategies and have the shortest median survival of all those with lymphoma entities with a median survival of three to four years, irrespective of the initial treatment [2]. New agents are therefore needed to improve on the prospects of current treatment approaches. Cladribine 2-chlorodeoxyadenosine, 2-CdA ; is a newer purine analogue resistant to deamination by adenosine deaminase [3, 4], which has shown high activity - response rates from 42% to 88% - in the treatment of low-grade lymphomas [5-8]. In most studies cladribine was administered as continuous infusion for seven days. The objective of the present study was to evaluate the efficacy and toxicity of cladribine as an intermittent twohour infusion over five days in patients with MCL as first-line therapy or therapy of first relapse.
LEO July 23-Aug. 22 ; : Can you feel the moon tugging at the fluids in your body? Usually, you can't. Are you aware of how large-scale cultural influences affect your day-to-day rhythms? Again, that's typically beyond your capacity to sense in any immediate way. But this week, you just might be able to do both of those things. You're more attuned than usual to the subtle currents that are unfolding within you. You're also more alert to the impact that big cosmic energies and long-term historical trends are making on your unconscious mind. I advise you to take maximum advantage of this extra sensitivity. You could discover important clues about how to position yourself to thrive in the face of upcoming social transformations. P.S. Listen reverently to the secrets your body tells you.
The classes are roughly described as follows. Class A-type This class includes drugs such as cladribine and irinotecan. Cladribine is an old drug that is going to find a new application against the multiple sclerosis. Irinotecan belongs to the group of medicines called anti-neoplastic. It has been used to treat cancer of the colon or rectum and, more recently, decrease levels of folic acid ; . Class B-type This class includes a particular set of drugs produced by means of biotechnologies, such as monoclonal antibodies. These drugs have an application to certain specific diseases. Among them the more representative are trastuzumab a monoclonal antibody that belongs to laboratory-made drugs designed to attack specific cancer cells that produce the HER2 protein ; , abciximab anti-coagulant ; or rituximab used to treat nonHodgkin's lymphoma ; . Class C-type This class refers to a wide set of drugs such as: rosiglitazone for therapy of Type 2 diabetes mellitus also in combination therapy with insulin ; , for the large number of human cases considered, and sibutramine anti-obesity ; . In this class we also put sildenafil citrate Viagra ; , ropinirole used to treat symptoms of Parkinson's disease ; and rivastigmina tartrate an Alzheimer's disease treatment ; . tested in combination with 5-fluorouracile and leucovorin the active form of the B complex vitamin, folate, used as an antidote to drugs that.

The finding that both tezacitabine and cladribine are significantly toxic toward HL-60 leukemia cells in vitro confirms results reported previously Skierski et al., 1999; Grieb et al., 2000 ; . The novel observation of the present study is that the increase in the cytotoxic effects of FMdC over time is much more pronounced than that of 2CdA. Since we were unable to find any data concerning intracellular pharmacokinetics of FMdC, we may only speculate on the reasons of this difference. Cladribine and tezacitabine display somewhat different mechanisms of cell killing. At clinically achievable doses inhibition of ribonucleotide reductase is believed to be the principal mediator of tezacitabine cytotoxicity Takahashi et al., 1998 ; , whereas it seems to play a minor role in cladribine toxicity Griffig et al., 1989 ; . Cladribine cytotoxicity is highly selective toward leukemic cells, whereas tezacitabine is active also toward a range of solid tumors. On the other hand, both nucleoside analogs share the requirement of intracellular activation by cytidine kinase-dependent phosphorylation to exert their cytotoxic effects, both are resistant to deamination by respective deaminases and accumulate as phosphates in the target cells Liliemark, 1997; Takahashi et al., 1998 ; . There are at least two possible explanations of the increase of FMdC but not 2CdA ; cytotoxicity over time. One may consider the possibility that in HL-60 cells the system of transport and intracellular activation of 2CdA is for some reasons much more efficient, relative to the intracellular accumulation of the active form of the drug required for cytotoxicity, than that for FMdC. If FMdC phosphates accumulate in leukemic cells at a significantly lower relative rate than 2CdA phosphates, longer exposure time will be required to achieve maximal cytotoxicity of the former drug. Also, our experiments do not exclude the possibility that both FMdC and 2CdA phosphates quickly accumulate in the target cells but for some other reasons the cellular cytotoxic re.
Cladribine mechanism of action
Lipid-based drug delivery systems DDS ; can play a direct role in improving efficacy and drug safety, whereby new and improved therapies are possible. This has stimulated the creative design and study of lipid-based carriers for delivery through different portals of the body. Colloidal-sized lipid particles in aqueous media, and their pre-concentrated dosage forms, have found important applications in a range of drug products, featuring all routes of administration. Lipid self-assembly structures even find use as matrices for injectable depot products. When dissolved in aqueous media, lipids selfassemble to form a wide range of mesophase structures Figure 1 ; . The complex architectures can be advantageously utilised to facilitate solubilisation, stabilisation, and delivery of different drug substances. Well-known self-assembly structures creatively utilised in pharmaceutical products include Sandimmun Neoral microemulsion, Novartis ; , Diprivan emulsion, AstraZeneca ; , and Doxil `Stealth' liposome, ALZA ; . More recently, lipid-based, self-assembled liquid crystalline LC ; structures of cubic and hexagonal phases, and their corresponding nanoparticles Cubosome and Hexosome ; , have emerged as potential carriers for several applications. The broad solubilisation spectrum together with high drug payloads, as well as the ability to protect sensitive substances like peptides and proteins, and facilitate absorption, make these LC systems interesting alternatives to the more commonly used micelle, microemulsion, emulsion and liposome systems. Similar to microemulsions, emulsion and liposomes, they can be designed to self-disperse into colloidal particles. This property is essential in many applications where water-free liquid or powder preconcentrates are the desired dosage forms. Lipids are ubiquitously distributed and play fundamental roles in the architecture and functionality of all living cells. Human health is dependent on the regular ingestion of various lipids because of their role in maintaining normal cellular and clorazepate.
Hyperuricemia during periods of active cell lysis, which is caused by chemotherapy of highly proliferative tumours of massive burden e.g., some leukemias and lymphomas ; , can be minimized with allopurinol and hydration. In hospitalized patients the urine may be alkalinized, by addition of sodium bicarbonate to the IV fluids, if tumour lysis is expected. Severe bone marrow suppression, including neutropenia, anemia and thrombocytopenia, has been commonly observed in patients treated with cladribine, especially at high doses. 44% of patients need red cell transfusions, and 14% platelet transfusions in the first month of therapy. Cumulative myelotoxicity and prolonged thrombocytopenia can occur after multiple cycles. Pancytopenia has been reported and occurs in 20% of patients with mycosis fungoides. Cladribine can be immunosuppressive, causing a reduction in the number of CD4 helper ; and CD8 suppressor ; T lymphocytes, which can last for years. However, no increase in life-threatening opportunistic infections or secondary malignancies has been reported. Febrile episodes are common 46% ; in hairy cell leukemia patients, but are not a direct side effect of the drug. The fever appears to correspond to the time of maximal lysis of malignant cells and may occur as the result of the release of endogenous pyrogens. Fever does not usually occur when cladribine is used to treat other malignancies. Infections are common in patients receiving cladribine. Typical sites of infection include the lungs and sites of venous access. Septicemia has also been reported. Hairy cell leukemia patients with pancytopenia and especially lymphopenia prior to cladribine appear to be at increased risk of developing a serious infection. High doses 0.26 mg kg day x 10-14 days ; in conjunction with cyclophosphamide and total body radiation as preparation for bone marrow transplantation, have been associated with severe, irreversible neurologic toxicity paraparesis, quadriparesis, axonal poyneuropathy, demyelination ; and or acute renal impairment some patients required dialysis ; in up to 45% of patients. Axonal neuropathy has been reported with high doses of cladribine alone. Although neuropathy was seen in the phase I studies at the highest doses, at the recommended dose for hairy cell leukemia 0.09 mg kg day x 7 days ; , no similar neurotoxicity or nephrotoxicity has been reported.

The two major interactions which determine the particle counts in our experiments are i ; non-specific adsorption which in complex systems may be inhibited competitively and ii ; specific serological binding. Each interaction alone may bring about the trapping of roughly equal amounts of particles; similar results have been obtained with viruses from other groups P. Korpraditskul & D. E. Lesemann, unpublished data ; . The least complicated system studied here was the trapping of purified virus particles on buffer-treated grids. This is an adsorption process which results in high particle counts. The interaction involved in this non-specific adsorption apparently differs between viruses since different numbers of particles were adsorbed from equal concentrations of BMV, OYMV, ScrMV and TYMV. Adsorbed particles of one virus component could be replaced by the other component. When the virus and crude plant sap were applied to buffer-treated grids, there was apparently a competition between virus particles and constituents of the crude plant sap for the adsorption sites. Since far less virus particles were adsorbed when purified virus was diluted in crude plant sap instead of buffer, it would appear that the majority of the non-specific adsorption sites were blocked by plant sap constituents Blocking of non-specific adsorption sites apparently also took place when the grids were pre-treated with NS. The amount of inhibition also depended on the virus. Viruses which gave higher counts on buffer-treated grids e.g. BMV ; also gave higher counts on NS-coated grids. It is reasonable to assume that on grids coated with homologous AS a large number of non-specific adsorption sites would be blocked by serum constituents. However, the presence of antibodies gave specific serological binding. Thus, particle counts on AS-coated grids were of the same order of magnitude as those on buffer-treated grids. In contrast to the non-specific adsorption, the serological binding seemed to be more or less irreversible. In addition, serological binding was not inhibited by constituents of crude plant sap. For this reason the Derrick method should allow more accurate comparisons of the concentrations of virus particles in purified and crude sap preparations than would the conventional adsorption methods. By simultaneous application of the Derrick method and the conventional adsorption method some information might be gained on the purity of virus preparations. The adsorption of far fewer particles on to buffer-treated grids than on to AS-coated grids may indicate that the preparation contained large amounts of contaminating proteins or degradation products which inhibited the adsorption, but not the serological binding. The virus concentration also influenced the particle counts. The linear relationship between log virus concentration and log number of particles trapped found for ScrMV and OYMV below ~o b'g ml is similar to observations on the binding of other viruses to AS-coated grids Derrick, I973; Paliwal, r977; Beier & Shepherd, I978 ; .

Organizing pneumonia also occurs in rheumatoid arthritis and Sjgren's syndrome. Pathological features of organizing pneumonia which may be present in Wegener's granulomatosis usually consist of small foci of organizing pneumonia at the periphery of otherwise typical granulomatous lesions. It is well established that both lung transplantation and bone-marrow grafting may be complicated by constrictive mural bronchiolitis obliterans with airflow obstruction. Less commonly, organizing pneumonia occurs in transplanted lungs or after allogeneic bone marrow grafts. Clinical description Clinical characteristics [2, 3, 5, 15-19] Men and women are affected equally and are usually aged between 50 and 60 years. No predisposing factors have been identified. The onset of symptoms is usually subacute with fever, nonproductive cough, malaise, anorexia and weight loss. Haemoptysis, bronchorrhea, chest pain, arthralgia and night sweats are uncommon. Dyspnea, usually mild, is occasionally severe in some acute and lifethreatening cases. In most cases, symptoms develop over a few weeks sometimes after a viral-like illness ; , and the diagnosis of COP is usually made after 6 to 10 weeks. At physical examination sparse crackles may be heard over affected areas. Imaging [2-5, 16, 18, 20-23] The radiographic and computed tomography CT ; scan findings are characteristic in typical cases. They suggest the diagnosis when multiple patchy alveolar opacities with a peripheral and bilateral distribution are present. Their size ranges from a few centimetres to a whole lobe, their density varies from ground glass opacification to airspace consolidation with an air bronchogram. Other less common imaging patterns consist of either diffuse bilateral infiltration associating interstitial opacities and small superimposed alveolar opacities, or solitary focal lesions often excised when lung cancer is suspected ; which may correspond to unresolved pneumonia in some cases. Lung function tests [5, 21, 24, 25] The most common finding on lung function testing in patients with COP is a mild or moderate restrictive ventilatory defect. Airflow obstruction may be present in smokers. The transfer factor for carbon monoxide is reduced. Mild hypoxemia at rest and or on exercise is common. Hypoxemia is occasionally severe and cogentin.
