Sixteen patients, suffering from myeloproliferative diseases (9 polycythaemia vera, 7 primary thrombocythaemia) and 20 control subjects were treated for 14 days with 1 g of thiamphenicol per day. The effect of 40 treatment cycles was studied. The regimen resulted in lowering the haemoglobin values by 4.8070 in controls (p >_ 0.001) and patients (p >_ 0.01); the reticulocyte count dropped 43 °7…
Granulocyte colony-stimulating factor (G-CSF; filgrastim) and its pegylated form (pegfilgrastim) are widely used to treat neutropenia associated with myelosuppressive chemotherapy and bone marrow transplantation, AIDS-associated or drug-induced neutropenia, and neutropenic diseases. G-CSF facilitates restoration of neutrophil counts, decreases incidence of infection/febrile neutropenia and redu…

STRONG EVIDENCE HAS been provided to indicate that chloramphenicol-(CAP) induced reversible bone marrow suppression results from inhibition of mitochondrial protein synthesis and consequent mitochondrial injury. ı Suppression of ferrochelatase activity, a mitochondrial-membraneassociated enzyme, with a block in the last step of heme synthesis has been suggested as a basis for the apparent vuln…
Thiamphenicol is a semisynthetic structural analogue of chloramphenicol (CAP)(Sutter and Finegold, 1976). Chemically, it is D-d-threo-2-dichloro acetamido-l-(4-methylsulfonyl)-phenyl-l, 3-propanediol and has been derived by replacing the p-nitrophenol group of chloramphenicol by methylsulfonyl moietv
Chloramphenicol is an old antibiotic that also inhibits mammalian mitochondrial protein synthesis. Our studies demonstrated that chloramphenicol is highly cytotoxic to myeloma cells, acting in a dose- and time-dependent manner. Chloramphenicol sharply suppressed ATP levels in myeloma cells at concentrations ≥ 25 μg/mL. Colorimetric and clonogenic assays indicate that chloramphenicol inhibit…
There is now 16 years’ worth of established results of various trials demonstrating the bortezomib efficiency in the treatment of multiple myeloma. Over this time, the introduction of bortezomib has been a major break through in the treatment of multiple myeloma. Bortezomib can be administered in the outpatient setting with manageable toxicities.
We conducted a systematic review to determine the appropriate use of bortezomib alone or in combination with other agents in patients with multiple myeloma (mm). We searched medline, embase, the Cochrane Library, conference proceedings, and the reference lists of included studies. We analyzed randomized controlled trials and systematic reviews if they involved adult mm patients treated wit…
Multiple myeloma is a malignancy of plasma cells accounting for approximately 1% of cancers and 12% of haematological malignancies. The first-in-class proteasome inhibitor, bortezomib, is commonly used to treat newly diagnosed as well as relapsed/refractory myeloma, either as single agent or combined with other therapies
