A case of Waldenström's macroglobulinaemia is presented where marrow examination was normal and production of the abnormal protein was centered on the lungs. Symptomatic and biochemical improvement was achieved with chlorambucil and prednisone. Lung manifestations in the disease are briefly reviewed.

The evolution of Waldenström's macroglobulinemia (WM) into chronic or acute myeloid leukemia (AML) is a rare event. Most of these cases have occurred after treatment with alkylating agents. We herein report a case of WM terminating in an acute myelomonocytic leukemia after treatment with prednimustine and chlorambucil and present a review of the literature.

Prolonged clotting times were observed in a patient with spontaneous hemorrhage. Analysis showed severe factor X deficiency due to clearance by a noninhibitory antibody. Lymphadenopathy identified on imaging led to diagnosis of marginal B-cell lymphoma. Treatment of lymphoma with rituximab and chlorambucil resulted in complete disappearance of the bleeding disorder.

There is now controlled evidence that a 6-month course with methylprednisolone and chlorambucil may favour remission of the nephrotic syndrome and may significantly improve the 10-year kidney survival in patients with idiopathic membranous nephropathy. We analyzed the outcome of 15 nephrotic patients (proteinuria 7.06 +/- 1.07 g/d), stage II-III membranous nephropathy, aged 37.93 +/- 2.32, 8 ma...

Previous NMR studies demonstrated that lonidamine (LND) selectively diminishes the intracellular pH (pHi) of DB-1 melanoma and mouse xenografts of a variety of other prevalent human cancers while decreasing their bioenergetic status (tumor βNTP/Pi ratio) and enhancing the activities of melphalan and doxorubicin in these cancer models. Since melphalan and doxorubicin are highly toxic agents, we ...

O-Benzylguanine (BG) inactivates O-alkylguanineDNA alkyltransferase (AGT), resulting in an increase in the sensitivity of cells to the toxic effects of Oalkylating agents. BG significantly enhances the cytotoxicity and decreases the mutagenicity of nitrogen mustards [i.e., phosphoramide mustard (PM), melphalan, and chlorambucil], a group of alkylating agents not known to produce O-adducts in DN...

O6-Benzylguanine (BG) inactivates O6-alkylguanine-DNA alkyltransferase (AGT), resulting in an increase in the sensitivity of cells to the toxic effects of O6-alkylating agents. BG significantly enhances the cytotoxicity and decreases the mutagenicity of nitrogen mustards [i.e., phosphoramide mustard (PM), melphalan, and chlorambucil], a group of alkylating agents not known to produce O6-adducts...

Background: Apoptosis-related gene expression such as BCL2, and p53 has been suggested in predicting the patient response to chemoor radiotherapy, as well as patient’s survival. Methods: The aim of this study was to determine changes in BCL2 and p53 apoptosis related gene expressions in chronic lymphocytic leukemia (CLL) patients in response to different chemotherapy regimens and number of trea...

Authors' disclosures of potential conflicts of interest are found at the end of this article. T he management of chronic lymphocytic leukemia (CLL), a malignant disorder of the lymphoid lineage (primarily B cells), has changed considerably in recent years. The development of agents targeting CD20, a trans-membrane calcium channel protein expressed on B cells, was a significant milestone in the ...

A case of primary macroglobulinaemia of Waldenström is described in which prolonged treatment with the alkylating agents of cyclophosphamide and chlorambucil led to a sustained reduction in the concentration of circulating macroglobulin together with a concurrent improvement in the patient's symptoms.
