[Collagenofibrotic glomerulopathy--rare glomerulonephritis].

Glomerulopathies with fibrillary deposits form a heterogeneous group of renal diseases that can be identified only by means of electron microscopy. A case of a rare type of such a nephropathy, the collagenofibrotic glomerulopathy with focus on differential diagnostics is presented and current knowledge relating to this renal disease is reviewed.

Philadelphia-positive chronic myelogenous leukemia with a 5q-- abnormality in a patient following interferon-alpha therapy.

In this report, we describe a rare 5q--/CML association in a patient with Ph-positive chronic myelogenous leukemia (CML) who achieved complete cytogenetic response on interferon-alpha (IFN-alpha) treatment, but who developed a new clone in the blastic crisis. The patient was treated with interferon-alpha beginning in 1996 and a serial chromosome and molecular study was performed over the clinical course of the disease. The patient remained in complete hematologic and cytogenetic remission until November 1998, when a reverse transcriptase PCR study performed on the bone marrow and peripheral blood cells was negative for chimeric BCR/ABL mRNA.

[Hypercirculatory heart failure in a patient with plasmacytic leukemia].

High cardiac output failure/state (HCOF) is regular feature of some illnesses e.g. thiamine deficiency, hyperthyroidism, severe anemia, Paget's disease or arteriovenous fistulae.

[Significance of laboratory examinations in the diagnosis of iron-deficiency anemia in older persons].

In order to assess the effectiveness of selected laboratory examinations in the differential diagnosis of anaemias in elderly patients the authors examined 170 patients aged 65-93 years. Depending on the cause of anaemia, they divided the group into five sub-groups. Analysis revealed that for the diagnosis of iron-deficiency anaemia the mean corpuscular volume and red cell haemoglobin level have a relatively low sensitivity (63 and 65.

Chronic lymphoproliferative disease of large granular lymphocytes.

An 80-year-old patient has been followed for hepato- and splenomegaly, hemolytic anemia, neutropenia with lymphocytosis with large granular lymphocyte predominance in his peripheral blood, with infiltration of bone marrow, liver and probably also spleen. Determination of surface markers of proliferating lymphocytes in peripheral blood showed a mixed phenotype of T suppressor/cytotoxic and natural killer cells (SIg-, E+, T3+, T8+, EAC+, Leu7-, N901+, NK9+, VIB C5 and VIB E3-, Ia-). An in vitro cytotoxic test showed the functional inactivity of the cells tested also after human leukocyte interferon stimulation.
