We report a case of a severe Fusarium solani keratitis in a 82-year-old patient with a history of surgical trauma. Antimycotic therapy and keratoplasty led to markedly improved vision. Identification of the fungus was complicated by the fact that the isolate did not produce the typical macroconidia. The second case was a fatal disseminated Fusarium verticillioides infection in a 69-year-old patient during neutropenia after chemotherapy of acute myelogenous leukemia. The patient developed pneumonia, fever, skin lesions, myalgia, and fungaemia. The clinical signs, diagnosis and therapy of localized and disseminated Fusarium infections are outlined and discussed in view of the literature.

L-selectin is a glycoprotein which is one of three members in a family of cell adhesion molecules called selectins. L-selectin is present in distinct forms on both neutrophil granulocytes and lymphocytes, and it appears to play an important role in the early stages of leukocyte-endothelial cell interaction. Activation of leukocytes leads to shedding of the extracellular part of L-selectin which thus forms a soluble adhesion molecule, sL-selectin, which retains functional capacity and can be detected in serum. In the present study we have developed a specific, sensitive sandwich ELISA to measure the serum level of sL-selectin in patients with hematological and infectious disorders. Three patients with acute myeloid leukemia in remission and 1 patient with chronic myeloid leukemia in chronic phase were followed during bone marrow transplantation and the level of sL-selectin was found to correlate closely to the leukocyte counts with no detectable sL-selectin during periods of severe leukopenia. In 11 patients with chronic phase chronic myeloid leukemia and 13 patients with chronic lymphocytic leukemia the sL-selectin level was also found to correlate closely to the leukocyte count (R = 0.98; p = 0.001 and R = 0.83; p = 0.004 respectively). One CML patient with a leukocytosis of 385 x 10(9)/l was found to have an sL-selectin concentration 625 times above normal. Ten patients with acute pneumonia were evaluated at diagnosis and at the time of follow-up 4-8 weeks later. In all patients the initial sL-selectin level was higher than at follow-up. However, no close correlation between sL-selectin and leukocyte count or CRP (C-reactive protein) at the time of diagnosis was found. In summary, we have found that the sL-selectin level in human serum closely correlates to the leukocyte count in both CML and CLL and during bone marrow transplantation.

The activation of autologous cytotoxic cells by interleukin-2 (IL-2) may be a promising tool for elimination of minimal residual blast populations in patients with acute myelocytic leukemia (AML) to prolong disease-free survival. Here, we report the results of a phase II study using IL-2 for consolidation therapy in patients with second remission of de novo AML. All patients in 1st relapse of AML received a uniform induction therapy consisting of intermediate high-dose AraC (iHDAraC) 2 x 600 mg/m2 d1-4 and VP-16 100 mg/m2 d1-7. Patients achieving 2nd remission were treated with 4 cycles recombinant IL-2 (rIL-2) 9 x 10(6) IU/m2 administered on d1-5 and 8-12/cycle as 1h infusion every six weeks. In 37/66 (56%) evaluable patients, complete remission (CR) was achieved. So far, 21/37 patients (4 after additional autologous bone marrow transplantation (ABMT) received rIL-2 consolidation. Three patients are too early for evaluation, 4 received allogeneic BMT, 6 relapsed before IL-2 was scheduled and 4 refused treatment with rIL-2. The median disease-free survival (DFS) was 11 (4-49+) months. Up to now, in 5/21 (24%) patients the duration of 2nd remission exceeded that of 1st remission 7/21 (33%) are in ongoing 2nd remission (7+ to 49+ months). The side effects of rIL-2 were generally moderate and manageable. Only in two patients, previously treated with ABMT, severe side effects occurred; septicaemia and pneumonia in one patient and desquamative erythrodermia in the second one. In accordance with other studies rebound lymphocytosis with a marked increase of CD56(+)-cells and release of secondary cytokines such as TNF-alpha, IFN-gamma and IL-6 was observed. The schedule is feasible and the data suggest a possible benefit for DFS, which, however has to be confirmed by randomized trials.

A 16-year-old girl with refractory AML received unmanipulated BMT from an unrelated donor. Leukemia relapse occurred 82 days later. The patient was then treated with IL-2 1.8 x 10(6) U/m2 for 5 days per week and 2.5 MU/m2 IFN-alpha three times per week. Toxicities included fever, skin rash, somnolence and a generalized seizure. Treatment was stopped after 2 weeks. Acute GVHD developed at the end of therapy and the patient's leukemia went into remission. She died of fungal pneumonia 30 days later. We conclude that a combination of cytokines may be useful in treating relapsed leukemia after BMT.

In a study of 94 patients with myelodysplastic syndrome (MDS) associated vasculitis was observed in 5, which preceded hematologic diagnosis in 4. Leukocytoclastic vasculitis was observed in 5 cases being associated to lobular panniculitis in one. Three patients had refractory anemia, one sideroblastic anemia (SA) and another refractory anemia with excess blasts (RAEB). In the latter case lymphomatoid papulosis was also observed which, to date, has not been previously described in association with MDS. Another case presented seronegative polyarthritis and renal disease coinciding with vasculitis. Polyarteritis nodosa was diagnosed in a third patient in agreement with the criteria of the American College of Rheumatology, the association of which with MDS is exceptional. In the same case medullary cytogenetic study showed 46, XY,t (12;20), an abnormally which has not been described to date in cases of MDS. All the cases were treated with glucocorticoids in addition to cyclophosphamide in the patient with polyarteritis nodosa, with an improvement in the vasculitis being observed in all the patients. Two patients died, one (SA) due to pneumonia and the other (RAEB) due to subdural hematoma following transformation to acute myeloblastic leukemia. With 5% of the MDS studied presenting vasculitis, this syndrome should be included in the differential diagnosis of vasculitis observed in patients with cytopenia.

Using the envelope method, we allocated 125 patients with infections accompanied by hematopoietic disorders into two groups treated with imipenem/cilastatin sodium (IPM/CS) at a daily dose of 1 g/1 g b.i.d. (group BID) or 0.5 g/0.5 g q.i.d. (group QID), and obtained the following results. 1. In group BID, ANLL was observed in 25 patients; ALL in 6; and NHL in 12. In group QID, ANLL was observed in 27 patients; ALL in 7; and NHL in 13. 2. In group BID, efficacy rates were 54.5% (6/11) in sepsis, 63.0% (17/27) in fever of undetermined origin and 50.0% (4/8) in pneumonia, thus the overall efficacy was 61.8% (34/55). In group QID, efficacy rates were 66.7% (4/6) in sepsis, 76.0% (19/25) in fever of undetermined origin and 35.7% (5/14) in pneumonia, thus the over all was 61.1% (33/54). No significant difference in response rates were observed between the two groups. 3. Bacteriologically, 22 bacterial strains were isolated in group BID and 21 21 strains, in group QID. The eradication rates after treatment with IPM/CS was 100% in group BID and 66.7% in group QID. 4. Side effects were observed in 8 patients in group BID and 3 in group QID. Laboratory examination revealed abnormal values in 9 patients in group BID and 6 in group QID. However, all of the side effects disappeared after the suspension or discontinuation of IPM/CS. The efficacies of IPM/CS therapy for severe infections in patients with hematopoietic disease were similar between 1 g/1 g b.i.d. and 0.5 g/0.5 g q.i.d. groups.

Seventy-three BMT procedures (42 allogeneic-BMT, 30 autologous-BMT, 1 syngeneic transplant) were undertaken at the Shariati Hospital in Tehran between March 1991 and November 1993. Allogeneic-BMT was performed for thalassaemia major (n = 23), AML in complete remission (n = 3), severe aplastic anaemia (n = 7), CML (n = 7), dyskeratosis congenita (n = 2) and Fanconi anaemia (n = 1). Conditioning regimens comprised busulphan (BU) plus cyclophosphamide (CY) or CY only. Thirty-two (78%) of the 43 patients remain alive 1-34 months after BMT. Twelve patients died: the causes of death were haemorrhagic cystitis (n = 1), CMV pneumonitis (n = 1), GVHD (n = 3), infection (n = 3), rejection (n = 1), VOD (n = 2) and hepatitis (n = 1). Autologous-BMT was performed for patients with AML in CR (n = 16), ALL in CR (n = 9), lymphoma in relapse (n = 3), Ewing sarcoma (n = 1) and multiple myeloma (n = 1). The median age was 18 years. Conditioning regimens were Ara C plus CY, etoposide plus CY and high-dose melphalan. Sixteen (54%) of the 30 patients survive, 14 in continuous complete remission. The causes of death were relapse (AML (n = 7), ALL (n = 4), lymphoma (n = 1)), VOD (n = 1) and infection (n = 1).

The administration of granulocyte-monocyte colony-stimulating factor (GM-CSF) was associated with complete clinical and haematological response in an adult patient with minimally differentiated acute myeloid leukaemia who presented with pneumonia and moderate neutropenia, but no blast cells in the peripheral blood. The response lasted 9 months. At relapse, a second GM-CSF course resulted in a very good partial remission lasting 5 months, although differences in the kinetics of haemoglobin, neutrophil and platelet recovery were noted. Subsequent recurrences were managed with chemotherapy, a complete remission being obtained twice more and lastly consolidated with myeloablative chemo-radiotherapy supported by a peripheral blood stem cell autograft. This report suggests that GM-CSF should be further investigated as a therapeutic agent in selected cases of AML.

The clinical course of 16 patients with polycythemia vera (PV), treated in the period 1982 to 1993, was shown. Splenomegaly occurred in three fourths of these patients (75%), and hypertension was a major symptom. Thrombosis such as myocardial infarction and cerebral infarction was noted. Eight patients was treated with myelosuppressive agents and the 8 other patients were treated with phlebotomy. A 70-year-old male who was treated with mitobronitol (DBM) developed acute myeloblastic leukemia (AML) 11 years later. He was treated with multi-combination chemotherapy (BHAC-DMP), and entered complete remission, followed by early relapse. He became refractory to chemotherapy and died of acute pneumonia 6 months later. Median survival of 16 cases of PV was more than 10 years, and long-term treatment and care are necessary.

Arbekacin (ABK) was administered to 17 patients with MRSA infections that complicated underlying hematopoietic disorders, and the efficacy and safety were evaluated. The underlying diseases included acute myelocytic leukemia (8 cases), acute lymphocytic leukemia (1) myelodysplastic syndrome (3), chronic myelocytic leukemia (1), non-Hodgkin's lymphoma (2), Hodgkin's disease (1) and adult T cell leukemia (1). The infections consisted of septicemia (5 cases), pneumonia (4), upper respiratory tract infections (6) and urinary tract infections (2). ABK was administered by i.v. drip infusion in daily doses of 150-200 mg, given in two divided dosages. The therapeutic efficacies were: excellent in 2 (2 septicemias), good in 7 (1 septicemia, 4 upper respiratory infections, 2 urinary tract infections), fair in 2 (septicemia and pneumonia) and poor in 6 (1 septicemia, 3 pneumonias, 2 upper respiratory infections). As a side effect, reversible renal dysfunction was detected in four cases. Causative bacteria were isolated from six cases. They were all coagulase type II and MIC's of ABK were from 0.25 microgram/ml to 4.0 micrograms/ml. Arbekacin therapy was found to be effective even in patients with hematopoietic disorders accompanied by MRSA infections.
