Two hundred and sixty-two patients (actual number 162) of hematological malignancies were admitted to our department from November 1977 to December 1986. Fourty-three of them (16.4%) were demonstrated to be accompanied with sepsis by blood culture. In acute non-lymphocytic leukemias (AML, APL, AMoL) the rate of sepsis was 33.8% (27 patients), while in lymphocytic malignancies (ML, HD, ATL) it was 11.7% (16 patients), particularly being 3.0% in ATL. Among the detected pathogenic microorganisms, gram-negative bacilli were 86.2% in the former and 50.0% in the latter. Especially, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli occupied 58.6% of the total in the former. Laboratory examination, when sepsis occurred, revealed peripheral neutropenia in acute non-lymphocytic leukemias (mean 831/cmm) but not in lymphocytic malignancy (mean 4,420/cmm). And 20 of the 27 cases showed remarkable neutropenia of below 500/cmm in the former. On the other hand in the latter, out of 16 only one with ATL was the case. Hypogammaglobulinemia was one of the characteristic features in lymphocytic malignancies but not in acute non-lymphocytic leukemias. Hypogammaglobulinemia in lymphocytic malignancies might be affected by long-term immunodepressant therapy. Immunologic skin reaction was demonstrated to be decreased in lymphocytic malignancies on admission. From the findings mentioned above, affecting factors to infections may be mainly neutropenia in acute non-lymphocytic leukemias and immunodeficiency in lymphocytic malignancies. And sepsis can occur frequently under neutropenic condition. In ATL both of humoral- and cellular-immunologic disturbance were detected before therapy. But peripheral neutrophil count was maintained to be normal and this could be the reason for the low septic incidence in ATL despite of total immunodepression.

Graft-versus-host disease (GVHD) is a life threatening complication that may occur following allogenic bone marrow transplantation (BMT) in the patients with aplastic anemia, leukemia or genetic immunodeficiency. It has been known that GVHD occurs approximately 70% of recipients of BMT in western countries but no definite incidence has been reported in Korea. In our St. Mary's Hospital, GVHD occurs in about 30% of BMT recipients. Histopathologically the acute phase skin shows diffuse lymphocytic infiltrates in the upper dermis with extensive exocytosis. Scattered throughout the epidermis are many degenerated keratinocytes, which are often associated with one or more satellite lymphocytes (satellite cell necrosis). In the chronic phase, acanthosis, eosinophilic keratinocytes resembling colloid bodies and mononuclear cell infiltrates in the upper dermis are noted. We reviewed 5 cases of acute GVHD and 6 cases of chronic GVHD. All patients received allogenic BMT from Jan. 1, 1992 to July 1, 1993. Ten patients were male and one was female. The mean age was 34 (20-70). The pathologic diagnosis was 3 cases of CML, 2 of ALL, 2 of AML (FAB M2), 2 of aplastic anemia, 1 of CLL and 1 of AML (FAB M5). The interval from BMT to GVHD varied from 14 days to 4 years (median 220 days). The skin and GI tract were involved in all eleven cases. Ten cases were histologically proven by skin biopsies, and two cases by salivary gland and colonic biopsies, respectively. The histological findings of the skin, salivary gland and colonic biopsieds were described. Immunohistochemical stain of the skin was done using CD4, CD8, HLA DR and Leu 7 antibodies.(ABSTRACT TRUNCATED AT 250 WORDS)

Bone marrow transplantation is now being performed in children having a variety of hematologic malignancies and solid tumors. Marrow donors for patients with hematologic malignancies are usually allogeneic, including HLA-identical siblings, one-antigen mismatched family members, unrelated matched donors, or in some situations, two- or three-antigen mismatched family member donors. Umbilical cord blood is being explored as a source of hematopoietic reconstitution for some allogeneic transplants. Recipients with solid tumors most often receive autologous marrow or PBSC grafts. Posttransplant complications continue to include acute and chronic GVHD, infections, prolonged immunodeficiency, and recurrent malignancy. Because children are now surviving longer after transplantation, a variety of delayed effects are becoming apparent. These include, but may not be limited to, neuroendocrine dysfunction, neuropsychological effects, and ocular and pulmonary dysfunction. Secondary malignancies are now also becoming apparent, particularly among patients surviving more than 10 years after transplantation. Despite these known problems, marrow transplantation remains the treatment of choice for patients who relapse from conventional chemotherapy and for patients with CML in chronic phase and AML in first remission. Research continues to develop methods to decrease posttransplant complications and, hence, increase the probability of long-term disease-free survival.

IL-10 plays an important role in the control of immune reactions during systemic infection. Here, IL-10 serum levels were investigated in patients after BMT. The IL-10 levels correlated with the clinical course of the patients and with serum levels of C-reactive protein (CRP) and neopterin (NP). A total of 26 patients with AML (7), ALL (12), CML (2), NHL (3) and multifocal Ewing's sarcoma (2) had received autologous (10) or allogeneic (16) BMT from related (9) or unrelated donors (7). Routine serum samples were obtained prior to BMT and at days 46 and 100 after BMT. However, in patients with severe complications additional samples were drawn at individual points in time. Prior to BMT, IL-10 serum levels were not detectable in 24/24 patients. Post-BMT, 11 patients developed elevated IL-10 levels, of these eight died of complications (DOC), whereas only one of 15 patients with undetectable IL-10 died of complications, indicating that high IL-10 levels were significantly correlated with severe life-threatening complications (chi2, P < 0.01). To determine the pathomechanism and role of the increased IL-10 levels, they were correlated to the respective NP and CRP serum concentrations. CRP and NP concentrations were found significantly elevated in patients with detectable IL-10, indicating a severe acute phase reaction associated with macrophage activation. In conclusion, high IL-10 serum levels in patients after BMT were significantly associated with fatal outcome. Since IL-10 is a strong suppressor of T cell immunity, high IL-10 production in patients with severe complications such as septic shock or GVHD > grade II after BMT might lead to functional immunodeficiency contributing to the poor prognosis of these patients.

X-linked lymphoproliferative syndrome is an inherited immunodeficiency for which the responsible gene is currently unknown. Several megabase-sized deleted regions mapping to Xq25 have been identified in XLP patients, and more recently a 130-kb deletion has been reported (Lamartine et al., 1996; Lanyi et al., 1996). To establish a physical map of this deleted region and to identify the XLP gene, two cosmid contigs were established (Lamartine et al., 1996). However, the physical map of this region is still uncompleted and controversial and three points remain unsolved: (1) the centromeric-telomeric orientation of the whole region, (2) the relative orientation of the two contigs, and (3) the size of the gap between the two contigs. To provide a definitive answer to these questions, high-resolution mapping by fluorescence in situ hybridization on combed DNA and molecular approaches were combined to establish the physical map of the XLP region over 600 kb. Our results identified a gap of 150 kb between the two contigs, established the relative orientation of one contig to the other, and determine the centromeric-telomeric orientation of the whole region. Our results show that the order of the marker over this region is: cen.1D10T7-DF83-DXS982.tel.

B lineage-derived malignant proliferation is a well recognized complication of HIV infection. Acute myeloid leukemias have been reported but no complete review of these cases has been performed. The Medline database was reviewed for the years 1980-1997. Eighteen cases of AML have been reported. When previously known, HIV infection was present for 40 months. In 7 patients HIV infection and AML were diagnosed simultaneously. According to the FAB classification, 5 cases were M2, 8 M4, 5 M5. Extramedullary localizations (skin, testis, spleen) were noticed in 10 patients. Non-treated patients had a survival of 2.7 weeks versus 9.8 months in patients treated with chemotherapy. Pathophysiologic studies were performed in 3 cases: reverse transcriptase activity and p24 antigen were noted in tumoral cultured cells in 1 case; absence of viral particules in culture in another one; absence of cloned DNA provirus integration in blasts cells in a third patient. Based on the observed high rate of M4/M5 (72%) versus 19-36% expected in a non HIV-infected population, we postulate that the association of AML and HIV is not coincidental. The monocytotropism of HIV, the chronic cytokines-mediated activation of monocyte/macrophages, the immunodeficiency may explain this association.

Careful longitudinal studies of the lymphoid cell recovery after stem cell transplantation with other than HLA-identical sibling donors illustrated the prolonged T- and B-cellular immunodeficiency post-SCT, whereas NK-cell recovery was fast. Only low numbers of CD45RO memory T-cells, with a restricted TCR-repertoire, are present in the first 6 months post-SCT. The consequence is an increased risk of viral infections and possibly of leukemia relapse. The latter complication can be prevented by enhancing the anti-leukemic immune reactivity shortly after SCT. Different technical approaches were presented, the majority of them still being in the pre-clinical phase. NK-cell reactivity based on KIR-epitope mismatches between donor and recipient are promising for AML- and CML-, not for ALL-patients. The ALL-blasts may be killed by an antibody-dependent cellular cytotoxicity, using anti-CD19 antibodies, as was shown to be effective in vitro. Also the generation of leukemia-specific CTL's, making use of differences in minor histocompatibility antigens between donor and recipient, is now operational and may be a highly effective approach in a number of leukemic graft recipients.

Between March 1984 and December 1999, a total of 43 second related allogeneic BMT procedures after myeloablative conditioning were carried out in our institution, 37 following allogeneic, and 6 following autologous BMT. Thirty one patients were males (72%). At 1st BMT (BMT1), median age was 11.5 years (range, 0.16-45 years). BMT1 was carried out for the diagnosis of AML in 13 patients (30%), SAA in nine (21%), ALL in six (14%), CML in six (14%), immunodeficiency in three (7%), NHL in two, beta-thal in two, HD in one, Red cell aplasia in one. HLA matching status for allogeneic BMT1 was full match in 33, one antigen mismatch in two and haplo identical in two patients. Median age at the 2nd BMT (BMT2) was 14 years (range, 0.41-46.7 years). Indications for BMT2 were recurrent hematologic neoplasm in 23 patients (53%), primary graft failure in 12 (28%) and late graft failure in 8 (19%). Median time from BMT1 to recurrence of hematologic neoplasm or late graft failure was 10 months (range, 2.5- 88 months). Median BMT1 to BMT2 interval was 13 months (range, 1-107 months). For BMT2, the same donor was used in 29 patients, while 14 patients had alternate related donor (12 full match, 1-one Ag mismatch, 1 haplo identical). A different conditioning regimen was used in the majority of the patients (39, 91%). Radiation containing conditioning regimen were used mostly for patients previously conditioned with chemotherapy only for BMT1 and chemotherapy conditioning +/- ATG for those who received radiation containing conditioning at BMT1. Bone marrow was the stem cell source for all patients at BMT2 and all except three autologous peripheral stem cell transplantation patient at BMT1. Significant organ toxicity leading to procedure related death in 13 patients (30%) was observed after BMT2. At a median follow up of 36 months after BMT2, 22 patients (51%) are alive (20 free of disease, 2 with recurrent disease) with overall median survival of 47.5 (SD +/- 9) months. Univariate analysis of relevant clinical factors identified the following variables as the only statistically significant favorable prognostic factors for overall survival: BMT1-BMT2 interval of > or = 6 months (P=0.0007) and age at BMT2 < or = 10 years (P=0.041). The nature of underlying disease (neoplastic or non-neoplastic) was not statistically significant (P=0.23). There was no statistically significant difference in survival outcome of BMT2 using same donor vs. alternate related donor (P=0.51). Due to the relatively limited sample size, multivariate analysis was not attempted. This single institution study suggests that second allogeneic BMT after myeloblative conditioning has an acceptable treatment related morbidity/mortality and favorable outcome if performed at age < or = 10 years and with an interval of > or = 6 months after the first BMT. Additionally same donor can successfully be used for the second transplant with similar survival outcome to alternate donor.

Sex workers play a major role in spreading sexually transmitted infections (STIs). We studied the prevalence rates and risk factors for STIs among 300 brothel-based sex workers in Tel-Aviv. Throat swabs were cultured for Neisseria gonorrhoeae, urine samples were tested by polymerase chain reaction (PCR) for Chlamydia trachomatis and N. gonorrhoeae, and sera were tested for syphilis, human immunodeficiency virus (HIV) and type 2 herpes simplex virus (HSV) antibodies. N. gonorrhoeae was cultured from throat samples of 9.0% of participants; PCR testing of urine was positive for C. trachomatis in 6.3% and for N. gonorrhoeae in 5.0%. Syphilis serology was positive (Venereal Disease Research Laboratory [VDRL] titres > 1:8) in 1.3% of women, HSV-2-specific immunoglobulin G was detected in 60% and HIV serology was positive in a single case (0.3%). Having STI was significantly associated with age, number of years in Israel, number of clients a week and condom use for vaginal sex. In a multivariate analysis, having STI was significantly associated with number of clients per week and condom use for vaginal sex. The high prevalence of pharyngeal gonorrhoea reflects most probably the expanding demand of clients for oral sex and the insufficient condom use in this form of sex.

Chronic GVHD (cGVHD) associated bronchiolitis obliterans syndrome (BOS) is a serious complication after allo-SCT, and lung transplantation (LTx) may be the ultimate treatment option. To evaluate this treatment, data on all patients with LTx after allo-SCT ever performed in Sweden, Norway, Denmark and Finland were recorded and compared with survival data from the Scandiatransplant registry. In total, LTx after allo-SCT had been performed in 13 patients. Allo-SCT was done because of AML (n=6), CML (n=3), ALL (n=2), immunodeficiency (n=1) and aplastic anemia (n=1). All developed clinical cGVHD, with median interval from allo-SCT to LTx of 8.2 (0.7-16) years. Median age at LTx was 34 (16-55) years, and the median postoperative observation time was 4.2 (0.1-15) years. Two patients died, one due to septicemia, the other of relapsing leukemia, after 2 and 14 months, respectively. Four developed BOS, one of these was retransplanted. The survival did not significantly differ from the survival in matched LTx controls, being 90% 1 year and 75% 5 years after LTx compared with 85% and 68% in the controls. We therefore suggest that LTx may be considered in carefully selected patients with BOS due to cGVHD after allo-SCT.
