Myeloid disorders after autoimmune disease. Best Pract Res Clin Haematol 2019; 32:74-88.

Abstract
Autoimmune diseases (ADs) are associated with an increased risk not only of lymphoproliferative disorders but also of myeloid malignancies. The excess risk of myelodysplastic syndromes and/or acute myeloid leukemia is observed across several AD types, including systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disorders, multiple sclerosis, among others. The risk of developing myeloid neoplasms (MNs) is dependent on several variables, including the specific AD type, chronicity and severity of the AD, type and duration of exposure of disease modifying anti-rheumatic drugs or cytotoxics/immunosuppressives, and genetic predisposition risk. Putative triggering factors linking AD to elevated MN risk include AD-directed medications, shared genetic susceptibilities between the two disease entities, and chronic immune stimulation or bone marrow infiltration by the AD. Molecular mechanisms underpinning leukemogenesis remain largely speculative and warrant further investigation. Leukemias arising in patients with AD are not always 'therapy-related' in that MNs may develop in certain AD subtypes even among patients with no prior therapy exposure. Only a few studies have attempted to determine factors associated with MN development in AD but failed to demonstrate consistent characteristic clinical or paraclinical features. These reports have failed to demonstrate a clear correlation between individual agent exposure and subsequent leukemia development due to the low rates of therapy exposure compounded by the rarity of MN occurrence. Notwithstanding, the leukemogenic potential is best documented with agents such as azathioprine, cyclophosphamide, and mitoxantrone; this risk of MN development does not appear to be shared by biologic approaches such as anti-tumor necrosis factors-alpha inhibitors. In this article, we discuss plausible biologic mechanisms underlying MN pathogenesis in AD and review the data available on the development of MNs in patients with AD.

Abstract
Increased autoantibody reactivity in plasma from Myelodysplastic Syndromes (MDS) patients may provide novel disease signatures, and possible early detection. In a two-stage study we investigated Immunoglobulin G reactivity in plasma from MDS, Acute Myeloid Leukemia post MDS patients, and a healthy cohort. In exploratory Stage I we utilized high-throughput protein arrays to identify 35 high-interest proteins showing increased reactivity in patient subgroups compared to healthy controls. In validation Stage II we designed new arrays focusing on 25 of the proteins identified in Stage I and expanded the initial cohort. We validated increased antibody reactivity against AKT3, FCGR3A and ARL8B in patients, which enabled sample classification into stable MDS and healthy individuals. We also detected elevated AKT3 protein levels in MDS patient plasma. The discovery of increased specific autoantibody reactivity in MDS patients, provides molecular signatures for classification, supplementing existing risk categorizations, and may enhance diagnostic and prognostic capabilities for MDS.

Abstract
BACKGROUND The current appreciation of the biological complexity of disease has led to increasing demands on pathologists to provide clinically relevant, quantitative morphological and molecular information while preserving cellular and tissue context. This can be technically challenging, especially when signals of interest are colocalized. With fluorescence-based methods, sensitivity and quantitative reliability may be compromised by spectral cross-talk between labels and by autofluorescence. In brightfield microscopy, overlapping chromogenic signals pose similar imaging difficulties. APPROACH These challenges can be addressed using commercially available multispectral imaging technologies attached to standard microscope platforms, or alternatively, integrated into whole-slide scanning instruments. ASSESSMENT Multispectral techniques, along with other developments in digital analysis, will allow pathologists to deliver appropriate quantitative and multiplexed analyses in a reproducible and timely manner. Caveats apply - as the complexity of the sample preparation and analysis components increases, commensurate attention must be paid to the use of appropriate controls for all stages of the process.

Antiretroviral activity of 5-azacytidine during treatment of a HTLV-1 positive myelodysplastic syndrome with autoimmune manifestations. Virol J 2012; 9:1.

Abstract
Myelodysplastic syndromes (MDS) are often accompanied by autoimmune phenomena. The underlying mechanisms for these associations remain uncertain, although T cell activation seems to be important. Human T-lymphotropic virus (HTLV-1) has been detected in patients with myelodysplastic syndromes, mostly in regions of the world which are endemic for the virus, and where association of HTLV-1 with rheumatological manifestation is not rare. We present here the case of a 58 year old man who presented with cytopenias, leukocytoclastic vasculitis of the skin and glomerulopathy, and was diagnosed as MDS (refractory anemia with excess blasts - RAEB 1). The patient also tested positive for HTLV-1 by PCR. After 8 monthly cycles of 5-azacytidine he achieved a complete hematologic remission. Following treatment, a second PCR for HTLV-1 was carried out and found to be negative. This is the first report in the literature of a HTLV-1-positive MDS with severe autoimmune manifestations, which was treated with the hypomethylating factor 5-azacitidine, achieving cytogenetic remission with concomitant resolution of the autoimmune manifestations, as well as HTLV-1-PCR negativity. HTLV-1-PCR negativity may be due to either immune mediated clearance of the virus, or a potential antiretroviral effect of 5-azacytidine. 5-azacytidine is known for its antiretroviral effects, although there is no proof of its activity against HTLV-1 infection in vivo.

Abstract
Myelodysplastic syndrome (MDS) is known to be associated with functional abnormalities of B cells, including hypergammaglobulinemia and monoclonal gammopathy (MG). However, the pathogenesis of these immunological disorders has not been clarified. We report a patient who developed donor-derived MDS followed by leukemic transformation after cord blood transplantation for MDS with MG. Interestingly, MG reappeared before development of donor-derived MDS. We analyzed the immunoglobulin allotype gene polymorphisms to determine whether the MG after cord blood transplantation was of recipient origin or donor origin. Results of genetic analysis and enzyme-linked immunosorbent assay of IgG1 allotype revealed that the MG after cord blood transplantation was of donor origin. Although the mechanism of donor-derived MG remains unclear, the persistent presence of recipient's antigen presenting cells might have induced the abnormal immunoglobulin production.

Abstract
During disease progression in myelodysplastic syndromes (MDS), clonal blasts gain a more aggressive nature, whereas nonclonal immune cells become less efficient via an unknown mechanism. Using MDS cell lines and patient samples, we showed that the expression of an immunoinhibitory molecule, B7-H1 (CD274), was induced by interferon-gamma (IFNgamma) and tumor necrosis factor-alpha (TNFalpha) on MDS blasts. This induction was associated with the activation of nuclear factor-kappaB (NF-kappaB) and nearly completely blocked by an NF-kappaB inhibitor, pyrrolidine dithiocarbamate (PDTC). B7-H1(+) MDS blasts had greater intrinsic proliferative capacity than B7-H1(-) MDS blasts when examined in various assays. Furthermore, B7-H1(+) blasts suppressed T-cell proliferation and induced T-cell apoptosis in allogeneic cocultures. When fresh bone marrow samples from patients were examined, blasts from high-risk MDS patients expressed B7-H1 molecules more often compared with those from low-risk MDS patients. Moreover, MDS T cells often overexpressed programmed cell death 1 (PD-1) molecules that transmit an inhibitory signal from B7-H1 molecules. Taken together, these findings provide new insight into MDS pathophysiology. IFNgamma and TNFalpha activate NF-kappaB that in turn induces B7-H1 expression on MDS blasts. B7-H1(+) MDS blasts have an intrinsic proliferative advantage and induce T-cell suppression, which may be associated with disease progression in MDS.

Abstract
Progressive multifocal leukoencephalopathy (PML) is a rare and fatal demyelinating disease of the central nervous system caused by JC polyomavirus (JCV) reactivation in an immunocompromised host. We describe a case of PML in a 76-year-old woman with myelodysplastic syndrome, who had been treated with azathioprine for a pure red cell aplasia-like condition. PML was diagnosed based on the neurologic symptoms, the magnetic resonance imaging patterns and the detection of JCV DNA in the cerebrospinal fluid. She died ten months after the diagnosis. An autopsy confirmed the diagnosis, and JCV DNA was detected in the cerebrum. Azathioprine might have triggered PML.

Abstract
It is often difficult to distinguish myelodysplastic syndrome (MDS) from aplastic anemia (AA) because of the considerable clinical, cytologic histologic similarities between these two disorders; however, distinguishing between AA and MDS is of great importance because there is a higher risk of progression to acute leukemia in patients with MDS compared with AA. Up to now, CD34(+) cells in MDS and AA patients have been studied extensively; however, little information is available on myeloid granulocytes. The aim of this study was to determine whether immunophenotype of myeloid granulocytes in AA patients was different from that of MDS. Flow cytometry was used to assess the immunophenotype of myeloid granulocytes in 22 patients with MDS, 12 with AA, and 10 normal subjects. Our data showed that the percentages of CD13(+) granulocytes, CD33(+) granulocytes, CD34(+) granulocytes, and HLA-DR(+) granulocytes were significantly higher in patients with MDS than in AA patients and normal subjects (P < 0.05). The percentages of CD15(+) granulocytes and CD10(+) granulocytes were significantly lower in patients with MDS than in AA patients and normal subjects (P < 0.05). There were no significant differences in the expression of these markers between patients with AA and normal subjects (P > 0.05). As refractory anemia progressing to refractory anemia with excess blasts, the percentages of CD13(+) granulocytes, CD33(+) granulocytes, CD34(+) granulocytes and HLA-DR(+) granulocytes were significantly increased, whereas, the percentage of CD15(+) granulocytes was significantly decreased (P < 0.05). These data suggest that immunophenotype of myeloid granulocytes may be a useful parameter for the differential diagnosis of MDS and AA.

Abstract
Expression of a NUP98-HOXD13 (NHD13) fusion gene leads to myelodysplastic syndrome in mice. In addition to ineffective hematopoiesis, we observed that NHD13 mice were lymphopenic; the lymphopenia was due to a decrease in both T and B lymphocytes. Although the pro-B cell (B220(+)/CD43(+)) populations from the NHD13 and wild-type mice were similar, the NHD13 mice showed decreased pre-B cells (B220(+)/CD43(-)), indicating impaired differentiation at the pro-B to pre-B stage. Thymi from NHD13 mice were smaller and overexpressed Hoxa cluster genes, including Hoxa7, Hoxa9, and Hoxa10. In addition, the NHD13 thymi contained fewer thymocytes, with an increased percentage of CD4(-)/CD8(-) (double-negative (DN)) cells and a decreased percentage of CD4(+)/CD8(+) (double-positive) cells; the DN1/DN2 population was increased and the DN3/DN4 population was decreased, suggesting a partial block at the DN2 to DN3 transition. To determine clonality of the thymocytes, we used degenerate RT-PCR to identify clonal Tcrb gene rearrangements. Five of six NHD13 thymi showed an unusual Tcrb gene rearrangement pattern with common, clonal DJ rearrangements, but distinct V-D junctions, suggesting a marked clonal expansion of thymocytes that had undergone a DJ rearrangement, but not completed a VDJ rearrangement. Taken together, these findings demonstrate that expression of the NHD13 transgene inhibits lymphoid as well as myeloid and erythroid differentiation, results in overexpression of Hoxa cluster genes, and leads to a precursor T cell lymphoblastic leukemia/lymphoma.

Abstract
To better estimate prognosis for patients with myelodysplastic syndromes (MDS) associated with clonal interstitial deletions of the long arm of chromosome 5 (del(5q)), we reviewed the medical records of 130 adults with del(5q) MDS seen at our institution over a 15-year period. Overall median survival of this cohort was 9.5 months, shorter than reported in earlier series. The least favorable outcomes are associated with complex cytogenetics, lack of any normal metaphases, normocytic rather than macrocytic erythrocyte indices, and low baseline lymphocyte counts. Lymphopenia but not neutropenia at the time of diagnosis appears to be a new adverse prognostic indicator. Cytogenetic breakpoints defined by G-banded karyotyping correlate poorly with particular disease features. Surprisingly, survival of patients with treatment-related MDS was equivalent to that of de novo MDS with del(5q) in this series. Morphologic features associated with del(5q) are diverse. Most patients with del(5q) MDS do not meet criteria for WHO-defined 5q-syndrome, and the presence of del(5q) does not appear to modify the clinical phenotype otherwise risk-stratified by the International Prognostic Scoring System (IPSS). Additional important prognostic factors not taken into account by the IPSS include the baseline erythrocyte indices, lymphocyte count, and clonal burden.

Abstract
Relapsing polychondritis is an autoimmune disease that primarily manifests as cartilaginous tissue destruction. However, the immune impairment may also involve noncartilaginous tissues such as kidneys, blood vessels, etc. The disease may occur as a primary disorder or in association with other diseases. The case of a female patient with concurrent manifestation of myelodysplastic syndrome-refractory anemia with excess blasts, and relapsing polychondritis, is presented. The diagnosis of relapsing polychondritis was established ten months after the diagnosis of myelodysplastic syndrome, when the criteria for the former were met. Total hearing loss and blindness developed soon thereafter.

Abstract
The mechanism of T cell lymphopenia in myelodysplastic syndromes (MDS) is unknown. We investigated apoptosis in freshly isolated and cultured lymphocytes; the latter were used to detect cells not yet apoptotic but destined for apoptosis. Apoptosis increased in both fresh and cultured T cells in MDS compared with those from healthy controls. Furthermore, in lymphopenic MDS patients the lymphocyte count correlated negatively with the degree of T cell apoptosis. MDS T cells showed increased Fas expression. However, in MDS but not in controls, the degree of T cell apoptosis was independent of the Fas expression level, and exogenous anti-Fas antibodies did not modulate T cell apoptosis. Mechanisms other than the Fas-Fas ligand pathway may induce T cell apoptosis in MDS.

Abstract
Myelodysplastic syndromes (MDS) are common malignant disorders with a poor prognosis. MDS are a group of highly heterogeneous disorders but show certain universal findings including a high incidence in the elderly population, cytopenia, dysplastic myeloid cells, and frequent transformation to acute myeloid leukemia. Until recently, the vast majority of MDS patients were treated with supportive therapy alone, such as transfusions. Allogeneic stem cell transplantation (SCT) has the potential for cure, although due to the age and comorbidity of MDS patients, the role of allogeneic SCT in MDS has been limited. Recently, research in MDS has shown substantial advances that have deepened our understanding of MDS pathophysiology and changed our approach to MDS patients. This review touches on some recent developments in the diagnosis and pathophysiology of MDS.

Abstract
The chromosomal translocation t(12; 22)(p13;q11) in human myeloid leukemia generates an MN1-TEL (meningioma 1-translocation-ETS-leukemia) fusion oncoprotein. This protein consists of N-terminal MN1 sequences, a transcriptional coactivator fused to C-terminal TEL sequences, an ETS (E26 transformation-specific) transcription factor. Enforced expression of MN1-TEL in multipotent hematopoietic progenitors in knock-in mice perturbed growth and differentiation of myeloid as well as lymphoid cells. Depending on obligatory secondary mutations, these mice developed T-cell lympholeukemia. Here we addressed the role of MN1-TEL in myeloid leukemogenesis using the same mouse model. Expression of MN1-TEL enhanced the growth of myeloid progenitors in an interleukin 3/stem cell factor (IL-3/SCF)-dependent manner in vitro whereas 10% of MN1-TEL-expressing mice developed altered myelopoiesis with severe anemia after long latency. Coexpression of MN1-TEL and IL-3, but not SCF, rapidly caused a fatal myeloproliferative disease rather than acute myeloid leukemia (AML). Because MN1-TEL+ AML patient cells overexpress HOXA9 (homeobox A9), we tested the effect of coexpression of MN1-TEL and HOXA9 in mice and found that 90% of MN1-TEL+/HOXA9+ mice developed AML much more rapidly than control HOXA9+ mice. Thus, the leukemogenic effect of MN1-TEL in our knock-in mice is pleiotropic, and the type of secondary mutation determines disease outcome.

Abstract
Myelodysplastic syndrome (MDS) comprises a group of clonal haematopoietic disorders characterized by peripheral blood cytopenias, bone marrow hypercellularity, and abnormal blood cell differentiation. Approximately 30% of cases of MDS eventually progress to acute myelogenous leukemia (AML), while progression of MDS into acute lymphoblastic leukemia (ALL) is rare. In this report, we describe a case of MDS that progressed to ALL, and review the 21 previously reported cases of MDS to ALL transformation. We review the cancer stem cell model and its application to these disorders, and discuss the implications of the rarity of transformation of MDS to ALL for the biology of MDS and the pathogenesis of ALL.

Abstract
Antithymocyte globulin (ATG) has recently been popularized as an effective treatment in myelodysplastic syndrome (MDS). We treated 8 anemic MDS patients (refractory anemia [RA] and refractory anemia with excess blasts [RAEB-1]) with ATG (40 mg/kg/d for 4 days) and prednisone in a phase 2 trial. The study was stopped early according to a preset termination rule because of lack of efficacy. There were no salutary responses. Toxicities included serum sickness (in all patients), transient neutropenia and thrombocytopenia, diarrhea, vomiting, and syncope with a generalized seizure. At least 3 patients had the HLA-DR15 (DR2) allele. We conclude that the risk-benefit ratio of ATG in an unselected population of MDS patients may be unfavorable, and more work is needed to define the subset of patients who will respond to ATG before its widespread use can be recommended.

Abstract
Modern therapeutic strategies for the treatment of acquired aplastic anemia are based on the current understanding of its pathophysiology as well as empiric observations. Most cases of aplastic anemia appear to be the result of immune-mediated destruction of hematopoietic cells, which can be approached by stem cell transplantation in younger patients with appropriate histocompatible donors or by immunosuppression to reduce T-cell activity. Popular treatment regimens combine antithymocyte globulin with cyclosporine. Although a majority of patients respond with improved blood counts and achieve transfusion-independence, late clonal complications of myelodysplasia and cytogenetic abnormalities occur in a substantial minority of cases. Additionally, there is no clear algorithm for the treatment of refractory disease. Newer methods of treatment, including high-dose cyclophosphamide and the development of potentially tolerizing combinations of drugs. are under study. Effective therapies for aplastic anemia might also be applied to other T-cell mediated, organ-specific human diseases.

Abstract
OBJECTIVE To determine the clinical aspects of systemic vasculitis associated with chronic myelomonocytic leukemia (CMML). METHODS In this retrospective study, 8 patients suffering from systemic vasculitis associated with CMML are described. The French and English literature on systemic vasculitis associated with myelodysplasia was reviewed. RESULTS All 8 patients had a systemic medium-sized vessel vasculitis which fulfilled the American College of Rheumatology criteria for polyarteritis nodosa in the setting of active CMML. Antineutrophil cytoplasmic antibodies (ANCA) were negative in 7 patients. One patient had cytoplasmic ANCA by indirect immunofluorescence without antiproteinase 3 or antimyeloperoxydase antibodies on the enzyme-linked immunosorbent assay. At presentation, 6 patients had fever of unknown origin, 5 had polymyalgia rheumatica, 3 had sensory hearing loss, and 4 had eosinophilia. None had viral infection or drug-associated vasculitis. Diagnostic procedures included renal or hepatic angiography in 6 patients which showed microaneurysms in 4, skin and temporal artery biopsy in 2 which showed vasculitis, and 1 postmortem examination which showed gastroduodenal arteritis. All patients were treated with corticosteroids, and 7 received immunosuppressive drugs. Death was attributable to vasculitis in 2 cases, infection in 3, and other vasculitis-related causes in 2. In a review of the French-English literature, we found 11 similar cases of ANCA-negative systemic vasculitis, generally associated with refractory anemia, with or without blast excess. CONCLUSIONS Systemic ANCA-negative polyarteritis nodosa-type vasculitis seems closely associated to CMML. Clinical presentation is nonspecific, and systemic vasculitis should be suspected when a patient with myelodysplasia develops atypical manifestations. Renal, gastrointestinal, or hepatic angiography are useful diagnostic procedures when more invasive biopsies should be avoided because of low platelet count. The prognosis of CMML-associated systemic vasculitis is poor.

Abstract
BACKGROUND Immunodeficiency in pediatric patients with myelodysplastic syndrome (MDS) has not been described. We report the clinical course of three children with MDS, hypogammaglobulinemia, and reduced numbers of B-cells and B-cell precursors. OBSERVATIONS Three patients with recurrent infection who were younger than 1-year-old had MDS of the refractory anemia (RA) subtype diagnosed. All had reduced numbers of circulating B-cells and hypogammaglobulinemia. In two patients, cytogenetic studies revealed a monosomy 7 karyotype and bone marrow studies showed decreased numbers of CD34+ progenitor cells and CD 19+ B-cells. Both patients had prolonged courses (7 yrs 10 mos and 6 yrs 9 mos) characterized by recurrent infection and slowly progressive pancytopenia. Both received allogeneic bone marrow transplantation (BMT). The third patient had normal cytogenetic studies and a normal number of CD34+ progenitors but decreased CD19+ B-cells in the bone marrow. She had a stable course with refractory anemia over the course of 7 years. CONCLUSIONS Pediatric patients with MDS may have hypogammaglobulinemia and reduced numbers of B-cells. These findings do not preclude a relatively stable and prolonged clinical course. Children with newly diagnosed MDS should have an immunologic evaluation in addition to their hematologic assessment.

Abstract
The first case of B-cell lymphoma of brain in a patient with myelodysplastic syndrome (MDS) was reported. A 68-year-old man was admitted because of anemia, fever, and thrombocytopenia and was diagnosed as having MDS (refractory anemia with excess of blasts) on the basis of the findings of bone marrow aspiration and chromosomal analysis. The patient was followed up without chemotherapy, but a brain tumor appeared after 3 years. Histologic and immunohistologic examinations revealed diffuse large B-cell lymphoma. Mutations of the c-kit proto-oncogene (stem cell factor receptor) and the p53 tumor-suppressor gene were examined in the MDS lesion and malignant lymphoma (ML) by the polymerase chain reaction-single-strand conformational polymorphism (PCR-SSCP) method followed by direct sequencing. The p53 mutation was not found in either MDS or ML, but a nonsense mutation (Try-557 --> stop) in exon 11 of the c-kit, which might lead to dysfunction of tyrosine kinase activity, was detected in MDS. This is the first report of c-kit mutation in MDS. Epstein-Barr virus (EBV) genome was demonstrated in the nucleus of brain ML cells by in situ hybridization with EBV-encoded RNA-1 probe. Immunohistochemistry showed that the tumor cells expressed latent infection gene products, including EBV nuclear antigen-2 and latent membrane protein-1. This pattern of latent gene expression was Lat III, which is usually found in malignant lymphomas developing in immunocompromised hosts. These findings suggest that a profound pancytopenia in MDS resulted in an immunodeficient condition, after which EBV-positive B-cell lymphoma of brain developed.

Abstract
Non-caseating granuloma (NCG) remains a histopathological hallmark for sarcoidosis. Although the exact mechanism for NCG formation is unknown, the pathogenesis may involve a disordered antigen presentation in the monocyte/macrophage system, functional abnormalities in activated T-lymphocytes and uncontrolled cytokine production. Similar immunological dysfunction has been described in myelodysplastic syndrome (MDS). However, the association of NCG and MDS is rarely documented. We report a case of hypocellular MDS associated with generalized NCG. Despite treatment for both sarcoidosis and tuberculosis, the patient failed to respond. A clonal myeloid disorder which was initially suppressed by T-cell immunosurveillance evolved after treatment with anti-thymocyte globulin. Although the coexistence of sarcoidosis remains a possibility, the lack of supportive clinical evidence of sarcoidosis, the abnormal appearances of the bone marrow, together with the failure to improve on high-dose steroid favour the clonal myeloid disorder as the sole pathology.

Abstract
Benign nodular lymphoid lesions are not rare in the bone marrow of patients with myelodysplastic syndrome (MDS). Herein, we report a case of MDS with clonal lymphoid aggregates in the bone marrow but without evidence of systemic lymphoma. The case of a 71-year-old man was evaluated for cytopenia. His bone marrow was initially hypocellular, with 10% blasts and a few small lymphoid aggregates. The diagnosis of refractory anemia with excess blasts was made. The disease progressed gradually, and he received erythropoietin and granulocyte colony-stimulating factor for a short time. Forty-two months later, acute leukemia (M1) developed, with 60% to 70% blasts in the bone marrow. The bone marrow also showed large aggregates of lymphocytes. Immunohistochemical study of these cells in the nodular lesions showed 50% CD3+ and 50% CD20+. Cytogenetic and molecular genetic studies revealed monosomy 7 and T- and B-cell clonal gene rearrangement. Fluorescent in situ hybridization study with centromere-specific probes of a bone marrow specimen showed monosomy 7 in both nodular lymphoid lesions and surrounding bone marrow cells, indicating that both processes originated from the same abnormal pluripotential progenitor.

Abstract
Patients with myelodysplastic syndromes (MDS) show a decrease in the number and function of natural killer (NK) cells, including lymphokine activated killer (LAK) cell activity. Interleukin-2 (IL-2) stimulates the proliferation and activity of these lymphocytes. Anecdotal clinical experience has shown haematological and cytogenetic improvement in myelodysplasia by low-dose IL-2 treatment. A total of 10 patients with MDS were treated with 1 million units of IL-2 subcutaneously daily for 12 weeks. Even though improvement in CD16+/CD56+ cell numbers was seen in a majority of the patients, the haematological status and transfusion requirements remained unchanged. There was minimal toxicity from this therapy.

Abstract
Previous studies on neutrophils in patients with the myelodysplastic syndromes (MDS) have indicated deficiencies in the contents of primary and secondary granules. However, the granule membrane remains virtually unstudied despite its essential role in the dynamic function of the cytoplasmic granules. In this study, we examined the membrane glycoproteins of primary and secondary granules of peripheral blood and/or bone marrow neutrophils using the monoclonal antibody H36/71 to CD15 glycoproteins. In addition, myeloperoxidase activity and antigen, elastase and lactoferrin were also studied using cytochemical and immunocytochemical stains. A total of 216 patients were included. Deficiencies of granule membrane glycoproteins were the most common, detected in 49%, followed by myeloperoxidase activity (17%), elastase (16%), myeloperoxidase antigen (9%), and lactoferrin (8%). Multiple deficiencies always included granule membrane deficiency. We conclude that granule membrane defects are common in MDS, may provide a common mechanism for multiple granule deficiencies, and may prove to be an additional abnormality associated with granulocyte dysfunction.

Abstract
A Phase II clinical trial was undertaken using roquinimex (Linomide) in patients with myelodysplastic syndromes (MDS). Roquinimex is an orally active drug with immunostimulating activities demonstrated in vitro and clinically. Seventeen patients with MDS were enrolled in the study. Eligibility was limited to cytopenic patients with <20% marrow blasts. The drug was given orally twice weekly for 12 weeks with frequent monitoring of clinical, hematologic, and immunologic parameters. An increase in CD8+ and CD56+/CD3- cells was detected by 3 weeks. There was, however, no augmentation of natural killer or lymphokine-activated killer cell activity; progenitor cells were unchanged. Four patients had improvement in neutrophil counts, and two patients had improvement in platelet counts. Despite this improvement, the responses were transient or not maintained after discontinuation of therapy. One patient with RAEB, who was red cell transfusion dependent, experienced a complete remission that has persisted 14 months after completion of therapy. Adverse events developed in >25% of patients and included arthralgia, fever, headache, and myalgia. These side effects led to early withdrawal of therapy in five patients. These findings suggest that roquinimex may be of occasional benefit to patients with myelodysplastic syndromes.

Abstract
Myelodysplastic syndromes (MDS) are characterized by quantitative and functional involvement of myeloid lineages. Yet, systemic manifestations, suggestive of a lymphocytic involvement, have been described in MDS. We review here biological and clinical data concerning the associations between MDS and immunological disorders. Biological auto-immune markers are in fact rare in MDS, and especially encountered in the chronic myelomonocytic leukemia subgroup. Only a few systemic diseases seem to be frequently associated with MDS: seronegative arthritis, cutaneous vasculitis, and relapsing polychondritis. These diseases are probably not entirely auto-immune, and the signification of their association with an MDS remains unclear. About 30% of relapsing polychondritis are associated with MDS. Conversely, 0.6% of MDS are associated with a relapsing polychondritis. These associations are mainly encountered in men suffering from a refractory anemia (with or without excess of blasts). The main cytogenetic abnormalities are monosomy 7, presence of a ring chromosome, and monosomy 16.

Abstract
BACKGROUND Over a 15 year period, the authors followed 51 male patients with myelodysplastic syndromes whose clinical findings, laboratory data, and evolution demonstrated a wide spectrum of disease. METHODS The following characteristics were assessed: age at diagnosis, risk factors, clinical presentation, laboratory features, category of myelodysplasia, leukemic conversion, and overall survival. RESULTS The clinical manifestations included hemolytic episodes in two patients, antibody-mediated thrombopenia in one, marked marrow fibrosis in two; thrombocytosis in three, and simultaneous lymphoproliferative disorders in two. There were 21 patients whose marrow was either normo- or hypocellular. Six patients presented with single cytopenia but not anemia. There were six instances of overlapping of the French-American-British classification. Eighteen patients progressed to acute leukemia and 1 to chronic myelomonocytic leukemia. CONCLUSIONS These observations indicate that patients with myelodysplastic syndromes may have single cytopenia without anemia that progresses to acute leukemia and may, rarely, evolve into chronic myelomonocytic leukemia. The clinical aspects of these syndromes may include autoimmune phenomena and myeloproliferative features.

Abstract
Among 825 cases of de novo myelodysplastic syndromes (MDS) diagnosed over a period of 13 years in our center, 4 had clinically significant glomerulopathy. All 4 fulfilled diagnostic criteria of chronic myelomonocytic leukemia (CMML), and could be classified in the low or intermediate risk groups according to two scoring systems. Presenting symptoms of renal involvement were edema in 3 cases and acute renal failure in the remaining patient. Three patients had the nephrotic syndrome. Renal biopsy (performed in 2 cases but considered as contraindicated in the other cases) showed AL amyloidosis on one case and extracapillary glomerulonephritis in the other case. The 4 patients were treated with V16 or hydroxyurea and two had renal improvement. Only one previous case of MDS associated with glomerulopathy has been reported before and also very probably had CMML. This, and the response of renal disease to chemotherapy in 2 of our patients suggests a possible relationship between the two disorders. More systematic investigation of glomerular function, in CMML, could possibly disclose a higher incidence of cases of glomerular injury in this type of MDS.

Abstract
It has been recognized in recent years that some patients with myelodysplastic syndromes (MDS) develop immune-mediated complications (IMC), but little is known about the correlations to MDS-specific disease features. In a retrospective study of 82 MDS patients, we identified 10 (12%) with IMC (group A) and compared them to the remaining 72 cases (group B). Group A consisted of 5 patients with biopsy-verified skin vasculitis and 1 case each with temporal arteritis/polymyalgia rheumatica, necrotising panniculitis, Hashimoto's thyroiditis, autoimmune thrombocytopenia, and Sweet's syndrome. Survival times, sex ratio and distribution of MDS subtypes were similar in the two groups. The patients in group A were younger than those in group B (median 66 vs. 76 years, p < 0.01). Four patients (40%) in group A had a history of previous genotoxic therapy for malignant disorders. The bone marrow karyotype was evaluated in 62 patients. Clonal chromosomal abnormalities were found more frequently in Group A than in group B (8/9 vs. 26/53, p = 0.03), and complex karyotypes, i.e., three or more aberrations, were also observed to be more common in group A (3/9 vs. 8/53). The results indicate that IMC preferentially develop in patients with secondary MDS, in younger MDS cases, and in patients with cytogenetic abnormalities.

Abstract
This work describes the development of sideroblastic anemia (SA) during the clinical activity of systemic lupus erythematosus (SLE) in two patients. The cases refer to two women with SLE who developed SA during a relapse of the illness. Both patients fulfilled at least four criteria of the American Association of Rheumatology for SLE. In one patient, the treatment with prednisone was followed by the resolution of the SLE activity and the disappearance of the SA. Several years later there was no evidence of ringed sideroblasts or malignancy in the bone marrow. In the other patient, the clinical activity of the SLE and SA developed during the beginning of a septicemic event which finally led to her death. Our clinical cases allow us to show that the transitory development of SA can occur during a period of clinical activity of SLE and that its association, although infrequent, is due to a common physiopathogenic mechanism.
