A case of leukemia cutis (LC) of monocytic lineage in a patient with
myelodysplastic syndrome
(
MDS
) is presented. Cutaneous infiltrates were recognized concurrent with diagnosis of refractory anemia (RA) with monocytosis. Skin infiltrates subsequently spontaneously regressed although
MDS
progressed with increasing monocytosis, anemia, and thrombocytopenia. Death occurred 6 months after diagnosis with evolution of acute monoblastic leukemia complicated by
sepsis
. This case supports previous observations of poor prognosis associated with leukemia cutis. LC associated with
MDS
is reviewed including the role of monocytes.

We describe our experience of setting up an allogeneic BMT program at the Christian Medical College Hospital, Vellore over a period of 13 years, from October 1986 to December 1999. Two hundred and twenty-one transplants were performed during this period in 214 patients, with seven patients undergoing second transplants. Indication for BMT were thalassemia major - 106 (48%), CML - 30, AML - 35, ALL - 10, SAA - 22,
MDS
- six and six for other miscellaneous disorders. The mean age of this patient cohort was 15.6 years (range 2-52). Graft-versus-host disease of grades III and IV was seen in 36 patients (17%) and this was the primary cause of death in 20 patients (9.2%). All patients and donors were CMV IgG positive.
Sepsis
was the primary cause of death in 16 patients (7.4%), 10 bacterial, four fungal and two viral. One hundred and ten of this series of patients are alive and disease free (50%) with a median follow-up of 24 months (range 2-116). These results are comparable to those achieved for patients with similar disease status in transplant units in the Western world and cost a mean of US$15 000.

Several reports have documented various forms of glomerular diseases in adults with
myelodysplastic syndromes
(
MDS
), but similar reports in children are lacking. We describe two children with
MDS
-associated steroid-responsive nephrotic syndrome (NS). Patient 1, who had
MDS
with myelofibrosis, presented with hepatosplenomegaly, pancytopenia, chronic hepatitis, moderate proteinuria, hypocomplementemia and elevated ANA titer. During initial prednisone treatment proteinuria markedly diminished and partial but transient hematological improvement occurred. Relapse subsequently occurred that manifested by overt NS and pancytopenia. High doses of prednisolone led to remission of the renal disease, but hematological remission did not occur. Persisting pancytopenia and repeated infections terminated in
sepsis
, 2 years after the onset of the
MDS
. Patient 2, who had refractory anemia with clonal monosomy 19, presented with bowel disease, hepatosplenomegaly, anemia and non-organ-specific autoantibodies. Prednisone led to both clinical and hematological remission. The hematologic disease relapsed 12 months later, when nephrotic-range proteinuria, hematuria and mild azotemia were also found. Corticosteroid treatment led to long-lasting renal and hematologic remission, maintained by a small dosage of prednisone. In both patients, renal biopsy findings were consistent with those seen in idiopathic NS. A Medline search disclosed 16 cases of glomerulopathy in the course of
MDS
in adult patients. Clinical features included NS, usually accompanied by renal insufficiency with acute, chronic, or rapidly progressive glomerulonephritis. On biopsy, membranous nephropathy, crescentic or mesangial proliferative glomerulonephritis, and AL amyloidosis were found. We conclude: (1) that glomerular disease may be present and should be searched for in patients with
MDS
and (2) that
MDS
can be added to the list of rare conditions associated with corticosteroid-responsive NS in children.

Glycogen storage disease (GSD) is a rare autosomal-recessive disorder characterized by hypoglycemia, hepatosplenomegaly, seizures, and failure to thrive in infants. Neutropenia and/or neutrophil dysfunction develops in GSD1b, but not in other types. GSD1b results from a deficiency of the glucose-6-phosphate translocase enzyme and the genetic defect maps to chromosome 11q23. Patients with GSD1b are susceptible to recurrent bacterial infections, commonly involving the perirectal area, ears, skin, and urinary tract, although life-threatening infections, such as
septicemia
, pneumonia, and meningitis occur less frequently. Although the exact mechanism of neutropenia in patients with GSD1b is not known, treatment with recombinant human granulocyte colony-stimulating factor (G-CSF) has reduced the incidence of infections and has improved the quality of life of these patients. Defects in neutrophil chemotaxis and intracellular bacterial killing have been described and appear to be corrected by the use of G-CSF. To date, no cases of
myelodysplasia
or acute myeloid leukemia have been observed in patients with GSD1b treated with G-CSF. A significant complication of cytokine therapy is the development of hypersplenism, requiring either a reduction in the dosage of G-CSF or splenectomy.

To better define the incidence and causes of canine pancytopenia, we retrospectively evaluated the results of complete blood counts submitted to the University of Minnesota Veterinary Teaching Hospital during a 1-year period. Pancytopenia was defined as packed cell volume < 36%, total leukocyte count < 6,000/microliter or total segmented neutrophil count < 3,000/microliter, and platelet count < 200,000/microliter. Of 4,560 complete blood counts, 110 (2.4%) samples from 51 dogs met the criteria for pancytopenia. Eleven different disease processes were identified. These included chemotherapy-associated pancytopenia (n=22), parvovirus infection (n=5), malignant histiocytosis (n=5), idiopathic aplastic anemia (n=3),
sepsis
(n=3),
myelodysplastic syndrome
(n=3), immune-mediated hematologic disease (n=3), lymphoblastic leukemia (n=2), ehrlichiosis (n=2), estrogen toxicity (n=2), and multiple myeloma (n=1). Malignant histiocytosis and idiopathic aplastic anemia occurred more frequently than was expected. Doxoruicin was the chemotherapeutic agent associated with pancytopenia. Hematologic recovery and patient survival time varied with the cause of pancytopenia; therefore, a specific diagnosis was essential for establishing prognosis. Differentiation among causes of pancytopenia requires a systemic approach that includes elimination of infectious and drug-induced causes, and examination of bone marrow aspiration and core biopsy specimens.

We describe a very rare case of a patient who presented with red cell aplasia that later developed into myeloproliferation with
myelodysplasia
and eventually leukemia. A 63-year-old man presented with anemia and reticulocytopenia in May 1997. A bone marrow examination revealed erythroid aplasia with normal production of myeloid cells and megakaryocytes with a normal karyotype. After the diagnosis of pure red cell aplasia was made, the patient was treated with prednisolone and then with cyclosporin A (CyA). Two weeks after the initiation of CyA treatment, the peripheral reticulocyte count began to increase with a regrowth of erythroid cells in the bone marrow. Meanwhile, the peripheral white blood cell and platelet counts also increased to more than 10,000/microL and 1,000,000/microL, respectively. Examination of a bone marrow aspirate in December 1997 revealed myelodysplastic changes with trisomy 8. Despite the discontinuation of CyA and the administration of 1-beta-D-arabinofuranosylcytosine stearyl monophosphate, leukemia developed in August 1998. In September 1998, the patient died of
sepsis
during a neutropenic period that followed remission-induction therapy. In the mechanism of pathogenesis, CyA may induce upon pure red cell aplasia a secondary myeloproliferative disorder with
myelodysplasia
and leukemia. An alternative possibility is that CyA reduces autoimmune-mediated suppression of the underlying stem cell disorder and that the result of this reduction is the manifestation of myeloproliferation and leukemia.

We report a patient with longstanding Crohn's disease (CD) developing recurrent
sepsis
and impaired neutrophil function tests. His inflammatory bowel disease was controlled with local steroids and sulfasalazine with only short exposure to azathioprine. His blood counts remained within normal range, but the marrow showed mild dysplasia. Repeated cytogenetic examinations revealed trisomies 8 and 9, which are typical for therapy related
myelodysplasia
. Fluorescent in situ hybridization (FISH) study showed stable persistent trisomies, confined to the myeloid lineage, one year after discontinuation of sulfasalazine. The long-term use of immunodulating agents in patients with CD is not without risks, and early therapy related
myelodysplasia
might not be easily detected by blood count and morphology assessment alone.

The impressive anti-inflammatory effects of the tumor necrosis factor (TNF)alpha blockers etanercept and infliximab have led to their use in multiple inflammatory diseases besides their original indication, rheumatoid arthritis (RA). The well-studied clinical effects of both agents in RA are the reduction of signs and symptoms of joint inflammation as well as the arrest of bone destruction. Infliximab has also been Food and Drug Administration-approved in the treatment of Crohn disease; etanercept is now FDA-approved for juvenile chronic arthritis and psoriatic arthritis. Favorable initial clinical trials have been reported in other rheumatic diseases, including ankylosing spondylitis and adult Still disease. In addition, TNF alpha blockade is being studied in the treatment of uveitis,
myelodysplastic syndromes
, and graft-versus-host disease. Studies in
sepsis
and septic shock have identified small subsets of patients that may benefit from TNF alpha blockade, but broader use in septic patients has not improved survival. The TNF alpha blockers have had relatively infrequent serious side effects, especially compared with the immunosuppressive and cytotoxic agents otherwise employed to treat these diseases. Further studies of optimal dosing, combination with other therapies, and long-term benefits and side effects will emerge from future trials.

A 62-year-old man diagnosed with acute myelogenous leukemia which had developed from
myelodysplastic syndrome
received cytarabine and idarubicine as an induction therapy. The patient developed pneumonia and bacterial
sepsis
during profound neutropenia. Fever and
sepsis
improved by using many anti-bacterials and anti-fungals but he became febrile again and complained of severe lumbar pain. 67Ga scintigram showed abnormal uptake in the lumbar vertebra and left sternoclavicular joint, suggesting a diagnosis of discitis and osteomyelitis in the lumbar vertebra and sternoclavicular arthritis. We biopsied the site several times but culture of the biopsy specimen could not isolate any pathogens, and high fever persisted for about 10 months despite administration of various anti-bacterials and anti-fungals. Finally we inserted a catheter into the abscess at the iliopsoas muscle and Scedosporium apiospermum was isolated in the bloody pus obtained from the catheter. Itraconazole and amphotericin B were restarted, and the high fever and lumbar pain improved rapidly. The findings of S. apiospermum infection in this patient emphasizes the importance of being aware of this pathogen in patients with hematologic malignancy during the neutropenic phase.
