Chronic neutrophilic leukemia is a rare, infrequently recognized, myeloproliferative disorder. It usually manifests as a leukemoid reaction, with mostly mature granulocytes in the peripheral blood, with rare to occasional immature forms, and sometimes with normoblasts. The clinical manifestations also include hepatosplenomegaly, elevated leukocytic alkaline phosphatase, elevated serum vitamin B12 and serum vitamin B12 binder ("R" fraction), and elevated serum uric acid. Distinction from a leukemegaly, the absence of sepsis, usually normal erythrocytic sedimentation, and the absence of fever. Leukemoid reactions may be associated with elevated serum vitamin B12 and uric acid, but the levels are usually lower than those found in chronic neutrophilic leukemia. Many patients have gouty symptoms, especially after treatment with Busulfan, and many have an unexplained hemorrhagic tendency, making major operations a risk. The authors add two cases to the 11 previously described.

Clostridium sordellii is a gram-positive, anaerobic bacillus that has rarely been implicated as a human pathogen. It produces several exotoxins, which contribute to the progressive edema and refractory shock frequently seen with human infection. There have been eight prior reports of bacteremic C. sordellii infection and seven prior reports of nonbacteremic infections not due to myonecrosis of skeletal muscle. Mortality was 50% in the bacteremic group and 71% in the nonbacteremic group. Mortality correlated with both shock and leukemoid reaction at presentation. We present a case of C. sordellii sepsis in an asplenic patient with sickle beta thalassemia and inflammatory bowel disease, and we review the literature.

Paroxysmal nocturnal hemoglobinuria (PNH) has been observed to evolve into myelofibrosis and acute myeloid leukemia. Myeloblastic leukemoid reaction has not been described in PNH. We described a patient with PNH with myelodysplasia and septicemia. The marrow aspirates showed a picture of myeloblastosis which subsided when sepsis was controlled. The myeloblastic leukemoid reaction in our patient related to overwhelming sepsis, splenectomy and overt hemolysis.

We report a new case of the unusual myeloproliferative syndrome chronic neutrophilic leukemia (CNL) that met all the criteria generally required for the diagnosis of this entity. The patient presented abnormalities in platelet function not previously reported that may explain the bleeding tendency observed in these patients. The study of neutrophil function suggested also defective mobility and intracellular bactericidal activity. The chromosomal study revealed original abnormalities consisting of multiple chromosomal ruptures and figures. The disease was controlled with busulfan. After 20 months, the patient died of sepsis. An autopsy was performed confirming the diagnosis and ruling out the existence of a cause of a leukemoid reaction, such as cancer or granulomatous disease.

The prevalence, presentation, and outcome of bacteremia due to Shigella and other gram-negative bacteria were determined by review of records of 2,018 inpatients with shigellosis who had their blood cultured in a Bangladeshi hospital in 1976-1983. Shigella bacteremia occurred in 82 (4.1%) patients; other bacteremia occurred in 102 (5.1%) patients. Patients with shigella sepsis more frequently (P less than .02) manifested severe dehydration, abdominal tenderness or ileus, agitation or lethargy, and leukocytosis than did nonbacteremic controls; they developed more frequently (P less than .05) renal failure (26%), leukemoid reaction (22%), thrombocytopenia (20%), and hemolytic-uremic syndrome (6%). The prevalence of all bacteremia was highest in the first year of life. Protein-energy malnutrition was a strong risk factor for shigella sepsis (P less than .01). The fatality rate in shigella bacteremia (21%) was higher (P less than .005) than in nonbacteremic shigellosis (10%) but lower (P less than .001) than in other bacteremia (51%). At highest risk of death from shigella bacteremia (P less than .01) were patients less than one year old, non-breast-fed, malnourished, and afebrile.

A 52 yr old Caucasian female (F. E.) had hemolytic anemia, a leukemoid reaction, and fatal sepsis due to Escherichia coli. Her leukocytes ingested bacteria normally but did not kill catalase positive Staphylococcus aureus, Escherichia coli, and Serratia marcescens. An H(2)O(2)-producing bacterium, Streptococcus faecalis, was killed normally. Granule myeloperoxidase, acid and alkaline phosphatase, and beta glucuronidase activities were normal, and these enzymes shifted normally to the phagocyte vacuole (light and electron microscopy). Intravacuolar reduction of nitroblue tetrazolium did not occur. Moreover, only minimal quantities of H(2)O(2) were generated, and the hexose monophosphate shunt (HMPS) was not stimulated during phagocytosis. These observations suggested the diagnosis of chronic granulomatous disease. However, in contrast to control and chronic granulomatous disease leukocytes, glucose-6-phosphate dehydrogenase activity was completely absent in F. E. leukocytes whereas NADH oxidase and NADPH oxidase activities were both normal. Unlike chronic granulomatous disease, methylene blue did not stimulate the hexose monophosphate shunt in F. E. cells. Thus, F. E. and chronic granulomatous disease leukocytes appear to share certain metabolic and bactericidal defects, but the metabolic basis of the abnormality differs. Chronic granulomatous disease cells lack oxidase activity which produces H(2)O(2); F. E. cells had normal levels of oxidase activity but failed to produce NADPH due to complete glucose-6-phosphate dehydrogenase deficiency. These data indicate that a complete absence of leukocyte glucose-6-phosphate dehydrogenase with defective hexose monophosphate shunt activity is associated with low H(2)O(2) production and inadequate bactericidal activity, and further suggest an important role for NADPH in the production of H(2)O(2) in human granulocytes.

A retrospective study was conducted to analyze the surgical aspects of the splenectomy in chronic myelogenous leukemia. Twenty patients, Philadelphia chromosome-positive, were initially treated with busulfan until remission was reached. Elective splenectomy was then performed and chromosomal studies repeated at four- and six-month intervals yielding the indication for cyclic intensive chemotherapy. There ws no mortality, one episode of gram-negative sepsis with shock, and five instances of minimal complications. The spleen weights averaged 265 g, ranging from 60 to 800 g. All patients had normal coagulation profiles at the time of surgery, but four of them developed a postoperative thrombocytosis without related complications. A specific correlation was noted between postoperative thrombocytosis and splenomegaly (average weight 570 g). Eleven patients showed a high postoperative leukemoid reaction (average 40,500 cells/cu mm). The interval between diagnosis and splenectomy was shorter (average 7.5 months) in this group than for the patients who had a lower granulocytosis (average 19.5 months).

Alterations in peripheral blood neutrophil function are known to occur in patients with colitis and may have a role in precipitating nonspecific tissue injury. It is not known whether neutrophil function is altered in patients with Shigella dysenteriae type 1 infection, during which there is extensive colitis and which may be associated with life-threatening complications in young children. Three aspects of peripheral blood neutrophil function, polarization, attachment to yeast particles, and locomotion, were therefore studied in 111 children with S. dysenteriae type 1 infection and 57 children without any infection. All children were aged 12 to 60 months. Of the children with S. dysenteriae type 1 infection, 42 had leukemoid reaction, hemolytic-uremic syndrome, or septicemia (complicated shigellosis), while the others did not (uncomplicated shigellosis). Polarization and locomotion in the absence of chemoattractants and in response to N-formylmethionyl-leucylphenylalanine (FMLP) and the lipopolysaccharide (LPS) of S. dysenteriae type 1 were determined. Attachment to unopsonized and opsonized yeast particles was also determined. Children with shigellosis (uncomplicated or complicated) had more polarized neutrophils with and without chemoattractants than uninfected children (P < 0.05). Children with complicated shigellosis had more polarized neutrophils with FMLP at 10(-7) and 10(-6) M (P < 0.05) and with LPS than children with uncomplicated shigellosis (P < 0.05). At 3 to 5 days after enrollment, the numbers of polarized neutrophils with 10(-8), 10(-6), and 10(-5) M FMLP declined in children with uncomplicated shigellosis but not in those with complicated shigellosis. Attachment to yeast particles was similar in all three groups of children. Locomotion was inhibited by LPS in children with shigellosis (P < 0.05), whether it was uncomplicated or complicated, compared with locomotion in uninfected children. Finally, neutrophil polarization in uninfected children was negatively influenced by nutritional status. Thus, poorly nourished uninfected children had more polarized neutrophils with FMLP at 10(-9) M (P < = 0.02) and 10(-5) M (P = 0.043) than their better-nourished counterparts. In summary, altered neutrophil responses are associated with both uncomplicated and complicated shigellosis.

There have been no previous concrete reports of leukemoid reactions associated with squamous cell carcinoma originating in cutaneous tissue. Here we report a case of epidermal squamous cell carcinoma of the sacral region and an associated leukemoid reaction. The tumor invaded deeply and destroyed both the sacrum and coccyx. The white blood cell count was greater than 20,000/mm3. After resection of the tumor, white blood cells transiently decreased, but did not fall under 10,000/mm3. Post-operative infection by methicillin-resistant Staphylococcus aureus and Bacteroides caccae caused sepsis and further elevation of the leukocytes to greater than 50,000/mm3. The leukemoid reaction in the case appeared to have been caused initially by direct invasion of bone by epidermal squamous cell carcinoma and later by severe infection.

We report 81 of 107 cases of hemolytic uremic syndrome (HUS), admitted between July 1994 and February 1996, following an outbreak of Shigella dysenteriae type 1 dysentery in Kwazulu/Natal. All patients, excluding 1, were black with a mean age of 38 months (range 1-121); 50 (61.7%) were males. The mean duration of dysentery was 11.3 days (range 1-41) and HUS 15 days (range 1-91). Most patients had acute oliguric renal failure (90.1%), 42 (51.6%) required peritoneal dialysis. Complications included encephalopathy 30 (37.0%), convulsions 12 (14.8%) and hemiplegia 2 (2.3%), gastrointestinal perforation 8 (9.9%), protein losing enteropathy 26 (32.1%), toxic megacolon 4 (4.9%), rectal prolapse 5 (6.2%), hepatitis 11 (13.6%), myocarditis 5 (6.2%), congestive cardiac failure 3 (3.7%), cardiomyopathy 3 (3.7%), infective endocarditis 1 (1.2%), septicemia 15 (18.5%), disseminated intravascular coagulation 17 (21%). Leukemoid reactions were found in 74 (91.3%) patients, hyponatremia in 56 (69.1%), and hypoalbuminemia in 67 (82.7%). Stool culture for Shigella dysenteriae type I was positive in only 7 (8.6%) patients; Shiga toxin assays were not performed. Outcome was as follows: recovery 32 (39.5%), impaired renal function 8 (9.9%), chronic renal failure 26 (32.1%), end-stage renal disease 1 (1.2%), and death 14 (17.3%) patients.
