Abstract
Human cyclic neutropenia occurs in children and adults. Adult-onset cyclic neutropenia is an acquired disease characterized by increased numbers of large granular lymphocytes (LGL), in contrast to childhood-onset cyclic neutropenia in which LGL counts are normal. We investigated the clonality of lymphocytes in these two groups of patients by assessing the rearrangement status of the T cell receptor beta chain gene. Patients with adult-onset cyclic neutropenia showed clonal rearrangement of the T beta gene whereas the children did not. Since LGL are known to have multiple regulatory effects on normal hematopoiesis, the finding of a clonal proliferation of this lymphocyte population implicates these cells in the pathogenesis of cyclic neutropenia.

Abstract
Cyclic hematopoiesis (CH), also called cyclic neutropenia, is an inherited disorder known to occur in both humans and gray collie dogs. Previous reports have provided ample evidence to suggest that lymphocyte activity and regulatory mechanisms may be abnormal in CH. The present study examined the lymphocyte populations of several lymphoid compartments of gray collie dogs. The percentage of B lymphocytes in the lymph nodes of CH dogs was significantly increased whereas that of null lymphocytes was decreased. The percentage of T lymphocytes did not differ between CH and normal dogs, however, the proportions of T lymphocyte subpopulations were significantly different. The levels of T lymphocytes expressing IgGFc receptors (T gamma) in the thymus, lymph nodes, and peripheral blood were significantly increased; whereas the levels of T lymphocytes expressing IgMFc receptors (T mu) were significantly decreased. The percentage and absolute numbers of T gamma and T mu lymphocytes cycled in CH dogs. The percentage and absolute numbers of neutrophils were greatest when that of T gamma lymphocytes was reduced. The cycles of monocytes and T gamma lymphocytes occurred in close association and a linear relationship between the levels of these cells was observed both in terms of percentage (r = 0.62; P less than 0.01) and absolute number (r = 0.67; P less than 0.05). The percentage of T gamma and T mu lymphocytes were inversely correlated (r = -0.68; P less than 0.01).

Abstract
A 20-year-old female from the Philippines developed anemia and granulocytopenia. With androgen therapy, her anemia improved but she continued to show a pattern of fluctuating neutropenia consistent with human cyclic neutropenia: Blood neutrophil oscillation was regular with a periodicity of 21 days. She developed recurrent pharyngitis and apthous stomatitis but there was no cycling of other blood elements. Bone marrow aspiration and biopsy showed normal developing myeloid cells, a clonal chromosomal abnormality, and myelofibrosis. During the fourth documented cycle, blasts appeared and complete lymphoblastic transformation ensued. Blast cells were CALLA positive, Ia positive, and contained intranuclear TdT; they were negative for E, EAC, and EA rosettes. She was treated for non-T, non-B CALLA-positive ALL and within 6 weeks was in a remission without evidence of cycling neutrophil counts. This young woman's case suggests that cyclic neutropenia may represent a previously unrecognized premalignant state associated with acute lymphoblastic leukemia.

Abstract
A patient is described who has had a marked eosinophilia of unknown cause for 9 years in association with episodic facial swelling. Weekly blood counts for 8 months showed cyclical variations in eosinophils, neutrophils and monocytes (mean cycle length 35 d). Marrow culture studies showed fluctuation in the incidence of granulocyte-macrophage colonies (GM-CFC), and the proportion of eosinophil colonies was higher than the values reported for normals. The blood lymphocyte T4/T8 ratio was reversed, due to an increase of T8+ cells. It is suggested that this condition is a rare form of periodic haemopoiesis.

Abstract
Cyclic haematopoiesis (CH) is an inherited disorder which occurs in both humans and Grey Collie dogs. The disease is characterized by fluctuations in the numbers of peripheral blood leucocytes, reticulocytes and platelets at regular intervals and is associated with a variety of clinical signs. The most prominent cycle observed is that of neutrophils. The 12-day neutropenic cycle includes a period of relatively normal neutrophil counts, a period of neutropenia and generally a period in which neutrophil counts greatly exceed the normal range. In this study the daily serum haemolytic complement activity (classical pathway CH50) of CH and normal Collie dogs was assayed. The serum CH50 of normal Collie dogs was relatively stable throughout the test period. In contrast, the serum CH50 of CH dogs fluctuated extensively and the mean serum CH50 of CH dogs during the neutropenic cycle greatly exceeded that of normal Collie dogs over the same test period. A close temporal relationship between the stage of the CH neutropenic cycle and the serum CH50 was observed. The mean serum CH50 during neutropenia was not significantly different from that observed when neutrophil counts were within normal range, both values being significantly higher than that of normal dogs. However, the mean serum CH50 during the period of neutrophil rebound was significantly (P less than 0.01) higher than that during the period of neutropenia or normal neutrophil counts. These data suggest that alterations in the production of complement components or regulatory proteins occur at regular intervals in CH dogs.

Abstract
Neutropenia is a transient or chronic blood disorder characterized by a decrease in the number of circulating polymorphonuclear leukocytes (PMNs). Neutrophils are a major cellular defense against infection, and depletion of these cells is potentially fatal. Stomatitis and gingivitis frequently are seen in patients with neutropenia. Therefore, the diagnosis of severe oral pathoses of obscure origin must include a differential white blood cell count. The importance of the dentist's role is dramatically illustrated in the rare case reported here, since the oral condition was the reason for this patient's definitive blood work-up. The report illustrates the importance of the laboratory assessment in dental patients with unusual periodontal destruction or other inexplicable oral changes.

Abstract
The hematopoietic and the immune systems in all their components are characterized by a multifrequency time structure with prominent rhythms in cell proliferation and cell function in the circadian, infradian, and rhythms in cell proliferation and cell function in the circadian, infradian, and circannual frequency ranges. The circulating formed elements in the peripheral blood show highly reproducible circadian rhythms. The timing and the extent of these rhythms were established in a clinically healthy human population and are shown as chronograms, cosinor summaries and, for some high-amplitude rhythms, as time-qualified reference ranges (chronodesms). Not only the number but also the reactivity of circulating blood cells varies predictably as a function of time as shown for the circadian rhythm in responsiveness of human and murine lymphocytes in vitro to lectin mitogens (phytohemagglutinin and pokeweed mitogen). Some circadian rhythms of hematologic functions appear to be innate and are presumably genetically determined but are modulated and adjusted in their timing by environmental factors, so-called synchronizers. Phase alterations in the circadian rhythms of hematologic parameters of human subjects and of mice by manipulation of the activity-rest or light-dark schedule and/or of the time of food uptake are presented. Characteristically these functions do not change their timing immediately after a shift in synchronizer phase but adapt over several and in some instances over many transient cycles. The circadian rhythm of cell proliferation in the mammalian bone marrow and lymphoid system as shown in mice in vivo and in vitro may lend itself to timed treatment with cell-cycle-specific and nonspecific agents in an attempt to maximize the desired and to minimize the undesired treatment effects upon the marrow. Differences in response, and susceptibility of cells and tissues at different stages of their circadian and circaseptan (about 7-day) rhythms and presumably of cyclic variations in other frequencies are expected to lead to the development of a chronopharmacology of the hematopoietic and immune system. Infradian rhythms of several frequencies have been described for numerous hematologic and immune functions. Some of these, i.e., in the circaseptan frequency range, seem to be of importance for humoral and for cell mediated immune functions including allograft rejection. Infradian rhythms with periods of 19 to 22 days seem to occur in some hematologic functions and are very prominent in cyclic neutropenia and (with shorter periods) in its animal model, the grey collie syndrome.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A 16-month-old male patient with cyclic neutropenia was found to have cyclic fluctuations of monocytes, lymphocytes, platelets, and eosinophils in the peripheral blood. Changes in lymphocyte counts were not obviously related to B, T, or natural killer cells. All classes of immunoglobulins were elevated throughout the cycle. Studies of the marrow morphology revealed remarkable cyclic oscillations of lymphoid as well as myeloid lineage cells. Granulocyte-macrophage progenitors (CFU-c) cycled and were virtually absent 1 wk prior to the neutropenic nadir. The cyclic changes in marrow lymphoid cell numbers were primarily due to changes in numbers of surface immunoglobulin negative (sIg-), cytoplasmic Ig+ (cIg+) pre-B cells. Pre-B cell numbers cycled from normal to extraordinarily elevated values with the same periodicity but reciprocal to the neutrophil cycle. We propose that the primary defect in cyclic neutropenia may either be a periodic failure of an early myeloid differentiation factor or a blunted response of early myeloid precursors to a common hemopoietic growth factor. This may lead to periodic fluctuations in the production or delivery of growth factors (or factor) that influence early stages of differentiation of other hemopoietic cells, including pre-B cells. The essential periodic deficiency is consequently reflected in deficient production of CFU-c accompanied by excessive production or accumulation of pre-B cells (and probably other hemopoietic precursors) in the marrow.

Abstract
A patient with periodic neutropenia exhibited simultaneous monocytopenia, and epinephrine infusion revealed no monocytes in the marginating pool during neutropenia. Lymphocytes, eosinophils, and platelets also fluctuated periodically, but serial bone marrow studies and epinephrine infusion data indicate these fluctuations could have represented epiphenomena rather than a more global form of periodic hematopoiesis. Bone marrow descriptions of most cases of periodic neutropenia have indicated a "maturation arrest" at the promyelocyte or myelocyte stage prior to development of neutropenia; peripheral blood monocytes are usually normal or fluctuate out of phase with neutrophils. In this present case, "maturation arrest" occurred at the myeloblast stage, and neutrophils and monocytes cycled together. Morphologically normal eosinophilopoiesis with a mean eosinophil to erythroid ratio in the marrow of 0.27 +/- 0.10 (SD) persisted despite a sustained disappearance of promyelocytes.

Abstract
To investigate the mechanisms of cyclic neutropenia, we studied the capacity of a patient's T lymphocytes (TLp) to interact with monocyte-macrophages from her normal HLA-identical sibling (MOb) in the elaboration of colony-stimulating activity (CSA). TLp obtained at the time of decreasing neutrophil counts, increased CSA elaboration (p less than 0.056) when incubated at a 1:1 ratio with MOb. Increasing the TLp to MOb ratios to 3:1 or 5:1 progressively decreased CSA. Also, lithium carbonate, which ordinarily prevents concanavalin A activation of suppressor TL, failed to do so, suggesting that preactivated suppressor TL were present in the patient while neutrophil levels were falling. In similar experiments performed while neutrophil levels were rising these activated suppressor TL were absent. These data suggest that some patients with cyclic neutropenia may have a cyclic increase in suppressor TL activity. As predicted by our in vitro experiments, lithium carbonate administration did not abrogate the first neutropenic cycle, but it did mitigate subsequent cycles.

Abstract
A 62-year-old woman had recurrent fluctuations of neutrophil, monocyte, reticulocyte and platelet counts with a cycling time of 38.5 d. Periodic fluctuations of granulo-, erythro- and megakaryopoiesis were also demonstrated in her bone-marrow. Oxymetholone reduced the magnitude of the profound cyclic fluctuations in all these cell lines. During treatment a reduced number of in vitro CFU-C of the progenitor myeloid series from the bone marrow was observed. Using the patient leucocytes as feeders for normal control marrow cells, indication was found for a fluctuation in colony stimulating activity in vitro, rising above normal at the nadir of the WBC.

Abstract
Lithium carbonate has been shown to increase granulocyte production. We studied the effect of lithium on murine hematopoiesis in a liquid culture system providing for the prolonged growth of stem cells and their progeny. After one week of incubation, lithium, at a supernatant concentration of 1 mmol per liter, increased murine pluripotent stem cells (CFU-S, or colony-forming units in spleen) to 232 per cent of control values (P less than 0.001), granulocyte-monocyte progenitor cells (CFU-C, or colony-forming units in culture) to 218 per cent of control values (P less than 0.0001), granulocytes to 125 per cent of control values (P less than 0.01), and megakaryocytes to 246 per cent of control values (P less than 0.001). These increases were associated with transient elevations in colony-stimulatory activity. Prolonged exposure to lithium (three to 12 weeks) was associated with a dose-dependent progressive depletion of stem cells and their progeny. Lithium enhancement of granulopoiesis may be explained by primary stimulation of the pluripotent stem cell. Prolonged proliferative stress induced by lithium when the stem-cell reserve is limited may be associated with diminished replicative potential of the stem cells and rapid depletion of cells.

Abstract
The concentration of granulocytic progenitor cells in the bone marrow of 2 patients with cyclic neutropenia was assessed at intervals during the cycle. Syncroneous oscillations were observed for cells forming neutrophilic and megakaryocytic colonies in diffusion chambers in vivo (CFU-D), suggesting a close relationship between the two cell types. However, an almost reverse relationship was observed between CFU-D and cells forming colonies in agar culture in vitro (CFU-C), which cycled out of phase with CFU-D. This supports the concept that CFU-D and CFU-C denote different cell types.

Abstract
In addition to standard peripheral blood cell counts, sequential studies have been made of changes in the T-lymphocyte population and in the serum titres of the presumptive humoral regulators of haematopoiesis, Colony Stimulating Activity (CSA) and Erythroid Stimulating Activity (ESA), in a young woman with cyclic neutropenia (CN). In addition, serum immunoglobulins, C3 and total complement levels and serum protein concentrations were determined on several occasions during the study. Similar tests were done concomitantly on a haematologically normal, age and sex-matched control. Cell counts on peripheral blood from the subject with CN demonstrated a clearly defined periodicity in neutrophil and monocyte concentrations and equivocal fluctuations in reticulocyte numbers. There was no evidence of periodicity in the lymphocyte concentrations and the T-lymphocyte population appeared functionally normal. Spontaneous incorporation of tritiated thymidine into peripheral blood cells showed a highly significant correlation with the monocyte count, suggesting that these cells were responsible for the radioisotope uptake. CSA titres were elevated on all occasions tested and showed no evidence of periodicity. ESA showed some evidence of cycling with elevated levels being observed during the periods of neutropenia. Serum complement levels were within the normal range but all classes of immunoglobulins were elevated and albumin levels were depressed.

Abstract
A 70-year-old woman with cyclic neutropenia was treated with 16 mg of etiocholanolone and 25 mg of prednisolone intramuscularly every other day. During 14 weeks' treatment amplitude of cyclic fluctuations in neutrophil counts gradually decreased, but pretreatment cycles returned promptly after treatment was stopped. Prednisolone alone every other day (25 mg) reproduced this result, and by 23 weeks, neutrophil counts became stable at about 1500 per cubic millimeter. tcycling of monocytes, platelets and reticulocytes was also eliminated, as were symptoms that had accompanied neutropenic periods. In addition, bone-marrow neutrophil precursors and neutrophil marrow reserves were stabilized. The patient was subsequently maintained satisfactorily with oral prednisolone, 20 mg every other day. These studies demonstrate that the discontinuous myeloid maturation that occurs in cyclic neutropenia can be corrected with prednisolone every other day.

Abstract
Cell kinetics have been studied at several periods in a patient with typical cyclic neutropenia. Peripheral blood granulocyte labelling showed an increased destruction in the preleucopenic phase. Bone marrow colony-forming cells and blood leucocyte colony forming activity were normal or above the normal range. The major abnormalities were found in sequential studies of bone marrow proliferation measured by "in vitro" 3H-thymidine flash labelling. A fall in the labelling index of promyelocytes was observed in the second part of the cycle. Incubation of normal human bone marrow cells with patient's granulocytes showed a marked decrease in 3H-thymidine incorporation, compared with incubation with the same number of normal granulocytes. Human cyclic neutropenia seems to be due to a factor secreted by abnormal polymorphonuclears inhibiting myeloid proliferation.

Abstract
The treatment of a 12-year-old girl with a lifelone history of recurrent infections and aphthous stomatitis is reported. A profound neutropenis, first noted at the age of 2 years, occurring at least every month was observed together with multiple mouth ulcers a sore throat and swelling of the jugular glands. Levamisole, originally described as an anthelmintic, has a beneficial effect on the symptoms of recurrent aphthous stomatitis. After levamisole treatment aphthous stomatitis was milder and in the 1-year follow-up period the patient was asymptomatic several times during a phase of obvious neutrophil depression. The child no longer complained of a sore throat with swelling of the jugular glands and the recurrent staphylococcal infections of the skin disappeared. After therapy a marked increase in monocytes at the moment of neutropenia was observed.

Abstract
Cellular and humoral factors involved in the regulation of granulopoiesis were evaluated in two patients with cyclic neutropenia by utilizing the agar-gel marrow culture technique to serially study marrow granulocytic colony-forming capacity (CFC) and the urinary output of colony-stimulating factor (CSF). CSF output varied inversely with peripheral neutrophil counts and directly with monocyte counts and evidence for infection (endotoxemia and/or staphylococcal abscesses). Following autologous infusion of one patient's plasma obtained during a period of neutropenia, increased urinary excretion of CSF occurred concomitant with increments in both marrow CFC and the proportion of granulocytic progenitor cells in DNA synthesis. Neutrophil periodicity was not altered by the administration of the neutropenic plasma. These findings are consistent with the hypothesis that cyclic neutropenia is caused by a quantitatively decreased entry of stem cells or granulocytic progenitor cells into granulopoiesis.

In vitro studies have been done on haematopoietic cells from a patient with cyclic neutropenia characterized by severe depression of blood neutrophil levels every 21 days. Serial blood counts reveal periodic fluctuations in neutrophils, monocytes and reticulocytes. Agar culture of marrow cells shows normal concentration of colony forming cells. The percentage of colony forming cells in S phase is highly increased during profound neutropenia and normal during the recovery phase relating the granulocyte production to the peripheral neutrophil level. Studies of ingestion rate, bactericidal activity, lactate production and glucose oxidation during phagocytosis in isolated granulocytes show normal results. Also the ingestion rate in isolated monocytes is normal. Serial karyotype analyses of marrow cells during the neutrophil cycle display a normal pattern. Serum myeloperoxidase levels vary inversely with the peripheral neutrophil count indicating increased granulopoietic activity during profound neutropenia, which might be associated with non effective granulopoiesis during profound neutropenia, leading to a lack of granulocyte reserves in the marrow.

Abstract
The prednisone test revealed normal bone marrow reserve of neutrophils (BMR) in subjects with innocent neutropenias e.g. neutropenias not associated with any other disturbances in haemopoiesis or with increased incidence of infections, assumed to be an individual anomaly of the subject. On the other hand, diminution or absence of MBR in chronic hypoplastic neutropenias, transient post-chemotherapeutic neutropenias and neutropenias with increased destruction of neutrophils were observed. The magnitude of that diminution was not dependent of the cause of neutropenia. It is suggested, that the prednisone test (and probably tests with other BMR mobilizing agents) may serve as screening tests for exclusion (or confirmation) of relative granulopoietic insufficiency as the cause of neutropenia. Only after confirmation of reduced BMR another explanations of neutropenia should be sought using other method as muramidase level, adrenaline test or granulocyte kinetics with DF32P, 3HDFP, or 51Cr.
