An analysis of 80 immunocompromised patients who were admitted to the intensive care unit (ICU) was made. It was 3 different groups: those treated chronically with more than 20 mg of prednisone or it's equivalent, patients with severe
neutropenia
(-500 PMN'S/mm3) and patients with AIDS. The reasons for admittance to the ICU were: pneumonia (51.2%), postoperative care (30%) extrapulmonary
sepsis
(8.7%) and other causes in 10%. Mortality was 62.5%. It was statistically higher in those that were admitted for pneumonia, developed respiratory failure, and required postoperative care after emergency surgery (80%, 89.5% and 70% respectively). Also in patients with multiple organic failure (3.2 +/- 1.6 vs 0.9 +/- 1.2 in survivors) and with higher APACHE II score (24 +/- 7 vs 15.4 +/- 6 in survivors). The mortality for acute respiratory failure, the principal organic failure observed, according to the primary diagnosis was: AIDS 100%, severe
neutropenia
85.7% and chronic use of steroids in 85.7% of the patients.

The efficacy and safety of the two antibiotic combinations, ceftazidime plus amikacin and ceftriaxone plus amikacin were compared in an open randomized trial. 100 episodes of
neutropenia
caused by malignant diseases and/or cytostatic drugs were evaluated in 66 males and 34 females with a mean age of 49.4 years. The types of infections treated were:
septicemia
38, fever of undetermined origin 26, pneumonia 13, ear, nose and throat infections 11 and others 12. 17 episodes were not evaluable (6 protocol violations, 6 doubtful infections and 5 non-bacterial infections). The overall results were comparable, with a 74% success rate for ceftazidime and a 70% rate for ceftriaxone (criteria of the European Organization for Research and Treatment of Cancer). In the patients with
septicemia
, the success rate was 64% in the ceftriaxone and 57% in the ceftazidime group. Eight patients died during the treatment, in 5 cases due to infectious complications. There were no differences between the two groups in respect of efficacy or toxicity.

The suppression of potentially pathogenic microorganisms using prophylactic antibacterial treatment could eventually protect the patient from infection. Oral absorbable and non-absorbable antibacterial agents have been used with variable results. In the present study, 47 patients with cancer and
neutropenia
received oral ofloxacin 200 mg twice daily prophylactically. All patients were previously treated with antineoplastic chemotherapy.
Septicemia
developed in ten patients (21%). The number of infections was higher in patients with a level of granulocytopenia under 0.5 x 10(9)/1. Infection was caused in almost all patients by gram-positive organisms. Prophylaxis with ofloxacin provided efficacious protection against gram-negative bacteria and was well tolerated.

Eighty-eight patients with haematological malignancies requiring Hickman catheters for intensive chemotherapy were randomized to receive either one single bolus intravenous injection of teicoplanin or no teicoplanin immediately before insertion of a double lumen Hickman catheter. There were lower incidences of catheter-related Gram-positive
sepsis
in patients receiving prophylactic teicoplanin. There were less exit site infections, tunnel infections and catheter-related Gram-positive septicaemia. The benefit of prophylactic teicoplanin was observed especially among patients who were already neutropenic at the time of catheterization. All Gram-positive organisms isolated from the infected skin sites or from blood cultures taken from the Hickman catheters were sensitive to teicoplanin. No adverse reaction was reported in any of the patients in the prophylactic group. Prophylactic teicoplanin therefore may be used routinely for patients requiring insertion of Hickman catheters for intensive chemotherapy to reduce the early incidence of catheter-related
sepsis
, especially during the associated period of
neutropenia
following chemotherapy.

The authors describe the clinical history of two adult patients with acute myeloid leukemia, who had severe
neutropenia
and thrombocytopenia. After chemotherapy in both patients had developed typhlitis with fatal outcome caused by
sepsis
. They discuss the etiopathogenesis and clinical features of necrotizing typhlitis as a complication of treated acute leukemia and point out the difficulty of the differential diagnosis and management.

Numerous abnormalities in neonatal host-defense mechanisms have been documented over the past decade. Profound disturbances in myeloid progenitor proliferation, bone marrow neutrophil storage pools, a tendency to peripheral
neutropenia
and significant in vitro abnormalities of mature neutrophil cell effector function all predispose the neonate to a high mortality rate during bacterial
sepsis
. The recent use of hematopoietic CSFs and other cytokines to enhance host defense mechanisms in the adult has suggested a role for this new form of immunotherapy in the newborn. Several studies over the past 2 years have indicated that a number of these cytokines may in fact enhance neonatal myeloid progenitor proliferation, modulate neonatal bone marrow neutrophil storage and proliferative pools, induce peripheral neutrophilia and protect against the high mortality rate associated with experimental bacterial
sepsis
to enhance neonatal host defense against overwhelming bacterial infection.

Monoclonal antibodies (MAb) directed against bacterial lipopolysaccharide (LPS) and tumor necrosis factor-alpha (TNF) provide partial protection in experimental models of septic shock. To determine if additional benefit accrues from a combination of anti-TNF and anti-LPS MAb in the treatment of septic shock, a neutropenic rat model was developed to study active infection with Pseudomonas aeruginosa 12.4.4. Animals were treated intravenously with an irrelevant MAb (group 1); anti-TNF MAb (group 2); MAb directed against P. aeruginosa 12.4.4 LPS (group 3); or a combination of anti-TNF and anti-LPS MAb (group 4). None of the control animals in group 1 survived the 7-d period of
neutropenia
(0/16). In contrast, the survival rate was 44% in group 2 (P less than 0.02); 37% in group 3 (P less than 0.05); and 75% in group 4 (P less than 0.0002). The combination of monoclonal antibodies provided greater protection than either MAb given alone (P less than 0.05). Serum TNF levels during infection were significantly greater in groups 1 and 3 (20.1 +/- 3.3 U, mean +/- SE) than in groups 2 and 4 (0.9 +/- 0.8 U, P less than 0.0001). These results indicate that a combination of monoclonal antibodies to LPS and TNF have additive benefit in experimental Pseudomonas aeruginosa
sepsis
. This immunotherapeutic approach may be of potential utility in the management of serious, gram-negative bacterial infection in neutropenic patients.

This study was designed to test the hypothesis that administration of immune globulin to human neonates with early-onset bacterial
sepsis
would (1) facilitate neutrophil egress from the marrow, (2) improve serum opsonic capacity, and (3) facilitate recovery from the infectious illness. Twenty-two newborn infants with clinical signs of early-onset
sepsis
were given an intravenous infusion of either 750 mg of immune globulin (IVIG) per kilogram of body weight or the same volume of a vehicle control (albumin). All 22 infants survived, but significant hematologic, immunologic, and respiratory differences were observed after the IVIG and not after the control infusion. Eleven of the patients had
neutropenia
; 24 hours after the infusions, the
neutropenia
had resolved in all six IVIG recipients but persisted in all five control recipients (p less than 0.001). Ten patients had I/T neutrophil ratios (a measure of immature neutrophils to total neutrophils on the leukocyte differential count) of less than 0.2. One hour after completion of the infusions, all five IVIG recipients had elevated I/T ratios (mean +/- SEM:0.10 +/- 0.05 before vs 0.43 +/- 0.03 after infusion; p less than 0.001), suggesting a prompt release of neutrophils from the marrow neutrophil storage pool into the circulation; no increase in the I/T ratio was observed in the control recipients. Six hours after the IVIG infusions, the ratio of arterial oxygen tension to fraction of inspired oxygen increased; no increase was observed after control infusions. Serum concentrations of IgG, IgG1, IgG2, IgG3, IgG4, and total hemolytic complement and the capacity of serum to support opsonophagocytosis of type II and type III group B streptococci increased markedly in the IVIG recipients but not in the control subjects. We conclude that administration of 750 mg IVIG per kilogram to neonates with clinical signs of early-onset
sepsis
was associated with immunologic, hematologic, and physiologic improvement.

Myelosuppression in patients with cancer is usually the result of tumor invasion of the bone marrow, cytotoxic chemotherapy, or radiation therapy, all of which suppress bone marrow function. Anemia, thrombocytopenia, and
neutropenia
are the three most clinically significant complications that result from bone marrow depression. Although anemia and thrombocytopenia can produce serious clinical problems, blood-component transfusions--despite having inherent problems of their own--usually are successful in correcting or minimizing these complications. Although
neutropenia
is manageable in most situations, it remains a serious problem that, at its worst, can progress to life-threatening
septicemia
. The longer neutrophil counts remain low, the more susceptible patients become to infection by endogenous and exogenous microbial flora. Accordingly, the oncology nurse increases the frequency of patient assessment and monitoring for infection. Control measures are introduced to minimize environmental contaminants. These measures attempt to reduce the incidence of opportunistic infections that frequently occur in patients with severe or prolonged
neutropenia
and for which antimicrobial therapy is indicated. Implementing specific infection-control interventions and thoroughly educating the patient and his/her family help to limit the clinical problems associated with myelosuppression for most patients.

A hyperdynamic
sepsis
model was set up in seven adult baboons to evaluate neutrophil-activating peptide-1/interleukin (IL)-8 (NAP-1/IL-8), IL-1 beta, IL-6, tumor necrosis factor-alpha (TNF alpha), and IFN-gamma in plasma. By continuous intravenous administration of 10(10) cfu/kg live Escherichia coli over 8 h with additional infusion therapy (less than or equal to 50 ml/kg/h), endotoxin plasma levels of 2.7-22.3 ng/ml were observed. In plasma the kinetics of NAP-1/IL-8 and IL-6 were similar to those of IL-1 at the end of the experiment (8 h) (peak median values, 34, 4197, and 230 ng/ml, respectively). Differences were greatest for IL-6. Monocyte activation during
sepsis
was confirmed by elevated plasma neopterin levels (91-139 mumol/mmol of creatine). Granulocyte activation was evident from both incipient
neutropenia
and the massive release of neutrophil elastase into the plasma as measured by a new immunoassay (peak level, 374 ng/ml). Thus, in primate bacteremia, early TNF release is followed by a concomitant increase of NAP-1/IL-8 with plasma kinetics similar to those of IL-6 and IL-1 and accompanied by massive activation of neutrophils.
