A child, who had undergone ventriculoperitoneal shunting, presented with repeated episodes of pneumonia and expectoration of CSF. Chest x-ray demonstrated the presence of the shunt catheter in the base of the left lung. In the present case the distal end of the catheter perforated the diaphragm, entering the thoracic cavity through the pleura and penetrating the pulmonary parenchyma. CSF then flowed freely into the alveoli and bronchi and became expectorated during repeated bouts of coughing associated with pneumonia. This respiratory complication disappeared after the removal of the catheter. We theorize that the penetration of the catheter into the thoracic cavity was secondary to its displacement from the iliac fossa to the left infradiaphragmatic space between the spleen and the diaphragm where the intra-abdominal pressure is lowest. The respiratory movements and the hypertension inside the abdomen created a constant friction of the catheter against the diaphragm which was finally perforated, permitting the passage of the peritoneal end of the shunting device into the thoracic cavity and secondary penetration of the lung.

Fifteen cases of Haemophilus influenzae (HI) meningitis in adults occurring of Cleveland during the last 11 years are presented. The majority of patients had factors predisposing to infection such as otitis, pneumonia, diabetes or alcoholism. In addition, 7 of the 15 patients developed meningitis at various intervals following head trauma and neurosurgery, and 3 patients required dural repairs for CSF rhinorrhea. The diagnosis of meningitis may be difficult to establish resulting in delay in appropriate therapy in some cases. Nuchal rigidity was absent frequently; CSF lymphocytosis can be seen initially. The CSF Gram stain may be negative or the pleomorphic nature of the organism on Gram-stain may make distinction from other gram-negative organisms difficult. The majority of patients had meningitis due to non-Type B HI in contrast to previous reports of this illness in children and adults. One of our patients had beta-lactamase producing HI isolated from CSF. We believe that chloramphenicol should be included in the initial empiric therapy for adults with meningitis and gram-negative coccobacillary rods on Gram-stain or negative CSF Gram-stains.

Three children suffered from mumps meningoencephalitis and pneumonia. The clinical course was uneventful. After 2 weeks antibiotic therapy for pneumonia a repeat lumbar puncture showed a massive increase of CSF protein levels. This phenomenon was transitory. It is explained by an obstruction in CSF pathway in the course of mumps meningoencephalitis.

Cefoxitin (CFX) was evaluated for its safety and efficacy in children. Fifteen patients were treated with 73-125 mg/kg per day of CFX by intravenous administrations. The diagnosis of the patients were acute pharyngitis (4), pneumonia (2), pertussis and pneumonia (1), urinary tract infection (3); and the remaining 5 patients were esteemed to have nonbacterial infections. All the 10 patients of bacterial infections were cured after the CFX therapy. The pathogens recovered were Streptococcus pyogenes (1), Streptococcus pneumoniae (3), Haemophilus influenzae (2), Escherichia coli (2), enteropathogenic Escherichia coli (1), and Klebsiella pneumoniae (1). All the strains isolated were susceptible to CFX, but the 2 isolates of Haemophilus influenzae had relatively high MIC values (12.5 mcg/ml). Diarrhea (3 cases) and transient neutropenia (1 case) were found to be associated with the CFX therapy. However, no severe adverse reactions were encountered. Half-life of the serum level was short (24.1 minutes) and excretion into the urine was rapid. CSF concentration obtained 30 minutes after an intravenous injection of 50 mg/kg of CFX in 1 case with inflamed meninges was considerably high (8.3 mcg/ml). CFX appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections.

A 54-year-old man was admitted with pneumonia and pancytopenia (WBC 400/microliters, RBC 297 x 10(4)/microliters, Hb 10.1g/dl, Plt 5.6 x 10(4)/microliter). Bone marrow aspiration revealed a proliferation of leukemic cells (61.6%) and led the diagnosis of AML (M2). Although no antileukemic agent had been administered previously, the combination therapy of antimicrobials and rhG-CSF for the infection not only improved pneumonia, but also induced a complete remission of AML. The short-term remission was followed by the first relapse of AML, in spite of the continuous administration of rhG-CSF. The abnormal karyotype (47, XY, +8) shown in the chromosomal analysis of the bone marrow cells at admission remained on the first remission. The second complete remission was induced by combination chemotherapy (BHAC-DMP), and the chromosomal analysis at this time showed a normal karyotype. These findings suggested that the first remission of AML in this case was caused mainly by the maturation induction effect of rhG-CSF on the leukemic cells, however, the possibility of the spontaneous remission in this case also remained.

A 48-year-old man developed refractory anemia with excess of blasts in transformation. Complete response was achieved by low-dose ara-C therapy, but he relapsed 15 months later, with pancytopenia and 13.0% myeloblasts in normocellular marrow. He was treated unsuccessfully with prednisolone, metenolone, and 1-alpha-hydroxyvitamin D3 for 8 weeks. He then developed life-threatening pneumonia and was treated with recombinant human granulocyte colony-stimulating factor (rhG-CSF Filgrastim; 125 micrograms/day s.c.). The pneumonia resolved and, interestingly, he achieved a partial response, with normal blood cell counts and only a few dysmyelopoietic cells in the marrow. However, thrombocytopenia progressed when rhG-CSF administration was tapered. When the dose was increased again, leukemic blasts were found to proliferate. When rhG-CSF was discontinued, blasts rapidly decreased in the peripheral blood. Chromosomal analysis revealed a complex abnormality during the first relapse, a normal 46,XY karyotype during the partial response, and recurrence of the same complex abnormality during leukemic transformation. The stimulation index of marrow mononuclear cells cultured with rhG-CSF increased with disease progression. These findings suggest that rhG-CSF initially stimulated the selective proliferation of normal hemopoietic cells, but the evolution or selection of a leukemic clone responsive to rhG-CSF appears to have occurred subsequently.

Kostmann's syndrome is a congenital disorder characterized by impairment of myeloid differentiation in bone marrow with severe absolute neutropenia. A 17-month-old girl was admitted to the hospital with complaints of recurrent skin infections since birth and severe pneumonia of the right lung which had been resistant to antibiotics since the patient was eight months old. Anemia, severe neutropenia and maturational arrest of granulocytes at the myelocyte stage in bone marrow were detected. At the age of 20 months, a right pneumonectomy was performed because of resistant cystic infection. Postoperatively, she was diagnosed with Kostmann's syndrome. Recombinant human granulocyte-colony-stimulating factor (rhG-CSF) was administered intravenously at a dose of 3 micrograms/kg/day, gradually increasing to 60 micrograms/kg/day in sequential seven-day courses to obtain a neutrophil count of more than 500 cells/mm3. Absolute neutrophil counts increased to greater than 1000 cells/mm3 at a dose of 60 micrograms/kg/day, and at that time bone marrow aspiration revealed an increase in neutrophilic granulocytic precursors beyond the myelocyte stage. In order to maintain the neutrophil response, a dose of 20 micrograms/kg/day rhG-CSF subcutaneously was continued successfully. The patient has tolerated rhG-CSF treatment without complications, and infectious attacks have significantly decreased.

Starting from May, 1991, 35 untreated myeloma patients entered a multicentric pilot study to evaluate the feasibility of a program of PBSC transplantation for previously untreated myeloma patients. The schedule was as follows: 2 cycles of VAD followed by CY, 7 g/mq+G-CSF (Granulokine, Roche) for 14 days, to increase and collect PBSC. The subsequent conditioning regimen was Melphalan+Busulfan followed by G-CSF. As maintenance R alpha-2 IFN was given, until relapse. The median follow-up is 14 months (4-22). On April 1993, 34 patients received at least 2 cycles of VAD, 27 were submitted to PBSC collection, 22 received conditioning regimen plus PBSC and 16 of them are in the maintenance treatment with IFN. Considering 28 patients for an intention to treat evaluation (35-7 in treatment), responding patients are 71% with 46% who achieved CR. White cells and platelets raised to > 1000/mmc and > 50,000/mmc after a median period of 10 and 13 days, from CY, and 11 and 14 days from transplant, respectively. Two patients relapsed, 2 others died while in PR because of CMV epatitis and candida pneumonia. The median number of CD34+ cells and CFU-GM was 24.75 x 10(6)/kg b.w. and 28.1 x 10(4)/kg b.w. respectively. In conclusion this treatment seems to be feasible and with low toxicity, but a longer follow-up is needed to evaluate the progression free survival of the high proportion of responding patients that we observed.

We retrospectively reviewed the regimen-related toxicity associated with busulphan (1 mg/kg orally QID days -7 to -4) and cyclophosphamide (60 mg/kg IV days -3 and -2) (Bu/Cy) chemotherapy in 69 consecutive patients who underwent autologous bone marrow transplantation (ABMT). Twenty-four patients received bone marrow (BM) alone, 22 received BM plus post-transplant granulocyte-colony stimulating factor (G-CSF) and 23 received peripheral blood progenitor cells (PBPC) +/- BM plus post-transplant G-CSF. Toxicity was scored using the criteria of Bearman. Grade II and III toxicities included mucosa (38%), liver (8%), central nervous system (5%), kidney (5%), heart (3%), pericardium (2%), bladder (2%) and lung (2%). There were five treatment related deaths (7%) from pneumonitis (2) and veno-occlusive disease, pulmonary hemorrhage and sepsis (1 each). Post-transplant G-CSF (+/- PBPC) resulted in a trend (p = 0.07) towards a reduction in post-transplant stomatitis, but did not impact on the already low incidence of other organ toxicities. As Bu/Cy for ABMT is associated with minimal non-hemopoietic toxicity, the addition of other cytotoxic agents is justified in an attempt to augment the anti-tumour effect of this conditioning regimen.

We monitored the plasma elastase alpha 1-proteinase inhibitor complex levels in 21 patients with primary lung cancer who received combination chemotherapy with or without recombinant human granulocyte colony-stimulating factor (rhG-CSF), and 15 normal nonsmokers as controls. Of the 21 patients, 14 received combination chemotherapy without rhG-CSF (among them, 6 developed pneumonia) and 7 received combination chemotherapy with rhG-CSF (among them, 1 developed pneumonia). We measured peripheral WBC counts, C-reactive protein (CRP) levels, plasma elastase alpha 1-proteinase inhibitor complex (complex) levels, and complex/WBC values during cancer chemotherapy. In patients who received cancer chemotherapy without rhG-CSF and had no complications (n = 8), WBC values decreased after chemotherapy, and then gradually increased. Complex levels also decreased slightly after chemotherapy and gradually recovered. The value obtained from dividing the complex concentration by WBC count (complex/WBC value) remained stable during cancer chemotherapy. In patients who received cancer chemotherapy with rhG-CSF and had no complications (n = 6), WBC values decreased after chemotherapy, and then rapidly increased to abnormally high values. Complex levels also decreased slightly after chemotherapy and rapidly increased to abnormally high values together with the WBC counts. The complex/WBC values remained stable during cancer chemotherapy. In patients who developed pneumonia during cancer chemotherapy with or without rhG-CSF (n = 7), their complex levels, complex/WBC values, and CRP levels were elevated at the onset of pneumonia. The maximum complex levels (the highest levels during chemotherapy) were significantly higher in patients who received cancer chemotherapy with rhG-CSF and did not develop pneumonia (583.1 +/- 114.5 ng/mL) and in patients who developed pneumonia during cancer chemotherapy (516.7 +/- 113.2 ng/mL), compared with normal nonsmokers (130.2 +/- 5.5, p < 0.01) and patients who received cancer chemotherapy without rhG-CSF and did not develop complications (211.5 +/- 23.3, p < 0.01). The maximum complex/WBC values were not increased in patients who received cancer chemotherapy with rhG-CSF (0.08 +/- 0.01) and patients who received cancer chemotherapy without rhG-CSF (0.092 +/- 0.01, p < 0.01). The maximum complex/WBC values were significantly higher in patients with pneumonia (0.56 +/- 0.12) compared with normal nonsmokers (0.026 +/- 0.002, p < 0.01) and patients without complications. These findings suggest that although rhG-CSF increases total plasma elastase burden, increased release of neutrophil elastase from individual neutrophils does not take place in vivo in the absence of pneumonia.
