Recombinant human granulocyte/macrophage colony-stimulating factor (rhGM-CSF) was administered to a patient with multiple myeloma (IgA, stage IIA) who had a chemotherapy-induced bone marrow aplasia with granulocytopenia complicated by severe pneumonia and septicemia. The rhGM-CSF was given as i.v. infusions, 300-400 micrograms daily, for three weeks. The patient responded both hematologically and clinically with improved granulocyte counts and clearance of massive pulmonary infiltrates. We also observed a partial remission of the myeloma with decreasing s-IgA levels and reduced plasma cell infiltration of the bone marrow during a period of up to four months after the rhGM-CSF treatment. Immunological studies performed during and after cytokine administration showed an increase in serum interleukin-2 (IL-2) levels and HLA-DR positive T-lymphocytes indicating an activation of the immune system. It is suggested that rhGM-CSF induced immunological changes which may have contributed to the partial regression of the myeloma.

The effect of human urinary colony-stimulating factor (CSF-HU) on in-vitro phagocytosis of Legionella pneumophila, superoxide anion production and intracellular killing of Legion, pneumophila by guinea pig alveolar macrophages was studied. Alveolar macrophages when incubated with CSF-HU demonstrated enhanced phagocytic activity and superoxide production. The bactericidal activity of treated cells was enhanced when they were afterwards incubated with a low concentration of bacteria, but these cells failed to inhibit bacterial multiplication when they were incubated with bacteria in a 1:10 ratio. In vivo, an increase in the total peripheral leucocyte count in guinea pigs after intraperitoneal injection of CSF-HU occurred and this was accompanied by an increase in granulocyte and monocyte counts. A comparison of treatment of experimental Legion, pneumophila pneumonia with CSF-HU alone, ceftazidime alone and a combination revealed lower mortality rates in the group receiving combination therapy. These data suggest a possible function for CSF-HU of enhancing antibiotic therapy in Legionnaires' disease.

A 63-year old man with Felty's syndrome and pneumonia of unknown origin was treated with GM-CSF. Granulocyte counts increased and arthritis-related symptoms improved under GM-CSF. Pneumonia was treated effectively with antibiotics only during or after GM-CSF application. This suggests, that antibiotic-resistant infections can be treated effectively in patients with Felty's syndrome when granulocyte counts are raised by GM-CSF.

A phase I/II study of recombinant human granulocyte colony-stimulating factor (rhG-CSF) in 24 leukemia patients was conducted at our institute. Recombinant human G-CSF (50-200 micrograms/m2/day) was administered i.v. In seven allogeneic bone marrow transplantation (BMT) recipients, treatment with rhG-CSF was started 5 days after BMT. Neutrophils began to increase within 3 days after the start of rhG-CSF administration in five of seven patients. The mean duration necessary for recovery of neutrophils to greater than 500/microliters was 11.3 days after BMT with rhG-CSF; 26.8 days is the figure for recovery without rhG-CSF from Japanese historical data. In seven out of eight patients who received rhG-CSF administration after the first remission-induction chemotherapy, the neutrophil counts increased from less than 300/microliters to greater than 4000/microliters within 10 days. Blasts did not increase in all patients including four acute nonlymphocytic leukemia (ANLL) patients. Severe infections such as septicemia and pneumonia, which were unable to be controlled by antibiotics only, were successfully treated with rhG-CSF and antibiotics. rhG-CSF either stimulated or inhibited myeloid leukemic cells in some refractory cases. Mild bone pain occurred in one patient while receiving rhG-CSF i.v. rhG-CSF seems to have the ability to shorten the period of neutropenia, prevent infections after allogeneic BMT and remission-induction chemotherapy for acute leukemia, and support therapy for infections.

Six newborns with Listeria monocytogenes infection were admitted to the same neonatal unit between 31 October and 3 December 1985. The index case, a preterm baby, was born to a mother who was febrile with an influenza-like illness at the time of delivery. This baby presented with Listeria sepsis and pneumonia. Another child was born from whose mother L. monocytogenes was isolated from the cervix with the same serotype as that in the CSF of her newborn. In the other cases blood and cervical cultures of the mothers were negative, while Listeria was isolated from the CSF of their babies. Five out of six infants developed meningitis between 9 and 12 days after birth. All isolates were serotype 4b and indistinguishable by phage typing. All babies were successfully treated without any major sequelae. Although cross-infection was strongly suggested, the source of the outbreak could not be established. This is the first documented report of human listeriosis in Kuwait.

This paper discusses the evaluation of new macrolides and new quinolones for the treatment of Legionnaires' disease in in vitro susceptibility test, penetration to polynuclear leukocytes and treatment in an animal model. Some kinds of biological response modifier (BRMs) such as granulocyte colony stimulating factor (GCSF), monocyte CSF (M-CSF), GM-CSF, recombinant interleukin-1 (IL-1) and IL-2 were also evaluated. The antimicrobial activity (MIC) of new macrolides to Legionella pneumophila (45 strains) showed the highest activity in TE-031 (Taisho Pharmaceutical Co., Tokyo, Japan) and then rokitamycin (RKM), RU-28965 (Roussel, France), erythromycin (EM), josamycin (JM) in decreasing order of activity. According to the results of the data of cell-penetration and survival rate after treatment of guinea pigs with experimental Legionella pneumonia, the new macrolides such as TE-031, RKM and RU-28965 are expected to be more effective in the treatment of Legionnaires' disease than EM. New quinolones such as ciprofloxatin (CPFX), NY-198 (Hokuriku Pharmaceutical Co., Japan) or T-3262 (Toyama Kagaku Pharmaceutical Co., Toyama Japan) were compared to ofloxacin (OFLX), enoxacin (ENX) or rifampin (RFP) for evaluation. These drugs showed excellent activity against L. pneumophila and good penetration to polynuclear leukocytes. Regarding the treatment of guinea pig with legionella pneumonia, OFLX was the most effective, and NY-198 or T-3262 were more effective than EM treatment. The highest survival rate was obtained with IL-2 in infected guinea pigs. We also observed the efficacy of combined use of IL-2 and HR-8 10 (Horchst FRG) which is a newly developed cephem antibiotic.(ABSTRACT TRUNCATED AT 250 WORDS)

We have previously reported pulmonary eosinophils in eosinophilic pneumonia (PIE syndrome) showed two characteristics: hypodensity and nuclear hypersegmentation. Our present working hypothesis is that the eosinophil chemotactic factor and certain lymphokines may be involved in the induction of these characteristic features. Therefore, we examined whether these stimuli can induce two characteristics in vitro. Results were as follows. 1) Chemoattracts (ECF-A, histamine and PAF) can induce both nuclear hypersegmentation and hypodense eosinophils. 2) Hypodense eosinophils can be induced earlier than induction of hypersegmented nuclei (hypodense eosinophils within three hours, hypersegmented nuclei: 12 hrs). 3) Furthermore, lymphokines can not induce hypodense eosinophil. 4) However, PHA-lymphocyte culture medium (PHALCM), gamma-IFN and IL-3 + GM-CSF can induce hypersegmented nuclei but IL-2 has no effect on nuclear segmentation of eosinophils.

The effects of pneumonia on the pharmacokinetics of erythromycin administered IM and the tissue concentration changes with time were evaluated in 2-month-old calves. Pneumonia was induced by injection of Pasteurella haemolytica cultures through the thoracic wall into each lung. Six days prior to induction of pneumonia, erythromycin (15 mg/kg) was administered in a single IM dose. Erythromycin was administered again 48, 72, and 96 hours after injection of P haemolytica. On the third day of erythromycin administration (96 hours), the calves were serially euthanatized in groups of 4 calves each at 2, 5, 8, 12, 18, and 24 hours after the final dose was given. Tissue concentrations of erythromycin in kidney, liver, lung, muscle, CSF, and serum were determined. Neither the serum concentrations nor the overall pharmacokinetic values were significantly (P less than or equal to 0.05) changed by pneumonia. The concentrations of erythromycin were maximal at 5 hours for liver, muscle, and serum and at 8 hours for CSF, kidney, and lung. Serum and muscle concentrations were similar, whereas concentrations in CSF were lower than in serum and higher in kidney, liver, and lung. The lung/serum ratios were approximately 2.5 to 3 at 8 through 24 hours after IM administration. The peak concentration in lung was approximately 6 micrograms/g at 8 hours.

The therapeutic efficacy and safety of ciprofloxacin was studied in 30 patients with Pseudomonas aeruginosa infections. In 20 patients ciprofloxacin was given alone and in 10 patients (including 8 compromised hosts) in combination with an aminoglycoside (9) or azlocillin (1). Ciprofloxacin was given in doses of 500 mg orally or 200-300 mg i.v. every 12 h. In patients receiving only ciprofloxacin clinical cure with eradication of bacteria was obtained in 15 patients (75%) with infections of bone and joint (6), skin and soft tissue (4), lung (2), middle ear (2) and CSF (1). Two patients with lymphoma and Pseudomonas aeruginosa pneumonia died. In patients receiving combination therapy a definite therapeutic success was achieved in four (40%). Three patients with Pseudomonas aeruginosa septicemia died. In seven patients nine bacterial strains with decreasing susceptibility of ciprofloxacin (increase in MIC from less than or equal to 0.5 micrograms/ml to 2-16 micrograms/ml) were selected (6 Pseudomonas aeruginosa, 1 Enterobacter cloacae, 1 Serratia marcescens, 1 Staphylococcus aureus). Ciprofloxacin was well tolerated. This new quinolone seems to be suitable for single drug treatment of Pseudomonas aeruginosa infections in patients with normal host defense mechanisms, while its therapeutic potential in compromised hosts requires further evaluation.

A new patient with Leigh's syndrome (subacute necrotizing encephalomyelopathy due to pyruvate dehydrogenase complex deficiency) is presented. A Turkish boy of consanguinously married healthy parents developed progressive muscle weakness since infancy. At the age of 3 years he was unable to sit, stand or walk. Clinical examination showed general muscle weakness, hypotonia, muscle hypotrophy, bilateral ptosis, partial bilateral external ophthalmoplegia, nystagmus, intention tremor and hypoactive tendon reflexes. The EEG showed diffuse slowing, the cerebral CT scan disclosed mild hydrocephalus e vacuo. Motor nerve conduction velocity was slightly decreased, the EMG revealed signs of neuropathy. In the biopsied muscle only a mild hypotrophy of type 2 fibres was found, no abnormal mitochondria could be detected. The sural nerve was slightly abnormal: loss of large myelinated axons, loss of unmyelinated nerves. CSF protein was elevated to 80 mg/dl, protein electrophoresis revealed the pattern of markedly impaired blood-CSF barrier. Serum lactate and pyruvate were permanently elevated. In the urine the excretion of alanine was raised. The clinical state deteriorated during intercurrent infections; somnolence, vomiting and Cheyne-Stoke's respiration occurred. At the age of 3 1/2 years the child died of pneumonia. In the liver tissue a decreased activity of the pyruvate dehydrogenase complex was found. Neuropathological examination of the brain demonstrated wide-spread changes of Leigh's spongiform encephalopathy. Several enzyme deficiencies have hitherto been associated with Leigh's syndrome: This patients confirms earlier findings that a subgroup of Leigh's syndrome is caused by pyruvate dehydrogenase complex deficiency.
