A phase I/II trial evaluated early administration and dose escalation of interleukin (IL)-2 with granulocyte macrophage colony stimulating factor (GM-CSF) post-transplant. Following melphalan (200 mg/m(2)) and an autologous transplant, IL-2 was initiated (day 0) and continued for 4 weeks. GM-CSF (250 mcg/m(2)/day) began on day 5. Fifteen of 19 patients completed therapy. No treatment-related deaths occurred. IL-2 (1 x 10(6) IU/m(2)/day) was not tolerated in two of six patients due to > or =grade 3 fatigue/diarrhea (n=1) or supraventricular tachycardia (n=1). The maximum tolerated dose of IL-2 was 6 x 10(5) IU/m(2)/day; this dose was well tolerated by 11 of 13 patients. Neutrophil and platelet engraftment occurred on day 13 (median; range 10-17 days) and day 13 (median; range 0-74 days), respectively. When compared to control patients, there was a marked increase in the number of CD3+ T cells (P=0.005), CD4+ T cells (P=0.01), CD8+ T cells (P=0.001) and CD4+CD25+Treg cells (P=0.015) post-transplant. Cytotoxicity directed against myeloma cells was markedly increased when compared to control patients (P=0.017). This unique trial design using early administration of IL-2 with GM-CSF during the period of lymphodepletion, demonstrated a marked increase in the number and function of early cytotoxic effector T cells, without suppression of engraftment.

Sleep-wake disturbances (SWD) are common after traumatic brain injury (TBI). In acute TBI, we recently found decreased CSF levels of hypocretin-1, a wake-promoting neurotransmitter. In the present study, we aimed to delineate the frequency and clinical characteristics of post-traumatic SWD, to assess CSF hypocretin-1 levels 6 months after TBI, and to identify risk factors for posttraumatic SWD. A total of 96 consecutive patients were enrolled within the first 4 days after TBI. Six months later, out of 76 TBI patients, who did not die and who did not move to foreign countries, we included 65 patients (86%, 53 males, mean age 39 years) in our study. Patients were examined using interviews, questionnaires, clinical examinations, computed tomography of the brain, laboratory tests (including CSF hypocretin-1 levels, and HLA typing), conventional polysomnography, maintenance of wakefulness and multiple sleep latency tests (MSLT) and actigraphy. Potential causes of post-traumatic SWD were assessed according to international criteria. New-onset sleep-wake disturbances following TBI were found in 47 patients (72%): subjective excessive daytime sleepiness (EDS; defined by the Epworth Sleepiness Scale > or = 10) was found in 18 (28%), objective EDS (as defined by mean sleep latency < 5 min on MSLT) in 16 (25%), fatigue (daytime tiredness without signs of subjective or objective EDS) in 11 (17%), post-traumatic hypersomnia 'sensu strictu' (increased sleep need of > or = 2 h per 24 h compared to pre-TBI) in 14 (22%) patients and insomnia in 3 patients (5%). In 28 patients (43% of the study population), we could not identify a specific cause of the post-traumatic SWD other than TBI. Low CSF hypocretin-1 levels were found in 4 of 21 patients 6 months after TBI, as compared to 25 of 27 patients in the first days after TBI. Hypocretin levels 6 months after TBI were significantly lower in patients with post-traumatic EDS. There were no associations between post-traumatic SWD and severity or localization of TBI, general clinical outcome, gender, pathological neurological findings and HLA typing. However, post-traumatic SWD correlated with impaired quality of life. These results suggest that sleep-wake disturbances, particularly EDS, fatigue and hypersomnia are common after TBI, and significantly impair quality of life. In almost one out of two patients, post-traumatic SWD appear to be directly related to the TBI. An involvement of the hypocretin system in the pathophysiology of post-traumatic SWD appears possible. Other risk factors predisposing towards the development of post-traumatic SWD were not identified.

We report on a 11-year-old boy who had 2 acute hemiparesis episodes over a period of 1 month. He suffered from headache and fatigue since 1 year. He could not remember neither a tick bite nor a local erythematous skin lesion. The diagnosis of neuroborreliosis was based on intrathecal production of specifics antibodies. Furthermore, the CSF/blood glucose ratio was decreased (0.14), which was rarely described. Cranial MRI showed left capsulothalamic inflammation and a vasculitis. The patient was successfully treated by ceftriaxone. Neuroborreliosis should be considered in all children with stroke-like episode, even in the absence of a history of a tick bite.

This study was aimed to evaluate the effects of recombinant human interleukin 11 (rhIL-11) and recombinant human granulocyte colony stimulating factor (rhG-CSF) in mobilization for autologous peripheral blood stem cell transplantation (APBSCT). 16 patients with non-Hodgkin's lymphoma or acute myeloblastic leukemia were given myelosuppressive chemotherapy, then were mobilized by using rhG-CSF 5 microg/(kg.d) for median 5.5 days and rhIL-11 50 microg/(kg.d) for median 4 days (experimental group) or rhG-CSF 5 microg/(kg.d) alone for median 5.5 days (control group). After mobilizing, the peripheral blood leucocyte and platelet counts, total mononuclear cells, CD34+ cells and CFU-GM counts in PBSC collection, and amount of apheresed platelet transfusion were assayed. The results showed that the peripheral blood leucocyte and platelet counts, total mononuclear cell, CD34+ cell and CFU-GM counts in PBSC collection were no significant difference between two groups (p>0.05). After APBSCT, the median time for neutrophil count>or=0.5x10(9)/L and the median time for platelet count>or=20x10(9)/L were 10.5 and 11.5 days in experimental group, while were 13 and 13 days in control group, respectively. The median amount of apheresed platelet transfusion was 3.5 unit in experimental group and 5 unit in control group. Data were significantly different between two groups (p<0.05). The adverse reactions of mobilization were mild fever, fatigue, symptoms like as common cold, poor appetite, dizziness, muscular soreness in experimental group, but only mild fever in control. These symptoms were well tolerated and overcome with drug withdrawal. It is concluded that the regimen of rhIL-11 in combination with rhG-CSF after myelosuppressive chemotherapy to mobilize PBSC is efficient and safe with rapid hematologic reconstitution and less platelet transfusions after APBSCT were used.

A 74-year-old man was hospitalized for the investigation of fever and severe general fatigue. Laboratory examinations revealed severe leukocytosis, with a leukocyte count of 29 500/mm(3). Computed tomography, ultrasonography, and endoscopic retrograde cholangiopancreatography showed a pancreatic tumor with a diameter of 70 mm. We performed distal pancreatectomy with splenectomy and gastrectomy because there was invasion of the posterior wall of the stomach. The leukocyte count decreased to 16 900/mm(3) immediately following the operation, but it began to increase again a week later, ultimately reaching 213 000/mm(3). We measured the serum granulocyte-colony stimulating factor (G-CSF) concentration and the G-CSF expressions in the resected specimens with immunohistochemistry, the findings of which confirmed the diagnosis of G-CSF-producing pancreatic cancer. G-CSF-producing tumors are considered to be in a category of rare malignant diseases originating in various organs, which carry a poor prognosis. However, G-CSF-producing pancreatic cancer is extremely rare. On postoperative day (POD) 35, an intraabdominal recurrence was detected with marked leukocytosis, and on POD 42 the patient died without receiving postoperative cancer therapy.

The objective was to design a protocol to assess work ability in people suffering ill-defined painful and disabling disorders, the outstanding prototype of which is fibromyalgia/chronic fatigue syndrome (FM/CSF).Following an extensive literature search, the mos appropriate components of current methods of assessment of physical and cognitive abilities were incorporated into the protocol, occasionally with appropriate modification to suit the specific requirements of the individual. The initial part of the assessment consists of a standard history taking, principally focusing on the patient's self-reported physical and cognitive abilities and disabilities, as well as the completion of established pain and fatigue scales, and relevant disability questionnaires. Following this, physical and cognitive abilities are objectively assessed on two separate occasions, utilizing computerized hand-held dynamometers, inclinometers, algometers, and force dynamometers. Specific work simulation tests using the industrial standards Methods-Time-Measurement testing are availed of, as is aerobic testing using the Canadian Aerobic Fitness Test (CAFT). Objective computerised neuro-cognitive testing are also utilised as an integral component of the assessment. All results are then subject to specific computerized analysis and compared to normative and standardised work-based databases. The designed system produces reliable, consistent and reproducible results. It also proves capable of detecting any inconsistencies in patient input and results, in addition to being independent of any possible assessor bias. A new protocol has been designed to determine the working capability of individuals who suffer from various chronic disabling conditions, and represents a significant step forward in a difficult but rapidly expanding area of medical practice.

Sepiapterin reductase (SR) catalyses the last step in the tetrahydrobiopterin biosynthesis pathway; it converts 6-pyruvoyl-tetrahydropterin (6-PTP) to BH(4) in an NADPH-dependent reaction. SR deficiency is a very rare autosomal recessive disorder with normal phenylalanine (Phe) concentration in blood and diagnostic abnormalities are detected in CSF. We present a 16-month-old girl with SR deficiency. From the newborn period she presented with an adaptation regulatory disorder. At the age of 3 months, abnormal eye movements with dystonic signs and at 4.5 months psychomotor retardation were noticed. Since that time axial hypotonia with limb spasticity (or rather delayed reflex development), gastro-oesophageal reflux and fatigue at the end of the day has been observed. Brain MRI was normal; EEG was without epileptiform discharges. Analysis of biogenic amine metabolites in CSF at the age of 16 months showed very low HVA and 5-HIAA concentrations. Analysis of CSF pterins revealed strongly elevated dihydrobiopterin (BH(2)), slightly elevated neopterin and elevated sepiapterin levels. Plasma and CSF amino acids concentrations were normal. A phenylalanine loading test showed increased Phe after 1 h, 2 h and 4 h and very high Phe/Tyr ratios. SR deficiency was confirmed in fibroblasts and a novel homozygous g.1330C>G (p.N127K) SPR mutation was identified. On L-dopa and then additionally 5-hydroxytryptophan, the girl showed slow but remarkable progress in motor and intellectual ability. Now, at the age of 3 years, she is able to sit; expressive speech is delayed (to 1 1/2 years), passive speech is well developed. Her visual-motor skills, eye-hand coordination and social development correspond to the age of 2 1/2 years.

Healthy donors (HDs) who were mobilized using lenograstim (LENO) and who were undergoing peripheral haematopoietic progenitor cell collection with apheresis (HPC-A) were enrolled in a surveillance protocol. In all, 184 HDs have been assessed with a median follow-up of 62 months (range 2-155). HDs received LENO at a median dose of 10 microg/kg (range 5-15). Bone pain was reported as the most frequent short-term adverse event (71.2%). Other commonly observed short-term symptoms included fatigue (19.0%), fever (5.4%), headache (27.7%), nausea (12.0%) and insomnia (22.3%). Spleen size increased in 4.3% of the donors. No vascular disorders or cardiac disease occurred. Long-term follow-up included monitoring of adverse events, neoplastic disease or other pathologies. Transit ischaemic attack occurred in one donor (39 months post-donation). One autoimmune event was reported at 28 months post-recombinant human granulocyte (rhG)-CSF (ankylosing spondylitis); one donor with a history of chronic obstructive pulmonary disease developed secondary polyglobulia (50 months post-rhG-CSF). One donor was diagnosed with lung cancer at 19 months post-donation. No haematological disease was observed. In conclusion, the short-term safety appears to be verified, whereas, although the study identified no increased risks of malignancy among HDs who received rhG-CSF, long-term safety requires more complete data sets, especially a longer follow-up and a larger number of HDs.

This phase 1 study evaluated the safety and tolerability of adjuvant treatment with subcutaneous granulocyte macrophage colony-stimulating factor (GM-CSF) administered in combination with escalating doses of thalidomide in patients with surgically resected stage II (T4), III, or IV melanoma at high risk for recurrence. Adjuvant treatment included GM-CSF 125 microg/m2 subcutaneously for 14 days and thalidomide at an initial dose of 50 mg/d, escalated in cohorts of 3 to 6 patients each to a maximum of 400 mg/d followed by 14 days of rest. Treatment was continued for up to 1 year in the absence of disease progression. Of 19 patients treated, the most common toxicities were grade 1/2 constipation (68%), fatigue (58%), neuropathy (42%), bone and joint pain (37%), and dyspnea, dizziness, injection site skin reaction, and somnolence (32% each). Thrombotic events in 3 of 19 patients (16%), including 1 treatment-related death, were the most serious adverse events and were thought to be due to thalidomide. With a median follow-up of 945 days (2.6 y), 8 (42%) patients were alive, including 1 with disease and 7 without evidence of disease. GM-CSF plus thalidomide as adjuvant therapy for patients with resected high-risk melanoma was associated with a high incidence of thrombotic events. Because life-threatening events are unacceptable in the adjuvant setting, up-front antithrombotic prophylaxis will be necessary for further evaluation of GM-CSF plus thalidomide as a viable regimen in this patient group.

Chronic fatigue syndrome (CFS) is a disabling condition characterized by unexplained chronic fatigue that impairs normal activities. Although immunological and psychological aspects are present, symptoms related to skeletal muscles, such as muscle soreness, fatigability and increased lactate accumulation, are prominent in CFS patients. In this case-control study, the phenotype of the same biopsy samples was analyzed by determining i) fibre-type proportion using myosin isoforms as fibre type molecular marker and gel electrophoresis as a tool to separate and quantify myosin isoforms, and ii) contractile properties of manually dissected, chemically made permeable and calcium-activated single muscle fibres. The results showed that fibre-type proportion was significantly altered in CSF samples, which showed a shift from the slow- to the fast-twitch phenotype. Cross sectional area, force, maximum shortening velocity and calcium sensitivity were not significantly changed in single muscle fibres from CSF samples. Thus, the contractile properties of muscle fibres were preserved but their proportion was changed, with an increase in the more fatigue-prone, energetically expensive fast fibre type. Taken together, these results support the view that muscle tissue is directly involved in the pathogenesis of CSF and it might contribute to the early onset of fatigue typical of the skeletal muscles of CFS patients.
