RESUMEN

INTRODUCTION: To clarify the pathology of children with acute encephalopathy and other neurological disorders, the involvement of high-mobility group box 1 (HMGB1), which is a representative of danger-associated molecular patterns, and angiogenesis-related growth factors were investigated. PATIENTS AND METHODS: Participants were 12 children with acute encephalopathy (influenza, rotavirus, and others), 7 with bacterial meningitis, and 6 with epilepsy disease (West syndrome). Twenty-four patients with non-central nervous system (CNS) infections as a control group were admitted to our hospital. We examined the levels of HMGB1, platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and other cytokines in the serum and cerebrospinal fluid (CSF) of the subjects. RESULTS: Serum and CSF HMGB1 levels were significantly higher in the encephalopathy and meningitis groups than in the West syndrome and control groups. CSF HMGB1 levels correlated with those of interleukin-6 and -8. CSF HMGB1 and VEGF levels were correlated, and PDGF showed a positive relationship. CONCLUSION: HMGB1 and angiogenesis-related growth factors appear to play pivotal roles in the pathophysiology of CNS infections.

RESUMEN

In this study, we assessed circulating immune cells and plasma cytokine levels in 15 pediatric patients with drug-resistant epilepsy (DRE). DRE patients had a significantly higher percentage of CD14+ monocytes positive for IL-1ß, IL-1 receptor antagonist, IL-6, and TNF-α than controls. Significantly higher intracellular levels of IFN-γ in CD4+ T cells and NK cells were also found in DRE patients. The level of IL-1ß+ CD14+ monocytes correlated with seizure frequency, and intracellular levels of IFN-γ in NKT-like cells were negatively correlated with the duration of epilepsy. Peripheral immune cells might be involved in the pathogenesis of DRE.

RESUMEN

Although migraines are common in children and adolescents, they have a robustly negative impact on the quality of life of individuals and their families. The current treatment guidelines outline the behavioral and lifestyle interventions to correct common causative factors, such as negative emotional states, lack of exercise and sleep, and obesity; however, the evidence of their effectiveness is insufficient. To create a plan for disseminating optimal pediatric headache education, we reviewed the current evidence for factors correlated with migraine. We assessed three triggers or risk factors for migraines in children and adolescents: stress, sleep poverty, and alimentation (including diet and obesity). While there is a gradual uptick in research supporting the association between migraine, stress, and sleep, the evidence for diet-related migraines is very limited. Unless obvious dietary triggers are defined, clinicians should counsel patients to eat a balanced diet and avoid skipping meals rather than randomly limiting certain foods. We concluded that there is not enough evidence to establish a headache education plan regarding behavioral and lifestyle interventions. Clinicians should advise patients to avoid certain triggers, such as stress and sleep disorders, and make a few conservative dietary changes.

RESUMEN

Several patients with beta-propeller protein-associated neurodegeneration (BPAN)/static encephalopathy with neurodegeneration in adulthood have been reported to present Rett syndrome (RTT)-like features. This report presents an individual with BPAN showing clinical features of RTT. Psychomotor delay and epilepsy onset were noted at 1 year, and regression began at 4 years. Screening of the methyl-CpG binding protein 2 (MECP2) did not show variants. At 22 years, basal ganglia iron deposits were found on magnetic resonance imaging (MRI), and the WD-domain repeat 45 gene (WDR45) variant was identified. Review of the literature showed that BPAN with RTT-like features is associated with more epileptic seizures and less deceleration of head growth, breathing irregularities, and cold extremities than classic RTT with MECP2 variants. These clinical presentations may provide clues for differentiating between these two disorders. However, both WDR45 and MECP2 should be screened in patients presenting a clinical picture of RTT without specific MRI findings of BPAN.

RESUMEN

BACKGROUND: Migraines are a broad spectrum of disorders classified by the type of aura with some requiring attentive treatment. Vasoconstrictors, including triptans, should be avoided in the acute phase of migraines with brainstem aura, in hemiplegic migraine, and in retinal migraine. This study investigated the characteristics and burden of these migraines. METHODS: Medical charts of 278 Japanese pediatric patients with migraines were retrospectively reviewed. Migraine burden of migraines with brainstem aura, hemiplegic migraines, and retinal migraine was assessed using the Headache Impact Test-6™ (HIT-6) and the Pediatric Migraine Disability Assessment scale (PedMIDAS). RESULTS: Of 278 patients screened, 12 (4.3%) patients with migraines with brainstem aura (n = 5), hemiplegic migraines (n = 2), and retinal migraine (n = 5) were enrolled in the study. All patients had migraine with/without typical aura, whereas some patients had coexisting migraine with another type of headache (chronic tension-type headache in 3 patients, and 1 each with frequent episodic tension-type headache, headache owing to medication overuse, and chronic migraine). Migraines with brainstem aura, hemiplegic migraines, and retinal migraine patients with coexisting headaches had higher HIT-6 or PedMIDAS scores, whereas migraines with brainstem aura, hemiplegic migraines, and retinal migraine patients without coexisting headache did not show high HIT-6 or PedMIDAS scores. CONCLUSION: All migraines with brainstem aura, hemiplegic migraines, and retinal migraine patients experienced migraine with or without typical aura, and some patients having other coexisting headaches also had high PedMIDAS and HIT-6 scores. PedMIDAS and HIT-6 should not be considered diagnostic indicators of migraines with brainstem aura, hemiplegic migraines, or retinal migraine. In clinical practice for headaches in children, careful history taking and proactive assessment of the aura are needed for accurate diagnosis of migraines with brainstem aura, hemiplegic migraines, and retinal migraine.

RESUMEN

BACKGROUND: Riboflavin may prevent migraine episodes; however, there is limited evidence of its effectiveness in pediatric populations. This study investigated the effectiveness of riboflavin and clinical predictors of response in children with migraines. METHODS: We retrospectively reviewed data from 68 Japanese children with migraines, of whom 52 also exhibited another type of headache. Patients received 10 or 40 mg/day of riboflavin. We evaluated the average migraine frequency per month as a baseline and after 3 months of riboflavin therapy to determine the effectiveness and clinical predictors of response. RESULTS: The frequency of migraine episodes was significantly lower at 3 months than at baseline (median, [interquartile range], 5.2 (3-7) vs. 4.0 (2-5); p < 0.01). Twenty-five patients (36.7%) showed 50% or greater reduction in episode frequency (responders), while 18 (26.5%) showed a 25%-50% reduction. We compared responders (n = 25) and non-responders (n = 43) and found no significant differences in sex, familial history, riboflavin dose, migraine type (i.e., presence or absence of aura), age at headache onset, or age at consultation. However, non-responders were more likely to have co-morbid non-migraine headaches (odds ratio, 4.11; 95% confidence interval [CI], 1.27-13.33; p = 0.02); this variable was also significant in a multivariate analysis (adjusted odds ratio, 3.8; 95% CI, 1.16-12.6; p = 0.03). Of the co-morbid headache types, only tension headaches were significant (odds ratio, 0.176; 95% CI, 0.04-0.73; p = 0.013). No adverse effects of riboflavin were identified. CONCLUSIONS: Low-dose riboflavin is safe and modestly effective for migraines in children. It may be especially beneficial for children without other co-morbid headache types.

RESUMEN

OBJECTIVE: The present study aimed to determine whether granzymes are implicated in the pathogenesis of infection-associated acute encephalopathy (AE). METHODS: We investigated granzyme and cytokine levels in the cerebrospinal fluid of patients with acute encephalopathy or complex febrile seizures (cFS). A total of 24 acute encephalopathy patients and 22 complex febrile seizures patients were included in the present study. Levels of granzymes A and B were measured using enzyme-linked immunosorbent assay, and levels of tumor necrosis factor α (TNF-α), interferon-γ (IFN-γ), interleukin 1ß (IL-1ß), IL-1 receptor antagonist (IL-1RA), IL-4, IL-6, IL-8, and IL-10 were assessed using the Bio-Plex suspension array system. RESULTS: Cerebrospinal fluid levels of granzyme A were significantly higher, and those of TNF-α and IL-1RA were significantly lower in the AE group than in the cFS group; however, no significant differences in the levels of granzyme B, IFN-γ, IL-1ß, IL-4, IL-6, IL-8, and IL-10 were observed between the 2 groups. In addition, no significant differences in granzyme A, granzyme B, or cytokine levels were observed between acute encephalopathy patients with and those without neurologic sequelae. CONCLUSIONS: Our findings indicate the involvement of granzyme A in the pathogenesis of acute encephalopathy.

RESUMEN

Adrenocorticotropic hormone (ACTH) therapy is effective for West syndrome; however, the underlying mechanism of action remains unknown. This study explored this mechanism in 5 Japanese patients with West syndrome, injected with ACTH for 28 days. Serum samples were obtained before and 30, 120, and 720 minutes after ACTH injection divided into an "early" (1-4 days) and a "late" (10-28 days) group. Responses to ACTH over time were analyzed by measuring the levels of 27 cytokines. In the early group, serum levels of interleukins-5, -9, and -17, basic fibroblast growth factor, interferon (IFN-γ), IFN-γ-inducible protein 10, chemokine ligand (CCL) 3 and 4, and platelet-derived growth factor were higher in all patients before ACTH administration than in the 720-minute time point. In the late group, no definite trend was observed except for decreased CCL2 levels after ACTH administration. These changes may correlate with mechanisms underlying the anticonvulsant effects of ACTH.

RESUMEN

In this study, the authors assessed cerebrospinal fluid cytokine levels and single-photon emission computed tomography (SPECT) findings in complex febrile seizures. This study included 23 Japanese patients with complex febrile seizures. Twenty patients underwent SPECT and 12 underwent analysis of cerebrospinal fluid cytokine levels (interleukin [IL]-6, interleukin-10, interleukin-17, interleukin-1ß, tumor necrosis factor-α, and interferon-γ); 9 patients underwent both studies. Cerebrospinal fluid cytokine levels were compared between the current complex febrile seizure patients and 30 patients with acute encephalopathy. In 17 of 20 patients, SPECT findings revealed areas of hypoperfusion, including the frontal (5), occipital (4), and lobular (4) regions, overlapping with other areas. Relative to patients with acute encephalopathy, those with complex febrile seizures exhibited significantly lower cerebrospinal fluid interleukin-6, interleukin-1ß, tumor necrosis factor-α, and interleukin-10 levels and significantly higher interleukin-17 levels. As patients with complex febrile seizures frequently exhibit abnormal SPECT findings, cerebrospinal fluid interleukin-17 levels might provide a valid biomarker to discriminate complex febrile seizures and acute encephalopathy, regardless of SPECT findings.

RESUMEN

BACKGROUND: In this study, the pathologies of acute meningitis and encephalopathy were investigated, and biomarkers useful as prognostic indices were searched for. METHODS: The subjects were 31 children with meningitis, 30 with encephalopathy, and 12 with convulsions following gastroenteritis. Control group consisted of 24 children with non-central nervous system infection. Cerebrospinal fluid cytokine analysis was performed. RESULTS: Chemokines significantly increased in the bacterial meningitis group compared with those in viral meningitis and encephalopathy groups. On comparison of interleukin(IL)-17, it increased in cases with status epilepticus in influenza-associated encephalopathy group. In the rotavirus encephalopathy and convulsions following gastroenteritis groups, IL-17 particularly increased in the convulsions following gastroenteritis group. IL-8 increased in all cases irrespective of the causative virus. CONCLUSIONS: In the encephalopathy group, IL-8 may serve as a neurological prognostic index. IL-17 was increased in the convulsions following gastroenteritis group, particularly in cases with status epilepticus, suggesting its involvement as a convulsion-related factor.

RESUMEN

No biomarker has been established as a prognostic indicator of acute encephalopathy associated with various etiological factors. In this study, we examined useful prognostic biomarkers in patients with acute encephalopathy associated with respiratory syncytial virus (RSV) infection. The subjects were 11 children with RSV-associated encephalopathy admitted to our hospital. We measured the levels of interleukin (IL)-6, brain-derived neurotrophic factor (BDNF) and nitrogen oxide (NO)x in cerebrospinal fluid collected on the day of admission. Using the pediatric cerebral performance categories (PCPC) score as a prognostic indicator, we evaluated the association between the biomarkers and neurologic prognosis. Concerning neurologic prognosis, sequelae were noted in more than 50% of the subjects. There was no association between prognosis and age/sex. Increases in the levels of all biomarkers were observed in all subjects. IL-6 and BDNF levels were correlated with PCPC score, but not with NOx. Of the biomarkers investigated, the IL-6 and BDNF levels in cerebrospinal fluid were shown to be correlated with neurologic prognosis. Because many patients with this disease had severe sequelae, assessment should be conducted by early evaluation of the biomarkers examined in this study with respect to the clinical course.

RESUMEN

INTRODUCTION: To search for an index of neurologic prognosis of children with influenza-associated encephalopathy (IAE), involvement of angiogenesis-related growth factors in the pathology was investigated. PATIENTS AND METHODS: The subjects were 11 IAE patients, 6 patients with bacterial meningitis (BM), and 24 patients with non-central nervous system infection as a control group admitted to our hospital. The correlation between the vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) levels in cerebrospinal fluid and the relationship with an index of inflammatory marker, interleukin (IL)-6, were investigated. Using the Pediatric Cerebral Performance Categories (PCPC) score as a prognostic indicator, we evaluated the association between the biomarkers and neurologic prognosis. RESULT: PDGF significantly increased in the IAE group compared with that in the BM group. Cerebrospinal fluid VEGF and PDGF increased in all IAE and BM patients compared with that in the control group, and VEGF and PDGF were positively correlated in the 2 groups. No correlation was found between the cerebrospinal fluid VEGF and PDGF levels and IL-6 level in the IAE group, whereas a correlation was found in the BM group. All these factors increased in patients with poor neurologic prognosis. DISCUSSION: It is possible that the disease state of IAE can be evaluated based on vascular endothelial disorder-related markers.

RESUMEN

BACKGROUND: Previously, we showed that fragmented Lactobacillus amylovorus CP1563 (CP1563) functions as a dual agonist of peroxisome proliferator-activated receptor α and γ in vitro and in vivo. OBJECTIVE: Here, we examined the safety and effect of CP1563 ingestion on body fat in obese class I participants in a double-blinded, placebo-controlled, randomized clinical trial (RCT). DESIGN: In the RCT, 200 participants with a body mass index (BMI) of 25-30 kg/m(2) consumed test beverages with or without 200 mg of CP1563 daily for 12 weeks. In total, 197 subjects completed the study without any adverse effects. RESULTS: Body fat percentage, whole body fat, and visceral fat were significantly decreased in the test group compared with the placebo group (p<0.001, p<0.001, and p<0.001, respectively). Triglycerides, total cholesterol, LDL-cholesterol, and diastolic blood pressure showed significant reductions in the test group compared with the placebo group (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). Additionally, significant differences in the changes in blood glucose, insulin, homeostasis model assessment-insulin resistance (HOMA-IR), and uric acid were observed between the two groups (p<0.001, p=0.004, p<0.001, and p<0.001, respectively). Improvements in anthropometric measurements and markers were observed in obese class I subjects in the test group. CONCLUSIONS: Daily consumption of beverages containing fragmented CP1563 for 12 weeks by obese class I subjects improved anthropometric measurements and markers related to lipid and glucose metabolism without any adverse effects. These results suggest that the consumption of foods containing fragmented CP1563 reduces body fat and prevents metabolic syndrome.

RESUMEN

BACKGROUND: Lactobacillus gasseri CP2305 (CP2305) is a strain of Lactobacillus isolated from a stool sample from a healthy adult that showed beneficial effects on health as a paraprobiotic. In a previous study, we demonstrated that CP2305-fermented heat-treated milk modified gut functions more than artificially acidified sour milk. Thus, the regulatory activity of the former beverage was attributed to the inactivated CP2305 cells. OBJECTIVE: The aim of this study was to elucidate the contribution of non-viable paraprobiotic CP2305 cells to regulating human gut functions. We thus conducted a randomized, placebo-controlled, double-blinded parallel group trial. DESIGN: The trial included 118 healthy participants with relatively low or high stool frequencies. The test beverage was prepared by adding 1×10(10) washed, heat-treated, and dried CP2305 cells directly to the placebo beverage. The participants ingested a bottle of the assigned beverage daily for 3 weeks and answered daily questionnaires about defecation and quality of life. Fecal samples were collected and the fecal characteristics, microbial metabolite contents of the feces and composition of fecal microbiota were evaluated. RESULTS: The number of evacuations and the scores for fecal odors were significantly improved in the group that consumed the CP2305-containing beverage compared with those of the group that consumed the placebo (p=0.035 and p=0.040, respectively). Regarding the fecal contents of microbial metabolites, the level of fecal p-cresol was significantly decreased in the CP2305 group relative to that of the placebo group (p=0.013). The Bifidobacterium content of the intestinal microbiota was significantly increased in the CP2305 group relative to that of the placebo group (p<0.008), whereas the content of Clostridium cluster IV was significantly decreased (p<0.003). The parasympathetic nerve activity of the autonomic nervous system became dominant and the total power of autonomic activity was elevated in the CP2305 group (p=0.0401 and p=0.011, respectively). CONCLUSIONS: The continuous ingestion of heat-treated CP2305 cells clearly affected intestinal functionality. This is the first report of sterilized Lactobacillus cells having a significant impact on the environment and functions of the intestinal tract. The observed effects might be due, at least in part, to the brain-gut interaction.

RESUMEN

Recent studies suggest that peroxisome proliferator-activated receptor (PPAR) activation ameliorates metabolic disorders, including dyslipidemia. To identify an effective PPAR agonist, we screened the in vitro PPARα/γ activation ability of organic solvent extracts from food-oriented bacterial strains belonging to 5 genera and 32 species, including lactic acid bacteria, and of these, Lactobacillus amylovorus CP1563 demonstrated the highest PPARα/γ agonist activity. We also found that physical fragmentation of the strain could substitute organic solvent extraction for the expression of CP1563 activity in vitro. For functional food manufacturing, we selected the fragmented CP1563 and conducted subsequent animal experiments. In an obese mouse model, we found that treatment with fragmented CP1563 for 12 weeks decreased the levels of low-density lipoprotein (LDL)-cholesterol and triglyceride in plasma, significantly decreased the atherosclerosis index, and increased the plasma high-density lipoprotein (HDL)-cholesterol level. Thus, we conclude that fragmented CP1563 may be a candidate for the prevention and treatment of dyslipidemia.

RESUMEN

The distinction between acute encephalopathy (AE) and convulsive disorders with pyrexia may be problematic. We analyzed the clinical and laboratory features in 127 children who were admitted for suspected AE. They were categorized into (1) definite acute encephalopathy group (DAEG; n = 17, abnormal findings on electroencephalography [EEG], magnetic resonance imaging, or single-photon emission computed tomography [SPECT] with prolonged impaired consciousness), (2) probable acute encephalopathy group (PAEG; n = 21, abnormal findings without prolonged impaired consciousness), and (3) nonacute encephalopathy group (NAEG; n = 89). Cerebrospinal fluid interleukin-6 (CSF IL-6), and serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatine phosphokinase levels were significantly higher in DAEG compared with NAEG but not PAEG. No significant differences were observed between DAEG and PAEG except for serum creatinine levels. In PAEG, an area of hypoperfusion was observed on SPECT images of nine patients with normal CSF IL-6 levels. AE was suspected in two PAEG patients who exhibited high CSF IL-6 levels and abnormal EEG findings without abnormal SPECT findings. All seven patients with severe neurological sequelae were categorized to DAEG. CSF IL-6 and serum AST, ALT, and creatine kinase levels may be valid predictors of typical AE; prolonged impaired consciousness is an important sign of AE. However, SPECT may not be suitable for initial diagnosis of AE.

RESUMEN

BACKGROUND: Acute rheumatic fever (ARF) is an illness caused by group A streptococcus (GAS) infection, and remains the leading cause of acquired heart disease in worldwide. Distinguishing between ARF and septic arthritis may be difficult. This report describes a case of suppurative arthritis overlapping with ARF. CASE PRESENTATION: A 4-year-old, previously healthy boy presented with fever and left leg pain. The level of anti-streptolysin O (ASO) was elevated. His throat swab cultures grew GAS, but none were detected in his synovial fluid. Magnetic resonance imaging revealed suspected arthritis and osteomyelitis. The patient was treated for septic arthritis, but was subsequently diagnosed with ARF, after the development of carditis. CONCLUSION: The clinical and laboratory features of ARF and suppurative arthritis demonstrate substantial overlap. Patients with an elevated ASO should undergo a careful cardiac examination for carditis associated with ARF by an echocardiogram.
