RESUMO

Cytomegalovirus (CMV) infection can cause newborn morbidity and mortality; no pharmacological method of reducing CMV infection during pregnancy is currently available. In a phase 1 study in the United States, V160, a conditionally replication-defective CMV vaccine, was immunogenic and well tolerated. This placebo-controlled study (NCT03840174) investigated the safety and immunogenicity of a three-dose V160 vaccine administered over six months. A total of 18 healthy adult Japanese males (9 seronegative and 9 seropositive) were enrolled at a single center and randomized 2:1 to intramuscular V160 or placebo. In vitro, V160 induced high CMV-specific neutralizing antibody (NAb) titers (50% neutralization titer [NT50], 3651; 95% confidence interval [CI], 1688-7895) in the CMV-seronegative per-protocol immunogenicity (PPI) population one month after the third vaccine dose was administered compared with no change in the placebo arm (NT50, <94; 95% CI <94-115). The geometric mean titer ratio in the seronegative population versus baseline was 77.7 (95% CI, 23.9-252.4). CMV NAb titers in the CMV-seropositive PPI population were similar to baseline NAb titers observed in the CMV-seropositive population. V160 was well tolerated, and no vaccine viral DNA shedding was observed. In conclusion, the immunogenicity and safety profile of V160 in Japanese participants was consistent with other populations.

RESUMO

Surgical decannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO) is recommended as a standard weaning strategy considering large-sized cannulas (14-22 French) are inserted in VA-ECMO. However, we should be aware of complications such as bleeding and infection when removing an arterial cannula, especially in facilities without on-site cardiac surgical backup. Percutaneous closure devices for femoral arterial access sites are currently approved for the decannulation of a 10-French or smaller sheath. We reported a case of successful weaning off from ECMO using a combination method of a balloon catheter and a Perclose ProGlide closure device. We successfully removed the arterial cannula using this technique for four ECMO-treated patients without vascular complications or blood transfusion. Percutaneous decannulation by this method could reduce the procedural time and adverse events and be safely performed even in facilities without on-site cardiac surgical backup.

RESUMO

AIM: The quadrivalent human papillomavirus (4vHPV) vaccine has demonstrated efficacy and immunogenicity and was generally well tolerated in clinical trials conducted in Japan. We report a detailed safety analysis of injection-site reactions in female Japanese 4vHPV clinical trial participants. METHODS: This post-hoc analysis included data from 2 double-blind, placebo-controlled phase II clinical trials of a 3-dose (Day 1, Month 2, Month 6) regimen of 4vHPV vaccine in Japanese young women aged 18-26 years (N = 1021; NCT00378560) and girls aged 9-17 years (N = 107; NCT00411749). Injection-site and systemic adverse events (AEs) were monitored using vaccination report cards for 15 days after each vaccine dose; serious AEs were reported throughout the trials. Post-hoc analyses of data from these trials were performed to examine details of injection-site AEs, including day of onset, time from onset to resolution, and maximum intensity. RESULTS: Injection-site AEs were reported by 85.6% of 4vHPV vaccine recipients and 72.4% of placebo recipients, most commonly erythema, pain, pruritus, and swelling (each >5% of 4vHPV vaccine recipients). The majority of injection-site AEs had an onset within 3 days of vaccination and were mild to moderate in intensity; few 4vHPV vaccine recipients reported severe injection-site AEs (2.0% overall). All injection-site AEs resolved, and most (4vHPV: 87.5%; placebo: 92.7%) resolved within 5 days of onset. CONCLUSIONS: Most injection-site reactions are mild or moderate in intensity and of short duration. The 3-dose regimen of 4vHPV vaccine is well tolerated in Japanese female clinical trial participants based on this post-hoc analysis. These results will further support safety communication between healthcare providers and vaccine recipients regarding the HPV vaccine. TRIAL REGISTRATION: Clinicaltrials. gov: NCT00378560 and NCT00411749.

RESUMO

Human papillomavirus (HPV)-associated disease is common among men with HPV infection. A quadrivalent HPV (qHPV) vaccine has demonstrated 85.9% efficacy against HPV6/11/16/18-related, persistent (≥ 6 month) infection in a study of Japanese men aged 16-26 years old. Here, we report the results of an open-label study of the immunogenicity and tolerability of the qHPV vaccine (NCT02576054), conducted to bridge findings from Japanese men to Japanese boys aged 9-15 years old. A total of 100 boys completed a three-vaccination regimen (Day 1, and Months 2 and 6), and 99 boys were included in the primary analysis population. The rate of seroconversion at one month after vaccine Dose 3 (Month 7) was high for each type of HPV (anti-HPV6/11/16/18 seroconversion rates [95% CI]: 94.9% [85.5%, 98.3%], 99.0% [94.4%, 100.0%], 99.0% [94.5%, 100.0%], and 99.0% [94.4%, 100.0%], respectively). Moreover, anti-HPV6/11/16/18 geometric mean titers were 482.9 mMU/mL, 1052.8 mMU/mL, 3878.3 mMU/mL, and 1114.5 mMU/mL, respectively. Immune responses to the qHPV vaccine were non-inferior among Japanese boys included in the current study and compared with young Japanese men from a separate study. Injection-site reactions were the most common adverse events, and administration of the vaccine was well tolerated in Japanese boys.

RESUMO

This study for the first time assessed quadrivalent human papillomavirus (qHPV) vaccine effectiveness against HPV6/11/16/18-related high-grade cervical disease in Japanese women (16-26 years old), as previously demonstrated in overseas trials, and vaccine safety in a longer term (48-month) open-label study (NCT01544478). Participants received three doses of qHPV vaccine (Day 1, Month 2, Month 6). Effectiveness endpoints, assessed in the per-protocol population, included incidence of HPV6/11/16/18-related cervical intraepithelial neoplasia (CIN) Grade 2 or worse (CIN Grade 2 and 3, adenocarcinoma in situ, and/or cervical cancer) as primary endpoint and incidence of external genital lesions (EGLs). Disease related to other high-risk HPV types was also assessed. Adverse events (AEs) and serious AEs (SAEs) were collected from Days 1-15 after any vaccination; vaccine-related SAEs, deaths, and new medical conditions were collected throughout the study. A total of 1030 women received at least one vaccination. No cases of CIN2 or worse or EGLs were reported in the per-protocol population. Injection site-related AEs were reported in 14.5% of participants; most were mild and resolved within 15 days. Vaccine-related systemic AEs occurred in 8.6% of participants, most commonly headache (2.3%), malaise (1.7%), and pyrexia (1.3%). There were no vaccine-related SAEs; one participant discontinued due to a vaccine-related AE of mild uticaria. Overall, qHPV vaccine effectiveness against HPV6/11/16/18-related high-grade cervical disease and EGLs was indicated in Japanese women. The vaccine was well-tolerated, without new safety signals throughout the 48-month study period. Findings are consistent with overseas qHPV vaccine pivotal trials. CLINICAL TRIAL REGISTRY: clinicaltrials.gov; NCT01544478.

RESUMO

BACKGROUND: The quadrivalent (q) human papillomavirus (HPV) vaccine protects against infection and disease related to HPV types 6, 11, 16, and 18. We report efficacy, immunogenicity, and safety of qHPV vaccine in a Phase 3 study in Japanese men. METHODS: In this randomized, double-blind trial (NCT01862874), Japanese men (aged 16-26 years) were randomized in a 1:1 ratio to receive three doses of qHPV vaccine or placebo (Day 1, Month 2, Month 6). The primary efficacy endpoint was the combined incidence of HPV6/11/16/18-related persistent anogenital infection (detected at ≥2 consecutive visits ≥6 months apart), assessed in the per-protocol population of men who received all three vaccinations, and were seronegative at Day 1 and PCR negative from Day 1 to Month 7 to the relevant HPV type. Results are from the interim and final analyses. RESULTS: In total, 1124 participants were randomized. The vaccine demonstrated 83.3% (95% confidence interval: 24.9, 98.2; p = 0.007) and 85.9% (95% confidence interval: 52.7, 97.3; p < 0.001) efficacy against HPV6/11/16/18-related persistent infection in the interim and final analyses, respectively. Two cases of HPV6/11/16/18-related external genital lesions (condyloma and PIN 1) were observed in the placebo group and none in the qHPV vaccine group at study end. At Month 7, >97% of participants who received qHPV vaccine seroconverted to each of the vaccine HPV types. Most participants remained seropositive at Month 36, although the seropositivity rate declined between Months 7 and 36. Vaccination-related adverse events were reported in 60.8% and 56.5% of participants in the qHPV vaccine and placebo groups, respectively; most commonly mild to moderate injection-site pain, erythema, and swelling. Injection-site pain and swelling were more common with qHPV vaccine than placebo (each p < 0.05). CONCLUSIONS: Results suggest qHPV vaccine is efficacious against HPV6/11/16/18-related persistent infections, immunogenic, and well-tolerated in Japanese men. Clinical trial registration identifier: NCT01862874.

RESUMO

OBJECTIVES: To confirm the safety of using acetaminophen for febrile seizures (FSs) and to assess its efficacy in preventing FS recurrence during the same fever episode. METHODS: In this single-center, prospective, open, randomized controlled study, we included children and infants (age range: 6-60 months) with FSs who visited our hospital between May 1, 2015, and April 30, 2017. The effectiveness of acetaminophen was examined by comparing the recurrence rates of patients in whom rectal acetaminophen (10 mg/kg) was administered every 6 hours until 24 hours after the first convulsion (if the fever remained >38.0°C) to the rates of patients in whom no antipyretics were administered. No placebo was administered to controls. The primary outcome measure was FS recurrence during the same fever episode. RESULTS: We evaluated 423 patients; of these, 219 were in the rectal acetaminophen group, and 204 were in the no antipyretics group. In the univariate analysis, the FS recurrence rate was significantly lower in the rectal acetaminophen group (9.1%) than in the no antipyretics group (23.5%; P < .001). Among the variables in the final multiple logistic regression analysis, rectal acetaminophen use was the largest contributor to the prevention of FS recurrence during the same fever episode (odds ratio: 5.6; 95% confidence interval: 2.3-13.3). CONCLUSIONS: Acetaminophen is a safe antipyretic against FSs and has the potential to prevent FS recurrence during the same fever episode.

RESUMO

BACKGROUND: Neurological sequelae occur in 40% of patients with acute encephalopathy (AE). The early prediction of poor outcomes is critical to the initiation of appropriate treatment. The aim of the present study was therefore to elucidate prognostic factors that can be quickly and feasibly evaluated on hospital admission in patients with AE. METHODS: We analyzed data from 51 AE patients admitted to Hirakata City Hospital between January 2005 and December 2014. Age at onset, sex, underlying disease, status epilepticus (SE), presence of benzodiazepine-resistant SE (BZD-resistant SE), and basic blood serum parameters on admission were evaluated in relation to each patient's outcome. RESULTS: On univariate analysis age at onset, BZD-resistant SE, and serum aspartate aminotransferase (AST), alanine aminotransferase, lactate dehydrogenase, and platelet count varied significantly according to outcome. On multivariate analysis age at onset (≤21 months), presence of BZD-resistant SE, and AST (≥46 IU/L) were identified as independent variables associated with poor outcome. CONCLUSION: Age at onset, presence of BZD-resistant SE, and AST are associated with a poor prognosis in AE.

RESUMO

The purpose is to evaluate quantified kidney echogenicity as a biomarker for the early diagnosis of acute kidney injury (AKI) and predicting progression to chronic kidney disease (CKD) in a mouse model of ischemia-reperfusion injury (IRI). Two separate protocols of murine models of IRI were used: (1) 10, 30, and 40 min of bilateral ischemia duration and (2) 45 and 60 min of unilateral ischemia duration. Renal echogenicity was measured with ultrasound and compared with serum creatinine or urine neutrophil gelatinase-associated lipocalin (NGAL) at various timepoints after IRI. In mice subjected to 10, 30, and 40 min of bilateral ischemia, renal echogenicity increased about 2 h after IRI for all ischemia times, earlier than serum creatinine or urine NGAL. In those subjected to 45 and 60 min of unilateral ischemia, 60 min of unilateral ischemia, which represents atrophic changes 28 days after IRI, resulted in a sustained high level of echogenicity and was significantly different 24 h after IRI, while 45 min of unilateral ischemia resulted in trivial levels of histological damage 28 days after IRI. Renal echogenicity might have the potential to be a biomarker for the early diagnosis of AKI and the prognosis of CKD.

RESUMO

Carnitine is an essential nutrient for the mitochondrial transport of fatty acids. Carnitine deficiency causes a variety of symptoms in multiple organs. Patients with severe motor and intellectual disabilities often have carnitine deficiency. This study aimed to determine the correlation between constipation and carnitine deficiency in them. Patients with severe motor and intellectual disabilities at our hospital were retrospectively reviewed. The correlation between level of free carnitine and severity of constipation was examined. Constipation and non-constipation groups were compared for age; sex; body mass index; bed rest period; use of anti-epileptic drugs, valproate sodium, or enteral nutrition; and serum levels of albumin, pre-albumin, totalcholesterol, free carnitine, folic acid, and trace elements. Moreover, severity of constipation before and after carnitine supplementation was assessed. Twenty-seven patients were enrolled. Of these, 14 were assigned to the constipation group and 13 to the non-constipation group. The free carnitine level was significantly correlated with severity of constipation (R = 0.7604, p<0.01). Free carnitine was significantly lower in the constipation compared with the non-constipation group (p<0.01). No other significant differences between the groups were found. The severity of constipation was significantly relieved after carnitine supplementation (p<0.001). In conclusion, carnitine supplementation could reduce the severity of constipation.

RESUMO

A 9-valent human papillomavirus (HPV 6/11/16/18/31/33/45/52/58) virus-like particle vaccine (9vHPV) has been proven highly efficacious in preventing anogenital diseases related to HPV, in a pivotal phase III study for women aged 16-26 years. Here, we report the results of an open-label phase III study conducted to bridge the gap between the findings in women aged 16-26 years and Japanese girls aged 9-15 years. All subjects (n = 100) received a 3-dose regimen of 9vHPV vaccine on day 1 and at months 2 and 6. Anti-HPV serological assays were performed on day 1 and at months 7, 12, 24, and 30. At month 7 (4 weeks after the third dose), 100% of the subjects exhibited seroconversion for each type of HPV. Increases in geometric mean of the titers for anti-HPV 6/11/16/18/31/33/45/52/58 in the subjects were similar to those in Japanese women aged 16-26 years in a previous phase III study. Persistence of the anti-HPV response was observed for 2 years after administration of the third dose. In addition, administration of the 9vHPV vaccine was generally well-tolerated in Japanese girls.

RESUMO

BACKGROUND: The goals of this study, conducted in our secondary emergency care hospital, were to assess the effectiveness of targeted temperature management (TTM) for acute encephalopathy secondary to status epilepticus and to consider appropriate adaptations for use of TTM in this setting. METHODS: Medical records of patients admitted with acute encephalopathy to Hirakata City Hospital between January 2010 and December 2014 were retrospectively reviewed. Cases treated with TTM (36 °C) and methylprednisolone pulse (MP) therapy (TTM/MP) were compared with those treated with conventional MP regarding clinical courses and outcomes. RESULTS: In total, 20 children were retrospectively enrolled. In the TTM/MP group (10 cases) all survived intact. In the MP group (10 cases), 4 cases were left with neurological sequelae. Furthermore, in the TTM/MP group, the body temperature dropped more quickly. For pediatricians in this secondary emergency hospital, implementing the body temperature management system was not difficult. There were no complications caused by hypothermia. DISCUSSION: Use of TTM as the initial treatment for acute encephalopathy in the early-onset stage is possible in a secondary emergency care hospital. However, some acute encephalopathy cases are the so-called fulminant type; DIC or shock develops soon after onset and so it is sometimes difficult to introduce TTM. Fulminant-type patients should be transported to tertiary emergency care hospitals. Secondary emergency care hospitals must carefully select cases for TTM, keeping the possibility of transport to a tertiary emergency hospital in mind at all times.

RESUMO

UNLABELLED: Pediatric acute encephalopathy (AE) was sometimes attributed to virus infection. However, viral infection does not always result in AE. The risk factors for developing infantile AE upon virus infection remain to be determined. Here, we report an infant with AE co-infected with human herpesvirus-6 (HHV-6) and three picornaviruses, including coxsackievirus A6 (CVA6), Enterovirus D68 (EV-D68), and human parechovirus (HPeV). EV-D68 was vertically transmitted to the infant from his mother. CVA6 and HPeV were likely transmitted to the infant at the nursery school. HHV-6 might be re-activated in the patient. It remained undetermined, which pathogen played the central role in the AE pathogenesis. However, active, simultaneous infection of four viruses should have evoked the cytokine storm, leading to the pathogenesis of AE. CONCLUSION: an infant case with active quadruple infection of potentially AE-causing viruses was seldom reported partly because systematic nucleic acid-based laboratory tests on picornaviruses were not common. We propose that simultaneous viral infection may serve as a risk factor for the development of AE.

RESUMO

BACKGROUND: Cholelithiasis is one of the side-effects of ceftriaxone (CTRX). Reportedly, the cholelithiasis resolves relatively soon after cessation of CTRX, hence, it is called pseudolithiasis. Previous reports have suggested that biliary pseudolithiasis can cause not only gallstone attacks, but also severe adverse events, such as cholecystitis and pancreatitis. The purpose of this study was to prospectively elucidate the risk factors and clinical features of CTRX-associated pseudolithiasis in pediatric patients. METHODS: We prospectively examined the incidence and clinical outcome of CTRX-associated biliary pseudolithiasis. Subjects included infants and children who were admitted to hospital with acute disease. Ultrasonography was used to confirm the absence of stones and sludge in the gallbladder before CTRX therapy, and in assessment of pseudolithiasis on days 3, 5, 7 and 10 after initiation of CTRX in all subjects. The pseudolithiasis group was then compared with the non-pseudolithiasis group in terms of age, sex, CTRX dose, CTRX duration, duration of fever, fasting period, period of bed rest, and blood test results. RESULTS: Sixty patients were enrolled in the study. Eleven of them had biliary pseudolithiasis on ultrasonography (18.3%). Formation of biliary pseudolithiasis was prevalent in the fasting and bed rest groups, appearing relatively early in these groups. CONCLUSIONS: Special attention should be paid to the degree of oral intake and patient activity when CTRX is prescribed. We recommend regular ultrasonographic follow up of patients receiving CTRX, to evaluate the formation of biliary pseudolithiasis.

RESUMO

Delirious behavior (DB) in children infected with influenza virus is an important symptom associated with encephalopathy. As children with influenza-associated DB with encephalopathy may require therapy whereas children with influenza-associated DB without encephalopathy do not, distinguishing between these conditions is essential. To clarify these differences and identify the most common features of acute encephalopathy, we retrospectively reviewed the clinical course, laboratory data, magnetic resonance imaging (MRI) and electroencephalography (EEG) findings, therapy, and prognosis of 48 children with influenza exhibiting DB. Of the 48 children, 37 and 11 were diagnosed with influenza A and B, respectively. Moreover, 40 were diagnosed with DB without encephalopathy (DBNE group) and 8, with DB with encephalopathy (DBE group). Reversible splenial lesion (RESLE) was detected in 7 patients in the DBNE group, mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) in 2 patients, and a mild form of acute encephalopathy with biphasic seizures and late reduced diffusion in 1 patient in the DBE group. Serum sodium levels <136mEq/L were observed in 28 cases. Disturbance of consciousness was observed in 25 cases, seizure in 20, and slow waves on EEG in 22. Methylprednisolone pulse therapy was administered in 8 cases. No cases of neurological sequelae were observed. Although most of the clinico-radiological features of the DBNE and DBE groups did not differ substantially, marked differences were observed in the age at onset, initial neurological symptoms, duration of DB, rate of seizure, and slowing of background activity on EEG. These differences should be considered when distinguishing between DBNE and DBE in children.

RESUMO

Here we present 3 cases of childhood-onset autoimmune pancreatitis: 2 cases in boys aged 4 and 16 years, diagnosed with ulcerative colitis; 1 case in a previously healthy 10-year-old boy. All 3 boys presented with abdominal pain associated with elevated pancreatic enzyme levels. Immunoglobulin G4 levels were elevated only in the 16-year-old boy. However, pancreatic enlargement together with narrowing of the main pancreatic duct was evident on computed tomography in all 3 cases. Autoimmune pancreatitis is an uncommon disease in childhood, and only 3 cases affecting patients under 17 years of age have previously been reported in Japan. Autoimmune pancreatitis may be latent in children with pancreatitis who have chronic or intermittent abdominal symptoms. In addition, it is necessary to recognize autoimmune pancreatitis as a complication of pediatric inflammatory bowel disease. The clinical features of pediatric autoimmune pancreatitis remain unclear, and an accumulation of cases is necessary.

RESUMO

We report a 17-year-old female with juvenile neuronal ceroid-lipofuscinosis (NCL) accompanied by hypertrophic cardiomyopathy (HCM) and left ventricular noncompaction (LVNC). Within our knowledge, this is the first reported case of juvenile NCL with LVNC, and the youngest case of HCM diagnosed by ultrasound. Juvenile NCL is a progressive hereditary disease involving multi-organ accumulation of ceroid-lipofuscin; its resulting complications require prompt attention. Due to its relative rarity, its cardiac involvement is not well known. Based on findings from this patient and related juvenile NCL cases, the risk of cardiac involvement tends to increase with age; a high frequency of ventricular hypertrophy has been reported in patients aged older than 20 years of age. Medical progress and comprehensive care have led to longer survival in patients with juvenile NCL, which likely increases the incidence of cardiac involvement. In relation to HCM in other metabolic disorders, attention should be paid to arrhythmias, including repolarization disturbances, sinus node dysfunction and ventricular tachycardia. LVNC is a cardiomyopathy characterized by prominent left ventricular trabeculae and deep intratrabecular recesses, which are associated with diastolic or systolic dysfunction, thromboembolic complications and arrhythmias. From ours and other case reports, we recommend regular follow-up of NCL patients as follows: echocardiography to estimate cardiomyopathy, Holter monitoring to identify arrhythmias, and computed tomography to detect thrombosis from both ventricles. The mechanism of the HCM and LVNC associated with juvenile NCL remains unclear. Our case requires careful follow-up. Prospective studies of the cardiac involvement in juvenile NCL are necessary to further elucidate its pathomechanism.

RESUMO

Recently, many cases of children presenting reversible splenial lesions during febrile illness (RESLEF) have been reported; however, their overall clinico-radiological features are unclear. To describe the clinico-radiological features, we retrospectively reviewed the etiology (pathogen), clinical course, laboratory data, magnetic resonance imaging and electroencephalography (EEG) findings, therapy, and prognosis of 23 episodes in 22 children (1 child recurred) who presented neurological symptoms, with RESLEF. The etiologies (pathogens) varied. Seizure occurred in 7 episodes, disturbance of consciousness (DC) in 13, and delirious behavior in 18. Serum sodium levels <136 mEq/L were observed in 18 episodes. Lesions outside the splenium were found in 4 cases. Slow waves were observed on EEG in 10 episodes. Methylprednisolone pulse therapy was given in 7 cases. No case resulted in neurological sequelae. Among 23 episodes, clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) was diagnosed in 6 episodes, whereas non-MERS was observed in 17 episodes. No difference was observed in almost all the clinico-radiological features' data between the 2 groups. The largest differences were observed in the rate of purposeless movement, DC, extension of the abnormal lesions outside the splenium, and marked slowing of background activity on EEG. RESLEF exhibit a spectrum of clinico-radiological features. These results suggest that non-MERS and MERS both are a part of a larger pathological condition, which we have termed as RESLEF spectrum syndrome. Given the view that such a syndrome exists, the clinical characteristics and position of non-MERS and MERS become clear.
