    Thirty-eight instances of tetanus were treated during a recent 20 year period at the University of Mississippi and Jackson Veterans Administration Medical Centers. One patient had received a single prior dose of tetanus toxoid and the remainder had never received tetanus toxoid. Sixteen patients sought medical care for their tetanus wound prior to the onset of clinical tetanus, but none received specific antitetanus prophylaxis. The majority of tetanus wounds were located on lower extremities and often were chronic vascular ulcers. The over-all mortality was 37 per cent and survival rate was not affected by patient age, duration, location or severity of the tetanus wound or presence of associated diseases. Aggressive surgical treatment of the tetanus wound was associated with decreased mortality for uncertain reasons. Although low mortality from tetanus is possible with improved intensive care technology, the disease should be virtually preventable by the provision of proper tetanus prophylaxis to all patients at risk.

    Full Text Available Neonatal tetanus (NNT has been secondary in the whole world in the death list of diseases which can be protected by the help of vaccine. It’s an important community health problem in the less-developed countries in which pre-birth care services are limited, assisting a mother at childbirth by uneducated people in dirty atmosphere and the immunity against tetanus is not enough. Studies have shown that minor part of the cases have been expressed in most of the countries. Because of that NNT have been called as “silent/invisible murderer”. In Turkey, in the year of 2003 it has been seen 15 cases, and 12 of them have been resulted in death. The methods which will be applied to carry out the elimination of NNT are; the vaccination of pregnant women with at least two doses tetanus toxoid and providing clean birth conditions for all of the pregnant women. However, in Turkey the proportion of the women who have two doses of tetanus vaccine is 41%. To eliminate NNT in our country, all the pregnant women must be attained, the ones who are attained must be presented with qualified pre-birth care service which also includes tetanus immunity and the births must be carried out under healty conditions. As smallpox and polio eradication, NNT elimination will also be accomplished by self-sacrificing works of personnel in primary health care. [TAF Prev Med Bull 2006; 5(3.000: 229-233

    Full Text Available Introduction. Currently, in our country (Republic of Serbia tetanus is a rarely occurring disease, mainly affecting people older than 65 years of age. A small number of reported cases is mainly due to appropriate immunization. Therefore, each case of tetanus may be considered as failure of health care system to provide adequate immunization. Case outline. A 71-year-old woman was injured in her garden. She sustained laceration in the left coccygeal region. The next day the wound was treated by a surgeon, but tetanus postexposure prophylaxis was not administrated. On the fifth day following the incident, the symptoms and signs of tetanus became apparent, and the patient died two days later. Postmortem examination revealed the wound that was not adequately treated, since there was a foreign body and a dressing inserted in the wound. Signs of acute (aerobic infection were also present. Conclusion. Tetanus is a severe, potentially lethal disease that is absolutely preventable. Mistakes in immunization and surgical treatment of the wound can be considered as medical malpractice.

    2009-01-01

    Tetanus is a life threatening disease. Reported mortality for tetanus is 15-39%. Conventional treatment includes heavy sedation and artificial ventilation. Complications resulting from long term heavy sedation and artificial ventilation contribute to 60% of the total mortality caused by tetanus. In this study magnesium sulphate was used to reduce the need for sedation and artificial ventilation. Objectives of this prospective study were to determine the role of magnesium sulphate in post traumatic tetanus. The study was carried out in surgical Intensive Care at Pakistan Institute of Medical Sciences (PIMS), Islamabad from Jan 2004 to Dec 2007. Forty-four patients presented during this period and 33 patients were included in the study. All patients had tracheostomy done within 48 hours. Every patient was started Magnesium Sulphate therapy for control of spasms after sending baseline investigations. Patients were given ventilatory support when needed. All data was entered in well structured proforma. SPSS-10 was used to analyse data. Thirty-three patients were included in the study and all patients were given magnesium sulphate. Out of these, 45.5% cases were grade 4 tetanus, 73.6% and 63.3% cases did not require artificial ventilation and additional sedation respectively, 51.1% patients remained free of complications of tetanus. Overall mortality was 30.3%. Use of Magnesium Sulphate is safe and reduces the need for sedation and artificial ventilation in high grade tetanus thus contributing to survival benefit in adult post-traumatic tetanus cases.

    2009-01-01

    Full Text Available Tetanus is a neurologic disorder caused by tetanospasmin, a protein toxin elaborated by Clostridium tetani. Cephalic tetanus is a localized form of the disease causing trismus and dysfunction of cranial nerves. We report the case of a man who presented with facial trauma, complete ophthalmoplegia, exophthalmos, areactive mydriasis, and periorbital hematoma. An orbital CT revealed air bubbles in the right orbital apex. The patient was given a tetanus toxoid booster and antibiotherapy. After extraction of a wooden foreign body, the patient developed right facial nerve palsy, disorders of swallowing, contralateral III cranial nerve palsy, and trismus. Only one case of cephalic tetanus from penetrating orbital wound has been reported in literature 20 years ago. When a patient presents with an orbital wound with ophthalmoplegia and signs of anaerobic infection, cephalic tetanus should be ruled out.

    A 1-week-old infant was brought to a regional hospital with a history of recurrent seizures following lower abdominal septic skin infection. She was found to have neonatal tetanus, and a spatula test was positive. The tetanus infection was associated with a superficial skin infection, common in neonates. Treatment included sedatives (diazepam, chlorpromazine, phenobarbitone and morphine), muscle relaxants, antibiotics and ventilation in the neonatal intensive care unit. Intrathecal and intramuscular immunoglobulin were given, and the wound was treated. The infant recovered, with no seizures by the 16th day from admission, and was off the ventilator by the 18th day. This was shorter than the usual 3 - 4 weeks for neonates with tetanus at the hospital. The question arises whether tetanus immunisation should be considered in infants with skin infections, which frequently occur in the neonatal period.

    2013-11-13

    Tetanus is a severe disease that can be prevented by vaccination. In developing countries vaccination coverage is not always high. Cases still occur also in developed countries, particularly in elderly people owing to their reduced immuno protection. There are about 1 million tetanus cases per year globally. In animal studies, vitamin C has protected against various infections and bacterial toxins. In a study with rats, vitamin C protected against the purified tetanus toxin. To assess the prophylactic and therapeutic effect of vitamin C on tetanus. In May 2013 we searched the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations ); and Ovid EMBASE for this third update. Controlled trials of vitamin C as a prevention or treatment for tetanus, whether or not these were placebo controlled, in any language, published or unpublished. Two review authors independently made inclusion decisions. Both review authors independently extracted data from trial reports and assessed methodological quality. Since one of the cells in a 2 × 2 table had no events, we calculated the odds ratio (OR) and its 95% confidence interval (CI) for case fatality rate by using the Peto-method. Another of the 2 × 2 tables had no empty cells and the inverse-variance method was used to calculate its risk ratio (RR) estimate and 95% CI. We also used the Fisher's exact test to calculate the exact 95% CI for the OR of the 2 × 2 table with the empty cell. One single trial was eligible for inclusion. This non-randomised, unblinded, controlled trial undertaken in Bangladesh involved 117 tetanus patients. Vitamin C at a dosage of 1 g/day was administered intravenously alongside conventional treatment. At recruitment, the participants were stratified into two age groups and the results were reported by age. There was a significant difference in the vitamin C

  13. Factors influencing Haemagglutination Tests with Tetanus Antitoxin

    Science.gov (United States)

    Fulthorpe, A. J.

    1959-01-01

    The agglutinin titres of tetanus antitoxins tested with preserved sheep cells sensitized with tetanus toxoid have been found to be inversely proportional to the cell concentration used. The agglutinin titres per international unit of antitoxin were widely different among various electrophoretically separated globulin fractions of tetanus antitoxin. There were smaller differences between the agglutinating capacity of γ-globulin fractions of sera from different horses. With haemagglutination inhibition tests there was always a relative increase in test dose between the LA and LA/100 level of test. This relative increase was greatest where the sensitivity of the cell suspensions was high. Increased suspension sensitivity may be the result of treatment of cells with greater quantities of sensitizing antigen or of reduction in the concentration of sensitized cells in the suspension. A greater volume of serum was required to give a standard end point, when mixed with a test dose (LA) of toxin, if the mixtures were allowed to stand for increasing periods of time. These observations have been discussed. PMID:13653730

  14. Tetanus: prophylaxis and treatment of the disease.

    Science.gov (United States)

    ROSS, D E; KRAUT, J J

    1959-05-01

    Cleansing and debridement is paramount in dealing with tetanus-prone wounds (severe crushing injuries, piercing wounds, blisters and burns are outstanding examples, particularly if contaminated with dirt, grass or other debris). Prophylaxis then is relatively easy in persons who have been actively immunized by toxoid injections. For them, a "booster" injection is indicated. Use of antitoxin, however, is hazardous, whether for prophylaxis or for treatment of the disease. Since it may in itself cause severe disease, including anaphylactic reaction and serum sickness, decision to use it must be weighed against the possibility of the development of tetanus in each case. To prepare for use of it, careful history should be taken, with particular reference to sensitivity to horse dander. Dermal tests, and perhaps ophthalmic tests, for sensitivity to the serum should be carried out. Even the tests may be hazardous and precautions should be taken accordingly. If it is decided that the use of antitoxin is necessary even though the patient is sensitive to the material, desensitization must be carried out promptly, with adequate preparation for severe reaction. There is experimental evidence that antibiotics of the tetracycline group, given soon after injury, may have prophylactic effect against tetanus.

  15. Tetanus after allogeneic bone-marrow transplantation

    International Nuclear Information System (INIS)

    Kendra, J.R.; Halil, O.; Barrett, A.J.; Selwyn, S.

    1982-01-01

    A brief report is presented of a case of tetanus after allogeneic bone-marrow transplantation complicated by radiation-induced pneumonitis. A 30-year-old army sergeant received a bone-marrow transplant from his brother for the treatment of a granulocytic sarcoma after local radiotherapy to the tumour. Six years earlier he had sustained an open, compound fracture of the left tibia and fibula while on army exercise. At the time a pin and plate had been inserted and booster anti-tetanus administered. Bone-marrow transplantation was performed after total body irradiation. Cyclosporin A was given against graft-versus-host disease. Fifty four days after transplantation tetanus was diagnosed and death followed 14 days later. Necropsy disclosed radiation-induced pneumonitis, but no organisms were cultured from the lungs or the old fracture site. It is suggested that spores were incorporated into the wound site before surgery and that oxygenation around the plate became compromised after transplantation, permitting germination of dormant spores, immunosuppression allowing development of the disease.

    1992-09-01

    The levels of anti-tetanus toxoid IgG antibodies were measured in 29 lots of intravenous gamma globulin (IVIG). The antibody levels varied from 4 to 90 IU/mL (geometric mean, 18.6; 90% confidence interval, 9.7-35.7). The variation from manufacturer to manufacturer accounted for most of the observed differences among lots; there was relatively little variability among multiple lots from a single manufacturer. IVIG may be an acceptable alternative to horse or human tetanus immune globulin.

    Liefman, C E

    1980-03-01

    The protection afforded by active, passive and combined active-passive methods of immunisation against tetanus was examined in previously unimmunised horses. Three groups of horses were injected; one with tetanus toxoid alone, one with tetanus antitoxin alone and one in which the tetanus toxoid and tetanus antitoxin were injected simultaneously. The protection afforded was determined by monitoring the levels of antitoxin achieved in the horses by each of these methods. The results obtained demonstrated the effectiveness of the combined active-passive method in affording rapid and prolonged protection and enabled the examination of some of the factors involved in active and in passive immunisation when used alone. The advantages obtained by the use of the combined active-passive method in protecting unimmunised horses suddenly placed at risk to infection are outlined.

  20. Risk characterization of maternal and neonatal tetanus in view of tetanus vaccination campaigns in pakistan

    2015-01-01

    Pakistan is one of the remaining 24 countries which have not yet achieved Maternal and Neonatal Tetanus Elimination (MNTE). The country adopted high-risk approach for 56 out of 119 districts with country-wide Tetanus Toxoid (TT) provision in Routine Immunization (RI) during early 2000-2003. The TT's mass campaigns could only cover 13% of high risk districts for 2009-2011, and mostly for the Punjab province. To achieve MNT elimination, the country needs risk mapping for cost-effective intervention. Methods: We used both the quantitative and qualitative methods to conduct risk characterization. All the three available data sets (Reported EPI coverage data, PDHS 2012-13, and PSLM 2010-11) were assessed. A mix of core and surrogate indicators for risk categorization was used through ranking and scoring the aggregated data and considering the past tetanus campaigns coverage. Tetanus Toxoid (TT2+) coverage of pregnant women and delivery in health facility, both received more weightage in scoring. We based the higher and lower cuts off points for each indicator on data ranges. The districts with higher scores, i.e., 10.5 and above were ranked good followed by medium (5.5-10.4) and low performing (less than 5.5). Consultations with the national and provincial field officers were utilized to understand the local context. Results: In Pakistan, there are 139 districts out of which, 60 are the high risk districts for tetanus. Highest percentage is for Baluchistan (83%) followed by Sindh (52%), and Khyber Pakhtunkhwa (40%). Most of the Punjab is at medium risk (55%), followed by KP (52%), and Sindh (39%). Conclusion: Pakistan is at medium to high risk of MNT with a great variation at the sub-national level. Campaigns aiming to these districts may bring the country closer to MNT elimination target.

  1. Low specificity of 2 tetanus rapid tests in Cambodia.

    Science.gov (United States)

    Schlumberger, M; Yvonnet, B; Lesage, G; Tep, B

    2015-01-01

    Rapid testing for tetanus on serum or blood allows for an immediate evaluation of individual protection against tetanus in developed countries, using a "single step" immunochromatographic technique using tetanus toxoid. The specificity of these tests, compared to the reference method for tetanus, mouse serum neutralization testing, has however never been assessed in these countries, due to the difficulty to perform serum neutralization titration in mice, because of animal testing bioethical regulations. A collection of sera from adult volunteers in Cambodia, living in rural environment, was tested for tetanus antibodies by ELISA in France, and by mouse serum neutralization in Vietnam. This allowed estimating the sensitivity and specificity of 2 rapid tetanus tests, available on the market: TQS™ and Tetanotop™. The sensitivity of these tests was adequate, compared to mice serum neutralization test, for a test threshold of 0.01 IU/mL, (100% for TQS™, 91% for Tetanotop™), but their specificity was very low (1% for TQS™ and 13% for Tetanotop™). The results prove that these rapid tests for the assessment of individual protection against tetanus should not be used in the adult rural Cambodian population. Copyright © 2015 Elsevier Masson SAS.

  2. Tetanus following replantation of an amputated finger: a case report.

    Science.gov (United States)

    Hayashida, Kenji; Murakami, Chikako; Fujioka, Masaki

    2012-10-08

    Tetanus is an infectious disease caused by tetanus toxin produced by Clostridium tetani and induces severe neurological manifestations. We treated a patient who developed tetanus during hospitalization for replantation of an amputated finger. To the best of our knowledge, this is the first published case report of such an entity. A 49-year-old Japanese man had an amputation of his right middle finger at the distal interphalangeal joint region in an accident at work. His middle finger was successfully replanted, but his fingertip was partially necrotized because of crushing and so additional reconstruction with a reverse digital arterial flap was performed 15 days after the injury. Tetanus developed 21 days after replantation of the middle finger, but symptoms remitted via rapid diagnosis and treatment. In replantation after finger trauma with exposure of nerve and blood vessel bundles, concern over injuring nerves and blood vessels may prevent irrigation and debridement from being performed sufficiently; these treatments may have been insufficiently performed in this patient. It is likely that the replanted middle finger partially adhered, and Clostridium tetani colonized the partially necrotized region. Even when there is only limited soil contamination, administration of tetanus toxoid and anti-tetanus immunoglobulin is necessary when the fingers are injured outdoors and the finger nerves and blood vessels are exposed. The drugs should be administered just after replantation if the finger has been amputated. However, if clinicians pay attention to the possibility of tetanus development, treatment can be rapidly initiated.

We treated a patient who developed tetanus during hospitalization for replantation of an amputated finger. To the best of our knowledge, this is the first published case report of such an entity. Case presentation A 49-year-old Japanese man had an amputation of his right middle finger at the distal interphalangeal joint region in an accident at work. His middle finger was successfully replanted, but his fingertip was partially necrotized because of crushing and so additional reconstruction with a reverse digital arterial flap was performed 15 days after the injury. Tetanus developed 21 days after replantation of the middle finger, but symptoms remitted via rapid diagnosis and treatment. Conclusions In replantation after finger trauma with exposure of nerve and blood vessel bundles, concern over injuring nerves and blood vessels may prevent irrigation and debridement from being performed sufficiently; these treatments may have been insufficiently performed in this patient. It is likely that the replanted middle finger partially adhered, and Clostridium tetani colonized the partially necrotized region. Even when there is only limited soil contamination, administration of tetanus toxoid and anti-tetanus immunoglobulin is necessary when the fingers are injured outdoors and the finger nerves and blood vessels are exposed. The drugs should be administered just after replantation if the finger has been amputated. However, if clinicians pay attention to the possibility of tetanus development, treatment can be rapidly initiated.

    Tetanus is a rare disease in developed countries but is prevalent worldwide. It has significant morbidity and mortality. The causative agent Clostridium tetani is ubiquitous in nature. In the United States, approximately 50 to 100 cases are reported per year but rarely in immunocompetent, fully immunized patients. Of the four types of tetanus (generalized, neonatal, cephalic, and localized), cephalic is the least common. We present a case of cephalic tetanus in a 14-year-old boy who completed his primary immunizations with a video of his physical examination findings.

    /sup 125/I-labelled tetanus toxin and /sup 125/I-labelled botulinum A neurotoxin are known to be specifically bound to brain synaptosomes. In order to discriminate between active toxin and inactive admixtures present in the starting material or arising during iodination, synaptosome columns were prepared using bromacetylcellulose and/or kieselgur (Celite) as carriers. Both types of columns adsorb the toxins from low ionic strength medium and release them if the pH and ionic strength are raised. Botulinum toxin was eluted with lower ionic strength than tetanus toxin, and could be freed from nontoxic admixtures. Analysis by affinity chromatography disclosed partially toxoided tetanus toxin in both labelled and unlabelled toxin samples. High concentrations of formaldehyde (0.5%) destroyed both toxicity and affinity to the synaptosomes of tetanus toxin. Low concentrations of formaldehyde (0.05%) yielded a derivative of low toxicity which was still, however less firmly, bound to synaptosomes. Tetanus and botulinum toxin differ by their acceptors. Whereas unlabelled botulinum toxin is unable to compete with labelled tetanus toxin, unlabelled tetanus toxin slightly competes with botulinum toxin. Both labelled toxins display anomalous binding behaviour in that they cannot be displaced completely even with a large excess of unlabelled toxin.

    2014-07-01

    Full Text Available Tetanus is still a major cause of mortality and morbidity in developing countries. It occurs in children mainly in the unimmunized, due to parental ignorance and objection to vaccination. This potentially fatal disease caused by a neurotoxin, tetanospasmin released from wounds infected with Clostridium tetani, an anaerobic gram–positive bacillus. As tetanus becomes less common, cases are likely to be misdiagnosed or go unrecognized. In this case report, we present a case of tetanus in a partially immunized 2 year old girl who presented with trismus. She was treated with the recent recommendations and adequate supportive care. Detection of tetanus at a very early stage can favor lifesaving interventions. Trismus, infected wound and partially immunized/unimmunized status of a child were the key features leading to the prompt diagnosis and early treatment.

    Cephalic tetanus is a rare form of tetanus, defined by paralysis of more than one cranial nerve. The seventh cranial nerve is the most frequently involved. We report a 58-year-old man with cephalic tetanus and bilateral vestibulopathy. The patient's initial symptoms were rotatory vertigo and hypertension. He then developed trismus and cranial nerve palsies of the fifth and seventh nerves. The caloric test and vestibular evoked mygenic potentials in response to air-conducted clicks revealed absent responses on both sides, although audiometry and auditory brainstem responses were normal in both ears. To the best of our knowledge, this is the first report of involvement of the eighth cranial nerve in cephalic tetanus.

    Full Text Available Neonatal tetanus is a rare disease in developed countries, but remains common in developing countries. Pregnant women immigrating to Taiwan from developing countries may carry a risk of neonatal tetanus to the child, because of inadequate tetanus toxoid immunization and inappropriate postnatal cord care. Many young pediatricians in Taiwan are unfamiliar with this disease. Herein, we describe the clinical course of a newborn with neonatal tetanus, who was admitted with complaints of difficult feeding and muscle rigidity. After mechanical ventilation for 58 days and a prolonged hospital stay, the infant was discharged in good condition. It is important to maintain a high index of suspicion for neonatal sepsis when infants present with seizure-like symptoms, in order to allow its early diagnosis and appropriate treatment.

    Tetanus is a potentially fatal condition that is rare in urban environments but is seen in developing countries and post-natural-disaster. Therefore, the purpose of this report was to review the epidemiology, pathogenesis, and management of tetanus in the trauma patient. A thorough literature review was conducted to look for the most current and thorough guidelines on the prophylaxis and treatment of tetanus. PUBMED (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA), MEDLINE (US National Library of Medicine, National Institutes of Health; Bethesda, Maryland USA), and Cochrane Library (The Cochrane Collaboration; Oxford, United Kingdom) databases were searched for articles in English, published from 2005 to 2015, using the keywords "Tetanus," "Trauma/Surgery," and "Disaster." Controlled trials, randomized controlled trials, trials of adult patients, published guidelines, expert opinions, and review articles were selected and extracted. Current vaccination schedules in developed countries provide prophylaxis for tetanus. However, when severe natural disasters occur, many patients may not be able to provide a reliable vaccination history. In these situations, tetanus immune globulin (TIG) is indicated; if resources are not limited, both tetanus toxoid and TIG should be given to those with high-risk wounds. If resources are limited, TIG should be reserved for those that would benefit most or those least likely to have the protective antibodies. Although tetanus is a disease that has a low incidence in the developed world due to high rates of immunization, during large-scale natural disasters, compounding factors like the types of injuries, lack of medical services and supplies, and the delay in treatment associated with an already low immunization rate result in an increased incidence and outbreaks of the disease that has higher mortality in an underdeveloped society. It is important for the urban physician that cares

  14. Efficacy demonstration of tetanus vaccines by double antigen ELISA.

    Science.gov (United States)

    Rosskopf, U; Noeske, K; Werner, E

    2005-09-01

    This paper describes a double antigen ELISA (DAE) for rapid, specific and reliable assessment of the antitetanus immune status of horses and sheep. Compared with the indirect ELISA, the double antigen ELISA has the advantage of species-independent testing of sera. Thanks to its test design, it is more specific since the detected antibodies are forced to bind tetanus toxoid twice. In addition, it is very sensitive to tetanus antibodies, enabling the detection of low antibody titres, in range which is relevant for the assessment of the protective status (tetanus toxin neutralising antibodies). The detection limit of the DAE for tetanus antibodies is in the order of 10(-4) EU/ml. A comparison of in vitro results of individual sera with in vivo titres showed that horse sera with titres of 0.04 and 0.05 EU/ml in the DAE showed titres of > 0.05 IU and 0.034 IU/ml respectively during in vivo testing thus indicating good agreement. For tested sheep sera which were rated > 0.05 IU/ml in vivo, the corresponding titre in the DAE was 0.24 EU/ml. Clear tetanus antitoxin establishment of protective ELISA limits requires further comparative examination of sera with low titres (tetanus vaccines ad us. vet. As a consequence, the toxin neutralisation test (still being the standard method of choice for quantifying tetanus toxin neutralising antitoxin titres) could be replaced, since it requires too great a number of animals per test and involves considerable suffering for the animals. The test described here reduces the use of mice and guinea pigs within vaccine efficacy testing. In addition, it involves less exposure of the laboratory personnel to toxin.

Methods: A questionnaire including socio-demographic characteristics and tetanus vaccination status was applied and blood samples taken from 218 subjects between 1 and 30 June 2015. Participants were classified into five groups according to their vaccination timing. Results: The mean age of participants was 46.7±15.4 years and 134 (61.5% were women. Tetanus antitoxin levels were found weak positive in 54 (24.8% patients, positive in 44 (20.2% and strong positive in 120 (55.0%. Tetanus antitoxin level positivity was significantly associated with vaccination timing according to history. Among 105 participants who did not remember being vaccinated or who knew they were vaccinated but did not remember the date, 16 (15.2% remembered the vaccination time when their injury, military service and pregnancy were questioned specifically. Antitoxin levels decreased with increasing age independent of gender (0.9-fold increase/year. Conclusion: We found that the booster dose recommended every 10 years was not applied sufficiently. Tetanus vaccination history must be questioned in more detail among people who do not remember/know their vaccination history, with specific questions regarding pregnancy, military service and injury histories.

    Full Text Available Abstract Background Tetanus is a serious but vaccine-preventable disease and fatality rate of the disease is high in the neonates and the elderly. The aim of this study was to detect the tetanus antibody prevalence in the over sixty-year age residents of the nursing homes in Bolu. Methods A voluntary-based study was done in the residents of two nursing homes in Bolu, Turkey. Blood samples were taken from 71 volunteers residing in there nursing homes. Tetanus IgG antibodies were measured by a commercial ELISA kit. Results Among overall subjects, only 11 (15.7 % had the protective tetanus antibody titers at the time of the study. Totally, 10 subjects were examined in emergency rooms due to trauma or accidents within the last ten years and, four (40% of them had protective antibody levels. Of the remaining 61 subjects only 7 (11% had protective antibody levels (p Conclusions Tetanus antibody level is below the protective level in the majority of the over-sixty-year-age subjects residing in the nursing homes. Each over sixty-year age person in our country should be vaccinated. Until this is accomplished, at least, nursing home residents should be vaccinated during registration.

    An intramuscular injection of 8-16 Lf tetanus toxoid in water-in-oil emulsion protected adult horses against tetanus for at least 128 weeks. A booster dose of 8 Lf toxoid in aqueous solution protected them for a further period of at least 3 1/2 years. Colostral immunity protected foals for at least 10 weeks. An intramuscular injection of 8 Lf toxoid in water-in-oil emulsion given to foals from immune dams when they were 10-18 weeks old did not elicit any antibody response. They did respond, however, to a booster injection of 8 Lf toxoid in aqueous solution given 12 weeks after the first dose. New-born foals were shown to be inherently unable to respond to an injection of tetanus toxoid.

Pemerintah Kabupaten Bangkalan mendukung kebijakan Elimination Maternal Neonatal Tetanus (EMNT untuk menyelamatkan bayi dari infeksi tetanus neonatorum. Tujuan: identifikasi profil kasus tetanus pada bayi dalam mendukung kebijakan eliminasi tetanus di Kabupaten Bangkalan Provinsi Jawa Timur, Tahun 2012–2014. Metode: Studi menggunakan data sekunder tentang imunisasi Tetanus Toxoid dan Tetanus Neonatorum dari Dinas Kesehatan Kabupaten Bangkalan. Wawancara mendalam tentang pelaksanaan kebijakan EMNT kepada Penanggung jawab program imunisasi. Hasil: Setiap tahun terdapat kejadian tetanus neonatorum (TN di Kabupaten Bangkalan sehingga menyebabkan kematian karena saat hamil ibunya tidak diimunisasi TT, persalinan ditolong oleh dukun, perawatan tali pusat tidak hygienes seperti penggunaan gunting yang tidak steril, penggunaan ramuan tradisional sebagai obat. Untuk mencegah kasus tetanus neonatorum, Kabupaten Bangkalan menetapkan kebijakan EMNT sebagaimana dituangkan dalam strategi operasional yang harus dilaksanakan semua petugas kesehatan terkait. Pelaksanaan kebijakan EMNT belum sesuai harapan, karena kejadian kasus TN setiap tahun, cakupan TT semakin rendah sebanyak 61,7% pada tahun 2012 menjadi 59,18% pada tahun 2014. Demikian imunisasi DPT untuk bayi semakin rendah yaitu sebesar 92,8% pada tahun 2012 menjadi 88,0% pada tahun 2014. Kesimpulan: Kabupaten Bangkalan rawan tetanus termasuk tetanus neonatorum, karena cakupan imunisasi TT pada ibu hamil dan DPT pada bayi yang terus menurun setiap tahun. Kebijakan eliminasi TN tepat untuk meningkatkan cakupan imunisasi dan mencegah terjadinya TN pada bayi di Kabupaten Bangkalan. Saran: Pengelola Program imunisasi harus lebih aktif mensosialisasikan imunisasi TT melalui pelayanan ANC kepada ibu hamil dan DPT pada bayi untuk mencegah kasus tetanus.ABSTRACT Background

    Current political crises in the Middle East and economic discrepancies led millions of people to leave their home countries and to flee to Western Europe. This development raises unexpected challenges for receiving health care systems. Although pan-European initiatives strive for updated and optimized vaccination strategies, little data on immunity against vaccine-preventable diseases in the current refugee population exist. We quantified serum IgG against tetanus and diphtheria (TD) in n = 678 refugees currently seeking shelter in six German refugee centers. Reflecting current migration statistics in Europe, the median age within the cohort was 26 years, with only 23.9 % of female subjects. Insufficient IgG levels without long-term protection against tetanus were found in 56.3 % of all refugees. 76.1 % of refugees had no long-term protection against diphtheria. 47.7 % of subjects needed immediate vaccination against tetanus, and 47.7 % against diphtheria. For both diseases, an age-dependent decline in protective immunity occurred. We observed a considerably low rate of tetanus-protected refugees, and the frequency of diphtheria-immune refugees was far from sufficient to provide herd immunity. These findings strongly support recent intentions to implement and enforce stringent guidelines for refugee vaccination in the current crisis.

    The present study was aimed at comparing tetanus toxoid (TT)‑loaded-chitosan nanoparticles with aluminum hydroxide as a common vaccine adjuvant. Tetanus remains to be a major public health problem. Nanoparticles have been extensively used as immune adjuvants. Tetanus toxoid (TT) encapsulated in chitosan nanoparticles is considered to be a promising tetanus vaccine candidate. TT‑loaded chitosan nanoparticles were prepared by the ionic gelation method. The nanoparticles were studied by SEM for their size and morphology. In vivo study was conducted to evaluate the immunity response using mice divided into 4 groups and injected with encapsulated toxoid. The immune responses were then measured using indirect ELISA. The purity and integrity of antigen were confirmed by SDS-PAGE electrophoresis. The size of nanoparticles was estimated at 100 nm. As a result, the IgG antibody levels were 1.9, 1.76, and 0.87 in chitosan nanoparticles, aluminum hydroxide, and TT alone groups, respectively. Also, the immune responses were significantly higher in immunized groups compared to control groups vaccinated with free adjuvant vaccines (p chitosan nanoparticles were reasonable. It enhanced the immune responses as much as aluminum hydroxide adjuvant does and thus may be a good alternative candidate (Tab. 1, Fig. 3, Ref. 16).

    Maternal or neonatal tetanus causes deaths primarily in Asia and Africa and is usually the result of poor hygiene during delivery. In 2011, three neonatal tetanus cases were investigated in Papua New Guinea, and all three cases were delivered at home by untrained assistants. The babies were normal at birth but subsequently developed spasms. A neonatal tetanus case must be viewed as a sentinel event indicating a failure of public health services including immunization, antenatal care and delivery care. The confirmation of these cases led to the drafting of the Papua New Guinea National Action Plan for Maternal and Neonatal Tetanus Elimination. This included three rounds of a tetanus toxoid supplementary immunization campaign targeting women of childbearing age (WBCA) and strengthening of other clean delivery practices. The first immunization round was conducted in April and May 2012, targeting 1.6 million WBCA and achieved coverage of 77%. The government of Papua New Guinea should ensure detailed investigation of all neonatal tetanus cases reported in the health information system and perform subprovincial analysis of tetanus toxoid coverage following completion of all three immunization rounds. Efforts also should be made to strengthen clean delivery practices to help eliminate maternal and neonatal tetanus in Papua New Guinea.

    Although captive elephants are commonly vaccinated annually against tetanus using commercially available tetanus toxoid vaccines marketed for use in horses and livestock, no data exists to prove that tetanus toxoid vaccination produces measurable antibody titers in elephants. An ELISA test was created to measure antibody responses to tetanus toxoid vaccinations in 22 Asian elephants ranging in age from 24 to 56 years (mean age 39 years) over a 7-month period. All animals had been previously vaccinated with tetanus toxoid vaccine, with the last booster administered 4 years before the start of the study. The great majority of elephants had titers prior to booster vaccination, and following revaccination all elephants demonstrated anamnestic increases in titers, indicating that this species does respond to tetanus vaccination. Surprisingly older animals mounted a significantly higher response to revaccination than did younger animals. Copyright 2009 Elsevier B.V. All rights reserved.

  18. Tiff over anti-tetanus vaccine now erupted into battle. International / Philippines.

    Anti-abortionists in the Philippines have generated widespread fears in the country that tetanus toxoid used in the anti-tetanus vaccine campaign contains trace amounts of human chorionic gonadotropin (HCG) to induce abortion. The World Health Organization (WHO) notes that this widespread, unfounded fear has already resulted in a 45% drop in tetanus toxoid coverage during national immunization days in 1995 compared to 1994. Since up to 5 million women were not immunized in 1995, 300-400 more babies will contract tetanus and die in the year to come. Pro-life Philippines is ostensibly the creator and supporter of these newly-generated fears about tetanus toxoid. The mass hysteria is, however, most likely part of a church-led campaign against the government's population policies and the popularity of former Health Secretary Juan Flavier. Millions of Filipino women have for years received anti-tetanus vaccines to prevent tetanus in both mothers and their newborn children. Tetanus remains a problem for newborns in the Philippines where local midwives often use unsanitary knives to sever the umbilical cord at birth. Since the immunization drive was stepped up in 1990, the number of babies affected by tetanus has fallen from more than 25 per day in the mid-1980s to four currently. The vaccine currently supplied by UNICEF has been used for more than 50 years in many countries and is one of the basics in immunization. The Department of Health notes no unusual increase in abortions since 1990, the year the anti-tetanus drive was accelerated. Prior to 1990, anti-tetanus vaccination had been going on in the Philippines since 1983. Even WHO assurances that tetanus toxoid contains no abortifacients have failed to allay public fear. It is unfortunate that the people and groups behind this misinformation campaign have done so much damage to a decidedly beneficial and needed health program.

    Full Text Available A retrospective analysis of patients diagnosed with tetanus was conducted to evaluate the occurrence of Guillain–Barré syndrome (GBS. Two of 13 tetanus cases were complicated with GBS. Their symptoms and signs related to GBS improved markedly after a 5-day infusion of intravenous immunoglobulin. Physicians should keep in mind that GBS can be an important cause of muscle weakness in patients with tetanus.

    2013-04-01

    Full Text Available Background: Prevention of tetanus is far easier than its treatment where mortality is very high. Most cases of tetanus occur due to lack of proper vaccination against the disease and incomplete immunization on exposure. Residents in a tertiary care teaching hospital constitute the first contact physicians for patients. Aim: To assess the perception about Tetanus immunization among residents in a tertiary care teaching hospital of Pune city. Methodology: A pre tested questionnaire was used to assess the knowledge & recommendations about tetanus immunization among randomly selected 157 residents. Results: 73.25% residents were not aware of the number of doses of tetanus vaccine recommended for children under the age of 16 years. Around 50% residents were not aware of the recommended number of doses of tetanus vaccine for adults over the age of 16 years and during pregnancy. Nearly 60% of the residents considered the wound after every injury to be tetanus prone. 75.8% of residents thought burn injuries to be prone to the development of tetanus while 13.4% and 36.9% of the residents did not consider animal bite and human bite to be tetanus prone respectively. 99.4% residents considered tetanus toxoid administration in wound with rusted iron. The knowledge regarding tetanus immunization in relation to the wound categories depending on the immunization status of the patients was very poor amongst the residents. Conclusion: Better awareness and adherence of tetanus prophylaxis recommendations is needed in residents who are the first tier of health care providers in teaching hospitals.

    Full Text Available Abstract Background Although preventable, tetanus still claims tens of thousands of deaths each year. The patterns and distribution of mortality from tetanus have not been well characterized. We identified the global, regional, and national levels and trends of mortality from neonatal and non-neonatal tetanus based on the results from the Global Burden of Disease Study 2015. Methods Data from vital registration, verbal autopsy studies and mortality surveillance data covering 12,534 site-years from 1980 to 2014 were used. Mortality from tetanus was estimated using the Cause of Death Ensemble modeling strategy. Results There were 56,743 (95% uncertainty interval (UI: 48,199 to 80,042 deaths due to tetanus in 2015; 19,937 (UI: 17,021 to 23,467 deaths occurred in neonates; and 36,806 (UI: 29,452 to 61,481 deaths occurred in older children and adults. Of the 19,937 neonatal tetanus deaths, 45% of deaths occurred in South Asia, and 44% in Sub-Saharan Africa. Of the 36,806 deaths after the neonatal period, 47% of deaths occurred in South Asia, 36% in sub-Saharan Africa, and 12% in Southeast Asia. Between 1990 and 2015, the global mortality rate due to neonatal tetanus dropped by 90% and that due to non-neonatal tetanus dropped by 81%. However, tetanus mortality rates were still high in a number of countries in 2015. The highest rates of neonatal tetanus mortality (more than 1,000 deaths per 100,000 population were observed in Somalia, South Sudan, Afghanistan, and Kenya. The highest rates of mortality from tetanus after the neonatal period (more than 5 deaths per 100,000 population were observed in Somalia, South Sudan, and Kenya. Conclusions Though there have been tremendous strides globally in reducing the burden of tetanus, tens of thousands of unnecessary deaths from tetanus could be prevented each year by an already available inexpensive and effective vaccine. Availability of more high quality data could help narrow the uncertainty of tetanus

    This study aimed to estimate the immunity of the UK population to tetanus and diphtheria, including the potential impact of new glycoconjugatate vaccines, and the addition of diphtheria to the school leaver booster in 1994. Residual sera (n=2697) collected in England in 2009/10 were selected from 18 age groups and tested for tetanus and diphtheria antibody. Results were standardised by testing a panel of sera (n=150) to enable comparison with a previously (1996) published serosurvey. Data were then standardised to the UK population. In 2009, 83% of the UK population were protected (≥0.1 IU/mL) against tetanus compared to 76% in 1996 (p=0.079), and 75% had at least basic protection against diphtheria (≥0.01 IU/mL) in 2009 compared to 60% in 1996 (pdiphtheria. Higher diphtheria immunity was observed in those aged 16-34 years in 2009 compared to 1996 (geometric mean concentration [GMC] 0.15 IU/mL vs. 0.03 IU/mL, pdiphtheria in 2009 were 29% susceptible), 45-69 years (>20% susceptible) and 70+ years (>32% susceptible). Low immunity was observed in those aged 10-11 years (>19% susceptible), between the scheduled preschool and school leaver booster administration. The current schedule appears to induce protective levels; increases in the proportions protected/GMCs were observed for the ages receiving vaccinations according to UK policy. Glycoconjugate vaccines appear to have increased immunity, in particular for diphtheria, in preschool age groups. Diphtheria immunity in teenagers and young adults has increased as a result of the addition of diphtheria to the school leaver booster. However, currently older adults remain susceptible, without any further opportunities for immunisations planned according to the present schedule. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Tetanus results from infection by clostridium tetani, which is present in the faeces of animals and man therefore also in the soil. It enters the body through a wound; in the case of a neonate, this is always the raw surface of the umbilicus. The infection of this wound occurs by contamination of cord dressings by dust or soil, but in some cases mothers apply cow dung to the umbilicus. In some cases the umbilical cord is cut with an unsterile blade or even an old broken bottle. The baby is usually born at home.

  6. Replacement of the in vivo neutralisation test for efficacy demonstration of tetanus vaccines ad us. vet.

    2005-01-01

    The bacterium Clostridium (C.) tetani is an ubiquitous pathogen. This anaerobic, gram-positive bacterium can form spores and can be found in the whole environment. It enters the body via injuries of the skin and wounds where it releases the neurotoxin "tetanospasmin" (= tetanus toxin). The animals most susceptible to tetanus infection are horses and sheep. Only active immunisation by tetanus vaccine provides effective protection against tetanus intoxication. The marketing authorisation requirements stipulate that efficacy of tetanus vaccines ad us. vet. must be demonstrated in all target animal species via determination of neutralising tetanus serum antitoxin concentrations. The standard method used for this purpose is still the toxin neutralisation test (TNT), as it quantifies the tetanus toxin-neutralising effect of tetanus serum antibodies in vivo. In this test, tetanus toxin is added to dilutions of serum from vaccinated horse and sheep. The serum dilutions are then administered to mice or guinea pigs, which are observed for toxic symptoms. Against the background of animal protection, the goal of one project of the Paul-Ehrlich-Institut (Bundesministerium fuer Bildung und Forschung (Federal Ministry for Education and Research), 0312636) was to establish an alternative to the toxin neutralisation test, enabling the testing of efficacy of tetanus vaccines with serological in vitro methods. For this purpose, a so-called double antigen ELISA (DAE) was established which enables the testing of sera of different species in one assay. In addition, the sera were tested in an indirect ELISA for horses and sheep separately. Altogether, ten groups of horses and eight groups of sheep were immunised with ten animals per group each. The tetanus vaccines comprised almost all products authorised for the German market at the start of the project. 564 horse sera and 257 sheep sera were tested using the two ELISA methods. Some sera were also tested in vivo. The kinetics of

    Abstract Vaccination effectiveness is proven when the disease does not develop after a patient is exposed to the pathogen. In the case of rare diseases, vaccination effectiveness is assessed by monitoring specific antibody levels in the population. Such recurrent analyses allow the evaluation of vaccination programs. The primary schedule of diphtheria and tetanus vaccinations is similar in various countries, with differences mainly in the number and timing of booster doses. The aim of the study was to assess diphtheria and tetanus antibody concentrations in a population of healthy children. Diphtheria and tetanus antibody levels were analyzed in a group of 324 children aged 18 to 180 months. All children were vaccinated in accordance with the Polish vaccination schedule. Specific antibody concentrations greater than 0.1 IU/mL were considered protective against tetanus or diphtheria. Levels above 1.0 were considered to ensure long-term protection. Protective levels of diphtheria antibodies were found in 229 patients (70.46%), and of tetanus in 306 patients (94.15%). Statistically significant differences were found in tetanus antibody levels in different age groups. Mean concentrations and the percentage of children with high tetanus antibody titers increased with age. No similar correlation was found for diphtheria antibodies. High diphtheria antibody levels co-occurred in 72% of the children with high tetanus antibody levels; 95% of the children with low tetanus antibody levels had low levels of diphtheria antibodies. The percentage of children with protective diphtheria antibody levels is lower than that in the case of tetanus antibodies, both in Poland and abroad, but the high proportion of children without diphtheria protection in Poland is an exception. This is all the more puzzling when taking into account that Polish children are administered a total of 5 doses containing a high concentration of diphtheria toxoid, at intervals shorter than 5 years.

    Primary tetanus antitoxin responses were increasingly repressed in mice when gamma radiation doses of 100 to 400 rads were delivered by whole-body exposure prior to immunization with fluid tetanus toxoid (FTT). Nearly normal secondary antitoxin responses were obtained in mice exposed to 600 rads of gamma radiation 4 days after secondary antigenic stimulation with FTT. A rapid transition from radiosensitivity of the antibody-forming system on days 1 to 3 was followed by relative radioresistance on day 4 after the booster injection of toxoid. Studies on lymphoid cellular kinetics in popliteal lymph nodes after injection of 3 H--thymidine ( 3 H--TdR) and incorporation of 3 H--L-histidine into circulating antitoxin were carried out. Analysis of tritium radioactivity in antigen--antibody precipitates of serums 2 hr after injection of the labeled amino acid revealed maximum incorporation into antibody around day 7 after the booster in nonirradiated controls and about day 12, i.e., 8 days after irradiation, in experimental mice. The shift from radiosensitivity to relative radioresistance was attributed to a marked peak of plasma-cell proliferation in the medulla of lymph nodes on day 3. Many medullary plasma cells survived and continued to proliferate after exposure to radiation. Germinal centers were destroyed by radiation within 1 day. Since antibody formation continued after exposure to radiation and after the loss of germinal centers, this supports the view that germinal-center cells were involved more in the generation of memory cells than in antibody synthesis

    In Indonesia, the Aceh earthquake and tsunami in 2004 killed 127,000 people and caused half a million injuries, while the Yogyakarta earthquake in 2006 caused 5,700 deaths and 37,000 injuries. Because disaster-affected areas are vulnerable to epidemic-prone diseases and tetanus is one such disease that is preventable, we systematically reviewed the literature related to tetanus outbreaks following previous two natural disasters in Indonesia. Based on our findings, recommendations for proper vaccination and education can be made for future countermeasures. Using specified keywords related to tetanus and disasters, relevant documents were screened from PubMed, the WHO website, and books. Reports offering limited data and those released before 2004 were excluded. In all, 16 publications were reviewed systematically. Results show that 106 cases of tetanus occurred in Aceh, with a case fatality ratio (CFR) of 18.9%; 71 cases occurred in Yogyakarta, with CFR of 36.6%. For both outbreaks, most patients had been wounded during scavenging or evacuation after the disaster occurred. Poor access to health care because of limited transportation or hospital facilities, and low vaccination coverage and lack of awareness of tetanus risk contributed to delayed treatment and case severity. Tetanus outbreaks after disasters are preventable by increasing vaccination coverage, improving wound care treatment, and establishing a regular surveillance system, in addition to good practices of disaster management and supportive care following national guidelines. Furthermore, health education for communities should be provided to raise awareness of tetanus risk reduction.

    Overall F(ab') 2 and antitetanus-f(ab') 2 - fragments were labelled with 125 I and injected i.th. into normal juvenile cats and adult rats. One group of rats was normal; in the other, unilateral local tetanus had been induced by injection of tetanus toxin into a M. gastrocnemius. The animals were sacrificed 24 h after the i.th. injection, and tissue samples were taken for histoautoradiography. 125 I-antitetanus-F(ab') 2 permeated into the extracellular space of the spinal cord, roots, and ganglia but not into the neuronal intracellular space. 125 I-overall-F(ab') showed identical permeation behaviour. 125 I-antitetanus-F(ab') 2 reacted with tetanus toxin issuing from the motoneurons after i.th. injection, forming an immunocomplex around the motorneurons. The immunocomplex was not formed around pseudo-unipolar ganglian cells in the spinal ganglia even though some of the ganglian cells contained tetanus toxin, and 125 I-antitetanus-F(ab') 2 was present in the extracellular space. As an explanation, it was suggested that tetanus toxin does not permeate into the extracellular space through the membrane of the pseudo-unipolar ganglian cells so that immune reactions will not occur. These findings help to explain the widely divergent results of tetanus therapy by means of i.th. injection of tetanus antitoxin. Recommendations for future therapy measures are derived from the findings. (orig./MG) [de

    Full Text Available Tetanus is a disease that occurs in humans and various animal species worldwide. Tetanus toxin, after binding itself to nerve structures in the spinal cord, blocking the release of inhibitory transmitors which results in predominance of excitatory transmitors, and this manifestes itself in skeletal muscle spasm. In theory, inhibition of excitatory transmission can try to antagonize a number of ways: by stimulating inhibitory transmission with application inhibitory transmitors, inhibition of excitatory transmission by application of antagonists of excitatory transmitors and combination of antagonists of excitatory transmitors. Bearing this in mind, we attempted to normalize the disorders by tetanus toxin with the use of caroverine, an antagonist of excitatory transmitors, alone and in combination with aminooxyacetic acid (substance that increases the level of GABA. Experiments were conducted on albino mice of both sexes, weight 20-25 g. The experimental tetanus was induced by application of tetanus toxin. The application of caroverine and combination with aminooxyacetic acid was carried out 24 hours after application of tetanus toxin, once per day, until the death. Caroverine, given alone in a dose of 1,2 mg/kg significantly prolonged the LD50 period of mice with experimental tetanus, so the obtained results can be said that its application only at this dose proved to be effective. The combination with aminooxyacetic acid was gave an insignificant extension of mice’s dying time with experimental tetanus in the trial, compared to the control group. Key words: tetanus, tetanus toxin, transmitors, caroverine, aminooxyacetic acid

    A cross-sectional descriptive study was conducted from medical data of inpatients with tetanus in the Department of Infectious and Tropical Diseases of the University Hospital of Treichville in Abidjan from January 2003 to December 2007. In five years, 221 cases of tetanus have been hospitalized. The tetanus gateway was found in 188 patients (85%). Tetanus gateway linked to care was found in 22 patients (11.7%). Acts of care in question were intramuscular injections (10 cases) and operative procedures (12 cases). Concerning medical care by intramuscular injection, quinine (four cases), sulfadoxine-pyrimethamine (one case), and long-acting penicillin (one case) were the identified drugs. The operative procedures mainly involved were skin sutures (nine cases), cures of hernia (two cases), and flattening of Fournier's gangrene (one case). The average incubation period was 9.5 days. The invasion lasted for an average of 1.8 days. On admission, tetanus was immediately generalized for all patients with the presence of paroxysms in 20 patients (90.9%). The lethality of tetanus related care was 54.5%. The death rate in the first 48 hours of hospitalization was estimated at 83.3%. The average length of hospital stay was 14.6 days. Health workers should be involved in the prevention of tetanus in improving the quality of care and especially in reducing intramuscular injections. Also, any patient not immunized against tetanus should receive anti-tetanus serum and an update of its tetanus vaccine before any invasive procedures.

    To assess the effect of the Expanded Program on Immunization (EPI) in rural Africa, blood samples were collected in two Kenyan sublocations. Serum antibodies against tetanus toxoid were measured in 155 individuals 1-70 years of age. Titers greater than the protective level of 0.01 IU/ml were found...... in 47% of the population. Protection was significantly higher in children born after the launching of the EPI (68%) and in women who had been at childbearing age since then (69%). Significantly lower protection was demonstrated in other age and sex-groups. The level of protection in children was equal...... in the two populations, whereas protection in fertile women was significantly lower in the population living a long distance from a health center. Diphtheria anti-toxin was measured in the samples from one sublocation, and 70 of 84 individuals (83%) had antibody levels greater than the protective level...

    Full Text Available Lichen striatus (LS is an uncommon, acquired, self-limiting, linear inflammatory dermatosis. The eruption typically presents as pink or tan papules along Blaschko’s lines. It usually occurs in children, rarely affects adults. The rashes usually suddenly emerge in a single extremity and may regress within a few months or years. The incidence is slightly higher among women. The etiology of LS is not exactly known, however, it is thought to be a T cell-mediated autoimmune reaction. Trauma, infection, pregnancy, drugs, vaccination, and atopy have been reported as triggering factors. In the literature, four cases of LS developing after vaccination (3 children and 1 adult have been reported. It was the only reported adult case of LS developing after hepatitis B virus vaccination. Herein, we present a 36-year-old woman with LS which was thought to be triggered by a tetanus vaccine.

    We report the uncommon clinical course of tetanus in a completely immunized 14-year-old boy. His initial symptoms, which included a flaccid paralysis, supported a diagnosis of botulism. Preliminary mouse-test results with combined botulinum antitoxins A, B, and E, obtained from tetanus-immunized horses, backed this diagnosis. The change in his clinical course from paralysis to rigor and the negative, more specific, botulinum mouse test with isolated botulinum antitoxins A, B, and E, obtained from nonvaccinated rabbits, disproved the diagnosis of botulism. Tetanus was suspected despite complete vaccination. The final results of a positive mouse test performed with isolated tetanus antitoxin confirmed the diagnosis. Adequate treatment was begun, and the boy recovered completely.

    Tetanus Neonatorum is an infectious disease that can be prevented by immunization. The number of Tetanus Neonatorum cases in East Java Province is the highest in Indonesia until 2015. Tetanus Neonatorum data contain over dispersion and big enough proportion of zero-inflation. Negative Binomial (NB) regression is an alternative method when over dispersion happens in Poisson regression. However, the data containing over dispersion and zero-inflation are more appropriately analyzed by using Zero-Inflated Negative Binomial (ZINB) regression. The purpose of this study are: (1) to model Tetanus Neonatorum cases in East Java Province with 71.05 percent proportion of zero-inflation by using NB and ZINB regression, (2) to obtain the best model. The result of this study indicates that ZINB is better than NB regression with smaller AIC.

    Tetanus is an acute, toxin-mediated disease caused by Clostridium tetani infection. Under favorable anaerobic conditions, such as in the unclean environment, necrotic wounds, this ubiquitous bacillus may produce tetanospasmin, an extremely potent neurotoxin. A 38-year-old man was admitted to an emergency room, at Zainoel Abidin General Hospital, with the main complaint of back-muscle stiffness. Based on physical examination, he was fully alert with a slightly rapid breathing, trismus with the maximum oral cavity opening was only about one finger width, but rhisus sardonicus was not evident. Ten days before admission, while gardening, his left foot accidentally stabbed by wooden tree stake. We immediately started a single dose of tetanus immunoglobulin followed by intravenous metronidazole, penicillin G, and intravenous diazepam. Tetanus diagnosed by physical clinical finding. The management of tetanus patients including the use of immunoglobulin and antibiotic therapy, analgesia, sedation and neuromuscular blockade management and mechanical ventilation, the care was delivered outside the Intensive care unit.

    Accurate determination of concentration of immunoglobulin (IgG) to tetanus toxoid is important in order to evaluate the immunogenicity of tetanus toxoid vaccines, immune competence in individual patients and to measure the prevalence of immunity in populations. Surface modified polyacrylonitrile (PAN) fibers were evaluated as a matrix to develop highly sensitive method for the detection of anti-tetanus antibody in a sandwich ELISA format. In the proposed method tetanus toxoid immobilized on modified PAN fibers was used to detect anti-tetanus antibody (raised in horse hence represented as horse anti-tetanus toxoid or HAT-Ab) with horse raddish peroxidase enzyme conjugated with Rabbit anti-Horse IgG (RAH-HRP) as the label within 2.5h. A sigmoidal pattern for the detection of different concentration of antibody ranging from 1.0 to 0.0001 IU mL(-1) was validated. The immunoassay recorded a very high sensitivity as concentration as low as 0.0005 IU mL(-1) of HAT-Ab was detected. The intra- and inter-assay precision for 3 parallel measurements of 0.01 and for 0.001 IU mL(-1) of antibody varied from 5.4% to 11% and 5.7% to 20% respectively. PAN fibers were also used to qualitatively access the presence of different level of anti-tetanus antibody spiked in human blood. Seroepidemiological studies to measure the immunity against tetanus were conducted with twenty-five human beings belonging to various age groups using modified PAN-ELISA. The sensitivity, specificity and the reproducibility of the developed immunoassay indicate the potential application of modified PAN fibers in the field of immunodiagnostics.

    Full Text Available Abstract Background Neonatal tetanus (NT is still considered as one of the major causes of neonatal death in many developing countries. The aim of the present study was to assess the characteristics of sixty-seven infants with the diagnosis of neonatal tetanus followed-up in the Pediatric Infectious Diseases Ward of Dicle University Hospital, Diyarbakir, between 1991 and 2006, and to draw attention to factors that may contribute (or may have contributed to the elimination of the disease in Diyarbakir. Methods The data of sixty-seven infants whose epidemiological and clinical findings were compatible with neonatal tetanus were reviewed. Patients were stratified into two groups according to whether they survived or not to assess the effect of certain factors in the prognosis. Factors having a contribution to the higher rate of tetanus among newborn infants were discussed. Results A total of 55 cases of NT had been hospitalized between 1991 and 1996 whereas only 12 patients admitted in the last decade. All of the infants had been delivered at home by untrained traditional birth attendants (TBA, and none of the mothers had been immunized with tetanus toxoid during her pregnancy. Twenty-eight (41.8% of the infants died during their follow-up. Lower birth weight, younger age at onset of symptoms and at the time admission, the presence of opisthotonus, risus sardonicus and were associated with a higher mortality rate. Conclusion Although the number of neonatal tetanus cases admitted to our clinic in recent years is lower than in the last decade efforts including appropriate health education of the masses, ensurement of access to antenatal sevices and increasing the rate of tetanus immunization among mothers still should be made in our region to achieve the goal of neonatal tetanus elimination.

    The hyperadrenergic syndrome that occurs in tetanus is characterised by hypertension, tachycardia, and increased systemic arteriolar resistance. A 74 year old man with tetanus was found to have very high catecholamine concentrations--as high as those in phaeochromocytoma--and the fluctuations in blood pressure and heart rate were measured to see whether they paralleled changes in the catecholamine values. A labetalol infusion of 0.25-1 mg/min gradually stabilised the cardiovascular disturbanc...

    The Lf-unit, which is used in the control of diphtheria and tetanus toxoid production and in some countries also to follow immunization of horses for production of antitoxins, has hitherto been defined by means of antitoxin preparations. A diphtheria toxoid and a tetanus toxoid preparation, both freeze-dried, were examined in an international collaborative study for their suitability to serve as reference reagents in the flocculation tests and for defining the Lf-units. It was shown that flocculation tests using the reference toxoids are very reproducible and reliable and the WHO Expert Committee on Biological Standardization established: the toxoid called DIFT as the International Reference Reagent of Diphtheria Toxoid for Flocculation Test with a defined content of 900 Lf-units of diphtheria toxoid per ampoule; and the toxoid called TEFT as the International Reference Reagent of Tetanus Toxoid for Flocculation Test with a defined content of 1000 Lf-units of diphtheria toxoid per ampoule.

    Knowledge of tetanus immunity in equine patients is crucial in cases of injuries, elective surgeries, or when effective vaccination protocols are to be designed. The Fassisi® TetaCheck is a stall-side rapid test which was developed to address these issues. The purpose of the present study was to evaluate its performance parameters. To this end, the qualitative test results obtained by two blinded observers were compared to tetanus toxoid antibody levels from 99 serum samples, measured with a double antigen ELISA. Additionally the colour intensities of the test window were quantified using a camera and photo editing software. Assuming that the protective level of tetanus toxoid antibodies is ≥ 0.1 IE/ml, the tetanus quick stick (TQS) showed a sensitivity of 83.6% and a specificity of 100%. almost perfect (K = 0.88). Exchanging the observer did not affect the interpretation of theTQS (K = 0.80; K = 0.84). The definition of five distinct colour intensities of the "test window" enabled a clear differentiation of unprotected individuals from those with a protective immunity. There was a linear relationship between the objectively measured colour intensities and the tetanus toxoid antibody concentration (r2 = 0.74). The TQS thus proved to be a robust and reliable test in the stall-side assessment of tetanus immunity in horses. Its implementation in equine daily practice can help to avoid unnecessary immunizations in adult horses and therefore minimize vaccination side effects.

    Full Text Available Samples from 20 lots of diphtheria-tetanus (adult use dT vaccine and from 20 lots of diphtheria-tetanus-pertussis (DTP vaccine were used to standardize and validate the in vitro toxin binding inhibition (ToBI test for the immunogenicity test of the tetanus component. The levels of tetanus antitoxin obtained by ToBI test were compared to those obtained using the toxin neutralization (TN test in mice routinely employed to perform the quality control of the tetanus component in adsorbed vaccines. The results ranged from 1.8 to 3.5 IU/ml for dT and 2 to 4 IU/ml for DTP by ToBI test and 1.4 to 3 IU/ml for dT and 1.8 to 3.5 IU/ml for DTP by TN in mice. These results were significantly correlated. From this study, it is concluded that the ToBI test is an alternative to the in vivo neutralization procedure in the immunogenicity test of the tetanus component in adsorbed vaccines. A substantial refinement and a reduction in use of animals can be achieved.

    Pakistan is one of the 34 countries that have not achieved the neonatal tetanus (NT) global elimination target set by the World Health Organization (WHO). NT, caused by Clostridium tetani, is a highly fatal infection of the neonatal period. It is one of the most underreported diseases and remains a major but preventable cause of neonatal and infant mortality in many developing countries. In 1989, the World Health Assembly called for the elimination of NT by 1995, and since then considerable progress has been made using the following strategies: clean delivery practices, routine tetanus toxoid (TT) immunization of pregnant women, and immunization of all women of childbearing age with three doses of TT vaccine in high-risk areas during supplementary immunization campaigns. This review presents the activities, progress, and challenges in achieving NT elimination in Pakistan. A review of the literature found TT vaccination coverage in Pakistan ranged from 60% to 74% over the last decade. Low vaccination coverage, the main driver for NT in Pakistan, is due to many factors, including demand failure for TT vaccine resulting from inadequate knowledge of TT vaccine among reproductive age females and inadequate information about the benefits of TT provided by health care workers and the media. Other factors linked to low vaccination coverage include residing in rural areas, lack of formal education, poor knowledge about place and time to get vaccinated, and lack of awareness about the importance of vaccination. A disparity exists in TT vaccination coverage and antenatal care between urban and rural areas due to access and utilization of health care services. NT reporting is incomplete, as cases from the private sector and rural areas are underreported. To successfully eliminate NT, women of reproductive age must be made aware of the benefits of TT vaccine, not only to themselves, but also to their families. Effective communication strategies for TT vaccine delivery and

    In the United Republic of Tanzania, the incidence of non-neonatal circumcision-related tetanus is probably underreported. We analysed charts and extracted information on outcome and wound location for non-neonatal cases of tetanus admitted to the intensive care unit of Bugando Medical Centre between 2001 and 2016. Bugando Medical Centre, which is one of four teaching referral hospitals in the United Republic of Tanzania, has a 13-bed intensive care unit that manages all admitted patients with tetanus. Within the United Republic of Tanzania, formal programmes of tetanus immunization are targeted at infants or women. From our inpatient logs, we identified six patients with non-neonatal tetanus among male patients with a recent history of circumcision. Only one of these patients had been circumcised within a subnational programme of voluntary medical male circumcision. The other five had been circumcised outside of the programme - e.g. at small rural dispensaries or by a traditional provider with no formal medical training. The six patients were aged 11-55 years and five (83%) of them died in hospital - all of overwhelming sepsis. Within the Tanzanian programme of voluntary medical male circumcision, education on wound hygiene probably helps to reduce the incidence of non-neonatal circumcision-related tetanus. The corresponding incidence among the boys and men who are circumcised beyond this subnational programme is probably higher. The training of all circumcision providers in wound care and a vaccination programme to ensure that male Tanzanians receive tetanus immunization post-infancy are recommended.

    Full Text Available Tetanus antitoxin is quantified in Cuba at blood banks, from the serum of immunized donors, to produce aspecific human gamma globulin. A heterogeneous indirect immunoenzymatic assay is used, using the serum as analytical sample. The possible use of plasma obtained from plasmapheresis as alternative sample was evaluated in this research, to minimize the volume of total blood extracted to the donors. One hundred plasma donors who came to donate between October and November 2013 were selected by simple random sampling. Serum sample was obtained for extraction of 5 mL of blood, deposited in dry glass tube. While the other sample took 1.5 mL of plasma in a plastic tube with cover, at the end of the donation directly of the unit of plasma collected. Comparison of the difference between the means of both groups was done using SPSS for Windows. It was found that the values obtained in serum were bigger than those obtained in plasma. Difference between the means of both groups was statistically significant (p 0.00. It is not advisable to use the obtained plasma of the plasmapheresis as analytic sample in this assay.

    The aim of our study was to investigate the anti-tetanus and anti-diphtheria antibody titres and the placental transfer of these antibodies in a group of vaccinated and unvaccinated mothers and their term or preterm offsprings. Anti-tetanus and anti-diphtheria toxoid IgG antibodies were measured quantitatively by ELISA in 91 infant-mother pairs. Protective concentrations of anti-tetanus and anti-diphtheria were found in 58.3 and 50% of mothers in the unvaccinated group and 94.5 and 85.5% of the mothers in the vaccinated group. Protective concentrations were found in 63.9 and 50% of cord samples, respectively, in the unvaccinated group and in 96.4 and 85.5% of cord samples, respectively, in the vaccinated group (p = 0.0001). There were no differences in the maternal and cord geometric mean concentrations (GMCs) of anti-toxoid antibodies between those who received two doses or one dose of Td. The GMCs of maternal and cord anti-tetanus and anti-diphtheria were statistically similar between preterm and term groups. Placental transfer ratios (TR) for anti-tetanus and anti-diphtheria were 175 and 150%, respectively, in the preterm group and 213 and 178%, respectively, in the term group. There was a strong correlation between maternal and cord anti-toxoid antibody levels. Maternal vaccination was the only predictor of having protective concentrations of anti-toxoid antibodies in cord blood. Vaccinating pregnant women with at least one dose of Td would confer protection for both the term and preterm infant-mother pairs. Therefore, health personnel caring for pregnant women have the responsibility to emphasize the importance of Td vaccination to avoid missed immunization opportunities.

    Few studies exist about factors affecting the outcome of horses with tetanus. 31 equids (30 horses and 1 donkey) with a clinical diagnosis of tetanus admitted to the Equine Clinic of the University of Liege between 1991 and 2006. The cases were divided into two groups according to the outcome (survivors and non-survivors). The clinical data of survivors and non-survivors were compared using an ANOVA (continuous data) or a Fisher's test (discrete data). The survival rate was 32%. Most animals were 5 years or younger, and none had been appropriately vaccinated. The non-survivors were significantly younger than the survivors. The development of dyspnoea, recumbency, and the combination of dysphagia, dyspnoea, and recumbency was observed significantly more in the non-survivors than in the survivors. The timing of tetanus antitoxin administration (either immediately after the onset of suggestive signs or after a delay) was not different between the two groups. The time between the occurrence of a wound and the first signs ranged from 2 days to 2 months and was not significantly different between groups. All non-survivors died within 8 days of the first signs. This study suggests that young animals are affected more often and more severely by tetanus than older animals. Dyspnoea, recumbency, and the combination of dysphagia, dyspnoea, and recumbency can be considered as indicators of a poor prognosis in equids suffering from tetanus.

    This study aimed to investigate serologic immunity to diphtheria and tetanus in army personnel and a sample population of adult civilians in Mashhad, Iran. Army personnel (n = 180) and civilians (n = 83) who presented at Mashhad army hospital participated in this study. Diphtheria and tetanus antitoxin levels were determined by enzyme-linked immunosorbent assay. Approximately 77% and 94% of army personnel aged 18-34 years had at least basic protection against diphtheria (antitoxin level ≥0.1 IU/mL) and tetanus (antitoxin level >0.1 IU/mL), respectively. For civilians in this age group, the proportions were 76% for both diseases. Antitoxin levels waned with age. Thus, participants older than 50 years had lower immunity; this decrease in immunity was more pronounced for tetanus than for diphtheria in both army personnel and civilians. For both diseases, geometric mean antitoxin titers and the proportion of participants with at least basic protection were higher in subjects with a history of vaccination in the last 10 years (P diphtheria and tetanus. However, the large number of susceptible older adults (>50 years old) calls for improved booster vaccination protocols.

    A total of 35 of the 59 countries that had not eliminated maternal and neonatal tetanus (MNT) as a public health problem in 1999 have since achieved the MNT-elimination goal. Neonatal tetanus deaths have decreased globally from 200,000 in 2000 to 49,000 in 2013. This is the result of increased immunization coverage with tetanus toxoid-containing vaccines among pregnant women, improved access to skilled birth attendance during delivery, and targeted campaigns with these vaccines for women of reproductive age in high-risk areas. In the process, inequities have been reduced, private-public partnerships fostered, and innovations triggered. However, lack of funding, poor accessibility to some areas, suboptimal surveillance, and a perceived low priority for the disease are among the main obstacles. To ensure MNT elimination is sustained, countries must build and maintain strong routine programs that reach people with vaccination and with clean deliveries. This should also be an opportunity to shift programs into preventing tetanus among all people. Regular assessments, and where needed appropriate action, are key to prevent increases in MNT incidence over time, especially in areas that are at higher risk. The main objective of the paper is to provide a detailed update on the progress toward MNT elimination between 1999 and 2014. It elaborates on the challenges and opportunities, and discusses how MNT elimination can be sustained and to shift the program to protect wider populations against tetanus.

    A 2-week-old Estonian Draft foal presented with signs of severe generalised tetanus, recumbency and inability to drink. The suspected source of infection was the umbilicus. Medical treatment was administered, including tetanus antitoxin, antimicrobial therapy and phenobarbital to control tetanic spasms. In addition, an intensive physiotherapy program was carried out during the recovery period. Techniques designed for syndromes involving upper motor neuron spasticity in humans were applied. Exercises aimed at weight-bearing and mobility were executed with the help of a walking-frame. The foal made a complete recovery. To our knowledge, this is the first report of the use of physiotherapy in the treatment of tetanus in horses. © 2011 The Authors.

    Recommendations for prophylactic vaccination against tetanus in horses vary greatly between countries and have scarce scientific support in the peer-reviewed literature. In human medicine, recommended booster vaccination intervals are also very variable, but are considerably longer than for horses. More information is needed about the duration of immunity induced by modern vaccines. To investigate if the duration of antibody titres previously determined to be protective against tetanus differ from what is indicated by recommended vaccination intervals for horses. Prospective seroconversion study. Thirty-four horses were enrolled for basic immunisation with an ISCOM Matrix-combination vaccine (Equilis Prequenza Te). Horses received the first vaccination at age 5-11 months, and the second dose 4 weeks later. A third vaccine dose was given 15-17 months after the second dose. Serum tetanus antibody titres were analysed by toxin-binding enzyme-linked immunosorbent assay 2 weeks as well as 14-16 months after the second dose. After the third vaccine dose, titres were checked once yearly for 3 years. Results were described by age and level of antibody titre at first sampling. Two weeks after the second dose, all horses (34/34) had antibody levels that exceeded the limit of detection, 0.04 iu/ml. After 16 months the levels were above 0.04 iu/ml in 28/33 horses, the remaining 5 horses potentially had suboptimal protection against tetanus. After the third vaccine dose antibody levels remained above 0.04 iu/ml in 25/26 horses for 1 year, 16/16 horses for 2 years, and 8/8 horses for 3 years. Horses that undergo basic immunisation with 3 doses of vaccine after age 5 months are likely to have serum antibody titres consistent with protection against tetanus for more than 3 years. Current guidelines for tetanus prophylaxis should be revised. © 2015 EVJ Ltd.

    This study aimed to estimate the evolution of the maternal and neonatal tetanus in Senegal from the tetanus vaccination coverage among pregnant women, the proportion of deliveries attended by trained medical personnel and the number of cases of tetanus declared by respective districts, helping to identify districts at high risk of neonatal tetanus (NNT). Data analysis of the epidemiological surveillance realized from 2003 to 2009 in 65 districts of Senegal. Data were collected from the reports of vaccination usage and from the Statistical Directories of the National Health Information Services of the Ministry of Health & Prevention. A district is at high risk when the incidence of NNT is ≥1 case per 1 000 Live births (LB). There were 153 reported cases of NNT in Senegal between 2003 and 2009. National incidence decreased from 0.08 to 0.03 case per 1 000 LB (p = 0,0008). The vaccination coverage of the pregnant women by at least two doses of tetanus vaccine (VAT2+) increased from 66% in 2003 to 78% in 2009. The percentage of districts that had reached a vaccination coverage ≥80% was 20% in 2003 compared to 60% in 2009 (p = 0.009). The proportion of deliveries attended by qualified medical staff evolved from 53% in 2003 to 67% in 2009 (p = 0,02). By 2009, the incidence of NNT was less than 1 case per 1,000 LBs in all districts. Assessing the elimination of maternal and neonatal tetanus in Senegal shows that progress has been made from 2003 to 2009. This was made possible through the organization of vaccination campaigns for women of childbearing age and the improvements in the conditions of deliveries.

    Background. Many adult immunization schedules recommend that tetanus and diphtheria vaccination be performed every 10 years. In light of current epidemiological trends of disease incidence and rates of vaccine-associated adverse events, the 10-year revaccination schedule has come into question. Methods. We performed cross-sectional analysis of serum antibody titers in 546 adult subjects stratified by age or sex. All serological results were converted to international units after calibration with international serum standards. Results. Approximately 97% of the population was seropositive to tetanus and diphtheria as defined by a protective serum antibody titer of ≥0.01 IU/mL. Mean antibody titers were 3.6 and 0.35 IU/mL against tetanus and diphtheria, respectively. Antibody responses to tetanus declined with an estimated half-life of 14 years (95% confidence interval, 11–17 years), whereas antibody responses to diphtheria were more long-lived and declined with an estimated half-life of 27 years (18–51 years). Mathematical models combining antibody magnitude and duration predict that 95% of the population will remain protected against tetanus and diphtheria for ≥30 years without requiring further booster vaccination. Conclusions. These studies demonstrate that durable levels of protective antitoxin immunity exist in the majority of vaccinated individuals. Together, this suggests that it may no longer be necessary to administer booster vaccinations every 10 years and that the current adult vaccination schedule for tetanus and diphtheria should be revisited.

    In course of immunizing horses with snake venoms, tetanus and diphtheria toxoids, a new serum component, T-globulin, was formed and migrated between the beta- and gamma-globulins. The T-globulin content was parallel with the antibody titre after the middle course of immunization. There were many components in snake antivenin and T-globulin was composed of most of those components. The components of diphtheria T-globulin were the same as those of crude antitoxin and tetanus T-globulin except one precipitin.

    Full Text Available Background and aim: Each analytical activity, including those carried out in Point of Care (POCT must be, at law, under the control of Laboratory Medicine. Before the implementation of the rapid tetanus quick stick (TQS test for the evaluation of the specific tetanus immunisation, a multi-disciplinary and multi-professional group was created. The aim of this study was to evaluate the ability of Emergency Department (ED staff to manage and correctly understand the result of TQS test in POCT. Materials and Methods: This analysis took into consideration 152 patients admitted to ED with traumatic wounds; information on the state of tetanus immunisation at their arrival wasn’t recorded. Blood sample analysis was performed twice. The Laboratory confirmed a 100% concordance between their results and ELISA test (standard criterion. Study design consisted of 2 phases: the first one (50 test to preliminarily evaluate if any corrective action or improvement of procedures is required, and the second one (102 tests to confirm the quality of corrective actions. Results: The concordance of results between TQS test in Laboratory and POCT test in ED was 80% in the first phase and 95% in the second one.Conclusions: The use of the rapid TQS test is a valuable tool; however, to avoid serious mistakes of interpretation, periodic checks on the quality of the results must be arranged.

    We have developed enzymoimmunoassays (EIA) for the quantitation of antibodies (Ab) to tetanus and diphtheria toxoids (TT, DT) using Immulon I plates coated with the appropriate toxoid. A preparation of human tetanus immunoglobulin with a known concentration of anti-TT Ab was used as calibrator of the anti-TT antibody assay. The assay of anti-DT Ab is calibrated with a pool of human sera whose anti-DT Ab concentration was determined by quantitative immunoelectrophoresis, using a horse anti-DT with known Ab concentration as calibrator. A peroxidase-conjugated anti-human IgG was used in both assays. ABTS was used as substrate, and the reaction was stopped after 1 min incubation with citric acid and the OD measured at 414 nm on a Vmax reader. The assays have been applied to a variety of clinical situations. In patients suspected of having tetanus, the quantitation of antibodies has been helpful in establishing a diagnosis. In patients with a history of hypersensitivity to tetanus toxoid, verification of the levels of anti-TT antibody may prevent unnecessary and potentially harmful immunizations. The assays have also been used for the diagnostic evaluation of the humoral immune response to TT and DT, both in pediatric patients and in immunosuppressed patients. Several non-responders have been detected, and we have recently used the assay to monitor the effects of fish oil administration on the humoral immune response.(ABSTRACT TRUNCATED AT 250 WORDS)

    Controversy exists about the effectiveness of vaccine-induced immune response in patients with immunoregulatory disorders. Our aim was to determine the antibody titers to diphtheria and tetanus in patients with either of two autoimmune diseases. 279 patients with SLE (205 females, aged 45.0 ± 13.8 years), 158 patients with myasthenia gravis (MG) (101 females, aged 55 ± 18.7 years) and 208 healthy subjects (122 females, aged 48 ± 14.6 years) were enrolled. Serum concentrations of diphtheria-antitoxin-IgG (A-DIPHTH) and tetanus-antitoxoid-IgG (A-TET) were determined with ELISA. Equal proportions of healthy subjects, as well as patients with SLE or MG exhibited proper antibody responses and immune protection against diphtheria and tetanus. In all three test groups, serum concentration of A-DIPHTH decreased significantly (p60-years-old) subjects. There were no significant differences among the groups in the age-related changes of A-TET and A-DIPHTH except that in diphtheria and tetanus infections in patients with SLE or MG is comparable to the healthy population.

    Demographic changes and a more active life-style in older age have contributed to an increasing public awareness of the need for lifelong vaccination. Currently many older persons have been vaccinated against selected pathogens during childhood but lack regular booster immunizations. The impact of regular vaccinations when started late in life was analyzed in an open, explorative trial by evaluating the immune response against tetanus and diphtheria in healthy older individuals. 252 persons aged above 60 years received a booster vaccination against tetanus, diphtheria, pertussis and polio and a subcohort (n=87) was recruited to receive a second booster vaccination against tetanus, diphtheria and pertussis 5 years later. The percentage of unprotected individuals at the time of enrollment differed substantially for tetanus (12%) and diphtheria (65%). Despite protective antibody concentrations 4 weeks after the first vaccination in almost all vaccinees, antibodies had again dropped below protective levels in 10% (tetanus) and 45% (diphtheria) of the cohort after 5 years. Protection was restored in almost all vaccinees after the second vaccination. No correlation between tetanus- and diphtheria-specific responses was observed, and antibody concentrations were not associated with age-related changes in the T cell repertoire, inflammatory parameters, or CMV-seropositivity suggesting that there was no general biological “non-responder type.” Post-vaccination antibody concentrations depended on pre-existing plasma cells and B cell memory as indicated by a strong positive relationship between post-vaccination antibodies and pre-vaccination antibodies as well as antibody-secreting cells. In contrast, antigen-specific T cell responses were not or only weakly associated with antibody concentrations. In conclusion, our findings demonstrate that single shot vaccinations against tetanus and/or diphtheria do not lead to long-lasting immunity in many elderly persons despite

    Enzyme-linked immunosorbent assay (ELISA), and radioimmunosorbent assay (RIST) techniques for the detection of tetanus toxin antibodies are described. Both methods proved to be highly sensitive, and allowed the measurement of 5 x 10/sup -3/ units/ml tetanus antitoxin in human serum or plasma, sensitivity and reproducibility comparing well with other techniques previously described, and being superior to haemagglutination and latex agglutination tests. Results of the two methods correlated well, and reflected the immunization histories obtained. Micro ELISA and micro RIST would seem to be suitable for the detection of immunity, or non-immunity to clinical tetanus.

    Full Text Available The medical records of ten pediatric patients with a clinical diagnosis of tetanus were reviewed retrospectively. The heart rate and blood pressure of all tetanus patients were measured noninvasively every hour during the first two weeks of hospitalization. Six of ten tetanus patients presented clinical evidence of sympathetic hyperactivity (group A and were compared with a control group consisting of four children who required mechanical ventilation for diseases other than tetanus (group B. Heart rate and blood pressure simultaneously and progressively increased to a maximum by day 7. The increase over baseline was 43.70 ± 11.77 bpm (mean ± SD for heart rate (P<0.01 and 38.60 ± 26.40 mmHg for blood pressure (P<0.01. These values were higher and significantly different from those of the control group (group B at day 6, which had an average heart rate increase over baseline of 19.35 ± 12.26 bpm (P<0.05 and blood pressure of 10.24 ± 13.30 mmHg (P<0.05. By the end of the second week of hospitalization, in group A the increase of systolic blood pressure over baseline had diminished to 9.60 ± 15.37 mmHg (P<0.05, but the heart rate continued to be elevated (27.80 ± 33.92 bpm, P = NS, when compared to day 7 maximal values. The dissociation of these two cardiovascular variables at the end of the second week of hospitalization suggests the presence of asymmetric cardiac and vascular sympathetic control. One possible explanation for these observations is a selective and delayed action of tetanus toxin on the inhibitory neurons which control sympathetic outflow to the heart.

    Tetanus, diphtheria, pertussis and measles are vaccine preventable diseases that have been reported to cause morbidity and mortality in adult population in the recent years. We aimed to document the seropositivity rates and vaccination indication for these four vaccine preventable diseases among adult and elderly patients who were seen as outpatients in a university hospital. Blood samples for tetanus, diphtheria, pertussis and measles antibodies were obtained. Results were evaluated with regards to protection levels and booster vaccine indications according to the cut-off values. A total of 1367 patients consented for the study and 1303 blood samples were available for analysis at the end of the study. The antibody levels against measles conferred protection in 98% of patients. However, 65% of the patients had no protection for diphtheria, 69% had no protection for tetanus and 90% of the patients had no protection for pertussis. Only 1.3% of the study population had seropositivity against three of the diseases-Tdap booster was indicated in 98.7%. Multivariable logistic regression showed that tetanus protection decreased with increasing age. Having a chronic disease was associated with a lower rate of protective antibodies for pertussis. We demonstrated very low rates of protection against three of the vaccine preventable diseases of childhood-diphtheria, pertussis and tetanus. Booster vaccinations are required in adult life in accordance with national and international adult vaccination guidelines. The concept of "lifelong vaccination" should be implemented and every encounter with the patient should be regarded as a chance for catch-up.

    Serologic data on diseases that are preventable by vaccine are useful to evaluate the success of immunization programs. In this study we evaluated the serologic levels of antibodies to diphtheria, tetanus, and pertussis. In a cross sectional study, a total of 360 people aged 10-25 years were randomly selected and classified by sex and age (10-14, 15-20, 21-25 years). Overall, 78.8% of people aged 10-25 years had fully protected levels of diphtheria antibody (> or = 0.1 IU/ML), and 89.7% had fully protected levels of tetanus antibody (> or = 0.1 IU/ML), 94.3% of women aged 15-25 years had anti tetanus antibody sufficient to protect against neonatal tetanus (> or = 0.1 IU/ML). Antibodies to Pertussis toxin (PT) were found in 44.2% samples but only 1.4% had fully protective levels. Antibodies to PT increased with age, ranging from 33.5% in aged 10-14 years to 54.6 % in aged 21-25 years. No differences were found between male and female, except for diphtheria in age group 21-25 years. Results of this study reveal that diphtheria and tetanus (dT) are efficient between booster doses. About pertussis, most people are susceptible to pertussis and increased PT antibodies with age suggest acquired asymptomatic Bordeella pertussis infection. Also B. pertussis infections in adolescents and adults are of concern, as they are the most important source of transmission of pertussis to young, unprotected infants. So one booster dose in adolescents and adults (as CDC recommended), to reduce mortality and morbidity in infants, is therefore suggested.

    This study aimed to determine the hospital prevalence rate of tetanus in women of childbearing age in the infectious disease department of Donka CHU in Conakry and to describe their sociodemographic characteristics and outcomes. This descriptive retrospective study examined the records of all patients aged 15 to 495 years hospitalized for tetanus over a 10-year period. During the study period, 74555 patients were hospitalized - 239 for tetanus. In all, 22 woman of childbearing age had tetanus, that is, 9.2%. Their mean age was 325 years. Most of the women were married (13/22) and lived in Conakry (18/22); 165 were housewives, and 65 patients had begun but not completed the required vaccinations. The incubation period was >75 days for 165 patients. Tetanus infection resulted from medical procedures for 9 women and trauma for 6. We recorded 125 deaths. The average duration of hospitalization was 215 days. Preventing tetanus requires a reinforcement of vaccination drives and especially the implementation of policies for booster reminders.

    Tetanus in newborns, is an under-reported public health problem and a major cause of mortality in developing countries. This study aimed to determine the predictors and outcome of tetanus in newborn infants in the slums of Bin-Qasim town, Karachi, Pakistan. We conducted a case-control study at primary health care centers of slums of Bin-Qasim town, area located adjacent to Bin Qasim seaport in Karachi, from January 2003 to December 2013. Cases were infants aged ≤30 days with tetanus, as defined by the World Health Organization. Controls were newborn infants aged ≤30 days without Tetanus, who were referred for a checkup or minor illnesses. The case to control ratio was 1:2. We analyzed 26 cases and 52 controls. The case fatality was 70.8%. We identified four independent predictors of Tetanus in newborns: maternal education (only religious education with no formal education OR 51.95; 95% CI 3.69-731), maternal non-vaccination (OR 24.55; 95% CI 1.01-131.77), lack of a skilled birth attendant (OR 44.00; 95% CI 2.30-840.99), and delivery at home (OR 11.54; 95% CI 1.01-131.77). We identified several potentially modifiable socio-demographic risk factors for Tetanus in newborns, including maternal education and immunization status, birth site, and lack of a skilled birth attendant. Prioritization of these risk factors could be useful for planning preventive and cost-effective measures.

    In a long-term neuromuscular blocked (NMB) rat preparation, tetanic stimulation of the aortic depressor nerve (ADN) enhanced the A-fiber evoked responses (ERs) in the cardiovascular region, the nucleus of the solitary tract (dmNTS). The potentiation persisted for at least several hours and may be a mechanism for adaptive adjustment of the gain of the baroreflex, with functional implications for blood pressure regulation. Using a capacitance electrode, we selectively stimulated A-fibers and acquired a stable 10-h "A-fiber only" ER baseline at the dmNTS. Following baseline, an A+C-fiber activating tetanus was applied to the ADN. The tetanus consisted of 1,000 "high current" pulses (10 trains; 300 mus, 100 Hz, 1 s), with intertrain interval of 9 s. A 10-h A-fiber only posttetanic test phase repeated the stimulus pattern of the baseline. Fourteen tetanus experiments were done in 12 rats. Compared with the baseline before tetanus, the A-fiber ER magnitudes of posttetanus hours were larger [F(13, 247) = 3.407, P ADN A+C fiber-activating tetanus produced increases in the magnitude of the A-fiber ERs in the dmNTS that persisted for several hours. In an additional rat, application of an NMDA receptor antagonist, prior to the tetanus, blocked the potentiation effect. The stimulus protocols, magnitude and duration of the effect, and pharmacology resemble associative long-term potentiation (LTP).

    The aim of this study was to investigate the diphtheria-tetanus-pertussis antibody titers after antineoplastic treatment and to suggest an appropriate vaccination approach for pediatric hemato-oncologic patients. A total of 146 children with either malignancy in remission after cessation of therapy or bone marrow failure were recruited. All children had received routine immunization including diphtheria-tetanus-acellular pertussis vaccination before diagnosis of cancer. The serologic immunity to diphtheria, tetanus and pertussis was classified as: completely protective, partially protective, or non-protective. Non-protective serum antibody titer for diphtheria, tetanus and pertussis was detected in 6.2%, 11.6%, and 62.3% of patients, respectively, and partial protective serum antibody titer for diphtheria, tetanus and pertussis was seen in 37%, 28.1%, and 8.9% of patients. There was no significant correlation between the severity of immune defect and age, gender or underlying disease. Revaccination after antineoplastic therapy showed significantly higher levels of antibody for each vaccine antigen. Our data indicates that a large proportion of children lacked protective serum concentrations of antibodies against diphtheria, tetanus, and pertussis. This suggests that reimmunization of these patients is necessary after completion of antineoplastic treatment. Also, prospective studies should be undertaken with the aim of devising a common strategy of revaccination. PMID:22219618

    Full Text Available When stationary pot culture was replaced by submerged cultivation of Clostridium tetani, an anaerobic organism, in afermentor using a vibromixer and optimum supply of sterile air to the headspace of the fermentor to flush out the accumulatedgases, a significant increase in the tetanus toxin yield in a short time cultivation (about 5 to 6 days against8 days was noticed. It was found that under optimal conditions of temperature, vibromixing, surface aeration, and analkaline pH favored toxin release. Furthermore, to enhance the production volume, fermentor culture is more suitable.The tetanus toxin was produced with good Limes flocculation (Lf titre and high antigenic purity. Under optimal conditions,the papain digest broth was successfully substituted in place of N.Z Case for the production of pure and potenttetanus toxin.

    107 patients with neonatal tetanus were studied and the value of intrathecal antitetanus serum with steroid was noted. The mortality rate in a control group (68%) was significantly higher than that of the test group (37%). Furthermore, a delay in antitetanus serum administration was found to have a strong positive linear correlation with the mortality rate. In fact, the mortality rate for neonates who were given antitetanus serum 24 hours after the onset of convulsions was found to be as high...

    Full Text Available Abstract Background Acute malaria has been associated with a decreased antibody response to tetanus and diphtheria toxoids, meningococcal, salmonella, and Hib vaccines. Interest in giving malaria drug therapy and prevention at the time of childhood immunizations has increased greatly following recent trials of intermittent preventive therapy during infancy (IPTi, stimulating this re-analysis of unpublished data. The effect of malaria chemoprophylaxis on vaccine response was studied following administration of measles vaccines and diphtheria-tetanus-whole cell pertussis (DTP vaccines. Methods In 1975, six villages divided into two groups of children ≤74 months of age from Burkina Faso, were assigned to receive amodiaquine hydrochloride chemoprophylaxis (CH+ every two weeks for seven months or no chemoprophylaxis (CH-. After five months, children in each group received either one dose of measles or two doses of DTP vaccines. Results For recipients of the measles vaccine, the seroconversion rates in CH+ and CH- children, respectively, were 93% and 96% (P > 0.05. The seroresponse rates in CH+ and CH- children respectively, were 73% and 86% for diphtheria (P > 0.05 and 77% and 91% for tetanus toxoid (P > 0.05. In a subset analysis, in which only children who strictly adhered to chemoprophylaxis criteria were included, there were, likewise, no significant differences in seroconversion or seroresponse for measles, diphtheria, or tetanus vaccines (P > 0.05. While analysis for pertussis showed a 43% (CH+ and 67% (CH- response (P Conclusion Malaria chemoprophylaxis prior to vaccination in malaria endemic settings did not improve or impair immunogenicity of DTP and measles vaccines. This is the first human study to look at the association between malaria chemoprophylaxis and the serologic response to whole-cell pertussis vaccine.

    Full Text Available Aim: At the aim of this study was to determine the tetanus seroprevalence among pregnant women and childbearing aged woman living in the Ben-u Sen Health Center region that is in lower socio-economical level. Materials and methods: In this descriptive study, a team including the staff of health center and several volunteers visited the houses of pregnant women living in the health center coverage region and questionnaires were completed through face to face interviews. The study group included 214 pregnant women. Among them, serum samples of 197 subjects’ were studied for anti-toxic antibody for tetanus. For control, serum samples from 200 women living in the same health center region were collected. It was evaluated as partially protective, protective and longterm protection when tetanus antibody level was 0,01-<0,1 IU/ml, 0,1-<1.0 IU/ml and 1,0 IU/ml and over, respectively. Results: The mean age of the women was 26,4, mean marriage and first pregnancy ages were 17,9 and 18,9, respectively, and 40% of the subjects had never been examined or received follow up by a health center. It was revealed that 25.8% of the subjects were not protected and 74.2% had a full protection level of antibody. Within the control group, the same levels of antibodies were detected in 40.0% and 60.0% of the women, respectively. Conclusion: The study indicates that the immunity levels against tetanus are not satisfactory and every childbearing aged woman should be included in a vaccination program whenever they receive any examination in a health center.

    Conclusion: It is essential to begin campaigns or integrate complete maternal tetanus toxoid immunization at primary health centers (PHC during antenatal care. Immunization needs to be arranged so pregnant women can be educated regarding the importance of ANC and the risks of unhygienic home delivery, and immunization should be addressed with adequate information. Pregnant women and those of childbearing age in mountainous areas should be the first targets for these activities.

    In 20 dogs and I cat a diagnosis of tetanus was made based on the typical clinical signs and a possible wound history. In 7 animals a tooth abnormality was considered as the entrance way of the bacteria. By means of radiography of the thorax several animals were evaluated for the presence of possible complications such as aspiration pneumonia, megaoesophagus or hiatal hernia. The treatment existed mainly of metronidazole as an antibiotic, acetylpromazine to control the muscle spasms and addit...

    The case records of 20 horses with tetanus referred to the Ontario Veterinary College-Veterinary Teaching Hospital between 1970 and 1990 were reviewed. The fatality rate was 75%. There was a strong association with previous vaccination and survival (P = .03). Most of the animals had been injured an average of 9 days (range 2 to 21 days) prior to development of clinical signs. Hyperesthesia and prolapse of the third eyelid were the most common clinical signs. Treatment regimens varied during hospitalization; however, all horses received parenteral penicillin, tranquilizers, tetanus toxoid, and antitoxin. Five of the nonsurviving animals were given intrathecal tetanus antitoxin. One animal had seizures as a complication of intrathecal treatment. The prognosis was best for horses that (1) had been vaccinated prior to the injury, (2) responded to the phenothiazine tranquilizers, and (3) did not rapidly (over 24 to 48 hours) become recumbent. Considering the species susceptibility, potential for contaminated wounds, and the increased survival of vaccinated horses, yearly revaccination is recommended.

    Successful active immunisation of horses against tetanus is dependent on a number of factors of which the toxoid preparation used, its method of application and the ability of the individual horse to respond are fundamental. Two immunisation schedules using an aluminium-based toxoid preparation were examined and the protection determined by monitoring the level of antitoxin afforded by each schedule. The results obtained demonstrated that 2 doses of this toxoid are necessary to ensure 12 months protection in all horses. These results are discussed in relation to the factors involved in active immunisation against tetanus. Reference is also made to the occurrence of a transient phase of reduced levels of antitoxin following booster doses of toxoid in immunised horses during which it is considered these horses could become more susceptible to tetanus. The effect of a booster dose on immunised horses was examined and while there can be a reduction in the level of antitoxin in some immunised horses following this dose its effect is minimal, short-lived and for all practical purposes can be disregarded. The application of the booster dose in practice is also discussed.

    An international collaborative study to validate 2 alternative in vitro methods for the potency testing of human tetanus immunoglobulin products was organised by the European Directorate for the Quality of Medicines & HealthCare (EDQM). The study, run in the framework of the Biological Standardisation Programme (BSP) under the aegis of the European Commission and the Council of Europe, involved 21 official medicines control and industry laboratories from 15 countries. Both methods, an enzyme-linked immunoassay (EIA) and a toxoid inhibition assay (TIA), showed good reproducibility, repeatability and precision. EIA and TIA discriminated between low, medium and high potency samples. Potency estimates correlated well and both values were in close agreement with those obtained by in vivo methods. Moreover, these alternative methods allowed to resolve discrepant results between laboratories that were due to product potency loss and reporting errors. The study demonstrated that EIA and TIA are suitable quality control methods for tetanus immunoglobulin, which can be standardised in a control laboratory using a quality assurance system. Consequently, the Group of Experts on Human Blood and Blood Products of the European Pharmacopoeia revised the monograph on human tetanus immunoglobulins to include both the methods as compendial alternatives to the in vivo mouse challenge assay. 2010 The International Association for Biologicals.

    Current management guidelines of HIV infected adults include recommendation to immunization against common vaccine preventable diseases. This effort is hindered by the scarce knowledge regarding the immunization status of this especially vulnerable patient group. This study analyzed the serostatus for pertussis, diphtheria and tetanus of more than 700 HIV infected individuals residing in Austria. These individuals were representative for the Austrian HIV cohort regarding sex, age, transmission risk and HIV progression markers. Overall, 73.6% were on suppressive HAART, mean CD4 cell count was 603c/μl. Seropositivity was 84% for diphtheria, 51% for tetanus and 1% for pertussis. Migrants had a lower chance of tetanus seropositivity (OR 0.30 (CI 0.21 to 0.43)). Increase in CDC classification were associated with increased diphtheria seropositivity (OR 1.42 (CI 1.02 to 1.98)) and a CD4 nadir200c/μl, 95% lacked seroprotection to at least one of the antigens included in the triple vaccine Tdap and could be vaccinated. Thus, a proactive approach would largely reduce the number of patients at risk for these vaccine-preventable diseases. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Lung transplant (LuTx) patients are routinely immunized against tetanus and diphtheria. However, few studies have been done to measure serologic immunity in the transplant population. The primary objective of this study was to compare tetanus and diphtheria antibody concentrations in LuTx vs. healthy subjects. Serum was used from an available sample of 111 total individuals (n = 36 healthy; n = 75 LuTx). Tetanus and diphtheria antibody concentrations were measured using an enzyme-linked immunosorbant assay method. A statistically significant difference in both tetanus and diphtheria antibody concentrations was found between the groups. The median concentration of tetanus antibody was higher for healthy individuals compared with the LuTx group (3.2 IU/mL [1.2-5.2 interquartile range {IQR}] vs. 1.3 IU/mL [0.4-2.6 IQR], respectively; P = 0.0001). No difference in time was found since the last tetanus-diphtheria vaccine or tetanus-diphtheria-pertussis vaccine dose between the groups (healthy 76.5 months [16-114 IQR] vs. LuTx 74.5 months [45-118 IQR]; P = 0.44). Tetanus and diphtheria immunizations are recommended for LuTx patients to reduce the risk of infection. Because the LuTx group has lower antibody concentrations, further studies should investigate the possible need for more frequent tetanus and diphtheria boosters. © 2014 John Wiley & Sons A/S.

    Tajikistan had a major diphtheria outbreak (≈ 10,000 cases) in the 1990 s, which was controlled after nationwide immunization campaigns with diphtheria-tetanus toxoid in 1995 and 1996. Since 2000, only 52 diphtheria cases have been reported. However, in coverage surveys conducted in 2000 and 2005, diphtheria-tetanus-pertussis vaccine coverage was lower than administratively reported estimates raising concerns about potential immunity gaps. To further assess population immunity to diphtheria in Tajikistan, diphtheria antibody testing was included in a large-scale nationwide serosurvey for vaccine-preventable diseases conducted in connection with a poliomyelitis outbreak in 2010. In addition, the serosurvey provided an opportunity to assess population immunity to tetanus. Residents of all regions of Tajikistan aged 1-24 years were included in the serosurvey implemented during September-October 2010. Participants were selected through stratified cluster sampling. Specimens were tested for diphtheria antibodies using a Vero cell neutralization assay and for tetanus antibodies using an anti-tetanus IgG ELISA. Antibody concentrations ≥ 0.1 IU/mL were considered seropositive. Overall, 51.4% (95% CI, 47.1%-55.6%) of participants were seropositive for diphtheria and 78.9% (95% CI, 74.7%-82.5%) were seropositive for tetanus. The lowest percentages of seropositivity for both diseases were observed among persons aged 10-19 years: diphtheria seropositivity was 37.1% (95% CI, 31.0%-43.7%) among 10-14 year-olds, and 35.3% (95% CI, 29.9%-41.1%) among 15-19 year-olds; tetanus seropositivity in respective age groups was 65.3% (95% CI, 58.4%-71.6%) and 70.1% (95% CI, 64.5%-75.2%). Population immunity for diphtheria in Tajikistan is low, particularly among 10-19 year-olds. Population immunity to tetanus is generally higher than for diphtheria, but is suboptimal among 10-19 year-olds. These findings highlight the need to improve routine immunization service delivery, and support a

    To evaluate pediatric intensive care unit (PICU) needs, outcome and predictors of mortality in post-neonatal tetanus. Review of 30 consecutive post-neonatal tetanus cases aged 1 months to 12 years admitted to a PICU in north India over a period of 10 years (January 2006 to December 2015). Chronic suppurative otitis media was the commonest portal of entry. All received tetanus toxoid, human tetanus immunoglobulin (HTIG) and appropriate antibiotics; 7 (23.3%) received intrathecal HTIG. Common complications were respiratory failure, rhabdomyolysis, autonomic dysfunction, acute kidney injury and healthcare-associated infections. PICU needs were as follows: ventilation; benzodiazepine, morphine and magnesium sulfate infusion; neuromuscular blockers, inotropes, tracheostomy and renal replacement therapy. Mortality rate was 40%; severity Grade IIIb, autonomic dysfunction, use of vasoactive drugs and those who did not receive intrathecal HTIG were significantly associated with mortality. Post-neonatal tetanus is associated with high mortality, and PICU needs include management of spasms, autonomic dysfunction and complications and cardiorespiratory support. © The Author [2017].

    Tetanus was a major cause of mortality in the free-ranging population of rhesus monkeys on Cayo Santiago prior to 1985 when the entire colony was given its first dose of tetanus toxoid. The immediate reduction in mortality that followed tetanus toxoid inoculation (TTI) has been documented, but the long-term demographic effects of eliminating tetanus infections have not. This study uses the Cayo Santiago demographic database to construct comparative life tables 12 years before, and 12 years after, TTI. Life tables and matrix projection models are used to test for differences in: (i) survival among all individuals as well as among social groups, (ii) long-term fitness of the population, (iii) age distribution, (iv) reproductive value, and (v) life expectancy. A retrospective life table response experiment (LTRE) was performed to determine which life cycle transition contributed most to observed changes in long-term fitness of the population post-TTI. Elimination of clinical tetanus infections through mass inoculation improved the health and well-being of the monkeys. It also profoundly affected the population by increasing survivorship and long-term fitness, decreasing the differences in survival rates among social groups, shifting the population's age distribution towards older individuals, and increasing reproductive value and life expectancy. These findings are significant because they demonstrate the long-term effects of eradicating a major cause of mortality at a single point in time on survival, reproduction, and overall demography of a naturalistic population of primates. © 2014 Wiley Periodicals, Inc.

    Patients with antibody deficiencies depend on the presence of a variety of antibody specificities in intravenous immunoglobulin (IVIG) to ensure continued protection against pathogens. Few studies have examined levels of antibodies to specific pathogens in IVIG preparations and little is known about the specific antibody levels in patients under regular IVIG treatment. The current study determined the range of antibodies to tetanus, diphtheria, measles and varicella in IVIG products and the levels of these antibodies in patients undergoing IVIG treatment. We selected 21 patients with primary antibody deficiencies who were receiving regular therapy with IVIG. Over a period of one year, we collected four blood samples from each patient (every 3 months), immediately before immunoglobulin infusion. We also collected samples from the IVIG preparation the patients received the month prior to blood collection. Antibody levels to tetanus, diphtheria, measles and varicella virus were measured in plasma and IVIG samples. Total IgG levels were determined in plasma samples. Antibody levels to tetanus, diphtheria, varicella virus and measles showed considerable variation in different IVIG lots, but they were similar when compared between commercial preparations. All patients presented with protective levels of antibodies specific for tetanus, measles and varicella. Some patients had suboptimal diphtheria antibody levels. There was a significant correlation between serum and IVIG antibodies to all pathogens, except tetanus. There was a significant correlation between diphtheria and varicella antibodies with total IgG levels, but there was no significant correlation with antibodies to tetanus or measles. The study confirmed the variation in specific antibody levels between batches of the same brand of IVIG. Apart from the most common infections to which these patients are susceptible, health care providers must be aware of other vaccine preventable diseases, which still exist

    Become almost non-existent in the developed countries, the hospital-borne tetanus always stays of current events in our country in spite of the forensic problem which it puts. The objectives of this study were to determine prevalence of this affection, to describe its clinical picture and to determine its lethality. It is about a retrospective study of a duration of 11 years realized in the service of the infectious diseases of Conakry. Among 8649 hospitalizations from 2001 till 2012 we brought together 239 cases of tetanus (2.7%) among which 60 hospital-borne tetanus (0.7%). Men represented 73% of these cases, with a sex-ratio M/F of 2.7. The age bracket of 20-40 years was the most affected with 32 cases (53.3%). A single patient had begun his vaccinal calendar which had remained incomplete. Both national hospitals of the CHU of Conakry and private hospitals were the biggest suppliers of this hospital-borne tetanus with respectively 22 and 27 cases (36.6 and 45%). Tetanus related to IM of quinine represented 26 cases (43.3%) whereas the hernial cure was found in 16 cases (26.6%). The average duration of invasion and incubation was respectively 1.5 days and 6 days for the dead (n = 45.7%) and 2 days and 10.5 days for the survivors. Three-quarters of 60 patients died. The fight against this type of tetanus passes inevitably by an improvement of the working conditions, a strict application of the rules of asepsis and the in-service training of the medical and paramedical staff.

    It has been reported that equine peripheral blood mononuclear cells (PBMNs) do not proliferate in response to tetanus toxoid (TT) (Frayne and Stokes 1995, Research in Veterinary Science 59, 79-81). Here we demonstrate that lymphocyte proliferation responses to TT, which are characteristic of a recall antigen, may be achieved under certain culture conditions. Given that TT vaccination is routinely applied to many horses, TT is a suitable antigen for the investigation of cellular immune responses by peripheral blood mononuclear cells in the horse.

    A dot immunoassay for simultaneous semiquantitative detection of IgG against tetanus toxoid (Ttx) and diphtheria toxoid (Dtx) and qualitative detection of anti-Bordetella pertussis IgGs in human blood serum using carbon nanoparticles functionalized with streptococcal protein G was developed. Inactivated B. pertussis cells in suspension form were used as an antigen in the immunoassay. Pertussis, tetanus, and diphtheria antigens were separately spotted onto nitrocellulose strips, and then the immunostrips were successively incubated with blood sera and a suspension of carbon nanoparticles. The immunostrips were then scanned with a flatbed scanner, and the images obtained were processed with ImageJ. One hundred fifty-five venous blood serum samples from children vaccinated with diphtheria, tetanus, and whole-cell pertussis (DTwP) vaccine were tested in comparison with a conventional ELISA and agglutination test. The total time required for analysis of 32 serum samples was less than 3 h. Comparison between the results of the dot immunoassay and the corresponding ELISA/agglutination test revealed a high level of agreement (Cohen's kappa between 0.765 and 0.813). The lower limit of quantification was 0.06 IU/ml for anti-Ttx and anti-Dtx. The intra-assay coefficients of variation were less than 15% for anti-Ttx and anti-Dtx and less than 10% for anti-pertussis. The diagnostic sensitivity of detection of the antibody protection level was 93.5% for anti-Ttx [95% confidence interval (CI) 83.5-97.9%], 92.4% for anti-Dtx (95% CI 80.9297.5%), and 90.2% for anti-pertussis (95% CI 75.9-96.8%). The diagnostic specificity was 90.9% for anti-Ttx (95% CI 57.1-99.5%), 85% for anti-Dtx (95% CI 61.1-96.0%), and 89.3% for anti-pertussis (95%CI 80.8-94.5%). The dot immunoassay developed does not require expensive reading equipment, and allows detection of antibodies against three antigens in a single analysis. The immunostrips can be stored for a long time without changes in the

    Diphtheria, pertussis, and tetanus are potentially deadly bacterial infections that are largely preventable through vaccination, though they remain in the population. This issue reviews the epidemiology, pathophysiology, diagnosis, and current recommended emergency management of these conditions. Disease-specific medications, as well as treatment of the secondary complications, are examined in light of the best current evidence. Resources include obtaining diphtheria antitoxin from the United States Centers for Disease Control and Prevention and best-practice recommendations with regard to testing, involvement of government health agencies, isolation of the patient, and identification and treatment of close contacts. Most importantly, issues regarding vaccination and prevention are highlighted.

    The heavy chains of both botulinum neurotoxin type B and tetanus toxin form channels in planar bilayer membranes. These channels have pH-dependent and voltage-dependent properties that are remarkably similar to those previously described for diphtheria toxin. Selectivity experiments with anions and cations show that the channels formed by the heavy chains of all three toxins are large; thus, these channels could serve as ``tunnel proteins'' for translocation of active peptide fragments. These findings support the hypothesis that the active fragments of botulinum neurotoxin and tetanus toxin, like that of diphtheria toxin, are translocated across the membranes of acidic vesicles.

    Vaccination effectiveness is proven when the disease does not develop after a patient is exposed to the pathogen. In the case of rare diseases, vaccination effectiveness is assessed by monitoring specific antibody levels in the population. Such recurrent analyses allow the evaluation of vaccination programs. The primary schedule of diphtheria and tetanus vaccinations is similar in various countries, with differences mainly in the number and timing of booster doses. The aim of the study was to assess diphtheria and tetanus antibody concentrations in a population of healthy children.Diphtheria and tetanus antibody levels were analyzed in a group of 324 children aged 18 to 180 months. All children were vaccinated in accordance with the Polish vaccination schedule.Specific antibody concentrations greater than 0.1 IU/mL were considered protective against tetanus or diphtheria. Levels above 1.0 were considered to ensure long-term protection.Protective levels of diphtheria antibodies were found in 229 patients (70.46%), and of tetanus in 306 patients (94.15%). Statistically significant differences were found in tetanus antibody levels in different age groups. Mean concentrations and the percentage of children with high tetanus antibody titers increased with age. No similar correlation was found for diphtheria antibodies. High diphtheria antibody levels co-occurred in 72% of the children with high tetanus antibody levels; 95% of the children with low tetanus antibody levels had low levels of diphtheria antibodies.The percentage of children with protective diphtheria antibody levels is lower than that in the case of tetanus antibodies, both in Poland and abroad, but the high proportion of children without diphtheria protection in Poland is an exception. This is all the more puzzling when taking into account that Polish children are administered a total of 5 doses containing a high concentration of diphtheria toxoid, at intervals shorter than 5 years.

    Tetanus and botulinum neurotoxins are produced by anaerobic bacteria of the genus Clostridium and are the most poisonous toxins known, with 50% mouse lethal dose comprised within the range of 0.1-few nanograms per Kg, depending on the individual toxin. Botulinum neurotoxins are similarly toxic to humans and can therefore be considered for potential use in bioterrorism. At the same time, their neurospecificity and reversibility of action make them excellent therapeutics for a growing and heterogeneous number of human diseases that are characterized by a hyperactivity of peripheral nerve terminals. The complete crystallographic structure is available for some botulinum toxins, and reveals that they consist of four domains functionally related to the four steps of their mechanism of neuron intoxication: 1) binding to specific receptors of the presynaptic membrane; 2) internalization via endocytic vesicles; 3) translocation across the membrane of endocytic vesicles into the neuronal cytosol; 4) catalytic activity of the enzymatic moiety directed towards the SNARE proteins. Despite the many advances in understanding the structure-mechanism relationship of tetanus and botulinum neurotoxins, the molecular events involved in the translocation step have been only partially elucidated. Here we will review recent advances that have provided relevant insights on the process and discuss possible models that can be experimentally tested.

    Hurdle negative binomial model regression is a method that can be used for discreate dependent variable, excess zero and under- and overdispersion. It uses two parts approach. The first part estimates zero elements from dependent variable is zero hurdle model and the second part estimates not zero elements (non-negative integer) from dependent variable is called truncated negative binomial models. The discrete dependent variable in such cases is censored for some values. The type of censor that will be studied in this research is right censored. This study aims to obtain the parameter estimator hurdle negative binomial regression for right censored dependent variable. In the assessment of parameter estimation methods used Maximum Likelihood Estimator (MLE). Hurdle negative binomial model regression for right censored dependent variable is applied on the number of neonatorum tetanus cases in Indonesia. The type data is count data which contains zero values in some observations and other variety value. This study also aims to obtain the parameter estimator and test statistic censored hurdle negative binomial model. Based on the regression results, the factors that influence neonatorum tetanus case in Indonesia is the percentage of baby health care coverage and neonatal visits.

    The aim of this study was to describe the epidemiological, clinical, and prognostic aspects of tetanus associated with road accidents and to make recommendations. This observational study collected retrospective clinical data over a 9-year period about adults admitted for trismus and/or generalized or localized paroxysm after a road accident. The study included 25 patients, accounting for 22.12 % of all tetanus cases. Men were massively overrepresented (sex-ratio M/F: 24/1). The median age was 34 ± 8 years. In all, vaccination status was unknown for 4 patients and known to be negative for 21. Immunoprophylaxis was nonexistent in all cases. The generalized clinical form was dominant (96 %). Severity reached level III for 12 % of patients. The points of entry included open leg fractures (4 cases), head wounds (2), mucocutaneous wounds (14), and muscle contusions (5). The mean time to referral for tetanus was 8 ± 7 days, and the median hospital stay 9.08 ± 11 days. Patients were mostly residents of urban (56 %) and suburban areas (28 %) [P = 0.04]. Two cases were complicated by severe malaria. The mortality rate was 60 %, and 52 % of the deaths occurred within the first 72 hours after hospitalization. It is essential to promote serum therapy and tetanus immunization for patients after road accidents. Increasing the awareness of traditional healers of these treatments deserves consideration.

    Tetanus is a life threatening preventable infection relatively uncommon in the developed world but occurs frequently in developing countries with case fatality rate of 40-60%. We conducted the study as there is no recent review regarding adult tetanus in Ethiopia which looked at the predisposing factors, presenting features and case fatality rate. The study aims to evaluate clinical characteristics of adult tetanus as related to predisposing factors, presenting features and treatment outcome. This is a retrospective review of adult tetanus cases admitted to medical ward of Gondar University Hospital, North West Ethiopia, over a period of 5-years. A total of 29 adults were admitted with the diagnosis of generalized tetanus during the study period. There were more male then female patients (sex ratio 1.9:1) with rural dwellers constituting the majority. The mean age of patients was 35 +/- 14 yrs (range, 18-70 yrs. Majority of patients (72.4%) sustained acute injury preceding symptom onset, often on lower extremity. Three rural mothers, who denied history of trauma, developed puerperal tetanus with in 2 weeks of delivery, genital tract thought to be the portal of entry. Almost all patients, who had sustained acute injury, did not seek medical help for their wounds and missed the chance to receive prophylaxis for tetanus. Over all, 48.3% had severe, 37.9% moderate, and 13.8% mild form of tetanus at presentation. The most common clinical presentation was trismus (100%), followed by stiff neck and back (93.1%) and neck rigidity (86.2).Over all mortality rate was 41.4%. Respiratory failure requiring ventilatory support (66.7%) was the major cause of death. The study recommends a need for tetanus immunization in those who had acute injury and planning to educate individuals at risk to recognise symptoms early, and seek medical care to combat this fatal disease.

    To describe clinical data of hospitalized adult equids and foals with tetanus. Multicenter retrospective study (2000-2014). Twenty Western, Northern, and Central European university teaching hospitals and private referral centers. One hundred fifty-five adult equids (>6 months) and 21 foals (tetanus. None. Information on geographic, annual and seasonal data, demographic- and management-related data, clinical history, clinical examination and blood analysis on admission, complications, treatments, and outcomes were described and statistically compared between adults and foals. The described cases were often young horses. In 4 adult horses, tetanus developed despite appropriate vaccination and in 2 foals despite preventive tetanus antitoxin administration at birth. Castration, hoof abscesses, and wounds were the most common entry sites for adults; umbilical cord infections and wounds for foals. Stiffness was the commonest observed initial clinical sign. Blood analyses frequently revealed an inflammatory response, hemoconcentration, muscle damage, azotemia, negative energy balance, liver damage, and electrolyte and acid base disturbances. Common complications or clinical signs developing during hospitalization included dysphagia, dyspnea, recumbency, hyperthermia, seizures, hyperlipemia, gastrointestinal impactions, dysuria, and laryngeal spasms. Cases were supported with wound debridement, antimicrobial treatment, tetanus antitoxin, muscle spasm and seizure control, analgesia, anti-inflammatory drugs, fluid therapy, and nutritional support. Mortality rates were 68.4% in adult horses and 66.7% in foals. Foals differed from adult horses with respect to months of occurrence, signalment, management-related data, potential causative events, clinical signs on admission, blood analysis, complications, and severity grades. This is the first study that rigorously describes a large population of equids affected by tetanus. The information provided is potentially useful to

    Full Text Available A method for the screening of tetanus and diphtheria antibodies in serum using anatoxin (inactivated toxin instead of toxin was developed as an alternative to the in vivo toxin neutralization assay based on the toxin-binding inhibition test (TOBI test. In this study, the serum titers (values between 1.0 and 19.5 IU measured by a modified TOBI test (Modi-TOBI test and toxin neutralization assays were correlated (P < 0.0001. Titers of tetanus or diphtheria antibodies were evaluated in serum samples from guinea pigs immunized with tetanus toxoid, diphtheria-tetanus or triple vaccine. For the Modi-TOBI test, after blocking the microtiter plates, standard tetanus or diphtheria antitoxin and different concentrations of guinea pig sera were incubated with the respective anatoxin. Twelve hours later, these samples were transferred to a plate previously coated with tetanus or diphtheria antitoxin to bind the remaining anatoxin. The anatoxin was then detected using a peroxidase-labeled tetanus or diphtheria antitoxin. Serum titers were calculated using a linear regression plot of the results for the corresponding standard antitoxin. For the toxin neutralization assay, L+/10/50 doses of either toxin combined with different concentrations of serum samples were inoculated into mice for anti-tetanus detection, or in guinea pigs for anti-diphtheria detection. Both assays were suitable for determining wide ranges of antitoxin levels. The linear regression plots showed high correlation coefficients for tetanus (r² = 0.95, P < 0.0001 and for diphtheria (r² = 0.93, P < 0.0001 between the in vitro and the in vivo assays. The standardized method is appropriate for evaluating titers of neutralizing antibodies, thus permitting the in vitro control of serum antitoxin levels.

    In view of waning antitoxin titres over time after the last vaccine dose against diphtheria and tetanus, we determined the immunity levels in adults to identify most susceptible groups for protection in Singapore. Our study involved residual sera from 3293 adults aged 18-79 who had participated in a national health survey in 2010. IgG antibody levels were determined using commercial enzyme-linked immunosorbent assay. Overall, 92.0% (95% confidence interval [CI]: 91.1-92.9%) had at least basic protection against diphtheria (antibody levels ≥0.01 IU/ml), while 71.4% (95% CI: 69.8-72.9%) had at least short-term protection against tetanus (antibody levels >0.1 IU/ml). The seroprevalence declined significantly with age for both diseases; the drop was most marked in the 50- to 59-year age group for diphtheria and 60- to 69-year age group for tetanus. There was a significant difference in seroprevalence by residency for diphtheria (92.8% among Singapore citizens versus 87.1% among permanent residents; P = 0.001). The seroprevalence for tetanus was significantly higher among males (83.2%) than females (62.4%) (P < 0.0005). It may be of value to consider additional vaccination efforts to protect older adults at higher risk for exposure against diphtheria and tetanus, particularly those travelling to areas where diphtheria is endemic or epidemic. © The Author 2015.

    Oligoclonal combinations of several monoclonal antibodies (MAbs) are being considered for the treatment of various infectious pathologies. These combinations are less sensitive to antigen structural changes than individual MAbs; at the same time, their characteristics can be more efficiently controlled than those of polyclonal antibodies. The main goal of this study was to evaluate the binding characteristics of six biclonal equimolar preparations (BEP) of tetanus toxin (TeNT)-specific MAbs and to investigate how the MAb combination influences the BEPs' protective capacity. We show that a combination of TeNT-specific MAbs, which not only bind TeNT but also exert positive cooperative effects, results in a BEP with superior binding characteristics and protective capacity, when compared with the individual component MAbs. Furthermore, we show that a MAb with only partial protective capacity but positive effects on the binding of the other BEP component can be used as a valuable constituent of the BEP.

    The immunogenicity and safety of one dose of Tdap-IPV (tetanus, diphtheria, acellular pertussis and inactivated poliomyelitis vaccine) and two doses of Td-IPV (tetanus, diphtheria and inactivated poliomyelitis vaccine) were assessed in adults who had not received a diphtheria- and tetanus-containing vaccine in the last 20 years. This open-label, multicentre study was conducted in adults aged ≥ 40 years with no diphtheria- and tetanus-containing vaccine in the last 20 years. Participants received one dose of Tdap-IPV followed by two doses of Td-IPV (0, 1, 6 month schedule). Primary immunogenicity objectives: to demonstrate acceptable seroprotection rates (percentage of participants with antibody titre above threshold) post-dose 3 for diphtheria (≥ 0.1IU/mL by seroneutralization assay [SNA]); tetanus (≥ 0.1IU/mL by enzyme-linked immunosorbent assay [ELISA]); and poliomyelitis (≥ 8 1/dil by SNA); and to evaluate the percentage of participants with an antibody concentration ≥ 5EU/mL (by ELISA) for pertussis antigens post-dose 1. Seroprotection rates were acceptable if the lower limit of the 95% confidence interval (CI) was >95%. Percentage of participants with basic clinical immunity against diphtheria (≥ 0.01IU/mL) was also assessed. Safety (adverse events [AEs] and serious AEs) was assessed after each dose. Overall, 336 participants were included (mean age: 60.2 years). Post-dose 3 seroprotection rates were: diphtheria, 94.6% (CI 91.5-96.8); tetanus and poliomyelitis, 100% (CI: 98.8-100). Percentage of participants with an antibody titre ≥ 5EU/mL against pertussis antigens was ≥ 95.8% for all five pertussis components. Basic clinical immunity against diphtheria was achieved in 100% (CI: 98.8-100) of participants. AEs were reported more frequently following vaccination with Tdap-IPV (post-dose 1: 65.3%) than with Td-IPV (post-dose 2: 48.3%; post-dose 3: 50.3%). This study highlights the benefits of using Tdap-IPV followed by two doses of Td-IPV in an

    Recent studies suggest that exposure to perfluorinated alkylate substances (PFASs) may induce immunosuppression in humans and animal models. In this exploratory study, 12 healthy adult volunteers were recruited. With each subject, serum-PFAS concentrations were measured and their antibody responses...... prospectively followed for 30 days after a booster vaccination with diphtheria and tetanus. The results indicated that serum-PFAS concentrations were positively correlated and positively associated with age and male sex. The specific antibody concentrations in serum were increased from Day 4 to Day 10 post......-booster, after which a constant concentration was reached. Serum PFAS concentrations showed significant negative associations with the rate of increase in the antibody responses. Interestingly, this effect was particularly strong for the longer-chain PFASs. All significant associations remained significant after...

    Diphtheria, pertussis, and tetanus are potentially deadly bacterial infections that are largely preventable through vaccination, though they remain in the population. This issue reviews the epidemiology, pathophysiology, diagnosis, and current recommended emergency management of these conditions. Disease-specific medications, as well as treatment of the secondary complications, are examined in light of the best current evidence. Resources include obtaining diphtheria antitoxin from the United States Centers for Disease Control and Prevention and best-practice recommendations with regard to testing, involvement of government health agencies, isolation of the patient, and identification and treatment of close contacts. Most importantly, issues regarding vaccination and prevention are highlighted. [Points & Pearls is a digest of Pediatric Emergency Medicine Practice].

    Full Text Available Neonatal Tetanus (NT is a preventable cause of mortality and neurological sequelae that occurs at higher incidence in resource-poor countries, presumably because of low maternal immunisation rates and unhygienic cord care practices. We aimed to determine changes in the incidence of NT, characterize and investigate the associated risk factors and mortality in a prospective cohort study including all admissions over a 15-year period at a County hospital on the Kenyan coast, a region with relatively high historical NT rates within Kenya.We assessed all neonatal admissions to Kilifi County Hospital in Kenya (1999-2013 and identified cases of NT (standard clinical case definition admitted during this time. Poisson regression was used to examine change in incidence of NT using accurate denominator data from an area of active demographic surveillance. Logistic regression was used to investigate the risk factors for NT and factors associated with mortality in NT amongst neonatal admissions. A subset of sera from mothers (n = 61 and neonates (n = 47 were tested for anti-tetanus antibodies.There were 191 NT admissions, of whom 187 (98% were home deliveries. Incidence of NT declined significantly (Incidence Rate Ratio: 0.85 (95% Confidence interval 0.81-0.89, P<0.001 but the case fatality (62% did not change over the study period (P = 0.536. Younger infant age at admission (P = 0.001 was the only independent predictor of mortality. Compared to neonatal hospital admittee controls, the proportion of home births was higher among the cases. Sera tested for antitetanus antibodies showed most mothers (50/61, 82% had undetectable levels of antitetanus antibodies, and most (8/9, 89% mothers with detectable antibodies had a neonate without protective levels.Incidence of NT in Kilifi County has significantly reduced, with reductions following immunisation campaigns. Our results suggest immunisation efforts are effective if sustained and efforts should continue to

    2018-04-01

    Full Text Available Background: Bordetella pertussis or whooping cough is a serious and vaccine-preventable illness. Despite widespread vaccination in the pediatric population, pertussis still infects approximately 100,000 infants each year in the United States. The purpose of this study was to determine gaps in pharmacists’ understanding, attitudes, practices, and barriers surrounding the tetanus, diphtheria, and pertussis (Tdap vaccination recommendation for patients who are pregnant or planning to come in close contact with infants. Methods: This study was a descriptive, exploratory electronic survey. The survey assessed three major areas; the role of the pharmacist in Tdap vaccination, perceived barriers to vaccination, and understanding the recommendations. Results: A total of 225 pharmacists responded to the survey. Pharmacists who responded to this survey agreed that pharmacists should have a role vaccinating the public and individuals expecting to come into contact with a newborn, (88.5% and 86.9% respectively, but fewer agreed that pharmacists should have a role vaccinating pregnant women against tetanus, diphtheria, and pertussis (77%, p < 0.001. Based on the responses to case scenarios, only 22.5% and 30.6% of respondents understood the recommendations. Numerous barriers to vaccinating pregnant women were identified. Conclusion: While most pharmacists surveyed felt they should have a role in vaccinating pregnant women and those expecting to come in contact with a newborn, there are barriers to implementing this practice. Future efforts should focus on further evaluating identified gaps and developing programs for pharmacists that emphasize the significance of vaccinating these patients to reduce the burden of pertussis in infants.

    This randomized, comparative, phase-IIIb study conducted in France aimed to demonstrate whether seroprotection against diphtheria, tetanus and poliomyelitis 1 month after a single dose of REVAXIS (low-dose diphtheria) is non-inferior to seroprotection 1 month after a single dose of DT Polio (standard-dose diphtheria), both vaccines being given as a second booster to healthy children at 6 years of age. Children were randomly assigned to receive a single intramuscular dose of REVAXIS or DT Polio. Primary endpoints were the 1-month post-booster seroprotection rates for diphtheria, tetanus and poliovirus type-1, -2 and -3 antigens. Secondary endpoints were immunogenicity and safety observations. Of 788 children screened, 760 were randomized: REVAXIS group, 384 children; DT Polio group, 376 children. No relevant difference in demographic characteristics at baseline was observed between REVAXIS and DT Polio groups. Noninferiority of REVAXIS compared with DT Polio for seroprotection was demonstrated against diphtheria (respectively 98.6% and 99.3%), tetanus (respectively 99.6% and 100%) and poliovirus antigens (100% for each types in both groups). No allergic reactions to REVAXIS were reported. A benefit/risk ratio in favor of REVAXIS was suggested by the trend towards a better tolerability of REVAXIS compared with DT Polio regarding the rate of severe solicited injection-site reactions. The results support the use of REVAXIS as a booster at 6 years of age in infants who previously received a three-dose primary series within the first 6 months of life and a first booster including diphtheria, tetanus and poliovirus vaccine(s) given before 2 years of age.

    Horses are commonly vaccinated to protect against pathogens which are responsible for diseases which are endemic within the general horse population, such as equine influenza virus (EIV) and equine herpesvirus-1 (EHV-1), and against a variety of diseases which are less common but which lead to greater morbidity and mortality, such as eastern equine encephalomyelitis virus (EEE) and tetanus. This study consisted of two trials which investigated the antigenicity of commercially available vaccines licensed in the USA to protect against EIV, EHV-1 respiratory disease, EHV-1 abortion, EEE and tetanus in horses. Trial I was conducted to compare serological responses to vaccines produced by three manufacturers against EIV, EHV-1 (respiratory disease), EEE, and tetanus given as multivalent preparations or as multiple vaccine courses. Trial II compared vaccines from two manufacturers licensed to protect against EHV-1 abortion, and measured EHV-1-specific interferon-gamma (IFN-gamma) mRNA production in addition to serological evidence of antigenicity. In Trial I significant differences were found between the antigenicity of different commercial vaccines that should be considered in product selection. It was difficult to identify vaccines that generate significant immune responses to respiratory viruses. The most dramatic differences in vaccine performance occurred in the case of the tetanus antigen. In Trial II both vaccines generated significant antibody responses and showed evidence of EHV-1-specific IFN-gamma mRNA responses. Overall there were wide variations in vaccine response, and the vaccines with the best responses were not produced by a single manufacturer. Differences in vaccine performance may have resulted from differences in antigen load and adjuvant formulation.

    Full Text Available Abstract Introduction Tetanus rarely occurs in developed countries, but it can result in fatal complications including respiratory failure due to generalized muscle spasms. Magnesium infusion has been used to treat spasticity in tetanus, and its effectiveness is supported by several case reports and a recent randomized controlled trial. Case presentations Three Caucasian Greek men aged 30, 50 and 77 years old were diagnosed with tetanus and admitted to a general 12-bed intensive care unit in 2006 and 2007 for respiratory failure due to generalized spasticity. Intensive care unit treatment included antibiotics, hydration, enteral nutrition, early tracheostomy and mechanical ventilation. Intravenous magnesium therapy controlled spasticity without the need for additional muscle relaxants. Their medications were continued for up to 26 days, and adjusted as needed to control spasticity. Plasma magnesium levels, which were measured twice a day, remained in the 3 to 4.5 mmol/L range. We did not observe hemodynamic instability, arrhythmias or other complications related to magnesium therapy in these patients. All patients improved, came off mechanical ventilation, and were discharged from the intensive care unit in a stable condition. Conclusion In comparison with previous reports, our case series contributes the following meaningful additional information: intravenous magnesium therapy was used on patients already requiring mechanical ventilation and remained effective for up to 26 days (significantly longer than in previous reports without significant toxicity in two patients. The overall outcome was good in all our patients. However, the optimal dose, optimal duration and maximum safe duration of intravenous magnesium therapy are unknown. Therefore, until more data on the safety and efficacy of magnesium therapy are available, its use should be limited to carefully selected tetanus cases.

    To define conserved domains within the light (L) chains of clostridial neurotoxins, we determined the sequence of botulinum neurotoxin type B (BoNT/B) and aligned it with those of tetanus toxin (TeTx) and BoNT/A, BoNT/Cl, BoNT/D, and BoNT/E. The L chains of BoNT/B and TeTx share 51.6% identical

    The heavy chains of both botulinum neurotoxin type B and tetanus toxin form channels in planar bilayer membranes. These channels have pH-dependent and voltage-dependent properties that are remarkably similar to those previously described for diphtheria toxin. Selectivity experiments with anions and cations show that the channels formed by the heavy chains of all three toxins are large; thus, these channels could serve as "tunnel proteins" for translocation of active peptide fragments. These f...

    Haemagglutinating antibodies have been assessed in rabbits undergoing active- passive immunization against tetanus. The animals received 6 injections of horse immune serum, 400 UI/kg, and A1PO4 adsorbed toxoid, 0.35 Lf/kg, every 30th day. One the 5th day, after the first injection, E.A. antibodies appeared, at low levels, as a result of a passive immunization. Thereafter the tests became negative, up to the 70th day, when an active immunization emerged, with a 25 days delay in comparison with controls. Neutralization test in vivo behaved in the same way. The results stress once more the need to give up the use of heterologous immune sera in tetanus prophylaxis, in active-passive immunization as well. Arguments adding force to this point of view are: the sensibilization against heterologous proteins, the very low (if any) passive protective action, and, last not least, the delay in the emergence of active immunization: the only reliable shield against tetanus.

    Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vaccine. We describe a case of lichen planus in a hepatitis C virus-infected African American male occurring in temporal association with the administration of the tetanus-diphtheria-acellular pertussis vaccine. The patient's presentation was clinically consistent with lichen planus and confirmed by biopsy. It is likely that many cases of vaccine-induced lichen planus have gone unpublished or unrecognized. In areas with high prevalence of hepatitis C virus infection, we may expect to see more cases of vaccine-induced lichen planus especially in light of the updated Centers for Disease Control and Prevention tetanus-diphtheria-acellular pertussis vaccination recommendations. This case serves to educate healthcare providers about vaccine-induced lichen planus and, in particular, the need to counsel hepatitis C virus-infected patients about a potential risk of developing lichen planus following vaccination. We also reflect on current theories suggesting the T-cell-mediated pathogenesis of lichen planus and the role that hepatitis C virus and toxoid or protein vaccines may play in initiating the disease.

    World Health Organization (WHO) estimated in 2013 that 49,000 deaths all over the world were caused by neonatal tetanus. Only as recently as the year 2000, neonatal tetanus was a public health problem in 59 countries, but since then it has been eliminated in 36 of the countries concerned. The objective of this piece of work, therefore, was to investigate which strategies intended to increase demand for vaccination are effective in increasing anti-tetanus vaccination coverage of women in Sub Saharan Africa. We searched the following electronic databases from January 1989 to July 2016: Medline, EMBASE (Excerpta Medica Database), The Cochrane Library, Google Scholar, CINAHL (Cumulative Index to Nursing and Allied Health Literature), WHOLIS (World Health Organization Library Database), LILACS (Latin American and Caribbean Literature on Health Sciences) and contacted experts in the field. There were no restrictions to language or publication status. All study designs that could provide the information we sought were eligible, provided the studies were conducted in sub-Saharan Africa. Critical appraisal of all identified citations was done independently by two authors to establish the possible relevance of the articles for inclusion in the review. Our search strategy yielded 191 records and after assessment for eligibility, 6 papers met the criteria for inclusion. In Ivory Coast, after reorganization, health workers said they were satisfied with the work environment and the care provided in 91% and 96% of cases, respectively. In Kenya, the main factors contributing to having sufficiently immunized part of the population against tetanus are lower birth order, higher household wealth index, women's employment, making joint health-related decisions with a partner, and higher number of antenatal care visits. Particularly in Ethiopia, compared with other member countries, the size of the unimmunized population, reporting quality, fragileness of the health system, resource

    Revaxis(®) is a vaccine against diphtheria, tetanus and poliomyelitis (dT-IPV). This vaccine should not be administered by the intradermal or intravenous route. Poor injection techniques and related consequences are rare. We report a case of bursitis associated with reactive glenohumeral effusion complicated by bone erosion occurring after injection of the dT-IPV vaccine. A 26 year old patient was admitted for painful left shoulder causing functional impairment. Control magnetic resonance imaging showed bone oedema on the upper outer part of the humeral head, with a slight cortical irregularity, indicating that the vaccine was injected in contact with the bone at this location, causing erosion. Outcome was favourable after intra-articular corticosteroids. Reports of articular or periarticular injury after vaccination are extremely rare, in view of the substantial number of vaccines administered every year. The potential complications of vaccination are well known to general practitioners but under-reported in the literature. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To protect infants from pertussis infection, the Advisory Committee on Immunization Practices (ACIP) recommends women receive the tetanus toxoid, reduced diphtheria toxoid, acellular pertussis (Tdap) vaccine between 27 and 36weeks of pregnancy. Here, we assessed the association between timing of maternal Tdap vaccination during pregnancy and acute respiratory infection (ARI) in infants risks (RRs) and 95% confidence intervals (CIs) for the association between maternal Tdap vaccination during pregnancy and infant ARI at vaccination during pregnancy vs those who did not were 9% less likely to be diagnosed with an ARI at risk was 17% lower if vaccination was received between 27 and 36weeks of pregnancy (RR, 0.83; 95% CI, 0.74-0.93). Similar results were observed when comparing mothers who received Tdap vaccination prior to pregnancy in addition to Tdap vaccination between 27 and 36weeks of pregnancy versus mothers who only received vaccination prior to pregnancy (RR, 0.85; 95% CI, 0.74-0.98). Maternal Tdap vaccination between 27 and 36weeks of pregnancy was consistently protective against infant ARI in the first 2months of life vs no vaccination during pregnancy, regardless of Tdap vaccination prior to pregnancy. Our findings strongly support current ACIP guidelines recommending Tdap vaccination in late pregnancy for every pregnancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Recent studies suggest that exposure to perfluorinated alkylate substances (PFASs) may induce immunosuppression in humans and animal models. In this exploratory study, 12 healthy adult volunteers were recruited. With each subject, serum-PFAS concentrations were measured and their antibody responses prospectively followed for 30 days after a booster vaccination with diphtheria and tetanus. The results indicated that serum-PFAS concentrations were positively correlated and positively associated with age and male sex. The specific antibody concentrations in serum were increased from Day 4 to Day 10 post-booster, after which a constant concentration was reached. Serum PFAS concentrations showed significant negative associations with the rate of increase in the antibody responses. Interestingly, this effect was particularly strong for the longer-chain PFASs. All significant associations remained significant after adjustment for sex and age. Although the study involved a small number of subjects, these findings of a PFAS-associated reduction of the early humoral immune response to booster vaccination in healthy adults supported previous findings of PFAS immunosuppression in larger cohorts. Furthermore, the results suggested that cellular mechanisms right after antigen exposure should be investigated more closely to identify possible mechanisms of immunosuppression from PFAS.

    Full Text Available Purpose. In neocortical epilepsies not satisfactorily responsive to systemic antiepileptic drug therapy, local application of antiepileptic agents onto the epileptic focus may enhance treatment efficacy and tolerability. We describe the effects of focally applied valproate (VPA in a newly emerging rat model of neocortical epilepsy induced by tetanus toxin (TeT plus cobalt chloride (CoCl2. Methods. In rats, VPA ( or sodium chloride (NaCl ( containing polycaprolactone (PCL implants were applied onto the right motor cortex treated before with a triple injection of 75 ng TeT plus 15 mg CoCl2. Video-EEG monitoring was performed with intracortical depth electrodes. Results. All rats randomized to the NaCl group died within one week after surgery. In contrast, the rats treated with local VPA survived significantly longer (. In both groups, witnessed deaths occurred in the context of seizures. At least of the rats surviving the first postoperative day developed neocortical epilepsy with recurrent spontaneous seizures. Conclusions. The novel TeT/CoCl2 approach targets at a new model of neocortical epilepsy in rats and allows the investigation of local epilepsy therapy strategies. In this vehicle-controlled study, local application of VPA significantly enhanced survival in rats, possibly by focal antiepileptic or antiepileptogenic mechanisms.

    We have earlier found that a trivalent vaccine, containing antigenic components from both Gram-positive and Gram-negative bacteria, induced secretion of the endogenous pyrogen interleukin 6 (IL-6) when added to fresh human blood in vitro. The results of the present study showed that the IL-6 secretion was induced by toxoids derived from the Gram-positive bacterium Corynebacterium diphtheriae. However, fresh whole blood from different donors reacted differently to the stimulation. The blood from some donors induced secretion of large concentrations of IL-6, while the blood from other donors induced essentially no IL-6 secretion as a response to stimulation with diphtheria toxoid or a mixture of diphtheria and tetanus toxoids. Repeated testing over several years using blood from the same donor confirmed a donor-dependency of the reaction. This donor-dependency was only found for the toxoid, since blood from all donors reacted with approximately similar IL-6 production to stimulation by endotoxin from the Gram-negative bacterium Escherichia coli, known to be mediated via the toll-like receptor (TLR) 4. Also, no donor-dependecy was found to highly purified lipoteichoic acid from the Gram-positive bacteria Bacillus subtilis and Staphylococcus aureus, known to be mediated via TLR-2 and TLR-6. The receptors involved in stimulation by diphtheria toxoid are not known, but may differ from those used by endotoxin and lipoteichoic acid.

    Equine influenza is a contagious disease caused by equine influenza virus which belongs to the orthomyxovirus family. Outbreaks of equine influenza cause severe economic loses to the horse industry and consequently horses in competition are required to be regularly vaccinated against equine influenza. Unlike the existing inactivated vaccines, Equilis Prequenza Te is the only one able to induce protection against clinical disease and virus excretion after a primary vaccination course consisting of two vaccine applications 4-6 weeks apart until the recommended time of the third vaccination. In this paper we describe the duration of immunity profile, tested in an experimental setting according to European legislation, of this inactivated equine influenza and tetanus combination vaccine. In addition to influenza antigen, the formulation contains a second generation ISCOM (the so called ISCOMatrix) as an adjuvant. The vaccine aims at the induction of protection from the primary vaccination course until the time of annual revaccination 12 months later, against challenge with a virulent equine influenza strain. The protection against A/equine/Kentucky/95 (H3N8) at the time of annual revaccination was evidenced by a significant reduction of clinical signs of influenza, a significant reduction of virus excretion and a significant reduction of fever. The effect of the annual revaccination on the duration of immunity against influenza and tetanus was also studied by serology. For tetanus, as a consequence of the 24 months duration of immunity, an alternating annual vaccination schedule consisting of Prequenza and Prequenza Te is proposed after the first three doses of Prequenza Te.

    Boosting immunity to tetanus, diphtheria, and pertussis through the use of Tdap vaccines is routinely recommended at 11 to 12 years of age; some states, however, require Tdap for entry into middle school, which may begin at 10 years of age. This study was conducted to determine whether Tdap5 (Adacel), which is licensed for use in children beginning at 11 years of age, is as safe and immunogenic in 10-year-olds as it is in 11-year-olds. Children who had received 5 previous doses of any diphtheria-tetanus-acellular pertussis (DTaP) vaccine were enrolled in a phase IV clinical trial; 646 10-year-olds and 645 11-year-olds completed the study, which involved a single intramuscular dose of Tdap5 along with pre- and postvaccination serologies. Postvaccination geometric mean concentrations (GMCs) of antibody to pertussis antigens (pertussis toxoid, filamentous hemagglutinin, pertactin, and fimbria types 2 and 3) of 10-year-olds were noninferior to those of 11-year-olds, as were booster response rates for all pertussis antibodies, except for those to fimbrial antigens (94% and 97%, respectively). Seroprotection rates among 10-year-olds for tetanus and diphtheria were noninferior to those in 11-year-olds. Rates of injection site reactions, solicited systemic reactions, and unsolicited adverse events, adverse reactions, and serious adverse events were similar in the two groups. These data support the conclusion that Tdap5 is safe and immunogenic in 10-year-olds. (This study has been registered at ClinicalTrials.gov under registration no. NCT01311557.).

    The C-terminal domain of the heavy chain of tetanus toxin (Hc-TeTx) is a nontoxic peptide with demonstrated in vitro and in vivo neuroprotective effects against striatal dopaminergic damage induced by 1-methyl-4-phenylpyridinium and 6-hydoxydopamine, suggesting its possible therapeutic potential in Parkinson's disease. Methamphetamine, a widely abused psychostimulant, has selective dopaminergic neurotoxicity in rodents, monkeys, and humans. This study was undertaken to determine whether Hc-TeTx might also protect against methamphetamine-induced dopaminergic neurotoxicity and the consequent motor impairment. For this purpose, we treated mice with a toxic regimen of methamphetamine (4mg/kg, 3 consecutive i.p. injections, 3 hours apart) followed by 3 injections of 40 ug/kg of Hc-TeTx into grastrocnemius muscle at 1, 24, and 48 hours post methamphetamine treatment. We found that Hc-TeTx significantly reduced the loss of dopaminergic markers tyrosine hydroxylase and dopamine transporter and the increases in silver staining (a well stablished degeneration marker) induced by methamphetamine in the striatum. Moreover, Hc-TeTx prevented the increase of neuronal nitric oxide synthase but did not affect microglia activation induced by methamphetamine. Stereological neuronal count in the substantia nigra indicated loss of tyrosine hydroxylase-positive neurons after methamphetamine that was partially prevented by Hc-TeTx. Importantly, impairment in motor behaviors post methamphetamine treatment were significantly reduced by Hc-TeTx. Here we demonstrate that Hc-TeTx can provide significant protection against acute methamphetamine-induced neurotoxicity and motor impairment, suggesting its therapeutic potential in methamphetamine abusers. © The Author 2016.

    Full Text Available Background: Previous studies have identified various risk factors for neonatal tetanus (NNT in rural areas of Pakistan. The present matched case control study was conducted to further evaluate these risk factors in an urban setting. Aim: The study was carried out to identify risk factors for NNT in Karachi. Materials and Methods: Patients of NNT (n = 125 diagnosed from January 1998 to February 2001 were recruited through a surveillance system of Expanded Programme on Immunization (EPI. Two neighbourhood controls (n = 250 were matched for each case for gender and date of birth of the case. Statistical Analysis: Conditional logistic regression was performed to assess the independent effect of factors associated with NNT. Results: The final multivariable model identified subsequent application of substances on the umbilical cord (adjusted matched odds ratio [adj. mOR] = 5.1 [2.7-9.7], home delivery (adj. mOR = 1.8; 95% CI: 1.1- 3.1 and illiterate mother (adj. mOR = 1.6; 95% CI: 1.0- 2.0 as risk factors for NNT after adjusting for other variables in the model. Population attributable risk per cent (PAR % for subsequent cord application was 69% and PAR % for home delivery was 31%. Conclusion: Health planners, while formulating control strategies through immunization programmes should also take into account the impact of post-delivery practices, such as 'subsequent cord application' along with pre-delivery practices. Health awareness regarding appropriate post-delivery practices should be promoted and counselling of pregnant women for giving preference to health care setting for delivery is also crucial.

    The incidence of pertussis in the United States has increased since the 1990s. Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination of pregnant women provides passive protection to infants. Tdap vaccination is currently recommended for pregnant women during each pregnancy, but coverage among pregnant women and women of childbearing age has been suboptimal. Data from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) and 2013 National Health Interview Survey (NHIS) were used to determine national and state-specific Tdap vaccination coverage among women of childbearing age by self-reported pregnancy status at the time of the survey. Although this study could not assess coverage of Tdap vaccination received during pregnancy because questions on whether Tdap vaccination was received during pregnancy were not asked in BRFSS and NHIS, demographic and access-to-care factors associated with Tdap vaccination coverage in this population were assessed. Tdap vaccination coverage among all women 18-44 years old was 38.4% based on the BRFSS and 23.3% based on the NHIS. Overall, coverage did not differ by pregnancy status at the time of the survey. Coverage among all women 18-44 years old varied widely by state. Age, race and ethnicity, education, number of children in the household, and access-to-care characteristics were independently associated with Tdap vaccination in both surveys. We identified associations of demographic and access-to-care characteristics with Tdap vaccination that can guide strategies to improve vaccination rates in women during pregnancy.

    The skin is immunologically very potent because of the high number of antigen-presenting cells in the dermis and epidermis, and is therefore considered to be very suitable for vaccination. However, the skin’s physical barrier, the stratum corneum, prevents foreign substances, including vaccines, from entering the skin. Microneedles, which are needle-like structures with dimensions in the micrometer range, form a relatively new approach to circumvent the stratum corneum, allowing for minimally invasive and pain-free vaccination. In this study, we tested ceramic nanoporous microneedle arrays (npMNAs), representing a novel microneedle-based drug delivery technology, for their ability to deliver the subunit vaccines diphtheria toxoid (DT) and tetanus toxoid (TT) intradermally. First, the piercing ability of the ceramic (alumina) npMNAs, which contained over 100 microneedles per array, a length of 475 µm, and an average pore size of 80 nm, was evaluated in mouse skin. Then, the hydrodynamic diameters of DT and TT and the loading of DT, TT, and imiquimod into, and subsequent release from the npMNAs were assessed in vitro. It was shown that DT and TT were successfully loaded into the tips of the ceramic nanoporous microneedles, and by using near-infrared fluorescently labeled antigens, we found that DT and TT were released following piercing of the antigen-loaded npMNAs into ex vivo murine skin. Finally, the application of DT- and TT-loaded npMNAs onto mouse skin in vivo led to the induction of antigen-specific antibodies, with titers similar to those obtained upon subcutaneous immunization with a similar dose. In conclusion, we show for the first time, the potential of npMNAs for intradermal (ID) immunization with subunit vaccines, which opens possibilities for future ID vaccination designs. PMID:29375544

It was shown that DT and TT were successfully loaded into the tips of the ceramic nanoporous microneedles, and by using near-infrared fluorescently labeled antigens, we found that DT and TT were released following piercing of the antigen-loaded npMNAs into ex vivo murine skin. Finally, the application of DT- and TT-loaded npMNAs onto mouse skin in vivo led to the induction of antigen-specific antibodies, with titers similar to those obtained upon subcutaneous immunization with a similar dose. In conclusion, we show for the first time, the potential of npMNAs for intradermal (ID immunization with subunit vaccines, which opens possibilities for future ID vaccination designs.

    To identify prognostic variables for adult equids and foals with tetanus. Multicenter retrospective study (2000-2014). Twenty Western, Northern, and Central European university teaching hospitals and private referral centers. One hundred fifty-five adult equids and 21 foals with tetanus. None. Variables from history and clinical examination were statistically compared between survivors and nonsurvivors (adults: 49 survivors, 85 nonsurvivors; foals: 7 survivors, 10 nonsurvivors). Cases euthanized for financial reasons were excluded. Mortality rates in adults and foals were 68.4% and 66.7%, respectively. Variables associated with survival in adults included: standing, normal intestinal sounds and defecation, voluntarily drinking, eating soft or normal food, lower heart and respiratory rates, high base excess on admission, longer diagnosis time, treatment and hospitalization delay, and mild severity grade. Variables associated with death included: anorexia, dysphagia, dyspnea, low blood potassium concentration on admission, moderate and severe disease grading, development of dysphagia, dyspnea, recumbency and seizures during hospitalization, treatment with glycerol guaiacolate, intravenous fluids, and intravenous glucose solutions. Variables associated with survival in foals included standing on admission, voluntarily eating soft food and drinking, older age, and longer hospitalization delay. Outcome was not different between different tetanus antitoxin (TAT) dosages, although there was a trend of increasing survival rate with increasing TAT dosages. Cases with appropriate vaccination prior to development of tetanus were rare, but had improved outcome and shorter hospitalization. Prognosis for equine tetanus is poor with similar outcome and prognostic factors in foals and adults. The prognostic assessment of cases with tetanus provides clinicians with new evidence-based information related to patient management. Several prognostic indicators relate to the ability to

    The use of tetanus toxoid as a recall antigen to investigate equine immune responses would be, in theory, a useful and cost-effective model in vitro. However, by using various regimens for culturing peripheral blood mononuclear cells from horses previously immunised with toxoid no proliferative response to the antigen was obtained in vitro, whereas lymph node mononuclear cells from the same animals proliferated significantly in response to it. The lack of response by the peripheral blood mononuclear cells was not due to the presence of a suppressive factor but to a lack of recognition of the antigen by the T cells of the peripheral blood.

    An acellular Pertussis (aP) vaccine containing recombinant genetically detoxified Pertussis Toxin (PTgen), Filamentous Hemagglutinin (FHA) and Pertactin (PRN) has been developed by BioNet-Asia (BioNet). We present here the results of the first clinical study of this recombinant aP vaccine formulated alone or in combination with tetanus and diphtheria toxoids (TdaP). A phase I/II, observer-blind, randomized controlled trial was conducted at Mahidol University in Bangkok, Thailand in healthy adult volunteers aged 18-35 y. The eligible volunteers were randomized to receive one dose of either BioNet's aP or Tetanus toxoid-reduced Diphtheria toxoid-acellular Pertussis (TdaP) vaccine, or the Tdap Adacel® vaccine in a 1:1:1 ratio. Safety follow-up was performed for one month. Immunogenicity was assessed at baseline, at 7 and 28 d after vaccination. Anti-PT, anti-FHA, anti-PRN, anti-tetanus and anti-diphtheria IgG antibodies were assessed by ELISA. Anti-PT neutralizing antibodies were assessed also by CHO cell assay. A total of 60 subjects (20 per each vaccine group) were enrolled and included in the safety analysis. Safety laboratory parameters, incidence of local and systemic post-immunization reactions during 7 d after vaccination and incidence of adverse events during one month after vaccination were similar in the 3 vaccine groups. One month after vaccination, seroresponse rates of anti-PT, anti-FHA and anti-PRN IgG antibodies exceeded 78% in all vaccine groups. The anti-PT IgG, anti-FHA IgG, and anti-PT neutralizing antibody geometric mean titers (GMTs) were significantly higher following immunization with BioNet's aP and BioNet's TdaP than Adacel® (Pdiphtheria GMTs at one month after immunization were comparable in all vaccine groups. All subjects had seroprotective titers of anti-tetanus and anti-diphtheria antibodies at baseline. In this first clinical study, PTgen-based BioNet's aP and TdaP vaccines showed a similar tolerability and safety profile to Adacel

    By means of semipurified tetanus toxin for solid phase coating in an enzyme immunoassay (ELISA) for detection of specific IgG and IgM antibodies a detection limit of 0.02 IU per litre was achieved. The addition of serum from animals like horses or goats as inert protein to the dilution medium was omitted to prevent a displacement of human antibodies by antitetanus antibodies present in the animals sera. The specificity of the ELISA was demonstrated by inhibition experiments with soluble antigen and in an ELISA for detection of anti-tetanus toxin antibodies from mice immunized with the toxoid from the different purification steps.

    Diphtheria-tetanus-acellular pertussis vaccine (DTaP) developed in Japan is now widely used worldwide. DTaP is safer than the diphtheria-tetanus-whole-cell pertussis vaccine (DTwP) and has fewer severe side effects, but local reactions such as redness, swelling, and induration are still reported. The pathophysiological mechanism of these reactions is controversial. To clarify the cause of local reactions, we conducted studies using the mouse model. After administering either one or two abdominal subcutaneous DTaP inoculations, we observed changes in histopathology at the injection site at 24h, 48h, and 7 days. The control group, inoculated with physiologic saline, showed no significant changes either pathologically or with the naked eye. All mice after DTaP vaccination showed indurations at the injection site. Pathologically, we watched leukocyte invasion into or around the site, especially neutrophils and eosinophils. After the first vaccination, the extent of the invasion was strong 24h and 7 days later. At 24h following the second vaccination, a dramatic leukocyte invasion seen persisted at 7days. At 7 days after the first vaccination, peripheral fibrosis had begun, and when a second vaccination was administered, it began even earlier at the second site. These histopathological changes show that local reactions are caused by both inflammatory and allergic responses. Because this mouse study resulted in the same pattern of reactions observed in humans, this method will be useful for studies focusing on local reactions.

    Published data on the safety of tetanus-diphtheria-acellular pertussis vaccine (Tdap) in persons aged ≥65 years are limited. This study aims to examine a large cohort of Tdap users ≥65 years for evidence of increased risk of adverse events following vaccination. A matched cohort study design and a self-controlled case series (SCCS) design were used. The study population was adults aged ≥65 years who received the Tdap or tetanus and diphtheria (Td) vaccine during 1 January 2006-31 December 2010 at 7 health maintenance organizations in the United States. Seven major groups of prespecified events were identified electronically by diagnostic codes. The study included 119 573 Tdap vaccinees and the same number of Td vaccinees. The results indicated that the risk of the prespecified events following Tdap was comparable to that following Td vaccination in this elderly population. There was a small increased rate of codes suggesting medically attended inflammatory or allergic events in 1-6 days following Tdap in the SCCS analysis (incidence rate ratio, 1.59 [95% confidence interval, 1.40-1.81]). Although there is a small increased risk of medically attended inflammatory or allergic events in 1-6 days following Tdap compared to other time periods, it is no more common than that following Td. This study provides empirical safety data suggesting that immunizing adults aged ≥65 years with Tdap to reduce the risk of pertussis in the elderly and their contacts should not have untoward safety consequences.

    To assess the effects of psychological stress on the antibody response to tetanus vaccine adjusting for cytokine gene polymorphisms and other nongenetic factors in caregivers of patients with Alzheimer's disease (AD). A family-based follow-up study was conducted in 119 spouses and offspring of community-dwelling patients with AD. Psychological stress was measured by the Perceived Stress Scale (PSS) and the Center for Epidemiologic Studies Depression (CES-D) scale at baseline and 1 month after the vaccination. Nutritional status, health behaviors, comorbidity, and stress-buffering factors were assessed by self-administered questionnaires, 10 single nucleotide polymorphisms (SNP) from six selected cytokines genotyped, and anti-tetanus toxoid immunoglobulin G (IgG) concentrations tested using enzyme-linked immunosorbent assays. The effects of stress and other potential confounders were assessed by mixed models that account for familial correlations. The baseline PSS score, the baseline CES-D score, the interleukin-10-1082 A>G SNP GG genotype, and the baseline anti-tetanus IgG were inversely associated with antibody fold increase. Both psychological stress and cytokine gene polymorphisms affected antibody fold increase. The study provided additional support for the detrimental effects of psychological stress on the antibody response to tetanus vaccine.

    Persistence of antibodies after a single dose of Tdap vaccine (tetanus, diphtheria, and 5-component acellular pertussis vaccine) was evaluated in a follow-up study of adolescents (N=324) and adults (N=644) who had received Tdap in earlier clinical trials. Outcome measures were seroprotection (tetanus and diphtheria) or seropositivity (pertussis) and geometric mean concentrations. Humoral immune responses to all antigens were robust 1 month after initial immunization, decreased at subsequent measurements, but continued to exceed pre-immunization levels 1, 3, 5, and 10 years later. Protective levels of diphtheria and tetanus antitoxin persisted in 99.3% of adolescents 10 years after a booster dose of Tdap. Seropositivity to 1 or more pertussis antigens also persisted in most adolescents for 10 years. Although tetanus antitoxin responses were similar in adults to those observed in adolescents, diphtheria antitoxin titers were lower, reflecting the fact that a smaller proportion of adults had received diphtheria toxoid in the previous 10 years compared to adolescents. These data will contribute to the selection of the optimal interval for repeat doses of Tdap. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available A randomized, double-blinded study evaluating the immunogenicity, safety and consistency of production of a combined diphtheria-tetanus-pertussis-Haemophilus influenzae type b vaccine entirely produced in Brazil by Bio-Manguinhos and Instituto Butantan (DTP/Hib-BM was undertaken. The reference vaccine had the same DTP vaccine but the Hib component was produced using purified materials supplied by GlaxoSmithKline (DTP/Hib-GSK, which is registered and has supplied the Brazilian National Immunization Program for over more than five years. One thousand infants were recruited for the study and received vaccinations at two, four and six months of age. With respect to immunogenicity, the vaccination protocol was followed in 95.6% and 98.4% of infants in the DTP/Hib-BM and DTP/Hib-GSK groups, respectively. For the Hib component of the study, there was 100% seroprotection (>0.15 µg/mL with all three lots of DTP/Hib-BM and DTP/Hib-GSK. The geometric mean titer (GMT was 9.3 µg/mL, 10.3 µg/mL and 10.3 µg/mL for lots 1, 2 and 3 of DTP/Hib-BM, respectively, and the GMT was 11.3 g/mL for DTP/Hib-GSK. For diphtheria, tetanus and pertussis, seroprotection was 99.7%, 100% and 99.9%, respectively, for DTP/Hib-BM, three lots altogether and 99.2%, 100% and 100% for DTP/Hib-GSK. GMTs were similar across all lots and vaccines. Adverse events rates were comparable among the vaccine groups. The Brazilian DTP/Hib vaccine demonstrated an immunogenicity and reactogenicity profile similar to that of the reference vaccine.

    A survey of the characteristics of traditional birth attendants in Krabi Province, Thailand, where the incidence rate of tetanus neonatorum was the highest in the country, was conducted in order to obtain background information necessary for planning a training curriculum and to evaluate previous training courses. Five second year medical students were used as research assistants. After the questionnaire was constructed and tested, the students went to visit a sample of 116 traditional birth attendants (TBAs) to interview them about their personal backgrounds, techniques and practices in delivery and beliefs and attitudes towards midwifery. The study revealed that these TBAs were a mixture of Buddhist and Islamic females whose literacy rate was 53 percent. Ninety-one per cent knew about the availability of an injection for antenatal care at the health center, but only about half knew that it was for tetanus prevention. More than half provided antenatal care at their own home but 85 per cent conducted delivery at the client's home. About eighty per cent of the TBAs claimed that sterilization of instruments was performed. However, dressing of the umbilical cord was done inappropriately using various kinds of powders by about 40 per cent. The majority of TBAs had experience with complicated labors but only 30 per cent were referred, perhaps, due to excessive self-confidence and supernatural beliefs. The trained TBAs possessed a higher level of knowledge of immunization and sterile techniques for cord cutting and dressing of the stumps of the umbilical cord than the untrained group. However, knowledge of sterilization of instruments was not significantly different, indicating a need to improve teaching in this area.(ABSTRACT TRUNCATED AT 250 WORDS)

  14. Experimental studies on the influence of a neutron irradiation on immunity as studied by means of a combined Tetanus-Novyi vaccination of mice

    1983-01-01

    Experiments were done in 4 variations. Antibody titers were tested with ELISA and HA test. Neutron radiation caused immunosuppression. The effect was increased when irradiation was given one day before vaccination, compared to irradiation given one day after irradiation. Enhancing the radiation dose caused a stronger immunosuppression. Neutron radiation also had a negative influence on the secondary immune reaction when given between the vaccinations (III). Given after the second vaccination the irradiation stimulated the immune response. If Tetanus and Novyi toxoid are used for vaccination in combination, the Novyi antigen stimulus is weakened by the Tetanus component. This fact also occurs after neutron irradiation. This shows that the irradiation effect also depends on the antigen itself. Best protection against radiation will be reached by vaccinating and revaccinating before the insult. Also a revaccination after a radiation insult will be useful. (orig.) [de

    Few data are available on the seroprotection status of HIV1-infected patients with respect to vaccine-preventable diseases. To describe, in a population of HIV1-infected migrants on stable, effective ART therapy, the seroprevalence of diphtheria, poliomyelitis, tetanus, yellow fever antibodies and serostatus for hepatitis B, and to identify factors associated with seroprotection. Vaccine responses against diphtheria, tetanus, poliomyelitis and yellow fever were also studied. Sub-Saharan African patients participating in the ANRS-VIHVO cohort were enrolled prior to travel to their countries of origin. Serologic analyses were performed in a central laboratory before and after the trip. Univariate and multivariate logistic regression was used to identify factors associated with initial seroprotection. 250 patients (99 men and 151 women) were included in the seroprevalence study. Median age was 45 years (IQR 39-52), median CD4 cell count was 440/μL (IQR 336-571), and 237 patients (95%) had undetectable HIV1 viral load. The initial seroprevalence rates were 69.0% (95%CI 63.2-74.7) for diphtheria, 70.7% (95%CI 65.0-76.3) for tetanus, and 85.9% (95%CI 81.6-90.2) for yellow fever. Only 64.4% (95%CI 58.5-70.3) of patients had protective antibody titers against all three poliomyelitis vaccine strains before travel. No serological markers of hepatitis B were found in 18.6% of patients (95%CI 13.7-23.3). Patient declaration of prior vaccination was the only factor consistently associated with initial seroprotection. We found a low prevalence of seroprotection against diphtheria, poliomyelitis, tetanus and hepatitis B. HIV infected migrants living in France and traveling to their native countries need to have their vaccine schedule completed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A new reduced-dose tetanus-diphtheria (Td) vaccine was developed in Korea, and phase I and II clinical trials were successfully undertaken. We conducted this double-blind, randomized, multicenter phase III clinical trial to assess the immunogenicity and safety of the new Td vaccine. Healthy adolescents 11-12 years of age were enrolled and randomized to receive the new Td vaccine (study group) or a commercially available Td vaccine (control group). Blood samples were collected prior to and 4 weeks after the vaccination. Between the study and control groups, seroprotection rate, booster response, and geometric mean titer of antibodies against diphtheria and tetanus toxoids were compared after the vaccination. All solicited and unsolicited adverse events and serious adverse events during the 6-week study period were monitored. A total of 164 adolescents received vaccination, and 156 of them were evaluated to assess immunogenicity. The seroprotection rate and geometric mean titer for antibodies against diphtheria were significantly higher in the study group, whereas those against tetanus were significantly higher in the control group. However, all seroprotection rates against diphtheria and tetanus in the study and control groups were high: 100% against diphtheria and tetanus in the study group, and 98.7% against diphtheria and 100% against tetanus in the control group. No significant differences in the frequency of solicited and unsolicited adverse events were observed between the two vaccine groups. The new Td vaccine is highly immunogenic and safe, and this new Td vaccine can be effectively used for preventing diphtheria and tetanus. Copyright © 2015. Published by Elsevier B.V.

    La transformación a toxoide de la toxina tetánica sin purificar y libre de células, se evaluó bajo condiciones variables de pH, temperatura de incubación inicial (primera semana, potencial de óxido-reducción, concentración de toxina tetánica y concentración de formaldehído. Al tratar la toxina tetánica en un medio de reacción neutro existe menor porcentaje de pérdida de la proteína tetánica. Para las condiciones actuales de detoxificación, no existe dependencia de la concentración de formaldehído y la concentración de proteína tetánica inicial, variando de forma independiente el valor floculante. La reacción formaldehídotoxina es lenta a bajas temperaturas, con menor disminución del valor floculante y sin influencia del potencial redox en el valor floculante y en la pérdida de toxicidad. 

    The transformation to toxoid of tetanus toxin without purification and cells free, was evaluated under variable conditions such as pH, initial incubation temperature (first week, potencial of oxidation-reduction, tetanus toxin concentration and formaldehyde concentration. When tetanus toxin is treated in a neutral reactional media there is a less lost of tetanus protein. To the present detoxification conditions there is not dependence between the formaldehyde concentration and the initial tetanus protein concentration changing independtly the flocculant value. The formaldehyde-toxin reaction is slow at low temperatures, with a lower diminution of the flocculant value and without the redox potential influence in the flocculant value and in the lost of toxicity.

    Full Text Available Despite success in expanded program immunization for an increase in vaccination coverage in the children of world, timeliness and schedule of vaccination remains as one of the challenges in public health. This study purposed to demonstrate the related factors of delayed diphtheria-tetanus-pertussis (DTP vaccination using life table approach. A historical cohort study conducted in the poor areas of five large Iran cities. Totally, 3610 children with 24-47 months old age who had documented vaccination card were enrolled. Time of vaccination for the third dose of DTP vaccine was calculated. Life table survival was used to calculate the proportional probability of vaccination in each time. Wilcoxon test was used for the comparison proportional probability of delayed vaccination based on studies factors. The overall median delayed time for DTP3 was 38.52 days. The Wilcoxon test showed that city, nationality, education level of parents, birth order and being in rural areas are related to the high probability of delay time for DTP3 vaccination (P 0.05. Being away from the capital, a high concentration of immigrants in the city borders with a low socioeconomic class leads to prolonged delay in DTP vaccination time. Special attention to these areas is needed to increase the levels of parental knowledge and to facilitate access to the health services care.

    In order to search the preparation process and optimazing dosage ratio of adsorbed diphtheria-tetanus-acellular pertussis and sabin inactivated poliovirus combined vaccine (DTaP-sIPV), the neutralizing antibody titers of IPV induced by different concentration of DTaP-sIPV were investigated on rats. Two batches of DTaP-sLPV were produced using different concentration of sIPV and the quality control was carried. Together with sabin-IPV and DTaP-wIPV ( boostrix-polio, GSK, Belgium) as control group, the DTaP-sIPV were administrated on three-dose schedule at 0, 1, 2 month on rats. Serum sample were collected 30 days after each dose and neutralizing antibody titers against three types poliovirus were determined using micro-neutralization test. Two batches of prepared DTaP-sIPV and control sLPV were according to the requirement of Chinese Pharmacopoeia (Volume III, 2005 edition) and showed good stability. The seropositivity rates were 100% for sabin inactivated poliovirus antigen in all groups. The GMTs (Geometric mean titers) of neutralizing antibodies against three types poliovirus increased. The prepared DTaP-sIPV was safe, stable and effective and could induced high level neutralizing antibody against poliovirus on rats.

    Full Text Available Abstract Background The most common cause of idiopathic nephrotic syndrome in children and younger adults is the minimal change nephrotic syndrome (MCNS. In the elderly MCNS is relatively uncommon. Over the last decade some reports suggest a rare but possible association with the administration of various vaccines. Case presentation A 82-year old Caucasian female presented with pronounced nephrotic syndrome (proteinuria of 7.1 g/d, hypoproteinemia of 47 g/l. About six weeks prior to admission, she had received a combination vaccination for tetanus, diphtheria and poliomyelitis as a booster-vaccination from her general practitioner. The renal biopsy revealed typical minimal change lesions. She responded well to the initiated steroid treatment. As through physical examination as well as extensive laboratory and imaging studies did neither find any evidence for malignancies nor infections we suggest that the minimal change nephrotic syndrome in this patient might be related to the activation of the immune system triggered by the vaccination. Conclusion Our case as well as previous anecdotal reports suggests that vaccination and the resulting stimulations of the immune system might cause MCNS and other severe immune-reactions. Increased awareness in that regard might help to expand the database of those cases.

    Full Text Available As a result of the advances in the control of pulmonary insufficiency in tetanus, the cardiovascular system has increasingly been shown to be a determining factor in morbidity and mortality but detailed knowledge of the cardiovascular complications in tetanus is scanty. The 24h-Holter was carried out in order to detect arrhythmias and sympathetic overactivity in 38 tetanus patients admitted to an ICU. The SDNN Index (standard deviation from the normal R-to-R intervals, was useful in detecting adrenergic tonus, and ranged from 64.1 ± 27 in the more severe forms of tetanus to 125 ± 69 in the milder ones. Sympathetic overactivity occurred in 86.2% of the more severe forms of the disease, but was also detected in 33% of the milder forms. Half the patients had their sympathetic overactivity detected only by the Holter. The most frequent arrhythmias were isolated supraventricular (55.2% and ventricular (39.4% extrasystoles. There was no association of the arrhythmias with the clinical form of tetanus or with the presence of sympathetic overactivity. The present study demonstrated that major cardiovascular dysfunction, particularly sympathetic overactivity, occurs in all forms of tetanus, even in the milder ones. This has not been effectively detected with traditional monitoring in ICU and may not be properly treated.Com os avanços no controle da insuficiência respiratória no tétano, o sistema cardiovascular tem participado de forma crescente na morbidade e mortalidade da doença, mas o conhecimento dessas complicações é escasso.

  8. Screening Mixtures of Small Molecules for Binding to Multiple Sites on the Surface Tetanus Toxin C Fragment by Bioaffinity NMR

    The clostridial neurotoxins include the closely related tetanus (TeNT) and botulinum (BoNT) toxins. Botulinum toxin is used to treat severe muscle disorders and as a cosmetic wrinkle reducer. Large quantities of botulinum toxin have also been produced by terrorists for use as a biological weapon. Because there are no known antidotes for these toxins, they thus pose a potential threat to human health whether by an accidental overdose or by a hostile deployment. Thus, the discovery of high specificity and affinity compounds that can inhibit their binding to neural cells can be used as antidotes or in the design of chemical detectors. Using the crystal structure of the C fragment of the tetanus toxin (TetC), which is the cell recognition and cell surface binding domain, and the computational program DOCK, sets of small molecules have been predicted to bind to two different sites located on the surface of this protein. While Site-1 is common to the TeNT and BoNTs, Site-2 is unique to TeNT. Pairs of these molecules from each site can then be linked together synthetically to thereby increase the specificity and affinity for this toxin. Electrospray ionization mass spectroscopy was used to experimentally screen each compound for binding. Mixtures containing binders were further screened for activity under biologically relevant conditions using nuclear magnetic resonance (NMR) methods. The screening of mixtures of compounds offers increased efficiency and throughput as compared to testing single compounds and can also evaluate how possible structural changes induced by the binding of one ligand can influence the binding of the second ligand. In addition, competitive binding experiments with mixtures containing ligands predicted to bind the same site could identify the best binder for that site. NMR transfer nuclear Overhauser effect (trNOE) confirm that TetC binds doxorubicin but that this molecule is displaced by N-acetylneuraminic acid (sialic acid) in a mixture that

    In vitro studies have shown that anti-malarial drugs suppress immunity. In this study, the effects of chloroquine and proguanil (Paludrine) on the cellular and humoral immune system were measured by two in vivo methods: 1) cell-mediated immunity (delayed cutaneous hypersensitivity) i.e., skin tests with seven delayed-type common antigens (Multitest) and 2) humoral immunity by measurement of specific antibody response to vaccination. Sixty healthy young individuals were randomized into four groups and given 1) no treatment (controls), 2) chloroquine diphosphate (500 mg/week), 3) chloroquine diphosphate (1,000 mg/week), or 4) proguanil hydrochloride (200 mg/day) for six weeks. Skin testing was performed on days 0 and 28. Vaccinations with diphtheria, tetanus, polio, and pneumococcal polysaccharide antigen vaccines were performed on day 28, and the presence of specific antibodies was determined on days 0, 28, and 42. The skin tests induced a significant increase in skin reactive areas from day 0 to day 28 in all groups. Furthermore, the skin test induced an increase in the level of specific IgG for diphtheria and tetanus, but had no effect on antibodies to antigens not included in the skin test. The results showed that there were no significant differences among the four groups regarding skin test areas and increases in antibody titers following vaccination. Therefore, it is concluded that in healthy persons, six weeks intake of chloroquine, even in double doses, or proguanil in chemoprophylactic dosages, does not induce any detectable suppression of delayed-type hypersensitivity or vaccination responses to diphtheria, tetanus, polio, or pneumococcal polysaccharide antigens.

    Full Text Available Abstract Background Local reactions are the most commonly reported adverse events following tetanus and diphtheria toxoid (Td vaccine and the risk of local reactions may increase with number of prior Td vaccinations. Methods To estimate the risk of medically attended local reactions following Td vaccination in adolescents and young adults we conducted a six-year retrospective cohort study assessing 436,828 Td vaccinations given to persons 9 through 25 years of age in the Vaccine Safety Datalink population from 1999 through 2004. Results Overall, the estimated risk of a medically attended local reaction was 3.6 events per 10,000 Td vaccinations. The lowest risk (2.8 events per 10,000 vaccinations was found in the 11 to 15 year old age group. In comparison with that group, the event risks were significantly higher in both the 9 to 10 and 21 to 25 year old age groups. The risk of a local reaction was significantly higher in persons who had received another tetanus and diphtheria toxoid containing vaccine (TDCV in the previous five years (incidence rate ratio, 2.9; 95% confidence interval, 1.2 to 7.2. Twenty-eight percent of persons with a local reaction to Td vaccine were prescribed antibiotics. Conclusion Medically attended local reactions were uncommon following Td vaccination. The risk of those reactions varied by age and by prior receipt of TDCVs. These findings provide a point of reference for future evaluations of the safety profile of newer vaccines containing tetanus or diphtheria toxoid.

    Accelerated granulocyte and platelet recovery following peripheral blood stem cell transplantation (PBSCT) are well documented. We hypothesize that functional immunity may also be enhanced in PBSCT and performed a phase II trial of immunizations in patients with lymphoma undergoing autologous transplantation with peripheral blood stem cells or bone marrow. Seventeen BMT and 10 PBSCT recipients were immunized at 3, 6, 12, and 24-months post-transplantation with Haemophilus influenzae type b (HIB)-conjugate and tetanus toxoid (TT) vaccines. IgG anti-HIB and anti-TT antibody concentrations were measured and compared between the two groups. Geometric mean IgG anti-HIB antibody concentrations were significantly higher for PBSCT recipients compared to BMT recipients at 24 months post-transplantation (11.3 micrograms/ml vs 0.93 microgram/ml, P = 0.051) and following the 24 month immunization (66.2 micrograms/ml vs 1.30 micrograms/ml, P = 0.006). Similar results were noted for IgG anti-TT antibody with significantly higher geometric mean antibody concentrations in the PBSCT group at 24 months post-transplantation (182 micrograms/ml vs 21.6 micrograms/ml, P = 0.039). Protective levels of total anti-HIB antibody were achieved earlier in PBSCT recipients compared with those of BMT recipients. PBSCT recipients had higher antigen-specific antibody concentrations following HIB and TT immunizations. These results suggest enhanced recovery of humoral immunity in PBSCT recipients and earlier protection against HIB with immunization.

    Pertussis incidence has increased significantly in Brazil since 2011, despite high coverage of whole-cell pertussis containing vaccines in childhood. Infants cost-effectiveness of introducing universal maternal vaccination with tetanus-diphtheria-acellular pertussis vaccine (Tdap) into the National Immunization Program in Brazil. Economic evaluation using a decision tree model comparing two strategies: (1) universal vaccination with one dose of Tdap in the third trimester of pregnancy and (2) current practice (no pertussis maternal vaccination), from the perspective of the health system and society. An annual cohort of newborns representing the number of vaccinated pregnant women were followed for one year. Vaccine efficacy were based on literature review. Epidemiological, healthcare resource utilization and cost estimates were based on local data retrieved from Brazilian Health Information Systems. Costs of epidemiological investigation and treatment of contacts of cases were included in the analysis. No discount rate was applied to costs and benefits, as the temporal horizon was one year. Primary outcome was cost per life year saved (LYS). Univariate and best- and worst-case scenarios sensitivity analysis were performed. Maternal vaccination of one annual cohort, with vaccine effectiveness of 78%, and vaccine cost of USD$12.39 per dose, would avoid 661 cases and 24 infant deaths of pertussis, save 1800 years of life and cost USD$28,942,808 and USD$29,002,947, respectively, from the health system and societal perspective. The universal immunization would result in ICERs of USD$15,608 and USD$15,590 per LYS, from the health system and societal perspective, respectively. In sensitivity analysis, the ICER was most sensitive to discounting of life years saved, variation in case-fatality, disease incidence, vaccine cost, and vaccine effectiveness. The results indicate that universal maternal immunization with Tdap is a cost-effective intervention for preventing

    Temporal lobe epilepsy alters adult neurogenesis. Existing experimental evidence is mainly from chronic models induced by an initial prolonged status epilepticus associated with substantial cell death. In these models, neurogenesis increases after status epilepticus. To test whether status epilepticus is necessary for this increase, we examined precursor cell proliferation and neurogenesis after the onset of spontaneous seizures in a model of temporal lobe epilepsy induced by unilateral intrahippocampal injection of tetanus toxin, which does not cause status or, in most cases, detectable neuronal loss. We found a 4.5 times increase in BrdU labeling (estimating precursor cells proliferating during the 2nd week after injection of toxin and surviving at least up to 7days) in dentate gyri of both injected and contralateral hippocampi of epileptic rats. Radiotelemetry revealed that the rats experienced 112±24 seizures, lasting 88±11s each, over a period of 8.6±1.3days from the first electrographic seizure. On the first day of seizures, their duration was a median of 103s, and the median interictal period was 23min, confirming the absence of experimentally defined status epilepticus. The total increase in cell proliferation/survival was due to significant population expansions of: radial glial-like precursor cells (type I; 7.2×), non-radial type II/III neural precursors in the dentate gyrus stem cell niche (5.6×), and doublecortin-expressing neuroblasts (5.1×). We conclude that repeated spontaneous brief temporal lobe seizures are sufficient to promote increased hippocampal neurogenesis in the absence of status epilepticus. Copyright © 2013 Elsevier Inc.

    In resource-poor settings, cold chain requirements present barriers for vaccine delivery. We evaluated the immunogenicity and safety of tetanus toxoid (TT) vaccine in "Controlled Temperature Chain" (CTC; up to 40 °C for cold chain (SCC; 2-8 °C). Prior to the study, stability parameters of TT-CTC were shown to meet international requirements. A cluster randomized, non-inferiority trial was conducted in Moïssala district, Chad, December 2012-March 2013. Thirty-four included clusters were randomized to CTC or SCC. Women aged 14-49 years, eligible for TT vaccination and with a history of ≤1 TT dose, received two TT doses 4 weeks apart. Participants were blinded to allocation strategy. Tetanus antibody titers were measured using standard ELISA at inclusion and 4 weeks post-TT2. Primary outcome measures were post-vaccination seroconversion and fold-increase in geometric mean concentrations (GMC). Non-inferiority was by seroconversion difference (TTSCC-TTCTC) 95% of participants; upper 95%CI of the difference was 5.6%. Increases in GMC were over 4-fold; upper 95%CI of GMC ratio was 1.36 in the adjusted analysis. Few adverse events were recorded. This study demonstrates the immunogenicity and safety of TT in CTC at cold chain cannot be maintained. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Despite effective infant immunization against pertussis, the disease continues to circulate due to waning immunity. Booster vaccinations against pertussis beyond infancy are widely recommended. In Vietnam, however, no recommendations for pertussis boosters beyond the second year of life exist. This open-label, single-centre study was designed to assess the safety of a single booster dose of reduced-antigen-content-diphtheria-tetanus-acellular-pertussis vaccine (dTpa) in 300 healthy Vietnamese children (mean age 7.9years), who had completed primary vaccination against diphtheria, tetanus and pertussis. Solicited symptoms were recorded for 4days and unsolicited and serious adverse events (SAEs) for 31days post-vaccination. Pain and fatigue were the most common solicited local and general symptoms in 35.0% and 14.0% of children, respectively. Grade 3 swelling occurred in 3 children; no large injection site reactions or SAEs were reported. The dTpa booster vaccine was well tolerated and this study supports its administration in school age Vietnamese children. Copyright © 2016 GSK group of companies. Published by Elsevier Ltd..

    There is a need to use the new technologies to induce immunity with minimum number of vaccination sessions to ensure compliance with reducing cost. To develop single shot vaccines of tetanus, diphtheria and divalent toxoids microsphere's formulations and to induce their immune response after intranasal and subcutaneous administration in mice. The microspheres were prepared using different concentrations of chitosan. Microsphere's morphology, particle size analysis, encapsulation efficiency and antigen integrity were performed and the best formulations were selected for in vitro and in vivo testing in mice. The developed microspheres have a yield percent of 70.3-91.5%. In vitro release of antigens indicated that tetanus release was increased up to 75 and 81% post T5 and TD5 formulations respectively, whereas diphtheria cumulative release increased up to 74 and 69% post D3 and TD5, respectively. Antibody levels produced were lower than that obtained from alum adsorbed vaccine but higher than the minimum level required to induce immunogenicity (>0.01 IU/mL). The subcutaneous route of administration was superior over the intranasal route in producing higher antibody levels. Chitosan microspheres were developed successfully and prove that chitosan represents a good candidate for vaccines delivery.

    Studies from low-income countries have suggested that routine vaccinations may have non-specific effects on child mortality; measles vaccine (MV) is associated with lower mortality and diphtheria-tetanus-pertussis (DTP) with relatively higher mortality. We used data from Navrongo, Ghana, to examine the impact of vaccinations on child mortality. Vaccination status was assessed at the initiation of a trial of vitamin A supplementation and after 12 and 24 months of follow-up. Within the placebo group, we compared the mortality over the first 4 months and the full 2 years of follow-up for different vaccination status groups with different likelihoods of additional vaccinations during follow-up. The frequency of additional vaccinations was assessed among children whose vaccination card was seen at 12 and 24 months of follow-up. Among children with a vaccination card, more than 75% received missing DTP or MV during the first 12 months of follow-up, whereas only 25% received these vaccines among children with no vaccination card at enrollment. Children without a card at enrollment had a significant threefold higher mortality over the 2-year follow-up period than those fully vaccinated. The small group of children with DTP3-4 but no MV at enrollment had lower mortality than children without a card and had the same mortality as fully vaccinated children. In contrast, children with 1-2 DTP doses but no MV had a higher mortality during the first 4 months than children without a card [MRR = 1.65 (0.95, 2.87)]; compared with the fully vaccinated children, they had significantly higher mortality after 4 months [MRR = 2.38 (1.07, 5.30)] and after 2 years [MRR = 2.41 (1.41, 4.15)]. Children with 0-2 DTP doses at enrollment had higher mortality after 4 months (MRR = 1.67 (0.82, 3.43) and after 2 years [MRR = 1.85 (1.16, 2.95)] than children who had all three doses of DTP at enrollment. As hypothesised, DTP vaccination was associated with higher child mortality than measles

    To report the results of an intervention using the 4 Pillars™ Practice Transformation Program (4 Pillars™ Program) to increase adolescent vaccinations including human papillomavirus vaccine (HPV) and influenza vaccines, which remain underutilized in this population. Eleven pediatric and family medicine practices, previously control sites from a randomized controlled cluster trial, with ≥50 adolescent patients participated. The 4 Pillars™ Program was the foundation of the intervention. De-identified demographic, office visit and vaccination data were derived from electronic medical record extractions for patients whose date of birth was 4/1/1997 to 4/1/2004 (ages 11-17years at baseline). Vaccination rates for HPV, influenza, tetanus-pertussis-diphtheria (Tdap) and meningococcal (MenACWY) vaccines were determined for all eligible patients pre- and post intervention (i.e., vaccination rates on 4/1/2015 and 4/30/2016). Among 9473 patients ages 11-17years at baseline (4/1/2015), mean pre-intervention vaccination rates for HPV initiation and completion, meningococcal, Tdap and influenza vaccines were below national levels. Rates increased significantly post intervention (P<0.001) for HPV initiation which increased 17.1 percentage points (PP) from 51.4%; HPV completion increased 14.8PP from 30.7%, meningococcal vaccine uptake increased 16.6PP from 79.1%, Tdap vaccine uptake increased 14.6PP from 76.9%. Influenza vaccine uptake did not increase significantly (2.3PP from 40.1%). In the regression using generalized estimating equations, odds of vaccination were higher for younger, non-white adolescents for all vaccines; being in a smaller practice decreased the odds of Tdap vaccination but increased the odds of influenza vaccination. Clinically and statistically significant improvements in HPV series initiation and completion, and meningococcal and Tdap vaccinations were observed in primary care practices implementing the 4 Pillars™ Practice Transformation Program

    Although 93% of 12- to 23-month-old children in India receive at least one vaccine, typically Bacillus Calmette-Guérin, only 75% complete the recommended three doses of diphtheria-pertussis-tetanus (DPT, also referred to as DTP) vaccine. Determinants can be different for nonvaccination and dropout but have not been examined in earlier studies. We use the three-dose DPT series as a proxy for the full sequence of recommended childhood vaccines and examine the determinants of DPT nonvaccination and dropout between doses 1 and 3. We analyzed data on 75,728 6- to 23-month-old children in villages across India to study demand- and supply-side factors determining nonvaccination with DPT and dropout between DPT doses 1 and 3, using a multilevel approach. Data come from the District Level Household and Facility Survey 3 (2007-08). Individual- and household-level factors were associated with both DPT nonvaccination and dropout between doses 1 and 3. Children whose mothers had no schooling were 2.3 times more likely not to receive any DPT vaccination and 1.5 times more likely to drop out between DPT doses 1 and 3, compared with children whose mothers had 10 or more years of schooling. Although supply-side factors related to availability of public health facilities and immunization-related health workers in villages were not correlated with dropout between DPT doses 1 and 3, children in districts where 46% or more villages had a healthcare subcentre were 1.5 times more likely to receive at least one dose of DPT vaccine compared with children in districts where 30% or fewer villages had subcentres. Nonvaccination with DPT in India is influenced by village- and district-level contextual factors over and above individuals' background characteristics. Dropout between DPT doses 1 and 3 is associated more strongly with demand-side factors than with village- and district-level supply-side factors. Copyright © 2017 The Authors.

    Vietnam plans to replace the routine childhood diphtheria, pertussis and tetanus combination (DPT) vaccine with a pentavalent vaccine. The present study was performed to assess the immunogenicity and safety of the combined diphtheria, tetanus, whole-cell pertussis, hepatitis B (HepB), and Haemophilus influenzae type b (Hib) (DTwP-HepB-Hib) Quinvaxem® vaccine in children. A total of 131 infants received the Quinvaxem® vaccine at 2, 3 and 4 months. Antibody levels were measured at baseline, at one month after the third injection and one year after the first injection. Seroprotection rates were high for each vaccine antigen at one month after the third dose: 93.1% for diphtheria, 98.5% for tetanus, 99.2% for pertussis (seroconversion rate), 93.1% for HepB, and 100% for Hib (anti-PRP ≥ 0.15 µg/ml). The rate of children with protective antibodies persisting at one year after the first dose was 88.4% for diphtheria, 49.6% for pertussis, 82.2% for tetanus, 76.7% for HepB and 97.7% for Hib (anti-PRP ≥ 0.15 µg/ml). The Quinvaxem® vaccine was well tolerated and has a low rate of adverse events. Quinvaxem® given at 2, 3 and 4 months of age was immunogenic and safe for primary immunization among infants in Vietnam.

    This phase II clinical trial was conducted to compare the immunogenicity and safety of a newly developed tetanus-reduced diphtheria (Td) vaccine (GC1107-T5.0 and GC1107-T7.5) and control vaccine. This study was also performed to select the proper dose of tetanus toxoid in the new Td vaccines. Healthy adolescents aged between 11 and 12 yr participated in this study. A total of 130 subjects (44 GC1107-T5.0, 42 GC1107-T7.5 and 44 control vaccine) completed a single dose of vaccination. Blood samples were collected from the subjects before and 4 weeks after the vaccination. In this study, all subjects (100%) in both GC1107-T5.0 and GC1107-T7.5 groups showed seroprotective antibody levels (≥ 0.1 U/mL) against diphtheria or tetanus toxoids. After the vaccination, the geometric mean titer (GMT) against diphtheria was significantly higher in Group GC1107-T5.0 (6.53) and GC1107-T7.5 (6.11) than in the control group (3.96). The GMT against tetanus was 18.6 in Group GC1107-T5.0, 19.94 in GC1107-T7.5 and 19.01 in the control group after the vaccination. In this study, the rates of local adverse reactions were 67.3% and 59.1% in GC1107-T5.0 and GC1107-7.5, respectively. No significant differences in the number of adverse reactions, prevalence and degree of severity of the solicited and unsolicited adverse reactions were observed among the three groups. Thus, both newly developed Td vaccines appear to be safe and show good immunogenicity. GC1107-T5.0, which contains relatively small amounts of tetanus toxoid, has been selected for a phase III clinical trial.

    Full Text Available In many regions of sub-Saharan Africa, both HIV and helminth infections are prevalent. HIV-1 (human immunodeficiency virus type 1 and helminth infections can both compromise immune responses in humans. To determine whether the presence of helminth infection or the treatment of helminth infection alters unstimulated vaccine responses among HIV-1 infected individuals, we conducted two nested serologic studies. Blood samples were collected for HIV disease monitoring and vaccine-specific serologic assays, while stool was evaluated by direct microscopy methods. We compared antibody responses to measles and tetanus vaccines in helminth-infected (Ascaris, Trichuris, hookworm and/or Schistosoma mansoni and uninfected adults 18 years and older (n = 100. We also compared measles and tetanus antibody responses in Ascaris only-infected adults receiving 400 mg albendazole daily for 3 days (n = 16 vs. placebo (n = 19 in a separate study. In both cohorts, over 70% of participants had measles and tetanus responses above the protective threshold. Prevalence of measles responses were similar between helminth-infected and uninfected individuals (82%, 95% CI: 71–93% vs 72%, 95% CI: 59–85%, as well as log10 tetanus antibody levels (−0.133 IU/mL vs −0.190 IU/mL, p > 0.05, and did not differ by helminth species. In the Ascaris-infected cohort, changes in measles responses and tetanus responses did not differ between those who received anthelminthic vs. placebo (p > 0.05 for both. In these studies, neither helminth infection, nor deworming, appeared to affect previously administered vaccine responsiveness in HIV-1 infected, ART naïve, adults in Kenya.

    The meningococcal groups C and Y and Haemophilus b (Hib) tetanus toxoid conjugate vaccine (HibMenCY-TT) contains Neisseria meningitidis serogroup C and Y capsular polysaccharide antigens, and Hib capsular polysaccharide [polyribosyl-ribitol-phosphate (PRP)]. The HibMenCY-TT vaccine is available in the USA for use as active immunization to prevent invasive disease caused by N. meningitidis serogroups C (MenC) and Y (MenY), and Hib in children 6 weeks-18 months of age. HibMenCY-TT is the first meningococcal vaccine available for use in the USA that can be administered to infants as young as 6 weeks of age. In a randomized, controlled, phase III clinical trial, the HibMenCY-TT vaccine, administered to infants at 2, 4, 6 and 12-15 months of age, was immunogenic against MenC and MenY, and met the prespecified criteria for immunogenicity. Anti-PRP antibodies, which have been shown to correlate with protection against Hib invasive disease, were also induced in the infants who received the HibMenCY-TT vaccine, with induced levels of this antibody noninferior to those occurring in the control group of infants who received a Hib tetanus toxoid conjugate vaccine at 2, 4, and 6 months and a single dose of Hib conjugated to N. meningitidis outer membrane protein at 12-15 months. In several randomized, controlled clinical trials, HibMenCY-TT was coadministered with vaccines that are routinely administered to infants and toddlers in the USA. These vaccines included: diphtheria and tetanus toxoids and acellular pertussis adsorbed, hepatitis B (recombinant) and inactivated poliovirus vaccine combined; 7-valent Streptococcus pneumoniae polysaccharide conjugate vaccine; measles, mumps and rubella vaccine; and varicella vaccine. Coadministration of these vaccines did not interfere with the immunogenicity of the HibMenCY-TT vaccine. Similarly, immune responses to the coadministered vaccines were not affected by the HibMenCY-TT vaccine. The tolerability profile of the Hib

    Full Text Available Alcohol intoxication and ischemic injury of skeletal muscles often accompany each other. It is shown that patients hospitalized with chronic alcoholism develop muscle fatigue. Skeletal muscle dysfunction in alcohol-dependent patients is caused by ethanol-associated myofibrillar atrophy and metabolic disbalance, while compression-ischemic lesions result from unconsciousness of the patient, in case of taking the critical alcohol dose. Therefore, the aim of this study is to discover typical m. gastrocnemius (cap. med. tetanic kinetics changes in alcohol intoxicated rats with experimentally induced vascular ischemia of hindlimb muscles under conditions of low-frequency progressive muscle fatigue. Experiments were carried out on 10 young male Wistar rats (149.5 ± 5.8 g kept under standard vivarium conditions and diet. The investigation was conducted in two phases: chronic (30 days and acute (3 hours experiment. All surgical procedures were carried out aseptically under general anesthesia. Ishemic m. gastrocnemius (cap. med. tetanic kinetic changes and force productivity in alcohol intoxicated rats were investigated in the isometric mode, with direct electrical stimulation. The fatigue of m. gastrocnemius (cap. med. was evaluated by three characteristic criteria: the first sag effect, the secondary force rise, the second sag effect. There have been 10 similar experiments: 5 series in each study group with 10 tetanic runs in each series. The highest amplitude of the native m. gastrocnemius (cap. med. tetanus relative to isoline was taken as 100% force response. The same pattern of m. gastrocnemius (cap. med. low-frequency fatigue development was found in both rat groups under study. It is evidenced by the absence of substantial m. gastrocnemius (cap. med. tetanus kinetics differences in alcohol intoxicated rats, compared with non-alcohol intoxicated rats during fatigue test. However, the appreciable m. gastrocnemius (cap. med. tetanic force reduction

    Vaccination with whole-cell pertussis vaccine carries an increased risk of febrile seizures, but whether this risk applies to the acellular pertussis vaccine is not known. In Denmark, acellular pertussis vaccine has been included in the combined diphtheria-tetanus toxoids-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b (DTaP-IPV-Hib) vaccine since September 2002. To estimate the risk of febrile seizures and epilepsy after DTaP-IPV-Hib vaccination given at 3, 5, and 12 months. A population-based cohort study of 378,834 children who were born in Denmark between January 1, 2003, and December 31, 2008, and followed up through December 31, 2009; and a self-controlled case series (SCCS) study based on children with febrile seizures during follow-up of the cohort. Hazard ratio (HR) of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination and HR of epilepsy after first vaccination in the cohort study. Relative incidence of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination in the SCCS study. A total of 7811 children were diagnosed with febrile seizures before 18 months, of whom 17 were diagnosed within 0 to 7 days after the first (incidence rate, 0.8 per 100,000 person-days), 32 children after the second (1.3 per 100,000 person-days), and 201 children after the third (8.5 per 100,000 person-days) vaccinations. Overall, children did not have higher risks of febrile seizures during the 0 to 7 days after the 3 vaccinations vs a reference cohort of children who were not within 0 to 7 days of vaccination. However, a higher risk of febrile seizures was found on the day of the first (HR, 6.02; 95% CI, 2.86-12.65) and on the day of the second (HR, 3.94; 95% CI, 2.18-7.10), but not on the day of the third vaccination (HR, 1.07; 95% CI, 0.73-1.57) vs the reference cohort. On the day of vaccination, 9 children were diagnosed with febrile seizures after the first (5.5 per 100,000 person-days), 12

    Full Text Available The article summarizes data on methods and opportunities of frequently ailing children rehabilitation. Authors mark a leading role of vaccination against pneumotropic infections. Questions of successful interaction between doctor and frequently ailing child’s parents are highlighted. The observation of 94 children 3 months — 3 years old (patients had different types of initial immune insuffiiency, neurological pathology, recurrent obstructive bronchitis, or were included in group of frequently ailing children vaccinated with Pentaxim was performed. 94% of children showed asymptomatic postvaccinal period. Fever up to 39°C occurred in 2.3% of patients. Local reactions (diameter was not over 3–5 cm developed in 1.7% of children. There was no any case of postvaccinal complication. Evaluation of vaccine’s reactogenity proves its safety and reasonability in immunization against pertussis, diphtheria, tetanus, poliomyelitis, Haemophilis influenzae type b in children of different health state including those with concomitant diseases.

  14. Potential protective immunogenicity of tetanus toxoid, diphtheria toxoid and Cross Reacting Material 197 (CRM197) when used as carrier proteins in glycoconjugates.

    When tetanus toxoid (TT), diphtheria toxoid (DT) or Cross Reacting Material 197 (CRM197), a non-toxic diphtheria toxin mutant protein, are used as carrier proteins in glycoconjugate vaccines, these carriers induce a protein specific antibody response as measured by in vitro assays. Here, it was evaluated whether or not glycoconjugates based on TT, DT or CRM197 can induce a protective immune response as measured by potency tests according to the European Pharmacopoeia. It could be shown, that the conjugate carriers TT and DT can induce a protective immune response against a lethal challenge by toxins in animals, while glycoconjugates based on CRM197 failed to induce a protective immune response. Opportunities for new applications of glycoconjugates are discussed.

    Rotavirus is the leading cause of severe acute gastroenteritis in infants and young children. Most children are infected with rotavirus, and the health and economic burdens of rotavirus gastroenteritis on healthcare systems and families are considerable. In 2012 pentavalent rotavirus vaccine (RV5) and diphtheria, tetanus, acellular pertussis and inactivated poliovirus vaccine derived from Sabin strains (DTaP-sIPV) were licensed in Japan. We examined the immunogenicity and safety of DTaP-sIPV when administrated concomitantly with RV5 in Japanese infants. A total of 192 infants 6 to 11 weeks of age randomized to Group 1 (N = 96) received DTaP-sIPV and RV5 concomitantly, and Group 2 (N = 96) received DTaP-sIPV and RV5 separately. Antibody titer to diphtheria toxin, pertussis antigens (PT and FHA), tetanus toxin, and poliovirus type 1, 2, and 3 were measured at 4 to 6 weeks following 3-doses of DTaP-sIPV. Seroprotection rates for all components of DTaP-sIPV were 100% in both groups, and the geometric mean titers for DTaP-sIPV in Group 1 were comparable to Group 2. Incidence of systemic AEs (including diarrhea, vomiting, fever, and nasopharyngitis) were lower in Group 1 than in Group 2. All vaccine-related AEs were mild or moderate in intensity. There were no vaccine-related serious AEs, no deaths, and no cases of intussusception during the study. Concomitant administration of DTaP-sIPV and RV5 induced satisfactory immune responses to DTaP-sIPV and acceptable safety profile. The administration of DTaP-sIPV given concomitantly with RV5 is expected to facilitate compliance with the vaccination schedule and improve vaccine coverage in Japanese infants.

    The recent increase of pertussis in young adults in Japan is hypothesized to be due in part to waning protection from the acellular pertussis vaccine. While a booster immunization may prevent an epidemic of pertussis among these young adults, little is known about the safety and immunogenicity of such a booster with the diphtheria, tetanus, and acellular pertussis vaccine (DTaP), which is currently available in Japan. One hundred and eleven medical students with a mean age of 19.4 years were randomly divided into 2 groups of 55 and 56 subjects and received, respectively, 0.2 or 0.5 ml of DTaP. Immunogenicity was assessed by performing the immunoassay using serum, and the geometric mean concentration (GMC), GMC ratio (GMCR), seropositive rate, and booster response rate were calculated. Adverse reactions and adverse events were monitored for 7 days after vaccination. After booster vaccination in the two groups, significant increases were found in the antibodies against pertussis toxin, filamentous hemagglutinin, diphtheria toxoid, and tetanus toxoid, and the booster response rates for all subjects reached 100%. The GMCs and GMCRs against all antigens were significantly higher in the 0.5-ml group than in the 0.2-ml group. No serious adverse events were observed. Frequencies of local reactions were similar in the 2 groups, although the frequency of severe local swelling was significantly higher in the 0.5-ml group. These data support the acceptability of booster immunization using both 0.2 and 0.5 ml of DTaP for young adults for controlling pertussis.

    The organizational role of pubertal androgen receptor (AR) activation in synaptic plasticity in hippocampal CA1 and in social memory was assessed. Earlier data suggest pubertal testosterone reduces adult hippocampal synaptic plasticity. Four groups were created following gonadectomy at the onset of puberty: rats given testosterone; rats given testosterone but with the AR antagonist flutamide, present during puberty; rats given testosterone at the end of puberty; and rats given cholesterol at the end of puberty. A tetanus normally inducing long-term potentiation (LTP) was used to stimulate CA1 in the urethane-anesthetized adults during the dark phase of their cycle. Social memory was assessed prior to electrophysiology. Social memory for a juvenile rat at 120 min was seen only in rats not exposed to AR activation during puberty. Pubertal AR activation may induce the reduced social memory of male rats. Early CA1 LTP occurred following tetanus in rats with no pubertal testosterone. Short-term potentiation occurred in rats exposed to pubertal testosterone. Unexpectedly, rats with pubertal AR activation developed long-term depression (LTD). The same pattern was seen in normal male rats. Lack of LTP during the dark phase is consistent with other data on circadian modulation of CA1 LTP. No correlations were seen among social memory scores and CA1 plasticity measures. These data argue for two organizational effects of pubertal testosterone: (1) CA1 synaptic plasticity shifts away from potentiation toward depression; (2) social memory is reduced. Enduring effects of pubertal androgen on limbic circuits may contribute to reorganized behaviors in the postpubertal period.

    Full Text Available Serosurveillance and seroprevalence studies are an essential tool to monitor vaccine-preventable diseases. We have developed a magnetic bead-based pentaplex immunoassay (MIA for the simultaneous detection of IgG antibodies against diphtheria toxin (DT, tetanus toxin (TT, pertussis toxin (PT, filamentous hemagglutinin (FHA and pertactin (Prn. The in-house pentaplex MIA showed a good correlation with commercial ELISAs with correlation coefficients between 0.89 for PT and 0.98 for TT. Intra- and inter-assay variability was <10%. A total of 670 anonymized serum samples collected in 2012 in Belgian adults (ages 20–29.9 years were analyzed. Geometric mean concentrations (GMC were 0.2 (0.13–0.29 IU/mL for DT, 0.63 (0.45–0.82 IU/mL for TT, 3.9 (2.6–5.8 IU/mL for PT, 16.3 (11.7–22.7 IU/mL for FHA and 15.4 (10.1–23.6 IU/mL for Prn. Antibody concentrations were below the protective level of 0.1 IU/mL in 26.4% of the sera for DT and in 8.6% of the sera for TT. Anti-PT IgG concentrations indicative of recent pertussis infection (>125 IU/mL were detected in 1.2% of the subjects. High anti-PT antibodies were not correlated with high antibodies against any of the four other vaccine antigens. This pentaplex MIA will be used for a new large-scale Belgian serosurveillance/seroprevalence study of diphtheria, tetanus and pertussis.

    Detection of anti-tetanus antibody levels is necessary for both determination of the immune status of individuals and also for planning preventive measures. ELISA is the preferred test among in vitro tests however it can be affected by the cross reacting antibodies. A previously developed in-house ELISA test was found not reliable for the antibody levels ≤1.0IU/ml. A new method was developed to detect low antibody levels correctly. The aim of the present study was to compare the results of the newly developed in-house biotin-avidin tetanus IgG ELISA test with the in vivo mouse neutralization test, for the antibody levels ≤1.0IU/ml. A total of 54 serum samples with the antibody levels of three different levels, =0.01IU/ml, 0.01-0.1IU/ml, 0.1-1IU/ml, which were detected by in vivo mouse neutralization test were studied by the newly developed in-house biotin-avidin tetanus IgG ELISA test. Test was validated by using five different concentrations (0.01IU/ml, 0.06IU/ml, 0.2IU/ml, 0.5IU/ml, 1.0IU/ml). A statistically significant correlation (r 2 =0.9967 p=0,001) between in vivo mouse neutralization test and in-house biotin-avidin tetanus IgG ELISA test, was observed. For the tested concentrations intra-assay, inter-assay, accuracy, sensitivity, specificity and coefficients of variations were determined as ≤15%. In-house biotin-avidin tetanus IgG ELISA test can be an alternative method to in vivo mouse neutralization method for the detection of levels ≤1.0IU/ml. By using in-house biotin-avidin tetanus IgG ELISA test, individuals with non protective levels, will be reliably detected. Copyright © 2017. Published by Elsevier B.V.

    Time-resolved x-ray diffraction studies have been made on the 5.9- and 5.1-nm actin layer lines from frog skeletal muscles during an isometric tetanus at 6 degrees C, using synchrotron radiation. The integrated intensities of these actin layer lines were found to increase during a tetanus by 30-50% for the 5.9-nm reflection and approximately 70% for the 5.1-nm reflection of the resting values. The intensity increase of both reflections was greater than that taking place in the transition from rest to rigor state. The intensity change of the 5.9-nm reflection preceded those of the myosin 42.9-nm off-meridional reflection and of the equatorial reflections, as well as the isometric tension development. The intensity profile of the 5.9-nm layer line during contraction was found to be different from that observed in the rigor state

    The recombinant C-terminal domain of tetanus toxin (Hc-TeTx) is a new non-toxic peptide of the tetanus toxin that exerts a protective action against glutamate excitotoxicity in motoneurons. Moreover, its efficacy as a neuroprotective agent has been demonstrated in several animal models of neurodegeneration. The eleven amino acids in the β amyloid peptide (Aβ25-35) mimic the toxic effects of the full β amyloid peptide (Aβ1-42), causing the impairment of the cholinergic system in the medial septum (MS) which, in turn, alters the septo-hippocampal pathway and leads to learning and memory impairments. The aim of this study was to examine the neuroprotective effects of the Hc-TeTx fragment against cholinotoxicity. The Hc-TeTx fragment (100 ng) was injected into the rats intercranially, with the Aβ(25-35) (2 μg) then injected into their MS. The animals were tested for spatial learning and memory in the eight-arm radial maze. The brains were removed to assess cholinergic markers, such as choline acetyltransferase (ChAT) and acetylcholinesterase (AChE), and to explore neurodegeneration in the MS and hippocampus, using amino-cupric silver and H&E staining. Finally, capase-3, a marker of apoptosis, was examined in the MS. Our results clearly demonstrate that the application of Hc-TeTx prevents the loss of cholinergic markers (ChAT and AChE), the activation of capase-3, and neurodegeneration in the MS and the CA1 and CA3 subfields of the hippocampus. All these improvements were reflected in spatial learning and memory performance, and were significantly higher compared with animals treated with Aβ(25-35). Interestingly, the single administration of Hc-TeTx into the MS modified the ChAT and AChE expression that affect cognitive processes, without inducing neurodegeneration or an increase in capase-3 expression in the MS and hippocampus. In summary, our findings suggest that the recombinant Hc-TeTx fragment offers effective protection for the septo-hippocampal pathway

    Regular booster vaccination might be necessary throughout life to protect against pertussis infection. Nevertheless the duration of protection after booster vaccination remains unclear. In this study, antibody persistence up to 10 years after previous vaccination of adolescents (N=478) with combined reduced-antigen-content diphtheria-tetanus-acellular pertussis vaccine (dTpa, Boostrix™, GlaxoSmithKline Belgium) containing 0.5mg, 0.3mg or 0.133mg of aluminium was assessed. The immunogenicity, reactogenicity and safety of a decennial booster dTpa dose were also investigated. Young adults vaccinated as adolescents in the initial booster study were invited to participate in an assessment of antibody persistence at years 8.5 and 10, and to receive a dTpa booster dose at year 10 with immunogenicity assessment one month later. Those who originally received the 0.5mg or 0.3mg formulations received the same vaccine at year 10. Those in the 0.133mg group received the 0.5mg formulation. Reactogenicity and safety endpoints were captured until 30 days after booster vaccination. Prior to the decennial booster at year 8.5 and year 10, all participants had seroprotective antibodies for diphtheria (ELISA or neutralisation assay) and tetanus. At least 77.8% were seropositive for anti-pertussis toxin (PT) antibodies at year 8.5 and 82.8% at year 10. All participants were seropositive for antibodies for filamentous haemagglutinin and pertactin at both time points. The decennial booster dose induced robust increases in antibody GMCs to all antigens. The post-booster anti-PT geometric mean concentration was 82.5EL.U/ml (95%CI 67.0-101.6) and 124.0 (103.5-148.5) in the 0.3mg and 0.5mg groups, respectively. The reactogenicity and safety profile of the decennial booster dose was consistent with the known safety profile of dTpa. No serious adverse events were reported. Decennial booster vaccination with either of the two licensed formulations of dTpa was highly immunogenic and well

    Phase II and III clinical studies were conducted to evaluate immunogenicity and safety of a novel DTaP-IPV vaccine consisting of Sabin inactivated poliovirus vaccine (sIPV) and diphtheria-tetanus-acellular pertussis vaccine (DTaP). A Phase II study was conducted in 104 healthy infants using Formulation H of the DTaP-sIPV vaccine containing high-dose sIPV (3, 100, and 100 D-antigen units for types 1, 2, and 3, respectively), and Formulations M and L, containing half and one-fourth of the sIPV in Formulation H, respectively. Each formulation was administered 3 times for primary immunization and once for booster immunization. A Phase III study was conducted in 342 healthy infants who received either Formulation M + oral polio vaccine (OPV) placebo or DTaP + OPV. The OPV or OPV placebo was orally administered twice between primary and booster immunizations. Formulation M was selected as the optimum dose. In the Phase III study, the seropositive rate was 100% for all Sabin strains after primary immunization, and the neutralizing antibody titer after booster immunization was higher than in the control group (DTaP + OPV). All adverse reactions were clinically acceptable. DTaP-sIPV was shown to be a safe and immunogenic vaccine.

    Assessing the ability of current equine influenza vaccines to provide cross-protection against emerging strains is important. Horses not vaccinated previously and seronegative for equine influenza based on haemagglutination inhibition (HI) assay were assigned at random to vaccinated (n=7) or non-vaccinated (control, n=5) groups. Vaccination was performed twice four weeks apart with a 1 ml influenza subunit (A/eq/Prague/1/56, A/eq/Newmarket/1/93, A/eq/Newmarket/2/93), tetanus toxoid vaccine with Matrix-C adjuvant (EquilisPrequenza Te). All the horses were challenged individually by aerosol with A/eq/Richmond/1/07 three weeks after the second vaccination. Rectal temperature, clinical signs, serology and virus excretion were monitored for 14 days after challenge. There was no pain at the injection site or increases in rectal temperature following vaccination. Increases in rectal temperature and characteristic clinical signs were recorded in the control horses. Clinical signs were minimal in vaccinated horses. Clinical (P=0.0345) and total clinical scores (P=0.0180) were significantly lower in the vaccinated than in the control horses. Vaccination had a significant effect on indicators of viraemia - the extent (P=0.0006) and duration (P=horse was positive or negative for virus excretion during the study. Further research is needed to fully understand the specific properties of this vaccine that may contribute to its cross-protective capacity. British Veterinary Association.

    The quadrivalent meningococcal conjugate vaccine (MenACWY-CRM) has been introduced for military recruits in Korea since 2012. This study was performed to evaluate the immunogenicity of MenACWY-CRM in Korean military recruits. In addition, the influence of tetanus-diphtheria toxoids (Td) vaccination on the vaccine response to MenACWY-CRM was analyzed. A total of 75 military recruits were enrolled. Among them, 18 received a dose of MenACWY-CRM only (group 1), and 57 received Td three days before MenACWY-CRM immunization (group 2). The immunogenicity of MenACWY-CRM was compared between the two groups. The serum bactericidal activity with baby rabbit complement was measured before and three weeks after immunization against serogroups A, C, W-135, and Y. The geometric mean titers (GMTs) against four serogroups were significantly increased in both groups after immunization. Compared to group 2, group 1 exhibited significantly higher vaccine responses in several aspects: post-immune GMTs against serogroup A and C, seroresponse rates against serogroup A, and a fold increases of titers against serogroup A, C, and Y. MenACWY-CRM was immunogenic against all vaccine-serogroups in Korean military recruits. Vaccine response to MenACWY-CRM was influenced by Td administered three days earlier.

    Full Text Available Introduction: GP63 is a major surface protease of Leishmania promastigotes that plays an important role in its virulance. As GP63 on its own can not develop an effective protection against leishmaniasis, the goal of this study was to evaluate the protective effect of GP63 conjugated with tetanus toxoid (TT and Vitamin D3 in susceptible BALB/c mice against cutaneous leishmaniasis. Methods: This study was a basic-applied experimental study performed in Tarbiat Modarres University from September 2002 to April 2005. Cloned virulant Leishmania (L. major [MRHO / IR / 75 / ER] strain was cultured and 5109 cells were harvested. GP63 Molecule was purified and conjugated with TT and conjugated molecule was used for immunization of 8 groups of female BALB/c mice. Results: Results showed that the group of mice receiving conjugated molecule with Vitamin D3 had significant differences from other groups regarding lesion progression (P0.05. The culture of spleen cells showed that the disease did not become systemic in this group. Conclusion: Conjugation of GP63 with TT strengthens cell immunity and its use along with vitamin D3 provokes macrophages activity. This basis can be used for production of an appropriate preparation for protection against Leishmaniasis.

    We have previously shown that in mice, diphtheria-tetanus-acellular pertussis (DTaP) vaccination before Bordetella pertussis infection resulted in, besides effective clearance, immediate hypersensitivity (lung eosinophilia, increased total serum immunoglobulin E [IgE], and increased ex vivo Th2 cytokine production by cells from the bronchial lymph nodes). To better appreciate the extent of these findings, we measured DTaP vaccination effects in the local lymph node assay (LLNA) and an ovalbumin (OVA) lung allergy model. In the LLNA, mice were vaccinated or adjuvant treated before being sensitized with trimellitic anhydride (TMA; inducing a Th2-directed response) and dinitrochlorobenzene (DNCB; inducing a Th1-directed response). Compared to the adjuvant-treated controls, the vaccinated mice showed a decreased response to TMA and (to a much lesser extent) an increased response to DNCB. The decreased response to TMA coincided with increased transforming growth factor β levels. With the exception of filamentous hemagglutinin, all vaccine constituents contributed to the decreased response to TMA. In the lung allergy model, sensitization induced OVA-specific IgE, lung pathology (peribronchiolitis, perivasculitis, and hypertrophy of the bronchiolar mucus cells) and increased the number of eosinophils, lymphocytes, and neutrophils in the bronchoalveolar lavage fluid. Vaccination failed to modulate these parameters. In conclusion, although DTaP vaccination may affect the LLNA response, we found no evidence of an effect on lung allergy. PMID:17202304

    Study safety, reactogenicity and immunologic effectiveness of a national combined vaccine against diphtheria, pertussis (acellular component), tetanus, hepatitis B and Hib-infection during immunization of volunteers aged 18-60 years. The study was carried out in accordance with ethical standards and requirements, regulated by Helsinki declaration and Good clinical practice (ICHGCP). In a simple non-randomized clinical trial 20 adult volunteers took part, the mean age of those was 46.9 years. Registered: post-vaccination reactions (both local and systemic) were mild and of moderate degree of severity, stopped independently after 2-3 days without administration of drug treatment. Postvaccinal complications were not noted. Parameters of general and biochemical analysis of blood, urine, IgE content in dynamics of immunization were within normal limits. A single administration of aAPDT--HepB+Hib to individuals aged 18-60 years resulted in development of antibodies against all the components of the preparation. Seroconversion factor fluctuated from 6.9 to 53.5: The results obtained allow to recommend the vaccine for evaluation of its safety, reactogenicity, immunologic and prophylaxis effectiveness in randomized clinical observation trials in children.

    Full Text Available The reduction of brain amyloid beta (Aβ peptides by anti-Aβ antibodies is one of the possible therapies for Alzheimer’s disease. We previously reported that the Aβ peptide vaccine including the T-cell epitope of diphtheria-tetanus combined toxoid (DT induced anti-Aβ antibodies, and the prior immunization with conventional DT vaccine enhanced the immunogenicity of the peptide. Cynomolgus monkeys were given the peptide vaccine subcutaneously in combination with the prior DT vaccination. Vaccination with a similar regimen was also performed on guinea pigs. The peptide vaccine induced anti-Aβ antibodies in cynomolgus monkeys and guinea pigs without chemical adjuvants, and excessive immune responses were not observed. Those antibodies could preferentially recognize Aβ40, and Aβ42 compared to Aβ fibrils. The levels of serum anti-Aβ antibodies and plasma Aβ peptides increased in both animals and decreased the brain Aβ40 level of guinea pigs. The peptide vaccine could induce a similar binding profile of anti-Aβ antibodies in cynomolgus monkeys and guinea pigs. The peptide vaccination could be expected to reduce the brain Aβ peptides and their toxic effects via clearance of Aβ peptides by generated antibodies.

    ABSTRACT Safety and immunogenicity of 2 investigational formulations of diphtheria, tetanus and Haemophilus influenzae type b antigens of the combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliomyelitis-Hib vaccine (DTPa-HBV-IPV/Hib) were evaluated in a Primary (NCT01248884) and a Booster vaccination (NCT01453998) study. In the Primary study, 721 healthy infants (randomized 1:1:1) received 3 doses of DTPa-HBV-IPV/Hib formulation A (DATAPa-HBV-IPV/Hib), or B (DBTBPa-HBV-IPV/Hib) or the licensed DTPa-HBV-IPV/Hib vaccine (Infanrix hexa, GSK; control group) at 2, 3, 4 months of age. Infants were planned to receive a booster dose at 12–15 months of age with the same formulation received in the Primary study; however, following high incidence of fever associated with the investigational formulations in the Primary study, the Booster study protocol was amended and all infants yet to receive a booster dose (N = 385) received the licensed vaccine. In the Primary study, non-inferiority of 3-dose vaccination with investigational formulations compared with the licensed vaccine was not demonstrated due to anti-pertactin failing to meet the non-inferiority criterion. Post-primary vaccination, most infants had seroprotective levels of anti-diphtheria (100% of infants), anti-tetanus antigens (100%), against hepatitis B (≥ 97.5% across groups), polyribosyl-ribitol-phosphate (≥ 88.0%) and poliovirus types 1–3 (≥ 90.5%). Seropositivity rates for each pertussis antigen were 100% in all groups. Higher incidence of fever (> 38°C) was reported in infants receiving the investigational formulations (Primary study: 75.0% [A] and 72.1% [B] vs 58.8% [control]; Booster study, before amendment: 49.4% and 46.6% vs 37.4%, respectively). The development of the investigational formulations was not further pursued. PMID:28340322

    Full Text Available Spinal muscular atrophy (SMA is a hereditary childhood disease that causes paralysis and progressive degeneration of skeletal muscles and spinal motor neurons. SMA is associated with reduced levels of full-length Survival of Motor Neuron (SMN protein, due to mutations in the Survival of Motor Neuron 1 gene. Nowadays there are no effective therapies available to treat patients with SMA, so our aim was to test whether the non-toxic carboxy-terminal fragment of tetanus toxin heavy chain (TTC, which exhibits neurotrophic properties, might have a therapeutic role or benefit in SMA. In this manuscript, we have demonstrated that TTC enhance the SMN expression in motor neurons in vitro and evaluated the effect of intramuscular injection of TTC-encoding plasmid in the spinal cord and the skeletal muscle of SMNdelta7 mice. For this purpose, we studied the weight and the survival time, as well as, the survival and cell death pathways and muscular atrophy. Our results showed that TTC treatment reduced the expression of autophagy markers (Becn1, Atg5, Lc3 and p62 and pro-apoptotic genes such as Bax and Casp3 in spinal cord. In skeletal muscle, TTC was able to downregulate the expression of the main marker of autophagy, Lc3, to wild type levels and the expression of the apoptosis effector protein, Casp3. Regarding the genes related to muscular atrophy (Ankrd1, Calm1, Col19a1, Fbox32, Mt2, Myod1, NogoA, Pax7, Rrad, and Sln, TTC suggest a compensatory effect for muscle damage response, diminished oxidative stress and modulated calcium homeostasis. These preliminary findings suggest the need for further experiments to depth study the effect of TTC in SMA disease.

    In October 2011, the Advisory Committee on Immunization Practices (ACIP) issued updated recommendations that all pregnant women routinely receive a dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine. We characterized reports to the Vaccine Adverse Event Reporting System (VAERS) in pregnant women who received Tdap after this updated recommendation (2011-2015) and compared the pattern of adverse events (AEs) with the period before the updated recommendation (2005-2010). We searched the VAERS database for reports of AEs in pregnant women who received Tdap vaccine after the routine recommendation (11/01/2011-6/30/2015) and compared it to published data before the routine Tdap recommendation (01/01/2005-06/30/2010). We conducted clinical review of reports and available medical records. The clinical pattern of reports in the post-recommendation period was compared with the pattern before the routine Tdap recommendation. We found 392 reports of Tdap vaccination after the routine recommendation. One neonatal death but no maternal deaths were reported. No maternal or neonatal deaths were reported before the recommendation. We observed an increase in proportion of reports for stillbirths (1.5-2.8%) and injection site reactions/arm pain (4.5-11.9%) after the recommendation compared to the period before the routine recommendation for Tdap during pregnancy. We noted a decrease in reports of spontaneous abortion (16.7-1%). After the 2011 Tdap recommendation, in most reports, vaccination (79%) occurred during the third trimester compared to 4% before the 2011 Tdap recommendation. Twenty-six reports of repeat Tdap were received in VAERS; 13 did not report an AE. One medical facility accounted for 27% of all submitted reports. No new or unexpected vaccine AEs were noted among pregnant women who received Tdap after routine recommendations for maternal Tdap vaccination. Changes in reporting patterns would be expected, given the broader use of

    Maternal antibodies induced by vaccination during pregnancy cross the placental barrier and can close the susceptibility gap to pertussis in young infants up to the start of primary immunization. As not only the quantity but also the quality of circulating antibodies is important for protection, we assessed whether maternal immunization affects the avidity of infant vaccine-induced IgG antibodies, in the frame of a prospective clinical trial on pregnancy vaccination in Belgium. Infants born from Tdap (Boostrix®) vaccinated (N = 55) and unvaccinated (N = 26) mothers were immunized with a hexavalent pertussis containing vaccine (Infanrix Hexa®) at 8, 12 and 16 weeks, followed by a fourth dose at 15 months of age. Right before and one month after this fourth vaccine dose, the avidity of IgG antibodies against diphtheria toxin (DT), tetanus toxin (TT), pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (Prn) was determined using 1.5 M ammonium thiocyanate as dissociating agent. In both groups, antibody avidity was moderate for TT, PT, FHA and Prn and low for DT after priming. After a fourth dose, antibody avidity increased significantly to high avidity for TT and PT, whereas it remained moderate for FHA and Prn and low for DT. The avidity correlated positively with antibody level in both study groups, yet not significantly for PT. When comparing both study groups, only PT-specific antibodies showed significantly lower avidity in infants born from vaccinated than from unvaccinated mothers after the fourth vaccine dose. The clinical significance of lower avidity of vaccine induced infant antibodies after maternal vaccination, if any, needs further investigation.

    Adjuvants in vaccines are immune stimulants that play an important role in the induction of effective and appropriate immune responses to vaccine component(s). Diphtheria-tetanus-pertussis (DPT) vaccine contains not only aluminum hydrate (alum) to enhance the immune response to the vaccine ingredients, but also, both for that purpose and as a principal ingredient, pertussis toxin (PT). However, both adjuvants strongly promote T helper (Th) 2 type immune responses. Th1 and Th2 type immune responses are counterbalanced in vivo, and a Th2-prone immune response is not effective against intracellular infections but promotes IgE production, which is related to allergic disease. In this study, we used the CpG motif contained in oligodeoxynucleotide (CpG-ODN), which has an adjuvant effect and also induces the Th1 response, as an adjuvant to this vaccine, and we investigated its adjuvanticity and its potential to modulate immune responses to DPT vaccine. Administration of DPT vaccine with CpG-ODN (DPT-alum/ODN) to mice significantly reduced the total IgE levels and increased the anti-PT specific IgG2a titer in serum, in comparison with ordinary DPT vaccine (DPT-alum). Moreover, we investigated the antibody response to orally administrated ovalbumin (OVA) after vaccine administration. In the DPT-alum/ODN-administered group, the OVA specific IgE production in serum greatly decreased in comparison with that in the DPT-alum-administered group. These data indicate that CpG-ODN was not useful only as an efficient vaccine adjuvant but also shifted the immune responses substantially toward Th1 and modulated the Th1/Th2 immune response in DPT vaccine. These data suggested new applications of CpG-ODN as adjuvants in DPT vaccine.

    : Due to their antigenic similarities, there is a potential for immunological interaction between tetanus/diphtheria-containing vaccines and carrier proteins presented on conjugate vaccines. The interaction could, unpredictably, result in either enhancement or suppression of the immune response to conjugate vaccines if they are injected soon after or concurrently with diphtheria or tetanus toxoid. We examined this interaction among adult Australian travellers before attending the Hajj pilgrimage of 2015. We randomly assigned each participant to one of three vaccination schedules. Group A received tetanus, diphtheria and acellular pertussis vaccine (Tdap) 3-4 weeks before receiving CRM197-conjugated 13-valent pneumococcal vaccine (PCV13) coadministered with TT-conjugated quadrivalent meningococcal vaccine (MCV4). Group B received all three vaccines concurrently. Group C received PCV13 and MCV4 3-4 weeks before Tdap. Blood samples collected at baseline, at each vaccination visit and 3-4 weeks after vaccination were tested for the pneumococcal opsonophagocytic assay (OPA). A total of 166 participants aged 18-64 (median 42) years were recruited, 159 completed the study. Compared with the other groups, Group A had significantly ( P  vaccination in seven serotypes of PCV13 (1, 3, 4, 5, 14, 18C and 9V). Additionally, Group A had lower frequency of serorises (≥ 4-fold rise in OPA titres) in serotype5 (79%, p = 0.01) and 18C (73.5%, p = 0.06); whereas Groups B and C had significantly lower frequencies of serorises in Serotype 4 (82%) and 6A (73.5%), respectively. No statistically significant difference was detected across the three groups in frequencies achieving OPA titre ≥ 1:8 post-vaccination. Tdap vaccination 3-4 weeks before administration of PCV13 and MCV4 significantly reduced the GMTs to seven of the 13 pneumococcal serotypes in adults.

    Soluble tetanus-antitetanus immune complexes were prepared with affinity-chromatography and gel chromatography. Serial dilutions of these immune complex preparations were tested in a solid phase C1q radioimmunoassay. Soluble immune complexes as well as aggregated human gamma globulin of identical protein concentrations were comparatively investigated. Soluble immune complexes rendered a more sensitive standardization of RIA. According to these observations a relation between μg/ml equivalents of defined tetanus-antitetanus complexes and ng second antibody obtained in C1q-RIA was calculated. Upper limit of mean values and two standard deviations of ng second antibody obtained in investigations of 55 normal sera was designated as 1 unit immune complexes and regarded as border line of negative results. Multiplication of μg/ml immune complex equivalents of 1 unit led to a scale of 1 to 15 units, showing the area of positive results. According to these values a standardization curve was constructed allowing a conversion of ng-second antibody obtained in serum investigations into immune complex units equivalent to defined standard immune complexes. With this curve investigation results of 56 RA sera and 21 SLE sera were expressed in the range of units, making a distinct gradation of positive results and a clear cut separation of positive and negative results possible. SLE sera of patients in acute stage showed highly positive results. (orig.) [de

    This study evaluated the safety, tolerability, and immunogenicity of an investigational quadrivalent meningococcal conjugate vaccine, MenACWY-CRM, when administered concomitantly with a combined tetanus, reduced diphtheria, and acellular pertussis (Tdap) vaccine, in subjects aged 11 to 25 years. Subjects received either MenACWY-CRM and Tdap, MenACWY-CRM and saline placebo, or Tdap and saline placebo. No significant increase in reactogenicity and no clinically significant vaccine-related adverse events (AEs) occurred when MenACWY-CRM and Tdap were administered concomitantly. Similar immunogenic responses to diphtheria, tetanus, and meningococcal (serogroups A, C, W-135, and Y) antigens were observed, regardless of concomitant vaccine administration. Antipertussis antibody responses were comparable between vaccine groups for filamentous hemagglutinin and were slightly lower, although not clinically significantly, for pertussis toxoid and pertactin when the two vaccines were administered concomitantly. These results indicate that the investigational MenACWY-CRM vaccine is well tolerated and immunogenic and that it can be coadministered with Tdap to adolescents and young adults.

    Advantages to combining childhood vaccines include reducing the number of visits, injections and patient discomfort, increasing compliance and optimising prevention. The World Health Organization (WHO) recommends that routine infant immunisation programmes include a vaccination against Haemophilus influenzae (H. influenzae) type B (HIB) in the combined diphtheria-tetanus-pertussis (DTP)-hepatitis B virus (HBV) vaccination. The effectiveness and safety of the combined vaccine should be carefully and systematically assessed to ensure its acceptability by the community. To compare the effectiveness of combined DTP-HBV-HIB vaccines versus combined DTP-HBV and separate HIB vaccinations. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4), which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (January 1966 to week 1, November 2011), EMBASE (January 1990 to November 2011) and www.clinicaltrials.gov (up to April 2011). Randomised controlled trials (RCTs) or quasi-RCTs comparing vaccination with any combined DTP-HBV-HIB vaccine, with or without three types of inactivated polio virus (IPV) or concomitant oral polio vaccine (OPV) in any dose, preparation or time schedule, compared with separate vaccines or placebo, administered to infants up to two years old. Two review authors independently inspected references identified by the searches and evaluated them against the inclusion criteria, extracted data and assessed the methodological quality of included trials. Data for the primary outcome (prevention of disease) were lacking. We performed a meta-analysis to pool the results of 20 studies with 5874 participants in an immunogenicity analysis and 5232 participants in the reactogenicity analysis. There were no data on clinical outcomes for the primary outcome (prevention of disease) and all studies used immunogenicity and reactogenicity (adverse events). The number of vaccine

    Measles vaccines (MV) have sex-differential effects on mortality not explained by protection against measles infection. The authors examined whether whole-cell diphtheria-tetanus-pertussis (DTP) vaccine has sex-differential and non-specific effects. Following previous reviews and a new search, the effect of DTP on mortality up to the next vaccination was assessed in all studies where DTP was given after BCG or DTP was given after MV and there was prospective follow-up after ascertainment of vaccination status. High-mortality countries in Africa and Asia. The initial observation of negative effect of DTP generated six hypotheses, which were examined in all available studies and two randomised trials reducing the time of exposure to DTP. Consistency between studies. In the first study, DTP had negative effects on survival in contrast to the beneficial effects of BCG and MV. This pattern was repeated in the six other studies available. Second, the two 'natural experiments' found significantly higher mortality for DTP-vaccinated compared with DTP-unvaccinated children. Third, the female-male mortality ratio was increased after DTP in all nine studies; in contrast, the ratio was decreased after BCG and MV in all studies. Fourth, the increased female mortality associated with high-titre measles vaccine was found only among children who had received DTP after high-titre measles vaccine. Fifth, in six randomised trials of early MV, female but not male mortality was increased if DTP was likely to be given after MV. Sixth, the mortality rate declined markedly for girls but not for boys when DTP-vaccinated children received MV. The authors reduced exposure to DTP as most recent vaccination by administering a live vaccine (MV and BCG) shortly after DTP. Both trials reduced child mortality. These observations are incompatible with DTP merely protecting against the targeted diseases. With herd immunity to whooping cough, DTP is associated with higher mortality for girls

    Vi polysaccharide typhoid vaccines cannot be used in children vaccine prepared by binding Vi to tetanus toxoids (Vi-TT) induces protective levels even in children safety following vaccination with a Vi-TT vaccine in children 6 months to 12 years of age. Overall, 1765 subjects were recruited from two registered municipal urban slums of southern Kolkata. Most of the children of the slum dwellers attended the schools in the locality which was selected with permission from the school authority. Schools were randomly divided into vaccinated (Test group) and unvaccinated group (Control group). Children and their siblings of test group received 2-doses of PedaTyph™ vaccine at 6 weeks interval. Control group received vaccines as per national guidelines. Adverse events (AEs) were examined after 30 minutes, 1 month and clinical events were observed till 12 months post-vaccination. Incidence of culture positive typhoid fever in the control group was 1.27% vis-a-vis none in vaccine group during 12 months. In subgroup evaluated for immunogenicity, an antibody titer value of 1.8 EU/ml (95% CI: 1.5 EU/ml, 2.2 EU/ml), 32 EU/ml (95% CI: 27.0 EU/ml, 39.0 EU/ml) and 14 EU/ml (95% CI: 12.0 EU/ml, 17.0 EU/ml) at baseline, 6 weeks and 12 months, respectively was observed. Sero-conversion among the sub-group was 100% after 6 weeks of post-vaccination and 83% after 12 months considering 4-fold rise from baseline. The efficacy of vaccine was 100 % (95% CI: 97.6%, 100%) in the first year of follow-up with minimal AEs post vaccination. Vi conjugate typhoid vaccine conferred 100% protection against typhoid fever in 1765 children 6 months to 12 years of age with high immunogenicity in a subgroup from the vaccine arm.

    To examine the uptake of prenatal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) immunization among pregnant women in the United States. Using MarketScan data, we conducted a historical cohort study among pregnant women with employer-based commercial insurance in the United States who delivered between January 1, 2010, and December 31, 2014. We examined temporal trends of uptake, predictors of uptake, and timing of Tdap immunization. Among 1,222,384 eligible pregnancies in 1,147,711 women, receipt of prenatal Tdap immunization increased from 0.0% of women who delivered in January 2010 to 9.8% who delivered in October 2012 (the date of the recommendation by the Advisory Committee on Immunization Practices for Tdap during every pregnancy) to 44.4% who delivered in December 2014. Among women who received Tdap during pregnancy, the majority were immunized between 27 weeks and 36 6/7 weeks of gestation per the Advisory Committee on Immunization Practices recommendation. In multivariable analyses among women who delivered between November 2012 and December 2014, rates of prenatal Tdap immunization were lower for women younger than 25 years of age (eg, 20-24 compared with 30-34 years rate ratio [RR] 0.83, 95% confidence interval [CI] 0.85-0.88), with other children (eg, three compared with zero children: RR 0.86, 95% CI 0.84-0.88), residing in the South compared with the Midwest (RR 0.81, 95% CI 0.80-0.82), or with emergency department visits in early pregnancy (RR 0.93, 95% CI 0.92-0.95). The proportion of pregnant women who received prenatal Tdap increased with increasing gestational age at birth. By the end of 2014, fewer than half of pregnant women in the United States were receiving prenatal Tdap immunization. Implementation and dissemination strategies are needed to increase Tdap coverage among pregnant women, especially those who are young, have other children, or reside in the South.

    Schistosomiasis is a disease of major public health importance in sub-Saharan Africa. Immunoregulation begins early in schistosome infection and is characterized by hyporesponsiveness to parasite and bystander antigens, suggesting that a schistosome infection at the time of immunization could negatively impact the induction of protective vaccine responses. This study examined whether having a Schistosoma mansoni infection at the time of immunization with hepatitis B and tetanus toxoid (TT) vaccines impacts an individual's ability to achieve and maintain protective antibody levels against hepatitis B surface antigen or TT. Adults were recruited from Kisumu Polytechnic College in Western Kenya. At enrollment, participants were screened for schistosomiasis and soil transmitted helminths (STHs) and assigned to groups based on helminth status. The vaccines were then administered and helminth infections treated a week after the first hepatitis B boost. Over an 8 month period, 3 blood specimens were obtained for the evaluation of humoral and cytokine responses to the vaccine antigens and for immunophenotyping. 146 individuals were available for final analysis and 26% were S. mansoni positive (Sm+). Schistosomiasis did not impede the generation of initial minimum protective antibody levels to either hepatitis B or TT vaccines. However, median hepatitis B surface antibody levels were significantly lower in the Sm+ group after the first boost and remained lower, but not significantly lower, following praziquantel (PZQ) treatment and final boost. In addition, 8 months following TT boost and 7 months following PZQ treatment, Sm+ individuals were more likely to have anti-TT antibody levels fall below levels considered optimal for long term protection. IL-5 levels in response to in vitro TT stimulation of whole blood were significantly higher in the Sm+ group at the 8 month time period as well. Individuals with schistosomiasis at the start the immunizations were capable of

    Full Text Available Appropriate antenatal care (ANC is an important preventive public health intervention to ensure women's and newborn health outcomes. The study aimed to investigate the impact of ANC, iron-folic acid (IFA supplementation and tetanus toxoid (TT vaccination during pregnancy on child mortality in Bangladesh.A cross-sectional study of three datasets from the Bangladesh Demographic and Health Surveys for the years 2004, 2007 and 2011 were pooled and used for the analyses. A total weighted sample of 16,721 maternal responses (5,364 for 2004; 4,872 for 2007 and 6,485 for 2011 was used. Multivariate logistic models that adjusted for cluster and sampling weights were used to examine the impact of ANC, IFA supplementation and TT vaccination during pregnancy on the death of a child aged 0-28 days (neonatal, 1-11 months (post-neonatal and 12-59 months (child.Multivariable analyses revealed that the odds of postnatal and under-5 mortality was lower in mothers who had ANC [Odds Ratio (OR = 0.60, 95% confidence interval (95% CI: 0.43-0.85], IFA supplementation [OR = 0.66, 95% CI: (0.45-0.98] and ≥2 TT vaccinations (OR = 0.43, 95% CI: 0.49-0.78 for post-natal mortality; and for under-5 mortality, any form of ANC (OR = 0.69, 95% CI: 0.51-0.93, IFA supplementation (OR = 0.67, 95% CI: 0.48-0.94 and ≥2 TT vaccinations (OR = 0.50, 95% CI: 0.36-0.69. When combined, TT vaccination with IFA supplementation, and TT vaccination without IFA supplementation were protective across all groups.The study found that ANC, IFA supplementation, and TT vaccination during pregnancy reduced the likelihood of child mortality in Bangladesh. The findings suggest that considerable gains in improving child survival could be achieved through ensuring universal coverage of ANC, promoting TT vaccination during pregnancy and IFA supplementation among pregnant women in Bangladesh.

    Currently available live oral rotavirus vaccines, Rotarix(®) and RotaTeq(®), are highly efficacious in developed countries. However, the immunogenicity and efficacy of such vaccines in some developing countries are low. We reported previously that bacterially-expressed rotavirus ΔVP8* subunit vaccine candidates with P[8], P[4] or P[6] specificity elicited high-titer virus neutralizing antibodies in animals immunized intramuscularly. Of note was the finding that antibodies induced with the P[8]ΔVP8* vaccine neutralized both homotypic P[8] and heterotypic P[4] rotavirus strains to high titer. To further improve its vaccine potential, a tetanus toxoid universal CD4(+) T cell epitope P2 was introduced into P[8] or P[6]ΔVP8* construct. The resulting recombinant fusion proteins expressed in Escherichia coli were of high solubility and were produced with high yield. Two doses (10 or 20 μg/dose) of the P2-P[8]ΔVP8* vaccine or P2-P[6]ΔVP8* vaccine with aluminum phosphate adjuvant elicited significantly higher geometric mean homologous neutralizing antibody titers than the vaccines without P2 in intramuscularly immunized guinea pigs. Interestingly, high levels of neutralizing antibody responses induced in guinea pigs with 3 doses of the P2-P[8]ΔVP8* vaccine persisted for at least 6 months. Furthermore, in the gnotobiotic piglet challenge study, three intramuscular doses (50 μg/dose) of the P2-P[8]ΔVP8* vaccine with aluminum phosphate adjuvant significantly delayed the onset of diarrhea and significantly reduced the duration of diarrhea and the cumulative diarrhea score after oral challenge with virulent human rotavirus Wa (G1P[8]) strain. The P2-P[8]ΔVP8* vaccine induced serum virus neutralizing antibody and VP4-specific IgG antibody production prechallenge, and primed the pigs for higher antibody and intestinal and systemic virus-specific IFN-γ producing CD4(+) T cell responses postchallenge. These two subunit vaccines could be used at a minimum singly or

    Cationization is a strategy to enhance the permeability of antibodies to physiological membranes for potential therapeutic and diagnostic applications of these proteins, with one of its crucial points being the retention of antigen binding activity. Here, we describe the cationization of horse polyclonal anti-tetanus F(ab')(2) fragments and the development and validation of an ELISA for quantitative measurements of the binding activity of the native and cationized F(ab')(2) in cell lysates and rat plasma samples, assessing the cellular uptake and plasma kinetics of these antibodies, respectively. The method used tetanus anatoxin coated on microtitre plates as capture antigen to bind sample or standard F(ab')(2), the amount of antibody binding being quantified using, first, a secondary biotinylated anti-horse antibody/streptavidin-alkaline phosphatase complex in situ and then a measurement of the substrate product. Cationization of the F(ab')(2) was performed with putrescine at pH 4.5 using soluble carbodiimide as carboxyl activator. The average substitution ratio was determined at 3 putrescine molecules per F(ab')(2) molecule. The cationized F(ab')(2) retained roughly 80% of the initial antigen binding activity and was stable over a 1 year period of storage at -20 degrees C. The ELISA validation data showed that the method was linear for both the native and cationized F(ab')(2) using Hanks' balanced saline solution with 0.2% bovine serum albumin as assay diluent for the cell lysate samples. The useful F(ab')(2) concentration range was 2.5-25 ng/ml and the limit of quantification was 2.5 ng/ml. With rat blank plasma used as assay diluent for the rat plasma samples the useful F(ab')(2) concentration range was 3.5-25 ng/ml and the limit of quantification was 3.5 ng/ml. Specific requirements for the limits of quantification were fulfilled: precision tetanus F(ab')(2) in an HL 60 cell model, and of plasma kinetics after i.v. administration to rats.

    Full Text Available Abstract Background Adverse cardiorespiratory events including apnea, bradycardia, and desaturations have been described following administration of the first diphtheria-tetanus-pertussis-inactivated polio-Haemophilus influenzae type B (DTP-IPV-Hib immunization to preterm infants. The effect of the recent substitution of acellular pertussis vaccine for whole cell pertussis vaccine on the frequency of these events requires further study. Methods Infants with gestational age of ≤ 32 weeks who received their first DTP-IPV-Hib immunization prior to discharge from two Edmonton Neonatal Intensive Care Units January 1, 1996 to November 30, 2000 were eligible for the study. Each immunized infant was matched by gestational age to one control infant. The number of episodes of apnea, bradycardia, and/or desaturations (ABD and the treatment required for these episodes in the 72 hours prior to and 72 hours post-immunization (for the immunized cohort or at the same post-natal age (for controls was recorded. Results Thirty-four infants who received DTP-IPV-Hib with whole cell pertussis vaccine, 90 infants who received DTP-IPV-Hib with acellular pertussis vaccine, and 124 control infants were entered in the study.

    Background Adverse cardiorespiratory events including apnea, bradycardia, and desaturations have been described following administration of the first diphtheria-tetanus-pertussis-inactivated polio-Haemophilus influenzae type B (DTP-IPV-Hib) immunization to preterm infants. The effect of the recent substitution of acellular pertussis vaccine for whole cell pertussis vaccine on the frequency of these events requires further study. Methods Infants with gestational age of ≤ 32 weeks who received their first DTP-IPV-Hib immunization prior to discharge from two Edmonton Neonatal Intensive Care Units January 1, 1996 to November 30, 2000 were eligible for the study. Each immunized infant was matched by gestational age to one control infant. The number of episodes of apnea, bradycardia, and/or desaturations (ABD) and the treatment required for these episodes in the 72 hours prior to and 72 hours post-immunization (for the immunized cohort) or at the same post-natal age (for controls) was recorded. Results Thirty-four infants who received DTP-IPV-Hib with whole cell pertussis vaccine, 90 infants who received DTP-IPV-Hib with acellular pertussis vaccine, and 124 control infants were entered in the study. Fifty-six immunized infants (45.1%) and 36 control infants (29.0%) had a resurgence of or increased ABD in the 72 hours post-immunization in the immunized infants and at the same post-natal age in the controls with an adjusted odds ratio for immunized infants of 2.41 (95% CI 1.29,4.51) as compared to control infants. The incidence of an increase in adverse cardiorespiratory events post-immunization was the same in infants receiving whole cell or acellular pertussis vaccine (44.1% versus 45.6%). Eighteen immunized infants (14.5%) and 51 control infants (41.1%) had a reduction in ABD in the 72 hours post- immunization or at the equivalent postnatal age in controls for an odds ratio of 0.175 (95%CI 0.08, 0.39). The need for therapy of ABD in the immunized infants was not

    Immunisation programmes have made substantial contributions to lowering the burden of disease in children, but there is a growing need to ensure that programmes are equity-oriented. We aimed to provide a detailed update about the state of between-country inequality and within-country economic-related inequality in the delivery of three doses of the combined diphtheria, tetanus toxoid, and pertussis-containing vaccine (DTP3), with a special focus on inequalities in high-priority countries. We used data from the latest available Demographic and Health Surveys and Multiple Indicator Cluster Surveys done in 51 low-income and middle-income countries. Data for DTP3 coverage were disaggregated by wealth quintile, and inequality was calculated as difference and ratio measures based on coverage in richest (quintile 5) and poorest (quintile 1) household wealth quintiles. Excess change was calculated for 21 countries with data available at two timepoints spanning a 10 year period. Further analyses were done for six high-priority countries-ie, those with low national immunisation coverage and/or high absolute numbers of unvaccinated children. Significance was determined using 95% CIs. National DTP3 immunisation coverage across the 51 study countries ranged from 32% in Central African Republic to 98% in Jordan. Within countries, the gap in DTP3 immunisation coverage suggested pro-rich inequality, with a difference of 20 percentage points or more between quintiles 1 and 5 for 20 of 51 countries. In Nigeria, Pakistan, Laos, Cameroon, and Central African Republic, the difference between quintiles 1 and 5 exceeded 40 percentage points. In 15 of 21 study countries, an increase over time in national coverage of DTP3 immunisation was realised alongside faster improvements in the poorest quintile than the richest. For example, in Burkina Faso, Cambodia, Gabon, Mali, and Nepal, the absolute increase in coverage was at least 2·0 percentage points per year, with faster improvement in the

    Since 2005, the Advisory Committee on Immunization Practices (ACIP) has recommended a tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine booster dose for all adolescents aged 11 through 18 years (preferred at 11 through 12 years) and for those adults aged 19 through 64 years who have not yet received a dose. In October 2010, despite the lack of an approved Tdap vaccine for adults aged 65 years and older, ACIP recommended that unvaccinated adults aged 65 years and older be vaccinated with Tdap if in close contact with an infant, and that other adults aged 65 years and older may receive Tdap. In July 2011, the Food and Drug Administration (FDA) approved expanding the age indication for Boostrix (GlaxoSmithKline Biologicals, Rixensart, Belgium) to aged 65 years and older. In February 2012, ACIP recommended Tdap for all adults aged 65 years and older. This recommendation supersedes previous Tdap recommendations regarding adults aged 65 years and older.

    Full Text Available This study evaluated the performance, acceptability, and appropriateness of a new, single-use, prefilled injection device called UniJect™ for an outreach immunization application.6 Between April and June 1995, UniJect devices were used by 36 traditional birth attendants to administer tetanus toxoid injections to 2 240 pregnant women during routine, antenatal home visits in the Northern, Ichilos, and Warnes Districts of Santa Cruz, Bolivia. Because tetanus toxoid is relatively heat stable, the traditional birth attendants were able to keep the tetanus toxoid-filled UniJect devices in their homes for up to one month without refrigeration. The devices were stored, transported, and disposed of in an outreach carrier designed to reduce the risks of improper handling and disposal. Data were collected from injection recipients, traditional birth attendants, and supervisors via observation, questionnaires, and post-study interviews. The performance of the UniJect device and its acceptability among all groups was very high. The traditional birth attendants used UniJect properly and safely; there were no reports or observations of device misuse, reuse, or needle-stick. Advantages cited included the fact that the device required no assembly, offered assured sterility, and reduced vaccine wastage sometimes associated with multi-dose vials. The ability to store and transport the vaccine-filled devices without ice also greatly simplified logistics.En este estudio se evaluaron el rendimiento, la aceptabilidad y la conveniencia de la inmunización antitetánica extrainstitucional con un nuevo dispositivo hipodérmico de una sola dosis, el UniJect®.

    Concomitant administration of bivalent rLP2086 (Trumenba [Pfizer, Inc] and diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine (DTaP/IPV) was immunologically noninferior to DTaP/IPV and saline and was safe and well tolerated. Bivalent rLP2086 elicited robust and broad bactericidal antibody responses to diverse Neisseria meningitidis serogroup B strains expressing antigens heterologous to vaccine antigens after 2 and 3 vaccinations. Bivalent rLP2086, a Neisseria meningitidis serogroup B (MnB) vaccine (Trumenba [Pfizer, Inc]) recently approved in the United States to prevent invasive MnB disease in individuals aged 10-25 years, contains recombinant subfamily A and B factor H binding proteins (fHBPs). This study evaluated the coadministration of Repevax (diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine [DTaP/IPV]) (Sanofi Pasteur MSD, Ltd) and bivalent rLP2086. Healthy adolescents aged ≥11 to B proteins different from the vaccine antigens. Participants were randomly assigned to receive bivalent rLP2086 + DTaP/IPV (n = 373) or saline + DTaP/IPV (n = 376). Immune responses to DTaP/IPV in participants who received bivalent rLP2086 + DTaP/IPV were noninferior to those in participants who received saline + DTaP/IPV.The proportions of bivalent rLP2086 + DTaP/IPV recipients with prespecified seroprotective hSBA titers to the 4 MnB test strains were 55.5%-97.3% after vaccination 2 and 81.5%-100% after vaccination 3. The administration of bivalent rLP2086 was well tolerated and resulted in few serious adverse events. Immune responses to DTaP/IPV administered with bivalent rLP2086 to adolescents were noninferior to DTaP/IPV administered alone. Bivalent rLP2086 was well tolerated and elicited substantial and broad bactericidal responses to diverse MnB strains in a high proportion of recipients after 2 vaccinations, and these responses were further enhanced after 3 vaccinations.ClinicalTrials.gov identifier NCT01323270

    Full Text Available Estudou-se qual a possível interferência no desenvolvimento da imunidade antitetânica ativa em cobaias e camundongos, filhos de fêmeas vacinadas contra o tétano em diferentes épocas durante o período da prenhês. Verificou-se que a vacinação das fêmeas, em gestação não interferiu, negativamente, no desenvolvimento da imunidade ativa dos animais filhos, quando submetidos à vacinação ao redor de 60 dias após o nascimento. A presença de baixos níveis de anticorpos circulantes, recebidos congenitamente, parece ter, em determinadas condições, estimulado a resposta imunitária quando, posteriormente, os animais filhos foram vacinados contra o tétano. Sugere-se que o complexo antígeno-anticorpo formado seja capaz de melhorar a resposta imunitária induzida pelo toxóide.Possibility of interference in the development of active antitetanic immunity was studied in the offspring of guinea pigs and mice whose mothers had received antitetanic vaccine during different periods of pregnancy. Vaccination of the females during pregnancy did not interfere negatively in the development of active immunity in their offspring when the latter were vaccinated about 60 days after birth. The presence of small amounts of circulating antibodies, congenitally received, seems, under certain conditions, to stimulate the immune response upon posterior vaccination against tetanus. This suggests that the acquired antigen-antibody complex heightens the immune response induced by the toxoid.

    The immunogenicity and safety of the investigational diphtheria, tetanus, acellular pertussis, hepatitis B, poliomyelitis, Haemophilus influenzae type b (Hib) and meningococcal serogroup C (MenC) heptavalent combination vaccine were compared with those of licensed control vaccines. In this open, phase II, randomized study (NCT01090453), 480 infants from Germany, France and Canada received the heptavalent vaccine (Hepta group) or hexavalent and monovalent MenC control vaccines (HexaMenC group) co-administered with a 13-valent pneumococcal conjugate vaccine at 2, 4 and 12 months of age. Immunogenicity was measured 1 month after the second primary dose, and before and 1 month after the booster dose. Safety and reactogenicity were also evaluated. Non-inferiority of immune responses to MenC and Hib induced by 2-dose primary vaccination with the heptavalent vaccine versus control vaccines was demonstrated. In exploratory analyses, postprimary and postbooster functional antibody geometric mean titers against MenC tended to be lower (1119.5 vs. 3200.5; 2653.8 vs. 6028.4) and antibody geometric mean concentrations against Hib higher (1.594 vs. 0.671 μg/mL; 17.678 vs. 13.737 μg/mL) in the Hepta versus the HexaMenC group. The heptavalent and control vaccines were immunogenic to all other antigens, although immune responses to poliovirus were lower than expected in both groups. No differences in safety and reactogenicity profiles were detected between groups. The heptavalent vaccine induced non-inferior MenC and Hib responses compared with control vaccines. Both vaccination regimens, when administered at 2, 4 and 12 months of age, had comparable safety profiles and were immunogenic to all antigens, with lower-than-expected responses to poliomyelitis.

    Studies from low-income countries have suggested that diphtheria-tetanus-pertussis (DTP) vaccine provided after Bacille Calmette-Guerin (BCG) vaccination may have a negative effect on female survival. The authors examined the effect of DTP in a cohort of low birthweight (LBW) infants. 2320 LBW newborns were visited at 2, 6 and 12 months of age to assess nutritional and vaccination status. The authors examined survival until the 6-month visit for children who were DTP vaccinated and DTP unvaccinated at the 2-month visit. Two-thirds of the children had received DTP at 2 months and 50 deaths occurred between the 2-month and 6-month visits. DTP vaccinated children had a better anthropometric status for all indices than DTP unvaccinated children. Small mid-upper arm circumference (MUAC) was the strongest predictor of mortality. The death rate ratio (DRR) for DTP vaccinated versus DTP unvaccinated children differed significantly for girls (DRR 2.45; 95% CI 0.93 to 6.45) and boys (DRR 0.53; 95% CI 0.23 to 1.20) (p=0.018, homogeneity test). Adjusting for MUAC, the overall effect for DTP vaccinated children was 2.62 (95% CI 1.34 to 5.09); DRR was 5.68 (95% CI 1.83 to 17.7) for girls and 1.29 (95% CI 0.56 to 2.97) for boys (p=0.023, homogeneity test). While anthropometric indices were a strong predictor of mortality among boys, there was little or no association for girls. Surprisingly, even though the children with the best nutritional status were vaccinated early, early DTP vaccination was associated with increased mortality for girls.

    This study (NCT00197236) evaluated the safety and immunogenicity of a hepatitis A virus (HAV) vaccine when coadministered with diphtheria-tetanus-acellular pertussis (DTaP) and Haemophilus influenzae type b (Hib) vaccines in children 15 months of age. This was an open-labeled, multicenter study with healthy subjects enrolled and randomized (1:1:1) into 3 treatment groups. A total of 394 subjects received the first study vaccinations at 15 months of age. Group HAV (N = 135) received 2 doses of HAV vaccine 6 to 9 months apart. Group HAV+DTaP+Hib (N = 127) received HAV vaccine coadministered with DTaP and Hib vaccines and the second dose of HAV vaccine, 6 to 9 months later. Group DTaP+Hib→HAV (N = 132) received the DTaP and Hib vaccines at 15 months of age, followed by HAV vaccine 30 days later and the second dose of HAV vaccine 7 to 10 months after the DTaP+Hib vaccines. Immune responses were evaluated before the first study vaccination and 30 days after each vaccine dose. Solicited, unsolicited, and serious adverse events were collected. After 2 doses of the HAV vaccine, all subjects in the 3 groups were seropositive. The geometric mean concentration of anti-HAV antibodies ranged between 1625.1 and 1904.4 mIU/mL. Coadministration of the 3 vaccines did not impact immunogenicity of the HAV, DTaP, or Hib vaccines. Vaccines were well tolerated in all groups. A 2-dose schedule of HAV vaccine was well tolerated and immunogenic when administered to children starting at 15 months of age. Immune responses to the DTaP or Hib vaccines were similar whether they were administered alone or were coadministered with the HAV vaccine.

    A novel combined Haemophilus influenzae type b-Neisseria meningitidis serogroups A and C-tetanus-toxoid conjugate vaccine (Hib-MenAC vaccine) has been developed to protect children against diseases caused by Hib, MenA, and MenC. This study investigated the safety and immunogenicity of the Hib-MenAC vaccine administered in 2-dose series to children aged 6-23 months and in a single dose to children aged 2-5 y. A randomized, positive-controlled, non-inferiority clinical trial was conducted for 1200 healthy participants in each age group. Within each age group, participants were randomly allocated to the Hib-MenAC group or the control group at a ratio of 1:1. Adverse reactions were recorded within 28 d after each dose. Blood samples were obtained to assess immunogenicity on day 0 and at 28 d after a complete vaccination course. For the investigational vaccine, the incidence of total adverse reactions in vaccinees aged 6-23 months was 46.8% and that in vaccinees aged 2-5 y was 29.8%. Most adverse reactions were mild or moderate. One non-fatal serious adverse event occurred in the Hib-MenAC group, but was unrelated to vaccination. The seroconversion rate to the 3 components reached 94.0%, and the proportion of vaccinees with rSBA titers ≥ 1:8 and PRP ≥ 0.15 g/mL reached 97.0% in both age groups. The safety and immunogenicity of the Hib-MenAC vaccine were non-inferior when compared to the licensed vaccines. It was concluded that the novel vaccine would be expected to protect children against all of the targeted diseases.

    Incidence of meningococcal diseases is high in children, and effective vaccines are needed for this age group. In this phase II, open, controlled study, 309 children aged 2–10 y from Finland were randomized (3:1) into two parallel groups to receive one dose of meningococcal ACWY-tetanus toxoid conjugate vaccine (ACWY-TT group; n = 231) or a licensed meningococcal ACWY polysaccharide vaccine (Men-PS group; n = 78). Serum bactericidal activity using rabbit complement (rSBA) was evaluated up to three years post-vaccination. Exploratory comparisons suggested that rSBA vaccine response rates and geometric mean titers (GMTs) for each serogroup at one month post-vaccination and rSBA GMTs for serogroups A, W-135 and Y up to three years post-vaccination were higher in the ACWY-TT compared with Men-PS group, but did not detect any difference between groups in terms of rSBA-MenC GMTs at three years post-vaccination; this is explained by the higher proportion of children from the Men-PS group who were excluded because they were re-vaccinated with a monovalent meningococcal serogroup C vaccine due to loss of protective antibody levels against this serogroup. Although there was a higher incidence of local reactogenicity in the ACWY-TT group, general and unsolicited symptoms reporting rates were comparable in both groups. This study showed that MenACWY-TT was immunogenic with a clinically acceptable safety profile in children aged 2–10 y. MenACWY-TT induced higher functional antibody titers for all serogroups, which persisted longer for serogroups A, W-135 and Y, than the MenACWY polysaccharide vaccine.

Information was obtained from medical records of 152 cases and 152 controls, admitted to the tetanus unit in the State University Hospital, in Recife, from 1990 to 1995. Variables were grouped in three different sets. Crude and adjusted odds ratios, p-values and 95% confidence intervals were estimated. Variables selected in the multivariate analysis in each set were controlled for the effect of those selected in the others. All factors related to the disease progression - incubation period, time elapsed between the occurrence of the first tetanus symptom and admission, and period of onset - showed a statistically significant association with death from tetanus. Similarly, signs and/or symptoms occurring on admission or in the following 24 hours (second set: reflex spasms, neck stiffness, respiratory signs/symptoms and respiratory failure requiring artificial ventilation (third set were associated with death from tetanus even when adjusted for the effect of the others.Um estudo de caso-controle foi conduzido no Estado de Pernambuco, Brasil, para identificar fatores de risco para morte por tétano.

    In this study, we compared the immunogenicities of two lots of meningococcal ACWY-tetanus toxoid conjugate vaccine (MenACWY-TT) that differed in serogroup A polysaccharide (PS) O-acetylation levels and evaluated their immunogenicities and safety in comparison to a licensed ACWY polysaccharide vaccine (Men-PS). In this phase III, partially blinded, controlled study, 1,170 healthy subjects aged 18 to 25 years were randomized (1:1:1) to receive one dose of MenACWY-TT lot A (ACWY-A) (68% O-acetylation), MenACWY-TT lot B (ACWY-B) (92% O-acetylation), or Men-PS (82% O-acetylation). Immunogenicity was evaluated in terms of serum bactericidal activity using rabbit complement (i.e., rabbit serum bactericidal activity [rSBA]). Solicited symptoms, unsolicited adverse events (AEs), and serious AEs (SAEs) were recorded. The immunogenicities, in terms of rSBA geometric mean titers, were comparable for both lots of MenACWY-TT. The vaccine response rates across the serogroups were 79.1 to 97.0% in the two ACWY groups and 73.7 to 94.1% in the Men-PS group. All subjects achieved rSBA titers of ≥1:8 for all serogroups. All subjects in the two ACWY groups and 99.5 to 100% in the Men-PS group achieved rSBA titers of ≥1:128. Pain was the most common solicited local symptom and was reported more frequently in the ACWY group (53.9 to 54.7%) than in the Men-PS group (36.8%). The most common solicited general symptoms were fatigue and headache, which were reported by 28.6 to 30.3% and 26.9 to 31.0% of subjects, respectively. Two subjects reported SAEs; one SAE was considered to be related to vaccination (blighted ovum; ACWY-B group). The level of serogroup A PS O-acetylation did not affect vaccine immunogenicity. MenACWY-TT (lot A) was not inferior to Men-PS in terms of vaccine response and was well tolerated.

    Implementation of successful prevention of mother-to-child transmission of HIV strategies has resulted in an increased population of HIV-exposed uninfected (HEU) infants. HEU infants have higher rates of morbidity and mortality than HIV-unexposed (HU) infants. Numerous factors may contribute to poor health in HEU infants including immunological alterations. The present study assessed T-cell phenotype and function in HEU infants with a focus on memory Th1 responses to vaccination. We compared cross-sectionally selected parameters at 3 and 12 months of age in HIV-exposed (n = 42) and HU (n = 28) Kenyan infants. We measured ex vivo activated and bulk memory CD4 and CD8 T-cells and regulatory T-cells by flow cytometry. In addition, we measured the magnitude, quality and memory phenotype of antigen-specific T-cell responses to Bacillus Calmette-Guerin and Tetanus Toxoid vaccine antigens, and the magnitude and quality of the T cell response following polyclonal stimulation with staphylococcal enterotoxin B. Finally, the influence of maternal disease markers on the immunological parameters measured was assessed in HEU infants. Few perturbations were detected in ex vivo T-cell subsets, though amongst HEU infants maternal HIV viral load positively correlated with CD8 T cell immune activation at 12 months. Conversely, we observed age-dependent differences in the magnitude and polyfunctionality of IL-2 and TNF-α responses to vaccine antigens particularly in Th1 cells. These changes mirrored those seen following polyclonal stimulation, where at 3 months, cytokine responses were higher in HEU infants compared to HU infants, and at 12 months, HEU infant cytokine responses were consistently lower than those seen in HU infants. Finally, reduced effector memory Th1 responses to vaccine antigens were observed in HEU infants at 3 and 12 months and higher central memory Th1 responses to M. tuberculosis antigens were observed at 3 months only.

    Full Text Available Implementation of successful prevention of mother-to-child transmission of HIV strategies has resulted in an increased population of HIV-exposed uninfected (HEU infants. HEU infants have higher rates of morbidity and mortality than HIV-unexposed (HU infants. Numerous factors may contribute to poor health in HEU infants including immunological alterations. The present study assessed T-cell phenotype and function in HEU infants with a focus on memory Th1 responses to vaccination. We compared cross-sectionally selected parameters at 3 and 12 months of age in HIV-exposed (n = 42 and HU (n = 28 Kenyan infants. We measured ex vivo activated and bulk memory CD4 and CD8 T-cells and regulatory T-cells by flow cytometry. In addition, we measured the magnitude, quality and memory phenotype of antigen-specific T-cell responses to Bacillus Calmette-Guerin and Tetanus Toxoid vaccine antigens, and the magnitude and quality of the T cell response following polyclonal stimulation with staphylococcal enterotoxin B. Finally, the influence of maternal disease markers on the immunological parameters measured was assessed in HEU infants. Few perturbations were detected in ex vivo T-cell subsets, though amongst HEU infants maternal HIV viral load positively correlated with CD8 T cell immune activation at 12 months. Conversely, we observed age-dependent differences in the magnitude and polyfunctionality of IL-2 and TNF-α responses to vaccine antigens particularly in Th1 cells. These changes mirrored those seen following polyclonal stimulation, where at 3 months, cytokine responses were higher in HEU infants compared to HU infants, and at 12 months, HEU infant cytokine responses were consistently lower than those seen in HU infants. Finally, reduced effector memory Th1 responses to vaccine antigens were observed in HEU infants at 3 and 12 months and higher central memory Th1 responses to M. tuberculosis antigens were observed at 3 months only.

    To evaluate the immunogenicity and safety of a reduced antigen diphtheria-tetanus-acellular pertussis-inactivated poliovirus (dTap-IPV B ) vaccine (Boostrix-IPV, GSK) as a pre-school booster in 3-4 year old children as compared to dTap-IPV R (Repevax, Sanofi Pasteur), when co-administered with mumps-measles-rubella vaccine (MMRV). This phase III, open label, randomised study was conducted in the UK between April 2011 and April 2012. Children due their pre-school dTap-IPV booster vaccination were randomised 2:1 to receive one of two different dTap-IPV vaccines (dTap-IPV B or dTap-IPV R ) with blood sample for immunogenicity assessment just prior and one month after vaccination. Immune responses to diphtheria, tetanus and polio antigens were compared between the study vaccines (inferential comparison). In the absence of an accepted pertussis correlate of protection, the immunogenicity of dTap-IPV B vaccine against pertussis was compared with historical pertussis efficacy data (inferential comparison). Safety and reactogenicity of both study vaccines were evaluated. 387 children were randomised and 385 vaccinated: 255 in the dTap-IPV B group and 130 in the dTap-IPV R group. Prior to vaccination, ≥76.8% of children had anti-diphtheria and ≥65.5% had anti-tetanus titres above the protection threshold; for pertussis, the pre-vaccination seropositivity rate ranged between 18.1 and 70.6%. Both vaccines were immunogenic with 99.2-100% of children achieving titres above the pre-specified seroprotection/seropositivity thresholds. One serious adverse event not considered as causally related to the study vaccination by the study investigator was reported in the dTap-IPV B group. Non-inferiority of dTap-IPV B to dTap-IPV R was demonstrated. Both vaccines had a clinically acceptable safety and reactogenicity profile when co-administered with MMRV to children 3-4 years old.

    An understanding of the antibody persistence elicited by a combined tetanus, diphtheria, 5-component acellular pertussis, and inactivated poliovirus vaccine (Tdap-IPV) after adolescent vaccination is important to optimize booster dosing intervals. Our objectives were to compare the safety and immunogenicity of Tdap-IPV coadministered with hepatitis B vaccine (HepB) and sequential administration and evaluate humoral immunity at 3, 5, and 10 years after Tdap-IPV vaccination in adolescents. This phase II randomized, controlled, and open-label study enrolled 280 11- to 14-year-old adolescents with up to 10 years postvaccination follow-up. Group 1 (n = 145) received Tdap-IPV, followed by a HepB dose 1 month later, and group 2 (n = 135) received both vaccines simultaneously. No consistent increases in solicited reactions or unsolicited adverse events occurred with coadministration. All vaccinees attained seroprotective antibody levels at ≥0.01 IU/ml for diphtheria and tetanus, at a ≥1:8 dilution for poliovirus (serotypes 1, 2, and 3), and ≥10 mIU/ml for hepatitis B at 1 month postvaccination. Clinically relevant immunologic interactions did not occur with coadministration. For pertussis, all participants achieved seropositivity levels (at or above the lower limit of quantitation), and 72.7% to 95.8% had 4-fold increases in pertussis antibodies at 1 month postvaccination. At 10 years postvaccination, the remaining participants (62.8% of the original cohort) maintained seroprotective levels of ≥0.01 IU/ml for diphtheria and tetanus, a ≥1:8 dilution for all 3 poliovirus serotypes, and 74.1% to 98.2% maintained pertussis seropositivity levels depending on the antigen tested. There were no differences between the groups. These results support the coadministration of Tdap-IPV and HepB to adolescents and suggest that vaccination with Tdap-IPV can offer protection for 10 years after an adolescent booster vaccination.

    Full Text Available Vibrio cholerae is the cause of cholera, a severe watery diarrhea. Protection against cholera is serogroup specific. Serogroup specificity is defined by the O-specific polysaccharide (OSP component of lipopolysaccharide (LPS.Here we describe a conjugate vaccine for cholera prepared via squaric acid chemistry from the OSP of V. cholerae O1 Inaba strain PIC018 and a recombinant heavy chain fragment of tetanus toxin (OSP:rTTHc. We assessed a range of vaccine doses based on the OSP content of the vaccine (10-50 μg, vaccine compositions varying by molar loading ratio of OSP to rTTHc (3:1, 5:1, 10:1, effect of an adjuvant, and route of immunization.Immunized mice developed prominent anti-OSP and anti-TT serum IgG responses, as well as vibriocidal antibody and memory B cell responses following intramuscular or intradermal vaccination. Mice did not develop anti-squarate responses. Intestinal lamina proprial IgA responses targeting OSP occurred following intradermal vaccination. In general, we found comparable immune responses in mice immunized with these variations, although memory B cell and vibriocidal responses were blunted in mice receiving the highest dose of vaccine (50 μg. We found no appreciable change in immune responses when the conjugate vaccine was administered in the presence or absence of immunoadjuvant alum. Administration of OSP:rTTHc resulted in 55% protective efficacy in a mouse survival cholera challenge model.We report development of an Inaba OSP:rTTHc conjugate vaccine that induces memory responses and protection against cholera in mice. Development of an effective cholera conjugate vaccine that induces high level and long-term immune responses against OSP would be beneficial, especially in young children who respond poorly to polysaccharide antigens.

    2001-01-01

    Full Text Available Evaluating tetanus immune status is not yet the usual clinical practice regarding patients with chronic ulcers or myasis. However, of 858 tetanus patients at Hospital Couto Maia (Salvador, Bahia, Brazil aged 1 year or above, 2 had pressure ulcers and 17 had chronic ulceration of the lower limbs where these skin lesions were the ports of entry for Clostridium tetani. In these 19 cases, the following predisposing factors were described: venous insufficiency (n=6, sickle cell anemia (n=2, Hansen's disease (n=1, malnutrition (n=1, diabetes mellitus (n=1, trauma (n=1 and unknown factors (n=7. In 6 other cases, in addition to the Hansen's disease patient, the port of entry for tetanus was the site of extraction of Tunga penetrans larvae. In these 25 cases, the majority of patients (68% were over 40 years old (17/25 and all of these patients stated that they had either not followed a tetanus toxoid vaccination regimen (19/25, or had partially completed such a regimen, or did not give precise information (6/25. Among the same series studied, over half (52% of the patients died (13/25. We conclude that tetanus prevention must be included in the treatment of chronic skin ulcer patients, vaccination coverage should be increased among older people, and strategies aimed at improving coverage for all age groups must be reviewed.

  12. Tetanus–diphtheria–acellular pertussis vaccination for adults: an update

    Science.gov (United States)

    2017-01-01

    Although tetanus and diphtheria have become rare in developed countries, pertussis is still endemic in some developed countries. These are vaccine-preventable diseases and vaccination for adults is important to prevent the outbreak of disease. Strategies for tetanus, diphtheria, and pertussis vaccines vary from country to country. Each country needs to monitor consistently epidemiology of the diseases and changes vaccination policies accordingly. Recent studies showed that tetanus–diphtheria–acellular pertussis vaccine for adults is effective and safe to prevent pertussis disease in infants. However, vaccine coverage still remains low than expected and seroprevalence of protective antibodies levels for tetanus, diphtheria, and pertussis decline with aging. The importance of tetanus–diphtheria–acellular pertussis vaccine administration should be emphasized for the protection of young adult and elderly people also, not limited to children. PMID:28168170

  13. Effect of Chronic Social Stress on Prenatal Transfer of Antitetanus Immunity in Captive Breeding Rhesus Macaques (Macaca mulatta).

    Because tetanus can cause significant morbidity and mortality in NHP, colonywide vaccination with tetanus toxoid is recommendedfor outdoor breeding colonies of rhesus macaques, with primary immunizations commonly given to infants at 6 mo of age followed by booster vaccines every 10 y. Maternal antibodies are thought to offer protective immunity to infants younger than 6 mo. However, historical colony data from the Yerkes National Primate Research Center show a higher incidence of tetanus among infants (≤ 6 mo old) born to subordinate dams. Whether this higher incidence of infantile tetanus is due to a higher incidence of trauma among subordinate animals or is a stress-induced impairment of maternal antibody protection is unknown. Studies in other NHP species suggest that chronic exposure to social stressors interferes with the receptor-mediated transplacental transfer of IgG. Therefore, the primary aim of this study was to determine whether chronic stress associated with social subordination impairs prenatal transfer of antitetanus immunity in breeding female rhesus macaques. Subjects included 26 high- and 26 low-ranking adult female rhesus macaques that were nearly 5 or 10 y after their initial immunization and their nonimmunized infants. We hypothesized that infants born to subordinate dams that were nearly 10 y after immunization would have the lowest infant-to-dam antibody ratios and thus would be at greatest risk for infection. Results revealed no significant intergroup differences in infant antitetanus IgG levels. However, infant-to-dam IgG ratios against tetanus were significantly lower among subordinate animals compared with dominant macaques, after accounting for the number of years since the dam's initial vaccination. In addition, higher maternal hair cortisol levels predicted lower infant-to-dam tetanus toxoid IgG ratios. Together, these findings suggest that chronic social stress in female rhesus macaques may hamper the prenatal transfer of

    Full Text Available A cross sectional study was conducted in eight selected villages of Meerut District [UJP.} to find out infant mortality rate alongwith other various health care delivery practices associated with this. An infant mortality rate of 106.7/1000 LB was found in the study population. Infant mortality was higher in female infants, infants of mothers not availed antenatal care, not received tetanus toxoid, delivered by untrained personnel and where cow-dung was applied to cord stump. Among the causes of infant deaths prematurity or low birth weight was the commonest cause followed by respiratory infections, diarrhoeal diseases and tetanus neonatorum

    The effects of total lymphoid irradiation (TLI) on serum levels of autoantibodies, and of antibodies to diphtheria toxoid, tetanus toxoid, and pneumococcal polysaccharide in patients with lupus nephritis were compared with those previously observed in rheumatoid arthritis (RA) patients. Baseline levels of antibodies to diphtheria toxoid and tetanus toxoid decreased significantly after TLI in patients with lupus and RA, but antibody levels to pneumococcal polysaccharide remained unchanged. After TLI, the levels of antinuclear and anti-DNA antibodies were reduced significantly in lupus, but levels of rheumatoid factor, antinuclear, and antigranulocyte antibodies all tended to increase in RA

    The impact of medical documentaries on attendance to immunization sessions is not documented in developing countries. The impact of a video and TV medical documentary on women's vaccination during a catch-up tetanus collective immunization was studied in Cambodia (2002-2004). A medical video documentary produced locally was publicly shown in 10 villages chosen at random among 63 villages to be covered by collective tetanus immunization. In each village where the video was shown, 33 women, older than age 11, were selected at random and questioned about their tetanus vaccination records, to assess if they attended the video and to evaluate their knowledge about tetanus. A second interview was conducted after the first collective vaccination to check their attendance and to record reasons for non-attendance. The same interview was conducted 10 months later, after the documentary was shown on a local TV channel and a second collective tetanus vaccination conducted. Data were collected from 323 (98%) women. Seventy-eight (24%) women saw the video documentary and only eight (2.4%) saw it on TV. Compared to farmers, shopkeepers saw significantly less the documentary (χ² of Yates: 5.77,P = 0.016; 95% CI: 0.10 Women of childbearing age with no school education were significantly more attracted by the video documentary (χ² of Yates: 5.99,P = 0.01; 95% CI: 1.10 women, although their final immunization coverage was not better. The documentary did not increase the knowledge that contamination for tetanus may come from earth and tools, but not from air and water, and that all ages are at-risk for tetanus, but it increased significantly the knowledge that vaccination can prevent the disease (χ² of Yates: 13.98;P = 0.0001; 95% CI: 1.28 Women who saw the video documentary attended the first collective session more often than those who did not (χ² of Yates: 11.00; P = 0.0006; 95% CI: 1.23 women more than 45 years of age.

    2018-06-14

    High rates of vaccination coverage are important in preventing infectious diseases. Enforcing mandatory vaccinations is one of the strategies that some Countries adopted to protect the community when vaccination coverage is not satisfactory. In Italy, in 2017 vaccination against diphtheria, tetanus, pertussis, hepatitis B, poliovirus, Haemophilus influenzae type b, measles, mumps, rubella and varicella became compulsory in childhood. In order to contrast vaccination policies, anti-vaccination campaigns contribute to the spread of fake news. Among them, there is the false information that Italy is the only one country with mandatory vaccination policy. Aim of our study is confronting vaccination policies in children under 18 months against among different European countries for the following vaccines: diphtheria, tetanus, pertussis, hepatitis B, poliovirus, Haemophilus influenzae type b, measles, mumps, rubella and varicella. Information on policies of mandatory or recommended vaccinations of the European Countries were gathered by ECDC and compared to the Italian one. European Countries recommend or contemplate compulsory vaccines. Among them, eleven Countries (35.4%) have mandatory vaccinations for at least one out of diphtheria, tetanus, pertussis, hepatitis B, poliovirus, Haemophilus influenzae type b, measles, mumps, rubella and varicella vaccine. Not only in Italy, vaccination against diphtheria, tetanus, pertussis, hepatitis B, poliovirus, Haemophilus influenzae type b, measles, mumps, rubella and varicella is mandatory in children under 18 months. Other European countries adopted compulsory policies in order to prevent the spread of infectious diseases and to protect the community.

  2. Socio-psychological factors driving adult vaccination: a qualitative study.

    Directory of Open Access Journals (Sweden)

    Ana Wheelock

    Full Text Available While immunization is one of the most effective and successful public health interventions, there are still up to 30,000 deaths in major developed economies each year due to vaccine-preventable diseases, almost all in adults. In the UK, despite comparatively high vaccination rates among ≥65 s (73% and, to a lesser extent, at-risk ≤65 s (52% in 2013/2014, over 10,000 excess deaths were reported the previous influenza season. Adult tetanus vaccines are not routinely recommended in the UK, but may be overly administered. Social influences and risk-perceptions of diseases and vaccines are known to affect vaccine uptake. We aimed to explore the socio-psychological factors that drive adult vaccination in the UK, specifically influenza and tetanus, and to evaluate whether these factors are comparable between vaccines.20 in-depth, face-to-face interviews were conducted with members of the UK public who represented a range of socio-demographic characteristics associated with vaccination uptake. We employed qualitative interviewing approaches to reach a comprehensive understanding of the factors influencing adult vaccination decisions. Thematic analysis was used to analyze the data.Participants were classified according to their vaccination status as regular, intermittent and non-vaccinators for influenza, and preventative, injury-led, mixed (both preventative and injury-led and as non-vaccinators for tetanus. We present our finding around five overarching themes: 1 perceived health and health behaviors; 2 knowledge; 3 vaccination influences; 4 disease appraisal; and 5 vaccination appraisal.The uptake of influenza and tetanus vaccines was largely driven by participants' risk perception of these diseases. The tetanus vaccine is perceived as safe and sufficiently tested, whereas the changing composition of the influenza vaccine is a cause of uncertainty and distrust. To maximize the public health impact of adult vaccines, policy should be better

  3. Immunomodulatory effects of ResistAid™: A randomized, double-blind, placebo-controlled, multidose study.

    2013-01-01

    To evaluate the ability of a proprietary arabinogalactan extract from the larch tree (ResistAid, Lonza Ltd., Basel, Switzerland) to change the immune response in healthy adults to a standardized antigenic challenge (tetanus and influenza vaccines) in a dose-dependent manner compared to placebo. This randomized, double-blind, placebo-controlled trial included 75 healthy adults (18-61 years old). Subjects were randomized to receive either 1.5 or 4.5 g/day of ResistAid or placebo for 60 days. At day 30, subjects were administered both tetanus and influenza vaccines. Serum antigenic response (tetanus immunoglobulin G [IgG], influenza A and B IgG and immunoglobulin M [IgM]) was measured at days 45 (15 days after vaccination) and 60 (30 days after vaccination) of the study and compared to baseline antibody levels. Frequency and intensity of adverse events were monitored throughout the study. As expected, all 3 groups demonstrated an expected rise in tetanus IgG levels 15 and 30 days following the vaccine. There was a strongly significant difference in the rise in IgG levels at day 60 in the 1.5 g/day group compared to placebo (p = 0.008). In the 4.5 g/day group, there was significant rise in tetanus IgG at days 45 and 60 compared to baseline (p < 0.01) but these values were not significant compared to placebo. Neither group demonstrated any significant elevations in IgM or IgG antibodies compared to placebo following the influenza vaccine. There were no clinically or statistically significant or serious adverse events. ResistAid at a dose of 1.5 g/day significantly increased the IgG antibody response to tetanus vaccine compared to placebo. In conjunction with earlier studies, this validates the effect of ResistAid on the augmentation of the response to bacterial antigens (in the form of vaccine).

    Equine serum hepatitis (i.e., Theiler's disease) is a serious and often life-threatening disease of unknown etiology that affects horses. A horse in Nebraska, USA, with serum hepatitis died 65 days after treatment with equine-origin tetanus antitoxin. We identified an unknown parvovirus in serum and liver of the dead horse and in the administered antitoxin. The equine parvovirus-hepatitis (EqPV-H) shares horses using a tetanus antitoxin contaminated with EqPV-H. Viremia developed, the horses seroconverted, and acute hepatitis developed that was confirmed by clinical, biochemical, and histopathologic testing. We also determined that EqPV-H is an endemic infection because, in a cohort of 100 clinically normal adult horses, 13 were viremic and 15 were seropositive. We identified a new virus associated with equine serum hepatitis and confirmed its pathogenicity and transmissibility through contaminated biological products.

  7. Mexico introduces pentavalent vaccine.

    Science.gov (United States)

    1999-08-01

    Combination vaccines have been introduced in Mexico. The national immunization program has incorporated the measles-mumps-rubella (MMR) vaccines in 1998, and the pentavalent vaccine in 1999. The two categories of antigen composition in combination vaccines are: 1) multiple different antigenic types of a single pathogen, such as the 23 valent pneumococcal polysaccharide vaccine, and 2) antigens from different pathogens causing different diseases, such as the DPT and MMR vaccines. Pentavalent vaccines are included in the second category. The vaccine protects against diphtheria, tetanus, pertussis, hepatitis B, and other diseases produced by Haemophilus influenzae type b (Hib). Combined diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenza type b (DTP-HB/Hib) vaccine has been distributed to 87% of Mexican children under 1 year of age. Over 800,000 doses of pentavalent vaccine have been administered.

    We examined vaccination coverage among youth with special health care needs (YSHCN) using data from parents of adolescents (11-17 years) who responded to a statewide survey in 2010-2012 (n = 2156). Using a validated screening tool, we identified 29% of adolescents as YSHCN. Weighted multivariable logistic regression assessed associations between special health care needs and receipt of tetanus booster, meningococcal, and human papillomavirus (HPV) vaccines. Only 12% of youth had received all 3 vaccines, with greater coverage for individual vaccines (tetanus booster, 91%; meningococcal, 32%; HPV, 26%). YSHCN had greater odds of HPV vaccination than other youth (33% vs 23%, OR = 1.70, 95% CI = 1.16-2.50) but vaccination coverage was similar ( P ≥ .05) for other outcomes. In subgroup analyses, HPV vaccination also differed depending on the number and type of special health care needs identified. Findings highlight low levels of vaccination overall and missed opportunities to administer recommended vaccines among all youth, including YSHCN.

    This study investigated the use of two doses of three different meningococcal group C conjugate (MCC) vaccines when given for primary immunization with a seven-valent pneumococcal conjugate vaccine (PCV7) and Pediacel, a combination product containing five acellular pertussis components, diphtheria and tetanus toxoids, Haemophilus influenzae type b (Hib) conjugate, and inactivated-poliovirus vaccine. The immune response after a single dose of MCC is also presented. Infants were randomized to receive two doses of one of the MCC vaccines and PCV7 at 2 and 3 months or at 2 and 4 months of age. Meningococcal group C serum bactericidal antibody (SBA) geometric mean titers, Hib-polyribosylribitol phosphate (PRP) immunoglobulin G (IgG) geometric mean concentrations (GMCs), and diphtheria and tetanus antitoxin GMCs, together with the proportions of infants achieving putative protective levels, were determined. A total of 393 infants were recruited. Following the first dose of NeisVac-C (MCC conjugated to tetanus toxoid), 97% of infants achieved protective levels (SBA titer of >or=8), compared with 80% and 53%, respectively, for Menjugate and Meningitec (both of which are conjugated to CRM(197)). SBA responses to MCC vaccines were not significantly different when administered at 2 and 3 or 2 and 4 months of age. Following two doses of each MCC, 98 to 100% of infants achieved protective levels. Both PRP IgG and tetanus responses were significantly enhanced when Pediacel was coadministered with NeisVac-C. This study demonstrates that NeisVac-C and Menjugate generate good immunogenicity after the first dose at 2 months of age when coadministered with PCV7 and Pediacel and merit further investigation in single-dose priming strategies.
