Neonatal Tetanus is a severe disease with high fatality. It should no longer be present in a country with the development status of Malaysia. However, sporadic cases still occur and the disease has not been eradicated. This editorial summarises the disease pattern, incidence and suggests reasons for the continued persistence of the condition locally.
Vaccines, used appropriately and efficiently, have changed the landscape of infectious diseases. Poliomyelitis is almost completely eliminated globally. In many industrialised countries, there has been over 99 percent reduction in incidence of diphtheria, tetanus, measles, mumps, rubella, Haemophilus in-fluenzae b meningitis and over 97 percent reduction in whooping cough.',2Unlike anti-biotics, most vaccines have remained equally effective despite years of continuous usage.
This paper examines the influence of maternal education on the acceptance of tetanus toxoid vaccine, using data from two villages in rural Yogyakarta, Indonesia. Maternal education results in increased tetanus toxoid uptake. Irrespective of the level of formal education, correct knowledge of the function of tetanus toxoid is positively associated with the probability of using the vaccine. It is therefore recommended that health education campaign be run to provide correct information on the importance of tetanus toxoid. This study can be used as a model for health programmes in other population with low levels of women education.

The relationship between the timing of maternal tetanus toxoid immunization and the presence of protective antitoxin in placental cord blood was investigated among women admitted to the obstetrical service of the University Hospital in Kuala Lumpur, Malaysia. The 1st dose was given between 13-39 weeks of gestation, with a median of 29 weeks. The 2nd dose was given an average of 4 weeks later. Protection was conferred on 80% or more of newborns whose mothers received their 1st tetanus toxoid injection 60 days or more before delivery. Protective levels were seen in all cord blood samples from infants whose mothers had received their 1st injection 90 days before delivery. Similarly,protective titers were found in 100% of cord blood samples when the 2nd maternal injection was give 60 days or more before delivery. There was no significant degree of protection when immunization was carried out less than 20 days before delivery. A single-dose schedule provided no protection when less than 70 days before delivery. Cord and maternal antiotoxin titers differed by no more than 1 2-fold dilution for almost all of the individual paired sera. A cord: maternal antitoxin ratio of 2 was more likely to occur with increasing time between the 2nd injection and delivery. Overall, these findings indicate that the 1st injection of a 2-dose maternal tetanus toxoid schedule should be given at least 60 days and preferably 90 days before delivery.
There is a high incidence of tetanus in the Malaysian state of Kelantan. Out of 162 reported cases of tetanus in Peninsular Malaysia during 1979 - 1984, 62 cases were from Kelantan, i.e. 38% of the total reported cases in Peninsular Malaysia. Thus a retrospective study was carried out to analyse the possible factors responsible for this high incidence. 62 cases of tetanus admitted to the General Hospital, Kota Bharu, over a period of 1979 - 1984 were studied.
Neonatal tetanus, though still existing, had been considerably reduced compared to the preceding five-year period (1975-1979). There was notable absence of cases in the two months to four-year age group, 24% of the cases occurred in the 10 - 20 years, and 29% in the age group 25 - 40 years. Since tetanus is a disease preventable by active immunization. l every effort must be taken to improve immunization coverage and increase the public awareness to prevent unnecessary loss of lives.
The aim of this study was to investigate whether Spirulina (Arthrospira) supplementation could enhance the immune response to tetanus toxoid (TT) vaccine in a mouse model. Vaccination of TT was performed on day 7 and 21 in mice fed daily with Spirulina (50 and 150 mg/kg body weight). Both Spirulina supplementation and TT vaccination did not significantly affect body weight gain of the mice. Supplementation of Spirulina significantly enhanced IgG level (p = .01) after the first but not after the second TT vaccination. The anti-TT IgG levels of the groups that received low dose and high dose of Spirulina were not significantly different. Spirulina supplementation did not show significant effects on in vitro splenocyte proliferation and cytokine (IFN-γ and IL-4) production induced by Con A and TT. This study showed that Spirulina supplementation could enhance primary immune response in terms of antibody production, but not secondary immune response following TT vaccination in a mouse model.
Vitamin E is an essential fat-soluble vitamin that has been shown to induce favorable effects on animal and human immune systems. The objective of this study was to assess the effects of tocotrienol-rich fraction (TRF) supplementation on immune response following tetanus toxoid (TT) vaccine challenge in healthy female volunteers.
To verify the actual immunisation coverage in Kuala Lumpur, City Hall Health Department and the Malaysian Paediatric Association (NGO ) carried out a survey. The survey revealed that the immunisation coverage determined at the child's first birthday for BCG was 95%, DPT 3 94%, OPV 3 94%, and measles = 27% (59% at 2 years). These figures correspond closer to City Hall's estimated coverage rather than the rates projected by the Ministry of Health. The main reasons for immunisation failure were, child ill 31.8% (not brought = 20.1%, brought but not given vaccine 11.7%), lack of information 28.6%, lack of motivation 9.1%, mother too busy 9.1%. Measles immunisation coverage at 1 year was low because of wrong information on schedules. Tetanus toxoid immunisation coverage of pregnant women was low. Only 27% of children were protected against neonatal tetanus although 97% of pregnant women received antenatal care and 50% had attended other health facilities as well during pregnancy. Private medical practitioners were responsible for more than 40% of all immunisations but were not submitting returns to the Health Department. Recommendations to improve immunisation coverage include education and motivation of the public and also doctors and health personnel on prevention of missed opportunities, contraindictions to immunisation and correct schedules.

Objective: To study the demographic, clinical features, management and outcome of neonatal tetanus treated at Tawau Hospital.
Method: A retrospective study of neonatal tetanus admitted to a district hospital in Sabah was conducted.
Results: In 2015, the hospital handled 18 cases of babies with neonatal tetanus in the Tawau Hospital. This implies an occurrence of 1.5 cases per month. All the mothers were non-citizens and did not have any proper antenatal follow up. All the tetanus babies required invasive mechanical ventilation with a median of 20 days (range, 5 to 32 days). The survival rate was 94.4%.
Conclusion: Despite the promotion of maternal and childhood vaccination along with hygienic practices of delivery, neonatal tetanus still remains a threat to babies born in Sabah.
Tetanus is a life-threatening infectious neurological condition that has become uncommon due to large-scale immunization campaigns. We describe a rare instance of generalized tetanus presenting with a headache on a tropical island in Malaysia. A 43-year-old woman presenting with headaches and generalized body weakness, which progressed into trismus and neck stiffness. Her medical history indicated a wound on the sole of her foot caused by shattered glass in an unhygienic area, but no tetanus prophylaxis had been administered. The patient was subsequently given immunoglobulin, tetanus toxoid, metronidazole, and sedatives in the recommended dosages. Her neurological condition improved remarkably, but she suffered blood pressure fluctuations due to dysautonomia. She was successfully discharged with complete recovery after 6 months of follow-up. The case demonstrates the significance of appropriate identification and care of tetanus, as well as the lethal effects of untreated wounds in vulnerable patients.
This study compared the ability of three forms of vitamin E [tocotrienol-rich fraction (TRF), alpha-tocopherol (α-T), and delta-tocotrienol (δ-T3)] to enhance immune response to tetanus toxoid (TT) immunisation in a mouse model. Twenty BALB/c mice were divided into four groups of five mice each. The mice were fed with the different forms of vitamin E (1 mg) or vehicle daily for two weeks before they were given the TT vaccine [4 Lf] intramuscularly (i.m.). Booster vaccinations were given on days 28 and 42. Serum was collected (days 0, 28, and 56) to quantify anti-TT levels. At autopsy, splenocytes harvested were cultured with TT or mitogens. The production of anti-TT antibodies was augmented (P < 0.05) in mice that were fed with δ-T3 or TRF compared to controls. The production of IFN-γ and IL-4 by splenocytes from the vitamin E treated mice was significantly (P < 0.05) higher than that from controls. The IFN-γ production was the highest in animals supplemented with δ-T3 followed by TRF and finally α-T. Production of TNF-α was suppressed in the vitamin E treated group compared to vehicle-supplemented controls. Supplementation with δ-T3 or TRF can enhance immune response to TT immunisation and production of cytokines that promote cell-mediated (TH1) immune response.
A 66-year-old man sustained an injury to his right foot while gardening. Despite receiving tetanus toxoid one hour later and adequate wound toilet, he developed severe tetanus complicated with autonomic dysfunction six days later. He died 20 days after admission. This case shows that tetanus toxoid alone may not be sufficient to prevent tetanus in wounded patients. Careful consideration must be given to the immune status of the patient and to the nature of the wound sustained. Incompletely immunised patients or patients with unknown immune status who sustain a tetanus prone wound should be protected with both tetanus toxoid and tetanus immunoglobulin.
KRAS G12A somatic point mutation in adenocarcinomas is categorized clinically as ineligibility criteria for anti-epidermal growth factor receptor (EGFR) monoclonal antibody therapies. In this study, a modified G12A-K-ras epitope (139A) with sequence-specific modifications to improve immunogenicity was developed as a potential vaccine against G12A-mutant KRAS cancers. Additionally, coupling of the 139A epitope with a tetanus toxoid (TTD) universal T-cell epitope to improve antigenicity was also reported. To facilitate convenient oral administration, Lactococcus lactis, which possesses innate immunomodulatory properties, was chosen as a live gastrointestinal delivery vehicle. Recombinant L. lactis strains secreting a G12A mutated K-ras control and 139A with and without TTD fusion were generated for comparative immunogenicity assessment. BALB/c mice were immunized orally, and high survivability of L. lactis passage through the gastrointestinal tract was observed. Elevations in B-cell count with a concomitant titre of antigen-specific IgG and interferon-γ secreting T-cells were observed in the 139A treated mice group. Interestingly, an even higher antigen-specific IgA response and interferon-γ secreting T-cell counts were observed in 139A-TTD mice group upon re-stimulation with the G12A mutated K-ras antigen. Collectively, these results indicated that an antigen-specific immune response was successfully stimulated by 139A-TTD vaccine, and a TTD fusion was successful in further enhancing the immune responses.
Little is known about the sero-prevalence of diphtheria anti-toxoid antibody levels among medical students in Malaysia. They too, just like other health care workers (HCWs) are at risk of contracting and transmitting diphtheria. Fortunately, this can be prevented by giving a specific vaccine: the diphtheria, tetanus and pertussis (DTP) vaccine. Nonetheless, data from local or regional surveys are needed before any decision is made by the respective authorities. General objective: We studied the epidemiology of diphtheria anti-toxoid antibody levels and vaccination history amongst medical students and staff in Faculty of Medicine and Health Sciences, Universiti Putra Malaysia. Specific objectives: We determined the level of diphtheria anti-toxoid antibodies amongst pre-clinical students and staff. Methodology: A total of 152 sera were collected from subjects aged 19 to 63, and diphtheria anti-toxoid levels were measured by an enzyme-linked immunosorbent assay. Results: One hundred and fifty-two (94.4%) blood samples out of 161 participants were successfully withdrawn, which comprised 105 (69.1%) and 47 (30.9%) medical students and staff, respectively. A total of 77.6% and the other 22.4% of the subjects had full and basic protection, respectively. Higher levels were predominant amongst males and they were 1.3 times more protected than females in 20-29 year-old group (85.1% vs 66.2%; odd ratios 1.25 [95% CI 1.03-1.50]; P=0.03). No significant difference in the levels of immunity among subjects for ethnicity and academic position (P>0.05). Recommendations: Level of full protection against diphtheria toxin should be clearly defined by broad population based studies using several comparable detection methods. Medical students and staff with basic protection should be closely monitored or should be given a booster dose for those who are at high risk of acquiring the disease. Thus, a standard degree of coverage should be clearly determined for health workers to prevent a potential outbreak. Conclusion: Students and staff possess immunity towards diptheria toxin however the level of full protective antibody is yet to be determined in future.
Whole-cell Pertussis (wcPertussis) vaccines combined with diphtheria and tetanus toxoids are effective in preventing clinical pertussis. The study aimed at determining the cost of managing fever and convulsions and cost of adverse events associated with wcPertussis. Parents who brought their children to health clinics and parents of children who were admitted for febrile convulsions were interviewed using structured questionnaire and the information were used to determine the cost of managing adverse events. Mean cost of managing mild fever per case was RM249, mean cost of managing high fever per case was RM1,036 and mean cost of managing convulsions was RM1,225. Total cost of managing adverse events was RM261 million for mild fever, RM66.7 million for high fever and RM1.3 million for convulsions. Costs of managing mild and high fever were less than the cost of managing convulsions. Total cost of managing mild fever was highest at RM261 million compared with RM66.7 million for high fever and RM1.3 million for convulsions. Thus, lower risk of adverse events actually contributed to higher costs of managing the adverse event.
