Innovative immunosuppression in kidney transplantation: A challenge for unmet needs

Due to the optimal results obtained in kidney transplantation and to the lack of interest of the industries, new innovative drugs in kidney transplantation are difficult to be encountered. The best strategy to find the new drugs recently developed or under development is to search in the sections of kidney transplantation still not completely covered by the drugs on the market. These unmet needs are the prevention of delayed graft function (DGF), the protection of the graft over the long time and the desensitization of preformed anti human leukocyte antigen antibodies and the treatment of the acute antibody-mediated rejection. These needs are particularly relevant due to the expansion of some kind of kidney transplantation as transplantation from non-heart beating donor and in the case of antibody-incompatible grafts. The first are particularly exposed to DGF, the latter need a safe desensitization and a safe treatments of the antibody mediated rejections that often occur. Particular caution is needed in treating these drugs. First, they are described in very recent studies and the follow-up of their effect is of course rather short. Second, some of these drugs are still in an early phase of study, even if in well-conducted randomized controlled trials. Particular caution and a careful check need to be used in trials launched 2 or 3 years ago. Indeed, is always necessary to verify whether the study is still going on or whether and why the study itself was abandoned.     

Achieving high uptake of human papillomavirus vaccination in Malaysia through school-based vaccination programme

Background

In 2006, 4 years of planning was started by the Ministry of Health, Malaysia (MOH), to implement the HPV (human papillomavirus) vaccination programme. An inter-agency and multi-sectoral collaborations were developed for Malaysia’s HPV school-based immunisation programme. It was approved for nationwide school base implementation for 13-year-old girls or first year secondary students in 2010. This paper examines how the various strategies used in the implementation over the last 7?years (2010–2016) that unique to Malaysia were successful in achieving optimal coverage of the target population.

Methods

Free vaccination was offered to school girls in secondary school (year seven) in Malaysia, which is usually at the age of 13 in the index year. All recipients of the HPV vaccine were identified through school enrolments obtained from education departments from each district in Malaysia. A total of 242,638 girls aged between 12 to 13?years studying in year seven were approached during the launch of the program in 2010. Approximately 230,000 girls in secondary schools were offered HPV vaccine per year by 646 school health teams throughout the country from 2010 to 2016.

Results

Parental consent for their daughters to receive HPV vaccination at school was very high at 96–98% per year of the programme. Of those who provided consent, over 99% received the first dose each year and 98–99% completed the course per year. Estimated population coverage for the full vaccine course, considering also those not in school, is estimated at 83 to 91% per year. Rates of adverse events reports following HPV vaccination were low at around 2 per 100,000 and the majority was injection site reactions.

Conclusion

A multisectoral and integrated collaborative structure and process ensured that the Malaysia school-based HPV immunisation programme was successful and sustained through the programme design, planning, implementation and monitoring and evaluation. This is a critical factor contributing to the success and sustainability of the school-based HPV immunisation programme with very high coverage.

     

Clinical efficacy of distigmine bromide in the treatment of patients with underactive detrusor

Purpose: The aim of this study was to assess the clinical efficacy of distigmine bromide, an anti-cholinesterase agent, deemed to improve detrusor function thereby restoring normal voiding patterns in patients suffering from detrusor underactivity. Materials and methods: A total of 27 patients (11 men and 16 women) with poor detrusor function were included in the study. The diagnosis was established using pressure-flow studies. All patients received distigmine bromide at a dose of 5 mg three times daily for 4 weeks and re-attended for a follow-up urodynamic investigation. The results of baseline pressure-flow studies were compared to those after completion of treatment. Results: Treatment with distigmine bromide resulted in a statistically significant reduction of residual volume and percent residual volume, obviating the need for intermittent self-catheterisation in 11 patients. In addition, maximum flow rate and detrusor pressure at maximum flow increased, although not significantly. The drug was generally well tolerated by the majority of patients. Conclusion: Distigmine bromide shows clinical efficacy in patients with poor detrusor function and may therefore be used alternatively in selected cases.     

Relationship between breastfeeding and asthma prevalence in young children exposed to adverse childhood experiences

Objective: To investigate if duration of supplemental breastfeeding is associated with a lower asthma risk and whether adverse childhood experiences (ACEs) early in life influence this relationship in children ages 3 to 5 years. Methods: Data were from the 2011–2012 National Survey of Children's Health, a nationally representative cross-sectional survey. Modified Poisson regression models were used to estimate incident risk ratios (IRR) for lifetime and current asthma in young children aged 3 to 5 years (n = 15,642). We tested for effect measure modification using stratified analyses. Results: Exclusive breastfeeding for at least 6 months or supplemental breastfeeding for children ≥12 months significantly reduced the risk of lifetime asthma prevalence compared to never breastfed children (IRR 0.64; 95% CI: 0.46–0.88, p = 0.007; and IRR 0.68; 95% CI: 0.47–0.99, p = 0.044, respectively), adjusted for covariates. In stratified analyses, breastfeeding reduced the risk of lifetime asthma for children who experienced 1 ACE but not for children who experienced 2 or more ACEs. Conclusion: Exclusive breastfeeding for at least 6 months, with and without supplementation, appears to prevent asthma or delay its onset. The protective effect of breastfeeding was attenuated among children who experienced more than 2 ACEs. The known harmful effects that ACEs have on children's health may outweigh the benefits of breastfeeding in reducing the risk of a child developing asthma. Understanding how specific time periods in a child's life may be most affected by exposure to early life adversities, along with the protective effect of breastfeeding against asthma, are important areas of further study.     

Lung transplantation for cystic fibrosis patients with Burkholderia cepacia complex. Survival linked to genomovar type.

The number of cystic fibrosis (CF) patients undergoing lung transplant has risen over the past decade, because of a clear-cut survival benefit. However, patients with Burkholderia cepacia complex are often excluded from transplantation because of increased mortality. To determine the influence of B. cepacia complex genomovar type on transplant outcome, we undertook a retrospective study in 121 CF patients transplanted at UNC. Twenty-one and three patients, respectively, were infected pre- or postoperatively with B. cepacia complex. All posttransplant acquisitions were successfully treated. However, excess mortality occurred over the first 6 postoperative months in those infected preoperatively with B. cepacia complex compared with those not infected (33% versus 12%, p = 0.01). The 1-, 3-, and 5-yr survival were significantly lower in the B. cepacia complex cohort. Of the patients infected preoperatively, genomovar III patients were at the highest risk of B. cepacia complex-related mortality (5 of 12 versus 0 of 8, one isolate not typed; p = 0.035). Each of the B. cepacia complex-related deaths was caused by a unique genotype as determined by pulsed-field gel electrophoresis. All isolates were negative for the cable pilin gene. These results warrant a multicenter analysis of B. cepacia complex-infected patients with genomovar-typing to confirm that genomovar III patients are at highest risk for post-transplant complications.     

Prevalence, awareness, treatment and control of hypertension in Hellas, Greece: the Hypertension Study in General Practice in Hellas (HYPERTENSHELL) national study

BACKGROUND: The Hypertension Study in General Practice in Hellas (Hypertenshell) is a cross-sectional study (much like the National Health and Nutrition Examination Study) for assessing the prevalence, level of awareness, treatment, and control of hypertension in Greece. METHODS: The study was conducted with the collaboration of physicians in 98 Health Centers across Greece. Participants were interviewed about lifestyle, and blood pressure (BP) measurements were taken on two clinical visits for verification of diagnosis and control of hypertension. Hypertension was defined as systolic BP > or =140 mm Hg or diastolic BP > or =90 mm Hg, or current treatment with antihypertensive drugs; the same threshold was used for assessing control of hypertension. RESULTS: A total of 11,950 individuals participated and data for 11,540 were analyzed, comprising 0.1% of the Greek population. The prevalence of hypertension was 31.1% (men 33.6%, women 28.4%); among elderly individuals (>65 years) the prevalence was higher (65.4%). Of the hypertensive individuals, 39.8% did not know that had hypertension, yielding an awareness of 60.2%; in addition, 12.4% were aware but not treated (men 13.1%, women 11.8%). In all, 51.2% (1838) of hypertensive subjects were treated; 67.2% (1235) were treated but not controlled (men 66.7%, women 67.7%); and 32.8% (603) were treated and controlled (men 33.3%, women 32.3%). CONCLUSIONS: The results of the Hypertenshell Study indicate that hypertension is a common risk factor for cardiovascular disease in the Greek population. Awareness, treatment, and control of hypertension are comparable to the best rates of control of hypertension given for the problem, but there is a considerable potential for further improvement in the control of this disease.     

Takayasu arteritis in pregnancy: safe management options in antenatal care. Case report

Takayasu arteritis is a nonspecific chronic inflammatory vascular disease of unknown etiology with a higher incidence during the child-bearing years. It usually involves the branches of the aortic arch. Most of the patients enter the pregnancy being already diagnosed as having the disease and being on medication. The state of the disease in early pregnancy is a definitive factor for determining its management. Although it seems that pregnancy is a state favorable to this disease, nevertheless, complications should be anticipated, and close multidisciplinary maternal and fetal surveillance is mandatory. Early-onset hypertension is the commonest complication, and its magnitude during the late gestational period is the second definitive factor for the management of these pregnancies. A vaginal delivery should be aimed at term with continuous electronic fetal monitoring. The immediate postpartum period is usually uncomplicated despite the circulatory alterations that take place.     

Emergency obstetric hysterectomy

BACKGROUND: All cases of obstetric hysterectomies that were performed in our hospital during a seven-year study period were reviewed in order to evaluate the incidence, indications, risk factors, and complications associated with emergency obstetric hysterectomy. METHODS: Medical records of 45 patients who had undergone emergency hysterectomy were scrutinized and evaluated retrospectively. Maternal age, parity, gestational age, indication for hysterectomy, the type of operation performed, estimated blood loss, amount of blood transfused, complications, and hospitalization period were noted and evaluated. The main outcome measures were the factors associated with obstetric hysterectomy as well as the indications for the procedure. RESULTS: During the study period there were 32,338 deliveries and 9,601 of them (29.7%) were by cesarean section. In this period, 45 emergency hysterectomies were performed, with an incidence of 1 in 2,526 vaginal deliveries and 1 in 267 cesarean sections. All of them were due to massive postpartum hemorrhage. The most common underlying pathologies was placenta accreta (51.1%) and placenta previa (26.7%). There was no maternal mortality. CONCLUSIONS: Obstetric hysterectomy is a necessary life-saving procedure. Abnormal placentation is the leading cause of emergency hysterectomy when obstetric practice is characterized by a high cesarean section rate. Therefore, every attempt should be made to reduce the cesarean section rate by performing this procedure only for valid clinical indications.
