Distribusi Penderita Sindrom Down Berdasarkan Analisis Sitogenetika Di Laboratorium CEBIOR
Background : Down syndrome is a condition when a person has an extra number of chromosomes 21 in the form of either classical trisomy 21, translocation or mosaic. The age of the mother is one of the factors that increases the risk of having a baby with Down syndrome. Down syndrome is one of indications for cytogenetic analysis in which it shows the chromosome abnormalities.
Aim : To determine the distribution of chromosome abnormalities in patients with Down syndrome referred to Cebior Laboratory from 2006 until April 2015.
Methods : This study is a prospective and retrospective descriptive with cross-sectional design.
Results : Amongst 95 patients, there were 38 (40,0%) patients with karyotype 47,XX, +21; 50 (52,6%) patients with 47,XY, +21; 1 (1,1%) patients with 47,XX+21/ 46,XX; 2 (2,1%) patients with 47,XY, +21/ 46,XY; 1 (1,1%) patient with 46,XY, +21, t(8;21); 2 (2,1%) patient with 46,XX,+21,t(21;21)(q10;q10); and 1 (1,1%) patient with 46, XY, +21,t(21;21)(q10:q10). The distribution of maternal age with Down syndrome in descending order were 36-40 years old (31,6%), 31-35 years old (24,2%), 26-30 years old (22,1%), 41-45 years old (14,7%), and 20-25 years old (7,4%).
Conclusion : Most patients with Down syndrome had classical trisomy 21. The majority of babies with Down syndrome were born from mothers aged older than 35 years old. Therefore advanced maternal age have a higher risk for having a baby with Down syndrome
Polymorphisms of TLR4 Asp299Gly and TNF-α -308G/A in Leptospirosis
Background : TLR4 Asp299Gly and TNF-α -308G/A polymorphisms have been shown to be associated with increased susceptibility and severity of infection. TLR4 Asp299Gly polymorphism could affect the host's ability to respond to leptospira sp. TNF-α -308G/A polymorphism, is associated with the high producer of TNF-α.Methods : Total of 36 leptospirosis patients (IgM anti leptospira and MAT positive) and healthy individual with the equal number were included. The polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using site spesific restriction enzyme.Results : Distribution of homozygous wild-type TLR4 Asp299Gly polymorphism was higher in both of groups ( 94.5:97.2%.) and homozygous mutant allele was absent. There was not significantly difference of TLR4 Asp299Gly in leptospirosis patients and healthy group ( ρ=1.00; OR 0.5; 95%CI, 0.04-5.6) and between mild and severe leptospirosis (ρ=0.54; OR 1.54 ; 95% CI, 1.20-1.98). The presence of homozygous wild-type TNF-α -308G/A polymorphism was higher between leptospirosis patients and healthy group (100:94.5%) andhomozygous mutant allele was not found in both of the groups. No significantly different of TNF-α -308G>A polymorphism between leptospirosis patient and healthy group (ρ=0.49).Conclusions : In this study, the polymorphisms of TLR4 Asp299Gly and TNF-α -308G/A were not associated with the susceptibility and severity of leptospirosis

Quality of Life in Late-Treated Patients With Disorders of Sex Development: Insights for Patient-Centered Care
Background: Patients with a disorder of sex development (DSD) are born with atypical genitals or may develop atypical genitals and atypical body appearance, if left untreated. Health related quality of life (HRQoL) was assessed in Indonesian patients to whom diagnostic procedures and medical intervention had been delayed.Method: Comparison of 118 patients born with DSD, aged 6–41 years (60 children, 24 adolescents, and 34 adults) and 118 healthy control subjects matched for gender, age, and residential setting. HRQoL was measured using a translation of the TACQOL/TAAQOL.Results: According to parental and children's report, children with DSD reported more problems in social functioning and had less positive moods. Girls, in particular, reported problems in cognitive functioning. Adult patients reported more depressive moods, especially women, who reported more anger. No differences were found between in the adolescent groups.Conclusion: The data suggest that Indonesian children with DSD experienced more problems in social contact than non-affected Indonesian children, whereas Indonesian adults with DSD suffered from negative emotions more often than non-affected Indonesians. These findings on HRQoL are in line with findings on emotional functioning
Gender Development in Indonesian Children, Adolescents, and Adults with Disorders of Sex Development
Abstract In most Western countries, clinical management of disorders of sex development (DSD), including ambiguous gen-italia, begins at diagnosis soon after birth. For many Indonesian patients born with ambiguous genitalia, limited medical treat-ment is available. Consequently, affected individuals are raised with ambiguous genitalia and atypical secondary sex character-istics. We investigated gender identity and gender role behavior in 118 Indonesian subjects (77 males, 41 females) with different types of DSD in comparison with 118 healthy controls matched forgender,age,andresidentialsetting(rural,suburban,orurban).In Study 1, we report on methodological aspects of the investigation, including scale adaptation, pilot testing, and determining reliability and validity of measures. In Study 2, we report on gender devel-opment in 60 children (42 boys, 18 girls), 24 adolescents (15 boys, 9 girls), and 34 adults (19 men, 15 women) with DSD. The majority of participants with DSD never received any medical or surgical treatmentpriortothisstudy.Weobservedagenderchangeinallage groups, with the greatest incidence in adults. Among patients who changed, most changed from female to male, possessed a 46,XY karyotype, and had experienced significant masculinization during life. Gender identity confusion and cross-gender behavior was more frequently observed in children with DSD raised as girls compared to boys. Puberty and associated masculinization were related to gender problems in individuals with 46,XY DSD raised female. An integrated clinical and psychological follow-up on gender outcome is necessary prior to puberty and adulthood
Body Image and Sexuality in Indonesian Adults with a Disorder of Sex Development (DSD)
In Indonesia, disorders of sex development (DSDs) are not well recognized and medical care for affected individuals is scarce. Consequently, many patients live with ambiguous genitalia and appearance. We compared reported outcomes on body image, sexual functioning, and sexual orientation of 39 adults with DSDs (aged 18 to 41) and 39 healthy controls matched for gender, age, and residential setting (urban, suburban, rural). Differences in gender and treatment status (treated or untreated) were also explored. On body image, adults with DSDs reported dissat-isfaction with sex-related body parts. Compared to the matched controls, women with DSDs reported greater sexual distress, and men with DSDs reported lower erectile and ejaculation fre-quencies, and more dissatisfaction with sexual life but not with sexual desire and activities. Men with DSDs who had undergone genital surgery reported higher erectile and ejaculation frequen-cies than untreated men. More women than men in the DSDs group reported a nonexclusive heterosexual orientation. DSDs and infertility had a great impact on sexuality. Fear of ostra-cism complicated DSD acceptance. Findings were compared to those of Western studies. Based on these results, education about DSDs and their psychosexual consequences may help reduce the sexual distress and problems in adults with DSDs and improve quality of life
Application of the New Classification on Patients with a Disorder of Sex Development in Indonesia
Disorder of sex development (DSD) patients in Indonesia most often do not receive a proper diagnostic evaluation and treatment. This study intended to categorize 88 Indonesian patients in accordance with the new consensus DSD algorithm. Diagnostic evaluation including clinical, hormonal, genetic, imaging, surgical, and histological parameters was performed. Fifty-three patients were raised as males, and 34 as females. Of 22 patients with 46, XX DSD, 15 had congenital adrenal hyperplasia, while in one patient, an ovarian Leydig cell tumor was found. In all 58 46, XY DSD patients, 29 were suspected of a disorder of androgen action (12 with an androgen receptor mutation), and in 9, gonadal dysgenesis was found and, in 20, severe hypospadias e.c.i. Implementation of the current consensus statement in a resource-poor environment is very difficult. The aim of the diagnostic workup in developing countries should be to end up with an evidence-based diagnosis. This is essential to improve treatment and thereby to improve the patients' quality of life
Severe Dengue Is Associated with Consumption of von Willebrand Factor and Its Cleaving Enzyme ADAMTS-13
Severe dengue infections are characterized by thrombocytopenia, clinical bleeding and plasma leakage. Activation of the endothelium, the inner lining of blood vessels, leads to the secretion of storage granules called Weibel Palade bodies (WPBs). We demonstrated that severe dengue in Indonesian children is associated with a strong increase in plasma levels of the WPB constituents von Willebrand factor (VWF), VWF propeptide and osteoprotegerin (OPG). An increased amount of the hemostatic protein VWF was in a hyperreactive, platelet binding conformation, and this was most pronounced in the children who died. VWF levels at enrollment were lower than expected from concurrent VWF propeptide and OPG levels and VWF levels did not correlate well with markers of disease severity. Together, this suggests that VWF is being consumed during severe dengue. Circulating levels of the VWF-cleaving enzyme ADAMTS-13 were reduced. VWF is a multimeric protein and a subset of children had a decrease in large and intermediate VWF multimers at discharge. In conclusion, severe dengue is associated with exocytosis of WPBs with consumption of VWF and low ADAMTS-13 activity levels. This may contribute to the thrombocytopenia and complications of dengue
Disorders of sex development : insights from targeted gene sequencing of a large international patient cohort
Background: Disorders of sex development (DSD) are congenital conditions in which chromosomal, gonadal, or phenotypic sex is atypical. Clinical management of DSD is often difficult and currently only 13% of patients receive an accurate clinical genetic diagnosis. To address this we have developed a massively parallel sequencing targeted DSD gene panel which allows us to sequence all 64 known diagnostic DSD genes and candidate genes simultaneously.
Results: We analyzed DNA from the largest reported international cohort of patients with DSD (278 patients with 46, XY DSD and 48 with 46, XX DSD). Our targeted gene panel compares favorably with other sequencing platforms. We found a total of 28 diagnostic genes that are implicated in DSD, highlighting the genetic spectrum of this disorder. Sequencing revealed 93 previously unreported DSD gene variants. Overall, we identified a likely genetic diagnosis in 43% of patients with 46, XY DSD. In patients with 46, XY disorders of androgen synthesis and action the genetic diagnosis rate reached 60%. Surprisingly, little difference in diagnostic rate was observed between singletons and trios. In many cases our findings are informative as to the likely cause of the DSD, which will facilitate clinical management.
Conclusions: Our massively parallel sequencing targeted DSD gene panel represents an economical means of improving the genetic diagnostic capability for patients affected by DSD. Implementation of this panel in a large cohort of patients has expanded our understanding of the underlying genetic etiology of DSD. The inclusion of research candidate genes also provides an invaluable resource for future identification of novel genes
