Health-related quality of life of female patients with congenital adrenal hyperplasia in Malaysia.

BACKGROUND: This study investigates the health-related quality of life (HRQOL) of female patients with congenital adrenal hyperplasia (CAH) in Malaysia. The objectives were to attain socio-demographic and medical data on these Malaysian females with CAH and establish their health-related quality of life (HRQOL) in comparison to age matched diabetic controls. METHODS: A cross-sectional study was conducted over 6 months in the two main tertiary centres for CAH patients in Malaysia. Participants including 59 female-raised CAH patients (mean age ± SD = 16.3 ± 4.2 years, range 10-28 years) compared to 57 age-matched female diabetic patients (mean age ± SD = 16.5 ± 3.4 years, range 10-26 years). Socio-demographic and medical profiles was obtained through semi-structured interviews. HRQOL of participants were evaluated utilising validated, Malay translated questionnaires which were age appropriate: Pediatric Quality of Life Inventory (PedsQL v4.0) scales for Child (8-12) and Adolescent (13-18) and Medical Outcome Survey 36-item Short Form version. These were then compared to the diabetic controls. RESULTS: The CAH participants consisted of children (ages 10-12 years, n = 12), adolescents (ages 13-17 years, n = 29) and adults (≥ 18 years, n = 18). The majority were Malays (64.4%) and had salt-wasting CAH (67.8%). There were no significant differences between the total mean score of the HRQOL of the combined children and adolescents CAH group (total mean score ± SD = 81.6 ± 17.9, 95% CI = 75.6-87.6) when compared to age-matched diabetic patients (total mean score ± SD = 80.8 ± 11.0, 95% CI = 77.0-84.5, P = 0.81, effect size = 0.05); no significant difference between the adult CAH and diabetic controls in the physical [median score (IQR) CAH vs diabetics; 49.3 (11.4) vs. 50.2 (6.1), P = 0.60, effect size = 0.09] and the mental composite scores [median score (IQR) CAH vs. diabetics; 47.8 (14.1) vs. 50.0 (10.8), P = 0.93, effect size = 0.01]. CONCLUSIONS: The HRQOL of the Malaysian CAH cohort were comparable to the diabetic controls.

Malaysian Females With Congenital Adrenal Hyperplasia: Surgical Outcomes and Attitudes.

Background: Girls born with congenital adrenal hyperplasia have virilized external genitalia. There is considerable debate regarding both the outcomes of feminizing genitoplasty and timing of the surgery in this population. Objective: To investigate outcomes of females 46,XX individuals with CAH in Malaysia, the surgical outcomes of feminizing genitoplasty (FG) and their attitudes toward surgery. Study Design: This is a cross-sectional study involving the two main tertiary centers in Malaysia. All 46,XX patients with CAH and raised female, who had undergone FG were identified and invited to participate. Data on socio-demographic, medical profiles, and attitudes toward surgery were collected. A standardized evaluation of the external genitalia was undertaken including the anatomic and cosmetic evaluation by independent gynecologists. Results: Of 61 individuals identified, 59 participated-consisting of children (n = 12), adolescents (n = 29) and adults (n = 18). All but one had classical CAH (98.3%) and had undergone FG (n = 55, 93.2%) with surgery mostly undertaken by pediatric surgeons trained in DSD work (n = 44, 74.6%). Complications overall were low (20.3%), with repeat surgery rate of 9.1%. External genital examination was performed in 38 participants. Overall 36.8% had absent clitoral glands and 39.5% had a persistent urogenital sinus and in 10.5%, no vaginal orifices were seen. Poor cosmetic outcomes were present in 42.1% with 55.3% recommended for further assessment under general anesthetic. Almost half participants did not venture an opinion on FG, those who did varied from having a positive attitude toward it (18 participants) to 3 opining that it should not be done, or avoided or delayed. From the participants, 35.5% preferred FG to be done early in life compared to 44.0% of the parents. Conclusions: The reoperation rates of the feminizing genitoplasty surgeries were low however due to the anatomic and cosmetic outcomes, reassessment of the external genitalia of these CAH patients may be required once they consider becoming sexually active as they may require further treatment. Many factors such as cultural sensitivities and access to medical treatment and late diagnoses have an impact on attitudes toward FG.

Genotype-phenotype correlation among Malaysian patients with osteogenesis imperfecta.

BACKGROUND: Osteogenesis imperfecta (OI) is a rare genetic bone disease characterized by bone fragility and low bone mass. OI was mainly caused by genetic mutations in collagen genes, COL1A1 and COL1A2. Nevertheless, new genes have been identified to be causally linked to OI. The clinical features between each OI groups share great similarities and it is sometimes difficult for clinicians to diagnose the disease accurately. Here, we identify the genetic mutations of OI patients from Malaysia and correlate the genetic mutations with the clinical features. METHOD: Targeted sequencing of fourteen genes panel was performed to identify the mutations in 29 OI patients with type I, III, IV and V disease. The mutations were determined using Ion Torrent Suite software version 5 and variant annotation was conducted using ANNOVAR. The identified mutations were confirmed using Sanger sequencing and in silico analysis was performed to evaluate the effects of the candidate mutations at protein level. RESULTS: Majority of patients had mutations in collagen genes, 48% (n = 14) in COL1A1 and 14% (n = 4) in COL1A2. Type I OI was caused by quantitative mutations in COL1A1 whereas most of type III and IV were due to qualitative mutations in both of the collagen genes. Those with quantitative mutations had milder clinical severity compared to qualitative mutations in terms of dentinogenesis imperfecta (DI), bone deformity and the ability to walk with aid. Furthermore, a few patients (28%, n = 8) had mutations in IFITM5, BMP1, P3H1 and SERPINF1. CONCLUSION: Majority of our OI patients have mutations in collagen genes, similar to other OI populations worldwide. Genotype-phenotype analysis revealed that qualitative mutations had more severe clinical characteristics compared to quantitative mutations. It is crucial to identify the causative mutations and the clinical severity of OI patients may be predicted based on the types of mutations.

Quality of Life in Children with Disorders of Sex Development.

BACKGROUND/AIMS: Disorders of sex development (DSD) are a heterogeneous group of rare conditions. Evidence-based treatment is challenged by a lack of clinical longitudinal outcome studies. We sought to investigate the quality of life of children with DSD other than congenital adrenal hyperplasia. METHODS: The participants (aged 6-18 years) were 23 patients raised as males and 7 patients raised as females. Control data were obtained from representatives of the patients' siblings matched for age and gender. The Pediatric Quality of Life InventoryTM Version 4.0 (PedsQL) Generic Core Scales were used as the study tool. RESULTS: In comparison with the reference data, the patient group had significantly lower overall PedsQL (p < 0.01) and school functioning (p < 0.01) scores. Also, the total PedsQL score was significantly lower in patients with DSD who were of female social sex as compared to the controls who were females. Family income, surgical procedures, degree of virilization, and mode of puberty did not influence the PedsQL scores. CONCLUSION: This study revealed a poorer quality of life for patients with DSD as compared to the age-matched control group. This highlights the need for a skilled multidisciplinary team to manage this group of patients.

Behavioural Problems in Children with 46XY Disorders of Sex Development.

The aim of this study is to determine the behavioural problems of children with 46XY disorders of sex development (DSD) with genital ambiguity and to identify the risk factors that may influence behaviour. The 27 participants (aged 6-18 years) consisted of 21 patients raised as boys and 6 patients raised as girls. Control data were obtained from a representative sibling of each patient who was matched for age and gender. The study tool used was the Child Behaviour Checklist (CBCL), which is a parent-administered questionnaire. The analysis of the behavioural scores revealed that the patient group had poorer scores in the total, externalizing, and internalizing realms. This group also had poorer scores in the anxious-depressed, social, and rule-breaking realms as compared to the control group. In addition, the XY-F group had higher scores (more pathological) than the XY-M group, although the difference in the scores was not statistically significant. A comparison of the prevalence of patients with scores in the clinical range with that of the control group was not statistically significant. These findings support the current recommendations that psychological counselling should be an integral part of the professional support offered to patients with DSD.

Behavioural outcome in children with congenital adrenal hyperplasia: experience of a single centre.

The aim of this study was to determine the behavioral outcome in children with CAH and to identify the risk factors that may influence it. Participants (aged 6-18 years) included 29 girls and 20 boys with CAH and unaffected siblings (25 girls and 17 boys). Psychological adjustment was assessed with parent reports on the Child Behavior Checklist (CBCL). Information about disease characteristics was obtained from medical records. Our study reveals that there was higher incidence of parent-reported problem of anxious/depressed and withdrawn/depressed behaviours, somatic complaints, social, thought, and attention problems, and rule-breaking, aggressive, internalizing, and externalizing behaviour among children with CAH compared to controls. The prevalence of internalizing behaviour problems was higher in CAH boys compared with that of controls. Psychosocial adjustment of girls with CAH was found to be similar to unaffected female controls and was within the normal population range. Family income may be associated with behavioral outcome. Glucocorticoid dose may reflect disease severity which may be associated with behavioral outcome. We conclude that internalizing behavioral problem was prevalent among boys with CAH reflecting maladaptive adjustment in coping with chronic illness. This highlighted the importance of psychological and social support for the patients and their families.
