A clinical descriptive study was done to determine the sociodemographic, laboratory and clinical
characteristics of patients with congenital adrenal hyperplasia (CAH) referred to Hospital Putrajaya, a
tertiary endocrine centre in Malaysia. Electronic laboratory data of 51 CAH patients were obtained. The
demographics and clinical details of the study population were acquired from a questionnaire completed
by parents of participants. There were 25 males (49%) and 26 females (51%), of which, 58.8% were
Malays. Median age of participants was 4 years whilst median age at diagnosis of CAH was two years.
Parental consanguinity was documented in three patients (5.9%). Patients originated from Johor (19.6%),
Selangor (19.6%), Negeri Sembilan (17.6%) and Kedah (13.7%). Majority of patients were diagnosed
after one week of life (80.4%) although more females were diagnosed under the age of one week
compared to males (p=0.041). Most females presented with ambiguous genitalia (42.3%) [p=0.001]
whereas 72% of males presented with salt wasting (p=0.003). No significant associations between race
and all other variables, though interestingly three Malay patients presented with ambiguous genitalia
and hypertension. Equal gender distribution noted as expected in an autosomal recessive condition,
although not in keeping with other Asian countries. Early diagnosis in females attributed to obvious
genital ambiguity at birth. Varied clinical presentation, although in minority, necessitates genetic studies
for prompt diagnosis and treatment. Considering that majority of patients presented with salt wasting
and the age at diagnosis was delayed, the introduction of a neonatal screening programme is essential
in Malaysia.

Patients with diabetes have an earlier onset and increased severity of anaemia compared to those with
similar degree of renal impairment from other causes. Anaemia is associated with an increased risk
of vascular complications. In this study, we determined the prevalence of anaemia in T2DM patients
and its association with sociodemographic, clinical and laboratory parameters in an endocrine tertiary
hospital in Malaysia. This was a cross-sectional study using retrospective electronic data from January
2011 to December 2013 of 165 T2DM patients in Hospital Putrajaya. Data was analysed using IBM
SPSS Statistics version 21.0 for Windows. The prevalence of anaemia was 39.4% and majority had
normocytic normochromic (80%), mild (58.5%) anaemia. Majority were Malays (73.9%), aged below
60 with comparable gender percentage and long-standing, poorly-controlled DM [median fasting blood
sugar (FBS) 8mmol/L; glycated haemoglobin (HbA1c) 7.9%]. Using the KDIGO chronic kidney disease
(CKD) staging system, 86% of these patients were in stages 3-5. Anaemic patients had a significantly
higher serum urea, creatinine and a lower FBS, estimated glomerular filtration rate (eGFR) compared to
non-anaemic patients. Anaemic patients with diabetic nephropathy had a significantly lower haemoglobin
(Hb) compared to those without this complication (p=0.022). The sensitivity and specificity at a cut-off
eGFR value of 38.3 ml/min/1.73 m2 (maximum Youden index = 0.462) was 66.7% and 79.5%, respectively
to discriminate mild from moderate anaemia. This study shows that anaemia is already present in T2DM
patients in Hospital Putrajaya at initial presentation to the specialist outpatient clinic and is significantly
associated with CKD. Hence, it emphasises the obligatory need for routine and follow-up full blood
count monitoring in T2DM patients in primary care as well as tertiary settings in Malaysia to enable
early detection and aggressive correction of anaemia in preventing further complications.
