Chandrika N. Wijeyaratne; Adam Balen; Julian H. Barth; Paul E. Belchetz

objective Polycystic ovary syndrome (PCOS) is more prevalent in South Asian women residing in the UK than in Caucasians. Insulin resistance (IR) is central to the pathogenesis of PCOS, while type 2 diabetes is commoner in South Asians. We aimed to determine a possible ethnic difference in the clinical and biochemical characteristics of South Asian vs. Caucasian women with PCOS.

BACKGROUND Hirsutism, defined by the presence of excessive terminal hair in androgen-sensitive areas of the female body, is one of the most common disorders in women during reproductive age. METHODS We conducted a systematic review and critical assessment of the available evidence pertaining to the epidemiology, pathophysiology, diagnosis and management of hirsutism. RESULTS The prevalence of hirsutism is ~10% in most populations, with the important exception of Far-East Asian women who present hirsutism less frequently. Although usually caused by relatively benign functional conditions, with the polycystic ovary syndrome leading the list of the most frequent etiologies, hirsutism may be the presenting symptom of a life-threatening tumor requiring immediate intervention. CONCLUSIONS Following evidence-based diagnostic and treatment strategies that address not only the amelioration of hirsutism but also the treatment of the underlying etiology is essential for the proper management of affected women, especially considering that hirsutism is, in most cases, a chronic disorder needing long-term follow-up. Accordingly, we provide evidence-based guidelines for the etiological diagnosis and for the management of this frequent medical complaint.

BACKGROUND Compared with other populations, South Asians have a greater propensity to insulin resistance and the metabolic syndrome (MetS). This is the first study to determine the distribution of phenotypes of polycystic ovary syndrome (PCOS) and their relationship to the MetS among indigenous South Asians. METHOD An evaluation of the phenotype and metabolic characteristics of PCOS was conducted by recruiting consecutive women diagnosed by Rotterdam consensus criteria from an Endocrine clinic in Colombo, Sri Lanka. Prevalence of MetS was determined, in relation to the phenotypic subgroup of PCOS and compared with ethnically matched, BMI- and age-adjusted controls (n =231). RESULTS Acanthosis nigricans (AN) occurred in 64.6% of women with PCOS (n= 469). MetS occurred in 30.6% of the PCOS group compared with 6.34% of controls (P = 0.0001). Those with PCOS and MetS had significantly higher median BMI, blood pressure (BP), fasting plasma glucose, insulin and triglycerides and lower high-density lipoprotein and sex hormone-binding globulin (SHBG), but similar testosterone concentrations compared with those with PCOS alone. Prevalence of MetS was similar in the four PCOS phenotypes, although oligomenorrhoeic women were more obese compared with the normal cycling hyperandrogenic group. Multivariate logistic regression confirmed age ≥35 years, BMI ≥25 kg/m(2) and AN as significant predictors of MetS in PCOS. Case-control comparisons showed that the presence of PCOS results in higher odds of having the MetS, a high waist circumference, elevated diastolic BP, abnormal fasting lipids and high fasting insulin and plasma testosterone concentrations. CONCLUSIONS Young indigenous South Asians with PCOS have greater odds of being centrally obese, with a third having the MetS that bears no relationship to the androgenic phenotype. Significant predictors for MetS within the PCOS cohort are advancing age, obesity determined by the Asian cut off (BMI >25 kg/m(2)) and AN, while family history of diabetes, hyperandrogenism and elevated SHBG have no predictive value.

background  Polycystic ovary syndrome (PCOS) is associated with insulin resistance and premature coronary artery disease (CAD). Hyperhomocysteinaemia is a recognized risk factor for atherosclerosis, particularly among migrant South Asians, and has recently been shown to be correlated positively with the degree of insulin resistance/hyperinsulinaemia.

Diabetes is the ninth leading cause of death in women globally. In South Asians mortality in women with diabetes stands second highest. There is a marked gender discrimination which is faced by women across South Asia esp in access to services and support for diabetes, resulting in high rates of morbidity and mortality in women with diabetes. The most important risk factor identified for the diabetes epidemic is obesity along with genetic susceptibility. Lack of health care, social and cultural disparity, discrimination at work, disparity in marriage, restricted medical facilities are prevalent. Diabetes and depression are common in women. Increasing age, low level of education, low socioeconomic conditions, difficulties posed in finding partners, frequent divorce and family history of psychiatric illness are significant risk factors for diabetes and depression. Such patients usually have poor metabolic control, higher complication rates, increased healthcare costs, lost productivity, lower quality of life as well as increased risk of death. Preconception counseling should be incorporated in the routine diabetes clinic visit for all women of childbearing potential. Women with diabetes should have information and access to contraception. Proper family planning counseling and psychological support can help stop practices such as female foeticide and multiple pregnancies. Psychological support to patients and their families are needed to break the barrier. There is emerging evidence that women with diabetes are more prone to untoward outcomes as compared to men. Central obesity, metabolic syndrome and the polycystic ovary syndrome show ethnic specific differences in South Asian women. Optimal sexuality is an integral part of holistic health. Shortage of trained female health care professionals, lack of privacy in over-crowded health care facilities, a social taboo attached to such matters, and lack of confidence in patients contribute to the neglect of sexual issues in women attending diabetes clinics across South Asia. Guidelines for counselling in female sexual dysfunction, written in culturally appropriate manner for South Asia, are needed. Diabetes affects women more severely because of their unique biological, cultural and socioeconomic circumstances. Women have limited access to health care facilities because of illiteracy, ignorance and negative social customs. Transcending the gender hierarchy and inequality is a formidable challenge. Sensitising men, empowering women on self care and providing peer support maybe the answer to this challenge. It is essential for health care providers to use appropriate coping mechanism such as building psychological contact with the patient, including family and friends as part of social support and empower patient with complete process of managing diabetes. Increasing awareness through the media, seminars, posters, group discussions and education, regular monitoring and consulting the doctor, support group for women and facilities for aerobic exercises are recommended. The health care systems should consider custom-designed prevention and control programs tailored for women based on local and regional attitudes on health care, cultural beliefs, and available social support systems. Policies that empower adolescent girls and young women to take control of their metabolic management must be encouraged. Provision of gender specific diabetes education with a holistic life-cycle approach is recommended.

Ethnic-specific polycystic ovary syndrome: epidemiology, significance and implications

Chandrika N. Wijeyaratne; Sa Dilini Udayangani; Adam Balen

Being the most common endocrinopathy of young women, polycystic ovary syndrome has much variation in its clinical expression based on ancestry. Ethnic differences of the phenotype are closely linked to its complex pathophysiology. This paper reviews data of the past three decades ensuring a precise diagnosis and taking into account underlying factors, effects of migration including heterogeneity, and diversity within each identified ethnic group. Differing expressions of hyperandrogenism, obesity, insulin resistance and metabolic manifestations of polycystic ovary syndrome occur among women from distinct geographic locations and ancestry. These ethnic phenotypes correlate with their inherent metabolic risks, skin sensitivity to androgens and social outlook that particularly affects their quality of life and health-seeking behavior. It is recommended that such ethnic variations are recognized in routine clinical practice and longitudinal data be maintained to study the true impact of such differences on disease outcomes.

Aims: The prevalence of islet cell, thyroid, adrenal and celiac disease related autoantibodies in patients with Type 1 diabetes mellitus (Type 1 DM) from Sri Lanka is described. Design and Methods: Autoantibodies to glutamic acid decarboxylase 65 (GAD65Ab), protein tyrosine phosphatase IA-2 (IA-2Ab), insulin (IAAb), thyroglobulin (TgAb), thyroid peroxidase (TPOAb), TSH receptor (TRAb), 21-hydroxylase (21-OHAb) and tissue transglutaminase (tTGAb) were measured in 122 Type 1 DM patients who had low C-peptide activity or were >20 yr old at the time of diagnosis and in 100 non-diabetic blood donors. Results: GAD65Ab and/or IA-2Ab were present in 74/122 (60.7%) Type 1 DM subjects with a significantly higher prevalence compared to non-diabetic controls (no. 100) (GAD65Ab-59 vs 4%; IA-2Ab-14 vs 0%; respectively) (p<0.001). The median (inter-quartile range) Type 1 DM duration in antibody positive subjects was 3.3 (0.99-6.9) vs 4.9 (1.7–7.5) yr in antibody negative subjects (p=0.23). IA-2Ab prevalence decreased with disease duration ≥5 yr (19 vs 4%) (p<0.001). There was no difference in the prevalence of TgAb (25 vs 33%)(p=0.21) and TPOAb (22 vs 18%) (p=0.48) in Type 1 DM and non-diabetic subjects. Also, there was no difference in TgAb and TPOAb prevalence in antibody positive Type 1 DM (34.7%) compared to antibody negative Type 1 DM (24.4%) subjects (p=0.24). tTGAb (3/119) and TRAb (1/119) were found in low prevalence and 21-OHAb were not detected. Conclusions: Diabetes associated autoantibodies were detected in the majority of Type 1 DM subjects, suggesting a major role for autoimmunity in the pathogenesis of Type 1 DM in Sri Lankans. The prevalence of TgAb and TPOAb in Type 1 DM subjects and non-diabetic controls was relatively high and similar in both groups.

Background Ischaemic heart disease is the leading cause of in-hospital mortality in Sri Lanka. Acute Coronary Syndrome Sri Lanka Audit Project (ACSSLAP) is the first national clinical-audit project that evaluated patient characteristics, clinical outcomes and care provided by state-sector hospitals. Methods ACSSLAP prospectively evaluated acute care, in-hospital care and discharge plans provided by all state-sector hospitals managing patients with ACS. Data were collected from 30 consecutive patients from each hospital during 2–4 weeks window. Local and international recommendations were used as audit standards. Results Data from 87/98 (88.7%) hospitals recruited 2177 patients, with 2116 confirmed as having ACS. Mean age was 61.4±11.8 years (range 20–95) and 58.7% (n=1242) were males. There were 813 (38.4%) patients with unstable angina, 695 (32.8%) with non-ST-elevation myocardial infarction (NSTEMI) and 608 (28.7%) with ST-elevation myocardial infarction (STEMI). Both STEMI (69.9%) and NSTEMI (61.4%) were more in males (P<0.001). Aspirin, clopidogrel and statins were given to over 90% in acute setting and on discharge. In STEMI, 407 (66.9%) were reperfused; 384 (63.2%) were given fibrinolytics and only 23 (3.8%) underwent primary percutaneous coronary intervention (PCI). Only 42.3 % had thrombolysis in <30 min and 62.5% had PCI in <90 min. On discharge, beta-blockers and ACE inhibitors/angiotensin II receptor blockers were given to only 50.7% and 69.2%, respectively and only 17.6% had coronary interventions planned. Conclusions In patients with ACS, aspirin, clopidogrel and statin use met audit standards in acute setting and on discharge. Vast majority of patients with STEMI underwent fibrinolyisis than PCI, due to limited resources. Primary PCI, planned coronary interventions and timely thrombolysis need improvement in Sri Lanka.
