Influence of ethnicity on different aspects of polycystic ovary syndrome: a systematic review.

This systematic review aimed to assess variations in the clinical presentation and treatment outcomes of patients with polycystic ovary syndrome (PCOS) belonging to different ethnicities. A search was performed for studies comparing various clinical aspects of PCOS in two or more different ethnic groups. After screening 2264 studies, 35 articles were included in the final analysis. In comparison with White women with PCOS (wPCOS), East Asian women with PCOS (eaPCOS) were less hirsute, whereas Hispanic women with PCOS (hPCOS), South Asian women with PCOS (saPCOS) and Middle Eastern women with PCOS (mePCOS) were more hirsute. saPCOS had higher androgen and lower sex hormone-binding globulin (SHBG) concentrations, mePCOS had higher DHEAS concentrations, and hPCOS and Black women with PCOS (bPCOS) had lower SHBG and DHEAS measures than wPCOS. Menstrual disturbances were more frequent in eaPCOS. Both saPCOS and eaPCOS had lower body mass index with increased central adiposity. hPCOS and bPCOS were more obese. saPCOS, mePCOS, hPCOS and bPCOS had a higher prevalence of insulin resistance than wPCOS. bPCOS had a better lipid profile but higher blood pressure and cardiovascular risk. Indigenous Australian women with PCOS were more obese and more insulin resistant with higher androgen concentrations. The clinical phenotype of PCOS therefore shows a wide variation depending on ethnicity.

Anxiety and depression in adult patients with familial Mediterranean fever: a study comparing patients living in Germany and Turkey.

AIM: To determine the prevalence of anxiety and depression among patients with familial Mediterranean fever (FMF) living in Germany or Turkey a prospective study was conducted. METHODS: Forty FMF patients living in Turkey (T), 40 FMF patients living in Germany (G) and 40 healthy controls living in Germany (C) were included. Patients and controls were of Turkish ancestry. G were compared to T and C. The Hospital Anxiety and Depression Scale (HADS) was used with a cut-off of ≥ 8 for each subdomain score (HADS-A, HADS-D). RESULTS: Baseline characteristics of G were comparable to T and C except for age (T: 30.5 years, G: 35.2 years, C: 34.6 years; T vs. G P = 0.045), duration of disease (T: 14.4 years, G: 24; P < 0.001), C-reactive protein (T: 0.78 mg/dL, G: 0.78 mg/dL, C: 0.35 mg/dL; G vs. C P = 0.03). Prevalence of anxiety was higher in G compared to C (T: 65%, G: 52.5%, C: 22.5%: G vs. C P < 0.05). No difference was found for the prevalence of depression (T: 30%, G: 35%, C: 20%). The association between FMF and anxiety in subjects living in Germany persisted after adjusting for age and gender in a regression analysis and was robust to an adjustment for coexisting depression. Anxiety and depression did not correlate with FMF disease severity assessed with the Pras score. CONCLUSION: Anxiety, but not depression is more common among FMF patients living in Germany compared to healthy controls. No significant difference could be found between FMF patients living in Germany or Turkey concerning the prevalence of anxiety or depression.
