Background: Androgenetic alopecia (AGA) is the most prevailing type of progressive hair loss. Thus far, some previous studies have investigated the correlation between AGA and metabolicsyndrome (MetS). However, due to the inconsistency of their results, our study aims at evaluating the association between AGA and MetS.Methods: Fifty two male patients with grade III-V AGA, based on Ebling’s scale, and 50 control subjects were enrolled in the present study. All participants were evaluated for the presenceof Mets based on the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III).Results: The prevalence of MetS was 51.3% in AGA group and 17.8% in control group (P=0.003). Among MetS parameters, Systolic blood pressure (P=0.003) and waist circumference (P<0.001)were statistically significant in AGA patients compared to the control group.Conclusion: Our study demonstrated that the association between AGA and MetS is of great importance. Therefore, early detec...

Background: Several previous studies have investigated the association between androgenetic alopecia (AGA) and metabolic syndrome (MS), with inconsistent results. Objectives of the study were to study the prevalence of metabolic syndrome in male patients of androgenetic alopecia and compare with control population and study the relationship of metabolic syndrome with different grades of AGA.Methods: This prospective hospital based case control study included 100 new clinically diagnosed males of androgenetic alopecia, and age and sex matched control group. Assessment for presence of various components of metabolic syndrome was done following a uniform protocol in cases and controls. AGA was classified as per Hamilton –Narwood classification, grade I to III was classified as mild –moderate and grade IV and higher as severe AGA.Results: Of the 100 male AGA patients (age range 21-50, mean 34.49), 36 had grade II AGA, 24 had grade III AGA, 20 had grade IV AGA, 15 had grade V AGA and 5 h...
Study of prevalence of metabolic syndrome in androgenetic alopecia
International Journal of Research in Dermatology, 2018
Background: Androgenetic alopecia (AGA) is commonly known as male pattern baldness has a prevalence of up to 50% in men worldwide. It occurs in most patients before the age of 40 years. It is characterized by a progressive conversion of terminal hair into miniaturized hair defined by various patterns. Various studies have shown that androgenetic alopecia have significant physical and psychological morbidity and a lowered dermatological life quality index.Methods: The study included 75 patients with clinical diagnosis of AGA and 75 age and sex matched controls. After taking complete history, general examination and thorough dermatological examination was performed in all cases to grade the severity of AGA. Fasting serum samples were taken from all cases and controls and assayed for fasting plasma glucose and lipid profile. Metabolic syndrome (MS) was diagnosed according to 2005 revised National Cholesterol Education Programme’s Adult Treatment Panel III (NCEP ATP III). Chi square tes...

Introduction: Men with premature androgenetic alopecia (AGA) are found to be susceptible to cardiovascular diseases, metabolic syndrome, diabetes mellitus and hypertension and also premature baldness can have a definite negative impact on self-image and self-esteem in these patients. Insulin resistance (IR), metabolic syndrome (MS) are known to be independent risk factors for coronary heart disease (CHD). The aim of this study was to assess the strength of association between MS and/or insulin resistance in males with early-onset Androgenetic alopecia (AGA). Methods: A total of 50 male patients with premature AGA attending the dermatology outpatient department and satisfying the inclusion and exclusion criteria were recruited in the study. Equal number of normal age and gender matched patients attending the dermatology OPD were taken as control group. A detailed history of the patients as per the prepared questionnaire was taken. Elaborate general, physical and systemic examination were carried out and recorded in standard proforma. Complete examination of scalp was done with emphasis on pattern and severity of hair loss. Hair loss was graded according to Hamilton-Norwood scale. Anthropometric and blood pressure measurement was done according to structured proforma. Fasting blood samples were collected and fasting insulin level, fasting blood sugar levels, high density lipoproteins, triglycerides were determined. Results: In this study, majority of patients with early onset AGA were in the age group of 22-24 years. Most common grade of hair loss was grade III a (32%) of Hamilton-Norwood scale of hair loss. 5 out of 50 cases (10%) and 2 out of 50 controls (4%) had shown association with insulin resistance and the difference between the groups was statistically insignificant (p= 0.23). 15 out of 50 cases (30%) and 4 out of 50 controls had shown association with metabolic syndrome and the difference between the group was statistically significant (p= 0.005). Conclusion: In our study, majority of patients with early onset AGA were in age group 22-24 years. 31% of cases had family history of AGA. Majority of the patients had stage III of Hamilton-Norwood scale of hair loss. Male patients with early onset AGA were not associated with IR. Metabolic syndrome was associated with male patients with early onset AGA.

Background: Androgenetic alopecia (AGA) is a common form of patterned hair loss characterized by transformation of terminal hair of the scalp to vellous hair mediated mainly by androgens. Premature androgenetic alopecia can be defined as androgenetic alopecia developing before 35 years of age and presenting with at least stage 2 of Norwood-Hamilton classification. Premature AGA not only adds to psychological stress but is also reported as a risk factor for cardiovascular diseases, metabolic syndrome and carcinoma prostrate. In many subsequent studies, AGA has been shown to be associated with several diseases such as insulin resistance (IR), abnormal serum lipid profiles and obesity. Methods: Various parameters of metabolic syndrome were measured in 75 male patients of AGA in the department of dermatology, Safdarjung hospital from June 2015 to April 2016. ECG and echocardiography was done in all patients to look for any evidence of premature coronary artery disease . Results: In our ...

Background Epidemiological studies have associated androgenetic alopecia (AGA) with severe young-age coronary artery disease and hypertension, and linked it to insulin resistance. We carried out a case–control study in age- and weight-matched young males to study the link between AGA and insulin resistance using the homeostasis model assessment of insulin resistance (HOMA-IR) index or metabolic syndrome clinical manifestations.Methods Eighty young males, 18–35 years old, with AGA ≥ stage III in the Hamilton–Norwood classification, and 80 weight- and age-matched controls were included. Alopecia, glucose, serum insulin, HOMA-IR index, lipid profile and androgen levels, as well as metabolic syndrome criteria, were evaluated.Results The HOMA-IR index was significantly higher in cases than controls. Nonobese cases had a higher mean diastolic blood pressure and a more frequent family history of AGA than nonobese controls. A borderline difference in the HOMA-IR index was found in obese AGA cases vs. obese controls [P = 0·055, 95% confidence interval (CI) 2·36–4·20 vs. 1·75–2·73]. Free testosterone values were significantly higher in controls than cases, regardless of body mass index (BMI). A statistically significant additive effect for obesity plus alopecia was found, with significant trends for insulin, the HOMA-IR index, lipids and free testosterone when BMI and alopecia status were used to classify the participants.Conclusions Our results support the recommendation for assessing insulin resistance and cardiovascular-related features and disorders in all young males with stage III or higher AGA, according to the Hamilton–Norwood classification.
Early Androgenetic Alopecia and Insulin Resistance-A case control study
Background: In Androgenetic alopecia AGA, androgens induce miniaturization of hair follicles in those genetically predisposed to baldness. The previously known association between Androgenetic Alopecia AGA and cardiovascular risk factors raises a question of common pathogenetic mechanism of these disorders. Aim: To study the association of Insulin resistance and metabolic syndrome in early onset AGA in young males Materials and Methods: This was a case control study with 30 participants in each group. Young males between 18 and 35 years of age were included in the study. Participants in the cases group had AGA greater than stage 3. Blood pressure, anthropometry, fasting insulin and glucose levels in blood, lipid profile, total and free testosterone and TSH were investigated for all participants. Insulin resistance was calculated using HOMA-IR and metabolic syndrome criteria devised by National Cholesterol Education Program Adult Treatment Pannel III NCEP ATP III was used. Results: Cases had a higher mean diastolic blood pressure and a more frequent family history of AGA than controls. Total and free testosterone levels were significantly more in participants with AGA than controls. There was no significant difference in Insulin resistance and Metabolic syndrome criteria between the cases and controls but the prevalence of Insulin resistance IR and metabolic syndrome MS increased with the severity of AGA. Conclusion: In conclusion, more studies are required in order to objectively clarify whether early AGA can be attributed to dyslipidaemia due to androgens, IR alone, or MS due to IR. In the present study we could not establish a clear cut role of IR or MS, though the testosterones were significantly higher in the AGA participants suggesting the role of androgens.
