Introduction: This prospective clinical trial was designed to assess the effects of a long-term therapy with spironolactone, with and without dietary-induced weight-loss, on clinical features, lipid profile, and insulin levels in women with polycystic ovary syndrome (PCOS). Materials and Methods: Twenty-five patients (range of age 16–32 year; 13 lean and 12 overweight) fulfilling formal diagnostic criteria for PCOS (oligomenorrhea and/or amenorrhea, biochemical and/or clinical evidence of hyperadrogenism) were studied at baseline and then received oral spironolactone (100 mg/die) for 12 months; association with lifestyle modifications was recommended to all overweight patients. Clinical, endocrine, and metabolic parameters (oral glucose tolerance test [OGTT], lipid profile) were measured at baseline and at the end of the antiandrogen treatment. Results: The therapy was associated with a significant average decline of triglycerides in overweight subjects and with increased high-density lipoprotein-cholesterol levels in lean patients. The insulin levels at 60 min during OGTT, homeostasis model assessment-insulin resistance and area under curve of insulin were significantly lowered in overweight women after 12 months of spironolactone and weight loss and no negative changes in insulin secretion and sensitivity were observed in PCOS women after pharmacological treatment alone. Conclusion: The efficacy of spironolactone on the androgenic clinical aspects of PCOS has been confirmed in this study. Furthermore, our data show that long-term treatment with spironolactone exerts no negative effects on lipoprotein profile and glucose metabolism; more relevant beneficial effects on glucose and lipid metabolism were observed when the antiandrogen was associated with weight loss in overweight PCOS women.

| Introduction|| |
Polycystic ovary syndrome (PCOS) is present in approximately 4%–7% of reproductive-aged women, and insulin resistance and hyperinsulinism affect a large part of them. Insulin resistance, combined with the worsening effect of obesity (which seems to affect 50%–55% of the PCOS population), places those women at increased risk for impaired glucose tolerance and most likely, diabetes mellitus., Insulin may affect the ovary in multiple ways, and there are suggestions that the net effect may be a disturbed ovulation and/or an increased androgen production in many cases., On the other hand, androgens may induce insulin resistance, through changes in muscle fiber structure. As androgen excess and hyperinsulinemia contribute to a different degree on the PCOS, therapeutic efforts have been focused on agents which could treat or modify both cluster of clinical manifestations.
Most reports suggest that the lipid profile of women with PCOS is characterized by elevated serum levels of total cholesterol (TC), low density lipoproteins (LDL), very LDL (VLDL), and triglycerides (TGC) with concomitant reduction of high-density lipoprotein (HDL) cholesterol. These abnormalities in lipid levels have serious atherogenic consequences. High LDL and low HDL, in fact, predict the development of coronary heart disease, as observed in the Framing-ham's study. It is well known that, in PCOS, obesity is associated with menstrual disorders, while weight reduction restores obesity-related menstrual disorders and infertility. Lifestyle modifications, such as food restriction and physical activity, are then likely to be the first and most recommended approach in overweight women with PCOS.
The present study was designed to assess the efficacy of a long-term oral treatment with spironolactone (used as a single agent, 100 mg/die) on clinical features, metabolic profile in lean, and obese women with PCOS. A low calorie diet associated with pharmacological treatment was recommended to all our overweight patients, but only in a subgroup of them we could observe a significant weight loss. After 12 months, overweight women could then be divided into two groups, the comparison of these being of great interest in order to define the contribution of weight loss to the decrease in insulin secretion.
| Materials and Methods|| |
Twenty five women, aged between 16 and 32 year, were recruited for the study. All these subjects were referred to our division for menstrual abnormalities, with hirsutism and/or acne and alopecia. All subjects were in good health and none of them had received any drugs known to interfere with hormonal levels in the past 3 months. Diagnosis of PCOS was based on the presence of chronic anovulation (oligomenorrhea and/or amenorrhea), one or more signs of clinical hyperandrogenism, such as acne, alopecia, seborrhea, and hirsutism with a modified Ferriman-Gallwey (FG) score >8, and/or endocrinological abnormalities (increased testosterone, DHEA-S and/or and rostenedione concentrations in the early follicular phase).
Thyroid function and Prolactin secretion were normal. Cushing's syndrome and congenital adrenal hyperplasia were excluded.
The research protocol was approved by the local ethic board. Informed written consent was obtained from all participants (and at least one parent when the subject was <18 year of age).
Protoco/Clinical features, such as body mass index (BMI), FG score, acne (classified according to Lucky's score), alopecia (classified according to Ludwig's score), blood pressure (BP), endocrine (luteinizing hormone, follicle-stimulating hormone, testosterone, DHEA-S, and rostenedione, PRL) and metabolic (TGC, TC, and HDL) parameters, were evaluated in lean and overweight patients with PCOS. An oral glucose tolerance test (OGTT) was performed in all patients, without regard to their personal or family history of glucose intolerance.
The BP was measured in the right upper arm with a standard sphygmomanometer in the sitting position. The baseline evaluations were performed as follows: Blood samples were collected at 08:00 h after an overnight fast to determine serum levels of steroids (testosterone, androstenedione, DHEA-S) and lipids (TC and HDL-cholesterol, TGC). The OGTT was performed after an overnight fast of at least 10 h. A fasting blood sample was obtained at time 0 (between 08: 00 and 10:00 h) for measurement of glucose and insulin levels; another blood sample was obtained 60 and 120 min after oral administration of 75 g glucose. Glucose tolerance was evaluated using the criteria of the World Health Organization. Homeostasis model assessment-insulin resistance (HOMAIR) was calculated according to the formula (plasma glucose [mmol/I] × insulin [pU/ml]: 22.5).
The insulin response to the OGTT was also expressed as area under the curve (AUCinsulin) estimated by the trapezoidal rule.
After 12 months of oral spironolactone (100 mg/die) and lifestyle modifications, such as food restriction (1400 kCal/die), associated with pharmacological therapy in overweight PCOS patients, the following parameters were evaluated: Menstrual record, BMI, BP, FG score, TGC, TC, HDL, OGTT, AUXinsulin, and HOMAIR.
Plasma insulin was measured by a specific immunometric assay (IMMULITE 2000 [email protected], Diagnostic Products Corporation). Serum gonadotropins and androgens were measured by immunoradiometric assay. TC, HDL, and TGC were determined by the enzyme calorimetric method (HITACHI [email protected], Roche).
Data are presented as mean + SD; comparison of means was performed using Student's t-test for paired data or analysis of variance, as appropriate.
| Results|| |
Our patients were divided into two subgroups [Table 1]: 13 lean and 12 overweight patients were studied at baseline and treated with oral spironolactone (100 mg/die) for 1 year and then restudied. Lifestyle modifications, such as food restriction (1400 kcal/die), were associated with pharmacological therapy in overweight patients, but in 5 of them, the weight was almost unchanged after 12 months (Group A). Data coming from overweight women, whose weight was significantly reduced during the 12-month therapy (Group B), are reported in [Table 2].

The treatment with spironolactone showed its clinical efficacy both in lean and in overweight women as FG scores were significantly lowered from 12.2 ± 2.5 to 6.8 ± 3.7 (P = 0.0003) and from 10.1 ± 2.93 to 5.25 ± 2.6 (P = 0.0002), respectively. Acne was observed in four lean women (31%) and in 4 overweight women (33%) at baseline; we noticed a repression of the disorder in 1 of the lean and in 3 of the overweight acne-affected women after the treatment. Alopecia, which affected 7 women (3 lean and 4 overweight) at baseline, regressed only in two participants after spironolactone. Cycle menses were irregular in all our patients at baseline; 21 reported oligomenorrhea and 4 amenorrhea. After treatment, cycle menses became regular in the lean and in 4 overweight women (1 of Group A and 3 of Group B). Three lean and 4 overweight women referred polymenorrhea during treatment.
There was a trend among overweight patients to have higher levels of TGC and TC before and after treatment; the therapy was associated with a significant average decline of TGC in overweight patients (−22%, P < 0.05) and with an increased level of HDL in lean patients (−24%, P < 0.05). We also observed increased levels of TC both in lean and in obese women and increased levels of TGC in lean women (not statistically significant) after 12 months. The insulin levels at 60 min after oral glucose challenge were significantly lowered in obese women after 12 months of food restriction and spironolactone, and no significant changes were observed in PCOS women (lean and overweight) after pharmacological treatment alone. If Group A and B are compared, the decrease of BMI, insulin levels 60 min after 75 g glucose load, HOMAIR, and AUCinsulin remains significant only in Group B.
| Discussion|| |
Antiandrogenic properties of spironolactone have been demonstrated in several experimental models, and its efficacy in treatment of acne, alopecia, seborrhea, and hirsutism is well established so that it is nowadays frequently used for this purpose.
FG score was indeed decreased in all our patients, both in lean and in the two groups of overweight women. The tolerability of spironolactone was good in our patients. It is known that spironolactone may cause polyuria and polydipsia, particularly in the 1st days of treatment, and occasionally it can produce headaches, increased appetite and body weight, breast enlargement and tenderness, and dizziness. Our patients did not notice any of these side effects over the treatment period. The only unwanted effect of the therapy was polymenorrhea, which was however not relevant enough to withdraw from the treatment. Our study focused on the evaluation of the metabolic parameters. It is undeniable that the possibility of ameliorating insulin secretion and lipid profile by the treatment of hyperandrogenism would be of great interest and of important therapeutic value. Most studies have shown that insulin resistance is poorly improved in PCOS patients receiving blockers of androgen receptors or other drugs which suppress ovarian androgen secretion. Only a minority of researchers could however demonstrate that antiandrogen treatment partially reverses the defect in insulin sensitivity.
Our data, especially those coming from the comparison between the two subgroups of overweight women, showed a significant decrease of insulin in patients who associated lifestyle modifications to pharmacological therapy. Both HOMAIR and AUCinsulin were significantly decreased after 12 months, while they were unchanged in patients treated with spironolactone alone without a decrease of BMI. It is worth noting that in patients treated with spironolactone alone (lean and overweight Group A patients) glucose metabolism, as well as lipid profile, was not impaired by long term therapy.
In women with PCOS, the comparison of different treatment regimens (including combined oral contraceptives and spironolactone) showed that HDL cholesterol levels were increased. Wild et al. reported that long-term treatment with oral contraceptives was associated with increased TGC levels, which was not observed in women treated with spironolactone.
Most of the subjects of the present trial were not affected with dyslipidemia. We could observe increased levels of HDL cholesterol after therapy, which was significant only in lean subjects. This observation, however, should be confirmed by studying a more consistent number of subjects. Furthermore, there was a significant decrease in serum TGC in overweight women after pharmacological treatment; this effect may be correlated with food restriction and decrease of BMI rather than with spironolactone treatment. Obesity, which is frequently associated with PCOS, seems to amplify the degree of insulin resistance. A number of investigators have confirmed the findings of Dunaif et al., whose studies have established that the magnitude of insulin resistance in PCOS is greater than that which can be accounted for by obesity alone. Other studies however were able to show that obese women, especially those with the abdominal obesity phenotype, are more insulin resistant than their normal-weight counterparts., In these trials, insulin sensitivity was evaluated by different methods such as euglycemic hyperinsulinemic clamp technique. Dietary-induced weight loss and the use of insulin-sensitizers, such as metformin, could be viewed in PCOS as a potential strategy for controlling the metabolic alteration and preventing increased susceptibility to developing diabetes in overweight PCOS women. Our data confirm that, in obese women with PCOS even partial weight loss may reduce glucose-stimulated insulin levels, which was not observed after pharmacological therapy alone. When it can be achieved, weight loss is probably the ideal treatment for obese women with PCOS.
| Conclusion|| |
Spironolactone showed its clinical efficacy in the treatment of hyperandrogenism associated with PCOS, and side effects were not remarkable during therapy. Furthermore, our data show that long-term treatment with spironolactone exerts no negative effects on lipoprotein profile and glucose metabolism; while beneficial effects on glucose and lipid metabolism were observed when the antiandrogen was associated with weight loss in overweight PCOS women, whose high degree of insulin resistance and impaired lipid profile are strictly connected with increased risk of cardiovascular and metabolic diseases. In any case, spironolactone seems to exert a direct effect on the increase of HDL cholesterol independently from weight loss and diet.
