Evaluation of hormone replacement therapy.

Hormone Replacement Therapy (HRT), once considered as the gold standard of treatment of menopausal symptoms and osteoporosis, introduced about seventy years ago still continuing with lot of controversies. Menopause, a transitional period of women's life, is not an illness when oestrogen level falls leading to its consequences. Results of earlier observational studies showed beneficial effects of HRT including cardiovascular protection. But all recent randomized controlled trials have failed to prove these positive effects, rather increases the cardiovascular risk and breast cancer. Women's Health Initiative(WHI), one of the recent randomized controlled trials was stopped prematurely in 2002 due to unfavorable risk-benefit ratio. HRT is not the only way of treating the menopausal symptoms and other consequences of estrogen deficiency. There are suitable alternatives without bearing the risk of HRT. Vasomotor symptoms with hot flushes and sweating experienced by about 75 percent of menopausal women can be treated with alternatives like phyto-estrogens, selective estrogen receptor modulators (SERMs), clonidine, selective serotonin reuptake inhibitors, acupuncture, exercise, behavioral therapy etc. HRT is no longer considered as the first line of treatment of postmenopausal osteoporosis. It can be treated with alternatives like regular weight bearing exercise, balanced calcium rich diet, maintaining weight, avoidance of bone robbers, (like excess alcohol, caffeine, smoking), use of SERMs etc. Use of HRT should be individualized and rationalized considering its risks and benefits.

Effects of prolonged use of injectable hormonal contraceptive on serum lipid profile.

The current study was carried out to determine serum levels of total cholesterol, triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) in human female volunteers taking injectable hormonal contraceptives. For this purpose, 200 (two hundred) subjects with age range of 20-35 years were selected. Out of them, 140 (one hundred and forty) were experimental subjects and 60 (sixty) were control. Women without hormonal contraceptive were selected as the subjects of control group. The experimental subjects were taking injectable hormonal contraceptive, DMPA (depo-medroxyprogesterone acetate) for 3-5 years uninterruptedly. The mean serum total cholesterol and mean serum triacylglycerol levels of the DMPA users were significantly (P<O.05 and P<0.01 respectively) elevated in comparison to that of the non-users. The mean serum HDL-cholesterol was decreased in subjects using DMPA in comparison to that of the control group. But the decrease was not significant (P>0.05). The mean serum LDL-cholesterol level of the subjects of DMPA users was significantly (P<0.05) elevated in comparison to that of the control.

Effect of prolonged use of injectable hormonal contraceptives on blood pressure and body weight.

The study was undertaken to determine the effect of prolonged use of injectable hormonal contraceptive on blood pressure and body weight in young women. Two hundred volunteers were selected for the purpose. Of them, one hundred and forty were taking injectable hormonal contraceptive, DMPA for 3 to 5 years uninterruptedly. Rest forty subjects served as control using no contraceptive steroid. Blood pressure, systolic as well as diastolic, was measured by sphygmomanometer. Body weight was measured by weighing machine. It was observed that there were insignificant (P>0.05) elevations of systolic and diastolic blood pressure from DMPA use. But body weight of the experimental subjects was significantly (P <0.05) increased in comparison to that of the control.
