Ambulatory blood pressure monitoring and active renin in menopausal women treated with amlodipine and hormone replacement therapy.

The aim of this study was to follow up the effect of an 8-week treatment with amlodipine given alone or in combination with hormone replacement therapy (HRT) on blood pressure and active renin in postmenopausal women with mild to moderate arterial hypertension using both conventional clinical blood pressure measurements and ambulatory blood pressure monitoring. Twenty-nine hypertensive menopausal women were divided randomly into two groups according to the treatment regimens: amlodipine and amlodipine plus HRT. The combination with HRT led to normalization of 24-h and daytime systolic and diastolic blood pressure. In contrast to the group treated with amlodipine alone, where a significant fall only of systolic night-time blood pressure was observed, in the group treated with amlodipine plus HRT both systolic and diastolic night-time blood pressure decreased significantly. Active renin did not change significantly after treatment in both groups. Triglycerides decreased significantly and high-density lipoprotein-cholesterol increased significantly only after amlodipine treatment. There were no significant differences in serum total cholesterol and low-density lipoprotein-cholesterol after HRT plus amlodipine. In conclusion, amlodipine is effective in reducing blood pressure in postmenopausal women. The maintenance of a normal circadian blood pressure pattern was influenced by HRT.

Effect of amlodipine and hormone replacement therapy on blood pressure and bone markers in menopause.

The aim of this study was to observe the effect of an 8-week treatment with amlodipine, alone or in combination with hormone replacement therapy (HRT), on blood pressure (BP), serum osteocalcin, bone-specific alkaline phosphatase (B-ALP) and urine deoxypiridinoline in postmenopausal osteoporotic women with mild-to-moderate arterial hypertension. Both conventional clinical BP measurements and ambulatory blood pressure monitoring (ABPM) were used. Twenty hypertensive menopausal women with osteoporosis were randomly divided in two groups according to the treatment regimens: amlodipine and amlodipine + HRT. Neither treatment regimen significantly changed bone formation or bone resorption markers. There were no significant differences in levels of serum and urinary calcium and phosphorous or serum cholesterol and low-density lipoprotein (LDL)-cholesterol after treatment with amlodipine alone or in combination with HRT. Triglycerides were significantly decreased and high-density lipoprotein (HDL)-cholesterol was significantly increased after amlodipine treatment. Both treatment regimens significantly decreased conventionally measured BP to a similar extent. Amlodipine given alone lowered the midline estimating statistic of rhythm (MESOR; mean 24-level) of systolic BP and induced phase advances of the circadian rhythms of systolic, diastolic and mean BP. When combined with HRT, amlodipine lowered the MESOR and reduced the amplitude of systolic BP without any phase change. In conclusion, amlodipine is effective in reducing BP in postmenopausal women. The maintenance of a normal circadian BP pattern is also influenced by supplementation with 17beta-estradiol. The 8-week treatment with amlodipine alone and in combination with HRT is not associated with a marked influence on bone metabolism.

Porphyria cutanea tarda and peptic ulcer.

A high incidence of peptic ulcer was found in a retrospective study of 199 Bulgarians with porphyria cutanea tarda. Ulcers were found in 35 patients (17.59%), while its incidence in Bulgaria varies between 2.52 and 3.7%. The site of the ulcer was duodenal in 29 porphyriacs, gastric in three, both duodenal and gastric in two and pyloric in one. The pattern of localization was similar to that seen in the general population. Peptic ulcers became symptomatic before the appearance of porphyria in 30 cases. Six (17.1%) of the patients had perforations, while the frequency of this complication in the general population was 1.7-8.5%. Two porphyriacs with perforations died of peritonitis. Ulcers were found in 21 (24.4%) of 86 patients with normal activity of erythrocyte uroporphyrinogen decarboxylase, i.e. they had sporadic (acquired) porphyria cutanea tarda. Two (10%) of 20 patients suffering from the familial form of the disease (with low erythrocyte uroporphyrinogen decarboxylase activity) had ulcers. The examination of 105 unselected porphyriacs showed a significantly higher incidence of blood group B in comparison with the general population (23.8% vs. 16.6%). The association between the porphyriacs with ulcers and blood group B (8 of 21 examined persons) and the rare occurrence of group O (only 4 of 21) was unexpected. An association between porphyria and some of the haptoglobin types could not be established in 98 unselected patients (including those with and without ulcer). More studies are needed to substantiate the validity of blood groups and uroporphyrinogen decarboxylase as genetic markers for porphyria cutanea tarda combined with peptic ulcer.(ABSTRACT TRUNCATED AT 250 WORDS)
