Imperatae rhizoma-Hedyotis diffusa Willd. herbal pair alleviates nephrotic syndrome by integrating anti-inflammatory and hypolipidaemic effects.

BACKGROUND: Nephrotic syndrome (NS) is a common nephropathy with a complex and diverse aetiology. Both Imperatae rhizoma and Hedyotis diffusa Willd. are herbs that are widely used as medicine and functional food. In traditional Chinese medicine theory, they are used as an herbal pair (HP) to treat inflammation-related diseases in the clinic, especially disorders of the kidney. PURPOSE: This study aimed to investigate the anti-inflammatory and hypolipidaemic effects of HP in an NS rat model and provide scientific data for its clinical application. METHODS: An NS model was established by two-dose injection of Sprague-Dawley rats with adriamycin. Seven groups, including the sham, model, HP treatment (0.25, 0.5 and 1.0 g/kg/d), prednisone (positive control, 5 mg/kg/d), and atorvastatin (positive control, 4 mg/kg/d) groups, were tested. The biochemical indexes of renal function and inflammatory cytokines were determined by ELISA kits and/or qPCR assays, and the crucial protein involved in the signalling pathway were subsequently tested by qPCR and/or Western blotting. Based on specific compounds identified by LC-Q-TOF-MS, network pharmacological study was carried out. RESULTS: The levels of BUN, Scr, Upro, UA, Alb, TC, TG, and LDL-C were significantly elevated in model rats. HP treatment for four weeks improved the renal function and the dyslipidaemia by decreasing the levels of all parameters, except BUN and Scr. HP treatment (0.5 and 1.0 g/kg/d) upregulated the expression of PPARγ, CYP7b1, and LDLR in the liver, while it down-regulated PCSK9, showing a regulatory effect on lipid metabolism disorder. The levels of TNF-α and IL-1ß in the plasma and the mRNA expression of TNF-α, IL-1ß, MCP-1, and TGF-ß1 in the kidney were decreased in HP groups, revealing its anti-inflammatory effect in NS rats. The HP exerted an alleviation effect on the inflammatory response through the NF-κB pathway by inhibiting the mRNA and protein expression of p50 and p65. There were 34 compounds identified or tentatively characterized in HP. In the network pharmacological study, PPARG(PPARγ), PCSK9, RELA(p65), and NF-κB1(p50) were the top 20 targets for HP, supporting the animal experimental results. CONCLUSION: HP exhibited protective effects on NS rats. These effects might be closely related to the inhibition of NF-κB and PCSK9-LDLR and activation of the PPARγ-CYP7B1 signalling pathways.

Medical management of psoas muscle deep endometriosis: A case report.

Endometriosis is a common gynaecological pathology characterized by the presence of endometrial tissue outside the uterine cavity, and the most frequent locations of endometriosis are ovaries and posterior compartment of the pelvis. In this paper we report the case of a rare bilateral endometriosis location of posas muscle diagnosed and treated in a 25-year-old patient. This is the third case of psoas endometriosis location reported, but the first one successfully treated by hormone estrogen-progestogen treatment alone. Psoas endometriosis is a rare location and the medical management in first line can be an alternative to surgery and provide optimal patient relief.

[Drug-induced hypercalcemia].

Drug-induced hypercalcemia is caused by increased bone resorption (vitamin D and vitamin A intoxication), increased calcium absorption in the gastrointestinal tract (vitamin D intoxication, excessive intake of calcium) or increased calcium reabsorption in the renal tubules (thiazide diuretics). When vitamin D (D(2) or D(3)) intoxication develops, the hypercalcemia persists for more than several months. Therefore, short-acting active vitamin D (1alpha-OHD(3), 1,25- (OH) (2)D(3)) are clinically used. Recently, various analogs of 1,25- (OH) (2)D(3) with potent differentiation stimulating activity on keratinocytes but insufficient calcium-movilizing activity have been developed (tacalcitol, calcipotriol, 22-oxacalcitriol). However, severe hypercalcemia may develop when these ointments were abundantly applied to patients with psoriasis since the agents can be easily absorbed through the skin lesions.

Clinical findings with the oral contraceptive combination ethinylestradiol/dienogest in the Czech Republic.

The efficacy and safety of the low dose monophasic oral contraceptive (OC) combination containing 30 micrograms of ethinylestradiol (EE) and 2.0 mg of dienogest (DNG) (EE/DNG) was evaluated in a prospective, open-label, multicenter, uncontrolled, phase III trial. The trial was carried out in six hospitals by 36 investigators in the Czech Republic, and included 557 healthy women (aged 18-35 years), over 12 cycles, with a total of 6051 cycles. EE/DNG provided a reliable ovulation inhibition. The contraceptive efficacy study showed an adjusted Pearl index of 0.198 on the basis of three pregnancies occurring during 6051 cycles. EE/DNG provided good cycle control, reduced the incidence of intermenstrual bleedings, the intensity of menstrual bleeding and frequency of dysmenorrhea. Due to the antiandrogenic properties of the progestogen component DNG, EE/DNG improved androgen-related conditions, such as skin blemishes, hair greasiness and acne vulgaris. From 108 women with acne, 62 (57%) improved after the 6th cycle, and 16 (15%) were healed. Similar changes were found after cycle 12. Breast tenderness and headache were the most frequent of the common complaints due to treatment with EE/DNG. The frequency of all complaints decreased steadily over time. Only 7.7% of subjects discontinued due to adverse reactions. No thrombophlebitic events were noticed.

Parathyroid hormone-related protein in the aetiology of fibrous dysplasia of bone in the McCune Albright syndrome.

OBJECTIVE: Fibrous dysplasia, observed in bone lesions in the McCune Albright syndrome (MAS), is thought to result from abnormalities in cells of the osteogenic lineage associated with over-activation of the cAMP signalling pathway in affected cells. The aim of this study was to investigate the role of parathyroid hormone-related protein (PTHrP) in the aetiology of MAS, and to determine a possible therapeutic role for 1,25-dihydroxy vitamin D(3) (1,25(OH)(2)D(3)). DESIGN: The effects of 1,25(OH)(2)D(3) on PTHrP production and mRNA expression were determined in vitro. 1,25(OH)(2)D(3) therapy was administered to three patients with MAS. PATIENTS: Clinical data from four MAS patients (MAS1, 2, 3 and 4), and in vitro studies using bone from three MAS patients (MAS1, 2, and 3), are presented. MEASUREMENTS: Immunoradiometric assay and low-cycle number reverse transcriptase-linked PCR were used to determine PTHrP production and mRNA expression in vitro. Standard clinical biochemistry was recorded pre and post commencement of 1,25(OH)(2)D(3) treatment. RESULTS: We report the elevated secretion of PTHrP, and a concomitant rise in PTHrP mRNA expression, in cultured osteoblasts from three MAS patients. Treatment with 1,25(OH)(2)D(3) produced a dose-dependent decrease in PTHrP protein secretion and mRNA expression. Marked improvement in bone biochemistry in MAS1, 2 and 3 post treatment with 1,25(OH)(2)D(3) is documented. CONCLUSION: This study provides the first evidence suggesting that PTHrP may contribute to the aetiology of fibrous dysplasia in MAS. In addition, the therapeutic administration of 1,25(OH)92)D(3) may provide clinicians with an important new regime for symptomatic relief of bone pain and fracture in some patients with MAS.

Long-term treatment with 1 alpha-hydroxyvitamin D3 with calcium supplement in spinal osteoporotic patients.

The long-term effect of 1 alpha-hydroxyvitamin D3 and calcium lactate in osteoporotic patients was evaluated by the bone mineral density (BMD) measured at the distal one third and one sixth of the radius and by the vertebral fracture rate. Forty-five osteoporotic patients medicated for 1 to 13 years (treated group) and 11 osteoporotic patients with no medication for 1 to 3 years (control group) were compared. The BMD of the treated group remained unchanged for the first 4 (one-third site) and 6 years (one-sixth site), followed by significant decreases, whereas that of the control group decreased significantly at the second and third year. The effect on BMD was more prominent in the patients with lower initial BMD. The vertebral fracture rate of the treated group was significantly less than that in the control group at the third year. No serious side effects were recognized. Overall, we believe 1 alpha-hydroxyvitamin D3 with calcium supplement can be considered a safe and effective agent for long-term use in osteoporotic patients.

Altered mineral metabolism in glucocorticoid-induced osteopenia. Effect of 25-hydroxyvitamin D administration.

Parameters of mineral and bone metabolism were studied in 17 patients treated chronically with supraphysiologic doses of glucocorticoids. When compared to 15 matched normal subjects, the patient group exhibited similar serum 25-hydroxyvitamin D (25-OHD) levels, decreased intestinal 47Ca absorption, increased serum immunoreactive parathyroid hormone, and decreased forearm bone mass. Iliac crest bone biopsies revealed a decreased bone formation rate and increased osteoclast number. Treatment with 25-OHD (mean dose 4.03 micrograms/d) and calcium (500 mg/d) in nine patients produced a 46% increase in 47Ca absorption (P less than 0.001) and a 54% decrease in serum immunoreactive parathyroid hormone (P less than 0.001) by 3 mo. In addition, by 12 mo the treatment group exhibited (a) a 13.2 +/- 5.1% increase in metaphyseal (P less than 0.001) and a 2.1 +/- 0.4% increase in diaphyseal (P less than 0.05) forearm bone mass, and (b) significant decreases in cortical and endosteal osteoclast number. Biochemical and bone mass changes persisted through 18 mo. No significant changes in any parameter occurred in eight control patients administered calcium 100 mg/d. It is concluded that treatment with 25-OHD and calcium can significantly improve parameters of mineral and bone metabolism in patients with glucocorticoid-induced osteopenia.
