During the year 2000, several original studies were published regarding the metabolic effects of growth hormone therapy in pediatric patients. Pharmacologic doses of growth hormone were rarely associated with abnormalities in glucose tolerance in children with intrauterine growth retardation and Turner syndrome; however, serum insulin levels were elevated. A report from the Pharmacia International Growth Study database suggested a possible increase in type 2 diabetes in growth hormone-treated patients, indicating the need for continued surveillance for this condition. Growth hormone therapy increased markers of bone turnover and bone mineral density in children with chronic renal failure and Prader-Willi syndrome. In Prader-Willi syndrome, 2 years of growth hormone therapy also induced a sustained decrease in body fat, improvement in strength and physical skills, and increased lean body mass. Serum leptin, a reflection of body fat, declined with growth hormone therapy in a dose-dependent manner in intrauterine growth retardation children; the magnitude of the decline correlated with linear growth response. Skin is a target organ for growth hormone in children; growth hormone increased dermal thickness and reduced skin stiffness in growth hormone-deficient children. Reassuring data were published regarding the risk of tumor recurrence and mortality in children with brain tumors treated with growth hormone. Growth hormone administered to short children prior to kidney transplantation did not have adverse effects on subsequent graft survival or number of rejection episodes.

Aquaporin-2 (AQP-2) is known to be expressed in the renal collecting duct cells and participates in urinary concentration in response to arginine vasopressin (AVP). The present study was undertaken to determine whether progression of renal dysfunction affects urinary excretion of AQP-2 in diabetic nephropathy. The study was composed of 8 control subjects and 14 patients with type 2 diabetes classified into two groups according to serum creatinine level (cut-off point; 1.5 mg/dl). After an 8-hour water deprivation, both urinary osmolality (U(osm)) and urinary excretion of AQP-2 significantly decreased in the diabetic patients with chronic renal failure as compared to the control subjects (p < 0.0001, p < 0.05, respectively). After a water load (10 ml/kg), no differences were found in plasma osmolality (P(osm)), AVP levels and U(osm), whereas urinary excretion of AQP-2 significantly decreased in the patients with chronic renal failure as compared to the control subjects (p < 0.05). These results indicate that the decreased urinary excretion of AQP-2 in diabetic nephropathy is due to the impaired cellular signaling of AVP in collecting duct cells, which may be partly involved in the urinary concentrating defect in renal failure.

Adiponectin, also called GBP-28, apM1, AdipoQ and Acrp30, is a novel adipose tIssue-specific protein that has structural homology to collagen VIII and X and complement factor C1q, and that circulates in human plasma at high levels. It is one of the physiologically active polypeptides secreted by adipose tIssue, whose multiple functions have started to be understood in the last few Years.A reduction in adiponectin expression is associated with insulin resistance in some animal models. Administration of adiponectin has been accompanied by a reduction in plasma glucose and an increase in insulin sensitivity. In addition, thiazolidinediones, drugs that enhance insulin sensitivity through stimulation of the peroxisome proliferator-activated receptor-gamma, increase plasma adiponectin and mRNA levels in mice. On the other hand, this adipocyte protein seems to play a protective role in experimental models of vascular injury. In humans, adiponectin levels are inversely related to the degree of adiposity and positively associated with insulin sensitivity both in healthy subjects and in diabetic patients. Plasma adiponectin levels have been reported to be decreased in some insulin-resistant states, such as obesity and type 2 diabetes mellitus, and also in patients with coronary artery disease. On the contrary, chronic renal failure, type 1 diabetes and anorexia nervosa are associated with increased plasma adiponectin levels. Concentrations of plasma adiponectin have been shown to correlate negatively with glucose, insulin, triglyceride levels and body mass index, and positively with high-density lipoprotein-cholesterol levels and insulin-stimulated glucose disposal. Weight loss and therapy with thiazolidinediones increased endogenous adiponectin production in humans. Adiponectin increases insulin sensitivity by increasing tIssue fat oxidation, resulting in reduced circulating fatty acid levels and reduced intracellular triglyceride contents in liver and muscle. This protein also suppresses the expression of adhesion molecules in vascular endothelial cells and cytokine production from macrophages, thus inhibiting the inflammatory processes that occur during the early phases of atherosclerosis. In view of these data, it is possible that hypoadiponectinemia may play a role in the development of atherosclerotic vascular disease. In summary, the ability of adiponectin to increase insulin sensitivity in conjunction with its anti-inflammatory and anti-atherogenic properties have made this novel adipocytokine a promising therapeutic tool for the future, with potential applications in states associated with low plasma adiponectin levels.

The prevalence of hypertension in patients with chronic renal insufficiency is high. In the stage of renal insufficiency it is 60% and in conservatively terminal renal failure it is as high as 90%. After the initiation of dialyzation treatment it declines temporarily, it is higher during chronic haemodialysis (50-80%) and lower in continuous ambulatory peritoneal dialysis (30%). After transplantation it is recorded in 70-80% recipients of a renal graft. Among the causes of renal hypertension in subjects with conservatively treated chronic renal insufficiency at present secondary renal impairment is increasing--in type 2 diabetes and also renal vascular affection due to atherosclerotic changes and essential arterial hypertension. Approximately 30% of patients where chronic dialyzation treatment is started, come "from the street". In the pathogenesis of renal hypertension sodium retention is involved with volume expansion and an impaired ratio of the formation of vasoactive (vasopressor and vasodepressor) substances. In chronic renal failure the volume component of hypertension predominates markedly. The causes of the development of hypertension after renal transplantation are multifactorial and are most closely associated with immunosuppressive treatment and graft rejection. Pharmacological treatment of renal hypertension prefers inhibitors of the angiotensin converting enzyme (possibly angiotensin II antagonists) because of their concurrent renoprotective action. In the stage of renal insufficiency they call for reduced doses and combination with other antihypertensive agents. The objective of treatment is to achieve a blood pressure < 130/80 mm Hg. In chronic dialyzation treatment the main therapeutic provision in hypertension is adjustment of the volume of extracellular fluid by regime provisions and effective haemoelimination treatment. Calcium blockers are useful in particular in the treatment of hypertension in haemodialyzed subjects and in hypertension after renal transplantation.

We present a case report of the anaesthetic management of a 77-year-old man requiring endovascular thoracic stent graft repair. The patient had a history of poorly controlled type II diabetes mellitus and chronic renal failure. Chest X-ray and CT scan showed a right pleural effusion, generalized emphysema and an enlarged thyroid extending into the upper mediastinum, compromising the tracheal lumen. Endovascular stent graft repair was successfully performed under epidural anaesthesia and intravenous sedation.

Somatomedin-1 binding protein-3 [insulin-like growth factor-1 binding protein-3, SomatoKine] is a recombinant complex of insulin-like growth factor-1 (rhIGF-1) and binding protein-3 (IGFBP-3), which is the major circulating somatomedin (insulin-like growth factor) binding protein; binding protein-3 regulates the delivery of somatomedin-1 to target tissues. Somatomedin-1 binding protein-3 has potential as replacement therapy for somatomedin-1 which may become depleted in indications such as major surgery, organ damage/failure and traumatic injury, resulting in catabolism. It also has potential for the treatment of osteoporosis; diseases associated with protein wasting including chronic renal failure, cachexia and severe trauma; and to attenuate cardiac dysfunction in a variety of disease states, including after severe burn trauma. Combined therapy with somatomedin-1 and somatomedin-1 binding protein-3 would prolong the duration of action of somatomedin-1 and would reduce or eliminate some of the undesirable effects associated with somatomedin-1 monotherapy. Somatomedin-1 is usually linked to binding protein-3 in the normal state of the body, and particular proteases clip them apart in response to stresses and release somatomedin-1 as needed. Therefore, somatomedin-1 binding protein-3 is a self-dosing system and SomatoKine would augment the natural supply of these linked compounds. Somatomedin-1 binding protein-3 was developed by Celtrix using its proprietary recombinant protein production technology. Subsequently, Celtrix was acquired by Insmed Pharmaceuticals on June 1 2000. Insmed and Avecia, UK, have signed an agreement for the manufacturing of SomatoKine and its components, IGF-1 and binding protein-3. CGMP clinical production of SomatoKine and its components will be done in Avecia's Advanced Biologics Centre, Billingham, UK, which manufactures recombinant-based medicines and vaccines with a capacity of up to 1000 litres. In 2003, manufacturing of SomatoKine is planned to move to Avecia's larger facility with a capacity of 10 000 litres. Somatomedin-1 binding protein-3 was originally licenced to Welfide for Japan. On October 1 2001, Welfide Corporation merged with Mitsubishi-Tokyo Pharmaceuticals to form Mitsubishi Pharma Corporation. The new company is a subsidiary of Mitsubishi Chemical. In April 2003 Insmed initiated a named patient programme in Europe, that will make available somatomedin-1 binding protein-3 for the treatment of growth hormone insensitivity syndrome (GHIS)--Laron syndrome. The treatment of patients was initiated in Scandinavia, with authorisation pending in several other European countries. Somatomedin-1 binding protein-3 will be made available to those GHIS patients who, in the opinion of their doctor, may benefit from IGF-1 therapy. At precommercial scale quantities, the drug will be available on a limited basis. Safety data generated from the named patient programme will be used to support marketing applications in 2004. A phase II dose-ranging study in children with GHIS was completed at Saint Bartholomew's and the Royal London School of Medicine, London, UK. A single dose of somatomedin-1 binding protein-3 delivered the same amount of IGF-1 as two daily injections of unbound IGF-1. There were no adverse events reported. GHIS is a genetic condition in which patients do not produce adequate quantities of IGF because of a failure to respond to the growth hormone signal. This results in a slower growth rate and short stature. Insmed has acquired an exclusive licence to Pharmacia's regulatory filings concerning yeast-derived IGF-1. These filings were used by Pharmacia to receive marketing approvals in several European countries and also in the investigational New Drug Application with the US FDA. This licence will facilitate the development of SomatoKine for the treatment of children with GHIS. In January 2003, Insmed announced positive results from a double-blind, placebo-controlled, dose-ranging study of SomatoKine in adolescent patients with type 1 diabetes mellitus redolescent patients with type 1 diabetes mellitus receiving insulin therapy. The study was conducted at the University of Cambridge, Cambridge, UK, under the supervision of Professor D. Dunger. It has also been granted orphan drug status for the treatment of GHIS--Laron syndrome in the US and in Europe. Celtrix has been granted 11 US patents for its recombinant protein production technology, which it used for developing somatomedin-1 binding protein-3. Subsequently, Celtrix was acquired by Insmed Pharmaceuticals on June 1 2000. Following the acquisition, Insmed announced that it intends to maintain the US rights to Celtrix's products portfolio. These US patents will expire between 2010 through 2017. Insmed is holding a US patent (expires in 2019) for the use of SomatoKine in the treatment of both type 1 and type 2 diabetes mellitus.

The derangement of glucose metabolism is found frequently in all forms of hyperparathyroidism. Both in primary (PHPT) and secondary hyperparathyroidism (SHPT) PTH excess is thought to be involved in deteriorating insulin sensitivity and secretion though their different clinical and pathophysiological conditions. In PHPT these abnormalities are related to a high frequency of Type 2 diabetes mellitus and also impaired glucose tolerance according to recent clinical studies, without differences between symptomatic and asymptomatic clinical presentation. In chronic renal failure (CRF), the disorders of glucose metabolism due to SHPT do not bear an increased risk for diabetes whereas they seem to be involved in the progression of atherosclerotic vascular damage which connotes CRF. Moreover, clinical and experimental studies have shown that vitamin D deficiency associated with glucose metabolism abnormalities favors the development of the metabolic syndrome. The potential for metabolic and cardiovascular harm related to hyperparathyroidism, especially PHPT, is the most interesting issue for clinical endocrinologists. This short review of the clinical and pathophysiological data of literature on glucose homeostasis disorders in hyperparathyroidism focuses on its potential clinical and therapeutic impact, particularly in the management of PHPT.

Systemic lupus erythematosus (SLE) is a multifactorial polysystemic autoimmune disorder. Although life expectance in SLE has been improved by adequate immune suppressive therapy, the importance of chronic renal failure has not been reduced. Among late complications of the disease accelerated atherosclerosis attempts increasing attention. Dyslipoproteinemia and increased concentration of lipoproteins are important risk factors of atherosclerotic cardiovascular complication in SLE. Serum lipid parameters of 50 patients with lupus were examined in the present work. Thirty patients had histologically proven lupus nephritis (LN+), while the other group did not have renal involvement (LN-). Serum triglyceride, total cholesterol, LDL-C and apolipoprotein B (apoB) concentrations were significantly higher in the lupus nephritis (LN+) group. On the other hand, HDL-C and apoAI levels were also elevated in patients with LN. As a consequence of that, LDL-C/HDL-C and the apoB/apoAI ratios did not differ between patients with or without kidney involvement. This concluded the authors to measure the concentration of lipoprotein (a) in SLE patients, as Lp(a) is known to be an independent risk factor of atherosclerosis. Results indicated a significantly increased Lp(a) concentration in patients with lupus nephritis as compared to the LN- group. All but 2 patients without kidney involvement had lower than 100 mg/L Lp(a) concentration, while 27% of patients with lupus nephritis has an Lp(a) level between 100-300 mg/L. Further more, Lp(a) concentration was higher than 300 mg/L in 13% of the LN+ group. In a good correlation of these observations patients with nephritis suffered more frequently from deep venous thrombosis and ischaemic heart disease. The frequencies of hypertension and non-insulin dependent diabetes mellitus were slightly elevated in patients with nephritis. Present results suggest the importance of elevated lipoprotein (a) concentration in patients with lupus nephritis, further increasing the risk of athero-thrombotic cardiovascular complications.

The prevalence of chronic renal failure (CRF) in 460 patients with diabetes mellitus attending the diabetic outpatient clinic at the University Hospital of the West Indies in Jamaica was determined from a review of medical records. The prevalence of CRF was 10% (39/386) in the diabetic clinic population. Significant positive associations with CRF were found with male gender (20/98, 20% vs 19/287, 7%; odds ratio (OR), 3.24; p = 0.001); age 60 years and older (22/162; 14% vs 17/221, 8%; OR, 2.01; p = 0.04); fasting blood glucose concentrations exceeding 8.0 mmol/L (22/162, 13% vs 12/182, 7%; OR, 2.08; p = 0.05); the presence of significant proteinuria as a marker for outcome (13/39, 33% vs 48/346, 14%; OR, 3.60; p = 0.02) and peripheral vascular disease (6/20, 30% vs 139/386, 10%; OR, 4.75; p = 0.005). The prevalence of CRF did not differ significantly between patients with Type 1 and Type 2 diabetes mellitus. Also, the presence of CRF was not significantly associated with duration of diabetes mellitus, type of hypoglycaemic agents used, or history of hypertension. However, the presence of persistent proteinuria was significantly associated with duration of diabetes mellitus exceeding five years (46/255, 17% vs 11/149, 7%; OR, 2.52; p = 0.005) and a history of hypertension (41/235, 17% vs 20/198, 10%; OR, 1.88; p = 0.03) but not with age or gender. This study emphasizes the need to evaluate patients with diabetes mellitus for renal impairment so that intervention strategies may be adopted early to delay progression to endstage renal disease.

A 59-year-old woman with chronic renal failure due to type 2 diabetes mellitus (DM) is presented. Her father and a brother had a history of brain tumor. Her blood urea nitrogen and serum creatinine levels were 102 mg/dl and 4.5 mg/dl, respectively. Her serum Ca(2+) and Pi were within the normal range (9.4 mg/dl and 5.4 mg/dl, respectively). Her intact parathyroid hormone (PTH) level was 1 730 000 pg/ml. A (99m)Tc-methoxy-isobutylisonitrile scintigraphy showed high uptake in three parathyroid glands. A magnetic resonance image showed microadenoma in the pituitary gland. The serum gastrin level was high. Genetic examination revealed a mutation of the MEN1 gene (894-9 G --> A). From these findings, she was diagnosed with multiple endocrine neoplasia (MEN) type 1. Subsequently, a parathyroidectomy was performed successfully, a parathyroid gland was transplanted to her right forearm, and her serum Ca(2+) level was controlled at 8.5-9.0 mg/dl. It is very important to identify MEN1 if an end-stage renal disease (ESRD) patient has hyperparathyroidism with multigland involvement. Examination of the MEN1 gene may be valuable to make an accurate diagnosis and choose the appropriate therapy in some ESRD patients with hyperparathyroidism.
