Consensus guidelines for the diagnosis and treatment of adults with growth hormone deficiency: Summary statement of the growth hormone research society workshop on adult growth hormone deficiency

Based on the increasing body of evidence that adults with GH deficiency (somatotropin deficiency) have impaired health that improves with GH replacement, many countries have already approved the use of GH for replacement therapy in adults with GH deficiency. To ensure that patients are appropriately identified and treated, the Growth Hormone Research Society (GRS) convened a workshop on April 14–17, 1997, in Port Stephens, Australia, to formulate consensus guidelines for the diagnosis and treatment of adults with GH deficiency. The GRS invited scientists with expertise in the field, representatives from industry involved in the manufacture of recombinant human GH, and representatives from health authorities from a number of countries to attend the workshop, all of whom contributed to the consensus guidelines as detailed below

Consensus guidelines for the diagnosis and treatment of growth hormone (GH) deficiency in childhood and adolescence: Summary statement of the GH research society

The diagnosis and treatment of GH deficiency (GHD) during childhood and adolescence have been the subject of much controversy (1–3). To insure that patients are appropriately identified and treated, the GH Research Society (GRS) convened a workshop, on October 17–21 1999, in Eilat, Israel. The objectives of this workshop were to formulate consensus guidelines for the diagnosis and treatment of children and adolescents with GHD. The GRS invited clinicians and scientists with expertise in the field, representatives from industries involved in the manufacturing of recombinant GH, and representatives from health authorities from a number of countries to attend the workshop. All of them contributed to the consensus guidelines as detailed below

Management of acromegaly in Latin America: expert panel recommendations

Although there are international guidelines orienting physicians on how to manage patients with acromegaly, such guidelines should be adapted for use in distinct regions of the world. A panel of neuroendocrinologists convened in Mexico City in August of 2007 to discuss specific considerations in Latin America. Of major discussion was the laboratory evaluation of acromegaly, which requires the use of appropriate tests and the adoption of local institutional standards. As a general rule to ensure diagnosis, the patient’s GH level during an oral glucose tolerance test and IGF-1 level should be evaluated. Furthermore, to guide treatment decisions, both GH and IGF-1 assessments are required. The treatment of patients with acromegaly in Latin America is influenced by local issues of cost, availability and expertise of pituitary neurosurgeons, which should dictate therapeutic choices. Such treatment has undergone profound changes because of the introduction of effective medical interventions that may be used after surgical debulking or as first-line medical therapy in selected cases. Surgical resection remains the mainstay of therapy for small pituitary adenomas (microadenomas), potentially resectable macroadenomas and invasive adenomas causing visual defects. Radiotherapy may be indicated in selected cases when no disease control is achieved despite optimal surgical debulking and medical therapy, when there is no access to somatostatin analogues, or when local issues of cost preclude other therapies. Since not all the diagnostic tools and treatment options are available in all Latin American countries, physicians need to adapt their clinical management decisions to the available local resources and therapeutic options

Growth And The Growth Hormone-Insulin Like Growth Factor 1 Axis In Children With Chronic Inflammation:Current Evidence, Gaps In Knowledge And Future Directions

Growth failure is frequently encountered in children with chronic inflammatory conditions like juvenile idiopathic arthritis, inflammatory bowel disease and cystic fibrosis. Delayed puberty and attenuated pubertal growth spurt is often seen during adolescence. The underlying inflammatory state mediated by pro-inflammatory cytokines, prolonged use of glucocorticoid and suboptimal nutrition contribute to growth failure and pubertal abnormalities. These factors can impair growth by their effects on the growth hormone-insulin like growth factor axis and also directly at the level of the growth plate via alterations in chondrogenesis and local growth factor signaling. Recent studies on the impact of cytokines and glucocorticoid on the growth plate studies further advanced our understanding of growth failure in chronic disease and provided a biological rationale of growth promotion. Targeting cytokines using biologic therapy may lead to improvement of growth in some of these children but approximately one third continue to grow slowly. There is increasing evidence that the use of relatively high dose recombinant human growth hormone may lead to partial catch up growth in chronic inflammatory conditions, although long term follow-up data is currently limited. In this review, we comprehensively review the growth abnormalities in children with juvenile idiopathic arthritis, inflammatory bowel disease and cystic fibrosis, systemic abnormalities of the growth hormone-insulin like growth factor axis and growth plate perturbations. We also systematically reviewed all the current published studies of recombinant human growth hormone in these conditions and discuss the role of recombinant human insulin like growth factor-1
