A densidade mineral óssea areal (DMO) foi baixa (média de escores Z: -3,3, -2,1, -3,7, -1,7 e) na coluna lombar, colo do fêmur, antebraço e esqueleto total, respectivamente. Esta baixa DMO areal é em parte causada pelo tamanho pequeno do osso nestes pacientes anões. Quando corrigida para o tamanho, a DMO volumétrica (densidade mineral óssea aparente) era normal ou quase normal (média de escores Z: -1.2, 0,8, e 0,8 para coluna lombar, colo do fêmur e do esqueleto total, respectivamente). É claro que será projetado na fase de evolução da fase adulta de forma muito característica. O quadro clínico da DGHA inclui sintomas e sinais clínicos inespecíficos, como fadiga, anormalidades da composição corpórea (aumento da massa gorda, diminuição da massa muscular e diminuição da densidade mineral óssea), alteração na mineralização óssea, alteração do metabolismo dos lipídios, intolerância à glicose e pior qualidade de vida. A síndrome também tem sido associada com a diminuição do desempenho cardíaco, a disfunção endotelial, o aumento dos fatores pró-coagulantes e a redução da expectativa de vida. DIGH – deficiência isolada e congênita do hormônio de crescimento (GH) causa osteoartrite no quadril, e geno valgo, sem aparente importância clínica, reduz o tamanho do osso, mas não reduz a DMOv (vertebral), da coluna lombar e quadril.

Deficiency of GH-growth hormone is a condition that affects almost all key areas of our body, some more critical, others that modify the appearance of normality of children, youth infant, adolescent and adult perpetuate through if not compensated.
Growth hormone deficiency (GHD) is a medical, endocrinology and neuroendocrinology condition caused by problems that arise in the pituitary gland, in which the body does not produce enough growth hormone (GH). Growth hormone, also called somatotropin, is a polypeptide hormone which stimulates growth and cell reproduction. A deficiency of growth hormone has a variety of different negative effects at different ages; e.g., in newborns, the primary manifestations may be hypoglycemia or micropenis, while in later infancy and early childhood, growth failure is more frequent. Deficiency also occurs in adults but is less frequent than in all stages of growth as of infant, child, youth, adolescent with end of puberty, but can have a decrease in lean body mass. Although a lack of bone mass before adulthood leading to osteoporosis, there are some circumstances that can lead infant, child and youth, to present this situation: e.g., poor nutrition, poor exercise and other factors. Deficiency in adults is rare, but may have decreased lean body mass, poor bone density, and a series of physical and psychological symptoms. Psychological symptoms include poor memory, social isolation and depression, while physical symptoms may include loss of strength, endurance and muscle. Other hormonal or glandular disorders frequently coincide with the decreased production of growth hormone. As an adult, it is normal that the pituitary gland to produce ever smaller GH and many other hormones, especially sex steroids quantities. The endocrinologists and neuroendocrinologists therefore distinguish between the natural reduction of GH levels, which comes with age and much lower levels of disability "true”, (true). Such deficiency almost always has an identifiable cause, with extremely rare adult GHD without definable cause (“idiopathic GH deficiency" ). GH works in adulthood to maintain muscle and bone mass and strength. The impact of congenital, severe disability, by untreated growth hormone (GH) in size and bone density in young adults hormone, will have significant consequences throughout the life of the patient, including the low longitudinal or linear height, and postural defects and bones training: GH and IGF-I have well recognized effects on bone elongation during development, but its importance to bone mineralization and structure during the growth phase are less well understood.
Because children with GH deficiency are usually treated with GH reposition, there is little detailed information in humans on the effects of GH deficiency on long-term bone development, this because the correct and appropriate therapy has little development time because it was fears in the 80s, as well as adjuvant treatments and sampling still not reliable for such a serious situation. The recently described syndrome of genetic GHRH receptor deficiency in Pakistan (dwarfism of Sindh) provides a unique opportunity to examine the issue of GH deficiency in bone development, because affected patients have severe congenital isolated GH deficiency, who had never been treated by because of social reasons. Dual energy x-ray absorptiometry scans were performed in four male adults (age between 23-30 years) to address the issue of bone mineralization. Areal bone mineral density (BMD) was low (mean Z scores: -3.3, -2.1, -3.7, -1.7 and) at the lumbar spine, femoral neck, forearm and skeleton total respectively. This low areal BMD is partly caused by the small bone size in these patients dwarves. When corrected for size, volumetric BMD (bone mineral apparent density) was normal to near normal (mean Z scores: -1.2, 0.8, and 0.8 for the lumbar spine, femoral neck and total skeleton, respectively). Of course that will be projected on stage in the evolution of adulthood so very characteristic. The clinical picture of DGHA includes unspecific symptoms and clinical signs, such as fatigue, abnormalities in body composition (increased fat mass, decreased muscle mass and decreased bone mineral density), change in bone mineralization, metabolism of lipids, in intolerance glucose and quality of life.
The syndrome has also been associated with decreased cardiac performance, endothelial dysfunction, increased procoagulant factors and reduced life expectancy. IDGH-isolated and congenital deficiency of growth hormone (GH) causes osteoarthritis in the hip, and genu valgus, no apparent clinical importance, reduces the size of the bone, but does not reduce the BMDv (vertebral) of the hip and lumbar spine.
