Presentation
At least 21 patients with ALS deficiency have been described presenting 16 different homozygous or compound heterozygous inactivating mutations of the IGFALS gene. [ncbi.nlm.nih.gov]
Partial gonadal dysfunction and osteoporosis may also be present. [orpha.net]
In conclusion, the results of the present study demonstrated that cetuximab blocked EGRF while concurrently inducing activation of IGF-IR and Src. [spandidos-publications.com]

Renal Insufficiency
It occurs at an overall incidence of 28 per 100,000 treatment-years, with a higher rate among patients with chronic renal insufficiency, Turner syndrome, and organic GHD, and at a lower rate in patients with ISS. [karger.com]

Glycosuria
Daily fasting and preprandial glucose measurements continued to range from 11.1 to 27.8 mmol/L and polyuria, glycosuria, and ketonuria persisted. [annals.org]
Treatment
Treatment with these agents is associated with improved glucose control and weight loss ( 7 ). [doi.org]
Experience with IGF-I treatment is limited and the risks of long-term treatment are not known. [annals.org]

Furthermore, the combination treatment reduced colony formation in MGC803 cells relative to that of treatment with cetuximab alone ( Fig. 5C ). [spandidos-publications.com]

We suggest sex steroid priming prior to provocative GH testing in prepubertal boys older than 11 and in prepubertal girls older than 10 years with AH prognosis within -2 SD of the reference population mean in order to prevent unnecessary GH treatment [karger.com]
Etiology
Etiology IGF-I deficiency is caused by homozygous mutations in the insulin-like growth factor 1 gene ( IGFI ; 12q22-q24.1). IGF-I is essential for foetal and postnatal growth, brain development and metabolism. [orpha.net]

Pathophysiology
Pathophysiology/Complications Abstract OBJECTIVE Obesity is associated with an increased risk of type 2 diabetes and cardiovascular complications. The risk depends significantly on adipose tissue distribution. [doi.org]
(Ungraded good practice statement) Pathophysiological and epidemiological observations prompt concern that GH might increase risk of malignancy during or after therapy. [karger.com]
Prevention
The main role of ALS is the extension of IGF-I half life by protecting it from degradation and preventing the passage of IGF-I to the extravascular compartment. [ncbi.nlm.nih.gov]
Conclusions Intervention trials in breast cancer prevention would greatly benefit from surrogate response markers which could predict long-term benefit. [annonc.oxfordjournals.org]
Another limitation is the lack of postintervention follow-up, which prevented assessment of the durability of our findings, in particular on adipose tissue distribution. [doi.org]
If these findings are confirmed by others, the plasma concentration of IGFBP-3 could be used to improve the accuracy of predictive models of dementia and as a potential new factor to assist in the development of prevention and treatment strategies. [nature.com]
