Normal serum insulin-like m t&x-l (IGF-I) levels arc imponaat for aoabolism in adult homaos. In cirrhosii the growth hormone (GH)-IGF-I axis is demqd with low serum IGF-1 possibly dot to GH rcsistaacc. The catabolic stale can compmmisc swccssful liver transplantation.

the extract increased the villus small bowel up to 56% above
surface length index of the that in methotrexate-injected
controls. The crypt area index was also significantly increased 64% in the jejunum. Sucrase activity was significantly higher in the ileum (270%) but not the jejunum. Bacterial translocation was significantly reduced in rats receiving oral whey extract. We conclude that oral administralion of a whey growth factor extract reduces methotrexate damage in the small bowel, suggesting clinical applications in gut mucositis.
HORMONE (GH) THERAPY CAN IMPROVE GROWTH ECONOMY IN MALNOURISHED CIRRHOTIC PROTEIN PATIENTS &&j?onv J. Donaghy. -Richard J. Floss, Claire Wicks, ‘Sian Cwyfan Hughes, ‘Jeffrey Holly,Alexander E. Gimsonand Roger Williams. Institute of Liver Studies, Kings College Hospital and ‘Dept. of Endocrinology, St Ballholorwws Hospital, London, UK. Cirrhosis is associated with protein calorie malnutrition and GH resistance, with low circulating levels of insulin-like growth factor-l (IGF-I) and its major binding protein IGFBP-3. We conducted a double blind, plqcebo controlled trial of GH therapy in 20 cirrhotic patients to assess reversibility of GH resistance, subsequent impact on protein economy and safety. Patients were treated with daily SC injections of either GH (0.25 IU / kg) or placebo for 7 days, after a 3 day baseline period. Levels of GH,
IGF-I and IGFBP-3 were measured by RIA, and urinary nitrogen by the Kjeldahl technique. Serum IGF-I levels rose significantly only in the GH group from mean 69.2fSE 7 @ml on day 1 to 170.6&46 on day 11 (~~0.05) although this response was attenuated in comparison to that seen in normals. IGFBP-3 levels also rose significantly from 1.65f0.3 mg/L to 2.94f0.6 (~~0.005) in the GH group. Cumulative daily nitrogen balance improved significantly from 1.12f1.4 g/day (day 1) to 27.38f12.5 (day 10) in the GH group (~~0.05) but,no significant change was seen in the placebo group -1.76fl.23 (day 1) to 3.95f7.65 (day 10). We conclude that GH therapy was able to partially overcome the GH resistance of cirrhosis, increasing production of IGF-I and IGFBP-3 and effecting significant improvement in nitrogen balance. GH may have an important role in the treatment of malnourished cirrhotics.
