Emerging cardiovascular risk factors/markers such as proinflammatory cytokines , C-reactive protein , and adipokines are also increased in GHD patients .
Increased cardiovascular morbidity and mortality have also been reported in GHD .
GH treatment has been shown to improve both traditional and emerging cardiovascular risk factors and markers .
The GHD population may be considered at high cardiovascular risk , and GH substitution may be expected to bring an added value to patients with hypopituitarism in terms of cardiovascular protection .
CONTEXT GH deficiency ( GHD ) of the adult is a clinical condition characterized by the presence of several traditional and emerging cardiovascular risk factors that can significantly increase cardiovascular morbidity and mortality .
It is still an open issue whether GH replacement is able not only to improve cardiovascular risk factors but also to decrease cardiovascular morbidity and mortality .
EVIDENCE SYNTHESIS In untreated GHD , cardiovascular risk is increased due to abnormal lipid profile ( increased total and low-density lipoprotein cholesterol , increased triglycerides , and reduced high-density lipoprotein cholesterol ) and impaired glucose metabolism .
Evaluation of coagulation and fibrinolytic parameters in adult onset GH deficiency and the effects of GH replacement therapy: a placebo controlled study.
OBJECTIVE Increased cardiovascular mortality/morbidity observed in patients with hypopituitarism is ascribed to growth hormone deficiency ( GHD ) because of its unfavorable cardiovascular risk profile . Abnormalities in the coagulation system may also contribute to increased cardiovascular morbidity/mortality . To get a better insight into the role of hemostasis in GHD we assessed several hemostatic markers at baseline and after 6 months of GH replacement therapy ( GHRT ) . DESIGN - PATIENTS : Nineteen patients with adult onset GHD were enrolled ( twelve patients into the treatment and seven patients into the placebo group )  into the study . Platelet count , collagen/epinephrine closure time , collagen/ADP closure time , fibrinogen , prothrombin time ( PT ) , activated partial thromboplastin time ( aPTT ) , antithrombin III ( AT III ) , protein C activity , protein S activity , lupus anticoagulant , antiphospholipid antibody immunoglobulin M , and antiphospholipid antibody immunoglobulin G were measured at baseline and 6 months after treatment . RESULTS The investigated parameters in the groups were similar at baseline except for low protein S ( PS ) activity . Protein S deficiency was observed in three of the patients in the GH treatment group at baseline , however the PS activity values normalized following GHRT .  AT III and protein C activities decreased when compared to baseline values in the treatment group but not in the placebo group . CONCLUSIONS We observed protein S deficiency more frequent than seen in the general population and normalization of protein S activity and decreases , in other natural anticoagulants following GHRT . Further studies are required to underst and the impact of these changes in cardiovascular morbidity and mortality in this patient population
