Experimental studies have shown that GH and IGFs stimulate cell mutagenesis and proliferation. Moreover, an association between high-normal serum IGF-I levels and an increased risk of malignancies has been suggested in the general population. Bearing this relationship in mind, the question raises whether patients with GH deficiency (GHD) replaced with GH are at increased risk of developing malignancies and whether some patients, particularly cancer survivors, are more prone to...

Background: The efficacy of recombinant human growth hormone replacement therapy (GHRT) has been demonstrated, in part, through clinical trials conducted worldwide. KIMS (Pfizer International Metabolic Database), established in 1994 and active until 2012, includes treatment outcome data and real world safety from 15 809 patients from 31 countries.Objective: The main objective of this analysis was to evaluate the long-term safety of patients with hypopitu...

Introduction: In adult patients with pituitary disease no relationship has been established between the biochemical severity of GHD and the degree of QoL impairment. Reasons may include heterogeneity of underlying pathologies, and the type of therapies received by GHD patients.Methods: The KIMS (Pfizer International Metabolic Database) database was used to focus solely on patients with non-functioning pituitary adenomas and prolactinomas treated by surge...

Objective: To identify MetS and non-MetS in subjects with adult-onset GHD before start of GH replacement and to compare prevalence of cardiovascular risk factors.Subjects and methods: MetS was defined (IDF criteria) by the obligatory presence of increased waist circumference (WC) and presence of at least two of following components: hypertension, decreased HDL-cholesterol, increased triglycerides, diabetes mellitus. The complementary group was defined as...

Of the ~12 500 GH treated subjects with adult-onset GH deficiency (GHD) in KIMS (Pfizer International Metabolic Database), 3744 with multiple pituitary hormone deficiencies (MPHD) and 367 (9%) with isolated GHD (iGHD) were eligible for baseline analysis. Subjects met the following inclusion criteria: 1) never received GH prior to entry in KIMS, 2) had stimulation tests with insulin or glucagon (GH<3 μg/l), arginine (GH<0.4 μg/l), or arginine+GHRH (cut-offs ba...

Background: Untreated GH-deficiency (GHD) in adults has been suggested to be associated with an increased prevalence of type 2 diabetes mellitus (DM). Proposed causative factors are the tendency to overweight and the insulin resistance due to central adiposity.Patients and methods: The KIMS (Pfizer International Metabolic Database) was used to evaluate the prevalence of DM in both childhood-onset (CO; n=1977; 56% males) and in adult-onset (AO; ...
