High-speed gas chromatography with direct resistively-heated column (ultra fast module-GC)-separation measure (S) and other chromatographic parameters under different analysis conditions for samples of different complexities and volatilities.

The influence of GC speed on the separation capability of a chromatographic system is reported measuring a series of parameters including separation measure (S), peak capacity (n), peak width (w), analysis time, t(b) (determined on the last eluting compound) and separation measure/analysis time ratio (S/t(b)) determined by analyzing a bergamot essential oil sample and a standard mixture of pesticides. Conventional GC, fast GC (with 10 m (FGC10) and 5 m (FGC5) narrow-bore columns), and direct resistively-heated ultra fast module-GC (UFM-GC) were the GC speed approaches used. The influence of different heating rates with a constant flow for FGC5, FGC 10, and UFM-GC and with variable flows for UFM-GC on S, n, w, S/t(b), and t(b) was also studied. The results of this study show that: (a) separation capability of the chromatographic system (i.e. S and n) and analysis time depend on the GC approaches. Within each GC approach, S and n and analysis time depend on the heating rates, although to a different extent, and S and n decrease much less than the gain in analysis time, in particular when fast heating rates are applied; (b) in UFM-GC, the loss of separation capability with heating rate can also be partially compensated by the choice of an appropriate flow rate that, within each heating rate, may contribute to increase S while reducing t(b); (c) within a specific GC approach, the chromatographic system (column and stationary phase) and conditions (heating and flow rates) must be such to achieve a suitable S-value when two analytes must be separated with a given resolution in a minimum analysis time.

Reduction of cardiovascular morbidity and mortality in type 2 diabetes. A rational approach to hypoglycemic therapy.

Type 2 diabetes mellitus is the single most important risk factor for the development of coronary artery disease. Unfortunately, the traditional therapeutic strategies for the treatment of hyperglycemia have proven to be ineffective in preventing cardiovascular complications. In recent years the number of available hypoglycemic agents has increased and considerable progress has been made regarding the comprehension of the pathophysiology of diabetes and its vascular complications. In the present article we firstly present benefits and risks of intensive vs standard hypoglycemic intervention, and the pros and cons of therapy targeted to postprandial hyperglycemia. Secondly, we discuss the cardiovascular effects of sulfonylurea agents and insulin, focusing on the role of intensive insulin treatment in the context of acute coronary syndromes. Thirdly, we review the epidemiological, clinical and experimental evidence linking insulin resistance and cardiovascular disease. Finally, we present the rationale and the role of metformin and thiazolidinedionetherapy in the prevention of cardiovascular complications. We conclude that the optimal use of the full spectrum of hypoglycemic agents has the potential to play a key role in the prevention of diabetes-related macrovascular complications.

Breakthrough pain characteristics and syndromes in patients with cancer pain. An international survey.

Breakthrough pain (BKP) is a transitory flare of pain that occurs on a background of relatively well controlled baseline pain. Previous surveys have found that BKP is highly prevalent among patients with cancer pain and predicts more severe pain, pain-related distress and functional impairment, and relatively poor quality of life. An international group of investigators assembled by a task force of the International Association for the Study of Pain (IASP) evaluated the prevalence and characteristics of BKP as part of a prospective, cross-sectional survey of cancer pain. Fifty-eight clinicians in 24 countries evaluated a total of 1095 patients with cancer pain using patient-rated items from the Brief Pain Inventory (BPI) and observer-rated measures. The observer-rated information included demographic and tumor-related data, the occurrence of BKP, and responses on checklists of pain syndromes and pathophysiologies. The clinicians reported BKP in 64.8% of patients. Physicians from English-speaking countries were significantly more likely to report BKP than other physicians. BKP was associated with higher pain scores and functional interference on the BPI. Multivariate analysis showed an independent association of BKP with the presence of more than one pain, a vertebral pain syndrome, pain due to plexopathy, and English-speaking country. These data confirm the high prevalence of BKP, its association with more severe pain and functional impairment, and its relationship to specific cancer pain syndromes. Further studies are needed to characterize subtypes of BKP. The uneven distribution of BKP reporting across pain specialists from different countries suggests that more standardized methods for diagnosing BKP are needed.

Metalloproteinases 2 and 9 are increased in plasma of patients with heart failure.

BACKGROUND: Progression of heart failure is associated with interstitial changes in the heart and in areas distant from the heart. Enhanced expression of metalloproteinases 2 and 9 and of metalloproteinases tissue inhibitors 1 and 2 have been found in ventricular tissue of patients with heart failure. Our aim was to determine whether increased activity of metalloproteinase-2, metalloproteinase-9 and of metalloproteinases tissue inhibitor-1 and metalloproteinases tissue inhibitor-2 were also present in plasma of patients with heart failure. DESIGN: Levels of metalloproteinase-2, metalloproteinase-9 and of metalloproteinase tissue inhibitor-1 and metalloproteinases tissue inhibitor-2 were measured in venous blood of 51 patients with heart failure, and were compared with levels of 52 control subjects. Samples collected from patients and control subjects were assayed for gelatinolytic activity (zymography) and for protein levels. RESULTS: Compared with the control subjects, the patients with heart failure had a significant increase in activity levels (mean +/- SE, ng mL(-1)) of prometalloproteinase-9 (95.1+/-11.2 and 38.9+/-4.5*), activ. metalloproteinase-9 (18.4+/-2.5 and 10.9+/-1.3*), and of prometalloproteinase-2 (571.4+/-26.1 and 456.8+/-21.1*) (respectively: patients and control subjects; *P<0.05). Metalloproteinases tissue inhibitor-1, but not metalloproteinases tissue inhibitor-2 protein values were higher in the patients. Among the patients, clinical status and New York Heart Association (NYHA) class did not correlate with the metalloproteinase concentrations. Positive correlations with left ventricular volumes, and negative correlations with lipid values were obtained for prometalloproteinase-2; positive correlations with total number of white cells and neutrophils were obtained for prometalloproteinase-9; and positive correlations with lactate dehydrogenase, serum fibrinogen, aspartate transaminases were found for activ. metalloproteinase-9. CONCLUSIONS: Regardless of the clinical phase of heart failure, elevated levels of activity and of circulating metalloproteinase protein levels suggest the presence of persistent extracellular remodeling in patients with heart failure.

High doses of atorvastatin do not affect activity of prothrombinase in patients with acute coronary syndromes.

Membrane-dependent coagulation processes play a key role in acute coronary syndromes (ACS), where the generation of thrombin depends on the complex of activated factors X and V (prothrombinase complex) assembled on activated platelets. The aim of the present study was to evaluate prothrombinase activity in patients with ACS and to examine the effect of treatment with 80 mg/day atorvastatin on prothrombinase activity. Blood samples were obtained at admission from 22 patients with ACS, and then again at 2 weeks and at 16 weeks after double-blind randomization to either placebo or atorvastatin. Prothrombinase activity was evaluated by measuring the generation of thrombin by in vitro reconstructed thrombi, and also by measuring plasma levels of prothrombin fragment F1 + 2. Twenty age-matched subjects with stable angina and 11 without coronary disease were used as controls. At admission, prothrombinase activity and F1 + 2 were significantly higher in ACS patients than in controls. Prothrombinase activity was still high at 2 weeks while it returned to normal levels at 16 weeks. F1 + 2 remained high both at 2 and at 16 weeks. Our data indicate that prothrombinase activity is high in patients with ACS, and that it is not affected by high-dose atorvastatin.

Conventional inner diameter short capillary columns: an approach to speeding up gas chromatographic analysis of medium complexity samples.

Short capillary columns (5 m) with 0.25 mm inner diameter (I.D.) are applied to the GC analysis of medium complexity samples (up to 30 components) with the aim of shortening analysis time. This approach is complementary to fast GC with narrow-bore columns and is based on compensating the lower efficiency of short columns with conventional I.D.'s (0.25-0.32 mm) by using a stationary phase selectivity suitable to separate the components of the sample under investigation, so that the required resolution power is achieved but, at the same time, the analysis time is shortened. The qualitative and quantitative effectiveness of this approach is demonstrated through the analysis of: essential oils with different compositions (chamomile and rosemary), low-volatility triterpenes in a plant extract (Maytenus aquifolium and M. ilicfolium), thermolabile pyrethrins in a Pyrethrum extract, and a mixture of pesticides applied to protect medicinal plant crops. In all examples, GC analysis was five to ten times faster than with conventional columns.

Quality of life assessment and outcome of palliative care.

Quality of life (QoL) assessment is crucial for the evaluation of palliative care outcome. In this paper, our methodological approach was based on the creation of summary measures. Fifty-eight Palliative Care Units (PCUs) in Italy participated in the study. Each PCU randomly selected patients to be 'evaluated' among the consecutively 'registered' patients. At baseline (first visit) and each week the patient was asked to fill in a QoL questionnaire, the Therapy Impact Questionnaire (TIQ). Short-survivors (<7 days) were not included in the QoL study. The random sample of patients (n = 601) was highly representative of the general patient population cared for by the PCUs in Italy. The median survival was 37.9 days. We collected 3546 TIQ, 71.4 % completed by the patients. A Summary Measure Outcome score was calculated for 409 patients (81% of the patients included in the QoL study). The results of this national study showed that cooperative clinical research in palliative care is possible and QoL measures can be used to assess the outcome.

Ultrasound biomicroscopy and intraocular-pressure-lowering mechanisms of deep sclerectomy with reticulated hyaluronic acid implant.

PURPOSE: To evaluate the anatomic characteristics and intraocular pressure (IOP) lowering mechanisms of deep sclerectomy with reticulated hyaluronic acid implant (DS with RHAI) using ultrasound biomicroscopy (UBM). SETTING: Eye Clinic, Department of Neurological and Vision Sciences, University of Verona, Verona, Italy. METHODS: Thirty patients with primary open-angle glaucoma not controlled by medical therapy had DS with RHAI in 1 eye. A complete ocular examination and UBM study were performed 1, 3, 6, and 12 months postoperatively and thereafter at 6 month intervals. Eleven parameters were evaluated, the most important of which were IOP, surgical success in lowering IOP to 21 mm Hg or less with or without additional medical therapy, UBM appearance of the site of DS with RHAI, size of the decompression space, presence of a filtering bleb and supraciliary hypoechoic area, and scleral reflectivity around the decompression space. RESULTS: After a mean follow-up of 11.4 months +/- 4.7 (SD), the mean percentage reduction in IOP compared to preoperatively was 38% (from 26 +/- 4.5 mm Hg to 16.2 +/- 3.8 mm Hg; P =.0001). Twenty-four patients (80%) had an IOP less than 21 mm Hg; however, 7 of these eyes (23%) required additional IOP-lowering medical therapy. The operation failed in 6 patients (20%) despite additional therapy. Ultrasound biomicroscopy revealed a reduction in the size of the decompression space from 6 months postoperatively and its disappearance in 2 cases. The difference in size at the last follow-up and at 1 month postoperatively (maximum length 2.41 +/- 1.02 mm versus 3.53 +/- 0.51 mm) was significant (P =.0001). At the last examination, a filtering bleb was present in 18 patients (60%), a supraciliary hypoechoic area in 18 (60%), and hyporeflectivity of the scleral tissue around the decompression space in 14 (47%). These 3 UBM characteristics were detected singly and in various combinations. The simultaneous presence of all 3 characteristics in the same eye correlated significantly with a higher surgical success rate (P =.004). CONCLUSIONS: Ultrasound biomicroscopy showed that filtering bleb formation was frequent in eyes having DS with RHAI but that it was not the only surgically induced IOP-lowering mechanism. Increased uveoscleral and transscleral filtration may be equally important.

Maximal endothelial tissue plasminogen activator release is not impaired in patients with acute coronary syndromes before heparin treatment.

Procoagulant and fibrinolytic disturbances are described in patients with acute coronary syndromes (ACS), but whether defective maximal tissue plasminogen activator (t-PA) release from the endothelium is also present is still controversial. Previous studies did not take into consideration the contribution of heparin, which strongly affects fibrinolysis. Accordingly, in this study, we measured maximal t-PA release in patients with ACS before, during, and after heparin treatment. Maximal t-PA release was measured by the venous occlusion test in 38 hospitalized patients with confirmed ACS (18 acute myocardial infarctions and 20 unstable anginas) before starting heparin, during heparin treatment, and 4 and 12 h after discontinuation. Plasma plasminogen activator inhibitor type 1 (PAI-1), D-dimer and prothrombin fragment F1 + 2 were also measured. Eighteen age-matched subjects with no evidence of coronary disease were used as controls. At admission, patients showed significantly higher plasma levels of t-PA, PAI-1, and F1 + 2 than controls. Before heparin, maximal t-PA release was similar in patients and controls. Heparin treatment was associated with a significant increase of plasma t-PA, while it did not affect maximal t-PA release. Coagulative and fibrinolytic disturbances are present in patients with ACS, but these do not include maximal t-PA release. Among our patients, maximal t-PA release appears stable over time and is not affected by heparin treatment.

The role of disodium pamidronate in the management of bone pain due to malignancy.

A number of controlled studies have recently demonstrated the role of disodium pamidronate in the prevention of skeletal complications in patients with metastatic bone disease due to breast cancer and multiple myeloma. They have also shown that it relieves pain and is well tolerated. The aim of this open prospective study was to evaluate the acceptability of a new schedule of pamidronate infusion and to assess pain, analgesic consumption and the Karnofsky Performance Status (KPS) in patients with metastatic bone pain treated with pamidronate in association or not with chemotherapy, radiotherapy, and hormone therapy. Patients with different types of cancer and at least one painful bone metastasis were treated with two cycles of 60 mg intravenous (iv) pamidronate weekly for three consecutive doses, with a 3-week interval between the two cycles (six infusions over 7 weeks), followed by one infusion every 3 weeks for a total of 24 infusions. Two hundred patients were enrolled in the study, of whom 94 received at least the first six infusions; 25 patients received all 24 infusions. Pamidronate was well tolerated in the majority of the patients both during the first six infusions and during the whole study period. In the patients under study, pain intensity decreased compared with T0 after the first two infusions (second week of treatment). The mean equivalent daily dose of oral morphine required ranged from 21.5 to 41.5 mg/day and was low and stable during the study. For the patients who remained in the study, the KPS remained around 70 during the whole treatment period and intrasubject analysis showed a substantial stability of the KPS within each subject. A first fracture occurred within 321 days in 25% of the whole population under study. Pamidronate represents a further valid therapy to add to an already consolidated list of therapies such as radiotherapy, chemotherapy, hormone therapy and orthopaedic intervention in the pain management of patients with bone metastases. Future studies are necessary to evaluate the role of pamidronate and the appropriate schedule in patients with advanced or terminal cancer who are no longer being treated with oncological therapies.

Sulfonylurea treatment of type 2 diabetic patients does not reduce the vasodilator response to ischemia.

OBJECTIVE: Sulfonylureas block the activation of vascular potassium-dependent ATP channels and impair the vasodilating response to ischcmia in nondiabetic individuals, but it is not know whether this occurs in type 2 diabetic patients under chronic treatment with these drugs. Glimepiride, a new sulfonylurea, apparently has no cardiovascular interactions. The aim of our study was to compare the effect of the widely used compound glibenclamide, the pancreas-specific glimepiride, and diet treatment alone on brachial artery response to acute forearm ischemia. RESEARCH DESIGN AND METHODS: Brachial artery examination was performed by a high-resolution ultrasound technique on 20 type 2 diabetic patients aged mean +/- SD) 67 +/- 2 years and on 18 nondiabetic patients matched for age, hypertension, and dislipidemia. Diabetic subjects underwent three separate evaluations at the end of each 8-week treatment period, during which they received glibenclamide, glimepiride, or diet alone according to crossover design. Scans were obtained before and after 4.5 min of forearm ischemia. Postischemic vasodilation and hyperemia were expressed as percent variations in vessel diameter and blood flow. RESULTS: Postischemic vasodilation and hyperemia were, respectively, 5.42 +/- 0.90 and 331 +/- 38% during glibenclamide, 5.46 +/- 0.69 and 326 +/- 28% during glimepiride, and 5.17 +/- 0.64 and 357 +/- 35% during diet treatment (NS). These results were similar to those found in the nondiabetic patients (6.44 +/- 0.68 and 406 +/- 42%, NS). CONCLUSIONS: In type 2 diabetic patients, the vasodilating response to forearm ischemia was the same whether patients were treated with diet treatment alone or with glibenclamide or glimepiride at blood glucose-lowering equipotent closes.

N-acetyl-cysteine reduces neointimal thickening and procoagulant activity after balloon-induced injury in abdominal aortae of New Zealand white rabbits.

BACKGROUND: Procoagulant activity and oxidative stress generated by balloon injury to normal vessels promote the migration of medial smooth muscle cells and their proliferation in the intima. We hypothesised that administering levo N-acetyl-cysteine (NAC) i.v. at the time of injury, and s.c. before and after injury would reduce neointimal formation 4 weeks later and would regulate procoagulant activity in vessels with neointima undergoing ballooning a second time. METHODS AND RESULTS: at the time of injury rabbits received: NAC, unfractionated heparin (HEP) or both (NAC + HEP). Neointimal thickening at 28 days, calculated as the ratio between the intimal and medial area, was attenuated after NAC, HEP and NAC+HEP by 39%, 30% and 47% respectively when compared to untreated injured animals (CONTROLS) (p <0.05). At 28 days, bound thrombin activity and platelet adhesion 1 h after a repeated balloon injury decreased in animals receiving NAC, HEP and NAC+HEP bv 54%, 63% and 64% for thrombin activity (p <0.05 vs CONTROLS), and by 56%, 66% and 75% respectively for 111Indium-platelet deposition (p <0.05 vs CONTROLS). CONCLUSIONS: NAC in-vivo was effective in reducing neointimal thickening and procoagulant response after balloon injury.

The difficult choice of chemotherapy in patients with unresectable non-small-cell lung cancer.

The aims of this study were: to assess the attitude of non-small-cell lung cancer (NSCLC) patients to being treated with chemotherapy, determining whether and how much it differs from that expressed by patients with benign diseases or by healthy people; and to investigate how the information received about the treatment may influence the patients' decisions. A three-item self-assessment questionnaire measuring willingness to be treated with chemotherapy and presented according to three different scenarios (with an optimistic, neutral, and pessimistic physician's presentation) was administered to 104 NSCLC patients, 129 other patients with respiratory diseases (RDP), 140 health care providers (HCP) and 120 students (STU). Guttman's coefficient of reproducibility confirms the hierarchical structure of the three scenarios ranging from an optimistic to a pessimistic view. Relative to the other groups, cancer patients showed: (a) a consistently higher degree of uncertainty about whether to accept or reject chemotherapy; (b) the lowest acceptance rate in the optimistic and neutral scenario and, in contrast, the highest in the pessimistic scenario; (c) the highest percentage of constant answers, independently of the scenario presented, particularly as regards the answers "I don't know" (NSCLC = 25%, RDP = 9%, HCP = 2%, STU = 5%) and "Yes, I accept" (NSCLC = 29%, RDP = 31%, HCP = 19%, STU = 16%). Answer patterns differed markedly between cancer patients, the HCP, and the STU group, and in most cases the difference was statistically significant at a confidence level of 0.001. The differences between NSCLC and RDP patients were less marked, and not always statistically significant. The choice between accepting and rejecting chemotherapy is very difficult for patients with NSCLC, much more so than for healthy people, and it is often independent of the way the information is provided.

Total rectal resection and complete mesorectum excision followed by coloendoanal anastomosis as the optimal treatment for low rectal cancer: the experience of the National Cancer Institute of Milano.

BACKGROUND: At present, abdominoperineal resection remains the most diffuse method of treatment of very low rectal cancer. Today, we can avoid this method in some patients by using a sphincter-saving procedure. METHODS: From March 1990 to January 1999, 273 consecutive total rectal resections and coloendoanal anastomoses were performed at our Institute; this study concerns 141 consecutive patients treated for a primary adenocarcinoma of the distal rectum, from 3.5 to 8 cm from the anal verge. Patient stratification, based on definitive pathological report, was 31 Dukes' stage A (T2N0), 44 stage B (T3N0), and 66 stage C (T2N+-T3N+). RESULTS: Overall recurrence rate was 9.2%; postoperative morbidity attributable to the procedure was low. A perfect continence was documented in 61% of cases. The only pathological factor related to local recurrence rate is peritumoral lymphocytic reaction inside and around the tumor (P = .0005 and .031) independently from the number of metastatic lymph nodes, depth of fatty tissue infiltration, and lymphatic and venous neoplastic emboli. The minimum follow-up time is 12 months. CONCLUSIONS: Our data, in accordance with other authors, seem to highlight the relevant role that a well-practiced surgery, together with accurate information on the spreading of this disease, has in achieving an optimal local control of cancer.

Contrast harmonic color Doppler left ventriculography: machine-interpreted left ventricular ejection fraction compared with equilibrium-gated radionuclide ventriculography.

BACKGROUND: Multi-gated acquisition (equilibrium-gated radionuclide ventriculography) (MUGA) is considered the gold standard for measuring left ventricular ejection fraction (LVEF) because it is accurate, machine interpreted, and reproducible. Echocardiographic LVEF measurements are subject to variability in image acquisition and interpretation and to the limitations of 2-dimensional (2D) versus 3-dimensional imaging. GOAL: The shortcomings of traditional echocardiography may be addressed by combining multiplane 2D harmonic imaging, echocardiographic contrast, color Doppler ultrasonography, and digital image processing to create a new imaging modality: contrast harmonic color Doppler left ventriculography. METHODS: We compared the accuracy of a new method for measuring LVEF that allows for machine interpretation and uses contrast-enhanced intermittent harmonic color Doppler ultrasonography (CHCD). Quantitative LVEF measurements by hand-traced harmonic 2D echocardiography, contrast-enhanced harmonic 2D echocardiography, CHCD, and machine-interpreted CHCD were compared with MUGA in 35 patients. RESULTS: Contrast-enhanced intermittent harmonic color Doppler provided images with vivid endocardial definition in all patients, but hand-traced harmonic 2D echocardiography and contrast-enhanced harmonic 2D echocardiography had inadequate images in 9% of patients. The MUGA LVEF range was 0. 09 to 0.70. All echocardiographic methods showed excellent correlation with the MUGA LVEF (R (2) > 0.96), but the CHCD method had the best limits of agreement. CONCLUSIONS: Contrast-enhanced intermittent harmonic color Doppler LVEF correlates with MUGA at least as well as traditional noncontrasted echocardiography, but it provides diagnostic images in a greater proportion of patients. The CHCD images have vivid endocardial delineation and can be machine interpreted.

Assessment of hospitalised cancer patients' needs by the Needs Evaluation Questionnaire.

BACKGROUND: Cancer disease modifies the order and the nature of needs connected with the state of health. The aim of this study was to evaluate the informative, psychological, social and practical needs of hospitalised cancer patients by means of the Needs Evaluation Questionnaire (NEQ), an instrument designed concisely for the convenience of patients and medical staff. PATIENTS AND METHODS: Different samples of consecutive hospitalised cancer patients were involved in the various phases of designing the instrument: 30 patients for items identification, 101 patients for completeness and acceptability evaluation, 423 patients for construct validity and prevalence of needs; content and reliability analysis were performed on 2 subsamples of, respectively, 60 and 88 of the patients from the last sample. RESULTS: The validation analysis showed rather good reliability, structure validity and internal consistency of the questionnaire. The prevalence analysis showed that the most common needs were: 'more information about my future conditions' (74%); 'more information about my diagnosis' (56%); 'more information about the exams I am undergoing' (52%); 'more explanations on treatments' (51%); 'to have a better dialogue with clinicians' (57%); 'better services from the hospital' (bathrooms, meals, cleaning) (56%). CONCLUSIONS: The NEQ, self-completed by patients, has proven to be a useful clinical tool for obtaining a systematic and undistorted overview of the principal needs with respect to the state of health of patients. This instrument, which can also be administered by persons not belonging to the health care system such as volunteers, and inserted into the patients' hospital charts, could be used by the medical staff to identify the real needs of patients at an early stage.

Evaluation of growth hormone administration in patients with chronic heart failure secondary to coronary artery disease.

We have examined the effects of 6 months of treatment with growth hormone (GH) (0.02 U/kg/day) in 10 patients with chronic postischemic cardiac failure. Ten patients matched for age, body mass index, functional class, and ejection fraction served as a control group. In the GH group, 1 patient died and 2 were withdrawn from the study because of arrhythmia or worsening of heart failure. In the control group, 1 patient died and 1 patient was withdrawn from the study because of progressive heart failure. Among GH patients, those with an unfavorable outcome had a greater left ventricular end-diastolic diameter (79, 82, and 88 mm) on entry to the study than patients without adverse events (range 62 to 72 mm). At the end of the study, the seven GH patients reported a feeling of well-being and had a significant increase in their exercise test duration (462 +/- 121 vs 591 +/- 105 seconds, p <0.05). Low baseline insulin-like growth factor-I values were increased with GH treatment (189 +/- 52 vs 100 +/- 22 ng/ml, p <0.01). GH did not change left ventricular diameters or wall thickness. A trend toward decreased serum triglyceride levels and adipose body tissue associated with an increase in high-density lipoproteins was observed in the GH group. In conclusion, our present data support previous suggestions that GH treatment exerts some beneficial effects in patients with chronic, stabilized, moderately severe heart failure, but may have deleterious effects in patients with more severe heart failure.
