The authors reported a case of a 56-year-old man with lung cancer which secreted human growth hormone (hGH). On admission, he had clubbed fingers and gonalgia without complaining cough or sputum. Serological examination revealed a high level of hGH which was 22.7 ng/ml (normal < 1.46). Right upper lobectomy was performed in February, 1994. It returned to the normal level after resection of the tumor. Gonalgia was improved but he still had clubbed fingers after operation. Histological examination of the tumor shows poorly differentiated adenocarcinoma with no evidence of lymph node metastasis. Immunohistochemical study showed that a group of the tumor cells demonstrated a specific reaction for anti-hGH antibody.

The patient was a 61-year-old man admitted with the complaints of cough, arthralgia, and swelling of the legs. A chest roentgenogram and chest computed tomographic scan revealed a giant mass in the right upper lobe. Transperitoneal lung biopsy was performed, and a diagnosis of poorly differentiated adenocarcinoma was made. Physical examination confirmed swelling of the legs and clubbing of fingers on both hands. Bone scintigrams showed marked accumulation of 99 m-Tc-MDP in the long bones, bones of the hands, and patellae. These findings yielded a diagnosis of pulmonary hypertrophic osteoarthropathy associated with primary lung cancer. Although a high serum level of growth hormone was also detected, immunohistochemical analysis did not find growth hormone in the tumor itself. Chemotherapy and radiotherapy were performed but did not stop progression of the disease. The patient subsequently experienced worsening arthralgia and swelling of the legs. Steroid therapy rapidly alleviated the arthralgia and swelling, but not the clubbing of the fingers. Thereafter, the patient's serum CRP and ICTP dropped to normal levels, and the abnormal findings of bone scintigrams subsequently disappeared. The pulmonary hypertrophic osteoarthropathy was not clearly attributable to growth hormone. Steroid therapy was effective in this case. Bone scintigrams and serum CRP and ICTP may be useful indicators in the therapeutic follow-up and monitoring of patients with pulmonary hypertrophic osteoarthropathy.

Cardiovascular disease is the major cause of morbidity and mortality in Westernised societies. It is well known that the aetiology of this devastating disorder involves both genetic and environmental factors. Sequence variants of the components of the renin-angiotensin-aldosterone system and the kallikrein-kinin system are suggested to have significant influences on cardiovascular homeostasis. Both gene targeting and transgenic studies in mice have clearly suggested a critical role of the angiotensin converting enzyme (ACE) gene in blood pressure regulation. Furthermore, an up-regulation of myocardial ACE gene expression has been observed in patients with heart failure. Thus, the ACE gene has been recognised as a top candidate gene for cardiovascular research. Over the past decade, the insertion/deletion (I/D) polymorphism of a 287-bp Alu element in intron 16 of the ACE gene has attracted significant attention and has been extensively investigated in a spectrum of cardiovascular phenotypes, because of its correlation with serum ACE activity. A large majority of previous studies have shown a positive association between the DD genotype and an increased risk of myocardial infarction, but results in hypertension, left ventricular hypertrophy, cardiomyopathy and restenosis after percutaneous transluminal coronary angioplasty remain quite controversial. Since ACE inhibitors are widely used in hypertension and congestive heart failure, we also review the literature on the relationship of ACE I/D polymorphism with ACE inhibitor response. It appears that this polymorphism has some moderate impact on the cardiovascular response to ACE inhibitors but there is no consensus as to which allele confers a more pronounced effect. In addition, previous data are suggestive of an association between the ACE I allele and a greater risk of increased occurrence of ACE inhibitor-induced cough, but such a relationship needs further confirmation. Overall, since ACE I/D is only an intronic marker, the true locus that controls the ACE enzyme activity remains to be identified, and could be located within either the ACE gene or another nearby gene such as the human growth hormone gene. We note that since associations tend to vary across different gender or ethnic groups, or across different socio-ecological settings, consideration of potential gene-gene and gene-environment interactions should be made. Furthermore, the dissection of the genetic underpinning of cardiovascular disease needs delineation of all molecular variants of the key physiological pathways that influence cardiovascular function.

Pulmonary carcinoid tumors are neuroendocrine malignant tumors that make up 1% to 2% of all lung tumors. According to histopathologic criteria, carcinoids can be divided into typical (TC) and atypical (AC) carcinoids. Carcinoids can be placed in a spectrum of neuroendocrine tumors, ranging from low-grade malignant TC to intermediate AC to high-grade large-cell neuroendocrine carcinoma and small-cell lung carcinoma. Familial pulmonary carcinoids are rare. The most common symptoms are hemoptysis, cough, recurrent pulmonary infection, fever, chest discomfort and chest pain, unilateral wheezing, and shortness of breath. Paraneoplastic syndromes are rare and include carcinoid syndrome, Cushing's syndrome, and ectopic growth hormone-releasing hormone secretion. The diagnosis is usually established by flexible bronchoscopy and biopsy, although occasionally this can result in severe hemorrhage. Immunoscintigraphy by somatostatin analogs can also be useful in diagnosis. The treatment of choice is surgical resection, and prognosis is relatively good in TC, although it is worse in AC. The role of radiotherapy and chemotherapy as part of multimodality treatment or palliation is still debated.

Idiopathic diffuse hyperplasia of pulmonary neuroendocrine cells (IDHPNC) is a rare disorder that most often presents clinically as obliterative bronchiolitis, but has also been associated with ectopic corticotropin syndrome. We describe a 49-year-old lifetime non-smoking female with longstanding cough, progressive exertional dyspnoea, and fixed airflow limitation, who presented with acromegaly. Head magnetic resonance imaging revealed a pituitary microadenoma and open lung biopsy revealed a multifocal proliferation of neuroendocrine cells which were immunopositive for both corticotropin and growth hormone-releasing hormone. To our knowledge, this is the first report of acromegaly associated with IDHPNC, and supports the possibility that IDHPNC may fall at one extreme of the spectrum of disorders encountered in multiple endocrine neoplasia type 1.

Hypertrophic osteoarthropathy is an important manifestation of lung carcinoma, particularly in a non-small cell tumor, and hampers quality of life. Although removal of the primary tumor usually resolves this syndrome, effective treatment in patients with advanced lung carcinoma has not been established. Recently, an orally active, selective epidermal growth factor receptor tyrosine kinase (EGFR) inhibitor ("Gefitinib") provided clinical anti-tumor activity. We describe a 71-year-old male smoker with cough, who presented with clubbed fingers. A transbronchial lung biopsy (stage T2N3M1-IV) on a cavity lesion in the left lower lobe showed the features of adenocarcinoma, while bone scintigram revealed bilaterally symmetrical abnormal uptakes in the lower extremities, suggesting secondary hypertrophic osteoarthropathy. The serum level of growth hormone was increased to 1.42 ng/ml. Chemotherapy (cisplatin, vinorelbine) was not effective. Gefitinib, as a second-line therapy, induced disappearance of the abnormal accumulation on bone scintigraphy and decrease of the cavity in the lung and of serum growth hormone. The presented case suggests that the EGFR inhibitor might be a promising option for the treatment of hypertrophic osteoarthropathy with advanced lung adenocarcinoma.

Systemic therapeutic protein delivery through the lungs could potentially replace delivery by injection, but safety needs to be established in patients with known pulmonary disease. This study determined the short-term safety profile of recombinant human growth hormone (rhGH; somatropin) inhalation therapy in clinically stable adult subjects with mild to moderate asthma and methacholine sensitivity. This randomized, placebo-controlled study had two phases: (1) an escalating 3-dose, 4-day/dosage tolerance phase; and (2) a 14-day, crossover design comparability phase. Noninferiority in maintaining forced expiratory volume in 1 second (FEV(1)) was tested for somatropin inhalation powder (SIP) compared with subcutaneously injected rhGH (Hsc) and inhaled placebo. Lung hyperresponsiveness was assessed by methacholine bronchoprovocative challenge, and adverse events (AEs) were recorded. Eight and 18 subjects enrolled in the first and second phases, respectively. Noninferiority of SIP compared with Hsc and placebo was established for FEV(1) after the first and last doses, and noninferiority of SIP compared with Hsc for methacholine challenge was established after the first dose. Pulmonary uptake and systemic distribution of SIP was confirmed by increased serum insulin-like growth factor I levels. Mild, nonprogressive cough and nasal congestion occurred more commonly with SIP. All other treatment-emergent AEs were mild, similar across active treatment groups, and consistent with rhGH treatment. In clinically stable adults with mild to moderate asthma, no significant changes in pulmonary function or worsening of asthma complaints occurred during SIP treatment. Future studies of SIP may enroll subjects with mild to moderate asthma for longer-term evaluation of safety and efficacy.

Persons with spinal cord injury (SCI) have secondary medical consequences of paralysis and/or the consequences of extreme inactivity. The metabolic changes that result from reduced activity include insulin resistance with carbohydrate disorders and dyslipidemia. A higher prevalence of coronary artery calcification was found in persons with SCI than that in matched able-bodied controls. A depression in anabolic hormones, circulating testosterone and growth hormone, has been described. Adverse soft tissue body composition changes of increased adiposity and reduced skeletal muscle are appreciated. Immobilization is the cause for sublesional disuse osteoporosis with an associated increased risk of fragility fracture. Bowel dysmotility affects all segments of the gastrointestinal tract, with an interest in better defining and addressing gastroesophageal reflux disease and difficulty with evacuation. Developing and testing more effective approaches to cleanse the bowel for elective colonoscopy are being evaluated. The extent of respiratory dysfunction depends on the level and completeness of SCI. Individuals with higher spinal lesions have both restrictive and obstructive airway disease. Pharmacological approaches and expiratory muscle training are being studied as interventions to improve pulmonary function and cough strength with the objective of reducing pulmonary complications. Persons with spinal lesions above the 6th thoracic level lack both cardiac and peripheral vascular mechanisms to maintain blood pressure, and they are frequently hypotensive, with even worse hypotension with upright posture. Persistent and/or orthostatic hypotension may predispose those with SCI to cognitive impairments. The safety and efficacy of anti-hypotensive agents to normalize blood pressure in persons with higher level cord lesions is being investigated.

Frequent infections contribute to childhood stunting in developing countries but the causal pathways are uncertain. We tested the hypothesis that intercurrent illnesses suppress the growth hormone axis through reductions in insulin-like growth factor 1 (IGF-1). In a birth cohort of 202 HIV-unexposed Zimbabwean infants, we analyzed data on 7-day illness recall and measured plasma interleukin-6, C-reactive protein, alpha-1-acid glycoprotein, and IGF-1 by enzyme-linked immunosorbent assay, at age 6 weeks, and then 3, 6, 12, and 18 months. Children with recent acute illness had lower IGF-1 concentrations than healthy children and IGF-1 correlated inversely (P < 0.05) with inflammatory biomarkers at most time points between 3 and 18 months. Using path analysis, we showed that cough and fever had a predominantly indirect effect on suppressing IGF-1, through the acute-phase response, whereas diarrhea had a predominantly direct effect on IGF-1. Acute illness may therefore impact the growth hormone axis through both direct and indirect pathways.

A 27-year-old male patient presented with cough and right-sided, light thoracic pain. His physical appearance showed typical features of gigantism. Subsequently, further diagnostic work-up showed elevated level of growth hormone and a huge tumor of the right lung, identifying a typical pulmonary carcinoid tumor (TPCT). Curative surgery was performed leading to normalization of the elevated growth hormone levels few days after surgery. Two- and five-year follow-up showed no signs of recurrence. Respected to tumor size, we determined the largest TPCT to be reported in medical literature history.
