Short-term pre-surgical treatment with somatostatin analogues, octreotide and lanreotide, in acromegaly

Eighteen patients with symptoms of active acromegaly were treated with somatostatin analogues for 4 weeks before surgery. Both before and after the treatment, levels of growth hormone (GH), prolactin (PRL), insulin growth factor -I (IGF-I), luteotropin (LH), folliculostimulin (FSH) and subunit α of glycoprotein hormones were estimated. Glucose tolerance test, magnetic resonance imaging (MRI) examination, sight acuity and field of vision tests were also performed. The same tests were performed on ten control patients with clinically and biochemically active acromegaly, subjected to surgery but not treated with somatostatin analogues. In six patients treated with somatostatin analogues GH levels decreased significantly to less than 5 ng/ml and in two patients remained elevated while in 10 patients GH level decreased and ranged from 6.1 to 42.9 ng/ml. In 13 patients we observed a decrease in IGF-I to normal levels (<400 ng/dl) and in 3 patients we noted a decrease to levels slightly higher than normal. There was also a slight decrease in α subunit concentration. In the glucose inhibition test 4 patients demonstrated normalized GH levels. In patients with elevated PRL and TSH levels, treatment with somatostatin analogues induced their decrease. No changes were observed in levels of LH and FSH. After therapy MRI examination disclosed a decrease in tumor volume in two patients (by 20 and 25%, respectively) and no changes in tumor size in 16 patients. The two patients with a decreased tumor volume also showed normalized glucose tolerance tests. All patients manifested an improved clinical condition. Neurosurgeons disclosed a decreased tumor consistency which greatly facilitated surgical procedure. Our studies documented favourable effects of somatostatin analogues on the assayed hormone levels, and on the general condition of the patients as well as on the course of the surgical procedure itself.

Acromegaly--a novel view of the patient. Polish proposals for diagnostic and therapeutic procedures in the light of recent reports.

is usually delayed and is often associated with the development of various complications causing premature mortality. In patients with hypertension, heart failure, diabetes, and arthropathy that is non-specific for age, attention should be paid to the occurrence of somatic signs of acromegaly. As a screening test, insulin-like growth factor-1 (IGF-1) concentration should be assessed. Further diagnostic and treatment procedures are possible in specialised centres. The first-line therapy is selective transsphenoidal adenomectomy. Patients with a good prognosis related to a surgical removal of the pituitary tumour should be referred only to centres experienced in performing this type of procedure, after pharmacological preparation. Other patients, and those who have not recovered after surgical treatment, should be subjected to long-term pharmacotherapy with long-acting somatostatin analogues. In each case, the complications of acromegaly should be followed-up long-term and actively treated. This proposed new recommendation should be helpful for the management of patients with acromegaly.

Delayed diagnosis of primary hyperparathyroidism in a patient with osteoclastoma.

Primary hyperparathyroidism (HPTo) nowadays is most often recognized incidentally in the asymptomatic period as a result of biochemical screening or evaluation of low bone mass. Classical manifestations of the disease are present in about 15-20% of patients. We present the case of a 28-year-old male patient who had been treated for two years for osteoclastoma of the proximal tibia, first by intralesional curettage with cement filling followed by bone grafting, and finally with a reconstructive arthroplasty of the knee joint. The patient had been consulted in different medical centers by at least 14 doctors representing 9 different specialties, but the correct diagnosis of HPTo had not been made, although classic manifestations of the disease had been present for 5-6 years. This suggests that a diagnosis of HPTo is difficult nowadays. Therefore, determination of serum calcium concentration and other markers of calcium and phosphate metabolism should be obligatory in patients with bone lesions.

Assessment of real-world usage of lanreotide AUTOGEL 120 in Polish acromegalic patients – results from the prospective 12-month phase of Lanro-Study

Aim of the study To assess resource utilization and costs of treatment with lanreotide AUTOGEL 120 mg (ATG120) administered as part of routine acromegaly care in Poland. Material and methods A multicentre, non-interventional, observational study on resource utilization in Polish acromegalic patients treated with ATG120 at 4 weeks or extended (> 4 weeks) dosing interval. The study recruited adult acromegalic patients treated medically for ≥ 1 year including at least 3 injections of ATG120. Data on dosing interval, aspects of administration, and resource utilization were collected prospectively during 12 months. Costs were calculated in PLN from the public health-care payer perspective for the year 2013. Results 139 patients were included in the analysis. Changes in dosing regimen were reported in 14 (9.4%) patients. Combined treatment was used in 11 (8%) patients. Seventy patients (50%) received ATG120 at an extended dosing interval; the mean number of days between injections was 35.56 (SD 8.4). ATG120 was predominantly administered in an out-patient setting (77%), by health-care professionals (94%). Mean time needed for preparation and administration was 4.33 and 1.58 min, respectively, mean product wastage – 0.13 mg. Patients were predominantly treated in an out-patient setting with 7.06 physician visits/patient/year. The most common control examinations were magnetic resonance imaging of brain and brain stem (1.36/patient/year), ultrasound of the neck (1.35/patient/year), GH (1.69/patient/year), glycaemia (1.12/patient/year), IGF-1 (0.84/patient/year), pituitary-thyroid axis hormone levels assessment (TSH-0.58/patient/year, T4-0.78/patient/year). There were 0.43 hospitalizations/patient/year. For direct medical costs estimated at PLN 50 692/patient/year the main item was the costs of ATG120 (PLN 4103.87/patient/month; 97%). The mean medical cost, excluding pharmacotherapy, was PLN 1445/patient/year (out-patient care – 49%, hospitalization – 23%, diagnostics/laboratory tests – 28%). Conclusions These results represent the current use of ATG120 in the population of Polish acromegalic patients in a realistic clinical setting. Findings that 50% of patients could be treated with dose intervals of longer than 28 days support the potential of ATG120 to reduce the treatment burden.

Endoskopowe odbarczenie oczodołów w przebiegu wytrzeszczu złośliwego w chorobie Graves-Basedowa ☆ ☆☆

Summary Thyroidorbithopaty is inflammatory disease against the autoimmune reaction. Clinical symptoms are connected withincreasing the volume of retrobulbar tissues. As a result of the autoimmune reaction is reaching to the blow-up, thickening extrabulbar muscles, of appearance of the swelling of the inflammable body of the fat body and tear glands. Heightened retrobulbar pressure is leading to the exophthalmos of the eyeball. He can be a consequence of the exophthalmos insuffiency of eyelids, drying, ulcerations of the cornea. In external eyball muscles changes are leading to eyeball mobility limitation, the double vision, whereas the pressure on the optic nerve can be a reason of injuring it what next serious complications constitute thyroidorbitopathy. In the case active orbithopaty an immunosuppression is an essential way of curing. Disabled advanced form thyroidorbithopaty is a reading for curing applying treatment methods. Outside clinical symptoms among others findings of CT, MR examinations are deciding using it. A treatment is one of methods of operating intranasal curing, of endoscopic decompression of the orbital cavity. Authors are showing the method of operating curing on the basis of the case ill around thyroid orbithopathy in the course of illness Graves- of Basedow with accompanying diabetes.

Anti-thyroidal peroxidase antibodies are associated with thyrotropin levels in hypothyroid patients and in euthyroid individuals

OBJECTIVE The study was designed to evaluate the relationship between thyroid antibodies and gland dysfunction, with the aim of finding a clinically useful threshold value of thyreoperoxidase antibodies, which could prove to be predictive for thyroid failure. MATERIAL AND METHODS The study was conducted on 99 women, ages ranging from 18-91 years (mean age: 45.5 ±17.0), were treated as outpatients in the Department of Endocrinology, Metabolism and Internal Medicine. Analysis of serum samples for TSH concentration and anti-TPO titers was conducted. RESULTS The most common disorder was hypothyroidism. Anti-TPO titers above reference range values were observed in 35 patients (35.4%): 21 (60%) were hypothyroid and 11 (31.4 %) were euthyroid. The anti-TPO and TSH serum levels correlated both in patients with high thyroid antibody titers, and in the anti-TPO negative groups. To find the threshold value of anti- TPO that would help predict hypothyroidism, receiver operating curves were used. With this approach, TPO antibody titers over 17 IU/ml indicated hypothyroidism with a 90% sensitivity and 75% sensibility. CONCLUSIONS It can be postulated that the cutoff values of anti-TPO in the general population should be decreased in order to improve autoimmune thyroid disorder screening. Obviously, using that margin may lead initially to the detection of some false positive subjects. However, with lower cut-off values, more patients can be enrolled into thyroid follow-up groups. In this way, many people could avoid complications of undiagnosed, insidious thyroid failure.

The efficacy of octreotide LAR (long acting release) treatment in patients with somatotropinoma, and mixed pituitary tumours

Objective: The efficacy of somatostatin analogues in the treatment of acromegaly is not always equal and therefore we wanted to evaluate the efficacy of therapy with octreotide long acting release (LAR) in patients with monohormonal tumours (somatotropinomas) in comparison to individuals with mixed pituitary tumours secreting alphasubunit.Method: The 35 acromegalic patients (18 males and 17 females), aged 41.8 ± 8.8 years, were divided into 2 groups according to the secreted hormones: 1 with mixed pituitary tumours with elevated growth hormone and alpha-subunit concentrations, the other with isolated growth hormone hypersecretion and normal alpha-subunit levels. The groups included 19 patients (9 males and 10 females), aged 40.1 ± 7.1 years (mean ± SD), and 16 patients (9 males and 7 females) aged 43.8 ± 8.8 years (mean ± SD), respectively.Results: The decrease of GH and IGF-I levels after octreotide LAR treatment were observed in both groups. However, the reduction of GH and IGF-I concentrations was not equal in both groups and the differences between both groups were statistically significant (P=0.01 for GH levels, and P=0.047 for IGF-I levels).Conclusions: After octreotide LAR treatment, the decrease of GH level and of mean IGF-I values was greater in patients with mixed pituitary tumours and high alpha-subunit concentrations than in patients with isolated GH hypersecretion and normal alpha-subunit levels.
