    Assessment of Adrenocortical Dysfunction in Patients with Stable Liver Cirrhosis

    Acta Endo (Buc) 2016 12(3): 262-267 doi: 10.4183/aeb.2016.262

    Abstract
    Introduction. Relative adrenal insufficiency (RAI) is common in the setting of critical illness as well as in hemodynamically instable cirrhotic patients with sepsis. Several studies have also shown that RAI is frequent in patients with stable cirrhosis without sepsis. The aim of this study was to prospectively assess the incidence of RAI in patients with stable cirrhosis. Patients and Methods. Forty-seven patients with hemodynamically stable liver cirrhosis without sepsis were prospectively included. RAI, assessed by using low doseshort Synacthen test (LD-SST), was defined as either a basal total cortisol concentration below 3.6 μg/dL or a peak total serum cortisol ≤ 16 μg/dL at 30 min after stimulation. Results. RAI was present in 10 (21.3%) of 47 cirrhotic patients. Peak cortisol level was negatively correlated with the severity of cirrhosis evaluated by Child- Turcotte-Pugh (CTP) (r=-0.46; P=0.001) and Model for End- Stage Liver Disease (MELD) (r=-0.51; P=0.001) scores. The frequency of RAI increased from CTP-A (10%) to CTP-B (30%) to CTP-C (60%). Conclusion. RAI diagnosed by LD-SST is frequent in patients with stable cirrhosis and is related to the severity of liver disease. Further studies are needed to define clinical importance of RAI in stable cirrhotic patients.

    Persistence of neurological cretinism in old endemic goiter areas of the Carphatians

    Acta Endo (Buc) 2005 1(3): 311-324 doi: 10.4183/aeb.2005.311

    Abstract
    The subCarpathian areas of Arges county are now characterized by a moderate endemia of iodine deficiency disorders (IDD) due to salt iodization. However, we found some cases of endemic cretinism (EC), that is the major expression of anomalies in the physical and intellectual development caused by a severe iodine deficiency. There are presented 5 patients, 4 men and 1 woman, with neurological endemic cretinism (NEC) (n=2) and mixed forms of the disease (n=3), coming from 2 old endemic areas (medium urinary iodine excretion in the studied patients 20.8 g/day), diagnosed and treated in outpatients clinics or in hospitals. Four patients are members of the same family. The age of the patients is between 36 and 84 years old, the average age being 69. The intellectual capacity was assessed by using the Wechsler and Raven tests, the average intelligence quotient (IQ) value was of 20.8 points ? 1.47. The thyroid volumes (TV) were estimated by palpatory method and by ultrasonography and were between 8.7-200 ml. TSH values in studied patients ranged between 3.8-26 IU/ml and free T4 ranged between 0.272-1.22 ng/dl. Aggregation of more cases of endemic cretinism in the same family suggests the occurrence of some genetic factors. In conclusion, the old age (over 70 years old) of 4 cretins shows they are remnants of the old IDD endemia. However, there is also an isolated case of middle age (36 years old) suggesting an inadequate iodine intake, despite a law regarding salt iodization which has been operating since 1962. More attention to the universal salt iodization and to consumption of iodized salt in the rural areas is necessary.

    Type Ib pseudohypoparathyroidism associated with thrombocytopenia and possibly resistance to TSH

    Acta Endo (Buc) 2008 4(3): 321-335 doi: 10.4183/aeb.2008.321

    Abstract
    An 18 years old, tall man presented for circumoral numbness, paresthesias, and hypocalcaemia, without carpopedal spasm or seizures. Previous medical history revealed bilateral cataract and osseous cysts on limbs at the age of 12. Hypocalcaemia resistant to calcium treatment and mild increased TSH levels were present. At diagnosis, we noticed a normal phenotype with tall stature, moderate hypocalcaemia (5.8 mg/dL), hyperphosphatemia (5.08 mg/dL) and significantly higher than normal intact parathormone (PTH) levels (518 pg/mL), in the presence of normal serum levels of 25-hydroxy vitamin D (53.56 ng/mL). The mother and the family members have been found in good health. All these data strongly suggested sporadic pseudohypoparathyroidism type Ib (PHP-Ib), but with some features of PHP - type Ia, like the osseous cysts. We were not able to perform molecular genetic tests. The nearly complete recovery of clinical and biochemical signs (normalization of PTH, calcaemia, phosphatemia, and a normal DXA osteodensitometry) after 2 years of chronic treatment with activated 1,25- dihydroxycholecalciferol (2.00-0.75 μg/day) indirectly, but strongly confirmed the diagnosis of pseudohypoparathyroidism. The patient may have resistance to TSH evidenced by high TSH\r\n(range 4.8-7.5 mIU/L), with normal thyroid hormone levels, absence of goiter and normal TPO antibodies. The TRH test (400 μg i.v.) showed a response of TSH, and also of serum thyroxine and triiodothyronine in a range that did not clarify the diagnosis. This association of the resistance to TSH with type Ib PHP was relatively recently reported by two groups (17,20) and before them it was reported only in PHP-Ia. Our patient also showed mild thrombocytopenia, with normal bleeding time, indicating also a possible Gsα deficiency in platelets. In conclusion, our patient with sporadic pseudohypoparathyroidism without clinical phenotype of Albright hereditary osteodystrophy is highly suggestive for the type Ib PHP. A possible resistance to TSH and thrombocytopenia associated are features related to the genetic mechanisms found also in type Ia PHP. It is tempting to suggest that this case is one of the new variants of pseudohypoparathyroidism-Ib, recently reported.

    Clinical Prognostic Factors in pre-and Post-Menopausal Women with Ovarian Carcinoma

    Acta Endo (Buc) 2018 14(3): 353-359 doi: 10.4183/aeb.2018.353

    Abstract
    Aims. To assess the impact of prognostic factors on the outcome of ovarian carcinoma (OC) and to determine the difference between pre and postmenopausal patients. Design. Retrospective cohort, single centre study Subjects and Methods. One-hundred-sixty patients with stage IC-IV OC diagnosed between 2004-2016 were included. Treatment consisted in primary surgery followed by adjuvant chemotherapy (n=127, 79.4%), neoadjuvant chemotherapy followed by surgery (n=27, 16.9%) and chemotherapy alone (3.7%). Results. At diagnosis 62 patients (38.8%) were premenopausal. Most patients presented with advanced OC (stage III/IV, 63.1%). After a median follow-up of 60 months, median progression free survival (PFS) for all stages was 36 months and median overall survival (OS) was 96 months. Postmenopausal patients had a poorer oncologic outcome compared with pre-menopausal women (PFS 24 vs. 72 months, p=0.0001, HR=2.32). Other clinical prognostic factors identified were performance status 1 vs. 0 (p=0.0001), ascites (p=0.027). Pathology prognostic factors were tumour grade (G1 vs. G2 and G3, p=0.0001) and endometrioid subtype compared to serous (p=0.008). Patients with residual disease after surgery had an increased risk of recurrence and death (HR=6.1, p=0.0001 and HR=4.2, p=0.0001). Conclusion. Premenopausal patients had a better oncologic long-term outcome and stage, ascites, grading, residual disease, were independent prognostic factors.

    Age-related endocrine tumors: non-functioning adrenal tumors as compared to pituitary adenomas

    Acta Endo (Buc) 2009 5(3): 371-384 doi: 10.4183/aeb.2009.371

    Abstract
    Background. Advances in imaging techniques have led to increasing discovery of\r\nadrenal and pituitary &#8220;incidentalomas&#8221;, tumors with normal endocrine function and no\r\ncompression mass effects. We evaluated the age at diagnosis (AD) in patients with benign\r\nnon-functioning adrenal incidentalomas, as compared to pituitary non-functioning tumors,\r\nin a series of patients from a national center of endocrinology. Methods. From 2,123\r\nconsecutive patients with adrenal and pituitary tumors hospitalized between 1977 - 2009,\r\n2,069 patients were analysed. The study groups included: group A - 137 patients with\r\nadrenal incidentalomas (AI), group B - 534 patients with pituitary incidentalomas (PI).\r\nControl groups included 1,398 patients: group C1 147 patients with adrenal carcinomas or\r\nbenign hormone-secreting adrenal tumors, and group C2, 1,251 patients with pituitary\r\nsecreting adenomas or large non-functioning pituitary macroadenomas (NFA). Imaging was\r\ndone by computed tomography and/or magnetic resonance after 1981 and by skull X-ray or\r\npneumoencephalography before 1981. Results. Mean age AD is more advanced in patients\r\nwith AI (53 ? 11.9 years, range 21 - 78 yr) than in patients with PI (36.8 ? 13.1 years, range\r\n10 - 81 yr), p < 0.01. AD was higher in AI than in patients with secreting adrenal tumors,\r\nbut similar in patients with adrenal malignancy. There is an age-related increase in the\r\nproportion of AI among patients with adrenal tumors, and of NFA, but not of PI, among\r\npatients with pituitary tumors. In patients aged over 65 years, 74% of patients with adrenal\r\ntumors have AI, while only 18% of patients with pituitary tumors have PI and 42% have\r\nNFA. AD in NFA (49.3 ? 13.1 yr, range 12 - 79 yr) was more advanced than in PI (p < 0.01).\r\nAD does not correlate with tumor size. Tumor growth occurred in 24% of AI (follow-up 3.0\r\n? 2.8 yr) and only in 0.7% of PI, p<0.01 (follow-up 3.1 ? 2.5 yr).\r\nConclusions. Adrenal non-functioning benign tumors show a clear association with ageing,\r\nin contrast with pituitary incidentalomas. It seems unlikely that most pituitary incidentalomas in\r\nyoung patients become large NFA, whose development seems to be also age-related. It is tempting\r\nto suggest that pituitary tumorigenesis starts earlier than adrenal tumorigenesis.

    Thyroid hormones and proinflamatory cytokines' profile in amiodarone-induced thyrotoxicosis

    Acta Endo (Buc) 2007 3(4): 417-436 doi: 10.4183/aeb.2007.417

    Abstract
    In this study we aimed to assess amiodarone&#8217;s effects on thyroid hormones, C reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor (TNF-&#945;) profile in amiodarone-induced thyrotoxicosis (AIT) and their relationship with arrhythmias. In 60 patients with AIT (29M/31F), aged 59.7 ? 1.5 years and 105 hyperthyroid patients (25M/80F), aged 59.4 ? 1 years, TSH, total T3, total T4, free T4 were measured by IRMA or microenzymatic immunoassay. In 11 AIT patients and 26 patients with common hyperthyroidism, without significant Graves&#8217; ophthalmopathy, CRP, IL-6 and TNF-&#945; were measured by chemiluminescent immunoassays. AIT patients showed significantly lower T3 levels (273.82 ? 18.76 ng/dL) as compared to common thyrotoxicosis (361.89 ? 13.47 ng/dL), p<0.001, while T4 and FT4 were similar. AIT patients showed similar CRP, IL-6 and TNF-&#945; levels to common hyperthyroidism (10.22 ? 3.03 mg/L vs. 6.31 ? 2.33 mg/L, p=0.11, for CRP, 17.46 ? 13.09 pg/mL vs. 6.46 ? 1.14 pg/mL, p=0.65, for IL-6, and 9.9 ? 1.76 pg/mL vs. 12.85 ? 2.22 pg/mL, p=0.22, for TNF-&#945;, respectively. Patients with arrhythmias (n=19) showed significantly higher CRP, IL-6 and TNF-&#945; levels as compared to patients without arrhythmias (n= 18): 10.81 ? 3.35 mg/L vs. 3.96 ? 1.08 mg/L, p=0.05, for CRP, 15.15 ? 7.52 pg/mL vs. 4.02 ? 0.74 pg/mL, p=0.007 for IL-6, and 15.16 ? 3.33 pg/mL vs. 9.2 ? 0.82 pg/mL, p=0.037 for TNF-&#945;. In conclusion, AIT showed a similar pattern of proinflammatory cytokines to common hyperthyroidism. Increased CRP, IL-6 and TNF-&#945; are found only in patients with thyrotoxicosis associated with atrial fibrillation or other arrhythmias.

    The outcome of macroprolactinomas resistant to dopamine agonists

    Acta Endo (Buc) 2005 1(4): 423-440 doi: 10.4183/aeb.2005.423

    Abstract
    Aim: We aimed to assess the final outcome of combined therapeutic approaches in patients with macroprolactinomas that were resistant to dopamine agonists (DA).\r\nPatients: Records of patients with macroprolactinoma hospitalized in the Institute of Endocrinology, Bucharest, between 1978-2005, were reviewed. There were 29 eligible patients resistant to DA therapy (8 men and 21 women), out of 119 patients with macroprolactinomas (24.4%); age at diagnosis of the resistant patients ranged between 16-59 years (31.9 ? 2.4 years), with mean prolactin (PRL) levels 2,110.2 ? 656.6 ng/mL (range 42-16,000 ng/mL). The mean maximal tumor diameter was 2.7 ? 0.2 cm (range 1-6.8 cm).\r\nMethods: Rapid fluoroimmunoassay using Europium was used for hormonal levels; computed tomography imaging and/or MRI were used to assess tumor size. Study design: The resistance to DA drugs was evaluated using initial criteria: the lack of prolactinoma response to current daily dose of Bromocriptine (BRC) 7.5 mg/day or to Cabergoline (CAB) up to 2 mg/week for at least 6 months (step 1) or final criteria: the lack of response to high BRC doses (30 mg/day) or CAB doses between 2.5-4 mg/week for at least 6 months (step 2). The lack of response was considered if PRL levels remained above the upper normal limit (20 ng/mL) and the tumor mass size decreased by less than 50%. All resistant cases at step 1 received thereafter maximal medical therapy with DA drugs, according to step 2. Thereafter, resistant macroprolactinomas after step 2 were submitted to step 3 - high voltage radiotherapy ? surgery. Serum PRL levels and tumor size were finally evaluated 110 ? 26.5 months later (range: 6-381).\r\nResults: Outcome of medical therapy with DA (n=29): Overall, 7 out of 29 resistant macroprolactinomas (24.1%) were successfully treated by increasing BRC dose (n=5) or changing BRC to CAB (n=2). But 22/119 (18.5%) patients remained resistant to DA drugs independent of dose, duration or type of drug used. 14 patients failed to normalize PRL levels despite CAB treatment in doses up to 7 mg/week. Outcome of radiotherapy alone or combined with surgery (n=15): PRL normalization was achieved in 4 patients out of the only 7 assessed at least at 18 months after radiotherapy. Withdrawal of DA therapy revealed 2 cured cases, both after radiotherapy and surgery. Outcome of surgery: Only one patient normalized PRL levels after surgery, but she soon relapsed. Apparently, only one case of acquired resistance to DA drugs was revealed. We found that 15.1% (18/119) of the patients with macroprolactinoma did not finally normalize their serum PRL even after combined therapy approaches (DA + radiotherapy ? surgery), after 79 ? 17.4 months (range 6 to 206 months) treatment total duration and 45.4 ? 19 months (range 3 to 206 months) after radical therapies, respectively.\r\nConclusion: In summary, the resistance was successfully treated in 38% cases (11 out of 29).
