Comparison between surgical and non-surgical management of primary hyperparathyroidism during pregnancy: a systematic review.

PURPOSE: The management of primary hyperparathyroidism (PHPT) during pregnancy may be surgical or conservative. This study compared adverse outcomes between surgical and non-surgical treatments. Additionally, the study investigated the correlation between serum calcium values and complication rates. METHODS: A systematic review of retrospective studies, case series, and case reports. Biochemical parameters, interventions, and outcomes of each pregnancy were recorded. The study population comprised two groups: the non-surgical and surgical groups. Adverse outcomes were categorized as maternal, obstetric, or neonatal. RESULTS: The surgical and non-surgical groups consisted of 163 and 185 patients, respectively. A positive correlation was observed between the mean maternal gestational calcium value and both maternal and obstetric complication. Neonatal complications were more prevalent in patients treated conservatively across all maternal calcium values (p < 0.001). No significant differences were observed in maternal outcomes and overall obstetric outcomes between the study groups, albeit a higher mean serum calcium value in the surgical group (12.3 mg/dL) compared with the non-surgical group (11.1 mg/dL). CONCLUSIONS: Given the significantly lower neonatal adverse outcomes in the non-surgical group compared to the surgical group, along with non-inferior maternal and obstetric outcomes in the surgical group, the overall data of this study suggest that parathyroidectomy is favorable to non-surgical management even in cases of mild hypercalcemia.

Subclinical acromegaly: to treat or not to treat?

Patients with acromegaly usually present with the classical signs of acromegaly, whereas patients without the specific signs or symptoms are rarely diagnosed. This unique entity can be named "subclinical acromegaly". This was a retrospective study. Our study group consisted of 6 patients (4 females) with incidentally diagnosed acromegaly, most following head MRI for unrelated reasons and without the specific signs of acromegaly. Mean age at diagnosis was 48.8 ± 19.2 years. Baseline IGF-1 ranged between 1.3-2.0 × upper limit of normal (ULN). MRI depicted a pituitary microadenoma in 5 patients, and one patient presented with a 12 mm intra-sellar macroadenoma. Mean calculated SAGIT clinical score was 4.8. Three patients underwent trans-sphenoidal resection; two achieved hormonal remission and one improved but did not normalize IGF-1 following surgery. Four patients (including one following surgery) were given somatostatin analogs, and three normalized IGF-1. Several patients improved clinically following treatment, reporting improvement in snoring, hypertension, or weight loss, and pituitary adenoma decreased in size in 2 patients that responded to medical treatment. We report a series of 6 patients with very mild and subclinical acromegaly. It is uncertain whether all such patients will gain clinical benefit from treatment, but most experienced clinical improvement due to treatment.

Acromegaly: Clinical Care in Central and Eastern Europe, Israel, and Kazakhstan.

Acromegaly is a rare condition typically caused by benign pituitary adenomas, resulting in excessive production of growth hormone. Clinical manifestations of acromegaly are diverse, varying from the overgrowth of body tissue to cardiovascular, metabolic, and osteoarticular disorders. Symptoms may emerge slowly, overlapping with other diseases and often involve many different healthcare specialists. In the last decade, efforts to provide an accurate and timely diagnosis of acromegaly have improved disease management and clinical experience. Despite this progress, marked differences in the diagnosis, treatment, and management of acromegaly exist from country-to-country. To address these inconsistencies in the region comprising Central and Eastern Europe, Israel, and Kazakhstan, a panel of acromegaly experts from 13 of these countries was convened. Acromegaly experts from each country provided available information on the approaches from their country, including regional treatment centers and multidisciplinary teams, treatment access, reimbursement and availability, and physician education, disease awareness, and patient advocacy. Across several areas of acromegaly management, divergent approaches were identified and discussed, including the provision of multidisciplinary care, approved and available treatments, and disease awareness programs. These were recognized as areas of potential improvement in the management of acromegaly, in addition to participation in national and regional acromegaly registries. Further experience exchange will facilitate the identification of specific strategies that can be adapted in each country, and widespread participation in acromegaly registries will enable their evaluation. It is anticipated that this approach will support the optimization of acromegaly patient care across this region.

Phosphaturic mesenchymal tumors among elderly patients: a case report and review of literature.

Phosphaturic mesenchymal tumor (PMT) represents a rare cause of osteomalacia. The clinical signs and symptoms are vague and these lead to diagnosis delay. In the presence of hypophosphatemia and relatively high urine phosphate excretion, this entity should be taken into consideration in the deferential diagnosis of osteomalacia. In the present article, we report 81-year-old man presented to our clinic for evaluation due to osteopenia. His laboratory results disclosed hypophosphatemia, relatively increased urine phosphate excretion and increased level of intact fibroblast growth factor 23 (FGF23). A 68Gallium DOTATATE PET/CT revealed pathological uptake in the upper aspect of the left shoulder adjacent to the coracoid process. For suspected PMT a wide resection of the tumor was performed and pathological findings were consistent for PMT. Laboratory tests were normalized postoperatively. Reviewing the literature, we had identified 33 reported cases of PMTs among elderly patients age ≥70 years. Unlike previously reported data, where tumors predominantly localized in the lower extremities and pelvis, our search disclosed a high rate of tumor localization (10 cases - 33.3%) in the head with equal number of tumors (14 cases - 42.4%) localized in the head and upper extremity as well as in pelvis and lower extremity. The present case describes unique tumor localization in an elderly patient and our literature search demonstrated for the first time a high rate of tumor localization in the head among this group of patients. Learning points: PMTs represent a rare entity that should be considered in the differential diagnosis of elderly patients presented with persistent hypophosphatemia. Unlike previously reported data, head and neck tumor localization is frequent among elderly patients. 68Gallium-conjugated somatostatin peptide analogs, such as 68Ga-DOTATATE PET/CT demonstrated the greatest sensitivity and specificity for tumor localization in patients with phosphaturic mesenchymal tumors (PMTs). Wide tumor resection using intraoperative ultrasound is of major importance in order to ensure long-term cure.

PASIREOTIDE FOR A PATIENT WITH ACROMEGALY AND CHRONIC KIDNEY DISEASE ON HEMODIALYSIS.

OBJECTIVE: Acromegaly is a rare disease. Medical management with somatostatin analogs and the growth hormone receptor antagonist pegvisomant can normalize insulin-like growth factor-1 (IGF1) levels after failed surgery and decrease mortality and comorbidities. We present a case report of a patient with acromegaly on chronic hemodialysis resistant to first-generation, long-acting somatostatin analogs with remarkable response to pasireotide long-acting release (PAS-LAR). METHODS: A 66-year-old woman with acromegaly and chronic renal failure on hemodialysis resistant to lanreo-tide autogel (at 120 mg) was treated successfully with PAS-LAR. RESULTS: Acromegaly was diagnosed in 1996 and transsphenoidal resection of macroadenoma was performed with normalization of IGF1 levels. Nine years later, recurrence of the tumor led to a second operation. Lanreotide autogel was initiated due to persistently high levels of IGF1, but the patient was resistant to treatment. A positive response was observed with pegvisomant. However, the patient was nonadherent and treatment was discontinued. PAS-LAR was initiated and normalization of IGF1 and growth hormone was achieved. CONCLUSION: This is the first case report of a patient with acromegaly on chronic hemodialysis who was resistant to first-generation, long-acting somatostatin analogs and successfully treated with PAS-LAR.

Sodium Glucose Co-transporter Inhibitors in Patients with Acromegaly and Diabetes.

Acromegaly per se predisposes to diabetes. Somatostatin analogs (SSAs) have an overall neutral effect on glycemic control. However, a marked increase in hyperglycemia was observed recently since the introduction of pasireotide long-acting release (PAS-LAR). Sodium glucose cotransporter inhibitors (SGLT2is) have proven their efficacy, cardiovascular safety, and superiority in the management of type 2 diabetes mellitus (T2DM). However, this class is rarely recommended for patients with diabetes and acromegaly. A decreased circulating insulin level is considered unique for this class and might have a beneficial role in the growth hormone-insulin-like growth factor-I (GH-IGF-I) axis. Therefore, SGLT2is should be considered in the management of diabetes in patients with acromegaly. This article highlights the role of this novel class for the management of diabetes in patients with acromegaly.

Efficacy and safety of long-acting pasireotide in patients with somatostatin-resistant acromegaly: a multicenter study.

INTRODUCTION: Pasireotide, a multi-somatostatin receptor (SSTR)-ligand with high affinity for SSTR5 was recently approved for acromegaly treatment. PATIENTS AND METHODS: A retrospective multicenter study investigating the efficacy and safety of long-acting (LAR) pasireotide treatment in 35 patients (20 males) with active acromegaly (28 macroadenomas). RESULTS: Mean baseline insulin-like growth factor-1 (IGF-1) at diagnosis was 3.1 ± 1.3 × ULN. All but five patients have undergone pituitary surgery and six received sellar radiotherapy. All remained with active acromegaly despite first-generation somatostatin analogue (SSA) treatment. Immediately before pasireotide-LAR initiation, eighteen patients were under SSA monotherapy and one with pegvisomant. The remaining patients received combination therapy with SSA and pegvisomant, n = 9 (two received cabergoline also); SSA and cabergoline, n = 4; pegvisomant and cabergoline, n = 1. Two were untreated. Mean IGF-1 was 1.76 ± 0.9 ULN before pasireotide. Pasireotide-LAR starting dose was 40 mg/4 weeks in most patients. IGF-1 normalized in 19 patients, IGF-1 between 1-1.2 × ULN was reached in five, and in additional two patients IGF-1 was significantly suppressed. No effect was seen in nine patients. Pasireotide dose was reduced by 20 mg in six patients with excellent response, with preserved IGF-1 control in five. Severe headaches in six patients disappeared or improved with pasireotide. Side effects consisted of symptomatic cholelithiasis in one patient and deterioration of glucose control in 22 patients, requiring initiation or intensification of antidiabetic treatment in seventeen. One patient developed diabetic ketoacidosis. CONCLUSIONS: In the real-life scenario ~54% of patients with acromegaly resistant to first-generation SSA, may normalize IGF-1 with pasireotide; however, 63% experienced glucose control deterioration.

Risk stratification of patients with diabetes and the role of sodium glucose co-transporter inhibitors 2 during Ramadan fasting.

The month of Ramadan represents a golden opportunity for better management of patients with diabetes not only during Ramadan month, but also through the entire year. Pre Ramadan period is crucial for evaluating and preparing patients with diabetes intending to Fast Ramadan. The risk stratification categories should take into consideration patients with diabetes having specific conditions such as nephrotic syndrome who are predisposed to thrombosis independent to their estimated glomerular filtration rate and glycated haemoglobin. Furthermore, population-specific conditions such as nomadic Bedouins living in remote areas should be considered as part of the very high risk category for fasting Ramadan. Published data regarding the use of sodium glucose co-transporter 2 inhibitors during Ramadan is very limited. Dapagliflozin was the only agent studied during Ramadan. Therefore, it is suggested to categorize this group of agents differently from other agents such as metformin and incretin based therapy studied vastly during Ramadan.

Type 2 Diabetic Patients Fasting on Ramadan in Israel.

BACKGROUND: Fasting during Ramadan is not mandatory for diabetic patients, but the majority of type 2 diabetic patients insist on fasting despite the potential risks. These patients represent a challenge not only for themselves, but also for healthcare practitioners during this period. This review provides, for the first time, healthcare practitioners in Israel with guidelines and recommendations that fit the Muslim population for better management of diabetic patients who fast during Ramadan, taking into consideration recently published recommendations and therapies available in Israel.

Simultaneous occurrence of medullary and papillary thyroid microcarcinomas: a case series and review of the literature.

INTRODUCTION: Papillary thyroid microcarcinoma has been demonstrated to present in association with medullary thyroid carcinoma, however, medullary thyroid carcinoma and papillary thyroid carcinoma represent rare entities. In recent years this rarity has been increasingly observed. The pathogenesis is still controversial. Genetic analysis of RET proto-oncogenes in cases of simultaneous papillary thyroid carcinoma and medullary thyroid carcinoma has so far provided conflicting results; although it seems that germline mutations play a potential role in the development of both histological types. CASE PRESENTATIONS: This paper describes four rare cases of simultaneous medullary thyroid carcinoma and papillary thyroid microcarcinoma with unique features:Case one was a 43-year-old Jewish woman, born in Israel, daughter of a Latvian immigrant mother and a father born in Israel. Case two was a 44-year-old Arab woman born in Israel. Case three was a 45-year-old Jewish woman, born in Israel, daughter of Moroccan immigrant parents and is unique for the presence of lymph node metastatic medullary thyroid carcinoma, and one lymph node with metastatic papillary carcinoma found in the same side. Case four was a 77-year-old Jewish woman, born in Iraq. These cases are unique in their composition of thyroid carcinoma, consisting of histologic features of medullary thyroid carcinoma, papillary thyroid microcarcinoma, and follicular thyroid adenoma. The four cases represent different ethnicity groups that live in north Israel, and case four is notable for the advanced age of the patient (77 years). CONCLUSION: These four cases add more data supporting the coincidental coexistence of papillary thyroid microcarcinoma and medullary thyroid carcinoma; our results may suggest that the simultaneous occurrence of medullary thyroid carcinoma and papillary thyroid microcarcinoma is generally a simple reflection of this coincidence. Endocrinologists and pathologists should be aware of this entity. The pathologist can play a pivotal role in identifying papillary thyroid microcarcinoma in concurrent existence with medullary thyroid carcinoma.

Efficacy of long-term lanreotide treatment in patients with acromegaly.

We investigated the effectiveness of lanreotide for the treatment of active acromegaly in a retrospectively multicenter case series including 53 patients (24 male, 29 female; mean age at diagnosis, 49.5 +/- 13.9 years) with acromegaly treated with lanreotide in nine different centers. Mean tumor diameter was 20 +/- 13 mm; mean basal levels of growth hormone (GH) and insulin-like growth factor I (IGF-I) were 21.3 +/- 26.3 and 579 +/- 177 mug/l, respectively. The primary mode of treatment was surgery in 70% of patients. Twenty-nine patients received only lanreotide (Prolonged Release, Autogel), whereas 24 subjects were also treated with octreotide at another treatment stage. Primary therapy with lanreotide was administered in five patients. Maximal monthly dose of lanreotide Autogel (n = 44) was 60 mg in 45%, 90 mg in 26%, 120 mg in 21% and 180 mg in 8%. During 36 months of lanreotide treatment, mean IGF-I levels decreased from 443 +/- 238 to 276 +/- 147 mug/l (P < 0.001), and mean GH levels, from 5.2 +/- 6.4 to 3.2 +/- 3.0 mug/l (P < 0.001). IGF-I levels normalized in 51% of patients and decreased by >50% towards normal in 32%; the normalization rate was higher in women (65%) than men (33%, P = 0.04). Safe random GH levels (
