ACTA ENDOCRINOLOGICA (BUC)

Introduction. Vitamin D (VD) deficiency is highly prevalent worldwide. Aim. To assess the prevalence of hypovitaminosis D in HIV-positive Romanian patients compared to controls. Methods. Serum 25OHD concentration was measured in HIV-infected patients and a control sample, matched by age, sex and menopausal status. The 25OHD status was defined as: deficiency < 20 ng/mL (severe deficiency <10 ng/mL), insufficiency 20-30 ng/mL, normal >30 ng/mL. Results. We evaluated 118 HIV-positive patients (72 males, 46 females), aged 36.9±12.2 years. 98.14% of them were on complex antiviral regimens. The B/C hepatitis coinfection rate was 9.3%. The control sample consisted of 119 subjects, (74 males, 45 women). The median and interquartile range for serum 25OHD concentration in patients was 17.6 (9.7, 26.9) ng/mL and 23.7 (18.4, 27.5) ng/mL in controls (p=0.001). Only 15.96% of HIV-positive cases and 12.71% of controls had normal VD status. The percentage of cases with severe VD deficiency was significantly higher in HIV positive cases (23.52%) compared to HIV-negative controls (4.2%, p=0.001). Conclusions. Hypovitaminosis D was identified in 84.04% of HIV-infected patients, but the serum 25OHD concentration was not associated with specific HIV-related factors in our sample. Clinical guidelines regarding VD status determination and supplementation in HIV patients are needed.

Severe hypercalcemia is often caused by primary hyperparathyroidism (PHP), which is not commonly seen in patients with systemic lupus erythematosus (SLE). In this case report a 77 years old woman with a history of SLE develops mild hypercalcemia secondary to unrecognized PHP that leads to a hypercalcemic crisis with a prolonged recovery. Therefore, early diagnostic evaluation of persistent hypercalcemia in patients with SLE is important for detection and appropriate treatment of PHP to avoid a hypercalcemic crisis and associated prolonged morbidity.

Introduction. This case report is the fourth of its type in the medical literature. It describes total thyroidectomy for recurrent relapses of Graves encephalopathy (GE) despite medical treatment. Case presentation. A 33-year-old male presented with impaired consciousness and convulsions. He had postthyroid surgery recurrent Graves’ disease with a goitre. Based on this fact, high thyroid antibodies titres and the exclusion of other causes of such neurological manifestations, he was diagnosed to have GE. This is a rare variant of “encephalopathy associated with autoimmune thyroid disease” (EAATD). Despite the administration of steroid therapy and other standard therapeutic measures, he developed five relapses within 17 months. Total thyroidectomy was advised. Unfortunately, he got another severe attack that required intensive care admission. After three days of discharging, he had urgent total thyroidectomy. The operation went well and for 18 months’ follow-up he had no more attacks. However, thyroid antibodies remained high. Discussion. The report provides details on the diagnosis, standard management and the indication for thyroidectomy for GE. It describes its challenges, precautions, technique and outcomes. It reviews the extent of surgery as well as the clinical and antibody outcomes of the previous three related reports, in comparison with the current one. Conclusion. For medically uncontrolled relapse of GE, thyroidectomy consistently results in ending the attacks. It, therefore, should be put in more consideration in the treatment protocols. On the other hand, one should not depend on antibody levels as a measure of treatment success.

Insulinoma in a patient with pre-existing diabetes mellitus is very rare.\r\nWe report a case of a malignant insulinoma in a 78-year-old patient with type 2 diabetes mellitus who, after 6 years of insulin treatment, experienced recurrent episodes of\r\nhypoglycaemia, with progressive reduction of dosage to cessation. Endogenous hyperinsulinism was confirmed: glucose 35 mg/dL (74- 106), insulin 23.7 &#956;U/mL (7- 17),\r\nand negative test for sulphonylureas in the plasma. Endoscopic ultrasonography, magnetic resonance and axial computer tomography identified a non-resectable pancreatic tumour, an infiltrating mesenteric vein, as well as metastatic lesions in the liver. After chemoembolization of metastases, initial reduction of hypoglycemic attacks occurred. A few months later, hypoglycaemia recurred, and combined treatment with somatostatin analogs and diazoxide was employed. Although hypoglycemic agents are the commonest\r\ncause of hypoglycemia in type 2 diabetes, insulinomas may occur in these patients. A high degree of suspicion for the presence of an insulinoma should be maintained when\r\nunexplained hypoglycemic episodes occur in a patient with previously stable diabetes despite dose adjustment or cessation of the drugs.

Context. Craniopharyngiomas (CPH) are benign tumors, rarely encountered in children, representing 5-6% of all intracranial tumors. Objective. This study aimed to analyze the surgical management and quality of life in a series of CPH pediatric cases. Design. This was a multicenter study performed over a 25-year period (1994 - 2019) in Bucharest. Subjects and Methods. 152 children (0-17 years old) were treated for CPH. Preoperative manifestations were intracranial hypertension, endocrine dysfunction, visual impairment, ataxia, intellectual performance decrease. Results. Considering all surgical approaches used, we advocate for pterional approach to best fit in CPH. We achieved gross-total removal (GTR) in 83 cases (54.4%), near-total resection (NTR) in 13 cases (9%), partial resection (PTR) in 51 cases (33.3%). 5 cases were biopsies (3.2%). Gamma Knife Surgery was performed in 10 cases (6.5%), all recurrences. At 6 months GOS revealed: Good Recovery 70 cases (46.2%), Moderate Disability 62 cases (40.7%), Severe Disability 13 (8.5%), Vegetative State 2 cases (1.3%), Deceased 5 cases (3.2%). Complications were: diabetes insipidus (89.3%); hypopituitarism (66.4%); hypothalamic damage (17.7%); visual deterioration (18.4%). Conclusions. Surgery remains the main option, but GTR complications prove the necessity for a multidisciplinary approach. Outcome predicting factors are: age, tumor size, hydrocephalus degree, hypothalamic dysfunction.

Objective. The association of type 1 diabetes mellitus with autoimmune thyroiditis or with celiac disease is frequently mentioned in literature, but the concomitant presence of these three autoimmune diseases, especially in adults, represents a rarity. Case report. We present the case of a young man with severe generalized oedema admitted to the emergency department and diagnosed with severe hypothyroidism (TSH=100 μUI/mL, fT4 = 0.835 pmol/L) in the context of a long-lasting autoimmune thyroiditis (anti-TPO antibodies 64 UI/mL, anti-TG antibodies 17 UI/mL, the thyroid ultrasonography). At the same time, he was diagnosed with type 1 diabetes mellitus. He was also submitted to further tests which confirmed the diagnosis of celiac disease (endoscopy with intestinal mucosa biopsy, confirmed by immunological tests). The association of these three diseases slows down the process of reaching a final diagnosis and delays the adoption of a therapeutic strategy. Conclusion. This case underlines the difficulty of differential diagnosis of severe oedema syndrome with polyserositis in a patient with polyglandular autoimmune syndrome. Whenever there is a suspicion of the association of these autoimmune diseases, the evolution of the patient is unpredictable and most medical results are highly dependent upon the decision of applying a concomitant treatment.

A 57 years old woman was diagnosed with welldifferentiated lung neuroendocrine tumor (NET) by laboratory assessment, computed tomography (CT), contrast-enhanced magnetic resonance imaging (MRI) and bronchoscophy with transbroncial biopsy of nodular lung lesion located in the right lower lobe. Staging Ga-68 positron emission tomography-CT (PET-CT) showed two pathological uptake regions in the superior segment of the right lung lower lobe (SUVmax: 80.61) and 6th thoracic vertebral body (SUVmax: 3.70). Contrast-enhanced MRI findings suggested that vertebral lesion may be compatible with atypical hemangioma or osseous metastasis due to T1 isointensity, T2 hyperintensity and contrast-enhancement on the lesion. Therefore, characteristic imaging findings of hemangioma were seen on axial and sagittal or coronal sections of CT, respectively called as ‘polka dot’ and ‘corduroy cloth’. Thus the mild vertebral Ga-68 DOTATATE uptake was accepted as false positive finding. Surgical intervention was decided. She underwent a right lung lobectomy. The last follow-up of the patient was done 2 years after the initial diagnosis. The follow-up Ga-68 DOTATATE PET-CT revealed no pathological increased uptake in the whole-body except the 6th vertebra showing similar uptake (SUVmax: 3.50) with the previous scan without size increase on CT. The patient was asymptomatic with normal serum chromogranin A level.

Context. Previous studies have associated overt/ subclinical hypothyroidism and obesity but have failed to confirm a causative relationship between them. Confusion is even more for subjects with Hashimoto’s Thyroiditis (HT). Objective. In this study, we aimed to evaluate the fat distribution and metabolic profile of subjects with euthyroid HT as well as to establish an appropriate cut-off level of TSH for the development of metabolic syndrome (Mets) in both groups. Patients and Methods. All subjects were euthyroid whether under levothyroxine replacement or not. We recruited 301 volunteers (99 with HT and 202 without thyroid autoimmunity). Together with some metabolic variables, we measured the waist circumference, hip circumference, neck circumference manually; the total body fat with a body composition analyzer; and the visceral fat/ trunk fat percentage via abdominal bioelectrical impedance analysis. Results. A significant positive correlation was established between TSH levels and insulin, fasting plasma glucose, HOMA-IR and body mass index (r=0.28; p<0.001; r=0.27; p<0.05: r=0.32; p<0.001: r=0.13; p<0.05 respectively). The prevalence of Metabolic Syndrome (Mets) was comparable in HT and control groups (27.3% vs. 30.7%; p>0.05). The prevalence of Mets was similar when HT subjects using levothyroxine or HT subjects with accompanying thyroid nodules were taken into consideration. Similarly, anthropometric and metabolic parameters were similar in both the HT group and the control group. We were unable to establish the TSH cut-off level by ROC analysis with desired sensitivity and specificity (AUC: 0.563 with 95% C.I. p=0.35; standard error 0.76). Conclusions. Although weight gain is frequently encountered in subjects with HT, such subjects with thyroid function tests in the euthyroid range have a similar prevalence of Mets and similar metabolic and anthropometric measurements compared to subjects without autoimmunity.

Introduction. The polyglandular autoimmune syndrome (PAS) type III is a rare condition defined as the coexistence of autoimmune thyroid disorder with other endocrine autoimmune diseases, including type 1 diabetes, without adrenal dysfunction. PAS may associate with other non-endocrine autoimmune diseases, overlapping with the multiple autoimmune syndromes (MAS). We present a case of PAS III/ MAS type 3, including autoimmune thyroiditis, autoimmune diabetes, vitiligo, lupus erythematosus, associated with adult-onset atopic dermatitis, a combination not reported previously. Case report. A 40 years old woman, registered as nurse working in dialysis unit, previously diagnosed with vitiligo, euthyroid autoimmune thyroiditis and disseminated granuloma annulare, with personal and familial history of atopic disorders, presented in our clinic for disseminated eczematous and lichenoid cutaneous rashes. She was tested positive for antinuclear, anti-double stranded DNA and anti-histone antibodies, with inflammatory syndrome and marginal lymphopenia and she was diagnosed with systemic lupus erythematosus (SLE). Subsequently, moderate hyperglycemia, positive anti-glutamic acid decarboxylase antibodies and low C-peptide level prompted the diagnosis of autoimmune diabetes. Recurrent flexural eczematous rashes, with negative epicutaneous tests but positive specific IgE tests for common allergens fulfilled the clinical criteria for the diagnosis of atopic dermatitis. The clinical, immunological and glycemic status were controlled with low doses of oral prednisone (<0.5 mg/kg), methotrexate (10mg/week), antimalarials, metformin, emollients and photoprotection. After changing her workplace, the immunosuppressive treatment could be discontinued, and the patient maintained normal immunological and biochemical profile at 6 months follow-up. This case brings a unique perspective on the evolution, associations spectrum and the management challenges of endocrine polyautoimmunity associated with atopic diathesis.

Background. The implementation of assisted reproductive techniques (ART) is a complex treatment requiring both a good cooperation between various professional groups in the fertility centre, and the patient’s and her partner’s cooperation. Accordingly, there are many sources of failure, such as using the wrong medication or not considering optimal times. If there is an artificial application of the ovulation induction injection, the success of the treatment is endangered and in some cases the cycle is discontinued, if the patient failed to administer the drug correctly. An alternative to cycle cancellation might be the maturation of the oocytes in vitro. We report on a 31-year-old patient in whom we performed an oocyte retrieval procedure 24 hours after triggering ovulation followed by in vitro maturation of the immature oocytes over a period of more than 12 h. The treatment resulted in a healthy, ongoing pregnancy.
