ACTA ENDOCRINOLOGICA (BUC)

Introduction. Obesity was considered to protect against osteoporosis. Recent studies indicate the opposite.\r\nThe study aimed to see if adipose tissue has a protective effect on bone mass and if adipocytokines can explain the\r\nrelationship between obesity and osteoporosis.\r\nSubjects and methods We designed a study enrolling 83\r\npostmenopausal women, aged over 60, without diagnosed or treated osteoporosis and no secondary osteoporosis. We formed 3 groups- group 1- osteoporosis and metabolic syndrome (MetSyn), group 2- osteoporosis, group 3- MetSyn.\r\nWe evaluated the hematological, biochemical profile, bone turnover markers and adipocytokines. DXA of the spine and\r\nthe hip (left) was performed on all the enrolled women. Insulin resistance was appreciated using HOMA index. Metsyn\r\nwas defined using the International Diabetes Federation?s criteria.Results were statistically analyzed using SPSS program, version 15.\r\nResults. All groups were vitamin D insufficient with lower vitamin D, osteocalcin and adiponectin levels in the\r\ngroups with MetSyn and higher leptin levels. BMI correlated positively with spine BMD, while leptin correlated positively with hip BMD, pointing out to the protective effect of obesity against osteoporosis due to leptin?s involvement.\r\nConclusion. Obesity seems to have a protective effect against osteoporosis, probably due to leptin.

Abstract Context. Autoimmune progesterone dermatitis (AIPD) is a rare, cyclical dermatosis, with variable clinical presentation, occurring exclusively or being aggravated during the luteal phase of the menstrual cycle, when levels of progesterone rise. Its pathogenesis is still unclear. AIPD is thought to occur as an autoimmune reaction to endogenous possibly modified progesterone, but it could also be triggered by exogenous progesterone exposure. AIPD is a diagnosis of exclusion. Usually there is no or limited response to oral H1 antihistamines and a partial response to steroids. Ovulation inhibitors represent the specific treatment. Case report. We report a case of AIPD in an 18-year-old nulliparous patient with no medical history of allergic diseases and no exposure to oral contraceptive pills. AIPD was suspected based on the clinical picture (recurrent cyclical eczematous eruption on the face and abdominal area) and confirmed by positive intradermal test and positive progesterone challenge. This diagnosis was supported by the result of the skin biopsy, which also helped to exclude other dermatoses with premenstrual aggravation. The rash responded satisfactorily to treatment with a combination of oral contraceptives, levonorgestrel and estrione, which is currently considered first line therapy. Conclusions. This case is of particular interest due to the lack of previous pregnancy or exposure to progesteron therapy. Recurrent, cyclical eruptions in fertile women should raise the suspicion of AIPD. If early recognized, the patient may benefit from non-invasive treatment that improves significantly the quality of life.

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.

The study comments unusual associations between thyroid and cutaneous autoimmunity: Graves-Basedow disease (GBD), vitiligo and alopecia areata (AA) starting from two cases. In the first case, a woman with systemic lupus erythematosus (SLE), data were recorded from 38 to 49 years as follows: vitiligo (at 38 ys), alopecia areata (4-6 months afterwards), SLE (after 2 ys) and then GBD (after 8 ys). After 3 years, hyperthyroidism has spontaneously vanished, but vitiligo, AA, leucothrichia, SLE, goiter and ophthalmopathy persisted. In the second case, a man, data were recorded from 26 to 70 years and the disease was associated with psoriasis. The sequence of diseases was: vitiligo (at 26 ys), AA and GBD (after 8 ys), followed by iatrogenic 131I hypothyroidism, and psoriasis (after 33 ys). Vitiligo and AA have spontaneously vanished before GBD began. These multiple immune syndrome associations bring up the question: ?Are these diseases multiple associations or a unique immune disease?? A possible point of view, related to immune network, suggests that these multiple associations represent in fact only one process, therefore they represent not many diseases, but different expressions in time (sequence) and space (organ-lesion) of the disease of the immune network.

Background. Hidradenitis suppurativa (HS) is a chronic, debilitating disease with a profound impact on the quality of life of patients. Objectives. To describe a rare case of HS with postmenopausal onset, to review the literature data regarding late onset HS and to discuss the current knowledge on the role of endocrine abnormalities in the development of HS. Case report. We report the case of a 68-year-old patient in whom HS occurred 10 years after menopause. She was referred to our clinic for the presence of an open fistula on the left groin, fibrotic scars and visible alteration of the vulvar anatomy due to numerous surgical interventions. The patient shared features of the metabolic syndrome (obesity, arterial hypertension, dyslipidemia, aortic atherosclerosis), but showed no signs of virilism and no hormonal abnormality. HS was controlled using antiseptics, topical retinoids and antibiotics. Conclusions. This case is of particular interest given the late onset of HS, long time after menopause. The development of HS requires a complex interaction between genetic predisposing factors, endocrine dysregulation, metabolic alterations, bacterial overgrowth and an aberrant inflammatory response. Evidence points to an important role of sex-hormones in the emergence and progression of the disease, but the underlying mechanisms are still unclear. A better understanding of HS pathogenesis is needed to elucidate the precise way in which endocrine factors influence the disease onset and course. This would guide the way to novel therapies and a better control of this challenging disease.

Context. Advanced skin cancers have high mortality and morbidity, and early detection is crucial for prognosis. Information regarding the patterns of skin self-examination and tumor early detection in the Central and Eastern Europe is scarce. Objective. Analyze the gender differences in the practices and attitudes related to skin cancer early detection of skin cancer patients in Romania. Methods. Prospective questionnaire- based survey of patients with confirmed diagnosis of skin cancer, registered in a university reference center for dermatooncology between 2011-2012. Results. 122 skin cancer patients completed the survey (response rate 72%). Female skin cancer patients reported lower level of education and likelihood to receive a medical full skin examination. Women were more likely to check their own skin and to detect suspicious lesions on themselves and their partners than men. They delayed longer the presentation to a physician after noticing a suspicious lesion (11.4 months vs. 6.4 months median). 90.76% of all skin cancer patients were not warned by any doctor about their skin cancer risk; 30% of them never check their skin. Conclusions. Women tend to be more concerned about their skin than men, but receive less medical attention and delay longer the diagnosis. Our study also signaled an urgent need of improving the patients and physicians education for skin cancer early detection in Romania.

Context. Chronic idiopathic urticaria (CIU) is often associated with autoimmune thyroiditis (AT). Objective. The aim of this study was to analyze the clinical particularities of patients with CIU associated with AT and to evaluate the efficacy of dapsone in such patients. Design. We performed an observational study of patients hospitalized in our clinic between January 2010 - December 2013 for moderate/severe chronic urticaria (CU). Subjects and Methods. Data regarding medical history, clinical, paraclinical findings, coexistence of AT and response to treatment were compared between patients with CU and AT and those without AT. Patients continued oral H1 antihistamines. Severe flares required systemic corticotherapy. 11 patients with refractory CIU associated with AT received dapsone treatment. Levothyroxine was administered in patients with hypothyroidism. Results. Among the 210 patients admitted for CU, 39 (92% female) were diagnosed with CIU associated with AT. Patients with CIU associated with AT had a slightly longer disease duration, a higher prevalence of angioedema (25.6% vs. 16.7%) and a more frequent need of systemic corticotherapy for urticaria exacerbations (46.2% vs. 30.4%). All 39 patients achieved significant clinical improvement after a mean period of 4 weeks based on urticaria activity score (UAS) 7 (p<0.0001). Conclusions. Assays for thyroid autoantibodies and thyroid function should be part of the workup in patients with CU, enabling the diagnosis of autoimmune urticaria. Without correction of the underlying autoimmune mechanisms, CU may persist regardless of conventional treatment. Dapsone represents a therapeutic option in autoimmune CU.
