RESUMEN
OBJECTIVE: Type1 diabetes mellitus may be associated with celiac disease. The prevalence of celiac disease as determined by screening among adult patients with type 1 diabetes is high with rates of 1.07.8% in Europe and U.S.A. The aims of the study are to determine the prevalence of celiac disease in adults with type 1 diabetes in Tunisia. METHODS: 348 consecutive adult patients with type1 diabetes were investigated prospectively and screened for celiac disease. The mean age was 28.45+/-10.74 years old. There were 176 females and 172 males. For the screening of celiac disease, we used immunoglobulin A (IgA) anti-endomysium (EMA) antibodies determined by an indirect immunofluorescence method. Anti-transglutaminase (tTG) antibodies were determined by an ELISA method. Those patients with positive results for anti EMA and or tTG were proposed for duodenal biopsy. RESULTS: 14 patients were positive for anti EMA and had high or a weak positive level of tTG antibodies. One patient from this group was already known to have celiac disease. Only 8 patients consented to biopsy and morphological changes were consistent with celiac disease in all cases. Prevalence of biopsy-proven celiac disease was 2.3% (95% CI=1.0-4.5%). CONCLUSION: The present study confirms that celiac disease of adults is prevalent in type 1 diabetic patients in Tunisia. Serological screening for celiac disease in type 1 diabetes is important because many patients are asymptomatic and most are detected by the screening.

Endocrine disorders seen in antiphospholipid syndrome are rare. To date, these disorders have generally involved Addison's disease. Recently reports have appeared of a few cases of primary or secondary hypopituitarism associated with primary antiphospholipid syndrome. We report the case of a young female patient who presented neuroendocrine symptoms during the postpartum period associated with an antiphospholipid syndrome. Hormone assessment showed complete anterior hypopituitarism and antiphospholipid antibodies were positive. We discuss the clinical, biological and radiological features observed in our patient and compare results with cases reported in the literature. This case illustrates the importance of screening for antiphospholipid syndrome in the etiological work-up of hypopituitarism associated with a history of recurrent thrombosis.

To assess the effectiveness of bromocriptine (BRC) as primary therapy in reducing the size of PRL-secreting macroadenomas with extra-sellar extension, we conducted a multicenter study in 29 patients without prior radiotherapy. Clinical presentation, response to medical treatment and long term follow-up of 29 patients with macroprolactinoma (pituitary mass more than 10 mm in diameter) were analysed. There were 19 women for 10 men. Mean age was 33 years. An hypogonadism was present in 94% of women vs 57% for men. Headaches and or visual abnormalities were present in 68% of women vs 90% of men. The mean basal serum prolactin level before treatment was 1 501 ng/ml: 202 ng/ml for women (range: 70-478 ng/ml) and 3 870 ng/ml for men (range: 100-20 476 ng/ml) and was correlated to tumoral size. 25 patients were treated with BRC as primary therapy with a mean dose of 9,7 mg/day (13 mg/day in men and 8 mg/day in women). BRC no malized serum PRL levels in all men and in 17/19 women over a mean period of 6 months, ranging from 3 to 72 months in both sexes. Tumor size was reduced by more than 50% in 18/29 patients (62%) with secondary empty sella in 5 patients and by less than 50% in 11 patients. Visual field improved in most of the patients in whom it was initially abnormal. Reduction in size was quite fast in most of patients but slower in some of them. The cumulative radiological response to BRC increased with time. Therefore, it appears that prolonged medical therapy is effective and safe in macroprolactinomas.

OBJECTIVES: The prevalence of mycotic infection seems to be higher among diabetic patients than in the non-diabetic population. The aims of this study were to determine the frequency of mycosis and to compare clinical and fungal results. PATIENTS AND METHODS: This transversal study included 307 type 1 and 2 diabetic patients admitted between January 1998 and January 2000. A dermatologist examined all patients. The mean age was 44 +/- 17 years and the duration of diabetes 8 +/- 6 years. Patients with suspected lesions underwent mycological examination. RESULTS: Clinical signs of presumed fungal infection were found in 61% of patients, but mycosis was confirmed only in 30%. Fungal foot infection accounted 38% of the patients, mostly due to dermatophytes (94%). The commonest localizations of dermatophytes were interdigital (60%) followed by onychomycosis (30%). The main fungal agent was Trichophyton rubrum. The main risk factors for fungal infections were the age of patients (P = 0.0003) and duration of diabetes (P < 0.05). Interdigital foot localization of dermatophytes was correlated to age (P < 0.0001) and to the male gender (P < 0.01). The frequency of dermatophytes in nails was higher in type 2 diabetic patients (P < 0.01). Vulvovaginal candidosis and interdigital dermatophytes were more frequent in obese than in non-obese patients. The accuracy and specificity of direct examination were respectively 85% and 79%. CONCLUSION: The high frequency of mycosis in diabetic patients at hospital is demonstrated. The main risk factors were age, male gender and obesity.
