RESUMEN
BACKGROUND: There is convincing evidence that obstructive sleep apnea (OSA) is highly associated with impaired glucose metabolism. OBJECTIVES: Analyze the prevalence of OSA in type 1 and type 2 diabetes mellitus (DM) patients. Evaluate the influence of OSA on glycemic control. METHODS: The adult patients with diabetes mellitus (DM) followed in the department of internal medicine were referred to our Sleep Unit. A home respiratory polygraphy was then performed on all patients with body mass index (BMI) <40 kg/m(2). The glycemic control was assessed by the value of glycated hemoglobin (Hba1c) in the previous 3 months. RESULTS: A total of 46 patients were studied (20 men and 26 women), the mean age was 50±15 years and mean BMI was 28.6±4.9 kg/m(2). The mean Hba1c was 8.3±1.2. Twenty three patients had type 2 DM and 23 patients had type 1 DM. Twenty nine patients (63.0%) had OSA and 8.7% had severe OSA (AHI>30/h). The mean CT90 was 5.3±12.5 and the mean AHI was 13.6±18.3. The mean AHI was similar between type 1 and type 2 DM (15.7±24.5 Vs 11.6±8.9; p=0.46). The AHI was not correlated with the BMI. Type 2 DM patients with poor glycemic control (HbA1c>7.5%) had a significantly higher mean AHI (14.3±9.0 vs 6.4±6.2; p=0.038). This difference did not remain significant after adjustment for BMI (p=0.151). CONCLUSIONS: The prevalence of OSA in type 1 DM is similar to that found in type 2 DM. We note the high prevalence of OSA in younger patients with type 1 DM.

Endocarditis is a rare and serious complication of brucellosis and is the main cause of death in this pathology. Diagnosis requires a high level of suspicion and is based on the association of epidemiological, clinical and serological elements. Echocardiography plays a crucial role in early diagnosis, as well as in identifying predisposing heart disease and local complications typical of this pathology. Treatment is not consensual; most authors recommend an early surgical approach, due to the degree of tissue destruction caused by Brucella and the high rate of recurrence. Nevertheless, other authors stress the need for prognostic stratification of each case and support conservative treatment in low-risk cases. This article describes the case of a patient with brucella endocarditis that was treated medically and reviews the relevant literature.
