BackgroundComorbid depression in diabetes has been suggested as one of the possible causes of an inadequate glycemic control. The purpose of this study was to investigate the association between major depression and the glycemic control of type 2 diabetes mellitus (T2DM).MethodsSeventy T2DM patients were evaluated. They underwent a psychiatric examination using the following instruments: Structured Clinical Interview for DSM-IV and Beck Depression Inventory. The diabetes status was assessed in the short-term (glycemia, glycated hemoglobin) clinical control.ResultsThe presence of current depression was observed in 18.6% (13/70). In addition, type 2 diabetes patients who displayed depression evidenced higher levels of glycated hemoglobin (8.6 ± 2.0 vs. 7.5 ± 1.8; p = 0.05) when compared to those who did not exhibit a mood disorder.ConclusionsIn our sample, the presence of depression seems to impact on the short-term control of T2DM. The authors discuss the clinical utility of these findings in the usual treatment of diabetes.

A presença de depressão no paciente com diabetes mellitus (DM) parece relacionar-se a alterações no curso clínico da doença. O objetivo deste trabalho é realizar uma revisão sistemática sobre a associação entre o DM e depressão. Foi realizada uma pesquisa bibliográfica utilizando as bases de dados MEDLINE e LILACS para identificar artigos relevantes, publicados entre 1990 e 2001, que avaliassem esta associação. Foram analisadas informações referentes à prevalência, ao impacto e ao tratamento da depressão no DM. A prevalência de depressão no DM variou de 0 a 60,5%. Sintomas depressivos relacionaram-se a um pior controle glicêmico, a um aumento e a uma maior gravidade das complicações clínicas, a uma piora da qualidade de vida e ao comprometimento de aspectos sociais, econômicos e educacionais ligados ao DM. O tratamento da depressão está relacionado à melhora dos níveis glicêmicos, podendo contribuir para um melhor controle de diversos aspectos relacionados ao DM. The presence of depression in a patient with diabetes mellitus (DM) seems to be related to changes in the clinical course of the disease. The purpose of this study is to perform a systematic review on the association of DM and depression. A bibliographic search was performed using the MEDLINE and LILACS databases to identify relevant articles, published from 1990 to 2001, which evaluate this relationship. Information concerning prevalence, impact and treatment of depression in DM were analyzed. The prevalence of depression varied from 0 to 60.5%. The presence of depressive symptoms were associated with a poor glycemic control, an increase in the number and severity of clinical complications, a worse quality of life and impairment of social, educational and economic aspects related to DM. The treatment of depression is associated with an improvement in glycemic levels, which may contribute to a better control of several aspects related to DM.

Hypoglycemic episodes after obesity surgery are not always related to dumping syndrome. The persistence of hypoglycemia in spite of nutritional counseling should raise the possibility that there may exist other causes. Insulinoma, the most common cause of endogenous hyperinsulinemia, should be investigated in these patients, since it is a tumor that can be cured.

The aim of this study was to translate into Portuguese and to assess the reliability of an instrument for the diagnosis of diabetic distal polyneuropathy (DPN). The process for translation and adaptation into Portuguese of the Neuropathy Symptom Score (NSS) and the Neuropathy Disability Score (NDS) was performed following internationally standardized procedures. The instruments were applied by 2 raters in 57 consecutive subjects. Spearman correlation was used to evaluate the reliability and Cronbachs' alpha to evaluate the internal consistency of the items. Both, ECN and ESN, showed a good reliability (r= 0.77, p< 0.0001 and r= 0.76, p< 0.0001, respectively). ESN showed a good internal consistency (alpha= 0.74). The diagnosis of DPN, defined as the combination of the two scores (ECN+ESN) also showed a good reliability (r= 0.63, p< 0.0001). The Portuguese versions of the ESN and the ECN seem to be adequate for the diagnosis of DPN in this population.

OCT is a new method that can help the evaluation of ME in diabetic patients. It can be used not only to diagnose the lesion, but also to follow up the patients during treatment. High levels of haemoglobin A1c might be associated with the presence of ME. Diabetic complications (nephropathy and neuropathy) are associated with retinopathy but not with macular edema.

The objective of the present study was to establish the frequency of psychiatric comorbidity in a sample of diabetic patients with symmetric distal polyneuropathy (SDPN). Sixty-five patients with type 2 diabetes mellitus were selected consecutively to participate in the study at Instituto Estadual de Diabetes e Endocrinologia. All patients were submitted to a complete clinical and psychiatric evaluation, including the Portuguese version of the structured clinical interview for DSM-IV, the Beck Depression Inventory, the Neuropathy Symptom Score, and Neuropathy Disability Score. SDPN was identified in 22 subjects (33.8%). Patients with and without SDPN did not differ significantly regarding sociodemographic characteristics. However, a trend toward a worse glycemic control was found in patients with SDPN in comparison to patients without SDPN (HbA 1c = 8.43 ± 1.97 vs 7.48 ± 1.95; P = 0.08). Patients with SDPN exhibited axis I psychiatric disorders significantly more often than those without SDPN (especially anxiety disorders, in general (81.8 vs 60.0%; P = 0.01), and major depression -current episode, in particular (18.2 vs 7.7%; P = 0.04)). The severity of the depressive symptoms correlated positively with the severity of SDPN symptoms (r = 0.38; P = 0.006), but not with the severity of SDPN signs (r = 0.07; P = 0.56). In conclusion, the presence of SDPN seems to be associated with a trend toward glycemic control. The diagnosis of SDPN in diabetic subjects seems also to be associated with relevant psychiatric comorbidity, including anxiety and current mood disorders.
