Insulin lispro low mixture twice daily vs basal insulin glargine once daily and prandial insulin lispro once daily as insulin intensification strategies in patients with type 2 diabetes: Latin American subpopulation analysis of a randomized trial.

BACKGROUND: This post hoc analysis examined the efficacy and safety of twice-daily insulin lispro low mixture (LM25) and once-daily basal insulin glargine plus once-daily prandial insulin lispro (IGL) in a Latin American subpopulation with type 2 diabetes mellitus (T2DM). METHODS: A phase 4, randomized, open-label, parallel-arm trial included participants aged 18-75 years with T2DM taking once-daily insulin glargine and stable doses of metformin and/or pioglitazone with glycated hemoglobin (HbA1c) 7.5-10.5 % and fasting plasma glucose ≤121 mg/dL. Participants were randomized 1:1 to receive their stable dose of metformin and/or pioglitazone plus twice-daily LM25 or IGL for 24 weeks. The primary efficacy outcome was change in HbA1c after 24 weeks of treatment. Results from participants in Argentina, Brazil, and Mexico are presented here. RESULTS: 162 participants (80 LM25; 82 IGL) with mean ± standard deviation (SD) age = 57.3 ± 9.0 years and body mass index = 31.3 ± 5.2 kg/m(2) were included. Mean ± SD change in HbA1c from baseline to week 24 was -1.5 ± 1.0 % (LM25) and -1.1 ± 1.2 % (IGL). At week 24, 35.1 % (LM25) and 31.6 % (IGL) of participants achieved HbA1c <7.0 %. Mean ± SD weight gain from baseline to week 24 was 2.4 ± 2.9 kg in the LM25 group and 1.0 ± 3.1 kg in the IGL group. The mean ± SD rates of total hypoglycemia per year were 18.9 ± 27.3 (LM25) and 21.6 ± 31.1 (IGL). Rates of treatment-emergent adverse events were 46 % (LM25) and 39 % (IGL). CONCLUSIONS: Our results suggest that both LM25 and IGL are viable treatment options for insulin intensification in Latin American patients with T2DM with suboptimal glycemic control on basal insulin glargine. The safety and tolerability profiles of LM25 and IGL are consistent between this Latin American population and the global trial-level population. Trial registration NCT01175824.

Challenges associated with insulin therapy progression among patients with type 2 diabetes: Latin American MOSAIc study baseline data.

BACKGROUND: Poor glycemic control in patients with type 2 diabetes is commonly recorded worldwide; Latin America (LA) is not an exception. Barriers to intensifying insulin therapy and which barriers are most likely to negatively impact outcomes are not completely known. The objective was to identify barriers to insulin progression in individuals with type 2 diabetes mellitus (T2DM) in LA countries (Mexico, Brazil, and Argentina). METHODS: MOSAIc is a multinational, non-interventional, prospective, observational study aiming to identify the patient-, physician-, and healthcare-based factors affecting insulin intensification. Eligible patients were ≥18 years, had T2DM, and were treated with insulin for ≥3 months with/without oral antidiabetic drugs (OADs). Demographic, clinical, and psychosocial data were collected at baseline and regular intervals during the 24-month follow-up period. This paper however, focuses on baseline data analysis. The association between glycated hemoglobin (HbA1c) and selected covariates was assessed. RESULTS: A trend toward a higher level of HbA1c was observed in the LA versus non-LA population (8.40 ± 2.79 versus 8.18 ± 2.28; p ≤ 0.069). Significant differences were observed in clinical parameters, treatment patterns, and patient-reported outcomes in LA compared with the rest of the cohorts and between Mexico, Brazil, and Argentina. Higher number of insulin injections and lower number of OADs were used, whereas a lower level of knowledge and a higher level of diabetes-related distress were reported in LA. Covariates associated with HbA1c levels included age (-0.0129; p < 0.0001), number of OADs (0.0835; p = 0.0264), higher education level (-0.2261; p = 0.0101), healthy diet (-0.0555; p = 0.0083), self-monitoring blood glucose (-0.0512; p = 0.0033), hurried communication style in the process of care (0.1295; p = 0.0208), number of insulin injections (0.1616; p = 0.0088), adherence (-0.1939; p ≤ 0.0104), and not filling insulin prescription due to associated cost (0.2651; p = 0.0198). CONCLUSION: MOSAIc baseline data showed that insulin intensification in LA is not optimal and identified several conditions that significantly affect attaining appropriate HbA1c values. Tailored public health strategies, including education, should be developed to overcome such barriers. Trial Registration NCT01400971.

[Olfactory groove schwannoma: case report]. / Schwannoma da goteira olfatória: relato de caso.

Intracranial schwannoma not related to cranial nerves are unusual and rarely found in the subfrontal region. We report a case of olfactory groove schwannoma in a 27-year-old male, who presented with anosmia and headache initiated one year ago. At admission, bilateral papilledema was noted with absense of motor deficits or cranial nerves abnormalities. Cranial computed tomography (CT) revealed a bifrontal multicystic isodense enhancing mass lesion causing a frontal ventricular horn compression. Radiological features resembled that of a cystic olfactory groove meningioma. Decompressive bifrontal craniotomy was done. One month later, CT demonstrated a homogeneously contrast-enhancing mass in the olfactory groove region who extended into the left nasal cavity. Magnetic resonance imaging did not add more informations. A second surgical procedure was done through a nasoethmoidal approach with incomplete resection of the lesion. The complete tumor resection was only possible in a third surgery through another bifrontal approach. The hystopathological diagnosis of schwannoma was performed by conventional methods and confirmed by immunohistoquemical staining for S-100 protein. The rarity of this tumor and his clinical, radiological and histological aspects justify this publication.
