Association between sleep disturbances, fear of hypoglycemia and psychological well-being in adults with type 1 diabetes mellitus, data from cross-sectional VARDIA study.

AIM: To assess the relationship between sleep quality, fear of hypoglycemia, glycemic variability and psychological well-being in type 1 diabetes mellitus. METHODS: Our data were provided by the VARDIA Study, a multicentric cross-sectional study conducted between June and December 2015. Sleep characteristics were assessed by the Pittsburgh Sleep Quality Index (PSQI). Fear of hypoglycemia and psychological well-being were measured with the Hypoglycemia Fear Survey version II (HFS-II) and the Hospital Anxiety and Depression Scale (HADS), respectively. Glycemic variability (GV) was determined using the CV of three 7-point self-monitoring blood glucose profiles and the mean amplitude of glycemic excursion (MAGE). RESULTS: 315 patients were eligible for PSQI questionnaire analysis: 54% women, mean age 47 ± 15, mean diabetes duration of 24 ± 13 years, HbA1c of 7.6 ± 0.9% (60 ± 7,5mmol/mol). Average PSQI score was 6.0 ± 3.3 and 59.8% of the patients had a PSQI score > 5. HFS-II score and HADS were significantly higher among "poor" sleepers (p < 0.0001) and PSQI score was positively associated with HADS (ß = 0.22; 95% CI = 0.08;0.35). GV evaluated by CV or MAGE did not differ between "poor" and "good" sleepers (p = 0.28 and 0.54, respectively). CONCLUSIONS: Adult patients with type 1 diabetes have sleep disturbances which correlate with psychological well-being. This study suggests that psychological management can be a target to improve sleep quality in adults with type 1 diabetes mellitus.

No association between fear of hypoglycemia and blood glucose variability in type 1 diabetes: The cross-sectional VARDIA study.

AIMS: In type 1 diabetes (T1D), treatment efficacy is limited by the unpredictability of blood glucose results and glycemic variability (GV). Fear of Hypoglycemia (FOH) remains a major brake for insulin treatment optimization. We aimed to assess the association of GV with FOH in participants with T1D in an observational cross-sectional study performed in 9 French Diabetes Centres (NCT02790060). METHODS: Participants were T1D for ≥5 years, aged 18-75 years, on stable insulin therapy for ≥3 months. The coefficient of variation (CV) of blood glucose and mean amplitude of glycemic excursions (MAGE) were used to assess GV from 7-point self-monitoring of blood glucose (SMBG). FOH was assessed using the validated French version of the Hypoglycemia Fear Survey-II (HFS-II) questionnaire. RESULTS: Among a total of 570 recruited participants, 298 were suitable for analysis: 46% women, 58% on continuous subcutaneous insulin infusion [CSII], mean age 49 ±â€¯16 years, HbA1c 7.5 ±â€¯0.9%, HFS-II score 67 ±â€¯18 and 12% with recent history of severe hypoglycemia during the previous 6 months, mean CV 39.8 ±â€¯9.7% and MAGE 119 ±â€¯42 mg/dL. CV and MAGE did not significantly correlate with HFS-II score (R = -0.05;P = 0.457 and R = 0.08;P = 0.170). Participants with severe hypoglycemia in the previous 6 months had higher HFS scores. Participants with higher HFS scores presented more hypoglycemias during follow-up. CONCLUSIONS: FOH as determined using the HFS-II questionnaire was not associated with 7-point SMBG variability in participants with T1D, but was associated with a positive history of severe hypoglycemia. Higher FOH was associated with higher frequency of hypoglycemia during follow-up.

Systemic vasculitis with lymphocytic temporal arteritis and Toxocara canis infection.

Vasculitis associated with helminthic infection is rare. We report a case of systemic negative antineutrophil cytoplasmic antibodies vasculitis associated with Toxocara canis infection documented by enzyme-linked immunosorbent assay and Western blot analysis. This case report is unusual because of lymphocytic temporal arteritis and renal involvement. The spontaneous remission of systemic vasculitis without use of steroids or immunosuppressive agents favors a close relationship between vasculitis and the parasite that is more than a coincidental association. To our knowledge, this is the first observation of temporal vasculitis associated with helminthic infection, extending the clinical spectrum of visceral larva migrans.

Aortic involvement in recent-onset giant cell (temporal) arteritis: a case-control prospective study using helical aortic computed tomodensitometric scan.

OBJECTIVE: The prevalence of the involvement of large vessels in giant cell arteritis (GCA) is 3-13%. Aortitis is the most serious complication of GCA. Computed tomodensitometric (CT) scan allows analysis of both the aortic wall and endoluminal part of the aorta. Therefore, we conducted a study using CT scan to analyze aortic abnormalities in patients with recent-onset GCA. METHODS: This prospective controlled study compared patients with biopsy-proven GCA with a matched control group based on sex, age, and cardiovascular risk factors. During the 4-week period following diagnosis of GCA, patients underwent an aortic CT scan. The aortic imaging results were blindly compared between both groups. RESULTS: From January 5, 1998 to January 11, 1999, 22 patients and 22 controls were screened by CT scan for aortic involvement. Thickening of the aortic wall was more frequent among patients than controls (45.4% versus 13.6%; P = 0.02). Aortic thickening (mean 3.3 mm) was located on the ascending part of the thoracic aorta in 22.7% of the patients, with no evidence of thickening in the controls (P = 0.05). Thickening of the abdominal aortic wall was noted in 27.3% of the patients and none of the controls (P = 0.02). CONCLUSION: This study suggests that inflammatory aortic thickening, detected by CT scan, occurs frequently at the time of diagnosis of GCA, and that this condition predominantly occurs on the ascending part of the aorta.

[Hypersensitivity to celecoxib]. / Syndrome d'hypersensibilité au célécoxib.

Celecoxib is a non-steroidal anti-inflammatory drug (NSAID) which acts via specific inhibition of cyclooxygenase-2 (synthesis of prostaglandins mediating pathological inflammation) but which preserves the homeostatic action of cyclooxygenase-1. The efficacy of celecoxib is similar to that of classical NSAIDs and its tolerance is comparable with that of placebo. We nevertheless observed one patient with hypersensitivity to celecoxib who developed fever, toxic skin reaction, and liver involvement.
