Glycemic Control, Complications, and Death in Older Diabetic Patients: The Diabetes and Aging Study
OBJECTIVE—To identify the range of glycemic levels associated with the lowest rates of complications and mortality in older diabetic patients. RESEARCH DESIGN AND METHODS—We conducted a retrospective cohort study (2004–2008) of 71,092 patients with type 2 diabetes, aged 11.0%). Mortality had a U-shaped relationship with A1C. Compared with the risk with A1C,6.0%, mortality risk was lower for A1C levels between 6.0 and 9.0 % (e.g., 0.83 [0.76–0.90] for A1C 7.0–7.9%) and higher at A1C8.0%. Patterns generally were consistent across age-groups (60–69, 70–79, and $80 years). CONCLUSIONS—Observed relationships between A1C and combined end points suppor
Hypoglycemia is More Common Among Type 2 Diabetes Patients with Limited Health Literacy: The Diabetes Study of Northern California (DISTANCE)
Little is known about the frequency of significant hypoglycemic events in actual practice. Limited health literacy (HL) is common among patients with type 2 diabetes, may impede diabetes self-management, and thus HL could increase the risk of hypoglycemia.
To determine the proportion of ambulatory, pharmacologically-treated patients with type 2 diabetes reporting ≥1 significant hypoglycemic events in the prior 12 months, and evaluate whether HL is associated with hypoglycemia.
Cross-sectional analysis in an observational cohort, the Diabetes Study of Northern California (DISTANCE).
The subjects comprised 14,357 adults with pharmacologically-treated, type 2 diabetes who are seen at Kaiser Permanente Northern California (KPNC), a non-profit, integrated health care delivery system.
Patient-reported frequency of significant hypoglycemia (losing consciousness or requiring outside assistance); patient-reported health literacy.
At least one significant hypoglycemic episode in the prior 12 months was reported by 11% of patients, with the highest risk for those on insulin (59%). Patients commonly reported limited health literacy: 53% reported problems learning about health, 40% needed help reading health materials, and 32% were not confident filling out medical forms by themselves. After adjustment, problems learning (OR 1.4, CI 1.1-1.7), needing help reading (OR 1.3, CI 1.1-1.6), and lack of confidence with forms (OR 1.3, CI 1.1-1.6) were independently associated with significant hypoglycemia.
Significant hypoglycemia was a frequent complication in this cohort of type 2 diabetes patients using anti-hyperglycemic therapies; those reporting limited HL were especially vulnerable. Efforts to reduce hypoglycemia and promote patient safety may require self-management support that is appropriate for those with limited HL, and consider more vigilant surveillance, conservative glycemic targets or avoidance of the most hypoglycemia-inducing medications
Hormone replacement therapy is associated with better glycemic control in women with type 2 diabetes
WSTĘP. U kobiet chorych na cukrzycę zmiany towarzyszące menopauzie mogą
prowadzić do dalszego pogorszenia kontroli glikemii. Mało jest danych dotyczących
wpływu hormonalnej terapii zastępczej (HTZ) na metabolizm glukozy w cukrzycy.
Celem badania była ocena zmian stężenia HbA1c u kobiet chorych na cukrzycę typu
2, stosujących HTZ.
MATERIAŁ I METODY. W grupie 15 435 kobiet chorych na cukrzycę typu 2, należących
do organizacji chorych na cukrzycę, oceniano HTZ i HbA1c na podstawie zapisów
komputerowych w laboratorium oraz w rejestrach farmaceutycznych funkcjonujących
w ramach jednego programu zdrowotnego. Zestawiono również dane socjodemograficzne
oraz kliniczne.
WYNIKI. Średni wiek badanych wynosił 64,7 roku (SD ± 8,7). Grupa badana
obejmowała 55% kobiet rasy białej i 14% kobiet rasy czarnej pochodzenia innego
niż hiszpańskie, 12% kobiet pochodzenia hiszpańskiego, 11% Azjatek, 4% z innych
grup etnicznych i 4% z brakiem danych o pochodzeniu etnicznym. Stosowanie HTZ
wykazano u 25% kobiet. Stężenie HbA1c było istotnie niższe u kobiet aktualnie
stosujących HTZ niż u kobiet niestosujących HTZ (średnia skorygowana względem
wieku ± SE: 7,9 ± 0,03 vs. 8,5 ± 0,02, p = 0,0001). Nie stwierdzono różnic pomiędzy
kobietami stosującymi estrogeny w monoterapii i w połączeniu z progestagenami.
W modelu równania szacunku uogólnionego (Generalized Estimating Equation model),
uwzględniającego przypisanie pacjenta do lekarza i zależność względem wieku, pochodzenia
etnicznego, wykształcenia, nadwagi, leczenia hipoglikemizującego, czasu trwania
cukrzycy, samodzielnego monitorowania glikemii oraz aktywności fizycznej, HTZ
pozostawała znamiennym i niezależnym elementem związanym z niższą wartością HbA1c
(p = 0,0001).
WNIOSKI. Hormonalna terapia zastępcza jest w niezależny sposób powiązana
z obniżonym stężeniem HbA1c. Konieczne jest przeprowadzenie badania klinicznego
określającego możliwości poprawy kontroli glikemii poprzez stosowanie HTZ u kobiet
chorych na cukrzycę.OBJECTIVE. In women with diabetes, the changes
that accompany menopause may further diminish
glycemic control. Little is known about how hormone
replacement therapy (HRT) affects glucose metabolism
in diabetes. The aim of this study was to examine
whether HbA1c levels varied by current HRT
among women with type 2 diabetes.
MATERIAL AND METHODS. In a cohort of 15,435 women
with type 2 diabetes who were members of
a health maintenance organization, HbA1c and HRT
were assessed by reviewing records in the health
plan’s computerized laboratory and pharmacy systems. Sociodemographic and clinical information
were collected by survey.
RESULTS. The mean age was 64.7 years (SD ± 8.7).
The study cohort comprised 55% non-Hispanic whites,
14% non-Hispanic blacks, 12% Hispanics, 11%
Asians, 4% ”other” ethnic groups, and 4% with missing
ethnicity data. Current HRT was observed in 25%
of women. HbA1c levels were significantly lower in
women currently using HRT than in women not using
HRT (age-adjusted mean ± SE: 7.9 ± 0.03 vs. 8.5 ±
± 0.02, respectively, P = 0.0001). No differences in
HbA1c level were observed between women using
unopposed estrogens and women using opposed
estrogens. In a Generalized Estimating Equation
model, which took into account patient clustering
within physician and adjusted for age, ethnicity,
education, obesity, hypoglycemic therapy, diabetes
duration, self-monitoring of blood glucose, and exercise,
HRT remained significantly and independently
associated with decreased HbA1c levels (P = 0.0001).
CONCLUSIONS. HRT was independently associated
with decreased HbA1c level. Clinical trials will be necessary
to understand whether HRT may improve
glycemic control in women with diabetes

Metabolic Syndrome Predicts New Onset of Chronic Kidney Disease in 5,829 Patients With Type 2 Diabetes: A 5-year prospective analysis of the Hong Kong Diabetes Registry
OBJECTIVE—Type 2 diabetes is the leading cause of end-stage renal disease worldwide. Aside from hyperglycemia and hypertension, other metabolic factors may determine renal outcome. We examined risk associations of metabolic syndrome with new onset of chronic kidney disease (CKD) in 5,829 Chinese patients with type 2 diabetes enrolled between 1995 and 2005
Treating 4,000 diabetic patients in Cambodia, a high-prevalence but resource-limited setting: a 5-year study
BACKGROUND: Despite the worldwide increasing burden of diabetes, there has been no corresponding scale-up of treatment in developing countries and limited evidence of program effectiveness. In 2002, in collaboration with the Ministry of Health of Cambodia, Médecins Sans Frontières initiated an outpatient program of subsidized diabetic care in two hospital-based chronic disease clinics in rural settings. We aimed to describe the outcomes of newly and previously diagnosed diabetic patients enrolled from 2002 to 2008. METHODS: We calculated the mean and proportion of patients who met the recommended treatment targets, and the drop from baseline values for random blood glucose (RBG), hemoglobin A1c (HbA1c), blood pressure (BP), and body mass index (BMI) at regular intervals. Analysis was restricted to patients not lost to follow-up. We used the t test to compare baseline and subsequent paired values. RESULTS: Of 4404 patients enrolled, 2,872 (65%) were still in care at the time of the study, 24 (0.5%) had died, and 1,508 (34%) were lost to follow-up. Median age was 53 years, 2,905 (66%) were female and 4,350 (99%) had type 2 diabetes. Median (interquartile range (IQR)) follow-up was 20 months (5 to 39.5 months). A total of 24% (51/210) of patients had a HbA1c concentration of <7% and 35% (709/1,995) had a RBG <145 mg/dl within 1 year. There was a significant drop of 109 mg/dl (95% confidence interval (CI) 103.1 to 114.3) in mean RBG (P < 0.001) and a drop of 2.7% (95% CI 2.3 to 3.0) in mean HbA1c (P < 0.001) between baseline and month 6. In all, 45% (327/723) and 62% (373/605) of patients with systolic or diastolic hypertension at baseline, respectively, reached = 130/80 mm Hg within 1 year. There was a drop of 13.5 mm Hg (95% CI 12.1 to 14.9) in mean systolic blood pressure (SBP) (P < 0.001), and a drop of 11.7 mm Hg (95% CI 10.8 to 12.6) in mean diastolic blood pressure (DBP) (P < 0.001) between baseline and month 6. Only 22% (90/401) patients with obesity at baseline lowered their BMI <27.5 kg/m2 after 1 year. Factors associated with loss to follow-up were male sex, age >60 years, living outside the province, normal BMI on admission, high RBG on last visit, and coming late for the last consultation. CONCLUSION: Significant and clinically important improvements in glycemia and BP were observed, but a relatively low proportion of diabetic patients reached treatment targets. These results and the high loss to follow-up rate highlight the challenges of delivering diabetic care in rural, resource-limited settings
Oral bisphosphonate compliance and persistence: a matter of choice?
Compliance to oral bisphosphonates is suboptimal, with negative consequences of increased healthcare utilization and less effective fracture risk reduction. Extending dose interval increased adherence only moderately. We used literature derived from multiple chronic conditions to examine the problem of noncompliance with osteoporosis medication. We reviewed the literature on adherence to osteoporosis medication as well as that across multiple chronic conditions to understand what is known about the cause of the poor adherence. Poor compliance to oral medications is due mostly, not to forgetfulness, but to deliberate choice. Gender differences and style of healthcare management also play a role. Preliminary data suggest psychobehavioral interventions may help to improve motivation. We need to understand better reasons for poor compliance before effective interventions can be developed. Forgetfulness is only a small part of poor compliance. Patient preferences must be considered in medication decision making
The prevalence of diabetes and prediabetes in the adult population of Jeddah, Saudi Arabia- a community-based survey
BACKGROUND:
Type 2 (T2DM) is believed to be common in Saudi Arabia, but data are limited. In this population survey, we determined the prevalence of T2DM and prediabetes.
MATERIALS AND METHODS:
A representative sample among residents aged ≥ 18 years of the city of Jeddah was obtained comprising both Saudi and non-Saudi families (N = 1420). Data on dietary, clinical and socio-demographic characteristics were collected and anthropometric measurements taken. Fasting plasma glucose and glycated hemoglobin (HbA1c) were used to diagnose diabetes and prediabetes employing American Diabetes Association criteria. Multiple logistic regression analysis was used to identify factors associated with T2DM.
RESULTS:
Age and sex standardized prevalence of prediabetes was 9.0% (95% CI 7.5-10.5); 9.4% (7.1-11.8) in men and 8.6% (6.6-10.6) in women. For DM it was 12.1% (10.7-13.5); 12.9% (10.7-13.5) in men and 11.4% (9.5-13.3) in women. The prevalence based on World Population as standard was 18.3% for DM and 11.9% for prediabetes. The prevalence of DM and prediabetes increased with age. Of people aged ≥50 years 46% of men and 44% of women had DM. Prediabetes and DM were associated with various measures of adiposity. DM was also associated with and family history of dyslipidemia in women, cardiovascular disease in men, and with hypertension, dyslipidemia and family history of diabetes in both sexes.
DISCUSSION:
Age was the strongest predictor of DM and prediabetes followed by obesity. Of people aged 50 years or over almost half had DM and another 10-15% had prediabetes leaving only a small proportion of people in this age group with normoglycemia. Since we did not use an oral glucose tolerance test the true prevalence of DM and prediabetes is thus likely to be even higher than reported here. These results demonstrate the urgent need to develop primary prevention strategies for type 2 diabetes in Saudi Arabia
