6. ADA/EASD Consensus Guidelines Treatment Algorithm, 2006
Diagnosis
Step 1
Lifestyle intervention + Metformin
HbA1c  7%
Step 2
Add basal insulin
(Most effective)
Add sulfonylurea
(Least expensive)
Add glitazone
(No hypoglycemia)
Additional medications: insulin, sulfonylureas or TZDs, on the top of metformin
Nathan DM, et al. Diabetes Care 2006;29:8.

7. ADA/EASD guidelines recommend use of basal insulin as early as the second step in type 2 diabetes management
Tier 1: well-validated core therapies
Lifestyle + Metformin
plus Basal insulin
Lifestyle + Metformin

The ADA and EASD issued this consensus statement in 2008 as an algorithm for the management of hyperglycemia in patients with T2D.
T2D is a progressive disease. Therefore, when required, treatment can be intensified by adding a further agent to the existing treatment regimen. The guidelines state that the goal of treatment should be to reduce HbA1c as close to the healthy range as possible (<6.0%) or, at the very least, to <7.0%. When lifestyle modification and treatment with metformin fails to achieve HbA1c levels <7.0%, the addition of basal insulin should be considered (Step 2). An alternative option is the addition of basal insulin at step 3 instead of a third OHA. Initiation orintensification of insulin is the preferred option at this stage, because the addition of a third OHA is no more effective than insulin and is more costly. Intensification of insulin therapy should be achieved by adding prandial insulin injections at selected meals to decrease postprandial BG levels. The ADA/EASD recognize that the HbA1c target of 7.0% is not practical for some patients and recommend that the potential risks and benefits of intensified treatment are assessed for every patient.

9. New IDF guidelines 2011 in type 2 diabetes:
Two key changes :
A change in the HbA1c target to 7.0% (previously 6.5%)
Algorithm TT :effectiveness, harm, cost and global availability
Each step of the algorithm recommends a preferred therapy and also alternative therapies:
Metformin as first line therapy(unless contraindicated)
Sulfonylureas are the recommended second line
Third line therapy is either a third oral agent or insulin (basal or premixed)
Finally insulin should be used if the choice has been to use an oral agent as the third step, or intensification of insulin therapy if insulin had been chosen in the previous step.

10. Considerations for Fasting During Ramadan
Religious Considerations: imposition, obligation
Exemption of the sick

12. فتوى مجمع الفقه الإسلامي الدولي 2010
تم تصنيف المصابين بالسكري إلى اربع فئات :
الفئة الأولى: المصابين بالسكري ذوو الاحتمالات الكبيرة جدا للمضاعفات الخطيرة بصورة مؤكدة :
• حدوث هبوط السكر الشديد أو المتكرر أو الفقدان الحس بنقص السكر (خلال الأشهر الثلاثة التي تسبق رمضان) • حدوث الغيبوبة السكرية ) الحماض الكيتوني أو فرط التناضح) خلال الشهور الثلاثة التي تسبق رمضان • الأمراض الحادة الاخرى المرافقة للسكري • يمارسون مضطرين أعمالا بدنية شاقة • يجري لهم غسيل كلى
• اثناء الحمل

13. فتوى مجمع الفقه الإسلامي الدولي 2010
الفئة الثانية: احتمال كبير لحدوث مضاعفات نتيجة الصيام والتي يغلب على ظن الأطباء وقوعها وتتمثل بـ:
• ارتفاع السكر ( ملغ/دسل) و الخضاب السكري < 10%
• قصور كلوي
• اعتلال القلب والشرايين الكبيرة
• أمراض أخرى تضيف أخطاراً إضافية عليهم
• الذين يسكنون بمفردهم
• كبار السن المصابون بأمراض أخرى
• يتلقون علاجات تؤثر على العقل

14. فتوى مجمع الفقه الإسلامي الدولي 2010
حكم الفئتين الأولى والثانية:
فيتعين شرعاً على المريض ان يفطر ولا يجوز له الصيام، درءاً للضرر عن نفسه، لقوله تعالى: (وَلاَ تُلْقُواْ بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ) البقرة
كما يتعين على الطبيب المعالج ان يبين لهم خطورة الصيام عليهم، والاحتمالات الكبيرة لإصابتهم بمضاعفات قد تكون -في غالب الظن- خطيرة على صحتهم أو حياتهم

15. فتوى مجمع الفقه الإسلامي الدولي 2010
الفئة الثالثة: ذوو الاحتمالات المتوسطة للتعرض للمضاعفات نتيجة الصيام ويشمل ذلك المصابين بالسكري ذوي الحالات المستقرة والمسيطر عليها بالـ S.U.
الفئة الرابعة: ذوو الاحتمالات المنخفضة للتعرض للمضاعفات نتيجة الصيام ويشمل ذلك المصابين بالسكري ذوي الحالات المستقرة والمسيطر عليها بمجرد الحمية أو بتناول العلاجات METF.
حكم الفئتين الثالثة والرابعة:
لا يجوز لمرضى هاتين الفئتين الإفطار، لان المعطيات الطبية لا تشير إلى احتمال مضاعفات ضارة بصحتهم وحياتهم بل ان الكثير منهم قد يستفيد من الصيام. وعلى الطبيب الالتزام بهذا الحكم وان يقدر العلاج المناسب لكل حالة على حدة.

16. Considerations for Fasting During Ramadan
Religious Considerations:
Exemption of the sick
Medical Considerations:
Need to define which diabetic is sick enough to be at risk and should be advised not to fast

17. Duration of Fast There is variation in the number of days:
Depends on the moon sighting.
There is variation in the number Fasting hours:
Depends on the season.
There is variation in the Temperature:
Effect on total body fluid.

19. Change in blood glucose profile
Daily glucose profile during the month of Shawal
Patients were asked to test their blood sugar every two hours with a glucometer for one day during the month of Shawal as part of diet change study regardless of their diabetes management. There are three peaks for serum blood glucose following meals. The highest been following lunch and the lowest following breakfast with a mean daily glucose at 10.2 mmol/L.

20. Change in blood glucose with meal timing

Risk of hypoglycemia
The change in meal time will affect the glucose level through the day.
There will be a prolonged period of fasting with risk of hypoglycemia.
Sever hyperglycemia occur following the main meal ( ie: Eftar ).
Ramadan Diabetes Study ( unpublished data )

22. Biochemistry of Fasting
Carbohydrate metabolism
In normal subjects fasting will:
Decrease in serum glucose to mmol ( mg/dl ).
Gluconeogenesis by liver will stop further drop of blood glucose.
Insulin secretion will decrease but glucagon will increase.
In diabetic subjects fasting will:
Blood glucose fell within physiological limits if properly controled.
Drug induced hypoglycemia is the commonest complications.

36. II. Pre-Ramadan medical assessment and educational counseling

37. I. General considerations: Nutrition
The diet during Ramadan should not differ significantly from a healthy and balanced diet
It should aim at maintaining a constant body mass :
50–60% maintain their BMI
20–25% gain or lose weight (>3 kg)
Avoid the ingesting of large amounts of foods rich in carbohydrate and fat
Advise the ingestion of foods containing “complex” carbohydrates at the predawn meal
Advise Simple carbohydrates at the sunset meal
Fluid intake be increased during non fasting hours
Monira Al-Arouj,, Samir Assaad-Khalil,, John Buse, MDDiabetes Care August 2010 vol. 33 no

38. I. General considerations: Exercise:
Normal levels of physical activity may be maintained
Excessive physical activity may lead to higher risk of hypoglycemia and should be avoided particularly before the sunset meal
Tarawaih prayer should be considered a part of the daily exercise program
In some patients with poorly controlled type 1 diabetes, exercise may lead to extreme hyperglycemia.

39. I. General considerations; Breaking the fast
If hypoglycemia (blood glucose of <60 mg/dl)
If blood glucose reaches <70 mg/dl (3.9 mmol/l) in the first few hours after the start of the fast especially if insulin, sulfonylurea drugs, or meglitinide are taken at predawn fast
if blood glucose exceeds 300 mg/dl
Typical or atypical symptoms of hypoglycemia ?

40. III. Management of patients with type 1 DM
INSULIN THERAPY
It is unlikely that one injection of intermediate- or long-acting insulin administered before the evening meal would provide adequate insulin coverage for 24 h:
Less flexible ( fixe dose)
Hypoglycemic risk
Timing during Ramadan
Another option could be to use:
one daily injection of the long-acting insulin analog Glargine
or twice-daily injections of the insulin analog Detemir with premeal rapid-acting insulin analogs

41. IV. Management of patients with type 2 DM
DIET-CONTROLLED PATIENTS:
the risk associated with fasting is quite low
there is still a potential risk for occurrence of postprandial hyperglycemia after the predawn and sunset meals
combine this with a regular daily exercise program∼2 h after the sunset meal (Tarawih)
older age-group, often with hypertension and dyslipidemia, fluid restriction and dehydration may increase the risk of thrombotic

42. IV. Management of patients with type 2 DM
PATIENTS TREATED WITH ORAL AGENTS:
Metformin: two thirds of the total daily dose be administered immediately before the sunset meal
Glitazones no change
Sulfonylureas unsuitable for use during fasting because of the inherent risk of hypoglycemia utilized with caution Use of chlorpropamide is absolutely contraindicated(gliclazide MR or glimepiride) have been shown to be effective
Sulfonylureas Short-acting insulin secretagogues: repaglinide might be safer than use of

43. (similar to those with type 1 diabetes)
IV. Management of patients with type 2 DM
PATIENTS TREATED WITH INSULIN
(similar to those with type 1 diabetes)
Use of intermediate- or long-acting insulin preparations plus a short-acting, or premixed insulin administered before meals hypoglycemia is still a risk
Using one injection of a long-acting insulin analog, such as insulin Glargine
or two injections of NPH, Lente, Detemir insulin
The dosage of each injection should appropriately individualized
Very elderly patients may be at high risk

44. "Basal" Insulins: intermediate or long-acting insulins
Reproduce the basal insulin secretion Inhibition of hepatic glucose production Control of FBG

48. V. Pregnancy and fasting during Ramadan
controversy :
pregnant Muslim women are exempt from fasting
some with known diabetes (type 1, type 2, or gestational) insist on fasting during Ramadan
These women constitute a high-risk group, and their management requires intensive care
Women with pregestational or gestational diabetes should be strongly advised to not fast during Ramadan
if they insist on fasting: special attention should be given to their care
Pre-Ramadan evaluation of their medical condition is essential

49. VI. Management of hypertension and dyslipidemia
Dehydration, volume depletion
A tendency toward hypotension may occur with fasting
medications antihypertensive perspiration may need to be adjusted to prevent hypotension
Dyslipidemia should be checked during Ramadan
