Vitamin-D as an adjunct drug in DM to prevenbt atheroma.


How many of us estimate about  Postprandial    lipemia in DM::: In  diabetes  this lipaemia is an  treatable risk factor for subsequent   cardiovascular    disease .
Men & women suffering from DM die of Coronary Heart diseases and or athermanous Renal diseases (CKD). We the gynaecologits should not view that DM as just an another non communicable    disease    characterized by elevated blood glucose only , but time has come when  our Face Bok members and friends in this page  should also realize and believe that if we allow formation of atheroma  it may be treated as an act of negligence Atheroma & Diabetic dyslipidaemia    which is forerunner of serious vascular   disease   with poor prognosis.  What is more important is Lipid    abnormalities   which  play an important part in raising the risk of cardiovascular   diseases   in diabetic subjects   . Among    the metabolic abnormalities    that commonly accompany diabetes are disturbances   in the A)  production   and clearance of plasma lipoprotein ,  B)  increased   triglycerides and postprandial    lipemia. This    pattern is most frequently seen  in type  2 diabetes    and may be treatable risk factor for subsequent   cardiovascular    disease . In    addition the National cholesterol Education Program     Expert Panel  on Detection  Evaluation and Treatment  of High Blood  cholesterol  in Adults   proposes that  persons with  diabetes  and without coronary   heart   disease are  to be treated   to the level  of CHD risk equivalents . Consequently      patients with type 2  diabetes   should be  treated aggressively  to reduce   the risk of CHD  .

What are the adjunctive therapies that are safe    efficacious and cost effective in obese diabetics ?? -. People often ask diabetologists can U change the drug?? Now we have to consider what pharmacological   medications are   currently available   to treat   patients with type 2 diabetes with an aim to reduce associated possible heart diseases?? Many diabetic patients   do not achieve the current recommended   goal of HbA1 < 7% especially   those who are    obese . They feel depressed as in spite of stringent diet , exercise  &    drugs many an  Obese   patients are likely to be the most    insulin resistant   and are the   most difficult   to control   with currently  available standard   therapies . Thus   there is   a need to identify     and evaluate   adjunctive therapies that  are  safe    efficacious and cost   effective.
Conventional   and alternative therapies  for type 2 diabetes
. In addition  to the conventional   therapy supplementation with  additional key nutrients and vitamin  has been shown   to improve blood   sugar levels   and prevent    or ameliorate many   major    complications    in diabetes . Some of the minerals   and vitamins   that can be   useful  as adjunctive   treatments  in diabetes     include the  following Evidenced data indicate  that antioxidant  vitamins   such as vitamins C and E flavonoids   vitamin D conjugated   linoleic  acid  omega  3 fatty acids ,  minerals such as  chromium   and magnesium alpha lipioic acid phytoestrogens and   dietary fibers  have been  shown  to target the pathogenesis of  diabetes   mellitus  metabolic    syndrome and their   complications and favorably modulate   a number of   biochemical    and clinical   endpoints.

The drugs which have claimed in last two decades as an adjunct drug in established DM to minimize atheroma and delay coronary attack and or CKD(chr Kidney diseases).

Vitamin D and type   2 diabetes   link
The relationship   between  type  1 diabetes  mellitus    and vitamin D deficiency   has been extensively   reported . Animal   and human models   have shown  the vitamin D treatment   has been shown to   improve and even    prevent type  1 diabetes   mellitus     . However    recent studies   throw focus   on the association   between    vitamin D  and type 2 diabetes . Published  data report    that vitamin D deficiency   alters insulin   synthesis and  secretion in both  humans and animal   models Vitamin D deficiency  may predispose     to glucose    intolerance  . altered insulin secretion  and type 2 diabetes  mellitus.
Researchers  suggest a role for vitamin D in the pathogenesis   of type 2 diabetes   mellitus   as vitamin d  replenishment   improves   glycaemia   and insulin secretion   in patients   with Type 2  diabetes   with established  hypo vitaminosis D .
Vitamin D may be obtained  directly from the diet   or by means   of the sunlight   induced  photochemical  conversion of 7 dehydrocholesterol to pre vitamin D . Pre vitamin d  is thermodynamically   unstable  and undergoes  thermally induced  conversion  to vitamin D To become biologically  active Vitamin D  must be hydroxylated   twice in the body . The  first  hydroxylation  process takes place  in the liver and forms 25 hydroxy vitamin D 25 D. The second hydroxylation   step   occurs predominantly  in the kidney which     produces   the final  active metabolite of vitamin D -1,25d . This   formed   1,25  d is released   into the circulation where  is binds   to vitamin d binding  protein  until it reaches its target   tissue  by means  of the vitamin D  receptors   . The  entire   process   described .
The pancreas  possesses VDR  and 1-a hydroxylase  and thus   has the vitamin D machinery   for circulating  25 D  to be converted  to 1,25D to work   as a  paracrine   or autocrine hormone. The mechanism of action  of vitamin D in type 2  diabetes  is though to be mediated not only through  regulation  of plasma   calcium  levels  which  regulate  insulin  synthesis and secretion   but also  through  a  direct   action on pancreatic    B cell   function.
Thus  substantial   evidence   supports   a relationship   between   vitamin D status and insulin   sensitivity   however the underlying  mechanisms require  further   exploration.
The action of vitamin D    in type 2  diabetes  is thought  to be mediated   not only through  regulation   of plasma   calcium levels  which regulate insulin   synthesis    and secretion   but also   through  a direct   action on pancreatic   B cell   function.
