Diagnosis• Rt lower lobe pneumonia in a case of Uncontrolled diabetes,
uncontrolled dyslipidemia, hypertension, and obesity
Management
• Inj Amoxy-clav + IV clarithro • What should be the choice of therapy for controlling DM in this
case scenario?
Diagnosis and Management Plan
Many good drugs are available but they have some limitation particularly – in CKD,derranged LFT, obesity or lead to weight gain
Choose A Safe drug which will help in preservation of organs in a long run which is a ultimate goal of ours
Limitations with current oral glucose-lowering agentsDo newer agents address these limitations??

Dapagliflozin as add-on to insulin (± OADs): Significant reductions in HbA1c sustained over 2 years1
Dapagliflozin is not indicated for the management of obesity.3 Weight change was a secondary endpoint in clinical trials.3,4
A multicentre, randomised, double-blind, placebo-controlled, parallel-group, 24-week study in patients with Type 2 diabetes with inadequate glycaemic control (HbA1c 7.5–10.5%) on a stable dose of insulin ± up to two OADs. Primary endpoint: HbA1c reduction at 24 weeks.1 Data are adjusted mean change from baseline estimated from a mixed model.1. Wilding JP, et al. Diabetes Obes Metab 2014;16:124–36; 2.

Dapagliflozin also offers…
additional benefit of weight loss without the
need for increased insulin
dosing
At 24 weeks, dapagliflozin was associated with HbA1c reductions of –0.96% versus –0.39% with placebo (p<0.001)2

The reduction in interglomerular pressure induced by SGLT2 inhibitors may provide benefits to patients with CKD
Dapagliflozin demonstrates potential nephroprotective effects in combination with renin-angiotensin system blockade, as significant reductions in UACR over 50 weeks in patients with T2D and moderate renal function were observed

PossibleNephroprotection
Patient Populations where I would prefer other OADs
• Type 1 diabetes.
• Patients >75 years
• Patients with eGFR <45mL/min
• Pregnancy and Nursing woman
• Patients with Recurrent UTI / GUI
• Patients with history of volume depletion, dehydration

• Due to increasing weight gain and hypoglycemic episodes, Dapagliflozin was added while Insulin dose was reduced to 55 IU (25% reduction in dose )*. Metformin was continued.
• Lifestyle intervention program which focused on low-fat diet and regular exercise was devised and the patient was counseled to adopt the same.
• Dosage of statins was increased to control lipid parameters.
• Self-monitoring of diabetes was encouraged to achieve better results and regular monitoring of blood pressure was advised.
Management
At 6 months
• Patient’s weight had reduced further 1.5 kg and her lipid parameters were approaching normal levels.• HbA1c 7.5%, not reporting episodes of hypoglycemia
Follow-Up
At 3 months:
• Weight loss of about 2.5 kg• HbA1c: 7.9% ; FBS:128 mg/dL; PPBS: 208 mg/dL• SBP and DBP decreased by 4mmHg and 2mmHg respectively.• Lipid parameters improved.• Advised to continue with same medications with no need to increase Insulin dose• Lifestyle modifications reinforced

• SGLT2 inhibitors can be better choice
who has normal renal function (eGFR- >45) along with insulins or OHA in case of uncontrolled hyperglycemia in type 2 DM
