What is the diagnosis and plan of care for a patient with poorly controlled diabetes mellitus, hyperlipidemia, leukocytosis, and neutrophilia?

Diagnosis and Management Plan

Primary Diagnoses

This patient has poorly controlled type 2 diabetes mellitus (A1c 9.1%), hyperlipidemia with elevated cardiovascular risk, and leukocytosis with neutrophilia requiring infection workup. 1, 2

Diabetes Mellitus Type 2

• A1c of 9.1% (glucose 188 mg/dL) confirms poorly controlled diabetes, well above the target of <7% for most patients 3
• The elevated glucose and A1c indicate urgent need for glycemic optimization to prevent acute complications including dehydration, poor wound healing, and hyperglycemic hyperosmolar syndrome 3

Hyperlipidemia with High Cardiovascular Risk

• Total cholesterol 235 mg/dL, LDL 158 mg/dL (target <100 mg/dL), HDL 48 mg/dL (low), triglycerides 162 mg/dL, cholesterol/HDL ratio 4.9 1
• This lipid profile combined with diabetes creates very high cardiovascular risk requiring aggressive management 1, 2

Leukocytosis with Neutrophilia

• WBC 14.3 with neutrophils 10.4 suggests possible infection or inflammatory process 1
• Must evaluate for occult infection, particularly given diabetes increases infection risk and impairs wound healing 3

Immediate Management Plan

Step 1: Rule Out Infection

• Perform targeted history for fever, localizing symptoms (urinary, respiratory, skin/soft tissue), recent trauma, or wounds 3
• Physical examination focusing on: feet (ulcers, cellulitis), lungs (pneumonia), urogenital exam, skin integrity 3
• Order urinalysis with culture, chest X-ray if respiratory symptoms, wound cultures if skin breakdown present 3
• The leukocytosis must be explained before attributing it solely to hyperglycemia 1

Step 2: Initiate Diabetes Pharmacotherapy

Start metformin 500 mg twice daily with meals, titrating to 1000 mg twice daily over 2-4 weeks as tolerated. 2

• Metformin is first-line therapy for type 2 diabetes with established efficacy, safety, cardiovascular benefits, and low cost 3, 2
• Verify renal function is adequate (eGFR ≥30 mL/min/1.73 m²) before initiating 3
• If A1c remains >7% after 3 months on maximum tolerated metformin dose, add second agent with low hypoglycemia risk (DPP-4 inhibitor or GLP-1 agonist preferred over sulfonylureas in older adults) 3

Step 3: Aggressive Lipid Management

Initiate at least moderate-intensity statin therapy immediately given diabetes plus hyperlipidemia (very high cardiovascular risk). 1, 2

• Target LDL-C <100 mg/dL with ≥30-40% LDL reduction from baseline 1
• Atorvastatin 20-40 mg daily or rosuvastatin 10-20 mg daily are appropriate moderate-to-high intensity options 1
• Recheck lipid panel in 4-6 weeks to assess response and adjust dose 1

Step 4: Blood Pressure Assessment and Management

• Measure blood pressure at this visit and every subsequent diabetes visit 1
• If BP ≥130/80 mmHg, initiate ACE inhibitor or ARB as first-line therapy (provides dual benefit of BP control and renal protection in diabetes) 1, 2
• Target BP <130/80 mmHg per American Heart Association guidelines 1

Step 5: Aspirin for Primary Prevention

• Initiate aspirin 75-162 mg daily for primary cardiovascular prevention given diabetes with multiple cardiovascular risk factors (hyperlipidemia, likely 10-year CVD risk >10%) 1

Diabetes Self-Management Education

Lifestyle Modifications (Essential Component)

• Weight loss of at least 5% through caloric restriction if overweight/obese 2
• At least 150 minutes of moderate-intensity aerobic activity per week, distributed over ≥3 days with no more than 2 consecutive days without activity 1, 2
• Resistance training at least twice weekly 2
• Reduced saturated fat and cholesterol intake, increased dietary fiber, reduced sodium 1, 2

Self-Monitoring of Blood Glucose

• Teach SMBG focusing on fasting and 2-hour postprandial values 2
• Frequency depends on regimen complexity, but at minimum check fasting glucose several times weekly 3

Diabetes Education

• Provide diabetes self-management education at diagnosis covering: medication adherence, dietary modifications, exercise, foot care, sick-day management, hypoglycemia recognition 3
• Refer to diabetes educator or nutritionist experienced in medical nutrition therapy 3

Monitoring Schedule

Short-Term (First 3 Months)

• Recheck A1c every 3 months until target <7% achieved 1, 2
• Recheck lipid panel in 4-6 weeks after statin initiation 1
• Monitor renal function (creatinine, eGFR) and potassium within first 3 months of ACE inhibitor/ARB if initiated 1
• Follow up on infection workup results and treat appropriately 3

Long-Term (After Glycemic Control Achieved)

• A1c every 6 months once at goal 1, 2
• Annual lipid panel 1
• Annual urine albumin-creatinine ratio and eGFR for nephropathy screening 1
• Annual comprehensive foot examination with 10-g monofilament testing plus assessment of pedal pulses, skin integrity, and bony deformities 3
• Annual dilated retinal examination by ophthalmologist or optometrist 1
• Blood pressure at every routine diabetes visit 1

Critical Pitfalls to Avoid

Hypoglycemia Risk

• Avoid sulfonylureas or insulin as initial therapy given high hypoglycemia risk, especially if patient lives alone or has impaired awareness 3
• Metformin and DPP-4 inhibitors have minimal hypoglycemia risk 3

Overlooking Infection

• The leukocytosis with neutrophilia cannot be ignored—diabetes increases infection susceptibility and infections worsen glycemic control, creating a dangerous cycle 3
• Diabetic foot infections are particularly insidious and require aggressive management 3

Undertreatment of Cardiovascular Risk

• Greater reductions in morbidity and mortality result from controlling cardiovascular risk factors (BP, lipids) than from tight glycemic control alone 3
• This patient requires statin therapy regardless of glycemic control status 1

Metformin Contraindications

• Verify no significant heart failure, renal insufficiency (eGFR <30), or hepatic dysfunction before prescribing 3
• Temporarily discontinue during acute illness if risk of lactic acidosis increases 3
