Pathology Case Analysis: Chronic Kidney Disease and Diabetic Ketoacidosis Management
Overview
This case study analyzes two distinct pathology cases: Danny's stage 4 chronic kidney disease resulting from chemotherapy-induced nephrotoxicity and Christine's diabetic ketoacidosis. The paper examines disease pathophysiology, clinical manifestations, diagnostic criteria, and evidence-based pharmacological and medical treatment approaches for both conditions.
What this case study covers
- Part 1: Renal Disease Case - Analysis of CKD classification, manifestations, GFR assessment, and treatment options including ACE inhibitors, dialysis, and nutritional therapy
- Part 2: Diabetes Case - Examination of diabetic ketoacidosis pathophysiology, presenting symptoms, and diagnostic testing considerations

Question 1
Danny's chronic kidney disease (CKD) results from nephrotoxicity caused by chemotherapy agents used to treat his solid tumor at age 5. Nephrotoxicity refers to the damage caused to the kidneys by drugs or toxins (Arora, 2023a). Danny's CKD is classified as stage 4 or severe (GFR: 15-29 ml/min/1.73 m2) according to the Kidney Disease Improving Global Outcomes (KDIGO) classification. The primary cause of his CKD is chronic glomerulonephritis due to prolonged exposure to nephrotoxic chemotherapy drugs.
Question 2
The manifestations observed in Danny's case are:
- Peripheral edema manifests fluid retention caused by reduced glomerular filtration rate (GFR) and inadequate sodium and water excretion.
- Dry skin is caused by anemia due to CKD and a buildup of waste products in the blood, leading to itchiness and dry skin.
- Sunken eyes and tired appearance resulting from anemia and fatigue due to inadequate erythropoietin production.
- Vomiting, nausea, and lack of energy are caused by the accumulation of waste products such as urea, metabolic acidosis, and electrolyte imbalance.
Question 3
- Based on the patient's creatinine level of 543 μmol/L, it can be assumed that Danny's GFR is less than 15 ml/min/1.73 m2.
- Creatinine is a waste product of muscle metabolism. Its levels in the blood are inversely proportional to the GFR. The higher the creatinine level, the lower the GFR, which indicates a loss of kidney function.
- The GFR test measures the rate at which blood is filtered through the kidneys, which helps diagnose and stage CKD(Arora, 2023b).
