Differential Diagnosis for Scamp

Based on the laboratory results provided, the following differential diagnoses are considered:

• Single Most Likely Diagnosis

  • Anemia of Chronic Disease: The patient's low hemoglobin (Hgb 11.1) and hematocrit (HCT 33.4) levels, along with an elevated erythrocyte distribution width (EDW 82.6), suggest anemia. The presence of elevated CRP (11.2) indicates chronic inflammation, which is consistent with anemia of chronic disease. The iron level is within normal limits, but the percent saturation is low, which can be seen in anemia of chronic disease due to impaired iron utilization.

• Other Likely Diagnoses

  • Chronic Kidney Disease (CKD): Although the GFR is 72, which is within the normal range, the creatinine level is slightly elevated (0.87), and the potassium level is high (5.2). These findings, combined with the patient's age, suggest the possibility of early CKD.
  • Hypertriglyceridemia: The patient's triglyceride level is elevated (67), which may contribute to cardiovascular risk.
  • Vitamin D Deficiency: Although the vitamin D level is 43.2, which is considered insufficient, it is not severely deficient. However, vitamin D insufficiency can contribute to various health issues, including osteoporosis and increased risk of falls.

• Do Not Miss Diagnoses

  • Multiple Myeloma: The elevated CRP and anemia could be indicative of a paraproteinemia, such as multiple myeloma. Although the patient's age and laboratory results do not strongly suggest this diagnosis, it is essential to consider it due to its potential severity.
  • Chronic Inflammatory Disease: The elevated CRP level suggests chronic inflammation, which could be due to various conditions, such as rheumatoid arthritis, lupus, or other autoimmune diseases.
  • Hypothyroidism: Although not directly indicated by the laboratory results, hypothyroidism can cause anemia, elevated cholesterol, and other metabolic changes. It is essential to consider this diagnosis due to its potential impact on the patient's quality of life.

• Rare Diagnoses

  • Myeloproliferative Neoplasm: The elevated erythrocyte count and hemoglobin level could suggest a myeloproliferative neoplasm, such as polycythemia vera. However, the patient's age and laboratory results do not strongly support this diagnosis.
  • Hemochromatosis: The patient's iron level is within normal limits, but the percent saturation is low. Although hemochromatosis is unlikely, it is essential to consider it due to its potential severity and the need for genetic counseling.
