Differential Diagnosis for Chronic Diarrhea + Low Albumin + Leukocytosis + Low Platelets

  • Single Most Likely Diagnosis
    • Inflammatory bowel disease (IBD): This condition, which includes Crohn's disease and ulcerative colitis, can cause chronic diarrhea, low albumin due to malabsorption and inflammation, leukocytosis as a response to chronic inflammation, and low platelets possibly due to inflammation-induced thrombocytopenia or malabsorption of essential nutrients.
  • Other Likely Diagnoses
    • Giardiasis: Chronic giardial infection can lead to malabsorption, causing low albumin and chronic diarrhea. Leukocytosis may occur due to the body's immune response, and low platelets could be seen in severe cases due to malabsorption or immune-mediated mechanisms.
    • Celiac disease: An autoimmune reaction to gluten can cause malabsorption, leading to low albumin and chronic diarrhea. Leukocytosis and low platelets might be observed due to malabsorption of nutrients essential for hematopoiesis and immune system regulation.
    • Bacterial overgrowth (SIBO): This condition can cause malabsorption, leading to low albumin and chronic diarrhea. The immune response to bacterial overgrowth might result in leukocytosis, and low platelets could be seen due to malabsorption or an immune-mediated response.
  • Do Not Miss Diagnoses
    • Lymphoma: Both Hodgkin's and non-Hodgkin's lymphoma can present with chronic diarrhea, low albumin due to malabsorption, leukocytosis (or leukopenia), and low platelets due to bone marrow involvement. Missing this diagnosis could be fatal if not treated promptly.
    • Whipple's disease: A rare, systemic bacterial infection that can cause malabsorption, leading to low albumin and chronic diarrhea. Leukocytosis might occur due to the infection, and low platelets could result from malabsorption or bone marrow involvement.
    • Amyloidosis: This condition involves the deposition of amyloid proteins in various tissues, including the gastrointestinal tract and bone marrow, potentially causing chronic diarrhea, low albumin, leukocytosis, and low platelets. It's crucial not to miss this diagnosis due to its poor prognosis if left untreated.
  • Rare Diagnoses
    • Tropical sprue: A rare condition causing malabsorption, which can lead to low albumin and chronic diarrhea. Leukocytosis and low platelets might be observed due to malabsorption and the body's immune response.
    • Abetalipoproteinemia: A rare genetic disorder affecting fat absorption, leading to low albumin and chronic diarrhea. Leukocytosis and low platelets could be seen due to malabsorption of essential fatty acids and fat-soluble vitamins.
    • Chronic intestinal pseudo-obstruction: A rare condition characterized by impaired intestinal motility, which can cause chronic diarrhea, low albumin due to malabsorption, leukocytosis as a response to chronic illness, and low platelets possibly due to malabsorption or an immune-mediated response.
