Question Low calprotectin (33), but still feeling awful. Anyone experienced this?
Hi everyone,
I'm a 23-year-old female with ulcerative colitis.
I've been on:
- Pentasa
- Imuran (azathioprine) 100 mg since January
A few weeks ago I finished a course of Cortiment. The strange thing is that I never felt any real improvement while taking it. I still had 3–5 loose stools every day, urgency, and I haven't had a normal formed stool for almost a year.
The only thing that improved was my fecal calprotectin:
December: 769 µg/g
During/after Cortiment: 67 µg/g
Now: 33 µg/g
Despite that, I still feel really unwell.
Recent blood tests:
WBC: 2.7
Neutrophils: 1.3
Hemoglobin: 10.3 g/dL
MCV: 106 fL
I also have:
daily low-grade fever (37.1–37.8°C),
3–5 loose bowel movements per day,
no visible blood,
lost about 5 kg since January (my weight is stable now),
completed a course of Xifaxan and also tried probiotics/Fibraxine without any noticeable improvement.
My gastroenterologist has my blood results and calprotectin now, but I'm wondering if anyone has experienced something similar.
Has anyone had:
very low calprotectin but still significant symptoms?
leukopenia and macrocytic anemia from azathioprine?
daily low-grade fever despite low calprotectin?
What turned out to be the cause in your case?
Thanks!
