JCV detection in urine, serum and PBMCs of natalizumab-treated MS patients
| Patients (nr) | Median VLa | Median VL (IQR)b | |
|---|---|---|---|
| PBMCs |
4/24* |
3 x 102 |
2.45 (2.28-3.11) |
| serum |
4/24#† |
3.75 x 103 |
3.53 (3.11-3.82) |
| urine | 11/24*† | 4.1 x 105 | 5.60 (5.08-5.84) |
a Viral loads (VL) are expressed as viral copies/ml in urine and in serum, as copies/μg of DNA in PBMCs. bVL median values and interquartile range (IQR) are expressed as Log10 copies.
* † Fisher exact test : PBMCs or serum vs. urine p= 0.062.
