Abstract

We have recently demonstrated that serotonin (5-HT) increases the production of type 4 collagen by cultured human mesangial cells. Here we examined the clinical effects of a 5-HT(A2) receptor antagonist whether it would prevent the development or progression of diabetic nephropathy. We compared the levels of 5-hydroxyindole-3-acetic acid (5-HIAA), the major metabolite of 5-HT, in 24-h urine samples of patients with type 2 diabetes (n=110) and normal subjects (n=40). We then investigated the effects of 24-month treatment with sarpogrelate hydrochloride, a 5-HT(A2) receptor antagonist, on urinary albumin level in 10 type 2 diabetics with microalbuminuria, compared with not treated control group. Urinary 5-HIAA in diabetic patients was significantly higher (3.44+/-1.43 mg/day) than in normal subjects (1.62+/-0.50 mg/day, P<0.001), and correlated significantly with hemoglobin A1c (r=0.56, P<0.001) and with fasting blood glucose (r=0.37, P<0.001). Sarpogrelate significantly reduced urinary albumin excretion level within 3 months of commencement of treatment (24.3+/-8.58 mg/g Cr, P<0.05), which was persistently seen during the treatment, while no such change was noted in the control group (32.2+/-13.4 mg/g Cr). Our study indicate that high levels of 5-HT in type 2 diabetics may be one of the underlying mechanisms of diabetic nephropathy, and that treatment with 5-HT(A2) receptor antagonists may reduce or inhibit the development of nephropathy.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Gut-derived 5-HT can modulate glucose and energy homeostasis and is augmented in patients with type 2 diabetes and the obese.

    “Furthermore, gut-derived 5-HT can also modulate glucose and energy homeostasis (68-70), and is augmented in patients with type 2 diabetes (71) and the obese (9).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
