Objective  To evaluate the relationship between frequency of pruritic symptoms experienced over a 1-month period and psychological stress.

Design  Cohort study.

Setting  Population-based study in Japan.

Participants  A total of 2224 participants at least 18 years old and without psychiatric disorders participated in the Japan Health Diary Study (October 2003), a cohort study comprising a representative sample in Japan.

Main Outcome Measures  Frequency of pruritic symptoms assessed by self-reported health diaries over the 1-month period and subsequent psychological stress measured using the Japanese version of the Perceived Stress Scale.

Results  The 2224 participants had a mean age of 44.6 years, 1212 (54.5%) were women, and 70 (3.1%) presented with pruritic symptoms. Multivariable analysis showed that patients with pruritic symptoms had significantly higher psychological stress than those without pruritic symptoms (β coefficient, 2.33; 95% confidence interval [CI], 0.53-4.14; P = .01). Furthermore, a linear trend was observed between increased psychological stress and increased severity of pruritic symptoms, with β coefficients for the first, second, and third tertiles for symptoms of 0.81 (95% CI, –1.97 to 3.59), 1.77 (95% CI, –0.82 to 4.37), and 4.86 (95% CI, 1.29 to 8.43), respectively (P value for trend, .004).

Conclusion  Our results suggest that frequency of pruritic symptoms is associated with psychological stress in the general population.

Leukocyte mono-immunoglobulin (Ig)–like receptor 5 (LMIR5)/CD300b is a DAP12-coupled activating receptor predominantly expressed in myeloid cells. The ligands for LMIR have not been reported. We have identified T cell Ig mucin 1 (TIM1) as a possible ligand for LMIR5 by retrovirus-mediated expression cloning. TIM1 interacted only with LMIR5 among the LMIR family, whereas LMIR5 interacted with TIM4 as well as TIM1. The Ig-like domain of LMIR5 bound to TIM1 in the vicinity of the phosphatidylserine (PS)-binding site within the Ig-like domain of TIM1. Unlike its binding to TIM1 or TIM4, LMIR5 failed to bind to PS. LMIR5 binding did not affect TIM1- or TIM4-mediated phagocytosis of apoptotic cells, and stimulation with TIM1 or TIM4 induced LMIR5-mediated activation of mast cells. Notably, LMIR5 deficiency suppressed TIM1-Fc–induced recruitment of neutrophils in the dorsal air pouch, and LMIR5 deficiency attenuated neutrophil accumulation in a model of ischemia/reperfusion injury in the kidneys in which TIM1 expression is up-regulated. In that model, LMIR5 deficiency resulted in ameliorated tubular necrosis and cast formation in the acute phase. Collectively, our results indicate that TIM1 is an endogenous ligand for LMIR5 and that the TIM1–LMIR5 interaction plays a physiological role in immune regulation by myeloid cells.
