Gleich syndrome: a systematic review

Characterized chiefly by hypereosinophilia and angioedema, Gleich syndrome is a rare disorder with unclear clinical and therapeutic findings. Other symptoms include increased IgM levels, weight gain, fever, and urticaria. Herein we review Gleich syndrome and assess clinical features, epidemiology, and treatment options. Thirty-two articles including case reports or case series of eosinophilic angioedema and Gleich syndrome were included. Data regarding patient age, gender, and history, clinical and biological manifestations, and treatment protocols were recorded. The most common clinical findings include recurrent or non-recurrent angioedema, fever, urticaria, weight gain, blood eosinophilia, and elevated immunoglobulin levels. Corticosteroid therapy is the mainstay of treatment. Gleich syndrome is a distinctive hypereosinophilic entity with a benign course and good response to systemic corticosteroids. More studies are needed to evaluate the pathophysiology of this syndrome and lead to better therapeutic options.     

Ciliary melanin-concentrating hormone receptor 1 (MCHR1) is widely distributed in the murine CNS in a sex-independent manner

Melanin-concentrating hormone (MCH) is a ubiquitous vertebrate neuropeptide predominantly synthesized by neurons of the diencephalon that can act through two G protein-coupled receptors, called MCHR1 and MCHR2. The expression of Mchr1 has been investigated in both rats and mice, but its synthesis remains poorly described. After identifying an antibody that detects MCHR1 with high specificity, we employed immunohistochemistry to map the distribution of MCHR1 in the CNS of rats and mice. Multiple neurochemical markers were also employed to characterize some of the neuronal populations that synthesize MCHR1. Our results show that MCHR1 is abundantly found in a subcellular structure called the primary cilium, which has been associated, among other functions, with the detection of free neurochemical messengers present in the extracellular space. Ciliary MCHR1 was found in a wide range of areas, including the olfactory bulb, cortical mantle, striatum, hippocampal formation, amygdala, midline thalamic nuclei, periventricular hypothalamic nuclei, midbrain areas, and in the spinal cord. No differences were observed between male and female mice, and interspecies differences were found in the caudate-putamen nucleus and the subgranular zone. Ciliary MCHR1 was found in close association with several neurochemical markers, including tyrosine hydroxylase, calretinin, kisspeptin, estrogen receptor, oxytocin, vasopressin, and corticotropin-releasing factor. Given the role of neuronal primary cilia in sensing free neurochemical messengers in the extracellular fluid, the widespread distribution of ciliary MCHR1, and the diverse neurochemical populations who synthesize MCHR1, our data indicate that nonsynaptic communication plays a prominent role in the normal function of the MCH system.
