Sarcoidosis is a systemic inflammatory disease, affecting any organ, and that can be discovered by accident in approximately 5% of cases. High levels of the type-1 helper (Th1)-dependent chemokine, monokine induced by interferon (IFN)-γ (MIG)/chemokine (C-X-C motif) ligand (CXCL)9, and its receptor CXCR3 have been reported in bronchoalveolar lavage and biopsy samples of patients with sarcoidosis. These elevated levels are related with the amount of CD4+ lymphocytes and total lymphocytes. Read More

Department of Clinical and Experimental Medicine, University of Pisa, Pisa, Italy.

The importance of the Type-1 helper immune response in the development of Vitiligo (Vit), and of chemokine receptor (CXCR)3 receptor and its chemokine monokine induced by interferon (IFN)-γ(MIG) has been shown by several studies. MIG/ interferon (IFN)-γ-inducible protein 10 (IP10) /CXCR3 axis mediated T-cell recruitment into the skin in Vit is an early event in the progression of the disease. MIG and IP10 circulating levels are increased in progressive Vit. Read More

Department of Clinical and Experimental Medicine, University of Pisa, Pisa, Italy.

Monokine induced by interferon (IFN)-γ (MIG) / chemokine (C-X-C motif) ligand 9 (CXCL)9 is involved in the pathogenesis of psoriatic arthritis (PsA). It was demonstrated that both blood plasma-derived dendritic cells (pDCs) and pDCs isolated from rheumatoid arthritis (RA) and PsA synovial fluid (SF), expressed CXC receptor (R) 3 and CXCR4, and that the chemotaxis of blood-derived pDCs is stimulated by MIG, (IFN)-γ-inducible protein 10 (IP-10)/CXCL10, IFN-inducible T-cell α chemoattractant (I-TAC) )/CXCL11 and stromal cell-derived factor 1 (SDF-1)/ CXCL12, present in RA and PsA SF. In PsA patients have been found a Th1 immune predominance at early stage of disease, while a reduction of these chemokines has been observed in long lasting PsA, with a significant increase of monocyte chemoattractant protein-1/IP-10 ratio.

Efficacy and Safety of 22-Oxa-Calcitriol in Patients with Rheumatoid Arthritis: A Phase II Trial.

Med Sci Monit 2018 Dec 16;24:9127-9135. Epub 2018 Dec 16.

Department of Neurology Intensive Care Unit, The Affiliated Hospital of Xuzhou Medical University, Xuzhou, Jiangsu, China (mainland).

BACKGROUND Calcitriol (1 alpha, 25-dihydroxy vitamin D3) is a good vitamin D supplement but can cause hypercalcemia. Whereas, 22-oxa-1 alpha, 25-dihydroxy vitamin D3 (22-oxa-calcitriol) has less hypercalcemic activity than calcitriol and is reported to be effective for cell-proliferative diseases. The objective of the study was to compare renal function and blood tests of arthritis patients receiving calcitriol supplements with those receiving 22-oxa-calcitriol supplements. Read More

A Family with Autosomal Dominant Distal Renal Tubular Acidosis Presents with Atypical Phenotype Caused by a Missence Mutation (R388C) of the Human Kidney Anion Exchanger.

Nephron 2018 Dec 14:1-6. Epub 2018 Dec 14.

Department of Endocrinology and Metabolism, Institute of Endocrinology, Liaoning Provincial Key Laboratory of Endocrine Diseases, The First Affiliated Hospital of China Medical University, Shenyang,

Hereditary forms of distal renal tubular acidosis (dRTA) are rare and mainly caused by mutations in ATP6V1B1, ATP6V0A4 and SLC4A1. About 20 mutations in SLC4A1 gene have been found that are related to either autosomal dominant (AD) or autosomal recessive dRTA. AD dRTA often manifest as constitutional and can easily be delayed in diagnosis and treatment. Read More
