A dysregulated immune response characterized by the hyperproduction of several pro-inflammatory cytokines (a.k.a. 'cytokine storm') plays a central role in pathophysiology severe coronavirus disease 2019 (COVID-19) caused acute respiratory syndrome 2 (SARS-CoV-2). In this Perspective article we discuss evidence for synergistic anti-inflammatory and immunomodulatory properties exerted vitamin D dipeptidyl peptidase-4 (DPP-4) inhibitors, latter being class antihyperglycemic agents used...

Type 1 diabetes mellitus (T1DM) is a chronic disease characterized by autoimmune destruction of pancreatic beta cells and inadequate insulin production. Remission criteria in T1DM take into account serum levels C-peptide glycosylated hemoglobin, as well the dose administered to patient. However, remission lasting longer than year rare. We describe here cases two young women who presented with positive glutamic acid decarboxylase (GAD) antibody classic clinical manifestations T1DM. Both...

The occurrence of partial remission (honeymoon phase) in type 1 diabetes (T1D) has been associated with a reduced risk chronic microvascular complications diabetes. We have published case reports showing that combination therapy the DPP-4 inhibitor sitagliptin plus vitamin D3 (VIDPP-4i) can prolong honeymoon phase patients new-onset T1D. In present case-control study, we investigated frequency clinical (CR) T1D after VIDPP-4i treatment.In this collected data spanning 10 years from medical...

Leukocytoclastic vasculitis (LCV) is a small vessel involving arterioles, capillaries and postcapillary venules. LCV generally confined to the skin, with extracutaneous manifestations occurring less frequently. has multiple potential etiologies. Indeed, histological can be found in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, immune complex associated systemic diseases (i.e. sarcoidosis, Sjögren's syndrome, rheumatoid arthritis, lupus erythematosus), or cancer,...

Type 1 diabetes (T1D) represents an autoimmune disease caused by the gradual immune-mediated destruction of insulin-producing beta cells within pancreatic islets Langerhans, resulting in lifelong need for exogenous insulin therapy. According to recent estimates, T1D currently affects about 8.4 million individuals worldwide. Since a definitive biological cure this is not available yet, there great novel therapeutic strategies aimed at safely and effectively altering natural history during its...

Background: The incidence of Type 1 Diabetes Mellitus (T1DM) is on the rise. Since there no curative treatment, it urgent to look for therapies that can delay disease progression and protect pancreatic β-cells. Dipeptidyl peptidase-4 inhibitors (DPP-4i) have shown potential in modulating inflammation preventing β-cell destruction. This protocol describes an upcoming trial evaluate effectiveness DPP-4i alogliptin delaying stage 2 (presymptomatic) 3 (symptomatic) T1DM. Patients Methods: We...

<h3>Background:</h3> Spondyloarthritis (SpA) has been classified as an 'MHC-I-opathy,' with HLA-B27 recognized a major genetic factor half century ago [1]. Additionally, other MHC-I alleles, including HLA-B7, B35, B38, and B40 (B60/B61), have implicated in increasing the risk of SpA [2-4]. A recent publication from our group showed overall positivity rate 4.35% Brazilian healthy people [5]. <h3>Objectives:</h3> To evaluate each allelic frequency (AF) HLA-B to assess whether frequencies...
