Abstract
OBJECTIVES To detect cathelicidin levels in pediatric patients with type 1 diabetes (T1D) as a potential marker for diabetic vascular complications and to assess its relation to diastolic dysfunction as an index for subclinical macrovasculopathy. METHODS Totally, 84 patients with T1D were categorized into three groups; newly diagnosed diabetes group (28 patients with a mean age of 12.38 ± 1.99) years, T1D without microvascular complications group (28 patients with a mean age of 13.04 ± 2.27), and T1D with microvascular complications group (28 patients with a mean age of 13.96 ± 2.30). Patients were evaluated using serum cathelicidin levels and echocardiography. RESULTS Total cholesterol, microalbuminuria, and cathelicidin levels were significantly higher in patients with microvascular complications when compared to the other two groups (p<0.001). Additionally, carotid intima-media thickness (CIMT) echocardiography values and diastolic functions were significantly higher in patients with complications (p<0.001). Cathelicidin was positively correlated to the duration of diabetes (r=0.542, p<0.001), total cholesterol (r=0.346, p=0.001), recurrence of hypoglycemia (r=0.351, p=0.001), recurrence of diabetes ketoacidosis (r=0.365, p=0.001), CIMT (r=0.544, p<0.001), and E/A values (r=0.405, p<0.001). CONCLUSIONS Serum cathelicidin levels can be used as an early marker for the occurrence and progression of vascular complications in patients with T1D.

[PMID: 35269741 PMCID: PMC8910759 DOI: 10.3390/ijms23052591] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 02/22/2022] [Accepted: 02/25/2022] [Indexed: 12/13/2022] Open
Abstract
Damage-associated molecular patterns (DAMPs) are endogenous danger molecules released from the extracellular and intracellular space of damaged tissue or dead cells. Recent evidence indicates that DAMPs are associated with the sterile inflammation caused by aging, increased ocular pressure, high glucose, oxidative stress, ischemia, mechanical trauma, stress, or environmental conditions, in retinal diseases. DAMPs activate the innate immune system, suggesting their role to be protective, but may promote pathological inflammation and angiogenesis in response to the chronic insult or injury. DAMPs are recognized by specialized innate immune receptors, such as receptors for advanced glycation end products (RAGE), toll-like receptors (TLRs) and the NOD-like receptor family (NLRs), and purine receptor 7 (P2X7), in systemic diseases. However, studies describing the role of DAMPs in retinal disorders are meager. Here, we extensively reviewed the role of DAMPs in retinal disorders, including endophthalmitis, uveitis, glaucoma, ocular cancer, ischemic retinopathies, diabetic retinopathy, age-related macular degeneration, rhegmatogenous retinal detachment, proliferative vitreoretinopathy, and inherited retinal disorders. Finally, we discussed DAMPs as biomarkers, therapeutic targets, and therapeutic agents for retinal disorders.

Liu L, Xie K, Yin M, Chen X, Chen B, Ke J, Wang C. Lower serum levels of vitamin D in adults with urinary tract infection. Infection 2022; 50:739-746. [PMID: 35013942 DOI: 10.1007/s15010-021-01750-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 12/20/2021] [Indexed: 11/05/2022]
Abstract
PURPOSE We aimed to explore the association between urinary tract infection (UTI) in adults and serum 25-hydroxyvitamin D (25OHD), which was used to access vitamin D status. METHODS Serum levels of 25OHD were retrospectively analyzed in 234 subjects (190 females and 44 males): 120 UTI patients (females = 103) and 114 age- and sex-matched healthy controls (females = 87). Serum 25OHD concentrations were categorized as follows: (1) < 20 ng/mL, 20 to < 30 ng/mL, and ≥ 30 ng/mL; (2) < 20 ng/mL and ≥ 20 ng/mL. RESULTS Serum 25OHD levels were lower in patients with UTI (p < 0.01). Women with UTI presented significantly lower 25OHD concentrations than those without UTI (p < 0.01). No association between serum 25OHD levels and UTI in men was found (p > 0.05). The multivariable logistic regression models showed significant associations between UTI and 25OHD, female sex, neutrophilic lymphocyte ratio and C-reactive protein (p < 0.05). CONCLUSION Lower 25OHD concentrations associated with UTI were most prominent among women. The associations between UTI and low serum 25OHD levels as well as female sex were independent of each other.
