The immune-stromal cell interactions play a key role in health and diseases. In periodontitis, the most prevalent infectious disease in humans, immune cells accumulate in the oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand (RANKL) expression in osteogenic cells such as osteoblasts and periodontal ligament cells. However, the detailed mechanism underlying immune–bone cell interactions in periodontitis is not fully understood. Here, we performed single-cell RNAsequencing analysis on mouse periodontal lesions and showed that neutrophil–osteogenic cell crosstalk is involved in periodontitis-induced bone loss. The periodontal lesions displayed marked infiltration of neutrophils, and in silico analyses suggested that the neutrophils interacted with osteogenic cells through cytokine production. Among the cytokines expressed in the periodontal neutrophils, oncostatin M (OSM) potently induced RANKL expression in the primary osteoblasts, and deletion of the OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss. Epigenomic data analyses identified the OSM-regulated RANKL enhancer region in osteogenic cells, and mice lacking this enhancer showed decreased periodontal bone loss while maintaining physiological bone metabolism. These findings shed light on the role of neutrophils in bone regulation during bacterial infection, highlighting the novel mechanism underlying osteoimmune crosstalk.

The Spectrum of Nail Disorders in Patients with End-Stage Renal Disease Undergoing Conservative Treatment: A Case-Control Study

引用

International Journal of Dermatology and Venereology 2024年第3期7卷 150-154页

作者： Shigidi M.M.T. Department of internal medicine College of Medicine Jouf University Al Jouf 72388 Saudi Arabia Nephrology Division Department of Medicine Baraha Medical City North Khartoum State Khartoum 13311 Sudan

Objective: Various nail disorders have been reported in patients with chronic kidney disease. However, few studies have investigated nail disorders in patients with advanced chronic kidney disease. This study focused on nail disorders seen in patients with end-stage renal disease (ESRD) undergoing conservative treatment. Methods: A case-control study was conducted at Baraha Medical City in Khartoum State, Sudan. Data on patients with ESRD who were on conservative treatment and presented for follow-up between March and September 2021 were collected. Patients' demographic features, nail findings on clinical examination, and laboratory results were recorded. The obtained data were compared with those on age- and sex-matched healthy individuals from the general population. The chi-square test and Student t test were performed to analyze categorical and numerical variables, respectively. Results: Data on 78 patients with ESRD were studied. Their mean age was 54.6 ± 17.6 years, and 45 (57.7%) were men. These patients were compared with 129 controls. Nail disorders were seen in 65 (83.3%) ESRD patients and 86 (66.6%) controls (P = 0.009). Patients with ESRD were found to be at increased relative risk of developing a wide spectrum of nail disorders. An absent lunula, half-and-half nails, nail dystrophy, Terry's nails, onychomycosis, and koilonychia were the most common disorders and were seen in 44 (56.4%), 13 (16.7%), 10 (12.8%), 9 (11.5%), 6 (7.7%), and 5 (6.4%) patients, respectively. Patients with ESRD had a statistically significant risk of developing above diseases (all P < 0.05). Conclusion: The current study demonstrated a wide spectrum of nail disorders in patients with ESRD undergoing conservative treatment. Further studies are essential to understand their pathogenesis. © 2024 Hospital for Skin Diseases (Institute of Dermatology), Chinese Academy of Medical Sciences, and Chinese Medical Association, published by Wolters Kluwer, Inc.

Case Report: Carnitine Palmitoyl Transferase II (CPT II) Deficiency

引用

Open Journal of internal medicine 2024年第1期14卷 93-101页

作者： Kathy Po Marius Chivu Edwin Rosas Balpreet Kaur Department of internal medicine Saint James School of Medicine The Quarter Anguilla Department of internal medicine Medicine at University of Chicago Chicago USA Department of internal medicine Medical College of Wisconsin Wisconsin USA

Carnitine Palmitoyl Transferase II (CPTII) is a very important enzyme that helps with the oxidation of long-chain fatty acid to produce energy. Deficiency in CPTII will lead to energy deficiency in the case of fasting and the accumulation of the long chain fatty in the body. There are three types of CPT II deficiency, the myopathic form, the severe infantile hepatocardiomuscular form and the lethal neonatal form. They are all inherited as an autosomal recessive. Diagnosis of the CPTII are 1) tandem mass spectrometry (MS/MS) in adult form and 2) CPTII polymorphism (F352C), which is linked to reducing the activity of CPTII in infantile form [1]. Glucose is the primary management and medium-chain fatty acid is an alternative due to the bypass of the CPTII enzyme in the pathway. For the prevention of CPTII deficiency are to avoid long chain fatty acid (C12-fatty acid), fasting, prolonged exercise, known triggers, and certain medications such as anti-epileptics and general anesthesia. During the rhabdomyolysis and myoglobinuria attack, it is very important to maintain hydration to avoid acute renal failure. If, however, renal failure occurs, dialysis is recommended. We present a case of a 27-year-old African American woman with the significant past medical history of CPT II deficiency leading to recurrent rhabdomyolysis and myoglobinuria. Together with all the research studies from diagnosis to treatment of CPTII deficiency will help in clinical management of patients. And this case report will add to the existing case reports of patients who have CPTII deficiency in terms of how we diagnose, how we treat, and how we prevent symptoms from re-occurring.
