Dystrophic calcinosis: structural and morphological composition, and evaluation of ethylenediaminetetraacetic acid ('EDTA') for potential local treatment. Arthritis Res Ther 2024; 26:102. [PMID: 38778407 PMCID: PMC11110335 DOI: 10.1186/s13075-024-03324-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Accepted: 04/20/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND To perform a detailed morphological analysis of the inorganic portion of two different clinical presentations of calcium-based deposits retrieved from subjects with SSc and identify a chemical dissolution of these deposits suitable for clinical use. METHODS Chemical analysis using Fourier Transform IR spectroscopy ('FTIR'), Raman microscopy, Powder X-Ray Diffraction ('PXRD'), and Transmission Electron Microscopy ('TEM') was undertaken of two distinct types of calcinosis deposits: paste and stone. Calcinosis sample titration with ethylenediaminetetraacetic acid ('EDTA') assessed the concentration at which the EDTA dissolved the calcinosis deposits in vitro. RESULTS FTIR spectra of the samples displayed peaks characteristic of hydroxyapatite, where signals attributable to the phosphate and carbonate ions were all identified. Polymorph characterization using Raman spectra were identical to a hydroxyapatite reference while the PXRD and electron diffraction patterns conclusively identified the mineral present as hydroxyapatite. TEM analysis showed differences of morphology between the samples. Rounded particles from stone samples were up to a few micron in size, while needle-like crystals from paste samples reached up to 0.5 µm in length. Calcium phosphate deposits were effectively dissolved with 3% aqueous solutions of EDTA, in vitro. Complete dissolution of both types of deposit was achieved in approximately 30 min using a molar ratio of EDTA/HAp of ≈ 300. CONCLUSIONS Stone and paste calcium-based deposits both comprise hydroxyapatite, but the constituent crystals vary in size and morphology. Hydroxyapatite is the only crystalline polymorph present in the SSc-related calcinosis deposits. Hydroxyapatite can be dissolved in vitro using a dosage of EDTA considered safe for clinical application. Further research is required to establish the optimal medium to develop the medical product, determine the protocol for clinical application, and to assess the effectiveness of EDTA for local treatment of dystrophic calcinosis.

Abstract
Commonly associated with autoimmune and renal disorders, calcinosis cutis is a disorder of systemic calcium deposition in soft tissues. The pathophysiology of such deposition varies based on subtype, therefore treatment options vary not only in terms of severity of disease but also with subtype. This case report describes a 52-year-old female with systemic sclerosis and an extensive past medical history who initially presented with complaints of worsening left lower leg pain, a negative workup for deep vein thrombosis, and an extensive palpable mass in the posterior thigh with erythema, drainage, and purulence. With multiple treatment options exhausted from her autoimmune disorders, she ultimately required surgical resection for her refractory infected calcinosis cutis. Identification of calcinosis cutis subtype in conjunction with appropriate history and physical is crucial to determining indications for treatment.

Abstract
PURPOSE OF REVIEW To provide updated information on the prevalence, pathogenesis, diagnostics, and therapeutics of calcinosis cutis associated with systemic sclerosis (SSc). RECENT FINDINGS Observational studies show ethnic and geographical differences in the prevalence of calcinosis. In addition to clinical and serological associations, biochemical studies and in-vivo models have attempted to explain theories behind its pathogenesis, including prolonged state of inflammation, mechanical stress, hypoxia, and dysregulation in bone and phosphate metabolism. Long-term use of proton pump inhibitors may increase the risk for calcinosis in SSc. Few single center observational studies have shown mild benefit with minocycline and topical sodium thiosulfate. SUMMARY Calcinosis cutis is the deposition of insoluble calcium in the skin and subcutaneous tissues. It affects up to 40% of SSc patients and causes significant morbidity. Long disease duration, features of vascular dysfunction, and osteoporosis have been associated with calcinosis. Altered levels of inorganic pyrophosphate and fibroblast growth factor-23 have been implicated in dysregulated phosphate metabolism that may lead to calcinosis in SSc. Plain radiography can help with diagnosis and quantifying the calcinosis burden. Surgical treatment remains the most effective therapy when feasible. At present, no medical therapies have proven efficacy in large randomized controlled trials.

Abstract
RATIONALE Calcinosis cutis is a rare skin disease, and idiopathic cases are rarely reported. It is characterized by the deposition of insoluble calcium salts in the skin, subcutaneous tissue, superficial muscles, and tendon sheaths. However, no abnormal changes were found in the bone. In this article, we introduce a case of idiopathic calcinosis cutis of the buttocks with a long course and large lesion area. PATIENT CONCERNS A 51-year-old male patient was admitted to the hospital with a chief complaint of 'Due to the discovery of hard nodules with pruritus in the buttocks for 32 years. The patient was a male who was 51 years old. He has been in good health and reported no history of surgery, trauma, infection, metabolic disease, tumor, or other diseases. There was no family history. It is worth noting that the patient has the occupation of driving trucks, which keeps him sedentary. DIAGNOSES The accurate diagnosis of calcinosis cutis was confirmed by postoperative histopathological examination with many local calcifications and multinucleated giant cells in subcutaneous tissue. INTERVENTIONS The patient underwent skin lesion excision and autologous skin grafting under general anesthesia. A medium-thickness skin graft from the left lateral thigh was transplanted into the hip operation area, and a bolus tie-over pressure dressing was applied. After the operation, the patient received anti-infection treatment and was advised to rest in the prone position to prevent extrusion of the operation area. OUTCOMES The postoperative recovery was good, and there was no recurrence after 4 months of follow-up. LESSONS The incidence rate of cutaneous calcinosis is not clear. This patient had a large lesion area, long onset time, an invasion of the fat layer, and the onset site was located in the sacrococcygeal region. It is necessary to choose appropriate treatment methods.

Abstract
The enlightenment of the formation of neutrophil extracellular traps (NETs) as a part of the innate immune system shed new insights into the pathologies of various diseases. The initial idea that NETs are a pivotal defense structure was gradually amended due to several deleterious effects in consecutive investigations. NETs formation is now considered a double-edged sword. The harmful effects are not limited to the induction of inflammation by NETs remnants but also include occlusions caused by aggregated NETs (aggNETs). The latter carries the risk of occluding tubular structures like vessels or ducts and appear to be associated with the pathologies of various diseases. In addition to life-threatening vascular clogging, other occlusions include painful stone formation in the biliary system, the kidneys, the prostate, and the appendix. AggNETs are also prone to occlude the ductal system of exocrine glands, as seen in ocular glands, salivary glands, and others. Last, but not least, they also clog the pancreatic ducts in a murine model of neutrophilia. In this regard, elucidating the mechanism of NETs-dependent occlusions is of crucial importance for the development of new therapeutic approaches. Therefore, the purpose of this review is to address the putative mechanisms of NETs-associated occlusions in the pathogenesis of disease, as well as prospective treatment modalities.
