Sweet's syndrome (SS) is associated with various diseases including non‐tuberculous mycobacterial infection (NTM). Recent reports have shown that SS associated with NTM is increasing. Clinical features of SS associated with NTM may be different from SS associated with other associated diseases. The aim of the present study was to compare clinical parameters and treatment outcomes of SS associated with NTM and other associated diseases. Patients from January 2004 to April 2014 diagnosed with SS were retrospectively enrolled. Clinical variables were compared between SS patients with and without NTM infection. There were 51 SS patients during the study period; 36 patients (70.59%) had NTM. Clinical variables between the NTM and other associated diseases were comparable: age, sex, and pattern and locations of skin lesions. Five laboratory factors were significantly different between the groups including white blood cell counts (NTM 25 800 vs 12 850 cells/mm3), lymphocyte percentages (13.0% vs 18.7%), monocytes (3.0% vs 7.2%), blood urea nitrogen (BUN) (11.7 vs 8.1 mg/dL) and serum creatinine (Cr) (1.0 vs 0.7 mg/dL). The presence of markedly high white blood cell counts, a low percentage of mononuclear cells and high BUN/Cr levels in SS may be a clinical clue to recognize the association with NTM infections; particularly in dissemination. 相似文献

Systemic scleroderma—also known as systemic sclerosis (SSc)—is a chronic systemic connective tissue disease characterized by collagen deposition in cutaneous and internal organs, leading to skin sclerosis and multiple organ fibrosis. The pathogenesis is complex and remains poorly understood. Treatment is based on organ involvement and requires a multidisciplinary approach. Skin sclerosis can cause disability, leading to decreasing quality of life. Various systemic antifibrotic therapies have been used; however, most have unsatisfactory results. Recently, phototherapy and in particular ultraviolet A (UVA) has been used to treat skin sclerosis in SSc patients with satisfactory results. The main mechanisms include lymphocyte apoptosis, cytokine alteration, inhibition of collagen synthesis and increased collagenase production, and neovascularization, leading to the breakdown of collagen fibrils resulting in skin softening or even healing digital ulcers. Most studies reported that psoralen plus UVA (PUVA) and UVA1 phototherapy improved clinical outcomes vis‐à‐vis skin sclerosis, joint mobility, ulcers, and histopathology. PUVA and UVA1 phototherapy therefore have potential as an alternative or adjunctive therapy for patients with SSc. 相似文献
