The general information, offending medications, complications, modified severity-of-illness score for toxic epidermal necrolysis(SCORTEN) scores, and disease outcome spectrums were analyzed.RESULTS: Drug-induced erythroderma was mostly caused by antiviral drugs, antituberculosis drugs, antibiotics, traditional Chinese medicine, and immune checkpoint inhibitors. The spectrum of sensitizing drugs was broad, the clinical situation was complex, and infections were common. The affected areas were greater than 40% body surface area in all patients. The modified SCOTERN score averaged 3.01±0.99. All patients were treated with glucocorticoids, and nine patients were treated with intravenous immunoglobulin(IVIG) pulse therapy at the same time. The average time to effectiveness was 7.08±2.23 days, and the average hospital stay was 17.92±8.46 days. Eleven patients were cured, and one patient died of secondary multiple infections, who had a modified SCORTEN score of 5 points. The mortality rate in this study was 8.3%.CONCLUSIONS: The clinical situation of AIDS patients with drug-induced erythroderma in hospitalized patients is complex and the co-infection rate is high. The use of modified SCORTEN score may objectively and accurately assess the conditions, and the use of glucocorticoid combined with IVIG therapy may improve the prognosis.展开更多

Frequency of the syncytium formation and BIV LTR directed Luc activity were in proportion to the number of input BIV infected cells. AZT inhibited the syncytium formation and the BIV LTR directed Luc gene expression level. Its inhibitory effects were dosedependent with the IC 50 being 0.24 and 0.052 mmol / L, respectively.展开更多

Both diseases share common clinical manifestations, which may lead to diagnostic difficulties, especially at the onset of the disease. Another additional challenge is when there is an association of the two pathologies. The objective of this brief review is to describe the clinical manifestations of the diseases and to make considerations regarding the moment of onset of symptoms. Knowledge of these common manifestations and their peculiarities may alert clinicians to possible diagnoses and avoid errors in the evaluation and conduction of these patients.展开更多

HIV-salivary gland disease(HIV-SGD) is comprehensively ascertained amongst the major critical acquired immunodeficiency syndrome(AIDS)-relatedoral manifestation and causes substantial morbidity. Parotid gland swelling due to sicca syndrome, parotid lipomatosis, sialadenitis, diffuse infiltrative lymphocytosis syndrome, benign lymphoepithelial lesions, neoplasms(benign or malignant) of salivary gland, parotid gland inflammation, diminished flow rates of saliva and xerostomia have been documented that also affects the health- associated characteristics of life in subjects infected with HIV. There is a necessity for health care researchers to diagnose it, particularly as it might worsen if left undiagnosed. The precise characteristic of alterations in dynamics of salivary gland structure and functionality with long-standing usage of highly active anti-retroviral therapy still remains unknown. HIV positive children also present with bilateral parotid enlargement and the syndrome state with classical clinical and cytological features of predominated lymphoid hyperplasia. Though various case reports and studies have been extensively published on different aspects of HIV-SGD, it has not been described solely, thus leading to occasional confusion of nomenclature and clinical presentation of HIV-SGD. This article reviews the pathogenesis of HIV-related SGD and its components and various other miscellaneous disorders affecting the salivary glands in HIV/AIDS.展开更多
