These components may be categorized as attachment of the viral surface envelope protein subunit, gp120, to the CD4+ receptor and chemokine coreceptors, CCR5 and CXCR4, present on T cell surface. The viral fusion protein, gp41, the second cleaved subunit of Env undergoes reconfiguration and the membrane fusion reaction itself. Since the CD4+ T cell population is actively involved; the ultimate outcome of human immunodeficiency virus infection is total collapse of the host immune system. Mathematical modeling of the stages in viral membrane protein-host cell receptor-coreceptor interaction and the effect of antibody vaccine on the viral entry into the susceptible host cell has been carried out using as impulsive differential equations. We have studied the effect of antibody vaccination and determined analytically the threshold value of drug dosage and dosing interval for optimum levels of infection. We have also investigated the effect of perfect adherence of drug dose on the immune cell count in extreme cases and observed that systematic drug dosage of the immune cells leads to longer and improved lives.展开更多

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

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
