The incidence of cutaneous adverse drug reactions (CADRs) is high in HIV-infected persons; however, there are large gaps in knowledge about several aspects of HIV-associated CADRs in Africa, which carries the biggest burden of the disease. TEN is characterized by full-thickness epidermal necrosis with an evident epidermal detachment and sloughing caused by necrosis of keratinocytes following apoptosis [49, 52]. It has a wide spectrum of severity, and it is divided in minor and major (EMM). Exfoliative dermatitis is a disease process in which most, and sometimes all, of the skin is involved in erythematous inflammation resulting in massive scaling.1 A variety of diseases and other exogenous factors may cause exfoliative dermatitis. 2022 May;35(5):e15416.

It can lead to pain, appear on large parts of the body and may require hospitalization. The approach to treatment should include discontinuation of any potentially causative medications and a search for any underlying malignancy. Downey A, et al. In HIV patients, the risk of SJS and TEN have been reported to be thousand-fold higher, roughly 1 per 1000 per year [19]. Blood counts and bone marrow studies may reveal an underlying leukemia. Hospitalization and dermatologic consultation are indicated in most cases to ensure that all of the necessary cutaneous, laboratory and radiologic investigations and monitoring are performed. Loss of normal vasoconstrictive function in the dermis, decreased sensitivity to the shivering reflex and extra cooling that comes from evaporation of the fluids leaking out of the weeping skin lesions all result in thermoregulatory dysfunction that can cause hypothermia or hyperthermia.6 The basal metabolic rate also is increased in patients with exfoliative dermatitis. In the hospital, special attention must be given to maintaining temperature control, replacing lost fluids and electrolytes, and preventing and treating infection.

It often precedes or is associated with exfoliation (skin peeling off in scales or layers), when it may also be known as exfoliative dermatitis (ED). Hypervolemia can also occur in patients with exfoliative dermatitis, contributing to the likelihood of cardiac failure.2124, In most patients with erythroderma, skin biopsies show nonspecific histopathologic features, such as hyperkeratosis, parakeratosis, acanthosis and a chronic perivascular inflammatory infiltrate, with or without eosinophils. These levels could reflect the interaction between culprit drugs and aldehyde dehydrogenase that is the enzyme which metabolizes retinoid acid. Clinical clues of a drug-induced etiology include: Abrupt onset, previous morbilliform eruption, multiple, varied cutaneous morphologic lesions present together Extensive erythema is followed in 2-6 days by exfoliative scaling Pruritus can be severe, leading to scratching and lichenification in more chronic processes 2010;85(2):1318.

Wolkenstein P, et al. In spared areas it is necessary to avoid skin detachment. In order to rule out autoimmune blistering diseases, direct immune fluorescence staining should be additionally performed to exclude the presence of immunoglobulin and/or complement deposition in the epidermis and/or the epidermal-dermal zone, absent in ED. T and NK lymphocytes can produce FasL that eventually binds to target cells. For these reasons, patients should be admitted to intensive burn care units or in semi-intensive care units where they may have access to sterile rooms and to dedicated medical personnel [49, 88]. Patch testing in severe cutaneous adverse drug reactions, including StevensJohnson syndrome and toxic epidermal necrolysis. In case of a respiratory failure, oxygen should be administrated and a NIMV may be required. Overall, T cells are the central player of these immune-mediated drug reactions.

[80], which consists of the determination of IFN and IL4 by ELISpot (Enzyme-linked immunospot assay), allowing to increase the sensitivity of LTT during acute DHR (82 versus 50% if compared to LPA). The exact role of FasL in the pathogenesis of toxic epidermal necrolysis is still questionable especially because a correlation between serum FasL levels and disease severity has not been established and because its levels have been found to be increased also in drug-induced hypersensitivity syndrome and maculopapular eruption [36]. Nat Med. TEN is also known as Lyell syndrome, since it was first described by Alan Lyell in 1956 [2, 60]. It was used with success in different case reports [114116]. Therefore, it is important to identify and treat any underlying disease whenever possible and to remove any contributing external factors.2, Most published studies of exfoliative dermatitis have been retrospective and thus do not address the issue of overall incidence. 2005;94(4):41923. 2014;71(2):27883.

Inhibition of toxic epidermal necrolysis by blockade of CD95 with human intravenous immunoglobulin. Fitzpatricks dermatology in general medicine. Allergol Int. Drugs such as paracetamol, other non-oxicam NSAIDs and furosemide, bringing a relatively low risk of SJS/TEN a priori, are also highly prevalent as putative culprit agents in large SJS/TEN registries, due to their widespread use in the general population [63, 64] (Table1). Exposure to anticonvulsivants (phenytoin, phenobarbital, lamotrigine), non-nucleoside reverse transcriptase inhibitors (nevirapine), cotrimoxazole and other sulfa drugs (sulfasalazine), allopurinol and oxicam NSAIDs [2] confers a higher risk of developing SJS/TEN. Case Presentation: We report the development of forearm panniculitis in two women during the treatment with Panitumumab (6 mg/Kg intravenous every 2 weeks) + FOLFOX-6 (leucovorin, 5- fluorouracil, and oxaliplatin at higher dosage) for the . Fournier S, et al. Sekula P, et al. If after 4days there is not an improvement it is advised to consider the association of steroid or its replacement with one of the following drugs [49, 93]: Intravenous immunoglobulins (IVIG): play their role through the inhibition of FasFas ligand interaction that it is supposed to be the first step in keratinocytes apoptosis [33]. Graft versus host disease (GVHD) Acute GVHD usually happens within the first 6months after a transplant. Other patients may warrant PUVA (psoralen plus ultraviolet A) phototherapy, systemic steroids (if psoriasis has been ruled out), retinoids (for exfoliative dermatitis secondary to psoriasis and pityriasis rubra pilaris), or immunosuppressive agents such as methotrexate (Rheumatrex) and azathioprine (Imuran).2527, When used as adjunctive therapy, behavior modification designed to eliminate persistent scratching has been successful in reducing the rate of excoriation and increasing the rate of healing.28. The clinical course of patients with malignancies depends on the type of malignancy and the response to appropriate therapy. In: Eisen AZ, Wolff K, editors.

[71] realized an algorhitm named ALDEN (algorithm of drug causality for epidermal necrolysis) which helps to establish a cause/effect relationship as probable or very probable in 70% of cases. Br J Dermatol. Once ED has occurred, it has to be managed in the adequate setting with a multidisciplinary approach, and every effort has to be made to identify and avoid the trigger and to prevent infectious and non-infectious complications. The strength of association with the development of SJS/TEN may vary among countries and historical periods, reflecting differences in ethnicities and prescription habits among the studied populations [6164]. All non-indispensable drugs have to be stopped because they could alter the metabolism of the culprit agent. 2000;115(2):14953. 8600 Rockville Pike In case of an oral mucositis that impairs nutrition, it is indicated to position a nasogastric tube.
