Psoriasis in the HIV-affected patient clinically may be FIG 1

Clinically, the skin lesions are frequently misdiagnosed as vascular tumors, especially KS. (20) No studies of this infection have been conducted in HIV-infected patients, but we have diagnosed and treated several cases at San Francisco General Hospital that had in common neutropenia and advanced HIV disease. In contrast, psoriasis vulgaris in patients with HIV may have scales that appear thick and oyster shell-like (i. Due to the constellation of clinical, histopathological and laboratory findings, the diagnosis was revised to drug hypersensitivity syndrome (based on the patient’s fever, rash, joint pain, transaminitis and anaemia) secondary to cloxacillin, seborrhoeic dermatitis and pulmonary tuberculosis (due to relapse or treatment failure). Skin punch biopsy was repeated and the findings were consistent with psoriasis (Fig. 3). Treatment of psoriasis in individuals infected with HIV constitutes a distinct challenge as HIV-associated psoriasis is a T-lymphocyte-mediated disease in the setting of T-lymphocyte depletion.

Psoriasis in the HIV-affected patient clinically may be FIG 2While psoriasis does not affect HIV survival, quality of life may be significantly impaired and these considerations warrant special attention with management. A peculiar clinical phenomenon has also been noted in which the psoriasis in patients improves shortly before death. HIV-associated psoriasis can be clinically confusing because several comorbid skin disorders in patients with HIV can mimic psoriasis. Figure 2.

(Figure 6), but biopsies from patients with DILS who are taking HAART can appear normal. Figure 2. Skin biopsy specimen. Findings include irregular psoriasiform acanthosis, a parakeratosis mound with neutrophils, minimal superficial perivascular lymphocytic infiltrate with dilated tortuous subepithelial capillaries and few plasma cells. Psoriasis in HIV-infected patients can have atypical clinical manifestations. All forms of psoriasis may progress to erythroderma (severe inflammation affecting the entire body surface, Figure 1e). Nail involvement may occur in all types of psoriasis and ranges from pits and yellowish discoloration (Figure 1i) to a severe nail deformity (onychodystrophy). In addition, exacerbation or even the initial manifestation of psoriasis has been observed in HIV infected patients.

Psoriasis in the HIV-affected patient clinically may be FIG 3In this study, we investigated whether patients with psoriasis, a common autoimmune disease of the skin, harbor genetic variants that are associated with an enhanced ability to limit replication of the HIV-1 virus. The relationship between psoriasis and HIV-1 is also interesting because of the clinical observation that HIV-1 infection can exacerbate existing psoriasis or trigger new-onset psoriasis 17.

Any drug can cause a skin reaction but some classes of drugs are characteristically associated with certain types of reaction. This has important clinical consequences, because such patients tend to be treated with broad-spectrum antibiotics which may lead to antibiotic resistance and suboptimal therapy. 1.

In some patients with HIV infection, preexisting psoriasis becomes exacerbated; in other patients, psoriasis develops within a few years after HIV infection. Trauma to the clinically uninvolved skin of patients with psoriasis can cause a lesion to appear at the exact site of injury; this phenomenon is known as the Kobner response.
