Porphyria cutanea tarda (PCT), a relatively uncommon disease, has recently been reported in patients infected with the human immunodeficiency virus (HIV). Although PCT and HIV infection may co-exist by chance, the increasing number of reported cases suggest that HIV or an associated factor triggers the development of PCT in predisposed individuals. We report four additional cases of PCT in HIV seropositive patients and review the previously reported cases. The possible links between PCT and HIV are discussed. We believe the diagnosis of PCT should prompt investigation for HIV infection in all patients.

A case of porphyria cutanea tarda in a human immunodeficiency virus-infected patient with hemophilia is reported. Onset of skin manifestations of porphyria cutanea tarda coincided with deterioration of immune function. However, acquired immunodeficiency syndrome has not yet developed with a follow-up interval of 39 months. Treatment with zidovudine and topical steroids has resulted in significant improvement in the skin lesions. The clinical features of 11 other reported cases of human immunodeficiency virus-associated porphyria cutanea tarda are reviewed. The data suggest that a true association exists between human immunodeficiency virus infection and porphyria cutanea tarda, with onset of clinical signs of porphyria cutanea tarda coincident with declining immunologic function.

Porphyria cutanea tarda (PCT) is a disorder of heme synthesis characterized by (a) a diminished activity of uroporphyrinogen decarboxylase biochemically and (b) cutaneous lesions secondary to a delayed type of photosensitivity clinically. A human immunodeficiency virus (HIV)-infected patient with PCT is reported and the world literature is reviewed. To date, 17 HIV-seropositive men with PCT have been described. The initial appearance of PCT occurred before or concurrent with the diagnosis of HIV infection in 71% of these individuals (12 men). The median age at onset of PCT was 36 years (range of 20 to 69 years); the median age for the detection of HIV infection was 35 years (range of less than 20 to 71 years). All of these patients had elevated levels of urine porphyrins and blisters on their dorsal hands. Abnormal liver function tests, erosions, hyperpigmentation, hypertrichosis, and skin fragility were also present in some of the men. Polycythemia, serologic evidence of increased iron stores, scarring, milia, and sclerodermoid changes were rarely observed. Successful therapeutic approaches for PCT in men with HIV infection included (a) elimination of PCT-precipitating agents, (b) avoidance of sun exposure, and (c) periodic phlebotomy. Multiple hypotheses for an etiologic role of the HIV and/or an HIV-associated infection, directly or indirectly, in the pathogenesis of PCT in HIV-seropositive men have been suggested.

The human immunodeficiency virus type 1 (HIV-1) has been isolated from a number of body fluids, including semen, tears, cerebrospinal fluid, saliva, breast milk, alveolar fluid, and vaginal fluid, but it has not been isolated from fluid-containing skin lesions. We report the isolation of HIV-1 from cutaneous blister fluid in a patient with concomitant HIV-1 infection and porphyria cutanea tarda. Although transmission of HIV-1 through casual contact has not been reported, appropriate precautions should be taken to avoid direct contact with cutaneous fluid-containing lesions in HIV-1-positive patients.

We report the cases of 4 male subjects, 29, 32, 41 and 44 years old, presenting isolated seropositivities for the human immunodeficiency virus (HIV), or full-blown acquired immunodeficiency syndrome, associated with a typical porphyria cutanea tarda (PCT). The 4 patients are in the usual risk groups for HIV infection. Viral hepatitis was observed in 3 of the 4 cases. Over the past 3 years, 15 cases associating HIV infection and PCT have been reported; almost all had the usual risk factors for HIV infection and hepatopathy. We speculate that HIV infection may have favored the occurrence of early PCT in these cases by altering the metabolism of the porphyrins, either directly or by means of the associated hepatopathy.

Two male patients, each of whom had one or more risk factors for human immunodeficiency virus, subsequently developed findings of porphyria cutanea tarda preceding diagnosis of acquired immune deficiency syndrome (AIDS).

A recent report documents three homosexual men with porphyria cutanea tarda associated with acquired immune deficiency syndrome (AIDS). We report two brothers with hemophilia and human immunodeficiency virus (HIV) exposure who developed porphyria cutanea tarda. These brothers are heterosexual, have familial porphyria cutanea tarda, and developed overt familial porphyria cutanea tarda in their early twenties. One brother's symptoms were provoked by attending an ultraviolet A suntanning parlor. Our two patients, unlike the previously reported three patients, have not developed AIDS, though one patient has evidence of defective cell-mediated immunity. Three of the five cases of porphyria cutanea tarda associated with HIV infection involved familial porphyria cutanea tarda. It now may be advisable to order HIV serology tests in patients who have porphyria cutanea tarda. We recommend that HIV-positive individuals avoid ultraviolet A radiation because of its immunosuppressive effects in persons already at risk of immunosuppression. Such exposure is further contraindicated in those individuals with porphyria cutanea tarda.

A 42 year old heterosexual male with symptomatic human immunodeficiency virus infection presented with a 2-week history of tense blistering skin lesions following azidothymidine therapy. Urinary porphyrin excretion confirmed the diagnosis of porphyria cutanea tarda. The blisters resolved following the withdrawal of the drug but recurred when rechallenged. Three other cases of porphyria cutanea tarda, not associated with azidothymidine, who subsequently developed acquired immunodeficiency syndrome have recently been described. If azidothymidine is not the precipitating agent, it is possible that human immunodeficiency virus itself can impair porphyrin metabolism, leading to the clinical and biochemical features of porphyria cutanea tarda.

Several recent reports have described an association between human immunodeficiency virus (HIV) infection and porphyria cutanea tarda (PCT). We describe two HIV-infected patients who developed PCT and review 29 other reported cases of coexistent PCT and infection due to HIV. Recognized porphyrinogenic factors were identified in our patients and in 27 of the 29 cases described in the literature. Even in the two cases that lacked obvious precipitant factors for PCT, the possibility of hepatitis C was not excluded. This fact suggests that the co-occurrence of PCT and infection due to HIV may reflect the coexistence of risk factors for the two diseases rather than a causal association. Despite concern that exposure to sulfonamides might exacerbate porphyria, one of our patients and three patients described in the literature were safely treated with sulfonamides.

Recently, cases of porphyria cutanea tarda (PCT) have been reported associated with infection due to human immunodeficiency virus (HIV). We presented the cases of three males, former ethanol users, and which have had previously a contact with the Hepatitis B virus. In one of the patients symptomatology appeared after treatment with zidovudine was begun. We suggest that HIV infection associated with other toxic or viral factors could contribute to the early development of a PCT latent until that moment.
