Cutaneous T-cell lymphoma, tropical spastic paraparesis, cerebral vasculitis, and protein S deficiency in a patient with HTLV-I

[Vasculitis associated with viral infections]

VIRUSES, THE CAUSE OF VASCULITIS: Although the majority of systemic vasculitis are of unknown causes, the responsibility of a viral infection has been formally demonstrated in some of them and specific treatment can permanently cure them. Each virus incriminated accounts for a particular type of vasculitis. HEPATITIS B VIRAL INFECTION (HBV): Is the cause of polyarteritis nodosa in 36 to 50% of cases. The onset of the symptomatology is acute, usually within a few months following the infection; it is comparable to that observed in the absence of HBV infection. CRYOGLOBULINEMIA RELATED TO THE HEPATITIS C VIRUS (HCV): The clinical manifestations are those of systemic vasculitis with particular tropism for the skin (involvement generally inaugural and almost constant), peripheral nerves and the glomerula. They occur fairly late during the infection. VASCULITIS ASSOCIATED WITH HIV INFECTION: There is strong tropism for the peripheral (multi-neuritis) and central nervous system. During acute parvovirus B19 infection Vasculitis lesions have occasionally been reported following the viremic phase, generally limited to one or several flares of vascular purpura predominating on the lower limbs. FOLLOWING VARICELLA-HERPES ZOSTER INFECTION: Vasculitis occasionally develops in the form of a central neurological deficiency (locomotor deficiency with or without aphasia around one month after an ophthalmologic herpes zoster) or involving the retina or, more rarely, the skin or the kidneys. VASCULITIS ASSOCIATED WITH CYTOMEGALOVIRAL INFECTION: Predominantly observed in immunodepressed patients, vasculitis after CMV infection is diffuse and basically involving the digestive tube, notably the colon, the central nervous system and the skin. A RARE COMPLICATION OF AN HTLV1 INFECTION: Vasculitis of the retina often in the form of necrotic retinitis is often associated with spasmodic paraparessia.

THERAPEUTIC STRATEGY

For many vasculitis of viral origin, corticosteroid and immunosuppressive treatments are only indicated in second intention following failure with antiviral agents and the combination of antivirals and plasma exchanges.

Extracorporeal photochemotherapy alone or with adjuvant therapy in the treatment of cutaneous T-cell lymphoma: a 9-year retrospective study at a single institution

BACKGROUND

Extracorporeal photochemotherapy (ECP; photopheresis) is a treatment option for cutaneous T-cell lymphoma (CTCL).

OBJECTIVE

This study describes the outcomes obtained with ECP alone or with adjuvant therapy in treating CTCL.

METHODS

A 9-year retrospective study was performed at a single institution.

RESULTS

Among 69 patients, 37 were treated with 6 months or more of ECP alone over an average of 36.9 months. Of these patients, 68% (25/37) had stage T2, 5% (2/37) had stage T3, and 27% (10/37) had stage T4 CTCL. Complete response (no skin or systemic disease for 1 month or more) and partial response (50%-99% skin improvement for 1 month or more) were achieved by 14% (5/37) and 41% (15/37) of patients, respectively, giving an overall response rate of 54% (20/37). In recalcitrant patients, adjuvant therapy significantly increased the response rate from 31% (4/13) to 69% (9/13) (P = 0.004). ECP was well tolerated in the entire patient population.

CONCLUSION

Response rates in this study compared favorably with those in previous studies, underscoring the potential value of ECP in treating CTCL. To our knowledge, this investigation included the largest group of CTCL patients ever treated with ECP at a single institution.
