Case report: post-transfusion purpura.

Post-transfusion purpura (PTP) is a rare disorder characterized by the abrupt onset of severe thrombocytopenia following a blood transfusion. We describe a case of PTP in a patient treated with plasmapheresis, noting that this is an uncommon but treatable disease entity.

Varicella hepatitis: a fatal case in a previously healthy, immunocompetent adult. Report of a case, autopsy, and review of the literature.

Varicella, usually a benign infection of childhood, is known to be associated with more serious complications, especially in adults and immunocompromised patients. Of these, varicella pneumonitis is the most common. Primary varicella hepatitis has been described, though rarely, in immunocompromised patients. We present a case of a previously healthy human immunodeficiency virus-negative 26-year-old immigrant from El Salvador in whom primary varicella developed that rapidly progressed to fulminant hepatic failure, disseminated intravascular coagulation, and death. Autopsy revealed evidence of varicella in the liver, adrenal glands, and myometrium. To our knowledge, this is the first report of a fatal case of varicella hepatitis in a previously healthy, immunocompetent patient.

Control of polycythaemia vera with photochemotherapy in a patient with cutaneous T-cell lymphoma.

We report the use of photochemotherapy in a patient with polycythaemia vera (PV) and cutaneous T-cell lymphoma (CTCL). The patient was diagnosed with PV and required monthly phlebotomy. Subsequently he was diagnosed with CTCL and was started on photochemotherapy. A clinical improvement in both conditions, with haematocrit stabilizing at a level of 50%, eliminated the need for further phlebotomy. It is conceiveable that photochemotherapy induced the clinical and laboratory improvement in PV by targeting the aberrant clonal haemopoietic cell, similar to the mechanism thought to be operative in CTCL, a clonal helper T cell malignancy.

Hair transplant by incisional strip harvesting.

The art of hair transplantation has continued to develop, achieving surgical correction with an enhanced aesthetic outcome. We have used incisional harvesting with donor site closure and have found that incisional harvesting allows for much more latitude in choosing slit, strip, micro, mini, or the standard round or square punch technique.

Extracorporeal photochemotherapy in progressive systemic sclerosis.

BACKGROUND: Extracorporeal photochemotherapy, an immune-modulating form of therapy, has been shown to be effective in the treatment of autoimmune diseases. We evaluated the effects of extracorporeal photochemotherapy in the treatment of patients with progressive systemic sclerosis (PSS). METHODS: Nine patients with active progressive systemic sclerosis were treated with extracorporeal photochemotherapy on 2 successive days monthly. The duration of therapy ranged from 6 to 21 months. RESULTS: A significant improvement was noted in the skin, musculoskeletal system, functional index, and symptoms including Raynaud's phenomenon, dyspnea, fatigue, dysphagia, and arthralgias, as well as improvement of cutaneous ulcers. Stabilization of the pulmonary function studies was also noted in the majority of patients over the course of therapy. No serious side effects were noted throughout the course of therapy in the 9 patients. CONCLUSIONS: The results suggest that photopheresis may be beneficial in selected early cases of progressive systemic sclerosis.

Extracorporeal photopheresis in the treatment of AIDS-related complex: extended trial.

The objective of this study was to further evaluate the relative safety of extracorporeal photopheresis in the treatment of patients with AIDS-related complex. Twenty patients with AIDS-related complex, three from the initial report and 17 additional patients, were enrolled. The patient population had various risk factors. There were nine homosexuals, five heterosexual consorts of human immunodeficiency virus (HIV)-positive patients, four reformed i.v. drug abusers, and two hemophilia patients. The patients received monthly treatment with extracorporeal photopheresis. In 16 of the 19 patients, this study provides evidence of clinical stability over a longer period. The relative stability of beta 2-microglobulin and neopterin levels demonstrates that photopheresis therapy does not have an untoward effect on the degree of activation of the immune system with respect to induction of HIV replication. Antibody titers to the major viral antigens, envelope glycoproteins (gp) 120 and 41, reverse transcriptase enzyme gp 66/31 and 55, and the core protein p24 remained stable throughout the course of therapy. A subjective improvement was noted in the majority of patients. The evaluation of T-cell subsets revealed that the photopheresis treatment did not have a detrimental effect on CD3 and CD8 cells. Some decreases were noted in the CD4 cell counts but the decline may be less than is normally seen at corresponding stages of HIV infection. Skin test responsivity improved in 11 patients, remained unchanged in seven patients, and declined in two. The preliminary results suggest that in HIV disease, extracorporeal photopheresis is safe and warrants a prospective controlled trial.

Viral-specific immunization in AIDS-related complex by photopheresis.

The potential for therapeutic intervention in 7 patients with AIDS-related complex (ARC) was evaluated through the use of photopheresis. The rationale for the study was based on: 1. the demonstration that psoralen and UVA could inactivate HIV/virus in vitro; 2. CD4 cells are the primary target population effected by HIV and photopheresis; and 3. reinfusion of inactivated virus and cell-associated virus might serve to engender an immune response. Preliminary results in 7 patients with ARC over 6 to 18 months revealed a virus-specific response with an elevation of HIV antibodies, while EBV and CMV titers remained unchanged. The immunologic results revealed an increase in the CD8 lymphocyte population, stable activation markers (B2 microglobulin neopterin), a decrease in p24 antigen titers and inability to culture HIV virus in 3 patients. All of these results were in the context of a stable or increasing CD4+ percent. Six patients did not reveal a generalized inhibition of other immune responses as demonstrated by recovery of DTH. In addition, the resolution of lymphadenopathy, night sweats, fever and weight loss, paralleled the immunologic response.

Production of hydrogen peroxide by cutaneous T-cell lymphoma following photopheresis with psoralens and ultraviolet light.

Treatment of peripheral blood mononuclear cells with 8-methoxypsoralen (8-MOP) and ultraviolet light, a procedure known as PUVA, has been found to be useful in the management of systemically disseminated cutaneous T-cell lymphoma (CTCL). In the present study we used a highly sensitive flow cytometric assay in conjunction with the hydroperoxide-sensitive dye 2',7'-dichlorofluorescein diacetate to measure intracellular hydrogen peroxide in normal lymphocytes and CTCL following PUVA treatment. Based on their laser light-scattering properties, lymphocytes were separated into three major subpopulations. We found that ultraviolet light alone caused an increase in the hydrogen peroxide content of each of the subpopulations, a response that was augmented when the cells were pretreated with 8-MOP (50 ng/ml). Cells from CTCL patients were more sensitive to the effects of 8-MOP than were normal lymphocytes. In both cell types, the production of hydrogen peroxide was found to be inhibitable by catalase. We noted an increase in hydrogen peroxide production following photopheresis; however, this was observed only 24 h after treatment. In addition, a further increase in hydrogen peroxide production was observed in lymphocytes isolated from peripheral blood that had been obtained from patients at 15 min after a second photopheresis treatment. Hydrogen peroxide is known to modulate the action of cytokines as well as the immunological responses of leukocytes. Our data suggest that the production of hydrogen peroxide by lymphocytes may be important in the action of PUVA in CTCL.

Extracorporeal photopheresis in the treatment of AIDS-related complex: a pilot study.

OBJECTIVE: To determine side effects of extracorporeal photopheresis in the treatment of patients with the acquired immunodeficiency syndrome (AIDS)-related complex, and to gain early evidence of efficacy of the treatment. DESIGN: Uncontrolled trial. SETTING: Tertiary referral center. PATIENTS: Five patients with AIDS-related complex: three homosexual men and one man and one woman with histories of intravenous drug abuse. One patient, a homosexual man, withdrew from therapy after 5 months but returned for monthly clinical and laboratory evaluations. INTERVENTION: Monthly treatments with extracorporeal photopheresis. MEASUREMENTS AND MAIN RESULTS: Symptoms resolved in four patients. Lymphadenopathy disappeared in all five. Four patients had delayed-hypersensitivity reactions to skin testing (as defined by the Walter Reed staging classification). All showed increases in p24 and gp120 antibody levels. The CD4-cell percentage increased in four patients and declined in one after 6 months of therapy, but the absolute CD4 count decreased in two patients. At 15 months, the CD4 percentage remained at or increased over the baseline value in three patients still in the study but decreased in one. Levels of Beta 2-microglobulin decreased or remained stable in four patients. All patients were culture positive for the human immunodeficiency virus (HIV) before treatment. One patient had a negative viral culture after 5 months of treatment with confirmation. Two other patients became HIV culture negative, one at 14 and one at 15 months: The former patient became positive at 15 months and the latter patient remained negative at 16 months. CONCLUSIONS: The preliminary results suggest that extracorporeal photopheresis deserves further evaluation as therapy for AIDS-related complex.

Photopheresis for the treatment of cutaneous T cell lymphoma.

We investigated the use of extracorporeal chemotherapy (photopheresis) in eight patients with cutaneous T cell lymphoma. Initially described by Edelson et al. for the treatment of erythrodermic cutaneous T cell lymphoma, we have expanded the treatment to include patients with extensive patch/plaque disease as well as tumor-stage disease. Four of five patients with erythrodermic stage disease had either a complete or a partial clinical remission with photopheresis alone. One patient with extensive patch/plaque disease continued to have a partial clinical remission of 7 months' duration with photopheresis alone. Of the two patients with tumor-stage disease, one remained without evidence of clinical disease at 10 months with photopheresis alone, whereas the second patient had a partial clinical remission of 5 months with a combination of local radiation therapy followed by monthly photopheresis. The skin biopsy specimen obtained from the patient with tumor-stage disease in complete clinical remission did not show cutaneous T cell lymphoma. We conclude that photopheresis is an effective modality alone or in combination with adjunctive therapy for erythroderma, extensive patch/plaque disease, and some tumor-stage disease.
