Atypical acute graft-versus-host disease

Acute graft-versus-host disease (GVHD) is a life-threatening complication of allogeneic bone marrow transplantation. It is important to recognize the dermatologic manifestations of acute GVHD, as skin is often the initial organ of involvement. We present a case of acute GVHD characterized by rare clinical and histopathologic findings as only two erythematous nodules clinically and abrupt follicular wall necrosis histopathologically.     

Acute graft-vs-host disease. Development following autologous and syngeneic bone marrow transplantation

Graft-vs-host disease (GVHD) is a frequent complication of allogeneic bone marrow transplantation but has been infrequently reported following autologous or syngeneic bone marrow transplantation. Ninety-six autologous and 19 syngeneic marrow transplants were performed at our institution between July 1977 and March 1984. We report acute cutaneous GVHD occurring in seven patients who received autologous marrow and two patients who received marrow from an identical twin. All nine patients had clinically detectable eruptions and had skin biopsy specimens with histologic changes of grade 2 acute GVHD. Although most cases were mild and self-limiting, four patients required systemic corticosteroids to treat their disease. Thus, acute cutaneous GVHD was seen in approximately 8% of patients receiving autologous or syngeneic bone marrow transplants at our institution.     

PUVA therapy for chronic cutaneous graft-vs-host disease

Chronic graft-vs-host disease (GVHD) is an immunologic disorder frequently occurring as a late sequelae of allogeneic bone marrow transplantation and characterized in the skin with lichenoid or sclerodermoid lesions. Systemic immunosuppressive agents such as corticosteroids or cyclosporine are usually required to control the disease. Therapy with psoralen and UVA (PUVA) has recently been shown to be effective for skin and oral mucosa in a few cases of GVHD. We present our experience with PUVA in six patients, five with lichenoid and one with sclerodermoid GVHD. None of these patients had significant systemic involvement. All five patients with lichenoid GVHD showed clinical improvement after PUVA therapy. Three of these patients had complete clearance of skin lesions. Clinical clearance of the disease was accompanied by microscopic clearance. The patient with sclerodermoid GVHD did not respond to therapy. No significant complications or exacerbation of systemic disease occurred. We confirm that PUVA is an effective and safe therapy for the cutaneous manifestations of lichenoid chronic GVHD. We postulate that PUVA therapy clears chronic lichenoid GVHD by selective cytotoxicity for the activated lymphoid cells in the inflammatory infiltrate.     

Role of skin biopsy to confirm suspected acute graft-vs-host disease: results of decision analysis

OBJECTIVE: To estimate the value of skin biopsy in the evaluation of suspected acute cutaneous graft-vs-host disease (GVHD) after allogeneic stem cell transplantation. DESIGN: Decision analysis using parameters specified by expert opinion for skin biopsy characteristics, prevalence of acute GVHD, and value of potential outcomes. One-, 2-, and 3-way sensitivity analyses were performed. SETTING: Major stem cell transplantation centers in the United States. PATIENTS: Hypothetical cohort of patients with suspected acute cutaneous GVHD after stem cell transplantation. INTERVENTIONS: The following 3 interventions were compared: treat immediately for GVHD without performing a skin biopsy, perform a skin biopsy and treat immediately but stop treatment if skin biopsy specimen findings are inconsistent with GVHD, and perform a skin biopsy and await results of the skin biopsy specimen before treating. MAIN OUTCOME MEASURES: Number of patients appropriately and inappropriately treated with each intervention, consistency of physician-reported behavior, individualized decision analyses, and preferred intervention based on the aggregate estimates of respondents. RESULTS: The decision to treat immediately for GVHD without performing a skin biopsy yielded the best clinical outcome for the specified clinical setting and under the parameters specified by expert opinion. One-way sensitivity analyses showed that these conclusions are robust if the prevalence of acute cutaneous GVHD in stem cell recipients with rash is greater than 50%, if the sensitivity of skin biopsy specimen is less than 0.8, and the specificity of skin biopsy specimen is less than 0.9. Only 25% of physicians interviewed chose an intervention consistent with their estimates of prevalence, test characteristics, and outcome evaluations, indicating an opportunity to improve management of this important clinical condition. CONCLUSIONS: This decision analysis modeling technique predicts that in patient populations in which the prevalence of GVHD is 30% or greater (typical for allogeneic stem cell transplantation), the best outcomes were obtained with treatment for GVHD and no skin biopsy. In populations with prevalence of GVHD of 30% or less, obtaining a skin biopsy specimen to guide treatment was predicted to provide the best patient outcomes.     

Clinical significance of skin biopsies in the diagnosis and management of graft-vs-host disease in early postallogeneic bone marrow transplantation

OBJECTIVE: To determine the value of skin biopsies in the management of suspected graft-vs-host disease (GVHD) within 30 days of allogeneic bone marrow transplantation (BMT). DESIGN: Retrospective study based on review of a BMT database. SETTING: Leukemia/BMT ward of a tertiary care, university teaching hospital. PATIENTS: One hundred and eighty-seven consecutive patients who received allogeneic BMT between January 1, 1994, and June 30, 1997, at Vancouver General Hospital, Vancouver, British Columbia. MAIN OUTCOME MEASURES: (1) Skin biopsy frequency for patients with rashes suggestive of acute GVHD; (2) clinical significance of skin biopsy in the management of patients with suspected acute GVHD after BMT; (3) relationship between severity of clinical GVHD and the likelihood to receive GVHD therapy; and (4) relationship between biopsy status or biopsy result and outcome of BMT (acute and chronic GVHD, transplant-related mortality, and overall and event-free survival). RESULTS: During the early post-BMT period (<30 days after BMT), 88 patients had rashes suggestive of acute GVHD; of these, 51 (58%) underwent skin biopsy to confirm the diagnosis. Skin biopsies were performed more often for higher clinical stages of cutaneous GVHD. There was no significant difference between the patients with positive biopsy findings and those with negative findings, either in the clinical severity of acute GVHD or in likelihood to receive treatment for GVHD. Most (85%) of the patients who underwent biopsies and received GVHD therapy had treatment initiated before skin biopsies were performed or before the results were available. The higher the clinical grade of overall acute GVHD, the more likely it was that the patients were treated for GVHD (P<.001). The outcome of BMT was not influenced by the skin biopsy status or biopsy result. CONCLUSIONS: The biopsy findings correlated poorly with the clinical severity of skin rash suggestive of acute GVHD soon after BMT. The decision to treat suspected acute GVHD depended not on skin biopsy findings but rather on clinical severity of acute GVHD. In this regard, skin biopsy has a limited role in the management of patients early after allogeneic BMT.     

Late appearance of acute graft-vs-host disease after suspending or tapering immunosuppressive drugs

BACKGROUND: Graft-vs-host disease (GVHD) is divided into acute and chronic phases based on time and clinical and histological features. The criterion of 100 days after transplantation for separating acute GVHD from chronic GVHD has been challenged on the following points: (1) the lichenoid rash of chronic GVHD may be observed as early as day 31 and acute GVHD may persist after day 100 in some cases, and (2) specific histological features do not consistently separate acute from chronic GVHD defined as the number of days after transplantation. However, the appearance of acute cutaneous GVHD after day 100 is not well established. OBSERVATIONS: Three patients developed a rash with clinical and histological features of acute GVHD between days 153 and 192 after allogeneic bone marrow transplantation or peripheral blood stem cell transplantation. In all patients, the late flare of acute GVHD occurred after tapering or suspending the immunosuppressive regimen with cyclosporine or corticosteroids, and was accompanied by stigmata of chronic GVHD in other target organs. CONCLUSIONS: The rash of acute GVHD may be observed as late as 192 days after transplantation, especially after tapering or suspending the immunosuppressive drugs, and should be considered in the differential diagnosis of late erythematous eruptions after transplantation.     

Lesiones ampollosas como forma de presentación de una enfermedad de injerto contra huésped crónica

Graft-vs-host disease is still the leading cause of morbidity and mortality in patients undergoing bone marrow transplantation. It is important to start treatment early to reduce the severity and consequences of this complication. Cutaneous lesions are often the presenting compliant of graft-vs-host disease and presage visceral involvement.We present the case of a 45-year-old woman with multiple myeloma who underwent autologous and subsequently allogeneic bone marrow transplantation with hematopoietic precursors. She developed bullous lesions with fluid elimination on the abdomen and legs. Biopsy findings were compatible with graft-vs-host disease and immunosuppressive therapy was increased. She subsequently presented oral lichenoid lesions and sicca syndrome. The bullous lesions progressed to painful ulcers that healed leaving highly sclerodermatous skin with substantial hyperpigmentation.Bullous lesions are a rare form of presentation of chronic graft-vs-host disease. In such cases, the diagnosis may not be suspected initially, particularly when the lesions are isolated and internal organs are not involved.     

Histochemical and ultrastructural study of diffuse melanoderma after bone marrow transplantation

Summary Hyperpigmentation is a well-recognized feature of cutaneous graft-versus-host disease (GVHU). and is usually restricted to sites where lichenoid or sclerodermiform lesions have occurred. Since 1975, two of 745 patients treated by allogeneic bone marrow transplantation in our institution have developed diffuse melanoderma which differed considerably from the classic presentations. They both developed acute GVHD. then lichen planus-like chronic lesions and diffuse melanoderma. Histology of biopsies of the pigmented skin showed intense pigment deposition in the basal and suprabasal layers, and in dermal macrophages. On split-dopa, melanocyte counts were 98 and 93 per Held, respectively. Electron microscopy showed melanocytes protruding into the dermis, and dark melanosomes in all epidermal layers and in macrophages. These findings were suggestive of post-inflammatory hyperpigmentation. In bone marrow recipients, de nova melanoderma is a rare event which could represent a feature of cutaneous GVHD in pigmented subjects.     

Analysis of risk factors for acute cutaneous graft-versus-host disease after allogeneic stem cell transplantation

BACKGROUND: Although skin is typically the first site of involvement of acute graft-versus-host disease (GVHD), most standard recommended staging and grading criteria allow enrolment of patients with involvement of GVHD target organs other than the skin in studies analysing risk factors for acute GVHD after stem cell transplantation (SCT). OBJECTIVES: To determine the risk factors for developing histologically confirmed acute cutaneous GVHD in patients who underwent allogeneic SCT for different haematological disorders. METHODS: This retrospective study was based on review of clinical files and databases from 300 consecutive patients with several haematological disorders who received allogeneic SCT between 1 January 1984 and 31 December 1999 at Hospital Universitario de la Princesa, Madrid, Spain. Variables evaluated included diagnosis of haematological disorder, age and gender (donor and recipient), HLA matching, female donor to male recipient, donor and recipient viral serology (cytomegalovirus), conditioning regimen, GVHD prophylaxis, blood counts at day of engraftment, mortality, cause of death, and survival at 100 days, 5 years and 10 years following SCT. RESULTS: In multivariate analysis, risk factors for acute cutaneous GVHD were type of haematological disease (P = 0.006), HLA disparity (P = 0.006), number of transplants per patient (P = 0.017), conditioning regimen (P = 0.001), and GVHD prophylaxis (P = 0.025). Survival rates did not differ significantly for cases and controls. CONCLUSIONS: Risk factors for acute cutaneous GVHD were a diagnosis of chronic myeloid leukaemia, HLA disparity, receipt of more than one SCT, conditioning regimens including total body irradiation, and GVHD prophylaxis regimens other than ciclosporin plus methotrexate. Other common risk factors for acute GVHD without specific target organ involvement showed no significant association with the risk for developing acute GVHD affecting the skin as primary target organ.     

Chronic Graft-versus-Host Disease with Follicular Involvement

The clinical and histopathological findings in a 25-year-old Japanese male patient who suffered from chronic graft-versus-host-disease (GVHD) with follicular involvement are described. The patient had been diagnosed as aplastic anemia and underwent an allogeneic bone marrow transplant (BMT). In the eighth month thereafter, pruritic follicular red papules developed over his trunk and extremities. A biopsy specimen revealed histological exocytosis of lymphocytes into the hair follicles and basal-cell vacuolization of the follicular epithelium. Analysis of T-lymphocyte subpopulations in the dermis revealed a predominance of CD4 positive cells. To our knowledge, several cases of acute follicular GVHD have been reported (1, 2); however, the occurrence of chronic GVHD with follicular involvement (chronic follicular GVHD) has not been clearly documented.     

Clinical manifestations of cutaneous graft-versus-host disease after allogeneic haematopoietic cell transplantation: long-term follow-up results in a single Turkish centre

The aim of this study was to evaluate the clinical manifestations of cutaneous graft-versus-host disease (GVHD) developed after allogeneic haematopoietic cell transplantation. In all, 67 patients were evaluated: 49 patients developed acute GVHD, 17 patients developed de novo chronic GVHD and 29 developed secondary chronic (15 limited, 14 progressive) GVHD following acute cutaneous GVHD. Of the 46 patients with chronic GVHD, lichenoid lesions were observed in 32 and sclerodermoid lesions were observed in 12. In four patients with sclerodermoid cutaneous GVHD, these lesions occurred after a lichenoid phase. Oral lesions were present in 61% of the patients and six of them had only oral mucosal involvement without any skin lesions. Nail lesions were observed in 31% of the patients. During the follow-up period 15 patients with GVHD died and in 7 of them the cause of death was related to chronic GVHD. In conclusion, GVHD has a wide spectrum of cutaneous manifestations, which can be used as an important tool for the early diagnosis of the disease.     

Eczematoid graft-vs-host disease: a novel form of chronic cutaneous graft-vs-host disease and its response to psoralen UV-A therapy

BACKGROUND: Chronic cutaneous graft-vs-host disease (GVHD) is generally classified by whether lesions have a lichenoid or sclerodermatous morphology. Other unusual clinical forms have been reported that exhibit the features of dermatomyositis and lupus erythematosus. Within a large population of individuals who underwent allogeneic stem cell transplantation because of hematologic malignancy, a group of patients was identified in whom severe and persistent eczema developed. OBSERVATIONS: We prospectively evaluated 10 adult patients with unexplained eczematous dermatosis after allogeneic hematopoietic stem cell transplantation. The dermatosis developed between 2 and 18 months (mean, 7.5 months) after receipt of the transplant, exhibited the typical clinical features of dermatitis, and became erythrodermic in each case. The patient group had strong risk factors for chronic cutaneous GVHD: 8 had received a transplant from an unrelated donor, 7 had evidence of extracutaneous GVHD, and 7 had a history of acute cutaneous GVHD. Sampling of lesional skin revealed the histologic features of GVHD coexisting with the changes of dermatitis. The patients were treated with topical corticosteroid and systemic immunosuppressive agents. Six patients also received psoralen-UV-A. Four patients achieved prolonged remission. Six patients died, 5 of infective complications and 1 of relapsed leukemia. CONCLUSIONS: The eczematous dermatosis observed represents a novel form of chronic cutaneous GVHD that we named eczematoid GVHD. Eczematoid GVHD is an aggressive, chronic dermatosis that requires substantial immunosuppression therapy to achieve control. It is associated with a poor prognosis. Although atopy can be transmitted to an individual from a hematopoietic stem cell transplant, none of the donors in this series gave a history of an atopic disorder. Therefore, other factors must be implicated in provoking the expression of an eczematous phenotype in individuals with underlying chronic graft-vs-host activity.     

Acute follicular graft-versus-host disease.

We documented by clinical, histopathologic and immunohistochemical analysis a case of acute follicular graft-versus-host disease (GVHD), in which an erythematous-to-violaceous follicular papular eruption constituted the major clinical pattern of cutaneous involvement. Although acute follicular GVHD is rare, it is important to recognize it as an early skin manifestation of acute cutaneous GVHD allowing prompt therapy.     

Lichenoid graft vs. host disease following liver transplantation

BACKGROUND: Graft vs. host disease (GVHD) is a common complication of bone marrow transplantation (BMT) but is rarely seen after solid organ transplantation. METHODS: We report a case of lichenoid GVDH arising in a 60-year-old man 10 weeks after orthotopic liver transplantation. RESULTS: Skin biopsies revealed changes suggestive of lichenoid GVHD, but histological features differed from those described in post bone marrow (stem cell) transplant GVHD, in that a dense lymphoid infiltrate was present. The brisk infiltrate contained eosinophils that initially led to concern for a lichenoid drug eruption. The patient developed multiorgan GVHD after reduction in immunosuppression. The diagnosis of chronic GVHD was confirmed by the demonstration of chimerism in the patient's peripheral blood. The generalized cutaneous eruption and systemic manifestations responded to salvage therapy including intravenous immunoglobulin infusion, increased immunosuppression with high-dose steroids, mycophenolate mofetil, and systemic and topical tacrolimus. CONCLUSIONS: In interpreting skin biopsies, it is important to recognize that brisk inflammation may be seen in GVHD in the setting of solid organ transplantation, in contrast to the more sparse inflammation typical of GVHD following BMT. The clinical and histologic differential diagnosis included the eruption of lymphocyte recovery, drug reaction, and viral exanthem. We provide a conceptual framework for evaluating generalized cutaneous changes that may occur post transplantation.     

Chronic cutaneous sclerodermoid graft-versus-host disease: evaluation by 20-MHz sonography

BACKGROUND: Chronic graft-versus-host disease (GVHD) is an immunological disorder frequently occurring as a late consequence of allogeneic bone marrow transplantation. Two variants, cutaneous lichenoid and sclerodermoid, have been described, based on clinical and histopathological examinations. It is, however, difficult to determine non-invasively the degree of cutaneous GVHD in vivo. Ultrasonographic methods have recently provided us with the means for objective and non-invasive monitoring of the dynamics of many chronic skin diseases. AIM, PATIENTS AND METHODS: In five patients with chronic cutaneous sclerodermoid GVHD skin thickness was measured with a 20-MHz B-mode ultrasound scanner (DUB 20S, taberna pro medicum, Lüneburg, Germany) in a clinically well-defined target skin lesion. Additionally cutaneous GVHD was assessed histologically before and after treatment. RESULTS: In all patients before treatment the corium of sclerotic skin was thicker than the corresponding areas of healthy skin. The skin thickness was increased from 45% to 83%. In the subcutaneous tissue proper echo-rich reflexes were prominent, representing the correlate of subcutaneous fibrotic trabeculae. In all patients ultrasonographic evidence of regression was shown (decrease of skin thickness by 18-83%). Moreover, it was demonstrated that quantitative assessment of skin thickness is feasible. CONCLUSIONS: In this paper we describe the detailed sonographic features of cutaneous sclerodermoid GVHD for the first time. As the method is simple and non-invasive, repeated examinations are possible. This provides the basis for monitoring treatment effects and efficient follow-up in these chronically progressive clinical conditions after bone marrow transplantation.     

Psoralen plus ultraviolet-A-bath photochemotherapy as an adjunct treatment modality in cutaneous chronic graft versus host disease

BACKGROUND: Cutaneous chronic graft versus host disease (GVHD) is a severe complication following allogeneic stem cell (PBSCT) and bone marrow transplantation (BMT). Immunosuppressive therapy consists of prednisone, cyclosporine-A, azathioprine or mycophenolate mofetil (MMF). Treatment of patients refractory to immunosuppression represents a major problem. METHODS: We report six patients suffering from severe chronic GVHD of the skin who did not respond to immunosuppressive therapy or relapsed after reduction of glucocorticosteroids. Patients were treated with psoralen plus ultraviolet (PUVA)-bath photochemotherapy three times weekly following a standardized treatment protocol under continued treatment with prednisone and/or MMF. One patient was additionally pretreated with ultraviolet-A1 (UV-Al). RESULTS: After a median of 14, 5 treatment sessions, skin lesions improved. Out of six patients, three showed a complete remission. In all patients, systemic immunosuppressive therapy could be reduced. In sclerodermic lesions, skin thickness returned to the levels of normal skin after 25 treatments confirmed by 20 MHz ultrasound evaluation. In a follow-up ranging from 2 to 21 months (median 10, 3 months), skin conditions remained stable. CONCLUSION: Psoralen plus ultraviolet-A-bath represents an effective adjunct treatment option for extensive chronic and sclerodermic cutaneous GVHD offered by dermatologists. This is of high interest in patients suffering from cutaneous GVHD resistant to conventional immunosuppressive therapy and should be included to the menu of topical treatment options for chronic cutaneous GVHD.     

Two cases of transfusion-associated graft-vs-host disease after open heart surgery.

BACKGROUND--Some cases of blood transfusion-associated (TA) graft-vs-host disease (GVHD) in immunocompetent patients have been reported, but those dermatologic findings were not precisely mentioned. We describe patients with clinicopathologically TA-GVHD and compare TA-GVHD and acute GVHD after bone marrow transplantation. OBSERVATIONS--Two cases of TA-GVHD after open heart surgery are reported. In both immunocompetent patients, severe erythema multiformelike skin rash developed over the entire body, followed by fever, diarrhea, jaundice, transaminitis, pancytopenia, and marrow alpasia approximately 10 days after operation. The rash in one patient changed from erythema multiformelike to toxic epidermal necrolysis at death. Skin biopsy specimens revealed eosinophilic bodies, basal vacuolation, and exocytosis in the epidermis. Eosinophilic bodies tend to appear in the upper epidermis. Immunohistochemistry studies revealed that infiltrating cells were CD4 and CD8. While acute GVHD in immunosuppressed patients who have undergone bone marrow transplantations often shows lichenoid histologic features, TA-GVHD in our patients who were immunocompetent may resemble severe erythema multiforme or toxic epidermal necrolysis. The difference in TA-GVHD may be related to lack of host modification by immunosuppression. CONCLUSIONS--Irradiation of the blood products should be required in open heart surgery, for TA-GVHD in immunocompetent patients is almost always fatal.

Cutaneous graft-versus-host reaction: prognostic features seen by light microscopy

Acute graft-versus-host disease (GVHD) is a severe complication of bone marrow transplantation. The diagnosis may be made and its course followed by serial skin biopsies. The degree of epidermal change has been used as a guideline in grading each biopsy, but great variation may be found within each grade, especially grade 2 (basal cell vacuolization and dyskeratosis). To find a histologic parameter that is prognostic of more severe acute GVHD, we examined retrospectively the serial biopsies of 54 patients. When we studied early cutaneous graft-versus-host reaction (GVHR), represented by the grade 2 biopsies, the number of dermal and epidermal mononuclear inflammatory cells correlated positively with the probability of developing more severe acute GVHD. In addition, the patients who had more severe acute GVHD tended to have an earlier appearance of cutaneous histologic changes. None of the other histologic parameters examined in these grade 2 biopsies were found to be predictive of GVHD progression. In addition, no histopathologic parameters in these grade 2 biopsies were predictive of the subsequent development of chronic GVHD.
