Autologous marrow recovery following allogeneic marrow transplantation in a patient with severe aplastic anemia

A 45-year-old woman with severe idiopathic marrow failure was prepared for marrow transplantation by administration of cyclophosphamide (cy) 50 mg/kg on each of four successive days. She then received an intravenous infusion of 20 X 10(9) nucleated marrow cells from an HL-A matched and mixed lymphocyte culture (MLC) non-reactive sister. There was evidence for minimal marrow recovery in 1-2 months and a second marrow infusion was carried out 69 days after the first without additional immunosuppression. There was a continued slow recovery of peripheral blood counts with complete reconstitution of erythropoiesis, return of the white blood cell count to between 3 and 4000/mm3, with 50% granulocytes, and platelets to 60--70,000/mm3, 11 months after the initial grafting attempt. Red cell antigens and gamma globulin allotypes were of recipient type. The MLC and the indirect cell mediated lympholysis (CML) test became positive possibly indicating cellular sensitization to non HL-A antigens. This report of a patient with severe marrow failure documents autologous recovery of marrow function after receiving a large dose of cy and allogeneic marrow. The implications of this are discussed.     

Spontaneous pneumomediastinum in a patient with bronchiolitis obliterans after bone marrow transplantation

After allogeneic bone marrow transplantation for chronic myelogenous leukemia, spontaneous pneumomediastinum and subcutaneous emphysema developed in a patient with bronchiolitis obliterans. Computed tomography scanning of the chest failed to reveal the cause. There was no evidence of a pulmonary process, pneumothorax, or pharyngeal or upper airway leak. Despite the alarming appearance of the patient, conservative management, including high-flow oxygen, resulted in resolution of the pneumomediastinum and subcutaneous emphysema. The cause of pneumomediastinum and subcutaneous emphysema in bone marrow transplant recipients is discussed.     

Cyclosporine-related encephalopathy following allogeneic bone marrow transplantation

Idiopathic granulomatous hepatitis is a rare disease of unknown cause that is characterized by recurrent fevers and granuloma in the liver. Attempts to define an exact etiology of the fever of granulomatous hepatitis frequently do not yield a precise diagnosis. Idiopathic granulomatous hepatitis was confirmed after a thorough work up and negative cultures and serologies were obtained, and in the absence of another condition that could lead to granulomas in the liver. We have experienced a 67-year-old female patient who presented with prolonged fever for 2 months and revealed granuloma in liver biopsy. She was treated with glucocorticosteroid and defervescence resulted.     

Acute renal failure following bone marrow transplantation

The medial preoptic nucleus (MPN) is an essential site for the regulation of male sexual behavior. Previous studies using c-fos as a marker for neural activation have shown that copulation increased c-fos expression in the MPN. Neural activation was also present in brain regions that are connected with the MPN and are involved in male sexual behavior, including the posteromedial bed nucleus of the stria terminalis (BNSTpm), posterodorsal preoptic nucleus (PD), posterodorsal medial amygdala (MEApd), and parvocellular subparafascicular thalamic nucleus (SPFp). The present study investigated whether the copulation-induced, activated neurons in these brain regions are involved in the bidirectional connections with the MPN. Therefore, mating-induced Fos expression was combined with application of anterograde (biotinylated dextran amine) or retrograde (cholera toxin B subunit) tracers in the MPN. The results demonstrated that neurons in the BNSTpm, PD, MEApd, and SPFp that project to the MPN were activated following copulation. However, in males that displayed sexual behavior but did not achieve ejaculation, few double-labeled neurons were evident, although both retrogradely labeled neurons and Fos-immunoreactive cells were present. In addition, retrograde neurons that expressed Fos were located in discrete subdivisions within the brain regions studied, where Fos is induced after ejaculation. Likewise, anterogradely labeled fibers originating from the MPN were not distributed homogeneously but were particularly dense in these discrete subdivisions. These results demonstrate that copulation-induced Fos-positive neurons in specific subdivisions of the BNSTpm, PD, MEApd, and SPFp have bidirectional connections with the MPN. Taken together with previous findings, this supports the existence of a discrete subcircuit within a larger neural network underlying male sexual behavior.     

Late pulmonary impairment following allogeneic bone marrow transplantation

The pulmonary function of 88 consecutive leukemic patients who had undergone allogeneic bone marrow transplantation (BMT) was studied beforehand, at 3 months, at 6 months, and annually thereafter until 5 years after grafting. The parameters for function which are indicative for obstructive and restrictive lung disease deteriorated in all patient groups during the first 3 to 6 months after BMT but partially recovered within one year. Long-term decline in lung function was similar in all patient groups, and neither the onset nor the magnitude of pulmonary dysfunction was related to the occurrence of pulmonary impairment within 6 months after grafting. Multivariate analysis was then employed to assess predictors for long-term pulmonary disease. Despite the obvious effect of chronic graft versus host disease on the course of lung function, it was in itself not a significant predictor of long-term pulmonary outcome. Rather, the conditioning regimen turned out to be indicative; compared with busulfan, fractionated total body irradiation was demonstrated to be clearly superior with a lower incidence of both restrictive and obstructive long-term lung impairment. Our data indicate a previously unknown long-term side effect of busulfan conditioning.     

Cytomegalovirus prophylaxis and treatment following bone marrow transplantation

OBJECTIVE: To provide an overview of the role of cytomegalovirus (CMV) in the bone marrow transplant (BMT) population and update the current methods of prevention and treatment of CMV infection and disease, with emphasis on CMV interstitial pneumonia (CMV-IP). DATA SOURCES: The current medical literature, including abstracts presented at recent national and international meetings, is reviewed. References were identified by searching the MEDLINE database from January 1988 through June 1994. The reference lists of the published studies and reviews obtained from the initial literature search were reviewed as well. STUDY SELECTION: Data regarding the epidemiology of CMV, the risk factor associated with CMV infection and disease, as well as data on the prevention and the treatment of CMV infection and disease in the BMT population are cited. Specific attention was focused on randomized, placebo-controlled studies pertaining to the prevention of CMV infection and disease in CMV-immunoglobulin G positive recipients undergoing allogeneic BMT. Information from nonrandomized, placebo-controlled studies was included in the absence of stronger data. DATA EXTRACTION: Information contributing to CMV in the BMT population was reviewed. Data supporting and disputing specific preventive and treatment modalities are presented. DATA SYNTHESIS: The incidence of CMV seropositivity in the general population is high and while BMT becomes a widely accepted treatment modality, CMV reactivation and subsequent disease, especially CMV-IP, becomes a significant prognostic factor of morbidity and mortality. Even though antiviral agents such as ganciclovir and foscarnet can inhibit the viral replication in vivo, they have not been able to treat CMV-IP effectively. It has been suggested that CMV-IP is an immunopathologic process that can cause irreversible damage, hence, the low efficacy of antiviral therapy and the associated high mortality. Immunomodulating agents such as intravenous immune globulin and cytomegalovirus hyperimmune globulin can increase the efficacy of antivirals in the treatment of CMV-IP. This further supports the postulated immunopathologic process of this disease. The lack of understanding of the pathophysiology of the disease compromised the efforts of treatment and led to the development of preventive interventions with antiviral and immunomodulatory regimens that resulted in a significantly lower incidence of infection and disease. As a result of current data, the Eastern Cooperative Oncology Group has published guidelines for the prevention and treatment of CMV infection and disease. CONCLUSIONS: The prognosis of CMV disease in the BMT recipients has improved as a result of a wide variety of modifications in the management of BMT recipients. These include an increased understanding of the risk factors associated with CMV infection, routine screening for CMV replication and excretion, and more effective prophylactic regimens. Still, more than half of the patients who develop pneumonia will die, indicating that more studies are needed to increase the understanding of the pathophysiology and refine the preventive and therapeutic regimens against CMV.     

Fatal eosinophilic disease following autologous bone marrow transplantation

A 15-year-old girl developed massive, fatal eosinophilic disease following autologous bone marrow transplantation (BMT) for Hodgkin's disease (HD). Prior to autologous BMT, the erythrocyte sedimentation rate (ESR) was elevated, with active HD, but eosinophilia was absent. Post-autologous BMT, ESR and peripheral eosinophilia were observed to correlate with respiratory symptoms. Initial evaluation revealed no recurrent tumor, infection or other identifiable etiology. A diagnosis of chronic eosinophilic pneumonia was made following lung biopsy. A complete response was initially achieved with steroid therapy; however, when steroid therapy was tapered, the eosinophilia and elevated ESR recurred with worsening respiratory symptoms. Terminally, severe pulmonary disease developed and recurrent HD was found in lung, lymph nodes and bone marrow. During episodes of eosinophilia, the patient's serum stimulated her bone marrow as well as control marrow to produce predominantly eosinophilic colonies. Eosinophilic colony production was not observed with patient's sera obtained prior to or during autologous BMT or with control sera. This patient died of eosinophilic inflammatory disease following autologous BMT. The etiology of this disease was not definitely identified but appeared to be due to an eosinophilic-stimulating factor which developed after autologous BMT.     

Bronchoscopic evaluation of pulmonary infiltrates following bone marrow transplantation

Mutants of human prothymosin alpha with impaired ability to inhibit yeast Saccharomyces cerevisiae. cerevisiae cell growth were characterized. Two types of prothymosin alpha-inactivating mutations were observed. Mutations that belong to the first type compromised the nuclear entry of prothymosin alpha by affecting its nuclear localization signal. Analysis of subcellular distribution of GFP-prothymosin alpha fusions revealed a bipartite nuclear localization signal that is both necessary and sufficient for nuclear import of the protein in human cells. Mutations of the second type abrogated the inhibitory action of prothymosin alpha through an unknown mechanism, without influencing the nuclear import of the protein.     

Reconstitution of cutaneous neural-immunological networks following bone marrow transplantation

Examination was made of the urinary and biliary excretion of the metabolites of genistein and genistein, the major components of Glycine and Sophora genus in rats. The urine of rats administered genistein orally contained eight metabolites. Three of these metabolites, genistein 4'-O-sulfate (M-1), genistein 7-O-beta-D-glucuronide (M-3), genistein 4'-O-sulfate 7-O-beta-D-glucuronide (M-6), were identified from spectroscopic and chemical data. The bile of rats administered genistein orally contained M-2, M-3 and M-6. M-6, a major biliary metabolite, was isolated and identified from spectroscopic and chemical data. The urine or bile of rats treated with genistein, the glycoside of genistein, contained M-1-M-8 or M-2, M-3, M-6 in the above metabolites. These findings suggest that genistein is absorbed as genistein after hydrolysis in the gastrointestinal tract. The total cumulative amounts of the two metabolites and genistein excreted in the urine during 48h, or of M-6 excreted in the bile during 36h following the oral administration of genistein, were approximately 5.7% or 16.0% of the doses administered, respectively. The result show that M-1, M-3 and M-6, having a free hydroxyl, glucuronide- or sulfate-conjugated hydroxyls at the C-7 or C-4' position, are excreted in the urine and bile as parts of the metabolites of genistein.     

Skin manifestations of graft-versus-host reaction following bone marrow transplantation

We review the cutaneous manifestations of acute and chronic graft versus host disease (GvHD). Acute GvHD is characterized by initial itching, pain on pressure and erythema which begins on posterior auricular skin, palms and soles. The disease evolves into a typical but nonspecific maculopapular rash. Confluent rashes and follicular erythema may occur. Erosive oral lesions usually develop. The most severe variant of GvHD is toxic epidermal necrolysis, which often has a fatal outcome. The onset of chronic GvHD usually occurs more than 100 days after bone marrow transplantation and may be preceded by the acute form. The spectrum of skin changes includes lichenoid pruritic lesions with violaceous color and scleroderma-like skin involvement. Investigation of unknown rashes in these patients includes skin biopsy, which clearly differentiates leukocytoclastic vasculitis and erythema exsudativum multiforme with lymphocytic vasculitis from cutaneous manifestations of GvHD. Special stains may reveal bacteria and fungus in septicemic patients. The therapeutic options are discussed.     

Energy level and sleep quality following bone marrow transplantation

Hypothalamic-pituitary-adrenal (HPA) axis disturbances in depressed children with a history of abuse were examined. Thirteen depressed abused, 13 depressed nonabused, and 13 normal control children were given 1.0 microgram/kg of human corticotropin-releasing hormone (CRH) intravenously. Blood samples for corticotropin (ACTH) and cortisol were obtained at nine intervals. When compared to depressed nonabused and normal control children, depressed abused children had significantly greater peak, total, and net ACTH secretion post-CRH. Increased ACTH secretion was only observed in depressed abused children experiencing ongoing chronic adversity (marital violence, emotional abuse, poverty, lack of supports). The pattern of findings of the depressed abused children experiencing ongoing adversity parallels the pattern of HPA axis dysregulation reported in animal studies of chronic stress. They add to a growing body of literature suggesting measures of past trauma and current adversity are important sources of variability in psychobiological correlates of major depression.     

Quality of life following third molar removal: a patient versus professional perspective

We report a case of pleomorphic adenoma with extensive squamous metaplasia in the palate of a 52-year-old Chinese man. The dimensions of the tumor were 15 x 13 x 13 mm. More than 95% of the epithelial element in the tumor was composed of sheets of squamous cells with cyst formation. The pathogenesis, potential diagnostic pitfalls, proliferative activity and cytokeratin expression of this tumor are discussed.     

Fatal interstitial pulmonary disease in a patient with dyskeratosis congenita after allogeneic bone marrow transplantation

Local control rate by radical radiation therapy was analyzed in 33 patients with a piriform sinus cancer. Twenty-five patients (76%) were in stage T3 + T4. Local recurrence-free survival at 3 years was 49% in T1 + T2 and 25% in T3 + T4 (p = 0.01). In T1 + T2 lesions, a biologically effective dose for an acute reaction over 80 Gy and total treatment time less than 70 days appeared to improve local control. In T3 + T4 lesions, good radiation response assessed by the regaining of laryngeal mobility affected local control favorably. An esophageal involvement and destruction of the laryngeal cartilage as well as soft tissue extension precluded the possibility of local control by radiation therapy alone. In addition to the T-stage, other tumor factors should also be considered for predicting local control with radiation therapy.     

Long-term persistence of hemopoietic chimerism following sex-mismatched bone marrow transplantation

Wegener's granulomatosis is a distinct clinicopathologic entity characterized by granulomatous vasculitis of the upper and lower respiratory tract and glomerulonephritis. This disease can present as a clinical picture which resembles sepsis and adult respiratory distress syndrome (ARDS). Wegener's disease requires immunosuppression which can have detrimental consequences when used in sepsis. The following case report illustrates the diagnostic difficulties encountered by intensive care physicians treating severe pulmonary failure and multiple organ dysfunction in Wegener's granulomatosis appearing as ARDS with sepsis. CASE REPORT: A 19-year-old female patient had developed acute respiratory and renal failure after a prolonged period (many months) of antibiotic resistant otitis, sinusitis and mastoiditis. The patient had required intubation at another hospital and there was a history of tension pneumothorax and cardiopulmonary resuscitation during mechanical ventilation. Emergency extracorporeal membrane oxygenation (ECMO) for acute hypercapnic and hypoxic respiratory failure was instituted and the patient was transported to our institution while on ECMO. The patient was treated empirically for suspected pulmonary and systemic infection and received hydrocortisone (0.18 mg/kg/h) as part of a protocol-driven treatment of septic shock in addition to antibiotic and antimycotic regime. The use of ECMO was required for 10 and mechanical ventilation for another 50 days after admission. After successful extubation, central nervous system dysfunction became evident with a somnolent and generally unresponsive patient. When the hydrocortisone dose was gradually tapered, the clinical status of the patient further deteriorated, pulmonary gas exchange worsened and she developed renal failure with proteinura and hematuria. A renal biopsy was performed demonstrating vasculitis and focal segmental glomerulonephritis, a systemic granulomatous vasculitis was suspected; the serum was tested for anti-proteinase 3 antibodies (PR3-ANCA) and turned out to be positive (17.5 U/ml; normal range < 7 U/ml). The morphologic findings from renal biopsy, the positive test for antiproteinase 3 antibodies and the pulmonary-renal involvement with evidence of multisystem disease established the diagnosis of Wegener's granulomatosis. Immunosuppressive therapy with cyclophosphamide and prednisolone was instituted resulting in rapid improvement with recovery of pulmonary, renal and central nervous system function within two weeks. The use of ECMO in this patient served as a life-saving immediate measure usefull to "buy time" until a definite diagnosis could be established. ARDS represents an uniform pulmonary reaction to a large number of different noxious stimuli and disease entities. This case demonstrates that intensive care physicians caring for critically ill patients with ARDS should include even rare causes of pulmonary injury into their differential diagnosis.     

Outcomes following mechanical ventilation in children undergoing bone marrow transplantation

Between 1976 and 1992, 869 patients <19 years of age underwent BMT at the University of Minnesota for a variety of malignant and non-malignant disorders. One hundred and ninety-six required mechanical ventilation (MV) at some time from the start of pre-BMT cyto reduction through the first year following BMT. Reasons for MV included respiratory compromise, upper airway management and non-pulmonary indications for respiratory support. In multivariate models, underlying diagnosis, receipt of HLA-mismatched marrow and the presence of acute graft-versus-host disease (aGVHD) were independent predictors of the need for MV. Indication for MV, underlying diagnosis, and presence of aGVHD were independent predictors of successful extubation. Overall survival at 2 years was 14% among MV patients and 52% among non-MV patients. While the need for MV during BMT reduces the overall likelihood of survival, 40% of children who required MV were successfully extubated; 35% of these extubated patients were long-term survivors. This outcome is better than that reported for adult BMT patients requiring respiratory support, who show survival of <5% at 6 months following BMT. Our data suggest extrapolation of outcome data from adult to pediatric patients is not appropriate and aggressive care of pediatric patients requiring respiratory support is not futile.     

Unrelated bone marrow transplantation in a Wiskott-Aldrich syndrome patient sharing two HLA-extended haplotypes with the donor

OBJECTIVE: To determine the distribution and amount of elastic fibers in the dermis of clinically normal dogs and dogs with dermatoses, particularly solar dermatitis. DESIGN: Skin specimens from 7 anatomic sites were obtained from 19 clinically normal dogs after euthanasia to evaluate the normal distribution of elastic fibers. Biopsy specimens also were obtained from 34 dogs with dermatoses, including 16 with solar dermatitis. Tissue sections were stained with H&E, Verhoeff-van Gieson, and periodic acid-Schiff. ANIMALS: 19 clinically normal dogs and 34 dogs with dermatoses. PROCEDURE: Numbers of elastic fibers were graded subjectively. Comparisons between clinically normal dogs and dogs with dermatoses were made. RESULTS: Normal elastic fibers were present in low numbers in the dermis of adult dogs, regardless of anatomic site or presence or severity of dermatitis. Condensed elastotic material was visualized in only 2 dogs with solar dermatitis. In both dogs, the elastotic material was Verhoeff-van Gieson and periodic acid-Schiff stain positive but was not visible with H&E stain. The most frequent histopathologic finding in the dermis of dogs with solar dermatitis was superficial dermal fibrosis. CONCLUSIONS: The dermis of clinically normal dogs does not contain abundant elastic fibers. Alterations of elastic fibers in dogs with solar dermatitis are rare. Superficial dermal fibrosis may be a better indicator of solar damage.     

Treatment of adrenoleukodystrophy with bone marrow transplantation

Three children with adrenoleukodystrophy (ALD) underwent allogeneic bone marrow transplantation (BMT) between 1992 and 1993. The first boy had attention deficits, marked neuropsychological deficits and widespread demyelination in the frontal lobes on MRI before transplantation. Four years later he has mentally deteriorated and the demyelination on MRI has progressed. The second boy had no symptoms but had white matter lesions on MRI when diagnosed. He was regularly followed with MRI and neuropsychological investigations until BMT 18 months later. A progress of the lesions was noted on the initial MRI investigations, and 4 months before BMT a worsening of deficits in attention and kinaesthetic praxis could be observed. He rapidly deteriorated after the transplantation and died 18 months later. Both PCR and in situ hybridization confirmed the presence of donor cells in the brain. The third boy had no symptoms but white matter lesions on MRI when diagnosed. The neuropsychological tests remained normal but a slight progress was observed on MRI just before transplantation. This boy is still healthy 3.5 years after BMT. BMT as treatment for ALD has to be considered very early, even if a child without symptoms but signs of demyelination on MRI, if a suitable donor is available.
