Response to the combined administration of interferons alpha and gamma after failure of single interferon therapy in chronic myelogenous leukaemia

A previously untreated patient with benign phase chronic myelogenous leukaemia (CML) was treated with recombinant Interferon alpha-2 b. Haematological remission was induced for a total of twelve months. Thereafter, the patient developed resistance to Interferon alpha manifested by an increase in leucocyte counts despite dose escalation (up to 7 x 10(6) IU/day s.c.). Subsequent treatment with recombinant Interferon gamma failed to control myeloid proliferation. However, combined administration of both Interferon alpha and Interferon gamma resulted in a renewed haematological remission which lasted six months.     

Status of allogeneic bone marrow transplantation in childhood in the GDR

Of 25 HLA-identical, MLC negative transplants 10 patients had acute lymphoblastic leukaemia (ALL), 8 acute nonlymphoblastic leukaemia (ANLL), 3 severe aplastic anaemia, 2 malignant histiocytosis, 1 patients neuroblastoma and 1 Fanconi anaemia. 3 HLA nonidentical, MLC positive transplants were performed, two children had malignant infantile osteopetrosis and 1 child had a severe combined immunodeficiency disease. Patients with ALL and ANLL received cyclophosphamide and single dose total body irradiation. 3 patients received fractionated TBI. The results for the allogeneic group overall indicate that the actuarial disease free survival rate is 0.62. 16 of 25 patients are in continuous complete remission (CCR) periods of 3-78 months posttransplant. All three transplanted children with severe aplastic anaemia alive disease-free for periods of 21-81 months. 10 patients with ALL were transplanted (2 in first remission for high risk ALL, 8 in second remission). 7 of 10 patients are alive and disease-free (CCR rate 0.67). 8 patients underwent BMT for ANNL while in first remission in 7 patients and in third partial remission in 1 patient. 4 of 8 patients are alive and disease-free for periods of 25-56 months (CCR rate 0.50). 1 patient with neuroblastoma stage IV survives 24 months, 1 child with Fanconi anemia died on day +25 of GVHD and septicaemia. 1 of the 2 patients transplanted for malignant histiocytosis relapsed 3 months posttransplant, 1 patient is alive and disease-free 5 months posttransplant. In none of the HLA-nonidentical and MLC positive transplantations T-cell depleted marrow engrafted.     

Combination Chemotherapy using L-Asparaginase,Daunorubicin, and Cytosine Arabinoside in Adults with Acute Myelogenous Leukaemia

Cytosine arabinoside and daunorubicin used in an intensive intermittent regimen have been shown to be an effective combination for the induction of complete remissions in 14 out of 23 adult patients with acute myelogenous leukaemia. This gives an overall complete remission rate of 60%. A further patient had a good partial remission. The addition of L-asparaginase to the regimen has not increased the incidence of remission and there were more side effects in the L-asparaginasetreated group. Of the 10 patients treated with L-asparaginase in addition to cytosine arabinoside and daunorubicin, five achieved a complete remission. Of the 13 patients treated with cytosine arabinoside and daunorubicin without L-asparaginase, nine achieved a complete remission and one a good partial remission.     

Dermatomyositis as paraneoplastic syndrome of peritoneal and ovarian relapse after long-term complete remission in patient with metastatic bilateral breast cancer

Dermatomyositis is a rare disease characterised by inflammatory muscle affection and characteristic cutaneous changes. When occuring in a patient with cancer, dermatomyositis may indicate recurrence or progression and poor outcome. Herein, the treatment of metastatic breast cancer, metastatic pattern, characteristics of long-term survivors, and link between dermatomyositis and breast cancer are discussed and the literature reviewed. We report a 57-year old female patient with metastatic bilateral breast cancer whose ovarian and peritoneal relapse after long-term remission was disclosed by occurence of paraneoplastic dermatomyositis. The patient previously had a 15-year long disease free-period after primary treatment for breast cancer before onset of pulmonary dissemination. Following antracycline-based chemotherapy, the complete remission lasting another 15 years was accomplished. Dermatomyositis had been resolved upon induction of second-line taxane-based chemotherapy. After completion of six cycles of gemcitabine and paclitaxel chemotherapy, check-up revealed further progression. The patient subsequently underwent six cycles of third-line CAP chemotherapy (cyclofosfamide, doxorubicine, cisplatin) but disease progressed and oral capecitabine chemotherapy was initiated. The patient received four cycles of capecitabine followed by further vast progression and finally expired following massive pulmonary embolism. Our case stresses the need of thorough staging and check-up when dermatomyositis arises in patients with breast cancer, regardless of previous stable long-term complete remission. Furthermore, we believe that treatment with curative intent in young patients with metastatic breast cancer, who have good performance statuses and no comorbidities is required, because it is more likely to produce long-term complete remission. However, following disease relapse a poor outcome can be expected.     

Validation of ACR/EULAR definition of remission in rheumatoid arthritis from RA practice: the ESPOIR cohort

Introduction

In development of the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) rheumatoid arthritis (RA) remission definitions using clinical trials data, one criterion used to compare different remission definitions was whether, compared with those not in remission, those in remission had evidence of later disease stability defined by x-ray and functional status. Validation of the RA remission criteria using observational study data is necessary before recommending their use in practice.

Methods

Using data from those who met RA criteria in the ESPOIR cohort, we matched each person in remission with a person not in remission and then carried out analyses comparing later stability of x-ray and health assessment questionnaire (HAQ) between the two groups. We compared the predictive validity of the same candidate definitions of remission evaluated in the ACR/EULAR process. To minimize potential bias and produce more stable results, we used a bootstrap resampling approach to select those not in remission, repeating the sample matching analysis process 500 times.

Results

Results were similar to those of clinical trials analyzed for the ACR/EULAR remission criteria. Specifically, the ACR/EULAR remission definitions using either an simple disease activity index (SDAI) ≤ 3.3, clinical disease activity index (CDAI) ≤ 2.8 or a definition of remission requiring tender joint count, swollen joint count, patient global assessment all ≤ 1 performed as well or better than other candidate definitions of remission in terms of predicting later x-ray and function stability.

Conclusions

ACR/EULAR definitions of remission developed for trials are similarly valid in observational studies in RA and could be used in practice.     

Intravenous and oral demethoxydaunorubicin (NSC 256-439) in the treatment of acute leukemia and lymphoma: a pilot study

Demethoxydaunorubicin (DMDR), a new anthracycline available both for intravenous and oral administration, was given in 14 cases of leukaemia, non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM) replacing either daunorubicin (DNR) or doxorubicin (DOX) in conventional chemotherapy regimes. In acute leukaemia (6 myeloblastic and 1 common lymphoblastic) there were 5 complete (CR) and 2 partial (PR) remissions; one patient, previously brought into remission with a regime including i.v. DMDR was thereafter maintained in CR with oral DMDR. Among the patients treated with the oral DMDR, 2 NHL cases were treated; 1 patient had a sustained remission of 12 months so far, with DMDR alone; another patient had a CR with a combined regime. In MM, one patient with very advanced disease treated with i.v. DMDR/CHOP did not respond, but three cases treated with oral DMDR plus other drugs showed a partial remission. Toxic effects were limited to brief episodes of nausea and vomiting in a few i.v. treated patients; a prolonged bone marrow depression was observed in one case only. No cardiotoxic effect was recorded.     

Plasma Insulin during Remission in Juvenile Diabetes Mellitus

Three juvenile diabetics in partial remission were studied before and after the recurrence of overt diabetes. The remissions were partial because glucose tolerance never returned to normal. However, it improved sufficiently to cause the discontinuance of insulin therapy for at least four months.The insulin output in response to double glucose tolerance tests was increased during remission. The degree of remission seemed to be related to the magnitude of the insulin response to glucose. In two of the patients the increase was low and the response very slight. The third patient, however, had a delayed hyper-response and his carbohydrate tolerance during the remission was much more improved than those of the other patients.     

Treatment of acromegaly

Mortality is increased in individuals with acromegaly unless serum growth hormone (GH) levels are below 2 microg/l and serum insulin-like growth factor (IGF)-I levels are normal following treatment. These combined criteria have been used to define remission of the disorder in this review. Transsphenoidal surgery achieves remission targets in an average of 55% of patients. For those not in remission following surgery, options include repeat surgery or use of adjuvant therapy. Fractionated external beam pituitary radiotherapy achieves 10-year remission rates of 47% but leaves patients exposed to excess GH until remission occurs. Stereotactic radiotherapy and gamma knife radiosurgery achieve remission rates of 40% over 3 years, and dopamine agonists produce remission in about 20% of patients. Somatostatin analogues induce remission in 59% of patients within the first year of treatment. The GH receptor antagonist pegvisomant leads to remission in 90% of patients, using IGF-I levels for assessment. Optimal treatment for a patient with acromegaly thus depends on the likely efficacy of treatment, cost, surgical skill, severity of side effects, tolerability, control of tumour growth, and improvement in complications related to tumour mass. A primary surgical approach, followed by medical therapy for those not in remission, remains the preferred option in most centres.     

Leiomyosarcoma of the stomach and small intestine

Three cases of leiomyosarcoma are presented. The primary lesion to the stomach was seen in 2 patients while the small intestine in the remaining patient. Two patients underwent radical surgery. All patients were treated with multiple drug regimens. Radiotherapy was additionally carried out in one patient. One patient who underwent radical surgery and given maintaining chemotherapy is alive in the complete remission since 6 years while two remaining patients died within 3 and 6 years because of recurrence and haematopoietic proliferation.     

An analytical biomarker for treatment of patients with recurrent B-ALL after remission induced by infusion of anti-CD19 chimeric antigen receptor T (CAR-T) cells

Anti-CD19 chimeric antigen receptor-modified T (CAR-T-19) cells have emerged as a powerful targeted immunotherapy for B-cell lineage acute lymphoblastic leukemia with a remarkable clinical response in recent trials. Nonetheless, few data are available on the subsequent clinical monitoring and treatment of the patients, especially those with disease recurrence after CAR-T-19 cell infusion. Here, we analyzed three patients who survived after our phase I clinical trial and who were studied by means of biomarkers reflecting persistence of CAR-T-19 cells in vivo and predictive factors directing further treatment. One patient achieved 9-week sustained complete remission and subsequently received an allogeneic hematopoietic stem cell transplant. Another patient who showed relapse after 20 weeks without detectable leukemia in the cerebrospinal fluid after CAR-T-19 cell treatment was able to achieve a morphological remission under the influence of stand-alone low-dose chemotherapeutic agents. The third patient gradually developed extensive extramedullary involvement in tissues with scarce immune- cell infiltration during a long period of hematopoietic remission after CAR-T-19 cell therapy. Long-term and discontinuous increases in serum cytokines (mainly interleukin 6 and C-reactive protein) were identified in two patients (Nos. 1 and 6) even though only a low copy number of CAR molecules could be detected in their peripheral blood. This finding was suggestive of persistent functional activity of CAR-T-19 cells. Combined analyses of laboratory biomarkers with their clinical manifestations before and after salvage treatment showed that the persistent immunosurveillance mediated by CAR-T-19 cells would inevitably potentiate the leukemia-killing effectiveness of subsequent chemotherapy in patients who showed relapse after CAR-T-19-induced remission.     

Disseminated histoplasmosis with lesions restricted to the larynx in a patient with AIDS. Report of a case and review of the literature

Histoplasmosis is an endemic and systemic mycosis, caused by the dimorphic fungus Histoplasma capsulatum var capsulatum. Disseminated disease in immunocompromised patients generally results from the reactivation of latent foci after a prolonged period of asymptomatic infection. We report a case of laryngeal histoplasmosis as the unique clinical manifestation of a progressive form of the disease in a patient with advanced HIV/AIDS disease. Histopathological analysis of laryngeal biopsy smears revealed granulomas containing Histoplasma-like organisms. Treatment with amphotericin B followed by itraconazole resulted in complete remission of laryngeal lesions. To our knowledge, this is the third case report of laryngeal histoplasmosis in a patient with AIDS.     

Long term remission of metastatic placental site trophoblastic tumor (PSTT): Case report and review of literature

BACKGROUND: Placental site trophoblastic tumor (PSTT) is a rare and unique form of gestational trophoblastic disease (GTD). This tumor represents a neoplastic transformation of intermediate trophoblastic cells. We document a case of long term remission in a patient with metastatic PSTT. CASE PRESENTAION: A 27-year-old patient with metastatic PSTT was treated with combination therapy (chemotherapy and surgery). Patient is alive after 10 years without any evidence of recurrence. Literature on PSTT was searched using Medline and cross references, and pertinent articles were reviewed. CONCLUSION: With surgery and chemotherapy it is possible to achieve long-term remission in metastatic PSTT. Only a handful of previously reported cases with prolonged remission had been treated with the described combined chemotherapy and surgical approach. We suggest that this approach may be recommended for metastatic PSTT.     

Extramedullary Relapse of the AML Transformed from MDS Following Auto-HSCT: A Case Report

The treatment for AML (Acute myeloid/myelogenous leukemia) transformed from MDS (myelodysplastic syndrome) is difficult and controversial clinically, especially in elder patients. In this case report, we diagnosed a 59-year-old female patient with AML-M2a transformed form MDS which might be caused by her chemotherapy for mastocarcinoma. After achieving complete remission (CR) through combined chemotherapy, autologous peripheral blood stem cell transplantation (auto-PBSCT) was attempted. Following auto-HSCT, marrow showed continuous CR but the patient later developed extramedullary bone-infiltration relapse. Then local radiotherapy has been applied, and the patient now has prolonged survival. This is the first (or a successful) case report of auto-HSCT in an elderly patient with AML transformed from MDS.     

Scene segmentation techniques for the analysis of routine bone marrow smears from acute lymphoblastic leukemia patients.

Automated analysis of lymphoblast cell morphology is being evaluated as a basis for predicting the response to therapy of patients with acute lymphoblastic leukemia. A new technique of scene segmentation particularly applicable to the "cluttered" images of cells in routine bone marrow smears is described. Morphologic characteristics of lymphoblasts found in bone marrow smears made at time of diagnosis were measured by an automated, interactive image-processing system using the new scene segmentation technique. These characteristics, on a patient by patient basis, are being compared to remission length and survival data to develop and test new prognostic methods.     

Beneficial effects of high daily dose bromocriptine treatment in Cushing's disease.

Treatment with a high daily dose bromocriptine was evaluated in 6 Cushing's disease patients (4 females and 2 males; aged 23 to 56 years). The highest doses administered were 40 mg to patient 1, 55 mg to patient 2, 35 mg to patient 3, 25 mg to patient 4, 25 mg to patient 5, and 17.5 mg to patient 6. The former 3 cases, 2 (patients 1 and 2) of whom were previously reported and further followed up, showed clinical and biochemical improvement with the regimen. Patient 1 who obtained remission with 40 mg/day has been on remission for further 14 months with a total of 36 months. Patient 2, who had a reduction in pituitary tumor size with 35 mg daily, relapsed thereafter. The therapy, however, resolved the paradoxical responses of plasma ACTH and cortisol to arginine. Readministration of bromocriptine resulted into another clinical and biochemical improvement with 45 to 55 mg/day. Patient 3, a relapsed case after a remission with reserpine plus pituitary irradiation, showed an improvement in the 24-h urinary free cortisol excretion with 35 mg/day. Patient 4 was the only case who had a marked decrease in plasma cortisol (basal; 16.3, nadir; 1.9 micrograms/dl) after a single-dose bromocriptine test among the 5 cases tested. The patient had favorable response with 25 mg/day for 2 months but the dose was not increased after an escape. Patient 5 received the drug in 4 occasions, 7.5 to 25 mg/day, in combination with several agents, which failed to induce clinical remission. The last patient did not respond to a maximum dose of 17.5 mg/day. These observations suggest that, regardless of the result of a single-dose bromocriptine test, treatment with a high daily dose of bromocriptine, 35 mg or more, may be necessary to obtain a favorable clinical response and normal cortisol secretion.     

HRV Biofeedback for Pediatric Irritable Bowel Syndrome and Functional Abdominal Pain: A Clinical Replication Series

Irritable bowel syndrome (IBS) and Functional Abdominal Pain (FAP) are among the most commonly reported Functional Gastrointestinal Disorders. Both have been associated with varying autonomic dysregulation. Heart Rate Variability Biofeedback (HRVB) has recently begun to show efficacy in the treatment of both IBS and FAP. The purpose of this multiple clinical replication series was to analyze the clinical outcomes of utilizing HRVB in a clinical setting. Archival data of twenty-seven consecutive pediatric outpatients diagnosed with IBS or FAP who received HRVB were analyzed. Clinical outcomes were self-report and categorized as full or remission with patient satisfaction, or no improvement. Qualitative reports of patient experiences were also noted. Full remission was achieved by 69.2 % and partial remission was achieved by 30.8 % of IBS patients. Full remission was achieved by 63.6 % and partial remission was achieved by 36.4 % of FAP patients. No patients in either group did not improve to a level of patient satisfaction or >50 %. Patient’s commonly reported feeling validated in their discomfort as a result of psychophysiological education. Results suggest that HRVB is a promising intervention for pediatric outpatients with IBS or FAP. Randomized controlled trials are necessary to accurately determine clinical efficacy of HRVB in the treatment of IBS and FAP.     

Complete remission of liver metastasis of pancreatic cancer under vaccination with a HLA-A2 restricted peptide derived from the universal tumor antigen survivin

Purpose: As prognosis of advanced pancreatic cancer remains gloomy, novel therapeutic modalities have to be developed. Immunotherapy, which targets tumor-associated antigens of tumor cells or tumor stroma, is currently under investigation. As survivin is expressed by neoplastic and tumor endothelial cells, but rarely by normal cells, this antigen appears as an intriguing target molecule. Methods: A 72-year old patient, suffering from pancreatic cancer refractory to gemcitabine therapy, received the survivin-based peptide vaccinations consisting of 100 μg of a modified HLA-A2 restricted survivin_96–104 epitope in Montanide®. Each visit the patient was assessed for adverse events, quality of life and immunological response. Immunemonitoring was performed by IFN-γ-ELISPOT analysis of peripheral blood lymphocytes. Clinical outcome was evaluated by repetitive computed tomography. Results: Under vaccination with survivin peptides the patient initially underwent partial remission of liver metastasis which proceeded after 6 months into a complete remission with a duration of 8 months. Immunological monitoring revealed strong vaccine-induced immune-reactivity against survivin. Unfortunately, after the patient was weaned from vaccination in state of no evidence of disease, he developed recurrent disease. Conclusion: T-cell responses against survivin-expressing cells of the tumor itself and tumor endothelium should impact tumor growth and metastasis. The presented patient with pancreatic cancer is the first example of a successful application of a survivin-based vaccination in the clinical setting. An ongoing phase I/II trial with HLA-A1, -A2 and -B35 restricted survivin peptides for patients with advanced cancer will provide further information towards this notion.     

Pericarditis in the course of acute leukemia

Among 140 patients with acute leukemia (AL) diagnosed according to FAB criteria, pericarditis was diagnosed clinically in 5 of them. They were 2 women and 3 men with different types of AL (L2-in one, M2-in one, M3-in one and M4-in two persons). It occurred in one patient at the onset of the disease and was associated with hyperuricemia, in another one--in complete remission, in the third--during partial remission, and in remaining two patients--during induction therapy. In all patients pericarditis was manifested by fever up to 38-40 degrees C, tachycardia and pericardial friction, in 3-heart silhouettes were enlarged. The ECG revealed mainly depression of ST segments. In 1 case only ECG pattern was typical of pericarditis. Clinically the symptoms of right ventricle failure predominated in 3 and of septic shock--in 2 patients. The etiologic factors were: Pseudomonas aeruginosa 2 X, Enterobacter cloacae 1 X, tuberculosis infection 1 X and hyperuricemia and Enterobacter sepsis 1 X. Pericarditis was favourably influenced by treatment with antibiotics, cardiaca and diuretics in 4 patients. One patient died of a sepsis. In no case the patient's death was attributable to pericarditis. The results of postmortem examinations in 79 cases of AL has revealed three additional cases of pericarditis due to tuberculosis infection, Staphylococcus aureus sepsis and aspergillosis.     

Secondary leukemia after severe aplastic anemia

We describe a patient with acute myeloid leukemia (AML) occurring 5 years after successful treatment of severe aplastic anemia (SAA) with antilymphocyte globulin (ALG). Four years after ALG, SAA had relapsed. A second remission of SAA was achieved, but was followed by transformation of the myelodysplastic syndrome into overt AML. After 2 courses of high-dose cytosine arabinoside and VP-16 complete remission occurred. This case shows that chemotherapy of secondary leukemia after SAA is feasible, and that ex-aplastic bone marrow is capable of complete recovery from chemotherapy-induced aplasia. Morphological anomalies of bone marrow noticed early during remission of SAA might predict a late transformation in leukemia.     

Plasmacytoma of the breast. Unusual initial presentation of myeloma: report of two cases and review of the literature

Two patients who presented initially with breast masses proven to be plasmacytomas, are described. In both cases the breast masses led to the diagnosis of multiple myeloma, which was retrospectively already present at the time of the breast biopsy. One patient with IgG lambda-type myeloma developed plasma cell leukemia and amyloidosis and failed to respond to radiochemotherapy. The second patient was in complete remission, four years after therapy, but has subsequently relapsed and died. All cases of breast plasmacytoma, described in the medical literatures are reviewed, and guidelines for future therapy are suggested.
