MVPP chemotherapy regimen for advanced Hodgkin's disease

During January 1968 to December 1972, 133 patients with advanced Hodgkin''s disease (HD) were admitted to hospital for combination chemotherapy with mustine, vinblastine, procarbazine, and prednisolone (MVPP regimen). Remission rates were 76% among 49 untreated patients and 90% among 42 patients who had relapsed after radiotherapy. The corresponding five-year survival rates were 65% and 86% respectively. Provided the observed yearly mortality (6%) remains unchanged 75% of patients who had previously received no treatment or irradiation and achieved remission are expected to continue in first remission after five years. Forty-two patients had received prior chemotherapy. They had lower remission and five-year survival rates (40% and 33% respectively), and fewer than half of those achieving remission were still in first remission after five years. There were several reasons for the poor prognosis in this group, including advanced-stage disease (stage IVB), age over 40, and achievement of remission.Chemotherapy was administered on an outpatient basis. Haematological toxicity and immediate drug-related side effects were similar to those of other regimens but there was no appreciable neurotoxicity. Most deaths were due to either HD itself or complications of advanced disease. Five malignancies other than HD occurred in patients who had received both single-agent chemotherapy and radiotherapy before MVPP chemotherapy. Two patients developed osteonecrosis of the femoral heads.Combination chemotherapy has a profound effect on the prognosis of advanced HD. The MVPP regimen yields results comparable to those of other regimens but with perhaps less toxicity.     

A preliminary report on the use of transfer factor for treating stage D3 hormone-unresponsive metastatic prostate cancer

As conventional treatments are unsuccessful, the survival rate of stage D3 prostate cancer patients is poor. Reports have suggested the existence of humoral and cell-mediated immunity (CMI) against prostate cancer tumour-associated antigens (TAA). These observations prompted us to treat stage D3 prostate cancer patients with an in vitro produced transfer factor (TF) able to transfer, in vitro and in vivo, CMI against bladder and prostate TAA. Fifty patients entered this study and received one intramuscular injection of 2–5 units of specific TF monthly. Follow-up, ranging from 1 to 9 years, showed that complete remission was achieved in 2 patients, partial remission in 6, and no progression of metastatic disease in 14. The median survival was 126 weeks, higher than the survival rates reported in the literature for patients of the same stage.     

Human peripheral lymphocyte transformation induced by the Robina lectin.

The effect of transfer factor was studied in 32 children recuperating from protein-calorie malnutrition. Half of the children were given transfer factor; the other half were given saline in a randomized, double-blind trial. Although unexpectedly low mortality in both groups precluded the adequate evaluation of transfer factor in preventing death during the nutritional recovery period, there was no difference between treated and control patients on a variety of indices of rehabilitation. In addition, transfer factor had no demonstrable effect on the evolution of delayed cutaneous hypersensitivity as both groups of patients recovered from the anergy associated with protein-calorie malnutrition.     

Experimental and clinical studies of drug regulation of the anti-lysozyme activity of microorganisms causing opportunistic infections

Experimental materials on choosing antibiotics for etiotropic therapy of opportunistic infections with an account of the regulating effect of the drugs on the ++anti-lysozyme activity of pathogens (the factor of intracellular parasitism) are presented. The in vitro data were applied to the clinical trials in 30 patients with chronic and acute pyelonephritis of the Proteus etiology and to 25 patients with chronic inflammatory diseases of Staphylococcus etiology. It was shown that the use of the antibiotics which lowered the ++anti-lysozyme activity of microorganisms promoted a more rapid disappearance of the disease clinical signs, increased 2- to 3-fold the terms of the remission and resulted in an increase in the number of the persons with complete remission (54.5 to 63.6 per cent) as compared to the use of the drugs which stimulated the pathogen property or were indifferent to it.     

Transfer factor with anti-EBV activity as an adjuvant therapy for nasopharyngeal carcinoma: A pilot study

Overall survival of nasopharyngeal carcinoma (NPC) at UICC stage IV still remains unsatisfactory even with combination chemotherapy (CT) and radio-therapy (RT). In view of the association of reactivation of Epstein-Barr virus (EBV) with the development and recurrence of NPC, immunotherapy in the form of transfer factor (TF) with specific activity against EBV (TF-B1) was suggested as an adjuvant to a combination of CT and RT in order to improve survival. In the present study, 6 UICC Stage IV patients received TF-B1 and another 6 patients matched for disease stage were given TF prepared from peripheral blood leucocytes (TF-PBL). Results were compared with another 18 patients matched by age, sex, and stage of disease who received standard therapy without TF during the same period (C group). After a median follow up of 47.5 months, the survival for the TF-B1 group was found to be significantly better (P=<0.05) than the PBL and C group. While the 8 patients with distant metastasis (DM), not treated with TF-B1 (6 in the control and 2 in the PBL group), died due to progressive disease (average survival being 14.3 months), both patients with DM in the TF-B1 group had complete remission: one died of tuberculosis after surviving for 3.5 years and another is still alive, disease free, after 4.2 years. Although the series involved a small number of cases, the apparent effect of adjuvant immunotherapy in the form of TF with anti-EBV activity is of considerable interest.     

Complete molecular remissions induced by patient-specific vaccination plus granulocyte-monocyte colony-stimulating factor against lymphoma.

Lymphomas express a tumor-specific antigen which can be targeted by cancer vaccination. We evaluated the ability of a new idiotype protein vaccine formulation to eradicate residual t(14;18)+ lymphoma cells in 20 patients in a homogeneous, chemotherapy-induced first clinical complete remission. All 11 patients with detectable translocations in their primary tumors had cells from the malignant clone detectable in their blood by PCR both at diagnosis and after chemotherapy, despite being in complete remission. However, 8 of 11 patients converted to lacking cells in their blood from the malignant clone detectable by PCR after vaccination and sustained their molecular remissions. Tumor-specific cytotoxic CD8+ and CD4+ T cells were uniformly found (19 of 20 patients), whereas antibodies were detected, but apparently were not required for molecular remission. Vaccination was thus associated with clearance of residual tumor cells from blood and long-term disease-free survival. The demonstration of molecular remissions, analysis of cytotoxic T lymphocytes against autologous tumor targets, and addition of granulocyte-monocyte colony-stimulating factor to the vaccine formulation provide principles relevant to the design of future clinical trials of other cancer vaccines administered in a minimal residual disease setting.     

Inflammatory Bowel Disease Among College Students

Of 52 student patients with chronic inflammatory bowel disease who were observed at Stanford University over a three-year period, 16 had Crohn disease, 17 had ulcerative colitis and 19 had ulcerative proctitis. Patients with ulcerative colitis had relatively few complications. During the study period, only two students from the entire group of 52 were obliged to interrupt college attendance because of bowel disease or complications. Of the patients, 33 were first observed on remission or attained remission during the three-year observation period. Incidence and prevalence rates for Crohn disease and ulcerative colitis were comparable with age-specific rates from other published studies. At Stanford, the high reported frequency of proctitis, which exceeded that of proximal ulcerative colitis, was possibly a reflection of the diagnostic zeal with which patients with rectal bleeding were evaluated at the student health service.

Pulmonary Function after Lymphography

The effects of lymphography on ventilatory function and gas transfer factor were studied in nine patients. Serial measurements made up to one month showed no change in the forced expiratory volume in one second or vital capacity. A small but reversible fall in transfer factor was found. The greatest reduction was at 24 or 48 hours. It was concluded that patients with normal lungs are unlikely to encounter difficulties but that patients with severe lung disease require careful assessment before lymphography.     

Persistent Tn polyagglutination syndrome during febrile neutropenia: a case report and review of the literature

Introduction

Crohn's disease is a chronic inflammatory bowel disease of unknown etiology which may affect any part of the bowel. Fistulas are a common and often serious complication of Crohn's disease. The treatment for fistulizing Crohn's disease can be medical, surgical or a combination of the two. Recently, adalimumab, a fully human anti-tumor necrosis factor monoclonal antibody, has been suggested as a safe and effective treatment for the induction and maintenance of remission in adult patients with moderate to severe Crohn's disease, who are refractory to conventional therapy or intolerant to infliximab. However, large studies focusing on evaluating the efficacy of adalimumab in fistulizing Crohn's disease have not yet been published.

Case presentation

We report the cases of three patients, of European Caucasian ethnicity and Greek nationality, with active luminal and fistulizing Crohn's disease. All of the cases were treated successfully with adalimumab. Patient 1 (a 44-year-old man) and patient 2 (an 18-year-old woman) developed early post-surgical enterocutaneous fistulas, while patient 3 (a 20-year-old woman) had peri-anal fistulizing Crohn's disease. Adalimumab treatment (160 mg subcutaneously at week zero, 80 mg at week two, and 40 mg every other week) was used for three different indications: (1) after the failure of other conservative medical treatments for Crohn's disease (patient 1); (2) as a monotherapy in treating a naive patient (patient 2); (3) after an intolerance to infliximab (patient 3). A remission of the active luminal and fistulizing disease was achieved soon after the initiation of adalimumab and sustained thereafter with maintenance doses. No further surgical intervention was required and no adverse effects were observed in any of the cases.

Conclusions

Fistulizing Crohn's disease remains a challenge in clinical practice. Adalimumab seems to be an effective, well-tolerated and safe treatment option for the induction and maintenance of remission in patients with moderate to severe peri-anal fistulizing Crohn's disease. Furthermore, adalimumab seems to be a promising treatment option for patients with moderate to severe fistulizing Crohn's disease with enterocutaneous fistulas. However, this clinical observation needs to be investigated in further clinical trials.     

Bacille Calmette-Guérin as maintenance therapy for non-Hodgkin's lymphoma.

Following complete remission of non-Hodgkin''s lymphoma by chemotherapy, irradiation or both, 44 patients were studied to assess the value of bacille Calmette-Guérin (BCG) as maintenance therapy. Patients with stage LI, EI or EII disease were allocated at random to receive BCG or no further maintenance therapy, and those with stage LII, LIII, EIII or IV disease received BCG therapy or orally administered cyclophosphamide. BCG had no effect on the duration of remission or the overall survival from the time of randomization. However, after the first recurrence there was a significant improvement in survival in the patients who had received BCG maintenance therapy.     

Hepatitis d virus isolates with low replication and epithelial-mesenchymal transition-inducing activity are associated with disease remission

Clearance of hepatitis D virus (HDV) viremia leads to disease remission. Large hepatitis delta antigen (L-HDAg) has been reported to activate transforming growth factor β, which may induce epithelial-mesenchymal transition (EMT) and fibrogenesis. This study analyzed serum HDV RNA "quasispecies" in HDV-infected patients at two stages of infection: before and after alanine aminotransferase (ALT) elevations. Included in the study were four patients who went into remission after ALT elevation and three patients who did not go into remission and progressed to cirrhosis or hepatocellular carcinoma. Full-length HDV cDNA clones were obtained from the most abundant HDV RNA species at the pre- and post-ALT elevation stages. Using an in vitro model consisting of Huh-7 cells transfected with cloned HDV cDNAs, the pre- or post-ALT elevation dominant HDV RNA species were characterized for (i) their replication capacity by measuring HDV RNA and HDAg levels in transfected cells and (ii) their capacity to induce EMT by measuring the levels of the mesenchymal-cell-specific protein vimentin, the EMT regulators twist and snail, and the epithelial-cell-specific protein E-cadherin. Results show that in patients in remission, the post-ALT elevation dominant HDV RNA species had a lower replication capacity in vitro and lower EMT activity than their pre-ALT elevation counterparts. This was not true of patients who did not go into remission. The expression of L-HDAg, but not small HDAg, increased the expression of the EMT-related proteins. It is concluded that in chronically infected patients, HDV quasispecies with a low replication capacity and low EMT activity are associated with disease remission.     

Recurrences after completion of the treatment of acute lymphoblastic leukemia in children]

Within the past 16 years, 2004 children with the acute lymphoblastic leukemia were treated at the Centres of the Polish Pediatric Study Group. The treatment was completed in 887 patients (44.3%) with the first remission. Recurrence was noted in 180 children (20.3%). This group was analysed in view of the type of therapy and its effect on the survival rate, significance of recurrence following therapy, character and localization of recurrent disease, and further fate of patients. It was found, that patients with isolated late nuclear recurrence have greatest chances to achieve subsequent remission. Most frequent and severe is recurrent bone marrow involvement which requires intensive chemotherapy combined with bone marrow transplantation due to unfavourable prognosis. Patients with the first recurrence of the acute lymphoblastic leukemia have a chance to achieve subsequent remission and long-term survival.     

TFX immunotherapy in children with ALL during remission

The in vivo effect of thymus factor X (TFX) on the E-rosetting capacity, the absolute peripheral blood lymphocytes and T-cell number per microliter, the skin test reactivity to recall antigens, and the immunoglobulin production was evaluated in 20 children with acute lymphoblastic leukaemia. The in vitro effect of TFX was also tested. The mean percentage of E-rosettes in these patients increased from 50 to 64%. Although absolute peripheral blood lymphocyte and T-cell number per microliter rose significantly, the mean values did not reach those in healthy children. The tests with recall antigens were positive in 13% of patients prior to immunotherapy and 32% following the therapy. The influence of immunotherapy on infectious episodes and on the stabilisation of remission was also evaluated. TFX in vivo appears to restore immunocompetence, decrease infections, and prolong remissions in children with ALL in remission.     

Aspects of early arthritis. Definition of disease states in early arthritis: remission versus minimal disease activity

With regard to rheumatoid arthritis, remission as currently used in the literature can have two meanings: either a state with persistent absence of clinical and radiological signs of disease activity without being treated for a specific time period, or it may point to a disease state with minimal disease activity during antirheumatic treatment. A risk factor for the first is absence of autoantibodies, with the anti-CCP-antibodies as best predictors, whereas risk factors for achieving a drug-induced state of minimal disease activity are not well defined. These definitions of remission refer to different disease states; therefore, we propose that the term remission is reserved for patients that are not treated with antirheumatic drugs.     

Levels of autoantibodies against human TSH receptor predict relapse of hyperthyroidism in Graves' disease.

The aim of this study was to evaluate the ability of the more sensitive second-generation TSH receptor (TRAb) assay to predict recurrent Graves' disease (GD) vs. remission depending on TRAb levels. 93 patients with active GD were included in the study. By using a cut-off limit of 1.0 IU/l, all 93 patients were positive for TRAb (median: 4.6 IU/l) at the time of their first visit (single point measurement in median 5.1 months after initial diagnosis). Subsequently, 33 patients went into remission and were euthyroid during follow-up (median follow-up: 21.7 months), whereas 60 patients did not go into remission or developed relapse over the following 24 months. Median TRAb levels in the group of remission were significantly (p < 0.0001) lower than TRAb values in the relapse group (2.1 compared to 8.6 IU/l). Applying ROC plot analysis to compare different TRAb thresholds, a cut-off of 10 IU/l was established. Here, the specificity for relapse was 97 % as only 1 of 29 patients with TRAb values above 10 IU/l went into remission during follow-up, whereas all other 28 patients developed a relapse (positive predictive value for relapse: 96.4 %). In contrast, TRAb values lower than 10 IU/l had no impact on the prediction of remission. In conclusion, our data clearly indicate that TRAb measurement is useful for identifying patients that will not benefit from long-term antithyroid drug treatment.     

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.     

Comparing three‐year extension of early intervention service to regular care following two years of early intervention service in first‐episode psychosis: a randomized single blind clinical trial

This study aimed to determine if, following two years of early intervention service for first‐episode psychosis, three‐year extension of that service was superior to three years of regular care. We conducted a randomized single blind clinical trial using an urn randomization balanced for gender and substance abuse. Participants were recruited from early intervention service clinics in Montreal. Patients (N=220), 18‐35 years old, were randomized to an extension of early intervention service (EEIS; N=110) or to regular care (N=110). EEIS included case management, family intervention, cognitive behaviour therapy and crisis intervention, while regular care involved transfer to primary (community health and social services and family physicians) or secondary care (psychiatric outpatient clinics). Cumulative length of positive and negative symptom remission was the primary outcome measure. EEIS patients had a significantly longer mean length of remission of positive symptoms (92.5 vs. 63.6 weeks, t=4.47, p<0.001), negative symptoms (73.4 vs. 59.6 weeks, t=2.84, p=0.005) and both positive and negative symptoms (66.5 vs. 56.7 weeks, t=2.25, p=0.03) compared to regular care patients. EEIS patients stayed in treatment longer than regular care patients (mean 131.7 vs. 105.3 weeks, t=3.98, p<0.001 through contact with physicians; 134.8 ± 37.7 vs. 89.8 ± 55.2, t=6.45, p<0.0001 through contact with other health care providers) and received more units of treatment (mean 74.9 vs. 39.9, t=4.21, p<0.001 from physicians, and 57.3 vs. 28.2, t=4.08, p<0.001 from other health care professionals). Length of treatment had an independent effect on the length of remission of positive symptoms (t=2.62, p=0.009), while number of units of treatment by any health care provider had an effect on length of remission of negative symptoms (t=?2.70, p=0.008) as well as total symptoms (t=?2.40, p=0.02). Post‐hoc analysis showed that patients randomized to primary care, based on their better clinical profile at randomization, maintained their better outcome, especially as to remission of negative symptoms, at the end of the study. These data suggest that extending early intervention service for three additional years has a positive impact on length of remission of positive and negative symptoms compared to regular care. This may have policy implications for extending early intervention services beyond the current two years.     

Immunotherapy of osteogenic sarcoma with transfer factor

Summary Fifteen patients with osteogenic sarcoma were treated with transfer factor derived from leukocytes of their household contacts. Eight of the fifteen patients were tumor-bearing, and transfer factor therapy was correlated with increased cell-mediated immunity in peripheral blood lymphocytes and with lymphocytic infiltrates into the tumors. There was no marked increased in survival time as compared with historical controls, but this therapy did not accelerate the disease, and there were no untoward side effects.Seven of the fifteen patients were disease-free when transfer therapy was initiated shortly after surgical removal of the primary tumor (five patients) or solitary pulmonary metastases (two patients). These patients received transfer factor injections every 2 weeks for 1–2 years. Six of the seven patients are disease-free 62–82 months after surgery. Compared with probabilities of 5-year survival computed from historical controls, this is significant at P<0.008. Abbreviations used in this paper are: CI, cytotoxicity index; GCT, giant cell tumor of bone; HHC, household contacts; HHC_os, household contacts of patients with osteogenic sarcoma; MIC, mononuclear inflammatory cell; TFCI, transfer factor cytotoxicity index; TSTF, tumor-specific transfer factor.     

The gonadotropin releasing hormone stimulation and the clomiphene tests in female patients with anorexia nervosa.

In 9 female patients suffering from acute anorexia nervosa (a.n.) and in two patients in whom this disease had reached the remission phase, the response of the gonadotropin-producing cells in the adenohypophysis was checked by administration of Gn-RH and the degree to which the hypothalamic-hypophyseal axis could be stimulated was checked by administration of clomiphene (5 x 100 mg). Hormonal screening examinations (cervical score after Insler and hormonal vaginal cytology) were used to assay the basal estrogen production. LH and FSH concentrations in the serum were determined radioimmunologically using the principles of the double antibody technique. The gonadotropin-producing cells did not respond to Gn-RH administration in 8 of the 9 patients with acute a.n. The response was disturbed in one of these patients. The response to Gn-RH stimulation was normal in the two patients in the remission phase. Clomiphene had no stimulatory effect on the hypothalamic-hypophyseal axis during either the acute or remission phase. Hormonal treatment during the acute phase of a.n. is not indicated since, after recovery of a normal body weight, the symptoms recede and the cycle normalises spontaneously.
