Prophylaxis of recurrent venous thrombosis with long-term enhancement of fibrinolysis.

The effects of 6 months' combined therapy with phenformin and an anabolic steroid were compared in patients with thrombophlebitis migrans (12 patients) and those with superficial thrombophlebitis (15 patients). In both groups of patients an increase in blood fibrinolytic activity, and "capacity" decrease in platelet adhesiveness, plasma fibrinogen, blood lipids, beta lipoproteins as well as serum cholesterol level were found. A statistically significant decrease in frequency of inflammations in patients with thrombophlebitis migrans occurred. In these patients a return of the previously low "fibrinolytic capacity" to normal values was observed. It seems that prolonged activation of fibrinolysis by means of phenformin and an anabolic steriod may be of value in the prophylaxis of venous thrombosis especially thrombophlebitis migrans.     

Prise en charge à l’âge adulte des patients avec un bloc en 21 hydroxylase

A unit taking care of adults with congenital 21 hydroxylase deficiency (CAH) includes patients with classic CAH, comprising the salt-wasting and the simple-virilizing forms as well as patients with non-classic form. Classic CAH is a rare disease with an incidence of 1/10,000 to 1/15,000, patients have usually been followed in pediatric units and transition represents an important step. Non-classic CAH are more frequent with an incidence of 1/1000. The diagnosis is made at puberty or even when patients are adults. In all cases, genetic counselling is needed. The main issues in patients with CAH are sexuality, fertility, bone health and cardiovascular risk. In classic CAH, fertility is decreased both in women and men; risk of osteoporosis is increased as well as cardiovascular risk. The main problem is to replace the missing glucocorticoids without overtreating patients. Undertreatment induces hyperandrogenism in women, and testicular adrenal rests tumors in men. On the opposite, overtreatment increases body mass index, blood pressure, decreases insulin sensitivity, modifies adipose tissue, increases cardiovascular risk and osteoporosis. In non-classic CAH, fertility is subnormal.     

A 15-year follow-up of AJCC stage III malignant melanoma patients treated postsurgically with Newcastle disease virus (NDV) oncolysate and determination of alterations in the CD8 T cell repertoire.

BACKGROUND: The development of effective adjuvant therapies for the treatment of high-risk melanoma patients is critical for the prevention of metastatic disease and improvement of patient survival. Active specific immunotherapy has been tested as an adjuvant treatment in numerous clinical trials with overall limited, but occasionally promising, success rates. Newcastle disease virus (NDV) oncolysate has been utilized as an adjunctive immunotherapeutic agent in the postsurgical management of these patients. A phase II study initiated in 1975 using adjuvant vaccine therapy composed of allogeneic and autologous human melanoma cells infected with live NDV (NDV oncolysate) in patients with AJCC stage III melanoma following therapeutic lymph node dissection has shown >60% survival rate at 10 years with no adverse effects. Continued long-term analysis of trials with promising early results as well as assessment of immunologic responses generated in these patients may result in improved therapeutic decisions for clinical trials in the future. MATERIALS AND METHODS: We analyzed the 15-year survival of patients treated postsurgically with NDV oncolysate in the phase II study described above. In an attempt to understand the immunological effects of this treatment, we have also carried out a comprehensive analysis of the peripheral blood T cell repertoire in these patients. RESULTS: The overall 15-year survival of this group of patients is 55%. Previous studies have suggested that improved outcome in patients undergoing immunotherapy is correlated with increased numbers of CD8(+)CD57(+) cells. In surviving patients, we observed a striking oligoclonality in the CD8(+) T cell population in peripheral blood, which reflects clonal expansions in the CD8(+)CD57(+) subset. CONCLUSIONS: The data suggest that adjuvant vaccination with NDV oncolysates is associated with prolonged survival of patients with lymph node-positive malignant melanoma and that CD8(+) T cells may be an important component of therapeutic efficacy.     

Detection of polymorphic epithelial mucins in the serum of systemic breast cancer patients using the monoclonal antibody,NCRC-11

Summary Serum from patients with systemic breast cancer was found to contain elevated levels of polymorphic epithelial mucin (PEM) as detected using an immunoradiometric assay employing the monoclonal antibody NCRC-11. PEM was partially purified from pooled sera from these patients and the complex, polymorphic, high-molecular-mass (>400 kDa) mucin was identified by sodium dodecylsulphate/polyacrylamide gel electrophoresis, Western blotting and immunostaining with the NCRC-11 antibody. Serial serum samples from 16 patients with metastatic breast cancer were assayed for circulating PEM defined by the monoclonal antibody NCRC-11. The clinical course of disease in these patients was assessed independently as progressive, static or responsive. Increasing NCRC-11 antigen levels correlated with disease progression in 6/7 patients, and decreasing antigen levels correlated with an objective response to treatment in 5/6 patients. Measurement of NCRC-11-defined PEM antigen in patients undergoing therapy for metastatic breast cancer showed an overall accuracy of 75%.     

Cell electrophoretic and absorption spectrographic investigations of the indirect effect of ultraviolet light on erythrocytes of patients with myocardial infarct and other illnesses]

In 34 patients with myocardial infarct, 14 patients with arterial circulatory bleeding disturbances and 12 dialysis patients, blood was diluted immediately after collection by using an Eagle medium (MEM) which had been irradiated by ultraviolet rays. The erythrocytes of patients with myocardial infarct and circulatory bleeding disturbances responded with a mean increase of negative net surface loading by roughly 6% related to the controls in not-irradiated medium. In the erythrocytes of dialysis patients we found no changes of this kind. After ultraviolet irradiation the uv/vis absorption spectra of the Eagle medium showed an increase of extinction depending on the dosage in the short-wave range and a decrease in the long-wave range. Apparently, these uv-induced changes in the Eagle medium secondarily cause an increase of the surface loading of erythrocytes. In patients with arterial circulatory bleeding disturbances this effect which affects the electrostatic relations particularly in the area of terminal flows could contribute to improving the stability of suspension in the blood, thus having a therapeutic importance for these patients as far as their microcirculation is concerned.     

Evaluation of Hemoptysis in Patients With a Normal Chest Roentgenogram

Hemoptysis is a common presenting complaint in patients with pulmonary disease. Although controversial, many clinicians suggest that all patients with hemoptysis should be evaluated with bronchoscopy to exclude the presence of a serious pathologic condition. We reviewed records for an 18-month period, during which 113 patients had hemoptysis as their principal complaint. In all, 26 of the 113 patients had normal chest roentgenograms. All underwent bronchoscopy as part of their evaluations. Results of bronchoscopy in these patients neither altered therapeutic decisions nor led to diagnoses of specific pathologic processes. We conclude that close observation of patients with normal chest roentgenograms who have hemoptysis may be an acceptable clinical approach.     

Serum leptin levels in community acquired pneumonia (CAP) are related to nutritional status and not to acute phase reaction

To determine whether leptin in patients with CAP acts as a nutritional or as an inflammatory marker and whether leptin plays any role regarding survival, we included 222 patients diagnosed of CAP, 142 men and 80 women, median age 74 years. We did not find significant differences in serum leptin levels between CAP patients and healthy controls, even after adjusting by BMI. Serum leptin levels were directly related with BMI, body fat and muscle mass and inversely related with inflammatory markers, including pro- and anti-inflammatory cytokines. Patients with positive blood cultures showed lower serum leptin and raised inflammatory markers. Although patients who died showed lower values of serum leptin, multivariate analysis showed that the prognostic value of low serum leptin levels depends on impaired nutritional status. In conclusion, we suggest that in CAP patients, leptin does not act as an inflammatory reactant but as a nutritional marker.     

Prevalence of diabetes in glaucoma.

Oral glucose 75 g was given to 352 patients with chronic glaucoma, acute glaucoma, or ocular hypertension and 73 patients without glaucoma. The proportion of patients with shallow anterior chambers who showed an abnormal response was significantly greater than that in patients with deep anterior chambers and in the control group (p less than 0.005). The probability of developing an abnormal response to oral glucose tests increased as the depth of the anterior chamber decreased; these two variables showed a significant negative linear correlation (r = -0.79, p less than 0.001). The high prevalence of autonomic dysfunction in patients with shallow anterior chambers and glaucoma may explain this association. Because of this, acute glaucoma should be regarded as a symptom of diabetes.     

Treatment options in patients with rheumatoid arthritis failing initial TNF inhibitor therapy: a critical review

Conventional disease-modifying antirheumatic drugs such as methotrexate are the mainstay of treatment for rheumatoid arthritis. More recently, biologic agents such as etanercept, infliximab and adalimumab, which act by inhibiting tumour necrosis factor (TNF), have become available. TNF inhibitors have proved to be very effective in patients not responding to conventional disease-modifying antirheumatic drugs. However, about 20% to 40% of patients treated with a TNF inhibitor fail to achieve a 20% improvement in American College of Rheumatology criteria, and more lose response over time (secondary failure or acquired therapeutic resistance) or experience adverse events following treatment with a TNF inhibitor. In this group of patients, therapeutic options were limited until recently and an established treatment approach was to switch from one TNF inhibitor to another. In recent years, therapeutic options in these patients have increased with the introduction of biologic agents with novel mechanisms of action, such as rituximab and abatacept. This review outlines the current evidence in support of the available treatment strategies in patients with an inadequate response or intolerance to an initial TNF inhibitor.     

Intermittent treatment of duodenal ulcer with cimetidine.

Intermittent treatment with short courses of cimetidine given only when symptoms recurred was assessed in patients with duodenal ulcer as an alternative to maintenance treatment. Their progress was followed up for up to 22 months. Gastroscopy was carried out in most attacks to confirm recurrence of the ulcer and subsequent healing. Out of 125 patients treated, 83 relapsed, of whom 21 defaulted. After retreatment 36 patients relapsed again. The pattern of relapse and remission for the group as a whole was similar after both courses of treatment, indicating an unchanged natural history. Nevertheless, wide variation occurred in individual patients, so that the pattern of relapse could not be predicted by the duration of the initial remission. Most patients had one or two or rarely three symptomatic relapses a year, which were rapidly treated successfully with cimetidine. Therefore, unless the necessity for long-term maintenance treatment is established, intermittent treatment provides an adequate alternative in most patients with duodenal ulcer.     

Prognostic value of serial serum interleukin-6 level estimation in patients with lung cancer: a preliminary report.

In the present report, we serially measured the levels of interleukin-6 (IL-6) and some acute-phase proteins (APP) in 61 lung cancer patients undergoing radiotherapy in order to investigate the relationship between the response to the treatment and the changes in parameters of systemic inflammatory response. The patients were divided into two groups depending on the response to the treatment. The first group (referred to as responders) comprised 32 patients with stable disease, partial remission or total remission. Twenty-nine patients with progression of the disease were included to the second group (referred to as non-responders). Six patients died due to the lung cancer during the study. We showed a decrease in IL-6 serum level and C-reactive protein (CRP) level in responders but not in non-responders. However, the most interesting results were obtained after retrospective analysis of the data of six deceased patients. In these patients we observed an elevation of IL-6 and CRP before the patients'' deaths. Following the changes in acute-phase response and interleukin-6 serum levels in lung cancer patients seems to be helpful in prognosis of the outcome of the disease. Based on our data, we conclude that an elevation in IL-6 and/or CRP level in patients with lung cancer may serve as an adverse prognostic factor.     

The treatment of haemophilia A inhibitor with high dose intravenous immunoglobulin

In patients with Haemophilia A, the development of inhibitor is a life-threatening complication of treatment. These patients are at high risk for dangerous bleeding as a result of this acquired resistance to human Factor VIII concentrate. Although treatment of bleeding complications has been improved with the introduction of an activated prothrombin complex preparation, therapy remains unsatisfactory. Two patients with Haemophilia A inhibitor were treated with high dose intravenous immunoglobulin in the expectation of an immunosuppressive effect. A rise in the antibody titre at the same time as the administration of factor VIII concentrate showed that this treatment was ineffective in patients with Haemophilia A inhibitor.     

Impaired elastic-fiber assembly by fibroblasts from patients with either Morquio B disease or infantile GM1-gangliosidosis is linked to deficiency in the 67-kD spliced variant of beta-galactosidase

We have previously shown that intracellular trafficking and extracellular assembly of tropoelastin into elastic fibers is facilitated by the 67-kD elastin-binding protein identical to an enzymatically inactive, alternatively spliced variant of beta-galactosidase (S-Gal). In the present study, we investigated elastic-fiber assembly in cultures of dermal fibroblasts from patients with either Morquio B disease or GM1-gangliosidosis who bore different mutations of the beta-galactosidase gene. We found that fibroblasts taken from patients with an adult form of GM1-gangliosidosis and from patients with an infantile form, carrying a missense mutations in the beta-galactosidase gene-mutations that caused deficiency in lysosomal beta-galactosidase but not in S-Gal-assembled normal elastic fibers. In contrast, fibroblasts from two cases of infantile GM1-gangliosidosis that bear nonsense mutations of the beta-galactosidase gene, as well as fibroblasts from four patients with Morquio B who had mutations causing deficiency in both forms of beta-galactosidase, did not assemble elastic fibers. We also demonstrated that S-Gal-deficient fibroblasts from patients with either GM1-gangliosidosis or Morquio B can acquire the S-Gal protein, produced by coculturing of Chinese hamster ovary cells permanently transected with S-Gal cDNA, resulting in improved deposition of elastic fibers. The present study provides a novel and natural model validating functional roles of S-Gal in elastogenesis and elucidates an association between impaired elastogenesis and the development of connective-tissue disorders in patients with Morquio B disease and in patients with an infantile form of GM1-gangliosidosis.     

Serum antibodies reacting with Escherichia coli heat-labile enterotoxin in sera of patients suffering from Campylobacter jejuni infection

Abstract Using an enzyme-linked immunosorbent assay (ELISA) with purified Escherichia coli heat-labile enterotoxin (LT), an increase in serum antibody against LT was demonstrated in 49% of patients infected with Campylobacter jejuni tested. The antibody titers, however, were not as high as those in patients with cholera. This finding suggests that some strains of C. jejuni in patients with diseases due to C. jejuni produce a toxin (or substance) immunologically related to LT in the intestine.     

In vitro radiosensitivity of human diploid fibroblasts derived from women with unusually sensitive clinical responses to definitive radiation therapy for breast cancer

Between January 1985 and December 1986, 811 patients were treated for carcinoma of the breast at the Joint Center for Radiation Therapy by an identical protocol. Of these 811 patients, five patients (0.6%) were identified as having an unusually sensitive clinical response to routine external beam irradiation. This unusual clinical response was characterized by severe skin erythema and edema during the first few weeks of treatment, requiring treatment breaks. Skin fibroblast cell strains were established from these five women as well as from six women with a normal clinical response to breast irradiation (chosen at random from the population of 811 patients). Radiation survival parameters were determined by a colony formation assay from complete survival curves in coded and blinded samples. Cells from the sensitive patients were significantly more sensitive to the cytotoxic effects of radiation in vitro as determined by the parameters D0, D, D10, and n, than were the strains derived from patients with a normal response. We conclude that an unusually severe response to standard fractionated radiotherapy may be associated with greater intrinsic radiation sensitivity of the individual's somatic cells.     

Prostaglandin E1 infusion therapy in dry age-related macular degeneration

OBJECTIVE: The pilot study is intended to show whether prostaglandin E1 (PGE1) infusions are able to stop the gradual vision loss in dry age-related macular degeneration (AMD) and, further, to stabilize or improve visual acuity. METHODS: With PGE1 infusions 11 patients with different forms of dry AMD were treated and compared with a control group of 10 untreated patients with dry AMD. The target parameter was the visual acuity, as determined with the ETDRS logMAR charts. Other examinations performed during the study were tests of contrast vision, colour vision and central visual fields, as well as autofluorescence and fluorescein angiography and multifocal electroretinography. RESULTS: On termination of the infusions, six patients showed an increase in visual acuity by at least one line, an improvement that was seen in eight patients 2 months after the end of the infusion therapy. After 6 months, one patient exhibited an improvement of visual acuity by three lines and three patients an improvement by one line. Five patients were found to show no change of their baseline acuity values after 6 months, while two patients exhibited an impairment by one line. The visual acuity in the dry AMD control group without PGE1 treatment had decreased by 0.8 lines on the average after 6 months. Contrast vision, central visual fields and the multifocal electroretinogram showed improvements on the termination of infusions and up to 2 months later; no substantial change of these parameters, as compared with the baseline findings, was seen 6 months after the termination of infusions. SUMMARY: This pilot study suggests that PGE1 infusions have a stabilizing or improving effect on the visual acuity of patients with dry AMD. Owing to the limitations of a pilot study, these results should, however, be validated in a larger, randomized and blinded study.     

The assessment of severe head injury by short-latency somatosensory and brain-stem auditory evoked potentials

The relative prognostic value of short-latency somatosensory evoked potentials (SEPs) and brain-stem auditory evoked potentials (BAEPs) was assessed in 35 patients with post-traumatic coma. Analysis of the evoked potentials was restricted to those recorded within the first 4 days following head injury. Abnormal SEPs were defined as an increase in central somatosensory conduction time or an absence of the initial cortical potential following stimulation of either median nerve. Abnormal BAEPs were classified as an increase in the wave I–V interval or the loss of any or all of its 3 most stable components (waves I, III and V) following stimulation of either ear. SEPs reliably both good and bad outcomes. All 17 patients in whom SEPs were graded as normal had a favourable outcome and 15 of 18 patients in whom SEPs were abnormal had an unfavourable outcome. Although abnormal BAEPs were associated with an unfavourable outcome in almost all patients (6 of 7), only 19 of 28 patients with normal BAEPs had a favourable outcome. The finding of normal BAEPs was therefore of little prognostic significance. These results confirm the superiority and greater sensitivity of the SEP in detecting abnormalities of brain function shortly after severe head trauma.     

RAPID HEALING OF PEPTIC ULCERS IN PATIENTS RECEIVING FRESH CABBAGE JUICE

Thirteen patients with peptic ulcer were treated with fresh cabbage juice, which, experiments have indicated, contains an antipeptic ulcer factor. This factor (vitamin U) prevents the development of histamin-induced peptic ulcers in guinea pigs.The average crater healing time for seven of these patients who had duodenal ulcer was only 10.4 days, while the average time as reported in the literature, in 62 patients treated by standard therapy, was 37 days.The average crater healing time for six patients with gastric ulcer treated with cabbage juice was only 7.3 days, compared with 42 days, as reported in the literature, for six patients treated by standard therapy.The rapid healing of peptic ulcers observed radiologically and gastroscopically in 13 patients treated with fresh cabbage juice indicates that the anti-peptic ulcer dietary factor may play an important role in the genesis of peptic ulcer in man.     

Mycophenolate sodium treatment in patients with primary Sjögren syndrome: a pilot trial

The aim of this study was to evaluate the efficacy and safety of mycophenolate sodium (MPS) in patients with primary Sjögren syndrome (pSS) refractory to other immunosuppressive agents. Eleven patients with pSS were treated with MPS up to 1,440 mg daily for an observation period of 6 months in this single-center, open-label pilot trial. At baseline, after 3 months, and after 6 months, we examined the clinical status, including glandular function tests, as well as different laboratory parameters associated with pSS. In addition, subjective parameters were determined on the basis of different questionnaires. Treatment with MPS was well tolerated in 8 of 11 patients. Due to vertigo or gastrointestinal discomfort, two patients did not complete the trial. One patient developed pneumonia 2 weeks after treatment and was withdrawn. In the remaining patients, MPS treatment resulted in subjective improvement of ocular dryness on a visual analogue scale and a reduced demand for artificial tear supplementations. However, no significant alterations of objective parameters for dryness of eyes and mouth were observed, although a substantial improvement of glandular functions occurred in two patients with short disease duration. In addition, treatment with MPS resulted in significant reduction of hypergammaglobulinemia and rheumatoid factors as well as an increase of complement levels and white blood cells. MPS promises to be an additional therapeutic option for patients with pSS, at least in those with shorter disease duration. Further investigations about the efficacy and safety of MPS in pSS have to be performed in larger numbers of patients.
