A Comparison of Nitrogen Mustard and Vinblastine Sulfate in the Treatment of Patients with Hodgkin's Disease

In a crossover study the effectiveness of intermittent maintenance doses of nitrogen mustard was compared to that of vinblastine sulfate in the treatment of 61 patients with advanced Hodgkin''s disease. Forty-five of the patients had had previous radiation therapy. Nine of 29 patients who received nitrogen mustard as the first drug had a complete response and five had a partial response. The comparative results in 32 patients receiving vinblastine sulfate first were nine complete responses and 13 partial responses. The median duration of the complete responses to each drug was 43 weeks. The partial responses were of shorter duration. When the second drug was given in adequate doses, almost as many patients responded with a similar median duration of response.It is concluded that nitrogen mustard and vinblastine sulfate are equally effective single agents in the treatment of patients with advanced Hodgkin''s disease and that patient preference would favour vinblastine sulfate because of its negligible side effects.     

Combination Chemotherapy in Generalized Hodgkin's Disease

Fifty-two patients with generalized Hodgkin''s disease were treated with a combination of mustine hydrochloride, vinblastine, procarbazine, and prednisolone. Complete remissions were obtained initially in six out of seven patients (86%) who had previously received no treatment, in 15 out of 19 (79%) who had had only radiotherapy in the past, and in 9 out of 26 (35%) who had previously been given chemotherapy with or without radiotherapy. Of these 30 patients in whom a complete remission was obtained 22 have been free of any symptoms or signs of disease for periods ranging from 4 to 22 months. The response to treatment was rapid, and toxicity was not a major problem, except in those who had previously been treated with cytotoxic drugs used continuously and not in courses. A comparative trial of radiotherapy and combination therapy in the treatment of Stage III Hodgkin''s disease is strongly recommended.     

Optimal therapy for adults with langerhans cell histiocytosis bone lesions

Background

There is little data on treatment of Langerhans cell histiocytosis (LCH) in adults. Available data is on small numbers of patients with short follow-up times and no comparison of results from different treatment regimens. We analyzed the responses of adult LCH patients with bone lesions to three primary chemotherapy treatments to define the optimal one.

Methods and Findings

Fifty-eight adult patients with bone lesions, either as a solitary site or as a component of multisystem disease, were analyzed for disease location and response to surgery, curettage, steroids, radiation, vinblastine/prednisone, 2-Chlorodeoxyadenosine (2-CdA), or cytosine arabinoside (ARA-C). The mean age of patients was 32 years, with equal gender distribution. Twenty-nine patients had 1 lesion; 16, 2 lesions; 5, 3 lesions; and 8 had 4 or more. Most bone lesions were in the skull, spine, or jaw. Chemotherapy, surgery, curettage, or radiation, but not steroids alone, achieved improvement or resolution of lesions in a majority of patients. Comparison of the three chemotherapy regimens revealed 84% of patients treated with vinblastine/prednisone either did not respond or relapsed within a year, whereas 59% of patients treated with 2-CdA and 21% treated with ARA-C failed. Toxicity was worse with the vinblastine/prednisone group as 75% had grade 3–4 neuropathy. Grade 3–4 cytopenias occurred in 37% of the 2-CdA -treated patients and 20% of the ARA-C-treated patients. The major limitation of this study is it is retrospective and not a clinical trial.

Conclusions

ARA-C is an effective and minimally toxic treatment for LCH bone lesions in adults. In contrast, vinblastine/prednisone results in poor overall responses and excessive toxicity.     

Combined interferon and vinblastine treatment of advanced melanoma: evaluation of the treatment results and the effects of the treatment on immunological functions

Summary Thirteen patients with metastatic malignant melanoma received interferon -2a (Roferon-A) and vinblastine. The interferon dosage was increased from 3×10⁶ IU to 9×10⁶ IU daily in 10 weeks and thereafter 9×10⁶ IU was administered three times weekly intrasmuscularly. Vinblastine (0.075–0.15 mg/kg) was given every third week intravenously. One of the ten evaluable patients had partial remission (PR) (11%) for 10 months. The diseases was stabilized (NC) in three patients (30%) for 3, 6 and 9 months. Progression (PD) occurred in six patients. The treatment time varied from 5 weeks to 44 weeks. The median survial time from the beginning of this combination treatment was 5 months. The most common side-effects were fever, fatigue, loss of taste, weight loss and neutropenia.The mitogen response to phytohemagglutinin and purified protein derivative of tuberculin decreased in all patients. The response to concanavalin A decreased less and began to increase again in the patients with PR and NC. The natural killer cell activity in PD patients decreased more than in the patients with PR and NC. The ratio of T4/T8-positive cells was restored in PR + NC patients but rose in PD patients indicating a difference in the immunomodulatory effect of the combination or of the advanced disease itself on T-cell function in PD patients.This combination of daily interferon and vinblastine did not prove to be effective in melanoma. The depression of immunological functions, which was more marked in patients with PD, might indicate that vinblastine in this combination counteracts the immunostimulatory effect of interferon.     

Infectious syphilis in Canada in 1986.

Thirteen men with a median age of 37 (range 28 to 46) years who had extensive Kaposi''s sarcoma associated with acquired immune deficiency syndrome (AIDS) were treated with combination chemotherapy and alpha-interferon. Four patients had stage III disease and nine had stage IV disease (one with pulmonary and eight with gastrointestinal involvement). Treatment consisted of monthly courses of actinomycin D, 1 mg/m2, and vinblastine sulfate, 6 mg/m2, given intravenously on day 1, bleomycin, 10 mg/m2 given intravenously on days 1 and 8, and human lymphoblastoid (alpha-) interferon, 10 million U/m2 given subcutaneously three times a week for six doses starting on day 14. Forty-one treatment cycles (median 3, range 1 to 12) were administered. The median granulocyte and platelet counts on day 14 before the start of interferon therapy were 600 X 10(9)/L and 134 X 10(9)/L respectively; the counts did not fall further during interferon therapy. There was no difference in T-cell subsets, 2'',5''-oligoadenylate synthetase level or results of blastogenesis studies after interferon therapy. Four patients required admission to hospital for neutropenia-associated fever. A complete response (of 24 weeks'' duration) was seen in one patient and a partial response (of 14 to 44 weeks'' duration) in four. One patient had a mixed response, with regression of skin involvement but progression of pulmonary disease. The median length of survival was 48 (range 4 to 143) weeks. Eleven patients died of progressive Kaposi''s sarcoma, one of lymphoma and one of Pneumocystis carinii pneumonia. The results suggest that this form of therapy is not appropriate for patients with Kaposi''s sarcoma associated with AIDS.     

Randomised trial of two-drug and four-drug maintenance chemotherapy in advanced or recurrent Hodgkin's disease. Medical Research Council's working party on lymphomas.

Between 1970 and 1975, 108 patients who presented with advanced or recurrent Hodgkin''s disease and were free of disease after six courses of chemotherapy with mustine, vinblastine, procarbazine, and prednisone (MVPP) were allocated at random to one of two regiments of maintenance treatment: either intermittent treatment with vinblastine and procarbazine or intermittent treatment with MVPP. After a median follow-up period of nearly five years there was no significant difference between the two groups in either the rate of relapse or death rate. Six of the 55 patients given the two-drug regimen died compared with 10 of the 53 given the four-drug regimen. The four-drug required hospital attendance and was less agreeable than the two-drug regimen. The efficacy of maintenance chemotherapy with the two-drug regimen was no less than that with the four-drug regimen, but the two-drug regimen had several practical advantages.     

Clinical analysis of the treatment of spinal cord injury with umbilical cord mesenchymal stem cells

Background aimsThe purpose of this study was to observe the clinical effect and safety of umbilical cord mesenchymal stem cells (UC-MSCs) in treating spinal cord injury (SCI) by intrathecal injection.MethodsFrom January 2008 to October 2010, we treated 22 patients with SCI with UC-MSCs by intrathecal injection; dosage was 1 × 10⁶ cells/kg body weight once a week given four times as a course. Four patients received two courses, one patient received three courses and all other patients received one course. American Spinal Injury Association scoring system and International Association of Neurorestoratology Spinal Cord Injury Functional Rating Scale were used to evaluate neural function and ability to perform activities of daily living.ResultsTreatment was effective in 13 of 22 patients; nine patients had no response. Among patients with incomplete SCI, the response to treatment was 81.25%; there was no response to treatment among six patients with complete SCI. Five patients with a response to treatment received two to three courses of therapy, and effects in these patients were further enhanced. In most patients in whom treatment was effective, motor or sensory functions, or both, were improved, and bowel and bladder control ability was improved. In 22 patients 1 month after therapy, algesia, tactile sensation, motion and activity of daily living scale were significantly improved (P < 0.01). During therapy, common adverse effects were headache (one case) and low back pain (one cases); these disappeared within 1–3 days. No treatment-related adverse events occurred during a follow-up period ranging from 3 months to 3 years.ConclusionsUC-MSC therapy by intrathecal injection is safe and can improve neurologic function and quality of life in most patients with incomplete SCI.     

Early antibiotic treatment of reactive arthritis associated with enteric infections: clinical and serological study.

OBJECTIVE--To find out whether a 10-14 days'' course of antibiotics early in the course of reactive arthritis associated with enteric infections could reduce the severity and duration of the disease and whether the antibody response in patients with reactive arthritis associated with yersinia infection differed between those treated and those not treated with the antibiotics. DESIGN--Prospective multicentre trial in which patients were randomised to treatment or no treatment with antibiotics. Patients were seen at three and six weeks and three, six, nine, 12, and 18 months after their first visit. SETTING--Departments of infectious diseases in three hospitals in Linköping, Malmö, and Stockholm, Sweden. PATIENTS--40 Consecutive patients who had had symptoms of reactive arthritis associated with enteric infection for less than four weeks. INTERVENTIONS--20 Patients were allocated to treatment with antibiotics and 20 patients did not receive antibiotics. All patients received non-steroidal anti-inflammatory drugs, and four also received intra-articular steroid injections after at least six weeks'' observation. MAIN OUTCOME MEASURES--Arthritic symptoms assessed clinically and by using Ritchies'' index; blood measurements reflecting inflammatory activity; serum IgG, IgM, and IgA antibody titres; HLA tissue type. RESULTS--No difference was observed concerning duration of arthritis, grade of inflammation, and number of joints affected between patients treated and those not treated with antibiotics. Furthermore, there was no significant difference between the two groups in erythrocyte sedimentation rate and haptoglobin, IgG, and IgA concentrations. All values had returned to normal within three months. No patient developed chronic arthritis, but sustained slight arthralgia occurred in three patients. The HLA-B27 antigen was found in 23 (58%) of the patients, and its presence did not affect clinical outcome. The IgG, IgM, and IgA antibody responses were similar in patients treated with antibiotics and those not treated. CONCLUSION--Short term antibiotic treatment has no beneficial effect on the clinical outcome of reactive arthritis associated with enteric infection.     

Metyrapone in long-term management of Cushing's disease.

Metyrapone was used in the long-term management of 13 patients with pituitary-dependent bilateral adrenal hyperplasia (Cushing''s disease). The total length of treatment ranged from two to 66 months, with a mean of 21 months. The clinical features of the disease rapidly improved on metyrapone and this improvement was maintained. Although plasma ACTH concentrations rose in all patients, the increase was insufficient to overcome the adrenal blockade induced by the drug. Eight of the 13 patients had additional external pituitary irradiation as definitive treatment of their disease and one underwent a transfrontal hypophysectomy. Radiotherapy cured one patient, and after three years metyrapone was withdrawn. Slight hirsuties was noted in four of the seven women who received the drug for six months or more. A fifth woman had more severe hirsuties and this led to bilateral adrenalectomy. Other than hirsuties, side effects were few and the routine use of metyrapone is recommended as an adjunct to more definitive treatment in all patients who present with Cushing''s syndrome, irrespective of aetiology.     

Comparison of high-dose intravenous methylprednisolone with low-dose oral prednisolone in acute renal allograft rejection in children.

Two corticosteroid regimens were compared in a randomised, prospective study of 48 consecutive acute rejection episodes occurring at least one month after transplantation in 22 children who had received renal allografts. The higher dose schedule (intravenous methylprednisolone 600 mg/m2 daily for three days) was no more effective than the lower (oral prednisolone 3 mg/kg daily for three days) in reversing rejection, being successful in 70% as opposed to 72% of episodes. Few major side effects were seen with either treatment, but unpleasant sensations were reported much more frequently in the group given intravenous methylprednisolone; this regimen was much more disruptive of the patient''s life. Oral prednisolone in the dosage described is as effective as about 10 times that dose of intravenous methylprednisolone; it is much cheaper and is viewed as less unpleasant by patients.     

Controlled trial of trimipramine,monoamine oxidase inhibitors,and combined treatment in depressed outpatients.

A study was carried out in which 135 mildly or moderately depressed outpatients were randomly allocated to one of five groups receiving six weeks'' treatment weith antidepressant drugs. The groups received a tricyclic antidepressant (trimipramine; mean dose 106 mg at night) or a monoamine oxidase inhibitor (MAOI) (phenelzine or isocarboxazid; mean doses 45 and 32 mg/day respectively), or a combination of the two (phenelzine plus trimipramine or isocarboxazid plus trimipramine). Various scales were used to measure depression before and at one, three, and six weeks of treatment, and results were assessed blindly. The tricyclic antidepressant was found to be consistently superior to the MAOIs and the combined treatments. Some differential indicators of response to the various antidepressants were found--for example, patients with initial complaints of dizziness, suicidal ideas, irritability, and insomnia and a longer duration of illness were more likely to respond to trimipramine--but these were of only modest significance. Side effects were not troublesome in any group. It is concluded that neither MAOIs nor MAOIs combined with tricyclic antidepressants are the treatment of first choice in unselected outpatients with mild or moderate depression.     

Albendazole chemotherapy for treatment of diarrhoea in patients with AIDS in Zambia: a randomised double blind controlled trial.

OBJECTIVE--To determine the value of short course, high dose albendazole chemotherapy in the treatment of persistent diarrhoea related to HIV in unselected patients in urban Zambia. DESIGN--A randomised double blind placebo controlled trial of albendazole 800 mg twice daily for two weeks. Patients were monitored intensively for one month and followed for up to six months. SETTING--Home care. AIDS services in Lusaka and Ndola. PATIENTS--174 HIV seropositive patients with persistent diarrhoea (defined as loose but not bloody stools three or more times a day for three weeks or longer). No investigations were undertaken except HIV testing after counselling. MAIN OUTCOME MEASURES--Proportion of time periods during which diarrhoea was experienced after completion of treatment; proportion of patients with full remission after completion of treatment; mortality. RESULTS--The patients taking albendazole had diarrhoea on 29% fewer days than those taking placebo (P < 0.0001) in the two weeks after treatment. The benefit of albendazole was maintained over six months. In patients with a Karnofsky score of 50 to 70 (needing help with activities of daily living and unable to work, but not needing admission to hospital) diarrhoea was reduced by 50%. Remission was obtained in 26% of all patients who received albendazole (P = 0.004 against 9% receiving placebo), and this difference was maintained over six months (log rank test, P = 0.003). Albendazole had no effect on mortality. Minimal adverse effects were noted. CONCLUSIONS--For HIV infected Zambians with diarrhoea of more than three weeks'' duration albendazole offers substantial relief from symptoms and may be used empirically, without prior investigation.     

Study on the Effects of Tablet Colour in the Treatment of Anxiety States

Forty-eight patients with anxiety states were treated with oxazepam (Serenid-D), which was administered in tablets of three different colours—red, yellow, and green. Every patient received one week''s treatment with each colour, according to a random programme. A latin square design was used to ensure complete balance between the colours and between the weeks. The patients'' symptoms were categorized and then assessed by both weekly physicians'' ratings and daily self-rating, which showed close agreement. Colour preference was shown on both these scales in that symptoms of anxiety were most improved with green, whereas depressive symptoms appeared to respond best to yellow. Such colour preferences, however, did not reach levels of statistical significance, except for phobias as rated on the physicians'' assessment.The results indicate that colour may play a part in the response to a drug.     

Comparison of chloroquine,pyrimethamine and sulfadoxine,and chlorproguanil and dapsone as treatment for falciparum malaria in pregnant and non-pregnant women,Kakamega District,Kenya.

OBJECTIVE--To compare treatment and protection against falciparum malaria in pregnant and non-pregnant women with three drug regimens. DESIGN--Prospective intervention study with six weeks'' follow up. Patients received one of three drug regimens in order of entry. SETTING--Primary care hospital and secondary girls'' school in rural western Kenya. PATIENTS--158 of 988 pregnant women (89 primigravid and 69 multigravid) in the third trimester and 105 of 1488 non-pregnant schoolgirls of reproductive age were parasitaemic (more than 500 asexual forms/microliter. These women were divided into three treatment groups by gravid state. INTERVENTIONS--Women were treated with chloroquine base 25 mg/kg over three days or pyrimethamine 75 mg and sulfadoxine 1500 mg as a single dose or chlorproguanil 1.2 mg/kg and dapsone 2.4 mg/kg as a single dose. MAIN OUTCOME MEASURES--Parasitaemia and haemoglobin concentrations measured at seven day intervals for six weeks. RESULTS--Primigravid women were more likely to be parasitaemic on follow up than multigravidas or nulligravidas, whose response was about the same. Parasites did not clear by day 7 in primigravidas in six (20%) of 30 who received chloroquine, three (8%) of 35 treated with pyrimethamine and sulfadoxine, and none of 23 treated with chlorproguanil and dapsone. At day 28, 83%, 19%, and 67% of primigravidas in these treatment groups were parasitaemic. Haemoglobin concentrations rose in all women, but improvement was sustained only in women who remained free of parasites. CONCLUSIONS--Clearance of parasites was better with either pyrimethamine and sulfadoxine or chlorproguanil and dapsone than with chloroquine. Longest protection was obtained with pyrimethamine and sulfadoxine.     

Immunotherapy of lung cancer with Corynebacterium parvum

Summary Thirty-one patients with inoperable carcinoma of the lung, excluding oat-cell carcinoma, were randomized to receive either chemotherapy alone, with methyl CCNU and vinblastine every 6–8 weeks (15 Pts) or such chemotherapy plus immunotherapy with IV infusions of Corynebacterium parvum (16 Pts). Prior duration of the disease was longer, and more patients had received previous therapy, in the immunotherapy group; these groups were otherwise very similar. In vitro lymphocyte response to phytohemagglutinin did not change significantly in either group, but the weaker response to Varidase declined in both groups after chemotherapy. An increased baseline level of circulating B lymphocytes was sharply reduced in the C. parvum group. There were no differences in -globulins or delayed skin test responses between immunotherapy and control patients at entry into this study or on follow-up. Median survival from entry was longer in the immunotherapy group (6 months) than in the control group (3 months), but this difference was not statistically significant and only two patients in each group lived for more than 11 months. It is conceivable that more benefit from C. parvum might have been recorded had more effective chemotherapy been available.     

Slow infusions of vinblastine in the treatment of adult idiopathic thrombocytopenic purpura: a report on 43 cases

Forty-three adult patients with idiopathic thrombocytopenic purpura (ITP) were treated by slow intravenous infusions of vinblastine. Nineteen had ITP of recent onset (i.e. of less than 6 months duration) and had contraindication to steroids (3 patients), refractoriness to steroids (6 patients) or to steroids and high dose intravenous immunoglobulins (IVIg, 10 patients). Of the 19 patients, 10 achieved complete response (CR), 2 achieved partial response (PR), 2 had minor response (MR) and the remaining 5 patients had no response (NR). Six of the complete responders remained in CR after 12 to 48 months, whereas all other responders relapsed within 3 months, in spite of maintenance therapy. Twenty-four patients had chronic ITP (i.e. of 6 months duration or more) and had showed no or only transient response to steroids and/or splenectomy, and in many of them, to other therapeutic approaches. Four achieved CR, 4 PR, 6 MR and 10 NR. All but 3 responses were shorter than 3 months, in spite of maintenance therapy. Most responses to slow infusions of vinblastine began after the first infusion. Main side effects included leukopenia in 9 patients (but with absolute neutropenia in only one) and peripheral neuropathy in 2 patients. Interval from diagnosis was the only prognostic factor of response to treatment. We conclude that slow infusions of vinblastine may be a useful approach in ITP of recent onset, when contraindication or refractoriness to steroids and/or IVIg exists. In our experience, this treatment has limited benefit in chronic ITP. In addition, it remains to be demonstrated that slow infusions of vinca alkaloids have any superiority over intravenous bolus injections of the same drugs.     

Posaconazole Salvage Treatment for Invasive Fungal Infection

Invasive fungal infection (IFI) is an important cause of morbidity and mortality. Posaconazole is a second generation triazole with a broad spectrum, and it may be suitable for salvage antifungal treatment although posaconazole is not usually considered to be as first-line antifungal therapy for IFI. The purpose of this study was to assess the utility of posaconazole salvage treatment for IFI. We conducted a retrospective review of patients with salvage antifungal treatment with posaconazole for IFI at our institution between December 2007 and July 2012. A total of ten patients received posaconazole salvage IFI. Etiology of IFI was consisting of mucormycosis (four patients), Paecilomyces variotii (one patient), and unspecified IFI etiology (five patients). Causes of posaconazole treatment were following; intolerance of previous antifungal therapy in five patients, refractory IFI on previous antifungal therapy in four patients, and both intolerance of previous antifungal therapy and refractory IFI on previous antifungal therapy in one patient. Duration of posaconazole salvage treatment ranged from 15 to 355 days with median 47 days. The overall successful posaconazole salvage treatment response rate was 80.0 % (8 of 10 patients). There were three patients who died during the study period. However, only one death was attributed to the progression of IFI. Two patients discontinued posaconazole due to adverse events. Posaconazole salvage treatment was effective antifungal therapy for IFI. Further studies are needed to define the optimal therapeutic strategy.     

Manipulation in treatment of low back pain: a multicentre study.

In a multicentre trial 456 selected patients with low back pain were randomly allocated to one of four treatments-manipulation, definitive physiotherapy, corset, or analgesic tablets. Patients were reassessed clinically after three weeks'' treatment and again after a further three weeks. Questionnaires were used to find out the patients'' condition three months and one year after admission to the trial. There were never any important differences among the four groups of patients. A few patients responded well and quickly to manipulation, but there was no way of identifying such patients in advance. The response to a corset was slow, but the long-tern effects were at least as good as those of the other treatments. Patients treated only with analgesics fared marginally worse than those on the other three treatments. There is no strong reason, however, for recommending manipulation over physiotherapy or corset.     

Intravenous methylprednisolone in the treatment of Graves' ophthalmopathy.

Eleven euthyroid patients with severe Graves'' eye disease were treated with intravenous methylprednisolone and followed up for six months or more by ophthalmological assessment, orbital computed tomography (CT), photographs, and antibody measurements. Papilloedema resolved in the single patient in whom it was present; visual acuity was abnormal in seven eyes initially and in only one eye after treatment; the intraocular pressure differential, which reflects muscle dysfunction, was initially abnormal in 18 eyes but showed a progressive and distinct improvement; nine patients showed substantial improvement in inflammatory signs. Exophthalmos improved early after treatment, but this improvement was not maintained. Orbital CT showed a pronounced reduction in the bulk of eye muscles after treatment in eight of nine patients. Autoantibodies to the thyroid stimulating hormone receptor declined. Adverse effects were trivial. Thus eight patients showed a clear response to intravenous methylprednisolone as judged by ophthalmic assessment and CT scan. The two patients who showed little response and one who had none all had a long history (more than a year) of ophthalmopathy. Results were better than those with oral steroids and adverse effects less. Treatment of Graves'' eye disease is more likely to be effective if given early; patients should be referred promptly to specialist centres, where treatment with intravenous methylprednisolone should be considered.
