[Development and long-term prognosis of unexplained persistent inflammatory biologic syndromes].

PURPOSE: Unexplained inflammatory syndrome is a frequent and worrying condition in Internal Medicine. However, the long-term clinical outcome of these patients cannot be inferred from the literature. The aim of this study is to describe the long-term follow-up and the prognosis of a group of patients hospitalised for an inflammatory syndrome and discharged without causal diagnosis. METHODS: This retrospective study was carried out on 46 patients, 15 men and 31 women, aged 21 to 90 years, hospitalised between 1992 and 1999. Data concerning the hospital stay were obtained from the patients' medical record. Follow-up was performed by consulting the treating physician. RESULTS: The prognosis of these patients is fairly good. In one third of the cases, the inflammatory syndrome resolved spontaneously (n = 13). In the second third, a definite diagnosis was established after discharge (n = 14) and consisted mainly of chronic inflammatory diseases (n = 9), cured with a specific treatment. In the remaining third (n = 12), the inflammatory syndrome persisted, in clinically asymptomatic patients. CONCLUSION: These results suggest that the persistence of an inflammatory syndrome is not a poor prognostic factor. Thus we propose for patients discharged with an undiagnosed persistent inflammatory syndrome despite thorough investigations, a simple clinical and biological follow-up instead of repeated etiological investigations.

Nonchemotherapy drug-induced agranulocytosis: experience of the Strasbourg teaching hospital (1985-2000) and review of the literature.

Agranulocytosis is a life-threatening disorder that frequently occurs as an adverse reaction to drugs. The overall incidence of nonchemotherapy drug-induced agranulocytosis (DIA) ranges from 2.6 to 10 cases per million patients exposed to drugs per year. Although patients experiencing DIA may initially be asymptomatic, the severity of the neutropenia usually leads to severe sepsis, requiring intravenous broad-spectrum antibiotic therapy. In this setting, old age, septicaemia, shock, and the metabolic complications of infection, such as renal failure, are poor prognostic variables. The severity of neutropenia (< 0.1 x 10(9))/l) and its duration (> 10 days) may also impact negatively on the outcome. With appropriate management using pre-established procedures, the mortality rate is now around 5%. Haematopoietic growth factors have been shown to shorten the duration of neutropenia in DIA. However, it has yet to be determined whether their use translates into a better outcome in DIA patients experiencing sepsis. DIA still remains a rare event. However, given the increased life expectancy and subsequent longer exposure to drugs, as well as the development of new agents, physicians should be aware of this complication and its management.

Efficacy of amphotericin B lipid complex in the treatment of invasive fungal infections in immunosuppressed paediatric patients.

The safety and efficacy of amphotericin B lipid complex (ABLC) were evaluated in a retrospective study of 46 paediatric patients with invasive infections. The study included a large proportion of patients who were refractory to or intolerant of conventional antifungal therapy. The mean age of the children was 9.7 +/- 4.8 years. Primary underlying conditions included mainly haematopoietic stem cell transplantation, leukaemia and lung transplantation. The mean daily dose given was 4.11 mg/kg for a mean duration of 38.7 days. At the end of therapy, 38 of 46 (83%) patients responded successfully to treatment with ABLC, including 18 of 23 (78%) with aspergillosis and 17 of 19 (89%) with candidiasis. ABLC was well tolerated, with a low incidence of adverse events. The mean creatinine value was 74.5 microl/mol/l at baseline and 78.2 micromol/l at the end of therapy. These results support the use of ABLC in the treatment of invasive fungal infections in children, including patients who have previously failed, or are intolerant of, traditional antifungal regimens.

Treatment of 21 cases of invasive mucormycosis with amphotericin B colloidal dispersion.

The aim of this study was to review the characteristics and outcome of 21 patients with invasive mucormycosis treated with amphotericin B colloidal dispersion (ABCD) in five phase I and phase II studies. Mucormycosis is an increasing concern in immunocompromised patients, in whom mortality exceeds 60%. The standard treatment has been amphotericin B combined with surgical debridement. Twenty-one patients with invasive mucormycosis treated with ABCD, a lipid complex of amphotericin B and cholesteryl sulfate, were identified. Patients were given ABCD on the basis of pre-existing renal insufficiency, development of nephrotoxicity during amphotericin B therapy, or fungal infection that failed to respond to amphotericin B. Response could be evaluated in 20 patients, all of whom had bone marrow or organ transplantation, haematologic malignancies, or diabetes. Infection was disseminated in six patients and localised to the sinuses, lower respiratory tract, or skin in the other patients. ABCD was given at a mean dose of 4.8 mg/kg per infusion for a mean duration of 37 days. Twelve of 20 patients responded to ABCD therapy. Response rates were similar when patients were treated with ABCD alone (4/7) and ABCD combined with surgery (8/13), with more complete response obtained in the latter group. No difference in response rate was observed in leukaemic patients (3/5) or transplant recipients (6/10) compared to diabetics (3/5). No renal or hepatic toxicity was observed. These results compare favourably with the results of standard treatment and suggest that ABCD combined with surgery may be a useful therapy in patients with mucormycosis.

Oral cobalamin therapy for the treatment of patients with food-cobalamin malabsorption.

BACKGROUND: The standard treatment for cobalamin (vitamin B(12)) deficiency involves regular intramuscular cobalamin injection. It has been suggested that oral cobalamin therapy may be effective for treating patients who have food-cobalamin malabsorption. SUBJECTS AND METHODS: We prospectively studied 10 patients with cobalamin deficiency and well-established food-cobalamin malabsorption who received 3000 microg or 5000 microg of oral crystalline cyanocobalamin once a week for at least 3 months. Complete blood counts and serum cobalamin, homocysteine, and folate levels were determined at baseline and after 3 months of treatment. Patients were reexamined after 6 months. RESULTS: After 3 months of treatment, all patients had increased hemoglobin levels (mean increase, 1.9 g/dL; 95% confidence interval: 0.9 to 3.9 g/dL;P <0.01 compared with baseline) and decreased erythrocyte cell volume (mean decrease, 7.8 fL; 95% confidence interval: 0.9 to 16.5 fL;P<0.001). However, 2 patients had only minor, if any, responses. Serum cobalamin levels were increased in all 8 patients in whom it was measured. CONCLUSION: Our findings suggest that moderate doses of crystalline cyanocobalamin given orally may be an effective treatment for food-cobalamin malabsorption.

[New lipid formulations of amphotericin B. Review of the literature].

INTRODUCTION: Amphotericin B (amB) remains the gold standard for treatment of invasive fungal infections. Lipid formulations of amB have been developed in an attempt to improve both efficacy and tolerability (especially renal toxicity): amB lipid complex (ABLC), liposomal amB (AmBisome), amB colloidal dispersion (ABCD) and amB in lipid emulsion (Intralipid). This review analyzes the data available in the literature. CURRENT KNOWLEDGE AND KEY POINTS: ABLC, AmBisome and ABCD are effective in various fungal infections, including invasive aspergillosis, systemic candidiasis, cryptococcal meningitis, mucormycosis and fusariosis. These formulations are also effective in persistent febrile neutropenia and in leishmaniosis. The three formulations show little renal toxicity and are safer than conventional amB in this respect. Preliminary data are available on amB in Intralipid: infusion-related adverse effects are reduced, but few data are available on efficacy in documented mycoses. FUTURE PROSPECTS AND PROJECTS: Large-scale comparative clinical trials may clarify issues of relative efficacy in various forms of fungal infections.

[Isolated neurologic disorders disclosing Biermer's disease in young subjects].

INTRODUCTION: In young subjects, the discovery of a cobalamine deficiency (Biermer's disease) at the time of neuropsychiatric disorders even of isolated MRI anomalies is a rare event (less than 0.01%). EXEGESIS: We report two observations of cobalamine deficiency, in patients 30 and 37 years old, revealed by acroparesthesia and spontaneous hypersignal in the T2 sequence of MRI and by a peripheral sensitive neuropathy respectively. CONCLUSION: The neuropsychiatric demonstrations of pernicious anemia are polymorphic with, sometimes, isolated spinothalamic attacks. The MRI can contribute to the diagnosis but more often leads to an erroneous diagnosis. Our observations are of special interest because symptoms occurred apart from supplementation of folates and recovered ad integrum with an early treatment by vitamin B12.

Pancreatic metastasis of alveolar soft-part sarcoma: a case report and review of the literature.

Alveolar soft-part sarcoma is a rare tumour. Patients commonly present with distant metastases both at the time of diagnosis and late in the course of disease. We present a case of pancreatic metastasis, occurring more than six years after diagnosis. Treatment consisted in subtotal pancreatoduodenectomy with pylorus resection. Both specific patterns of relapse and treatment opportunities of this uncommon feature are discussed.

Otological manifestations of acute leukaemia: report of two cases and review of literature.

Otological manifestations exceptionally reveal acute leukaemia, whereas leukaemic infiltration of any tissue is frequent at postmortem examination. We present two cases of acute myeloblastic leukaemia revealed by a loss of hearing due to a middle-ear leukaemic infiltration. The characteristics of such a clinical and radiological finding are emphasized. It is suggested that middle and inner ear can be a 'sanctuary' localization, which might sometimes require radiation therapy to achieve durable and complete remission.

Haematopoietic growth factor in antithyroid-drug-induced agranulocytosis.

Drug-induced agranulocytosis (DIA) is often caused by antithyroid drugs. We retrospectively studied the use of granulocyte colony-stimulating factor (G-CSF) therapy in antithyroid-DIA. Data for 20 patients (10 treated with G-CSF) with antithyroid-DIA (neutrophil count <0.5x10(9)/l) were extracted from a cohort study of DIA patients (n=110). G-CSF (300 microg/day subcutaneously) was used where the neutrophil count was <0.1x10(9)/l, or the patient was aged >70 years, or there were severe features of infection or underlying disease. Mean patient age was 62 years (range 34-87); sex ratio (M/F) was 0.05. Carbimazole (n=19) and benzylthiouracile (n=1) were the causative drugs, at mean doses of 30 mg/day (range 20-60) and 100 mg/day (range 50-150), respectively, for a mean of 37 days (range 31-90). Antithyroid drugs were prescribed for Graves' disease (n=8), thyrotoxicosis related to amiodarone intake (n=6) and multinodular goitre (n=6). Clinical features included isolated fever (n=7), pneumonia (n=5), septicaemia or septic shock (n=5) and acute tonsillitis (n=3). Mean neutrophil count was 0.07+/-0.1x10(9)/l. No patient died. Mean durations of haematological recovery, antibiotic therapy and hospitalization were significantly reduced with G-CSF: 6.8+/-4 days vs. 11.6+/-5; 7.5+/-3.8 days vs. 12+/-4.5; and 7.3+/-4.8 days vs. 13+/-6.1, respectively (all p<0.05). G-CSF induced flu-like symptoms in 30% of patients, but reduced overall costs.
