Fracaso en el tratamiento de lupus eritematoso sistémico en paciente joven: reporte de caso / Failure in the treatment of lupus systemic erythematosus in patient young: case report

El Lupus Eritematoso Sistémico (LES) es una enfermedad autoinmune, multisistémica, episódica que puede llegar a ser fatal. Su sintomatología variable y presentaciones atípicas hacen de esta patología un reto diagnóstico.Se reporta el caso de una paciente mujer de 31 años con antecedente de teratoma de ovario, que refiere desde hace 9 meses la sensación de plentud epigástrica y distensión abdominal compatible con ascitis, acompañada de baja ponderal de peso. El diagnóstico riguroso que incluyó pruebas de laboratorio, de imagen y de líquido ascítico, descartó la etiología neoplásica; llegando a concluir que LES era la causa de estas manifestaciones. Debido a la demora en el diagnóstico y pese a que se inició tratamiento esteroideo, la presentación de una respuesta desfavorable al tratamiento y una infección intercurrente influyó en el desenlace fatal, lo que nos hace considerar la presentación de este caso.

SEOM clinical guidelines for myeloid growth factors.

Neutropenia induced by chemotherapy (CT) is an infection risk factor associated to greater morbidity/mortality and dose-limiting toxicity that on many occasions requires a reduction of the dose of cytostatics or a delay in the administration of treatment. This may have a negative effect on the patient's quality of life and even diminish the efficacy of the treatment, especially when the intention is to cure or prolong survival. Management of treatment or prophylaxis of grade 3-4 neutropenia and febrile neutropenia with myeloid growth factors (CSF) varies very much in clinical practice, both in the time of starting treatment and the types of patients it is given to. The need to generalise and facilitate practice based on clinical evidence has led the Spanish Society of Medical Oncology (SEOM) to prepare clinical practice guidelines on the use of myeloid growth factors.

ESHAP versus rituximab-ESHAP in frail patients with refractory diffuse large B-cell lymphoma.

BACKGROUND: Treatment for refractory lymphoma in frail patients (older, poor performance status, or concomitant diseases) has not been defined. PATIENTS AND METHODS: A total of 100 frail patients naive to rituximab therapy were allocated to be treated with ESHAP (etoposide, methylprednisolone, cytosine arabinoside, and platinum; 53 patients) or RESHAP (rituximab plus ESHAP; 47 patients). Granulocyte colony-stimulating factor was used to ameliorate the presence of severe granulocytopenia. RESULTS: Overall response rate (ORR) and complete response (CR) were similar among ESHAP and R-ESHAP (ORR, 33 patients [62%] and 28 patients [60%], respectively; CR, 20 patients [37%] and 18 patients [36%], respectively). Actuarial curves at 5 years showed that progression-free survival (PFS) and overall survival (OS) were similar: 51% and 31% in the ESHAP arm and 50% and 26%, respectively, in R-ESHAP. Toxicity was severe in both groups; grade 4 granulocytopenia was observed in 30% and 32% of ESHAP and R-ESHAP arms, respectively. Viral infections were more frequent in R-ESHAP (52 cases) than in ESHAP (3 cases). CONCLUSION: Frail patients, who generally have not been accepted in controlled clinical trials, can be treated with aggressive chemotherapy because tolerance is well and improvement in outcome is feasible. Although ESHAP retains the clinical efficacy previously reported in nonfrail patients, the addition of rituximab did not improve response rate, PFS, or OS.

Spanish Society of Medical Oncology consensus for the use of haematopoietic colony-stimulating factors in cancer patients.

Neutropenia is a common complication of cancer chemotherapy. Colony-stimulating factors (CSF) may be used to avoid neutropenia-associated complications. The Spanish Society of Medical Oncology (SEOM) recently constituted a working group to review the main issues concerning the use of CSF and carried out a consensus process about the use of CSF in cancer patients, held in Madrid on 26 May 2006. The group concluded the following recommendations: prophylactic use of CSF is recommended when a rate of febrile neutropenia (FN) higher than 20% is expected without the use of CSF or when additional risk factors for neutropenia exist; therapeutic use of CSF is recommended in order to treat FN episodes but not to treat afebrile neutropenic episodes. In addition, the use of CSF is considered effective when used to mobilise stem cells before high-dose chemotherapy and when used for chemotherapy schedule optimisation in dose-dense and in dose-intense regimens.

Colony-stimulating factors for chemotherapy-induced febrile neutropenia: a meta-analysis of randomized controlled trials.

PURPOSE: Current treatment for febrile neutropenia (FN) includes hospitalization for evaluation, empiric broad-spectrum antibiotics, and other supportive care. Clinical trials have reported conflicting results when studying whether the colony-stimulating factors (CSFs) improve outcomes in patients with FN. This Cochrane Collaboration review was undertaken to further evaluate the safety and efficacy of the CSFs in patients with FN. METHODS: An exhaustive literature search was undertaken including major electronic databases (CANCERLIT, EMBASE, LILACS, MEDLINE, SCI, and the Cochrane Controlled Trials Register). All randomized controlled trials that compare CSFs plus antibiotics versus antibiotics alone for the treatment of established FN in adults and children were sought. A meta-analysis of the selected studies was performed. RESULTS: More than 8,000 references were screened, with 13 studies meeting eligibility criteria for inclusion. The overall mortality was not influenced significantly by the use of CSF (odds ratio [OR] = 0.68; 95% CI, 0.43 to 1.08; P = .1). A marginally significant result was obtained for the use of CSF in reducing infection-related mortality (OR = 0.51; 95% CI, 0.26 to 1.00; P = .05). Patients treated with CSFs had a shorter length of hospitalization (hazard ratio [HR] = 0.63; 95% CI, 0.49 to 0.82; P = .0006) and a shorter time to neutrophil recovery (HR = 0.32; 95% CI, 0.23 to 0.46; P < .00001). CONCLUSION: The use of the CSFs in patients with established FN caused by cancer chemotherapy reduces the amount of time spent in hospital and the neutrophil recovery period. The possible influence of the CSFs on infection-related mortality requires further investigation.

Colony stimulating factors for chemotherapy induced febrile neutropenia.

BACKGROUND: Febrile neutropenia is a frequent event for cancer patients undergoing chemotherapy and it is potentially a life threatening situation. The current treatment is supportive care plus antibiotics. Colony stimulating factors (CSF) are cytokines that stimulate and accelerate the production of one or more cellular lines in bone marrow. Some clinical trials addressed the question of whether the addition of CSF to antibiotics (ATB) could improve the outcomes of patients with febrile neutropenia. The results of these trials are conflicting and no definitive conclusion could be reached. OBJECTIVES: To evaluate the safety and effectiveness of adding colony stimulating factors to ATB when treating febrile neutropenia caused by cancer chemotherapy. SEARCH STRATEGY: The search covered the major electronic databases: CANCERLIT, EMBASE, LILACS, MEDLINE, SCI and The Cochrane Controlled Trials Register. Experts were consulted and references from the relevant articles scanned. SELECTION CRITERIA: We looked for all randomized controlled trials (RCTs) that compare CSF plus antibiotics versus antibiotics alone for the treatment of established febrile neutropenia in adults and children. DATA COLLECTION AND ANALYSIS: Two of the reviewers independently selected, critically appraised and extracted data from the studies. A meta-analysis of the select studies was performed, using Review Manager. MAIN RESULTS: More than 8000 references were screened. Thirteen studies were included. The overall mortality was not influenced by the use of CSF [Odds Ratio (OR) = 0.68; 95% Confidence Interval (CI) = 0.43 to 1.08; p=0.1]. A marginally significant result was obtained for the use of CSF in reducing infection related mortality [OR= 0.51; 95% CI = 0.26 to 1.00; p=0.05], but this result was highly influenced by one study. When this study is excluded from our analysis, this possible benefit disappears [OR= 0.85; 95% CI = 0.33 to 2.20; p= 0.7]. The group of patients treated with CSF had a shorter length of hospitalization [Hazard Ratio (HR) = 0.63; 95% CI = 0.49 to 0.82; p=0.0006] and a shorter time to neutrophil recovery [HR= 0.32; 95% CI = 0.23 to 0.46; p < 0.00001]. REVIEWER'S CONCLUSIONS: The use of CSF in patients with febrile neutropenia due to cancer chemotherapy does not affect overall mortality, but reduces the amount of time spent in hospital and the neutrophil recovery period. It was not clear whether CSF has an effect on infection-related mortality.

Adult purpura fulminans associated with staphylococcal infection and administration of colony-stimulating factors.

Purpura fulminans (PF) is a rare syndrome of progressive haemorragic necrosis due to disseminated intravascular coagulation (DIC) and dermal vascular thrombosis leading to purpura and tissue necrosis. PF is more often associated with either a benign infection or a severe sepsis. Rarely, it has been related to drug intake. We report the case of a 24-year-old female patient who suffered from staphylococcal sepsis and pancytopenia, for which she was treated with antibiotics, granulocyte-colony stimulating factor (G-CSF) and granulocyte/macrophage CSF (GM-CSF). Two days after the last GM-CSF dose, she developed widespread necrotic plaques with erythematous borders and purpura in the breast, arms and legs. Coagulation tests indicated DIC and a skin biopsy showed fibrin thrombi in the superficial dermal vessels. The patient totally recovered after removal of the necrotic tissues and application of skin autografts. Although staphylococcal infection was most probably involved in the development of PF, a role of CSF cannot be excluded in this case.

Myelodysplastic syndromes: a review for nurses.

The Myelodysplastic Syndromes (MDS) are a group of hematologic disorders that resemble hematologic malignancies but are often treated much differently. These syndromes result from a clonal disorder of certain stem cells in the bone marrow. Treatment can range from simple supportive care to new and innovative approaches such as immunotherapy. In general, treatment is dictated by the severity of the presenting disease. Oncology nurses, because of their familiarity with the manifestations of cancer, are particularly qualified to intervene for the patient and family experiencing MDS. Nursing interventions, based on a firm understanding of the underlying disease, include patients and family education. In addition, emotional support and symptom management are important nursing roles.

Use of recombinant granulocyte-macrophage colony stimulating factor in the Brazil radiation accident.

8 patients with bone marrow failure after a caesium-137 radiation accident were treated with recombinant human granulocyte-macrophage colony stimulating factor (rHuGM-CSF). The 7 who were evaluable had prompt increases in granulocytes and bone marrow cellularity. 2 patients died of radiation toxicity and haemorrhage and 2 of bacterial sepsis acquired before the start of rHuGM-CSF treatment. 4 patients survive, including 2 who were treated early and never became infected. This therapeutic approach to radiation-induced granulocytopenia may therefore be useful after radiation and nuclear accidents.
