Factors associated with hospital admission and adverse outcome for COVID-19: Role of social factors and medical care.

BACKGROUND: Beyond sex, age, and various comorbidities, geographical origin and socioeconomic deprivation are associated with Coronavirus Disease (COVID-19) morbidity and mortality in the general population. We aimed to assess factors associated with severe forms of COVID-19 after a hospital emergency department visit, focusing on socioeconomic factors. METHODS: Patients with laboratory-confirmed COVID-19 attending the emergency department of Béclère Hospital (France) in March-April 2020 were included. Postal addresses were used to obtain two geographical deprivation indices at the neighborhood level. Factors associated with hospitalization and factors associated with adverse outcomes, i.e. mechanical ventilation or death, were studied using logistic and Cox analyses, respectively. RESULTS: Among 399 included patients, 321 were hospitalized. Neither geographical origin nor socioeconomic deprivation was associated with any of the outcomes. Being male, older, overweight or obese, diabetic, or having a neuropsychiatric disorder were independent risk factors for hospitalization. Among 296 patients hospitalized at Béclère Hospital, 91 experienced an adverse outcome. Older age, being overweight or obese, desaturation and extent of chest CT scan lesions>25% at admission (aHR: 2.2 [95% CI: 1.3-3.5]) and higher peak CRP levels and acute kidney failure (aHR: 2.0 [1.2-3.3]) during follow-up were independently associated with adverse outcomes, whereas treatment with hydrocortisone reduced the risk of mechanical ventilation or death by half (aHR: 0.5 [0.3-0.8]). CONCLUSION: No association between geographical origin or socioeconomic deprivation and the occurrence of a severe form of COVID-19 was observed in our population after arrival to the emergency department. Empirical corticosteroid use with hydrocortisone had a strong protective impact.

[Macrophage activation syndrome, hemophagocytic syndrome]. / Syndrome d'activation macrophagique (syndrome d'hémophagocytose).

Macrophage activation syndrome MAS describes the clinical, biological and histological symptoms related to a probably T lymphocytes/NK cell driven stimulation of macrophages with the consequence of a hemophagocytosis involving numerous organs, preferentially bone marrow, explaining the other term of "hemophagocytic syndrome". Clinical symptoms include cytopenia, multiple organ dysfunction, fever unresponsive to antibiotics, fatigue and rash. Infections (bacteria, virus or parasites), lymphoproliferative disorders, cancers, systemic diseases are the most prevalent triggers or etiologies of M.A.S. Evidence of haemaphagocytosis is obtained in the majority of cases with bone marrow specimens. In some cases haemophagocytosis can spare the bone marrow with involvement confined to other tissues such as liver and spleen. Very high levels of ferritine seem to correlate well with the presence of haemophagocytosis and is a possible marker for an early diagnosis. Early treatment initiation is mandatory. Corticosteroids, cytostatic drugs such as etoposide, cyclosporine A, plasmapherese, intravenous immunoglobulins and anti TNFalpha are proposed but no randomized trials were published.

[Long term survival in metastatic colorectal cancer treated with leucovorin and 5-fluoro-uracil chemotherapy]. / Survie à long terme des cancers colorectaux métastatiques sous chimiothérapie par 5-fluoro-uracile.

PURPOSE: Median survival in advanced colorectal cancer patients treated with 5-fluoro-uracil (5FU) and leucovorin (LV) is between 12 and 18 months. The aim of this study was to evaluate long term survival in this disease. METHODS: We report here, retrospectively, the survival of 445 patients who entered in first-line prospective studies with LV-5FU-based regimen chemotherapy, between 1985 and 1995. RESULTS: Median survival was 18 months. The 3, 5 and 10 year survival were respectively 17.9%, 4.5% and 2.4%. Seventy-five patients survived more than 3 years, among them, 10 achieved a complete and 34 a partial response, 12 had curative liver or lung surgery. Fifteen patients lived more than 5 years, 2 achieved a complete and 7 a partial response. Seven had curative surgery. Eleven patients were still alive in 2002, among them 7 in complete remission at 5 years, including 3 who did not have surgery. CONCLUSION: This study shows that some patients with metastatic colorectal cancer can achieve long survival, especially when secondary curative surgery can be performed. However, 1% of the patients can be cured with LV-5FU chemotherapy alone. These results will be probably improve with the use of the new drugs: oxaliplatin and irinotecan.

[The return of the prodigal child or allergy to ficus]. / Le retour de l'enfant prodigue ou l'allergie au ficus.

Ficus benjamina (FB), the weeping fig, belonging to the Moracea family, is now widely used as an indoor ornamental plant in houses and offices. Its latex can be responsible of IgE allergies : rhinoconjunctivitis, asthma, angiooedema, pruritus, anaphylactic shock. In some occupations such as gardeners, caretakers of plants, it can induce a contact urticaria. Most of these patients are atopics. We describe a case of non-occupational, indoor related rhinoconjunctivitis in a non-atopic patient. Prick-test and RAST to FB latex were positive and removal of the ficus plant resolved their symptoms confirming the etiologic role of the plant. The patient did not demonstrate sensitization to other common allergens (except weeds) involved in respiratory (latex of Hevea brasiliensis, mites...) and food allergies (negativity of the prick-tests for fig, avocado, banana, kiwi). Now, FB is a new hidden allergen in the house. Questionning for its presence and testing it should be considered; as it should be introduced in the standard prick-test panel.

Intravenous chemotherapy, early debulking surgery, and consolidation intraperitoneal chemotherapy in advanced ovarian carcinoma.

OBJECTIVE: The efficacy of a cisplatin-anthracycline combination, early debulking surgery, and intraperitoneal chemotherapy has been demonstrated through separate studies. We evaluated a multimodal treatment strategy integrating these therapeutic options. METHODS: Women with stage III or IV ovarian carcinoma received six cycles of cisplatin/epirubicin alternating with leucovorin and 5-fluorouracil. Patients with a residual disease (RD) measuring more than 2 cm after the initial laparotomy underwent an early debulking surgery after the first three cycles of chemotherapy. A second-look laparotomy (SLL) was performed after six cycles of intravenous chemotherapy. Intraperitoneal chemotherapy with cisplatin, VP16, and mitoxantrone was then administered in patients with no or RD < 2 cm after SLL. RESULTS: A total of 87 patients were included. After initial laparotomy, 11 patients (12%) had no macroscopic residual disease, 38 (44%) had a RD < or =2 cm, and 38 (44%) had a RD > 2 cm. After early debulking surgery, an additional 18 patients (21%) had a RD < 2 cm. Seventy-five patients were evaluable for response to intravenous chemotherapy: the overall response rate was 80%, and 30 patients achieved a pathological complete response (40%). Eight percent of the patients had stable disease and 12% had a progression. Sixty-eight patients received intraperitoneal chemotherapy after second-look laparotomy. With a 72-month median follow-up, median overall survival and progression-free survival were, respectively, 37 and 19 months. Five-year survival was 41%. CONCLUSION: The prognosis of patients with advanced ovarian carcinoma may be improved by a sequential treatment strategy including intravenous chemotherapy, early debulking surgery, and intraperitoneal chemotherapy.

Evaluation of oxaliplatin dose intensity in bimonthly leucovorin and 48-hour 5-fluorouracil continuous infusion regimens (FOLFOX) in pretreated metastatic colorectal cancer. Oncology Multidisciplinary Research Group (GERCOR).

BACKGROUND: Studies of bimonthly 48-hour regimens of high-dose leucovorin (LV) (FOLinic acid), 5-fluorouracil (5-FU) by continuous infusion combined with OXaliplatin (FOLFOX) in pretreated patients with metastatic colorectal cancer suggest that oxaliplatin dose intensity is an important prognostic factor for response rate and progression-free survival (PFS). To help define the optimal dose schedule for oxaliplatin in pretreated metastatic colorectal cancer, we retrospectively analyzed data from three phase II studies using different FOLFOX regimens (FOLFOX2, 3 and 6). PATIENTS AND METHODS: Data on 126/161 patients were analyzed. FOLFOX2 included oxaliplatin 100 mg/m2; FOLFOX3, 85 mg/m2; and FOLFOX6, 100 mg/m2 (added to a simplified LV-5-FU regimen), all as two-hour infusions. A total of 47 patients received low dose intensity oxaliplatin (LDI: < or = 85 mg/m2/2 weeks) and 79 patients high dose intensity oxaliplatin (HDI: > 85 mg/m2/2 weeks). RESULTS: Objective responses occurred in 31 (39%) HDI patients and 9 (19%) LDI patients (P = 0.03). Median PFS was 28 weeks, with 52% of HDI patients progression free at 6 months, and 26 weeks with 36% of LDI patients progression free at six months (P = 0.02). Increased oxaliplatin dose intensity was not associated with increased neurotoxicity or other toxicities. FOLFOX are among the most effective regimens for treating LV-5-FU-resistant metastatic colorectal cancer. CONCLUSIONS: This study shows that oxaliplatin dose intensification significantly improves response rate and PFS in pretreated metastatic disease without increasing severe toxicity.

Oxaliplatin added to the simplified bimonthly leucovorin and 5-fluorouracil regimen as second-line therapy for metastatic colorectal cancer (FOLFOX6). GERCOR.

For patients resistant to leucovorin (LV) and 5-fluorouracil (5-FU), the addition of oxaliplatin (85 or 100 mg/m2) to bimonthly LV-5-FU has given a response rate of 20-46%. The highest response rate has been observed with oxaliplatin 100 mg/m2 (FOLFOX2). The present phase II study (FOLFOX6) infused oxaliplatin (100 mg/m2) with LV (400 mg/m2) as a 2-h infusion on day 1, followed by bolus 400 mg/m2 and a 46-h infusion (2.4-3 g/m2) of 5-FU, every 2 weeks. Among the 60 patients treated, 16 (27%) had partial responses (95% confidence interval: 15-38), 27 (45%) had stable disease, 15 (25%) experienced disease progression and 2 (3%) had non-measurable disease. From the start of FOLFOX6, median progression-free survival was 5.3 months and median survival 10.8 months. From the 448 cycles analysed, NCI-CTC grade 3-4 toxicities per patient were: peripheral neuropathy 16%, nausea 7%, diarrhoea 7%, mucositis 5%, neutropenia 24%, thrombocytopenia 2%. Overall 26 (46%) patients experienced grade 3-4 toxicities. Because of toxicity, only 36% of the patients received > or = 90% of the scheduled oxaliplatin dose intensity. FOLFOX6 was active in pretreated patients resistant to LV-5-FU and is being investigated as first-line therapy. We are now investigating FOLFOX7, a regimen with a higher oxaliplatin dose intensity and a lower 5-FU dose.

[Angiosarcoma of the breast. Apropos of 8 cases and review of the literature]. / Les angiosarcomes du sein. Etude de 8 cas et revue de la littérature.

The 8 cases of primary breast angiosarcoma which were diagnosed, treated and had their follow-up at the Gustave-Roussy Institute between 1954 and 1995 are reported. The age at presentation ranged from 32 to 68 years. In 4 patients the vascular nature of their mammary lesion was conspicuous by a violaceous discolorations of the overlying skin. No patient had enlarged ipsilateral axillary lymph nodes. One patient had metastases. In 2 out of 5 patients who had a partial surgical or fine-needle biopsy before treatment, the diagnosis was missed, and adequate treatment was unduly delayed. The tumor most often presents as an ill defined area made of dense endothelium-lined papillae. A remarkable picture of "soap bubbles" has been identified in 4 cases. The "meshes" of fatty areas appear to be reinforced as they are infiltrated by tumor cells. This appearance may be specific of mammary angiosarcoma. By the French Cancer Centers' grading system for soft tissue sarcomas in general, grade is III in 3 tumors, II in 2 tumors, I in 3 tumors. Five tumors were treated by total mastectomy only. In 3 cases a total mastectomy was followed by radiation therapy to the chest wall. At diagnosis a chemotherapy was administered only to the patient who had metastases. Median disease-free survival was 9 months. Median overall survival was 13 months. From a review of the literature a simple mastectomy appears to be necessary as well as enough for local treatment. Patients with a grade III angiosarcoma of the breast should be included into a therapeutical trial of adjuvant chemotherapy for soft tissue sarcomas in general.

[Large granular T-cell lymphocytic leukemia disclosed by bilateral uveitis: association with celiac disease]. / Leucémie à grands lymphocytes granuleux T révélée par une uvéite bilatérale: association à une maladie coeliaque.

A 70-year-old woman presented with bilateral anterior uveitis. She was on a gluten-free diet because of a celiac disease which had been diagnosed 3 months before. An anterior chamber aspirate contained a majority of large granular lymphocytes (LGL). The investigation of a chronic neutropenia led to the diagnosis of an otherwise typical T-LGL leukemia. This seems to be the first report of a CD3+ CD4- CD8+ T-LGL leukemia causing anterior uveitis through infiltration of leukemic cells, and the second report of an intriguing association of celiac disease with T-LGL leukemia.

[Modulation of 5-fluorouracil with folinic acid in advanced colorectal cancers. Groupe d'étude et de recherche sur les cancers de l'ovaire et digestifs (GERCOD)]. / La modulation du 5-fluorouracile par l'acide folinique dans les cancers colorectaux avancés. Groupe d'étude et de recherche sur les cancers de l'ovaire et digestifs (GERCOD).

The rational of leucovorin modulation of 5-fluorouracil and the clinical results in colorectal cancer are reviewed with special emphasis on the monthly schedule of low dose leucovorin and 5FU bolus for 5 consecutive days (NCCTG-Mayo Clinic regimen) and the bimonthly schedule of high-dose leucovorin and 5FU bolus plus continuous infusion for two consecutive days (LV5FU2) which is now considered as a new standard.

[Oxaliplatin, folinic acid and 5-fluorouracil (folfox) in pretreated patients with metastatic advanced cancer. The GERCOD]. / Oxaliplatine, acide folinique et 5-fluorouracile (folfox) en seconde ligne thérapeutique du cancer colorectal métastasé. Le GERCOD.

Preliminary studies suggest synergy between oxaliplatin and fluorouracil (5-FU). To assess this issue, we performed a study in pretreated patients with advanced colorectal cancer (CRC) resistant to leucovorin and 5-FU. Regimen consisted of oxaliplatin day 1, 130 mg/m2 every two cycles (folfox 1) or 100 mg/m2/cycle (folfox 2) or 85 mg/m2/cycle (folfox 3) and leucovorin 500 mg/m2 as a 2-hour infusion, followed by 5-FU 22 h infusion 1.5-2 g/m2 for two consecutive days every 2 weeks. One hundred and thirteen patients have been treated. One complete response (CR) and 32 partial responses (PRs) were observed for an overall response rate of 29.2%. Sixty-seven patients had prior documented progression while receiving the same schedule of leucovorin and 5-FU than the one used in the folfox regimens, among them 18 had PRs (26.9%). The best response rate was observed in patients treated with the folfox 2 regimen: 41.7%. From start of folfox, median progression-free survival was 6 months and median survival 13 months. Limiting toxicities were peripheral neuropathy and neutropenia. Fifty-four percent of the patients experienced WHO toxicity > or = grade 3 with the folfox1 regimen, 45% with the folfox2 and 40% with the folfox3. The folfox regimens achieve a high response rate in pretreated patients with CRC. Further studies are needed to determine the best oxaliplatin dose-intensity.

[Locoregional recurrences of breast cancer]. / Récidives loco-régionales de cancers du sein.

AIM OF THE STUDY: To determine the characteristics of 51 cases of isolated local regional breast cancer recurrence. METHODS: Retrospective study from 1980 to 1992, survival calculated according to Kaplan-Meier and log-rank test. RESULTS: Twenty-five patients had had a conservative treatment of her primary tumour, 26 had been treated by modified radical mastectomy. Local regional recurrence rate was 9%: 44% of recurrences after lumpectomy and 43% of recurrences after mastectomy occurred within 2 years after the initial treatment. Site of local regional recurrence was chest wall only (16 cases), breast only (15 cases) or axillary or supraclavicular node with or without chest wall or breast involvement (20 cases). The actuarial 5-year survival rate after recurrence is 54%. It depends on the time to recurrence (40% if time to recurrence was less than 2 years, 68% if more than 2 years, p < 0.10), on initial node involvement (36% for N+, 71% for N-, p < 0.15) and on the site of recurrence (chest wall: 43%; breast: 48%; regional node: 12%, p < 0.10). CONCLUSION: Like in the literature, severe recurrences are early recurrences, lymph node recurrences and recurrences following a primary tumour with involved axillary nodes.
