[Hodgkin lymphoma in the elderly]. / Le lymphome de Hodgkin chez le sujet âgé

We report a case of Hodgkin's lymphoma in a patient aged 75, presenting with acute cardiopulmonary insufficiency, hospitalized in a geriatrics ward. The deterioration of his general condition and the discovery of several lymph nodes led us to perform an aspiration of a lymph node and a bone marrow biopsy. Reed-Sternberg cells, pathognomonic of Hodgkin's disease were identified on the smears and biopsy sections. Due to the poor condition of the patient, it was decided not to treat with chemotherapy. The diagnostic approach and treatment strategy of Hodgkin's disease are summarized in this paper, especially the particular features of the disease in the elderly.

Reversal of overanticoagulation in very elderly hospitalized patients with an INR above 5.0: 24-hour INR response after vitamin K administration.

BACKGROUND: Reversal of overanticoagulation to minimize the bleeding risk is important in elderly inpatients receiving vitamin K antagonist therapy. However, no study has specifically focused on this population. The objective of this study is to evaluate whether guidelines based on American College of Chest Physicians recommendations for the management of overanticoagulation (international normalized ratio [INR] ≥5.0) can apply to elderly inpatients, and notably allow 24-hour INRs to return to the 1.8-3.2 range in this population. The influence of different factors on the vitamin K response also was evaluated. METHODS: Inpatients aged ≥75 years with INR ≥5.0 were included in this observational study. INRs were assessed on the day of the overdosage (Day 0) and on the following day (Day 1). RESULTS: Of 385 Day 0 INRs ≥5.0 (239 patients; 86±6 years), 217 were managed according to recommendations, with a mean INR decreasing from 6.8±2.4 (range: 5.0-20.0) on Day 0 to 2.7±1.3 (range: 1.1-10.1) on Day 1 (P<.0001); 55% of INRs were within the 1.8-3.2 range, 20% <1.8, and 25% >3.2. In the subset of Day 0 INRs between 5.0 and 6.0, mean INR decreased from 5.5±0.3 to 2.7±1.0 (P<.0001) on Day 1 after oral administration of 1 mg vitamin K1 (n=121) and from 5.3±0.3 to 5.0±1.6 (P=.149) without vitamin K1 administration (n=48). Among covariates entered in the multivariate analysis, including co-medications, only the vitamin K1 dose influenced Day 1 INRs, with higher doses of vitamin K1 associated with Day 1 INRs <1.8 (P<.0001). CONCLUSION: In elderly inpatients with INR ≥5.0, both vitamin K antagonist dose omission and vitamin K1 administration according to recommendations were effective in reversing overanticoagulation, allowing most INRs to return to the 1.8-3.2 range without excessive overcorrection. Therefore, American College of Chest Physicians recommendations may be applied to elderly inpatients.

[Elderly patients with myelodysplastic syndrome with del 5q receiving lenalidomide: two case reports with poor prognosis]. / Patients âgés atteints de syndrome myélodysplasique avec anomalie 5q- traités par lénalidomide : à propos de deux observations avec évolution défavorable.

We report two cases of myelodysplastic syndrome (MDS) with del(5q) isolated cytogenetic abnormality in elderly patients: AREB-1 in Patient 1, "5q syndrome" in Patient 2. A first line of treatment including hematopoietic growth factors (darbepoetin alone or associated with G-CSF) failed after several months and a treatment with lenalidomide was initiated in both cases. The treatment was poorly tolerated (myelosuppression) in Patient 1 without an improvement of the quality of life; a progression of the disease was observed with an increase of the bone marrow blastosis and a new acquired karyotypic abnormality (t13;17), leading to the prescription of 5-azacytidine. Patient 2 had a good response to lenalidomide for several months with an increase in the haemoglobin level and a transfusion independence. The patient's prognosis suddenly worsened with the occurrence of a blood blastosis (10%): 5-azacytidine was thus initiated. These two case reports illustrate the recent advances in the management of patients with MDS with del(5q), including the use of lenalidomide.
