[Should we suspect immune deficiency in internal medicine hospitalized patients?] / Quand suspecter une immunodéficience chez le patient hospitalisé en médecine interne?

Although often overlooked immune deficiencies are more common than generally believed. The internist is frequently the first physician to potentially meet affected patients, playing a significant role in detecting these immune deficiencies, whether they are primary (congenital) or secondary (acquired). In both scenarios, early identification and intervention can greatly reduce the morbidity and mortality of these patients. In this article, we review common immune deficits, suggest initial assessments when indicative signs are present, and provide guidance for management.

Les déficits immunitaires, quoique souvent méconnus, sont plus fréquents qu'on ne le pense. L'interniste est fréquemment le premier médecin à entrer en contact avec des patients potentiellement atteints, jouant ainsi un rôle important dans la détection de ces maladies, qu'elles soient primaires (congénitales) ou secondaires (acquises). Dans les deux cas, une identification et une intervention précoces peuvent considérablement réduire la morbidité et la mortalité de ces patients. Dans cet article, nous passons en revue les déficits immuns fréquents, suggérons des bilans initiaux en présence de signes évocateurs et fournissons des orientations pour la prise en charge.

Risk stratification for hospital-acquired venous thromboembolism in medical patients (RISE): Protocol for a prospective cohort study.

BACKGROUND: Hospital-acquired venous thromboembolism (VTE) is one of the leading preventable causes of in-hospital mortality. However, its risk assessment in medically ill inpatients is complicated due to the patients' heterogeneity and complexity of currently available risk assessment models (RAMs). The simplified Geneva score provides simplicity but has not yet been prospectively validated. Immobility is an important predictor for VTE in RAMs, but its definition is inconsistent and based on subjective assessment by nurses or physicians. In this study, we aim to prospectively validate the simplified Geneva score and to examine the predictive performance of a novel and objective definition of in-hospital immobilization using accelerometry. METHODS AND ANALYSIS: RISE is a multicenter prospective cohort study. The goal is to recruit 1350 adult inpatients admitted for medical illness in three Swiss tertiary care hospitals. We collect data on demographics, comorbidities, VTE risk and thromboprophylaxis. Mobility from admission to discharge is objectively measured using a wrist-worn accelerometer. Participants are followed for 90 days for the occurrence of symptomatic VTE (primary outcome). Secondary outcomes are the occurrence of clinically relevant bleeding, and mortality. The evolution of autonomy in the activities of daily living, the length of stay, and the occurrence of readmission are also recorded. Time-dependent area under the curve, sensitivity, specificity, and positive and negative predictive values are calculated for each RAM (i.e. the simplified and original Geneva score, Padua, and IMPROVE score) with and without the objective mobility measures to assess their accuracy in predicting hospital-acquired VTE at 90 days. ETHICS AND EXPECTED IMPACT: The ethics committee approved the protocol and the study was registered on ClinicalTrials.gov as NCT04439383. RISE has the potential to optimize VTE risk stratification, and thus to improve the quality of care of medically hospitalized patients.

[The Internal medicine articles that struck us the most in 2021]. / Année 2021 mise en perspective par les internistes hospitaliers.

The year 2021 has seen many breakthroughs in general internal medicine, despite the ongoing COVID-19 pandemic, with multiple implications in our daily clinical practice. From shorter antibiotic treatment duration in community-acquired pneumonia, to new indications for colchicine treatment, without forgetting better targets of hemoglobin for transfusion, questioning of the interest of high dose vitamin D substitution when preventing falls in older patients and finally disappointing hopes for new indications of albumin substitution in cirrhosis, the literature is full of new evidence. Each year, the chief residents of the internal medicine ward in Lausanne university hospital (CHUV) in Switzerland meet up to share their readings: here is a selection of ten articles, chosen, summarized, and commented for you.

L'année 2021, malgré la pandémie de Covid-19, a vu de nombreux progrès en médecine interne générale, avec de multiples implications pour notre pratique quotidienne. D'une durée diminuée d'antibiothérapie pour le traitement de la pneumonie communautaire à de nouvelles indications au traitement de colchicine, en passant par des précisions sur les cibles de transfusion érythrocytaire, ainsi qu'une remise en question de l'intérêt de la vitamine D à haute dose dans la prévention des chutes chez la personne âgée, et pour finir des espoirs déçus de nouvelle indication à la substitution d'albumine dans la cirrhose, les nouveautés abondent dans la littérature. Chaque année, les cheffes et chefs de clinique du Service de médecine interne du CHUV se réunissent pour partager leurs lectures : voici une sélection de dix articles choisis, revus et commentés pour vous.
