A summertime pause in immunoglobulin replacement therapy: a prospective real-world analysis

Aim: To describe the effects of a summertime pause (SP) in immunoglobulin replacement therapy (IgRT). Patients & methods: We conducted a prospective single-center observational study, including 44 patients undergoing intravenous IgRT between May and June 2019 in a French teaching hospital. Results: IgRT was interrupted in 23 patients from June to October. Patients who underwent an SP were older, more likely to have secondary immunodeficiency (SID) and received lower doses of immunoglobulin and more antibiotics during winter. Most patients who did not undergo an SP had severe primary immunodeficiency. The SP did not increase the risk of infection, improved the quality of life and reduced treatment costs. Conclusion: SP in IgRT is a safe practice and should be considered for patients with mild SID. Lay abstract Immunoglobulin replacement therapy (IgRT) is an expensive treatment used to prevent infections in patients with immunodeficiency. Becauase most of the infections occur during winter, it is sometimes possible to interrupt IgRT during summer. In our study between May and October 2019, the 23 patients who underwent a summertime pause (SP) did not have more infections than the 21 who did not; the former also described an improvement in their quality of life. However, the physicians proposed SP to patients with a specific type of immunodeficiency, with fewer infections during winter and lower doses of IgRT. We report here for the first time the safety and benefits of a summertime pause in IgRT, for selected patients with less severe immunodeficiency. en

Myasthenia gravis and paroxysmal nocturnal hemoglobinuria after thymectomy: A rare association

Abstract Paroxysmal nocturnal hemoglobinuria (PNH) is a very rare clonal autoimmune disease manifesting with hemolysis, thrombosis, or bone marrow failure. We present an atypical association of myasthenia gravis, aplastic anemia, and PNH occurring years after thymectomy. While this association might be extremely rare, it may not be coincidental as there is a common pathophysiology between PNH and aplastic anemia, with the latter reported in several thymoma/thymectomy cases. Eculizumab was introduced with good efficacy and without safety concern in our patient, leading to long‐term control of PNH without worsening of myasthenia gravis

Time to treatment initiation and HIV viral suppression in people diagnosed with HIV-1 during COVID-19 pandemic in ex-Aquitaine, France (ANRS CO3 AQUIVIH-NA Cohort-QuAliCOV Study)

International audienceThe Covid-19 pandemic's impact on initiation and effectiveness of antiretroviral therapy (ART) in people diagnosed with HIV remains unclear. We evaluated critical delays in HIV care in people diagnosed before and during the pandemic in ex-Aquitaine, France. We considered adults diagnosed with HIV-1 in 2018-2021 and enrolled in the ANRS CO3 AQUIVIH-NA and followed them until 10/10/2022 for those diagnosed during the pandemic (1/4/2020 - 31/12/2021) and until 31/03/2020 for historical controls. We compared their characteristics at inclusion and the median time between diagnosis and ART initiation, ART initiation and viral suppression and diagnosis and virological suppression (effective management). 83 individuals were diagnosed during the pandemic versus 188 during the pre-pandemic period. Median follow-up was 549 (IQR: 329-713) days. Populations were similar in terms of sex, age, HIV transmission group, hospital type, and clinical characteristics at diagnosis, however, fewer were foreign-born during the pandemic (15.7% versus 33.5%, p=0.003). The probability of ART initiation, therapeutic success, effective management was higher in PLWH diagnosed during the pandemic in adjusted analyses (HR 2.0 95%CI. 1.5-2.7, HR 1.7 95%CI. 1.2-2.3, HR 1.8 95%CI. 1.3-2.6, respectively). Those diagnosed during the pandemic were 2.3 (95%CI: 1.2-4.1) times more likely to be virologically suppressed within 6 months of diagnosis compared to historical controls. Pandemic-related reorganizations may have resulted in newly diagnosed PLWH being prioritized, however, the lower proportion of foreign-born PLWH diagnosed during the pandemic period, likely due to reduced migration and potential delays in diagnosis, may contribute to these preliminary findings

Cognitive disorders in HIVinfected patients: are they HIV-related? AIDS 27: 391–400. doi: 10.1097/QAD.0b013e32835b1019 PMID: 23079813

for the ANRS CO3 Aquitaine Cohort Objectives: Large unselected studies on representative samples of HIV-infected patients with a whole battery of neuropsychological tests and cerebral MRI scan are required to assess the frequency of neurocognitive impairment (NCI), the determinants of mild neurocognitive disorders (MNDs), or HIV-associated dementia (HAD) and the relationship between NCI and MRI scan findings. Methods: Investigation of 400 consecutively enrolled HIV-1-infected adults from the ANRS CO3 Aquitaine Cohort, using standardized neurocognitive tests chosen to achieve consistency with Frascati's criteria. Half of the patients had a cerebral MRI scan allowing gray and white matter volume measurement. Factors associated with NCI were studied by logistic regression models. Results: Median age of participants was 47 years, 79% were male and 89% received combination antiretroviral treatment (cART), of whom 93% had plasma HIV RNA below 500 copies/ml. Median CD4 cell count was 515 cells/ml. Prevalence of NCI was 59%, including 21% of asymptomatic NCI, 31% of MND, and 7% of HAD. A low level of education, prior neurologic AIDS-defining disorders event, anxiety, depressive symptoms, and prior history of brain damage were independently associated with MND or HAD, but neither HIV nor cART-related variables. The presence of NCI was significantly associated with lower gray matter fraction. Interpretation: In this large unselected cohort, a high prevalence of symptomatic neurocognitive disorders was mainly related to its traditional determinants and associated with gray matter atrophy at early stages of the disease
