The impact of the housing status on clinical outcomes and health care utilization among individuals living with HIV

ABSTRACT

The lack of stable housing can impair access and continuity of care for patients living with human immunodeficiency virus (HIV). This study investigated the relationship between housing status assessed at multiple time points and several core HIV-related outcomes within the same group of HIV patients experiencing homelessness. Patients with consistently stable housing (CSH) during the year were compared to patients who lacked CSH (non-CSH group). The study outcomes included HIV viral load (VL), CD4 counts, and health care utilization. Multivariable and propensity weighted analyses were used to assess outcomes adjusting for potential group differences. Of 208 patients, 88 (42%) had CSH and 120 (58%) were non-CSH. Patients with CSH had significantly higher proportion of VL suppression and higher mean CD4 counts. The frequency of nurse visits in the CSH group was less than a half of that in the non-CSH group. Patients with CSH were less likely to be admitted to the medical respite facility, and if admitted, their length of stay was about a half of that for the non-CSH group. Our study findings show that patients with CSH had significantly better HIV virologic control and immune status as well as improved health care utilization.     

Radical radiotherapy in older patients with muscle invasive bladder cancer

Background

Muscle invasive bladder cancer (MIBC) is prevalent in the older patients, who are a vulnerable population with multiple co-morbidities and at increased risk of complications. Radical cystectomy is often not suitable, hence radical radiotherapy (RT) is an alternative option. We reviewed the outcomes of older patients treated with RT with or without concurrent chemotherapy (CRT) at our institution.

10-Year Heart Failure Outcomes From Nurse-Driven Clinics in Rural Sub-Saharan Africa

Nurse-led delivery care models have the potential to address the significant burden of heart failure in sub-Saharan Africa. Starting in 2006, the Rwandan Ministry of Health, supported by Inshuti Mu Buzima (Partners In Health–Rwanda), decentralized heart failure diagnosis and care delivery in the context of advanced nurse-led integrated noncommunicable clinics at rural district hospitals. Here, the authors describe the first medium-term survival outcomes from the district level in rural sub-Saharan Africa based on their 10-year experience providing care in rural Rwanda. Kaplan-Meier methods were used to determine median time to event for: 1) composite event of known death from any cause, lost to follow-up, or transfer to estimate worst-case mortality; and 2) known death only. Five-year event-free rates were 41.7% for the composite outcome and 64.3% for known death. While death rates are encouraging, efforts to reduce loss to follow-up are needed.     

A fatal case of bortezomib‐induced lung toxicity in a young adult heart transplant recipient

Bortezomib is approved for the treatment of multiple myeloma but increasingly used in heart transplant (HTx) recipients with antibody‐mediated rejection (AMR). Severe pulmonary toxicity is a rare complication in multiple myeloma patients treated with bortezomib, but has not been described in a solid organ transplant recipient. A 20‐year‐old man 7 years post‐HTx presented with acute rejection with hemodynamic compromise. Endomyocardial biopsy showed mixed rejection (ISHLT grade 2R‐3R acute cellular rejection (ACR) and pAMR 1 (I+) with diffuse C4d staining). Two new high MFI circulating MHC class‐II donor‐specific antibodies (DSA) were detected. Treatment included corticosteroids, antithymocyte globulin, plasmapheresis, IVIG, rituximab, and bortezomib (1.3 mg/m²). Due to rebound in DSA, a second course of bortezomib was started. Thrombocytopenia and peripheral neuropathy prompted a 50% dose reduction during the 2nd course. Shortly after the 3rd reduced dose, the patient developed hypoxemic respiratory failure. Bronchoscopy revealed pulmonary hemorrhage with negative infectious studies. Chest CT showed bilateral parenchymal disease with bronchiectasis and alveolar bleeding. Despite treatment with high‐dose steroids, severe ARDS ensued with multisystem organ failure. The patient expired 23 days after the final dose of bortezomib. Post‐mortem lung histology revealed diffuse alveolar damage, pulmonary fibrosis, and hemorrhage. Cardiac histology showed resolving/residual ACR 1R and pAMR 1 (I+). While rare, bortezomib‐induced lung toxicity (BILT) can occur in HTx recipients and can carry a high risk of mortality. Drug reaction and immediate drug withdrawal should be considered in patients who develop respiratory symptoms, though optimal management of BILT is unclear.
