Pulmonary Alveolar Proteinosis Refractory to Plasmapheresis and Rituximab despite GM-CSF Antibody Reduction.

We share our experience of a patient with pulmonary alveolar proteinosis who was refractory to plasmapheresis and rituximab despite a significant reduction in the offending antibody. He presented with shortness of breath, fevers, chills, and sweats for 4 months. He was diagnosed with autoimmune PAP based on typical radiology findings, bronchoalveolar fluid analysis, and elevated anti-GM-CSF levels. Given his limited improvement with whole lung lavage and inhaled GM-CSF therapy, he underwent two series of plasmapheresis. Series one was 5 procedures in 6 days, and series two was 5 procedures in 9 days followed by rituximab. These did not appear to provide any lasting clinical benefit in the year after plasmapheresis despite a marked decrease in serum anti-GM-CSF levels. However, about a year after plasmapheresis, he went into remission and has not required any treatment.

When Eating Becomes Torturous: Understanding Nutrition-Related Cancer Treatment Side Effects among Individuals with Cancer and Their Caregivers.

Individuals living with cancer often experience multiple nutrition-related side effects from cancer treatment, including changes in taste and smell, nausea, diarrhea, loss of appetite, and pain during eating. These side effects can profoundly impact nutritional status and quality of life. The purpose of this study was to explore experiences with nutrition-related cancer treatment side effects among cancer patients and their family caregivers, the way they manage such side effects, and the resulting changes in food preferences and behaviors. Structured surveys and in-depth interviews were conducted. Interviews focused on the presence and management of treatment side effects, how those changes influenced food preferences, and the extent to which they interfered with quality of life. Most patients (72%) reported treatment side effects; 61% reported that these side effects impacted their eating and drinking. Common side effects included fatigue (58%), dry mouth (30%), nausea (24%), constipation (20%) and diarrhea (20%). Six overarching qualitative themes were identified: Spiral of side effects; Pain of eating; Burden of eating; Loss of taste/change in taste; Symptom management; and Solutions. The authors conclude with implications for food and nutrition practice-moving beyond traditional recommendations of what to eat or avoid-to consider the overall patient and caregiver experience.
