Intravenous immunoglobulin in heart transplant recipients with mild to moderate hypogammaglobulinemia and infection.

Background: Hypogammaglobulinemia (HGG) is a complication of solid organ transplantation leading to increased risk of infections. Intravenous immunoglobulin G (IVIG) replacement in patients with HGG may be able to reduce risk and morbidity associated with infection; however, there is scarce data about IVIG in mild to moderate HGG (IgG 400-700 mg/dl) and heart transplant recipients.

Methods: A single center, retrospective study was performed in heart transplant recipients with mild (IgG 500-700 mg/dl) to moderate (IgG 400-499 mg/dl) HGG in the presence of an infection.

Anti-peptidylarginine deiminase-4 antibodies at mucosal sites can activate peptidylarginine deiminase-4 enzyme activity in rheumatoid arthritis.

Background: Mucosal sites are hypothesized to play a role in the development of rheumatoid arthritis (RA). Since serum anti-peptidylarginine deiminase (PAD)4 antibodies, including a subset that cross-react with PAD3 (PAD3/4), are specific for RA and associate with severe disease, we sought to examine whether anti-PAD4 and anti-PAD3/4 antibodies were present in the lung and oral mucosa of subjects with RA and "at-risk" for RA.

Methods: We included 37 RA, 25 healthy control, and 46 subjects "at-risk" for RA based on familial RA and/or serum anti-citrullinated protein antibody (ACPA) positivity.

Patient-reported outcomes in light of supportive medications in treatment-naïve lung cancer patients.

Purpose: The impact of supportive medications on patient-reported outcomes (PROs) has not been systematically evaluated. We describe the supportive medications used by treatment-naïve lung cancer patients and assess their association with PROs from MD Anderson Symptom Inventory (MDASI).

Methods: Treatment-naïve lung cancer patients who completed PROs from MDASI at the initial visit to MD Anderson Cancer Center were included.
