Renal grafts from anti-hepatitis B core-positive donors: a quantitative review of the literature.
Organ shortage is a major problem in transplantation. The use of organs from hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody (HBcAb)-positive donors could significantly increase the donor pool. However, little information is available about the impact of HBcAb status of renal donors on viral transmission to recipients. To address this issue, the present quantitative review of relevant studies has been performed. ⋯ Our review indicates that the risk of HBV transmission from HBcAb-positive kidney donors is extremely low. Therefore, kidneys from these donors can be transplanted safely into ESRD patients.

Bronchiolitis obliterans syndrome (BOS) can have either an acute or chronic onset with an abrupt or insidious course. The diagnosis is typically achieved by physiological criteria with development of a sustained decline in expiratory flow rates for at least 3 weeks. We review the rapid development of acute BOS and bronchiectasis after respiratory syncytial virus infection in a lung transplant recipient, who had been doing well with normal pulmonary function for 3 years after lung transplantation.

Diarrhea is a frequent and potentially severe complication in solid organ transplant (SOT) recipients. One of the most common infectious etiologies of diarrhea in these patients is Clostridium difficile. Our objective was to investigate the association of C. difficile infection (CDI) with the outcomes of hospitalized SOT patients. ⋯ Our results demonstrate that CDI is associated with overall significantly worse outcomes in hospitalized patients with SOT.

The incidence of infection with non-tuberculous mycobacteria (NTM) after lung transplant is insufficiently defined. Data on the impact of NTM infection on lung transplant survival are conflicting. ⋯ Episodic isolation of NTM from lung transplant recipients is common. Most isolates occur among asymptomatic patients and are transient. Rapidly growing NTM can cause significant SSI, which may be difficult to cure. NTM disease rate is higher among lung transplant recipients than in the general population. In this cohort, NTM isolation was not associated with increased post-transplantation mortality.

Solid organ transplant (SOT) recipients are at risk for Pneumocystis pneumonia (PCP), especially in the first year post transplant. Although trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis substantially decreases this risk, there is little data or consensus on optimal duration of prophylaxis. Consequently, there is lack of standardization of prophylaxis duration (3 months to lifelong, depending on organ group) in SOT programs. ⋯ Our experience with late PCP cases in lung transplant recipients receiving only 1 year of prophylaxis lends support to prolonged PCP prophylaxis in this group. Given the number of patients who had experienced an acute rejection episode or CMV disease preceding PCP in non-lung SOT recipients, consideration should be given to re-institution of PCP prophylaxis for a period of time after these events in kidney, kidney/pancreas, and liver transplant recipients.
