The long-term prognosis following lung transplantation (LTX) depends mainly
on the development of chronic rejection which appears clinically as
deterioration of the lung function while, histologically, obliterative
bronchiolitis (OB) is found. However, it still remains questionable whether
heart-lung (HL), double or single lung (DL/SL) transplants behave similarly
with regard to incidence and time pattern. Eighty-two patients,
transplanted until August 92, were analyzed. Early and late deaths within
180 days postoperatively were excluded. A total of 64 patients at risk
could be evaluated. By repeated lung function tests, obstructive airway
disease was defined by a drop of 25% or more of the forced expiratory
volume in one second (FEV1) in percent of the inspiratory vital capacity.
Results: The functional optimum after transplantation was reached after a
comparable time-span postoperatively in all groups. Chronic deterioration
of the lung function developed earlier following DLTX compared to HLTX and
SLTX. Obstructive airway disease was diagnosed in 9/20 (45%) HL, 7/19 (37%)
DL, and 7/25 (28%) SL patients. Of these, 4 died and 4 had to be
retransplanted for the disease while an additional 15 patients are
currently under investigation. It is concluded that the development of
obstructive airway disease represents a serious problem in all types of
lung transplantation. There is a tendency to earlier development following
DLTX--perhaps caused by the greatest immunological potential in this group
of patients.
