PJP after transplant (TX) is associated with substantial morbidity and mortality. In the present era of universal and routine implementation of PJP prophylaxis (PPX) during the initial 6 to 12 months after TX, usually with trimethoprim-sulfamethoxazole (TMP-SMX), identifying risk factors for its occurrence can help identify patients who remain at increased risk, and therefore are most likely to benefit from ongoing PPX.
At our program, all kidney and/or pancreas TX recipients routinely receive prophylactic TMP-SMX for 12 months after TX. We reviewed 28 recipients who developed PJP any time after TX between 1994 and 2016. For comparison, 3 recipients without PJP matched on time from TX were identified for each case.
Median time to PJP diagnosis was 4.6 years (IQR: 1.4-9.6 years). Three patients developed PJP in the first year after PPX was stopped prematurely due to adverse effects. Recipients who developed PJP were older at time of TX (51.7 vs 46.2 years; p=0.05) and were more likely to be non-Caucasian (25.0 vs 9.5%; p=0.07), have received deceased TX (67.9 vs 52.4%; p=0.15), have higher number of HLA mismatches (82.1 vs 61.9% had ≥3/6, 3 being the median for the entire group; p=0.08), have prior history of BK viremia of at least 1000 copies/mL (21.4 vs 6.0%; p=0.01), CMV viremia (35.7 vs 6.0%; p<0.001), invasive fungal infections (7.1 vs 1.2%; p=0.01) and diarrheal illnesses due to Clostridium difficile or norovirus (10.7 vs 2.4%; p=0.1). T-cell depleting induction use, repeat TX, DGF and rejection rates were similar between the two groups. After multivariable adjustment, prior history of CMV viremia (odds ratio [OR] 6.5; p=0.001) and of invasive fungal infections (OR 2.6, p=0.006) remained significantly associated with subsequent diagnosis of PJP. PJP was associated with high mortality (32.1%) and worse graft survival (p=<0.001).
We recommend continuation or re-initiation of PJP PPX after the first year for kidney and pancreas TX recipients if their course is complicated by CMV viremia or invasive fungal infections.
