Background/Purpose:

Alveolar hemorrhage (AH) is a rare and severe manifestation of systemic lupus erythematosus (SLE). Therefore, the aim of this study was to compare characteristics of AH in juvenile (JSLE) and adult SLE (ASLE) patients.

Methods:

from January 1990 to January 2010, 28 out of 1785 SLE patients (13 JSLE and 15 ASLE) had AH in our tertiary hospital.

Results:

JSLE and ASLE had comparable disease duration (2.6 ± 3.0 vs. 5.6 ± 7.0 years, p=0.151) with the mean age at AH diagnosis of 15.3 ± 2.7 and 28.7 ± 10.3 yrs for JSLE and ASLE, respectively. The frequency of AH events was significantly higher in JSLE [4.94% (13/263)] compared to ASLE patients [0.99% (15/1522)], p<0.001 and it was diagnosed at SLE onset in two (15.4%) JSLE and six (40.0%) ASLE patients p=0.221). Before AH event, the JSLE patients were using a higher mean dose of prednisone (>0.5mg/kg/day) when compared to ASLE 54%vs. 15%, p=0.042). Macrophage activation syndrome with macrophage hemophagocytosis was only observed in JSLE compared to ASLE patients with AH diagnosis (23%vs. 0%, p=0.087). Regarding outcomes, frequencies of death were significantly higher in JSLE than ASLE patients (69%vs. 13%, p=0.006), with a trend of higher frequency of mechanical ventilation use (85%vs. 47%, p=0.055). In spite of that, the mean drop of hemoglobin was significantly lower in JSLE patients (2.9 ± 0.9 vs. 5.5 ± 2.9 g/dL, p=0.006). All other demographical, clinical and laboratory features were alike in both groups (p>0.050).

Conclusion:

This study revealed that AH is more prevalent in juvenile lupus with a worse outcome compared to adult SLE patients.
