Our series consisted of 1700 patients (836 females, 49.2%; 864 males,
50.8%) with an average age of 48.23 ± 16.68 (range: 18-93). A total of
479 patients (28.4%) had comorbidities. As for the prognostic outcome,
mortality was reported in 32 patients (2.0%), and the length of
hospitalization was 5.03 ± 3.60 days (range: 0-32 days) (Table
1 ).
As shown in Table 2 , the
impacts analysis of demographic and clinical variables on survival
yielded that advanced age (p<0.001), presence of at least 1
comorbid disease (p=0.045), increased length of hospitalization
(p=0.006), elevated white blood cell (p=0.001) and neutrophil (p=0.002)
counts, increased serum levels of glucose (p=0.027), blood urea nitrogen
(p<0.001), AST (p=0.006), LDH (p<0.001), CRP
(p>0.001), and D-dimer (p=0.001). In contrast, diminution
of serum levels of albumin (p<0.001), ALT (p=0.028), calcium
(p=0.022), and platelet count (p=0.010) were associated with increased
mortality (Table 2 ).
Table 3 demonstrates the relationship between clinical
variables and length of hospitalization. We noted that there was a
positive and weak relationship between serum D-dimer levels and length
of hospitalization (r=0.322, p<0.001; Table 3 ).
The performances of clinical variables for the estimation of prognostic
outcomes are shown in Table 4. Accordingly, the variables with
the highest potential to estimate survival were creatinine (93.7%),
D-dimer (88.9%), blood urea nitrogen (87.2%), neutrophil count
(80.9%), and LDH (75.9%), respectively. Lower levels of albumin,
calcium, salt, and lymphocyte count in the blood were all linked to an
increased risk of death (Table 4 ).
