Indicators of Male Gout Patients’ Comorbidities with the Theory on Traditional Chinese Medicine

Gout, typically manifesting as acute burning pain and swelling in a joint, has a high frequency of comorbidities. Based on Traditional Chinese Medicine syndrome (TCMS) theory, obstruction of dampness and heat syndrome (ODHS) and intermingled phlegm-stasis blood syndrome (IPSBS) were the two main TCMS subtypes in Chinese suffering from acute gout. In this study, we did a retrospective study enrolling 4,417 ODHS male gout cases and 1,413 IPSBS male gout cases, to investigate the comorbidities distribution difference between the two subtype groups and seek the potential indicators of male gout with some comorbidities. Interestingly, we found male ODHS group with higher prevalence of possible kidney damage (ODHS: 4.34%; IPSBS: 0.78%), lower prevalence of cardiac-cerebral vascular diseases (ODHS: 0.52%, IPSBS: 0.85%) and diabetes (ODHS: 1.06%; IPSBS: 1.63%) than male IPSBS group. And cystatin C is the only index reflecting that renal function showed significant difference between the two groups and the average levels were out of the normal range (1.09 ± 0.28 versus 1.17 ± 0.31, p=0.001). Further, we also observed significance difference on abnormality rates of cystatin C between the two groups. (χ2=5.543, p= 0.019). Besides, the comparison between the two subtypes also showed significant difference on hematocrit (43.12 ± 3.60 versus 42.26 ± 4.17%, p=0.007), mean corpuscular volume (89.52 ± 6.07 versus 86.81 ± 7.11fL, p=0.001), and mean corpuscular hemoglobin concentration (338.00 ± 11.67 versus 334.86 ± 13.58g/L, p=0.004). In general, we put forward that male gout patients with ODHS should be more vigilant of damage of renal function, and those with IPSBS should pay more attention to prevent cardiac-cerebral vascular diseases and diabetes. Increased Cys C level might be correlated with risk of comorbidities, especially diabetes . Thus, it is of significance to diagnose the TCMS in acute gout accurately and monitored related indices to prevent comorbidities.
