Abstract:

Objective

To analyze the influence of acute infection before onset on the levels of immunoglobulins (Igs) and complements (Cs) in serum and renal tissue of adult patients with IgA nephropathy, to provide evidence for the role of infection factors in the occurrence and progression of IgA nephropathy.

Methods

Sixty adult IgA nephropathy patients with acute infection before onset from October 2014 to February 2018 at the Department of Rheumatic Nephropathy of Haikou People's Hospital were selected as a study group, and 60 adult IgA nephropathy patients without acute infection before onset were selected as a control group. The general data, the levels of serum Igs and Cs, and the deposition intensity of Igs and Cs in renal tissue were compared between the two groups.

Results

In the study group, 43 cases (71.67%) had acute upper respiratory tract infection before onset, 11 (18.33%) had acute pulmonary infection before onset, and 6 (10%) had acute digestive tract infection before onset. The 24-hour urinary protein quantity, the levels of serum IgA and IgG of the patients in the study group were (2.82±1.33) g/d, (2.87±1.06) g/L, and (8.14±3.04) g/L, respectively, which were higher than those of the control group (P<0.05). The deposition intensity of IgA, IgG, C3, C4, and C1q in the renal tissue of the study group were significantly higher than those of the control group (P<0.05).

Conclusion

The proteinuria symptoms of IgA nephropathy patients with a history of acute infection before onset are more serious, the levels of serum Ig and the deposition intensity of Igs and Cs in renal tissue are higher, and the prognosis may be worse. Clinicians should give full attention and timely and effective intervention to these patients.
