However, most of these studies are case reports, and to day, limited cohort studies have been carried out to elucidate the relationship between AITD and nephropathy. In our study, we retrospectively analyzed 1032 nephropathy individuals with and without AITD, and showed the rate of recurrence of AITD among individuals with nephropathy was 7.94% (82/1032). We also noticed that a relative high proportion of TPO-ab or TG-ab in nephropathy individuals without AITD in our study. Although the reason is unclear, we could still conclude that AITD may be one of the factors that contribute to renal impairment in proteinuria. Previous studies possess indicated that changes in thyroid hormone levels (hyperthyroidism or hypothyroidism) could impair renal function.[19] Nevertheless, in the current study, there was no statistical difference between Feet3, Feet4, and TSH levels, indicating that there may be other mechanisms causing kidney damage in nephropathy with concomitant AITD. We found that serum IgG levels were higher in instances of nephropathy individuals with concomitant AITD than in instances of individuals with nephropathy only. A earlier study reported that approximately 25.5% of patients with HT experienced elevated serum IgG levels.[20] Therefore, it is possible that the presence of AITD could increase the serum levels of IgG in individuals with nephropathy. Moreover, circulating immunocomplexes are common in individuals with AITD, including HT and GD.[21] As expected, we AZ 3146 found that serum TG-Ab, TPO-Ab, and TSHR-Ab were significantly higher in individuals with nephropathy and AITD than in those with nephropathy alone. The results indicated the potential relationship between circulating immunocomplexes and the pathogenesis of AITD-related nephropathy. Although both circulating and renal deposited TG-Ab and TPO-Ab were higher in individuals with nephropathy and AITD than in individuals with nephropathy only, we were unable to determine if their deposition is definitely secondary to circulating complexes or a result of in situ complex formation. A retrospective study by Kocak et al[22] pointed out that the pathological types of HT-related nephropathy are varied with the highest prevalence for MN, followed by FSGS, IgA-N, chronic glomerulonephritis, and MCN. Consistently, our biopsy results also showed that MN (37.80%) and FSGS (28.05%) were the most common renal lesions in instances of nephropathy with AITD. Similarly, Mubarak[23] found that MN and FSGS are the most common causes of nephrotic syndrome in nondiabetic adults. The proportions of the types of nephropathy were different among the individuals with this study. The proportions of MsPGN and MCN were higher in instances of nephropathy but reduced instances of nephropathy with concomitant AITD; the proportion of FSGS was improved in the second option. These findings suggest that different circulating immunocomplexes may cause different types of nephropathy. Further studies, however, are needed to investigate this possible association. MN was the most common type of nephropathy in both organizations in our study. MN is characterized by the deposition.
