RESUMO
OBJECTIVE: To investigate the correlation between clinical indexes and pathological classifications in 202 patients with lupus nephritis (LN). METHODS: A total of 202 LN cases were retrospectively analyzed. All these patients met the four diagnostic criteria for systemic lupus erythematosus (SLE) of the American College of Rheumatology revised in 1997. The pathological diagnostic criteria of LN were in accordance with the pathological LN classification revised by the International Society of Nephrology and the Society of Kidney Pathology in 2003. The patients were scored according to the improved SLE Disease Activity Index 2000 (SLEDAI-2K), and their basic data, clinical data, laboratory data, and pathological data were collected. RESULTS: Among the 202 patients, the ratio of male to female was 1:5.73, and type IV was the most common pathological LN classification. There were differences in the urine analysis, hypertension incidence, blood cell analysis, blood lipids, renal function, plasma albumin, immunological indexes, renal pathological score among the different pathological types (P < 0.05). In the early finding of renal function damage of the patients, cystatin C sensitivity was significantly higher than that of serum creatinine and blood urea nitrogen. Multiple linear regression analysis show that there are strong correlations between AI and SLEDAI, 24hU-Pr, serum C3, serum ALB, BUN, creatinine, UA and PLT (P < 0.001); and there are correlations between AI and serum IgM, IgA, C4, TC and LDL-C (P < 0.05). CONCLUSION: There is a clear correlation between pathological classifications and clinical indexes of LN. TRIAL REGISTRATION: Shen-PJ-2018-40, Study on Clinical and Molecular Mechanism of SLE.
RESUMO
OBJECTIVE: To observe the natural process of adenoid growth and degeneration as the age grows, to investigate the related clinical significance and pathologic characteristics of hypertrophied adenoid. METHODS: Totally 2650 (age 2 to 87) cases with nasal obstruction or/and other symptoms were included in the patients group, and 810 (age 3 to 85) subjects without symptoms were included as the control group. Morphological characteristics examined with nasal endoscope. Biopsy was performed for 39 cases. The adenoid was calcified as 4 degrees according to the size. RESULTS: In the patient group, age 2 to 9, degree III and degree II adenoid were 81.1% (198/244) and 18.9% (46/244) respectively. And adenoid of children whose age 2 to 5 was 100.0% in degree III; In above 10 years old group, the adenoid was mostly degree II. In age 60 to 69 group, degree 0 was (66.5%), and in age 81 or above, degree 0 reaches 100%. And 19 years old was the youngest age at which adenoid of degree 0 started to be found and 21 was the oldest age at which there is no adenoid of degree III. In the control group, compared with the patient group, no statistical significant difference found in all other groups except in age 2 to 9 (degree III 57.9%, 22/38, degree II 42.1%, 16/38). Shapes of adenoids at degree II varied while degree I were almost like peeled orange. Pathologically, among children there are abundant of adenoidal lymph tissue, while in adults the lymph tissue getting less as age grows but with evident inflammation reaction. Among patients, the incidence of sinusitis and snoring was higher in degree III group compared with others, 47.4% and 18.7% respectively, and the differences is statistically significant (chi2 = 51.28, P < 0.01; chi2 = 40.26, P < 0.01). CONCLUSIONS: Adenoid volume of children (age < 10) is the biggest, especially of children under 5 years old.
