RESUMEN
De novo glomerular injuries or relapse of nephropathy following COVID-19 vaccine has been reported. Here we present the first case of successful treatment of new-onset diabetes mellitus and biopsy-proven IgA nephropathy after COVID-19 vaccination. A 56-year-old man with no known medical history of renal dysfunction or diabetes mellitus developed both within 3 months after receiving a third dose of inactivated COVID-19 vaccine (Vero cells). His symptoms were characterized by brown urine, severe dry mouth, and excessive thirst. Randomly acquired blood glucose levels exceeded 33.3 mmol/L. A kidney biopsy showed IgA nephropathy. He was started on insulin for glycemic control. After glucocorticoid and cyclophosphamide treatment, oral tablets of repaglinide, combined with acarbose, controlled blood glucose and stabilized kidney function. This case is unique because the kidneys and pancreas were simultaneously affected by the vaccine. Successful treatment of the disease proved that cyclophosphamide combined with glucocorticoids were effective and that blood glucose was successfully controlled. This treatment option could be useful in similar cases in the future.
RESUMEN
To observe of alloantibodies of patients with autoimmune hemolytic anemia (AIHA), the alloantibodies masked by autoiantibody were detected by using chloroquine elution test, and the specificity of autoantibody was identified by ether elution test. The results showed that 19 cases out of 38 patients with AIHA were positive detected by indirect antiglobulin test and in 7 cases of them alloantibodies in sera cases were found (1 case of anti-D, 4 cases of anti-E and 2 cases of anti-CE), in 5 cases of them alloantibody were detected carried blood group specificity (3 cases of anti-E, anti-C and anti-c 1 case respectively). In conclusion, detections of alloantibodies by chloroquine elution test and ether elution test were very important for transfusion safety in therapy of patients with AIHA.
