Postsplenectomy thrombocytosis with pseudohyperkalaemia

Pseudohyperkalemia associated with essential thrombocytosis; a hint for better clinical practice

A 75-year-old man was admitted with a diagnosis of diabetic ketoacidosis and hyperkalemia. During the treatment, he developed refractory hyperkalemia. Following our review, diagnosis of pseudohyperkalaemia secondary to thrombocytosis was made. We report this case to remind the importance of clinical suspicion of this phenomenon to prevent its serious consequences.

Predictive Factors for Platelet Count Variation After Splenectomy in Non-Traumatic Diseases

BACKGROUND

The spleen plays a central role in a range of diseases. As such, great emphasis has been placed on the procedure of spleen removal, the benefits and the numerous associated complications. Given the immediate risk of the thrombotic complications, the aim of this study was to evaluate clinical and laboratory patient characteristics in non-traumatic diseases of the spleen, and to investigate possible predictive factors for platelet count variation following the procedure.

METHODS

A total of 72 patients who underwent splenectomy were included in this retrospective study. Correlation coefficients as well as multiple linear regressions were used to assess the relationship between post-splenectomy platelet count and various preoperative clinical and laboratory patient characteristics.

RESULTS

Following multiple linear regression analysis, we determined that 54.93% of post-splenectomy platelet count variation was explained by admission platelet count (p = 0.00), lymphocyte count (p = 0.04), WBC count (p = 0.00), LOS (p = 0.00), patient gender (p = 0.00), spleen accessibility on admission (p = 0.02) and PT (p = 0.00).

CONCLUSIONS

Platelet count variation following splenectomy for non-traumatic diseases can be predicted by assessing preoperative patient characteristics. The implications of this study suggest that by means of a prediction model, patient care could benefit from assessing and addressing various preoperative factors that lead to these complications.
