IL6 and lymphopenia: In contrast, inflammatory markers were elevated (peak CRP (C-reactive protein) 16.6 mg/dL), and cytokine profiling revealed significant elevations in IL-6 (interleukin-6) (107 pg/mL), sIL-2R (soluble interleukin-2 receptor), TNF-α (tumor necrosis factor-alpha), and IL-10, accompanied by profound lymphopenia.
