IL10 and pneumonitis: Similarly, a retrospective, observational study examining 87 lung cancer patients with CIP and 87 matched controls demonstrated that elevated levels of inflammatory cytokines IL-6 and IL-10, increased neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio, and elevated lactate dehydrogenase were significantly associated with CIP occurrence, while decreased absolute lymphocyte count and reduced albumin levels also correlated with pneumonitis development (37).
