Summary: This study examines the role of alterations in the immune-inflammation system in affective disorders, specifically major depressive disorder (MDD) and bipolar disorder (BD). The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and monocyte/lymphocyte ratio (MLR) are investigated as inflammation markers. The findings reveal elevated NLR and MLR in first-episode and recurrent MDD patients, as well as higher NLR and MLR and lower PLR in BD patients. Moreover, BD manic episode patients have significantly higher NLR and MLR compared to BD depressive episode patients or MDD patients. Overall, this study highlights the importance of systemic inflammation in the pathophysiology of MDD and BD, particularly during manic BD episodes.

Summary: This meta-analysis supports the association between depression and inflammation, with NLR being a potential indicator of depression. However, no significant differences were found in PLR and MLR values between depressed subjects and controls. Further large-scale studies are needed to evaluate the role of PLR and MLR in depression.

Summary: Major depressive disorder (MDD) and bipolar disorders (BDs) are the most severe types of mood disorders (MDs) and are highly disabling worldwide. Inflammatory neuroinflammation may play a role in the pathophysiology of MDs, and there is increasing evidence of its relationship with neurotransmitters, the HPA axis, and neurotrophic factors. Evaluating ratios of neutrophil/lymphocyte, platelet/lymphocyte, and monocyte/lymphocyte in peripheral blood provides a simple method for assessing inflammatory status. This review aims to explore the possible relationships between these ratios and MDs and their potential use in clinical research. The majority of included studies reported higher values of these ratios, particularly in patients with BD during a manic episode, suggesting that they may serve as both state and trait markers. Furthermore, increased NLR and PLR levels appear to predict post-stroke depression. These findings highlight the need for further research and suggest that NLR, PLR, and MLR may be promising tools for evaluating the inflammatory system and understanding the etiology and course of MDs.

Summary: This study analyzed data from 991 ovarian cancer patients and found that the lymphocyte to monocyte ratio (LMR) and platelet to neutrophil ratio (PNR) were independent prognostic indicators of ovarian cancer. In contrast, the platelet to lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) had limited prognostic value. In conclusion, LMR and PNR are superior prognostic indicators in ovarian cancer.

Summary: This study found that inflammatory markers in blood, particularly PLR, were significantly higher in (hypo)manic patients compared to depressed patients. PLR may serve as an independent predictor of (hypo)mania, suggesting that inflammatory markers could explain the onset and recurrence of mood episodes in BD patients. Further research is needed to clarify the role of inflammatory ratios as peripheral biomarkers of BD mood episodes.

Summary: Sex-dependent differences exist in the contribution of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and mean platelet volume-to-platelet ratio (MPR) to COVID-19 severity and mortality. The mortality rate of COVID-19 is higher among men, and men have higher levels of NLR, MLR, and MPR compared to women. NLR, MLR, and PLR have better sensitivity for predicting pneumonia severity in men, while their specificity is enhanced in women.

Summary: This study aimed to explore the possibility of using neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) to predict the prognosis of viral encephalitis (VE). The results showed that elevated NLR and MLR were associated with poor prognosis in VE patients and identified as independent risk factors. NLR > 4.32 and MLR > 0.44 were suggested as cutoff thresholds for predicting poor prognosis in VE.

Summary: This study aimed to investigate the association and potential non-linear relationship between neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and monocyte to lymphocyte ratio (MLR) with depression. Based on a cross-sectional study of US adults, it was found that only PLR was significantly associated with depression. Furthermore, the relationships between NLR, PLR, and MLR with depression were found to be non-linear.

Summary: Despite a multimodal radical treatment, mortality of advanced epithelial ovarian cancer (AEOC) remains high. This study investigates the prognostic value of neutrophil, monocyte, and platelet to lymphocyte ratios (NLR, MLR, PLR) in newly diagnosed AEOC patients undergoing primary debulking surgery (PDS) or interval debulking surgery (IDS). The results suggest that NLR and PLR may have prognostic value in PDS, but not in IDS.

Summary: This study found that the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are significantly higher in patients with depression. However, the monocyte-to-lymphocyte ratio (MLR) is slightly higher but not significantly different. Sensitivity and subgroup analysis revealed differences in inflammatory ratios in different regions and in patients with post-stroke depression (PSD).

Summary: This meta-analysis found that pretreatment neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) may serve as biomarkers for predicting poor prognosis in patients with endometrial cancer, while monocyte-lymphocyte ratio (MLR) is not associated with prognosis.

Summary: The study found that NLR and PLR were associated with disease activity in RA patients based on the DAS28 scoring system, but LMR showed no significant difference. However, these indicators performed poorly in differentiating active RA patients from inactive RA patients compared to traditional inflammatory markers with higher sensitivity and specificity. Combining NLR or PLR did not significantly improve the diagnostic value of ESR and CRP.

Summary: This study found that the neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-monocyte ratio (NMR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) can be important indicators for evaluating the treatment of psoriasis patients. The SII showed strong positive correlations with the NLR, NMR, and PLR. TNF-α blockers such as Adalimumab, etanercept, and infliximab were found to be especially effective on PLR, NLR, and NMR.
