Elevated neutrophil lymphocyte ratio in patients with substance use disorders

IntroductionDisturbances in inflammatory processes may play a role in the pathophysiology of psychiatric disorders. The neutrophil lymphocyte ratio (NLR) and C-reactive protein (CRP) are indicators of the systemic inflammatory response.ObjectivesThe current study was prepared based on the assumption that dysregulated immune function and elevated inflammation markers may be seen in substance use disorders.AimsOur aim was to investigate whether NLR and CRP are higher in patients diagnosed with substance use disorders than in healthy subjects.MethodsThe participants in the study included 115 male inpatients diagnosed with alcohol (n = 41), heroin (n = 46), or synthetic cannabinoid (n = 28) dependence according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV-TR), and 32 healthy male volunteers. We used NLR and CRP as measures of systemic inflammation. Blood samples were taken on the next morning of admission for detoxification. Addiction severity was assessed using the Addiction Profile Index (API).ResultsThe difference between the groups with respect to NLR was statistically significant (P = 0.014). Patients diagnosed with alcohol, heroin or synthetic cannabinoid dependence had similar NLR. Patients with alcohol or synthetic cannabinoid dependence had significantly higher NLR than healthy controls (P = 0.001 and P = 0.029, respectively). Patients with heroin dependence trended towards statistically significantly higher NLR compared to healthy controls (P = 0.067). CRP levels did not differ significantly between the patient and control groups. NLR and CRP were not significantly correlated with API scores.ConclusionsOur findings suggest that NLR is elevated in patients with substance use disorders in comparison to healthy controls.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Objective: To examine potential associations between neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, mean platelet volume (MPV), HbA1c and microvascular complications in diabetic patients from a cost-effectiveness perspective. Methods: One hundred patients with type 2 diabetes attending our outpatient unit between May 2018 and October 2018 were included, and 100 healthy individuals served as the control group. A retrospective file search was performed to collect information on hemoglobin, mean platelet volume (MPV), glycosylated haemoglobin (HbA1c), hematocrit (Hct), neutrophil and lymphocyte count, neutrophil/lymphocyte ratio (NLR), platelets (Plt), platelet/lymphocyte ratio (PLR), and microvascular complications (neuropathy, retinopathy, nephropathy). Results: Demographic and laboratory data were retrospectively controlled between diabetes (n=100) and healthy control (n=100) groups. The mean age in diabetic patients and healthy controls was 56.34 and 36.68 years, respectively. The mean NLR in diabetics and healthy controls was 2.48 and 2.11, the difference in NLR being significant (p=0.002). MPV in diabetics and controls was 8.54 and 8.53, respectively, and the difference was not significant (p=0.93). PLR was also similar, i.e. 149.7 and 145.3 in diabetics and healthy controls (p=0.067). With respect to microvascular complications, retinopathy was found to be significantly associated with MPV and NLR (p=0.015, and p=0.051), and nephropathy showed a significant association with NLR (p=0.027) among diabetics. In contrast with the two other microvascular complications, no significant association between neuropathy and NLR could be detected, while PLR and neuropathy was significantly associated (p=0.003). Conclusion: Microvascular complications may be associated with certain hematologic parameters, as suggested by comparisons both between diabetics and healthy individuals and within the group of diabetic individuals. We believe that hematologic parameters such as hematocrit, MPV, NLR, and PLR, which can be obtained through a simple complete blood count, may be utilized as cost-effective predictors of diabetic microvascular complications. Further prospective studies with larger sample size are required to better delineate these associations. doi: https://doi.org/10.12669/pjms.35.6.1150 How to cite this:Onalan E, Gozel N, Donder E.

Competing Interest

Substance Use Disorders (SUD) and Attention Deficit Hyperactive Disorder (ADHD) are frequent conditions in out drug treatment centers. There are evidences about the high prevalence of ADHD in SUD patients (20%) compared with just ADHD in general population (1–7.3%). Both disorders and psychiatric comorbidity are important in the diagnosis proceeding. The objective of this study is search the difference in psychiatric comorbidity conditions between patients with ADHD and Cocaine SUD and ADHD and Cannabis SUD. ADHD was present in 158 patients of a total sample in which 46,8% used cocaine, 17.1% cannabis and 36.1% used both. Mood disorders were 26.8% in cocaine users, 21.7% in cannabis and 18.9% in both. Anxiety disorders were 20.3% in cocaine users, 37.5 in cannabis and 13% in both users. Primary psychotic disorders were 2.9% in cocaine users, none in cannabis and 11,1% in both drug users. Personality disorders by cluster were, Cluster A: 11.3% in cocaine group, 36% in cannabis group and 24.5 in cannabis and cocaine group. Cluster B: 33.8% in cocaine group, 44% in cannabis group and 51.9% in cannabis and cocaine group. Cluster C: 9.9% in cocaine group, 28% in cannabis group and 19.2% in cannabis and cocaine group. There could be common pathways of neuronal damage related to psychiatric comorbidity depending of used drug, the differences in comorbidity found in this study could explain a little part of it. It is important to manage SUD-ADHD and other psychiatric comorbidity in order to improve the outcomes of these patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Coronavirus Infection

BACKGROUND: Despite the continuing global spread of the coronavirus infection COVID-19 caused by the SARS-CoV-2 coronavirus, the mechanisms of the pathogenesis of severe infections remain poorly understood. The role of comorbidity with other seasonal viral infections, including influenza, in the pathogenesis of the severe course of COVID-19 remains unclear. MATERIALS AND METHODS: The present study used sera left over from ongoing laboratory studies of patients with varying degrees of severity of COVID-19. The study was approved by the Local Ethics Committee of the Federal State Budgetary Scientific Institution IEM (protocol 3/20 from 06/05/2020). We studied 28 paired samples obtained upon admission of patients to the hospital and after 57 days of hospital stay. Paired sera of patients with COVID-19 were tested for antibodies to influenza A and B viruses. The presence of IgG antibodies specific to the SARS-CoV-2 spike (S) protein was studied using an enzyme-linked immunosorbent assay (ELISA). The serum concentration of C-reactive protein and the neutrophil-lymphocyte ratio on the day of hospitalization were also assessed. RESULTS: At least a 4-fold increase in serum IgG antibodies to SARS-CoV-2 S protein was found both in patients with PCR-confirmed SARS-CoV-2 infection and without PCR confirmation. It was shown that out of 18 patients with moderate and severe forms of COVID-19 infection, six of them showed at least a 4-fold increase in antibodies to influenza A/H1N1, in one to influenza A/H3N2 and in two cases to the influenza B. Laboratory data in these two groups were characterized by significant increases in serum C-reactive protein and neutrophil-lymphocyte ratio concentrations compared with the moderate COVID-19 group. CONCLUSIONS: Serological diagnostics can additionally detect cases of coronavirus infection when the virus was not detected by PCR. In moderate and severe cases of COVID-19, coinfections with influenza A and B viruses have been identified. The results obtained confirm the need for anti-influenza immunization during the SARS-CoV-2 pandemic. Influenza virus screening can significantly improve patient management because recommended antiviral drugs (neuraminidase inhibitors) are available.

Before And After

This study compared the effectiveness of the neutrophil/lymphocyte ratio (NLR) versus C-reactive protein (CRP) for evaluating the prognosis and degree of inflammation in patients with amputation for a diabetic foot ulcer (DFU). This study enrolled 56 patients with amputations for DFU with gangrene and compared the CRP levels and NLR measured before and after surgery. Overall, 24 patients (42%) died within 2 weeks postoperatively. Mortality increased with a preoperative/postoperative CRP difference ≤1.5 ( P < .001) and age 73 years or older ( P < .001). The postoperative NLR was lower than the preoperative value but was not significant as a prognostic or inflammatory marker ( P = .945). An increasing serum CRP level is a significant predictor of mortality. CRP and old age are reliable prognostic factors in patients with DFU.
