In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.展开更多

Methods: In this double-blind randomized controlled study, patients aged 65 to 80 who were undergoing spinal fusion surgery for disc herniation were administered flurbiprofen 100 mg (P group, flurbiprofen group), prednisolone 0.6 mg/kg (D group, prednisolone group), prednisolone 0.6 mg/kg plus flurbiprofen 100 mg (P + D group, flurbiprofen + prednisolone group) or normal saline (S group, saline group) 15 minutes before the induction of anesthesia. Plasma samples were collected before surgery (T0) and on day 1 (T1), day 2 (T2) and day 3 (T3) following surgery. At the same time, systemic inflammatory response syndrome (SIRS) was assessed by SIRS criteria. The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) for collected samples were measured. Results: Other groups had significantly lower levels of IL-6, CRP and occurrence of SIRS than S group (p < 0.05). Compared to groups P and D, the levels of IL-6 and CRP in P + D group were significantly lower on T1 (p < 0.05). Peak levels of IL-6 in all groups were presented on T1 (p 0.05). The levels of CRP within three days were significantly different but did not show peak levels (p > 0.05). Conclusion: Compared to prednisolone or flurbiprofen, combining flurbiprofen with prednisolone in elderly surgery patients led to an increased suppression of IL-6.展开更多

Tumor necrosis factor-Alpha (TNF-α) and Interleukin 8 (IL-8) are involved in the pathogenesis of pulmonary TB (PTB). However, the contribution of polymorphisms of these cytokines to PTB susceptibility needed more investigation across geographic regions and ethnic groups. Purpose: The aim of this study was to investigate the association of the TNF-α-308 G/A and IL-8-251T/A polymorphisms with PTB risk in the Congolese population. Methods: This case-control study included 150 PTB patients and 160 control subjects. Blood samples were collected from all participants and were used for the TNF-α-308 G/A and IL-8-251T/A genotyping by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Odds ratios (OR) were calculated to estimate the potential polymorphism associations. A P level of Results: A significant difference was found between PTB patients and controls regarding the TNF-α-308AA genotype (P = 0.035) distribution. Moreover, this genotype was associated with risk to TB (OR = 7.19, 95% CI = 0.85 - 60.65, P = 0.035). The A allele was significantly more frequent in PTB patients than in controls, and was associated with risk to PTB (OR = 1.68, 95% CI = 1.05 - 2.68, P = 0.014). Regarding the IL-8-251T/A gene, TA and AA genotypes were significantly more frequent in PTB patients compared to controls, and were associated with increased risk to PTB (OR = 2.64, 95% CI = 0.97 - 7.18, P = 0.031 and OR = 3.0, 95% CI = 1.13 - 7.98, P = 0.014, respectively). However, the IL-8-251 A allele was not associated to PTB susceptibility (OR = 0.27, 95% CI = 0.15 - 0.44). Conclusion: TNF-α-308G/A and IL-8-251T/A polymorphisms may be associated to PTB susceptibility in the Congolese population, and the AA genotype of both cytokines could be a risk factor.展开更多
