Systemic isotretinoin has an impact on hemoglobin, ferritin, urea, ceruloplasmin, albumin, uric acid levels, and neutrophil to lymphocyte ratio in acne patients

Meta-analysis of postoperative incision infection risk factors in colorectal cancer surgery

Objective

To evaluate the risk factors for postoperative incision infection in colorectal cancer, this meta-analysis aimed to identify key variables impacting infection incidence following colorectal cancer surgery.

Methods

Utilizing a meta-analytical approach, studies published from January 2015 to December 2022 were systematically collected and analyzed through the assessment of factors like body mass index, diabetes, albumin levels, malnutrition, and surgical duration.

Results

The meta-analysis of eleven high-quality studies revealed that elevated BMI, diabetes, low albumin levels, malnutrition, and extended surgical duration were associated with increased infection risk, while laparoscopic procedures showed potential for risk reduction.

Conclusions

This study underscores the significance of preoperative risk assessment and management in mitigating postoperative incision infections in colorectal cancer patients. The findings present actionable insights for clinicians to enhance patient prognoses and overall quality of life.

Serum Ceruloplasmin-to-Albumin Ratio as a Biochemical Marker in Pulmonary Tuberculosis Before and After Treatment

BACKGROUND

The study compares the serum ceruloplasmin-to-albumin ratio of tuberculosis (TB) patients before and after anti-tuberculosis treatment (ATT) to assess its diagnostic and prognostic value. Despite the pandemic's impact on TB notifications, global TB cases rose by 16% in 2022.

METHODS

The study was conducted at Meenakshi Medical College Hospital and Research Institute, Kanchipuram, from November 2022 to November 2023, with participants aged 15 and above diagnosed with pulmonary TB. The analysis of clinical, radiographic, microbiological, and biochemical data revealed a gender distribution of 58% male and 42% female individuals, with an average age of 49. Significant reductions in ceruloplasmin levels and increases in albumin levels were found following therapy, as well as a decrease in the ceruloplasmin-to-albumin ratio, showing that ceruloplasmin may serve as a severity measure and treatment indicator.

RESULTS

Male patients accounted for 58% of the study population, while females accounted for 42%. Patients aged 36-45 made up the largest group (26%). Following treatment, serum ceruloplasmin levels decreased significantly (from 66.28 mg/dL to 35.56 mg/dL), but albumin levels increased (from 2.96 g/dL to 4.19 g/dL). The ceruloplasmin-to-albumin ratio dropped from 0.022 to 0.008, showing treatment efficacy.

CONCLUSIONS

The study highlights the potential of serum biomarkers for diagnosing and monitoring TB. The serum ceruloplasmin-to-albumin ratio is a promising biochemical diagnostic. Further research is needed to validate these findings and investigate their clinical significance in TB management.

Effect of isotretinoin treatment on inflammatory and hematological parameters in patients with acne vulgaris

PURPOSE

Although the inflammatory and anti-inflammatory effects of isotretinoin (ISO) treatment in patients with acne vulgaris have been discussed in the literature in recent years, no sensitive and specific marker has been found in studies so far. Neutrophil/HDL (high-density lipoprotein) (NHR), lymphocyte/HD L(LHR), platelet/HDL (PHR), and lymphocyte/monocyte (LMR) are new biomarkers related to inflammation. Triglyceride/HDL (TG/HDL), LDL/HDL, and total cholesterol/HDL have been shown to be cardiometabolic risk factors predicting both cardiovascular disease risk and metabolic risk, rather than just a simple dyslipidemia scale. To our knowledge, the relationship between these parameters and ISO treatment has never been studied before. We aimed to evaluate the immuno-inflammatory response of ISO treatment in patients with acne vulgaris with NHR, LHR, PHR, LMR, TG/HDL, LDL/HDL, and total cholesterol/HDL parameters.

MATERIALS AND METHODS

In this study, 153 patients who received oral ISO treatment for at least 3 months with a diagnosis of moderate-severe acne vulgaris were evaluated retrospectively. Patients were given oral isotretinoin at a dose of 0.5-1 mg/kg. Pre and post-treatment leukocyte (WBC), neutrophil (NE), lymphocyte (LY), platelet (PLT), red cell distribution width (RDW), plateletcrit (PCT), neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), mean platelet volume (MPV), monocyte/lymphocyte (MLR), LMR, total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, MHR, NHR, LHR, PHR, TG/HDL, total cholesterol/HDL, LDL/HDL parameters were evaluated.

RESULTS

It was found that post-treatment WBC and MPV values increased statistically significantly; NLR, neutrophil, and PCT values, on the other hand, decreased significantly (p < 0.05). No statistically significant change was detected in PLR, MLR, LMR, MHR, NHR, LHR, PHR, lymphocyte, monocyte, platelet, and RDW parameters (p > 0.05). It was determined that post-treatment total cholesterol, triglyceride, VLDL, and LDL levels increased statistically significantly; however, the HDL level decreased significantly (p < 0.05). Levels of total cholesterol/HDL, TG/HDL, and LDL/HDL were also found to increase statistically significantly (p < 0.05).

CONCLUSION

Our study suggests that the MPV and NLR ratio as biomarkers can be used as indicators of atherosclerosis-related inflammation due to ISO treatment, but the MHR, NHR, LHR, PHR, MLR, LMR ratios cannot be used. Moreover, we believe that the ratios of TG/HDL, LDL/HDL, and total cholesterol/HDL offer a new contribution as indicators of cardiovascular risk and systemic inflammation related to ISO treatment.

Physiological and Psychological Effects of Isotretinoin in the Treatment of Patients with Acne: A Narrative Review

Isotretinoin (ISO) is a powerful vitamin A derivative that offers the potential for treatment of permanent remission of acne; however, its potential side effects on both physiological and psychological aspects limit its application. This article reviews the side effects of ISO from physiological and psychological aspects in detail, to better screen the suitable population of ISO and improve the efficiency of clinical treatment. Our findings indicate that ISO may cause teratogenicity, skin reactions, ocular reactions, changes in blood indicators, and occasional acne fulminans. To optimize clinical treatment, more attention should be paid to identifying the specific conditions under which these reactions occur, how severe they are, and how they subside to alleviate patient concerns. Regarding the controversial issue of psychological side effects caused by ISO, researchers should shift their focus to the psychological problems that acne itself may cause.

Markers of Oxidative Stress in Patients with Acne: A Literature Review

Acne vulgaris is a chronic inflammatory skin disease of the pilosebaceous unit. Its pathogenesis is multifactorial and involves the overlap between four main processes: alteration of the keratinization, increased sebum production, colonization with Cutibacterium acnes, and inflammation. The role of oxidative stress (OS) has been intensively studied in inflammatory skin conditions such as psoriasis, vitiligo, or atopic dermatitis. However, the involvement of OS in the pathogenesis of acne is less known. The evidence accumulated over the last decade suggests that in the case of acne patients, there is an imbalance between oxidants and antioxidants. In this review, we analyzed studies that evaluated markers of OS in patients with acne, published in the last ten years, with the aim of providing new insights into the pathogenesis of acne.

Topical Isotretinoin (TMB-001) Treatment for 12 Weeks Did Not Result in Clinically Relevant Laboratory Abnormalities in Participants with Congenital Ichthyosis in the Phase 2b CONTROL Study

INTRODUCTION

Treatment with oral retinoids can be effective in patients with congenital ichthyosis (CI) but may be associated with clinically significant laboratory changes. In this Phase 2b CONTROL study analysis, we characterize the effects of TMB-001, a novel topical isotretinoin formulation, on laboratory values in participants with X-linked recessive (XLRI) and autosomal recessive lamellar (ARCI-LI) ichthyosis at 12 weeks.

METHODS

A randomized, double-blind, vehicle-controlled, Phase 2b study was conducted with participants ≥ 9 years of age with confirmed XLRI and ARCI-LI. Participants were randomized 1:1:1 and stratified by CI subtype to receive TMB-001 0.05%:TMB-001 0.1%:vehicle twice daily for 12 weeks. Laboratory analyses were performed at screening and Week 12.

RESULTS

Among 33 enrolled participants (TMB-001 0.05% n = 11, TMB-001 0.1% n = 10, and vehicle n = 12), 52% had ARCI-LI and 48% had XLRI. At 12 weeks, there were single reports of anemia, neutropenia, leukopenia, lymphocytosis, and leukocytosis after vehicle treatment; neutropenia was reported in one participant receiving TMB-001 0.1%. There were single reports of abnormal biochemistry values-liver enzymes, creatinine, urea nitrogen, hyperkalemia, and hyperproteinemia-across treatment cohorts. Non-fasting hyperglycemia was observed in three participants receiving TMB-001 0.1% and one participant receiving vehicle. Urinalysis abnormalities reported in > 1 participant included urobilinogen (TMB-001 0.1% n = 2, vehicle n = 2), protein (TMB-001 0.1% n = 3, vehicle n = 2), and leukocyte esterase (TMB-001 0.1% n = 2). Laboratory parameter changes were asymptomatic and did not require study discontinuation or drug withdrawal.

CONCLUSION

There were no clinically significant laboratory changes in participants receiving TMB-001 isotretinoin ointment through 12 weeks of treatment, which differs from reported results for systemic isotretinoin.

High Neutrophil-to-Lymphocyte Ratio Facilitates Cancer Growth-Currently Marketed Drugs Tadalafil, Isotretinoin, Colchicine, and Omega-3 to Reduce It: The TICO Regimen

Simple Summary

Several elements that are composed of, or related to, neutrophils, have been shown to inhibit strong immune responses to cancer and promote cancers’ growth. This paper presents the collected data showing these elements and how their coordinated actions as an ensemble facilitate growth in the common cancers. The paper goes on to present a drug regimen, TICO, designed to reduce the cancer growth enhancing effects of the neutrophil related elements. TICO uses four already marketed, readily available generic drugs, repurposed to inhibit neutrophil centered growth facilitation of cancer.

Abstract

This paper presents remarkably uniform data showing that higher NLR is a robust prognostic indicator of shorter overall survival across the common metastatic cancers. Myeloid derived suppressor cells, the NLRP3 inflammasome, neutrophil extracellular traps, and absolute neutrophil count tend to all be directly related to the NLR. They, individually and as an ensemble, contribute to cancer growth and metastasis. The multidrug regimen presented in this paper, TICO, was designed to decrease the NLR with potential to also reduce the other neutrophil related elements favoring malignant growth. TICO is comprised of already marketed generic drugs: the phosphodiesterase 5 inhibitor tadalafil, used to treat inadequate erections; isotretinoin, the retinoid used for acne treatment; colchicine, a standard gout (podagra) treatment; and the common fish oil supplement omega-3 polyunsaturated fatty acids. These individually impose low side effect burdens. The drugs of TICO are old, cheap, well known, and available worldwide. They all have evidence of lowering the NLR or the growth contributing elements related to the NLR when clinically used in general medicine as reviewed in this paper.
