Obesity and main urologic cancers: Current systematic evidence, novel biological mechanisms, perspectives and challenges. Semin Cancer Biol 2023; 91:70-98. [PMID: 36893965 DOI: 10.1016/j.semcancer.2023.03.002] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/06/2023] [Accepted: 03/06/2023] [Indexed: 03/09/2023]
Abstract
Urologic cancers (UC) account for 13.1% of all new cancer cases and 7.9% of all cancer-related deaths. A growing body of evidence has indicated a potential causal link between obesity and UC. The aim of the present review is to appraise in a critical and integrative manner evidence from meta-analyses and mechanistic studies on the role of obesity in four prevalent UC (kidney-KC, prostate-PC, urinary bladder-UBC, and testicular cancer-TC). Special emphasis is given on Mendelian Randomization Studies (MRS) corroborating a genetic causal association between obesity and UC, as well as on the role of classical and novel adipocytokines. Furthermore, the molecular pathways that link obesity to the development and progression of these cancers are reviewed. Available evidence indicates that obesity confers increased risk for KC, UBC, and advanced PC (20-82%, 10-19%, and 6-14%, respectively), whereas for TC adult height (5-cm increase) may increase the risk by 13%. Obese females tend to be more susceptible to UBC and KC than obese males. MRS have shown that a higher genetic-predicted BMI may be causally linked to KC and UBC but not PC and TC. Biological mechanisms that are involved in the association between excess body weight and UC include the Insulin-like Growth Factor axis, altered availability of sex hormones, chronic inflammation and oxidative stress, abnormal secretion of adipocytokines, ectopic fat deposition, dysbiosis of the gastrointestinal and urinary tract microbiomes and circadian rhythm dysregulation. Anti-hyperglycemic and non-steroidal anti-inflammatory drugs, statins, and adipokine receptor agonists/antagonists show potential as adjuvant cancer therapies. Identifying obesity as a modifiable risk factor for UC may have significant public health implications, allowing clinicians to tailor individualized prevention strategies for patients with excess body weight.

Abstract
Psoriatic patients present an increased risk for developing lymphoma, particularly cutaneous T-cell lymphoma (CTCL). To what degree psoriasis itself through chronic immune stimulation, or the immunosuppressive medications used for its treatment or comorbidities (obesity, diabetes mellitus, etc), or lifestyle (smoking, alcohol, diet, etc) may play a role in the onset of MF is not yet clear. Psoriasis and Mycosis Fungoides (MF), the most common variant of CTCL, represent two distinct entities sharing common pathogenetic mechanisms and a wide spectrum of common clinical features associated with the abnormal activation of T-cells. The aim of this study is to explore the relationship between MF and psoriasis by presenting two cases with clinical and histopathologic features of both psoriasis and MF with a particular emphasis on the time of presentation of both disorders, the use of previous immunosuppressive drugs as well as the therapeutic management of patients. Biopsy of the cutaneous lesions before the introduction of biologics should be incorporated in clinical practice. Biopsy of the cutaneous lesion should also be performed in the case of appearance of psoriasiform lesions during biologic treatment for autoimmune disorders because this may represent an indolent form of MF. Psoriatic patients with poor or no-response to treatment should be examined thoroughly for MF using immunochemistry and, if necessary, molecular biology techniques. In concomitant MF and psoriasis, combination treatment may be beneficial for both entities. Finally, a large multicentric registry of MF patients who were treated for benign dermatoses (i.e. eczema, psoriasis) with classic immunosuppressive drugs and/or biologics is needed to collect data and further clarify the enigmatic relationship between psoriasis, MF and immunosuppressive treatment.

Abstract
PURPOSE OF REVIEW Obesity and psoriasis represent chronic inflammatory states that are interconnected in a vicious cycle, sharing also a degree of synergy. In this review, we aim to decipher the various lines of evidence supporting the bidirectional association between psoriasis and obesity highlighting their pathophysiologic connections as well as we attempt to strategize a therapeutic holistic approach for obese psoriatic patients. RECENT FINDINGS Recent meta-analyses have shown that (1) genetically higher BMI increased the odds of psoriasis occurrence; (2) obesity is associated with higher incidence and prevalence of psoriasis as well as psoriasis severity; (3) obesity is associated with lower efficacy to anti-TNF agents and may predict biologic treatment discontinuation; and (4) weight loss through diet and physical exercise may improve pre-existing psoriasis and prevent from de novo psoriasis. Methotrexate, acitretin, and cyclosporine could worsen hypertension, liver steatosis, and dyslipidemia. Since infliximab and ustekinumab are weight adjusted, they may be ideal drugs to treat obese psoriatic patients. IL-17 inhibitors are very effective independently from body weight; however, they tend to present better clearance rates in normal weight patients. There is a paucity on weight data regarding the efficacious IL-23 inhibitors. Apremilast may induce weight loss as an adverse effect presenting also some beneficial metabolic actions. Finally, simvastatin and some antidiabetic drugs could decrease psoriasis severity. More mechanistic, observational studies and well-conducted RCTs are necessary to decipher the enigmatic link between psoriasis and obesity, and to provide evidence-based specific guidelines for the screening and management of obese psoriatic patients.

Abstract
The link between psoriasis and obstructive sleep apnea (OSA) has not been confirmed. We aimed to investigate the relationship between psoriasis and OSA. We conducted a systematic review and meta-analysis of case-control, cross-sectional, and cohort studies on the association between psoriasis and OSA. We searched MEDLINE and Embase for relevant studies on May 11, 2019. The Newcastle-Ottawa Scale was used to evaluate the risk of bias of included studies. We performed random-effects model meta-analysis to calculate pooled odds ratio (ORs) with 95% confidence intervals (CIs) for case-control and cross-sectional studies as well as pooled incidence rate ratio (IRR) with 95% CIs for cohort studies in association between psoriasis and OSA. A total of 4 case-control or cross-sectional studies and 3 cohort studies with a total of 5,840,495 subjects were included. We identified a significantly increased odds for OSA in psoriasis patients (pooled OR 2.60; 95% CI 1.07-6.32), and significantly increased risk for psoriasis in OSA patients (pooled IRR 2.52; 95% CI 1.89-3.36). In conclusion, our study identified a bidirectional association between psoriasis and OSA. Sleep quality should be inquired in patients with psoriasis. Respirologist consultation or polysomnography may be indicated for those presenting with night snoring, recurrent awaking, and excessive daytime sleepiness.

Patients with psoriatic arthritis have higher levels of FeNO than those with only psoriasis, which may reflect a higher prevalence of a subclinical respiratory involvement. Clin Rheumatol 2020; 39:2981-2988. [PMID: 32240433 DOI: 10.1007/s10067-020-05050-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 03/12/2020] [Accepted: 03/20/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Psoriatic arthritis (PsA) patients are often affected by numerous comorbidities. However, contrasting results have been reported with regard to the respiratory involvement in PsA patients. The aim of this study was to evaluate the presence of subclinical airway inflammation in non-smoking PsA patients compared to patients with only psoriasis using the fraction of exhaled nitric oxide (FeNO) as an indirect marker of airway inflammation. METHODS The study included 164 non-smoking psoriatic patients (Psoriasis Area of Severity Index or PASI score > 10): 82 with and 82 without PsA, who underwent FeNO tests at different flow rates (30, 50, 100, 200 mL/s). PsA patients were evaluated with Disease Activity in PSoriatic Arthritis Score (DAPSA). Both study groups were compared in terms of FeNO values and its association with the PASI score. The correlations between the variables were evaluated by means of Pearson's coefficient. RESULTS Patient with PsA had higher levels of FeNO than those with psoriasis but without arthritis (at 30 mL/s, 71.09 ± 18.40 ppb vs 66.88 ± 19.12 ppb (NS); at 50 mL/s, 36.61 ± 9.30 ppb vs 30.88 ± 9.73 ppb (p < 0.001); at 100 mL/s, 19.09 ± 4.66 ppb vs 16.63 ± 4.90 ppb (p < 0.001); and at 200 mL/s, 10.88 ± 2.53 ppb vs 9.43 ± 2.55 ppb (p < 0.001), respectively). PASI score correlated to FeNO only in psoriatic patients without arthritis. However, CASPAR index correlated with FeNO (FeNO30: r = 0.81, p < 0.001; FeNO50: r = 0.84, p < 0.001; FeNO100: r = 0.71, p < 0.001; FeNO200: r = 0.58, p < 0.001). DAPSA was also correlated with FeNO to all flows (FeNO30: r = 0.43, p < 0.001; FeNO50: r = 0.33, p < 0.001; FeNO100: r = 0.34, p < 0.001; FeNO200: r = 0.25, p < 0.001). CONCLUSIONS PsA patients seem to have more commonly subclinical airway inflammation than those with only psoriasis. Further studies are needed to replicate these findings. Key Points • Fraction of exhaled nitric oxide (FeNO) is a useful device to detect and monitor airway inflammation not only in asthma but also in systemic inflammatory diseases such as psoriatic arthritis and psoriasis. • Clinicians should be aware to check respiratory diseases in patients with psoriatic arthritis.

Psoriasis is associated with risk of obstructive sleep apnea independently from metabolic parameters and other comorbidities: a large hospital-based case-control study. Sleep Breath 2017; 21:949-958. [PMID: 28484896 DOI: 10.1007/s11325-017-1507-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2016] [Revised: 04/03/2017] [Accepted: 04/26/2017] [Indexed: 02/08/2023]
Abstract
PURPOSE Obstructive sleep apnea (OSA) represents a breathing disorder during sleep with significant health consequences. Few studies have examined the prevalence of OSA in psoriatic patients and whether OSA may be associated with psoriasis risk. We aimed to explore: (1) the inverse relationship, that is whether psoriasis might represent an independent predictor of OSA and its severity considering important predisposing factors and (2) the psoriatic phenotype related to severe OSA. METHODS In a large hospital-based case-control study, we examined a total of 253 patients with OSA and a control group of 104 subjects without OSA, who underwent full nocturnal polysomnography and dermatologic examination. RESULTS The prevalence of psoriasis was significantly greater in OSA patients than in controls (p = 0.03). Psoriasis was associated with OSA risk (p = 0.04) but not severity of OSA, sleepiness severity or sleep efficiency, independently from age, gender, anthropometric features, and significant comorbidities. The phenotype of a psoriatic patient suffering from severe OSA is not different from that of a patient with severe OSA and is not associated with psoriasis severity indexes. OSA psoriatic patients were not compliant with CPAP treatment in comparison with OSA patients without psoriasis. CONCLUSION Psoriasis may represent an independent risk factor for OSA above and beyond significant comorbidities, anthropometric and metabolic parameters. Physicians should be aware of the bi-directional association of psoriasis and OSA. Managing psoriasis may be a potential target for preventing OSA as well as the potential cardiovascular mortality related to OSA and psoriasis.

Abstract
Psoriasis is a chronic inflammatory disease associated with several comorbidities. A few decades ago, it was considered an exclusive skin disease but today it is considered a multisystem disease. It is believed that 73% of psoriasis patients have at least one comorbidity. Studies have demonstrated the association of psoriasis with inflammatory bowel disease, uveitis, psychiatric disorders, metabolic syndrome and its components and cardiovascular diseases. The systemic inflammatory state seems to be the common denominator for all these comorbidities. This work aims at presenting a review of the current literature on some new comorbidities that are associated with psoriasis as osteoporosis, obstructive sleep apnea and chronic obstructive pulmonary disease. While there is still controversy, many studies already point to a possible bone involvement in patients with psoriasis, especially in the male group, generally less affected by osteoporosis. Psoriasis and chronic obstructive pulmonary disease present some risk factors in common as obesity, smoking and physical inactivity. Besides, both diseases are associated with the metabolic syndrome. These factors could be potential confounders in the association of the two diseases. Further prospective studies with control of those potential confounders should be developed in an attempt to establish causality. Existing data in the literature suggest that there is an association between obstructive sleep apnea and psoriasis, but studies performed until now have involved few patients and had a short follow-up period. It is, therefore, premature to assert that there is indeed a correlation between these two diseases.

Abstract
Psoriasis is a chronic inflammatory skin disorder which can impair general routine activities and has been closely related to poor quality of life. Pruritus and scratching are frequently observed, occurring mainly during sleep and precipitating nighttime arousals. Indeed, sleep quality has been shown to be negatively affected in psoriatic patients, in a close relationship with stress exposure and immune response. Although psoriasis is known to impair sleep, leading to insomnia, its association with obstructive sleep apnea (OSA) is controversial. Similarly, OSA is considered a multifactorial inflammatory disease, characterized by intermittent hypoxia, sleep fragmentation and autonomic dysfunction, with important outcomes on the cardiovascular and metabolic systems. Importantly, immunological activities and pro-inflammatory cytokines play a prominent role in both OSA and psoriasis. Currently it is not clear whether OSA is a risk factor for psoriasis development or if psoriasis is a possible predictor of OSA. Thus, our main purpose is to provide an overview of this intriguing relationship and show the current link between psoriasis and OSA in a bidirectional relationship.

Abstract
AbstractHigher body mass index and adiposopathy have been associated with increased risk of hematologic malignancies such as leukemia, multiple myeloma, myeloproliferative disorders, Hodgkin’s and non-Hodgkin’s lymphoma, and myelodysplastic syndromes. Adiponectin is a multimeric protein of the white adipose tissue presenting anti-inflammatory, insulin-sensitizing, anti-atherogenic, cardioprotective, and anti-neoplastic properties. Its anti-neoplastic actions are manifested via two mechanisms: (i) direct action on tumor cells by enhancing receptor-mediated signaling pathways and (ii) indirect action by regulating inflammatory responses, influencing cancer angiogenesis, and modulating insulin sensitivity at the target tissue site. In the bone marrow milieu, adiponectin and its main receptors are expressed by the majority of bone marrow stromal cell populations influencing hematopoietic stem cells function. Adiponectin may represent a molecular mediator relating adiposopathy with leukemogenesis and myelomagenesis. Several epidemiological studies conducted to date relate hypoadiponectinemia to the risk of myeloid-derived hematopoietic cancer and multiple myeloma. Adiponectin may be a promising biomarker with potential diagnostic and prognostic utility in determining the likelihood of myeloma and leukemia progression in certain cohorts of monoclonal gammopathy of undetermined significance patients and in myeloid hematologic malignancies, respectively. This review summarizes experimental and epidemiologic data regarding the role of adiponectin in hematologic malignancies in the context of adiposopathy. Enhancement of endogenous adiponectin, adiponectin replacement, or manipulation of adiponectin receptor sensitivity may be an attractive goal for prevention and an effective therapeutic strategy against hematopoietic cancer, specifically in overweight/obese individuals. Further studies are required to elucidate the role of the bone marrow microenvironment adiponectin in complex interactions involved in preleukemic and leukemic states.

Abstract
Background Obstructive sleep apnea (OSA) is associated with systemic inflammation and induces various comorbid medical diseases. To date, no study has explored the relationship between OSA and atopic dermatitis (AD), an inflammatory and autoimmune skin disorder. This study investigated the longitudinal risk for AD in patients with OSA. Methods A random sample of 1,000,000 individuals from Taiwan's National Health Insurance database was collected. From this sample, 1222 patients with newly-diagnosed OSA between 2000 and 2005 were identified and compared with a matched cohort of 18330 patients without OSA. All patients were tracked for 5.5 years from the index date in order to identify which patients subsequently developed AD. Results During the 5.5-year follow-up period, the incidence rates of AD in the OSA cohort and comparison groups were 9.81 and 6.21 per 1000 person-years, respectively. After adjustment for age, gender, diabetes, hypertension, coronary heart disease, obesity, allergy, allergic rhinitis, asthma, monthly income, and geographic location, patients with OSA were 1.5-times more likely to develop AD than patients without OSA (95% CI = 1.15–1.95, p = 0.0025). The hazard risk for AD was greater in male OSA patients and young OSA patients (0–18 and 19–34 years), adjusted HRs being 1.53 (95% CI = 1.14–2.06, p = 0.005), 4.01(95% CI = 1.57–10.26, p = 0.0038) and 1.75(95% CI = 1.00–3.04, p = 0.0483), respectively. The log-rank test indicated that OSA patients <35-years-old had significantly higher cumulative incidence rates of AD than those patient of the same age in the comparison group (p = 0.0001). Conclusion Patients with OSA, especially male patients and younger patients, are at an increased risk for AD later in life.

Abstract
Accumulating evidence supports that psoriasis may be a potential multisystem inflammatory disease associated with a range of co-morbidities showing an overlapping pathology and an important health impact such as metabolic diseases. Psoriasis is associated with an increased risk of obesity, metabolic syndrome (Mets) and diabetes mellitus type 2, following a “dose-response” relationship from mild to severe psoriasis. Conversely, recent evidence from large prospective studies suggests that obesity constitutes a risk factor for psoriasis and psoriatic arthritis. Also, a dyslipidemic profile may precede psoriasis onset. Both obesity, Mets and psoriasis, characterized as chronic inflammatory states, stem from a shared underlying pathophysiology exhibiting common genetic predisposition and risk factors such as high caloric intake, physical inactivity and psychological stress. Excess weight may potentiate the inflammation of psoriasis through the deregulation of adipocytokines while, at the same time, it may help the development of Mets. Interestingly, recent translational data has shown that psoriasis, through increased T-helper inflammatory cytokines in skin and sera, may exert a plethora of effects on insulin regulation and lipid metabolism. Larger population-based prospective cohort and longitudinal studies are needed to unravel the association between psoriasis and metabolic co-morbidities. The recognition of the intricate complex interplay between psoriasis and metabolic co-morbidities may help dermatologists to be aware of associated metabolic co-morbidities in order to screen for metabolic diseases and manage holistically and effectively the psoriatic patient.

Abstract
Psoriasis has been lately seen as a potential systemic inflammatory disease associated with a range of co-morbidities exhibiting an overlapping pathology and presenting a great social health impact such as cardiovascular disease and metabolic diseases, including obesity. Adipose tissue is considered a genuine endocrine organ producing a variety of bioactive adipocytokines, like leptin, adiponectin, resistin and visfatin, participating in physiological and pathological processes, such as energy balance, insulin sensitivity and resistance, immunity, inflammation, hematopoiesis and angiogenesis. Adipocytokines could serve as a missing link in the association between psoriasis, obesity and metabolic co-morbidities. In chronic inflammatory disease states such as psoriasis, adipocytokines may be implicated in psoriasis onset, progression, severity as well as in the pathogenesis of co-morbidities. Measuring serum adipocytokine levels in the future may be useful in predicting psoriasis severity, progression, treatment outcome and risk of any co-morbidities. Interventions to decrease pro-inflammatory adipocytokine levels could offer preventive and therapeutic options for improving psoriasis severity and protecting against its co-morbidities. Candidate strategic interventions incorporate increased physical activity, weight control and pharmacologic approaches such as metformin. However, the mechanisms underlying the actions of adipocytokines in psoriasis as well as their potential diagnostic, prognostic and/or therapeutic utility require further investigation with larger prospective, longitudinal and mechanistic studies.

Abstract
Background This study was performed to evaluate neck circumference (NC) and metabolic syndrome (MS) parameters in severe and non-severe (mild-moderate) obstructive sleep apnea syndrome (OSAS) patients according to apnea-hypopnea index (AHI). Material/Method We enrolled 44 patients diagnosed with OSAS based on overnight polysomnography. The diagnosis of OSAS was based on AHI. Apnea is a pause of airflow for more than 10 seconds. and hypopnea is a decrease of airflow for more than 10 seconds and oxygen desaturation of 4% or greater. AHI score. per hour; below 5 normal. 5–29 mild-moderate. 30 and above were grouped as severe OSAS. Height. weight. neck circumference (NC). waist circumference (WC) and body mass index (BMI) of the patients were measured. MS was diagnosed by the Adult Treatment Panel (ATP) III criteria (≥3 of the following abnormalities): 1) WC ≥94 cm for males, ≥80 cm for females; 2) arterial blood pressure ≥130/85 mmHg; 3) fasting blood glucose ≥100 mg/dl; 4) high density lipoprotein (HDL) cholesterol <40 mg/dl in man, <50 mg/dl in women; 5) triglycerides ≥150 mg/dl. Results Mean BMI and NC were higher in severe OSAS patients compared to non-severe patients (p=0.021. p<0.001). According to ATP III criteria. 64% of severe and 61.1% of non-severe OSAS patients were MS (p=0.847). A logistic regression model displayed an association with NC as a risk factor for severe OSAS (p=0.01). but not with MS. Conclusions In this study. NC in severe OSAS patients was significantly higher than in non-severe OSAS patients. The prevalence of metabolic syndrome was not correlated with OSAS severity. NC is an independent risk factor for severe OSAS.
