Sympathetic activation: a potential link between comorbidities and COVID-19. COPD is a complex and heterogeneous disease, frequently associated with several comorbidities [15]. If you remember cellular respiration, you will understand quickly why these molecules (oxygen, carbon dioxide, and water) link the lungs, kidneys, and circulatory system so intimately. 1) [25,26,27,28,29]. The complex interplay between injured organs in patients with multiple organ dysfunction syndrome has been called “the slippery slope of critical illness” [78]. COPD is considered the result of inflammatory processes of the airways and destructive changes of lung parenchyma, which lead to a progressive and irreversible airflow limitation. Epub 2011 May 11. Bioanalysis 6(6):843–857, Jankowski J, Westhof T, Vaziri ND et al (2014) Gases as uremic toxins: is there something in the air? For example: Liver = Anger Spleen = Worry or Overthinking Heart = Joy Kidneys = Fear Lungs = Sadness or Grief. Your lungs, as you probably know, are a pair of highly elastic and spongy organs that sit inside your chest on either side of your heart. Cardiovascular Functional Changes in Chronic Kidney Disease: Integrative Physiology, Pathophysiology and Applications of Cardiopulmonary Exercise Testing. They may also occur together when a patient has certain conditions. Furthermore, at histopathologic level these functional modifications are supposed to correspond to a thickening of basal lamina of the pulmonary capillaries. Scand J Clin Lab Invest 56:393–399, Soriano JB, Visick GT, Muellerova H, Payvandi N, Hansell AL (2005) Patterns of comorbidities in newly diagnosed COPD and asthma in primary care. J Cell Mol Med. The average length is 10 to 14 inches (25 to 35 cm) and the maximum width about 4 to 6 inches (10 to 15 cm). Patients with advanced cystic fibrosis, who often develop respiratory failure and hypercapnia, may have altered electrolyte transport and malnutrition. (2003). But doctors are finding its damage in kidneys, hearts and elsewhere. Each of these neurohormonal pathways may result in a reduction of renal blood flow and GFR, fluid retention (salt and water), and oliguria. A Preliminary study in a sample of patients enrolled in the EXCITE trial. Some cancer treatments can affect the function of major organs like the heart, kidneys, liver and lungs. A second dose of seasonal influenza vaccine showed no benefit to hemodialysis patients [60]. Besides, the lung governs respiration and the kidney receives qi. Some studies have proved that patients with both type 1 and 2 diabetes mellitus show impaired alveolar-capillary diffusion capacity for carbon monoxide (DLCO), as well as reduced lung volumes and flows, if compared to healthy subjects. Epub 2020 Aug 1. Vasculitides and autoimmune disorders are the best-known examples. A significant interaction between kidneys and lungs has been shown in physiological and pathological conditions. Chest 124(2):490–493, Sbardella E, Isidori AM, Arnaldi G et al (2018 Jan) Approach to hyponatremia according to the clinical setting: consensus statement from the Italian Society of Endocrinology (SIE), Italian Society of Nephrology (SIN), and Italian Association of Medical Oncology (AIOM). Kidneys are those parts of the urinary system that take out waste products from the blood. Epub 2017 Apr 11. "Lung, kidney and cardiovascular issues are confirmed as complications of COVID-19". The relationship between Lung and Kidney in TCM theory . Treatment of pneumonia in hemodialysis patients does not differ from the one for the general population, but the death rates are 14–16 times higher [58]. They may also occur together when a patient has certain conditions. This makes them especially prone to illness in individuals wh… Sorino C, Scichilone N, Pedone C, Negri S, Visca D, Spanevello A.

The two organs can both be targets of the same systemic disease (eg., some vasculitides). The relationship between the heart and the liver is signified by circulation of blood and regulation of mental activities. Visconti L, Santoro D, Cernaro V et al (2016) Kidney–lung connections in acute and chronic diseases: current perspectives. Kidney qi must be strong so as to have smooth respiration and a clear airway. When present as a comorbidity, renal failure implies negative prognostic repercussions and affects therapeutic strategies [35].

Carbon dioxide is a slightly acidic compound. Neurohormonal effects of PPV include the production of vasoactive substances, rennin-angiotensin axis activation, increased nonosmotic vasopressin (ADH) secretion, suppression of atrial natriuretic peptide (ANP) release, downstream stimulation of aldosterone production. A quite high percentage of anergy (30–40%) due to a defective cellular immunity has been described in this population, with resulting reduction of hypersensitivity skin reactions and TST sensitivity [61]. Renal compensation usually requires a few days as it is achieved through changes in bicarbonate reabsorption.

Eur Respir Monograph 59:(13–27), Bon JM, Zhang Y, Duncan SR et al (2010) Plasma infl ammatory mediators associated with bone metabolism in COPD. Pneumonia are the second more common cause of severe infections among subjects undergoing hemodialysis [57]. The relationship between the lung and the kidney is signified by respiration and fluid metabolism. J Nephrol 29:881, Solazzo A, Botta C, Nava F et al. Vaccination against Streptococcus pneumonia and seasonal influenza is recommended for these patients. The link between COPD and kidney disease has been investigated previously. Am J Respir Crit Care Med 161:1094–1100, Almagro P, Calbo E, Ochoa de Echagüen A et al (2002) Mortality after hospitalization for COPD. When renal failure occurs in COPD patients, the compensatory role of kidney in respiratory acidosis may be less effective, resulting in a reduced ammoniagenesis and titratable acidity production with consequent limited rise of serum bicarbonate and a more severe acidosis. Pulmonary-renal syndrome can be also induced by microscopic polyangiitis and immune-complex vasculitides like systemic lupus erythematosus, cryoglobulinemic vasculitis, and Schönlein-Henoch Purpura. Nat Rev Nephrol 12(1):48–60, Dushianthan A, Grocott MP, Postle AD, Cusack R (2011) Acute respiratory distress syndrome and acute lung injury. In cases of “pump failure” with hypoventilation, e.g., due to emphysema or neuromuscular diseases, carbon dioxide (CO2) retention is frequently observed. Method Retrospective longitudinal analyses were conducted among subjects who participated in comprehensive health check-ups at least four times during 7 years (between 2006 and 2012). Renal compensation usually requires a few days as it is achieved through changes in bicarbonate reabsorption. Respir Res 14:31, Corsonello A, Aucella F, Pedone C, Antonelli-Incalzi R (2017) Chronic kidney disease: A likely underestimated component of multimorbidity in older patients with chronic obstructive pulmonary disease. Acid–base balance can be influenced by drugs frequently used in patients with chronic renal failure, such as diuretics. Most infections during the first month after kidney transplantation are caused by hospital bacteria. Given names of all the authors have been interchanged with family names. Lungs and kidneys are different organs with their own body localization, structure, and function, but it is a shared concept that they are not completely independent from each other and can suffer damages concurrently in the course of systemic diseases (Table 1) [1].
