A common cold is a viral infection , resistance can be normal people about a week to heal . But for some people it can be complicated by serious heart disease or lung infections. Especially in patients with kidney disease with particular attention to the prevention of colds , because the cold can induce and aggravate kidney disease. The following describes the various types of cold kidney disease hazards:
Cold: risk factors associated with acute nephritis
After acute nephritis may be caused by streptococcal infection or strep infection . Acute post -streptococcal glomerulonephritis occurs in the winter , from 1 to 3 weeks after the onset of respiratory infections often cold, namely on . Such patients are also manifestations of tonsillitis , and strep angina, stimulate the body's immune response in patients , after 1 to 3 weeks after the blood of patients with anti-streptolysin "O" antibody ( anti- O antibodies ) increase , decrease complement there glomerular mesangial cells and basement membrane anti-streptococcal antigen .
After the non- streptococcal glomerulonephritis can be caused by a variety of bacteria and viruses . Which influenza virus can directly cause acute nephritis.
Acute nephritis edema, hematuria and hypertension , may also have proteinuria, severe cases can be complicated by renal insufficiency and hypertensive encephalopathy . So after a cold 1 to 3 weeks as edema and hematuria may want to think had acute nephritis.
Cold: a predisposing factor aggravating chronic nephritis
Chronic nephritis by bacteria, viruses or protozoa infection by immune mechanisms and non- immune mechanisms caused partly by acute nephritis evolved . Most insidious onset of chronic nephritis , longer duration, although the same performance as edema , proteinuria, hematuria , and hypertension , but the disease from mild to severe , the development of fast or slow , and some will quickly develop into renal insufficiency.
Kidney nephron and interstitial by the other components , each kidney there are about one million nephrons , renal unit and the renal corpuscles and tubular components. However, the characteristics of the renal unit is not renewable , one hardening necrosis less one like liver cells regeneration.
If the flu occur in patients with chronic nephritis , upper respiratory tract infection , it will trigger an immune response , inflammatory mediators factor nephron damage . Cold will aggravate the damage once again , repeated colds repeated exacerbations will damage the kidneys . When nephron sclerosis necrosis to a certain number , it will cause renal damage .
Particularly a secondary glomerulonephritis - lupus nephritis, immune response is more intense. If repeated colds and upper respiratory tract infection occurs , it will accelerate the development of lesions of lupus nephritis .
Cold: renal dysfunction in patients with risk factors
When nephritis developed to a certain extent , glomerular filtration function is compromised , usually call it that renal insufficiency. Early renal insufficiency may be no obvious self- feeling. But more than 75 percent of kidney damage , creatinine clearance rate is only 25 % or less , serum creatinine will reach about 400mmol / L.
Such patients if a severe colds , upper respiratory tract infection , accompanied by fever , etc., there may be a variety of temporary factors damage the kidneys , creatinine clearance may suddenly drop 5 to 20% , serum creatinine will reach 600 ~ 800mmol / L or more, and in severe gastrointestinal bleeding , potassium , or heart failure. Although this time there will be reversible increase in serum creatinine after treatment may have decreased to some extent , but these risk factors can damage the body's organs, but also serious life-threatening .
Cold : Kidney transplant patients with severe pulmonary infection to be alert
Kidney transplant patients are aware, not life-threatening kidney rejection , but to life-threatening lung infections . Because of a serious lung infection often showed diffuse infection, there hypoxemia, pulmonary edema , use the ventilator to assist breathing, its development process as SARS SARS- like risk is very high. The main cause is the study of mixed infection cytomegalovirus, bacteria and fungi.
Kidney transplant patients to use immunosuppressant immunity generally relatively low . When colds , its recovery will take longer than normal . When a cold fever (39oC or more ) over three days , we must be careful whether it will be complicated by cytomegalovirus infection . Therefore, the best treatment of severe cold while also preventing cytomegalovirus while taking the medicine .
Cold: unexplained hematuria in patients with favorable opportunity to observe
In the hospital outpatient encounter many patients with hematuria of unknown cause . These patients course of several months to several years, and red blood cells in urine and occult blood + ~ + + + , red blood cell count a few to dozens . After various urinalysis , immunology , ultrasound , X ray, CT and other tests , nephritis , or urinary tract infections, or urinary tract stones, or vascular malformations of unknown cause . Because biopsy examination are traumatic and can not proceed.
As mentioned above, the cold can trigger an immune response , exacerbation of chronic nephritis . If the reason is not clear, hematuria caused by the occult nephritis , then within a few days after a cold than the original which can aggravate the degree of hematuria , urinary polycythemia chance shaped red blood cells appear in urine also increased . Shaped red blood cells in urine is an important basis for the diagnosis of nephritis . .
Therefore, patients with hematuria of unknown cause within a week after a cold should go to the hospital to check urine and urine phase contrast microscope to see whether increased urinary red blood cells , red blood cells shaped whether there is , in order to facilitate the diagnosis of hematuria .
Cold: nephritis patients how to prevent
Nephritis patients with flu prevention and healthy people, mainly to avoid exposure to cold , pay attention to exercise and nutrition, enhance physical fitness, avoid contact with flu patients to keep indoor air fresh and so on.
Because most patients with chronic nephritis and chronic pharyngitis, tonsillitis , flu will increase when this inflammation associated with a variety of bacterial and viral infections, so nephritis patients usually should pay attention to oral hygiene to prevent the onset of chronic pharyngitis and tonsillitis . Honeysuckle can be used to drink tea properly with some oral tablets .
Treatment of nephritis patients colds and generally the same , you can use anti-inflammatory drugs and Radix, cold granules and so on. But most people do not advocate the use of antibiotics, cold , and nephritis patients with pharyngitis and tonsillitis due , so you can use some no damage to the kidneys and chronic pharyngitis effective antibiotics , such as amoxicillin , erythromycin, azithromycin .
Cold: nephritis patients can be prevented with cream party
Winter is a good time tonic that nephritis patients to be able to use herbal paste tonic it? In fact, the so-called " compensation" , in a nutshell is the complement of "virtual " meeting " inadequate" , broadly, is the complement of " body balance ." Nephritis patients have the same immune deficiency, also have different physical conditions , so it is applying a different cream party to "fill ."
Nephritis patients with the main principles of herbal paste is kidney , blood circulation, detoxify and Differential Treatment . Mainly to improve the immune status of the kidney , blood circulation is mainly to reduce the immune response , detoxification primarily to reduce inflammation in chronic pharyngitis and tonsillitis , depending on patient diagnosis and treatment is to regulate the body balance, while according to the patient proteinuria, hematuria and renal function to adjust the medication. Also to be used with caution in promoting immunization and other drugs such as Ginseng and Ganoderma lucidum .
