“Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.

Without this balance, nerves, muscles, and other tissues in your body may not work normally.

Your kidneys also make hormones that help

• control your blood pressure
• make red blood cells NIH external link
• keep your bones strong and healthy”

National Institute of Diabetes and Digestive and Kidney Disease – NIDDK  (Your Kidneys & How They Work – NIDDK)

The kidneys are important organs with many functions in the body, including producing hormones, absorbing minerals, and filtering blood and producing urine. While they are important and kidney failure can be fatal, a human only needs one healthy kidney to survive.

The kidneys are two bean-shaped organs that extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body.

They reside against the back muscles in the upper abdominal cavity. They sit opposite each other on either side of the spine. The right kidney sits a little bit lower than the left to accommodate the liver.

When it comes to components of the urinary system, the kidneys are multi-functional powerhouses of activity, for if the kidneys aren’t working, meaning they don’t filter toxic wastes out of our blood stream (with other functions it does) than the waste products don’t get dumped into the urinary bladder from the renal tubes, called right and left ureters. In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. If the kidneys are not working they are not filtering our blood (same principle as filtering beer to make it to perfection, the kidneys do it for our blood to be able to have the cells do their function to the optimal levels with keeping toxins out of the body in preventing many blood problems with more due to acidosis (toxin build up). In the adult, the ureters are usually 25–30 cm (10–12 in) long and ~3–4 mm in diameter.

The kidneys have multiple functions! Some of the core actions of a healthy kidney or kidneys of a human body include:

• Waste excretion: There are many things your body doesn’t want inside of it. The kidneys filter out toxins, excess salts, and urea (a toxin), a nitrogen-based waste created by cell metabolism.
• * Urea is an organic chemical compound and is essentially the waste produced by the body after metabolizing protein. Naturally the compound urea is produced when the liver breaks down protein or amino acids, and ammonia, the kidneys then transfer the urea from the blood to the urine, when they do filtering of the blood.  Urea is a byproduct of protein metabolism, the ending result. Extra nitrogen is expelled from the body through urea because it is extremely soluble (solid); it is a very efficient process. The average person excretes about 30 grams of urea a day, mostly through urine but a small amount is also secreted in perspiration. Synthetic versions of the chemical compound can be created in liquid or solid form and is often an ingredient found in fertilizers, animal food, and diuretics, just to name a few . Urea is what gives our urine the color yellow.         In the gastrointestinal tract, blood proteins are broken down into ammonia (could be due to high protein eating to drugs with actual conditions); and goes to the liver converting it to Urea. It is then released into the blood stream where the kidney’s take it up and eliminate it. Urea is then eliminated by the kidney’s, but not produced by it.  Urea is synthesized in the liver and transported through the blood to the kidneys for removal.
•  A Healthy Kidney or Kidneys functions in the human body doing:
• Water level balancing: As the kidneys are key in the chemical breakdown of urine, they react to changes in the body’s water level throughout the day. As water intake decreases, the kidneys adjust accordingly and leave water in the body instead of helping excrete it which aides in electrolyte balancing in the blood with keeping the body hydrated properly.
• Blood pressure regulation: The kidneys need constant pressure to filter the blood. When it drops too low, the kidneys increase the pressure. One way is by producing a blood vessel-constricting protein (angiotensin) that also signals the body to retain sodium and water. Both the constriction and retention help restore normal blood pressure.
• Red blood cell regulation: When the kidneys don’t get enough oxygen, they send out a distress call in the form of erythropoietin, a hormone that stimulates the bone marrow to produce more oxygen-carrying red blood cells.
• Acid regulation: As cells metabolize, they produce acids. Foods we eat can either increase the acid in our body or neutralize it. If the body is to function properly, it needs to keep a healthy balance of these chemicals. The kidneys do that, too.Because of all of the vital functions the kidneys perform and the toxins they encounter, the kidneys are susceptible to various problems.

• Acute kidney failure is a condition in which the kidneys suddenly lose their ability to function properly. This can occur for many reasons, including:

• Infection
• Blood-clotting disorders
• Decreased blood flow caused by low blood pressure
• Autoimmune kidney disorders
• Urinary tract infections
• Complications from pregnancy
• Most people are born with two kidneys, but many people can live on just one. Kidney transplant surgeries with live donors are common medical procedures today. *
• Chronic kidney failure – same as acute in that the kidney (s) loses its function. 
• DehydrationDiseases and conditions that commonly cause chronic kidney disease include:
• Type 1 or type 2 diabetes.
• High blood pressure
• Glomerulonephritis (gloe-mer-u-lo-nuh-FRY-tis), an inflammation of the kidney’s filtering units (glomeruli)
• Interstitial nephritis, an inflammation of the kidney’s tubules and surrounding structures
• Polycystic kidney disease
• Prolonged obstruction of the urinary tract, from conditions such as enlarged prostate, kidney stones and some cancers
• Vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux, a condition that causes urine to back up into your kidneys
• Recurrent kidney infection, also called pyelonephritis (pie-uh-lo-nuh-FRY-tis)
• A chronic condition caused the failure to happen called a secondary diagnosis.

“Any type of infection caused by the Neisseria meningitidis bacteria is known as meningococcal disease. The two most common types are meningococcal meningitis and meningococcal septicemia (a blood infection).

Meningococcal disease has become less common in the U.S. than it once was. However, in 2024, there was a resurgence with 503 cases reported. But it can be fatal or cause great harm without prompt treatment. According to the CDC, even with antibiotics, 10%-15% of those infected will die, and about 1 in 5 of those who survive are left with long-term disabilities that include deafness, brain damage, neurological problems, and loss of a limb.”

WEB MD (Meningococcal Meningitis: Symptoms, Causes, Treatments)

Meningitis

Your risk for meningococcal meningitis increases if you are exposed to the bacterium that causes it. Your risk also increases if you’ve had a recent upper respiratory infection. Babies, children, teens, and the elderly are at greatest risk.

Signs & symptoms of meningococcal meningitis may vary from case to case. The more common S/S:

• General poor feeling
• Sudden high fever
• Severe, persistent headache
• Neck stiffness
  
• Nausea or vomiting
• Discomfort in bright lights
• Drowsiness or difficulty awakening
• Joint pain
• Confusion or other mental changes

A reddish or purple skin rash (known as petechiae)!!!!!   This is a very important sign to watch for. If it does not turn white when you press on it with a glove the rash may be a sign of bacteremia, or a bacterial infection in the bloodstream. This is a medical emergency.

• Tense or bulging soft spot (in babies)
• High-pitched or moaning cry (in babies)
• Stiff, jerky movements or floppiness (in babies or toddlers)
• Irritability
• Fast breathing
• Lethargy or excessive sleepiness
• Blotchy skin, turning pale or blue
• Shivering, or cold hands and feet
• Seizure

Meningococcal meningitis can cause death or serious complications, such as brain damage, paralysis, gangrene, or deafness. To prevent these problems, it’s important to act quickly. Do not wait. Seek immediate medical attention. Go to an emergency room or call 911 if:

• You notice symptoms of meningococcal meningitis.
• Symptoms do not improve with treatment.
• You think you have been exposed to meningococcal meningitis.

How its diagnosed:

Tests can confirm a diagnosis of meningococcal meningitis;   Meningococcal disease can be difficult to diagnose because the signs and symptoms are often similar to those of other illnesses. If a doctor suspects meningococcal disease, they will collect samples of blood or cerebrospinal fluid (fluid near the spinal cord). Doctors then send the samples to a laboratory for testing.

Treatments:

The doctor may start antibiotics, such as penicillin or ceftriaxone, by an IV, or intravenous line. You or your child may also need other medication to treat problems related to increased spinal fluid pressure. Doctors sometimes prescribe steroids for antiinflammatory effect or the spinal cord.  Penicillin is the drug of choice for the treatment of meningococcal meningitis and septicemia. Chemoprophylactic antimicrobials most commonly used to eradicate meningococci include rifampin, quinolones (eg, ciprofloxacin), ceftriaxone. Also included in this class are minocycline and spiramycin.

Meningococcal meningitis is a serious disease — even with treatment. That’s why prevention is a far better approach. The meningococcal vaccine can prevent meningitis infection. In the U.S., three types of meningococcal vaccines are used that are:

“Meningococcal disease generally occurs 1–10 days after exposure and presents as meningitis in approximately 50% of cases in the United States. Meningococcal meningitis is characterized by sudden onset of headache, fever, and neck stiffness, sometimes accompanied by nausea, vomiting, photophobia, or altered mental status. Approximately 30% of people with meningococcal disease present with meningococcal sepsis, known as meningococcemia.

Meningococcemia often involves hypotension, acute adrenal hemorrhage, and multiorgan failure. An additional 15% of meningococcal disease cases in the United States, primarily among adults >65 years of age, present as bacteremic pneumonia.

Other presentations (e.g., septic arthritis) also occur. Among infants and children aged <2 years, meningococcal disease can have non-specific symptoms. Neck stiffness, usually seen in people with meningitis, might be absent in this age group.

Meningococcal disease progresses rapidly and has a case-fatality rate of 10–15%, even with antimicrobial drug treatment. Without rapid treatment, fatality rates can be much higher.”

Center for Disease Control and Prevention – CDC (Meningococcal Disease | Yellow Book | CDC)

Meningococcal meningitis is a form of meningitis caused by a specific bacterium known as Neisseria meningitidis. Meningitis is characterized by inflammation of the membranes (meninges) around the brain or spinal cord. This inflammation can begin suddenly (acute) or develop gradually (subacute).

Meningococcal meningitis is a form of meningitis caused by a specific bacterium known as Neisseria meningitidis. Meningitis is characterized by inflammation of the membranes (meninges) around the brain or spinal cord. This inflammation can begin suddenly (acute) or develop gradually (subacute). Symptoms may include fever, headache, and a stiff neck, sometimes with aching muscles. Nausea, vomiting and other symptoms may also occur. Skin rashes occur in about half of all individuals with meningococcal meningitis.

Meningococcal meningitis is still associated with a high mortality rate and persistent neurological defects, particularly among infants and young children. Meningococcal meningitis without antibiotic therapy is uniformly fatal.

Meningococcal meningitis evolves when the bacteria, Neisseria meningitidis (N.meningitidis) progresses from initial adherence to the nasopharyngeal (nose and throat) mucosa to invasion of the deeper mucosal layers (the submucosa). These bacteria rapidly multiply, and can lead to a mild (subclinical) infection. However, in approximately 10-20% of cases, the N.meningitidis enters the bloodstream (meningococcemia). This systemic form of the disease, meningococcemia, usually precedes the development of meningococcal meningitis by 24-48 hours.

4 main causes of acute bacterial meningitis:

• Neisseria meningitidis (meningococcus)
• Streptococcus pneumoniae (pneumococcus)
• Haemophilus influenzae
• Streptococcus agalactiae (group B streptococcus)

The WHO World Health Organization states that these bacteria are responsible for more than half of the deaths from meningitis globally and they cause other severe diseases like sepsis and pneumonia; including other bacteria e.g., Mycobacterium tuberculosis, Salmonella, Listeria, Streptococcus and Staphylococcus, viruses such as enteroviruses and mumps, fungi especially Cryptococcus, and parasites like Amoeba are also important causes of meningitis.

Those at Risk:

Although meningitis affects all ages, young children are most at risk. Newborn babies are at most risk from Group B streptococcus, young children are at higher risk from meningococcus, pneumococcus and Haemophilus influenzae. Adolescents and young adults are at particular risk of meningococcal disease while the elderly are at particular risk of pneumococcal disease.

People all over the world are at risk of meningitis. The highest burden of disease is seen in a region of sub-Saharan Africa, known as the African Meningitis Belt, especially recognised to be at high risk of epidemics of meningococcal but also pneumococcal meningitis.

Higher risk is seen when people are living in close proximity, for example at mass gatherings, in refugee camps, in overcrowded households or in student, military and other occupational settings. Immune deficiencies such as HIV infection or complement deficiency, immunosuppression, and active or passive smoking can also raise the risk of different types of meningitis.

“Multiple sclerosis is a disease that causes breakdown of the protective covering of nerves. Multiple sclerosis can cause numbness, weakness, trouble walking, vision changes and other symptoms. It’s also known as MS.

In MS, the immune system attacks the protective sheath that covers nerve fibers, known as myelin. This interrupts communication between the brain and the rest of the body. Eventually, the disease can cause permanent damage of the nerve fibers.

• Age: MS typically makes its first appearance in people between the ages of 20 and 40. 

• Vitamin D Levels: Low levels of vitamin D and low exposure to sunlight are associated with an increased risk of developing MS. 

• Body Weight: Being overweight is more likely to develop MS and can lead to more severe disease and a faster onset of progression. 

• Smoking: Smoking is linked to more relapses, worse progressive disease, and worse cognitive symptoms in people with MS. 

• Gender: Women are up to three times as likely as men to have relapsing-remitting MS. 

• Family History: Having a parent or sibling with MS increases the risk. 
• Infections: Certain infections, including Epstein-Barr virus, have been linked to MS.“

MAYO CLINIC (Multiple sclerosis – Symptoms and causes – Mayo Clinic)

Treatment for Multiple Sclerosis:

Today multiple sclerosis (MS) is not a curable disease. Effective strategies can help modify or slow the disease course, treat relapses (also called attacks or exacerbations), manage symptoms, improve function and safety, and address emotional health.

The model of comprehensive MS care involves the expertise of many different healthcare professionals — each contributing in a unique way to the management of the disease and the symptoms it can cause. Sometimes this team works within a single center, offering “one-stop shopping” for people with MS. More often, people are referred by their MS physician to other specialists in the community.

In either case, the goal is comprehensive=coordinated care to manage the disease and promote comfort, function, independence, health and wellness to its OPTIMAL LEVEL.

There are several types of MS:

For an acute exacerbation of multiple sclerosis that can result in neurologic symptoms and increased disability or impairments in vision, strength or coordination, the preferred initial treatment is usually a type of steroid called a glucocorticoid. Patients who do not have a good response to steroidal therapy are often treated with plasma exchange. Plasma exchange is an extreme therapy that removes antibodies to myelin from the blood.

Some patients have disease that will have an acute exacerbation followed by a prolonged quiet period, which can last years or decades. This form of disease is referred to as relapsed remitting MS, or RRMS. Patients with relapsing MS=RRMS are often treated with immune-modulating drugs such as interferon or glatiramer acetate. Glatiramer is an exciting drug. It is a series of small proteins that are similar to myelin protein. It is thought to prompt the immune system to avoid attacking myelin.

Others have a disease that gets progressively worse over time.

There are two types of progressive disease:

1 In primary progressive MS, or PPMS, symptoms steadily worsen over time from the very beginning.

Progressive MS also referred to as disease-modifying therapies (DMTs).

Presently, these include 15 drug therapies to slow MS activity and progression, each of which is approved by the United States Food and Drug Administration (FDA) for relapsing forms of MS (and some are also approved for clinically isolated syndrome, prior to the diagnosis of MS). One of the medications, Ocrevus™ (ocrelizumab) is also approved for primary-progressive MS. In nearly all instances, these drugs are prescribed individually, so a patient only takes one DMT during any time period. Of these 15 approved drugs, eight are given at home via injection; four are given by a medical professional via intravenous (IV) infusion; and three are taken orally.

In brief, no clinical trial has shown convincing evidence of benefit in the treatment of primary progressive MS. All suggested treatments for PPMS are empiric. Several drugs that are more commonly used in the treatment of malignancy, cladribine and mitozantrone, appear to have some activity.

2 Secondary progressive MS, known as SPMS, begins as relapsed remitting disease and becomes progressive over time.

Available treatments of primary and secondary progressive MS are of limited efficacy and have significant side effects. An additional fact to consider is that most trials have not lasted longer than two or three years and give only hints about long-term results of treatment.

In brief, no clinical trial has shown convincing evidence of benefit in the treatment of primary progressive MS. All suggested treatments for PPMS are empiric. Several drugs that are more commonly used in the treatment of malignancy, cladribine and mitozantrone, appear to have some activity.

In contrast, there is definite modest benefit in some treatments for secondary progressive MS. These treatments include various regimens of steroid therapy (the anti-inflammatory effect) and the use of some drugs that modulate the immune system. Many of these drugs are more commonly used in treatment of cancer and rheumatoid arthritis such as cyclophosphamide, methotrexate and interferon.

MS should be treated by a neurologist who majors in MS with experience in managing it for years.  The doctor with knowledge is so important regarding the specific disease.  Do your research on experts treating this from NY to CA.

Remember the MS treatment is in parts to make up a whole plan:

1 Modifying the disease:

More than a dozen disease-modifying medications have been approved by the U.S. Food and Drug Administration (FDA) to treat relapsing forms of MS. These medications reduce the frequency and severity of relapses (also called attacks or exacerbations),  reduce the accumulation of lesions in the brain and spinal cord as seen on magnetic resonance imaging (MRI) and may slow the accumulation of disability for many people with MS. No medications have yet been approved to treat primary-progressive MS.

2 Treating the Exacerbations:

An exacerbation of MS is caused by inflammation in the central nervous system (CNS) that causes damage to the myelin and slows or blocks the transmission of nerve impulses. To be a true exacerbation, the attack must last at least 24 hours and be separated from a previous exacerbation by at least 30 days. However, most exacerbations last from a few days to several weeks or even months. Exacerbations can be mild or severe enough to interfere with a person’s ability to function at home and at work. Severe exacerbations are most commonly treated with high-dose corticosteroids to reduce the inflammation.

 3 Managing symptoms

In MS, damage to the myelin in the CNS and to the nerve fibers themselves interferes with the transmission of nerve signals between the brain and spinal cord and other parts of the body. This disruption of nerve signals produces the symptoms of MS, which vary depending on where the damage has occurred. MS symptoms can be effectively managed with a comprehensive treatment approach that includes medication(s) and rehabilitation strategies.

4 Promoting function through rehabilitation

Rehabilitation programs focus on function — they are designed to help you improve or maintain your ability to perform effectively and safely at home and at work. Rehabilitation professionals focus on overall fitness and energy management, while addressing problems with accessibility and mobility, speech and swallowing, and memory and other cognitive functions. Rehabilitation is an important component of comprehensive, quality healthcare for people with MS at all stages of the disease. Rehabilitation programs include cognitive and vocational rehabilitation, physical and occupational therapy, therapy for speech and swallowing problems, and more. 

5 Providing emotional support

Comprehensive care includes attention to emotional health as well as physical health. Mental health professionals provide support and education, as well as diagnose and treat the depression, anxiety and other mood changes that are so common in MS. Neuropsychologists assess and treat cognitive problems.

MS is only part of overall health for a pt diagnosed with this disease!  Comprehensive MS care is only a part — but not all — of a person’s overall health management strategies.

Like the general population, people with MS are subject to medical problems that have nothing to do with their MS — which means that regular visits with a primary care physician and age-appropriate screening tests are just as important for them as they are for everyone else. And the same goes for family members — your health and well-being are important too.

“Women are more likely to get MS than men. People of all races and ethnicities can get MS, but it’s most common in White people.

Having a parent or sibling with MS increases the chances of a person getting MS, although MS itself isn’t an inherited disorder. Research suggests hundreds of genes and gene variants (also called mutations) combine to create vulnerability to MS.

Some of these genes have been identified, and most are related to functions of the immune system. Some of the known genes are like those that have been identified in people with other autoimmune diseases, such as inflammatory bowel disease, celiac disease, type 1 diabetes, rheumatoid arthritis, or lupus.

Several viruses have been found in people with MS, but the virus most consistently linked to the development of MS is the Epstein-Barr virus (EBV) which causes infectious mononucleosis.”

NIH – National Institute for Neurological Disorders and Stroke (Multiple Sclerosis (MS) | National Institute of Neurological Disorders and Stroke)

Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body.

It can be a challenge for doctors to diagnose multiple sclerosis (MS). There’s no one test that can definitely show if someone has it. And there are many conditions with symptoms that can seem like MS.

But a neurologist who specializes in treating the disease should be able to look into how you’re feeling and help you figure out if your symptoms mean you have MS or another problem.

SYMPTOMS OF MULTIPLE SCLEROSIS:

Multiple Sclerosis symptoms vary from person to person but there are common symptoms with MS. Those could be the following:

*Fatigue-Occurs in about 80% of people, can significantly interfere with ability to function at home and work, and may be the most prominent symptom in a person who otherwise has minimal activity limitations.

*Difficulties with your walking gait-Related to several factors including weakness, spasticity, loss of balance, sensory deficit and fatigue, and can be helped by physical therapy, assistive therapy and medications.

*Numbness or Tingling-Numbness of the face, body, or extremities (arms and legs) is often the first symptom experienced by those eventually diagnosed as having MS.

*Spasticity-Refers to feelings of stiffness and a wide range of involuntary muscle spasms; can occur in any limb, but it is much more common in the legs.

*Weakness-Weakness in MS, which results from deconditioning of unused muscles or damage to nerves that stimulate muscles, can be managed with rehabilitation strategies.

*Visual Problems-The first symptom of MS for many people. Onset of blurred vision, poor contrast or color vision, and pain on eye movement can be frightening — and should be evaluated promptly.

*Dizziness or Vertigo-People with MS may feel off balance or lightheaded, and for some even much less often have the sensation that they or their surroundings are spinning (vertigo).

*Bladder Problems-Bladder dysfunction, which occurs in at least 80% of people with MS, usually can be managed quite successfully through dietary and fluid management, medications, and catheterization.

*Sexual Problems-Very common in the general population including people with MS. Sexual responses can be affected by damage in the central nervous system, as well by symptoms such as fatigue and spasticity, and by psychological factors.

*Bowel Function-Constipation is a particular concern among people with MS, as is loss of control of the bowels. Bowel issues can typically be managed through diet, adequate fluid intake, physical activity and medication.

*Pain-Pain syndromes are common in MS. In one study, 55% of people with MS had “clinically significant pain” at some time, and almost half had chronic pain.

*Cognitive changes-Refers to a range of high-level brain functions affected in 50% of people with MS, including the ability to learn and remember information, organize and problem-solve, focus attention and accurately perceive the environment.

*Emotional changes-Can be a reaction to the stresses of living with MS as well as the result of neurologic and immune changes. Bouts of depression, mood swings, irritability, and episodes of uncontrollable laughing and crying pose significant challenges for people with MS and their families.

*Depression-Studies have suggested that clinical depression — the severest form of depression — is among the most common symptoms of MS. It is more common among people with MS than it is in the general population or in persons with many other chronic, disabling conditions

Less common symptoms:

*Speech problems-this including slurring (dysarthria) and loss of volume (dysphonia) occur in approximately 25-40% of people with MS, particularly later in the disease course and during periods of extreme fatigue. Stuttering is occasionally reported as well.

*Swallowing problems — referred to as dysphagia — result from damage to the nerves controlling the many small muscles in the mouth and throat.

*Tremor, or uncontrollable shaking, can occur in various parts of the body because of damaged areas along the complex nerve pathways that are responsible for coordination of movements.

*Seizures — which are the result of abnormal electrical discharges in an injured or scarred area of the brain — have been estimated to occur in 2-5% people with MS, compared to the estimated 3% of the general population.

*Breathing Problems-Respiration problems occur in people whose chest muscles have been severely weakened by damage to the nerves that control those muscles.

*Itching-Pruritis (itching) is one of the family of abnormal sensations — such as “pins and needles” and burning, stabbing or tearing pains — which may be experienced by people with MS.

*Headaches-Although headache is not a common symptom of MS, some reports suggest that people with MS have an increased incidence of certain types of headache. 

*Hearing Loss-About 6% of people who have MS complain of impaired hearing. In very rare cases, hearing loss has been reported as the first symptom of the disease.
