The main goal of treatment is to treat shock and preserve kidney function. Initially this is done through the administration of generous amounts of intravenous fluids, usually isotonic saline (0.9% weight per volume sodium chloride solution). In victims of crush syndrome, it is recommended to administer intravenous fluids even before they are extracted from collapsed structures. This will ensure sufficient circulating volume to deal with the muscle cell swelling (which typically commences when blood supply is restored), and to prevent the deposition of myoglobin in the kidneys. Amounts of 6 to 12 liters over 24 hours are recommended. The rate of fluid administration may be altered to achieve a high urine output (200–300 ml/h in adults), unless there are other reasons why this might lead to complications, such as a history of heart failure.

While many sources recommend additional intravenous agents to reduce damage to the kidney, most of the evidence supporting this practice comes from animal studies, and is inconsistent and conflicting. Mannitol acts by osmosis to enhance urine production and is thought to prevent myoglobin deposition in the kidney, but its efficacy has not been shown in studies and there is a risk of worsening kidney function. The addition of bicarbonate to the intravenous fluids may alleviate acidosis (high acid level of the blood) and make the urine more alkaline to prevent cast formation in the kidneys; evidence suggesting that bicarbonate has benefits above saline alone is limited, and it can worsen hypocalcemia by enhancing calcium and phosphate deposition in the tissues. If urine alkalinization is used, the pH of the urine is kept at 6.5 or above. Furosemide, a loop diuretic, is often used to ensure sufficient urine production, but evidence that this prevents kidney failure is lacking.

Hospitalization and IV hydration should be the first step in any patient suspected of having myoglobinuria or rhabdomyolysis. The goal is to induce a brisk diuresis to prevent myoglobin precipitation and deposition, which can cause acute kidney injury. Mannitol can be added to assist with diuresis. Adding sodium bicarbonate to the IV fluids will cause alkalinzation of the urine, believed to reduce the breakdown of myoglobin into its nephrotoxic metabolites, thus preventing renal damage. Often, IV normal saline is all that is needed to induce diuresis and alkalinize the urine.

In the initial stages, electrolyte levels are often abnormal and require correction. High potassium levels can be life-threatening, and respond to increased urine production and renal replacement therapy (see below). Temporary measures include the administration of calcium to protect against cardiac complications, insulin or salbutamol to redistribute potassium into cells, and infusions of bicarbonate solution.

Calcium levels initially tend to be low, but as the situation improves calcium is released from where it has precipitated with phosphate, and vitamin D production resumes, leading to hypercalcemia (abnormally high calcium levels). This "overshoot" occurs in 20–30% of those people who have developed kidney failure.

Treating proteinuria mainly needs proper diagnosis of the cause.

The most common cause is diabetic nephropathy; in this case, proper glycemic control may slow the progression. Medical management consists of angiotensin converting enzyme (ACE) inhibitors, which are typically first-line therapy for proteinuria. In patients whose proteinuria is not controlled with ACE inhibitors, the addition of an aldosterone antagonist (i.e., spironolactone) or angiotensin receptor blocker (ARB) may further reduce protein loss. Caution must be used if these agents are added to ACE inhibitor therapy due to the risk of hyperkalemia.

Proteinuria secondary to autoimmune disease should be treated with steroids or steroid-sparing agent plus the use of ACE inhibitors.

Common pharmacological treatments include:

- Mast cell stabilizers, including cromolyn sodium and natural stabilizers such as quercetin

- H1-antihistamines, such as cetirizine or ketotifen

- H2-antihistamines, such as ranitidine or famotidine

- Antileukotrienes, such as montelukast or zileuton as well as natural products (e.g., curcumin or St. John's wort extracts)

- Nonsteroidal anti-inflammatory drugs, including aspirin can be very helpful in reducing inflammation in some patients, while others can have dangerous reactions

Fillers, binders and dyes in many medications are often the culprit in causing reactions, not necessarily the active agent, so alternative formulations and compounding pharmacies should be considered.

Lifestyle changes may also be needed. Avoidance of triggers is important. It should be emphasized that MCAS patients can potentially react to any new exposure, including food, drink, medication, microbes and smoke via inhalation, ingestion or touch.

A low histamine diet and other elimination diets can be useful in identifying foods that trigger or worsen symptoms. Many MCAS patients already have high histamine levels, so ingesting foods with high histamine or histamine liberators can worsen many symptoms such as vasodilation that causes faintness and palpitations.

There is no cure for MCAS. For most, symptoms wax and wane, but many can experience a general worsening trend over time. Lifespan for those with MCAS appears to be normal, but quality of life can range from mild discomfort to severely impaired. Some patients are impaired enough to be disabled and unable to work.

Supervised exercise programs have been shown in small studies to improve exercise capacity by several measures.

Oral sucrose treatment (for example a sports drink with 75 grams of sucrose in 660 ml.) taken 30 minutes prior to exercise has been shown to help improve exercise tolerance including a lower heart rate and lower perceived level of exertion compared with placebo.

Often, aggressive treatment is unnecessary for people with MSK disease that does not cause any symptoms (asymptomatic). In such cases, treatment may consist of maintaining adequate fluid intake, with the goal of decreasing the risk of developing kidney stones (nephrolithiasis). Cases of recurrent kidney stone formation may warrant evaluation for possible underlying metabolic abnormalities.

In patients with low levels of citrate in the urine (hypocitraturia) and incomplete distal renal tubular acidosis, treatment with potassium citrate helps prevent the formation of new kidney stones. Urinary tract infections, when they occur, should also be treated.

Patients with the more rare form of MSK marked by chronic pain typically require pain management. Non-obstructing stones in MSK can be associated with significant and chronic pain even if they're not passing. The pain in this situation can be constant. It is not certain what causes this pain but researchers have proposed that the small numerous stones seen in MSK may cause obstruction of the small tubules and collecting ducts in the kidney which could lead to the pain. This pain can often be debilitating and treatment is challenging. Narcotic medication even with large quantities is sometimes not adequate. Some success with pain control has been reported using laser lithotripsy (called “ureteroscopic laser papillotomy”).

Myoglobinuria is the presence of myoglobin in the urine, usually associated with rhabdomyolysis or muscle destruction. Myoglobin is present in muscle cells as a reserve of oxygen.

Treatment in DOCK8 deficiency focuses on preventing and treating infections. Broad-spectrum antibiotics are a common mode of treatment when infection is present, though some infections (like lung abscesses) require surgical treatment. Pneumatocele may be treated with surgery, but the benefit is unclear.

Surgical treatment is also recommended for skin abscesses, along with topical and systemic antibiotics and antifungals.

Long-term treatment with systemic antibiotics, including trimethoprim/sulfamethoxazole, penicillins, and cephalosporins, is effective in preventing skin and lung infections. Other treatments used in DOCK8 deficiency include sodium cromoglycate, which improves white blood cell function, and isotretinoin, which improves skin condition.

Sometimes, Intravenous immunoglobulin is used as a treatment, but its benefits have not been proven. Levamisole is also ineffective. Mixed clinical outcomes have been found with interferon gamma and omalizumab. Though early research on hematopoietic stem cell transplantation was equivocal, later research has shown it to improve immune function. Two patients have been cured by bone marrow transplantation. Cyclosporine A is a current topic of research; preliminary results have shown it to be effective.

What happens after your child is diagnosed with CRMO/CNO?

Find a doctor who has experience with patients with CRMO/CNO. CRMO/CNO in children is generally treated by a pediatric rheumatologist. Ask your doctor for a referral.

Why do we treat CRMO/CNO?

- Reduce inflammation

- Prevent bone damage and bone deformities

- Decrease pain

How is CRMO/CNO treated?

CRMO/CNO is different for each patient. Not every child responds to every treatment. Your doctor may need to try several medications before finding the one that works for your child. In severe cases, doctors may combine medications to treat the disease. Your doctor will work with you and your child to help find the best treatment.

For some CRMO/CNO patients, the disease can be managed with non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs are the first line treatment. However, if NSAIDs are not effective, or if your child does not tolerate NSAIDs well, second line treatments are available.

First line treatments include Naproxen (Aleve), Celecoxib (Celebrex) Meloxicam (Mobic), Piroxicam (Feldene), Indomethacin (Indocin), Diclofenac (Voltaren).

Second line treatments include corticosteroids (Prednisone/Prednisolone), Methotrexate (Otrexup, Rasuvo, Trexall), Sulfasalazine (Azulfidine), Pamidronate (Aredia), Zolendronic Acid (Zometa), Adalimumab (Humira), Etanercept (Enbrel), Infliximab (Remicade).

These medications are also used in children with other inflammatory and/or bone conditions. Side effects may occur while taking these medications. Your physician will have a discussion with you prior to starting any new treatment.

Once a diagnosis is made, the treatment is based on an individual’s clinical condition. Based on the apparent activation of the mTOR pathway, Lucas and colleagues treated patients with rapamycin, an mTOR inhibitor. This effectively reduced hepatosplenomegaly and lymphadenopathy, most likely by restoring the normal balance of naïve, effector, and memory cells in the patients’ immune system. More research is needed to determine the most effective timing and dosage of this medication and to investigate other treatment options. Investigators at the National Institute of Allergy and Infectious Diseases at the US National Institutes of Health currently have clinical protocols to study new approaches to the diagnosis and treatment of this disorder.

Immediate treatment of drug induced OGC can be achieved with intravenous antimuscarinic benzatropine or procyclidine; which usually are effective within 5 minutes, although may take as long as 30 minutes for full effect. Further doses of procyclidine may be needed after 20 minutes. Any causative new medication should be discontinued. Also can be treated with 25 mg diphenhydramine.

Treatment of LPLD has two different objectives: immediate prevention of pancreatitis attacks and long term reduction of cardiovascular disease risk. Treatment is mainly based on medical nutrition therapy to maintain plasma triglyceride concentration below 11,3 mmol/L (1000 mg/dL). Maintenance of triglyceride levels below 22,6 mmol/L (2000 mg/dL) prevents in general from recurrent abdominal pain.

Strict low fat diet and avoidance of simple carbohydrates

Restriction of dietary fat to not more than 20 g/day or 15% of the total energy intake is usually sufficient to reduce plasma triglyceride concentration, although many patients report that to be symptom free a limit of less than 10g/day is optimal. Simple carbohydrates should be avoided as well. Medium-chain triglycerides can be used for cooking, because they are absorbed into the portal vein without becoming incorporated into chylomicrons. Fat-soluble vitamins A, D, E, and K, and minerals should be supplemented in patients with recurrent pancreatitis since they often have deficiencies as a result of malabsorption of fat. However, the diet approach is difficult to sustain for many of the patients.

Lipid lowering drugs

Lipid-lowering agents such as fibrates and omega-3-fatty acids can be used to lower TG levels in LPLD, however those drugs are very often not effective enough to reach treatment goals in LPLD patients. Statins should be considered to lower elevated non-HDL-Cholesterol.

Additional measures are avoidance of agents known to increase endogenous triglyceride levels, such as alcohol, estrogens, diuretics, isotretinoin, anidepressants (e.g. sertraline) and b-adrenergic blocking agents.

Gene therapy

In 2012, the European Commission approved alipogene tiparvovec (Glybera), a gene therapy for adults diagnosed with familial LPLD (confirmed by genetic testing) and suffering from severe or multiple pancreatitis attacks despite dietary fat restrictions. It was the first gene therapy to receive marketing authorization in Europe; it was priced at about $1 million per treatment, and as of 2016, only one person had been treated with it.

During an acute flare-up, therapy is targeted at reducing the inflammation present, and dilating the pupil. Mydriasis is important, as pupillary constriction is the primary reason for pain. Anti-inflammatory therapy is usually given both systemically, often in the form of flunixin meglumine, and topically, as prednisolone acetate. The mydriatic of choice is atropine. In the periods between acute attacks, no therapy has been shown to be beneficial.

Horses that suffer from this disease can never be considered cured, although they can be managed by careful use of the therapy described above, and fast detection of new flare-ups. If the disease is not properly treated, it will eventually lead to blindness.

Standard of care for treatment of CPT II deficiency commonly involves limitations on prolonged strenuous activity and the following dietary stipulations:

- The medium-chain fatty acid triheptanoin appears to be an effective therapy for adult-onset CPT II deficiency.

- Restriction of lipid intake

- Avoidance of fasting situations

- Dietary modifications including replacement of long-chain with medium-chain triglycerides supplemented with L-carnitine

Emergency treatment of cocaine-associated hyperthermia consists of administering a benzodiazepine sedation agent, such as diazepam (Valium) or lorazepam (Ativan) to enhance muscle relaxation and decrease sympathetic outflow from the central nervous system. Physical cooling is best accomplished with tepid water misting and cooling with a fan (convection and evaporation), which can be carried out easily in the field or hospital. There is no specific pharmacological antidote for cocaine overdose. The chest pain, high blood pressure, and increased heart rate caused by cocaine may be also treated with a benzodiazepine. Multiple and escalating dose of benzodiazepines may be necessary to achieve effect, which increases risk of over-sedation and respiratory depression. A comprehensive systematic review of all pharmacological treatments of cocaine cardiovascular toxicity revealed benzodiazepines may not always reliably lower heart rate and blood pressure.

Nitric-oxide mediated vasodilators, such as nitroglycerin and nitroprusside, are effective at lowering blood pressure and reversing coronary arterial vasoconstriction, but not heart rate. Nitroglycerin is useful for cocaine-induced chest pain, but the possibility of reflex tachycardia must be considered. Alpha-blockers such as phentolamine have been recommended and may be used to treat cocaine-induced hypertension and coronary arterial vasoconstriction, but these agents do not reduce heart rate. Furthermore, phentolamine is rarely used, not readily available in many emergency departments, and many present-day clinicians are unfamiliar with its use and titratability. Calcium channel blockers may also be used to treat hypertension and coronary arterial vasoconstriction, but fail to lower tachycardia based on all cocaine-related studies. Non-dihydropyridine calcium channels blockers such as diltiazem and verapamil are preferable, as dihydropyridine agents such as nifedipine have much higher risk of reflex tachycardia.

Agitated patients are best treated with benzodiazepines, but antipsychotics such as haloperidol and olanzapine may also be useful. The alpha-2 agonist dexmedetomidine may also be useful for treatment of agitation, but effects on heart rate and blood pressure are variable based on several studies and case reports. Lidocaine and intravenous lipid emulsion have been successfully used for serious ventricular tachyarrhythmias in several case reports.

The use of beta-blockers for cocaine cardiovascular toxicity has been subject to a relative contraindication by many clinicians for several years despite extremely limited evidence. The phenomenon of “unopposed alpha-stimulation,” in which blood pressure increases or coronary artery vasoconstriction worsens after blockade of beta-2 vasodilation in cocaine-abusing patients, is controversial. This rarely-encountered and unpredictable adverse effect has resulted in some clinicians advocating for an absolute contraindication of the use of all beta-blockers, including specific, non-specific, and mixed. Many clinicians have disregarded this dogma and administer beta-blockers for cocaine-related chest pain and acute coronary syndrome, especially when there is demand ischemia from uncontrolled tachycardia. Of the 1,744 total patients identified in the aforementioned systematic review, only 7 adverse events were from putative cases of “unopposed alpha-stimulation” due to propranolol (n=3), esmolol (n=3), and metoprolol (n=1). Some detractors of beta-blockers for cocaine-induced chest pain have cited minimal acute mortality and the short half-life of the drug, making it unnecessary to aggressively treat any associated tachycardia and hypertension. However, the long-term effect of cocaine use and development of heart failure, with early mortality, high morbidity, and tremendous demand on hospital utilization should be taken under consideration.

The mixed beta/alpha blocker labetalol has been shown to be safe and effective for treating concomitant cocaine-induced hypertension and tachycardia, without any “unopposed alpha-stimulation” adverse events recorded. The use of labetalol is approved by a recent AHA/ACC guideline for cocaine and methamphetamine patients with unstable angina/non-STEMI.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

People with acute pyelonephritis that is accompanied by high fever and leukocytosis are typically admitted to the hospital for intravenous hydration and intravenous antibiotic treatment. Treatment is typically initiated with an intravenous fluoroquinolone, an aminoglycoside, an extended-spectrum penicillin or cephalosporin, or a carbapenem. Combination antibiotic therapy is often used in such situations. The treatment regimen is selected based on local resistance data and the susceptibility profile of the specific infecting organism(s).

During the course of antibiotic treatment, serial white blood cell count and temperature are closely monitored. Typically, the intravenous antibiotics are continued until the person has no fever for at least 24 to 48 hours, then equivalent antibiotics by mouth can be given for a total of 2–week duration of treatment. Intravenous fluids may be administered to compensate for the reduced oral intake, insensible losses (due to the raised temperature) and vasodilation and to optimize urine output. Percutaneous nephrostomy or ureteral stent placement may be indicated to relieve obstruction caused by a stone. Children with acute pyelonephritis can be treated effectively with oral antibiotics (cefixime, ceftibuten and amoxicillin/clavulanic acid) or with short courses (2 to 4 days) of intravenous therapy followed by oral therapy. If intravenous therapy is chosen, single daily dosing with aminoglycosides is safe and effective.

Treatment of xanthogranulomatous pyelonephritis involves antibiotics as well as surgery. Removal of the kidney is the best surgical treatment in the overwhelming majority of cases, although polar resection (partial nephrectomy) has been effective for some people with localized disease. Watchful waiting with serial imaging may be appropriate in rare circumstances.

Currently, purine replacement via S-adenosylmethionine (SAM) supplementation in people with Arts syndrome appears to improve their condition. This suggests that SAM supplementation can alleviate symptoms of PRPS1 deficient patients by replacing purine nucleotides and open new avenues of therapeutic intervention. Other non-clinical treatment options include educational programs tailored to their individual needs. Sensorineural hearing loss has been treated with cochlear implantation with good results. Ataxia and visual impairment from optic atrophy are treated in a routine manner. Routine immunizations against common childhood infections and annual influenza immunization can also help prevent any secondary infections from occurring.

Regular neuropsychological, audiologic, and ophthalmologic examinations are also recommended.

Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if the disease-causing mutation in the family is known.

In people who do not require hospitalization and live in an area where there is a low prevalence of antibiotic-resistant bacteria, an fluoroquinolone by mouth such as ciprofloxacin or levofloxacin is an appropriate initial choice for therapy. In areas where there is a higher prevalence of fluoroquinolone resistance, it is useful to initiate treatment with a single intravenous dose of a long-acting antibiotic such as ceftriaxone or an aminoglycoside, and then continuing treatment with a fluoroquinolone. Oral trimethoprim/sulfamethoxazole is an appropriate choice for therapy if the bacteria is known to be susceptible. If trimethoprim/sulfamethoxazole is used when the susceptibility is not known, it is useful to initiate treatment with a single intravenous dose of a long-acting antibiotic such as ceftriaxone or an aminoglycoside. Oral beta-lactam antibiotics are less effective than other available agents for treatment of pyelonephritis. Improvement is expected in 48 to 72 hours.

Patients presenting with this disease undergo antibiotic treatment and gammaglobulin transfusions. Antibiotics are used to fight off the pathogenic organisms and the gammaglobulin helps provide a normal balance of antibodies to fight the infection. Bone marrow transplantation may be an option in some cases.
