What is a Periodic Fever Syndrome? - Systemic Autoinflammatory Disease (SAID) SupportCleveland Clinic Menu Recurrent fever Overview What is a recurrent fever? A is part of the natural defense system of your body. Your immune system is the part of your body that works to fight diseases. When this system is activated, the temperature of your body heats. Typically, its average body temperature should be around 98.6° Fahrenheit (or 37° Celsius). A fever is a temperature of 100.4° Fahrenheit or higher. If you take the temperature of an orally or axillary child (armpit), you can get a reading that is up to a discount grade. To get the most accurate temperature reading, take the child's temperature straight. A recurrent fever is a fever that happens several times over a period of time. These fevers can sometimes be described as episodic, which means they come and go. A recurrent fever is one that appears again in a pattern. For example, your young child or young child may have fever every month. This type of fever is typically seen in young children, usually younger than 5 years (infants and young children in particular). The increased temperature lasts a few days and then disappears for a long time. The child is healthy and usually acts between fevers. Recurrent fever is one of the main symptoms of a collection of conditions called periodic fever syndromes. These are diseases that cause a person — usually a child — to have fever in a time-spaced pattern, without having a virus or bacterial infection. What is the difference between recurrent fever and classical fever? The main difference between a classic fever and a recurrent fever is the frequency with which it happens. If you have recurring fever, it lasts a few days, improves, disappears and returns after a period of time when you feel healthy. Recurrent fevers continue to occur and return over time. A classic fever is also often linked to an infection or virus. With recurrent fever, you may have a higher body temperature without any viruses or bacterial infection. Possible causes What causes recurrent fever? The fever can occur for many different reasons. These causes may include: You may also have a higher body temperature at different times of the day or after exercise. These are usually only a few degrees higher than your normal body temperature and come back down after a short period of time. However, a recurrent fever is not caused by a virus or bacterial infection. Recurrent fevers seem to occur without a cause and pattern. It often appears as a main symptom of different periodic fever syndromes. These syndromes are sometimes caused by a genetic defect. When recurrent fever is linked to regular fever syndrome, the highest body temperature could be the result of one of these genetic problems. What medical conditions are linked to recurrent fevers? A recurrent fever is one of the main symptoms of a group of diseases called periodic fever syndrome. There are several types of , including: What are the symptoms of a recurrent fever? Symptoms of a recurrent fever are very similar to a typical fever. These symptoms may include: In children with fever, you may notice that your child is acting a little more tired than normal. Other signs of fever in a small child may include: Each child is different and although some may show many of these symptoms, others may show few or even no signs of discomfort. Some children with low-grade fever may not show any of these signs. They can act normally, playing and staying in a generally good mood. Care and treatment How to treat a recurrent fever? A recurrent fever is treated as a typical fever. Taking acetaminophen (Tylenol®) is a way to manage any uncomfortable symptoms of fever and reduce temperature. This is particularly useful in children. However, be sure to talk to your health care provider before giving acetaminophen to your child. The amount of medication (dose) that gives your child may vary depending on the child's weight and age. Make sure you double the correct dose before giving something to your child. You can usually give your child acetaminophen of birth. After 6 months of age, you can also give your ibuprofen child (Motrin®). Talking about medicine, make sure you avoid aspirin. This particular medicine can lead to a serious medical condition called Reye syndrome. It's very dangerous, so don't give your child aspirin until your health care provider tells you it's safe to do it. Rest is another important part of recovering from a fever. If you notice that your child is more tired than normal, let them rest. Drink plenty of fluids (especially water) is important when you have a fever. Make sure your child continues to take water and other fluids during a fever to prevent dehydration. It's important to watch your child during the fever. If your child is acting well for a few days, he can usually give acetaminophen to help with any discomfort and simply follow the fever. During this time, watch how much your child is drinking (hydration) and peeing. Also follow up on any changes in breathing patterns, especially if your child is working harder to breathe. If the fever continues for five days, your child will have to be seen by the health care provider. Following fever can also be useful. Note what temperatures happened when and how long the fever lasted. This information can help your health care provider with a diagnosis if your child continues to receive fevers on and off. These recurrent fevers can be a sign of a larger medical condition. Recurrent fevers last in adulthood? Most recurrent fevers disappear when the child is old. They are much more common in younger children than in adults. When to Call the Doctor When should I call my health care provider about my child's fever? In most cases, a low fever is not something to worry about. This is a sign that the body is doing what it should do to fight a disease. Most fevers usually disappear in a few days. However, it is always good to call your health care provider if you are a child has a high fever (104° Fahrenheit or higher) or if the fever lasts longer than a few days. If your child has fever for a long period of time, make an appointment with your child's pediatrician. This is the first date. If your pediatrician thinks these recurrent fevers could be regular fever syndrome, you will be connected to a specialist to diagnose your child and work on a treatment plan. A Cleveland Clinic noteIt can be scary when your child has a fever. Remember that you can always call your healthcare provider to ask questions about your child's fever and get direction in your next steps. Often, childhood fevers are watched and treated with Tylenol® at home. It is also a good idea to follow the fever so that you can give your provider all the information necessary for a diagnosis later.

» Pediatrics OVERVIEW regular fever syndromes: What each practitioner needs to know Are you sure your patient has a regular fever syndrome? What are the typical findings of these diseases? Periodic fever syndromes (PFS) are a group of rare auto-inflammatory diseases characterized by inappropriate, uncontrolled and often spontaneous signs and symptoms of inflammation. Recurrent fever ≥ 38°C is the cardinal characteristic in each PFS. Recurrent fever episodes occur in the absence of infection or evidence of active autoimmunity. Fevers in the PFS are due to anomalies in the activation of the innate immune system. Fever and swelling attacks can last days to weeks apart by good health intervals for weeks to months. The pattern of fever (duration and periodicity) and clinical characteristics are variables between syndromes and patients. The associated symptoms usually resolve spontaneously when the patient becomes feverish. However, in severe cases of hereditary disease, inflammation can be chronic with persistent symptoms and the development of long-term complications. The initiation of symptoms is usually in childhood, but may be delayed until adolescence or later. For an individual patient, there is often a predictable pattern of fever, a common constellation of associated symptoms and a similar course of acute disease. Most PFSs are inherited and share the following characteristics: Symptom constellation, including fever pattern, associated symptoms, acute phase response, family history and ethnic origin suggest diagnosis that can be confirmed by genotyping. Significant long-term morbidities and higher mortality occur in untreated patients. Increased risk of illness and secondary amyloidosis in certain ethnic groups. Due to defects of single genes encoding proteins involved in controlling inflammatory pathways, cytokines and apoptosis mediating innate immune responses. Genotipate can guide long-term treatment and prognosis. Hereditary PFS:Mediterranean Fever (FFM)Hyperimmunoglobulinemia DF regular fever syndrome (HIDS)Tumoral (TNF) associated periodic syndrome (TRAPS)Recurrent syndromes associated with cyriopyrin (CAPS):Babym syndrome-Wells (MWS) Multisystem inflammatory disorder (NOMID) Cyccal diseaseCreditant lymphomas, or other chronic infections of the disease PFS is considered auto-inflammatory, not autoimmune, diseases that may or may not have specific triggers. When present, triggers may include cold, heat, stress, surgery, concurrent infection, pregnancy, and vaccines. The clinical manifestations of PFS are due to the inappropriate activation and regulation of antigenoindependent inflammation (innate immunity). Most PFSs are due to defects of unique genes that bind proteins in the path of inflammation control, cytokines production or cell death. What laboratory studies should you ask to help confirm the diagnosis? How should you interpret the results? Bleeding, Bleeding, Bleeding, Bleeding, Bleeding, Bleeding, Bleeding, Bleeding, Bleeding, Bleeding Positive serologies of IgM, PCR or cultures suggest infection. Elevado ACE suggests sarcoidosis. Positive PPD suggests tuberculosis. High uric acid, especially if there is associated leucocytosis or thrombocytopenia, suggests leukemia. ANA ≥1:320, positive lupus serologies, or ANCA suggests a possible systemic autoimmune disease. Hypogammaglobulinemia suggests secondary infection of primary immunodeficiency. Hypergammaglobulinemia suggests HIV or systemic autoimmune disease. Suspectful suspects if IgD is raised with or without IgA elevated and IgG normal and IgM. Would imaging studies be useful? If so, what? Chest X-ray may be useful when infection, lung inflammatory disease, or seroitis (pleuritis, pericarditis) is suspected. Abdominal or ultrasound X-rays may be indicated to evaluate abdominal pain, or to help rule out peritonitis or a surgical emergency. A CT scan of the neck, chest, abdomen, or pelvis may be needed to evaluate lymphadenopathy, lung inflammatory disease, serositis or splenomegaly. The echocardiogram is indicated to evaluate chest pain and rule out pericarditis. Consider the analysis of bone gallon to rule out osteomyelitis. Consider joint RRM with and without contrast for arthritis. Consider magnetic resonance with and without contrast, and MRA to evaluate for CNS vasculitis and causes of headache, developmental delay or hearing loss.

There are some significant morbidities and growing mortality rates observed in patients not treated with inherited PFS syndromes: periodic syndromes associated with cyclopoin, CAPS (FCAS, MWS, NOMID/CINCA): Each of these syndromes is due to a autosomal dominant mutation in a single gene, NLRP3. Phenotypes and complications are different between FCAS, MWS and NOMID, although a significant overlap is observed. Everyone shares a characteristic urtical eruption, but the fever may or may not be present. The most severe disease is seen in NOMID, followed by MWS and FCAS. The 2° amyloidosis frequency is higher in MWS, followed by NOMID and then FCAS. FCAS (fertile cold self-inflammation syndrome): Generally diagnosed at birth or within the first 6 months of life, based on urticary eruption attacks and fever caused by cold exposure and lasting less than 24 hours. These patients usually have a normal life, but 2° amyloidosis occurs in up to 5% of patients. Daily fatigue, headache and myalgia, even without exposure to the cold, contribute to considerable morbidity. MWS (Muckle-Wells syndrome): Characterized by recurrent but unpredictable fever attacks 38.5° C and hives for 1-3 days, although some symptoms may persist. The starting age is often 90%) and the progressive loss of sensorineural hearing (concentr70%) are pathogenic. Since the fever pattern is less predictable than in FCAS, the diagnosis of MWS is often delayed until hearing loss is observed during adolescence. All patients suffer from severe chronic fatigue, which is referred with IL-1 blockage. Abdominal pain and headaches occur in most patients during the fever, but these are not as severe as in the FMF. Arthralgias are more common than chronic arthritis. Recurrent oral aphtase occurs in patients with mento50% during fevers. NOMID/CINCA (inflammatory disease with multiple neonatal connection systems / chronic childhood neurological joint syndrome): This is the most severe form of CAPS, with chronic urticaria with or without a fever noted at birth or in the newborn period. Continuous symptoms and frequent bengales are not necessarily accompanied by fever. Unlike other PFSs, NOMID follows a chronic course with significant complications, general poor prognosis and shortened life if not treated (by IL-1 block therapy). Early diagnosis and treatment with IL-1 inhibition improves quality of life and delays or prevents morbidities. Severe CNS manifestations are observed in 90% of nontreated patients. The epiphysial arthropathy of overcrowding is patonomonic and develops in 30%-60% of patients. Secondary amyloidosis develops in 10%-25% of patients. Other complications vary in severity and age of appearance, but include: ̊ Delay in early growth, delayed puberty Skull abnormalities, frontal head ̊ Progressive loss of sensorineural hearing from early childhood in √70%. Chronic aseptic meningitis, often with chronic headache, papilloma and increased intracranial pressure Mild arthritis in √65%, but 30%-60% develop early chronic inflammation of severe joints with characteristic epiphyseal overgrowth, especially of patellae, with progressive joint contractures and limited mobility ̊ Cognitive effectivity. Chronic intraocular inflammation by 50% manifested by previous uveitis/posterior resistant to treatment, optical atrophy and severe vision loss by 25% or blindness. Hyperimmunoglobulinemia D with regular fever syndrome (HIDS) Attacks can begin in the first year of life with a medium age to an initial attack of 6 m. All patients have their disease at the beginning of 5 years, although the diagnosis is often delayed unless there is a family history of HIDS. Clinical attacks are characterized by non-referent fever ≥ 38.5°C for 3-7 days, in recurrent cycles every 4-8 weeks. Prodrome symptoms such as chills, fatigue, and URI are common. Cervical lymphadenopathy pronounced occurs in √90% and splenomegaly is observed in 50% (distinguishing HIDS from other PFS). Rebounds of severe abdominal pain due to serositis may result in unnecessary exploratory laparotomy or appendicectomy procedures. Non-destructive arthritis or arthralgia occur in 80%. Chronic rashes are observed in Â80% and are variable in appearance. Patients with HIDS usually have a normal life with few serious complications that are not 2° amyloidosis (in family Mediterranean fever (FFFFF)The initial attack of FMF usually occurs in early childhood; 80%-90% are 38° C and abdominal pain for 1-3 days repeating every 3-8 weeks. Patients are asymptomatic and generally good health among attacks. The main cause of mortality is amyloidosis of 2° that leads to kidney failure: Before the cochicin: 2° of amyloidosis occurred in 60%-75% of patients with 40 years of age; in 30% of Sephardic Jews, 60% of Turks; √75% of North African Jews. Country of origin (Turkey, Armenia, Arab nations) and M694V mutation in MEFV gene associated with increased risk of amyloidosis. Some patients have amyloidosis as the first clinical manifestation of the FMF. Continuous colquicine prevents amyloid-related nephropathy in most patients. In the cochicina: 95% improvement, 70% shipping,10%-15% develops amyloidosis 2°. Diagnosis can be confirmed in symptomatic people without identifiable MEFV mutations, if the six-month trial of colchicin remittance attacks is repeated after the suspension of the cochicin. Complications/morbidities include: recurrent peritonitis in 90%, leading to unnecessary abdominal surgery, infertility, recurrent pleuritis intestinal obstruction in 45%; occasionally pericarditis Artritis mono oligo-in 75%. Current aseptical orchidMeningitisErytheme similar to erythema, but rare. Diagnosis in children requires ≥2 of 5 criteria: fever, abdominal pain, chest pain, arthritis and family history of the FFF. Recurrent and unpredictable outbreaks of prolonged fevers √38°C – 41°C, lasting 3 days to 6 weeks, are characterized by tumor necrosis factor (TRAPS)TRAPS. The episodes are repeated on average every 5-6 weeks. The age in the initial presentation is very variable: 50 yr; medium starter age: 3 yr. These patients usually have a normal life, but the previous mortality may be due to a 2° amyloidosis in 10% patients. Other important morbidities include: RashMigratory myalgias monoarticular arthritis, which often precedes fever, are cardinal characteristics Ocular inflammation at 80%Abdominal painTable VI summarizes the risks and benefits of treatment options available for CAPS.

Epidemiology: FMF: Most common hereditary PFS. Predominantly affects people living in the Mediterranean region. Incidence: 1-3/105 in Turkey, Armenia, North Africa, Arab countries and Italy; rare in other places. Clinical symptoms and the range/frequency of individual mutations in Arabs differ from other ethnic groups and vary according to the country of birth. Carrier Rate: 1:3 – 1:7 in Jews, Armenians and Turks in North Africa and Iraqis who have serious illnesses and increase amyloidosis. 1:5 in Ashkenazi Jews, but the prevalence of diseases is lower, since the most common mutation is associated with mild disease. Thin male predominance (13:10). TRAPS:Incidence: rare (5-6/107 person-yr in Germans). Many of the Scottish or Irish ancestors; as a result, initially called Fiebre Hiberniano Familial. It affects women and men alike. HIDS:Incidence: Very rare (frequency of the 1:350 mutation in the secondary Holland to the founding effect. Conf.60% of the Dutch or French descent and generally Caucasian. Men and women equally affected. FCAS: Many of the European ancestry. Incidence: very rare. MWS: Most reported in Europe and North America, but limited data from other areas. Incidence: rare, generally familiar. Equally affected men and women. NOMID:Most of those reported frequently in Europe and North America, but limited data from other areas. Incidence: rare. Less likely FCAS or MWS are family members. Genetics: FMF: autosomal recessive mutations (homozygous or composite heterocigous) (conejército 50) in the MEFV gene encoding pyrin/marenostrin. Four mutations of evidence in exon 10 (M680I, M694V, M694J and V726A) and E148Q in exon 2 represent most mutations. All mutations decrease the function of pirin30% of symptomatic patients, including mandatory carriers, have only one identifiable MEFV mutation. Diagnosis should never be excluded on the basis of genetic tests only if clinical characteristics are observed. The M694V mutation is more common, confers greater gravity and risk of amyloidosis and predominates in Jews, Armenians and Turks from North Africa and Iraqi. In the Jews of Ashkenazi, the most common mutations (V726A and E148Q) have reduced penetration and conferred a milder phenotype of disease. TRAPS: autosomal dominant mutations in TNFRSF1A genes that used the 55 kDa TNF receptor with incomplete disease penetration. ratio mutations almost exclusively affect the extracellular part of the TNF receptor. Many patients with TNFRSF1A clinical characteristics have not identified TNFRSF1A mutations. HIDS: Homozygous or heterocigous compound mutations in mevalonated kinase (MVK) gen encoding mevalonate kinase. 80% carry at least one V377I mutation. mutations. CAPS (FCAS, MWS, NOMID): dominant autosomal (gain) mutations in the NLRP3 (CIASI) cryptopyrin/NLRP3.10% FCAS, 25% MWS and 30%-50% NOMID/CINCA lacks NLRP3 identification mutations. Inflammatory and Innate Immunity The distinctive seal of innate immunity is the rapid generation and release of pro-inflammatory cytokines, including IL-1beta, TNF-alpha and IL-6, in response to "danger signs" as microbial products, toxins and metabolic stress. Il-1 beta is the pleiotropic pyrogen and the alarm cytokine. Its activation triggers a waterfall of events that result in inflammation and production of other pro-inflammatory cytokines. Activation of the multiprotein intracellular complex called "inflammatory" by signs of danger in neutrophils, macrophages, dendritics and other cells is essential for the release of bioactive IL-1 and the initiation of inflammation. Inflammasome is composed of NLRP3, cocoa-1 and ASC (apoptosis-associated) protein similar to that of mota). Inflammatory stimulation activates the hose-1, which converts IL-1beta to its bioactive form. Mutations in one or more of the proteins that include inflammatory and subsequent effects on IL-1beta activity have been shown to cause inherited fever syndromes on a regular basis. How do these pathogens/genes/exhibitions cause the disease? CAPS (FCAS, MWS, NOMID): NLRP3 required for the assembly of a multiprotein or "inflammatory" complex in phagocytic cells, monocytes, macrophages, dendrite cells and condrocytes that link the initial detection of the danger of microbial products and metabolic stress to the activation of the innate immune system through the production of the IL-1beta alarm cytokine.Considered "inrinsic inflammasomopathies" – diseases resulting from the growing secretion. Function mutations in NLRP3 cause the activation of the constitutive inflammatory and increase the activity of the hose-1, resulting in excessive release of IL-1beta, uncontrolled inflammation and tissue injury. FMF: The FMF is considered an extrinsic "inflammasomopathy". The pirin plays an intrinsic role in regulating the function of granulocyte and monocyte during inflammatory responses. Pyrin interacts with ASC and disrupts NLRP3-ASC interactions, which inhibits NF-kappa Activation B and apoptosis. The abduction of ASC by pirin prevents the activation of caspase-1. Operating Loss MEFV mutations decrease pirin binding to ASC, which leads to inflammatory activation and increases IL-1beta secretion. Colchicin inhibits neutrophil chemotaxis through the depolymerization of microtubules and reduces the production of pro-inflammatory cytokines through the inhibition of NF-kappaB activation. HIDS: Mevalonated kinase (MVK) is necessary for cholesterol synthesis. MVK catalyzes the conversion of mevalonic acid to 5-phospho-mevalonic acid in the isoprenoid pathway. Severe mutations of loss of functions with absent MVK activity cause mevalonic aciduria, an innate error of metabolism associated with developmental delay and early death. Less severe mutations (known 60) with residual MVK activity of 1%-15% cause HIDS. Etiology of high serum IgD and also IgA (in ю70%) recurrent fevers of decreased MVK activity not fully understood, but includes increased inflammatory activation and overproduction IL-1beta. TRAPS: The soluble TNF cell surface and receptors unite the pro-inflammatory cytokine, TNF, with opposite effects on signaling TNF receptors and TNF secretion during inflammatory responses. Some mutations affect the coating of receptors, allowing sustained stimulation of membrane TNF receptors and lower availability of TNF soluble receptors (short extracellular portions) that work to inhibit more TNF signaling. Most mutations affect the folding and traffic of TNR receptors to the cell membrane, leading to intracellular accumulation of mutant receptors that spontaneously induce the activation of protein kinase in several inflammatory pathways. Other mutations decrease TNF binding to the ligated membrane receptor, inhibiting TNF-dependent apoptosis pathways involved in the control of inflammation. Other clinical manifestations that could help with diagnosis and managementAmyloidosis secondaria in hereditary PFS: Medical management focused on the prevention of 2° amyloidosis. Development of highly variable amyloidosis between different PFSs, but always devastating. Aloid deposition in the kidneys in 90% of patients and usually presents as proteinuria without kidney failure. Kidney failure due to amyloidosis can be the first symptom of the disease. Proteinuria in disease presentation or with follow-up requires a 24-hour urine collection for the cleaning of proteins and creatinine. Amyloidosis diagnosed by kidney or rectum biopsy. Consider renal and/or rectal biopsy if the protein √500 mg in 24-hour urine collection or BUN/creatinine elevation. Average survival time: 2453 m from the time of diagnosis without treatment. Amyloidosis in the GI tract in 20% patients; it presents as diarrhea and malabsorption. Heart involvement of 2° amyloidosis due to chronic inflammation is rare, unlike other types of amyloidosis. The level of amyloid serum A (SAA) may reflect active amyloid deposition and guidance therapy. Cooking prevents renal amyloidosis in the FMF, but not in HIDS, TRAPS or CAPS. Genotype: phenotype correlations and controversies that affect treatment decisions in FMF:Homozygous patients for M694V mutation or composite heterozygous for M694V and other disease-causing mutation (V726A-E148Q) should initiate chronic cochicin therapy as soon as the diagnosis confirmed by genotyped. Patients homozygous for V726A-E148Q or composite heterozygous for V726A-E148Q and other disease-causing mutation (not M694V) should receive colchicin at the beginning of attacks and not necessarily chronic cochicin unless severe inflammation, proteinuria or amiodosis occurs. Patients without M694V or V726A-E148Q mutations and mild symptoms may not need colchicin unless the attacks are severe or develop amyloidosis, which would be unlikely. Diagnosis and treatment with colchicin should not be excluded in individuals with typical clinical symptoms that lack identifiable MEFV mutation. What complications can you expect from disease or treatment of the disease? Most self-limited complications, but some affect health and quality of life, including unnecessary abdominal surgery and secondary infertility to pelvic adhesions, as well as unique morbidities to NOMID. The complication of the most worrying disease is amyloidosis of 2°, which is the main cause of morbidity and mortality. Treatment complications can be more common than those of the disease, including the worsening of inflammation, organ toxicity, infection and future malignancy. Are there additional laboratory studies available; even some that are not widely available? Serum amyloid A protein (SAA) urinary mevalonic acid level TNF receptor level How can PFS be prevented? No known prevention. Genetic counselling is suspected to be important if PFS is inherited. Prenatal diagnosis requires identification of disease-causing mutations.

Continuous discussions with regard to etiology, diagnosis, treatment Long-term risks/benefits of treatment with biologics, given uncertainties of future risks, especially for malignant neoplasms, opportunistic infections, autoimmune diseases, organ toxicity. Best PFAPA management: steroids vs tonsillectomy vs IL-1 blockage vs non-treatment. Use of colchicin for treatment or prophylaxis in patients with FMF with a non-M694mutation identified or mild presentation. The role of pharmacogenomy in managing regular fever syndromes.
