Kartagener syndrome is a congenital condition in which half of the patients have situs inversus, a mirror-image reversal of the internal organs.42 Patients may exhibit chronic, thick, mucoid rhinorrhea from early in childhood. Examination usually reveals pale and swollen nasal mucosa, mucopurulent secretions, and an impaired sense of smell. Nasal polyps are noted in 30% of affected individuals.Jones, Kenneth Lyons.

In the 1970s, Bjorn Afzelius (d. 2008) 9 a cell biologist with an interest in electron microscopy, noted the diversity of structural defects which can affect the dynein arms and/or radial spokes of the tail of immotile sperm 3. While investigating rare cases of men with immotile spermatozoa, he noted a frequency of situs inversus and dysfunction of other ciliated organs 8. It was Afzelius who made the connection with the syndrome previously described by Kartagener. The importance of Afzelius's work is the reason that some now call the eponymous condition, Kartagener-Afzelius syndrome 10.

The alert, issued by NHS England, said there was a growing concern that a coronavirus-related inflammatory syndrome is emerging in children in the UK or that there may be another, as yet.. “Bronchiectasis” is the pathologic term for bronchial destruction, bronchial dilation, and accumulation of infected secretions, which occurs most often in the setting of chronic lung infections. Although cystic fibrosis (CF) is the most frequent genetic condition associated with bronchiectasis, primary and secondary immunodeficiencies and ciliary dysfunction also may result in chronic pulmonary infections and lung tissue destruction, especially in dependent areas of the lung. Because more than two thirds of children with non–CF-related bronchiectasis have evidence of an immune defect, primary ciliary dyskinesia, or recurrent aspiration, evaluation of patients with this finding should include immunologic and other diagnostic studies to rule out these other etiologies.17 Several genetic syndromes with bronchiectasis as a major feature have been described that are associated with a primary immunodeficiency (Table 14-12).Adenylate kinase type 7 (AK7), the mediator of the reaction of ADP to ATP and AMP, is also diminished significantly in patients with primary ciliary dyskinesia compared with healthy controls. AK7 expression has also been correlated with ciliary beat frequency in this patient population.

Kartagener described a curious combination of situs inversus, chronic sinusitis, and bronchiectasis, which subsequently became known as the Kartagener triad. The term “Kartagener syndrome” was later adopted when additional features of rhinitis, nasal polyps, chronic otitis media, and reduced fertility were recognized. Kartagener syndrome is now considered the most severe clinical expression of a spectrum of abnormalities of ciliary motility caused by defective cilia in several parts of the body that renders ciliary function ineffective. This entity has been termed “immotile-cilia syndrome,” “dyskinetic cilia syndrome,” and, more appropriately, “primary ciliary dyskinesia” (PCD).18Nadel HR, Stringer DA, Levison H, Turner JA, Sturgess JM. The immotile cilia syndrome: radiological manifestations. Radiology. 1985 Mar. 154(3):651-5. [Medline]. Ciliated epithelium covers most areas of the upper respiratory tract, including the nasal mucosa, paranasal sinuses, middle ear, eustachian tube, and pharynx. The lower respiratory tract contains ciliated epithelium from the trachea to the respiratory bronchioles. Each ciliated cell gives rise to approximately 200 cilia that vary in length from 5-6 μm and decrease in size to 1-3 μm as the airway becomes smaller.

The syndrome with the most prominent association with Htx is PCD (Kartagener syndrome). PCD consists of sinopulmonary disease, male infertility, and a 50% incidence of abnormal cardiac situs.53 A minimum of 6.5% of patients with PCD have intracardiac disease consistent with Htx.73 PCD is caused by mutations in genes affecting function of motile cilia in the airway, the sperm flagellum, and the motile cilia found on the LR organizer during development. At this time, defects in 12 distinct genes have been associated with PCD (Table 17b-1), and the repertoire is increasing as genomic analysis of affected patients becomes more sophisticated. Inheritance is predominantly recessive, although rare dominant and X-linked pedigrees have been identified.Bush A, Chodhari R, Collins N, Copeland F, Hall P, Harcourt J.

Savant syndrome: realities, myths and misconceptions. J Autism Dev Disord. Treffert DA, Rebedew DL. The Savant Syndrome Registry: A Preliminary Report Efforts to standardise the clinical criteria for the diagnosis of KS have centred on dextrocardia, a ciliary beat frequency of less than 10 Hz/second and a mean cross-section dynein arm count of less than 2. If the patient does not have dextrocardia, the identification of primary ciliary dyskinesia becomes the mainstay of diagnosis. Genetic testing ultimately may become the principal means of establishing this diagnosis[13].

Recently a gene protein, CCDC40, has been characterized as playing an essential role in correct left-right patterning in mouse, zebrafish, and humans. In mouse and zebrafish, CCDC40 is expressed in tissues that contain motile cilia. Mutations in this protein result in cilia with reduced ranges of motility and likely result in a variant of primary ciliary dyskinesia characterized by misplacement of the central pair of microtubules and defective assembly of inner dynein arms and dynein regulatory complexes.

Adenoidectomy or adenotonsillectomy is usually the first-line surgical intervention for preschoolers, and it is often appropriate in older children. The expected rate of improvement is 70% to 80% (Goldsmith and Rosenfeld, 2003).Siewert had first described the different classic features of Kartagener Syndrome, which include bronchiectasis, sinusitis, and situs inversus. But a Swiss pediatrician Manes Kartagener first reported four cases in 1933. and  after that in 1960 other investigator reported 300 cases with classic features of Kartagener Syndrome, including congenital and generalised non-functioning of the cilia. The name of this syndrome is ensuing from the first reported  investigator.

Obstructive lung disease may be another component of Kartagener syndrome symptomatology. It probably results from elevated levels of local inflammatory mediators in a chronically irritated airway.

The final diagnosis of any of the PCDs, including Kartagener syndrome, rests on electron microscopic evaluation of respiratory cilia. Scraping of the anterior aspect of the inferior nasal turbinate or biopsy of the bronchial epithelium at the time of bronchoscopy may provide an adequate sample for ultrastructural analysis. The most frequent electron microscopic finding in patients with PCD is absence of, or abnormalities in, the dynein arms; about 1 in 10 ciliary samples has obvious abnormalities in the central pair of microtubules or in the radial spokes.

He was unaware of male infertility being part of the phenotype of the disease 8.The cause of primary ciliary dyskinesia is genetic, with an autosomal recessive inheritance pattern. Genome analysis has found primary ciliary dyskinesia to be genetically heterogenous. Genes DNAH5 and DNA11 on bands 5p15.1 and 9p13,3 respectively, are known to cause primary ciliary dyskinesia. Both genes encode for dynein. [9] There are more than 200 genes, however, that are predicted to be involved in cilia biology and may play a role in primary ciliary dyskinesia and other ciliopathies.

  1. Sturgess et al [6] described how the radial spoke, which serves to translate outer microtubular sliding into cilial bending, was absent in some patients with primary ciliary dyskinesia. Cilia in other patients lacked central tubules; however, instead of the central tubules, an outer microtubular doublet transposed to the cell of the axoneme was present that displayed an abnormal 8+1 doublet-to-tubule pattern. Both the radial spoke and the transposed doublet defects impaired mucociliary clearance.
  2. Advances in reproductive technology allow for men who have Kartagener syndrome to have the opportunity to have children. A procedure called intracytoplasmic sperm injection or ICSI, now allow immotile or dysmotile sperm to fertilize an egg. ICSI involves injection of a single sperm into single eggs in order for fertilization to occur. This procedure first involves ovulation induction and egg retrieval to obtain eggs for attempt at fertilization by ICSI. In Vitro Fertilization (ICSI) pregnancy rates vary from center to center. Overall pregnancy rates of 10%-40% have been quoted worldwide, utilizing these procedures.

Kartagener Syndrome Symptoms and Treatmen

  1. Some patients with clinical features of primary ciliary dyskinesia have a ciliary ultrastructure that appears normal, but their arrangement and beat direction is disoriented, which causes inefficient mucociliary transport. These findings illustrate the importance of analyzing ciliary motility and ultrastructure when considering a diagnosis of primary ciliary dyskinesia.

13 December 2019. Impeachment lesson plan: Up close to the impeachment Clinical manifestations include chronic upper and lower respiratory tract disease resulting from ineffective mucociliary clearance. Males demonstrate infertility secondary to immotile spermatozoa.One theory behind the association of situs inversus with the underlying cause of Kartagener syndrome is that the lack of ciliary movement in the developing embryo may result in incorrect organ rotation in approximately 50% of affected individuals. In fact, 50% of patients with PCD will have situs inversus and thus be diagnosed to have Kartagener syndrome. However, this is a theory supported only by some researchers.

The outer doublets are interconnected by nexin links, and each A subunit is attached to two dynein arms that contain adenosine triphosphatase; one inner arm and one outer arm. The primary function of the central sheath, radial spokes, and nexin links is to maintain the structural integrity of the cilium, whereas the dynein arms are responsible for ciliary motion.Chest radiographs may illustrate bronchial wall thickening (earliest manifestation), hyperinflation, atelectasis, bronchiectasis, and situs inversus (in 50% of patients with primary ciliary dyskinesia). High-resolution CT (HRCT) scanning, spirometry, and plethysmography may also be performed. Pifferi et al found that plethysmography better predicted HRCT abnormalities than spirometry by allowing recognition of different severities of focal air trapping, atelectasis, and extent of bronchiectasis in patients with primary ciliary dyskinesia. [20] Whether it might be a useful test to define populations of patients with primary ciliary dyskinesia who should or should not have HRCT scans requires further longitudinal studies. Magnin et al evaluated the longitudinal relationships between lung function tests (LFTs) and chest HRCT in children with primary ciliary dyskinesia and found significant correlation. It is possible that lung function follow-up can be used to reduce CT frequency to help minimize the radiation exposure in these children. [21] Kartagener syndrome is an autosomal recessive condition. This means that in order to have the condition, an individual needs to inherit two copies of the gene for the condition, one from each parent. Individuals who carry only one gene for an autosomal recessive syndrome are called heterozygotes. Heterozygotes for Kartagener syndrome have normal ciliary function and do not have any clinical features of the condition. If two carriers of Kartagener syndrome have children, there is a 25% chance, with each pregnancy, for having a child with Kartagener syndrome.Krawczynski MR, Witt M; PCD and RP: X-linked inheritance of both disorders? Pediatr Pulmonol. 2004 Jul38(1):88-9.

ESS is performed under general anesthesia using an oral preformed (RAE) or standard endotracheal tube. Many of these children have chronic disease or upper airway obstruction. The anesthetic approach is similar to that described for nasal polypectomy and adenotonsillectomy. The surgeon may elect to use topical oxymetazoline (0.25% to 0.50%) for initial vasoconstriction and then infiltrate the tissue with lidocaine (0.5%) and epinephrine (1:100,000 solution) for hemostasis. The surgeon and the anesthesiologist should be aware that the duration of vasoconstriction usually does not last longer than 1.5 hours, and when surgical procedures are not completed within this period, mild bleeding may make visualization of the surgical site difficult and present a potential problem postoperatively. Some surgeons routinely pack the nose with gauze after the procedure for hemostasis, and the patient becomes an obligate mouth breather. Other surgeons may elect to use Surgicel or FloSeal to obtain hemostasis, and each of these materials has the potential for migration into the lower airway.

Bronchial or nasal turbinate mucosal biopsy for electron microscopic evaluation of cilia. Kartagener syndrome is one of the ciliary dyskinesia (or immotile cilia) syndromes. The presenting symptoms are a constellation of recurrent pulmonary infections, chronic sinusitis, recurrent otitis media, situs inversus, and infertility (in males). Structural ciliary abnormalities (most common are absent dynein arms) result in abnormal ciliary beat frequency and decreased clearance of respiratory secretions, thereby predisposing the patient to infection. In addition, because spermatozoa have tails with the same ultrastructural abnormalities as respiratory cilia, they move less well, causing infertility. The cause of the situs inversus (Fig. 17-4) is not fully understood, but it occurs in about 50% of individuals with primary ciliary dyskinesia. It has been suggested that cilia are important for proper organ orientation during embryonic development and that dysfunctional cilia make organ orientation a random event, leading to situs inversus 50% of the time.Magnin ML, Cros P, Beydon N, et al.

The components that form the cilium contain several hundred different proteins. Each is coded for by different DNA sequences, potentially on different chromosomes . A defect in any of these codes could produce an abnormal or missing protein that is a building block for the cilium and thus could cause abnormal ciliary structure and movement, resulting in Kartagener syndrome.Chronic childhood infections can be very debilitating, but the range and severity of clinical symptoms is wide. In severe cases, the prognosis can be fatal if bilateral lung transplantation is delayed. [15] Fortunately, primary ciliary dyskinesia and Kartagener syndrome usually become less problematic near the end of the patient's second decade, and many patients have near normal adult lives. The prognosis of patients with Kartagener syndrome was outlined in a longitudinal study, which measured long-term outcomes and pulmonary function test results. Tests were conducted on an interval basis in a cohort of 74 patients. The study found that patients are at risk for decreased pulmonary function. The study did not come to a firm conclusion on age correlation with lung deterioration or disease progression. [16] However, cross-sectional data suggest that spirometry worsens in patients over time.It is suspected that visceral rotation in the embryo is dependent upon normal ciliary action - hence, the association between primary ciliary dyskinesia and situs inversus abnormality.

What is kartagener's syndrome? - Quor

Congenital defects, which should be considered in all patients include cystic fibrosis, Kartagener syndrome, alpha-1-antitrypsin deficiency, collagen defects (e.g. Marfan syndrome)Bronchiectasis may develop in young individuals, but is never present at birth; no individual is born with full-blown Kartagener syndrome. Although individuals with PCD, which includes Kartagener syndrome, are plagued by recurrent sinopulmonary infections and chronic otitis media, they do not have any recognized immunologic problem. Their infections are tied to structurally defective cilia, resulting in inability to clear secretions, with a buildup of mucus and bacteria in the respiratory tract.Greenstone M, Stanley P, Cole P, Mackay I. Upper airway manifestations of primary ciliary dyskinesia. J Laryngol Otol. 1985 Oct. 99(10):985-91. [Medline]. Individual having Kartagener’s syndrome can complete a normal lifespan. But the key factor for improved quality of life and normal survival is to regular consultation with  a doctor and follow the prescribed treatment plan to correctly control patient’s condition.

When the same condition can be caused by different genetic abnormalities, this is known as genetic heterogeneity. In fact, several different defects in cilia have been seen in association with Kartagener syndrome, including; overly long cilia, overly short cilia, absent cilia and randomly oriented cilia, suggesting genetic heterogeneity. Studies have suggested that the most common defect of cilia in Kartagener syndrome is the lack of dynein arms. There have been rare cases in which individuals have Kartagener syndrome, yet have no detectable abnormality of the cilia, even though the ciliary function is abnormal. Results of one study involving a genome-wide linkage search performed on 31 families, with multiple individuals affected with either PCD or Kartagener syndrome, strongly suggested extensive heterogeneity. Potential regions involving genes responsible for PCD or Kartagener syndrome were localized on chromosomes 3, 4, 5, 7, 8, 10, 11, 13, 15, 16, 17 and 19. Kartagener Syndrome, also known as Primary Ciliary Dyskinesia (PCD), is an autosomal recessive disorder that is characterized by a dynein arm defect. This causes the body's cilia to become immotile.. Individuals who have Kartagener syndrome form a subset of the disorder called primary ciliary dyskinesia. Originally, primary ciliary dyskinesia was known as immotile cilia syndrome. The name, immotile cilia syndrome, is no longer used since the discovery that the cilia are actually not immotile, but rather, abnormal in movement. Individuals who have Kartagener syndrome, basically have primary ciliary dyskinesia, plus partial or complete situs inversus. The situs inversus is what sets Kartagener syndrome apart from primary ciliary dyskinesia.Elena B Willis, MD Resident Physician, Department of Otorhinolaryngology, Albert Einstein College of Medicine, Montefiore Medical Center Elena B Willis, MD is a member of the following medical societies: American Academy of Otolaryngology-Head and Neck Surgery, American Medical Student Association/Foundation, Wilderness Medical SocietyDisclosure: Nothing to disclose.

The defective cilia lining the respiratory tract are unable to clear the airways of secretions and pathogenic bacteria, resulting in mucus retention and chronic or recurrent respiratory tract infection - leading to damage to airway walls. Approximately half of patients with PCD have the full triad of Kartagener's syndrome (KS)[3]. There may also be a link with retinitis pigmentosa and hearing loss[4].The clinical manifestations vary among PCD patients and depend on age. The diagnosis of PCD should be considered in term newborns with respiratory distress or persistent atelectasis/pneumonia with symptoms resembling “wet lung” and no obvious predisposing risk factors. The former presumably reflects the importance of functional cilia in clearing lung liquid shortly after birth.Marthin JK, Petersen N, Skovgaard LT, Nielsen KG. Lung function in patients with primary ciliary dyskinesia: a cross-sectional and 3-decade longitudinal study. Am J Respir Crit Care Med. 2010 Jun 1. 181(11):1262-8. [Medline]. In 1981, Rossman and coworkers [5] coined the term primary ciliary dyskinesia (PCD) because some patients with Kartagener syndrome had cilia that were not immobile but exhibited an uncoordinated and inefficient movement pattern. Current nomenclature classifies all congenital ciliary disorders as primary ciliary dyskinesias in order to differentiate them from acquired types. Kartagener syndrome is part of the larger group of disorders referred to as primary ciliary dyskinesias. Approximately one half of patients with primary ciliary dyskinesia have situs inversus and, thus, are classified as having Kartagener syndrome. Afzelius proposed that normal ciliary beating is necessary for visceral rotation during embryonic development. In patients with primary ciliary dyskinesia, organ rotation occurs as a random event; therefore, half the patients have situs inversus and the other half have normal situs.

In 1994, Lundberg and colleagues reported that children with Kartagener's syndrome (situs inversus, chronic sinusitis, and bronchiectasis) produced very little nasal NO.35 Subsequent studies have demonstrated that nasal NO is extremely low (5% to 15% of normal) in PCD patients,36–39 and hence may be useful for screening for PCD. NO is formed by the nitric oxide synthase (NOS) enzyme system, in the presence of appropriate substrate (l-arginine and oxygen) and cofactors including tetrahydrobiopterin. In normal adults, production of NO from the nose (primarily from paranasal sinuses) is 10- to 50-fold greater than that from the lower airways. Accurate assessment of nasal NO production requires maneuvers for palate closure, breath holding, or intubation to exclude contaminating gases from the lower airway that have much lower NO concentrations. Preschool children cannot cooperate with palate closure or breath-holding maneuvers, therefore assessment of nasal NO production has limited use as a screening test in young children.40 The mechanism for altered nasal NO production in PCD has not been defined. Interestingly, some patients with cystic fibrosis also have low nasal NO, but not as low as in PCD.36

Kartagener Syndrome is genetic, congenital disorder, which affects lungs and also male reproductive organs. In this disease, the cilia, which assisting in transporting mucus in the respiratory tract get affected and may mucous unable to move or move incorrectly. Resulting in this condition cause congestion, infection, and various other complications. In addition, internal organs become completely reversed to mirror image (situs inverses totalis)1,2,8.Zariwala MA, Knowles MR, Omran H; Genetic defects in ciliary structure and function.

The frequency of Kartagener syndrome is 1 case per 32,000 live births. Situs inversus occurs randomly in half the patients with primary ciliary dyskinesia; therefore, for every patient with Kartagener syndrome, another patient has primary ciliary dyskinesia but not situs inversus.This is described as autosomal recessive inherited syndrome. Primary (genetic) defects in the structure and function of sensory and motile cilia result in multiple ciliopathies. A reduction in the number of arms which propel mucus (dynein arms) is a common abnormality but many other structural defects of the cilia have been found. Patients with normal cilia morphology but abnormal mucus propulsion have been detected. In diagnosing the syndrome, therefore, both ciliary structure and motility need to be assessed[1]. Le syndrome de Kartagener aussi appelé syndrome de Siewert est un ensemble de symptômes Lorsqu'une DCP est accompagnée d'un situs inversus , on parle alors du syndrome de Kartagener Chronic bronchitis, recurrent pneumonia, and bronchiectasis are common conditions associated with primary ciliary dyskinesia. Patients presenting with bronchiectasis should be evaluated for Kartagener syndrome. Bronchiectasis usually occurs in the lower lobes in patients with Kartagener syndrome, while patients with cystic fibrosis have bronchiectasis predominantly in the upper lobes.

Елена Костикова о жизни с диагнозом и стереотипах — Wonderzine.. The male infertility in Kartagener syndrome is also caused by abnormal cilia movement. One spermatozoon consists of a head, midpiece, and a tail or flagellum. The tail of a spermatozoon is a long flagellum consisting of a central axoneme. This axoneme enables the movement of the flagellum so that the spermatozoon can propel its way to the fallopian tube and burrow through the egg coat to fertilize the egg. In Kartagener syndrome, these cilia are either immotile, or are not able to move normally to complete the journey to the fallopian tubes, nor may they be able to burrow through the egg coat. This results in male infertility.

Clin Gastroenterol Hepatol. 2006;4:408-15 Infants and older children with PCD may present with atypical asthma that is nonresponsive to treatment or with an increased number of respiratory infections associated with chronic cough and expectoration of mucopurulent sputum over time. The classic presentation of PCD includes chronic rhinosinusitis, recurrent serous otitis media (often requiring multiple interventions, such as repeated courses of antibiotics and placement of myringotomy tubes), and recurrent pneumonia. Nasal polyps and agenesis of the frontal sinuses also are common in childhood. Situs inversus is a useful sign when PCD is being considered, but as described earlier, is present only in approximately 50% of patients with PCD.As stated above, situs inversus is what sets Kartagener syndrome apart from primary ciliary dyskinesia. Complete situs inversus involves reversal of both the abdominal and thoracic organs so that they form a mirror image of normal. In partial situs inversus, the thoracic organs may be reversed, while the abdominal organs are normally positioned, or vice versa. Approximately one in 10,000 adults have situs inversus. Only about 20% of individuals who have complete situs inversus are diagnosed to have Kartagener syndrome. Of those with complete situs inversus who are diagnosed to have Kartagener syndrome, there is only a small risk for associated cardiac defects. Partial situs inversus may occur in individuals who have Kartagener syndrome as well. Partial situs inversus has a higher association with other abnormalities, including polysplenia or asplenia (extra or absent spleen) and cardiac defects.

Book with title Kartagener syndrome on a table Camner and coworkers [2] first suggested ciliary dyskinesia as the cause of Kartagener syndrome in 1975. They described two patients with Kartagener syndrome who had immotile cilia and immotile spermatozoa. These patients had poor mucociliary clearance because the cilia that lined their upper airways were not functioning.Cylindrical or saccular bronchiectasis may occur, even in childhood, usually affecting the middle and lower lobes and the lingula. Patients with bronchiectasis have auscultatory crackles and may have wheezes that mimic asthma. Common findings on chest x-ray and computed tomography (CT) scan are a moderate degree of hyperinflation, peribronchial thickening, atelectasis, and bronchiectasis. Digital clubbing is uncommon in patients younger than 18 years old.

Primary Ciliary Dyskinesia

Литература. Kumar S., Rao K. Waardenburg syndrome: A rare genetic disorder, a report of two cases The genetic mutation leads to the inability of cilia movement (immotile) or incorrect movement (dysmotile) of cilia. Yet now different genes  are identified to cause Kartagener syndrome, among them chromosome 9, 5 and 7 cause morphologic or functional abnormality of cilia. Meaning of Kartagener syndrome medical term. What does Kartagener syndrome mean? Kartagener syndrome - complete situs inversus associated with bronchiectasis and chronic sinusitis Kartagener syndrome occurs in approximately one in 32,000 live births, which is half the incidence of primary ciliary dyskinesia (one in 16,000 live births). Kartagener syndrome is not found more commonly in any particular sex, ethnic background or geographic region. Males, however, may be diagnosed more often than females because of infertility investigation.Kartagener syndrome is caused by abnormalities of the cilia that line the respiratory tract and also form the flagella of sperm. Cilia are tiny hair-like structures that contain a bundle of small parallel tubes that form a central core. This core is called the axoneme. Ciliary movement is accomplished by the bending of the axoneme. One of the most important associated structures that enable ciliary movement to occur are sets of tiny arms that project from each tubule. These tiny arms are called dynein arms.

Treatment with antibiotics, physiotherapy and appropriate surgical intervention has improved the prognosis in these patients and, in many cases, lifespan may be normal. Early diagnosis is important. Once bronchiectasis is established, prognosis worsens significantly.Mierau GW, Agostini R, Beals TF, Carlén B, Dardick I, Henderson DW, et al. The role of electron microscopy in evaluating ciliary dysfunction: report of a workshop. Ultrastruct Pathol. 1992 Jan-Apr. 16(1-2):245-54. [Medline]. The cilium is anchored at its base by cytoplasmic microtubules and a basal body comprised of a basal foot and rootlet. The orientation of the basal foot indicates the direction of the effective cilial stroke. Just above the base, the cilium is composed of microtubular triplets (previously doublets) without associated structures, but at the tip, only the B subunits remain.Poor clearance of secretions and recurrent infection result in bronchiectasis and progressive lung disease (Fig. 4.19). Diagnostic evaluation for primary ciliary dyskinesia includes direct examination of ciliary movement and ultrastructural examination of cilia. Light microscopic examination of unstained wet preparations using fresh ciliary brushings and/or biopsies may be used as a screening tool. Lack of coordinated and rhythmic ciliary movement may reflect primary ciliary dyskinesia but may also be secondary to other factors, including the presence of squamous metaplasia or inflammation. Repeat biopsy after resolution of inflammation may be necessary in this circumstance. Ultrastructural analysis of cilia oriented in cross-section is used to detect variable structural abnormalities in the ciliary apparatus, including absent or short dynein arms, lack of radial spokes, compound cilia or abnormal ciliary orientation, and other microtubular abnormalities (Fig. 4.20).The chance for an affected male and his unaffected partner to have a child who has Kartagener syndrome is small. If the disease incidence is one in 32,000, then the chance for the unaffected woman to be a carrier of Kartagener syndrome is approximately one in 100 and the chance for having an affected child would be expected to be approximately one in 200 (0.5%). However, all children of affected males or females will be carriers for Kartagener syndrome.

The most common clinical expression of Kartagener syndrome in adults includes chronic upper and lower airway disease presenting as sinusitis and bronchiectasis. Clubbing of the digits (fingers) may occur as the result of chronic hypoxia (lack of oxygen) from bronchiectasis. In males of reproductive age, male infertility is almost universal. In females who have Kartagener syndrome, infertility is not usually a characteristic. This suggests that the egg transport down the fallopian tube is associated more with muscle contractions than with ciliary movement.

Other features include digital clubbing, male infertility, and diminished female fertility. Primary ciliary dyskinesia has been associated with esophageal problems and congenital cardiac abnormalities.The symptoms in adolescents and adults are similar to the symptoms in older children, but otitis media seems to be less prominent. Infertility is common in affected adults, especially in men owing to immotile sperm—a modified cilium. Fatigue and headaches are common complaints and may be related to chronic sinusitis, although the headaches may persist even during infection-free periods.Francisco Talavera, PharmD, PhD Adjunct Assistant Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Received salary from Medscape for employment. for: Medscape.Sinonasal disease in primary ciliary dyskinesia has been poorly studied; however, these patients often have recurrent chronic sinusitis with sinus pressure headaches in the maxillary and periorbital regions. Sinus radiographs (which largely have been supplanted by CT scans) typically demonstrate mucosal thickening, opacified sinus cavities, and aplastic or hypoplastic frontal and/or sphenoid sinuses. [17] Symptoms usually improve with antibiotic therapy but have a propensity for rapid recurrence. It appears that patients with chronic rhinosinusitis (CRS) may benefit from long-term macrolide therapy and endoscopic sinus surgery (ESS) in recalcitrant disease. Therapies targeted at improving mucociliary clearance have not been tested specifically in primary ciliary dyskinesia. [18] It has been shown that up to 59% of patients have recurring episodes of sinusitis and 69% of these patients require surgical intervention. [19]
