High Inborn Errors of Immunity Risk in Patients with Granuloma.

OBJECTIVE: Granuloma etiology includes infections, vasculitis, chemicals, malignancies, lymphoproliferative disorders, and immunological diseases. We hypothesized that patients with granuloma have an underlying primary immunodeficiency disease (PIDD). PATIENTS AND METHODS: We retrospectively enrolled 82 patients with immunological evaluation among 294 biopsy-proven granuloma patients (0- to 20-year-old). At the same time frame, we followed up with 1910 patients in the same age group. RESULTS: Out of 82 patients, male/female ratio was 45/37. Median age at symptom onset was 5 years (28 days-17.4 years), age of granuloma at diagnosis was 8.6 years (36 days-19.4 years). Common symptoms at disease onset were fever (23.2%), lymphadenopathy (19.6%), abdominal pain (12.2%), and cough (12.2%). Granuloma was frequent in lymph nodes (26.8%), skin (19.5%), lung (13.4%), and bone (11%). Common infectious agents isolated were Mycobacterium spp. (23.2%) and EBV (4.9%). We document PIDD in 76.8% (63/82) of patients. 49.4% (40/81) of immunologically evaluated granuloma patients had hypogammaglobulinemia. Granuloma rate in pediatric PIDD was 3.3%(63/1910). Patients with multiple granulomas (n = 16) had a PIDD diagnosis. Lung involvement was three times more in PIDD. Brain involvement was only seen in PIDD. Fibroadipose tissue and liver involvement were more frequent in patients without documented PIDD and patients whose evaluation was not completed. The mortality rate in PIDD with granuloma was 15.9%, whereas there was no mortality in patients without PIDD. CONCLUSION: As documented here, even in a university hospital, the immunologic evaluation ratio is about one-third. We showed high PIDD frequency in children with granuloma, and higher mortality in PIDD with granuloma. Thus, an immunologic evaluation performed meticulously by immunologists is a must for accurate diagnosis and decision of individualized therapeutic options.

[Investigation of role of anaerobic bacteria in cystic fibrosis patients]. / Kistik fibrozisli hastalarda anaerop bakterilerin rolünün arastirilmasi.

INTRODUCTION: Repetitive pulmonary infections are the main cause of morbidity and mortality in cystic fibrosis (CF) patients. In recent years, non-culture dependent metagenomic studies showed complex dynamics of the pulmonary environment of CF patients and pointed out the importance of anaerobic bacteria. Molecular-based studies indicate that anaerobic bacteria can be found more than aerobic or facultative anaerobic bacteria in CF lung environment. However, limited number of studies are far away to clarify the importance of anaerobic bacteria in CF pulmonary disease. MATERIALS AND METHODS: The aim of this study was to evaluate the role of anaerobic bacteria in CF patients admitted to Hacettepe University, Pediatric Respiratory Diseases Department, by using quantitative culture method for both aerobic and anaerobic bacteria. Anaerobic bacteria were identified by conventional and semi-automated methods. Antibiotic susceptibilities were performed by agar dilution method. RESULT: Seventy-seven anaerobic bacteria were isolated from 35 (81.4%) of 43 patients. The total count of anaerobes and facultative bacteria (mean 16 x 106), was higher than aerobes and facultative bacteria (mean 14.1 x 106). If anaerobe culture were not performed merely 63.65% of all species could be obtained. In patients whose samples yielded intermediate or high numbers of PMNLs, significantly more obligate anaerobic bacteria were isolated (p= 0.046). Patients older than 18 years were colonized with higher number of anaerobic bacteria. Susceptibilities of 72 isolates out of 77, against ampicillin, sulbactam-ampicillin, piperacillin, piperacillin-tazobactam, moxifloxacin, metronidazole, imipenem, and clindamycin were also evaluated. Clindamycin was found to be the least effective antibiotic among all. None of the isolates was resistant to imipenem. CONCLUSIONS: This is the first study to show the role and importance of anaerobic bacteria in CF patients in our country. The resistance rates in anaerobic bacteria isolated from CF patients is concerning. Therefore, intermittent anaerobic culture and follow-up of resistance rates will be helpful in the follow-up of these patients.

Aerobic exercise training in Kartagener's syndrome: case report.

Kartagener's syndrome is a rare, autosomal recessive inherited disease, which is characterized by a triad of chronic sinusitis, bronchiectasis, and situs inversus. In this report, we aimed to represent the effect of aerobic exercise training in addition to chest physiotherapy in an outpatient with Kartagener's syndrome. An 18-year-old female diagnosed with Kartagener's syndrome applied with the complaints of productive cough and dyspnea with exertion and attended pulmonary rehabilitation program comprising exercise training in addition to standard treatment. Aerobic exercise training was performed three times weekly at 80% of the peak heart rate, for 8 weeks as supervised sessions. Respiratory physiotherapy and postural exercises were taught to the patient to be performed at home each day of the week. Before and after pulmonary rehabilitation program, incremental shuttle walk test (ISWT) was performed; dyspnea and fatigue were assessed using Borg Scale. Pulmonary function test was evaluated using spirometer. The patient wore activity monitor for 7 consecutive days before and after training. After pulmonary rehabilitation program, 90-m increase in ISWT was observed. We recommend exercise training in patients with Kartagener's syndrome to increase exercise capacity. Further randomized control trial is needed to clarify the effects.

Chronic necrotizing pulmonary aspergillosis in an immunocompetent patient after the surgery of hydatid cyst.

Chronic necrotizing pulmonary aspergillosis (CNPA) is a condition caused by the ubiquitous fungus Aspergillus fumigatus in non-immunocompromised individuals. Numerous underlying conditions have been associated with CNPA. Tuberculosis, non-tuberculous mycobacterial infection and allergic bronchopulmonary aspergillosis (ABPA) remain the predominant risk factors for development of CNPA. Development of CNPA in echinococcal cyst cavities is very rare and the optimal therapeutic regimen and treatment duration have not been established. Here, we present a case of CNPA developed six years after the cystectomy operation of hydatid cyst and treated with voriconazole successfully.

Paper #3: Can TGR change the natural history of pulmonary functions in EOS? Is Radiological Straightness Correlated with Normal Lung Development?

Even though traditional growing rod (TGR) patients score lower in exercise tolerance and spirometry compared to age-matched controls, their pulmonary functions are similar to those of instrumented adolescent idiopathic scoliosis (AIS) patients.
