ABSTRACT
BACKGROUND AND AIM: Sarcoidosis is a granulomatous disorder of unknown etiology characterized by the existence of non-caseating granulomatous inflammation. Diagnosis can be challenging due to the presence of comprehensive clinical, laboratory, and radiologic manifestations. We have evaluated the diagnostic yield of the Kveim test and compared this test with the other conventional laboratory modalities. Our aim was to reach the highest level of diagnostic confidence acknowledging the absolute uncertainty in diagnosis with the current diagnostic enterprises. METHODS: Medical records of 300 sarcoidosis patients were reviewed. Patients were classified into two categories as the conventional laboratory and the Kveim test group to compare the diagnostic yield. RESULTS: Sensitivity of the Kveim test was 76.4% while the conventional laboratory tests provided a 64% diagnostic yield. The conventional tests had a low diagnostic rate in the early disease stages. Kveim test revealed a high yield diagnosis for all stages of sarcoidosis. Integrated assessment of the two modalities reached a 96.8% sensitivity and a 94,6% specificity. CONCLUSIONS: Conventional laboratory modalities were useful for the assessment of disease activity and identification of organ involvement. Kveim test revealed a significant diagnostic yield for all stages of sarcoidosis. The lowest output was achieved in stage IV patients due to the waning of active granulomatous inflammation. The highest diagnostic sensitivity was obtained by an integrated analysis of the conventional laboratory and the Kveim test results for all aspects of sarcoidosis.
ABSTRACT
Sarcoidosis is a chronic granulomatous disease of unknown etiology. The disease most commonly involves the lungs and the mediastinal lymph nodes while extrapulmonary organs such as the skin, eye, liver or spleen may also be comprised. Many imaging modalities have been used for the clinical evaluation of sarcoidosis patients but all have been found to have certain drawbacks for a reliable identification assessment due to the equivocal diagnostic results. This case series was designed to determine the clinical trenchancy of simultaneous 68Ga citrate PET/CT [Positron emission tomography with 68Ga citrate (68Ga citrate PET/CT)] and 18F-FDG PET/CT [Positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-D-glucose integrated with computed tomography (18F-FDG PET/CT)] imaging in sarcoidosis patients. The main goal of the study was to evaluate sarcoidosis with respect to disease activity and organ involvement. A total of eight sarcoidosis patients with a comorbid disease suspicion were included in the study. Conventional clinical parameters used for the diagnosis and the activity of sarcoidosis including CT [Computed tomography (CT)] were compared with the 68Ga-citrate PET/CT findings. Concurrent 18F-FDG PET/CT was performed to verify the granulomatous inflammation of sarcoidosis and to determine coexisting malignant or other inflammatory diseases. Our study results revealed that 68Ga citrate PET/CT imaging appears to be highly useful for the diagnosis, activity assessment and extrapulmonary organ involvement in sarcoidosis. Another crucial finding was the detection of extrapulmonary organ disease that are exceptionally involved, almost inaccessible by biopsy and that could not be otherwise displayed by other conventional imaging modalities. The third hallmark was the identification of a clinically asymptomatic and occult malignancy accompanying sarcoidosis that would not be revealed in any way if synchronous 18FDG PET/CT had not been performed. Simultaneous application of 68Ga citrate and 18FDG PET/CT may provide extremely useful data for the clinical evaluation of sarcoidosis patients in terms of the primary disease diagnosis, activity state, extrapulmonary organ involvement unachievable for biopsy and the clinically occult malignant disorders.

Sarcoidosis is a multisystem granulomatous inflammatory disorder frequently affecting the lungs, but also the liver, along with cirrhosis and portal hypertension occurring in less than 1% of the patients. A 56-year-old female presented with dyspnea, abdominal and leg swelling. Physical examination revealed finger clubbing, ascites and pretibial edema. Chest CT revealed diffuse micronodular opacities in both lungs without any enlarged thoracic lymph nodes. PFTs and DLCO/VA were moderately decreased. Transbronchial biopsy revealed non-caseified granulomas compatible with sarcoidosis. Serologic markers for infectious and autoimmune hepatitis were negative. Liver biopsy showed non-caseating granulomas, severe hepatitis and fibrosis. Stool, urinary analysis and antibodies for Schistosoma infection were negative. Final diagnosis was cirrhosis associated with stage III sarcoidosis. We report a case of sarcoidosis complicated by cirrhosis and portal hypertension with finger clubbing. Clinicians should bear in mind that cirrhosis, portal hypertension and clubbing may arise as the initial manifestations of sarcoidosis.

Sarcoidosis is a multisystemic disease that may lead to neurologic complications in 10% of the patients. Carpal tunnel syndrome is very rare in sarcoidosis. We present two identical twin sarcoidosis patients with carpal tunnel syndrome. A number of factors may cause carpal tunnel syndrome like wrist anatomy, occupation, diabetes, rheumatoid arthritis, pregnancy and renal failure. Although the above factors do not directly cause carpal tunnel syndrome, they may increase your chances of developing or aggravate median nerve damage as it is in sarcoidosis. Sarcoidosis relevant neuropathy and granulomas may be the primary mechanism of sarcoidosis associated carpal tunnel syndrome. Although rare, carpal tunnel syndrome may be a feature of sarcoidosis that may lead to irreversible damage in cases of delayed diagnosis. The presence of this syndrome in identical twin patients may shed light into the pathogenesis and the genetic transmission of sarcoidosis with the associated carpal tunnel syndrome.

The main objective of this study was to evaluate the influence of muscle involvement on the clinical features, prognostic outcome, extrapulmonary organ, and endobronchial involvement in sarcoidosis patients. The second aim was to assess the diagnostic yield of muscle biopsy for the histopathologic identification of sarcoidosis. Fifty sarcoidosis patients participated in the study. The patients were classified into two groups according to the histopathologic presence of non-caseating granulomatous inflammatory pattern of the muscle biopsy samples and were evaluated retrospectively in regard to clinical features, prognosis, extrapulmonary, and endobronchial disease involvement. Pathologic examination of the muscle biopsy samples revealed non-caseating granulomas in eighteen and myositis in seven patients compatible with sarcoidosis. The diagnostic yield of muscle biopsy for demonstrating non-caseating granulomatous inflammation was fifty percent. Patients with muscle sarcoidosis showed a worse prognosis and a more severe extrapulmonary organ involvement than the patients without muscle disease. Muscle biopsy was not statistically significant to delineate diffuse endobronchial involvement while it was suggestive for endobronchial disease clinically. The results of our study reveal that muscle biopsy appears to be a useful diagnostic tool along with its safety and easy clinical applicability. It is a rewarding utility to predict the prognostic outcome and extrapulmonary involvement in sarcoidosis patients. Positive biopsy on the other hand confirms the identification of sarcoidosis in patients with single organ involvement carrying an equivocal diagnostic clinical pattern. Muscle biopsy may be considered as the initial step for the final diagnosis of sarcoidosis in such cases.
ABSTRACT
Patients with sarcoidosis usually have a benign course and a favourable prognosis. Although spontaneous remission is common, a progressive disease with a severe prognosis occurs in a small but significant number of patients. The aim of this study was to evaluate the potential significance of HLA antigens as a clinical marker on the outcome of sarcoidosis patients. We conducted a retrospective cohort study for HLA class I and II allels in 74 sarcoidosis patients and 72 healthy transplant donors. Bronchoscopy and bronchial biopsies were performed in each patient. Two or more positive bronchial biopsy samples revealing granulomatous inflammation was defined as diffuse while one positive biopsy sample was considered as limited endobronchial disease. Three or more extrapulmonary organ involvement was denoted as severe extrapulmonary disease. The patients were followed-up at least for eight years. Incidence of progressive disease was significantly high in patients with positive HLA-DRB1*07, DRB1*14 (p<0.05) and DRB1*15 (p <0.001) allels. HLA-DRB1*14 and DRB1*15 were associated with severe extrapulmonary organ involvement (p<0.001). HLA-DRB1 *14 (p<0.05) and DRB1*15 (p<0.001) were significantly more frequent in patients with diffuse endobronchial involvement. Incidence of familial disease was 14.8% with a 6.7% identical HLA typing. Presence of HLA class I and II allels may influence the severity and prognosis of sarcoidosis significantly. Apart from defining genetic susceptibility, HLA class I and class II allels appear to be relevant and crucial markers for the to predict the clinical outcome of sarcoidosis. Distinct heterogenity of sarcoidosis may arise from the particular presence of different allels in invidual patients.

Sarcoidosis is a systemic disease characterized by noncasefied granulomas in various organs. Incidence of splenic disease is variable and is reported to occur in 6.7 to 77 percent of the patients. Firm data establishing the clinical features and the association of splenic involvement with prognosis in sarcoidosis is scant. The aim of our study was to investigate the clinical features and the consequence of splenic involvement on the prognostic outcome of sarcoidosis patients. We evaluated the clinical and laboratory findings in 82 sarcoidosis patients. Forty-two patients with splenic involvement were compared to 48 sarcoidosis patients without splenic disease in regard to laboratory findings, endobronchial disease, extrapulmonary organ involvement, and prognosis. Lung biopsy sample was considered positive if it demonstrated noncaseating granulomas with negative fungal and mycobacterial cultures. Splenic sarcoidosis was identified by ultrasound or computed tomography and was designated as limited, diffuse or without splenic involvement. Extrapulmonary organ sarcoidosis was classified as extensive and limited. Endobronchial disease was categorized as limited or diffuse involvement. The most commonly comprised organ was lung in 95% of the cases followed by lymph nodes, skin, eye, spleen and liver in the order of frequency. Splenic disease was diffuse in 22 patients. Of these patients, 14 had extensive extrapulmonary organ involvement while 16 had diffuse endobronchial disease. There was no significant difference between the three groups for FEV1, FVC, TLC, DLCO/VA, serum and 24h urinary calcium levels. Serum ACE was higher in patients with diffuse splenic involvement (p<0.001). Incidence of persistent chronic disease was significantly higher (p<0.001) in patients with diffuse splenic sarcoidosis. Extensive extrapulmonary organ involvement and diffuse endobronchial disease were more common (p<0.001) in this group. Extensive extrapulmonary organ involvement and diffuse endobronchial disease were more frequent in patients with diffuse splenic sarcoidosis. Patients with diffuse splenic granulomas had a worse prognosis than the patients without splenic involvement or patients with limited splenic disease. Diffuse splenic involvement emerges to be a significant risk factor for persistent chronic sarcoidosis. Extensive granuloma burden in an organ may be the decisive clinical marker for the prognostic outcome of sarcoidosis patients.

BACKGROUND: Sarcoidosis is a systemic disease characterized by the formation of noncaseating granulomas in various tissues. Cutaneous involvement occurs in 20 to 35 percent of the patients and may be the initial manifestation of the disease. Our study was performed to discriminate the clinical, laboratory, and prognostic differences between patients with specific and nonspecific cutaneous involvement. The second aim was to asses the diagnostic usefulness of punch biopsy in sarcoidosis. METHODS: The clinical, laboratory, pathological features, and skin biopsy results of 120 patients with cutaneous sarcoidosis were evaluated. The patients fulfilled clinical, radiologic or both features of sarcoidosis supported by the histopathologic evidence of noncaseating granulomas.Skin involvement was the initial finding in 30% of the patients. Erythema nodosum and lupus pernio were the most common skin lesions. Almost all of the patients with LP were either stage 0 or 1. Respiratory symptoms occurred in 72.2% of the patients with specific skin involvement. BronchoalveolarLavage (BAL) lymphocytosis, high ratio of CD4/CD8 and elevated serum Angiotensin Converting Enzyme (ACE) were more frequent in patients with specific cutaneous lesions. The frequency of progressive disease was significantly higher in this group. Punch skin biopsy was diagnostic in 81.6% of the patients with a complication rate of 4%. CONCLUSIONS: Specific cutaneous lesions along with BAL lymphocytosis, high CD4/CD8 ratio and elevated serum ACE levels may be predictors of progressive disease in sarcoidosis. Punch biopsy is a simple technique with a high diagnostic yield and a low complication rate for cutaneous sarcoidosis.
ABSTRACT
OBJECTIVE: Acute myeloid leukemia (AML) is the most common acute leukemia in adults. Pulmonary are among the most common causes of mortality in AML. This single-center retrospective study aimed to evaluate the relationship between radiological findings of pulmonary at presentation and post chemotherapy on prognosis and clinical outcome in a group of AML patients. MATERIAL AND METHODS: The study included 278 AML patients. Clinical and radiological findings, laboratory findings, and microbiological culture results were evaluated. Pulmonary complications at presentation and post chemotherapy were compared. RESULTS: Pulmonary complications were observed in 53 of the patients (19%). Mean age of the patients with and without pulmonary complications was 43.1 ± 15.2 years and 38.8 ± 16.3 years, respectively (P < 0.001). Pulmonary complications were not correlated with gender, AML subtype, or the serum lactate dehydrogenase (LDH) level. The most common cause of pulmonary complications was infection. Pulmonary complications were observed in 29% and 71% of the patients at presentation and post chemotherapy, respectively. CONCLUSION: Pulmonary complications were observed more frequently at presentation in neutropenic AML patients of advanced age. The mortality rate was higher among the AML patients that had pulmonary complications at presentation.
ABSTRACT
OBJECTIVES: To determine the possible role of oxidants and antioxidants in the pathogenesis of in laryngeal squamous cell carcinoma. DESIGN AND SETTING: Our study involved patients with newly diagnosed laryngeal cancer (n = 29) and same age- and sex-matched healthy individuals (n = 21). Serum malondialdehyde (MDA) and paraoxonase (PON1) levels were measured by colorimetric methods and 8-hydroxy-2'-deoxyguanosine (8-OH-dG) was measured using enzyme-linked immunosorbent assay in fasting blood samples of participants. RESULTS: The levels of 8-OH-dG (control, 4.61 ± 1.27 ng/mL; patient, 11.70 ± 2.44 ng/mL; P < 0.001) and MDA (control, 4.16 ± 1.02 nmol/mL; patient, 8.74 ± 1.65 nmol/mL; P < 0.001) were significantly higher, and those of PON1 (control, 170.86 ± 72.46 U/mL; patient, 80.44 ± 29.81 U/mL; P < 0.001) were significantly lower in patients. There were no statistically significant differences in the 8-OH-dG, MDA levels, and PON1 activity in relation to T (tumor) staging of differentiation and different smoking/drinking status. There was a statistically significant difference in MDA levels (10.24 ± 0.64 nmol/mL) only in stage II laryngeal cancer. There were a statistically significant positive correlation between serum MDA and 8-OH-dG (r = 0.887, P < 0.001), a statistically significant negative correlation between serum MDA and serum PON1 (r = -0.477, P < 0.01), and a statistically significant negative correlation between serum 8-OH-dG and serum PON1 in patients (r = -0.420, P < 0.05). CONCLUSIONS: We conclude that, in patients with laryngeal squamous cell carcinoma, the oxidant/antioxidant balance was impaired in favor of lipid peroxidation and DNA damage.

A peripheral lymph node (PLN) 1 cm or greater was found in 79 of 546 sarcoidosis patients (14.5%) between 1972 and 2005. Seventy-two of the 79 sarcoidosis patients had a lymph node biopsy performed. Sixty-seven of these biopsy specimens were histologically diagnosed as sarcoidosis, whereas five patients had a reactive adenopathy. For patients with histological diagnosis of sarcoidosis, localizations of the biopsies were as follows: cervical (n=21), supraclavicular (n=20), inguinal (n=11), axillary (n=8), epitrochlear (n=5) and submandibular (n=2). At the time of biopsy, 12 patients had stage 0 disease, 37 patients had stage I disease, 14 patients had stage II disease and four patients had stage III disease. Skin involvement (16.4%) was the most frequently observed type of organ involvement in patients who had enlarged PLNs due to sarcoidosis. In the presence of an enlarged PLN in sarcoidosis, biopsy had a greater diagnostic value compared with other methods, as well as having a relatively low cost (approximately US$120) in Turkey. No procedure-related complications were observed. In conclusion, it is recommended that PLNs be thoroughly examined when sarcoidosis is suspected. If an enlarged PLN is found, biopsy should be routinely performed because it is an easy, convenient and practical method, with a low complication risk and a high sensitivity.

BACKGROUND: Sarcoidosis is a systemic granulomatous disorder associated with high CD4+cell activity, without any detectable pathogen. Clustering in families occurs, and the existence of a genetic predisposition to sarcoidosis is widely accepted. There are differences among different ethnic groups. METHODS: We studied HLA polymorphisms in 64 Turkish patients with biopsy proven sarcoidosis. The control group was taken of 160 donor candidates of kidney transplantation within the same period. RESULTS: Fifty-one patients were female, and 13 were male. The mean age was 39 +/- 6.1 years. Frequency of HLA A2, A9, A24 (9), A25, A69 (28), B12, B22, B38, B49 (21), DR4, and DR14 antigens were significantly higher, and frequencies of HLA B7 and DR7 were significantly less in sarcoidosis patients. Clustering in some families were also noted in our study. CONCLUSIONS: This study implies a genetic predisposition to sarcoidosis in the Turkish population. Clustering in some families should be kept in mind.

BACKGROUND: Clinical manifestations and prognosis of sarcoidosis are heterogenous and the prevalence varies depending on the country, area and race evaluated. Also the organs involved and courses of the disease differ greatly between countries, areas, races and individuals. AIMS: To investigate the sociodemographic characteristics, clinical presentation and symptoms and to determine the severity and prognosis of sarcoidosis in Turkey as a referral center. METHODS: Between January and July 2003 we retrospectively evaluated the outcome of the patients with sarcoidosis whose first clinical visits were between 1965 and 2003 in the multidisciplinary referral setting RS at Cerrahpasa Medical Faculty of the University of Istanbul. Data collected about each patient included sociodemographic characteristics, clinical presentation, symptoms, date of diagnosis, date and age of onset, method and stage of disease at the date of diagnosis and at the date of last evaluation; the mortality and survival rate were calculated. One hundred and sixty six consecutive patients whose first clinical visits were between 1965 and 2003 in the multidisciplinary RS at Cerrahpasa Medical Faculty were enrolled. We contacted every patient in our cohort by telephone calls or home visits. All those contacted were called back to outpatient clinic for a formal evaluation between June and September 2003. A formal physical examination and thorax radiography were performed in patients who came to the hospital. Their radiological stage, signs, symptoms and associated extrapulmonary manifestations were recorded. RESULTS: At the initial presentation, the mean age of diagnosis was 40.3 years. The 31-40 age group is the group with the highest number of patients. Coughing was the most frequent symptom and erythema nodosum was the most frequent sign in both sexes. Thirty eight percent of patients had extrathoracic involvement. The most frequent extrapulmonary site of involvement was skin. The mortality rate was 11.6% (10.8% in females and 13% in males). Comorbidity was 3% (5 females, 1 male). Females, youngs and patients without extrathoracic involvement had higher survival rates. CONCLUSION: Clinical characteristics, course and prognosis of sarcoidosis vary in different studies. The results may vary accordingly to ethnic, geographic, social and economic conditions.

PRINCIPLES AND METHODS: Upper respiratory tract (URT) involvement is rare in sarcoidosis. In this descriptive study, we retrospectively evaluated the clinical and demographic features of 12 (2.19%) patients with URT involvement out of the 546 sarcoidosis patients with follow-up visits at our center within the last 40-year period. RESULTS: Out of the 546 patients, 12 (2.19%) had upper respiratory tract involvement, 5 (0.91%) had laryngeal involvement, 4 (0.73%) had sinonasal tract involvement, 2 (0.36) patients had salivary gland involvement, and 1 patient had tonsillary involvement. The number of stage 0 subjects among other sarcoidosis patients was significantly lower than that among those with URT involvement. CONCLUSIONS: URT involvement is rarely diagnosed in patients with systemic sarcoidosis. The most common site for URT involvement among the Turkish population is the larynx, followed by the sinonasal tract. EBM RATING: C-4.

OBJECTIVE: To compare the features of sarcoidosis in children to those of adults. In spite of the fact that sarcoidosis is a disease frequently seen in adults of 30-40 years, pediatric cases have rarely been reported. METHODS: The authors evaluated 17 (3.3%, 12 females, 5 males) of the 516 patients of sarcoidosis, aged 16 yr and diagnosed within a 36-year period. RESULTS: When the features of sarcoidosis subjects diagnosed during the childhood period were compared to those of subjects >16 years of age, it was seen that patients with advanced stage of the disease were more in the first group (41.2% vs 18%, p=0.02). In addition, children had more frequent extrapulmonary (64.7% vs 40.3%) and lacrimal gland involvement (p values, respectively, 0.044 and 0.003). CONCLUSION: When clinical data are relevant, sarcoidosis should be borne in mind. A child with sarcoidosis has more frequent pulmonary parenchymal and extrapulmonary involvement than in adults.

OBJECTIVES: Although sarcoidosis is classically defined to be a disease of young adults, it might also be seen at older ages. There are very few clinical studies which focus on the features of patients diagnosed at older ages. In this study, we tried to determine the frequency of patients diagnosed at or above 50 years of age and to compare the clinical and demographic features of these subjects with other sarcoidosis patients. METHODS: We evaluated the general clinical features of sarcoidosis patients more than 50 years of age who were diagnosed at our center within a 36-year period. We also compared the clinical features of older sarcoidosis patients with the features of other patients. RESULTS: Of 579 sarcoidosis patients being followed up at our center, 102 (17.7%) were older than 50 years of age at the time of initial diagnosis. The female to male ratio in this group was higher than the ratio in other sarcoidosis patients (3.43 versus 1.85, P = 0.015). When the features of older patients were compared with other sarcoidosis patients, extrapulmonary involvement was observed to be more common in this group (P < 0.001). By contrast, arthritis or arthralgia (P < 0.001), clinical presentation in the form of Löfgren syndrome (P < 0.001), erythema nodosum (P < 0.001), and uveitis (P = 0.006) were less frequent. CONCLUSIONS: Although generally presenting as a disease of the young, in many subjects sarcoidosis is diagnosed at older ages, and this study indicates that the clinical features of sarcoidosis in older subjects differ from those found among younger patients.

The incidence of bone cysts in sarcoidosis, a multisystemic disease, varies in different series, and these cysts are generally asymptomatic. We evaluated bone cysts in 516 sarcoidosis patients with available hand X-rays and in 200 patients with foot X-rays. Bone cysts were present in 21 cases (19 females, two males). The cysts were localized in phalanges of the hand in all cases, in feet in five cases, and in nasal bone in one. Six patients with bone cysts also had lupus pernio. Among those with cystic bone lesions, females were more frequent; extrapulmonary and skin involvement and lupus pernio were significantly more common. We diagnosed cystic bone lesions in 3.6% of our sarcoidosis patients and conclude that cysts were more frequent in females and in patients with lupus pernio.

BACKGROUND: The therapeutic response to endobronchial tuberculosis is usually evaluated by bronchoscopy. Currently, there are no published studies investigating the use of computed tomography for the evaluation of therapeutic response in endobronchial tuberculosis. OBJECTIVE: A retrospective study was performed to evaluate the bronchoscopic and computed tomographic features of endobronchial tuberculosis before and after treatment. The aim of this study was to investigate the usefulness of computed tomography for the assessment of treatment. METHODS: The clinical, pathological and bronchoscopic features of endobronchial tuberculosis were evaluated in 55 patients. The age range of the patients was 21 to 52 years. Computed tomography and bronchoscopy were performed before and after treatment. RESULTS: Diagnosis of tuberculosis was confirmed by culture and histopathological examination. Bronchoscopic examination revealed 89 endobronchial lesions of various types in 55 patients. The exudative type was the most common. Follow-up bronchoscopy revealed that exudative-, ulcerative- and granular-type lesions healed completely. Computed tomography performed after treatment correlated well with the follow-up bronchoscopic findings. CONCLUSION: The results suggest that follow-up computed tomography is useful for the evaluation of therapeutic response and complications associated with endobronchial tuberculosis, and may replace bronchoscopy.
