ABSTRACT
INTRODUCTION: Chronic kidney disease (CKD) is a potentially life-threatening condition leading to various psychosocial problems associated with different treatment modalities in addition to their medical advantages and disadvantages. The aim of this study was to evaluate the psychiatric morbidity in children with CKD in terms of different treatment modalities in comparison to healthy peers. In addition, parental attitudes and psychiatric symptoms in this group of mothers were examined. POPULATION AND METHODS: A matched cohort study including 66 children with CKD (21 renal transplantation, 27 dialysis, 18 conservative treatment) and 37 healthy age- and sex-matched controls were evaluated. Children filled out the Children's Depression Inventory, the State-Trait Anxiety Inventory, and the Parental Attitude Scale, and the mothers filled out the Symptom Checklist-90-R. The Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version was used for psychiatric diagnosis. RESULTS: The overall depression scores in children and the mothers' overall symptom severity index were significantly higher in the CKD group: 40.9% of children in the CKD group were diagnosed with a psychiatric disorder, while the corresponding figure for the control group was 16.2%. The in-group comparison of the CKD group failed to detect any significant difference between the three treatment modalities. CONCLUSION: The results support the findings of research showing that CKD has high psychiatric morbidity. It is important to include psychosocial and psychiatric assessments in the evaluation processes of different treatment modalities in CKD.

OBJECTIVE: Immunoglobulin A vasculitis/Henoch-Schönlein purpura (IgAV/HSP) is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA. It is the most common primary systemic vasculitis of childhood and is much less common in adults. Our aim was to investigate the differences and similarities between adult and paediatric patients with IgAV/HSP. METHOD: We retrospectively evaluated the medical records of 35 adult and 159 paediatric (Ë 18 years old) patients with a clinical diagnosis of IgAV/HSP who were seen at the Departments of Rheumatology and Pediatric Rheumatology, Hacettepe University, Ankara, Turkey. The paediatric and adult patients were classified with IgAV/HSP according to the Ankara 2008 and American College of Rheumatology 1990 criteria, respectively. RESULTS: Upper respiratory tract infection was a common predisposing factor for both adults (34.3%) and children (21.4%). Creatinine and C-reactive protein were higher; and skin biopsy, hypertension, renal involvement, haematuria, proteinuria, and renal insufficiency at diagnosis were more frequent in adults than in children. Thrombocyte count was higher in children than in adults. Follow-up without treatment and complete recovery were more frequent in children, while persistent haematuria, chronic renal failure, relapse, and the use of corticosteroids/azathioprine were more frequent in adults. The only independent predictive factor for relapse was persistent haematuria. CONCLUSION: Various clinical and laboratory characteristics differ between children and adults with IgAV/HSP. Overall, IgAV/HSP has a self-limiting course in children but represents a more severe form of disease in adults, with more severe renal involvement. Persistent haematuria is a predictive factor for relapse.

OBJECTIVES: Reactive haemophagocytic syndrome (RHS) is a hyperinflammatory disorder often occurring in the background of several disorders such as infections, malignancies, and rheumatic diseases. Recently, a score known as the HScore was developed for the diagnosis of RHS. In the original study, most of the patients had underlying haematological malignancy or infection and the best cut-off value for the HScore was 169 (sensitivity 93%; specificity 86%). In this study we aimed to analyse the performance of the HScore in rheumatic disease-related RHS. METHOD: The patients with rheumatic disorders evaluated in the Departments of Rheumatology and Paediatric Rheumatology at Hacettepe University, Ankara, Turkey between 2002 and 2014 were reviewed retrospectively. The first group (n = 30) consisted of patients with RHS; the control group (n = 64) included patients with active rheumatic diseases without RHS. RESULTS: In the RHS group, 14 (46.7%) had adult-onset Still's disease (AOSD), 10 (33.3%) systemic juvenile idiopathic arthritis (SJIA), and six (20%) systemic lupus erythematosus (SLE). The control group (n = 64) consisted of 32 (50%) AOSD, 13 (20.3%) SJIA, and 19 (29.7%) SLE patients. Applying the HScore to the RHS patients, the best cut-off value was 190.5 with a sensitivity of 96.7% and specificity of 98.4%. When we excluded the patients from the control group who had not had bone marrow aspiration (n = 23), the same cut-off (190.5) performed best (sensitivity 96.7%; specificity 97.6%). Applying the 2004 haemophagocytic lymphohistiocytosis (HLH-2004) criteria gave a sensitivity of 56.6% and a specificity of 100% in the whole study group. CONCLUSIONS: In our study, a cut-off value for the HScore different from the original study performed better. Further studies are warranted to determine optimum cut-off values in different studies.

Spondyloenchondrodysplasia (SPENCD) is a rare autosomal recessive skeletal dysplasia caused by recessive mutations in the ACP5 gene, and it is characterized by the persistence of chondroid tissue islands within the bone. The clinical spectrum of SPENCD includes neurological involvement and immune dysfunction, such as systemic lupus erythematosus (SLE). To date, there are only 12 reported cases of SPENCD associated with SLE in the literature; however, detailed clinical follow-up data is absent for this comorbidity. This report presents clinical and laboratory data of three patients diagnosed with SPENCD-associated SLE. All three patients had short stature, arthralgia/arthritis, lupus nephritis, hypocomplementemia, and positive autoantibodies, including anti-nuclear and anti-dsDNA antibodies. Two patients exhibited class IV and one patient exhibited class V lupus nephritis. The early recognition of SPENCD is imperative, and this condition should be considered in patients with SLE, particularly in individuals with short stature and skeletal abnormalities. The cases presented here demonstrate that timely diagnosis and follow-up are key factors for the successful management of these conditions.

AIM: Cystinosis is a rare autosomal recessive disorder that is characterized by defective cystine transport from lysosomes to cytoplasm and cystine crystal accumulation damaging many organs and tissues especially kidneys but extrarenal systems such as endocrine system. We aim to investigate endocrinologic complications of cystinosis METHODS: In our study, twenty one patients were reviewed retrospectively for endocrinologic complications. RESULTS: Eighteen (85.7%) had short stature, out of nine patients who reached pubertal age, five (55.5%) had pubertal delay, five patients (23.8%) had overt hypothyroidism and five patients (23.8%) had subclinical hypothyroidism with only elevated thyroid stimulating hormone (TSH) levels, seven (33.3%) had glucose intolerance, two (9.5%) had diabetes mellitus. Relation of these complications to age, renal functions and the dosage of cysteamine were studied. CONCLUSION: Endocrinologic complications of cystinosis can be seen in pediatric population and it is important to understand underlying mechanisms.

AIM: The aim of this study was to analyze the hematological features in children with systemic lupus erythematosus (SLE) and to review our current treatment protocols. METHODS: We evaluated hematological findings of 43 children with SLE diagnosed and followed at the Pediatric Rheumatology Division of Hacettepe University, Turkey. Thirty-seven patients with hematological abnormalities were analyzed in detail. RESULTS: Median age at presentation was 13 years. Hematological involvement was seen in 86% of patients. The most common hematological finding was anemia (n = 30). Anemia was either a Coombs (+) hemolytic one, or was due to other causes. Hemolytic anemia was treated with steroids and intravenous gamma globulin (IVIG). Leucopenia and thrombocytopenia were detected in 35.1 % and 37.8 %, respectively. Bone marrow aspiration was performed in 15, mainly for cytopenia. Secondary dysplastic changes were common. Acute lymphoblastic leukemia (ALL) was diagnosed in one patient. Six patients were diagnosed as having macrophage activation syndrome (MAS). One patient died due to secondary infections and multiorgan failure despite aggressive treatment. In patients diagnosed early, treatment with steroids and cyclosporine resulted in an excellent response. Thrombotic microangiopathy was detected in two patients. Both were treated successfully with steroids and plasma exchange. Antiphospholipid and anticardiolipin antibodies were positive in 12 and 15 of the patients, respectively. Five developed deep vein thrombosis (DVT), one cerebral sinus thrombosis and one presented with purpura fulminans. They were effectively treated with anticoagulation protocol. CONCLUSION: Hematological findings should be carefully assessed and treated vigorously to prevent the morbidity and possible mortality.

Haematological involvement of systemic lupus erythematosus (SLE) - which ranges from the well-described haemolytic anaemia to macrophage activation syndrome - has a large impact on both morbidity and mortality. On the other hand, association between haematological malignities and SLE - in terms of pathophysiology and molecular genetics - is an obscure entity which has not been clarified evidently to date. Herein, we present a six-year-old female with the diagnosis of SLE who developed acute lymphoblastic leukaemia following a period of myelodysplasia. It could possibly be coincidental; however, persistent cytopenia, prominent dysplasia on bone marrow smears and azathioprine treatment may be considered as possible triggers for the development of leukaemia in the present case.

BACKGROUND: Nephronophthisis (NPHP) is the most common genetic cause of end-stage renal disease (ESRD) in the first 3 decades of life. Treatment of patients with NPHP is symptomatic; kidney transplantation is the treatment of choice when ESRD is established. We report herein our center's experience with kidney transplantation for children with juvenile NPHP. PATIENTS: We retrospectively analyzed medical records of 9 renal transplant recipients with a primary diagnosis of juvenile NPHP confirmed by genetic analysis and/or renal biopsy findings in a single center from 1996 to 2010. RESULTS: Of the 9 patients, 6 received a living related and 3 a cadaveric donor transplantation. Preemptive renal transplantation was performed in 7 patients. The median age of the patients was 13.38 ± 4.6 years; the median follow-up period was 17 months. Posttransplantation immusuppression comprised corticosteroids, a calcineurin inhibitor, and mycophenolate mofetil or azathioprine. One patient lost his renal graft owing to renal graft thrombosis, and grade II chronic allograft nephropathy was diagnosed by renal biopsy on the 62th day after renal transplantation in another patient. The median glomerular filtration rates after transplantation at 1, 3, and 5 years were 85, 75.2, and 83.2 mL/min/1.73 m(2), respectively. CONCLUSION: We observed preserved graft functions for long periods among renal transplant recipients with juvenile NPHP. Chronic allograft nephropathy developed rarely on long follow-up.

OBJECTIVES: Autoinflammatory diseases constitute a large spectrum of monogenic diseases like FMF or cryopyrin-associated periodic syndromes (CAPS) and complex genetic trait diseases such as systemic onset juvenile idiopathic arthritis (SoJIA). An increased rate of MEFV mutations has been shown among patients with PAN and HSP, in populations where FMF is frequent. The aim of the study is to search for MEFV mutations in our patients with SoJIA and see whether these mutations had an effect on disease course or complications. METHODS: Thirty-five children with the diagnosis of SoJIA were screened for 12 MEFV mutations. The control data were obtained from a previous study of our centre determining the carrier frequency in Turkish population. RESULTS: Two patients were homozygous and three patients were heterozygous for the M694V mutation. One patient was a compound heterozygote for the M680I/V726A mutations. Heterozygous V726A mutation was found in one patient. The overall mutation frequency of patients was 14.28%. This figure had been compared with the previously published rate of disease-causing mutations in this country, which is 5%. Disease-causing mutations were found to be significantly more frequent in the SoJIA patients than the population (P < 0.01). Among these, M694V was the leading mutation with a frequency of 10% in SoJIA. Six patients carrying MEFV mutations were among the most resistant cases requiring biological therapy. CONCLUSION: SoJIA patients had a significantly higher frequency of MEFV mutations but clinical studies with large number of patients are needed to confirm the association of MEFV mutations with SoJIA and its course.

INTRODUCTION: Renal transplantation in patients with lower urinary tract dysfunction (LUTD) of various origins is a challenging issue in the field of pediatric transplantation. We report our single-center experience to evaluate patient and graft survivals as well as the risks of the surgery and immunosuppressive therapy. PATIENTS AND METHODS: Among 70 pediatric transplant patients, 11 displayed severe LUTD. Videourodynamic tests were performed on all patients preoperatively as well as postoperatively if required. The cause of urologic disorders were neurogenic bladder (n = 5) and urethral valves (n = 6). Clean intermittent catheterization (CIC) was needed in six patients to empty the bladder. To achieve a low-pressure reservoir with adequate capacity pretransplantation augmentation ileocystoplasty was created in four patients and gastrocystoplasty in one patient. Three of the patients received kidneys from cadaveric and eight from living donors. All patients were treated with calcineurin-based immunosuppressive therapy. RESULTS: The mean age at transplantation was 15 +/- 4.7 years. The median follow-up after transplantation was 36 months (6 to 62 months). At their last visit the median creatinine level was 0.95 mg/dL (0.8 to 2.4 mg/dL). Three patients had recurrent symptomatic urinary tract infections who had augmented bladder on CIC. One patient with ileocystoplasty who developed urinary leak and ureteral stricture in the early postoperative period was treated by an antegrade J stent. CONCLUSION: Severe LUTD carried high risks for the grafted kidney. However, our data suggested that renal transplantation is a safe and effective treatment modality, if the underlying urologic diseases properly managed during the transplantation course. Since surgery and follow-up is more complicated, patient compliance and experience of transplantation team have significant impacts on outcomes.

INTRODUCTION: The recurrence of primary disease in transplantation is a well-known problem. We report our single-center experience to assess the frequency of the recurrence of primary glomerulonephritis in children after renal transplantation. PATIENTS AND METHODS: Medical reports of 14 children with primary glomerular disease were evaluated. Among the 14 grafts were 10 from living related and four from cadaveric donors. Ten were diagnosed as focal segmental glomerulosclerosis (FSGS), two membranoproliferative glomerulonephritis (MPGN), and two polyarteritis nodosa (PAN). The original diagnosis was biopsy-proven in every case. All patients were treated with calcineurin-based immunosuppressive therapy. RESULTS: The mean age was 15.5 +/- 5.4 years. The median transplantation duration was 47 months; however, one of the FSGS patient had hyperacute rejection. Five years later she received a second graft with a serum creatinine of 0.7 mg/dL at 7 years after transplantation. Posttransplant recurrence of FSGS was confirmed in two patients (20%), who were treated with plasmapheresis with no improvement of proteinuria, two FSGS patients had thromboses after transplantation. One had a cardiac thrombosis with heterozygote MTHFR mutation and one, a renal artery thrombosis and loss of graft with prothrombin 20210A mutation. They all have functioning grafts except these two. We did not observe recurrence of PAN or MPGN in patients. CONCLUSION: Although the number of patients is quite small, our recurrence rate was compatible with the previous reports. Additionally, we strongly recommend evaluation of all risk factors for thrombosis and give appropriate anticoagulation.

AIM: In this single-center cohort, we retrospectively analyzed the efficacy and safety of tacrolimus in pediatric renal transplantation. METHODS: We examined the medical records of 22 consecutive renal transplantation recipients (12 boys, 10 girls) receiving tacrolimus, to evaluate occurrence of acute rejection (AR) episodes, glomerular filtration rates (GFR), and side effects. RESULTS: The mean recipient age was 15.07 +/- 3.96 years. Seven grafts came from cadaveric, and 15 from living related donors. The patients were placed on immunosuppression with prednisolone and tacrolimus plus azathioprine (n = 8) or mycophenolate mofetil (MMF) (n = 12) or enteric-coated mycophenolate sodium (n = 2). Eighteen patients received basiliximab on days 0 and 4. There were three AR episodes at 5, 9, and 12 months. Mean GFR at the end of 1 and 2 years were 97.1 +/- 24.0 mL/min/1.73 m(2) and 116.9 +/- 42.2 mL/min/1.73 m(2), respectively. There was no graft loss. Hypertension, hyperlipidemia, and hyperglycemia were present in 14 (63.6%), 3 (13.6%), and 3 (13.6%) patients, respectively, without gingival hyperplasia, tremor, or hypertrichosis. Supraventricular tachycardia was noticed in five patients (22.7%), three of whom needed antiarrhythmic drugs (13.6%). CONCLUSION: Our single-center experience with tacrolimus, steroid plus azathioprine or MMF or enteric-coated mycophenolate sodium regimen in pediatric kidney recipients showed a low rate of AR with excellent graft survival and function at 1 and 2 year posttransplantation. The increased rate of supraventricular tachycardia in this regimen had not been previously reported; this association merits further studies.

Our aim was to investigate the semen variables and hormone profiles among transplant patients who received kidneys during adolescence. Seven postpubertal transplant patients who underwent successful renal transplantation during adolescence (13-19 years; 3 were preemptive) were enrolled in our clinical follow-up. Serum levels of prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone were checked together with the semen analysis. The ages of the patients ranged from 18 to 25 years (median, 22 years). The median age was 15 years (range, 12-18 years) at initial presentation. The median time between initial diagnosis and transplantation was 12 months (range, 2-60 months). The median follow-up after transplantation was 51 months (range, 23-134 months). Three of the seven patients had unilateral low testicular volume. The renal function tests were within normal limits, as well as serum levels of prolactin, FSH, LH, and testosterone. Sperm counts ranged from 0.2 to 55 million/mL (median, 1.7 million/mL). Only 1 patient (14.2%) had normal sperm parameters. Oligoteratozoospermia (low sperm count and defects in morphology) was observed in 1/7 (14.2%), asthenoteratozoospermia (low levels of motility and defects in morphology) in 1/7 (14.2%), and all parameters were abnormal in 4/7 (57.1%) cases. Our data suggest that in contrast to adult patients, semen variables are severely affected and spermatogenesis does not improve after renal transplantation when the patient was subjected to uremia before or during adolescence, the crucial period for spermatogenesis.
