Comparison of health status and quality of life of related versus paid unrelated living kidney donors.

The aim of this cross-sectional study was to assess the health status and quality of life (QOL) of paid unrelated versus related living kidney donors postdonation at Shiraz Transplant Center in Iran. We invited all donors (n = 580, 347 paid unrelated, 233 related) who underwent donor nephrectomy at our center from 2004 to 2010 to participate in a health survey and physical examination. Of 580 donors, 144 consented to participate; participation of paid unrelated donors was significantly lower than related (52/347 vs. 92/233; p < 0.001). Participants underwent a complete physical examination, QOL assessment (using a 36-item short form health survey [SF-36] questionnaire) and laboratory work-up. The paid unrelated donors compared with related donors were younger (34.2 ± 7.2 vs. 40.7 ± 9.7 years, p < 0.001), had shorter time since donation (2.9 ± 1.6 vs. 3.8 ± 2 years, p = 0.004), had higher estimated GFR (72.6 ± 22 vs. 63.8 ± 15.3 mL/min/1.73 m(2), p = 0.006) and had a higher percentage of patients with microalbuminuria (35% vs. 0%, p < 0.001). Additionally, general health and social functioning scores among paid unrelated donors were significantly lower (p < 0.001 and p = 0.02, respectively) than related donors. Other SF-36 scores, although lower in paid unrelated donors, did not reach statistical significance. Iranian paid unrelated donors have lower QOL and higher incidence of microalbuminuria compared with related donors.

Granulomatous liver involvement in a child with systemic lupus erythematosus: a case report and review of the literature.

Systemic lupus erythematosus (SLE) is uncommon in young children and unusual in infancy. Although a variety of liver pathologies have been reported in SLE, presentation of this disease with granulomatous liver involvement is very rare. In this article, for the first time, we report an infant girl presenting with unexplained hepatosplenomegaly and non-necrotizing granulomatous liver involvement at the age of six months who later developed pancytopenia and proteinuria and was finally diagnosed with SLE at the age of three years. Therefore, we suggest that SLE could be considered as one of the possible differential diagnoses when infants or children present with unexplained granulomatous liver involvement.

Evaluation of growth and body mass index in children following kidney transplantation.

Growth retardation is common among children with chronic kidney disease (CKD). Renal transplantation has beneficial effects on height and weight gain of children, but height gain occurs especially for those children who are transplanted at a younger age. This study was conducted for a cross-sectional evaluation of growth and body mass index (BMI) in children following kidney transplantation. All children who had been transplanted in our center and had regular follow-up were entered in this study. Those with primary non-functioning grafts were excluded from the study. Weight and height at transplantation and at 20 years of age or at a pre-determined period (1-4-2008 to 30-6-2008) were recorded. Their height, weight, BMI, standard deviation score (SDS) of height and weight at their pre- and post-transplantation period were compared. SPSS 15.1 software and paired t-test were used for comparison of means. Seventy-one children, 43 boys and 28 girls, were involved in this study. The mean age at transplantation was 12.6 ± 3.45 years, ranging from 3 to 19 years, and age at last visit was 16.9 ± 3.15 years. They had been followed-up for 7-175 months (mean, 51.6 ± 30.75 months). Their primary renal diseases were as follows: reflux, obstruction and dysplasia 29 (41%), hereditary 25 (35%), glomerular disease 14 (20%), unknown 3 (4%). Source of donor was living related in 27 (38%), with 15 being mothers, deceased in 35 (49%) and living unrelated in 9 (13%). SDS height improved dramatically in post-transplantation evaluation, but this did not happen for SDS weight and BMI. We can conclude that despite a dramatic effect of transplantation on growth, catch-up growth only occurred in a minority of the children.

Mortality from Pandemic Influenza A (H1N1) in Iran.

BACKGROUND: Due to worldwide spread of influenza A (H1N1) virus, the World Health Organization declared the first pandemic of influenza in four decades. This study aims to report the mortality from pandemic influenza A (H1N1) in Iran population and its epidemiologic and clinical characteristics up to December 21, 2009. METHODS: The data were obtained from all provinces and reported to center for disease control of Ministry of Health and Medical Education (MOHME) of Iran through nationwide surveillance system for influenza A (H1N1) was implemented by MOHME since April 2009. RESULTS: Of 3672 confirmed cases of influenza A (H1N1) in Iran between 22 May and 21 December 2009, 140 (3.8%) deaths were reported, mostly in 15-65 year old (yo) age group (67%). The highest admission mortality rate was in > 65 yo group (107 deaths/1000 hospitalized cases). Of decedent patients, 54% had no long term condition or risk factor, 34% had one, 11% had two, and 1% had three. Diabetes mellitus, pregnancy, chronic respiratory diseases and hypertension were the most common underlying conditions. The most common clinical pictures of death were acute respiratory distress syndrome and viral pneumonia. Although 66% of decedent patients received oseltamivir, enough information was not available about time of onset of antiviral therapy. CONCLUSION: As death due to influenza A (H1N1) occurs in all age groups and in those with and without any predisposing factors, we recommend health policy makers to provide influenza vaccination for people with underlying conditions and respiratory hygiene for all people.

Hypercalciuria in children with urinary tract symptoms.

We performed this prospective study to determine the urinary calcium to creatinine ratio (Ca/Cr) in children with different urinary symptoms. We studied 523 children in our nephrology clinic with an age range of 3 to 14 years (mean= 8) and male to female ratio of 0.61. All the children had at least one of the urinary tract symptoms (dysuria, frequency, urgency, abdominal and/or flank pain, diurnal incontinence or enuresis), microscopic hematuria, urinary tract infection or urolithiasis. Fasting urine was collected for measuring calcium and creatinine and the results were compared to the values for the normal Iranian children. Ca/Cr ratio of more than 0.2 (mg/mg) was considered as hypercalciuria. Of all the patients, 166 (31.3%) were hypercalciuric. Urine Ca/Cr ratio was significantly higher in all the subgroups with one or more of the urinary symptoms (P< 0.001). We conclude that urine Ca/Cr ratio is significantly increased in children with all types of urinary symptoms. We recommend measuring urinary calcium in all children with urinary tract symptoms, especially if unexplained.

Proton pump inhibitors: predisposers to Alzheimer disease?

The abnormal processing of amyloid-beta peptide (A beta) and resultant formation of fibrillar A beta (fA beta) are major events in the pathogenesis of Alzheimer disease (AD). Microglia as the phagocytic cells of the brain can engulf and digest fA beta within their acidic lysosomes. The lysosomes of AD patients are less acidic and therefore less capable of clearance of fA beta. Vacuolar proton pumps (V-ATPases) which are found abundantly in microglia and macrophages, acidify lysosomes by pumping protons into these structures. Proton pump inhibitors (PPIs) can inhibit V-ATPases of the lysosomes. These drugs are shown to penetrate the blood-brain barrier in animals. PPIs are consumed for long periods in conditions such as gastroesophageal reflux disease, with the resultant exposure of the human brain to the substantial amounts of PPIs. We hypothesize that by blocking the V-ATPases on microglial lysosomes, PPIs may basify lysosomes and hamper degradation of fA beta. Chronic consumption of PPIs may thus be a risk factor for AD.

Rubeosis faciei diabeticorum: a common, but often unnoticed, clinical manifestation of diabetes mellitus.

In this clinical image, we present the picture of a diabetic patient with rubeosis faciei diabeticorum, a relatively common, but usually unnoticed, microangiopathic complication of diabetes mellitus that could herald other more notorious microangiopathic complications of diabetes mellitus, such as retinopathy. This case will help other physicians to consider rubeosis faciei diabeticorum whenever they face similar cases.
