Potential role of serum fetuin-A in relation with pro-inflammatory, chemokine and adhesion molecules in diabetic kidney disease: a case-control study.

Inflammatory cytokine, adipokine and adhesion molecules are known to play a key role in pathogenesis of diabetic kidney disease (DKD). In this study, our aim was to investigate the role of fetuin-A in relation with pro-inflammatory cytokines (IL-6, IL-18), adipokines (adiponectin, leptin), chemokine (MCP-1), and adhesion molecules (ICAM-1, VCAM-1) in control and DKD subjects. We recruited a total of 224 type 2 diabetic (T2D) subjects. The control subjects were T2D with a normal albumin excrete (albumin-to-creatinine ratio-ACR ≤ 30 mg/g creatinine) and estimated glomerular filtration rate (eGFR) ≥ 60 (ml/min/1.73 m2), while cases were T2D subjects with albumin excrete (ACR ≥ 30 mg/g creatinine) and eGFR ≤ 60 (ml/min/1.73 m2). FBS, HbA1c, lipid profile (TC, LDL, HDL, triglyceride), ALT, AST, GGT, serum creatinine, BMI, blood pressure was evaluated in all the study subjects. Randox evidence biochip analyzer was used for measuring inflammatory cytokines, adipokines, and adhesion molecules by chemiluminescent assay. Serum fetuin-A and IL-18 were measured by ELISA kits. Serum fetuin-A levels were significantly decreased in DKD cases compare to control group [456.8 (299.2-649.0) µg/ml versus 670.6 (573.0-726.1) µg/ml; p < 0.001)]. Serum fetuin-A levels correlates significantly with IL-6, IL-18, TNF-α, PAI-1, leptin, resistin and ACR (p < 0.001). This study concludes that serum fetuin-A and pro-inflammatory markers (IL-18, IL-6, IL-1α and TNF-α) might play an important role in the pathophysiology and inflammatory process of DKD.

Association Between Type B Insulin Resistance Syndrome and Mixed Connective Tissue Disease in an Arab African Man.

Type B insulin resistance syndrome (TBIRS) has not been previously reported in Arab populations. We report a case of TBIRS in an Arab patient with mixed connective tissue disease (MCTD). Investigations revealed a clinical condition marked by positive anti-insulin receptor and ribonucleoprotein antibodies. The patient presented with severe hyperglycemia, weight loss, arthralgia, and acanthosis nigricans. He was managed successfully with an intensive pulsed combination regimen of cyclophosphamide and plasmapheresis augmented with high doses of prednisolone, which normalized his blood sugar levels without insulin therapy. MCTD was controlled by hydroxychloroquine. During the course of his treatment, the patient developed diabetic ketoacidosis secondary to the gluteal abscess, leukopenia, and recurrent hypoglycemia. Here, we showed that immunosuppressive agents and plasmapheresis can induce remission of TBIRS and can be used to normalize the blood sugar levels of Arab patients with this condition.

Characteristics of Patients with Charcot's Arthropathy and its Complications in the Saudi Diabetic Population: A Cross-Sectional Study.

BACKGROUND: Charcot's arthropathy (CA) is a destructive rare complication of diabetes, and its diagnosis remains challenging for foot specialists and surgeons. We aimed to assess the clinical presentation and characteristics of CA and the frequencies of its various types. METHODS: This cross-sectional study was conducted from January 1, 2007, to December 31, 2016, and included 149 adults with diabetes diagnosed as having CA. Cases of CA were classified based on the Brodsky anatomical classification into five types according to location and involved joints. RESULTS: The mean ± SD age of the studied cohort was 56.7 ± 11 years, with a mean ± SD diabetes duration of 21.2 ± 7.0 years. The CA cohort had poorly controlled diabetes and a high rate of neuropathy and retinopathy. The most frequent type of CA was type 4, with multiple regions involved at a rate of 56.4%, followed by type 1, with midfoot involvement at 34.5%. A total of 47.7% of the patients had bilateral CA. Complications affected 220 limbs, of which 67.7% had foot ulceration. With respect to foot deformity, hammertoe affected all of the patients; hallux valgus, 59.5%; and flatfoot, 21.8%. CONCLUSIONS: There is a high rate of bilateral CA, mainly type 4, which could be attributed to cultural habits in Saudi Arabia, including footwear. This finding warrants increasing awareness of the importance of maintaining proper footwear to avoid such complications. Implementation of preventive measures for CA is urgently needed.

A rare thyroid hormone receptor beta (THRß) gene mutation in a 15-year-old girl with thyroid hormone resistance syndrome: a case report.

INTRODUCTION: Resistance to thyroid hormone is a rare syndrome, where although the level of thyroid hormone is elevated, the level of thyroid stimulating hormone is not suppressed. The patient in our case report is, to the best of our knowledge, the first with this syndrome identified in Oman. CASE PRESENTATION: In one Omani family, a 15-year-old girl of Arabian origin was pre-diagnosed with resistance to thyroid hormone. Blood sample was collected and deoxyribonucleic acid was isolated for molecular genetic testing. The results revealed a rare mutation A268G in the gene for thyroid hormone receptor beta. We believe that this mutation is the cause of the pathology in our patient. CONCLUSION: We report the presence of a rare mutation in the thyroid hormone receptor beta gene for the first time in the Omani population. Due to the rates of consanguinity being high among the Omani population, we are aiming to screen our patient's family members and provide genetic counseling.

Quality of diabetes care in primary health centres in north Al-batinah of oman.

OBJECTIVE: To assess the quality of diabetic care provided in primary health care settings in Oman. METHODS: This was a cross-sectional study of randomly selected 500 patients with diabetes mellitus (DM) attending 6 primary care diabetic clinics in the north Al-Batinah region of Oman from January to December 2010. Nine standards on the quality of diabetes care were audited. RESULTS: The mean age of the sample was 51±13 years, ranging from 15 to 87 years; the majority (61%) were females. The mean duration of DM was 4±3 years, ranging from 1 to 18 years. Seventy-seven percent of the patients attended diabetic clinics at least 4 times per year. Of the 9 assessed diabetic standards, HbA1c was documented in 33% of the patients, body mass index in 12%, low-density lipoprotein cholesterol (LDL-C) in 40%, urinary albumin:creatinine ratio in 28%, creatinine in 63% and blood pressure (BP) in 96%. Optimal control among the documented indicators was noted in 32, 21, 25, 85, 95 and 19%, respectively. Twenty percent of the patients had their ECGs done while only 39% of the patients had foot examination. No patient had attained control in all of HbA1c., BP and LDL-C. CONCLUSION: There is a gap between the recommended DM care guidelines and current practice with consequent poor quality of care in these patients.

Pilot study on the prevalence of abuse and mistreatment during clinical internship: a cross-sectional study among first year residents in Oman.

OBJECTIVE: To evaluate perceptions of being mistreated during internship among first year Oman Medical Specialty Board residents. DESIGN: A cross-sectional study. SETTING: Training centres for Oman Medical Specialty Board. PARTICIPANTS: First year medical residents following completion of internship during the study period 2009-2010. METHOD: A cross-sectional survey of first year medical residents. RESULTS: Of 58 residents (response rate 84%), 96.6% perceived that mistreatment exists. Among different types of mistreatment reported, verbal and academic abuses were the most common (87.9%), followed by sexual harassment (24.1%), then physical abuse (22.4%). Forty-four (75.9%) residents had advised at least one of their relatives not to join medical school. CONCLUSIONS: Mistreatment of medical interns is an ethical issue challenging the quality of clinical training. Further research is needed to understand factors influencing mistreatment and to draw guidelines to limit such problems.
