Consensus recommendations on fasting during Ramadan for patients with kidney disease: review of available evidence and a call for action (RaK Initiative).

Ramadan fasting (RF) involves abstaining from food and drink during daylight hours; it is obligatory for all healthy Muslims from the age of puberty. Although sick individuals are exempt from fasting, many will fast anyway. This article explores the impact of RF on individuals with kidney diseases through a comprehensive review of existing literature and consensus recommendations. This study was conducted by a multidisciplinary panel of experts.The recommendations aim to provide a structured approach to assess and manage fasting during Ramadan for patients with kidney diseases, empowering both healthcare providers and patients to make informed decisions while considering their unique circumstances.

Capacity for the management of kidney failure in the International Society of Nephrology Middle East region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

The highest financial and symptom burdens and the lowest health-related quality-of-life scores are seen in people with kidney failure. A total of 11 countries in the International Society of Nephrology (ISN) Middle East region responded to the ISN-Global Kidney Health Atlas. The prevalence of chronic kidney disease (CKD) in the region ranged from 4.9% in Yemen to 12.2% in Lebanon, whereas prevalence of kidney failure treated with dialysis or transplantation ranged from 152 per million population (pmp) in the United Arab Emirates to 869 pmp in Kuwait. Overall, the incidence of kidney transplantation was highest in Saudi Arabia (20.2 pmp) and was lowest in Oman (2.2 pmp). Chronic hemodialysis (HD) and peritoneal dialysis (PD) services were available in all countries, whereas kidney transplantation was available in most countries of the region. Public government funding that makes acute dialysis, chronic HD, chronic PD, and kidney transplantation medications free at the point of delivery was available in 54.5%, 72.7%, 54.5%, and 54.5% of countries, respectively. Conservative kidney management was available in 45% of countries. Only Oman had a CKD registry; 7 countries (64%) had dialysis registries, and 8 (73%) had kidney transplantation registries. The ISN Middle East region has a high burden of kidney disease and multiple challenges to overcome. Prevention and detection of kidney disease can be improved by the design of tailored guidelines, allocation of additional resources, improvement of early detection at all levels of care, and implementation of sustainable health information systems.

Health Economic Benefits of Introducing Sucroferric Oxyhydroxide in the Treatment of Patients with Chronic Kidney Disease under Dialysis in the Kingdom of Saudi Arabia.

Hyperphosphatemia is an electrolyte disorder highly prevalent in patients with chronic kidney disease undergoing hemodialysis (HD) that usually requires treatment with oral phosphate binders (PBs). Sucroferric oxyhydroxide (SO) is a calcium-free, iron-based PB indicated for the control of serum phosphorus. In the real-world setting, SO has shown clinical effectiveness with a lower pill burden and has also been associated with reduced hospital admission rates. This study aims to assess the potential economic benefits resulting from the introduction of SO to the health-care setting of the Kingdom of Saudi Arabia (KSA). An economic analysis using data from a retrospective real-world study that compared HD patients with uninterrupted SO prescriptions with patients who discontinued SO and switched to other PBs (oPBs). Annual drug costs for the estimated PB-eligible population in KSA were quantified. Costs per responder were estimated for all treatments. Hospital admissions' incidence rates were converted into annual inpatient cost savings and were deducted from drug costs to estimate the annual economic effect of SO versus oPBs. Sensitivity and breakeven analyses were also conducted. The eligible population for PB therapy in KSA was estimated at n = 14,748. Treating therapy-eligible populations exclusively with SO was estimated to generate annual inpatient cost-savings of SAR 107.4-119.4 million compared to treating the population with oPBs. The estimated economic effect signified overall annual savings ranging from SAR 82.8 to SAR 94.8 million when the population is treated with SO. Sensitivity analyses showed persistent cost savings. The estimated benefit-cost ratios showed that for every SAR 1 spent on SO, the expected return on investment was SAR 4.4-4.9. SO is an effective therapy that may result in substantial cost savings from reducing hospital admission costs that are attributable to hyperphosphatemia among HD patients.

Global Economic Burden Associated with Chronic Kidney Disease: A Pragmatic Review of Medical Costs for the Inside CKD Research Programme.

INTRODUCTION: Chronic kidney disease (CKD) is a progressive disease of growing prevalence, posing serious concerns for global public health. While the economic burden of CKD is substantial, data on the cost of CKD is limited, despite growing pressures on healthcare systems. In this review, we summarise the available evidence in 31 countries and regions and compile a library of costing methodology and estimates of CKD management and disease-associated complications across 31 countries/regions within the Inside CKD programme. METHODS: We collected country/region-specific CKD costs via a pragmatic rapid literature review of local literature and engagement with local experts. We extracted cost data and definitions from identified sources for CKD stages G3a-5, kidney failure with replacement therapy by modality, covering haemodialysis, peritoneal dialysis, and kidney transplants, and disease-associated complications in local currency, converted to United States dollars (USD) and inflated to 2022. RESULTS: Annual direct costs associated with CKD management rose by an average factor of 4 in each country/region upon progression from stage G3a to G5. Mean annual costs per patient increased considerably more from early stages versus dialysis (stage G3a, mean: $3060 versus haemodialysis, mean: $57,334; peritoneal dialysis, mean: $49,490); with estimates for annual costs of transplant also substantially higher (incident: $75,326; subsequent: $16,672). The mean annual per patient costs of complications were $18,294 for myocardial infarction, $8463 for heart failure, $10,168 for stroke and $5975 for acute kidney injury. Costing definitions varied widely in granularity and/or definition across all countries/regions. CONCLUSION: Globally, CKD carries a significant economic burden, which increases substantially with increasing disease severity. We identified significant gaps in published costs and inconsistent costing definitions. Cost-effective interventions that target primary prevention and disease progression are essential to reduce CKD burden. Our results can be used to guide cost collection and facilitate better comparisons across countries/regions to inform healthcare policy.

Mammalian Target of Rapamycin Inhibitors and Wound Healing Complications in Kidney Transplantation: Old Myths and New Realities.

Mammalian target of rapamycin inhibitors (mTOR-I) lacks nephrotoxicity, has antineoplastic effects, and reduces viral infections in kidney transplant recipients. Earlier studies reported a significant incidence of wound healing complications and lymphocele. This resulted in the uncomfortable willingness of transplant clinicians to use these agents in the immediate posttransplant period. As evidence and experience evolved over time, much useful information became available about the optimal use of these agents. Understandably, mTOR-I effects wound healing through their antiproliferative properties. However, there are a lot of other immunological and nonimmunological factors which can also contribute to wound healing complications. These risk factors include obesity, uremia, increasing age, diabetes, smoking, alcoholism, and protein-energy malnutrition. Except for age, the rest of all these risk factors are modifiable. At the same time, mycophenolic acid derivatives, steroids, and antithymocyte globulin (ATG) have also been implicated in wound healing complications. A lot has been learnt about the optimal dose of mTOR-I and their trough levels, its combinations with other immunosuppressive medications, and patients' profile, enabling clinicians to use these agents appropriately for maximum benefits. Recent randomized control trials have further increased the confidence of clinicians to use these agents in immediate posttransplant periods.

Diabetes Prevalence, Treatment, Control, and Outcomes Among Hemodialysis Patients in the Gulf Cooperation Council Countries.

Introduction: Diabetes mellitus (DM) is a leading cause of end-stage kidney disease (ESKD). We provide the first description of DM prevalence, related outcomes, and the hemoglobin A1c (HbA1c)/mortality relationship in national hemodialysis (HD) patient samples across the Gulf Cooperation Council (GCC) countries. Methods: We analyzed data from the prospective Dialysis Outcomes and Practice Patterns Study (DOPPS) in the GCC (2012-2018, N = 2274 HD patients ≥18 years old). Descriptive statistics were calculated, and all-cause mortality was analyzed for patients with DM versus without DM and by HbA1c levels in patients with DM by Cox regression with progressive confounder adjustments. Results: DM in the GCC ranged from 45% to 74% in patients with HD by country. Patients with DM were 13 years older (59.9 vs. 46.7 years) and had greater body mass index (BMI), shorter median years on dialysis (1.5 vs. 3.0 years), and higher comorbidity burden. In patients with DM, insulin use was 26% to 50% across countries, with variable oral antidiabetic drug use (2%-32%); median HbA1c levels were 6.1% to 7.5% across countries. Patients with DM (vs. without DM) had higher crude death rates (15.6 vs. 6.2 deaths per 100 patient-years, mean follow-up 1.3 years) and adjusted mortality (hazard ratio [HR] = 1.72 [95% CI 1.23-2.39]). In patients with DM, mortality was lowest at HbA1c 6.5% to 7.5%, with mortality particularly elevated at high HbA1c >9% (HR = 2.13 [95% CI 1.10-4.10]). Conclusion: Patients with DM in the GCC have high comorbidity burden and mortality rates despite a relatively young mean age. In GCC countries, a holistic strategy for improving diabetes care and outcomes for HD patients is needed at the primary, secondary, and tertiary levels.

COVID-19 breakthrough infections in rheumatic diseases patients after vaccination.

BACKGROUND: Rheumatic diseases patients receiving Rituximab had severe COVID-19 disease. Although they had impaired humoral immune responses following COVID-19 vaccine, they had preserved cellular immune responses. Waning of COVID-19 antibody responses was observed within six months post vaccination among immunocompromised patients. Recent reports showed fatal outcome of breakthrough SARS-CoV-2 infections among vaccinated high-risk rheumatic diseases patients receiving Rituximab. SAR-CoV-2 serological tests were not performed. OBJECTIVE: Evaluation of COVID-19 vaccine humoral responses and breakthrough infections among low risk fully vaccinated rheumatic patients during the Delta Variant Era. METHODS: A case series of 19 fully vaccinated patients with rheumatic diseases were followed to determine post vaccine SARS-CoV-2 neutralizing antibody titers and to monitor the development of breakthrough infections up to eight months post vaccine at our tertiary care center in Jeddah, Saudi Arabia from 1st April until 30th November 2021. RESULTS: The mean age of patients was 49 years old. 10% of patients were receiving Rituximab. 73% of patients had positive SARS-CoV-2 serological testing post second vaccine. Two mild breakthrough COVID-19 infections were diagnosed six months post second dose of vaccine. Patients were less than 65 years, did not receive Rituximab, did not have interstitial lung diseases and had positive post vaccine serological testing. CONCLUSIONS: We demonstrated high SARS-CoV-2 neutralizing antibodies seroprevalence and self-limiting breakthrough infections in low risk rheumatic diseases patients during the Delta Era. Future studies are needed to study the outcome of rheumatic diseases patients in the Era of Omicron in view of viral immune escape responses.

Cerebral venous sinus thrombosis in Saudi Arabia.

OBJECTIVE: To analyze the clinical patterns, etiologies, treatment, and outcome of cerebral venous sinus thrombosis (CVST) in 2 major cities of Saudi Arabia, Jeddah and Al-Baha. METHODS: One hundred and eleven patients diagnosed as CVST were identified from the medical records at King Abdulaziz Medical City, Jeddah, and King Fahad Hospital, Al-Baha, Saudi Arabia, from January 1990 through November 2010. We retrospectively analyzed the data, compared it with local and international studies, and reviewed the literature. RESULTS: There were 92 adults and 19 children. Among adults, females predominated, while more boys were affected than girls. The mean age of onset was 29.5 years. The most common clinical presentations were headache, focal neurologic deficits, seizures, papilledema, and decreased level of consciousness. The main risk factors identified were pregnancy/ puerperium, antiphospholipid antibody syndrome, oral contraceptive pills, malignancy, and infections. Multiple sinuses were affected in 51 patients (45.9%). When a single sinus was involved, the superior sagittal sinus (24.3%) was the most common. Seventy-four patients recovered completely, 23 patients recovered partially, and 10 patients died. Bad prognostic factors included incurable co-morbid conditions, late presentation, and status epilepticus. CONCLUSION: Pregnancy/puerperium was the most common etiological factor in our series. Clinical features were similar to international series. Behcet`s disease was not a major etiological factor in our series. Most patients had involvement of multiple sinuses. Prompt treatment with anticoagulation resulted in complete or partial recovery in 87.4% of patients.

Saudi Registry of Cardiovascular Risk Factor Management in Hemodialysis Patients: The Results of SECRET-HD Study.

Chronic kidney disease (CKD) patients on hemodialysis (HD) present cardiovascular (CV) risk factors, which increase mortality rates but could be alleviated with proper medical care. The primary aims of this study are determining CV risk factor prevalence and medications prescribed for those patients in the Kingdom of Saudi Arabia (KSA). The study is a national, multicenter, noninterventional study performed in seven clinics/hospitals throughout KSA. Adult CKD patients undergoing HD were included. Data on CV risk factors, medications prescribed, and achievement of risk factor control was collected on two three-monthly visits, along with details of HD sessions. Study outcomes are displayed as rates. Numerical and categorical variables were presented. Statistical tests were performed using SAS (v.9.2 for Windows; SAS Institute, Cary, NC, USA). Virtually all 389 patients (99.7%) had at least one CV risk factor. Hypertension was the most common traditional risk factor (75.0%), while CKD-mineral and bone disorder (MBD) and anemia closely competed for the highest reported nontraditional risk factors. Antihypertensives, erythropoietin, and phosphate binders were prescribed to over 70% of patients, followed by iron supplements and Vitamin D. Most patients achieved blood pressure (73.3%) and diabetes (64.8%) targets set at baseline, and around 50% for dyslipidemia, anemia, malnutrition, and hemostatic disorder, while only 23% achieved CKD-MBD targets. Most of the 12,852 HD sessions (85%) were complication-free; 165 (44.2%) patients experienced extracorporeal thrombosis incidents (none was severe). Saudi CKD patients are very likely to present CV risk factors (99.7% prevalence), which seem successfully managed. HD is safely practiced, and possible complications are properly addressed.

Kt/V: achievement, predictors and relationship to mortality in hemodialysis patients in the Gulf Cooperation Council countries: results from DOPPS (2012-18).

BACKGROUND: Dialysis adequacy, as measured by single pool Kt/V, is an important parameter for assessing hemodialysis (HD) patients' health. Guidelines have recommended Kt/V of 1.2 as the minimum dose for thrice-weekly HD. We describe Kt/V achievement, its predictors and its relationship with mortality in the Gulf Cooperation Council (GCC) (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates). METHODS: We analyzed data (2012-18) from the prospective cohort Dialysis Outcomes and Practice Patterns Study for 1544 GCC patients ≥18 years old and on dialysis >180 days. RESULTS: Thirty-four percent of GCC HD patients had low Kt/V (<1.2) versus 5%-17% in Canada, Europe, Japan and the USA. Across the GCC countries, low Kt/V prevalence ranged from 10% to 54%. In multivariable logistic regression, low Kt/V was more common (P < 0.05) with larger body weight and height, being male, shorter treatment time (TT), lower blood flow rate (BFR), greater comorbidity burden and using HD versus hemodiafiltration. In adjusted Cox models, low Kt/V was strongly related to higher mortality in women [hazard ratio (HR) = 1.91, 95% confidence interval (CI) 1.09-3.34] but not in men (HR = 1.16, 95% CI 0.70-1.92). Low BFR (<350 mL/min) and TT (<4 h) were common; 41% of low Kt/V cases were attributable to low BFR or TT (52% for women and 36% for men). CONCLUSION: Relatively large proportions of GCC HD patients have low Kt/V. Increasing BFR to ≥350 mL/min and TT to ≥4 h thrice weekly will reduce low Kt/V prevalence and may improve survival in GCC HD patients-particularly among women.

Self-reported Pruritus and Clinical, Dialysis-Related, and Patient-Reported Outcomes in Hemodialysis Patients.

RATIONALE & OBJECTIVE: Chronic kidney disease (CKD)-associated pruritus, generalized itching related to CKD, affects many aspects of hemodialysis patients' lives. However, information regarding the relationship between pruritus and several key outcomes in hemodialysis patients remains limited. STUDY DESIGN: Prospective cohort. SETTING & PARTICIPANTS: 23,264 hemodialysis patients from 21 countries in the Dialysis Outcomes and Practice Patterns Study (DOPPS) phases 4 to 6 (2009-2018). EXPOSURE: Pruritus severity, based on self-reported degree to which patients were bothered by itchy skin (5-category ordinal scale from "not at all" to "extremely"). OUTCOMES: Clinical, dialysis-related, and patient-reported outcomes. ANALYTICAL APPROACH: Cox regression for time-to-event outcomes and modified Poisson regression for binary outcomes, adjusted for potential confounders. RESULTS: The proportion of patients at least moderately bothered by pruritus was 37%, and 7% were extremely bothered. Compared with the reference group ("not at all"), the adjusted mortality HR for patients extremely bothered by pruritus was 1.24 (95% CI, 1.08-1.41). Rates of cardiovascular and infection-related deaths and hospitalizations were also higher for patients extremely versus not at all bothered by pruritus (HR range, 1.17-1.44). Patients extremely bothered by pruritus were also more likely to withdraw from dialysis and miss hemodialysis sessions and were less likely to be employed. Strong monotonic associations were observed between pruritus severity and longer recovery time from a hemodialysis session, lower physical and mental quality of life, increased depressive symptoms, and poorer sleep quality. LIMITATIONS: Residual confounding, recall bias, nonresponse bias. CONCLUSIONS: Our findings demonstrate how diverse and far-reaching poor outcomes are for patients who experience CKD-associated pruritus, specifically those with more severe pruritus. There is need for change in practice patterns internationally to effectively identify and treat patients with pruritus to reduce symptom burden and improve quality of life and possibly even survival.

Insomnia in chronic renal patients on dialysis in Saudi Arabia.

BACKGROUND: Studies have shown that insomnia is a common sleep disorder among patients with end-stage renal disease (ESRD). This study aimed to assess the prevalence of insomnia in Saudi patients with ESRD who are on maintenance dialysis. METHODS: This was an observational cross-sectional study carried out over a period of five months in two hemodialysis centers in Saudi Arabia. To assess the prevalence of insomnia, we used the ICSD-2 definition. We also examined the association between insomnia and other sleep disorders, the underlying causes of renal failure, dialysis duration, dialysis shift, and other demographic data. RESULTS: Out of 227 enrolled patients, insomnia was reported by 60.8%. The mean patient age was 55.7 +/- 17.2 years; 53.7% were male and 46.3% were female. Insomnia was significantly associated with female gender, afternoon hemodialysis, Restless Legs Syndrome, high risk for obstructive Sleep Apnea Syndrome and excessive daytime sleepiness (P-values: 0.05, 0.01, < 0.0001, < 0.0001, and < 0.0001, respectively). No significant association was found between insomnia and other variables, including BMI, smoking habits, underlying etiology of renal failure, dialysis duration, association with hemoglobin, ferritin, and phosphorus or dialysis adequacy as measured by the Kt/V index. CONCLUSION: Insomnia is common in dialysis patients and was significantly associated with other sleep disorders. Greater attention needs to be given to the care of dialysis patients with regard to the diagnosis and management of insomnia and associated sleep disorders.

Pattern of Laboratory Parameters and Management of Secondary Hyperparathyroidism in Countries of Europe, Asia, the Middle East, and North America.

INTRODUCTION: This analysis explored laboratory mineral and bone disorder parameters and management of secondary hyperparathyroidism in patients undergoing hemodialysis in Belgium, Canada, China, France, Germany, Italy, Japan, Russia, Saudi Arabia, Spain, Sweden, the UK, and the USA. METHODS: Analyses used demographic, medication, and laboratory data collected in the prospective Dialysis Outcomes and Practice Patterns Study (2012-2015). The analysis included 20,612 patients in 543 facilities. Descriptive data are presented as regional mean (standard deviation), median (interquartile range), or prevalence, weighted for facility sampling fraction. No testing of statistical hypotheses was conducted. RESULTS: The frequency of serum intact parathyroid hormone levels > 600 pg/mL was lowest in Japan (1%) and highest in Russia (30%) and Saudi Arabia (27%). The frequency of serum phosphorus levels > 7.0 mg/dL was lowest in France (4%), the UK (6%), and Spain (6%), and highest in China (27%). The frequency of serum calcium levels > 10.0 mg/dL was highest in the UK (14%) and China (13%) versus 2% to 9% elsewhere. Dialysate calcium concentrations of 2.5 mEq/mL were common in the USA (78%) and Canada (71%); concentrations of 3.0-3.5 mEq/L were almost universal at facilities in Italy, France, and Saudi Arabia (each ≥ 99%). CONCLUSIONS: Wide international variation in mineral and bone disorder laboratory parameters and management practices related to secondary hyperparathyroidism suggests opportunities for optimizing care.

Parathyroid Hormone Serum Levels and Mortality among Hemodialysis Patients in the Gulf Cooperation Council Countries: Results from the DOPPS (2012-2018).

Background: The prospective Dialysis Outcomes and Practice Patterns Study (DOPPS) has collected data since 2012 in all six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates). We report the relationship of PTH with mortality in this largest GCC cohort of patients on hemodialysis studied to date. Methods: Data were from randomly selected national samples of hemodialysis facilities in GCC-DOPPS phases 5 and 6 (2012-2018). PTH descriptive findings and case mix-adjusted PTH/mortality Cox regression analyses were based on 1825 and 1422 randomly selected patients on hemodialysis, respectively. Results: Mean patient age was 55 years (median dialysis vintage, 2.1 years). Median PTH ranged from 259 pg/ml (UAE) to 437 pg/ml (Kuwait), with 22% having PTH <150 pg/ml, 24% with PTH of 150-300 pg/ml, 34% with PTH 301-700 pg/ml, and 20% with PTH >700 pg/ml. Patients with PTH >700 pg/ml were younger; on dialysis longer; less likely to be diabetic; have urine >200 ml/d; be prescribed 3.5 mEq/L dialysate calcium; had higher mean serum creatinine and phosphate levels; lower white blood cell counts; and more likely to be prescribed cinacalcet, phosphate binders, or IV vitamin D. A U-shaped PTH/mortality relationship was observed with more than two- and 1.5-fold higher adjusted HR of death at PTH >700 pg/ml and <300 pg/ml, respectively, compared with PTH of 301-450 pg/ml. Conclusions: Secondary hyperparathyroidism is highly prevalent among GCC patients on hemodialysis, with a strong U-shaped PTH/mortality relationship seen at PTH <300 and >450 pg/ml. Future studies are encouraged for further understanding this PTH/mortality pattern in relationship to unique aspects of the GCC hemodialysis population.

An Observational Registry to Assess Urinary Albumin Evolution in Saudi Hypertensive Patients with the Current Treatment Local algorithm: Results of the RATIONAL Study.

INTRODUCTION: Hypertension causes microalbuminuria, which if left uncontrolled could progress to kidney damage. Antihypertensive treatment primarily aims at controlling blood pressure (BP), but is also shown to control urine albumin excretion. This renoprotective role of antihypertensive medications consists of halting or reverting albuminuria progression. PATIENTS AND METHODS: A national Kingdom of Saudi Arabia (KSA), multicenter, observational, longitudinal study (RATIONAL), evaluated the correlation between BP control and microalbuminuria evolution over 1 year. Adult hypertensive patients with kidney damage were enrolled, after giving written consent. RESULTS: Of 409 patients, 60% had uncontrolled BP at baseline, down to 34% at 12 months. Over 80% of patients were on mono or double antihypertensive therapy, and angiotensin-receptor blockers (ARB) topped the list of medication classes. Albumin-creatinine ratio (ACR) significantly decreased throughout the study, indicating that BP control is paramount to prevent target organ damage. BP change most strongly correlated with ACR change upon triple therapy (ARB + calcium channel blocker + ß-blocker). Importantly, 25% (at 6 months) and 38% (at 12 months) of patients reverted back to normoalbuminuria, mostly upon renin-angiotensin system blockers. Around 80% of study patients had also diabetes, a common condition in KSA, which significantly hindered achievement of normoalbuminuria at 12 months. CONCLUSION: A modest but solid correlation between BP control and ACR reduction was identified. Results underline proper BP management in KSA and success of antihypertensive treatment in reverting microalbuminuria or delaying its progress. The study duration might be insufficient to reflect conclusively the beneficial effect of longer-term BP control on microalbuminuria evolution.

Kidney transplant from sickle cell trait donor to sickle cell trait recipient.

There have been concerns about using kidneys from potential donors with sickle cell trait because kidneys from these donors may not concentrate urine properly. We report a case of living-related renal transplant, in which both the recipient and the donor had sickle cell trait, and the postoperative course for both was uneventful.

Superiority of peginterferon α-2a and ribavirin combination over peginterferon α-2a monotherapy in the management of hemodialysis patients with chronic Hepatitis C virus infection.

Hepatitis C virus (HCV) is a common infection affecting 15% of hemodialysis population in Saudi Arabia resulting in delay in transplantation and long-term complications. The use of peginterferon resulted in sustained virologic response (SVR) in 40%-85% of patients, especially if combined with ribavirin. The treatment is hampered by the high dropout due to anemia and requirement of blood transfusion resulting from this therapy. Some studies have shown that the addition of increasing dose of erythropoiesis-stimulating agents (ESA) and reduced dose of ribavirin results in reduced dropout rate with high SVR. We conducted an open-label prospective study using either peginterferon α-2a alone (Group I, 32 patients) or peginterferon α-2a plus adjusted dose ribavirin (Group II, 26 patients). A total of seven patients dropped from the study (2 in Group I and 5 in Group II). Analysis was done only on patients who completed the study (thirty patients in Group I and 21 in Group II). There was no significant difference in the demographic data, HCV genotype, liver biopsy grade and stage, and laboratory tests between the two groups. Patients received ESA to combat expected anemia. Group II had a better early virologic response than Group I [17 out of 21 (80%) and 14 out of 30 (47%) respectively, P = 0.014] and better SVR [18 out of 21 (85%) and 15 out of 30 (50%) respectively, P = 0.009]. There were no differences in mean white blood cells, hemoglobin, and platelets between the two groups at any time with only four patients dropping out due to anemia or side effect of medications. Alanine aminotransferase was lower in both treatment groups compared to baseline with no difference between the groups. Peginterferon α-2a and ribavirin are superior to peginterferon α-2a alone in treating hemodialysis patients with chronic HCV infection.

Verticillium Species Skin Infection in a Renal Transplant Patient.

Verticillium species is a filamentous fungus that inhabits decaying vegetation and soil. It is known to cause disease in plants. Four cases of human infections have been reported previously in nontransplant patients. Here, we report the first case of Verticillium species skin infection in a transplant patient who was successfully treated with fluconazole monotherapy.

Isolated neuropathy of the recurrent motor branch of the median nerve.

Unlike carpal tunnel syndrome, isolated neuropathy of the recurrent motor branch of the median nerve is a rare condition as a cause of thenar muscle wasting. A focused neurophysiological approach is mandatory to reach the proper diagnosis and start specific treatment early enough to prevent possible irreversible hand function disabilities. This is a description of 16-year-old female patient who presented with isolated thenar muscle wasting for 3 years. A focused neurophysiologic approach using abductor pollicis brevis and second lumbrical muscles for recording of median nerve motor conduction and index finger for sensory conduction proved isolated neuropathy of the recurrent motor branch of the median nerve.

Cardiovascular and cerebrovascular comorbidities in hemodialysis patients from the Gulf Cooperation Council countries enrolled in the dialysis outcome and practice pattern study phase 5 (2012-2015).

To determine the prevalence of cardiovascular comorbidities and their active risk factors in the selected hemodialysis centers in the Gulf Cooperation Council (GCC) countries, the Dialysis Outcome and Practice Pattern Study (DOPPS) was performed on 40 dialysis centers in the six GCC countries from June 2012 to May 2015. There were 21 dialysis centers from Saudi Arabia, nine from the United Arab Emirates (UAE), four from Kuwait, four from Oman, two from Qatar, and one from Bahrain. There were 922 patients participating in the study; 419 patients from Saudi Arabia, 144 from the UAE, 164 from Kuwait, 89 from Oman, 58 from Qatar, and 25 from Bahrain. Baseline data and laboratory investigations were obtained from every study patient, and the patients with any new events, change of dialysis prescription, or death were reported to the DOPPS main center during follow-up. The median age of the patients in the GCC centers was 55 years (range 32- 80 years), and the median percentage of males was 57%. The most common cause of chronic kidney disease among the study patients was diabetes mellitus (median: 43%) followed by hypertension (median: 29%) and glomerulonephritis (median: 9%). Hypertension (median 90%) and diabetes mellitus (median 52%) were the most common predisposing comorbidities to cardiovascular events in the study patients. The median ratios of patients with coronary artery disease, peripheral vascular disease, and congestive heart failure were 34%, 23%, and 24%, respectively. The median ratio for cerebrovascular comorbidities was 9%. The median prevalence of the factors that may predispose to the cardiovascular and cerebrovascular comorbidities such as gender of the patients, adequacy of dialysis, diabetes, hypertension, hypercholesterolemia, levels of anemia, parathormone levels, and calcium and phosphorus levels in the GCC countries were comparable with those in the previous DOPPS in other countries.
