The burden of HCV among prevalent hemodialysis patients after the National Egyptian HCV Eradication program.

In the first phase of its treatment program, Egypt aimed to treat 250,000 people annually until 2020, thereby reducing the number of viremic patients and limiting hepatitis C virus (HCV) transmission. Egypt strives to eradicate HCV and HCV-associated morbidity by 2030. This study aimed to determine the prevalence of HCV infection among end-stage renal disease patients and the reasons for non-treatment among those offered free medication. This multi-center cross-sectional study was conducted during the period from November 2022 to April 2023. The study included 500 patients receiving hemodialysis (HD) sessions on a regular basis for more than three months in Dakahlia Governorate. According to patients` medical history, we found that 23.4% of patients had previous HCV infection. Of these, 12.6% received treatment, and 10.8% did not receive treatment due to a variety of reasons. For instance, some patients were unaware of the drug's availability, five patients (1%) feared side effects, 43 patients (8.6%) did not require treatment, and five patients (1%) had other causes as contraindications of drugs, noncompliance and deterioration of health status. In addition, 20.4% of patients were reported to have fully recovered, while 0.8% had a recurrence. After investigations, 1% of patients had positive hepatitis B surface antigen (HbsAg), 23.4% positive HCV Ab, and 4.2% positive HCV by the polymerase chain reaction. In conclusion, the low prevalence of HCV among HD patients confirms that HCV infection is not currently a significant health concern among patients on maintenance HD.

Study of the effect of vitamin D supplementation on glycemic control in type 2 diabetic prevalent hemodialysis patients.

Vitamin D is claimed to have an adjuvant effect on glycemic control by dual action on pancreatic ß-cells and insulin resistance. The aim of this study was to assess the possible effect of short-term alfacalcidol supply on glycemic control in type 2 diabetic hemodialysis (HD) patients. Twenty type 2 diabetic HD patients (using diet and oral drugs but not insulin) were randomly selected from our dialysis unit as well as 20 non-diabetic HD patients as control. A third group of 12 healthy subjects were studied as well. All three groups were similar in age, sex, and body mass index. Oral alfacalcidol therapy was administrated daily as recommended by Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines for 12 weeks guided by monthly serum phosphorus and Cax PO4 product. Corrected total calcium, phosphorus, intact parathyroid hormone, 25-hydroxy vitamin D (25[OH]D), and glucoparameters (fasting blood glucose, glycated hemoglobin [HbA1c%], insulin resistance by homeostatic model assessment, and ß-cell function by HOMA-ß%) were measured under basal conditions and after 3 months of therapy. 25(OH)D was non-significantly lower in diabetic than non-diabetic HD patients, but significantly lower than healthy subjects at the start of the study. However, vitamin D level increased significantly after 3 months of trial, although the levels did not reach normal values. This vitamin D rise was associated with highly significant improvement in concentrations of fasting blood sugar (FBS), fasting insulin, HbA1c%, and HOMA-ß-cell function in diabetic and non-diabetic controls. However, there was a significant rise in insulin resistance after treatment. The percentage of change was evident more in diabetics regarding FBS and 25(OH)D concentration. Adjustment of 25(OH)D level in type 2 diabetic prevalent HD patients may improve, at least with short-term therapy, glycemic control mainly through improving ß-cell function.
