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.

Multi-drug-resistant tuberculosis in a patient presenting with bilateral gluteal abscesses and right leg swelling with end-stage renal disease.

This is a 40-year-old woman with end-stage renal disease (ESRD). She received empirical treatment for presumed TB of the right knee joint. The arthritis and the constitutional symptoms resolved despite the patient's poor compliance. One year later, she presented with TB abscesses involving the upper end of right tibia and bilateral gluteus muscles, which proved to be resistant to isoniazid, rifampicin and ethambutol. The patient was successfully treated with pyrazinamide, ofloxacin and amikacin.

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.

Spontaneous singleton and twin pregnancy in two patients with polycystic ovary syndrome and type 2 diabetes following treatment with metformin combined with rosiglitazone.

Two women, a Saudi Arab and a Caucasian, aged 28 and 41 years, had a long history of polycystic ovary syndrome (PCOS) and primary infertility, which was refractory to various treatment modalities. Both later developed type 2 diabetes, managed initially with metformin; rosiglitazone was added later to improve glycaemic control. Both conceived spontaneously, resulting in singleton and twin pregnancies giving birth to healthy babies. The combination of rosiglitazone with metformin may result in improved fertility with ovulation and spontaneous conception in women with PCOS and type 2 diabetes. Randomized controlled trials are needed to assess the feasibility of this combination to improve fertility in women with PCOS. However, in the absence of any safety data, those women, following counselling, should be warned against the possibility of spontaneous pregnancy and contraceptive measures should be discussed and offered where appropriate.
