Although sickle cell disease has long been viewed as a contraindication to free flap transfer, little data exist evaluating complications of microsurgical procedures in the sickle cell trait patient. Reported is the case of a 55-year-old woman with sickle cell trait who underwent a deep inferior epigastric perforator (DIEP) microvascular free flap following mastectomy. The flap developed signs of venous congestion on postoperative day two but was found to have patent arterial and venous anastomoses upon exploration in the operating room. On near-infrared indocyanine green angiography, poor vascular flow was noted despite patent anastomoses and strong cutaneous arterial Doppler signals. Intrinsic microvascular compromise or sickling remains a risk in the sickle cell trait population as it does for the sickle cell disease population. Just like in sickle cell disease patients, special care should be taken to optimize anticoagulation and minimize ischemia-induced sickling for patients with sickle cell trait undergoing microsurgery.

Abstract The relative rates of incorporation of Fe59 into heterogenic hemoglobins was studied in four patients with sickle cell trait. Three of the patients were free of superimposed disease, while one had active pulmonary tuberculosis. In all subjects there was a significantly greater incorporation of radioiron, per milligram of hemoglobin, into hemoglobin S than into hemoglobin A. The data indicate that in sickle cell trait the rates of synthesis of the heterogenic hemoglobins are not proportional to their circulating concentrations. Two interpretations appear possible. Since the size of the intra-marrow pool of hemoglobin S was not known, it is possible that there exists a smaller preformed pool of the abnormal hemoglobin, with the isotope making its appearance first in hemoglobin S. However, it is also possible that hemoglobin S is synthesized at a rate which is greater than that reflected by its circulating concentration. This implies that the relative concentrations of hemoglobin S and hemoglobin A vary from erythrocyte to erythrocyte, and that those cells with the greatest proportion of hemoglobin S are selectively destroyed.

<p class="Pa7">Sickle cell anemia (SCA) is a common hematological disorder among individu­als of African descent in the United States; the disorder results in the production of abnormal hemoglobin. It is caused by homozygosity for a genetic mutation in HBB; rs334. While the presence of a single mutation (sickle cell trait, SCT) has long been considered a benign trait, recent research suggests that SCT is associated with renal dysfunction, including a decrease in estimated glomerular filtration rate (eGFR) and increased risk of chronic kidney disease (CKD) in African Americans. It is currently unknown whether similar associations are observed in Hispanics. Therefore, our study aimed to determine if SCT is associated with mean eGFR and CKD in a sample of 340 Dominican Hispanics from the Northern Manhattan Study. Using regression analyses, we tested rs334 for association with eGFR and CKD, adjusting for age and sex. eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equa­tion and CKD was defined as eGFR &lt; 60 mL/min/1.73 m2. Within our sample, there were 16 individuals with SCT (SCT carriers). We found that SCT carriers had a mean eGFR that was 12.12 mL/min/1.73m2 lower than non-carriers (P=.002). Additionally, SCT carriers had 2.72 times higher odds of CKD compared with non-carriers (P=.09). Taken together, these novel results show that Hispanics with SCT, as found among African Americans with SCT, may also be at increased risk for kidney disease.</p><p class="Pa7"><em>Ethn Dis. </em>2017; 27(1)<strong>:</strong>11-14; doi:10.18865/ed.27.1.11.</p><p class="Pa7"> </p>
