Wills-Balfour-McSweeney Syndrome

Wills-Balfour-McSweeney syndrome: understanding a rare disease

Wills-Balfour-McSweeney syndrome, also known as megalocytic subtropical anemia of pregnancy, is a rare disease that is named after the doctors who contributed significantly to its research and description. This syndrome causes megalocytic anemia in pregnant women and can have serious health consequences for both mother and baby.

Wills, Balfour and McSweeney, who each contributed to the study of this syndrome, were doctors who conducted research in the early 20th century. Although the exact causes of Wills-Balfour-McSweeney syndrome are still unknown, it is believed to be associated with nutritional deficiencies and certain genetic factors.

The main symptom of this syndrome is megalocytic anemia, which means an increase in the size of red blood cells in the blood. This leads to a decrease in the number of functional red blood cells capable of delivering sufficient oxygen to the tissues. Pregnant women with Wills-Balfour-McSweeney syndrome may experience fatigue, weakness, shortness of breath and other symptoms related to lack of oxygen.

It is important to note that Wills-Balfour-McSweeney syndrome can pose a threat to the health and life of both the mother and the developing fetus. When there is a lack of oxygen, the fetus can be susceptible to a number of complications, including growth retardation, premature birth and low birth weight. Therefore, early recognition and diagnosis of this syndrome is important to ensure adequate treatment and monitoring.

Treatment of Wills-Balfour-McSweeney syndrome usually involves comprehensive support and management of anemia. This may include taking supplements containing essential nutrients such as iron, folic acid and vitamin B12. In some cases, blood transfusions may be required to improve hemoglobin levels and oxygen metabolism.

Although Wills-Balfour-McSweeney syndrome is a rare disease, research and educational programs about it are needed to increase awareness and ensure timely diagnosis. Pregnant women should contact their doctor if they experience unexplained weakness, fatigue, or other symptoms of anemia. Early recognition and treatment of Wills-Balfour-McSweeney syndrome can help improve outcomes for mother and child.

In conclusion, Wills-Balfour-McSweeney syndrome is a rare disorder characterized by megalocytic anemia in pregnant women. It can have serious consequences for the health of the mother and fetus. Early detection, diagnosis and adequate treatment are key to ensure the best results. Greater dissemination of knowledge about the syndrome and its symptoms among the medical community and pregnant women can help in increasing awareness and timely care for patients suffering from this rare disease.



Wills-Balfour syndrome is one of the hereditary metabolic diseases that manifests itself mainly during fetal development, very rarely after the birth of a child, and rarely in old age. The prevalence of the disease ranges from 3 to 6 cases per 1 million population. In most people suffering from this pathology, the syndrome is combined with dysfunction of the liver and gastrointestinal tract, mental disabilities, and often hypoplasia of the gonads. In about a third of patients, the disease proceeds without severe impairment. At the same time, cases of almost complete recovery have been described, subject to timely diagnosis and adequate treatment. C 199
