Insights
Different classifications for hypertensive disorders in pregnancy exist, causing confusion. These systems vary in defining preeclampsia, considering symptoms like edema, and staging disease progression, impacting clinical understanding and management.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Hypertensive Disorders of Pregnancy
Background:
- Existing classifications for hypertensive disorders in pregnancy, including those from the American College of Obstetricians and Gynecologists (ACOG), Organization of Gestosis (OG), and International Society for Study of Hypertension in Pregnancy (ISSHP), exhibit significant discrepancies.
- These differences can lead to misunderstandings among clinicians regarding diagnosis and severity, particularly concerning preeclampsia and eclampsia.
Purpose of the Study:
- To analyze and compare the key differences between the ACOG, OG, and ISSHP classification systems for hypertensive disorders in pregnancy.
- To highlight potential areas of confusion and misinterpretation arising from these varying definitions and criteria.
Main Methods:
- Comparative analysis of the diagnostic criteria, symptom inclusion (e.g., edema), and staging of disease progression across the ACOG, OG, and ISSHP classifications.
- Examination of terminology used for conditions such as preeclampsia, eclampsia, and related hypertensive states.
Main Results:
- Significant variations exist in the definition of "preeclampsia" (e.g., ACOG includes hypertension and albuminuria/edema; ISSHP includes hypertension and albuminuria).
- The OG and ACOG classifications provide staging based on disease progression, which is absent in the ISSHP system.
- Disagreements are noted regarding the role of edema as a diagnostic criterion, with ISSHP excluding it, ACOG considering it with hypertension, and OG accepting persistent edema alone as indicative of gestosis.
Conclusions:
- The heterogeneity among major classification systems for hypertensive disorders in pregnancy necessitates a clearer, unified approach to improve diagnostic accuracy and clinical management.
- Understanding these classification differences is crucial for obstetricians to avoid misinterpretations and ensure appropriate patient care for conditions like preeclampsia and eclampsia.
Abstract:
Three classifications: of the American College of Obstetricians and Gynecologists (ACOG), of the Organization of Gestosis (OG) and of the International Society for Study of Hypertension in Pregnancy (ISSHP) differ among one another in some essential points. According to ACOG the term "preeclampsia" means a state with hypertension and albuminuria or edema, according to ISSHP--hypertension and albuminuria. This may lead to serious misunderstanding as many obstetricians use this term to identify a directly threatening eclampsia attack. But the two classifications do not provide a term for such a condition whereas according to OG this state is identified as threatening eclampsia. The OG and ACOG classifications give a classifications according to the progression of the disease, the ISSHP does not give such a classification. ISSHP does not consider edema as a symptom, ACOG takes it into consideration if it is accompanied by hypertension according to OG the very edema not subsiding after relaxation is enough to diagnose gestosis E. ISSHP has introduced the term "hypertension in pregnancy", but also includes one-symptom form "pregnancy albuminuria" not accompanied by hypertension. Such terms suggest lack of etiological relation between those forms, which has not however been proved. The names of one-symptom forms according to OG "gestosis H" and "gestosis P" do not impose such a relation (it is a classification according to symptoms), but they do not exclude it. Contrary to ACOG and OG, ISSHP gives the level of diastolic blood pressure only.
