Menarche
Age of menarche 12-13yo Well-nourished populations, developed countries At 15yo: 98% of girls will have had menarche
Within 2-3 years of thelarche At Tanner Stage IV breast development
ACOG Committee Opinion, 2015

Cycle length
Varies widely WHO study of 3,073 girls
Median length of 1st cycle after menarche was 34d 38% of cycle lengths exceeded 40d 10% of females had >60d between 1st and 2nd menses
7% had a first-cycle length of 20d
During early years, cycles may be somewhat long because of anovulation

By 3rd yr after menarche 60–80% of menstrual cycles are 21–34d

Ovulation
Earlier menarche associated with earlier ovulatory cycles If <12yo at menarche, 50% girls have ovulatory cycles
in 2nd year If later-onset menarche, may take 8-12 years until
cycles fully ovulatory

Heavy menstrual bleeding (HMB)
Regular bleeding that is heavy or prolonged Heavy
Blood loss/cycle >80ml Soaking through pad/tampon in 1 hr Soaking through bedclothes Clots >1 inch
Prolonged >7 days

Significance of HMB in adolescence
Anemia 9-16% prevalence of iron deficiency in girls 16-19 Highest prevalence
Decreased QOL Increased school absences Decreased participation in social activities,
sleepovers, travel, and sports

Anovulation
Most common cause of HMB in adolescents
Emans and Laufer 2012
![Page 20: HEAVY MENSTRUAL BLEEDING IN ADOLESCENTS · Bleeding history Menses >7 days, soaking through pads/tampons, or impairment of daily activities History of treatment for anemia Family](https://reader030.vdocuments.mx/reader030/viewer/2022041301/5e1045a72441700c574fb4ab/html5/thumbnails/20.jpg)
Anovulation
Majority of cycles are anovulatory for 1st 2 years But many girls have “normal” cycles
Delayed maturation of negative feedback cycle Rise in E2 does not cause ↓ FSH Results in incomplete shedding of proliferative endometrium Bleeding heavy, prolonged, irregular
![Page 21: HEAVY MENSTRUAL BLEEDING IN ADOLESCENTS · Bleeding history Menses >7 days, soaking through pads/tampons, or impairment of daily activities History of treatment for anemia Family](https://reader030.vdocuments.mx/reader030/viewer/2022041301/5e1045a72441700c574fb4ab/html5/thumbnails/21.jpg)
Sustained anovulation
Eating disorders Weight changes Athletic competition Chronic illness Stress Drug abuse Endocrine disorders PCOS
![Page 22: HEAVY MENSTRUAL BLEEDING IN ADOLESCENTS · Bleeding history Menses >7 days, soaking through pads/tampons, or impairment of daily activities History of treatment for anemia Family](https://reader030.vdocuments.mx/reader030/viewer/2022041301/5e1045a72441700c574fb4ab/html5/thumbnails/22.jpg)
Severity of anovulatory bleeding
Mild Longer than normal menses or shortened cycles for ≥2 months Slightly or moderately increased menstrual flow Hgb usually normal, may be mildly decreased (10-12 g/dL)
Moderate Moderately prolonged (eg, >7 days) or frequent menses every
one to three weeks Moderate to heavy flow Hgb ≥10 g/dL
Severe Heavy bleeding that leads to decrease in hgb (to <10 g/dL) May cause hemodynamic instability

Approach to evaluation of teen with HMB
Can simply observe if recent menarche Further evaluation if:
Continuous spotting Cyclic bleeding with superimposed bleeding throughout
the cycle Anemia Persistent heavy bleeding

When to test for bleeding disorders
ACOG vWD screening in adolescents with severe HMB
ACOG + AAP Hematologic disorders (especially vWD) should be considered in
subjects with HMB
Bleeding history Menses >7 days, soaking through pads/tampons, or impairment of daily
activities History of treatment for anemia Family history of bleeding disorder Excessive bleeding with surgery or delivery
Heavy cyclic bleeding since menarche Significant drop in hgb or hgb<10

When to test for bleeding disoders
Are we testing? n=673 (Medicaid claims data) HMB diagnosis x 2 21% screened for anemia
Severe HMB: n=107 Inpatient stay for HMB, iron-def anemia, or blood
transfusion 24% screened for vWD 3% of severe dx with bleeding disorder

Hormonal treatment of HMB
Minimal data in adolescents First-line = combined oral
contraceptives (COCs) Cyclic, extended-cycle, or continuous Well-suited to short-term treatment
But…any hormonal contraception can be considered first line

Oral norethindrone
Retrospective review of norethindrone in adolescents N=176 prescribed norethindrone 0.35mg dailyMost common indication HMB (32.9%) Contraindication to estrogen
Discontinuation rate = 48.5% Irregular bleeding
Can increase dose!
Taper given to 20 patients with acute HMB 78.9% stopped bleeding <7 days

Hemostatic treatment of HMB
• DDAVP– Stimulates release of vWF– Use for <48hr
• Antifibrinolytics– Aminocaproic acid– Tranexamic acid 1300mg tid x 5d– Use for <5 days

DDAVP versus tranexamic acid
Crossover prospective study N=116 (adults)
HMB + abnl coags/platelet function
Assigned to intranasal desmopressin (DDAVP) or tranexamic acid (TA) x 2 cycles Switched x 2 cycles
Both decreased PBAC scores but TA more effective DDAVP-64.1, TA-105.7
Both improved quality of life

Oral tranexamic acid vesus COCs
Pilot study Randomized crossover N=17 (adolescents)Only 9 completed both arms
PBAC score significantly improved with TA and COC No difference
COC: Decreased length of cycle TA: Improved compliance, less side effects

Tranexamic acid
Prospective, non-blinded efficacy study of 25 girls <18yo with HMB 1300mg tid x 5 days for 4 cycles (first with no TA)
In all, improvement in PBAC and MIQ (Menorrhagia Impact Questionnaire) No serious adverse effects

Failed medical therapy at 24-36 hours EUA to exclude pelvic pathology D&C rarely indicated If suspect endometrial proliferation or intrauterine
pathologyMay worsen bleeding
Hysterectomy very rarely indicated

Treatment of acute AUB
Suction D&C and foley balloon tamponade 12yo w/ PAI deficiency during 2nd menses

How are we treating acute AUB in adolescents?
Retrospective chart review N=150 Presented to ED, treatment by mainly ED physicians
Single and multidose taper OCPs Norethindrone IV estrogen
CBC performed in only 50% Not related to vital signs

Conclusions
Menstrual cycle as vital sign Know the normal ranges
Large differential for HMB in adolescents Often anovulatory
Initiate further workup if concerning aspects or warning signs
Treatments are hormonal or hemostatic Consider use of tranexamic acid
