J Minim Invasive Surg Sci.
Klinefelter syndrome is a disorder of chromosomes in which common karyotype is (47XXY). Hypogonadism, gynecomastia and azoospermia could be detected in this syndrome. Decreased basal metabolic rate and interest in activities, loss of muscle mass, weight gain, the deficiency of sex hormone and mood changes cause obesity which cause morb obese in this case.
A 34-year-old morbid obese (BMI = 60.40) male was come to the Laporoscopy research center of Iran University of Medical science at 26 January 2016. He was diagnosed as Klinefelter syndrome by genetic testing (47XXY karyotype). He reported suffering from knee cellulitis, headache, low back pain and varices. His nutrition habits was fast eating, Sweet eating and Snack eating. The beginning of his obesity was in his childhood. The best treatment for his obesity and its side-effects is altering in his life style, low calorie diet. Finally, if these methodes fail to lose weigth, bariatric surgery is suggested.
In morbid obese patients apporopriate diet, change in calorie intake and life style should be considered as a first line of treatment and finally, surgery may be an option to treat obesity. These two methodes can often help reduce the risk of other diseases (e.g., diabetes, heart disease, and sleep apnea) that are associated with severe obesity.

Klinefelter syndrome (KS) is a disorder in which male physical and cognitive development changes and signs differ individually. (47 XXY) is the most karyotype in this syndrome (
1). KS is the most common sex chromosomal disorder. Mostly, the extra copy of X chromosome cause this genetic syndrome ( 2). KS usualy remains unrecognized and only of 25% KS patients are diagnosed ( 3).
Possible symptoms are as follows: testicular dysfunction, azoospermia, decreased libido, gynecomastia ,increased plasma gonadotropins in males , increased risk of the metabolic syndrome, and change in body composition, with accumulation of body fat and decreased muscle mass (
1, 4). Risk factors for metabolic syndrome identify in childhood and include obesity ( 5). This disease presented itself in childhoodby delayed development of speech, learning disabilities and they have infertility, reduced body hair, gynecomastia, and tall stature later in their life ( 6).
Phenotypes of this disorder are: Small testicles, disability in sperm producing, gynecomastia, decrease of serum testosterone, increases of luteinizing hormone (LH) and follicle stimulating hormone (FSH) (
Testosterone replacement therapy may be used as medical treatment for thos who have low level of this hormone and consequences of hypogonadism (
7). Failure to produce sex hormones can cause metabolic syndrome, obesity, and diabetes mellitus ( 5). Testosterone treatment is recommended to reduce abdominal fat and increase lean mass and muscle strength ( 7).
Here we report a case of Klinefelter syndrome with morbid obesity before bariatric surgery.
2. Case Presentation
2.1. Patient Information
A 34-year-old morbid obese (BMI = 60.40, Weight: 225 kg, Height: 193 cm) male came to the Laporoscopy research center of Iran University of Medical science at 26 January 2016. He reported suffering from knee cellulitis, headache, low back pain and varices. His nutrition habits was Fast eating, Sweet eating and Snack eating. The beginning of his obesity was in his childhood. He is non- smoker and nondrinker and has no addiction to drugs. He take ciprofloxacin and clindamycin medicine.
2.2. Diagnostic Assessment
He diagnosed as Klinefelter syndrome by genetic testing (47XXY karyotype). Hormone testing shows increases in luteinizing hormone (LH = 14, normal rate: 2 - 9.5 mL) and follicle stimulating hormone (FSH = 21 normal rate: 3 - 8.7 mL) and decreased in serum testosterone (= 7, normal rate: 9 - 30 ng/dL), other lab tests are mentioned in table 1. Fatty liver grade 1 was diagnosed by Sonography. Doppler Sonography shows significant back flow at saphenofemoral junction, great saphenous vein, insufficiency in medial leg perforators venus, medial legs superficial varicose veins and gaiter venous ulcers. There is no skin pigmentation and no sign of DVT (deep vein thrombosis).

Physical Examination
Physical examination shows small genital (hypogonadotropic hypogonadism).
As common befor surgery low calorie diet was suggested,Surgery usualy is considered as a treatment option for patients with a BMI of 40 kg/m
2 or more who fails to lose wigth by exercise or diet program.
Testestrone therapy and psychiatrist visits was done for him. The millon clinical multiaxial inventory - third edition (MCMI-III) test has shown that he has obsessive characteristic and anxiety due his morbid obese. Moderate excersise and changes in lifestyle was recommednded to him. Morbid obesity are serious and potentially life-threatening conditions. A healthy lifestyle that includes a healthy diet and mild exercise are important for him. In the first visit we recommended him change his wrong habits and two weeks later we suggested him to use a diet by administered calories (1800 calories), besides change in life style and healthu diet is recommended for him. A consulting session about long-term side effects of surgery, such as possible need for reoperation, gallbladder disease, and malabsorption was conducted.
2.5. Follow up and Outcomes
Weight loss was followed and after 4 month his BMI decreases from 225 kg/m
2 to 194.87 kg/m 2.Weight lost during 6 weeks was significant (changhe score was 30.2 kg/m 2). Our future perspective is bariatric surgery. Bariatric surgery is an option to treat this morbid obese patient. It can often help reduce the risk of other additional diseases such as diabetes, heart disease, and sleep apnea that are concomitant with severe obesity (e.g.).
Klinefelter syndrome is the most common sex chromosome anomaly and is associated with weight abnormalities.The most patients with Klinefelter syndrome have (47XXY) karyotype (
3). The number of X chromosomes in Klinefelter syndrome patients affects phenotypes and severity of symptoms ( 5). Morbid obesity is not common in these patients, and it is likely related to the X chromosome structural changes ( 3). Failure to produce sexual hormones, low body energy and decreased interest in activity and other symptoms of this disorder can cause obesity. This rare case is presented here to emphasise both the significance of genetic model of morbid obesity and the need for assessment of comorbidities in such patients.
In this case recommended treatments for obesity are change in eating habits, lifes tyle and doing exercise thenaftere the final approach was bariatric surgery. This case report demonstrates appropriate treatment for this patient and the important role of sexual hormones and chromosomal abnormalities on weight changes, besides changing in eating habits is also crucial in their treatment and wigth lose too.
Recent studies report KS is associated with abdominal obesity and increased risk of metabolic syndrome. Although patients with KS have abdominal adiposity, their BMI is normal and decrease in muscle mass, increase in body fat and change in body composition are common in this patients (
4, 8). Testosterone treatment cause Decrease in fat mass. Increased body fat mass in KS is seen in childhood and adolescence ( 5).
Information is little about the impact of KS on weight and it is not clear that this morbid obesity is related to chromosomal abnormalities, hypogonadism or other hormonal conditions. The aim of reporting present case is to examine whether KS is associated with morbid obesity and how a suitable diet can help this person.
This is controversial issue that morbid obesity is caused by KS itself or affected by hypogonadism (
However, the association between KS and morbid obesity is vague; this article is the first description of KS that is associated with morbid obesity. Also an important role of dietitians who work and consult with morbid obese patients, to investigate the possible association between morbid obesity and KS is raised.
