Testosterone replacement therapy. What is its potential in elderly men?

More than half of the men in a Swedish population of men aged 55, 65 and 75 believe in 'a male climacteric'

AIM

Symptoms of late-onset hypogonadism (LOH) are often unspecific, and the existence of a male climacteric has been much debated. In this study, we investigate aging men's thoughts about, and beliefs, in a 'male climacteric'.

METHODS

A questionnaire was developed including background demographic data, symptoms possibly related to LOH and questions about men's thoughts and beliefs in a 'male climacteric'. All men, 55-, 65- and 75-years old, living in Linkoping, Sweden (n=1885) received the questionnaire.

RESULTS

One thousand three hundred fifty-six (72%) questionnaires were eligible for evaluation, 65.4% of the responders had heard of a 'male climacteric', and 42.2% believed it existed but only 3% had sought medical advice for these symptoms. More than half believed that a 'male climacteric' was related to decreased libido and less strong erections. Almost half of the men thought that decreased memory and/or dystymia and anxiousness were related to a male climacteric.

CONCLUSIONS

The majority of men have heard of a male climacteric, but only a minority had consulted a practitioner about their symptoms. More information and knowledge are needed, for the general population to better motivate men to seek medical advice and also for the health care professionals to better deal with the symptoms of LOH.

Testosterone correlated to symptoms of partial androgen deficiency in aging men (PADAM) in an elderly Swedish population

OBJECTIVE

To investigate the prevalence of different symptoms of partial androgen deficiency in aging men (PADAM) and to correlate them with blood concentrations of testosterone and bioavailable testosterone.

DESIGN

A total of 370 men, aged 55 to 75 years, were invited to one of three primary healthcare centers in Sweden. They were asked to complete a questionnaire regarding demographic data, medical history, mood status, medication, castration therapy and smoking, exercise and alcohol habits, as well as different symptoms of PADAM. The 10 questions from a previously used questionnaire (the ADAM questionnaire) were included. The men were offered blood tests for analyses of testosterone, follicle stimulating hormone, luteinizing hormone, steroid hormone-binding globulin, and albumin. From these test results, we calculated the bioavailable testosterone.

RESULTS

Of the questionnaires sent out, 81.6% were returned and eligible for evaluation. Blood samples were obtained from 85.8% of men answering the questionnaire. Many of the symptoms, including five from the ADAM questionnaire, were more common in older age groups (P < 0.05). Three symptoms, deterioration in work performance, decreased strength and/or endurance, and bothersome hot flushes, were associated with low bioavailable testosterone and/or testosterone (P < 0.05). Testosterone and bioavailable testosterone did not differ between age groups, but bioavailable testosterone was higher in men with three or fewer symptoms on the ADAM questionnaire.

CONCLUSIONS

Symptoms associated with PADAM often occur in an elderly population, but we could only find an association between three symptoms and blood testosterone concentrations, one being bothersome hot flushes. It is likely that these symptoms have a more complex background than only PADAM.

Hot flushes in a male population aged 55, 65, and 75 years, living in the community of Linköping, Sweden

OBJECTIVE

Hot flushes are as common in castrated men as in menopausal women. We investigated whether hot flushes exist in a normal aging male population and to what extent.

DESIGN

A questionnaire was sent to all men living in Linköping, Sweden, who were 55, 65, and 75 years old ( = 1,885). The questionnaire asked for demographic data, medical history, mood status, medication, castrational therapy, and smoking, exercise, and alcohol habits, among other items. We asked specifically for current hot flushes unrelated to exercise or a warm environment.

RESULTS

Of the questionnaires received, 1,381 were eligible for evaluation; 33 were analyzed separately because these men had been castrated. Hot flushes of any frequency were reported by 33.1% of noncastrated men, 4.3% reported flushes at least a few times per week, and 1.3% reported daily flushes. Half of the men reporting flushes were also bothered by them, ie, almost every sixth man in total. We found a relation between occurrence of hot flushes and other symptoms thought to be related to low testosterone concentration, such as decreased muscle strength or endurance, decreased enjoyment of life, sadness or grumpiness, and lack of energy ( < 0.05).

CONCLUSIONS

Hot flushes occur in one third of a population of noncastrated older men, approximately half of whom consider flushes as bothersome. Neither the mechanisms nor whether the symptoms would respond to testosterone supplementation is known. Androgen substitution to treat symptoms possibly related to a male climacteric is still controversial. Studies are needed to evaluate the needs for and the effects of androgen treatment on vasomotor symptoms.

Bone and joint infections in the elderly: practical treatment guidelines

Two types of haematogenous osteomyelitis that are seen in the elderly are vertebral and long bone osteomyelitis. Osteomyelitis secondary to contiguous foci of infection can occur in older adults without vascular insufficiency (secondary to pressure ulcers) or with vascular insufficiency due to diabetes mellitus or peripheral vascular disease from atherosclerosis. Most cases of osteomyelitis can be reasonably treated with adequate drainage, thorough debridement, obliteration of dead space, wound protection, and antimicrobial therapy. Patients are initially given a broad spectrum antimicrobial that is changed to specific antimicrobial therapy based on meticulous bone cultures taken at debridement surgery or from deep bone biopsies. Surgical management is often required in the treatment of osteomyelitis and includes adequate drainage, extensive debridement of all necrotic tissue, obliteration of dead spaces, stabilisation, adequate soft tissue coverage, and restoration of an effective blood supply. Bone repair and bone mineral density may be significantly retarded and may be corrected by eliminating risk factors, supplementing the diet with calcium, bisphosphonates, and/or vitamin D, and treating with testosterone and/or estrogen when deficient. Sodium fluoride treatment and anabolic steroids may be used as alternatives. Septic arthritis is a medical emergency, and prompt recognition and rapid and aggressive treatment are critical to ensuring a good prognosis. The treatment of septic arthritis includes appropriate antimicrobial therapy and joint drainage. Adverse effects of prescribed antibacterials occur more often in the elderly patient than in young adults. The physician can help to minimise the incidence of adverse effects and improve outcomes by being aware of the principles of clinical pharmacology, the characteristics of specific drugs, and the special physical, psychological and social needs of older patients.

Perceptions of and risk factors for andropause

There has been some controversy about whether males undergo andropause (male equivalent of a menopause). This study seeks to describe how older males perceive and understand this entity. It also explores the possibility of an association between the age of onset of andropause and risk factors such as ethnic origin, smoking, alcohol, hypertension, and cerebrovascular disease. A nonexperimental, cross-sectional study was conducted at the outpatient clinic at a Veterans Affairs Medical Center. Subjects were interviewed by a single investigator and answered a questionnaire consisting of 22 items, including information on patient demographics, patient understanding of andropause, patient understanding of possible interventions with hormonal therapy, medical and drug history, and social habits such as smoking and drinking. Altogether 302 male patients were recruited: 71% of the survey population were above the age of 60 years, and 87% were white, 6% Hispanic, and 5% black. Patient knowledge of andropause was lacking, though the majority (70%) expressed an interest in getting further knowledge. The most frequent age for onset of symptoms related to andropause was 51-60 years, and patients reported symptoms such as impotence, weakness, and memory loss. The next most common age associated with onset was 61-70 years. Multivariate regression analysis revealed that smoking more than 10 cigarettes a day was independently associated with an earlier onset of andropause symptoms bringing down the age of onset to below 50 years (p = .01, OR = 2.5, CI = 1.2-5.3). We found no association with risk factors such as ethnicity or alcohol. Andropause is experienced by many older males but knowledge of the entity is nonuniform. Smokers are at risk for an earlier onset of andropause. This is the first study to look at risk factors for andropause and the results are consistent with studies in females on smoking and menopause.
