PART 1 CHAPTER VIII
1.8.1.
The Prevalence and Pattern of the Sexually Transmitted Infections
Sexually
transmitted diseases, once called venereal diseases, are among the most common
infectious diseases worldwide. This list of diseases now include not only
the historic venereal diseases, such as syphilis, gonorrhea and chancroid, but
also more than 20 other diseases, syndromes or complications for which sexual
transmission is of epidemiological importance. The incidence of STDs and
their sequel have increased dramatically over the past two decades all over
the world. The WHO estimated that each year some 333 million people worldwide
become infected with STDs. STDs affect men and women of all backgrounds
and economic levels. They are most prevalent among teenagers and young adults.
Nearly two-third of all STDs occurs in people younger than 25 years of age. Estimates on the magnitude of the STD problem are based mainly on
clinical data or special national surveys.
Until
now there has been little information on the prevalence and pattern of the
principal STDs in Armenia. The Ministry of Health collected clinical-based
data for a few STDs, mainly Gonorrhea and Syphilis. According to the official
estimate in Armenia, in 1992, there were 12.0 cases of Gonorrhea and 7.1 cases
of Syphilis reported per 100,000 population. These rates increased up to 30.7
cases of Gonorrhea and 17.4 cases of Syphilis per 100,000 population, in 1996. However, underreporting of STDs is widespread in Armenia. Data on
reported STDs are affected by differences in the completeness in reporting
between the public and private health care sectors. Some reasons for
underreporting are the social mores and the social stigma of seeking care at a
venereal disease clinic.
In
this questionnaire-based study we analyzed the history of diseases, disorders,
clinical signs and symptoms suggestive of the previous or current STDs during
the life span of respondents. As much as possible the interviewers tried to
obtain the confidence of interviewees, however, responses are dependent upon
the personal biases of individuals who participated in this survey.
According to the information obtained (Figure 1.8.1), the most frequently reported STDs in Armenia are Trichomoniasis and Gonorrhea. This survey shows that the frequencies of both Gonorrhea and Trichomoniasis cases are higher than might be expected. About 10 out of 100 Armenian men below 45 years of age ever have been infected with Trichomoniasis (10%), and 8 out of 100 men ever have had Gonorrhea (8%). Gonorrhea affects human fertility primarily through infections of the upper genital tract of both women and men. Obstructions of the epididymis or vas deferens associated with Gonococcal infection are causally related to subsequent infertility in the male partners.
Chlamydial
infections of the sex organs are more common than gonorrhea and are a major
public health problem today worldwide. Chlamydia Trachomatis causes about 50%
of certain male uro-genital infections, including non-gonococcal urethritis
and epididymitis. Up to 70% of patients with the infection may have no
symptoms. Untreated disease can cause subsequent infertility. In the
United States it is the most frequently occurring bacterial cause of STDs. In
Armenia, Chlamydial infections, and their consequences are not well known and
reportable, yet. It was diagnosed only in about 2% out of 1400 respondents of
this survey.
Syphilis
is highly prevalent in developing countries. In the developed countries the
rates have declined but in the recent years increased dramatically.
This survey found that proportion of Armenian men below 45 years of age, who
have been ever infected with Syphilis was 4 per 1000 (0.4%).
1.8.2.
The Clinical Signs and Symptoms Suggestive of the STDs In this study we analyzed not only the history of specific STDs, but also the variety of clinical signs and symptoms for which sexual transmission is of epidemiological importance. This survey found that more than 14% of men from the total survey sample ever have had discharge from the urethra, about 11% of men ever have had irritation or pruritis of the genitals, and 11% have had history of pain or burning while passing urine (Figure 1.8.2). Their admitted uro-genital symptoms indicate that the actual rates of the specific STDs might be higher than reported and underscore the importance of health education for men and their physicians.
About
0.7% of men (7 out of 1000) ever have had painful sores or vesicles on or
around the sex organs. The intact vesicle is the strongest clinical indication
of Genital Herpes, which prevalence has increased in recent years in the
United States. Another sign of Genital Herpes is multiple genital ulcers,
which occur when the vesicles rupture. This symptom was described by 0.4% of
respondents. The Genital Warts or Condylomas, which are caused by the Human
Papillomavirus, were reported by 0.5% of respondents (5 out of 1,000).
1.8.3.
Genito-urinary Diseases and Disorders with Possible Sexual and / or
Reproductive Health Sequels Figure 1.8.3 demonstrates the percentage distribution of men according to the history of genito-urinary diseases and disorders. The history of Cystitis was mentioned by 5% of respondents, Prostatitis - by 4% and Urethritis- by another 4%. Among other genito-urinary diseases and disorders were mentioned Phimosis/ Paraphimosis (2.5%), Urethral stricture (1.5%), Hydrocele (0.8%), Inguinal Lymphadenopathy (0.5%), and Epididimitis (0.1%). STDs cause many of these diseases and disorders. The usual cause of Epididimitis is infection spreading down the vas deferens from the bladder or urethra. The inflammation may spread also to the testicle affecting sperm production and leading to infertility.
The
history of Varicocele was reported by 0.5% of the survey respondents (5 out of
1000). This disorder in some cases is associated with a poor sperm count and
is a cause of infertility. However, often it is asymptomatic and remains
unrecognized. The reported rates of Cryptorchidism was about 0.1% (1 out of
1000). This is the condition in which testes fail to descend into the scrotum
and are retained within the abdomen or inguinal canal. A surgical operation is
necessary to bring the testes into the scrotum before puberty to allow
subsequent normal development. It is thought that the higher temperature in
the abdomen interferes with sperm production and predisposes a male to
testicular carcinoma.
1.8.4.
Access to and the Quality of Medical Care
Prevention
and control of STDs is based on four major concepts: 1) public education with
emphasis on those at risk, 2) detection of infected individuals, 3) effective
diagnosis and treatment, and, 4) evaluation, counseling and treatment of sex
partners.
This
study revealed that accessibility to sexual health counseling and clinical
services for Armenian men is not sufficient. Many infected persons either did
not apply for medical care or received ineffective treatment, which resulted
in recurrent infection and long-term consequences for sexual and reproductive
health.
Information
provided in Table 1.8.1 represents
the proportion of men with recurrent uro-genital diseases and symptoms, which
are related to STDs. For treatable STDs, effective counseling and treatment of
both partners can prevent further re-infection. Table 1.8.2. demonstrates the proportion of men with genito-urinary diseases and disorders, according to their access to effective sexual health care. Results show that a significant proportion of men suffering from genito-urinary diseases and disorders either do not receive treatment, or it is ineffective.
Physicians
and other health providers have a critical role in prevention of the spread of
the STDs. When diagnosed and treated early, almost all STDs, except for
HIV/AIDS and Genital Herpes, can been treated effectively. However, some
microorganisms, such as certain forms of gonococci, have become resistant to
the drugs used to treat them and require newer types of antibiotics. The
treatment of severe or frequently recurrent genital herpes helps control the
symptoms but does not eliminate the herpes virus from the body. In fact,
chlamydial infections and trichomoniasis are treatable with the specific
drugs, if both partners are treated simultaneously.
The data obtained from this survey indicate a lack of access by men with the history of sexually transmitted infections to qualified and effective sexual health care. Thus, for example, about 26% of men infected with the Chlamydia, 19% with the Fungal infection and 13% with the Trichomoniasis either did not get any treatment or it was not effective (Table 1.8.3).
As
demonstrated above, a significant proportion of men with urethral discharge
(12%), dysuria (18%), genital itching or erythema (12.5%), genital vesicles
(44%), and multiple genital ulcers (17%) reported that they did not receive an
adequate sexual health care.
1.8.5.
Evaluation and Treatment of Sex Partners
One
of the major concepts of prevention and control of STDs is evaluation,
counseling and treatment of sex partners. In Armenia, Syphilis and Gonorrhea
are reportable diseases. Reporting assists local health authorities in
identifying sex partners who may be infected. However, because of the stigma
associated with STDs, infected persons often seek out medical care from
private practitioners and are inclined not to identify their infected sex
partners. Many STDs initially cause no symptoms, particularly in women. As a
result of not reporting, asymptomatic cases in sex partners often remain
unknown and untreated, with all the possible public health consequences. STDs
can be passed also from a mother to her baby before or during birth. Some of
these infections of the newborn can be cured easily, but others may cause a
baby to be permanently disabled and even die.
The
assessment shows that sexual partners of the survey respondents that were
infected with STDs have been treated only in about 26% of Gonorrhea cases, 42%
of cases of Chlamydial infection and 36% of cases of Trichomoniasis (Table
1.8.4). Many of these men even did not realized that their partners also were infected with the organism causing STDs. Only 165 (12%) men reported that their sex partners had STDs (Figure 1.8.4), which is much less than might be expected from they’re own history.
In
about 50% of mentioned STDs cases, men had no idea about the partner’s
treatment, and in 5% said that sex partners remained untreated (Table
1.8.5.).
Thus, results of this study indicate that the risk of spreading STDs, including HIV/AIDS, is very high in Armenia. The socio-economic and cultural realities of the present life in the country, together with the high migration rates, indicate an urgent need for STDs and AIDS control. |
