Richard J. Schmidt

Last updated

Richard J. Schmidt was an American former physician who was convicted by a Louisiana court in 1998 of attempted second degree murder for injecting his mistress, Janice Trahan, with human immunodeficiency virus (HIV). The case marked the first time in forensic history that viral RNA was used to prove a link between two people with HIV or acquired immune deficiency syndrome (AIDS) in a criminal trial. [1]

In 1994, Schmidt used a sample of blood taken from one of his HIV-positive patients to inject into his lover and former colleague, Janice Trahan, infecting her with HIV. Six months later, Trahan, a nurse, was diagnosed with HIV. Convinced that Schmidt had infected her after a suspiciously fleeting late-night visit to give her a "vitamin B" injection, [2] Trahan had her ex-husband and former sexual partners tested. All were shown to be negative for HIV—results which led Lafayette, Louisiana police to further investigate her claims. [3]

HIV is a fairly fragile RNA virus, and lasts for only a few hours outside the human body. Detectives examining hospital records found that Schmidt had taken blood from one patient that night, but had never sent the blood to the lab. [4] The absence of laboratory testing identification references against this patient's name led to police visiting the man who readily disclosed that he had AIDS and that he had been called in for a blood test by Schmidt on the evening in question. The forensic challenge at that point was to match the RNA from the virus itself from the patient to the victim, a process known as strain analysis that had never been attempted before. HIV RNA was collected from the victim, from the putative patient source, and from thirty-two other unrelated, HIV-positive individuals living in the same metropolitan area. Scientists concluded that of all the samples they tested, the two viruses' RNA from the victim and the patient matched almost exactly, even with HIV's potential to mutate very rapidly. [5]

It was further disclosed at trial that the victim had also acquired hepatitis C around the same time. [6] Evidence from Schmidt's patient records showed that a blood sample was taken from a patient with hepatitis C the day before the HIV-infected sample was taken. The hepatitis C sample was similarly not matched with any laboratory references – these two were the only such omissions found in Schmidt's patient records.

In 1998, Schmidt was sentenced to 50 years in prison for attempted second degree murder. [7]

In 2015, after 17 years served of his 50-year sentence, Schmidt was unanimously denied parole by the three-member State Board at a June hearing in Baton Rouge. [6]

On March, 3, 2023, the Louisiana Department of Public Safety & Corrections confirmed that Schmidt had died at a Baton Rouge hospital in Department of Corrections custody on February 12. Schmidt was 74. [8]

The human immunodeficiency viruses (HIV) are two species of Lentivirus that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.

<span class="mw-page-title-main">Hepatitis C</span> Human viral infection

Hepatitis C is an infectious disease caused by the hepatitis C virus (HCV) that primarily affects the liver; it is a type of viral hepatitis. During the initial infection period, people often have mild or no symptoms. Early symptoms can include fever, dark urine, abdominal pain, and yellow tinged skin. The virus persists in the liver, becoming chronic, in about 70% of those initially infected. Early on, chronic infection typically has no symptoms. Over many years however, it often leads to liver disease and occasionally cirrhosis. In some cases, those with cirrhosis will develop serious complications such as liver failure, liver cancer, or dilated blood vessels in the esophagus and stomach.

The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.

Viral load, also known as viral burden, is a numerical expression of the quantity of virus in a given volume of fluid, including biological and environmental specimens. It is not to be confused with viral titre or viral titer, which depends on the assay. When an assay for measuring the infective virus particle is done, viral titre often refers to the concentration of infectious viral particles, which is different from the total viral particles. Viral load is measured using body fluids sputum and blood plasma. As an example of environmental specimens, the viral load of norovirus can be determined from run-off water on garden produce. Norovirus has not only prolonged viral shedding and has the ability to survive in the environment but a minuscule infectious dose is required to produce infection in humans: less than 100 viral particles.

<span class="mw-page-title-main">Diagnosis of HIV/AIDS</span> Immunological test

HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes HIV/AIDS, in serum, saliva, or urine. Such tests may detect antibodies, antigens, or RNA.

The spread of HIV/AIDS has affected millions of people worldwide; AIDS is considered a pandemic. The World Health Organization (WHO) estimated that in 2016 there were 36.7 million people worldwide living with HIV/AIDS, with 1.8 million new HIV infections per year and 1 million deaths due to AIDS. Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development of AIDS. Below is a list and explanations of some common misconceptions and their rebuttals.

GB virus C (GBV-C), formerly known as hepatitis G virus (HGV) and also known as human pegivirus – HPgV is a virus in the family Flaviviridae and a member of the Pegivirus, is known to infect humans, but is not known to cause human disease. Reportedly, HIV patients coinfected with GBV-C can survive longer than those without GBV-C, but the patients may be different in other ways. Research is active into the virus' effects on the immune system in patients coinfected with GBV-C and HIV.

<span class="mw-page-title-main">Primary effusion lymphoma</span> Medical condition

Primary effusion lymphoma (PEL) is classified as a diffuse large B cell lymphoma. It is a rare malignancy of plasmablastic cells that occurs in individuals that are infected with the Kaposi's sarcoma-associated herpesvirus. Plasmablasts are immature plasma cells, i.e. lymphocytes of the B-cell type that have differentiated into plasmablasts but because of their malignant nature do not differentiate into mature plasma cells but rather proliferate excessively and thereby cause life-threatening disease. In PEL, the proliferating plasmablastoid cells commonly accumulate within body cavities to produce effusions, primarily in the pleural, pericardial, or peritoneal cavities, without forming a contiguous tumor mass. In rare cases of these cavitary forms of PEL, the effusions develop in joints, the epidural space surrounding the brain and spinal cord, and underneath the capsule which forms around breast implants. Less frequently, individuals present with extracavitary primary effusion lymphomas, i.e., solid tumor masses not accompanied by effusions. The extracavitary tumors may develop in lymph nodes, bone, bone marrow, the gastrointestinal tract, skin, spleen, liver, lungs, central nervous system, testes, paranasal sinuses, muscle, and, rarely, inside the vasculature and sinuses of lymph nodes. As their disease progresses, however, individuals with the classical effusion-form of PEL may develop extracavitary tumors and individuals with extracavitary PEL may develop cavitary effusions.

Taiwan's epidemic of HIV/AIDS began with the first case reported in December 1984. On 17 December 1990 the government promulgated the AIDS Prevention and Control Act. On 11 July 2007, the AIDS Prevention and Control Act was renamed the HIV Infection Control and Patient Rights Protection Act.

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection is a multi-faceted, chronic condition that significantly impacts public health. According to the World Health Organization (WHO), 2 to 15% of those infected with HIV are also affected by HCV, increasing their risk of morbidity and mortality due to accelerated liver disease. The burden of co-infection is especially high in certain high-risk groups, such as intravenous drug users and men who have sex with men. These individuals who are HIV-positive are commonly co-infected with HCV due to shared routes of transmission including, but not limited to, exposure to HIV-positive blood, sexual intercourse, and passage of the Hepatitis C virus from mother to infant during childbirth.

<i>Factor 8: The Arkansas Prison Blood Scandal</i> 2005 American film

Factor 8: The Arkansas Prison Blood Scandal is a feature-length documentary by Arkansas filmmaker and investigative journalist, Kelly Duda, released in 2005. Through interviews and the presentation of documents and footage, Duda alleged that in the 1970s and 1980s, the Arkansas prison system profited from selling blood plasma from inmates infected with viral hepatitis and HIV. The documentary contends that thousands of victims who received transfusions of blood products derived from these plasma products, Factor VIII, died as a result.

Contaminated hemophilia blood products were a serious public health problem in the late 1970s up to 1985.

<span class="mw-page-title-main">HIV/AIDS in Russia</span> Situation around HIV/AIDS in Russia

The situation with the spread of HIV/AIDS in Russia is described by some researchers as an epidemic. The first cases of human immunodeficiency virus infection were recorded in the USSR in 1985-1987. Patient zero is officially considered to be a military interpreter who worked in Tanzania in the early 1980s and was infected by a local man during sexual contact. After 1988—1989 Elista HIV outbreak, the disease became known to the general public and the first AIDS centers were established. In 1995-1996, the virus spread among injecting drug users (IDUs) and soon expanded throughout the country. By 2006, HIV had spread beyond the vulnerable IDU group, endangering their heterosexual partners and potentially the entire population.

With less than 1 percent of the population estimated to be HIV-positive, Egypt is a low-HIV-prevalence country. However, between the years 2006 and 2011, HIV prevalence rates in Egypt increased tenfold. Until 2011, the average number of new cases of HIV in Egypt was 400 per year, but in 2012 and 2013, it increased to about 600 new cases, and in 2014, it reached 880 new cases per year. According to 2016 statistics from UNAIDS, there are about 11,000 people currently living with HIV in Egypt. The Ministry of Health and Population reported in 2020 over 13,000 Egyptians are living with HIV/AIDS. However, unsafe behaviors among most-at-risk populations and limited condom usage among the general population place Egypt at risk of a broader epidemic.

A pin prick attack is an assault on another person with a needle or syringe tainted with the blood of somebody carrying a blood-borne disease, such as HIV. Although there have been numerous cases of people being attacked with needles and syringes, the idea that people infected with AIDS have deliberately attempted to infect others in this manner is generally considered an urban legend: Real cases of infection of HIV in this manner were typically taken from infected victims rather than from infected attackers.

<span class="mw-page-title-main">Infected blood scandal in the United Kingdom</span> The historical contamination of blood products in the UK with HIV and hepatitis C virus

From the 1970s to the early 1990s, tens of thousands of people were infected with hepatitis C and HIV as a result of receiving infected blood or infected clotting factor products in the United Kingdom. Many of the products were imported from the United States, and distributed to patients by the National Health Service. Most recipients had haemophilia or had received a blood transfusion following childbirth or surgery. It has been estimated that more than 30,000 patients received contaminated blood, resulting in the deaths of at least 3,000 people. In July 2017, Prime Minister Theresa May announced an independent public inquiry into the scandal, for which she was widely praised as successive governments going back to the 1980s had refused such an inquiry. May stated that "the victims and their families who have suffered so much pain and hardship deserve answers as to how this could possibly have happened." The final report was published in seven volumes on 20 May 2024, concluding that the scandal could have been largely avoided, patients were knowingly exposed to "unacceptable risks", and that doctors, the government and NHS tried to cover up what happened by "hiding the truth".

HIV in pregnancy is the presence of an HIV/AIDS infection in a woman while she is pregnant. There is a risk of HIV transmission from mother to child in three primary situations: pregnancy, childbirth, and while breastfeeding. This topic is important because the risk of viral transmission can be significantly reduced with appropriate medical intervention, and without treatment HIV/AIDS can cause significant illness and death in both the mother and child. This is exemplified by data from The Centers for Disease Control (CDC): In the United States and Puerto Rico between the years of 2014–2017, where prenatal care is generally accessible, there were 10,257 infants in the United States and Puerto Rico who were exposed to a maternal HIV infection in utero who did not become infected and 244 exposed infants who did become infected.

<i>HIV Haemophilia Litigation</i> Legal action by haemophiliacs infected with HIV through blood products

The HIV Haemophilia Litigation [1990] 41 BMLR 171, [1990] 140 NLJR 1349 (CA), [1989] E N. 2111, also known as AMcG002, and HHL, was a legal claim by 962 plaintiffs, mainly haemophiliacs, who were infected with HIV as a result of having been treated with blood products in the late 1970s and early 1980s. The first central defendants were the then Department of Health, with other defendants being the Licensing Authority of the time, (MCA), the CSM, the CBLA, and the regional health authorities of England and Wales. In total, there were 220 defendants in the action.
